Subject svn commit: r1455223 - in /httpd/httpd/branches/2.4.x: ./ STATUS modules/ssl/ssl_util_ssl.c
Date Mon, 11 Mar 2013 16:34:19 GMT
Author: jim
Date: Mon Mar 11 16:34:19 2013
New Revision: 1455223

URL: http://svn.apache.org/r1455223
Log:
Merge r1429559, r1451484 from trunk:

According top my testing 'SSL_SESSION_id2sz' is 4x faster with the use 'ap_bin2hex' instead
of
apr_snprintf(..., "%02X" for each character.
Output is the same.

I have left the uppercase conversion, because I'm unsure if it is usefull or not.

SSL_SESSION_id2sz is only used for logging, having it in lowercase shouldn't be an issue.

this is a real issue.
