Many build scripts, ports and other third-party add-ons that are

Examples include the Vcpkg build system (including the libpng port)
and the Meson build definitions (including the libpng definition).
I am, therefore, relicensing our CI scripts once more, as the sole

from/to such projects. Hopefully, this one last license will stick.

From the libpng licensing point of view, the build projects, the build
scripts, the test scripts, the CI verification scripts, et cetera, have
not traditionally been part of libpng proper, although some of these,
including the CMake-based build, have been released under the libpng
license.
Considering how the CMake build grew as a result of many contributions
from many contributing authors over a long time, one may argue that it
almost became an individual piece of software in its own right.
Moving on, everything CMake-related shall be placed in the subdirectory
scripts/cmake/ (except, of course, the main CMakeLists.txt). Moreover,
contributing authors shall be acknowledged in scripts/cmake/AUTHORS.md.
Please see scripts/cmake/README.md for more information.

Relax pngtest-all message testing

Previously the 'make check' test pngtest-all looked for given messages
at EOL. The match failed with Windows/MSYS2 because of the Windows
<cr><lf> line endings output by pngtest. This changes the test to look
for the message anywhere in a line; this might give false matches but
the specific messages being searched for are not likely to cause this
problem.

The test always failed on systems with no support for zlib
inflateValidate and on systems where the png_set_option setting was

tests/pngtest-all: detect failures add tests
...
This change is only verifiable in configure builds; cmake only executes
the basic test.
The previous version of tests/pngtest-all only returned the status code
of the final test. Apparently it could never fail. This adds checking
of all return status codes.
The change also adds a basic approach for regression testing with PNGs
that should fail a test; --strict ensures that PNGs which are valid do
not start to be reported as erroneous, this is the inverse.
At present the code (minimal traditional Bourne shell) only tests the
palette index checking code, a potentially important check if apps rely
on it.
The changes have been tested using the configure build both with a
regression which causes the libpng checking to cease to work and with a
corrected (reverted regression). The regression test verifies that the
intended check works as expected.

Do not build unused Adler32 code
...
This removes the default build of an undocumented feature to disable
Adler32 checksums on those systems where it was the default.
The PR is motived by github #187 however it fixes a much more general
problem (#187 is limited to an issue where libpng "crashes" on some
manufacturer systems). The fix is based on a suggestion by @sgowdev who
is the originator of the issue.
When libpng disables the checking of Adler32 checksums it does so by an
undocumented and therefore possibly unsupported call to a zlib function
which does not exist in some versions of zlib.
Fortunately libpng only does this if the caller of libpng explicitly
asks for it to happen. Unfortunately the call to the undocumented
function is still in the compiled and built libpng and this means that
on some systems (as identified in #187 ) libpng can fail to load or maybe
even crash.
The libpng authors are currently unaware of any program or system that
uses this feature and none has been identified by the contributors to
In this fix an option is added to *enable* the code so that by default
the code is *disabled* - this is a simple generalization of the
suggestion by @sgowdev.
BENEFITS: the problem is eliminated, users of the functionality, if any,
are idenfified, the functionality can be implemented correctly in the
future or it can be removed. Hardly anyone complains.
COSTS: someone will complain that they have to enable an option in a
libpng build to use a feature that never worked consistently in the
first place.
This patch has been tested both with the option enabled and with it
disabled via pngusr.dfa. Tests, checks pass with cmake and configure,
make distcheck passes on configure.

Regression test for off-by-one palette check error
...
This adds a file to regression-test the previously introduced off-by-one
error in the check on read for a colormapped PNG with an out-of-range
index (equal or greater than the length of the PLTE).
Previous tests covered all cases except the 8-bit palette case; the
"small" test file contains the "bad" entry at index 254, not 255 so it
passes even if the final byte is not checked. The new file has the
erroneous entry in the last byte.

