Ma Lin	f9bedb630e	bpo-41486: Faster bz2/lzma/zlib via new output buffering (GH-21740 ) Faster bz2/lzma/zlib via new output buffering. Also adds .readall() function to _compression.DecompressReader class to take best advantage of this in the consume-all-output at once scenario. Often a 5-20% speedup in common scenarios due to less data copying. Contributed by Ma Lin.	2021-04-27 23:58:54 -07:00

Issue #23529: Limit the size of decompressed data when reading from

GzipFile, BZ2File or LZMAFile.  This defeats denial of service attacks
using compressed bombs (i.e. compressed payloads which decompress to a huge
size).
