+ Fixed several memory leaks in the TurboJPEG API library that
could occur if the library was built with certain compilers
and optimization levels.
+ The libjpeg-turbo memory manager will now honor the
max_memory_to_use structure member in jpeg_memory_mgr,
which can be set to the maximum amount of memory (in bytes)
that libjpeg-turbo should use during decompression or
multi-pass (including progressive) compression. This limit
can also be set using the JPEGMEM environment variable or
using the -maxmemory switch in cjpeg/djpeg/jpegtran.
+ TJBench will now run each benchmark for 1 second prior to
starting the timer, in order to improve the consistency of
the results. Furthermore, the -warmup option is now used to
specify the amount of warmup time rather than the number of
warmup iterations.
+ Fixed an error (short jump is out of range) that occurred
when assembling the 32-bit x86 SIMD extensions with NASM
versions prior to 2.04.
+ Fixed a regression introduced by 1.5 beta1[11] that prevented
the Java version of TJBench from outputting any reference images
(the -nowrite switch was accidentally enabled by default.)
libjpeg-turbo should now build and run with full AltiVec SIMD
acceleration on PowerPC-based AmigaOS 4 and OpenBSD systems.
- Update to version 1.5.2

OBS-URL: https://build.opensuse.org/package/show/graphics/libjpeg-turbo?expand=0&rev=69
+ Fix for PowerPC platforms lacking AltiVec instructions
+ Fix ABI problem with clang/llvm on aarch64.
+ Fancy upsampling is now supported when decompressing JPEG
images that use 4:4:0 (h1v2) chroma subsampling.
+ If merged upsampling isn't SIMD-accelerated but YCbCr-to-RGB
conversion is, then libjpeg-turbo will now disable merged
upsampling when decompressing YCbCr JPEG images into RGB
or extended RGB output images. This significantly speeds up
the decompression of 4:2:0 and 4:2:2 JPEGs on ARM platforms
if fancy upsampling is not used
(for example, if the -nosmooth option to djpeg is specified.)
+ The TurboJPEG API will now decompress 4:2:2 and 4:4:0 JPEG
images with 2x2 luminance sampling factors and 2x1 or 1x2
chrominance sampling factors.
+ Fixed an unsigned integer overflow in the libjpeg memory manager.
+ Fixed additional negative left shifts and other issues reported
by the GCC and Clang undefined behavior sanitizers when
attempting to decompress specially-crafted malformed JPEG
images. None of these issues posed a security threat, but
removing the warnings makes it easier to detect actual
security issues, should they arise in the future.
+ Fixed an out-of-bounds array reference, introduced by
1.4.902 and detected by the Clang undefined behavior sanitizer,
that could be triggered by a specially-crafted malformed
JPEG image with more than four components. Because the
out-of-bounds reference was still within the same structure,
it was not known to pose a security threat, but removing
the warning makes it easier to detect actual security issues,
should they arise in the future.

+ Fixed an issue whereby a malformed motion-JPEG frame could
cause the "fast path" of libjpeg-turbo's Huffman decoder to
read from uninitialized memory.
+ Added libjpeg-turbo version and build information to the global
string table of the libjpeg and TurboJPEG API libraries.
+ Fixed a couple of issues in the PPM reader that would cause
buffer overruns in cjpeg if one of the values in a binary
PPM/PGM input file exceeded the maximum value defined in the
file's header. libjpeg-turbo 1.4.2 already included a similar
fix for ASCII PPM/PGM files. Note that these issues were not
security bugs, since they were confined to the cjpeg program
and did not affect any of the libjpeg-turbo libraries.
+ Fixed an issue whereby attempting to decompress a JPEG file with
a corrupt header using the tjDecompressToYUV2() function would
cause the function to abort without returning an error and,
under certain circumstances, corrupt the stack. This only
occurred if tjDecompressToYUV2() was called prior to calling
tjDecompressHeader3(), or if the return value from
tjDecompressHeader3() was ignored (both cases represent
incorrect usage of the TurboJPEG API.)
+ The jpeg_stdio_src(), jpeg_mem_src(), jpeg_stdio_dest(),
and jpeg_mem_dest() functions in the libjpeg API will now
throw an error if a source/destination manager has already
been assigned to the compress or decompress object by a
different function or by the calling program.

* Fixed a bug whereby attempting to encode a progressive JPEG
with arithmetic entropy coding (by passing arguments of
-progressive -arithmetic to cjpeg or jpegtran, for instance)
would result in an error, "Requested feature was omitted at
compile time".
* Fixed a couple of issues whereby malformed JPEG images would
cause libjpeg-turbo to use uninitialized memory during
decompression.
* Fixed an error ("Buffer passed to JPEG library is too small")
that occurred when calling the TurboJPEG YUV encoding function
with a very small (< 5x5) source image, and added a unit test
to check for this error.
* etc. see ChangeLog.txt

by the reference implementation from IJG
- Remove libtool BuildRequires and autoreconf call

to break the ABI. And libturbojpeg.so is as a valid name as
libturbojpeg.so.0

* Fixed a 1-pixel error in row 0, column 21 of the luminance
plane generated by tjEncodeYUV().
* libjpeg-turbo's accelerated Huffman decoder previously
ignored unexpected markers found in the middle of the
JPEG data stream during decompression. It will now
hand off decoding of a particular block to the unaccelerated
Huffman decoder if an unexpected marker is found, so that
the unaccelerated Huffman decoder can generate an appropriate
warning.
* Fixed a bug in jpeg_read_coefficients() whereby it would
not initialize cinfo->image_width and cinfo->image_height
if libjpeg v7 or v8 emulation was enabled. This specifically
caused the jpegoptim program to fail if it was linked against
a version of libjpeg-turbo that was built with libjpeg v7 or
v8 emulation.
* Eliminated excessive I/O overhead that occurred when reading
BMP files in cjpeg.
