2006-05-17Update to 1.2.10:wiz2-14/+17
Package change: install old compat library as libpngcompat (pkgsrc specific, will probably be changed in the future). Makes package handling quite a bit easier. version 1.2.10beta1 [April 15, 2006] Renamed "config.h" to "png_conf.h" and revised Makefile.am to add -DPNG_BUILDING_LIBPNG to compile directive, and modified pngconf.h to include png_conf.h only when PNG_BUILDING_LIBPNG is defined. version 1.2.10beta2 [April 15, 2006] Manually updated Makefile.in and configure. Changed png_conf.h.in back to config.h. version 1.2.10beta3 [April 15, 2006] Change png_conf.h back to config.h in pngconf.h. version 1.2.10beta4 [April 16, 2006] Change PNG_BUILDING_LIBPNG to PNG_CONFIGURE_LIBPNG in config/Makefile*. version 1.2.10beta5 [April 16, 2006] Added a configure check for compiling assembler code in pnggccrd.c version 1.2.10beta6 [April 17, 2006] Revised the configure check for pnggccrd.c Moved -DPNG_CONFIGURE_LIBPNG into @LIBPNG_DEFINES@ Added @LIBPNG_DEFINES@ to arguments when building libpng.sym version 1.2.10beta7 [April 18, 2006] Change "exec_prefix=$prefix" to "exec_prefix=$(prefix)" in makefiles. version 1.2.10rc1 [April 19, 2006] Ensure pngconf.h doesn't define both PNG_USE_PNGGCCRD and PNG_USE_PNGVCRD Fixed "LN_FS" typo in makefile.sco and makefile.solaris. version 1.2.10rc2 [April 20, 2006] Added a backslash between -DPNG_CONFIGURE_LIBPNG and -DPNG_NO_ASSEMBLER_CODE in configure.ac and configure Made the configure warning about versioned symbols less arrogant. version 1.2.10rc3 [April 21, 2006] Added a note in libpng.txt that png_set_sig_bytes(8) can be used when writing an embedded PNG without the 8-byte signature. Revised makefiles and configure to avoid making links to libpng.so.* version 1.2.10 [April 23, 2006] Reverted configure to "rc2" state.
2006-04-17Update to 1.2.9nb2 (hopefully final update for this weekend):wiz1-11/+0
. add rpath to libpng-config output . link against libpng12 (instead of libpng) in all cases. The latter causes shlib dependency changes, so update BUILDLINK_ABI_DEPENDS.png.
2006-04-16Update to 1.2.9nb1:wiz3-81/+15
. pngconf.h included "config.h" if HAVE_CONFIG_H is defined -- really not a good idea, patch it out. broke at least libwmf, reported by veego@ . install some libpng12 files -- IIUC, libpng12* is the future and libpng* is becoming obsolete -- at least according to the wishes of the authors. Don't follow this completely yet, but still patch the pkg-config file to link against -lpng instead of -lpng12, which would require a recursive PKGREVISION bump. We should probably do this at some future time. . switch pkgconfig file to look for headers in include/libpng12 -- the headers still exist in include/ for backwards compatibility. . switch to using GNU_CONFIGURE and the included libtool handling instead of patching in our own into a Makefile. Gets rid of patches and pkgsrc Makefile code.

Added references to PNG Spec (second edition) and the PNG ISO/IEC Standard. * Added "test-dd" target in 15 makefiles, to run pngtest in DESTDIR. * Fixed bug with "optimized window size" in the IDAT datastream, that causes libpng to write PNG files with incorrect zlib header bytes. * Fixed bug with sCAL chunk and big-endian machines (David Munro). * Undid new code added in 1.2.6rc2 to update the color_type in png_set_filler(). * Added png_set_add_alpha() that updates color type. * Revised png_set_strip_filler() to not remove alpha if color_type has alpha. * Added makefile.hp64 * Changed projects/msvc/png32ms.def to scripts/png32ms.def in makefile.cygwin
2004-08-17update to 1.2.6 (first official release after the recentdrochner2-24/+13
security fixes) changes: version 1.2.6rc3 [August 9, 2004] Eliminated use of "abs()" in testing cHRM and gAMA values, to avoid trouble with some 64-bit compilers. Created PNG_OUT_OF_RANGE() macro. Revised documentation of png_set_keep_unknown_chunks(). Check handle_as_unknown status in pngpread.c, as in pngread.c previously. Moved "PNG_HANDLE_CHUNK_*" macros out of PNG_INTERNAL section of png.h Added "rim" definitions for CONST4 and CONST6 in pnggccrd.c version 1.2.6rc4 [August 10, 2004] Fixed mistake in pngtest.c introduced in 1.2.6rc2 (declaration of "pinfo" was out of place). version 1.2.6rc5 [August 10, 2004] Moved "PNG_HANDLE_CHUNK_*" macros out of PNG_ASSEMBLER_CODE_SUPPORTED section of png.h where they were inadvertently placed in version rc3. version 1.2.6rc6 [August 15, 2004] Revised pngtest so memory allocation testing is only done when PNG_DEBUG==1.

