2011-02-04Fix building with Clangadam2-1/+24
2011-02-03Update to 1.5.1:wiz2-6/+6
Version 1.5.1beta10 [January 27, 2010] Fixed incorrect examples of callback prototypes in the manual, that were introduced in libpng-1.0.0. In addition the order of the png_get_uint macros with respect to the relevant function definitions has been reversed. This helps the preprocessing of the symbol files be more robust. Furthermore, the symbol file preprocessing now uses -DPNG_NO_USE_READ_MACROS even when the library may actually be built with PNG_USE_READ_MACROS; this stops the read macros interfering with the symbol file format. Made the manual, synopses, and function prototypes use the function argument names file_gamma, int_file_gamma, and srgb_intent consistently. Version 1.5.1beta11 [January 28, 2011] Changed PNG_UNUSED from "param=param;" to "{if(param){}}". Corrected local variable type in new API png_process_data_skip() The type was self-evidently incorrect but only causes problems on 64 bit architectures. Added transform tests to pngvalid and simplified the arguments. Version 1.5.1rc01 [January 29, 2011] No changes. Version 1.5.1rc02 [January 31, 2011] Added a request in the manual that applications do not use "png_" or "PNG_" to begin any of their own symbols. Changed PNG_UNUSED to "(void)param;" and updated the commentary in pngpriv.h Version 1.5.1 [February 3, 2011] No changes.
2011-01-24Changes 1.5.1beta09:adam3-9/+9
Enhanced pngvalid, corrected an error in gray_to_rgb, corrected doc error. pngvalid contains tests of transforms, which tests are currently disabled because they are incompletely tested. gray_to_rgb was failing to expand the bit depth for smaller bit depth images; this seems to be a long standing error and resulted, apparently, in invalid output. The documentation did not accurately describe what libpng really does when converting RGB to gray.
2011-01-23Update to 1.5.1beta08. Integrates a better version of patch-ac and trieswiz3-20/+6
to fix the Solaris build problem reported in PR 44428. Version 1.5.1beta07 [January 22, 2011] In the manual, describe the png_get_IHDR() arguments in the correct order. Added const_png_structp and const_png_infop types, and used them in prototypes for most png_get_*() functions. Version 1.5.1beta08 [January 23, 2011] Added png_get_io_chunk_type() and deprecated png_get_io_chunk_name() Added synopses for the IO_STATE functions and other missing synopses to the manual. Removed the synopses from libpngpf.3 because they were out of date and no longer useful. Better information can be obtained by reading the prototypes and comments in pngpriv.h Attempted to fix cpp on Solaris with S. Studio 12 cc, fix build Added a make macro DFNCPP that is a CPP that will accept the tokens in a .dfn file and adds configure stuff to test for such a CPP. ./configure should fail if one is not available. Corrected const_png_ in png.h to png_const_ to avoid polluting the namespace. Added png_get_current_row_number and png_get_current_pass_number for the benefit of the user transform callback. Added png_process_data_pause and png_process_data_skip for the benefit of progressive readers that need to stop data processing or want to optimize skipping of unread data (e.g., if the reader marks a chunk to be skipped.)
2011-01-21Update to 1.5.1beta06:wiz2-6/+6
Version 1.5.1beta02 [January 14, 2011] Fixed a bug in handling of interlaced images (bero at arklinux.org). Updated CMakeLists.txt (Clifford Yapp) Version 1.5.1beta03 [January 14, 2011] Fixed typecasting of some png_debug() statements (Cosmin) Version 1.5.1beta04 [January 16, 2011] Updated documentation of png_set|get_tRNS() (Thomas Klausner). Mentioned in the documentation that applications must #include "zlib.h" if they need access to anything in zlib.h, and that a number of macros such as png_memset() are no longer accessible by applications. Corrected pngvalid gamma test "sample" function to access all of the color samples of each pixel, instead of sampling the red channel three times. Prefixed variable names index, div, exp, gamma with "png_" to avoid "shadow" warnings, and (mistakenly) changed png_exp() to exp(). Version 1.5.1beta05 [January 16, 2011] Changed variable names png_index, png_div, png_exp, and png_gamma to char_index, divisor, exp_b10, and gamma_val, respectively, and changed exp() back to png_exp(). Version 1.5.1beta06 [January 20, 2011] Prevent png_push_crc_skip() from hanging while reading an unknown chunk or an over-large compressed zTXt chunk with the progressive reader. Eliminated more GCC "shadow" warnings. Revised png_fixed() in png.c to avoid compiler warning about reaching the end without returning anything.
