The only requirement is that the format be + readable or writable as a stream and that each archive entry be + independent. There are articles on the libarchive Wiki explaining + how to extend libarchive. + + * On read, compression and format are always detected automatically. + + * I've attempted to minimize static link pollution. If you don't + explicitly invoke a particular feature (such as support for a + particular compression or format), it won't get pulled in. + In particular, if you don't explicitly enable a particular + compression or decompression support, you won't need to link + against the corresponding compression or decompression libraries. + This also reduces the size of statically-linked binaries in + environments where that matters. + + * On read, the library accepts whatever blocks you hand it. + Your read callback is free to pass the library a byte at a time + or mmap the entire archive and give it to the library at once. + On write, the library always produces correctly-blocked output. + + * The object-style approach allows you to have multiple archive streams + open at once. bsdtar uses this in its "@archive" extension. + + * The archive itself is read/written using callback functions. + You can read an archive directly from an in-memory buffer or + write it to a socket, if you wish. There are some utility + functions to provide easy-to-use "open file," etc, capabilities. + + * The read/write APIs are designed to allow individual entries + to be read or written to any data source: You can create + a block of data in memory and add it to a tar archive without + first writing a temporary file. You can also read an entry from + an archive and write the data directly to a socket. If you want + to read/write entries to disk, there are convenience functions to + make this especially easy. + + * Note: "pax interchange format" is really an extended tar format, + despite what the name says. diff --git a/archivers/libarchive/files/aclocal.m4 b/archivers/libarchive/files/aclocal.m4 new file mode 100644 index 00000000000..0cffd9cf73f --- /dev/null +++ b/archivers/libarchive/files/aclocal.m4 @@ -0,0 +1,8850 @@ +# generated automatically by aclocal 1.10.1 -*- Autoconf -*- + +# Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, +# 2005, 2006, 2007, 2008 Free Software Foundation, Inc. +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(AC_AUTOCONF_VERSION, [2.62],, +[m4_warning([this file was generated for autoconf 2.62. +You have another version of autoconf.

+\fB\%archive_entry_uname\fP(\fI\%struct\ archive_entry\ *\fP); +.SH DESCRIPTION +.ad l +These functions create and manipulate data objects that +represent entries within an archive. +You can think of a +Tn struct archive_entry +as a heavy-duty version of +Tn struct stat: +it includes everything from +Tn struct stat +plus associated pathname, textual group and user names, etc. +These objects are used by +\fBlibarchive\fP(3) +to represent the metadata associated with a particular +entry in an archive. +.SS Create and Destroy +There are functions to allocate, destroy, clear, and copy +\fIarchive_entry\fP +objects: +.RS 5 +.TP +\fB\%archive_entry_clear\fP() +Erases the object, resetting all internal fields to the +same state as a newly-created object. +This is provided to allow you to quickly recycle objects +without thrashing the heap. +.TP +\fB\%archive_entry_clone\fP() +A deep copy operation; all text fields are duplicated. +.TP +\fB\%archive_entry_free\fP() +Releases the +Tn struct archive_entry +object. +.TP +\fB\%archive_entry_new\fP() +Allocate and return a blank +Tn struct archive_entry +object. +.RE +.SS Set and Get Functions +Most of the functions here set or read entries in an object. +Such functions have one of the following forms: +.RS 5 +.TP +\fB\%archive_entry_set_XXXX\fP() +Stores the provided data in the object. +In particular, for strings, the pointer is stored, +not the referenced string. +.TP +\fB\%archive_entry_copy_XXXX\fP() +As above, except that the referenced data is copied +into the object. +.TP +\fB\%archive_entry_XXXX\fP() +Returns the specified data. +In the case of strings, a const-qualified pointer to +the string is returned. +.RE +String data can be set or accessed as wide character strings +or normal +\fIchar\fP +strings. +The functions that use wide character strings are suffixed with +\fB_w\fP. +Note that these are different representations of the same data: +For example, if you store a narrow string and read the corresponding +wide string, the object will transparently convert formats +using the current locale. +Similarly, if you store a wide string and then store a +narrow string for the same data, the previously-set wide string will +be discarded in favor of the new data. +.PP +There are a few set/get functions that merit additional description: +.RS 5 +.TP +\fB\%archive_entry_set_link\fP() +This function sets the symlink field if it is already set. +Otherwise, it sets the hardlink field. +.RE +.SS File Flags +File flags are transparently converted between a bitmap +representation and a textual format. +For example, if you set the bitmap and ask for text, the library +will build a canonical text format. +However, if you set a text format and request a text format, +you will get back the same text, even if it is ill-formed. +If you need to canonicalize a textual flags string, you should first set the +text form, then request the bitmap form, then use that to set the bitmap form. +Setting the bitmap format will clear the internal text representation +and force it to be reconstructed when you next request the text form. +.PP +The bitmap format consists of two integers, one containing bits +that should be set, the other specifying bits that should be +cleared. +Bits not mentioned in either bitmap will be ignored. +Usually, the bitmap of bits to be cleared will be set to zero. +In unusual circumstances, you can force a fully-specified set +of file flags by setting the bitmap of flags to clear to the complement +of the bitmap of flags to set. +(This differs from +\fBfflagstostr\fP(3), +which only includes names for set bits.) +Converting a bitmap to a textual string is a platform-specific +operation; bits that are not meaningful on the current platform +will be ignored. +.PP +The canonical text format is a comma-separated list of flag names. +The +\fB\%archive_entry_copy_fflags_text\fP() +and +\fB\%archive_entry_copy_fflags_text_w\fP() +functions parse the provided text and sets the internal bitmap values. +This is a platform-specific operation; names that are not meaningful +on the current platform will be ignored. +The function returns a pointer to the start of the first name that was not +recognized, or NULL if every name was recognized. +Note that every name--including names that follow an unrecognized name--will +be evaluated, and the bitmaps will be set to reflect every name that is +recognized. +(In particular, this differs from +\fBstrtofflags\fP(3), +which stops parsing at the first unrecognized name.) +.SS ACL Handling +XXX This needs serious help. +XXX +.PP +An +``Access Control List'' +(ACL) is a list of permissions that grant access to particular users or +groups beyond what would normally be provided by standard POSIX mode bits. +The ACL handling here addresses some deficiencies in the POSIX.1e draft 17 ACL +specification. +In particular, POSIX.1e draft 17 specifies several different formats, but +none of those formats include both textual user/group names and numeric +UIDs/GIDs. +.PP +XXX explain ACL stuff XXX +.SH SEE ALSO +.ad l +\fBarchive\fP(3) +.SH HISTORY +.ad l +The +\fB\%libarchive\fP +library

for reading streaming archives. +The general process is to first create the +Tn struct archive +object, set options, initialize the reader, iterate over the archive +headers and associated data, then close the archive and release all +resources. +The following summary describes the functions in approximately the +order they would be used: +.RS 5 +.TP +\fB\%archive_read_new\fP() +Allocates and initializes a +Tn struct archive +object suitable for reading from an archive. +.TP +\fB\%archive_read_support_compression_bzip2\fP(), +\fB\%archive_read_support_compression_compress\fP(), +\fB\%archive_read_support_compression_gzip\fP(), +\fB\%archive_read_support_compression_lzma\fP(), +\fB\%archive_read_support_compression_none\fP(), +\fB\%archive_read_support_compression_xz\fP() +Enables auto-detection code and decompression support for the +specified compression. +Returns +\fBARCHIVE_OK\fP +if the compression is fully supported, or +\fBARCHIVE_WARN\fP +if the compression is supported only through an external program. +Note that decompression using an external program is usually slower than +decompression through built-in libraries. +Note that +``none'' +is always enabled by default. +.TP +\fB\%archive_read_support_compression_all\fP() +Enables all available decompression filters. +.TP +\fB\%archive_read_support_compression_program\fP() +Data is fed through the specified external program before being dearchived. +Note that this disables automatic detection of the compression format, +so it makes no sense to specify this in conjunction with any other +decompression option. +.TP +\fB\%archive_read_support_compression_program_signature\fP() +This feeds data through the specified external program +but only if the initial bytes of the data match the specified +signature value. +.TP +\fB\%archive_read_support_format_all\fP(), +\fB\%archive_read_support_format_ar\fP(), +\fB\%archive_read_support_format_cpio\fP(), +\fB\%archive_read_support_format_empty\fP(), +\fB\%archive_read_support_format_iso9660\fP(), +\fB\%archive_read_support_format_mtree\fP(), +\fB\%archive_read_support_format_tar\fP(), +\fB\%archive_read_support_format_zip\fP() +Enables support---including auto-detection code---for the +specified archive format. +For example, +\fB\%archive_read_support_format_tar\fP() +enables support for a variety of standard tar formats, old-style tar, +ustar, pax interchange format, and many common variants. +For convenience, +\fB\%archive_read_support_format_all\fP() +enables support for all available formats. +Only empty archives are supported by default. +.TP +\fB\%archive_read_support_format_raw\fP() +The +``raw'' +format handler allows libarchive to be used to read arbitrary data. +It treats any data stream as an archive with a single entry. +The pathname of this entry is +``data ;'' +all other entry fields are unset. +This is not enabled by +\fB\%archive_read_support_format_all\fP() +in order to avoid erroneous handling of damaged archives. +.TP +\fB\%archive_read_set_filter_options\fP(), +\fB\%archive_read_set_format_options\fP(), +\fB\%archive_read_set_options\fP() +Specifies options that will be passed to currently-registered +filters (including decompression filters) and/or format readers. +The argument is a comma-separated list of individual options. +Individual options have one of the following forms: +.RS 5 +.TP +\fIoption=value\fP +The option/value pair will be provided to every module. +Modules that do not accept an option with this name will ignore it. +.TP +\fIoption\fP +The option will be provided to every module with a value of +``1''. +.TP +\fI!option\fP +The option will be provided to every module with a NULL value. +.TP +\fImodule:option=value\fP, \fImodule:option\fP, \fImodule:!option\fP +As above, but the corresponding option and value will be provided +only to modules whose name matches +\fImodule\fP. +.RE +The return value will be +\fBARCHIVE_OK\fP +if any module accepts the option, or +\fBARCHIVE_WARN\fP +if no module accepted the option, or +\fBARCHIVE_FATAL\fP +if there was a fatal error while attempting to process the option. +.PP +The currently supported options are: +.RS 5 +.TP +Format iso9660 +.RS 5 +.TP +\fBjoliet\fP +Support Joliet extensions. +Defaults to enabled, use +\fB!joliet\fP +to disable. +.RE +.RE +.TP +\fB\%archive_read_open\fP() +The same as +\fB\%archive_read_open2\fP(), +except that the skip callback is assumed to be +.BR NULL. +.TP +\fB\%archive_read_open2\fP() +Freeze the settings, open the archive, and prepare for reading entries. +This is the most generic version of this call, which accepts +four callback functions. +Most clients will want to use +\fB\%archive_read_open_filename\fP(), +\fB\%archive_read_open_FILE\fP(), +\fB\%archive_read_open_fd\fP(), +or +\fB\%archive_read_open_memory\fP() +instead. +The library invokes the client-provided functions to obtain +raw bytes from the archive. +.TP +\fB\%archive_read_open_FILE\fP() +Like +\fB\%archive_read_open\fP(), +except that it accepts a +\fIFILE *\fP +pointer. +This function should not be used with tape drives or other devices +that require strict I/O blocking. +.TP +\fB\%archive_read_open_fd\fP() +Like +\fB\%archive_read_open\fP(), +except that it accepts a file descriptor and block size rather than +a set of function pointers. +Note that the file descriptor will not be automatically closed at +end-of-archive. +This function is safe for use with tape drives or other blocked devices. +.TP +\fB\%archive_read_open_file\fP() +This is a deprecated synonym for +\fB\%archive_read_open_filename\fP(). +.TP +\fB\%archive_read_open_filename\fP() +Like +\fB\%archive_read_open\fP(), +except that it accepts a simple filename and a block size. +A NULL filename represents standard input. +This function is safe for use with tape drives or other blocked devices. +.TP +\fB\%archive_read_open_memory\fP() +Like +\fB\%archive_read_open\fP(), +except that it accepts a pointer and size of a block of +memory containing the archive data. +.TP +\fB\%archive_read_next_header\fP() +Read the header for the next entry and return a pointer to +a +Tn struct archive_entry. +This is a convenience wrapper around +\fB\%archive_read_next_header2\fP() +that reuses an internal +Tn struct archive_entry +object for each request. +.TP +\fB\%archive_read_next_header2\fP() +Read the header for the next entry and populate the provided +Tn struct archive_entry. +.TP +\fB\%archive_read_data\fP() +Read data associated with the header just read. +Internally, this is a convenience function that calls +\fB\%archive_read_data_block\fP() +and fills any gaps with nulls so that callers see a single +continuous stream of data. +.TP +\fB\%archive_read_data_block\fP() +Return the next available block of data for this entry. +Unlike +\fB\%archive_read_data\fP(), +the +\fB\%archive_read_data_block\fP() +function avoids copying data and allows you to correctly handle +sparse files, as supported by some archive formats. +The library guarantees that offsets will increase and that blocks +will not overlap. +Note that the blocks returned from this function can be much larger +than the block size read from disk, due to compression +and internal buffer optimizations. +.TP +\fB\%archive_read_data_skip\fP() +A convenience function that repeatedly calls +\fB\%archive_read_data_block\fP() +to skip all of the data for this archive entry. +.TP +\fB\%archive_read_data_into_buffer\fP() +This function is deprecated and will be removed. +Use +\fB\%archive_read_data\fP() +instead. +.TP +\fB\%archive_read_data_into_fd\fP() +A convenience function that repeatedly calls +\fB\%archive_read_data_block\fP() +to copy the entire entry to the provided file descriptor. +.TP +\fB\%archive_read_extract\fP(), \fB\%archive_read_extract_set_skip_file\fP() +A convenience function that wraps the corresponding +\fBarchive_write_disk\fP(3) +interfaces. +The first call to +\fB\%archive_read_extract\fP() +creates a restore object using +\fBarchive_write_disk_new\fP(3) +and +\fBarchive_write_disk_set_standard_lookup\fP(3), +then transparently invokes +\fBarchive_write_disk_set_options\fP(3), +\fBarchive_write_header\fP(3), +\fBarchive_write_data\fP(3), +and +\fBarchive_write_finish_entry\fP(3) +to create the entry on disk and copy data into it. +The +\fIflags\fP +argument is passed unmodified to +\fBarchive_write_disk_set_options\fP(3). +.TP +\fB\%archive_read_extract2\fP() +This is another version of +\fB\%archive_read_extract\fP() +that allows you to provide your own restore object. +In particular, this allows you to override the standard lookup functions +using +\fBarchive_write_disk_set_group_lookup\fP(3), +and +\fBarchive_write_disk_set_user_lookup\fP(3). +Note that +\fB\%archive_read_extract2\fP() +does not accept a +\fIflags\fP +argument; you should use +\fB\%archive_write_disk_set_options\fP() +to set the restore options yourself. +.TP +\fB\%archive_read_extract_set_progress_callback\fP() +Sets a pointer to a user-defined callback that can be used +for updating progress displays during extraction. +The progress function will be invoked during the extraction of large +regular files. +The progress function will be invoked with the pointer provided to this call. +Generally, the data pointed to should include a reference to the archive +object and the archive_entry object so that various statistics +can be retrieved for the progress display. +.TP +\fB\%archive_read_close\fP() +Complete the archive and invoke the close callback. +.TP +\fB\%archive_read_finish\fP() +Invokes +\fB\%archive_read_close\fP() +if it was not invoked manually, then release all resources. +Note: In libarchive 1.x, this function was declared to return +\fIvoid ,\fP +which made it impossible to detect certain errors when +\fB\%archive_read_close\fP() +was invoked implicitly from this function. +The declaration is corrected beginning with libarchive 2.0. +.RE +.PP +Note that the library determines most of the relevant information about +the archive by inspection. +In particular, it automatically detects +\fBgzip\fP(1) +or +\fBbzip2\fP(1) +compression and transparently performs the appropriate decompression. +It also automatically detects the archive format. +.PP +A complete description of the +Tn struct archive +and +Tn struct archive_entry +objects can be found in the overview manual page for +\fBlibarchive\fP(3). +.SH CLIENT CALLBACKS +.ad l +The callback functions must match the following prototypes: +.RS 5 +.IP +\fItypedef ssize_t\fP +\fB\%archive_read_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP, \fI\%const\ void\ **buffer\fP) +.IP +\fItypedef int\fP

\fI\%void\ *client_data\fP) +.IP +\fItypedef int\fP +\fB\%archive_close_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP) +.RE +.PP +The open callback is invoked by +\fB\%archive_open\fP(). +It should return +\fBARCHIVE_OK\fP +if the underlying file or data source is successfully +opened. +If the open fails, it should call +\fB\%archive_set_error\fP() +to register an error code and message and return +\fBARCHIVE_FATAL\fP. +.PP +The read callback is invoked whenever the library +requires raw bytes from the archive. +The read callback should read data into a buffer, +set the +.RS 4 +const void **buffer +.RE +argument to point to the available data, and +return a count of the number of bytes available. +The library will invoke the read callback again +only after it has consumed this data. +The library imposes no constraints on the size +of the data blocks returned. +On end-of-file, the read callback should +return zero. +On error, the read callback should invoke +\fB\%archive_set_error\fP() +to register an error code and message and +return -1. +.PP +The skip callback is invoked when the +library wants to ignore a block of data. +The return value is the number of bytes actually +skipped, which may differ from the request. +If the callback cannot skip data, it should return +zero. +If the skip callback is not provided (the +function pointer is +.BR NULL ), +the library will invoke the read function +instead and simply discard the result. +A skip callback can provide significant +performance gains when reading uncompressed +archives from slow disk drives or other media +that can skip quickly. +.PP +The close callback is invoked by archive_close when +the archive processing is complete. +The callback should return +\fBARCHIVE_OK\fP +on success. +On failure, the callback should invoke +\fB\%archive_set_error\fP() +to register an error code and message and +return +\fBARCHIVE_FATAL.\fP +.SH EXAMPLE +.ad l +The following illustrates basic usage of the library. +In this example, +the callback functions are simply wrappers around the standard +\fBopen\fP(2), +\fBread\fP(2), +and +\fBclose\fP(2) +system calls. +.RS 4 +.nf +void +list_archive(const char *name) +{ + struct mydata *mydata; + struct archive *a; + struct archive_entry *entry; + mydata = malloc(sizeof(struct mydata)); + a =

+.SH RETURN VALUES +.ad l +Most functions return zero on success, non-zero on error. +The possible return codes include: +\fBARCHIVE_OK\fP +(the operation succeeded), +\fBARCHIVE_WARN\fP +(the operation succeeded but a non-critical error was encountered), +\fBARCHIVE_EOF\fP +(end-of-archive was encountered), +\fBARCHIVE_RETRY\fP +(the operation failed but can be retried), +and +\fBARCHIVE_FATAL\fP +(there was a fatal error; the archive should be closed immediately). +Detailed error codes and textual descriptions are available from the +\fB\%archive_errno\fP() +and +\fB\%archive_error_string\fP() +functions. +.PP +\fB\%archive_read_new\fP() +returns a pointer to a freshly allocated +Tn struct archive +object. +It returns +.BR NULL +on error. +.PP +\fB\%archive_read_data\fP() +returns a count of bytes actually read or zero at the end of the entry. +On error, a value of +\fBARCHIVE_FATAL\fP, +\fBARCHIVE_WARN\fP, +or +\fBARCHIVE_RETRY\fP +is returned and an error code and textual description can be retrieved from the +\fB\%archive_errno\fP() +and +\fB\%archive_error_string\fP() +functions. +.PP +The library expects the client callbacks to behave similarly. +If there is an error, you can use +\fB\%archive_set_error\fP() +to set an appropriate error code and description, +then return one of the non-zero values above. +(Note that the value eventually returned to the client may +not be the same; many errors that are not critical at the level +of basic I/O can prevent the archive from being properly read, +thus most I/O errors eventually cause +\fBARCHIVE_FATAL\fP +to be returned.) +.SH SEE ALSO +.ad l +\fBtar\fP(1), +\fBarchive\fP(3), +\fBarchive_util\fP(3), +\fBtar\fP(5) +.SH HISTORY +.ad l +The +\fB\%libarchive\fP

