As usual, the full release notes are found on Github: https://github.com/facebook/zstd/releases/tag/v1.4.5 Notable changes include: * Improved decompress performance on amd64 and arm (5-10% and 15-50%, respectively). * '--patch-from' zstd(1) CLI option, which provides something like a very fast version of bspatch(1) with slightly worse compression. See release notes. In this update, I dropped the 3-year old -O0 workaround for an LLVM ARM bug; the bug was fixed in LLVM SVN in 2017, but we didn't remove this workaround from our tree until now. MFC after: I won't, but feel free Relnotes: yes

Testing
|
|
=======
|
|
|
|
Zstandard CI testing is split up into three sections:
|
|
short, medium, and long tests.
|
|
|
|
Short Tests
|
|
-----------
|
|
Short tests run on CircleCI for new commits on every branch and pull request.
|
|
They consist of the following tests:
|
|
- Compilation on all supported targets (x86, x86_64, ARM, AArch64, PowerPC, and PowerPC64)
|
|
- Compilation on various versions of gcc, clang, and g++
|
|
- `tests/playTests.sh` on x86_64, without the tests on long data (CLI tests)
|
|
- Small tests (`tests/legacy.c`, `tests/longmatch.c`) on x64_64
|
|
|
|
Medium Tests
|
|
------------
|
|
Medium tests run on every commit and pull request to `dev` branch, on TravisCI.
|
|
They consist of the following tests:
|
|
- The following tests run with UBsan and Asan on x86_64 and x86, as well as with
|
|
Msan on x86_64
|
|
- `tests/playTests.sh --test-large-data`
|
|
- Fuzzer tests: `tests/fuzzer.c`, `tests/zstreamtest.c`, and `tests/decodecorpus.c`
|
|
- `tests/zstreamtest.c` under Tsan (streaming mode, including multithreaded mode)
|
|
- Valgrind Test (`make -C tests valgrindTest`) (testing CLI and fuzzer under valgrind)
|
|
- Fuzzer tests (see above) on ARM, AArch64, PowerPC, and PowerPC64
|
|
|
|
Long Tests
|
|
----------
|
|
Long tests run on all commits to `master` branch,
|
|
and once a day on the current version of `dev` branch,
|
|
on TravisCI.
|
|
They consist of the following tests:
|
|
- Entire test suite (including fuzzers and some other specialized tests) on:
|
|
- x86_64 and x86 with UBsan and Asan
|
|
- x86_64 with Msan
|
|
- ARM, AArch64, PowerPC, and PowerPC64
|
|
- Streaming mode fuzzer with Tsan (for the `zstdmt` testing)
|
|
- ZlibWrapper tests, including under valgrind
|
|
- Versions test (ensuring `zstd` can decode files from all previous versions)
|
|
- `pzstd` with asan and tsan, as well as in 32-bits mode
|
|
- Testing `zstd` with legacy mode off
|
|
- Testing `zbuff` (old streaming API)
|
|
- Entire test suite and make install on macOS
