一个WEB服务器的性能测试工具

2000-10-31  David Mosberger  <[e-mail]>

	* Version 0.8 released.

	* core.c (do_recv) [!HAVE_SSL]: Avoid referncing param.use_ssl.
	(do_send): Ditto.

	* core.c (core_ssl_connect): Print error message if SSL connect
	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  <[e-mail]>

	* httperf.man: Update man-page with new options (based on Martin's
	descriptions.

	* httperf.c (usage): Mention --port.

2000-10-27  David Mosberger  <[e-mail]>

	* httperf.man: Mention request summary in description of
	--print-request.

	* stat/print_reply.c (print_request): Print request header/content
	summary line.

	* httperf.c (usage): Bring in sync with implemented options
	(Martin's patch).
	(longopts): Order in alphabetical order (Martin's patch).

2000-10-25  David Mosberger  <[e-mail]>

	* stat/print_reply.c (flush_print_buf): New.
	(Call_Private_Data): New.
	(CALL_PRIVATE_DATA): New.
	(call_private_data_offset): New.
	(print_buf): Rewrite to support line-buffering and new output
	format.
	(call_destroyed): New.
	(print_reply_hdr): New (based on Martin's original version).
	(send_raw_data): Ditto.
	(recv_raw_data): Ditto.
	(recv_stop): Print reply summary (based on Martin's version).
	(init): Update to support the new print options.

	* httperf.c: Replace --print-replies/--print-request with more
	general versions of these options.

	* httperf.man: Add info on new --print-reply and --print-request
	options.

2000-10-24  David Mosberger  <[e-mail]>

	* httperf.c (main): Initialize ssl_ctx.
	(main): Use SSLv3_client_method() instead of SSLv23_client_method().
	The latter doesn't work.

	* 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).

	* core.c (core_ssl_connect): Don't create SSL connection info
	here (done in conn.c now).  Always tell SSL about the
	file descriptor of the socket.

	* sess.c (sess_deinit) [HAVE_SSL]: Free SSL info if it exists.

	* gen/session.c (create_conn): If param.ssl_reuse is in effect,
	re-use SSL session if we have one or update session info with
	newly created SSL session.

	* httperf.c [HAVE_SSL]: Include <openssl/rand.h>.
	(main): Call RAND_seed() with a zero buffer.

2000-10-23  David Mosberger  <[e-mail]>

	* conn.c (conn_init): Don't initialize conn->ssl to zero---that
	has been done by object_new() already.

	* gen/session.c (create_conn): If reusing SSL session ids, create
	SSL structure and save SSL info in session structure.

	* sess.c (sess_deinit) [HAVE_SSL]: Free SSL session if it's
	non-NULL.

	* httperf.h: Declare "use_ssl" only if HAVE_SSL is defined.
	Add ssl_no_reuse and ssl_cipher_list.

	* httperf.c (struct longopts): Add --ssl-no-reuse and ssl-ciphers.
	(main): Handle --ssl-cipher_list and --ssl-no-reuse options.

2000-10-19  David Mosberger  <[e-mail]>

	* core.c (core_ssl_connect): Bring debug messages in sync with
	rest of httperf.  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  <[e-mail]>

	* 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 basic): Change type of hdr_bytes_received,
	reply_bytes_received, and footer_bytes_received from
	size_t to u_wide.
	(dump): Change type of total_size to u_wide.

2000-10-11  David Mosberger  <[e-mail]>

	FD_SETSIZE.

2000-04-25  David Mosberger  <[e-mail]>

	* httperf.c (main): Add a call to fpsetmask(0) to get non-finite
	IEEE arithmetic to work on older versions of FreeBSD.

1998-12-21  David Mosberger  <[e-mail]>

	* Version 0.7 released.

	* Makefile (install): New make target.

	* httperf.h (VERSION): Define as "0.7".

	* gen/wsesslog.c (parse_config): Remove blank in sscanf() format
	since this caused problems on FreeBSD and NetBSD.  This bug was
	reported by Stephane Eranian.

1998-12-08  David Mosberger  <[e-mail]>

	* httperf.c (struct longopts): Add option "method".
	(usage): Document option --method.
	(main): Handle --method.

	* httperf.h (struct Cmdline_Params): New member "method".

	* gen/misc.c: Renamed from add_header.c.  This file now implements
	both --add-header and --method.

1998-11-23  David Mosberger  <[e-mail]>

	* httperf.c (longopts): New option "add-header".
	(main): Handle --add-header.

	* httperf.h (struct Cmdline_Params): New member
	"additional_header".

	* gen/add_header.c: New file.

1998-09-18  David Mosberger  <[e-mail]>

	* gen/session.c (call_done):
	(conn_failed): Call create_conn() instead of sess_failure() in
	case param.retry_on_failure is set and the connection has not been
	successful (received at least one good response)

	* gen/wsess.c (call_destroyed): Call sess_dec_ref() only if
	session didn't fail.

1998-09-14  David Mosberger  <[e-mail]>

	* README: Replace "session" with "connection" and "call" with
	"request" to reflect current terminology (reported by Christian
	Petit).  Also fixed various other typos and grammatical problems.

1998-09-11  David Mosberger  <[e-mail]>

	* 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  <[e-mail]>

	* stat/sess_stat.c: Use sess->failed instead of maintaining
	private session-failure flag.

1998-07-21  David Mosberger  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* Version 0.6 released.

	* gen/wsesslog.c (issue_calls): Limit `to_create' by the number
	of calls that the session can queue.

	(call_recv_hdr): Remove padding bogosity.
	(call_issue): Copy cookie from session to call object.

1998-06-17  David Mosberger  <[e-mail]>

	* timer.c (timer_cancel): Instead of an assertion failure, print a
	message on stderr when timer_cancel(t) is called from within a
	timeout handler t.

	* Feedback from Dick Carter:
	* gen/wsesslog.c (parse_config): Remove stale comment.
	* httperf.h: Fix typo in comment for min_iat.
	* httperf.c (usage): Fix typo in --period args.

	* http.c (get_line): Use sizeof (s->line_buf) instead of
	s->line_buf_size.
