* bpo-21872: fix lzma library decompresses data incompletely (GH-14048)animalize2019-09-121-6/+22
| | | | | | | * 1. add test case with wrong behavior * 2. fix bug when max_length == -1 * 3. allow b"" as valid input data for decompress_buf() * 4. when max_length >= 0, let needs_input mechanism works * add more asserts to test case

"self" parameters are also explicitly marked, allowing inspect.Signature() to authoritatively detect (and skip) said parameters. Issue #20326: Argument Clinic now generates separate checksums for the input and output sections of the block, allowing external tools to verify that the input has not changed (and thus the output is not out-of-date).

|\ | | | | | | | | | | | | The underlying C libraries provide no mechanism for serializing compressor and decompressor objects, so actually pickling these classes is impractical. Previously, these objects would be pickled without error, but attempting to use a deserialized instance would segfault the interpreter.

* Make lzma.{encode,decode}_filter_properties private.Nadeem Vawda2012-06-211-20/+14
| | | | | | | | These functions were originally added to support LZMA compression in the zipfile module, and are not of interest for the majority of users. They can be made public in 3.4 if there is user interest, but in the meanwhile, I've opted to present a smaller, simpler API for the module's initial release.
