3481c46368 * there was a bug in the way the backup servers were handled. They
were erroneously load-balanced while the doc said the opposite.
  Since load-balanced backup servers is one of the features some
  people have been asking for, the problem was fixed to reflect the
  documented behaviour and a new option 'allbackups' was introduced
  to provide the feature to those who need it.

1cec83c754 * a never ending connect() could lead to a fast select() loop if
its timeout times the number of retransmits exceeded the server
  read or write timeout, because the later was used to compute
  select()'s timeout while the connection timeout was not reached.

c9a643998f * fixed some tv_cmp_ms() computations. Strictly speaking, there was
a very short window of 1 microsecond every millisecond during which
  two events were not considered as 1 ms apart from each other.

a9e75f6eff * now we initialize the libc's localtime structures very early so
that even under OOM conditions, we can still send dated error
  messages without segfaulting.

e78ae269fe * fixed a nasty bug in epoll_loop() and poll_loop() by which an EPOLL_HUP event
could trigger both a read and a write calls, thus sometimes inducing headers
  being directly sent from srv to cli without modification, and leading further
  modification to crash the process by memory corruption, because
  rep.data+rep.l<rep.h so the memmove() length argument is negative. Only
  observed with epoll() and never poll(), though this one should have been
  affected too. Now, only call functions which have been allowed to.

a4a583ac05 * TCP health-checks don't detect a connection refused with poll/epoll
because event_srv_chk_r() is called before _w() and flushes the socket
  error. The result is that the server remains UP. The problem only
  affects pure TCP health-checks when select() is disabled. You may
  encounter this on SSL or SMTP proxies.

48b06594b9 * The 'retries' option was not used because the connect() could not return
an error if the connection was refused before the the timeout. So the
  client was sent to the server anyway and then got its connection broken
  because of the write error. This is not a real problem with persistence,
  but it definitely is for new clients. This stupid bug must have been
  present for years !

d0fb4650d6 * delayed the quiet mode during startup so that most of the startup alerts can

77bc854117 * building with -DUSE_PCRE should include PCRE headers and not regex.h. At
least on Solaris, this caused the libc's regex primitives to be used instead
  of PCRE, which caused trouble on group references. This is now fixed.

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.

0fe396592d * released 1.2.6-pre5 (1.1.32)

willy tarreau
b1285d5ce0 * released 1.2.6-pre4
* 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.

08dedbe898 * released 1.2.5.1
* dirty hack to fix a bug introduced with epoll : if we close an FD and
  immediately reassign it to another session through a connect(), the
  Prev{Read,Write}Events are not updated, which causes trouble detecting
  changes, thus leading to many timeouts at high loads.

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

ad90a0c80e * released 1.2.5-pre3

c1f4753d60 * released 1.2.5-pre2
* implemented the HTTP 303 code for error redirection. This forces the
  browser to fetch the given URI with a GET request. The new keyword for
  this is 'errorloc303', and a new 'errorloc302' keyword has been created
  to make them easily distinguishable.
* added more controls in the parser for valid use of '\x' sequence.
* few fixes from Alex & Klaus
* fixed a few errors in the documentation
* do not pre-initialize unused file-descriptors before select() anymore.

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.

4302f49525 * released 1.2.2 (1.1.29)
* 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()

982249e9e7 * released 1.2.1 (1.1.28)
* 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
2005-12-18 00:57:06 +01:00
willy tarreau
97f58576eb * added the 'checkcache' option which blocks cacheable responses containing

2005-12-18 00:53:44 +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.

fe2c5c147b * released 1.1.27
* 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.

willy tarreau
c58fc6943d * released 1.1.26
* the fix introduced in 1.1.25 for client timeouts while waiting for servers
  broke almost all compatibility with POST requests, because the proxy
  stopped to read anything from the client as soon as it got all of its
  headers.

c1cae63922 * released 1.1.25
* added the 'tcplog' option, which provides enhanced, HTTP-like logs for
  generic TCP proxies, or lighter logs for HTTP proxies.
* fixed a time-out condition wrongly reported as client time-out in data
  phase if the client timeout was lower than the connect timeout times the
  number of retries.
* doc: added some precisions about the log timers

197e8ec2c3 * released 1.1.24
* 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

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

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