+.br +\fB\%archive_write_finish\fP(\fI\%struct\ archive\ *\fP); +.SH DESCRIPTION +.ad l +These functions provide a complete API for creating streaming +archive files. +The general process is to first create the +Tn struct archive +object, set any desired options, initialize the archive, append entries, then +close the archive and release all resources. +The following summary describes the functions in approximately +the order they are ordinarily used: +.RS 5 +.TP +\fB\%archive_write_new\fP() +Allocates and initializes a +Tn struct archive +object suitable for writing a tar archive. +.TP +\fB\%archive_write_set_bytes_per_block\fP() +Sets the block size used for writing the archive data. +Every call to the write callback function, except possibly the last one, will +use this value for the length. +The third parameter is a boolean that specifies whether or not the final block +written will be padded to the full block size. +If it is zero, the last block will not be padded. +If it is non-zero, padding will be added both before and after compression. +The default is to use a block size of 10240 bytes and to pad the last block. +Note that a block size of zero will suppress internal blocking +and cause writes to be sent directly to the write callback as they occur. +.TP +\fB\%archive_write_get_bytes_per_block\fP() +Retrieve the block size to be used for writing. +A value of -1 here indicates that the library should use default values. +A value of zero indicates that internal blocking is suppressed. +.TP +\fB\%archive_write_set_bytes_in_last_block\fP() +Sets the block size used for writing the last block. +If this value is zero, the last block will be padded to the same size +as the other blocks. +Otherwise, the final block will be padded to a multiple of this size. +In particular, setting it to 1 will cause the final block to not be padded. +For compressed output, any padding generated by this option +is applied only after the compression. +The uncompressed data is always unpadded. +The default is to pad the last block to the full block size (note that +\fB\%archive_write_open_filename\fP() +will set this based on the file type). +Unlike the other +``set'' +functions, this function can be called after the archive is opened. +.TP +\fB\%archive_write_get_bytes_in_last_block\fP() +Retrieve the currently-set value for last block size. +A value of -1 here indicates that the library should use default values. +.TP +\fB\%archive_write_set_format_cpio\fP(), +\fB\%archive_write_set_format_pax\fP(), +\fB\%archive_write_set_format_pax_restricted\fP(), +\fB\%archive_write_set_format_shar\fP(), +\fB\%archive_write_set_format_shar_binary\fP(), +\fB\%archive_write_set_format_ustar\fP() +Sets the format that will be used for the archive. +The library can write +POSIX octet-oriented cpio format archives, +POSIX-standard +``pax interchange'' +format archives, +traditional +``shar'' +archives, +enhanced +``binary'' +shar archives that store a variety of file attributes and handle binary files, +and +POSIX-standard +``ustar'' +archives. +The pax interchange format is a backwards-compatible tar format that +adds key/value attributes to each entry and supports arbitrary +filenames, linknames, uids, sizes, etc. +``Restricted pax interchange format'' +is the library default; this is the same as pax format, but suppresses +the pax extended header for most normal files. +In most cases, this will result in ordinary ustar archives. +.TP +\fB\%archive_write_set_compression_bzip2\fP(), +\fB\%archive_write_set_compression_compress\fP(), +\fB\%archive_write_set_compression_gzip\fP(), +\fB\%archive_write_set_compression_none\fP() +The resulting archive will be compressed as specified. +Note that the compressed output is always properly blocked. +.TP +\fB\%archive_write_set_compression_program\fP() +The archive will be fed into the specified compression program. +The output of that program is blocked and written to the client +write callbacks. +.TP +\fB\%archive_write_set_compressor_options\fP(), +\fB\%archive_write_set_format_options\fP(), +\fB\%archive_write_set_options\fP() +Specifies options that will be passed to the currently-enabled +compressor and/or format writer. +The argument is a comma-separated list of individual options. +Individual options have one of the following forms: +.RS 5 +.TP +\fIoption=value\fP +The option/value pair will be provided to every module. +Modules that do not accept an option with this name will ignore it. +.TP +\fIoption\fP +The option will be provided to every module with a value of +``1''. +.TP +\fI!option\fP +The option will be provided to every module with a NULL value. +.TP +\fImodule:option=value\fP, \fImodule:option\fP, \fImodule:!option\fP +As above, but the corresponding option and value will be provided +only to modules whose name matches +\fImodule\fP. +.RE +The return value will be +\fBARCHIVE_OK\fP +if any module accepts the option, or +\fBARCHIVE_WARN\fP +if no module accepted the option, or +\fBARCHIVE_FATAL\fP +if there was a fatal error while attempting to process the option. +.PP +The currently supported options are: +.RS 5 +.TP +Compressor gzip +.RS 5 +.TP +\fBcompression-level\fP +The value is interpreted as a decimal integer specifying the +gzip compression level. +.RE +.TP +Compressor xz +.RS 5 +.TP +\fBcompression-level\fP +The value is interpreted as a decimal integer specifying the +compression level. +.RE +.TP +Format mtree +.RS 5 +.TP +\fBcksum\fP,

\fBtime\fP, \fBuid\fP, \fBuname\fP +Enable a particular keyword in the mtree output. +Prefix with an exclamation mark to disable the corresponding keyword. +The default is equivalent to +``device, flags, gid, gname, link, mode, nlink, size, time, type, uid, uname''. +.TP +\fBall\fP +Enables all of the above keywords. +.TP +\fBuse-set\fP +Enables generation of +\fB/set\fP +lines that specify default values for the following files and/or directories. +.TP +\fBindent\fP +XXX needs explanation XXX +.RE +.RE +.TP +\fB\%archive_write_open\fP() +Freeze the settings, open the archive, and prepare for writing entries. +This is the most generic form of this function, which accepts +pointers to three callback functions which will be invoked by +the compression layer to write the constructed archive. +.TP +\fB\%archive_write_open_fd\fP() +A convenience form of +\fB\%archive_write_open\fP() +that accepts a file descriptor. +The +\fB\%archive_write_open_fd\fP() +function is safe for use with tape drives or other +block-oriented devices. +.TP +\fB\%archive_write_open_FILE\fP() +A convenience form of +\fB\%archive_write_open\fP() +that accepts a +\fIFILE *\fP +pointer. +Note that +\fB\%archive_write_open_FILE\fP() +is not safe for writing to tape drives or other devices +that require correct blocking. +.TP +\fB\%archive_write_open_file\fP() +A deprecated synonym for +\fB\%archive_write_open_filename\fP(). +.TP +\fB\%archive_write_open_filename\fP() +A convenience form of +\fB\%archive_write_open\fP() +that accepts a filename. +A NULL argument indicates that the output should be written to standard output; +an argument of +``-'' +will open a file with that name. +If you have not invoked +\fB\%archive_write_set_bytes_in_last_block\fP(), +then +\fB\%archive_write_open_filename\fP() +will adjust the last-block padding depending on the file: +it will enable padding when writing to standard output or +to a character or block device node, it will disable padding otherwise. +You can override this by manually invoking +\fB\%archive_write_set_bytes_in_last_block\fP() +before calling +\fB\%archive_write_open\fP(). +The +\fB\%archive_write_open_filename\fP() +function is safe for use with tape drives or other +block-oriented devices. +.TP +\fB\%archive_write_open_memory\fP() +A convenience form of +\fB\%archive_write_open\fP() +that accepts a pointer to a block of memory that will receive +the archive. +The final +\fIsize_t *\fP +argument points to a variable that will be updated +after each write to reflect how much of the buffer +is currently in use. +You should be careful to ensure that this variable +remains allocated until after the archive is +closed. +.TP +\fB\%archive_write_header\fP() +Build and write a header using the data in the provided +Tn struct archive_entry +structure. +See +\fBarchive_entry\fP(3) +for information on creating and populating +Tn struct archive_entry +objects. +.TP +\fB\%archive_write_data\fP() +Write data corresponding to the header just written. +Returns number of bytes written or -1 on error. +.TP +\fB\%archive_write_finish_entry\fP() +Close out the entry just written. +In particular, this writes out the final padding required by some formats. +Ordinarily, clients never need to call this, as it +is called automatically by +\fB\%archive_write_next_header\fP() +and +\fB\%archive_write_close\fP() +as needed. +.TP +\fB\%archive_write_close\fP() +Complete the archive and invoke the close callback. +.TP +\fB\%archive_write_finish\fP() +Invokes +\fB\%archive_write_close\fP() +if it was not invoked manually, then releases all resources. +Note that this function was declared to return +\fIvoid\fP +in libarchive 1.x, which made it impossible to detect errors when +\fB\%archive_write_close\fP() +was invoked implicitly from this function. +This is corrected beginning with libarchive 2.0. +.RE +More information about the +\fIstruct\fP archive +object and the overall design of the library can be found in the +\fBlibarchive\fP(3) +overview. +.SH IMPLEMENTATION +.ad l +Compression support is built-in to libarchive, which uses zlib and bzlib +to handle gzip and bzip2 compression, respectively. +.SH CLIENT CALLBACKS +.ad l +To use this library, you will need to define and register +callback functions that will be invoked to write data to the +resulting archive. +These functions are registered by calling +\fB\%archive_write_open\fP(): +.RS 5 +.IP +\fItypedef int\fP +\fB\%archive_open_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP) +.RE +.PP +The open callback is invoked by +\fB\%archive_write_open\fP(). +It should return +\fBARCHIVE_OK\fP +if the underlying file or data source is successfully +opened. +If the open fails, it should call +\fB\%archive_set_error\fP() +to register an error code and message and return +\fBARCHIVE_FATAL\fP. +.RS 5 +.IP +\fItypedef ssize_t\fP +\fB\%archive_write_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP, \fI\%const\ void\ *buffer\fP, \fI\%size_t\ length\fP) +.RE +.PP +The write callback is invoked whenever the library +needs to write raw bytes to the archive. +For correct blocking, each call to the write callback function +should translate into a single +\fBwrite\fP(2) +system call. +This is especially critical when writing archives to tape drives. +On success, the write callback should return the +number of bytes actually written. +On error, the callback should invoke +\fB\%archive_set_error\fP() +to register an error code and message and return -1. +.RS 5 +.IP +\fItypedef int\fP +\fB\%archive_close_callback\fP(\fI\%struct\ archive\ *\fP, \fI\%void\ *client_data\fP) +.RE +.PP +The close callback is invoked by archive_close when +the archive processing is complete. +The callback should return +\fBARCHIVE_OK\fP +on success. +On failure, the callback should invoke +\fB\%archive_set_error\fP() +to register an error code and message and +return +\fBARCHIVE_FATAL.\fP +.SH EXAMPLE +.ad l +The following sketch illustrates basic usage of the library. +In this example, +the callback functions are simply wrappers around the standard +\fBopen\fP(2), +\fBwrite\fP(2), +and +\fBclose\fP(2) +system calls. +.RS 4 +.nf +#ifdef __linux__ +#define

+\fBARCHIVE_OK\fP +(zero) on success, or one of several non-zero +error codes for errors. +Specific error codes include: +\fBARCHIVE_RETRY\fP +for operations that might succeed if retried, +\fBARCHIVE_WARN\fP +for unusual conditions that do not prevent further operations, and +\fBARCHIVE_FATAL\fP +for serious errors that make remaining operations impossible. +The +\fB\%archive_errno\fP() +and +\fB\%archive_error_string\fP() +functions can be used to retrieve an appropriate error code and a +textual error message. +.PP +\fB\%archive_write_new\fP() +returns a pointer to a newly-allocated +Tn struct archive +object. +.PP +\fB\%archive_write_data\fP() +returns a count of the number of bytes actually written. +On error, -1 is returned and the +\fB\%archive_errno\fP() +and +\fB\%archive_error_string\fP() +functions will return appropriate values. +Note that if the client-provided write callback function +returns a non-zero value, that error will be propagated back to the caller +through whatever API function resulted in that call, which +may include +\fB\%archive_write_header\fP(), +\fB\%archive_write_data\fP(), +\fB\%archive_write_close\fP(), +or +\fB\%archive_write_finish\fP(). +The client callback can call +\fB\%archive_set_error\fP() +to provide values that can then be retrieved by

that may cause +certain programs to reject archives written by this library. +For example, several historic implementations calculated header checksums +incorrectly and will thus reject valid archives; GNU tar does not fully support +pax interchange format; some old tar implementations required specific +field terminations. +.PP +The default pax interchange format eliminates most of the historic +tar limitations and provides a generic key/value attribute facility +for vendor-defined extensions. +One oversight in POSIX is the failure to provide a standard attribute +for large device numbers. +This library uses +``SCHILY.devminor'' +and +``SCHILY.devmajor'' +for device numbers that exceed the range supported by the backwards-compatible +ustar header. +These keys are compatible with Joerg Schilling's +\fB\%star\fP +archiver. +Other implementations may not recognize these keys and will thus be unable +to correctly restore device nodes with large device numbers from archives

complete API for creating objects on +disk from +Tn struct archive_entry +descriptions. +They are most naturally used when extracting objects from an archive +using the +\fB\%archive_read\fP() +interface. +The general process is to read +Tn struct archive_entry +objects from an archive, then write those objects to a +Tn struct archive +object created using the +\fB\%archive_write_disk\fP() +family functions. +This interface is deliberately very similar to the +\fB\%archive_write\fP() +interface used to write objects to a streaming archive. +.RS 5 +.TP +\fB\%archive_write_disk_new\fP() +Allocates and initializes a +Tn struct archive +object suitable for writing objects to disk. +.TP +\fB\%archive_write_disk_set_skip_file\fP() +Records the device and inode numbers of a file that should not be +overwritten. +This is typically used to ensure that an extraction process does not +overwrite the archive from which objects are being read. +This capability is technically unnecessary but can be a significant +performance optimization in practice. +.TP +\fB\%archive_write_disk_set_options\fP() +The options field consists of a bitwise OR of one or more of the +following values: +.RS 5 +.TP +\fBARCHIVE_EXTRACT_OWNER\fP +The user and group IDs should be set on the restored file. +By default, the user and group IDs are not restored. +.TP +\fBARCHIVE_EXTRACT_PERM\fP +Full permissions (including SGID, SUID, and sticky bits) should +be restored exactly as specified, without obeying the +current umask. +Note that SUID and SGID bits can only be restored if the +user and group ID of the object on disk are correct. +If +\fBARCHIVE_EXTRACT_OWNER\fP +is not specified, then SUID and SGID bits will only be restored +if the default user and group IDs of newly-created objects on disk +happen to match those specified in the archive entry. +By default, only basic permissions are restored, and umask is obeyed. +.TP +\fBARCHIVE_EXTRACT_TIME\fP +The timestamps (mtime, ctime, and atime) should be restored. +By default, they are ignored. +Note that restoring of atime is not currently supported. +.TP +\fBARCHIVE_EXTRACT_NO_OVERWRITE\fP +Existing files on disk will not be overwritten. +By default, existing regular files are truncated and overwritten; +existing directories will have their permissions updated; +other pre-existing objects are unlinked and recreated from scratch. +.TP +\fBARCHIVE_EXTRACT_UNLINK\fP +Existing files on disk will be unlinked before any attempt to +create them. +In some cases, this can prove to be a significant performance improvement. +By default, existing files are truncated and rewritten, but +the file is not recreated. +In particular, the default behavior does not break existing hard links. +.TP +\fBARCHIVE_EXTRACT_ACL\fP +Attempt to restore

+Directories are created during +\fB\%archive_write_header\fP(), +but final permissions are not set until +\fB\%archive_write_close\fP(). +This separation is necessary to correctly handle borderline +cases such as a non-writable directory containing +files, but can cause unexpected results. +In particular, directory permissions are not fully +restored until the archive is closed. +If you use +\fBchdir\fP(2) +to change the current directory between calls to +\fB\%archive_read_extract\fP() +or before calling +\fB\%archive_read_close\fP(), +you may confuse the permission-setting logic with +the result that directory permissions are restored +incorrectly. +.PP +The library attempts to create objects with filenames longer than +\fBPATH_MAX\fP +by creating prefixes of the full path and changing the current directory. +Currently, this logic is limited in scope; the fixup pass does +not work correctly for such objects and the symlink security check +option disables the support for very long pathnames. +.PP +Restoring the path +\fIaa/../bb\fP +does create each intermediate directory. +In particular, the directory +\fIaa\fP +is created as well as the final object +\fIbb\fP. +In theory, this can be exploited to create an entire directory heirarchy +with a single request. +Of course, this does not work if the +\fBARCHIVE_EXTRACT_NODOTDOT\fP +option is specified. +.PP +Implicit directories are always created obeying the current umask. +Explicit objects are created obeying the current umask unless +\fBARCHIVE_EXTRACT_PERM\fP +is specified, in which case they current umask is ignored. +.PP +SGID and SUID bits are restored only if the correct user and +group could be set. +If +\fBARCHIVE_EXTRACT_OWNER\fP +is not specified, then no attempt is made to set the ownership. +In this case, SGID and SUID bits are restored only if the +user and group of the final object happen to match those specified +in the entry. +.PP +The +``standard'' +user-id and group-id lookup functions are not the defaults because +\fBgetgrnam\fP(3) +and +\fBgetpwnam\fP(3) +are sometimes too large for particular applications. +The current design allows the application author to use a more +compact implementation when appropriate. +.PP +There should be a corresponding +\fB\%archive_read_disk\fP +interface that walks a directory heirarchy and returns archive +entry objects. diff --git

carefully-crafted archives can request that +\fB\%tar\fP +extract files to locations outside of the target directory. +This can potentially be used to cause unwitting users to overwrite +files they did not intend to overwrite. +If the archive is being extracted by the superuser, any file +on the system can potentially be overwritten. +There are three ways this can happen. +Although +\fB\%tar\fP +has mechanisms to protect against each one, +savvy users should be aware of the implications: +.RS 5 +.IP \(bu +Archive entries can have absolute pathnames. +By default, +\fB\%tar\fP +removes the leading +\fI/\fP +character from filenames before restoring them to guard against this problem. +.IP \(bu +Archive entries can have pathnames that include +\fI\& ..\fP +components. +By default, +\fB\%tar\fP +will not extract files containing +\fI\& ..\fP +components in their pathname. +.IP \(bu +Archive entries can exploit symbolic links to restore +files to other directories. +An archive can restore a symbolic link to another directory, +then use that link to restore a file into that directory. +To guard against this, +\fB\%tar\fP +checks each extracted path for symlinks. +If the final path element is a symlink, it will be removed +and replaced with the archive entry. +If +\fB\-U\fP +is specified, any intermediate symlink will also be unconditionally removed. +If neither +\fB\-U\fP +nor +\fB\-P\fP +is specified, +\fB\%tar\fP +will refuse to extract the entry. +.RE +To protect yourself, you should be wary of any archives that +come from untrusted sources. +You should examine the contents of an archive with +.RS 4 +\fB\%tar\fP \fB\-tf\fP \fIfilename\fP +.RE +before extraction. +You should use the +\fB\-k\fP +option to ensure that +\fB\%tar\fP +will not overwrite any existing files or the +\fB\-U\fP +option to remove any pre-existing files. +You should generally not extract archives while running with super-user +privileges. +Note that the +\fB\-P\fP +option to +\fB\%tar\fP +disables the security checks above and allows you to extract +an archive while preserving any absolute pathnames, +\fI\& ..\fP +components, or symlinks to other directories. +.SH SEE

+was quite influential, and formed the basis of GNU tar. +GNU tar was included as the standard system tar +in +FreeBSD +beginning with +FreeBSD 1.0. +.PP +This is a complete re-implementation based on the +\fBlibarchive\fP(3) +library. +.SH BUGS +.ad l +This program follows +ISO/IEC 9945-1:1996 (``POSIX.1'') +for the definition of the +\fB\-l\fP +option. +Note that GNU tar prior to version 1.15 treated +\fB\-l\fP +as a synonym for the +\fB\--one-file-system\fP +option. +.PP +The +\fB\-C\fP \fIdir\fP +option may differ from historic implementations. +.PP +All archive output is written in correctly-sized blocks, even +if the output is being compressed. +Whether or not the last output block is padded to a full +block size varies depending on the format and the +output device. +For tar and cpio formats, the last block of output is padded +to a full block size if the output is being +written to standard output or to a character or block device such as +a tape drive. +If the output is being written to a regular file, the last block +will not be padded. +Many compressors, including +\fBgzip\fP(1) +and +\fBbzip2\fP(1), +complain about the null padding when decompressing an archive created by +\fB\%tar\fP, +although they still extract it correctly. +.PP +The compression and decompression is implemented internally, so +there may be insignificant differences between the compressed

write archives to the standard I/O paths, +but tradition (and POSIX) dictates otherwise. +.PP +The +\fBr\fP +and +\fBu\fP +modes require that the archive be uncompressed +and located in a regular file

