If s->ssl exists already, skip right to SSL_connect().

Also fixed various other typos and grammatical problems. 1998-09-11 David Mosberger <davidm@hpl.hp.com> * gen/session.c (call_done): When param.retry_on_failure is set, re-issue call instead of causing session to fail. * httperf.c (usage): Add --retry-on-failure option. (struct longopts): Ditto. * httperf.man: Document --retry-on-failure option. 1998-07-23 David Mosberger <davidm@hpl.hp.com> * stat/sess_stat.c: Use sess->failed instead of maintaining private session-failure flag. 1998-07-21 David Mosberger <davidm@hpl.hp.com> * sess.c (sess_failure): Don't signal EV_SESS_FAILED more than once per session. * core.c (do_send): Clear c->recvq_next. This is necessary now because the same call may be issued multiple times (due to connection failures). Hence there is no longer a guarantee that c->recvq_next has been cleared by object_new(). (do_send): Rename s to conn and c to call. 1998-07-20 David Mosberger-Tang <David.Mosberger@acm.org> * core.c (do_recv): Set s->state to S_REPLY_DONE when done with an HTTP/1.0 response (mirrors code in http_process_reply_bytes()).

(core_connect): Set SO_LINGER option so that TCP RST is sent when closing the socket. This avoids the client melting down on HP-UX 10.20 due to a large number of TCP connections in TIME_WAIT state (HP-UX is broken as far as bind()/connect() is concerned when there are many TCP control blocks). (core_exit): Print maximum connect burst length. * core.c (max_burst_len): New variable to keep track of longest back-to-back burst generated (large bursts are usually a sign of the client being overloaded). 1998-02-13 David Mosberger <davidm@hpl.hp.com> * stat/basic.c (sess_fail): Print one unexpected error number per execution, independent of DBG. 1998-02-06 David Mosberger <davidm@hpl.hp.com> * core.c (do_send): Maintain sendq_tail & recvq_tail.

(init): Register sess_closed() so we notice when session closes prematurely. 1998-01-21 David Mosberger <davidm@hpl.hp.com> * httperf.c (main): Don't quit after printing version information---it's useful to run a test and have this info as well. 1998-01-14 David Mosberger <davidm@hpl.hp.com> * stat/basic.c (dump): Add num_sock_reset to total error count. 1998-01-12 David Mosberger <davidm@hpl.hp.com> * stat/basic.c (struct basic): New member num_sock_reset. (sess_fail): Increment num_sock_reset for ECONNRESET. (dump): Print num_sock_reset. * core.c (do_recv): Call session_failure() when reading < 0 bytes. * stat/basic.c (sess_fail): Print error number when getting an unexpected errno and DBG > 0. 1998-01-09 David Mosberger <davidm@hpl.hp.com> * httperf.c (main): Print only one newline (second newline is printed by stat collectors). * stat/basic.c (dump): Print session lifetime histogram first (so it goes right after the rate output). 1998-01-08 David Mosberger <davidm@hpl.hp.com> * core.c (port_get): Recode so port numbers are returned in strictly increasing order (until a wraparound after 65535 occurs). This avoids problems with NT 4.0 which disallows reusing the port pair of a properly shut down TCP connection (which creates problems when testing an NT server with clients running on HP-UX or similar platforms). 1998-01-07 David Mosberger <davidm@hpl.hp.com> * gen/sess_rate.c: Adapt to use rate.c. * timer.c (timer_schedule): Adjust "delay" if realtime has grown bigger than next_tick (meaning that "spoke" is behind). * call.c (call_destroy): prev wasn't updated in the search loop. 1998-01-06 David Mosberger <davidm@hpl.hp.com> * stat/basic.c (dump): Print minmum rate as zero if there are no rate samples. 1997-12-23 David Mosberger <davidm@hpl.hp.com> * stat/basic.c (struct basic): Add members num_reply_rates, reply_rate_sum, reply_rate_sum2, reply_rate_min, and reply_rate_max. (interval_start, num_replies): New vars. (sample_rate): New function to sample reply rate. (init): Schedule rate sampler. (dump): Print min, avg, max, and stddev of sampled reply rate. * httperf.c: Add --client and --think-timeout options. 1997-12-17 David Mosberger <davidm@hpl.hp.com> * http.c (parse_data): Return TRUE to indicate that all bytes (of present chunk) have been received (instead of setting state to S_REPLY_DONE). * httperf.h (ALIGN): Fix macro (need AND with _complement_...). * http.c (xfer_chunked): Fix typo: check for content_bytes >= content_length (not vice versa). * uri_wset.c (set_uri): Fix uri_len computation. * sess_rate.c (destroyed): Fix typo: test for param.rate <= 0 (not <0).
