DRC 55de9720 2019-10-24T01:50:35 AppVeyor: Use MinGW-builds instead of MSYS2 MinGW ... to avoid backward compatibility issues with GCC 4-6 MinGW toolchains. Apparently GCC 7+ MinGW toolchains introduce a link-time dependency with internal MinGW CRT functions that are meant to provide compatibility with Microsoft's Universal CRT (ucrt) library, but those internal functions are not available in GCC 4-6 MinGW toolchains. This made it impossible to use the official builds of libjpeg.a and libturbojpeg.a with GCC 4-6 MinGW toolchains (a fatal link error-- "undefined reference to '__imp___acrt_iob_func'"-- occurred.) This problem was not immediately apparent after switching to the MSYS2 implementation of MinGW (d6d7b539682abb50b04207abd21726573c0fb845) because, for a while, MSYS2 was still using GCC 5 and 6.

DRC ded5a504 2019-08-15T13:24:25 tjDecodeYUV*: Fix err if TJ inst used for prog dec If the TurboJPEG instance passed to tjDecodeYUV[Planes]() was previously used to decompress a progressive JPEG image, then we need to disable the progressive decompression parameters in the underlying libjpeg instance before calling jinit_master_decompress(). This commit also modifies the build system so that the "tjtest" target will test for this issue, and it corrects a previous oversight in the build system whereby tjbenchtest did not test progressive compression/decompression unless WITH_JAVA was true.

DRC 02f7bcdb 2019-08-13T16:03:48 Travis: Enable additional sanitizer tests - Re-purpose the non-SIMD test to test with MSan as well. - Re-purpose the ASan test to test with UBSan as well. - Use the default Travis build environment rather than specifying Ubuntu 14.04. I think I added 'dist: trusty' back when 14.04 was newer than the default, but now it's older than the default. - Enable verbose output for any unit tests that fail (so we can see the sanitizer output.)

