Only compare the main version number, e.g. 1.1.1 (first 3 elements
of the version tuple).
Without this change, it would not accept 1.1.1rc1 because that is
not "<= (1, 1, 1)" in that simplistic version comparison.
Separated `chunker_test` into two dedicated test modules: `fixed_test` (for `ChunkerFixed`) and `buzhash_test` (for `Chunker`). Updated imports and adjusted references accordingly.
Moved the `ChunkerFixed` implementation from `chunker` to a new `fixed` module for better modularity. Updated imports and type hints.
Removed now empty chunkers.chunker module.
Moved the `ChunkerFailing` implementation from `chunker` to a new `failing` module for better modularity. Updated imports and type hints. Adjusted related definitions in `chunker.pyi` accordingly.
Moved `buzhash` implementation from `chunker` to a new `buzhash` module for better separation of concerns. Updated imports, adjusted `setup.py` and build configuration accordingly. Removed deprecated `Chunker` definitions from `chunker.pyi`.
Relocated `get_chunker` function from `chunker` module to `chunkers.__init__.py` for improved organization. Updated `Chunker` class signature to include a `sparse` parameter with a default value. Adjusted imports and type hints accordingly.
Extracted the `reader` logic from `chunker` into a dedicated `reader` module to improve modularity and maintainability. Updated imports, references, and build configurations accordingly.
ChunkerFixed can be configured to support files with a specific header size.
But we do not want to get an AssertionError if we encounter a 0-byte file
or a file that is shorter than the header size.
no options yet, just hardcoded macOS and Linux xattrs.
removed the --exclude-nodump option, it is also done automagically now.
also: create: call stat_ext_attrs early
this reads bsdflags, xattrs and ACLs from the
filesystem, except if the user chose to disable that.
notable:
- borg always reads these, even for unchanged files
- if we read them early, borg can now behave differently
based e.g. on a xattr value (and e.g. exclude the file)
we want to get rid of legacy stuff(*) one day and sha256 is as
good for this purpose (and might be even hw accelerated).
(*) considered legacy due to the way it gives the key to the
blake2b function (just padding and prepending it to the data,
instead of using the key parameter, see #8867 ).
Replaced inline file reading logic with `FileReader` to standardize handling across chunkers. Improved buffer updates and allocation handling for sparse files and optimized read operations.
Includes cases for simple reads, multiple reads, and mock chunk scenarios to verify behavior with mixed allocation types.
Also: change Chunk type for empty read result for better consistency.
Simplified and improved handling of mixed types of chunks during reading. The allocation type of resulting chunks is now determined based on contributing chunks.
The `header_size` parameter and related logic have been removed from file readers, simplifying their implementation. This change eliminates unnecessary complexity while maintaining all functional capabilities via `read_size` and `fmap`.
