* fixed two problems with time-outs, one where a server would be logged as
timed out during transfer that take longer to complete than the fixed
time-out, and one where clients were logged as timed-out during the data
phase because they didn't have anything to send. This sometimes caused
slow client connections to close too early while in fact there was no
problem. The proper fix would be to have a per-fd time-out with
conditions depending on the state of the HTTP FSM.
* haproxy was NOT RFC compliant because it was case-sensitive on HTTP
"Cookie:" and "Set-Cookie:" headers. This caused JVM 1.4 to fail on
cookie persistence because it uses "cookie:". Two memcmp() have been
replaced with strncasecmp().
* added the haproxy2html.sh script
* removed the now useless NOTES file
* made pcre-config quiet in the makefile.
* Haproxy can be compiled with PCRE regex instead of libc regex, by setting
REGEX=pcre on the make command line.
* HTTP health-checks now use "OPTIONS *" instead of "OPTIONS /".
* when explicit source address binding is required, it is now also used for
health-checks.
* added 'reqpass' and 'reqipass' to allow certain headers but not the request
itself.
* factored several strings to reduce binary size by about 2 kB.
* replaced setreuid() and setregid() with more standard setuid() and setgid().
* added 4 status flags to the log line indicating who ended the connection
first, the sessions state, the validity of the cookie, and action taken on
the set-cookie header.
* rearranged the changelog and removed it from haproxy.c
* large documentation updates
* add the notion of "backup" servers, which are used only when all other
servers are down.
* make Set-Cookie return "" instead of "(null)" when the server has no
cookie assigned (useful for backup servers).
* "log" now supports an optionnal level name (info, notice, err ...) above
which nothing is sent.
* replaced some strncmp() with memcmp() for better efficiency.
* added "capture cookie" option which logs client and/or server cookies
* cleaned up/down messages and dump servers states upon SIGHUP
* added a redirection feature for errors : "errorloc <errnum> <url>"
* now we won't insist on connecting to a dead server, even with a cookie,
unless option "persist" is specified.
* added HTTP/408 response for client request time-out and HTTP/50[234] for
server reply time-out or errors.
* updates to the examples files
* added a 'do_status' command to the Formilux init script
* replaced setpgid()/setpgrp() with setsid() for better portability, because
setpgrp() doesn't have the same meaning under Solaris, Linux, and OpenBSD.
* fixed stats monitoring, and optimized some tv_* for most common cases.
* replaced temporary 'newhdr' with 'trash' to reduce stack size
* made HTTP errors more HTML-fiendly.
* renamed strlcpy() to strlcpy2() because of a slightly difference between
their behaviour (return value), to avoid confusion.
* restricted HTTP messages to HTTP proxies only
* added a 502 message when the connection has been refused by the server,
to prevent clients from believing this is a zero-byte HTTP 0.9 reply.
* changed 'Cache-control:' from 'no-cache="set-cookie"' to 'private' when
inserting a cookie, because some caches (apache) don't understand it.
* fixed processing of server headers when client is in SHUTR state
* automatically close fd's 0,1 and 2 when going daemon ; setpgrp() after
setpgid()
* updated the Makefile and the Formilux build script
* fixed multi-cookie handling in client request to allow clean deletion
in insert+indirect mode. Now, only the server cookie is deleted and not
all the header. Should now be compliant to RFC2109.
* added a "nocache" option to "cookie" to specify that we explicitly want
to add a "cache-control" header when we add a cookie.
It is also possible to add an "Expires: <old-date>" to keep compatibility
with old/broken caches.
* some doc and examples cleanups
* if a cookie is used in insert+indirect mode, it's desirable that the
the servers don't see it. It was not possible to remove it correctly
with regexps, so now it's removed automatically.
* don't use snprintf()'s return value as an end of message since it may
be larger. This caused bus errors and segfaults in internal libc's
getenv() during localtime() in send_log().
* removed dead insecure send_syslog() function and all references to it.
* fixed warnings on Solaris due to buggy implementation of isXXXX().
* option "dontlognull"
* fixed "double space" bug in config parser
* fixed an uninitialized server field in case of dispatch
with no existing server which could cause a segfault during
logging.
* the pid logged was always the father's, which was wrong for daemons.
* fixed wrong level "LOG_INFO" for message "proxy started".
* http logging is now complete :
- ip:port, date, proxy, server
- req_time, conn_time, hdr_time, tot_time
- status, size, request
* source address binding
* regex are now chained and not limited anymore.
* unavailable server now returns HTTP/502.
* increased per-line args limit to 40
* added reqallow/reqdeny to block some request on matches
* added HTTP 400/403 responses
* added a 'NOTES' file
* connection logging displayed incorrect source address.
* added proxy start/stop and server up/down log events.
* replaced log message short buffers with larger trash.
* enlarged buffer to 8 kB and replace buffer to 4 kB.
* added a config.rc example for Formilux
* added a build script for Formilux
* fixed a bug in buffer management where we could have a loop
between event_read() and process_{cli|srv} if R==BUFSIZE-MAXREWRITE.
=> implemented an adjustable buffer limit.
* fixed a bug : expiration of tasks in wait queue timeout is used again,
and running tasks are skipped.
* added some debug lines for accept events.
* send warnings for servers up/down.
* added OpenBSD, Linux-2.2 and Linux-2.4 targets to the Makefile
* added a Formilux init script
* fixed a few timeout bugs
* rearranged the task scheduler subsystem to improve performance,
add new tasks, and make it easier to later port to librt ;
* allow multiple accept() for one select() wake up ;
* implemented internal load balancing with basic health-check ;
* cookie insertion and header add/replace/delete, with better strings
support.
* reworked buffer handling to fix a few rewrite bugs, and
improve overall performance.
* implement the "purge" option to delete server cookies in direct mode.
* fixed some error cases where the maxfd was not decreased.
* now supports transparent proxying, at least on linux 2.4.
* soft stop works again (fixed select timeout computation).
* it seems that TCP proxies sometimes cannot timeout.
* added a "quiet" mode.
* enforce file descriptor limitation on socket() and accept().