DRC 875e873f 2019-07-11T17:05:15 tjutil.c: Fix compiler warning with Visual Studio Apparently windows.h includes stdlib.h, which defines the max() and min() macros, so we need to ensure that tjutil.h is included after that.
DRC 2a9e3bd7 2019-07-11T15:30:04 TurboJPEG: Properly handle gigapixel images Prevent several integer overflow issues and subsequent segfaults that occurred when attempting to compress or decompress gigapixel images with the TurboJPEG API: - Modify tjBufSize(), tjBufSizeYUV2(), and tjPlaneSizeYUV() to avoid integer overflow when computing the return values and to return an error if such an overflow is unavoidable. - Modify tjunittest to validate the above. - Modify tjCompress2(), tjEncodeYUVPlanes(), tjDecompress2(), and tjDecodeYUVPlanes() to avoid integer overflow when computing the row pointers in the 64-bit TurboJPEG C API. - Modify TJBench (both C and Java versions) to avoid overflowing the size argument to malloc()/new and to fail gracefully if such an overflow is unavoidable. In general, this allows gigapixel images to be accommodated by the 64-bit TurboJPEG C API when using automatic JPEG buffer (re)allocation. Such images cannot currently be accommodated without automatic JPEG buffer (re)allocation, due to the fact that tjAlloc() accepts a 32-bit integer argument (oops.) Such images cannot be accommodated in the TurboJPEG Java API due to the fact that Java always uses a signed 32-bit integer as an array index. Fixes #361
DRC f37b7c1f 2019-07-02T11:28:26 Build: Fix build/install with Xcode IDE Closes #355
Jonathan Wright 509c2680 2019-05-09T13:46:53 Use bias pattern for 4:4:0 (h1v2) fancy upsampling This commit modifies h1v2_fancy_upsample() so that it uses an ordered dither pattern, similar to that of h2v1_fancy_upsample(), rounding up or down the result for alternate pixels rather than always rounding down. This ensures that the decompression error pattern for a 4:4:0 JPEG image will be similar to the rotated decompression error pattern for a 4:2:2 JPEG image. Thus, the final result will be similar regardless of whether a 4:2:2 JPEG image is rotated or transposed before or after decompression. Closes #356
DRC ec5adb83 2019-05-18T17:58:50 Build/packaging: Support macOS package/DMG signing
DRC c8e52741 2019-05-09T09:11:09 Travis: Use xcode8.3 image xcode7.3 is based on El Capitan, which is EOL, and Homebrew no longer provides El Cap bottles (pre-compiled binaries.) Thus, Homebrew was trying to build GCC 5, YASM, and the other packages we need from source, which caused the Mac CI builds to time out. I tried goading Homebrew into installing GCC 5.5.0_2 and YASM 1.3.0_1, which still have El Cap bottles available, by using the URLs of those specific versions of the formulae (from the Homebrew GitHub repository) as package names. This failed, however, because 'brew bundle' converted the URLs to all lowercase. I then tried explicitly installing the old formulae by using 'brew install' with the aforementioned URLs (bypassing the Travis Homebrew addon), but Homebrew still tried to build all of the dependencies from source. Upgrading to Xcode 8.3.x necessitated regression testing the performance on iOS, but that proved less of a pain than figuring out how to install all of the old Homebrew bottles we needed. Also, this future-proofs the CI builds against the inevitable discontinuation of the xcode7.3 image. Note that Xcode 8.3.x improves iOS 64-bit decompression performance significantly relative to Xcode 7.2.x or 7.3.x. iOS 32-bit performance unfortunately regresses by as much as 5%, but it can't be helped (32-bit iOS apps are no longer supported on iOS 11+ anyhow, and the next major release of libjpeg-turbo will remove support for them as well.)
DRC 6399d0a6 2019-04-23T14:10:04 Fix code formatting/style issues ... ... including, but not limited to: - unused macros - private functions not marked as static - unprototyped global functions - variable shadowing (detected by various non-default GCC 8 warning options)
Chris Blume aa9db616 2019-04-15T17:55:47 x86 SIMD: Check for CPUID leaf 07H before using According to Intel's manual [1], "If a value entered for CPUID.EAX is higher than the maximum input value for basic or extended function for that processor then the data for the highest basic information leaf is returned." Right now, libjpeg-turbo doesn't first check that leaf 07H is supported before attempting to use it, so the ostensible AVX2 bit (Bit 05) of the CPUID result might actually be Bit 05 from a lower leaf. That bit might be set, even if the CPU doesn't support AVX2. This commit modifies the x86 and x86-64 SIMD feature detection code so that it first checks whether CPUID leaf 07H is supported before attempting to use it to check for AVX2 instruction support. DRC: This commit should fix https://bugzilla.mozilla.org/show_bug.cgi?id=1520760 However, I have not personally been able to reproduce that issue, despite using a Nehalem (pre-AVX2) CPU on which the maximum CPUID leaf has been limited via a BIOS setting. Closes #348 [1] "Intel® 64 and IA-32 Architectures Software Developer's Manual, Volume 2 (2A, 2B, 2C & 2D): Instruction Set Reference, A-Z", https://software.intel.com/sites/default/files/managed/a4/60/325383-sdm-vol-2abcd.pdf, page 3-192.

DRC d3a3a73f 2019-04-10T14:28:47 jdhuff.c: Silence UBSan signed int overflow error Some pathological test images have been created that can cause s to overflow or underflow the signed int data type during decompression. This is technically undefined behavior according to the C spec, although every modern implementation I'm aware of will treat the signed int as a 2's complement unsigned int, thus causing the value to wrap around to INT_MIN if it exceeds INT_MAX. This commit simply makes that behavior explicit in order to shut up UBSan. At least when building for x86-64 or i386 using Clang or GCC, this commit does not change the compiler-generated assembly code at all. The code that triggered this error has existed in the libjpeg code base for at least 20 years (and probably much longer), so the fact that it hasn't produced a user-visible problem in all of that time strongly suggests that UBSan is being overly pedantic here. But if someone can cough up a platform that doesn't wrap around to INT_MIN when 1 is added to INT_MAX, then I'll happily change my opinion. Fixes #347