by the libarchive library +.SH DESCRIPTION +.ad l +The +\fBlibarchive\fP(3) +library reads and writes a variety of streaming archive formats. +Generally speaking, all of these archive formats consist of a series of +``entries''. +Each entry stores a single file system object, such as a file, directory, +or symbolic link. +.PP +The following provides a brief description of each format supported +by libarchive, with some information about recognized extensions or +limitations of the current library support. +Note that just because a format is supported by libarchive does not +imply that a program that uses libarchive will support that format. +Applications that use libarchive specify which formats they wish +to support, though many programs do use libarchive convenience +functions to enable all supported formats. +.SS Tar Formats +The +\fBlibarchive\fP(3) +library can read most tar archives. +However, it only writes POSIX-standard +``ustar'' +and +``pax interchange'' +formats. +.PP +All tar formats store each entry in one or more 512-byte records. +The first record is used for file metadata, including filename, +timestamp, and mode information, and the file data is stored in +subsequent records. +Later variants have extended this by either appropriating undefined +areas of the header record, extending the header to multiple records, +or by storing special entries that modify the interpretation of +subsequent entries. +.PP +.RS 5 +.TP +\fBgnutar\fP +The +\fBlibarchive\fP(3) +library can read GNU-format tar archives. +It currently supports the most popular GNU extensions, including +modern long filename and linkname support, as well as atime and ctime data. +The libarchive library does not support multi-volume +archives, nor the old GNU long filename format. +It can read GNU sparse file entries, including the new POSIX-based +formats, but cannot write GNU sparse file entries. +.TP +\fBpax\fP +The +\fBlibarchive\fP(3) +library can read and write POSIX-compliant pax interchange format +archives. +Pax interchange format archives are an extension of the older ustar +format that adds a separate entry with additional attributes stored +as key/value pairs immediately before each regular entry. +The presence of these additional entries is the only difference between +pax interchange format and the older ustar format. +The extended attributes are of unlimited length and are stored +as UTF-8 Unicode strings. +Keywords defined in the standard are in all lowercase; vendors are allowed +to define custom keys by preceding them with the vendor name in all uppercase. +When writing pax archives, libarchive uses many of the SCHILY keys +defined by Joerg Schilling's +``star'' +archiver and a few LIBARCHIVE keys. +The libarchive library can read most of the SCHILY keys +and most of the GNU keys introduced by GNU tar. +It silently ignores any keywords that it does not understand. +.TP +\fBrestricted\fP pax +The libarchive library can also write pax archives in which it +attempts to suppress the extended attributes entry whenever +possible. +The result will be identical to a ustar archive unless the +extended attributes entry is required to store a long file +name, long linkname, extended ACL, file flags, or if any of the standard +ustar data (user name, group name, UID, GID, etc) cannot be fully +represented in the ustar header. +In all cases, the result can be dearchived by any program that +can read POSIX-compliant pax interchange format archives. +Programs that correctly read ustar format (see below) will also be +able to read this format; any extended attributes will be extracted as +separate files stored in +\fIPaxHeader\fP +directories. +.TP +\fBustar\fP +The libarchive library can both read and write this format. +This format has the following limitations: +.RS 5 +.IP \(bu +Device major and minor numbers are limited to 21 bits. +Nodes with larger numbers will not be added to the archive. +.IP \(bu +Path names in the archive are limited to 255 bytes. +(Shorter if there is no / character in exactly the right place.) +.IP \(bu +Symbolic links and hard links are stored in the archive with +the name of the referenced file. +This name is limited to 100 bytes. +.IP \(bu +Extended attributes, file flags, and other extended +security information cannot be stored. +.IP \(bu +Archive entries are limited to 8 gigabytes in size. +.RE +Note that the pax interchange format has none of these restrictions. +.RE +.PP +The libarchive library also reads a variety of commonly-used extensions to +the basic tar format. +These extensions are recognized automatically whenever they appear. +.RS 5 +.TP +Numeric extensions. +The POSIX standards require fixed-length numeric fields to be written with +some character position reserved for terminators. +Libarchive allows these fields to be written without terminator characters. +This extends the allowable range; in particular, ustar archives with this +extension can support entries up to 64 gigabytes in size. +Libarchive also recognizes base-256 values in most numeric fields. +This essentially removes all limitations on file size, modification time, +and device numbers. +.TP +Solaris extensions +Libarchive recognizes ACL and extended attribute records written +by Solaris tar. +Currently, libarchive only has support for old-style ACLs; the +newer NFSv4 ACLs are recognized but discarded. +.RE +.PP +The first tar program appeared in Seventh Edition Unix in 1979. +The first official standard for the tar file format was the +``ustar'' +(Unix Standard Tar) format defined by POSIX in 1988. +POSIX.1-2001 extended the ustar format to create the +``pax interchange'' +format. +.SS Cpio Formats +The libarchive library can read a number of common cpio variants and can write +``odc'' +and +``newc'' +format archives. +A cpio archive stores each entry as a fixed-size header followed +by a variable-length filename and variable-length data. +Unlike the tar format, the cpio format does only minimal padding +of the header or file data. +There are several cpio variants, which differ primarily in +how they store the initial header: some store the values as +octal or hexadecimal numbers in ASCII, others as binary values of +varying byte order and length. +.RS 5 +.TP +\fBbinary\fP +The libarchive library transparently reads both big-endian and little-endian +variants of the original binary cpio format. +This format used 32-bit binary values for file size and mtime, +and 16-bit binary values for the other fields. +.TP +\fBodc\fP +The libarchive library can both read and write this +POSIX-standard format, which is officially known as the +``cpio interchange format'' +or the +``octet-oriented cpio archive format'' +and sometimes unofficially referred to as the +``old character format''. +This format stores the header contents as octal values in ASCII. +It is standard, portable, and immune from byte-order confusion. +File sizes and mtime are limited to 33 bits (8GB file size), +other fields are limited to 18 bits. +.TP +\fBSVR4\fP +The libarchive library can read both CRC and non-CRC variants of +this format. +The SVR4 format uses eight-digit hexadecimal values for +all header fields. +This limits file size to 4GB, and also limits the mtime and +other fields to 32 bits. +The SVR4 format can optionally include a CRC of the file +contents, although libarchive does not currently verify this CRC. +.RE +.PP +Cpio first appeared in PWB/UNIX 1.0, which was released within +AT&T in 1977. +PWB/UNIX 1.0 formed the basis of System III Unix, released outside +of AT&T in 1981. +This makes cpio older than tar, although cpio was not included +in Version 7 AT&T Unix. +As a result, the tar command became much better known in universities +and research groups that used Version 7. +The combination of the +\fB\%find\fP +and +\fB\%cpio\fP +utilities provided very precise control over file selection. +Unfortunately, the format has many limitations that make it unsuitable +for widespread use. +Only the POSIX format permits files over 4GB, and its 18-bit +limit for most other fields makes it unsuitable for modern systems. +In addition, cpio formats only store numeric UID/GID values (not +usernames and group names), which can make it very difficult to correctly +transfer archives across systems with dissimilar user numbering. +.SS Shar Formats +A +``shell archive'' +is a shell script that, when executed on a POSIX-compliant +system, will recreate a collection of file system objects. +The libarchive library can write two different kinds of shar archives: +.RS 5 +.TP +\fBshar\fP +The traditional shar format uses a limited set of POSIX +commands, including +\fBecho\fP(1), +\fBmkdir\fP(1), +and +\fBsed\fP(1). +It is suitable for portably archiving small collections of plain text files. +However, it is not generally well-suited for large archives +(many implementations of +\fBsh\fP(1) +have limits on the size of a script) nor should it be used with non-text files. +.TP +\fBshardump\fP +This format is similar to shar but encodes files using +\fBuuencode\fP(1) +so that the result will be a plain text file regardless of the file contents. +It also includes additional shell commands that attempt to reproduce as +many file attributes as possible, including owner, mode, and flags. +The additional commands used to restore file attributes make +shardump archives less portable than plain shar archives. +.RE +.SS ISO9660 format +Libarchive can read and extract from files containing ISO9660-compliant +CDROM images. +In many cases, this can remove the need to burn a physical CDROM +just in order to read the files contained in an ISO9660 image. +It also avoids security and complexity issues that come with +virtual mounts and loopback devices. +Libarchive supports the most common Rockridge extensions and has partial +support for Joliet extensions. +If both extensions are present, the Joliet extensions will be +used and the Rockridge extensions will be ignored. +In particular, this can create problems with hardlinks and symlinks, +which are supported by Rockridge but not by Joliet. +.SS Zip format +Libarchive can read and write zip format archives that have +uncompressed entries and entries compressed with the +``deflate'' +algorithm. +Older zip compression algorithms are not supported. +It can extract jar archives, archives that use Zip64 extensions and many +self-extracting zip archives. +Libarchive reads Zip archives as they are being streamed, +which allows it to read archives of arbitrary size. +It currently does not use the central directory; this +limits libarchive's ability to support some self-extracting +archives and ones that have been modified in certain ways. +.SS Archive (library) file format +The Unix archive format (commonly created by the +\fBar\fP(1) +archiver) is a general-purpose format which is +used almost exclusively for object files to be +read by the link editor +\fBld\fP(1). +The ar format has never been standardised. +There are two common variants: +the GNU format derived from SVR4, +and the BSD format, which first appeared in 4.4BSD. +The two differ primarily in their handling of filenames +longer than 15 characters: +the GNU/SVR4 variant writes a filename table at the beginning of the archive; +the BSD format stores each long filename in an extension +area adjacent to the entry. +Libarchive can read both extensions, +including archives that may include both types of long filenames. +Programs using libarchive can write GNU/SVR4 format +if they provide a filename table to be written into +the archive before any of the entries. +Any entries whose names are not in the filename table +will be written using BSD-style long filenames. +This can cause problems for programs such as +GNU ld that do not support the BSD-style long filenames. +.SS mtree +Libarchive can read and write files in +\fBmtree\fP(5) +format. +This format is not a true archive format, but rather a textual description +of a file hierarchy in which each line specifies the name of a file and +provides specific metadata about that file. +Libarchive can read all of the keywords supported by both +the NetBSD and FreeBSD versions of +\fBmtree\fP(1), +although many of the keywords cannot currently be stored in an +Tn archive_entry +object. +When writing, libarchive supports use of the +\fBarchive_write_set_options\fP(3) +interface to specify which keywords should be included in the +output. +If libarchive was compiled with access to suitable +cryptographic libraries (such as the OpenSSL libraries), +it can compute hash entries such as +\fBsha512\fP +or +\fBmd5\fP +from file data being written to the mtree writer. +.PP +When reading an mtree file, libarchive will locate the corresponding +files on disk using the +\fBcontents\fP +keyword if present or the regular filename. +If it can locate and open the file on disk, it will use that +to fill in any metadata that is missing from the mtree file +and will read the file contents and return those to the program +using libarchive. +If it cannot locate and open the file on disk, libarchive +will return an error for any attempt to read the entry +body. +.SH SEE ALSO +.ad l +\fBar\fP(1), +\fBcpio\fP(1), +\fBmkisofs\fP(1), +\fBshar\fP(1),

as well as several newer implementations of +\fBtar\fP(1). +Note that the default write format will suppress the pax extended +attributes for most entries; explicitly requesting pax format will +enable those attributes for all entries. +.PP +The read and write APIs are accessed through the +\fB\%archive_read_XXX\fP() +functions and the +\fB\%archive_write_XXX\fP() +functions, respectively, and either can be used independently +of the other. +.PP +The rest of this manual page provides an overview of the library +operation. +More detailed information can be found in the individual manual +pages for each API or utility function. +.SH READING AN ARCHIVE +.ad l +To read an archive, you must first obtain an initialized +Tn struct archive +object from +\fB\%archive_read_new\fP(). +You can then modify this object for the desired operations with the +various +\fB\%archive_read_set_XXX\fP() +and +\fB\%archive_read_support_XXX\fP() +functions. +In particular, you will need to invoke appropriate +\fB\%archive_read_support_XXX\fP() +functions to enable the corresponding compression and format +support. +Note that these latter functions perform two distinct operations: +they cause the corresponding support code to be linked into your +program, and they enable the corresponding auto-detect code. +Unless you have specific constraints, you will generally want +to invoke +\fB\%archive_read_support_compression_all\fP() +and +\fB\%archive_read_support_format_all\fP() +to enable auto-detect for all formats and compression types +currently supported by the library. +.PP +Once you have prepared the +Tn struct archive +object, you call +\fB\%archive_read_open\fP() +to actually open the archive and prepare it for reading. +There are several variants of this function; +the most basic expects you to provide pointers to several +functions that can provide blocks of bytes from the archive. +There are convenience forms that allow you to +specify a filename, file descriptor, +\fIFILE *\fP +object, or a block of memory from which to read the archive data. +Note that the core library makes no assumptions about the +size of the blocks read; +callback functions are free to read whatever block size is +most appropriate for the medium. +.PP +Each archive entry consists of a header followed by a certain +amount of data. +You can obtain the next header with +\fB\%archive_read_next_header\fP(), +which returns a pointer to an +Tn struct archive_entry +structure with information about the current archive element. +If the entry is a regular file, then the header will be followed +by the file data. +You can use +\fB\%archive_read_data\fP() +(which works much like the +\fBread\fP(2) +system call) +to read this data from the archive. +You may prefer to use the higher-level +\fB\%archive_read_data_skip\fP(), +which reads and discards the data for this entry, +\fB\%archive_read_data_to_buffer\fP(), +which reads the data into an in-memory buffer, +\fB\%archive_read_data_to_file\fP(), +which copies the data to the provided file descriptor, or +\fB\%archive_read_extract\fP(), +which recreates the specified entry on disk and copies data +from the archive. +In particular, note that +\fB\%archive_read_extract\fP() +uses the +Tn struct archive_entry +structure that you provide it, which may differ from the +entry just read from the archive. +In particular, many applications will want to override the +pathname, file permissions, or ownership. +.PP +Once you have finished reading data from the archive, you +should call +\fB\%archive_read_close\fP() +to close the archive, then call +\fB\%archive_read_finish\fP() +to release all resources, including all memory allocated by the library. +.PP +The +\fBarchive_read\fP(3) +manual page provides more detailed calling information for this API. +.SH WRITING AN ARCHIVE +.ad l +You use a similar process to write an archive. +The +\fB\%archive_write_new\fP() +function creates an archive object useful for writing, +the various +\fB\%archive_write_set_XXX\fP() +functions are used to set parameters for writing the archive, and +\fB\%archive_write_open\fP() +completes the setup and opens the archive for writing. +.PP +Individual archive entries are written in a three-step +process: +You first initialize a +Tn struct archive_entry +structure with information about the new entry. +At a minimum, you should set the pathname of the +entry and provide a +\fIstruct\fP stat +with a valid +\fIst_mode\fP +field, which specifies the type of object and +\fIst_size\fP +field, which specifies the size of the data portion of the object. +The +\fB\%archive_write_header\fP() +function actually writes the header data to the archive. +You can then use +\fB\%archive_write_data\fP() +to write the actual data. +.PP +After all entries have been written, use the +\fB\%archive_write_finish\fP() +function to release all resources. +.PP +The +\fBarchive_write\fP(3) +manual page provides more detailed calling information for this API. +.SH DESCRIPTION +.ad l +Detailed descriptions of each function are provided by the +corresponding manual pages. +.PP +All of the functions utilize an opaque +Tn struct archive +datatype that provides access to the archive contents. +.PP +The +Tn struct archive_entry +structure contains a complete description of a single archive +entry. +It uses an opaque interface that is fully documented in +\fBarchive_entry\fP(3). +.PP +Users familiar with historic formats should be aware that the newer +variants have eliminated most restrictions on the length of textual fields. +Clients should not assume that filenames, link names, user names, or +group names are limited in length. +In particular, pax interchange format can easily accommodate pathnames +in arbitrary character sets that exceed +\fIPATH_MAX\fP. +.SH RETURN VALUES +.ad l +Most functions return zero on success, non-zero on error. +The return value indicates the general severity of the error, ranging +from +\fBARCHIVE_WARN\fP, +which indicates a minor problem that should probably be reported +to the user, to +\fBARCHIVE_FATAL\fP, +which indicates a serious problem that will prevent any further +operations on this archive. +On error, the +\fB\%archive_errno\fP() +function can be used to retrieve a numeric error code (see +\fBerrno\fP(2)). +The +\fB\%archive_error_string\fP() +returns a textual error message suitable for display. +.PP +\fB\%archive_read_new\fP() +and +\fB\%archive_write_new\fP() +return pointers to an allocated and initialized +Tn struct archive +object. +.PP +\fB\%archive_read_data\fP() +and +\fB\%archive_write_data\fP() +return a count of the number of bytes actually read or written. +A value of zero indicates the end of the data for this entry. +A negative value indicates an error, in which case the +\fB\%archive_errno\fP() +and +\fB\%archive_error_string\fP() +functions can be used to obtain more information. +.SH ENVIRONMENT +.ad l +There are character set conversions within the +\fBarchive_entry\fP(3) +functions that are impacted by the currently-selected locale.

provides a flexible interface for reading and writing +streaming archive files such as tar and cpio. +Internally, it follows a modular layered design that should +make it easy to add new archive and compression formats. +.SH GENERAL ARCHITECTURE +.ad l +Externally, libarchive exposes most operations through an +opaque, object-style interface. +The +\fBarchive_entry\fP(1) +objects store information about a single filesystem object. +The rest of the library provides facilities to write +\fBarchive_entry\fP(1) +objects to archive files, +read them from archive files, +and write them to disk. +(There are plans to add a facility to read +\fBarchive_entry\fP(1) +objects from disk as well.) +.PP +The read and write APIs each have four layers: a public API +layer, a format layer that understands the archive file format, +a compression layer, and an I/O layer. +The I/O layer is completely exposed to clients who can replace +it entirely with their own functions. +.PP +In order to provide as much consistency as possible for clients, +some public functions are virtualized. +Eventually, it should be possible for clients to open +an archive or disk writer, and then use a single set of +code to select and write entries, regardless of the target. +.SH READ ARCHITECTURE +.ad l +From the outside, clients use the +\fBarchive_read\fP(3) +API to manipulate an +\fB\%archive\fP +object to read entries and bodies from an archive stream. +Internally, the +\fB\%archive\fP +object is cast to an +\fB\%archive_read\fP +object, which holds all read-specific data. +The API has four layers: +The lowest layer is the I/O layer. +This layer can be overridden by clients, but most clients use +the packaged I/O callbacks provided, for example, by +\fBarchive_read_open_memory\fP(3), +and +\fBarchive_read_open_fd\fP(3). +The compression layer calls the I/O layer to +read bytes and decompresses them for the format layer. +The format layer unpacks a stream of uncompressed bytes and +creates +\fB\%archive_entry\fP +objects from the incoming data. +The API layer tracks overall state +(for example, it prevents clients from reading data before reading a header) +and invokes the format and compression layer operations +through registered function pointers. +In particular, the API layer drives the format-detection process: +When opening the archive, it reads an initial block of data +and offers it to each registered compression handler. +The one with the highest bid is initialized with the first block. +Similarly, the format handlers are polled to see which handler +is the best for each archive. +(Prior to 2.4.0, the format bidders were invoked for each +entry, but this design hindered error recovery.) +.SS I/O Layer and Client Callbacks +The read API goes to some lengths to be nice to clients. +As a result, there are few restrictions on the behavior of +the client callbacks. +.PP +The client read callback is expected to provide a block +of data on each call. +A zero-length return does indicate end of file, but otherwise +blocks may be as small as one byte or as large as the entire file. +In particular, blocks may be of different sizes. +.PP +The client skip callback returns the number of bytes actually +skipped, which may be much smaller than the skip requested. +The only requirement is that the skip not be larger. +In particular, clients are allowed to return zero for any +skip that they don't want to handle. +The skip callback must never be invoked with a negative value. +.PP +Keep in mind that not all clients are reading from disk: +clients reading from networks may provide different-sized +blocks on every request and cannot skip at all; +advanced clients may use +\fBmmap\fP(2) +to read the entire file into memory at once and return the +entire file to libarchive as a single block; +other clients may begin asynchronous I/O operations for the +next block on each request. +.SS Decompresssion Layer +The decompression layer not only handles decompression, +it also buffers data so that the format handlers see a +much nicer I/O model. +The decompression API is a two stage peek/consume model. +A read_ahead request specifies a minimum read amount; +the decompression layer must provide a pointer to at least +that much data. +If more data is immediately available, it should return more: +the format layer handles bulk data reads by asking for a minimum +of one byte and then copying as much data as is available. +.PP +A subsequent call to the +\fB\%consume\fP() +function advances the read pointer. +Note that data returned from a +\fB\%read_ahead\fP() +call is guaranteed to remain in place until +the next call to +\fB\%read_ahead\fP(). +Intervening calls to +\fB\%consume\fP() +should not cause the data to move. +.PP +Skip requests must always be handled exactly. +Decompression handlers that cannot seek forward should +not register a skip handler; +the API layer fills in a generic skip handler that reads and discards data. +.PP +A decompression handler has a specific lifecycle: +.RS 5 +.TP +Registration/Configuration +When the client invokes the public support function, +the decompression handler invokes the internal +\fB\%__archive_read_register_compression\fP() +function to provide bid and initialization functions. +This function returns +\fBNULL\fP +on error or else a pointer to a +\fBstruct\fP decompressor_t. +This structure contains a +\fIvoid\fP * config +slot that can be used for storing any customization information. +.TP +Bid +The bid function is invoked with a pointer and size of a block of data. +The decompressor can access its config data +through the +\fIdecompressor\fP +element of the +\fBarchive_read\fP +object. +The bid function is otherwise stateless. +In particular, it must not perform any I/O operations. +.PP +The value returned by the bid function indicates its suitability +for handling this data stream. +A bid of zero will ensure that this decompressor is never invoked. +Return zero if magic number checks fail. +Otherwise, your initial implementation should return the number of bits +actually checked. +For example, if you verify two full bytes and three bits of another +byte, bid 19. +Note that the initial block may be very short; +be careful to only inspect the data you are given. +(The current decompressors require two bytes for correct bidding.) +.TP +Initialize +The winning bidder will have its init function called. +This function should initialize the remaining slots of the +\fIstruct\fP decompressor_t +object pointed to by the +\fIdecompressor\fP +element of the +\fIarchive_read\fP +object. +In particular, it should allocate any working data it needs +in the +\fIdata\fP +slot of that structure. +The init function is called with the block of data that +was used for tasting. +At this point, the decompressor is responsible for all I/O +requests to the client callbacks. +The decompressor is free to read more data as and when +necessary. +.TP +Satisfy I/O requests +The format handler will invoke the +\fIread_ahead\fP, +\fIconsume\fP, +and +\fIskip\fP +functions as needed. +.TP +Finish +The finish method is called only once when the archive is closed. +It should release anything stored in the +\fIdata\fP +and +\fIconfig\fP +slots of the +\fIdecompressor\fP +object. +It should not invoke the client close callback. +.RE +.SS Format Layer +The read formats have a similar lifecycle to the decompression handlers: +.RS 5 +.TP +Registration +Allocate your private data and initialize your pointers. +.TP +Bid +Formats bid by invoking the +\fB\%read_ahead\fP() +decompression method but not calling the +\fB\%consume\fP() +method. +This allows each bidder to look ahead in the input stream. +Bidders should not look further ahead than necessary, as long +look aheads put pressure on the decompression layer to buffer +lots of data. +Most formats only require a few hundred bytes of look ahead; +look aheads of a few kilobytes are reasonable. +(The ISO9660 reader sometimes looks ahead by 48k, which +should be considered an upper limit.) +.TP +Read header +The header read is usually the most complex part of any format. +There are a few strategies worth mentioning: +For formats such as tar or cpio, reading and parsing the header is +straightforward since headers alternate with data. +For formats that store all header data at the beginning of the file, +the first header read request may have to read all headers into +memory and store that data, sorted by the location of the file +data. +Subsequent header read requests will skip forward to the +beginning of the file data and return the corresponding header. +.TP +Read Data +The read data interface supports sparse files; this requires that +each call return a block of data specifying the file offset and +size. +This may require you to carefully track the location so that you +can return accurate file offsets for each read. +Remember that the decompressor will return as much data as it has. +Generally, you will want to request one byte, +examine the return value to see how much data is available, and +possibly trim that to the amount you can use. +You should invoke consume for each block just before you return it. +.TP +Skip All Data +The skip data call should skip over all file data and trailing padding. +This is called automatically by the API layer just before each +header read. +It is also called in response to the client calling the public +\fB\%data_skip\fP() +function. +.TP +Cleanup +On cleanup, the format should release all of its allocated memory. +.RE +.SS API Layer +XXX to do XXX +.SH WRITE ARCHITECTURE +.ad l +The write API has a similar set of four layers: +an API layer, a format layer, a compression layer, and an

associated with, +slots for storing error information, +and function pointers for virtualized API functions. +.SH MISCELLANEOUS NOTES +.ad l +Connecting existing archiving libraries into libarchive is generally +quite difficult. +In particular, many existing libraries strongly assume that you +are reading from a file; they seek forwards and backwards as necessary +to locate various pieces of information. +In contrast, libarchive never seeks backwards in its input, which +sometimes requires very different approaches. +.PP +For example, libarchive's ISO9660 support operates very differently +from most ISO9660 readers. +The libarchive support utilizes a work-queue design that +keeps a list of known entries sorted by their location in the input. +Whenever libarchive's ISO9660 implementation is asked for the next +header, checks this list to find the next item on the disk. +Directories are parsed when they are encountered and new +items are added to the list. +This design relies heavily on the ISO9660 image being optimized so that +directories always occur earlier on the disk than the files they +describe. +.PP +Depending on the specific format, such approaches may not be possible. +The ZIP format specification, for example, allows archivers to store +key information only at the end of the file. +In theory, it is possible to create ZIP archives that cannot +be read without seeking. +Fortunately, such archives are very rare, and libarchive can read +most ZIP archives, though it cannot always extract as much information +as a dedicated ZIP program. +.SH SEE ALSO

