This Linux-specific option was never really used in production and
has since been superseded by new splicing options brought by recent
Linux kernels.
It caused several particular cases in the code because the kernel
would take care of the session without haproxy being able to do
anything on it, which became hard to handle in the new architecture.
Let's simply get rid of it now that there is a replacement available.

When trying to build a 32-bit binary on a 64-bit platform, we generally
need to pass "-m32" to gcc, which is not convenient with current makefile.
Note that this option requires gcc >= 3.
In order to ease parameter passing, a new ARCH= makefile option has been
added. If it receives a target architecture, according "-m32"/"-m64" and
"-march=xxxx" will be passed to gcc. Only the generic makefile has been
changed to support this option right now as the need only appeared on Linux.
The spec file now makes use of this option so that rpmbuild can automatically
build with the proper architecture.

that's using perl.

Hello,
You will find attached an updated release of previously submitted patch.
It polish some part and extend ACL engine to match IP and PORT parsed in
HTTP request. (and take care of comments made by Willy ! ;))
Best regards,
Alexandre

parsing, so there's no I/O involved. They make it possible
to return custom error messages with custom status and headers.

Patch from Fabrice Dulaunoy. Explanation below, and script
merged in examples/.
This patch allow to put a different address in the check part for each
server (and not only a specific port)
I need this feature because I've a complex settings where, when a specific
farm goes down, I need to switch a set of other farm either if these other
farm behave perfectly well.
For that purpose, I've made a small PERL daemon with some REGEX or PORT
test which allow me to test a bunch of thing.
- fix critical bug introduced with 1.3.6 : an empty request header
may lead to a crash due to missing pointer assignment
- hdr_idx might be left uninitialized in debug mode
- fixed build on FreeBSD due to missing fd_set declaration
- stats now support the HEAD method too
- extracted http request from the session
- huge rework of the HTTP parser which is now a 28-state FSM.
- linux-style likely/unlikely macros for optimization hints
- do not create a server socket when there's no server
- added complete support and doc for TCP Splicing
- replaced the wait-queue linked list with an rbtree.
- stats: swap color sets for active and backup servers
- try to guess server check port when unset
- a few bugfixes and cleanups
The tcp-splicing code has been merged, and a doc has been written.
A configuration example has been derived from the previous content
switching sample.
Released 1.3.3 with the following changes :
- fix broken redispatch option in case the connection has already
been marked "in progress" (ie: nearly always).
- support regparm on x86 to speed up some often called functions
- removed a few useless calls to gettimeofday() in log functions.
- lots of 'const char*' cleanups
- turn every FD_* into functions which are faster on recent CPUs
- builds again on OpenBSD and Solaris
- started the changes towards I/O completion callbacks. stream_sock* have
replaced event_*.
- added the new "reqtarpit" and "reqitarpit" protection features
Released 1.3.1 with the following changes from 1.2.15 :
- now, haproxy warns about missing timeout during startup to try to
eliminate all those buggy configurations.
- added "Content-Type: text/html" in responses wherever appropriate, as
suggested by Cameron Simpson.
- implemented "option ssl-hello-chk" to use SSLv3 CLIENT HELLO messages to
test server's health
- implemented "monitor-uri" so that haproxy can reply to a specific URI with
an "HTTP/1.0 200 OK" response. This is useful to validate multiple proxies
at once.
This makes it possible to relay SSL connections in pure TCP instances while
ensuring the remote end really receives our data eventhough intermediate
agents (firewalls, proxies, ...) might acknowledge the connection.
Released 1.2.14 with the following changes :
- new HTML status report with the 'stats' keyword.
- added the 'abortonclose' option to better resist traffic surges
- implemented dynamic traffic regulation with the 'minconn' option
- show request time on denied requests
- definitely fixed hot reconf on OpenBSD by the use of SO_REUSEPORT
- now a proxy instance is allowed to run without servers, which is
useful to dedicate one instance to stats
- added lots of error counters
- a missing parenthesis preventd matching of cacheable cookies
- a missing parenthesis in poll_loop() might have caused missed events.
Summary of changes :
- 'maxconn' server parameter to do per-server session limitation
- queueing to support non-blocking session limitation
- fixed removal of cookies for cookie-less servers such as backup servers
- two separate wait queues for expirable and non-expirable tasks provide
better performance with lots of sessions.
- some code cleanups and performance improvements
- made state dumps a bit more verbose
- fixed missing checks for NULL srv in dispatch mode
- load balancing on backup servers was not possible in source hash mode.
- two session flags shared the same bit, but fortunately they were not
compatible.
* the time-out fix introduced in 1.1.25 caused a corner case where it was
possible for a client to keep a connection maintained regardless of the
timeout if the server closed the connection during the HEADER phase,
while the client ignored the close request while doing nothing in the
other direction. This has been fixed now by ensuring that read timeouts
are re-armed when switching to any SHUTW state.
* enhanced error reporting in the logs. Now the proxy will precisely detect
various error conditions related to the system and/or process limits, and
generate LOG_EMERG logs indicating that a resource has been exhausted.
* logs will contain two new characters for the error cause : 'R' indicates
a resource exhausted, and 'I' indicates an internal error, though this
one should never happen.
* server connection timeouts can now be reported in the logs (sC), as well
as connections refused because of maxconn limitations (PC).
* new global configuration keyword "ulimit-n" may be used to raise the FD
limit to usable values.
* a warning is now displayed on startup if the FD limit is lower than the
configured maximum number of sockets.
* new configuration keyword "monitor-net" makes it possible to be monitored
by external devices which connect to the proxy without being logged nor
forwarded to any server. Particularly useful on generic TCPv4 relays.
* fixed a bug where a TCP connection would be logged twice if the 'logasap'
option was enabled without the 'tcplog' option.
* encode_string() would use hdr_encode_map instead of the map argument.
* the logged request is now encoded with '#XX' for unprintable characters
* new keywords 'capture request header' and 'capture response header' enable
logging of arbitrary HTTP headers in requests and responses
* removed "-DSOLARIS" after replacing the last inet_aton() with inet_pton()
* added the '-V' command line option to verbosely report errors even though
the -q or 'quiet' options are specified. This is useful with '-c'.
* added a Red Hat init script and a .spec from Simon Matter <simon.matter@invoca.ch>
* added 'rspdeny' and 'rspideny' to block certain responses to avoid sensible
information leak from servers.
* more examples added into the configuration
* the configurable HTTP health check introduced in 1.1.23 revealed a shameful
bug : the code still assumed that HTTP requests were the same size as the
original ones (22 bytes), and failed if they were not.
* added support for pidfiles.
* if a client sent a full request then shut its write connection down, then
the request was aborted. This case was detected only when using haproxy
both as health-check client and as a server.
* if 'option httpchk' is used in a 'health' mode server, then responses will
change from 'OK' to 'HTTP/1.0 200 OK'.
* fixed a Linux-only bug in case of HTTP server health-checks, where a single
server response followed by a close could be ignored, and the server seen
as failed.
* renamed 'haproxy.txt' to 'haproxy-fr.txt'
* large documentation and examples cleanups
* 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
* 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.
* 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 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.
* 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().
