36 ** - Originally written by Adam Twiss <adam@zeus.co.uk>, March 1996
37 ** with input from Mike Belshe <mbelshe@netscape.com> and
38 ** Michael Campanella <campanella@stevms.enet.dec.com>
39 ** - Enhanced by Dean Gaudet <dgaudet@apache.org>, November 1997
40 ** - Cleaned up by Ralf S. Engelschall <rse@apache.org>, March 1998
41 ** - POST and verbosity by Kurt Sussman <kls@merlot.com>, August 1998
42 ** - HTML table output added by David N. Welton <davidw@prosa.it>, January 1999
43 ** - Added Cookie, Arbitrary header and auth support. <dirkx@webweaving.org>, April 1999
45 ** - Increased version number - as some of the socket/error handling has
46 ** fundamentally changed - and will give fundamentally different results
47 ** in situations where a server is dropping requests. Therefore you can
48 ** no longer compare results of AB as easily. Hence the inc of the version.
49 ** They should be closer to the truth though. Sander & <dirkx@covalent.net>, End 2000.
50 ** - Fixed proxy functionality, added median/mean statistics, added gnuplot
51 ** output option, added _experimental/rudimentary_ SSL support. Added
52 ** confidence guestimators and warnings. Sander & <dirkx@covalent.net>, End 2000
53 ** - Fixed serious int overflow issues which would cause realistic (longer
54 ** than a few minutes) run's to have wrong (but believable) results. Added
55 ** trapping of connection errors which influenced measurements.
56 ** Contributed by Sander Temme, Early 2001
58 ** - Changed timeout behavour during write to work whilst the sockets
59 ** are filling up and apr_write() does writes a few - but not all.
60 ** This will potentially change results. <dirkx@webweaving.org>, April 2001
62 ** Improvements to concurrent processing:
63 ** - Enabled non-blocking connect()s.
64 ** - Prevent blocking calls to apr_socket_recv() (thereby allowing AB to
65 ** manage its entire set of socket descriptors).
66 ** - Any error returned from apr_socket_recv() that is not EAGAIN or EOF
67 ** is now treated as fatal.
68 ** Contributed by Aaron Bannert, April 24, 2002
71 ** Internalized the version string - this string is part
72 ** of the Agent: header and the result output.
75 ** Adopted SSL code by Madhu Mathihalli <madhusudan_mathihalli@hp.com>
76 ** [PATCH] ab with SSL support Posted Wed, 15 Aug 2001 20:55:06 GMT
77 ** Introduces four 'if (int == value)' tests per non-ssl request.
80 ** Switched to the new abstract pollset API, allowing ab to
81 ** take advantage of future apr_pollset_t scalability improvements.
82 ** Contributed by Brian Pane, August 31, 2002
85 ** SIGINT now triggers output_results().

89 /* Note: this version string should start with \d+[\d\.]* and be a valid
90 * string for an HTTP Agent: header when prefixed with 'ApacheBench/'.
91 * It should reflect the version of AB - and not that of the apache server
92 * it happens to accompany. And it should be updated or changed whenever
93 * the results are no longer fundamentally comparable to the results of
94 * a previous version of ab. Either due to a change in the logic of
95 * ab - or to due to a change in the distribution it is compiled with