2011-01-13Update to 1.5.1beta01:wiz6-39/+23
1.5.1beta01 contains a security fix for 1.5.0. The current public release, libpng 1.5.0, continues the evolution of the libpng API, finally hiding the contents of the venerable and hoary png_struct and png_info data structures inside private (i.e., non-installed) header files. (Apps that compiled with libpng 1.4 without warnings about deprecated features should happily compile with 1.5, too.) It also includes a new, more thorough test program (pngvalid.c), a new pnglibconf.h header file that tracks what features were enabled or disabled when libpng was built, and huge thanks to John Bowler, who did most of the work. Complete differences relative to libpng 1.4.x are detailed at http://www.libpng.org/pub/png/src/libpng-1.4.x-to-1.5.x-summary.txt . Since the shlib name changed, next up: PKGREVISION++ all across pkgsrc.
2010-12-10Update to 1.4.5:wiz2-6/+6
version 1.4.5beta01 [September 25, 2010] Fixed possible configure.ac bug introduced in version 1.4.4rc05. Rebuilt configure scripts with autoconf-2.68 instead of autoconf-2.65 version 1.4.5beta02 [October 5, 2010] Reverted configure scripts to autoconf-2.65 Fixed problem with symbols creation in Makefile.am which was assuming that all versions of cpp write to standard output by default (Martin Banky). The bug was introduced in libpng-1.2.9beta5. version 1.4.5beta03 [October 8, 2010] Wrapped long lines in CMakeLists.txt and introduced ${libpng_public_hdrs} Undid Makefile.am revision of 1.4.5beta02. version 1.4.5beta04 [November 8, 2010] Check for out-of-range text compression mode in png_set_text(). version 1.4.5rc01 [November 19, 2010] No changes. version 1.4.5beta05 [November 20, 2010] Revised png_get_uint_32, png_get_int_32, png_get_uint_16 (Cosmin) Moved reading of file signature into png_read_sig (Cosmin) Fixed atomicity of chunk header serialization (Cosmin) Added test for io_state in pngtest.c (Cosmin) Added "#!/bin/sh" at the top of contrib/pngminim/*/gather.sh scripts. version 1.4.5beta06 [November 21, 2010] Restored the parentheses in pngrutil.c; they are needed when the png_get_*int_*() functions are compiled (i.e., when PNG_USE_READ_MACROS is not defined). Make the "png_get_uint_16" macro return a png_uint_32 in libpng-1.4 for API compatibility. Changes to remove gcc warnings (John Bowler) Certain optional gcc warning flags resulted in warnings in libpng code. With these changes only -Wconversion and -Wcast-qual cannot be turned on. Changes are trivial rearrangements of code. -Wconversion is not possible for pngrutil.c (because of the widespread use of += et al on variables smaller than (int) or (unsigned int)) and -Wcast-qual is not possible with pngwio.c and pngwutil.c because the 'write' callback and zlib compression both fail to declare their input buffers with 'const'. version 1.4.5beta07 [November 25, 2010] Reverted png_get_uint_16 macro to beta05 and added comment about the potential API incompatibility. version 1.4.5rc02 [December 2, 2010] No changes. version 1.4.5rc03 [December 3, 2010] Added missing vstudio/*/*.vcxproj files to the zip and 7z distributions. version 1.4.5 [December 9, 2010] Removed PNG_NO_WRITE_GAMMA from pngminim/encoder/pngusr.h
2010-09-24Update to 1.4.4:wiz5-19/+26
version 1.4.4beta01 [July 12, 2010] Removed extraneous new_push_process_row.c file. Revised the "SEE ALSO" style of libpng.3, libpngpf.3, and png.5 Removed some newly-added TAB characters from pngpread.c. Fixed some indentation in pngpread.c and pngrutil.c Changed "extern PNG_EXPORT" to "PNG_EXPORT" in png.h (Jan Nijtmans) Changed "extern" to "PNG_EXTERN" in pngpriv.h (except for the 'extern "C" {') Put "#ifndef PNG_EXTERN, #endif" around "#define PNG_EXTERN" in pngpriv.h version 1.4.4beta02 [July 24, 2010] Added -DNO_PNG_SNPRINTF to CFLAGS in scripts/makefile.dj2 Moved the definition of png_snprintf() outside of the enclosing #ifdef blocks in pngconf.h Added a special case typedef of png_longjmp_ptr for WATCOM. version 1.4.4beta03 [July 24, 2010] Removed reference to cbuilder5/* from Makefile.in and Makefile.am Eliminated the new special case typedef of png_longjmp_ptr for WATCOM and made a special case "#define PNGAPI" in pngconf.h