Subject: The read() in apr_recv() would always be called first and return EAGAIN.
X-Git-Tag: 2.0.23~140
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=22dbf976702af5487d14153f30becd2055140f76;p=thirdparty%2Fapache%2Fhttpd.git

The read() in apr_recv() would always be called first and return EAGAIN.
This one change to eliminate the read unless there are really bytes to read
is good for a 7 to 9% performance boost on AIX.
