* 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

* stdlib: optimize math::next_power_of_2 to O(1) using hardware CLZ
- updated DString.reserve to use this
* bit smearing

- Printing stacktrace uses its own temp allocator.
- `@pool` no longer takes an argument.
- `Allocator` interface removes `mark` and `reset`.
- DynamicArenaAllocator has changed init function.
- Added `BackedArenaAllocator` which is allocated to a fixed size, then allocates on the backing allocator and supports mark/reset.
- `string::new_from_*` changed to `string::from_*`.
- `String.to_utf16_copy` and related changed to `String.to_utf16`.
- `String.to_utf16_tcopy` and related changed to `String.to_temp_utf16`
- `mem::temp_new` changed to `mem::tnew`.
- `mem::temp_alloc` and related changed to `mem::talloc`.
- `mem::temp_new_array` changed to `mem::temp_array`.
Upgrade of mingw in CI. Fix problems using reflection on interface types #1203. Improved debug information on defer. $foreach doesn't create an implicit syntactic scope.
Error if `@if` depends on `@if`. Updated Linux stacktrace. Fix of default argument stacktrace. Allow linking libraries directly by file path. Improve inlining warning messages. Added `index_of_char_from`. Compiler crash using enum nameof from different module #1205. Removed unused fields in find_msvc. Use vswhere to find msvc. Update tests for LLVM 19
* make conv::char32_to_utf8_unsafe() return the number of bytes it wrote
add tests for DString
fix pointer arithmetic in DString.insert_at
