2585 - several minor optimizations
2586

2597 - fixed rare bug occuring on TCP with early close (reported by Andy Smith)
2598 - implemented URI hashing algorithm (Guillaume Dallaire)
2599 - implemented SMTP health checks (Peter van Dijk)
2600 - replaced the rbtree with ul2tree from old scheduler project

2610 - modularized the polling mechanisms and use function pointers instead
2611 of macros at many places
2612 - implemented support for FreeBSD's kqueue() polling mechanism
2613 - fixed a warning on OpenBSD : MIN/MAX redefined
2614 - change socket registration order at startup to accomodate kqueue.
2615 - several makefile cleanups to support old shells
2616 - fix build with limits.h once for all
2617 - ev_epoll: do not rely on fd_sets anymore, use changes stacks instead.
2618 - fdtab now holds the results of polling
2619 - implemented support for speculative I/O processing with epoll()
2620 - remove useless calls to shutdown(SHUT_RD), resulting in small speed boost
2621 - auto-registering of pollers at load time
2622
Willy Tarreau42c76592007-04-03 20:30:13 +020026232007/04/03 : 1.3.8.2
2624 - rewriting either the status line or request line could crash the
2625 process due to a pointer which ought to be reset before parsing.
2626 - rewriting the status line in the response did not work, it caused
2627 a 502 Bad Gateway due to an erroneous state during parsing
2628
Willy Tarreauef6d7612007-04-01 11:06:22 +020026292007/04/01 : 1.3.8.1

2637 - fixed several bugs which might have caused a crash with bad configs
2638 - several optimizations in header processing
2639 - many progresses towards transaction-based processing
2640 - option forwardfor may be used in frontends