Chris Blume b46af82c 2019-02-12T17:35:10 ARMv7 NEON: #ifdef unused funcs/vars w/ -mfpu=neon When simd/arm/jsimd.c is compiled with __ARM_NEON__ defined (which will be the case if -mfpu=neon is passed to the compiler), the parse_proc_cpuinfo() and check_feature() functions and the bufsize variable are unused and thus need to be #ifdef'ed out in order to avoid compiler warnings. Note that the bufsize variable was already #ifdef'ed out on Linux but not on Android due to lack of parentheses (&& takes precedence over ||.) Closes #331

This issue caused the debuginfo build under RHEL 8 (which is apparently now enabled by default-- regardless of whether the RPM actually contains debug info, but that's another matter) to fail with: RPM build errors: File listed twice: /opt/libjpeg-turbo/lib64/pkgconfig/libjpeg.pc File listed twice: /opt/libjpeg-turbo/lib64/pkgconfig/libturbojpeg.pc
DRC 4b67db4d 2019-02-13T15:20:34 rpm.spec.in: Fix doc packaging issues w/ RHEL 7+ On RHEL 7 and later (not sure exactly whether this is a product of the newer RPM release or something distro-specific), macros are lazily expanded, so we need to set _docdir using %global (which expands at definition time) and prior to _prefix and _datarootdir (which affect _defaultdocdir.) Otherwise, _docdir is set to a subdirectory of /opt/libjpeg-turbo/share/doc or /opt/libjpeg-turbo/doc. The former (which happens on RHEL 7) leads to incorrect documentation packaging (the docs should be packaged under /usr/share/doc per Red Hat standards), and the latter (which happens on RHEL 8) leads to an RPM build error.

DRC 2d0b675a 2019-01-25T16:46:02 Build: Fix install of static build w/ VStudio IDE Unfortunately, this hack is necessary because: - install(TARGETS, ...) doesn't support the RENAME option. - We can't modify OUTPUT_NAME for the "-static" targets without breaking the regression tests. - ${CMAKE_CFG_INTDIR} doesn't seem to work properly in an install() command.

DRC 90e2d7f3 2019-01-23T08:27:45 LICENSE.md: Clarifications RE: BSD & zlib licenses Including the license templates was confusing to some, since it made it appear as if the copyright year and author were unspecified for the libjpeg-turbo source. Thus, rather than include the zlib License template, link to that template on opensource.org. For the Modified BSD License, include a roll-up of copyright years and authors, since the terms of that license require the text of it to be included in product documentation for binary distributions without accompanying source code.

DRC 479501b0 2019-01-21T13:57:55 TurboJPEG: Decompress 4:4:4 JPEGs with unusual SFs Normally, 4:4:4 JPEGs have horizontal x vertical luminance & chrominance sampling factors of 1x1. However, it is technically legal to create 4:4:4 JPEGs with sampling factors of 2x1, 1x2, 3x1, or 1x3, since the sums of the products of those sampling factors are still <= 10. The libjpeg API correctly decodes such images, so the TurboJPEG API should as well. Fixes #323

