Engelschall , March 1998 ** - POST and verbosity by Kurt Sussman , August 1998 ** - HTML table output added by David N. Welton , January 1999 ** - Added Cookie, Arbitrary header and auth support. , April 1999 ** Version 1.3d ** - Increased version number - as some of the socket/error handling has ** fundamentally changed - and will give fundamentally different results ** in situations where a server is dropping requests. Therefore you can ** no longer compare results of AB as easily. Hence the inc of the version. ** They should be closer to the truth though. Sander & , End 2000. ** - Fixed proxy functionality, added median/mean statistics, added gnuplot ** output option, added _experimental/rudimentary_ SSL support. Added ** confidence guestimators and warnings. Sander & , End 2000 ** - Fixed serious int overflow issues which would cause realistic (longer ** than a few minutes) run's to have wrong (but believable) results. Added ** trapping of connection errors which influenced measurements. ** Contributed by Sander Temme, Early 2001 ** Version 1.3e ** - Changed timeout behavour during write to work whilst the sockets ** are filling up and apr_write() does writes a few - but not all. ** This will potentially change results. , April 2001 ** Version 2.0.36-dev ** Improvements to concurrent processing: ** - Enabled non-blocking connect()s. ** - Prevent blocking calls to apr_recv() (thereby allowing AB to ** manage its entire set of socket descriptors). ** - Any error returned from apr_recv() that is not EAGAIN or EOF ** is now treated as fatal. ** Contributed by Aaron Bannert, April 24, 2002 ** ** Version 2.0.36-2 ** Internalized the version string - this string is part ** of the Agent: header and the result output. ** ** Version 2.0.37-dev ** Adopted SSL code by Madhu Mathihalli ** [PATCH] ab with SSL support Posted Wed, 15 Aug 2001 20:55:06 GMT ** Introduces four 'if (int == value)' tests per non-ssl request. ** ** Version 2.0.40-dev ** Switched to the new abstract pollset API, allowing ab to ** take advantage of future apr_pollset_t scalability improvements. ** Contributed by Brian Pane, August 31, 2002 **/ /* Note: this version string should start with \d+[\d\.]* and be a valid * string for an HTTP Agent: header when prefixed with 'ApacheBench/'. * It should reflect the version of AB - and not that of the apache server * it happens to accompany. And it should be updated or changed whenever * the results are no longer fundamentally comparable to the results of * a previous version of ab. Either due to a change in the logic of * ab - or to due to a change in the distribution it is compiled with * (such as an APR change in for example blocking). */ #define AP_AB_BASEREVISION "2.0.40-dev" /* * BUGS: * * - uses strcpy/etc. * - has various other poor buffer attacks related to the lazy parsing of * response headers from the server * - doesn't implement much of HTTP/1.x, only accepts certain forms of * responses * - (performance problem) heavy use of strstr shows up top in profile * only an issue for loopback usage */ /* -------------------------------------------------------------------- */ #if 'A' != 0x41 /* Hmmm...
