The one that isn't pinned is the OSS-Fuzz builder and runner. They don't
offer tagged releases. I could pin to the current master commit, but I'm not
sure how desirable that is.
`ZSTD_LIB_MINIFY` broke in 8bf699aa59.
This commit fixes the macro and the static library shrinks from ~600K to 324K
with ZSTD_LIB_MINIFY set.
Fixes#3066.
It seems like with the deletion of Travis CI we didn't successfully transfer the
version compatibility test. Attempt to enable the version compatibility test.
There are a couple of oddities here. We don't attempt to build e.g.
contrib, because that doesn't seem to work at the moment. Also notice
that each command is its own step. This happens because github actions
runs in powershell, which doesn't seem to let you abort on the first
failure.
As mentioned in
https://github.com/facebook/zstd/pull/3252#issuecomment-1251733791 ,
this patch adds a CI job that builds and installs libzstd on the job
runner, and then compiles a sample binary linking against the installed
library; the needed build flags are passed by invoking pkg-config.
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.
Tests that libzstd.so doesn't have the exec-stack bit set using
readelf. If the stack is marked executable systemd will refuse
to link against zstd. We now test that it isn't set on every PR.
Adds a test for PR #2857
Fixes Issue #2865
Switch to a macro `ZSTD_FALLTHROUGH;` instead of a comment. On supported
compilers this uses an attribute, otherwise it becomes a comment.
This is necessary to be compatible with clang's `-Wfall-through`, and
gcc's `-Wfall-through=2` which don't support comments. Without this the
linux build emits a bunch of warnings.
Also add a test to CI to ensure that we don't regress.
* 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.
