# but Boto 3 seems to have issues with that. No need for fp.name in Boto3
# so just returning the BytesIO directly

# 需要导入模块: from storages.compat import BytesIO [as 别名]
# 或者: from storages.compat.BytesIO import seek [as 别名]

# The GZIP header has a modification time attribute (see http://www.zlib.org/rfc-gzip.html)
# This means each time a file is compressed it changes even if the other contents don't change
# For S3 this defeats detection of changes using MD5 sums on gzipped files
# Fixing the mtime at 0.0 at compression time avoids this problem