instead. version 1.4.4beta04 [July 31, 2010] Updated the read macros and functions from 1.5.0beta38. version 1.4.4beta05 [August 6, 2010] Updated projects/visualc71 so it can find scripts/pnglibconf.h Removed unused png_mem_* defines from pngconf.h. Correct use of _WINDOWS_ in pngconf.h version 1.4.4beta06 [August 11, 2010] Don't try to use version-script with cygwin/mingw. Revised contrib/gregbook to work under cygwin/mingw. version 1.4.4beta07 [August 26, 2010] Updated prebuilt aclocal.m4 and ltmain.sh Add .dll.a to the list of extensions to be symlinked by Makefile.am (Yaakov) Updated CMakeLists.txt to use CMAKE_INSTALL_LIBDIR variable; useful for installing libpng in /usr/lib64 (Funda Wang). Revised CMakeLists.txt to put the man pages in share/man/man* not man/man* Revised CMakeLists.txt to make symlinks instead of copies when installing. Changed PNG_LIB_NAME from pngNN to libpngNN in CMakeLists.txt (Philip Lowman) Moved "#include pngusr.h" ahead of PNG_USER_PRIVATEBUILD test in pngconf.h Eliminated a deprecated reference to png_ptr->io_ptr in pngtest.c Eliminated new unnecessary #if tests regarding the sCAL chunk from pngrutil.c version 1.4.4beta08 [September 2, 2010] Updated the xcode project to work with libpng-1.4.x and added iOS targets for simulator and device (Philippe Hausler). version 1.4.4rc01 [September 10, 2010] No changes. version 1.4.4rc02 [September 13, 2010] Revised CMakeLists.txt (Philip Lowman). version 1.4.4rc03 [September 14, 2010] Removed an extraneous close-double-quote from CMakeLists.txt Eliminated another deprecated reference to png_ptr->io_ptr in pngtest.c version 1.4.4rc04 [September 16, 2010] Fixed indentation and removed debugging message from CMakeLists.txt Revised autogen.sh to recognize and use $AUTOCONF, $AUTOMAKE, $AUTOHEADER, $AUTOPOINT, $ACLOCAL and $LIBTOOLIZE version 1.4.4rc05 [September 20, 2010] Rebuilt configure scripts with automake-1.11.1 instead of automake-1.11. Removed unused mkinstalldirs file. version 1.4.4 [September 23, 2010] No changes.
2010-06-26Security update to 1.4.3:wiz2-6/+6
Several versions of libpng through 1.4.2 (and through 1.2.43 in the older series) contain a bug whereby progressive applications such as web browsers (or the rpng2 demo app included in libpng) could receive an extra row of image data beyond the height reported in the header, potentially leading to an out-of-bounds write to memory (depending on how the application is written) and the possibility of execution of an attacker's code with the privileges of the libpng user (including remote compromise in the case of a libpng-based browser visiting a hostile web site). This vulnerability has been assigned ID CVE-2010-1205 (via Mozilla). An additional memory-leak bug, involving images with malformed sCAL chunks, is also present; it could lead to an application crash (denial of service) when viewing such images. Both bugs are fixed in versions 1.4.3 and 1.2.44. version 1.4.3beta01 [June 18, 2010] Added missing quotation marks in the aix block of configure.ac The new "vstudio" project was missing from the zip and 7z distributions. In pngpread.c: png_push_have_row() add check for new_row > height version 1.4.3beta02 [June 18, 2010] Removed the now-redundant check for out-of-bounds new_row from example.c version 1.4.3beta03 [June 18, 2010] In pngpread.c: png_push_finish_row() add check for too many rows. version 1.4.3beta04 [June 19, 2010] In pngpread.c: png_push_process_row() add check for too many rows. Removed the checks added in beta01 and beta03, as they are now redundant. version 1.4.3beta05 [June 20, 2010] Rewrote png_process_IDAT_data to consistently treat extra data as warnings and handle end conditions more cleanly. Removed the new (beta04) check in png_push_process_row(). version 1.4.3rc01 [June 21, 2010] Revised some comments in png_process_IDAT_data(). version 1.4.3rc02 [June 22, 2010] Changed char *msg to PNG_CONST char *msg in pngrutil.c Stop memory leak when reading a malformed sCAL chunk. Removed some trailing blanks. version 1.4.3rc03 [June 23, 2010] Revised pngpread.c patch of beta05 to avoid an endless loop. version 1.4.3 [June 26, 2010] Updated some of the "last changed" dates.