Adding an alpha channel to 16-bit *grayscale* images with png_do_read_filler() exhibits the same bug, and pngcrush crashes if I try to do it. To fix, at lines 1892, 1893, 1910, and 1911 of pngrtran.c change "row_width" to "row_width * 2" Note that applications that do not add an alpha channel via png_set_filler(), and any applications that do, but reduce 16-bit samples to 8 bit via png_set_strip_16() are invulnerable to the bug. Pngcrush is the only application that I know of that uses png_set_filler() without also using png_set_strip_16(). Glenn -- Send the message body "help" to png-implement-request@ccrc.wustl.edu

2002-07-19Update to version 1.2.4. Two new functions since 1.2.1, png_malloc_warn()fredb1-20/+24
and png_set_text_2(), call for a minor version bump in the shared library. Update "BUILDLINK_DEPENDS" to current level. Also make the shared library versions visible in the top-level "Makefile", and add a top-level "test" target to invoke "pngtest" in ${WRKSRC}. The following is culled from the extensive "CHANGES" file, ommitting all make system and doc changes, and some bug fixes for bugs that weren't present in 1.2.1. See "CHANGES" for complete details: Added setjmp() at the end of png_create_*_struct_2() in case user forgets to put one in their application. Exported png_zalloc(), png_zfree(), png_default_read(), png_default_write(), png_default_flush(), and png_push_fill_buffer() and included them in module definition files. Revised prototype for png_default_flush() Typos in *.def files (png_default_read|write -> png_default_read|write_data) Once more restored png_zalloc and png_zfree to regular nonexported form. Restored png_default_read|write_data, png_default_flush, png_read_fill_buffer to nonexported form, but with PNGAPI, and removed them from module def files. Removed "PNGAPI" from png_zalloc() and png_zfree() in png.c Plugged various memory leaks; added png_malloc_warn() and png_set_text_2() functions. Plugged memory leak of png_ptr->current_text (Matt Holgate). Check for buffer overflow before reading CRC in pngpread.c (Warwick Allison) Plugged memory leak of row_buf in pngtest.c when there is a png_error(). Detect buffer overflow in pngpread.c when IDAT is corrupted with extra data. Changed png_warning() to png_error() when width is too large to process.