luzpaz 43c58ff9 2018-07-31T21:59:16 Correct various typos in code comments Found via `codespell -q 3` Closes #263
DRC 574f3a77 2018-07-27T11:44:46 Clarify Android Windows build instructions (must add .exe to CMAKE_C_COMPILER) Addresses a concern raised in #245, #260
DRC ad6c3161 2018-07-25T11:03:20 Bump revision to 2.0.0
DRC 8d95be3a 2018-07-24T21:16:00 Build: Don't use @rpath with OS X 10.4 builds @rpath is only supported with 10.5 and later deployment targets. libjpeg-turbo hasn't supported 10.4 "Tiger" since prior to 1.4, but I still sometimes use the 10.4 SDK to test PowerPC code in a Snow Leopard VM.
DRC a6289526 2018-07-24T18:36:51 Fix JPEG spec references per ISO/ITU-T suggestions - When referring to specific clauses, annexes, tables, and figures, a "timed reference" (a reference that includes the year) must be used in order to avoid confusion. - "CCITT" = "ITU-T" - Replace ambiguous "JPEG spec" with the specific document number.
Even Rouault 9ab569e6 2018-07-20T18:04:15 Fix int overflow when decompr. corrupt prog. JPEG No discernible performance regression Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9447 Credit to OSS Fuzz Closes #259
DRC 9c78a04d 2018-07-20T17:21:36 cjpeg: Fix OOB read caused by malformed 8-bit BMP ... in which one or more of the color indices is out of range for the number of palette entries. Fix partly borrowed from jpeg-9c. This commit also adopts Guido's JERR_PPM_OUTOFRANGE enum value in lieu of our project-specific JERR_PPM_TOOLARGE enum value. Fixes #258
DRC 0fa7850a 2018-07-20T11:30:04 Build: Preserve CMake exe suffix from cmd line Normally the value of CMAKE_EXECUTABLE_SUFFIX is clobbered by project(). This allows for specifying an executable suffix of .html with Emscripten builds, which causes Emscripten to build standalone HTML versions of the libjpeg-turbo test programs.
DRC 0c8eb5b4 2018-07-19T17:01:42 Honor CMake exe suffix when inst. static builds This specifically allows an Emscripten (WASM) static build (for which CMAKE_EXECUTABLE_SUFFIX=.js) to be properly installed.
DRC 84893085 2018-07-10T15:06:46 README.ijg: Clarification regarding JPEG 2000/XR The sentence: "Indeed, one of the original reasons for developing this free software was to help force convergence on common, interoperable format standards for JPEG files." might be seen to imply that JPEG 2000 and JPEG XR are not interoperable with themselves, although it is certainly the case that those formats are not interoperable with each other, nor with ITU T.81 | ISO/IEC 10918. They are also certainly not as common as ITU T.81 | ISO/IEC 10918, and (as an example) popular web browsers will not display JPEG 2000 files. The sentence in question was originally referring to proprietary, non-standard formats and was meant to provide historical context. libjpeg was originally released prior to the adoption of JFIF as an official standard, so it encouraged adoption of JFIF as a de facto standard by providing, under a business-friendly free software license, a library for reading and writing images in that format.
DRC f4b8a5cf 2018-07-02T11:42:06 BUILDING.md: Correct iOS/Android examples toolchain.cmake should be created in the build directory, so the scripts need to cd to that directory before generating that file. Closes #254
DRC 6d8caa9f 2018-06-29T12:45:57 Build: Detect whether compiler supports DSPr2 This is basically the same test that was performed in acinclude.m4 in the old autotools-based build system. It was not ported to the CMake-based build system because I previously had no way of testing a non-DSPr2 build environment. Fixes #248
Darrell Walisser 398c1e9a 2018-06-16T18:31:35 Fix jpeg_skip_scanlines() segfault w/merged upsamp Fixes NULL pointer reference when decompressing 4:2:2 or 4:2:0 JPEG images with cinfo.do_fancy_upsampling = FALSE. Closes #244
DRC 26f10929 2018-06-24T17:31:15 Fix infinite loop in partial image decompression ... caused by using certain specific combinations of jpeg_skip_scanlines() and jpeg_read_scanlines() calls with progressive, vertically-subsampled JPEG images. Fixes #237
DRC 43e84cff 2018-06-12T20:27:00 tjLoadImage(): Fix FPE triggered by malformed BMP In rdbmp.c, it is necessary to guard against 32-bit overflow/wraparound when allocating the row buffer, because since BMP files have 32-bit width and height fields, the value of biWidth can be up to 4294967295. Specifically, if biWidth is 1073741824 and cinfo->input_components = 4, then the samplesperrow argument in alloc_sarray() would wrap around to 0, and a division by zero error would occur at line 458 in jmemmgr.c. If biWidth is set to a higher value, then samplesperrow would wrap around to a small number, which would likely cause a buffer overflow (this has not been tested or verified.)
DRC 696e754e 2018-06-12T18:49:37 TurboJPEG: Handle JERR_BMP*,JERR_PPM* error codes ... in tjLoadImage()/tjSaveImage(). These error codes require an add-on message table, and if it isn't initialized, then format_message() produces "Bogus message code XXXX" instead.
