From: Joe Tsai Date: Thu, 31 Aug 2017 01:49:18 +0000 (-0700) Subject: compress/flate: remove non-standard extensions to flate X-Git-Tag: go1.10beta1~1251 X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=d39649087b9a55ddb1105274963f50842448c3d9;p=gostls13.git compress/flate: remove non-standard extensions to flate Some constants were added to flate that seem to be an experimental attempt at increasing the window size. However, according to RFC1951, the largest window size is 32KiB, so these constants are non-standard. Delete them.