2002-03-13Update png to 1.2.1. Includes an ABI change and a concommittent bump in thefredb1-2/+2
shared library version, and in the dependendency information for hundreds of other packages. [Update to png itself was supplied by Thomas Wizner.] Relevant changes since 1.0.12, extracted from the "CHANGES" file: Re-enabled PNG_MNG_FEATURES_SUPPORTED and enabled PNG_ASSEMBLER_CODE_SUPPORTED by default. Added runtime selection of MMX features. Added png_set_strip_error_numbers function and related macros. Added a check for attempts to read or write PLTE in grayscale PNG datastreams. Enabled user memory function by default. Modified png_create_struct so it passes user mem_ptr to user memory allocator. Increased png_mng_features flag from png_byte to png_uint_32. Check for missing profile length field in iCCP chunk and free chunk_data in case of truncated iCCP chunk. Revised contrib/gregbook/rpng*-x.c to avoid a memory leak and to exit cleanly if user attempts to run it on an 8-bit display. Updated contrib/gregbook Use png_malloc instead of png_zalloc to allocate palette in pngset.c Added some typecasts to eliminate gcc 3.0 warnings. Changed prototypes of png_write_oFFS width and height from png_uint_32 to png_int_32. Updated example.c Revised prototypes for png_debug_malloc and png_debug_free in pngtest.c Revised contrib/gregbook Revised pnggccrd.c to conditionally compile some thread-unsafe code only when PNG_THREAD_UNSAFE_OK is defined. Added tests to prevent pngwutil.c from writing a bKGD or tRNS chunk with value exceeding 2^bit_depth-1 Replaced calls to fprintf(stderr,...) with png_warning() in pnggccrd.c Removed restriction that do_invert_mono only operate on 1-bit opaque files Changed a png_warning() to png_debug() in pnggccrd.c Fixed contrib/gregbook/rpng-x.c, rpng2-x.c to avoid crash with XFreeGC(). Include background_1 in png_struct regardless of gamma support. Revised example.c to provide more details about using row_callback(). Added type cast to each NULL appearing in a function call, except for WINCE functions. Removed type casts from all NULLs. Simplified png_create_struct_2(). Revised png_create_info_struct() and png_creat_struct_2(). Added error message if png_write_info() was omitted. Type cast NULLs appearing in function calls when _NO_PROTO or PNG_TYPECAST_NULL is defined. Type cast NULLs appearing in function calls except when PNG_NO_TYPECAST_NULL is defined. Changed typecast of "size" argument to png_size_t in pngmem.c calls to the user malloc_fn, to agree with the prototype in png.h Added a pop/push operation to pnggccrd.c, to preserve Eflag (Maxim Sobolev) Added a pop/push operation to pngvcrd.c, to preserve Eflag. Always allocate 256-entry internal palette, hist, and trans arrays, to avoid out-of-bounds memory reference caused by invalid PNG datastreams. Added a check for prefix_length > data_length in iCCP chunk handler.
2001-08-03Update to 1.0.12. Extract of changes since 1.0.11:wiz1-2/+2
. Added some never-to-be-executed code in pnggccrd.c to quiet compiler warnings. . Added a check for attempts to read or write PLTE in grayscale PNG datastreams. . Eliminated the png_error about apps using png_read|write_init(). Instead, libpng will reallocate the png_struct and info_struct if they are too small. This achieves future binary compatibility for old applications written for libpng-0.88 and earlier. Expanded the warnings about incompatible library and application. . Modified png_create_struct so it passes user mem_ptr to user memory allocator. . Check for missing profile length field in iCCP chunk and free the chunk_data in case of truncated iCCP chunk.

pkgsrc change: bump shared library major like it happened in libpng some time ago -- our libtool'ified build didn't reflect this. Fixes pkg/12856 by Thor Simon. Note necessity of manual major/minor handling in Makefile, to decrease chance that this will repeat in the future. Changes since 1.0.10: Added type casts on several png_malloc() calls (Dimitri Papadapoulos). Removed a no-longer needed AIX work-around from pngconf.h Changed several "//" single-line comments to C-style in pnggccrd.c Removed PNGAPI from several functions whose prototypes did not have PNGAPI. Updated scripts/pngos2.def Added a check for NULL return from user's malloc_fn(). Removed some useless type casts of the NULL pointer.

