bpo-43613: Faster implementation of gzip.compress and gzip.decompress
(GH-27941)
Co-authored-by: Łukasz Langa <luk...@langa.pl>
The fix is quite trivial:
--- a/Lib/gzip.py
+++ b/Lib/gzip.py
@@ -587,7 +587,8 @@ def compress(data, compresslevel=_COMPRESS_LEVEL_BEST, *,
mtime=None):
header = _create_simple_gzip_header(compresslevel, mtime)
trailer = struct.pack("<LL", zlib.crc32(data), (len(data) & 0xffffffff))
# Wbits=-15 creates a raw deflate block.
- return header + zlib.compress(data, wbits=-15) + trailer
+ return (header + zlib.compress(data, level=compresslevel, wbits=-15) +
+ trailer)
I'll send a PR.