2010-06-13Update to 1.4.2. Shared library name changes from libpn12.* to libpng14.*,wiz7-67/+40
so bump ABI depends. Remove libpng.* from package, instead use buildlink to help some packages that are looking for the library themselves instead of using pkg-config or libpng-config. Changes: version 1.4.2: Restored the macro definition of png_check_sig(). Conditionally compile an "else" statement in png_decompress_chunk(). Documented the fact that png_set_dither() was disabled since libpng-1.4.0. Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect more accurately what it actually does. At the same time, renamed the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS. Added some "(long)" typecasts to printf calls in png_handle_cHRM(). Relaxed the overly-restrictive permissions of some files. Added the "vstudio" project to replace "visualc6" and "visualc71" which will be removed from libpng-1.5.0. Demonstrate in example.c that lang_key should be initialized. Set PNG_NO_READ_BGR, PNG_NO_IO_STATE, and PNG_NO_TIME_RFC1123 in contrib/pngminim/decoder/pngusr.h to make a smaller decoder application. Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined. Removed dummy_inflate.c and uncompr.c from contrib/pngminim/encoder Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED in gregbook/readpng2.c Corrected protection of png_get_user_transform_ptr. The API declaration in png.h is removed if both READ and WRITE USER_TRANSFORM are turned off but was left defined in pngtrans.c Moved declarations of umsg[] inside the proper #ifdef blocks in pngrutil.c version 1.4.1 [February 25, 2010] Updated CMakeLists.txt for consistent indentation and to avoid an unclosed if-statement warning (Philip Lowman). Revised Makefile.am and Makefile.in to remove references to Y2KINFO, KNOWNBUG, and libpng.la (Robert Schwebel). Revised the makefiles to install the same files and symbolic except for libpng.la and libpng14.la. Make png_set|get_compression_buffer_size() available even when PNG_WRITE_SUPPORTED is not enabled. Revised Makefile.am and Makefile.in to simplify their maintenance. Revised the makefiles to install a link to libpng14.so.14.1 Removed png_set_premultiply_alpha() from scripts/*.def Revised png_decompress_chunk() to improve speed and memory usage when decoding large chunks, using a two-pass method suggested by John Bowler. Added png_set|get_chunk_malloc_max() functions. Relocated "int k" declaration in pngtest.c to minimize its scope. Folded some long lines in the source files. Added defineable PNG_USER_CHUNK_CACHE_MAX and PNG_USER_CHUNK_MALLOC_MAX Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as png_ptr->png_user_chunk_malloc_max. Return allocated "old_buffer" in png_push_save_buffer() before calling png_error(), to avoid a potential memory leak. Removed the cbuilder5 project, which has not been updated to 1.4.0. Complete rewrite of two-pass png_decompress_chunk() by John Bowler. Removed obsolete unused MMX-querying support from contrib/gregbook Removed the AIX redefinition of jmpbuf in png.h Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt when using AIX compiler. Removed unused gzio.c from contrib/pngminim gather and makefile scripts Changes to Libpng from version 1.2.42 to 1.4.0 (January 4, 2010) Libpng-1.4.0 was released by the PNG Development Group on January 3, 2010. Important new features include support for the iTXt chunk and a function for limiting the amount of memory that a possibly malicious compressed chunk can consume. Some long-deprecated functions and features have been removed. A new private header file that is not visible to applications has been created, to improve our ability to maintain binary compatibility among future libpng versions. Specifically, 1. Private libpng prototypes and macro definitions were moved from png.h and pngconf.h into a new pngpriv.h header file that is not visible to applications. 2. Some obsolete/deprecated macros and functions have been removed. a. We eliminated the obsolete, unused pnggccrd.c and pngvcrd.c files and related makefiles. b. We removed the typecasted NULL definitions such as #define png_voidp_NULL (png_voidp)NULL If you used these in your application, just use NULL instead. c. We eliminated the PNG_1_0_X and PNG_1_2_X macros. d. We eliminated the PNG_LEGACY_SUPPORTED macro. e. We removed many WIN32_WCE #ifdefs. f. We removed the functions png_read_init(info_ptr), png_write_init(info_ptr), png_info_init(info_ptr), png_read_destroy(), and png_write_destroy(). They have been deprecated since libpng-0.95. g. We removed the png_permit_empty_plte() function. It has been deprecated since libpng-1.0.9. Use png_permit_mng_features() instead. h. We removed the obsolete stub functions png_get_mmx_flagmask(), png_set_mmx_thresholds(), png_get_asm_flags(), png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(), png_set_asm_flags(), and png_mmx_supported() i. We removed the obsolete png_check_sig(), png_memcpy_check(), and