Clarify that a stream containing too many Huffman weights is invalid
List of updates : https://github.com/Cyan4973/xxHash/releases/tag/v0.8.2 This is also a preparation task before taking care of #3819
…_3.5 [cmake] Require CMake version 3.5 or newer
Linux started providing intptr_t in <linux/types.h> so we no longer need to define it here. https://lkml.kernel.org/r/ed66b9e4-1fb7-45be-9bb9-d4bc291c691f@p183
ZSTD_resetDStream() is deprecated and replaced by ZSTD_DCtx_reset(). This removes deprecation warnings from the kernel build. This change is a no-op, see the docs suggesting this replacement. https://github.com/facebook/zstd/blob/fcbf2fde9ac7ce1562c7b3a394350e764bcb580f/lib/zstd.h#L2655-L2663
We only use this constant when `DEBUGLEVEL>=2`, but we get -Werror=pedantic errors for empty translation units, so still define it except in kernel environments. Backport from the kernel: https://lore.kernel.org/lkml/20230616144400.172683-1-ben.dooks@codethink.co.uk/
gcc in the linux kernel was not unrolling the inner loops of the Huffman decoder, which was destroying decoding performance. The compiler was generating crazy code with all sorts of branches. I suspect because of Spectre mitigations, but I'm not certain. Once the loops were manually unrolled, performance was restored. Additionally, when gcc couldn't prove that the variable left shift in the 4X2 decode loop wasn't greater than 63, it inserted checks to verify it. To fix this, mask `entry.nbBits & 0x3F`, which allows gcc to eliete this check. This is a no op, because `entry.nbBits` is guaranteed to be less than 64. Lastly, introduce the `HUF_DISABLE_FAST_DECODE` macro to disable the fast C loops for Issue #3762. So if even after this change, there is a performance regression, users can opt-out at compile time.
* Rename `ilimit` to `ilowest` and set it equal to `src` instead of `src + 6 + 8`. This is safe because the fast decoding loops guarantee to never read below `ilowest` already. This allows the fast decoder to run for at least two more iterations, because it consumes at most 7 bytes per iteration. * Continue the fast loop all the way until the number of safe iterations is 0. Initially, I thought that when it got towards the end, the computation of how many iterations of safe might become expensive. But it ends up being slower to have to decode each of the 4 streams individually, which makes sense. This drastically speeds up the Huffman decoder on the `github` dataset for the issue raised in #3762, measured with `zstd -b1e1r github/`. | Decoder | Speed before | Speed after | |----------|--------------|-------------| | Fallback | 477 MB/s | 477 MB/s | | Fast C | 384 MB/s | 492 MB/s | | Assembly | 385 MB/s | 501 MB/s | We can also look at the speed delta for different block sizes of silesia using `zstd -b1e1r silesia.tar -B#`. | Decoder | -B1K ∆ | -B2K ∆ | -B4K ∆ | -B8K ∆ | -B16K ∆ | -B32K ∆ | -B64K ∆ | -B128K ∆ | |----------|--------|--------|--------|--------|---------|---------|---------|----------| | Fast C | +11.2% | +8.2% | +6.1% | +4.4% | +2.7% | +1.5% | +0.6% | +0.2% | | Assembly | +12.5% | +9.0% | +6.2% | +3.6% | +1.5% | +0.7% | +0.2% | +0.03% |
`HUF_DecompressFastArgs_init()` was adding 0 to NULL. Fix it by exiting early for empty outputs. This is no change in behavior, because the function was already exiting 0 in this case, just slightly later.
update xxhash library to v0.8.2
This PR introduces no functional changes. It attempts to change all
macros currently using `{ }` or some variant of that to to
`do { } while (0)`, and introduces trailing `;` where necessary.
There were no bugs found during this migration.
The bug in Visual Studios warning on this has been fixed since VS2015.
Additionally, we have several instances of `do { } while (0)` which have
been present for several releases, so we don't have to worry about
breaking peoples builds.
Fixes Issue #3830.
