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.
. 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.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
buildlink2.mk files back into the main trunk. This provides sufficient
buildlink2 infrastructure to start merging other packages from the
buildlink2 branch that have already been converted to use the buildlink2
framework.
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.
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.
