If s->ssl exists already, skip right to SSL_connect(). If SSL_connect() returns SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE, mark the appropriate fd set as active and return immediately to wait for more data. Use ERR_print_errors_fp() to print SSL-related errors. (core_loop): Check for S_CONNECTING state before doing anything else. * README: Document configuration option "--enable-debug". * configure.in: Add support for --enable-debug. 2000-10-16 David Mosberger * configure.in: Add AC_TYPE_LONG_LONG check (defines u_wide as "unsigned long long" if the compiler can grok it, "unsigned long" otherwise). * aclocal.m4: New file. * stat/basic.c: Include "config.h".

(struct longopts): Ditto. * httperf.man: Document --retry-on-failure option. 1998-07-23 David Mosberger * stat/sess_stat.c: Use sess->failed instead of maintaining private session-failure flag. 1998-07-21 David Mosberger * 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 * 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()). (do_recv): No need to check for nread == 0. * stat/basic.c (init): Print basic.conn_lifetime_min only if basic.num_lifetimes > 0. * core.c (core_close): Fix typo (call -> all). 1998-07-08 David Mosberger * core.c (do_send): Set s->state to S_REPLY_STATUS only if this is the first send---we don't want to interfere with the parsing of an in-progress reply. 1998-06-19 David Mosberger * Version 0.6 released. * gen/wsesslog.c (issue_calls): Limit `to_create' by the number of calls that the session can queue. * gen/session.c (session_max_qlen): New function.

(main): Remove uri_wsesslog generator. Add sess_stat stats collector. Handle --max-connections, --max-piped, --print-replies and --session-cookies. Start performance sampling timer. * http.c (get_line): Use sizeof (s->line_buf) instead of s->line_buf_size. (parse_status_line): Do strcmp() to find out whether call was a HEAD request. Ignore `100 Continue' replies. * gen/wsesslog.h: Remove. * gen/wsess.c: Modify to take advantage of session manager (gen/session.c). * gen/wsesslog.c: Modify to take advantage of session manager and merge with uri_wsesslog.c. * gen/uri_wlog.c (set_uri): Use call_set_uri(). * gen/uri_wset.c (set_uri): Ditto. * gen/uri_fixed.c (uri_len): New variable.

This avoids a core-dump under FreeBSD, which seems to have a problem printing IEEE infinity. 1998-05-22 David Mosberger * call.c (method_name): New variable. 1998-04-27 David Mosberger * core.c (do_recv): Ignore EAGAIN errors---Linux 2.0.32 sometimes returns EAGAIN on a read() if a previous write() resulted in EAGAIN. * AUTHORS: New file. 1998-03-24 David Mosberger * gen/wsess.c (call_done): Also fall back to non-persistent session if c->req.version < HTTP/1.1. 1998-03-18 David Mosberger * httperf.c (usage): Fix typo: --recv-buffer -> --send-buffer. * gen/wsess.c (dump): Rename "Sess" to "Session" in statistics output. * core.c (core_connect): Turn on closing with RESET only when param.close_with_reset is set. 1998-03-17 David Mosberger * stat/basic.c (dump): In "Total" line, rename "call" to "req". * Version 0.41 released. * core.c: Include after to get it to compile under FreeBSD (which seems to have a broken libc). * stat/basic.c (dump): Complete renaming of "session" to "call". Rename "Call" to "Request". 1998-03-16 David Mosberger * Version 0.4 released. * httperf.h (VERSION): Change version number to 0.4. * httperf.c: (longopts): Add --http-version. (main): Initialize param.http_version to HTTP/1. Support parsing of --http-version option. Echo --http-version option if version other than 1.1 is selected. * httperf.h (struct Cmdline_Params): New member HTTP_VERSION. * core.c (core_send): Support generation of HTTP/1.0 requests. * Patches by Stephane Eranian: * httperf.man: Mention --wlog parameter. * Makefile (clean): Use $(MAKE) instead of make. 1998-03-12 David Mosberger * httperf.c: Renamed Session to Conn to avoid confusion between user sessions and TCP connections. 1998-03-02 David Mosberger * gen/wsess.c (user_destroy): Signal EV_USER_DESTROYED.

(req_create): Modify to support bursts. (user_connect): Ditto. (sess_destroyed): Ditto. (call_destroyed): Ditto. 1998-02-25 David Mosberger * core.c (lffs): Fix lffs() so it returns 0 when no bits at all are set in a 64 bit long. (set_active): Set recvq timeout if timeout==0.0 (the old code failed to timeout connections that were waiting for replies). 1998-02-23 David Mosberger * Version 0.3 released. * timer.c (timer_now_forced): New function. * httperf.h (Cmdline_params): New member burst_len. * httperf.c: New option --burst-length. At present, only gen/call_seq.c supports this (gen/wsess does not). * gen/wsess.c (struct User): New members: found_close_hdr, conn_start, call_start, and cookie. (req_create): Insert cookie as extra header if there is one. (call_recv_hdr): New function. Looks for "Connection: close" and "Set-Cookie:" headers. * gen/call_seq.c (Sess_Private_Data): New member "num_finished". (issue_calls): Add support for --burst-len parameter. (call_destroyed): Ditto. * core.c (SYSCALL): Call timer_now_forced() instead of timer_now(). (core_connect): Keep track of longest back-to-back burst. (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 * stat/basic.c (sess_fail): Print one unexpected error number per execution, independent of DBG. 1998-02-06 David Mosberger * core.c (do_send): Maintain sendq_tail & recvq_tail.

(do_send): Set c->timeout. (core_connect): Ditto. (core_send): Ditto. * call.h: Replace (unused) WATCHDOG member with TIMEOUT. * timer.c (timer_schedule): Handle negative delays gracefully. 1998-01-28 David Mosberger * Version 0.2 released to SixFlags team. 1998-01-26 David Mosberger * gen/call_seq.c (sess_closed): New function. (init): Register sess_closed() so we notice when session closes prematurely. 1998-01-21 David Mosberger * 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 * stat/basic.c (dump): Add num_sock_reset to total error count. 1998-01-12 David Mosberger * stat/basic.c (struct basic): New member num_sock_reset.

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 * 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 * stat/basic.c (dump): Print minmum rate as zero if there are no rate samples. 1997-12-23 David Mosberger * 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 * 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).