…hts as 0 is invalid
The patch adds a validation to ensure that the last field, which is reserved, must be all-zeroes in ZSTD_decodeSeqHeaders. This prevents potential corruption from going undetected. Fixes an issue where corrupted input could lead to undefined behavior due to improper validation of reserved bits. Signed-off-by: aimuz <mr.imuz@gmail.com>
Move offload API params into ZSTD_CCtx_params
12.4 is EOL as of the end of December 2023, and pkg installation will start failing some time after that so remove those jobs now.
Update FreeBSD CI: drop 12.4 (nearly EOL)
Clang 16 (which is the system compiler in FreeBSD 14.0) no longer allows K&R function definitions. Formatting of the changes matches current zlib.
If the relevant allocation returns NULL, ZSTD_createCDict_advanced_internal() will return NULL. But ZSTD_createCDict_advanced2() doesn't check for this and attempts to use the returned pointer anyway, which leads to a segfault.

when requested CBlockSize is too low, bound it to the minimum instead of returning an error.
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`.
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).
* fuzzing and bugfixes for magicless format * reset dctx before each decompression * do not memcmp empty buffers * nit: decompressor errata
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.

[](https://renovatebot.com) This PR contains the following updates: | Package | Type | Update | Change | |---|---|---|---| | [com_github_facebook_zstd](https://togithub.com/facebook/zstd) | http_archive | patch | `v1.5.5` -> `v1.5.6` | --- ### Release Notes <details> <summary>facebook/zstd (com_github_facebook_zstd)</summary> ### [`v1.5.6`](https://togithub.com/facebook/zstd/releases/tag/v1.5.6): Zstandard v1.5.6 - Chrome Edition [Compare Source](https://togithub.com/facebook/zstd/compare/v1.5.5-kernel...v1.5.6) This release highlights the deployment of Google [Chrome 123](https://developer.chrome.com/blog/new-in-chrome-123), introducing `zstd-encoding` for Web traffic, introduced as a preferable option for compression of dynamic contents. With limited web server support for `zstd-encoding` due to its novelty, we are launching an updated Zstandard version to facilitate broader adoption. ##### New stable parameter `ZSTD_c_targetCBlockSize` Using `zstd` compression for large documents over the Internet, data is segmented into smaller blocks of up to 128 KB, for incremental updates. This is crucial for applications like Chrome that process parts of documents as they arrive. However, on slow or congested networks, there can be some brief unresponsiveness in the middle of a block transmission, delaying update. To mitigate such scenarios, `libzstd` introduces the new parameter `ZSTD_c_targetCBlockSize`, enabling the division of blocks into even smaller segments to enhance initial byte delivery speed. Activating this feature incurs a cost, both runtime (equivalent to -2% speed at level 8) and a slight compression efficiency decrease (<0.1%), but offers some interesting latency reduction, notably beneficial in areas with less powerful network infrastructure. ##### Granular binary size selection `libzstd` provides build customization, including options to compile only the compression or decompression modules, minimizing binary size. Enhanced in `v1.5.6` ([source](https://togithub.com/facebook/zstd/tree/dev/lib#modular-build)), it now allows for even finer control by enabling selective inclusion or exclusion of specific components within these modules. This advancement aids applications needing precise binary size management. ##### Miscellaneous Enhancements This release includes various minor enhancements and bug fixes to enhance user experience. Key updates include an expanded list of recognized compressed file suffixes for the `--exclude-compressed` flag, improving efficiency by skipping presumed incompressible content. Furthermore, compatibility has been broadened to include additional