+The +\fB\%tar\fP +archive format collects any number of files, directories, and other +file system objects (symbolic links, device nodes, etc.) into a single +stream of bytes. +The format was originally designed to be used with +tape drives that operate with fixed-size blocks, but is widely used as +a general packaging mechanism. +.SS General Format +A +\fB\%tar\fP +archive consists of a series of 512-byte records. +Each file system object requires a header record which stores basic metadata +(pathname, owner, permissions, etc.) and zero or more records containing any +file data. +The end of the archive is indicated by two records consisting +entirely of zero bytes. +.PP +For compatibility with tape drives that use fixed block sizes, +programs that read or write tar files always read or write a fixed +number of records with each I/O operation. +These +``blocks'' +are always a multiple of the record size. +The maximum block size supported by early +implementations was 10240 bytes or 20 records. +This is still the default for most implementations +although block sizes of 1MiB (2048 records) or larger are +commonly used with modern high-speed tape drives. +(Note: the terms +``block'' +and +``record'' +here are not entirely standard; this document follows the +convention established by John Gilmore in documenting +\fB\%pdtar\fP.) +.SS Old-Style Archive Format +The original tar archive format has been extended many times to +include additional information that various implementors found +necessary. +This section describes the variant implemented by the tar command +included in +At v7, +which seems to be the earliest widely-used version of the tar program. +.PP +The header record for an old-style +\fB\%tar\fP +archive consists of the following: +.RS 4

files (including +hardlinks to those files). +One common early convention used a trailing "/" character to indicate +a directory name, allowing directory permissions and owner information +to be archived and restored. +.TP +\fImode\fP +File mode, stored as an octal number in ASCII. +.TP +\fIuid\fP, \fIgid\fP +User id and group id of owner, as octal numbers in ASCII. +.TP +\fIsize\fP +Size of file, as octal number in ASCII. +For regular files only, this indicates the amount of data +that follows the header. +In particular, this field was ignored by early tar implementations +when extracting hardlinks. +Modern writers should always store a zero length for hardlink entries. +.TP +\fImtime\fP +Modification time of file, as an octal number in ASCII. +This indicates the number of

stored as an octal number in ASCII. +To compute the checksum, set the checksum field to all spaces, +then sum all bytes in the header using unsigned arithmetic. +This field should be stored as six octal digits followed by a null and a space +character. +Note that many early implementations of tar used signed arithmetic +for the checksum field, which can cause interoperability problems +when transferring archives between systems. +Modern robust readers compute the checksum both ways and accept the +header if either computation matches. +.TP +\fIlinkflag\fP, \fIlinkname\fP +In order to

implementations varied in how they terminated these fields. +The tar command in +At v7 +used the following conventions (this is also documented in early BSD manpages): +the pathname must be null-terminated; +the mode, uid, and gid fields must end in a space and a null byte; +the size and mtime fields must end in a space; +the checksum is terminated by a null and a space. +Early implementations filled the numeric fields with leading spaces. +This seems to have been common practice until the +IEEE Std 1003.1-1988 (``POSIX.1'') +standard was released. +For best portability, modern implementations should fill the numeric +fields with leading zeros. +.SS Pre-POSIX Archives +An early draft of +IEEE Std 1003.1-1988 (``POSIX.1'') +served as the basis for John Gilmore's

decimal number, a space, a key string, an equals +sign, a value string, and a new line. +The decimal number indicates the length of the entire line, including the +initial length field and the trailing newline. +An example of such a field is: +.RS 4 +25 ctime=1084839148.1212\en +.RE +Keys in all lowercase are standard keys. +Vendors can add their own keys by prefixing them with an all

+it allowed the header to be continued over multiple records; +and it defined new entries that modify following entries +(similar in principle to the +\fBx\fP +entry described above, but each GNU special entry is single-purpose, +unlike the general-purpose +\fBx\fP +entry). +As a result, GNU tar archives are not POSIX compatible, although +more lenient POSIX-compliant readers can successfully extract most +GNU tar archives. +.RS 4 +.nf +struct header_gnu_tar { + char name[100];

DESCRIPTION +These functions create and manipulate data objects that +represent entries within an archive. +You can think of a +.Tn struct archive_entry +as a heavy-duty version of +.Tn struct stat : +it includes everything from +.Tn struct stat +plus associated pathname, textual group and user names, etc. +These objects are used by +.Xr libarchive 3 +to represent the metadata associated with a particular +entry in an archive. +.Ss Create and Destroy +There are functions to allocate, destroy, clear, and copy +.Va archive_entry +objects: +.Bl -tag -compact -width indent +.It Fn archive_entry_clear +Erases the object, resetting all internal fields to the +same state as a newly-created object. +This is provided to allow you to quickly recycle objects +without thrashing the heap. +.It Fn archive_entry_clone +A deep copy operation; all text fields are duplicated. +.It Fn archive_entry_free +Releases the +.Tn struct archive_entry +object. +.It Fn archive_entry_new +Allocate and return a blank +.Tn struct archive_entry +object. +.El +.Ss Set and Get Functions +Most of the functions here set or read entries in an object. +Such functions have one of the following forms: +.Bl -tag -compact -width indent +.It Fn archive_entry_set_XXXX +Stores the provided data in the object. +In particular, for strings, the pointer is stored, +not the referenced string. +.It Fn archive_entry_copy_XXXX +As above, except that the referenced data is copied +into the object. +.It Fn archive_entry_XXXX +Returns the specified data. +In the case of strings, a const-qualified pointer to +the string is returned. +.El +String data can be set or accessed as wide character strings +or normal +.Va char +strings. +The functions that use wide character strings are suffixed with +.Cm _w . +Note that these are different representations of the same data: +For example, if you store a narrow string and read the corresponding +wide string, the object will transparently convert formats +using the current locale. +Similarly, if you store a wide string and then store a +narrow string for the same data, the previously-set wide string will +be discarded in favor of the new data. +.Pp +There are a few set/get functions that merit additional description: +.Bl -tag -compact -width indent +.It Fn archive_entry_set_link +This function sets the symlink field if it is already set. +Otherwise, it sets the hardlink field. +.El +.Ss File Flags +File flags are transparently converted between a bitmap +representation and a textual format. +For example, if you set the bitmap and ask for text, the library +will build a canonical text format. +However, if you set a text format and request a text format, +you will get back the same text, even if it is ill-formed. +If you need to canonicalize a textual flags string, you should first set the +text form, then request the bitmap form, then use that to set the bitmap form. +Setting the bitmap format will clear the internal text representation +and force it to be reconstructed when you next request the text form. +.Pp +The bitmap format consists of two integers, one containing bits +that should be set, the other specifying bits that should be +cleared. +Bits not mentioned in either bitmap will be ignored. +Usually, the bitmap of bits to be cleared will be set to zero. +In unusual circumstances, you can force a fully-specified set +of file flags by setting the bitmap of flags to clear to the complement +of the bitmap of flags to set. +(This differs from +.Xr fflagstostr 3 , +which only includes names for set bits.) +Converting a bitmap to a textual string is a platform-specific +operation; bits that are not meaningful on the current platform +will be ignored. +.Pp +The canonical text format is a comma-separated list of flag names. +The +.Fn archive_entry_copy_fflags_text +and +.Fn archive_entry_copy_fflags_text_w +functions parse the provided text and sets the internal bitmap values. +This is a platform-specific operation; names that are not meaningful +on the current platform will be ignored. +The function returns a pointer to the start of the first name that was not +recognized, or NULL if every name was recognized. +Note that every name--including names that follow an unrecognized name--will +be evaluated, and the bitmaps will be set to reflect every name that is +recognized. +(In particular, this differs from +.Xr strtofflags 3 , +which stops parsing at the first unrecognized name.) +.Ss ACL Handling +XXX This needs serious help. +XXX +.Pp +An +.Dq Access Control List +(ACL) is a list of permissions that grant access to particular users or +groups beyond what would normally be provided by standard POSIX mode bits. +The ACL handling here addresses some deficiencies in the POSIX.1e draft 17 ACL +specification. +In particular, POSIX.1e draft 17 specifies several different formats, but +none of those formats include both textual user/group names and numeric +UIDs/GIDs. +.Pp +XXX explain ACL stuff XXX +.\" .Sh EXAMPLE +.\" .Sh RETURN VALUES +.\" .Sh ERRORS +.Sh SEE ALSO +.Xr archive 3 +.Sh HISTORY +The +.Nm libarchive +library first appeared in +.Fx 5.3 . +.Sh

Old cpio archives + * store every link with the full body; the onus is on the dearchiver + * to detect and properly link the files as they are restored. + * "tar" is also pretty simple; it caches a copy the first time it sees + * any link. Subsequent appearances are modified to be hardlink + * references to the first one without any body. Used by all tar + * formats, although the newest tar formats permit the "old cpio" strategy + * as well. This strategy is very simple for the dearchiver, + * and reasonably straightforward for the archiver. + * "new cpio" is trickier. It stores the body only with the last + * occurrence. The complication is that we might not + * see every link to a particular file in a single session, so + * there's no easy way to know when we've seen the last occurrence. + * The solution here is to queue one link until we see the next. + * At the end of the session, you can enumerate any remaining + * entries by calling archive_entry_linkify(NULL) and store those + * bodies. If you have a file with three links l1, l2, and l3, + * you'll get the following behavior if you see all three links: + * linkify(l1) => NULL (the resolver stores l1 internally) + * linkify(l2) => l1 (resolver stores l2, you write l1) + * linkify(l3) => l2, l3 (all links seen, you can write both). + * If you only see l1 and l2, you'll get this behavior: + * linkify(l1) => NULL + * linkify(l2) => l1 + * linkify(NULL) => l2 (at end, you retrieve remaining links) + * As the name suggests, this strategy is used by newer cpio variants. + * It's noticably more complex for the archiver, slightly more complex + * for the dearchiver than the tar strategy, but makes it straightforward + * to restore a file using any link by simply continuing to scan until + * you see a link that is stored with a body. In contrast, the tar + * strategy requires you to rescan the archive from the beginning to + * correctly extract an arbitrary link. + */ + +__LA_DECL struct archive_entry_linkresolver *archive_entry_linkresolver_new(void); +__LA_DECL void archive_entry_linkresolver_set_strategy( + struct archive_entry_linkresolver *, int /* format_code */); +__LA_DECL void archive_entry_linkresolver_free(struct archive_entry_linkresolver *); +__LA_DECL void archive_entry_linkify(struct archive_entry_linkresolver *, + struct archive_entry **, struct archive_entry **); + +#ifdef __cplusplus +} +#endif + +/* This is meaningless outside of this header. */ +#undef __LA_DECL + +#endif /* !ARCHIVE_ENTRY_H_INCLUDED */ diff --git a/archivers/libarchive/files/libarchive/archive_entry_copy_stat.c b/archivers/libarchive/files/libarchive/archive_entry_copy_stat.c new file mode 100644 index 00000000000..ef59a5e78a0 --- /dev/null +++ b/archivers/libarchive/files/libarchive/archive_entry_copy_stat.c @@ -0,0 +1,77 @@ +/*- + * Copyright (c) 2003-2007 Tim Kientzle + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

set options, initialize the reader, iterate over the archive +headers and associated data, then close the archive and release all +resources. +The following summary describes the functions in approximately the +order they would be used: +.Bl -tag -compact -width indent +.It Fn archive_read_new +Allocates and initializes a +.Tn struct archive +object suitable for reading from an archive. +.It Xo +.Fn archive_read_support_compression_bzip2 , +.Fn archive_read_support_compression_compress , +.Fn archive_read_support_compression_gzip , +.Fn archive_read_support_compression_lzma , +.Fn archive_read_support_compression_none , +.Fn archive_read_support_compression_xz +.Xc +Enables auto-detection code and decompression support for the +specified compression. +Returns +.Cm ARCHIVE_OK +if the compression is fully supported, or +.Cm ARCHIVE_WARN +if the compression is supported only through an external program. +Note that decompression using an external program is usually slower than +decompression through built-in libraries. +Note that +.Dq none +is always enabled by default. +.It Fn archive_read_support_compression_all +Enables all available decompression filters. +.It Fn archive_read_support_compression_program +Data is fed through the specified external program before being dearchived. +Note that this disables automatic detection of the compression format, +so it makes no sense to specify this in conjunction with any other +decompression option. +.It Fn archive_read_support_compression_program_signature +This feeds data through the specified external program +but only if the initial bytes of the data match the specified +signature value. +.It Xo +.Fn archive_read_support_format_all , +.Fn archive_read_support_format_ar , +.Fn archive_read_support_format_cpio , +.Fn archive_read_support_format_empty , +.Fn archive_read_support_format_iso9660 , +.Fn archive_read_support_format_mtree , +.Fn archive_read_support_format_tar , +.Fn archive_read_support_format_zip +.Xc +Enables support---including auto-detection code---for the +specified archive format. +For example, +.Fn archive_read_support_format_tar +enables support for a variety of standard tar formats, old-style tar, +ustar, pax interchange format, and many common variants. +For convenience, +.Fn archive_read_support_format_all +enables support for all available formats. +Only empty archives are supported by default. +.It Fn archive_read_support_format_raw +The +.Dq raw +format handler allows libarchive to be used to read arbitrary data. +It treats any data stream as an archive with a single entry. +The pathname of this entry is +.Dq data ; +all other entry fields are unset. +This is not enabled by +.Fn archive_read_support_format_all +in order to avoid erroneous handling of damaged archives. +.It Xo +.Fn archive_read_set_filter_options , +.Fn archive_read_set_format_options , +.Fn archive_read_set_options +.Xc +Specifies options that will be passed to currently-registered +filters (including decompression filters) and/or format readers. +The argument is a comma-separated list of individual options. +Individual options have one of the following forms: +.Bl -tag -compact -width indent +.It Ar option=value +The option/value pair will be provided to every module. +Modules that do not accept an option with this name will ignore it. +.It Ar option +The option will be provided to every module with a value of +.Dq 1 . +.It Ar !option +The option will be provided to every module with a NULL value. +.It Ar module:option=value , Ar module:option , Ar module:!option +As above, but the corresponding option and value will be provided +only to modules whose name matches +.Ar module . +.El +The return value will be +.Cm ARCHIVE_OK +if any module accepts the option, or +.Cm ARCHIVE_WARN +if no module accepted the option, or +.Cm ARCHIVE_FATAL +if there was a fatal error while attempting to process the option. +.Pp +The currently supported options are: +.Bl -tag -compact -width indent +.It Format iso9660 +.Bl -tag -compact -width indent +.It Cm joliet +Support Joliet extensions. +Defaults to enabled, use +.Cm !joliet +to disable. +.El +.El +.It Fn archive_read_open +The same as +.Fn archive_read_open2 , +except that the skip callback is assumed to be +.Dv NULL . +.It Fn archive_read_open2 +Freeze the settings, open the archive, and prepare for reading entries. +This is the most generic version of this call, which accepts +four callback functions. +Most clients will want to use +.Fn archive_read_open_filename , +.Fn archive_read_open_FILE , +.Fn archive_read_open_fd , +or +.Fn archive_read_open_memory +instead. +The library invokes the client-provided functions to obtain +raw bytes from the archive. +.It Fn archive_read_open_FILE +Like +.Fn archive_read_open , +except that it accepts a +.Ft "FILE *" +pointer. +This function should not be used with tape drives or other devices +that require strict I/O blocking. +.It Fn archive_read_open_fd +Like +.Fn archive_read_open , +except that it accepts a file descriptor and block size rather than +a set of function pointers. +Note that the file descriptor will not be automatically closed at +end-of-archive. +This function is safe for use with tape drives or other blocked devices. +.It Fn archive_read_open_file +This is a deprecated synonym for +.Fn archive_read_open_filename . +.It Fn archive_read_open_filename +Like +.Fn archive_read_open , +except that it accepts a simple filename and a block size. +A NULL filename represents standard input. +This function is safe for use with tape drives or other blocked devices. +.It Fn archive_read_open_memory +Like +.Fn archive_read_open , +except that it accepts a pointer and size of a block of +memory containing the archive data. +.It Fn archive_read_next_header +Read the header for the next entry and return a pointer to +a +.Tn struct archive_entry . +This is a convenience wrapper around +.Fn archive_read_next_header2 +that reuses an internal +.Tn struct archive_entry +object for each request. +.It Fn archive_read_next_header2 +Read the header for the next entry and populate the provided +.Tn struct archive_entry . +.It Fn archive_read_data +Read data associated with the header just read. +Internally, this is a convenience function that calls +.Fn archive_read_data_block +and fills any gaps with nulls so that callers see a single +continuous stream of data. +.It Fn archive_read_data_block +Return the next available block of data for this entry. +Unlike +.Fn archive_read_data , +the +.Fn archive_read_data_block +function avoids copying data and allows you to correctly handle +sparse files, as supported by some archive formats. +The library guarantees that offsets will increase and that blocks +will not overlap. +Note that the blocks returned from this function can be much larger +than the block size read from disk, due to compression +and internal buffer optimizations. +.It Fn archive_read_data_skip +A convenience function that repeatedly calls +.Fn archive_read_data_block +to skip all of the data for this archive entry. +.\" #if ARCHIVE_API_VERSION < 3 +.It Fn archive_read_data_into_buffer +This function is deprecated and will be removed. +Use +.Fn archive_read_data +instead. +.\" #endif +.It Fn archive_read_data_into_fd +A convenience function that repeatedly calls +.Fn archive_read_data_block +to copy the entire entry to the provided file descriptor. +.It Fn archive_read_extract , Fn archive_read_extract_set_skip_file +A convenience function that wraps the corresponding +.Xr archive_write_disk 3 +interfaces. +The first call to +.Fn archive_read_extract +creates a restore object using +.Xr archive_write_disk_new 3 +and +.Xr archive_write_disk_set_standard_lookup 3 , +then transparently invokes +.Xr archive_write_disk_set_options 3 , +.Xr archive_write_header 3 , +.Xr archive_write_data 3 , +and +.Xr archive_write_finish_entry 3 +to create the entry on disk and copy data into it. +The +.Va flags +argument is passed unmodified to +.Xr archive_write_disk_set_options 3 . +.It Fn archive_read_extract2 +This is another version of +.Fn archive_read_extract +that allows you to provide your own restore object. +In particular, this allows you to override the standard lookup functions +using +.Xr archive_write_disk_set_group_lookup 3 , +and +.Xr archive_write_disk_set_user_lookup 3 . +Note that +.Fn archive_read_extract2 +does not accept a +.Va flags +argument; you should use +.Fn archive_write_disk_set_options +to set the restore options yourself. +.It Fn archive_read_extract_set_progress_callback +Sets a pointer to a user-defined callback that can be used +for updating progress displays during extraction. +The progress function will be invoked during the extraction of large +regular files. +The progress function will be invoked with the pointer provided to this call. +Generally, the data pointed to should include a reference to the archive +object and the archive_entry object so that various statistics +can be retrieved for the progress display. +.It Fn archive_read_close +Complete the archive and invoke the close callback. +.It Fn archive_read_finish +Invokes +.Fn archive_read_close +if it was not invoked manually, then release all resources. +Note: In libarchive 1.x, this function was declared to return +.Ft void , +which made it impossible to detect certain errors when +.Fn archive_read_close +was invoked implicitly from this function. +The declaration is corrected beginning with libarchive 2.0. +.El +.Pp +Note that the library determines most of the relevant information about +the archive by inspection. +In particular, it automatically detects +.Xr gzip 1 +or +.Xr bzip2 1 +compression and transparently performs the appropriate decompression. +It also automatically detects the archive format. +.Pp +A complete description of the +.Tn struct archive +and +.Tn struct archive_entry +objects can be found in the overview manual page for +.Xr libarchive 3 . +.Sh CLIENT CALLBACKS +The callback functions must match the following

