* stdlib: implement `std::compression::zip` and `std::compression::deflate`
- C3 implementation of DEFLATE (RFC 1951) and ZIP archive handling.
- Support for reading and writing archives using STORE and DEFLATE
methods.
- Decompression supports both fixed and dynamic Huffman blocks.
- Compression using greedy LZ77 matching.
- Zero dependencies on libc.
- Stream-based entry reading and writing.
- Full unit test coverage.
NOTE: This is an initial implementation. Future improvements could be:
- Optimization of the LZ77 matching (lazy matching).
- Support for dynamic Huffman blocks in compression.
- ZIP64 support for large files/archives.
- Support for encryption and additional compression methods.
* optimizations+refactoring
deflate:
- replace linear search with hash-based match finding.
- implement support for dynamic Huffman blocks using the Package-Merge
algorithm.
- add streaming decompression.
- add buffered StreamBitReader.
zip:
- add ZIP64 support.
- add CP437 and UTF-8 filename encoding detection.
- add DOS date/time conversion and timestamp preservation.
- add ZipEntryReader for streaming entry reads.
- implement ZipArchive.extract and ZipArchive.recover helpers.
other:
- Add `set_modified_time` to std::io;
- Add benchmarks and a few more unit tests.
* zip: add archive comment support
add tests
* forgot to rename the benchmark :(
* detect utf8 names on weird zips
fix method not passed to open_writer
* another edge case where directory doesn't end with /
* testing utilities
- detect encrypted zip
- `ZipArchive.open_writer` default to DEFLATE
* fix zip64 creation, add tests
* fix ZIP header endianness for big-endian compatibility
Update ZipLFH, ZipCDH, ZipEOCD, Zip64EOCD, and Zip64Locator structs to
use little-endian bitstruct types from std::core::bitorder
* fix ZipEntryReader position tracking and seek logic ZIP_METHOD_STORE
added a test to track this
* add package-merge algorithm attribution
Thanks @konimarti
* standalone deflate_benchmark.c3 against `miniz`
* fix integer overflows, leaks and improve safety
* a few safety for 32-bit systems and tests
* deflate compress optimization
* improve match finding, hash updates, and buffer usage
* use ulong for zip offsets
* style changes (#18)
* style changes
* update tests
* style changes in `deflate.c3`
* fix typo
* Allocator first. Some changes to deflate to use `copy_to`
* Fix missing conversion on 32 bits.
* Fix deflate stream. Formatting. Prefer switch over if-elseif
* - Stream functions now use long/ulong rather than isz/usz for seek/available.
- `instream.seek` is replaced by `set_cursor` and `cursor`.
- `instream.available`, `cursor` etc are long/ulong rather than isz/usz to be correct on 32-bit.
* Update to constdef
* Fix test

* made the `test_hash_vector_internal` generic
* optimize `test_ct_intlog2` while still covering all 128 bit positions
* refactor whirlpool to reduce code bloat
replaced the fully unrolled round loop with a runtime loop, reducing
instruction count by 80k in `process_block` and yielding aprox 30%
performance boost due to improved cache locality.
* use compile-time arrays for `test_ct_intlog2`
* codepage: add single-byte code page support
Add std::encoding::codepage with a shared engine for converting between
single-byte code pages and UTF-8 using table-driven mappings.
Introduce generated tables and wrappers for several code pages[1] each
exposing encode/decode helpers built on a common CodePageTable
structure.
The mapping data is generated by cpgen[2] from the Unicode Consortium’s
published code page mapping files and follows the Unicode standard’s
interpretation of control characters (abstract characters) rather than
historical VGA glyph shapes.

* refactor(CI): Centralize test logic and fix Docker execution
This commit refactors the GitHub Actions workflow to improve
maintainability and correct a flaw in the Docker build.
- Ensures Docker based tests run *inside* the generated container, not
on the host. This also fixes environment isolation and user permission
errors.
- Centralizes all common test steps (examples, libs, unit tests, etc)
into a single, auto-detecting Bash script: `scripts/tools/ci_tests.sh`.
- Centralize all release artifact packaging into a single
`scripts/tools/package_build.sh`
- fixes using correct paths for test_suite_runner when running on
windows under bash.
- This significantly reduces YAML duplication, making `main.yml` more
readable and easier to maintain.
This one supersedes pull/2677, and includes the fixes for:
- fix openbsd and netbsd
- added win-llvm 21.1.8 and fixed CMakeLists.txt
- added full unit-tests and suite for build-msys2-mingw and
build-msys2-clang

* ci: run tests in temp dir to avoid workspace pollution

- now can be killed and the temp dirs are correctly cleaned up, and the
output is correct.
