Subject: Change the limit on the input size for b2a_base64 to what will fit in
X-Git-Tag: v2.2.1c1~966
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=355bc0c88e3c76f1ab688467f150c519f7b0f80a;p=python

Change the limit on the input size for b2a_base64 to what will fit in
memory, rather than the standard's 57.

This fixes SF bug #473009.