*client_data" +.It +.Ft typedef int +.Fn archive_close_callback "struct archive *" "void *client_data" +.El +.Pp +The open callback is invoked by +.Fn archive_open . +It should return +.Cm ARCHIVE_OK +if the underlying file or data source is successfully +opened. +If the open fails, it should call +.Fn archive_set_error +to register an error code and message and return +.Cm ARCHIVE_FATAL . +.Pp +The read callback is invoked whenever the library +requires raw bytes from the archive. +The read callback should read data into a buffer, +set the +.Li const void **buffer +argument to point to the available data, and +return a count of the number of bytes available. +The library will invoke the read callback again +only after it has consumed this data. +The library imposes no constraints on the size +of the data blocks returned. +On end-of-file, the read callback should +return zero. +On error, the read callback should invoke +.Fn archive_set_error +to register an error code and message and +return -1. +.Pp +The skip callback is invoked when the +library wants to ignore a block of data. +The return value is the number of bytes actually +skipped, which may differ from the request. +If the callback cannot skip data, it should return +zero. +If the skip callback is not provided (the +function pointer is +.Dv NULL ), +the library will invoke the read function +instead and simply discard the result. +A skip callback can provide significant +performance gains when reading uncompressed +archives from slow disk drives or other media +that can skip quickly. +.Pp +The close callback is invoked by archive_close when +the archive processing is complete. +The callback should return +.Cm ARCHIVE_OK +on success. +On failure, the callback should invoke +.Fn archive_set_error +to register an error code and message and +return +.Cm ARCHIVE_FATAL. +.Sh EXAMPLE +The following illustrates basic usage of the library. +In this example, +the callback functions are simply wrappers around the standard +.Xr open 2 , +.Xr read 2 , +and +.Xr close 2 +system calls. +.Bd -literal -offset indent +void +list_archive(const char *name) +{ + struct mydata *mydata; + struct archive *a; + struct

general process is to first create the +.Tn struct archive +object, set any desired options, initialize the archive, append entries, then +close the archive and release all resources. +The following summary describes the functions in approximately +the order they are ordinarily used: +.Bl -tag -width indent +.It Fn archive_write_new +Allocates and initializes a +.Tn struct archive +object suitable for writing a tar archive. +.It Fn archive_write_set_bytes_per_block +Sets the block size used for writing the archive data. +Every call to the write callback function, except possibly the last one, will +use this value for the length. +The third parameter is a boolean that specifies whether or not the final block +written will be padded to the full block size. +If it is zero, the last block will not be padded. +If it is non-zero, padding will be added both before and after compression. +The default is to use a block size of 10240 bytes and to pad the last block. +Note that a block size of zero will suppress internal blocking +and cause writes to be sent directly to the write callback as they occur. +.It Fn archive_write_get_bytes_per_block +Retrieve the block size to be used for writing. +A value of -1 here indicates that the library should use default values. +A value of zero indicates that internal blocking is suppressed. +.It Fn archive_write_set_bytes_in_last_block +Sets the block size used for writing the last block. +If this value is zero, the last block will be padded to the same size +as the other blocks. +Otherwise, the final block will be padded to a multiple of this size. +In particular, setting it to 1 will cause the final block to not be padded. +For compressed output, any padding generated by this option +is applied only after the compression. +The uncompressed data is always unpadded. +The default is to pad the last block to the full block size (note that +.Fn archive_write_open_filename +will set this based on the file type). +Unlike the other +.Dq set +functions, this function can be called after the archive is opened. +.It Fn archive_write_get_bytes_in_last_block +Retrieve the currently-set value for last block size. +A value of -1 here indicates that the library should use default values. +.It Xo +.Fn archive_write_set_format_cpio , +.Fn archive_write_set_format_pax , +.Fn archive_write_set_format_pax_restricted , +.Fn archive_write_set_format_shar , +.Fn archive_write_set_format_shar_binary , +.Fn archive_write_set_format_ustar +.Xc +Sets the format that will be used for the archive. +The library can write +POSIX octet-oriented cpio format archives, +POSIX-standard +.Dq pax interchange +format archives, +traditional +.Dq shar +archives, +enhanced +.Dq binary +shar archives that store a variety of file attributes and handle binary files, +and +POSIX-standard +.Dq ustar +archives. +The pax interchange format is a backwards-compatible tar format that +adds key/value attributes to each entry and supports arbitrary +filenames, linknames, uids, sizes, etc. +.Dq Restricted pax interchange format +is the library default; this is the same as pax format, but suppresses +the pax extended header for most normal files. +In most cases, this will result in ordinary ustar archives. +.It Xo +.Fn archive_write_set_compression_bzip2 , +.Fn archive_write_set_compression_compress , +.Fn archive_write_set_compression_gzip , +.Fn archive_write_set_compression_none +.Xc +The resulting archive will be compressed as specified. +Note that the compressed output is always properly blocked. +.It Fn archive_write_set_compression_program +The archive will be fed into the specified compression program. +The output of that program is blocked and written to the client +write callbacks. +.It Xo +.Fn archive_write_set_compressor_options , +.Fn archive_write_set_format_options , +.Fn archive_write_set_options +.Xc +Specifies options that will be passed to the currently-enabled +compressor and/or format writer. +The argument is a comma-separated list of individual options. +Individual options have one of the following forms: +.Bl -tag -compact -width indent +.It Ar option=value +The

correct blocking. +.It Fn archive_write_open_file +A deprecated synonym for +.Fn archive_write_open_filename . +.It Fn archive_write_open_filename +A convenience form of +.Fn archive_write_open +that accepts a filename. +A NULL argument indicates that the output should be written to standard output; +an argument of +.Dq - +will open a file with that name. +If you have not invoked +.Fn archive_write_set_bytes_in_last_block , +then +.Fn archive_write_open_filename +will adjust the last-block padding depending on the file: +it will enable padding when writing to standard output or +to a character or block device node, it will disable padding otherwise. +You can override this by manually invoking +.Fn archive_write_set_bytes_in_last_block +before calling +.Fn archive_write_open . +The +.Fn archive_write_open_filename +function is safe for use with tape drives or other +block-oriented devices. +.It Fn archive_write_open_memory +A convenience form of +.Fn archive_write_open +that accepts a pointer to a block of memory that will receive +the archive. +The final +.Ft "size_t *" +argument points to a variable that will be updated +after each write to reflect how much of the buffer +is currently in use. +You should be careful to ensure that this variable +remains allocated until after the archive is +closed. +.It Fn archive_write_header +Build and write a header using the data in the provided +.Tn struct archive_entry +structure. +See +.Xr archive_entry 3 +for information on creating and populating +.Tn struct archive_entry +objects. +.It Fn archive_write_data +Write data corresponding to the header just written. +Returns number of bytes written or -1 on error. +.It Fn archive_write_finish_entry +Close out the entry just written. +In particular, this writes out the final padding required by some formats. +Ordinarily, clients never need to call this, as it +is called automatically by +.Fn archive_write_next_header +and +.Fn archive_write_close +as needed. +.It Fn archive_write_close +Complete the archive and invoke the close callback. +.It Fn archive_write_finish +Invokes +.Fn archive_write_close +if it was not invoked manually, then releases all resources. +Note that this function was declared to return +.Ft void +in libarchive 1.x, which made it impossible to detect errors when +.Fn archive_write_close +was invoked implicitly from this function. +This is corrected beginning with libarchive 2.0. +.El +More information about the +.Va struct archive +object and the overall design of the library can be found in the +.Xr libarchive 3 +overview. +.Sh IMPLEMENTATION +Compression support is built-in to libarchive, which uses zlib and bzlib +to handle gzip and bzip2 compression, respectively. +.Sh CLIENT CALLBACKS +To use this library, you will need to define and register +callback functions that will be invoked to write data to the +resulting archive. +These functions are registered by calling +.Fn archive_write_open : +.Bl -item -offset indent +.It +.Ft typedef int +.Fn archive_open_callback "struct archive *" "void *client_data" +.El +.Pp +The open callback is invoked by +.Fn archive_write_open . +It should return +.Cm ARCHIVE_OK +if the underlying file or data source is successfully +opened. +If the open fails, it should call +.Fn archive_set_error +to register an error code and message and return +.Cm ARCHIVE_FATAL . +.Bl -item -offset indent +.It +.Ft typedef ssize_t +.Fo archive_write_callback +.Fa "struct archive *" +.Fa "void *client_data" +.Fa "const void *buffer" +.Fa "size_t length" +.Fc +.El +.Pp +The write callback is invoked whenever the library +needs to write raw bytes to the archive. +For correct blocking, each call to the write callback function +should translate into a single +.Xr write 2 +system call. +This is especially critical when writing archives to tape drives. +On success, the write callback should return the +number of bytes actually written. +On error, the callback should invoke +.Fn archive_set_error +to register an error code and message and return -1. +.Bl -item -offset indent +.It +.Ft typedef int +.Fn archive_close_callback "struct archive *" "void *client_data" +.El +.Pp +The close callback is invoked by archive_close when +the archive processing is complete. +The callback should return +.Cm ARCHIVE_OK +on success. +On failure, the callback should invoke +.Fn archive_set_error +to register an error code and message and +return +.Cm ARCHIVE_FATAL. +.Sh EXAMPLE +The following sketch illustrates basic usage of the library. +In this example, +the callback functions are simply wrappers around the standard +.Xr open 2 , +.Xr write 2 , +and +.Xr close 2 +system calls. +.Bd -literal -offset indent +#ifdef __linux__ +#define _FILE_OFFSET_BITS

appeared in +.Fx 5.3 . +.Sh AUTHORS +.An -nosplit +The +.Nm libarchive +library was written by +.An Tim Kientzle Aq kientzle@acm.org . +.Sh BUGS +There are many peculiar bugs in historic tar implementations that may cause +certain programs to reject archives written by this library. +For example, several historic implementations calculated header checksums +incorrectly and will thus reject valid archives; GNU tar does not fully support +pax interchange format; some old tar implementations required specific +field terminations. +.Pp +The default pax interchange format eliminates most of the historic +tar limitations and provides a generic key/value attribute facility +for vendor-defined extensions. +One oversight in POSIX is the failure to provide a standard attribute +for large device numbers. +This library uses +.Dq SCHILY.devminor +and +.Dq SCHILY.devmajor +for device numbers that exceed the range supported by the backwards-compatible +ustar header. +These keys are compatible with Joerg Schilling's +.Nm star +archiver. +Other implementations may not recognize these keys and will thus be unable +to correctly restore device nodes with large device numbers from archives +created by this library. diff --git a/archivers/libarchive/files/libarchive/archive_write.c b/archivers/libarchive/files/libarchive/archive_write.c new file mode 100644 index

archive_write_finish "struct archive *" +.Sh DESCRIPTION +These functions provide a complete API for creating objects on +disk from +.Tn struct archive_entry +descriptions. +They are most naturally used when extracting objects from an archive +using the +.Fn archive_read +interface. +The general process is to read +.Tn struct archive_entry +objects from an archive, then write those objects to a +.Tn struct archive +object created using the +.Fn archive_write_disk +family functions. +This interface is deliberately very similar to the +.Fn archive_write +interface used to write objects to a streaming archive. +.Bl -tag -width indent +.It Fn archive_write_disk_new +Allocates and initializes a +.Tn struct archive +object suitable for writing objects to disk. +.It Fn archive_write_disk_set_skip_file +Records the device and inode numbers of a file that should not be +overwritten. +This is typically used to ensure that an extraction process does not +overwrite the archive from which objects are being read. +This capability is technically unnecessary but can be a significant +performance optimization in practice. +.It Fn archive_write_disk_set_options +The options field consists of a bitwise OR of one or more of the +following values: +.Bl -tag -compact -width "indent" +.It Cm ARCHIVE_EXTRACT_OWNER +The user and group IDs should be set on the restored file. +By default, the user and group IDs are not restored. +.It Cm ARCHIVE_EXTRACT_PERM +Full permissions (including SGID, SUID, and sticky bits) should +be restored exactly as specified, without obeying the +current umask. +Note that SUID and SGID bits can only be restored if the +user and group ID of the object on disk are correct. +If +.Cm ARCHIVE_EXTRACT_OWNER +is not specified, then SUID and SGID bits will only be restored +if the default user and group IDs of newly-created objects on disk +happen to match those specified in the archive entry. +By default, only basic permissions are restored, and umask is obeyed. +.It Cm ARCHIVE_EXTRACT_TIME +The timestamps (mtime, ctime, and atime) should be restored. +By default, they are ignored. +Note that restoring of atime is not currently supported. +.It Cm ARCHIVE_EXTRACT_NO_OVERWRITE +Existing files on disk will not be overwritten. +By default, existing regular files are truncated and overwritten; +existing directories will have their permissions updated; +other pre-existing objects are unlinked and recreated from scratch. +.It Cm ARCHIVE_EXTRACT_UNLINK +Existing files on disk will be unlinked before any attempt to +create them. +In some cases, this can prove to be a significant performance improvement. +By default, existing files are truncated and rewritten, but +the file is not recreated. +In particular, the default behavior does not break existing hard links. +.It Cm ARCHIVE_EXTRACT_ACL +Attempt to restore ACLs. +By default, extended ACLs are ignored. +.It Cm ARCHIVE_EXTRACT_FFLAGS +Attempt to restore extended file flags. +By default, file flags are ignored. +.It Cm ARCHIVE_EXTRACT_XATTR +Attempt to restore POSIX.1e extended attributes. +By default, they are ignored. +.It Cm ARCHIVE_EXTRACT_SECURE_SYMLINKS +Refuse to extract any object whose final location would be altered +by a symlink on disk. +This is intended to help guard against a variety of mischief +caused by archives that (deliberately or otherwise) extract +files outside of the current directory. +The default is not to perform this check. +If +.Cm ARCHIVE_EXTRACT_UNLINK +is specified together with this option, the library will +remove any intermediate symlinks it finds and return an +error only if such symlink could not be removed. +.It Cm ARCHIVE_EXTRACT_SECURE_NODOTDOT +Refuse to extract a path that contains a +.Pa .. +element anywhere within it. +The default is to not refuse such paths. +Note that paths ending in +.Pa .. +always cause an error, regardless of this flag. +.It Cm ARCHIVE_EXTRACT_SPARSE +Scan data for blocks of NUL bytes and try to recreate them with holes. +This results in sparse files, independent of whether the archive format +supports or uses them. +.El +.It Xo +.Fn archive_write_disk_set_group_lookup , +.Fn archive_write_disk_set_user_lookup +.Xc +The +.Tn struct archive_entry +objects contain both names and ids that can be used to identify users +and groups. +These names and ids describe the ownership of the file itself and +also appear in ACL lists. +By default, the library uses the ids and ignores the names, but +this can be overridden by registering user and group lookup functions. +To register, you must provide a lookup function which +accepts both a name and id and returns a suitable id. +You may also provide a +.Tn void * +pointer to a private data structure and a cleanup function for +that data. +The cleanup function will be invoked when the +.Tn struct archive +object is destroyed. +.It Fn archive_write_disk_set_standard_lookup +This convenience function installs a standard set of user +and group lookup functions. +These functions use +.Xr getpwnam 3 +and +.Xr getgrnam 3 +to convert names to ids, defaulting to the ids if the names cannot +be looked up. +These functions also implement a simple memory cache to reduce +the number of calls to +.Xr getpwnam 3 +and +.Xr getgrnam 3 . +.It Fn archive_write_header +Build and write a header using the data in the provided +.Tn struct archive_entry +structure. +See +.Xr archive_entry 3 +for information on creating and populating +.Tn struct archive_entry +objects. +.It Fn archive_write_data +Write data corresponding to the header just written. +Returns number of bytes written or -1 on error. +.It Fn archive_write_finish_entry +Close out the entry just written. +Ordinarily, clients never need to call this, as it +is called automatically by +.Fn archive_write_next_header +and +.Fn archive_write_close +as needed. +.It Fn archive_write_close +Set any attributes that could not be set during the initial restore. +For example, directory timestamps are not restored initially because +restoring a subsequent file would alter that timestamp. +Similarly, non-writable directories are initially created with +write permissions (so that their contents can be restored). +The +.Nm +library maintains a list of all such deferred attributes and +sets them when this function is invoked. +.It Fn archive_write_finish +Invokes +.Fn archive_write_close +if it was not invoked manually, then releases all resources. +.El +More information about the +.Va struct archive +object and the overall design of the library can be found in the +.Xr libarchive 3 +overview. +Many of these functions are also documented under +.Xr archive_write 3 . +.Sh RETURN VALUES +Most functions return +.Cm ARCHIVE_OK +(zero) on success, or one of several non-zero +error codes for errors. +Specific error codes include: +.Cm ARCHIVE_RETRY +for operations that might succeed if retried, +.Cm ARCHIVE_WARN +for unusual conditions that do not prevent further operations, and +.Cm ARCHIVE_FATAL +for serious errors that make remaining operations impossible. +The +.Fn archive_errno +and +.Fn archive_error_string +functions can be used to retrieve an appropriate error code and a +textual error message. +.Pp +.Fn archive_write_disk_new +returns a pointer to a newly-allocated +.Tn struct archive +object. +.Pp +.Fn archive_write_data +returns a count of the number of bytes actually written. +On error, -1 is returned and the +.Fn archive_errno +and +.Fn archive_error_string +functions will return appropriate values. +.Sh SEE ALSO +.Xr archive_read 3 , +.Xr archive_write 3 , +.Xr tar 1 , +.Xr libarchive 3 +.Sh HISTORY +The +.Nm libarchive +library first appeared in +.Fx 5.3 . +The +.Nm archive_write_disk +interface was added to +.Nm libarchive 2.0 +and first appeared in +.Fx 6.3 . +.Sh AUTHORS +.An -nosplit +The +.Nm libarchive +library was written by +.An Tim Kientzle Aq kientzle@acm.org . +.Sh BUGS +Directories are actually extracted in two distinct phases. +Directories are created during +.Fn archive_write_header , +but final permissions are not set until +.Fn archive_write_close . +This separation is necessary to correctly handle borderline +cases such as a non-writable directory containing +files, but can cause unexpected results. +In particular, directory permissions are not fully +restored until the archive is closed. +If you use +.Xr chdir 2 +to change the current directory between calls to +.Fn archive_read_extract +or before calling +.Fn archive_read_close , +you may confuse the permission-setting logic with +the result that directory permissions are restored +incorrectly. +.Pp +The library attempts to create objects with filenames longer than +.Cm PATH_MAX +by creating prefixes of the full path and changing the current directory. +Currently, this logic is limited in scope; the fixup pass does +not work correctly for such objects and the symlink security check +option disables the support for very long pathnames. +.Pp +Restoring the path +.Pa aa/../bb +does create each intermediate directory. +In particular, the directory +.Pa aa +is created as well as the final object +.Pa bb . +In theory, this can be exploited to create an entire directory heirarchy +with a single request. +Of course, this does not work if the +.Cm ARCHIVE_EXTRACT_NODOTDOT +option is specified. +.Pp +Implicit directories are always created obeying the current umask. +Explicit objects are created obeying the current umask unless +.Cm ARCHIVE_EXTRACT_PERM +is specified, in which case they current umask is ignored. +.Pp +SGID and SUID bits are restored only if the correct user and +group could be set. +If +.Cm ARCHIVE_EXTRACT_OWNER +is not specified, then no attempt is made to set the ownership. +In this case, SGID and SUID bits are restored only if the +user and group of the final object happen to match those specified +in the entry. +.Pp +The +.Dq standard +user-id and group-id lookup functions are not the defaults because +.Xr getgrnam 3 +and +.Xr getpwnam 3 +are sometimes too large for particular applications. +The current design allows the application author to use a more +compact implementation when appropriate. +.Pp +There should be a corresponding +.Nm archive_read_disk +interface that walks a directory heirarchy and returns archive +entry objects. \ No newline at end of file diff --git a/archivers/libarchive/files/libarchive/archive_write_disk.c b/archivers/libarchive/files/libarchive/archive_write_disk.c new file mode 100644

