422bb2e79f [MEDIUM] in the request, always consider empty cookies as invalid. 
This solves a problem of unwanted stickyness to backup servers when some
clients incidentely memorize an empty cookie.

4f7a101265 [MINOR] set the expiration date when removing a cookie 
It was specified in the documentation that a cookie would be deleted if the
client was switched to a cookie-less server such as a backup server, in
order to avoid stickyness on errors. To achieve this, an empty cookie was
returned. It seems this no longer works (at least with Firefox 1.5 and
Mozilla 1.8a5), because the browser returns the empty cookie. The cookie
specification says that in order to remove a cookie, it must be accompanied
by an expiration date in the past, so this is what we do. Tested on Mozilla
1.8a5, works.

f2b8d30d93 [MINOR] swapped the queued and active sessions in the logs 
It was not natural to read sess/pend/lsess/psess in the logs, so before
the feature became official, I've swapped them to read :

   pend/sess/lsess/psess

Where <pend> is the overall number of pending connections on this instance,
including all the servers queues, <sess> is the number of sessions remaining
active on the server when the log was emitted (after the end of the session,
or after parsing the request), <lsess> and <psess> are the number of active
sessions on the listener and on the process respectively.

dab722b6b7 [MINOR] uninlining 6 very common functions saved 15% code size and improved perf 
by about 1-2% :
  tv_delayfrom, tv_cmp_ms, tv_cmp2, tv_cmp2_ms, tv_remain2, fd_delete

bc2eda6fda [MEDIUM] when a server goes up, it now steals part of the proxy's queue. 2006-05-04 15:16:23 +02:00

2812edcde8 [MEDIUM] redispatch queued sessions if possible when a server goes down. 2006-05-04 12:09:37 +02:00
willy tarreau
45526ed05b [MEDIUM] apply the contimeout to the queue by default. 
An improvement will be to have a separate timeout for the queue.

4632c21c11 [MINOR] updated the sig_dump_state() output to show the conn queue state. 2006-05-02 23:32:51 +02:00

f32f52404b [MEDIUM] logs now show the time spent in the queue and the number of sessions 
already waiting at accept() time. This number of session is global per instance
so it does not reflect one particular server.

5e698ef509 [MEDIUM] slightly optimize the scheduler for non-expirable tasks. 
The non-expirable tasks are now sent to a dedicated wait-queue so that
they do not pollute the other ones anymore. This is a temporary dirty
hack which will go away with the new O(log(n)) scheduler.

dfece23f7d [MAJOR] first limited implementation of connection queueing. 
There is no timeout yet, and the server UP/DOWN events are not used
	to export/import list of connections yet. It seems that the process
	can sometimes eat lots of user CPU (~50%) if a maxconn is set on an
	overloaded server.

a5e8c663a9 [MINOR] stupid bug which caused two different session flags to use the same bit. 
Fortunately, this had no side effect because they were not used in same areas.

7feab59518 [MINOR] always process the run queue from the head. 
This ensures that any task wan wake any other task up and that it will be
processed too.

898db9d595 [MEDIUM] now the round-robin load balancer uses two passes to avoid saturated servers. The first avoids servers which have filled with maxconn connections, and a second pass can enforce the selection of one of them if the first pass found no candidate. 2006-04-15 22:59:58 +02:00
willy tarreau
18a957c325 [MEDIUM] added the necessary infrastructure to support per-server session limits : - the "maxconn" config option - the new SV_STCPEND state (connection pending) - a per-server pending connections queue 2006-04-15 22:59:34 +02:00
willy tarreau
14b4d43db3 [MEDIUM] added the total number of sessions per server and per proxy and we now report it in the dumps. 2006-04-15 22:47:12 +02:00

cc1e2bda20 * implemented the weighted load balancing based on a server map. 
Weighted roundrobin and weighted source hash are now supported.
 2006-04-15 19:02:24 +02:00
willy tarreau
e3f023f677 * added the 'weight' parameter to the servers, limited to 1..256. 
It is factored between all the servers so that the servers map
  will be smaller and easier to construct.

a list of pids to send a FINISH or TERMINATE signal upon startup.
  They will also be asked to release their port if a bind fails.

41310e7d9d * reworked the startup mechanism to allow the sending of a signal to a list

  of time (1 second by default).

4c8c2b5f08 * re-architectured the server round-robin mechanism to ease integration of

c2becdc403 Limit the number of consecutive accept() in multi-process mode. 
This produces a more evenly distributed load across the processes and slightly
improves performance by reducing bottlenecks.
