a1973c4d82 [CLEANUP] make makefile more old sh-friendly
Older SH on Solaris does not know about $(cmd) but only know `cmd`.

4f60f16dd3 [MAJOR] modularize the polling mechanisms
select, poll and epoll now have their dedicated functions and have
been split into distinct files. Several FD manipulation primitives
have been provided with each poller.

The rest of the code needs to be cleaned to remove traces of
StaticReadEvent/StaticWriteEvent. A trick involving a macro has
temporarily been used right now. Some work needs to be done to
factorize tests and sets everywhere.

42c7659669 [RELEASE] Released version 1.3.8.2 with the following changes :
- rewriting either the status line or request line could crash the
      process due to a pointer which ought to be reset before parsing.
    - rewriting the status line in the response did not work, it caused
      a 502 Bad Gateway due to an erroneous state during parsing

b38651a435 [MEDIUM] check for cttproxy support when required
Previously, use of the "usesrc" keyword could silently fail if
either the module was not loaded, or the user did not have enough
permissions. Now the errors are better diagnosed and more appropriate
advices are given.

964c936b04 [MAJOR] replace the wait-queue linked list with an rbtree.
This patch from Sin Yu makes use of an rbtree for the wait queue,
which will solve the slowdown problem encountered when timeouts
are heterogenous in the configuration. The next step will be to
turn maintain_proxies() into a per-proxy task so that we won't
have to scan them all after each poll() loop.

6620dbb47a [RELEASE] released 1.3.4
Released 1.3.4 with the following major changes :
    - support for cttproxy on the server side to present the client
      address to the server.
    - added support for SO_REUSEPORT on Linux (needs kernel patch)
    - new RFC2616-compliant HTTP request parser with header indexing
    - split proxies in frontends, rulesets and backends
    - implemented the 'req[i]setbe' to select a backend depending
      on the contents
    - added the 'default_backend' keyword to select a default BE.
    - new stats page featuring FEs and BEs + bytes in both dirs
    - improved log format to indicate the backend and the time in ms.
    - lots of cleanups

9bf6c6e24f [BUILD] makefile now detects and uses git to set the version
If git is found during the build process, then it will be used
to set the version, the commit number and the commit date. This
way, it will not be needed anymore to update the code to change
the version. The version is the last tag, and the commit number
is the number of commits since the last tag.

c21aa083df [BUILD] fixed the "git-tar" target in the Makefile
The git-tar target did not work correctly anymore, probably because
of a recent change in the output of "git-describe --tags". This is
now fixed.

e5f20dcea8 [MEDIUM] added the hdr_idx structure for future HTTP header indexing
This structure will consume 4 bytes per header to keep track of
headers within a request or a response without having to parse
the whole request for each regex. As it's not possible to allocate
only 4 bytes, we define a max number of HTTP headers. We set it
to (BUFSIZE+79)/80 so that 8kB buffers can contain 100 headers
(like Apache), resulting in 400 bytes dedicated to indexation,
or about 400/(2*8kB) ~= 2.4% of the memory usage.

77074d548b [MAJOR] support for source binding via cttproxy
Using the cttproxy kernel patch, it's possible to bind to any source
address. It is highly recommended to use the 03-natdel patch with the
other ones.

A new keyword appears as a complement to the "source" keyword : "usesrc".
The source address is mandatory and must be valid on the interface which
will see the packets. The "usesrc" option supports "client" (for full
client_ip:client_port spoofing), "client_ip" (for client_ip spoofing)
and any 'IP[:port]' combination to pretend to be another machine.

Right now, the source binding is missing from server health-checks if
set to another address. It must be implemented (think restricted firewalls).
The doc is still missing too.

9c9fea4617 [RELEASE] released 1.3.3
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

8f2b855ab2 [RELEASE] released 1.3.1 after resyncing with 1.2.15
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.

baaee00406 [BIGMOVE] exploded the monolithic haproxy.c file into multiple files.
The files are now stored under :
  - include/haproxy for the generic includes
  - include/types.h for the structures needed within prototypes
  - include/proto.h for function prototypes and inline functions
  - src/*.c for the C files

Most include files are now covered by LGPL. A last move still needs
to be done to put inline functions under GPL and not LGPL.

Version has been set to 1.3.0 in the code but some control still
needs to be done before releasing.

7e6328df2a [RELEASE] released 1.2.14
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.

9e1388671a [MEDIUM] added the new 'stats' keyword with user authentication subsystem.
Right now it only validates the user/passwd according to a specified list,
and lets the user pass through the proxy if the authentication is OK, and
it refuses any invalid access with a 401 Unauthorized response.