Fix unused platform check and configuration for macOS
...
In a similar manner as zlib (https://github.com/madler/zlib/pull/895 ),
libpng contains a header configuration that's no longer valid and
hasn't been exercised for the macOS target.
- The target OS conditional macros are misused. Specifically
`TARGET_OS_MAC` covers all Apple targets, including iOS, and it
should not be checked with `#if defined` as they would always be
defined (to either 1 or 0) on Apple platforms.
- `#include <fp.h>` no longer works for the macOS target and results
in a compilation failure. macOS ships all required functions in
`math.h`, and clients should use `math.h` instead.
This problem has not been noticed until a recent extension in clang
(https://github.com/llvm/llvm-project/pull/74676 ) exposed the issue
and broke libpng builds on Apple platforms. The failure can be
reproduced now by adding `#include <TargetConditionals.h>` before the
block.

write palette check corrections
...
The write palette check is off-by-one when checking the maximum palette
index against the number of entries however, because of the
implementation, the simple correction would fail if no palette check had
been performed (for example for a non-palette image). This corrects
both errors so that the code outputs a warning (but not an error) if a
user of libpng writes an image with a PLTE which is one entry short.
The write palette check can be turned off on colour type 3 images
(colour mapping images) but this is done by setting the 'maximum'
palette index in the image to (-1). The ammended code works because it
only executes for paletted images, it is dependent on palette checks
being compiled in and they will always be checked unless the stored
'max' value is less than 0.

Palette index checking fixes
...
The palette index checking function is called by default but only if
some *other* transformation is happening. This makes the 'get palette
max' public API disfunctional (sometimes it works, sometimes it returns
0) and causes the supposed default behaviour of checking the palette
index only to work sometimes. It works in pngtest, it doesn't work in
pngcp.
The check in pngread also has an off-by-one error; the number recorded
is the highest index found so it should be checked to ensure that it is
less than the palette length but it was checked for being greater.
The pull request includes a set of 8 files which all have the full range
of possible indices including one (the highest) which is invalid because
the PLTE chunk is one short of the maximum for each bit depth.

pngcp: remove GNU setjmp warning workround

Prior versons of the GCC warned about the 'dest' parameter of
contrib/tools/pngcp.c not being volatile, which isn't necessary because
it isn't modified. This removes the GCC specific fixup.
The function which calls setjmp, cppng() also relied on undefined
behavior because it assigned the result of setjmp() to a variable; this
is not one of the four uses of setjmp permitted by ANSI-C. This passes
the result previously returned by longjmp via (struct display). It's
very very unlikely that any compiler could have got the code wrong but
it is technically undefined.

cmake: Enable the libpng framework build by default on Apple systems
...
The PNG_FRAMEWORK option used to be off by default. It was possible to
turn it on, regardless of the underlying operating system, but doing so
outside of an Apple OS broke the libpng build.
PNG_FRAMEWORK is now on by default, conditionally defined on Apple
systems only, and it is ignored (without breaking the build) elsewhere.
Other minor changes have also been applied.

configure: allow to disable building of tools and test

This PR adds two set of options to the configure script:
--enable-png-tests/--disable-png-tests
and
--enable-png-tools/--disable-png-tools
By using this feature, a user will be allowed to build only library if
needed, which will be useful on platforms not able to build the tools
and/or the tests.
This PR leaves the existing behaviour as default setting, by building
both the tools and the tests if the options are not used.
CMakeLists.txt already supports this feature with the options PNG_TESTS
and PNG_EXECUTABLES. After this commit, Autotools will provide the same
feature.

arm: Add a compile-time assertion about PNG_ARM_NEON_CHECK_SUPPORTED
...
Following up on the previous commit by Martin Storsjö:
If the availability of ARM Neon is not only known at compile time,
but also expected by the compiler's target architecture, there should
be no further need for a run-time check. In fact, such a check would
be counter-productive.

cmake: Default to PNG_ARM_NEON=off for arm targets
...
This matches the configure script - unless the user has requested
anything, no hardware optimizations are autoenabled.
Defaulting to "check" is brittle (that configuration is deprecated
and poorly supported) - and for configurations where it would
make sense (where NEON isn't universally enabled in the compiler)
it didn't end up setting ARM_NEON_OPT to 1 in pnglibconf.h anyway.
This fixes default builds with cmake for iOS and Windows on armv7,
where NEON is universally available (but there's no runtime check
implemented) - but actually using NEON on this architecture
requires explicitly opting in to it when configuring, just like
with the configure script.