png_memset_check() functions. Instead use !png_sig_cmp(), png_memcpy(), and png_memset(), respectively, i.e., replace png_check_sig(buf, 8) with png_sig_cmp(buf, 0, 8) == 0 replace png_memcpy_check(png_ptr, dest, src, length) with png_memcpy(dest, src, length) and replace png_memset_check(png_ptr, dest, value, length) with png_memset(dest, value, length) j. We removed support for global arrays to improve thread safety. k. We removed support for numbered error messages by default, since we never got around to actually numbering the error messages. The function png_set_strip_error_numbers() was removed from the library by default. l. The png_zalloc() and png_zfree() functions are no longer exported. The png_zalloc() function no longer zeroes out the memory that it allocates. m. The function png_set_gray_1_2_4_to_8() was removed. It has been deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with png_set_expand_gray_1_2_4_to_8() because the former function also expanded palette images. 3. Several function prototypes were changed. a. We changed the prototype for png_malloc() from png_malloc(png_structp png_ptr, png_uint_32 size) to png_malloc(png_structp png_ptr, png_alloc_size_t size) b. We changed the prototypes of png_get_compression_buffer_size() and png_set_compression_buffer_size() to work with png_size_t instead of png_uint_32. 4. We added some new features: a. We enabled iTXt chunk support by default. This changes the png_text structure by adding the itxt_length, lang, and lang_key members. b. We added the functions png_set_benign_errors(), png_benign_error(), and png_chunk_benign_error(). With these, you can choose to treat certain normally fatal errors as nonfatal. c. Support for setting the maximum amount of memory that the application will allocate for reading chunks was added, as a security measure. The functions png_set_chunk_cache_max() and png_get_chunk_cache_max() were added to the library. d. We added the png_calloc() function and used it in place of of "png_malloc(); png_memset();" except in the case in png_read_png() where the array consists of pointers; in this case a "for" loop is used after the png_malloc() to set the pointers to NULL, to give robust. behavior in case the application runs out of memory part-way through the process. e. We implemented support for I/O states by adding png_ptr member io_state and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c f. We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level input transforms. 5. Other changes a. We changed the names of the png_struct and info_struct members "trans" and "trans_values" to "trans_alpha" and "trans_color", respectively. b. Checking for and reporting of errors in the IHDR chunk is more thorough. c. We removed the trailing '.' from the warning and error messages. d. Direct access to png_ptr->jmpbuf has been deprecated since libpng version 1.0.6, and libpng now generates a warning about it. To avoid such warnings, change setjmp(png_ptr->jmpbuf) to setjmp(png_jmpbuf(png_ptr))
2010-03-09Update to 1.2.43:wiz2-7/+6
version 1.2.42beta01 [December 4, 2009] Removed "#define PNG_NO_ERROR_NUMBERS" that was inadvertently added to pngconf.h in version 1.2.41. Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco to put png.h and pngconf.h in $prefix/include, like the other scripts, instead of in $prefix/include/libpng. Also revised makefile.sco to put them in $prefix/include/libpng12 instead of in $prefix/include/libpng/libpng12. Removed leftover "-DPNG_CONFIGURE_LIBPNG" from scripts/makefile.darwin version 1.2.42beta02 [December 11, 2009] Removed leftover "-DPNG_CONFIGURE_LIBPNG" from contrib/pngminim/*/makefile Relocated png_do_chop() to its original position in pngrtran.c. The change in version 1.2.41beta08 caused transparency to be handled wrong in some 16-bit datastreams (Yusaku Sugai). version 1.2.42rc01 [December 17, 2009] No changes. version 1.2.42rc02 [December 22, 2009] Renamed libpng-pc.in back to libpng.pc.in and revised CMakeLists.txt (revising changes made in 1.2.41beta17 and 1.2.41rc01) version 1.2.42rc03 [December 25, 2009] Swapped PNG_UNKNOWN_CHUNKS_SUPPORTED and PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngset.c to be consistent with other changes in version 1.2.38. version 1.2.42rc04 [January 1, 2010] Marked png_memcpy_check() and png_memset_check() PNG_DEPRECATED. Updated copyright year. version 1.2.42rc05 [January 2, 2010] Avoid deprecated references to png_ptr-io_ptr and png_ptr->error_ptr in pngtest.c version 1.2.42 and 1.0.52 [January 3, 2010] No changes. version 1.2.43beta01 [January 27, 2010] Updated CMakeLists.txt for consistent indentation and to avoid an unclosed if-statement warning (Philip Lowman). Removed "#ifdef PNG_1_0_X / #endif" surrounding PNG_READ_16_TO_8_SUPPORTED and PNG_READ_GRAY_TO_RGB_SUPPORTED in pngconf.h. These were added in libpng-1.2.41beta08 and libpng-1.0.51, which introduced a binary incompatibility with libpng-1.0.50. Backported new png_decompress_chunk() algorithm