- removed a few useless calls to gettimeofday() in log functions.
- lots of 'const char*' cleanups

- 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.
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.
- 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.
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.
be displayed even in quiet mode.
* display an alert when a listener has no address, invalid or no port, or when
there are no enabled listeners upon startup.
* 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.
* 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.
* 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.
* 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
* 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
* 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.
* 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.
* 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.
* 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