scripts: Remove the support for "install" targets from all makefiles
...
In most of the legacy makefiles (with only a few notable exceptions
such as makefile.linux), the "install" targets have been broken since
libpng-1.5.0beta01. Specifically, the "install-shared" targets produced
incorrect library names, due to a missing symbol in the definition of
the LIBSOREL macro.
Rather than correcting this long-standing and long-untested error, we
decided to remove the support for "make install" altogether, from all
legacy makefiles. Further use of "make install", "make install-static"
or "make install-shared" will fail with an error message.
Going forward, the only tested and supported manners to install libpng
shall be the conventional build and install procedures driven by the
configure script or by the CMake file.

Revert "Remove second call to write_eXIf"

The second call to png_write_eXIf should not have been removed.
The first call to png_write_eXIf is for writing the eXIf chunk that is
positioned before IDAT, while the second call is for writing the eXIf
chunk that is positioned after IDAT.
TODO:
Implement a correct fix which consists in ensuring that there are no
eXIf chunks simultaneously before and after IDAT.

cmake: Fix the build on Unix with source files checked out on Windows
...
The issue is that, by default, Git for Windows checks out text files
with CRLF line endings. This is a problem for awk, which is expecting
Unix-style LF line endings. When cloning on Windows and attempting to
compile on WSL, Mingw or Cygwin, there may be an error from awk.
The fix is to leverage CMake's ability to configure a file and perform
EOL conversions. We copy the awk scripts from the source directory to
the build directory. This portable method ensures they have LF endings,
and the build logic is updated to use the build directory version.
Intentionally avoiding .gitattributes to avoid setting precedent.

I got a warning while compiling under Ubuntu 18.04 and gcc 7.4:
"__BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
Quote from the Linux Programmer's Manual:
"To allow code that requires _BSD_SOURCE in glibc 2.19 and earlier and
_DEFAULT_SOURCE in glibc 2.20 and later to compile without warnings,
define both _BSD_SOURCE and _DEFAULT_SOURCE."

Fix memory leak if eXIf has incorrect crc
...
Problem description:
Imagine a bitstream with an eXIf data segment that has invalid CRC.
If png_crc_finish() fails at line 2090, info_ptr->eXIf_buf is not freed
(despite the free_me setting at line 2062) because png_free_data() is
not called. png_read_info() is actually looping several time over the
png_eXIf chunk, calling png_handle_eXIf() several time in a row without
freeing the buffer.
This patch fixes the problem by leaving info_ptr's content in a clean
state in case of failure, as it is done at line 2084.

* On Linux, use both clang and gcc.
* On macOS, use clang only, with and without Xcode.
For AppVeyor CI, add a build matrix as follows:
* On Windows, use Microsoft Visual Studio 2019 on x86, x64 and arm64.
* Also on Windows, use MSYS2 on x86 and x64.

arm: Partially revert "Fix a memory leak in the riffled palette [...]"
...
The memory leak remains fixed, but the associated refactoring is
being reverted. Moving the initialization of the riffled palette
from png_do_read_transformations to png_init_palette_transformations
has caused a regression in some of the test programs.
Although png_init_palette_transformations is the proper place to
perform this initialization, and the test programs are technically
incorrect to fail, we are still undoing that refactoring for the
time being.

Remove top-level const from function-scope variables
...
As per the const correctness rules, top-level const-ness of data
in automatic scopes does not propagate outside of these scopes
(unlike const-ness at lower levels, such as pointers to const data).
Previously, const was used liberally, but inconsistently across the
libpng codebase. Using const wherever applicable is not incorrect.
However, _consistent_ use of const is difficult to maintain in such
conditions.
In conclusion, we shall continue to use const only where doing so is
strictly necessary:
1. If a function guarantees that it will not modify an argument
passed by pointer, the corresponding function parameter should be
a pointer-to-const (const T *).
2. Static data should not be modified, therefore it should be const.

[libpng16] Removed one of the GCC-7.1.0 'strict-overflow' warnings that
...
result when integers appear on both sides of a compare. Worked around the
others by forcing the strict-overflow setting in the relevant functions to
a level where they are not reported.
Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
the space.
Worked around some C-style casts from (void*) because g++ 5.4.0 objects
to them.
Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
overflow' check that is on by default with -Wall -Wextra.

