* fixed a stupid bug introduced in 1.1.22 which caused second and subsequent
'default' sections to keep previous parameters, and not initialize logs
correctly.
* fixed a second stupid bug introduced in 1.1.22 which caused configurations
relying on 'dispatch' mode to segfault at the first connection.
* 'option httpchk' now supports method, HTTP version and a few headers.
* now, 'option httpchk', 'cookie' and 'capture' can be specified in
'defaults' section
* a fresh new english documentation
* large Makefile cleanup for increased portability
* new build script 'build.cfg' for Formilux-0.1.8
* new startup script 'init.haproxy.flx0' for Formilux-0.1.8
* 'listen' now supports optionnal address:port-range lists
* 'bind' introduced to add new listen addresses
* fixed a bug which caused a session to be kept established on a server till
it timed out if the client closed during the DATA phase.
* the port part of each server address can now be empty to make the proxy
connect to the server on the same port it was connected to, be an absolute
unsigned number to reflect a single port (as in older versions), or an
explicitly signed number (+N/-N) to indicate that this offset must be
applied to the port the proxy was connected to, when connecting to the
server.
* the 'port' server option allows the user to specify a different
health-check port than the service one. It is mandatory when only relative
ports have been specified and check is required. By default, the checks are
sent to the service port.
* new 'defaults' section which is rather similar to 'listen' except that all
values are only used as default values for future 'listen' sections, until
a new 'defaults' resets them. At the moment, server options, regexes,
cookie names and captures cannot be set in the 'defaults' section.
* Makefile now optimizes for Ultrasparc by default on Solaris/Sparc
* large documentation updates and fixes
* new 'tests' directory with some debug files
* 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 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
* 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
* 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
* 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().
