# Changelog ## [1.2.2](https://github.com/zip-rs/zip2/compare/v1.2.1...v1.2.2) - 2024-05-09 ### <!-- 1 -->🐛 Bug Fixes - Failed to clear "writing_raw" before finishing a symlink, leading to dropped extra fields ### <!-- 4 -->⚡ Performance - Use boxed slice for archive comment, since it can't be concatenated - Optimize for the fact that false signatures can't overlap with real ones ## [1.2.1](https://github.com/zip-rs/zip2/compare/v1.2.0...v1.2.1) - 2024-05-06 ### <!-- 1 -->🐛 Bug Fixes - Prevent panic when trying to read a file with an unsupported compression method - Prevent panic after reading an invalid LZMA file - Make `Stored` the default compression method if `Deflated` isn't available, so that zip files are readable by as much software as possible - version_needed was wrong when e.g. cfg(bzip2) but current file wasn't bzip2 ([#100](https://github.com/zip-rs/zip2/pull/100)) - file paths shouldn't start with slashes ([#102](https://github.com/zip-rs/zip2/pull/102)) ### <!-- 2 -->🚜 Refactor - Overhaul `impl Arbitrary for FileOptions` - Remove unused `atomic` module ## [1.2.0](https://github.com/zip-rs/zip2/compare/v1.1.4...v1.2.0) - 2024-05-06 ### <!-- 0 -->🚀 Features - Add method `decompressed_size()` so non-recursive ZIP bombs can be detected ### <!-- 2 -->🚜 Refactor - Make `ZipWriter::finish()` consume the `ZipWriter` ### <!-- 7 -->⚙️ Miscellaneous Tasks - Use panic! rather than abort to ensure the fuzz harness can process the failure - Update fuzz_write to use replace_with - Remove a drop that can no longer be explicit - Add `#![allow(unexpected_cfgs)]` in nightly ## [1.1.4](https://github.com/zip-rs/zip2/compare/v1.1.3...v1.1.4) - 2024-05-04 ### <!-- 1 -->🐛 Bug Fixes - Build was failing with bzip2 enabled - use is_dir in more places where Windows paths might be handled incorrectly ### <!-- 4 -->⚡ Performance - Quick filter for paths that contain "/../" or "/./" or start with "./" or "../" - Fast handling for separator-free paths - Speed up logic if main separator isn't '/' - Drop `normalized_components` slightly sooner when not using it - Speed up `path_to_string` in cases where the path is already in the proper format ### <!-- 7 -->⚙️ Miscellaneous Tasks - Refactor: can short-circuit handling of paths that start with MAIN_SEPARATOR, no matter what MAIN_SEPARATOR is - Bug fix: non-canonical path detection when MAIN_SEPARATOR is not slash or occurs twice in a row - Bug fix: must recreate if . or .. is a path element - Bug fix ### <!-- 9 -->◀️ Revert - [#58](https://github.com/zip-rs/zip2/pull/58) (partial): `bzip2-rs` can't replace `bzip2` because it's decompress-only ## [1.1.3](https://github.com/zip-rs/zip2/compare/v1.1.2...v1.1.3) - 2024-04-30 ### <!-- 1 -->🐛 Bug Fixes - Rare bug where find_and_parse would give up prematurely on detecting a false end-of-CDR header ## [1.1.2](https://github.com/Pr0methean/zip/compare/v1.1.1...v1.1.2) - 2024-04-28 ### <!-- 1 -->🐛 Bug Fixes - Alignment was previously handled incorrectly ([#33](https://github.com/Pr0methean/zip/pull/33)) ### <!-- 2 -->🚜 Refactor - deprecate `deflate-miniz` feature since it's now equivalent to `deflate` ([#35](https://github.com/Pr0methean/zip/pull/35)) ## [1.1.1] ### Added - `index_for_name`, `index_for_path`, `name_for_index`: get the index of a file given its path or vice-versa, without initializing metadata from the local-file header or needing to mutably borrow the `ZipArchive`. - `add_symlink_from_path`, `shallow_copy_file_from_path`, `deep_copy_file_from_path`, `raw_copy_file_to_path`: copy a file or create a symlink using `AsRef<Path>` arguments ### Changed - `add_directory_from_path` and `start_file_from_path` are no longer deprecated, and they now normalize `..` as well as `.`. ## [1.1.0] ### Added - Support for decoding LZMA. ### Changed - Eliminated a custom `AtomicU64` type by replacing it with `OnceLock` in the only place it's used. - `FileOptions` now has the subtype `SimpleFileOptions` which implements `Copy` but has no extra data. ## [1.0.1] ### Changed - The published package on crates.io no longer includes the tests or examples. ## [1.0.0] ### Changed - Now uses boxed slices rather than `String` or `Vec` for metadata fields that aren't likely to grow. ## [0.11.0] ### Added - Support for `DEFLATE64` (decompression only). - Support for Zopfli compression levels up to `i64::MAX`. ### Changed - `InvalidPassword` is now a kind of `ZipError` to eliminate the need for nested `Result` structs. - Updated dependencies. ## [0.10.3] ### Changed - Updated dependencies. - MSRV increased to `1.67`. ### Fixed - Fixed some rare bugs that could cause panics when trying to read an invalid ZIP file or using an incorrect password. ## [0.10.2] ### Changed - Where possible, methods are now `const`. This improves performance, especially when reading. ## [0.10.1] ### Changed - Date and time conversion methods now return `DateTimeRangeError` rather than `()` on error. ## [0.10.0] ### Changed - Replaces the `flush_on_finish_file` parameter of `ZipWriter::new` and `ZipWriter::Append` with a `set_flush_on_finish_file` method. ### Fixed - Fixes build errors that occur when all default features are disabled. - Fixes more cases of a bug when ZIP64 magic bytes occur in filenames. ## [0.9.2] ### Added - `zlib-ng` for fast Deflate compression. This is now the default for compression levels 0-9. - `chrono` to convert zip::DateTime to and from chrono::NaiveDateTime ## [0.9.1] ### Added - Zopfli for aggressive Deflate compression. ## [0.9.0] ### Added - `flush_on_finish_file` parameter for `ZipWriter`. ## [0.8.3] ### Changed - Uses the `aes::cipher::KeyInit` trait from `aes` 0.8.2 where appropriate. ### Fixed - Calling `abort_file()` no longer corrupts the archive if called on a shallow copy of a remaining file, or on an archive whose CDR entries are out of sequence. However, it may leave an unused entry in the archive. - Calling `abort_file()` while writing a ZipCrypto-encrypted file no longer causes a crash. - Calling `abort_file()` on the last file before `finish()` no longer produces an invalid ZIP file or garbage in the comment. ### Added - `ZipWriter` methods `get_comment()` and `get_raw_comment()`. ## [0.8.2] ### Fixed - Fixed an issue where code might spuriously fail during write fuzzing. ### Added - New method `with_alignment` on `FileOptions`. ## [0.8.1] ### Fixed - `ZipWriter` now once again implements `Send` if the underlying writer does. ## [0.8.0] ### Deleted - Methods `start_file_aligned`, `start_file_with_extra_data`, `end_local_start_central_extra_data` and `end_extra_data` (see below). ### Changed - Alignment and extra-data fields are now attributes of [`zip::unstable::write::FileOptions`], allowing them to be specified for `add_directory` and `add_symlink`. - Extra-data fields are now formatted by the `FileOptions` method `add_extra_data`. - Improved performance, especially for `shallow_copy_file` and `deep_copy_file` on files with extra data. ### Fixed - Fixes a rare bug where the size of the extra-data field could overflow when `large_file` was set. - Fixes more cases of a bug when ZIP64 magic bytes occur in filenames. ## [0.7.5] ### Fixed - Fixed a bug that occurs when ZIP64 magic bytes occur twice in a filename or across two filenames. ## [0.7.4] ### Added - Added experimental [`zip::unstable::write::FileOptions::with_deprecated_encryption`] API to enable encrypting files with PKWARE encryption. ## [0.7.3] ### Fixed - Fixed a bug that occurs when a filename in a ZIP32 file includes the ZIP64 magic bytes. ## [0.7.2] ### Added - Method `abort_file` - removes the current or most recently-finished file from the archive. ### Fixed - Fixed a bug where a file could remain open for writing after validations failed. ## [0.7.1] ### Changed - Bumped the version number in order to upload an updated README to crates.io. ## [0.7.0] ### Fixed - Calling `start_file` with invalid parameters no longer closes the `ZipWriter`. - Attempting to write a 4GiB file without calling `FileOptions::large_file(true)` now removes the file from the archive but does not close the `ZipWriter`. - Attempting to write a file with an unrepresentable or invalid last-modified date will instead add it with a date of 1980-01-01 00:00:00. ### Added - Method `is_writing_file` - indicates whether a file is open for writing. ## [0.6.13] ### Fixed - Fixed a possible bug in deep_copy_file. ## [0.6.12] ### Fixed - Fixed a Clippy warning that was missed during the last release. ## [0.6.11] ### Fixed - Fixed a bug that could cause later writes to fail after a `deep_copy_file` call. ## [0.6.10] ### Changed - Updated dependency versions. ## [0.6.9] ### Fixed - Fixed an issue that prevented `ZipWriter` from implementing `Send`. ## [0.6.8] ### Added - Detects duplicate filenames. ### Fixed - `deep_copy_file` could set incorrect Unix permissions. - `deep_copy_file` could handle files incorrectly if their compressed size was u32::MAX bytes or less but their uncompressed size was not. - Documented that `deep_copy_file` does not copy a directory's contents. ### Changed - Improved performance of `deep_copy_file` by using a HashMap and eliminating a redundant search. ## [0.6.7] ### Added - `deep_copy_file` method: more standards-compliant way to copy a file from within the ZipWriter ## [0.6.6] ### Fixed - Unused flag `#![feature(read_buf)]` was breaking compatibility with stable compiler. ### Changed - Updated `aes` dependency to `0.8.2` (https://github.com/zip-rs/zip/pull/354) - Updated other dependency versions. ## [0.6.5] ### Changed - Added experimental [`zip::unstable::write::FileOptions::with_deprecated_encryption`] API to enable encrypting files with PKWARE encryption. ### Added - `shallow_copy_file` method: copy a file from within the ZipWriter ## [0.6.4] ### Changed - [#333](https://github.com/zip-rs/zip/pull/333): disabled the default features of the `time` dependency, and also `formatting` and `macros`, as they were enabled by mistake. - Deprecated [`DateTime::from_time`](https://docs.rs/zip/0.6/zip/struct.DateTime.html#method.from_time) in favor of [`DateTime::try_from`](https://docs.rs/zip/0.6/zip/struct.DateTime.html#impl-TryFrom-for-DateTime)
