* changed the debug output format so that it now includes the session unique
ID followed by the instance name at the beginning of each line.
* in debug mode, accept now shows the client's IP and port.
* added one 3 small debugging scripts to search and pretty print debug output
* changed the default health check request to "OPTIONS /" instead of
"OPTIONS *" since not all servers implement the later one.
* "option httpchk" now accepts an optional parameter allowing the user to
specify and URI other than '/' during health-checks.
* made Makefile more robust to pcre-config errors
* added 3 new pretty-print scripts : debug2ansi, debug2html and debugfind
* upgraded Formilux package to haproxy-1.1.21-flx.1.pkg
* removed the now obsolete haproxy2html.sh
* 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
* 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
* 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
* 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().
