2021-10-15zlib-ng: Remove flag `-fno-semantic-interposition`lineage-18.1zclkkk
* runs well on my Arch laptop but fails on our infra :( For now simply apply this workaround from @ zclkkk. Change-Id: Ia164112b8f262f6e3f1bf3714fb4f639069a29ce
2021-04-18Remove GitHub Actions workflowsDanny Lin
This is an Android-specific fork, so we don't care about these workflows.
2021-04-18Add zconf.h for Android buildsDanny Lin
2021-04-18Add zlib_bench from Chromium zlibDanny Lin
This tool is very helpful for comparing different implementations of zlib.
2021-04-18Port zlib-ng to the Android platformDanny Lin
- Add Soong blueprint - Add CRC32 fixes - Add NDK mappings All changes were based on the Android fork of Chromium zlib. As reported by simpleperf, a considerable amount of CPU time is spent decompressing Android binary XML resources when opening and closing activities in Settings. Because of this, some binary XMLs from framework-res.apk have been used for zlib_bench testing. zlib-ng is significantly faster than vanilla zlib and Chromium zlib (with optimizations enabled) in terms of compression. 64-bit benchmarks with zlib_bench64 on Android: Compression: +------------------------------------------+------+---------------+---------+-------+ | File | zlib | Chromium zlib | zlib-ng | Unit | +------------------------------------------+------+---------------+---------+-------+ | res/anim/activity_open_enter.xml | 10.4 | 16 | 25.1 | MiB/s | | res/anim/activity_close_enter.xml | 9.3 | 15.5 | 21.1 | MiB/s | | res/transition/move.xml | 9.7 | 16.4 | 21.6 | MiB/s | | res/drawable/stat_sys_battery_charge.xml | 13.3 | 22.4 | 33.2 | MiB/s | +------------------------------------------+------+---------------+---------+-------+ The gains are less significant for decompression, and Chromium zlib is generally slighty faster in this case. However, zlib-ng still tends to be faster than vanilla zlib: Decompression: +------------------------------------------+-------+---------------+---------+-------+ | File | zlib | Chromium zlib | zlib-ng | Unit | +------------------------------------------+-------+---------------+---------+-------+ | res/anim/activity_open_enter.xml | 136.8 | 150.6 | 153.2 | MiB/s | | res/anim/activity_close_enter.xml | 125.7 | 133.5 | 123 | MiB/s | | res/transition/move.xml | 120.6 | 129.9 | 124.4 | MiB/s | | res/drawable/stat_sys_battery_charge.xml | 194.6 | 222.1 | 217.3 | MiB/s | +------------------------------------------+-------+---------------+---------+-------+ In combination with enabling -O3 for libpng, zlib-ng speeds up screenshot saving by 16% on redfin (Cortex-A55 + Cortex-A76) as compared to vanilla zlib. While Android is likely to be decompressing much more data than it compresses, zlib-ng's significantly faster compression should be a worthwhile tradeoff for its deficiencies in decompression speed. zlib versions used for benchmarks: Vanilla zlib: [1] (Chromium zlib with optimizations disabled) Chromium zlib: [2] with all optimizations enabled zlib-ng: [3] with Android porting changes All zlib variants were built with -O3, as per commit [4].

2021-03-20Restore hash_head != 0 checksIlya Leoshkevich
Commit bc5915e2dec7 ("Fixed unsigned integer overflow ASAN error when hash_head > s->strstart.") removed hash_head != 0 checks in fast, medium and slow deflate, because it improved performance [1]. Unfortunately, the attached test started failing after that. Apparently, as the comments suggest, the code implicitly relies on matches with the beginning of the window being skipped. So restore the check. [1] https://github.com/zlib-ng/zlib-ng/pull/772#issuecomment-710760300

2021-03-18Add a CMake macro for simple test executablesIlya Leoshkevich
6 tests use the same pattern: build a binary linked with zlib-ng and run it. At the moment this requires 5 near-identical lines of CMake code, leading to proliferation of copy-paste. Introduce a macro to get rid of it.

2021-03-17Fix block_open handling in deflate_quick()Ilya Leoshkevich
The attached test fails with "inflate() failed", because the deflate stream that it produces ends up being corrupted. Bisect points to the commit e7bb6db09a18 ("Replace hash_bits, hash_size and hash_mask with defines."), but it's most likely a coincidence. In any case, the reason is that if we happen to simultaneously exhaust all the buffers (in, out and bi), we return finish_started without writing the end of block symbol, which will never happen afterwards. Fix by adding another check to the tricky condition: if we are in the middle of a block, return need_more instead of finish_started.

2021-03-16Fix defining HAVE_SYS_SDT_H with CMakeIlya Leoshkevich iii@linux.ibm.com
DFLTCC probe points are never activated when compiling with CMake. This is because check_include_file() only sets an internal CMake variable, but not a C define [1]. Fix as the link suggests - by adding an explicit add_definitions. [1] https://cmake.org/pipermail/cmake/2015-June/060830.html

2021-03-16Fix bi_valid handling in deflate_quick()Ilya Leoshkevich iii@linux.ibm.com
The attached test started failing after commit ad89d5131b29 ("Don't write end of last block when returning finish_started."): either with "bi_buf not flushed" message in debug builds, or by producing corrupted output in release builds. The problem is that we must not return finish_started when bi_buf is not empty, because the bits there will be lost. Fix by checking that bi_valid is not 0.
