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

cfbb218b42 [MINOR] added some comments to the places where we can send a pending connection to a server in case of throttling. 2006-04-15 22:46:38 +02:00

a647c7051e [MINOR] maintain the number of sessions per server and add this info to the logs 2006-04-15 22:45:52 +02:00

c0d4bbdc8d [VERSION] updated everything to reflect version 1.2.12. 2006-04-15 21:47:50 +02:00

2c51373bfa [MINOR] optionnal '-s' command line argument could clobber '-st' and '-sf' 2006-04-15 19:25:16 +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.

06a1205f57 * it might have been possible that a flapping server would not have been 
detected UP is responding just before being declared down.

d2058dc491 * updated CHANGELOG and haproxy.c to display version 1.2.11 2006-03-25 20:35:41 +01:00

bf8ff3d4cc * added the '-db' command-line option to disable backgrounding. 2006-03-25 20:33:48 +01:00
willy tarreau
53e99701c6 * added the -sf/-st command-line arguments which are used to specify 
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.
 2006-03-25 20:33:42 +01:00
willy tarreau
41310e7d9d * reworked the startup mechanism to allow the sending of a signal to a list 
of old pids if a socket cannot be bound, with a retry for a limited amount
  of time (1 second by default).
 2006-03-25 20:33:33 +01:00

746e26b180 * added the ability to enforce limits on memory usage. 2006-03-25 20:33:22 +01:00
willy tarreau
1a3442daee * added the 'source' load-balancing algorithm which uses the source IP(v4|v6) 2006-03-25 20:33:17 +01:00
willy tarreau
4c8c2b5f08 * re-architectured the server round-robin mechanism to ease integration of 
other algorithms. It now relies on the number of active and backup servers.
 2006-03-25 20:33:10 +01:00
willy tarreau
62084d4f2d * added a counter for the number of active and backup servers, and report 
these numbers upon SIGHUP or state change.

72e583d030 While fixing the backup server round-robin "feature", a new bug was introduced 
which could miss some backup servers.

1fb3493492 * The displayed proxy name was wrong when dumping upon SIGHUP. 2006-03-23 11:22:10 +01:00

fd6dfe7c76 Fixed some messages to ease parsing of alerts. 2006-03-19 19:38:19 +01:00

25424f8558 Make health-checks be more regular, and faster to retry after a timeout. 2006-03-19 19:37:48 +01:00

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.
 2006-03-19 19:36:48 +01:00

05be12bb20 Make fd management more robust and easier to debug. Also some micro-optimisations. 2006-03-19 19:35:00 +01:00

dd676173f0 * automatically deduce ulimit-n from maxsock 2006-03-12 18:01:33 +01:00
Willy TARREAU
203b0b624f * account for the sockets needed for listeners and checks 
during computation of maximum number of sockets.
 2006-03-12 18:00:28 +01:00
Willy TARREAU
13032e769e * added the ability to enforce a maximum number of connections at compile time via SYSTEM_MAXCONN. 2006-03-12 17:49:02 +01:00
willy tarreau
b5669e94ae * implemented support for multi-line headers as required by RFC2616. 2006-03-02 16:50:45 +01:00
Willy TARREAU
3759f98d44 * health checks sent to servers configured with identical intervals 
were sent in perfect synchronisation because the initial time was
  the same for all. This could induce high load peaks when fragile
  servers were hosting tens of instances for the same application.
  Now the load is spread evenly across the smallest interval amongst
  a listener.

767ba71444 * the default 'httpclose' option only sets the 'Connection:' headers 
to 'close', but does not actually close any connection. The problem
  is, there are some servers which don't close the connection even if
  the proxy tells them 'Connection: close'. A workaround was added by
  the way of a new option 'forceclose' (which implies 'httpclose'),
  and which makes the proxy close the outgoing channel to the server
  once it has sent all its headers. Just don't use this with the
  'CONNECT' method of course !

3481c46368 * there was a bug in the way the backup servers were handled. They 
were erroneously load-balanced while the doc said the opposite.
  Since load-balanced backup servers is one of the features some
  people have been asking for, the problem was fixed to reflect the
  documented behaviour and a new option 'allbackups' was introduced
  to provide the feature to those who need it.

b45124729a * some commented out debug code was not usable. This is fixed. 2006-03-01 22:34:48 +01:00
Willy TARREAU
1cec83c754 * a never ending connect() could lead to a fast select() loop if 
its timeout times the number of retransmits exceeded the server
  read or write timeout, because the later was used to compute
  select()'s timeout while the connection timeout was not reached.
 2006-03-01 22:33:49 +01:00
Willy TARREAU
c9a643998f * fixed some tv_cmp_ms() computations. Strictly speaking, there was 
a very short window of 1 microsecond every millisecond during which
  two events were not considered as 1 ms apart from each other.
 2006-03-01 22:30:20 +01:00
Willy TARREAU
a9e75f6eff * now we initialize the libc's localtime structures very early so 
that even under OOM conditions, we can still send dated error
  messages without segfaulting.
 2006-03-01 22:27:48 +01:00
Willy TARREAU
e3283d1cd3 * daemon mode must imply 'quiet' and disable 'verbose' as 
stdout/stderr file descriptors are closed.
