Fix & fuzz ZSTD_generateSequences
2024-03-21Fix & fuzz ZSTD_generateSequencesNick Terrell
This function was seriously flawed: * It didn't do output bounds checks * It produced invalid sequences when an uncompressed or RLE block was emitted * It produced invalid sequences when the block splitter was enabled * It produced invalid sequences when ZSTD_c_targetCBlockSize was enabled I've attempted to fix these issues, but this function is just a bad idea, so I've marked it as deprecated and unsafe. We should replace it with `ZSTD_extractSequences()` which operates on a compressed frame.

2024-03-18Fail on errors when building fuzzersYonatan Komornik
Fails on errors when building fuzzers with `fuzz.py` (adds `Werror`). Currently allows `declaration-after-statement`, `c++-compat` and `deprecated` as they are abundant in code (some fixes to `declaration-after-statement` are presented in this commit).
2024-03-18Fix bugs in simple decompression fuzzer (#3978)Yonatan Komornik
Fixes 2 issue in `simple_decompress.c`: 1. Wrong type used for storing the results of `ZSTD_findDecompressedSize` resulting in never matching to `ZSTD_CONTENTSIZE_ERROR` or `ZSTD_CONTENTSIZE_UNKNOWN`. 2. Experimental API is used (`ZSTD_findDecompressedSize`) without defining `ZSTD_STATIC_LINKING_ONLY`.

2024-03-18[cmake] Emit warnings for contradictory build settingsNick Terrell
Document that the `ZSTD_BUILD_{SHARED,STATIC}` take precedence over `BUILD_SHARED_LIBS` when exactly one is ON. Thanks to @teo-tsirpanis for pointing out the potentially confusing behavior.
2024-03-18pzstd: use c++14 without conditionsAlexander Kanavin
Doing this check with a direct c++ snippet is prone to portability problems: - \043 is not portable between shells: dash expands it to #, bash does not; - using # directly works with make 4.3 but does not with make 4.2. Let's just use the c++ version that covers both the code and the gtest.

2024-03-18[cmake] Fix up PR #3716Nick Terrell
* Make a variable `PublicHeaders` for Zstd's public headers * Add `PublicHeaders` to `Headers`, which was missing * Only export `${LIBRARY_DIR}` publicly, not `common/` * Switch the `target_include_directories()` to `INTERFACE` because zstd uses relative includes internally, so doesn't need any include directories to build * Switch installation to use the `PublicHeaders` variable, and test that the right headers are installed

2024-03-14[cmake] Always create libzstd targetNick Terrell
If both `ZSTD_BUILD_SHARED` and `ZSTD_BUILD_STATIC` are set, then cmake exports the libraries `libzstd_shared` and `libzstd_static` only. It does not export `libzstd`, which is only exported when exactly one of `ZSTD_BUILD_SHARED` and `ZSTD_BUILD_STATIC` is set. This PR exports `libzstd` in that case, based on the value of the standard CMake variable [`BUILD_SHARED_LIBS`](https://cmake.org/cmake/help/latest/variable/BUILD_SHARED_LIBS.html). This ensures that `libzstd` can always be used to refer to the exported zstd library, since the build errors if neither `ZSTD_BUILD_SHARED` nor `ZSTD_BUILD_STATIC` are set. I tested all the possible combinations of `ZSTD_BUILD_SHARED`, `ZSTD_BUILD_STATIC`, and `BUILD_SHARED_LIBS` and they always worked as expected: * If only exactly one of `ZSTD_BUILD_SHARED` and `ZSTD_BUILD_STATIC` is set, that is used as `libzstd`. * Otherwise, libzstd is set based on `BUILD_SHARED_LIBS`. Fixes #3859.

2024-03-13Promote `ZSTD_c_targetCBlockSize` Parameter to Stable APIW. Felix Handte
This feature has demonstrated itself to be useful in web compression and we want to encourage other folks to use it. But we currently make it difficult to do so since it's locked away in the experimental API. The API itself is really straightforward and I think it's fine to commit to maintaining support / compatibility for this API even if in the future the underlying implementation may continue to evolve. Note that this commit changes its enum name and also its numeric value. Users who respected the instructions of using the experimental API should be fine with both of these changes since they should only have referred to it by the. Conceivably someone could have done bad feature detection of this capability by doing `#ifdef ZSTD_c_targetCBlockSize` which will now return false since it's no longer a macro... but I think that's an acceptable hypothetical breakage.

2024-03-13Use `utimensat()` on FreeBSDW. Felix Handte
FreeBSD only claims to support POSIX 2001 [0]. But they do in fact support `utimensat()`. This adds a specific check to opt them in to using it. This value was selected by consulting [1]. See discussion on #3952. Further addresses #3748.

2024-03-13[asm][aarch64] Mark that BTI and PAC are supportedNick Terrell
Mark that `huf_decompress_amd64.S` supports BTI and PAC, which it trivially does because it is empty for aarch64. The issue only requested BTI markings, but it also makes sense to mark PAC, which is the only other feature. Also run add a test for this mode to the ARM64 QEMU test. Before this PR it warns on `huf_decompress_amd64.S`, after it doesn't. Fixes Issue #3841.
