- switched the patter and input of $filter into the right places
- added pattern wildcard to MSYS_NT & CYGWIN_NT as they change with windows versions
- correctly identify MSYS2, even in an env like MINGW64
This doesn't affect most of the targets, but will help me sleep better at night knowing that future refactors won't break the legacy support.
Should have been included in https://github.com/facebook/zstd/pull/3943 but I noticed after that merged, so putting up a separate PR.
They are Linux-like environments under Windows and have all the tools needed to support staged installation and testing.
Beware: this only affects the make build system.
* Fixes zstd-dll build (https://github.com/facebook/zstd/issues/3492):
- Adds pool.o and threading.o dependency to the zstd-dll target
- Moves custom allocation functions into header to avoid needing to add dependency on common.o
- Adds test target for zstd-dll
- Adds github workflow that buildis zstd-dll
```
for f in $(find . \( -path ./.git -o -path ./tests/fuzz/corpora \) -prune -o -type f);
do
sed -i 's/Facebook, Inc\./Meta Platforms, Inc. and affiliates./' $f;
done
```
When creating a new `Makefile` target to build,
it's also necessary to update the `clean` target,
which purpose is to remove built targets when they are present.
This process is simple, but it's also easy to forget :
since there is a large distance between the position in the `Makefile` where the new built target is added,
and the place where the list of files to `clean` is defined.
Moreover, the list of files becomes pretty long over time,
hence it's difficult to visually ensure that all built targets are present there,
or that no old target (no longer produced) is no longer in the list
This PR tries to improve this process by adding a CLEAN variable.
Now, when a new built target is added to the `Makefile`,
it should preceded by :
```
CLEAN += newTarget
newTarget:
<TAB> ...recipe...
```
This new requirement is somewhat similar to `.PHONY: newTarget` for non-built targets.
This new method offers the advantage of locality :
there is no separate place in the file to maintain a list of files to clean.
This makes maintenance of `make clean` easier.
Add cli-tests to `make test`. This adds a `python3` dependency to `make
test`, but not `make check`. We could make this dependency optional by
skipping the tests if `python3` is not present.
* Extract out common portion of `lib/Makefile` into `lib/libzstd.mk`.
Most relevantly, the way we find library files.
* Use `lib/libzstd.mk` in the other Makefiles instead of repeating the
same code.
* Add a test `tests/test-variants.sh` that checks that the builds of
`make -C programs allVariants` are correct, and run it in Actions.
* Adds support for ASM files in the CMake build.
The Meson build is not updated because it lists every file in zstd,
and supports ASM off the bat, so the Huffman ASM commit will just add
the ASM file to the list.
The Visual Studios build is not updated because I'm not adding ASM
support to Visual Studios yet.
* Fix overflow correction when `windowLog < cycleLog`. Previously, we
got the correction wrong in this case, and our chain tables and binary
trees would be corrupted. Now, we work as long as `maxDist` is a power
of two, by adding `MAX(maxDist, cycleSize)` to our indices.
* When `ZSTD_WINDOW_OVERFLOW_CORRECT_FREQUENTLY` is defined to non-zero
run overflow correction as frequently as allowed without impacting
compression ratio.
* Enable `ZSTD_WINDOW_OVERFLOW_CORRECT_FREQUENTLY` in `fuzzer` and
`zstreamtest` as well as all the OSS-Fuzz fuzzers. This has a 5-10%
speed penalty at most, which seems reasonable.
* Switch to yearless copyright per FB policy
* Fix up SPDX-License-Identifier lines in `contrib/linux-kernel` sources
* Add zstd copyright/license header to the `contrib/linux-kernel` sources
* Update the `tests/test-license.py` to check for yearless copyright
* Improvements to `tests/test-license.py`
* Check `contrib/linux-kernel` in `tests/test-license.py`
this build works fine on all my systems,
but since to fail on CI environment.
Unclear why there is a difference.
This build test is not relevant anyway.
This commit leaves only the functions used by zstd_compress.c. All other
functions have been removed from the API. The ZSTDMT unit tests in
fuzzer.c and zstreamtest.c have been rewritten to use the ZSTD API. And
the --mt zstreamtest tests have been ripped out.
* All copyright lines now have -2020 instead of -present
* All copyright lines include "Facebook, Inc"
* All licenses are now standardized
The copyright in `threading.{h,c}` is not changed because it comes from
zstdmt.
The copyright and license of `divsufsort.{h,c}` is not changed.
* Removing symbols that are not being tested
* Removing symbols used in zstdcli, fileio, dibio and benchzstd
* Removing symbols used in zbuff and add test-zbuff to travis
* Removing remaining symbols and adding unit tests instead
* Removing symbols test entirely
* Make arugments optional and add --dict argument
* Removing accidental print statement
* Change to more likely scenario for dictionary compression benchmark