from libpng-1.4.1. version 1.2.43beta02 [February 1, 2010] Backported two-pass png_decompress_chunk() algorithm from libpng-1.4.1. version 1.2.43beta03 [February 6, 2010] Backported fast png_push_save_buffer() algorithm from libpng-1.4.1. Backported some cosmetic changes from libpng-1.4.1. version 1.2.43beta04 [February 8, 2010] Reverted recent changes to png_push_save-buffer(). Removed PNGAPI declaration of png_calloc() and png_write_sig() in 1ibpng-1.2.X, introduced by mistake in libpng-1.2.41. Return allocated "old_buffer" in png_push_save_buffer() before png_error() to avoid a potential memory leak. version 1.2.43beta05 [February 8, 2010] Ported rewritten png_decompress_chunk() by John Bowler from libpng-1.4.1. version 1.0.53rc01 and 1.2.43rc01 [February 18, 2010] No changes. version 1.0.53rc02 and 1.2.43rc02 [February 19, 2010] Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt when using AIX compiler. version 1.0.53 and 1.2.43 [February 25, 2010] Removed unused gzio.c from contrib/pngminim gather and makefile scripts

2009-12-04Update to 1.2.41:wiz2-6/+6
version 1.2.41beta01 [September 25, 2009] Moved redundant IHDR checking into new png_check_IHDR() in png.c and report all errors found in the IHDR data. Eliminated useless call to png_check_cHRM() from pngset.c Expanded TAB characters in pngrtran.c version 1.2.41beta02 [September 30, 2009] Revised png_check_IHDR(). version 1.2.41beta03 [October 1, 2009] Revised png_check_IHDR() again, to check info_ptr members instead of the contents of the returned parameters. version 1.2.41beta04 [October 7, 2009] Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias). Ported some cosmetic changes from libpng-1.4.0beta86. Eliminated a shadowed declaration of "pp" in png_handle_sPLT(). version 1.2.41beta05 [October 17, 2009] Revised pngconf.h to make it easier to enable iTXt support. From libpng version 1.2.9 through 1.2.40, defining PNG_iTXt_SUPPORTED did not work as expected. Ported some cosmetic changes from libpng-1.4.0beta87, changing many "#if defined(x)" to "#ifdef x". version 1.2.41beta06 [October 18, 2009] Restored PNG_USE_LOCAL_ARRAYS code in pngread.c that was inadvertently deleted in libpng-1.2.41beta05. Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h as in libpng-1.4.0beta78 and later. version 1.2.41beta07 [October 21, 2009] Ported some cosmetic changes from libpng-1.4.0rc01, changing many "#if defined(x)" to "#ifdef x" in png.h and pngconf.h. version 1.2.41beta08 [October 30, 2009] Ported from libpng-1.4.0rc01: png_calloc(), png_get_io_chunk_name(), png_get_io_state(), png_set_user_cache_max(), png_get_user_cache_max(), png_set_premultiply_alpha, and png_do_read_premultiply_alpha(). Relocated png_do_chop() ahead of building gamma tables in pngrtran.c This avoids building 16-bit gamma tables unnecessarily. version 1.2.41beta09 [November 1, 2009] Removed a harmless extra png_set_invert_alpha() from pngwrite.c More bugfixes and improvements to CMakeLists.txt (Philip Lowman) Moved CMakeLists.txt from scripts into the main libpng directory. Apply png_user_chunk_cache_max within png_decompress_chunk(). Merged libpng-1.2.41.txt with libpng-1.4.0.txt where appropriate. version 1.2.41beta10 [November 1, 2009] Enabled iTXt support by default. To ensure binary compatibility with previous versions, the "lang" and "lang_key" members will be assumed to be omitted from previous versions unless the current libpng version was built with PNG_iTXt_SUPPORTED (which is otherwise no longer necessary to gain iTXt support), as a signal that the user has been building previous versions with PNG_iTXt_SUPPORTED as well. version 1.2.41beta11 [November 2, 2009] Store user's user_png_ver in new png_ptr->user_png_ver element. Revised iTXt support. To ensure binary compatibility with previous versions, the "lang" and "lang_key" members will be assumed to be omitted from versions prior to 1.2.41beta11 whenever there is a library mismatch. version 1.2.41beta12 [November 2, 2009] Free png_ptr->user_png_ver when destroying png_ptr. version 1.2.41beta13 [November 3, 2009] Updated scripts/pngw32.def and projects/wince/png32ce.def Copied projects/wince/png32ce.def to the scripts directory. Added scripts/makefile.wce Patched ltmain.sh for wince support. Added PNG_CONVERT_tIME_SUPPORTED macro. version 1.2.41beta14 [November 8, 2009] versions 1.2.41beta05 through 1.2.41beta13 were abandoned. The 1.0.x/1.2.x series will only receive security updates from now on. Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED Make #define PNG_CONVERT_tIME_SUPPORTED depend on PNG_WRITE_tIME_SUPPORTED Reverted iTXt compatibility stuff from 1.2.41beta05, 1.2.41beta11, and 1.2.41beta12. Reverted IOSTATE feature, user_cache_max, and premultiply_alpha features from 1.2.41beta08. Retained png_calloc() from 1.2.41beta08 but as a non-exported function, and removed reference to png_calloc from scripts/*.def version 1.2.41beta15 [November 8, 2009] Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and PNG_ALLOCATED macros to detect deprecated direct access to the png_struct or info_struct members and other deprecated usage in applications (John Bowler). Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS, to prevent warnings about direct access to png structs by libpng functions while building libpng. They need to be tested, especially those using compilers other than gcc. Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG". version 1.2.41beta16 [November 9, 2009] Removed three direct references to read_info_ptr members in pngtest.c that were detected by the new PNG_DEPSTRUCT macro. Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined. version 1.2.41beta17 [November 10, 2009] Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions. Marked deprecated function prototypes with PNG_DEPRECATED. Marked memory allocation function prototypes with PNG_ALLOCATED. Changed png_check_sig() to !png_sig_cmp() in contrib programs. Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c Added "-DPNG_CONFIGURE_LIBPNG" to the contrib/pngminum makefiles. version 1.2.41beta18 [November 11, 2009] Renamed scripts/makefile.wce to scripts/makefile.cegcc Marked nonexported functions with PNG_PRIVATE macro. version 1.2.41rc01 and 1.0.51rc01 [November 18, 2009] Revised scripts/*.def to reflect functions actually exported by libpng. Updated the copyright year in scripts/pngw32.rc from 2004 to 2009. Moved descriptions of makefiles and other scripts out of INSTALL into scripts/README.txt version 1.2.41rc02 [November 22, 2009] Rebuilt the configure scripts with autoconf-2.65 version 1.2.41rc03 [November 25, 2009] Disabled the new pedantic warnings about deprecated function use and deprecated structure access unless the user defines PNG_PEDANTIC_WARNINGS. Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files. Removed "-DPNG_CONFIGURE_LIBPNG" from the makefiles and projects. version 1.2.41 [December 3, 2009] Updated the list of files and made some cosmetic changes in README.

(bug introduced in libpng-0.95, discovered by Evan Rouault) version 1.2.39beta03 [July 29, 2009] Relocated new png_64_bit_product() prototype into png.h Expanded the information about prototypes in the libpng style section of the documentation. Rebuilt configure scripts with autoconf-2.64. version 1.2.39beta04 [August 1, 2009] Replaced *.tar.lzma with *.txz in distribution.

2009-07-17Update to 1.2.38:wiz2-6/+6
version 1.2.38beta01 [June 17, 2009] Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR() multiple times and to specify the sample order in the tRNS chunk, because the ISO PNG specification has a typo in the tRNS table. Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism available for ignoring known chunks even when not saving unknown chunks. Adopted preference for consistent use of "#ifdef" and "#ifndef" versus "#if defined()" and "if !defined()" where possible. Added PNG_NO_HANDLE_AS_UNKNOWN in the PNG_LEGACY_SUPPORTED block of pngconf.h, and moved the various unknown chunk macro definitions outside of the PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED blocks. version 1.2.38rc01 [June 24, 2009] No changes. version 1.2.38rc02 [June 29, 2009] Added a reference to the libpng license in each source file. version 1.2.38rc03 [July 11, 2009] Revised references to the libpng license in pngconf.h and contrib/visupng source files.

2009-06-06Update to 1.2.37:wiz2-6/+6
version 1.2.37beta01 [May 14, 2009] Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36. The memset() was using "png_ptr->rowbytes" instead of "row_bytes", which the corresponding png_malloc() uses (Joe Drew). Clarified usage of sig_bit versus sig_bit_p in example.c (Vincent Torri) Updated some of the makefiles in the scripts directory (merged with those in libpng-1.4.0beta57). version 1.2.37beta02 [May 19, 2009] Fixed typo in libpng documentation (FILTER_AVE should be FILTER_AVG) Relocated misplaced #endif in pngwrite.c, sCAL chunk handler. Conditionally compile png_read_finish_row() which is not used by progressive readers. Added contrib/pngminim/preader to demonstrate building minimal progressive decoder, based on contrib/gregbook with embedded libpng and zlib. version 1.2.37beta03 [May 20, 2009] In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there is only one makefile in those directories, and revised the README files accordingly. Reformated sources in libpng style (3-space indentation, comment format) version 1.2.37rc01 [May 27, 2009] No changes. versions 1.2.37 and 1.0.45 [June 4, 2009] Reformatted several remaining "else statement;" and "if () statment;" into two lines. Added "#define PNG_NO_WRITE_SWAP" to contrib/pngminim/encoder/pngusr.h and "define PNG_NO_READ_SWAP" to decoder/pngusr.h and preader/pngusr.h Added sections about the git repository and our coding style to the documentation (merged from libpng-1.4.0beta62) Added a section about using png_get_io_ptr() in configure scripts to detect the presence of libpng.
