Subject svn commit: r161437 - httpd/httpd/trunk/support/ab.c
Date Fri, 15 Apr 2005 10:51:45 GMT
Author: jorton
Date: Fri Apr 15 03:51:44 2005
New Revision: 161437

URL: http://svn.apache.org/viewcvs?view=rev&rev=161437
Log:
Fix and prevent some segfaults in ab:

* support/ab.c (main): Fail if given concurrency level greater than
number of requests, to prevent segfaults later.
(ssl_print_cert_info): Use the correct buffer size.
(ssl_start_connect): SSL_get_peer_cert_chain doesn't bump refcounts,
so don't free the cert chain here.
(test): Use both calloc parameters (unrelated cleanup).