chipsets (`sparc64`, `ARM64EC`, `risc-v`) and operating systems (`QNX`, `AIX`, `Solaris`, `HP-UX`). #### Change Log api: Promote `ZSTD_c_targetCBlockSize` to Stable API by [@​felixhandte](https://togithub.com/felixhandte) api: new experimental `ZSTD_d_maxBlockSize` parameter, to reduce streaming decompression memory, by [@​terrelln](https://togithub.com/terrelln) perf: improve performance of param `ZSTD_c_targetCBlockSize`, by [@​Cyan4973](https://togithub.com/Cyan4973) perf: improved compression of arrays of integers at high compression, by [@​Cyan4973](https://togithub.com/Cyan4973) lib: reduce binary size with selective built-time exclusion, by [@​felixhandte](https://togithub.com/felixhandte) lib: improved huffman speed on small data and linux kernel, by [@​terrelln](https://togithub.com/terrelln) lib: accept dictionaries with partial literal tables, by [@​terrelln](https://togithub.com/terrelln) lib: fix CCtx size estimation with external sequence producer, by [@​embg](https://togithub.com/embg) lib: fix corner case decoder behaviors, by [@​Cyan4973](https://togithub.com/Cyan4973) and [@​aimuz](https://togithub.com/aimuz) lib: fix zdict prototype mismatch in static_only mode, by [@​ldv-alt](https://togithub.com/ldv-alt) lib: fix several bugs in magicless-format decoding, by [@​embg](https://togithub.com/embg) cli: add common compressed file types to `--exclude-compressed` by [@​daniellerozenblit](https://togithub.com/daniellerozenblit) (requested by [@​dcog989](https://togithub.com/dcog989)) cli: fix mixing `-c` and `-o` commands with `--rm`, by [@​Cyan4973](https://togithub.com/Cyan4973) cli: fix erroneous exclusion of hidden files with `--output-dir-mirror` by [@​felixhandte](https://togithub.com/felixhandte) cli: improved time accuracy on BSD, by [@​felixhandte](https://togithub.com/felixhandte) cli: better errors on argument parsing, by [@​KapJI](https://togithub.com/KapJI) tests: better compatibility with older versions of `grep`, by [@​Cyan4973](https://togithub.com/Cyan4973) tests: lorem ipsum generator as default content generator, by [@​Cyan4973](https://togithub.com/Cyan4973) build: cmake improvements by [@​terrelln](https://togithub.com/terrelln), [@​sighingnow](https://togithub.com/sighingnow), [@​gjasny](https://togithub.com/gjasny), [@​JohanMabille](https://togithub.com/JohanMabille), [@​Saverio976](https://togithub.com/Saverio976), [@​gruenich](https://togithub.com/gruenich), [@​teo-tsirpanis](https://togithub.com/teo-tsirpanis) build: bazel support, by [@​jondo2010](https://togithub.com/jondo2010) build: fix cross-compiling for AArch64 with lld by [@​jcelerier](https://togithub.com/jcelerier) build: fix Apple platform compatibility, by [@​nidhijaju](https://togithub.com/nidhijaju) build: fix Visual 2012 and lower compatibility, by [@​Cyan4973](https://togithub.com/Cyan4973) build: improve win32 support, by [@​DimitriPapadopoulos](https://togithub.com/DimitriPapadopoulos) build: better C90 compliance for zlibWrapper, by [@​emaste](https://togithub.com/emaste) port: make: fat binaries on macos, by [@​mredig](https://togithub.com/mredig) port: ARM64EC compatibility for Windows, by [@​dunhor](https://togithub.com/dunhor) port: QNX support by [@​klausholstjacobsen](https://togithub.com/klausholstjacobsen) port: MSYS2 and Cygwin makefile installation and test support, by [@​QBos07](https://togithub.com/QBos07) port: risc-v support validation in CI, by [@​Cyan4973](https://togithub.com/Cyan4973) port: sparc64 support validation in CI, by [@​Cyan4973](https://togithub.com/Cyan4973) port: AIX compatibility, by [@​likema](https://togithub.com/likema) port: HP-UX compatibility, by [@​likema](https://togithub.com/likema) doc: Improved specification accuracy, by [@​elasota](https://togithub.com/elasota) bug: Fix and deprecate ZSTD_generateSequences ([#​3981](https://togithub.com/facebook/zstd/issues/3981)), by [@​terrelln](https://togithub.com/terrelln) #### Full change list (auto-generated) -
