[New-bugs-announce] [issue41725] bz2 would use a dedicated exception for data error

[Michał Górny]

New submission from Michał Górny <mgorny at gentoo.org>:

Currently, the bz2 extension functions raise a generic OSError() on BZ_DATA_ERROR and BZ_DATA_ERROR_MAGIC.  When working on files, this makes it unnecessarily hard to catch compressor errors (i.e. invalid bz2 input file) without catching system I/O errors.  Could you please consider adding a new exception type for bz2 errors, akin to gzip.BadGzipFile?
