2006-12-08 Ted Bullock <tbullock@canada.com>
* Bug Fixes: Added a number of fixes from the mailing lists
over the last 6 years.
* compiler warnings: Compiler warnings in core.c and wsesslog.c
* configuration: Fixes a problem with the "configure" setup
where the "--prefix=" option wasn't being obeyed
* zero length: Fixes bug in http.c (parse_header)with zero
length content
* Host Header: Identify machine by FQD rather than hostname
* Persistent Connections: Added Persistent connections to HTTP 1.0
requests
* Robust alloca.h: Robust way to handle the header file that
defines the alloca function <alloca.h> for linux and stdlib.h for
BSD and others
* Time Discrepancy: Fixed a discrepancy between the data produced
by httperf and the documentation in regards to timing.
* wsesslog Crash: Fixed a problem with the wsesslog crashing
httperf due to an unhandled session failure from a burdened server

fails. ERR_print_errors_fp() may not print anything if there
error is due to, e.g., trying to connect to a non-existent port.
* httperf.c (main): Initialize port to -1. Once parameters have
been processed, port defaults to 443 if SSL is in use, 80
otherwise.
2000-10-30 David Mosberger <davidm@hpl.hp.com>

* httperf.h (ssl_ctx): New global variable.
* conn.h [HAVE_SSL]: Drop unnecessary includes of <openssl/rsa.h>,
<openssl/crypto.h>, <openssl/x509.h>, and <openssl/pem.h>. Drop
per-connect "ctx" member (it's global now).
* conn.c (conn_init): Create SSL connection info and set cipher
list (if necessary).

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.

1998-07-08 David Mosberger <davidm@hpl.hp.com>
* 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 <davidm@hpl.hp.com>

(sess_destroyed): Ditto.
(call_destroyed): Ditto.
1998-02-25 David Mosberger <davidm@hpl.hp.com>
* 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 <davidm@hpl.hp.com>
* Version 0.3 released.
* timer.c (timer_now_forced): New function.

(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).

(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).

-*-Mode: outline-*-
* New in version 0.8.1:
** Numerous bug fixes. See ChangeLog for details
* New in version 0.8:
** httperf is now released under the GNU General Public License (GPL).
** Preliminary support for SSL (Secure Socket Layer). See README for details.
** New options (see man-page for details):
--print-reply (replaced --print-replies)
--print-request
--ssl
--ssl-ciphers
--ssl-no-reuse
* New in version 0.7:
** New options (see man-page for details):
--add-header
--method
--retry-on-failure
** Bug fixes
- fixed some segfaults in the session workload generator
- specifying option --session-cookie when not using a session
workload generator now prints an error message instead of
core dumping
* New in version 0.6:
** New options (see man-page for details):
--max-connections
--max-piped-calls
--print-replies
--session-cookies
** Cookie support now must be requested explicitly when using a session-based
workload generator. To do this, specify option --session-cookie.
* New in version 0.5:
** Normal connection closing is the default again. To request closing TCP
connections with a RESET, specify option --close-with-reset.
** --wsesslog option added to support log-file based session
specification (contributed by Dick Carter).
** --period option added to allow a more flexible way to specify
session/connection interarrival time. Unlike the --rate
argument, this allows deterministic (fixed), uniform, and
exponentially distributed interarrival times (contributed by Dick
Carter).
** Various bug fixes (see ChangeLog for details).
* New in version 0.41:
** In basic statistic, rename "call" to "request".
* New in version 0.4:
** Option --http-version can be used to select the HTTP protocol version
used in sending requests. 1.0 and 1.0 are the only allowed values
for this option at this point.
** What used to be called a "session" is now called a "connection". This
reduces confusion between TCP connections and user sessions.
** Stephane's log-file based URL generated has been added.
** The session workload generator now supports the --burst-length
parameter to generate bursty session.