supported by the libarchive library +.Sh DESCRIPTION +The +.Xr libarchive 3 +library reads and writes a variety of streaming archive formats. +Generally speaking, all of these archive formats consist of a series of +.Dq entries . +Each entry stores a single file system object, such as a file, directory, +or symbolic link. +.Pp +The following provides a brief description of each format supported +by libarchive, with some information about recognized extensions or +limitations of the current library support. +Note that just because a format is supported by libarchive does not +imply that a program that uses libarchive will support that format. +Applications that use libarchive specify which formats they wish +to support, though many programs do use libarchive convenience +functions to enable all supported formats. +.Ss Tar Formats +The +.Xr libarchive 3 +library can read most tar archives. +However, it only writes POSIX-standard +.Dq ustar +and +.Dq pax interchange +formats. +.Pp +All tar formats store each entry in one or more 512-byte records. +The first record is used for file metadata, including filename, +timestamp, and mode information, and the file data is stored in +subsequent records. +Later variants have extended this by either appropriating undefined +areas of the header record, extending the header to multiple records, +or by storing special entries that modify the interpretation of +subsequent entries. +.Pp +.Bl -tag -width indent +.It Cm gnutar +The +.Xr libarchive 3 +library can read GNU-format tar archives. +It currently supports the most popular GNU extensions, including +modern long filename and linkname support, as well as atime and ctime data. +The libarchive library does not support multi-volume +archives, nor the old GNU long filename format. +It can read GNU sparse file entries, including the new POSIX-based +formats, but cannot write GNU sparse file entries. +.It Cm pax +The +.Xr libarchive 3 +library can read and write POSIX-compliant pax interchange format +archives. +Pax interchange format archives are an extension of the older ustar +format that adds a separate entry with additional attributes stored +as key/value pairs immediately before each regular entry. +The presence of these additional entries is the only difference between +pax interchange format and the older ustar format. +The extended attributes are of unlimited length and are stored +as UTF-8 Unicode strings. +Keywords defined in the standard are in all lowercase; vendors are allowed +to define custom keys by preceding them with the vendor name in all uppercase. +When writing pax archives, libarchive uses many of the SCHILY keys +defined by Joerg Schilling's +.Dq star +archiver and a few LIBARCHIVE keys. +The libarchive library can read most of the SCHILY keys +and most of the GNU keys introduced by GNU tar. +It silently ignores any keywords that it does not understand. +.It Cm restricted pax +The libarchive library can also write pax archives in which it +attempts to suppress the extended attributes entry whenever +possible. +The result will be identical to a ustar archive unless the +extended attributes entry is required to store a long file +name, long linkname, extended ACL, file flags, or if any of the standard +ustar data (user name, group name, UID, GID, etc) cannot be fully +represented in the ustar header. +In all cases, the result can be dearchived by any program that +can read POSIX-compliant pax interchange format archives. +Programs that correctly read ustar format (see below) will also be +able to read this format; any extended attributes will be extracted as +separate files stored in +.Pa PaxHeader +directories. +.It Cm ustar +The libarchive library can both read and write this format. +This format has the following limitations: +.Bl -bullet -compact +.It +Device major and minor numbers are limited to 21 bits. +Nodes with larger numbers will not be added to the archive. +.It +Path names in the archive are limited to 255 bytes. +(Shorter if there is no / character in exactly the right place.) +.It +Symbolic links and hard links are stored in the archive with +the name of the referenced file. +This name is limited to 100 bytes. +.It +Extended attributes, file flags, and other extended +security information cannot be stored. +.It +Archive entries are limited to 8 gigabytes in size. +.El +Note that the pax interchange format has none of these restrictions. +.El +.Pp +The libarchive library also reads a variety of commonly-used extensions to +the basic tar format. +These extensions are recognized automatically whenever they appear. +.Bl -tag -width indent +.It Numeric extensions. +The POSIX standards require fixed-length numeric fields to be written with +some character position reserved for terminators. +Libarchive allows these fields to be written without terminator characters. +This extends the allowable range; in particular, ustar archives with this +extension can support entries up to 64 gigabytes in size. +Libarchive also recognizes base-256 values in most numeric fields. +This essentially removes all limitations on file size, modification time, +and device numbers. +.It Solaris extensions +Libarchive recognizes ACL and extended attribute records written +by Solaris tar. +Currently, libarchive only has support for old-style ACLs; the +newer NFSv4 ACLs are recognized but discarded. +.El +.Pp +The first tar program appeared in Seventh Edition Unix in 1979. +The first official standard for the tar file format was the +.Dq ustar +(Unix Standard Tar) format defined by POSIX in 1988. +POSIX.1-2001 extended the ustar format to create the +.Dq pax interchange +format. +.Ss Cpio Formats +The libarchive library can read a number of common cpio variants and can write +.Dq odc +and +.Dq newc +format archives. +A cpio archive stores each entry as a fixed-size header followed +by a variable-length filename and variable-length data. +Unlike the tar format, the cpio format does only minimal padding +of the header or file data. +There are several cpio variants, which differ primarily in +how they store the initial header: some store the values as +octal or hexadecimal numbers in ASCII, others as binary values of +varying byte order and length. +.Bl -tag -width indent +.It Cm binary +The libarchive library transparently reads both big-endian and little-endian +variants of the original binary cpio format. +This format used 32-bit binary values for file size and mtime, +and 16-bit binary values for the other fields. +.It Cm odc +The libarchive library can both read and write this +POSIX-standard format, which is officially known as the +.Dq cpio interchange format +or the +.Dq octet-oriented cpio archive format +and sometimes unofficially referred to as the +.Dq old character format . +This format stores the header contents as octal values in ASCII. +It is standard, portable, and immune from byte-order confusion. +File sizes and mtime are limited to 33 bits (8GB file size), +other fields are limited to 18 bits. +.It Cm SVR4 +The libarchive library can read both CRC and non-CRC variants of +this format. +The SVR4 format uses eight-digit hexadecimal values for +all header fields. +This limits file size to 4GB, and also limits the mtime and +other fields to 32 bits. +The SVR4 format can optionally include a CRC of the file +contents, although libarchive does not currently verify this CRC. +.El +.Pp +Cpio first appeared in PWB/UNIX 1.0, which was released within +AT&T in 1977. +PWB/UNIX 1.0 formed the basis of System III Unix, released outside +of AT&T in 1981. +This makes cpio older than tar, although cpio was not included +in Version 7 AT&T Unix. +As a result, the tar command became much better known in universities +and research groups that used Version 7. +The combination of the +.Nm find +and +.Nm cpio +utilities provided very precise control over file selection. +Unfortunately, the format has many limitations that make it unsuitable +for widespread use. +Only the POSIX format permits files over 4GB, and its 18-bit +limit for most other fields makes it unsuitable for modern systems. +In addition, cpio formats only store numeric UID/GID values (not +usernames and group names), which can make it very difficult to correctly +transfer archives across systems with dissimilar user numbering. +.Ss Shar Formats +A +.Dq shell archive +is a shell script that, when executed on a POSIX-compliant +system, will recreate a collection of file system objects. +The libarchive library can write two different kinds of shar archives: +.Bl -tag -width indent +.It Cm shar +The traditional shar format uses a limited set of POSIX +commands, including +.Xr echo 1 , +.Xr mkdir 1 , +and +.Xr sed 1 . +It is suitable for portably archiving small collections of plain text files. +However, it is not generally well-suited for large archives +(many implementations of +.Xr sh 1 +have limits on the size of a script) nor should it be used with non-text files. +.It Cm shardump +This format is similar to shar but encodes files using +.Xr uuencode 1 +so that the result will be a plain text file regardless of the file contents. +It also includes additional shell commands that attempt to reproduce as +many file attributes as possible, including owner, mode, and flags. +The additional commands used to restore file attributes make +shardump archives less portable than plain shar archives. +.El +.Ss ISO9660 format +Libarchive can read and extract from files containing ISO9660-compliant +CDROM images. +In many cases, this can remove the need to burn a physical CDROM +just in order to read the files contained in an ISO9660 image. +It also avoids security and complexity issues that come with +virtual mounts and loopback devices. +Libarchive supports the most common Rockridge extensions and has partial +support for Joliet extensions. +If both extensions are present, the Joliet extensions will be +used and the Rockridge extensions will be ignored. +In particular, this can create problems with hardlinks and symlinks, +which are supported by Rockridge but not by Joliet. +.Ss Zip format +Libarchive can read and write zip format archives that have +uncompressed entries and entries compressed with the +.Dq deflate +algorithm. +Older zip compression algorithms are not supported. +It can extract jar archives, archives that use Zip64 extensions and many +self-extracting zip archives. +Libarchive reads Zip archives as they are being streamed, +which allows it to read archives of arbitrary size. +It currently does not use the central directory; this +limits libarchive's ability to support some self-extracting +archives and ones that have been modified in certain ways. +.Ss Archive (library) file format +The Unix archive format (commonly created by the +.Xr ar 1 +archiver) is a general-purpose format which is +used almost exclusively for object files to be +read by the link editor +.Xr ld 1 . +The ar format has never been standardised. +There are two common variants: +the GNU format derived from SVR4, +and the BSD format, which first appeared in 4.4BSD. +The two differ primarily in their handling of filenames +longer than 15 characters: +the GNU/SVR4 variant writes a filename table at the beginning of the archive; +the BSD format stores each long filename in an extension +area adjacent to the entry. +Libarchive can read both extensions, +including archives that may include both types of long filenames. +Programs using libarchive can write GNU/SVR4 format +if they provide a filename table to be written into +the archive before any of the entries. +Any entries whose names are not in the filename table +will be written using BSD-style long filenames. +This can cause problems for programs such as +GNU ld that do not support the BSD-style long filenames. +.Ss mtree +Libarchive can read and write files in +.Xr mtree 5 +format. +This format is not a true archive format, but rather a textual description +of a file hierarchy in which each line specifies the name of a file and +provides specific metadata about that file. +Libarchive can read all of the keywords supported by both +the NetBSD and FreeBSD versions of +.Xr mtree 1 , +although many of the keywords cannot currently be stored in an +.Tn archive_entry +object. +When writing, libarchive supports use of the +.Xr archive_write_set_options 3 +interface to specify which keywords should be included in the +output. +If libarchive was compiled with access to suitable +cryptographic libraries (such as the OpenSSL libraries), +it can compute hash entries such as +.Cm sha512 +or +.Cm md5 +from file data being written to the mtree writer. +.Pp +When reading an mtree file, libarchive will locate the corresponding +files on disk using the +.Cm contents +keyword if present or the regular filename. +If it can locate and open the file on disk, it will use that +to fill in any metadata that is missing from the mtree file +and will read the file contents and return those to the program +using libarchive. +If it cannot locate and open the file on disk, libarchive +will return an error for any attempt to read the entry +body. +.Sh SEE ALSO +.Xr ar 1 , +.Xr cpio 1 , +.Xr mkisofs 1 , +.Xr shar 1 , +.Xr tar 1 , +.Xr zip 1 , +.Xr

archives +.Sh LIBRARY +.Lb libarchive +.Sh OVERVIEW +The +.Nm +library provides a flexible interface for reading and writing +streaming archive files such as tar and cpio. +The library is inherently stream-oriented; readers serially iterate through +the archive, writers serially add things to the archive. +In particular, note that there is no built-in support for +random access nor for in-place modification. +.Pp +When reading an archive, the library automatically detects the +format and the compression. +The library currently has read support for: +.Bl -bullet -compact +.It +old-style tar archives, +.It +most variants of the POSIX +.Dq ustar +format, +.It +the POSIX +.Dq pax interchange +format, +.It +GNU-format tar archives, +.It +most common cpio archive formats, +.It +ISO9660 CD images (with or without RockRidge extensions), +.It +Zip archives. +.El +The library automatically detects archives compressed with +.Xr gzip 1 , +.Xr bzip2 1 , +or +.Xr compress 1 +and decompresses them transparently. +.Pp +When writing an archive, you can specify the compression +to be used and the format to use. +The library can write +.Bl -bullet -compact +.It +POSIX-standard +.Dq ustar +archives, +.It +POSIX +.Dq pax interchange format +archives, +.It +POSIX octet-oriented cpio archives, +.It +two different variants of shar archives. +.El +Pax interchange format is an extension of the tar archive format that +eliminates essentially all of the limitations of historic tar formats +in a standard fashion that is supported +by POSIX-compliant +.Xr pax 1 +implementations on many systems as well as several newer implementations of +.Xr tar 1 . +Note that the default write format will suppress the pax extended +attributes for most entries; explicitly requesting pax format will +enable those attributes for all entries. +.Pp +The read and write APIs are accessed through the +.Fn archive_read_XXX +functions and the +.Fn archive_write_XXX +functions, respectively, and either can be used independently +of the other. +.Pp +The rest of this manual page provides an overview of the library +operation. +More detailed information can be found in the individual manual +pages for each API or utility function. +.Sh READING AN ARCHIVE +To read an archive, you must first obtain an initialized +.Tn struct archive +object from +.Fn archive_read_new . +You can then modify this object for the desired operations with the +various +.Fn archive_read_set_XXX +and +.Fn archive_read_support_XXX +functions. +In particular, you will need to invoke appropriate +.Fn archive_read_support_XXX +functions to enable the corresponding compression and format +support. +Note that these latter functions perform two distinct operations: +they cause the corresponding support code to be linked into your +program, and they enable the corresponding auto-detect code. +Unless you have specific constraints, you will generally want +to invoke +.Fn archive_read_support_compression_all +and +.Fn archive_read_support_format_all +to enable auto-detect for all formats and compression types +currently supported by the library. +.Pp +Once you have prepared the +.Tn struct archive +object, you call +.Fn archive_read_open +to actually open the archive and prepare it for reading. +There are several variants of this function; +the most basic expects you to provide pointers to several +functions that can provide blocks of bytes from the archive. +There are convenience forms that allow you to +specify a filename, file descriptor, +.Ft "FILE *" +object, or a block of memory from which to read the archive data. +Note that the core library makes no assumptions about the +size of the blocks read; +callback functions are free to read whatever block size is +most appropriate for the medium. +.Pp +Each archive entry consists of a header followed by a certain +amount of data. +You can obtain the next header with +.Fn archive_read_next_header , +which returns a pointer to an +.Tn struct archive_entry +structure with information about the current archive element. +If the entry is a regular file, then the header will be followed +by the file data. +You can use +.Fn archive_read_data +(which works much like the +.Xr read 2 +system call) +to read this data from the archive. +You may prefer to use the higher-level +.Fn archive_read_data_skip , +which reads and discards the data for this entry, +.Fn archive_read_data_to_buffer , +which reads the data into an in-memory buffer, +.Fn archive_read_data_to_file , +which copies the data to the provided file descriptor, or +.Fn archive_read_extract , +which recreates the specified entry on disk and copies data +from the archive. +In particular, note that +.Fn archive_read_extract +uses the +.Tn struct archive_entry +structure that you provide it, which may differ from the +entry just read from the archive. +In particular, many applications will want to override the +pathname, file permissions, or ownership. +.Pp +Once you have finished reading data from the archive, you +should call +.Fn archive_read_close +to close the archive, then call +.Fn archive_read_finish +to release all resources, including all memory allocated by the library. +.Pp +The +.Xr archive_read 3 +manual page provides more detailed calling information for this API. +.Sh WRITING AN ARCHIVE +You use a similar process to write an archive. +The +.Fn archive_write_new +function creates an archive object useful for writing, +the various +.Fn archive_write_set_XXX +functions are used to set parameters for writing the archive, and +.Fn archive_write_open +completes the setup and opens the archive for writing. +.Pp +Individual archive entries are written in a three-step +process: +You first initialize a +.Tn struct archive_entry +structure with information about the new entry. +At a minimum, you should set the pathname of the +entry and provide a +.Va struct stat +with a valid +.Va st_mode +field, which specifies the type of object and +.Va st_size +field, which specifies the size of the data portion of the object. +The +.Fn archive_write_header +function actually writes the header data to the archive. +You can then use +.Fn archive_write_data +to write the actual data. +.Pp +After all entries have been written, use the +.Fn archive_write_finish +function to release all resources. +.Pp +The +.Xr archive_write 3 +manual page provides more detailed calling information for this API. +.Sh DESCRIPTION +Detailed descriptions of each function are provided by the +corresponding manual pages. +.Pp +All of the functions utilize an opaque +.Tn struct archive +datatype that provides access to the archive contents. +.Pp +The +.Tn struct archive_entry +structure contains a complete description of a single archive +entry. +It uses an opaque interface that is fully documented in +.Xr archive_entry 3 . +.Pp +Users familiar with historic formats should be aware that the newer +variants have eliminated most restrictions on the length of textual fields. +Clients should not assume that filenames, link names, user names, or +group names are limited in length.

+advanced clients may use +.Xr mmap 2 +to read the entire file into memory at once and return the +entire file to libarchive as a single block; +other clients may begin asynchronous I/O operations for the +next block on each request. +.Ss Decompresssion Layer +The decompression layer not only handles decompression, +it also buffers data so that the format handlers see a +much nicer I/O model. +The decompression API is a two stage peek/consume model. +A read_ahead request specifies a minimum read amount; +the decompression layer must provide a pointer to at least +that much data. +If more data is immediately available, it should return more: +the format layer handles bulk data reads by asking for a minimum +of one byte and then copying as much data as is available. +.Pp +A subsequent call to the +.Fn consume +function advances the read pointer. +Note that data returned from a +.Fn read_ahead +call is guaranteed to remain in place until +the next call to +.Fn read_ahead . +Intervening calls to +.Fn consume +should not cause the data to move. +.Pp +Skip requests must always be handled exactly. +Decompression handlers that cannot seek forward should +not register a skip handler; +the API layer fills in a generic skip handler that reads and discards data. +.Pp +A decompression handler has a specific lifecycle: +.Bl -tag -compact -width indent +.It Registration/Configuration +When the client invokes the public support function, +the decompression handler invokes the internal +.Fn __archive_read_register_compression +function to provide bid and initialization functions. +This function returns +.Cm NULL +on error or else a pointer to a +.Cm struct decompressor_t . +This structure contains a +.Va void * config +slot that can be used for storing any customization information. +.It Bid +The bid function is invoked with a pointer and size of a block of data. +The decompressor can access its config data +through the +.Va decompressor +element of the +.Cm archive_read +object. +The bid function is otherwise stateless. +In particular, it must not perform any I/O operations. +.Pp +The value returned by the bid function indicates its suitability +for handling this data stream. +A bid of zero will ensure that this decompressor is never invoked. +Return zero if magic number checks fail. +Otherwise, your initial implementation should return the number of bits +actually checked. +For example, if you verify two full bytes and three bits of another +byte, bid 19. +Note that the initial block may be very short; +be careful to only inspect the data you are given. +(The current decompressors require two bytes for correct bidding.) +.It Initialize +The winning bidder will have its init function called. +This function should initialize the remaining slots of the +.Va struct decompressor_t +object pointed to by the +.Va decompressor +element of the +.Va archive_read +object. +In particular, it should allocate any working data it needs +in the +.Va data +slot of that structure. +The init function is called with the block of data that +was used for tasting. +At this point, the decompressor is responsible for all I/O +requests to the client callbacks. +The decompressor is free to read more data as and when +necessary. +.It Satisfy I/O requests +The format handler will invoke the +.Va read_ahead , +.Va consume , +and +.Va skip +functions as needed. +.It Finish +The finish method is called only once when the archive is closed. +It should release anything stored in the +.Va data +and +.Va config +slots of the +.Va decompressor +object. +It should not invoke the client close callback. +.El +.Ss Format Layer +The read formats have a similar lifecycle to the decompression handlers: +.Bl -tag -compact -width indent +.It Registration +Allocate your private data and initialize your pointers. +.It Bid +Formats bid by invoking the +.Fn read_ahead +decompression method but not calling the +.Fn consume +method. +This allows each bidder to look ahead in the input stream. +Bidders should not look further ahead than necessary, as long +look aheads put pressure on the decompression layer to buffer +lots of data. +Most formats only require a few hundred bytes of look ahead; +look aheads of a few kilobytes are reasonable. +(The ISO9660 reader sometimes looks ahead by 48k, which +should be considered an upper limit.) +.It Read header +The header read is usually the most complex part of any format. +There are a few strategies worth mentioning: +For formats such as tar or cpio, reading and parsing the header is +straightforward since headers alternate with data. +For formats that store all header data at the beginning of the file, +the first header read request may have to read all headers into +memory and store that data, sorted by the location of the file +data. +Subsequent header read requests will skip forward to the +beginning of the file data and return the corresponding header. +.It Read Data +The read data interface supports sparse files; this requires that +each call return a block of data specifying the file offset and +size. +This may require you to carefully track the location so that you +can return accurate file offsets for each read. +Remember that the decompressor will return as much data as it has. +Generally, you will want to request one byte, +examine the return value to see how much data is available, and +possibly trim that to the amount you can use. +You should invoke consume for each block just before you return it. +.It Skip All Data +The skip data call should skip over all file data and trailing padding. +This is called automatically by the API layer just before each +header read. +It is also called in response to the client calling the public +.Fn data_skip +function. +.It Cleanup +On cleanup, the format should release all of its allocated memory. +.El +.Ss API Layer +XXX to do XXX +.Sh WRITE ARCHITECTURE +The write API has a similar set of four layers: +an API layer, a format layer, a compression layer, and an I/O layer. +The registration here is much simpler because only +one format and one compression can be registered at a time. +.Ss I/O Layer and Client Callbacks +XXX To be written XXX +.Ss Compression Layer +XXX To be written XXX +.Ss Format Layer +XXX To be written XXX +.Ss API Layer +XXX To be written XXX +.Sh WRITE_DISK ARCHITECTURE +The write_disk API is intended to look just like the write API +to clients. +Since it does not handle multiple formats or compression, it +is not layered internally. +.Sh GENERAL SERVICES +The +.Nm archive_read , +.Nm archive_write , +and +.Nm archive_write_disk +objects all contain an initial +.Nm archive +object which provides common support for a set of standard services. +(Recall that ANSI/ISO C90 guarantees that you can cast freely between +a pointer to a structure and a pointer to the first element of that +structure.) +The +.Nm archive +object has a magic value that indicates which API this object +is associated with, +slots for storing error information, +and function pointers for virtualized API functions. +.Sh MISCELLANEOUS NOTES +Connecting existing archiving libraries into libarchive is generally +quite difficult. +In particular, many existing libraries strongly assume that you +are reading from a file; they seek forwards and backwards as necessary +to locate various pieces of information. +In contrast, libarchive never seeks backwards in its input, which +sometimes requires very different approaches. +.Pp +For example, libarchive's ISO9660 support operates very differently +from most ISO9660 readers. +The libarchive support utilizes a work-queue design that +keeps a list of known entries sorted by their location in the input. +Whenever libarchive's ISO9660 implementation is asked for the next +header, checks this list to find the next item on the disk. +Directories are parsed when they are encountered and new +items are added to the list. +This design relies heavily on the ISO9660 image being optimized so that +directories always occur earlier on the disk than the files they +describe. +.Pp +Depending on the specific format, such approaches may not be possible. +The ZIP format specification, for example, allows archivers to store +key information only at the end of the file. +In theory, it is possible to create ZIP archives that cannot +be read without seeking. +Fortunately, such archives are very rare, and libarchive can read +most ZIP archives, though it cannot always extract as much information +as a dedicated ZIP program. +.Sh SEE ALSO +.Xr archive 3 , +.Xr archive_entry 3 , +.Xr archive_read 3 , +.Xr archive_write 3 , +.Xr archive_write_disk 3 +.Sh HISTORY +The +.Nm libarchive +library first appeared in +.Fx 5.3 . +.Sh AUTHORS +.An -nosplit +The +.Nm libarchive +library was written by +.An Tim Kientzle Aq kientzle@acm.org . +.Sh BUGS diff --git a/archivers/libarchive/files/libarchive/mtree.5 b/archivers/libarchive/files/libarchive/mtree.5 new file mode 100644 index 00000000000..b6637d6f55e --- /dev/null +++ b/archivers/libarchive/files/libarchive/mtree.5 @@ -0,0 +1,269 @@ +.\" Copyright (c) 1989, 1990, 1993 +.\" The Regents of the University of California.