Remove 'defined' within macro
...
This removes the use of a macro containing the pre-processor 'defined'
operator. It is unclear whether this is valid; a macro which
"generates" 'defined' is not permitted, but the use of the work
"generates" within the C90 standard seems to imply more than simple
substitution of an expression itself containing a well-formed defined
operation.

[libpng16] Quieted about 100 warnings from clang-3.8 in pngtrans.c, pngread.c,

319c9852bf
Unsigned overflow
...
Remove all currently detected cases of unsigned overflow. Detection is
runtime, so test case dependent. The changes to pngvalid.c eliminate
spurious and probably invalid tests with one while loop exception.
Apart from that and the change to the dependence on the intended
unsigned overflow in pngtrans.c the changes are limited to altering the
meme for an unsigned 'x' from:
while (x-- > 0)
to
for (; x > 0; --x)
This works because, in all cases, the control variable is not used in
the loop. The 'while' meme was, at one time, warn'ed by GCC so it is
probably a good change, for some weird religious value of good.

[libpng16] pngfix zero-length IDAT fix
...
When an input file contains a zero length IDAT and pngfix is not applying the
IDAT rechunking (--max) option pngfix will go into a loop writing the zero
length IDAT for ever.
This is a fairly minor issue for interactive use; zero length IDAT is very rare,
the problem is obvious (pngfix hangs) and the fix (use --max, or --max=4096
etc), while not obvious, is easy.
For non-interactive use, e.g. trying to automatically repair a PNG that cannot
be read by libpng, there are security consequences:
1) pngfix hangs. This may permit a DoS attack.
2) When the --out option is used pngfix will just keep writing. This is a very
likely DoS scenario.

[libpng16] Reject oversized iCCP profile length
...
The code now validates the ICC profile length against the user chunk limit
before the buffer is allocated, as opposed to doing it while the buffer is read.
This removes the potential to consume virtual address space with a carefully
crafted ICC profile; only an issue on 32-bit systems where a valid profile can
be up to 2^32-4 bytes in length. libpng never writes beyond the application
supplied limit, but previously it did allocate a buffer of the size specified in
the profile header. The exploitability of this is almost zero; the address
space is released as soon as the PNG read completes.
Also clean up PNG_DEBUG compile of pngtest.c.

pngcp bug fixes

The fixed size buffer for the file name being processed could have a byte
written beyond the end; a bug where the test was updated without changing the
size of the buffer. This commit reduces the buffer to the system maximum.
png_getrowbytes could, in theory, return 0; probably only if there is a bug in
libpng but the code now checks.

pngcp: tool to copy PNG files
...
This adds pngcp to the build together with a pngcp.dfa configuration test; the
test revealed some configuration bugs which are fixed by corrections to the
_SUPPORTED macros.
pngcp builds on all tested configurations and a number of bugs have been fixed
to make this happen relative to the version in libpng 1.7 contrib/examples.
pngcp.dfa will have to be different for 1.7 but pngcp.c should work fine (not
yet tested). pngcp itself is still missing a usage message; this is a
preliminary version, although since it behaves the same way as 'cp' most unoids
shouldn't have a problem using it correctly.

projects/vstudio: enthusiastic warnings
...
The commit removes the three compile warning options from the individual project
files into the zlib.props globals (this should probably be renamed in 1.7). It
increases the warning level from 4 to All and adds a list of the warnings which
need to be turned off. This is semi-documentary; the intent is to tell users of
libpng which warnings have been examined and judged non-fixable at present.
The warning about structure padding *IS* fixable, but it is a signficant change
(moving structure members around). It is currently partially fixed in 1.7, but
only partially.

Change image size checks
...
This covers the case where PNG_IMAGE_BUFFER_SIZE can overflow in the application
as a result of the application using an increased 'row_stride'; previously
png_image_finish_read only checked for overflow on the base calculation of
components. (I.e. it checked for overflow of a 32-bit number on the total
number of pixel components in the output format, not the possibly padded row
length and not the number of bytes, which for linear formats is twice the number
of components.)

