When an error occurs in BMK_isSuccessful_runOutcome, the code
previously skipped the call to BMK_freeTimedFnState(tfs),
leaking the allocated tfs object.
Fiexed by calling BMK_freeTimedFnState(tfs) before goto _cleanOut.
- Split monolithic 235-line CMakeLists.txt into focused modules
- Main file reduced to 78 lines with clear section organization
- Created 5 specialized modules:
* ZstdVersion.cmake - CMake policies and version management
* ZstdOptions.cmake - Build options and platform configuration
* ZstdDependencies.cmake - External dependency management
* ZstdBuild.cmake - Build targets and validation
* ZstdPackage.cmake - Package configuration generation
Benefits:
- Improved readability and maintainability
- Better separation of concerns
- Easier debugging and modification
- Preserved 100% backward compatibility
- All existing build options and targets unchanged
The refactored build system passes all tests and maintains
identical functionality while being much easier to understand
and maintain.
- Create new .github/workflows/cmake-tests.yml with all cmake-related jobs
- Move cmake-build-and-test-check, cmake-source-directory-with-spaces, and cmake-visual-2022 jobs
- Remove cmake tests from dev-short-tests.yml to improve organization
- Maintain same trigger conditions and test configurations
- Add dedicated concurrency group for cmake tests
This separation allows cmake tests to run independently and makes
the CI configuration more modular and easier to maintain.
The FUZZ_malloc_rand() function was incorrectly always returning NULL for
zero-size allocations. The random offset generated by
FUZZ_dataProducer_int32Range() was not being added to the pointer variable,
causing the function to always return (void *)0.
In main, resources were freed on the success path but not in the error path.
This change ensures all allocated resources are released before returning.
Building lz4 as root was causing `make clean` to fail with permission
errors.
We used to have to install lz4 from source back in Ubuntu 14.04, but
nowadays the installed lz4 is fine. Get rid of ancient helpers and
cruft!
There was no memory barrier between writing and reading `done`, which
would allow reordering to cause races. With so little data to handle
after each job completes, we might as well just join.
Previously, parallel_compression would only handle each job's results
after ALL jobs were successfully queued. This caused all src/dst
buffers to remain in memory until then!
It also polled to check whether a job completed, which is racy without
any memory barrier.
Now, we flush results as a side effect of completing a job. Completed
frames are placed in an ordered linked-list, and any eligible frames
are flushed. This may be zero or multiple frames, depending on the
order in which jobs finish.
This design also makes it simple to support streaming input, so that
is now available. Just pass `-` as the filename, and stdin/stdout will
be used for I/O.
Some of these examples are intended to be parallel, and don't make
sense to link against single-threaded libzstd.
The filename of mt and nomt libzstd are identical, so it's still
possible to link against the single-threaded one, just harder.
The pkg-config file has License variable that allows you to set the license for
the software. This sets 'BSD-3-Clause OR GPL-2.0-only' to License.

After the update to MacOS 15.4, the dynamic loader dyld treats duplicated LC_RPATH as an error.
The `FLAGS` variable already contains `LDFLAGS`, thus using both `FLAGS` and `LDFLAGS`
duplicates all `LDFLAGS`, including `-Wl,rpath` parameters.
The duplicate LC_RPATH causes this kind of errors:
```
dyld[29361]: Library not loaded: @loader_path/../lib/libzstd.1.dylib
Referenced from: <7131C877-3CF0-33AC-AA05-257BA4FDD770> /Users/foobar/...
Reason: tried: '/Users/foobar/..../lib/libzstd.1.dylib' (duplicate LC_RPATH '/usr/mypath.../lib')
```