collection of filesystem objects. +Such files are typically used to create or verify directory hierarchies. +.Ss General Format +An +.Nm +file consists of a series of lines, each providing information +about a single filesystem object. +Leading whitespace is always ignored. +.Pp +When encoding file or pathnames, any backslash character or +character outside of the 95 printable ASCII characters must be +encoded as a a backslash followed by three +octal digits. +When reading mtree files, any appearance of a backslash +followed by three octal digits should be converted into the +corresponding character. +.Pp +Each line is interpreted independently as one of the following types: +.Bl -tag -width Cm +.It Signature +The first line of any mtree file must begin with +.Dq #mtree . +If a file contains any full path entries, the first line should +begin with +.Dq #mtree v2.0 , +otherwise, the first line should begin with +.Dq #mtree v1.0 . +.It Blank +Blank lines are ignored. +.It Comment +Lines beginning with +.Cm # +are ignored. +.It Special +Lines beginning with +.Cm / +are special commands that influence +the interpretation of later lines. +.It Relative +If the first whitespace-delimited word has no +.Cm / +characters, +it is the name of a file in the current directory. +Any relative entry that describes a directory changes the +current directory. +.It dot-dot +As a special case, a relative entry with the filename +.Pa .. +changes the current directory to the parent directory. +Options on dot-dot entries are always ignored. +.It Full +If the first whitespace-delimited word has a +.Cm / +character after +the first character, it is the pathname of a file relative to the +starting directory. +There can be multiple full entries describing the same file. +.El +.Pp +Some tools that process +.Nm +files may require that multiple lines describing the same file +occur consecutively. +It is not permitted for the same file to be mentioned using +both a relative and a full file specification. +.Ss Special commands +Two special commands are currently defined: +.Bl -tag -width Cm +.It Cm /set +This command defines default values for one or more keywords. +It is followed on the same line by one or more whitespace-separated +keyword definitions. +These definitions apply to all following files that do not specify +a value for that keyword. +.It Cm /unset +This command removes any default value set by a previous +.Cm /set +command. +It is followed on the same line by one or more keywords +separated by whitespace. +.El +.Ss Keywords +After the filename, a full or relative entry consists of zero +or more whitespace-separated keyword definitions. +Each such definition consists of a key from the following +list immediately followed by an '=' sign +and a value. +Software programs reading mtree files should warn about +unrecognized keywords. +.Pp +Currently supported keywords are as follows: +.Bl -tag -width Cm +.It Cm cksum +The checksum of the file using the default algorithm specified by +the +.Xr cksum 1 +utility. +.It Cm contents +The full pathname of a file that holds the contents of this file. +.It Cm flags +The file flags as a

of files, directories, and other +file system objects (symbolic links, device nodes, etc.) into a single +stream of bytes. +The format was originally designed to be used with +tape drives that operate with fixed-size blocks, but is widely used as +a general packaging mechanism. +.Ss General Format +A +.Nm +archive consists of a series of 512-byte records. +Each file system object requires a header record which stores basic metadata +(pathname, owner, permissions, etc.) and zero or more records containing any +file data. +The end of the archive is indicated by two records consisting +entirely of zero bytes. +.Pp +For compatibility with tape drives that use fixed block sizes, +programs that read or write tar files always read or write a fixed +number of records with each I/O operation. +These +.Dq blocks +are always a multiple of the record size. +The maximum block size supported by early +implementations was 10240 bytes or 20 records. +This is still the default for most implementations +although block sizes of 1MiB (2048 records) or larger are +commonly used with modern high-speed tape drives. +(Note: the terms +.Dq block +and +.Dq record +here are not entirely standard; this document follows the +convention established by John Gilmore in documenting +.Nm pdtar . ) +.Ss Old-Style Archive Format +The original tar archive format has been extended many times to +include additional information that various implementors found +necessary. +This section describes the variant implemented by the tar command +included in +.At v7 , +which seems to be the earliest widely-used version of the tar program. +.Pp +The header record for an old-style +.Nm +archive consists of the following: +.Bd -literal -offset indent +struct header_old_tar { + char name[100]; + char mode[8]; + char uid[8]; + char gid[8]; + char size[12]; + char mtime[12]; + char checksum[8]; + char linkflag[1]; + char linkname[100]; + char pad[255]; +}; +.Ed +All unused bytes in the header record are filled with nulls. +.Bl -tag -width indent +.It Va name +Pathname, stored as a null-terminated string. +Early tar implementations only stored regular files (including +hardlinks to those files). +One common early convention used a trailing "/" character to indicate +a directory name, allowing directory permissions and owner information +to be archived and restored. +.It Va mode +File mode, stored as an octal number in ASCII. +.It Va uid , Va gid +User id and group id of owner, as octal numbers in ASCII. +.It Va size +Size of file, as octal number in ASCII. +For regular files only, this indicates the amount of data +that follows the header. +In particular, this field was ignored by early tar implementations +when extracting hardlinks. +Modern writers should always store a zero length for hardlink entries. +.It Va mtime +Modification time of file, as an octal number in ASCII. +This indicates the number of seconds since the start of the epoch, +00:00:00 UTC January 1, 1970. +Note that negative values should be avoided +here, as they are handled inconsistently. +.It Va checksum +Header checksum, stored as an octal number in ASCII. +To compute the checksum, set the checksum field to all spaces, +then sum all bytes in the header using unsigned arithmetic. +This field should be stored as six octal digits followed by a null and a space +character. +Note that many early implementations of tar used signed arithmetic +for the checksum field, which can cause interoperability problems +when transferring archives between systems. +Modern robust readers compute the checksum both ways and accept the +header if either computation matches. +.It Va linkflag , Va linkname +In order to preserve hardlinks and conserve tape, a file +with multiple links is only written to the archive the first +time it is encountered. +The next time it is encountered, the +.Va linkflag +is set to an ASCII +.Sq 1 +and the +.Va linkname +field holds the first name under which this file appears. +(Note that regular files have a null value in the +.Va linkflag +field.) +.El +.Pp +Early tar implementations varied in how they terminated these fields. +The tar command in +.At v7 +used the following conventions (this is also documented in early BSD manpages): +the pathname must be null-terminated; +the mode, uid, and gid fields must end in a space and a null byte; +the size and mtime fields must end in a space; +the checksum is terminated by a null and a space. +Early implementations filled the numeric fields with leading spaces. +This seems to have been common practice until the +.St -p1003.1-88 +standard was released. +For best portability, modern implementations should fill the numeric +fields with leading zeros. +.Ss Pre-POSIX Archives +An early draft of +.St -p1003.1-88 +served as the basis for John Gilmore's +.Nm pdtar +program and many system implementations from the late 1980s +and early 1990s. +These archives generally follow the POSIX ustar +format described below with the following variations: +.Bl -bullet -compact -width indent +.It +The magic value is +.Dq ustar\ \& +(note the following space). +The version field contains a space character followed by a null. +.It +The numeric fields are generally filled with leading spaces +(not leading zeros as recommended in the final standard). +.It +The prefix field is often not used, limiting pathnames to +the 100 characters of old-style archives. +.El +.Ss POSIX ustar Archives +.St -p1003.1-88 +defined a standard tar file format to be read and written +by compliant implementations of +.Xr tar 1 . +This format is often called the +.Dq ustar +format, after the magic value used +in the header. +(The name is an acronym for +.Dq Unix Standard TAR . ) +It extends the historic format with new fields: +.Bd -literal -offset indent +struct header_posix_ustar { + char name[100]; + char mode[8]; + char uid[8]; + char gid[8]; + char size[12]; + char mtime[12]; + char checksum[8]; + char typeflag[1]; +

7 +Reserved. +.It Other +A POSIX-compliant implementation must treat any unrecognized typeflag value +as a regular file. +In particular, writers should ensure that all entries +have a valid filename so that they can be restored by readers that do not +support the corresponding extension. +Uppercase letters "A" through "Z" are reserved for custom extensions. +Note that sockets and whiteout entries are not archivable. +.El +It is worth noting that the +.Va size +field, in particular, has different meanings depending on the type. +For regular files, of course, it indicates the amount of data +following the header. +For directories, it may be used to indicate the total size of all +files in the directory, for use by operating systems that pre-allocate +directory space. +For all other

+format, it can be split at any +.Pa / +character with the first portion going into the prefix field. +If the prefix field is not empty, the reader will prepend +the prefix value and a +.Pa / +character to the regular name field to obtain the full pathname. +The standard does not require a trailing +.Pa / +character on directory names, though most implementations still +include this for compatibility reasons. +.El +.Pp +Note that all unused bytes must be set to +.Dv NUL . +.Pp +Field termination is specified slightly differently by POSIX +than by previous implementations. +The +.Va magic , +.Va uname , +and +.Va gname +fields must have a trailing +.Dv NUL . +The +.Va pathname , +.Va linkname , +and +.Va prefix +fields must have a trailing +.Dv NUL +unless they fill the entire field. +(In particular, it is possible to store a 256-character pathname if it +happens to have a +.Pa / +as the 156th character.) +POSIX requires numeric fields to be zero-padded in the front, and requires +them to be terminated with either space or +.Dv NUL +characters. +.Pp +Currently, most tar implementations comply with the ustar +format, occasionally extending it by adding new fields to the +blank area at the end of the header record. +.Ss Pax Interchange Format +There are many attributes that cannot be portably stored in a +POSIX ustar archive. +.St -p1003.1-2001 +defined a +.Dq pax interchange format +that uses two new types of entries to hold text-formatted +metadata that applies to following entries. +Note that a pax interchange format archive is a ustar archive in every +respect. +The new data is stored in ustar-compatible archive entries that use the +.Dq x +or +.Dq g +typeflag. +In particular, older implementations that do not fully support these +extensions will extract the metadata into regular files, where the +metadata can be examined as necessary. +.Pp +An entry in a pax interchange format archive consists of one or +two standard ustar entries, each with its own header and data. +The first optional entry stores the extended attributes +for the following entry. +This optional first entry has an "x" typeflag and a size field that +indicates the total size of the extended attributes. +The extended attributes themselves are stored as a series of text-format +lines encoded in the portable UTF-8 encoding. +Each line consists of a decimal number, a space, a key string, an equals +sign, a value string, and a new line. +The decimal number indicates the length of the entire line, including the +initial length field and the trailing newline. +An example of such a field is: +.Dl 25 ctime=1084839148.1212\en +Keys in all lowercase are standard keys. +Vendors can add their own keys by prefixing them with an all uppercase +vendor name and a period. +Note that, unlike the historic header, numeric values are stored using +decimal, not octal. +A description of some common keys follows: +.Bl -tag -width indent +.It Cm atime , Cm ctime , Cm mtime +File access, inode change, and modification times. +These fields can be negative or include a decimal point and a fractional value. +.It Cm uname , Cm uid , Cm gname , Cm gid +User name, group name, and numeric UID and GID values. +The user name and group name stored here are encoded in UTF8 +and can thus include non-ASCII characters. +The UID and GID fields can be of arbitrary length. +.It Cm linkpath +The full path of the linked-to file. +Note that this is encoded in UTF8 and can thus include non-ASCII characters. +.It Cm path +The full pathname of the entry. +Note that this is encoded in UTF8 and can thus include non-ASCII characters. +.It Cm realtime.* , Cm security.* +These keys are reserved and may be used for future standardization. +.It Cm size +The size of the file. +Note that there is no length limit on this field, allowing conforming +archives to store files much larger than the historic 8GB limit. +.It Cm SCHILY.* +Vendor-specific attributes used by Joerg Schilling's +.Nm star +implementation. +.It Cm SCHILY.acl.access , Cm SCHILY.acl.default +Stores the access and default ACLs as textual strings in a format +that is an extension of the format specified by POSIX.1e draft 17. +In particular, each user or group access specification can include a fourth +colon-separated field with the numeric UID or GID. +This allows ACLs to be restored on systems that may not have complete +user or group information available (such as when NIS/YP or LDAP services +are temporarily unavailable). +.It Cm SCHILY.devminor , Cm SCHILY.devmajor +The full minor and major numbers for device nodes. +.It Cm SCHILY.fflags +The file flags. +.It Cm SCHILY.realsize +The full size of the file on disk. +XXX explain? XXX +.It Cm SCHILY.dev, Cm SCHILY.ino , Cm SCHILY.nlinks +The device number, inode number, and link count for the entry. +In particular, note that a pax interchange format archive using Joerg +Schilling's +.Cm SCHILY.* +extensions can store all of the data from +.Va struct stat . +.It Cm LIBARCHIVE.xattr. Ns Ar namespace Ns . Ns Ar key +Libarchive stores POSIX.1e-style extended attributes using +keys of this form. +The +.Ar key +value is URL-encoded: +All non-ASCII characters and the two special characters +.Dq = +and +.Dq % +are encoded as +.Dq % +followed by two uppercase hexadecimal digits. +The value of this key is the extended attribute value +encoded in base 64. +XXX Detail the base-64 format here XXX +.It Cm VENDOR.* +XXX document other vendor-specific extensions XXX +.El +.Pp +Any values stored in an extended attribute override the corresponding +values in the regular tar header. +Note that compliant readers should ignore the regular fields when they +are overridden. +This is important, as existing archivers are known to store non-compliant +values in the standard header fields in this situation. +There are no limits on length for any of these fields. +In particular, numeric fields can be arbitrarily large. +All text fields are encoded in UTF8. +Compliant writers should store only portable 7-bit ASCII characters in +the standard ustar header and use extended +attributes whenever a text value contains non-ASCII characters. +.Pp +In addition to the +.Cm x +entry described above, the pax interchange format +also supports a +.Cm g +entry. +The +.Cm g +entry is identical in format, but specifies attributes that serve as +defaults for all subsequent archive entries. +The +.Cm g +entry is not widely used. +.Pp +Besides the new +.Cm x +and +.Cm g +entries, the pax interchange format has a few other minor variations +from the earlier ustar format. +The most troubling one is that hardlinks are permitted to have +data following them. +This allows readers to restore any hardlink to a file without +having to rewind the archive to find an earlier entry. +However, it creates complications for robust readers, as it is no longer +clear whether or not they should ignore the size field for hardlink entries. +.Ss GNU Tar Archives +The GNU tar program started with a pre-POSIX format similar to that +described earlier and has extended it using several different mechanisms: +It added new fields to the empty space in the header (some of which was later +used by POSIX for conflicting purposes); +it allowed the header to be continued over multiple records; +and it defined new entries that modify following entries +(similar in principle to the +.Cm x +entry described above, but each GNU special entry is single-purpose, +unlike the general-purpose +.Cm x +entry). +As a result, GNU tar archives are not POSIX compatible, although +more lenient POSIX-compliant readers can successfully extract most +GNU tar archives. +.Bd -literal -offset indent +struct header_gnu_tar { + char name[100];

a program restoring from +such an archive may wish to delete files on disk that did not exist +in the directory when the archive was made. +.Pp +Note that the "D" typeflag specifically violates POSIX, which requires +that unrecognized typeflags be restored as normal files. +In this case, restoring the "D" entry as a file could interfere +with subsequent creation of the like-named directory. +.It "K" +The data for this entry is a long linkname for the following regular entry. +.It "L" +The data for this entry is a long pathname for the following regular entry. +.It "M" +This is a continuation of the last file on the previous volume. +GNU multi-volume archives guarantee that each volume begins with a valid +entry header. +To ensure this, a file may be split, with part stored at the end of one volume, +and part stored at the beginning of the next volume. +The "M" typeflag indicates that this entry continues an existing file. +Such entries can only occur as the first or second entry +in an archive (the latter only if the first entry is a volume label). +The +.Va size +field specifies the size of this entry. +The +.Va offset +field at bytes 369-380 specifies the offset where this file fragment +begins. +The +.Va realsize +field specifies the total size of the file (which must equal +.Va size +plus +.Va offset ) . +When extracting, GNU tar checks that the header file name is the one it is +expecting, that the header offset is in the correct sequence, and that +the sum of offset and size is equal to realsize. +.It "N" +Type "N" records are no longer generated by GNU tar. +They contained a +list of files to be renamed or symlinked after extraction; this was +originally used to support long names. +The contents of this record +are a text description of the operations to be done, in the form +.Dq Rename %s to %s\en +or +.Dq Symlink %s to %s\en ; +in either case, both +filenames are escaped using K&R C syntax. +Due to security concerns, "N" records are now generally ignored +when reading archives. +.It "S" +This is a +.Dq sparse +regular file. +Sparse files are stored as a series of fragments. +The header contains a list of fragment offset/length pairs. +If more than four such entries are required, the header is +extended as necessary with +.Dq extra +header extensions (an older format that is no longer used), or +.Dq sparse +extensions. +.It "V" +The +.Va name +field should be interpreted as a tape/volume header name. +This entry should generally be ignored on extraction. +.El +.It Va magic +The magic field holds the five characters +.Dq ustar +followed by a space. +Note that POSIX ustar archives have a trailing null. +.It Va version +The version field holds a space character followed by a null. +Note that POSIX ustar archives use two copies of the ASCII digit +.Dq 0 . +.It Va atime , Va ctime +The time the file was last accessed and the time of +last change of file information, stored in octal as with +.Va mtime . +.It Va longnames +This field is apparently no longer used. +.It Sparse Va offset / Va numbytes +Each such structure specifies a single fragment of a sparse +file. +The two fields store values as octal numbers. +The fragments are each padded to a multiple of 512 bytes +in the archive. +On extraction, the list of fragments is collected from the +header (including any extension headers), and the data +is then read and written to the file at appropriate offsets. +.It Va isextended +If this is set to non-zero, the header will be followed by additional +.Dq sparse header +records. +Each such record contains information about as many as 21 additional +sparse blocks as shown here: +.Bd -literal -offset indent +struct gnu_sparse_header { + struct { + char offset[12]; + char numbytes[12]; + } sparse[21]; + char isextended[1]; + char padding[7]; +}; +.Ed +.It Va realsize +A binary representation of the file's complete size, with a much larger range +than the POSIX file size. +In particular, with +.Cm M +type files, the current entry is only a portion of the file. +In that case, the POSIX size field will indicate the size of this +entry; the +.Va realsize +field will indicate the total size of the file. +.El +.Ss GNU tar pax archives +GNU tar 1.14 (XXX check this XXX) and later will write +pax interchange format archives when you specify the +.Fl -posix +flag. +This format uses custom keywords to store sparse file information. +There have been three iterations of this support, referred to +as +.Dq 0.0 , +.Dq 0.1 , +and +.Dq 1.0 . +.Bl -tag -width indent +.It Cm GNU.sparse.numblocks , Cm GNU.sparse.offset , Cm GNU.sparse.numbytes , Cm GNU.sparse.size +The +.Dq 0.0 +format used an initial +.Cm GNU.sparse.numblocks +attribute to indicate the number of blocks in the file, a pair of +.Cm GNU.sparse.offset +and +.Cm GNU.sparse.numbytes +to indicate the offset and size of each block, +and a single +.Cm GNU.sparse.size +to indicate the full size of the file. +This is not the same as the size in the tar header because the +latter value does not include the size of any holes. +This format required that the order of attributes be preserved and +relied on readers accepting multiple appearances of the same attribute +names, which is not officially permitted by the standards. +.It Cm GNU.sparse.map +The +.Dq 0.1 +format used a single attribute that stored a comma-separated +list of decimal numbers. +Each pair of numbers indicated the offset and size, respectively, +of a block of data. +This does not work well if the archive is extracted by an archiver +that does not recognize this extension, since many pax implementations +simply discard unrecognized attributes. +.It Cm GNU.sparse.major , Cm GNU.sparse.minor , Cm GNU.sparse.name , Cm GNU.sparse.realsize +The +.Dq 1.0 +format stores the sparse block map in one or more 512-byte blocks +prepended to the file data in the entry body. +The pax attributes indicate the existence of this map +(via the +.Cm GNU.sparse.major +and +.Cm GNU.sparse.minor +fields) +and the full size of the file. +The +.Cm GNU.sparse.name +holds the true name of the file. +To avoid confusion, the name stored in the regular tar header +is a modified name so that extraction errors will be apparent +to users. +.El +.Ss Solaris Tar +XXX More Details Needed XXX +.Pp +Solaris tar (beginning with SunOS XXX 5.7 ?? XXX) supports an +.Dq extended +format that is fundamentally similar to pax interchange format, +with the following differences: +.Bl -bullet -compact -width indent +.It +Extended attributes are stored in an entry whose type is +.Cm X , +not +.Cm x , +as used by pax interchange format. +The detailed format of this entry appears to be the same +as detailed above for the +.Cm x +entry. +.It +An additional +.Cm A +entry is used to store an ACL for the following regular entry. +The body of this entry contains a seven-digit octal number +followed by a zero byte, followed by the +textual ACL description. +The octal value is the number of ACL entries +plus a constant that indicates the ACL type: 01000000 +for POSIX.1e ACLs and 03000000 for NFSv4 ACLs. +.El +.Ss AIX Tar +XXX More details needed XXX +.Ss Mac OS X Tar +The tar distributed with Apple's Mac OS X stores most regular files +as two separate entries in the tar archive. +The two entries have the same name except that the first +one has +.Dq ._ +added to the beginning of the name. +This first entry stores the +.Dq resource fork +with additional attributes for the file. +The Mac OS X +.Fn CopyFile +API is used to separate a file on disk into separate +resource and data streams and to reassemble those separate +streams when the file is restored to disk. +.Ss Other Extensions +One obvious extension to increase the size of files is to +eliminate the terminating characters from the various +numeric fields. +For example, the standard only allows the size field to contain +11 octal digits, reserving the twelfth byte for a trailing +NUL character. +Allowing 12 octal digits allows file sizes up to 64 GB. +.Pp +Another extension, utilized by GNU tar, star, and other newer +.Nm +implementations, permits binary numbers in the standard numeric fields. +This is flagged by setting the high bit of the first byte. +This permits 95-bit values for the length and time fields +and 63-bit values for the uid, gid, and device numbers. +GNU tar supports this extension for the +length, mtime, ctime, and atime fields. +Joerg Schilling's star program supports this extension for +all numeric fields. +Note that this extension is largely obsoleted by the extended attribute +record provided by the pax interchange format. +.Pp +Another early GNU extension allowed base-64 values rather than octal. +This extension was short-lived and is no longer supported by any +implementation. +.Sh SEE ALSO +.Xr ar 1 , +.Xr pax 1 , +.Xr tar 1 +.Sh STANDARDS +The +.Nm tar +utility is no longer a part of POSIX or the Single Unix Standard. +It