The code no longer gives up/fails on invalid PNG data, it just skips it (with
error messages). The code no longer fails on PNG files with data beyond IEND.
Options exist to use png_read_png (reading the whole image, not by row) and, in
that case, to apply any of the supported transforms. This makes for more
realistic testing; the decoded data actually gets used in a meaningful fashion.

Relax limit checks on gamma values.
...
As suggested in the comments gamma values outside the range currently permitted
by png_set_alpha_mode are useful for HDR data encoding. These values are
already permitted by png_set_gamma so it is reasonable caution to extend the
png_set_alpha_mode range as HDR imaging systems are starting to emerge.

PNG_IMAGE_PNG_SIZE_MAX error correction
...
The macro underreported the size (by up to 512 bytes) of an 8-bit non-color
palette based memory format because it failed to take into account that the
memory palette has to be expanded to full RGB when it is written to PNG.
This is not likely to be a serious bug because the macro is new, the memory
format in question is likely to be rarely used and the result of an undersized
buffer fails in a safe way.

Simplified API: write-to-memory, overflow handling
...
This implements an API and provides a number of assist macros to allow an
application which uses the simplified API write to bypass stdio and write
directly to memory.
It also includes some warnings (png.h) and some check code to detect *possible*
overflow in the ROW_STRIDE and simplified image SIZE macros. This disallows
image width/height/format that *might* overflow. A quiet API change that limits
in-memory image size (uncompressed) to less that 4GByte and image row size
(stride) to less than 2GByte.

Fix undefined behavior in pngvalid.c

Undefined because (png_byte) << shift is undefined if it changes the signed bit

png_get_uint_32 and png_get_uint_16 handle this.
Bug reported by David Drysdale as a result of reports from UBSAN in clang 3.8.
This changes pngvalid to use BE random numbers; this used to produce errors but
these should not be fixed as a result of the previous changes.

Fix inconsistent handling of invalid zlib data
...
In libpng 1.6 zlib initialization was changed to use the window size in the zlib
stream, not a fixed value. This causes some invalid images, ones where CINFO is
too large, to display 'correctly' if the rest of the data is valid. This
provides a work-round for zlib versions where the error arises (ones that
support the API change to use the window size in the stream).

rowbytes check correction
...
The old code incorrectly calculated the output rowbytes when the
application decreased either the number of channels or the bit depth (or
both) in a user transform. This was safe; libpng overallocated buffer
space (potentially by quite a lot; up to 4 times the amount required)
but, from 1.5.4 on, resulted in a png_error.

New test PNG files incorporated into make check

tests/pngstest-* are changed so that the new test files are divided into 8
groups by gamma and alpha channel. This makes each test take just under 5
seconds on a moderately up-to-date x86_64 system using libpng16 (test times are
somewhat variable under libpng17 at present because of the lack of optimization
in some gamma processing paths.)
These tests have considerably better code and pixel-value coverage than
contrib/pngsuite however coverage is still incomplete.

...
This updates libpng16 with all the test changes from libpng17,
including changes to pngvalid.c to ensure that the original,
distributed, version of contrib/visupng/cexcept.h can be used.
pngvalid contains the correction to the use of SAVE/STORE_
UNKNOWN_CHUNKS; a bug revealed by changes in libpng 1.7. More
tests contain the --strict option to detect warnings and the
pngvalid-standard test has been corrected so that it does not
turn on progresive-read (there is a separate test which does
that.)
Some signed/unsigned fixes have been made.

[libpng16] Fixed array size calculations to avoid warnings. At various points
...
in the code the number of elements in an array is calculated using
sizeof. This generates a compile time constant of type (size_t) which
is then typically assigned to an (unsigned int) or (int). Some versions
of GCC on 64-bit systems warn about the apparent narrowing, even though
the same compiler does apparently generate the correct, in-range,
numeric constant. This adds appropriate, safe, casts to make the
warnings go away.

[libpng15] Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code

[libpng15] Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
...
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
now that png_ptr->buffer is inaccessible to applications, the special
handling is no longer useful.
Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).

longer necessary to gain iTXt support), as a signal that the user has
been building previous versions with PNG_iTXt_SUPPORTED as well.