2009-05-13Update to 1.2.36:wiz3-20/+20
version 1.2.36beta01 [February 28, 2009] Revised comments in png_set_read_fn() and png_set_write_fn(). Revised order of #ifdef's and indentation in png_debug definitions of png.h bug introduced in libpng-1.2.34. version 1.2.36beta02 [March 21, 2009] Use png_memset() after png_malloc() of big_row_buf when reading an interlaced file, to avoid a possible UMR. Undid recent revision of PNG_NO_STDIO version of png_write_flush(). Users having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined. Revised libpng*.txt documentation about use of png_write_flush(). Removed fflush() from pngtest.c. Added "#define PNG_NO_WRITE_FLUSH" to contrib/pngminim/encoder/pngusr.h version 1.2.36beta03 [March 27, 2009] Relocated misplaced PNG_1_0_X define in png.h that caused the prototype for png_set_strip_error_numbers() to be omitted from PNG_NO_ASSEMBLER_CODE builds. This bug was introduced in libpng-1.2.15beta4. Added a section on differences between 1.0.x and 1.2.x to libpng.3/libpng.txt version 1.2.36beta04 [April 5, 2009] Fixed potential memory leak of "new_name" in png_write_iCCP() (Ralph Giles) version 1.2.36beta05 [April 24, 2009] Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow application code writers to bypass the check for multiple inclusion of setjmp.h when they know that it is safe to ignore the situation. Made some cosmetic changes to whitespace in pngtest output. Renamed "user_chunk_data" to "my_user_chunk_data" in pngtest.c to suppress "shadowed declaration" warning from gcc-4.3.3. Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration" warning about a global "gamma" variable in math.h on some platforms. version 1.2.36rc01 [April 30, 2009] No changes. version 1.0.44 and 1.2.36 [May 7, 2009] No changes.
2009-03-20Simply and speed up buildlink3.mk files and processing.joerg1-13/+6
This changes the buildlink3.mk files to use an include guard for the recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS, BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of enter/exit marker, which can be used to reconstruct the tree and to determine first level includes. Avoiding := for large variables (BUILDLINK_ORDER) speeds up parse time as += has linear complexity. The include guard reduces system time by avoiding reading files over and over again. For complex packages this reduces both %user and %sys time to half of the former time.

version 1.2.34beta01 [November 27, 2008] Revised png_warning() to write its message on standard output by default when warning_fn is NULL. This was the behavior prior to libpng-1.2.9beta9. Fixed string vs pointer-to-string error in png_check_keyword(). Added png_check_cHRM_fixed() in png.c and moved checking from pngget.c, pngrutil.c, and pngwrite.c, and eliminated floating point cHRM checking. Added check for zero-area RGB cHRM triangle in png_check_cHRM_fixed(). In png_check_cHRM_fixed(), ensure white_y is > 0, and removed redundant check for all-zero coordinates that is detected by the triangle check. Revised png_warning() to write its message on standard output by default when warning_fn is NULL. version 1.2.34beta02 [November 28, 2008] Corrected off-by-one error in bKGD validity check in png_write_bKGD() and in png_handle_bKGD(). version 1.2.34beta03 [December 1, 2008] Revised bKGD validity check to use >= x instead of > x + 1 Merged with png_debug from libpng-1.4.0 to remove newlines. version 1.2.34beta04 [December 2, 2008] More merging with png_debug from libpng-1.4.0 to remove newlines. version 1.2.34beta05 [December 5, 2008] Removed redundant check for key==NULL before calling png_check_keyword() to ensure that new_key gets initialized and removed extra warning (Arvan Pritchard). version 1.2.34beta06 [December 9, 2008] In png_write_png(), respect the placement of the filler bytes in an earlier call to png_set_filler() (Jim Barry). version 1.2.34beta07 [December 9, 2008] Undid previous change and added PNG_TRANSFORM_STRIP_FILLER_BEFORE and PNG_TRANSFORM_STRIP_FILLER_AFTER conditionals and deprecated PNG_TRANSFORM_STRIP_FILLER (Jim Barry). version 1.0.42rc01, 1.2.34rc01 [December 11, 2008] No changes. version 1.0.42, 1.2.34 [December 18, 2008] No changes.
