Subject: [PATCH 38/38] viewvcs: switch to `print $zfh'
Date: Sat, 10 Sep 2022 08:17:29 +0000 [thread overview]
Message-ID: <20220910081729.2011934-39-e@80x24.org> (raw)
In-Reply-To: <20220910081729.2011934-1-e@80x24.org>
Again, ->zmore has proven expensive due to the overhead of
calling ->deflate on small strings, so print directly to the
file handle and let the PerlIO::scalar layer take care of
buffering. One of the ->zmore calls was a no-op, even, so
drop that entirely.