4404b7ebcc [RELEASE] released version 1.2.13.1
- an uninitialized field in the struct session could cause a crash when
     the session was freed. This has been encountered on Solaris only.
   - Solaris and OpenBSD no not support shutdown() on listening socket. Let's
     be nice to them by performing a soft stop if pause fails.

c3a2e0713f [RELEASE] released version 1.2.13
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.

b952e1db84 * released 1.2.7rc (1.1.33rc)
* second batch of socklen_t changes.
* clean-ups from Cameron Simpson.
* because tv_remain() does not know about eternity, using no timeout can
  make select() spin around a null time-out. Bug reported by Cameron Simpson.
* client read timeout was not properly set to eternity initialized after an
  accept() if it was not set in the config. It remained undetected so long
  because eternity is 0 and newly allocated pages are zeroed by the system.
* do not call get_original_dst() when not in transparent mode.
* implemented a workaround for a bug in certain epoll() implementations on
  linux-2.4 kernels (epoll-lt <= 0.21).
* implemented TCP keepalive with new options : tcpka, clitcpka, srvtcpka.

64a3cc3660 * released 1.2.5 (1.1.31)
* changed the runtime argument to disable epoll() to '-de'
* changed the runtime argument to disable poll() to '-dp'
* added global options 'nopoll' and 'noepoll' to do the same at the
  configuration level.
* added a 'linux24e' target to the Makefile for Linux 2.4 systems patched to
  support epoll().
* changed default FD_SETSIZE to 65536 on Solaris (default=1024)
* conditionned signals redirection to #ifdef DEBUG_MEMORY

1c2ad21e0f * released 1.2.5-pre4
* made epoll() support a compile-time option : ENABLE_EPOLL
* provided a very little libc replacement for a possibly missing epoll()
  implementation which can be enabled by -DUSE_MY_EPOLL
* implemented the poll() poller, which can be enabled with -DENABLE_POLL.
  The equivalent runtime argument becomes '-P'. A few tests show that it
  performs like select() with many fds, but slightly slower (certainly
  because of the higher amount of memory involved).
* separated the 3 polling methods and the tasks scheduler into 4 distinct
  functions which makes the code a lot more modular.
* moved some event tables to private static declarations inside the poller
  functions.
* the poller functions can now initialize themselves, run, and cleanup.
* changed the runtime argument to enable epoll() to '-E'.
* removed buggy epoll_ctl() code in the client_retnclose() function. This
  function was never meant to remove anything.
* fixed a typo which caused glibc to yell about a double free on exit.
* removed error checking after epoll_ctl(DEL) because we can never know if
  the fd is still active or already closed.
* added a few entries in the makefile

12350155a4 * released 1.2.4
* merged Alexander Lazic's and Klaus Wagner's work on application
  cookie-based persistence. Since this is the first merge, this version is
  not intended for general use and reports are more than welcome. Some
  documentation is really needed though.

0174f319a2 * released 1.2.3 (1.1.30)
* add an architecture guide to the documentation
* released without any changes
* increased default BUFSIZE to 16 kB to accept max headers of 8 kB which is
  compatible with Apache. This limit can be configured in the makefile now.
  Thanks to Eric Fehr for the checks.
* added a per-server "source" option which now makes it possible to bind to
  a different source for each (potentially identical) server.
* changed cookie-based server selection slightly to allow several servers to
  share a same cookie, thus making it possible to associate backup servers to
  live servers and ease soft-stop for maintenance periods. (Alexander Lazic)
* added the cookie 'prefix' mode which makes it possible to use persistence
  with thin clients which support only one cookie. The server name is prefixed
  before the application cookie, and restore back.
* fixed the order of servers within an instance to match documentation. Now
  the servers are *really* used in the order of their declaration. This is
  particularly important when multiple backup servers are in use.
2005-12-18 01:02:42 +01:00
willy tarreau
25c4ea505a * released 1.2.1-pre2
* add the "logasap" option which produces a log without waiting for the data
  to be transferred from the server to the client.
* add the "httpclose" option which removes any "connection:" header and adds
  "Connection: close" in both direction.
2005-12-18 00:49:49 +01:00
willy tarreau
eedaa9f220 * released 1.1.23
* 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

willy tarreau
a41a8b4ee6 * released 1.1.22
* '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
2005-12-17 14:02:24 +01:00
willy tarreau
2f6ba6579f * released 1.1.21
* 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