Changes are: Changed sprintf() to strcpy() in png_write_sCAL_s() to work without STDIO Added data_length parameter to png_decompress_chunk() function Revised documentation to remove reference to abandoned png_free_chnk functions Fixed an error in png_rgb_to_gray_fixed() Revised example.c, usage of png_destroy_write_struct(). Renamed makefile.ibmvac3 to makefile.ibmc, added libpng.icc IBM project file Added a check for info_ptr->free_me&PNG_FREE_TEXT when free'ing text in png.c Simplify png_sig_bytes() function to remove use of non-ISO-C strdup(). Added png_data_freer() function. In the code that checks for over-length tRNS chunks, added check of info_ptr->num_trans as well as png_ptr->num_trans (Matthias Benckmann) Check for existing data and free it if the free_me flag is set, in png_set_*() and png_handle_*(). Only define PNG_WEIGHTED_FILTERS_SUPPORTED when PNG_FLOATING_POINT_SUPPORTED is defined. Changed several instances of PNG_NO_CONSOLE_ID to PNG_NO_STDIO in pngrutil.c and mentioned the purposes of the two macros in libpng.txt/libpng.3. Revised png_set_iCCP() and png_set_rows() to avoid prematurely freeing data. Add checks in png_set_text() for NULL members of the input text structure. Removed superfluous prototype for png_set_itxt from png.h Removed "else" from pngread.c, after png_error(), and changed "0" to "length". Changed several png_errors about malformed ancillary chunks to png_warnings. Added png_pass-* arrays to pnggccrd.c when PNG_USE_LOCAL_ARRAYS is defined. Relocated paragraph about png_set_background() in libpng.3/libpng.txt and other revisions (Matthias Benckmann) Relocated info_ptr->free_me to restore binary compatibility with libpng-1.0.5 (breaks compatibility with libpng-1.0.6). Relocated info_ptr->free_me, png_ptr->free_me, and other info_ptr and png_ptr members to restore binary compatibility with libpng-1.0.5 (breaks compatibility with libpng-1.0.6). Rearranged some members at the end of png_info and png_struct, to put unknown_chunks_num and free_me within the original size of the png_structs and free_me, png_read_user_fn, and png_free_fn within the original png_info, because some old applications allocate the structs directly instead of using png_create_*(). Added documentation of user memory functions in libpng.txt/libpng.3 Modified png_read_png so that it will use user_allocated row_pointers if present, unless free_me directs that it be freed, and added description of the use of png_set_rows() and png_get_rows() in libpng.txt/libpng.3. Added PNG_LEGACY_SUPPORTED macro, and #ifdef out all new (since version 1.00) members of png_struct and png_info, to regain binary compatibility when you define this macro. Capabilities lost in this event are user transforms (new in version 1.0.0),the user transform pointer (new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT, the high-level interface, and unknown chunks support (all new in 1.0.6). This was necessary because of old applications that allocate the structs directly as authors were instructed to do in libpng-0.88 and earlier, instead of using png_create_*(). Added makefile.intel and updated makefile.watcom (Pawel Mrochen) Overloaded png_read_init() and png_write_init() with macros that convert calls to png_read_init_2() or png_write_init_2() that check the version and structure sizes. Made PNG_NO_ITXT_SUPPORTED the default setting, to avoid memory overrun when old applications fill the info_ptr->text structure directly. Added PNGAPI macro, and added it to the definitions of all exported functions. Relocated version macro definitions ahead of the includes of zlib.h and pngconf.h in png.h. Made PNG_NO_CONSOLE_IO the default condition when PNG_BUILD_DLL is defined. Use MSC _RPTn debugging instead of fprintf if _MSC_VER is defined. Added png_access_version_number() function. Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data(). Expanded libpng.3/libpng.txt information about png_data_freer(). Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as warnings instead of errors, as pngrutil.c does. Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png() will actually write IDATs. Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32. Make png_free_data() ignore its final parameter when freeing data that can have multiple instances (text, sPLT, unknowns). Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5. Added png_set_invalid() function. Fixed incorrect illustrations of png_destroy_write_struct() in example.c. Revised the deliberately erroneous Linux setjmp code in pngconf.h to produce fewer error messages. Set each pointer to NULL after freeing it in png_free_data(). Worked around a problem in pngconf.h; AIX's strings.h defines an "index" macro that conflicts with libpng's png_color_16.index. (Dimitri Papadapoulos) Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler. Added a check for overlength PLTE chunk in pngrutil.c. Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler. Added a warning in png_decompress_chunk() when it runs out of data. Revised the copyright/disclaimer/license notice. Corrected the definition of PNG_TRANSFORM_INVERT_ALPHA (0x0400 not 0x0200) Added PNG_USE_DLL macro. Added "msvc" and contrib/msvctest directories with MSVC++ project files (Simon-Pierre Cadieux) and contrib/visupng directory (Willem van Schaik). Removed leading underscores from "_PNG_H" and "_PNG_SAVE_BSD_SOURCE" macros. Fixed bugs in pngwrite.c and pngwutil.c that prevented writing iCCP chunks. Revised the definition of "trans_values" in libpng.3/libpng.txt