+.Op Ar options +.Op Ar patterns +.Sh DESCRIPTION +.Nm +creates and manipulates streaming archive files. +This implementation can extract from tar, pax, cpio, zip, jar, ar, +and ISO 9660 cdrom images and can create tar, pax, cpio, ar, +and shar archives. +.Pp +The first synopsis form shows a +.Dq bundled +option word. +This usage is provided for compatibility with historical implementations. +See COMPATIBILITY below for details. +.Pp +The other synopsis forms show the preferred usage. +The first option to +.Nm +is a mode indicator from the following list: +.Bl -tag -compact -width indent +.It Fl c +Create a new archive containing the specified items. +.It Fl r +Like +.Fl c , +but new entries are appended to the archive. +Note that this only works on uncompressed archives stored in regular files. +The +.Fl f +option is required. +.It Fl t +List archive contents to stdout. +.It Fl u +Like +.Fl r , +but new entries are added only if they have a modification date +newer than the corresponding entry in the archive. +Note that this only works on uncompressed archives stored in regular files. +The +.Fl f +option is required. +.It Fl x +Extract to disk from the archive. +If a file with the same name appears more than once in the archive, +each copy will be extracted, with later copies overwriting (replacing) +earlier copies. +.El +.Pp +In +.Fl c , +.Fl r , +or +.Fl u +mode, each specified file or directory is added to the +archive in the order specified on the command line. +By default, the contents of each directory are also archived. +.Pp +In extract or list mode, the entire command line +is read and parsed before the archive is opened. +The pathnames or patterns on the command line indicate +which items in the archive should be processed. +Patterns are shell-style globbing patterns as +documented in +.Xr tcsh 1 . +.Sh OPTIONS +Unless specifically stated otherwise, options are applicable in +all operating modes. +.Bl -tag -width indent +.It Cm @ Ns Pa archive +(c and r mode only) +The specified archive is opened and the entries +in it will be appended to the current archive. +As a simple example, +.Dl Nm Fl c Fl f Pa - Pa newfile Cm @ Ns Pa original.tar +writes a new archive to standard output containing a file +.Pa newfile +and all of the entries from +.Pa original.tar . +In contrast, +.Dl Nm Fl c Fl f Pa - Pa newfile Pa original.tar +creates a new archive with only two entries. +Similarly, +.Dl Nm Fl czf Pa - Fl -format Cm pax Cm @ Ns Pa - +reads an archive from standard input (whose format will be determined +automatically) and converts it into a gzip-compressed +pax-format archive on stdout. +In this way, +.Nm +can be used to convert archives from one format to another. +.It Fl b Ar blocksize +Specify the block size, in 512-byte records, for tape drive I/O. +As a rule, this argument is only needed when reading from or writing +to tape drives, and usually not even then as the default block size of +20 records (10240 bytes) is very common. +.It Fl C Ar directory +In c and r mode, this changes the directory before adding +the following files. +In x mode, change directories after opening the archive +but before extracting entries from the archive. +.It Fl -check-links +(c and r modes only) +Issue a warning message unless all links to each file are archived. +.It Fl -chroot +(x mode only) +.Fn chroot +to the current directory after processing any +.Fl C +options and before extracting any files. +.It Fl -exclude Ar pattern +Do not process files or directories that match the +specified pattern. +Note that exclusions take precedence over patterns or filenames +specified on the command line. +.It Fl -format Ar format +(c, r, u mode only) +Use the specified format for the created archive. +Supported formats include +.Dq cpio , +.Dq pax , +.Dq shar , +and +.Dq ustar . +Other formats may also be supported; see +.Xr libarchive-formats 5 +for more information about currently-supported formats. +In r

-exclude +take precedence over inclusions. +If no inclusions are explicitly specified, all entries are processed by +default. +The +.Fl -include +option is especially useful when filtering archives. +For example, the command +.Dl Nm Fl c Fl f Pa new.tar Fl -include='*foo*' Cm @ Ns Pa old.tgz +creates a new archive +.Pa new.tar +containing only the entries from +.Pa old.tgz +containing the string +.Sq foo . +.It Fl j +(c mode only) +Compress the resulting archive with +.Xr bzip2 1 . +In extract or list modes, this option is ignored. +Note that, unlike other +.Nm tar +implementations, this

extracted. +.It Fl L +(c and r mode only) +All symbolic links will be followed. +Normally, symbolic links are archived as such. +With this option, the target of the link will be archived instead. +.It Fl l +This is a synonym for the +.Fl -check-links +option. +.It Fl m +(x mode only) +Do not extract modification time. +By default, the modification time is set to the time stored in the archive. +.It

Rock Ridge extensions. +This is enabled by default, use +.Cm !rockridge +or +.Cm iso9660:!rockridge +to disable. +.It Cm gzip:compression-level +A decimal integer from 0 to 9 specifying the gzip compression level. +.It Cm xz:compression-level +A decimal integer from 0 to 9 specifying the xz compression level. +.It Cm mtree: Ns Ar keyword +The mtree writer module allows you to specify which mtree keywords +will be included in the output. +Supported keywords include: +.Cm cksum , Cm device , Cm flags , Cm gid , Cm gname , Cm indent , +.Cm link , Cm md5 , Cm mode , Cm nlink , Cm rmd160 , Cm sha1 , Cm sha256 , +.Cm sha384 , Cm sha512 , Cm size , Cm time , Cm uid , Cm uname . +The default is equivalent to: +.Dq device, flags, gid, gname, link, mode, nlink, size, time, type, uid, uname . +.It Cm mtree:all +Enables all of the above keywords. +You can also use +.Cm mtree:!all +to disable all keywords. +.It Cm mtree:use-set +Enable generation of +.Cm /set +lines in the output. +.It Cm mtree:indent +Produce human-readable output by indenting options and splitting lines +to fit into 80 columns. +.It Cm zip:compression Ns = Ns Ar type +Use +.Ar type +as compression method. +Supported values are store (uncompressed) and deflate (gzip algorithm). +.El +If a provided option is not supported by any module, that +is a fatal error. +.It Fl P +Preserve pathnames. +By default, absolute pathnames (those that begin with a / +character) have the leading slash removed both when creating archives +and extracting from them. +Also, +.Nm +will refuse to extract archive entries whose pathnames contain +.Pa .. +or whose target directory would be altered by a symlink. +This option suppresses these behaviors. +.It Fl p +(x mode only) +Preserve file permissions. +Attempt to restore the full permissions, including owner, file modes, file +flags and ACLs, if available, for each item extracted from the archive. +By default, newly-created files are owned by the user running +.Nm , +the file mode is restored for newly-created regular files, and +all other types of entries receive default permissions. +If +.Nm +is being run by root, the default is to restore the owner unless the +.Fl o +option is also specified. +.It Fl q ( Fl -fast-read ) +(x and t mode only) +Extract or list only the first archive entry that matches each pattern +or filename operand. +Exit as soon as each specified pattern or filename has been matched. +By default, the archive is always read to the very end, since +there can be multiple entries with the same name and, by convention, +later entries overwrite earlier entries. +This option is provided as a performance optimization. +.It Fl S +(x mode only) +Extract files as sparse files. +For every block on disk, check first if it contains only NULL bytes and seek +over it otherwise. +This works similiar to the conv=sparse option of dd. +.It Fl -strip-components Ar count +(x mode only) +Remove the specified number of leading path elements. +Pathnames with fewer elements will be silently skipped. +Note that the pathname is edited after checking inclusion/exclusion patterns +but before security checks. +.It Fl s Ar pattern +Modify file or archive member names according to +.Pa pattern . +The pattern has the format +.Ar /old/new/ Ns Op gps +where +.Ar old +is a basic regular expression, +.Ar new +is the replacement string of the matched part, +and the optional trailing letters modify +how the replacement is handled. +If +.Ar old +is not matched, the pattern is skipped. +Within +.Ar new , +~ is substituted with the match, \1 to \9 with the content of +the corresponding captured group. +The optional trailing g specifies that matching should continue +after the matched part and stopped on the first unmatched pattern. +The optional trailing s specifies that the pattern applies to the value +of symbolic links. +The optional trailing p specifies that after a successful substitution +the original path name and the new path name should be printed to +standard error. +.It Fl T Ar filename +In x or t mode, +.Nm +will read the list of names to be extracted from +.Pa filename . +In c mode, +.Nm +will read names to be archived from +.Pa filename . +The special name +.Dq -C +on a line by itself will cause the current directory to be changed to +the directory specified on the following line. +Names are terminated by newlines unless +.Fl -null +is specified. +Note that +.Fl -null +also disables the special handling of lines containing +.Dq -C . +.It Fl U +(x mode only) +Unlink files before creating them. +Without this option, +.Nm +overwrites existing files, which preserves existing hardlinks. +With this option, existing hardlinks will be broken, as will any +symlink that would affect the location of an extracted file. +.It Fl -use-compress-program Ar program +Pipe the input (in x or t mode) or the output (in c mode) through +.Pa program +instead of using the builtin compression support. +.It Fl v +Produce verbose output. +In create and extract modes, +.Nm +will list each file name as it is read from or written to +the archive. +In list mode, +.Nm +will produce output similar to that of +.Xr ls 1 . +Additional +.Fl v +options will provide additional detail. +.It Fl -version +Print version of +.Nm +and +.Nm libarchive , +and exit. +.It Fl w +Ask for confirmation for every action. +.It Fl X Ar filename +Read a list of exclusion patterns from the specified file. +See +.Fl -exclude +for more information about the handling of exclusions. +.It Fl y +(c mode only) +Compress the resulting archive with +.Xr bzip2 1 . +In extract or list modes, this option is ignored. +Note that, unlike other +.Nm tar +implementations, this implementation recognizes bzip2 compression +automatically when reading

+.Ar file.tar.gz +that contains two files +.Ar source.c +and +.Ar source.h : +.Dl Nm Fl czf Pa file.tar.gz Pa source.c Pa source.h +.Pp +To view a detailed table of contents for this +archive: +.Dl Nm Fl tvf Pa file.tar.gz +.Pp +To extract all entries from the archive on +the default tape drive: +.Dl Nm Fl x +.Pp +To examine the contents of an ISO 9660 cdrom image: +.Dl Nm Fl tf Pa image.iso +.Pp +To move file hierarchies, invoke +.Nm +as +.Dl Nm Fl cf Pa - Fl C Pa srcdir\ . | Nm Fl xpf Pa - Fl C Pa destdir +or more traditionally +.Dl cd srcdir \&; Nm Fl cf Pa -\ . | ( cd destdir \&; Nm Fl xpf Pa - ) +.Pp +In create mode, the list of files and directories to be archived +can also include directory change instructions of the form +.Cm -C Ns Pa foo/baz +and archive inclusions of the form +.Cm @ Ns Pa archive-file . +For example, the command line +.Dl Nm Fl c Fl f Pa new.tar Pa foo1 Cm @ Ns Pa old.tgz Cm -C Ns Pa /tmp Pa foo2 +will create a new archive +.Pa new.tar . +.Nm +will read the file +.Pa foo1 +from the current directory and add it to the output archive. +It will then read each entry from +.Pa old.tgz +and add those entries to the output archive. +Finally, it will switch to the +.Pa /tmp +directory and add +.Pa foo2 +to the output archive. +.Pp +An input file in +.Xr mtree 5 +format can be used to create an output archive with arbitrary ownership, +permissions, or names that differ from existing data on disk: +.Pp +.Dl $ cat input.mtree +.Dl #mtree +.Dl usr/bin uid=0 gid=0 mode=0755 type=dir +.Dl usr/bin/ls uid=0 gid=0 mode=0755 type=file content=myls +.Dl $ tar -cvf output.tar @input.mtree +.Pp +The +.Fl -newer +and +.Fl -newer-mtime +switches accept a variety of common date and time specifications, including +.Dq 12 Mar 2005 7:14:29pm , +.Dq 2005-03-12 19:14 , +.Dq 5 minutes ago , +and +.Dq 19:14 PST May 1 . +.Pp +The +.Fl -options +argument can be used to control various details of archive generation +or reading. +For example, you can generate mtree output which only contains +.Cm type , Cm time , +and +.Cm uid +keywords: +.Dl Nm Fl cf Pa file.tar Fl -format=mtree Fl -options='!all,type,time,uid' Pa dir +or you can set the compression level used by gzip or xz compression: +.Dl Nm Fl czf Pa file.tar Fl -options='compression-level=9' . +For more details, see the explanation of the +.Fn archive_read_set_options +and +.Fn archive_write_set_options +API calls that are described in +.Xr archive_read 3 +and +.Xr archive_write 3 . +.Sh COMPATIBILITY +The bundled-arguments format is supported for compatibility +with historic implementations. +It consists of an initial word (with no leading - character) in which +each character indicates an option. +Arguments follow as separate words. +The order of the arguments must match the order +of the corresponding characters in the bundled command word. +For example, +.Dl Nm Cm tbf 32 Pa file.tar +specifies three flags +.Cm t , +.Cm b , +and +.Cm f . +The +.Cm b +and +.Cm f +flags both require arguments, +so there must be two additional items +on the command line. +The +.Ar 32 +is the argument to the +.Cm b +flag, and +.Ar file.tar +is the argument to the +.Cm f +flag. +.Pp +The mode options c, r, t, u, and x and the options +b, f, l, m, o, v, and w comply with SUSv2. +.Pp +For maximum portability, scripts that invoke +.Nm tar +should use the bundled-argument format above, should limit +themselves to the +.Cm c , +.Cm t , +and +.Cm x +modes, and the +.Cm b , +.Cm f , +.Cm m , +.Cm v , +and +.Cm w +options. +.Pp +Additional long options are provided to improve compatibility with other +tar implementations. +.Sh SECURITY +Certain security issues are common to many archiving programs, including +.Nm . +In particular, carefully-crafted archives can request that +.Nm +extract files to locations outside of the target directory. +This can potentially be used to cause unwitting users to overwrite +files they did not intend to overwrite. +If the archive is being extracted by the superuser, any file +on the system can potentially be overwritten. +There are three ways this can happen. +Although +.Nm +has mechanisms to protect against each one, +savvy users should be aware of the implications: +.Bl -bullet -width indent +.It +Archive entries can have absolute pathnames. +By default, +.Nm +removes the leading +.Pa / +character from filenames before restoring them to guard against this problem. +.It +Archive entries can have pathnames that include +.Pa .. +components. +By default, +.Nm +will not extract files containing +.Pa .. +components in their pathname. +.It +Archive entries can exploit symbolic links to restore +files to other directories. +An archive can restore a symbolic link to another directory, +then use that link to restore a file into that directory. +To guard against this, +.Nm +checks each extracted path for symlinks. +If the final path element is a symlink, it will be removed +and replaced with the archive entry. +If +.Fl U +is specified, any intermediate symlink will also be unconditionally removed. +If neither +.Fl U +nor +.Fl P +is specified, +.Nm +will refuse to extract the entry. +.El +To protect yourself, you should be wary of any archives that +come from untrusted sources. +You should examine the contents of an archive with +.Dl Nm Fl tf Pa filename +before extraction. +You should use the +.Fl k +option to ensure that +.Nm +will not overwrite any existing files or the +.Fl U +option to remove any pre-existing files. +You should generally not extract archives while running with super-user +privileges. +Note that the +.Fl P +option to +.Nm +disables the security checks above and allows you to extract +an archive while preserving any absolute pathnames, +.Pa .. +components, or symlinks to other directories. +.Sh SEE ALSO +.Xr bzip2 1 , +.Xr compress 1 , +.Xr cpio 1 , +.Xr gzip 1 , +.Xr mt 1 , +.Xr pax 1 , +.Xr shar 1 , +.Xr libarchive 3 , +.Xr libarchive-formats 5 , +.Xr tar 5 +.Sh STANDARDS +There is no current POSIX standard for the tar command; it appeared +in +.St -p1003.1-96 +but was dropped from +.St -p1003.1-2001 . +The options used by this implementation were developed by surveying a +number of existing tar implementations as well as the old POSIX specification +for tar and the current POSIX specification for pax. +.Pp +The ustar and pax interchange file formats are defined by +.St -p1003.1-2001 +for the pax command. +.Sh HISTORY +A +.Nm tar +command appeared in Seventh Edition Unix, which was released in January, 1979. +There have been numerous other implementations, +many of which extended the file format. +John Gilmore's +.Nm pdtar +public-domain implementation (circa November, 1987) +was quite influential, and formed the basis of GNU tar. +GNU tar was included as the standard system tar +in +.Fx +beginning with +.Fx 1.0 . +.Pp +This is a complete re-implementation based on the +.Xr libarchive 3 +library. +.Sh BUGS +This program follows +.St -p1003.1-96 +for the definition of the +.Fl l +option. +Note that GNU tar prior to version 1.15 treated +.Fl l +as a synonym for the +.Fl -one-file-system +option. +.Pp +The +.Fl C Pa dir +option may differ from historic implementations. +.Pp +All archive output is written in correctly-sized blocks, even +if the output is being compressed. +Whether or not the last output block is padded to a full +block size varies depending on the format and the +output device. +For tar and cpio formats, the last block of output is padded +to a full block size if the output is being +written to standard output or to a character or block device such as +a tape drive. +If the output is being written to a regular file, the last block +will not be padded. +Many compressors, including +.Xr gzip 1 +and +.Xr bzip2 1 , +complain about the null padding when decompressing an archive created by +.Nm , +although they still extract it correctly. +.Pp +The compression and decompression is implemented internally, so +there may be insignificant differences between the compressed output +generated by +.Dl Nm Fl czf Pa - file +and that generated by +.Dl Nm Fl cf Pa - file | Nm gzip +.Pp +The default should be to read and write archives to the standard I/O paths, +but tradition (and POSIX) dictates otherwise. +.Pp +The +.Cm r +and +.Cm u +modes require that the archive be uncompressed +and located in a regular file on disk. +Other archives can be modified using +.Cm c +mode with the +.Pa @archive-file +extension. +.Pp +To archive a file called +.Pa @foo +or +.Pa -foo +you must specify it as +.Pa ./@foo +or +.Pa ./-foo , +respectively. +.Pp +In create mode, a leading +.Pa ./ +is always removed. +A leading +.Pa / +is stripped unless the +.Fl P +option is specified. +.Pp +There needs to be better support for file selection on both create +and extract. +.Pp +There is not yet any support for multi-volume archives or for archiving +sparse files. +.Pp +Converting between dissimilar archive formats (such as tar and cpio) using the +.Cm @ Ns Pa - +convention can cause hard link information to be lost. +(This is a consequence of the incompatible ways that different archive +formats store hardlink information.) +.Pp +There are alternative long options for many of the short options that +are deliberately not documented. diff --git a/archivers/libarchive/files/tar/bsdtar.c