2648 - added the "except" keyword to the "forwardfor" option (Bryan German)
2649 - support for health-checks on other addresses (Fabrice Dulaunoy)
2650 - makefile for MacOS 10.4 / Darwin (Dan Zinngrabe)
2651 - do not insert "Connection: close" in HTTP/1.0 messages
2652
Willy Tarreau9cabf702007-01-26 23:49:01 +010026532007/01/26 : 1.3.7
2654 - fix critical bug introduced with 1.3.6 : an empty request header
2655 may lead to a crash due to missing pointer assignment
2656 - hdr_idx might be left uninitialized in debug mode
2657 - fixed build on FreeBSD due to missing fd_set declaration
2658
Willy Tarreaue7a24382007-01-22 08:57:44 +010026592007/01/22 : 1.3.6.1
2660 - change in the header chaining broke cookies and authentication
2661
Willy Tarreau49e1ee82007-01-22 00:56:46 +010026622007/01/22 : 1.3.6
2663 - stats now support the HEAD method too
2664 - extracted http request from the session
2665 - huge rework of the HTTP parser which is now a 28-state FSM.
2666 - linux-style likely/unlikely macros for optimization hints
2667 - do not create a server socket when there's no server
2668 - imported lots of docs
2669
Willy Tarreau5871f8e2007-01-07 02:47:01 +010026702007/01/07 : 1.3.5
2671 - stats: swap color sets for active and backup servers
2672 - try to guess server check port when unset
2673 - added complete support and doc for TCP Splicing
2674 - replace the wait-queue linked list with an rbtree.
2675 - a few bugfixes and cleanups
2676
Willy Tarreau85270da2007-01-02 00:59:39 +010026772007/01/02 : 1.3.4
2678 - support for cttproxy on the server side to present the client
2679 address to the server.
2680 - added support for SO_REUSEPORT on Linux (needs kernel patch)
2681 - new RFC2616-compliant HTTP request parser with header indexing
2682 - split proxies in frontends, rulesets and backends
2683 - implemented the 'req[i]setbe' to select a backend depending
2684 on the contents
2685 - added the 'default_backend' keyword to select a default BE.
2686 - new stats page featuring FEs and BEs + bytes in both dirs
2687 - improved log format to indicate the backend and the time in ms.
2688 - lots of cleanups
2689
Willy Tarreau9c9fea42006-10-16 00:03:35 +020026902006/10/15 : 1.3.3
2691 - fix broken redispatch option in case the connection has already
2692 been marked "in progress" (ie: nearly always).
2693 - support regparm on x86 to speed up some often called functions
2694 - removed a few useless calls to gettimeofday() in log functions.
2695 - lots of 'const char*' cleanups
2696 - turn every FD_* into functions which are faster on recent CPUs
2697
Willy Tarreau690f9aa2006-09-03 11:23:06 +020026982006/09/03 : 1.3.2
2699 - started the changes towards I/O completion callbacks. stream_sock* have
2700 replaced event_*.
2701 - added the new "reqtarpit" and "reqitarpit" protection features
2702
Willy Tarreau8f2b8552006-07-09 17:11:39 +020027032006/07/09 : 1.3.1 (1.2.15)
2704 - now, haproxy warns about missing timeout during startup to try to
2705 eliminate all those buggy configurations.
2706 - added "Content-Type: text/html" in responses wherever appropriate, as
2707 suggested by Cameron Simpson.
2708 - implemented "option ssl-hello-chk" to use SSLv3 CLIENT HELLO messages to
2709 test server's health
2710 - implemented "monitor-uri" so that haproxy can reply to a specific URI with
2711 an "HTTP/1.0 200 OK" response. This is useful to validate multiple proxies
2712 at once.
2713
Willy Tarreaub9e98b62006-07-03 10:32:46 +020027142006/06/29 : 1.3.0
2715 - exploded the whole file into multiple .c and .h. No functionnal
Willy Tarreau8f2b8552006-07-09 17:11:39 +02002716 difference is expected at all.
2717 - fixed a bug by which neither stats nor error messages could be returned if
2718 'clitimeout' was missing.
Willy Tarreaub9e98b62006-07-03 10:32:46 +02002719
willy tarreau7e6328d2006-05-21 23:26:20 +020027202006/05/21 : 1.2.14
2721 - new HTML status report with the 'stats' keyword.
2722 - added the 'abortonclose' option to better resist traffic surges
2723 - implemented dynamic traffic regulation with the 'minconn' option
2724 - show request time on denied requests
2725 - definitely fixed hot reconf on OpenBSD by the use of SO_REUSEPORT
2726 - now a proxy instance is allowed to run without servers, which is
2727 useful to dedicate one instance to stats
2728 - added lots of error counters
2729 - a missing parenthesis preventd matching of cacheable cookies
2730 - a missing parenthesis in poll_loop() might have caused missed events.
2731
Willy TARREAU4404b7e2006-05-14 10:00:09 +020027322006/05/14 : 1.2.13.1
2733 - an uninitialized field in the struct session could cause a crash when
2734 the session was freed. This has been encountered on Solaris only.
2735 - Solaris and OpenBSD no not support shutdown() on listening socket. Let's
2736 be nice to them by performing a soft stop if pause fails.
2737
willy tarreauc3a2e072006-05-13 18:51:38 +020027382006/05/13 : 1.2.13
2739 - 'maxconn' server parameter to do per-server session limitation
2740 - queueing to support non-blocking session limitation
2741 - fixed removal of cookies for cookie-less servers such as backup servers
2742 - two separate wait queues for expirable and non-expirable tasks provide
2743 better performance with lots of sessions.
2744 - some code cleanups and performance improvements
2745 - made state dumps a bit more verbose
2746 - fixed missing checks for NULL srv in dispatch mode
2747 - load balancing on backup servers was not possible in source hash mode.
2748 - two session flags shared the same bit, but fortunately they were not
2749 compatible.
2750
willy tarreauc0d4bbd2006-04-15 21:47:50 +020027512006/04/15 : 1.2.12
2752 Very few changes preparing for more important changes to support per-server
2753 session limitations and queueing :
2754 - ignore leading empty lines in HTTP requests as suggested by RFC2616.
2755 - added the 'weight' parameter to the servers, limited to 1..256. It applies
2756 to roundrobin and source hash.
2757 - the optional '-s' option could clobber '-st' and '-sf' if compiled in.
2758
willy tarreaue0dd2692006-03-30 16:27:34 +020027592006/03/30 : 1.2.11.1
2760 - under some conditions, it might have been possible that when the
2761 last dead server became available, it would not have been used
2762 till another one would have changed state. Could not be reproduced
2763 at all, however seems possible from the code.
2764
willy tarreaud2058dc2006-03-25 20:35:41 +010027652006/03/25 : 1.2.11
2766 - added the '-db' command-line option to disable backgrounding.
2767 - added the -sf/-st command-line arguments which are used to specify
2768 a list of pids to send a FINISH or TERMINATE signal upon startup.
2769 They will also be asked to release their port if a bind fails.
2770 - reworked the startup mechanism to allow the sending of a signal to a list
2771 of old pids if a socket cannot be bound, with a retry for a limited amount
2772 of time (1 second by default).
2773 - added the ability to enforce limits on memory usage.
2774 - added the 'source' load-balancing algorithm which uses the source IP(v4|v6)
2775 - re-architectured the server round-robin mechanism to ease integration of
2776 other algorithms. It now relies on the number of active and backup servers.
2777 - added a counter for the number of active and backup servers, and report
2778 these numbers upon SIGHUP or state change.
2779
willy tarreaubfad5742006-03-23 14:19:11 +010027802006/03/23 : 1.2.10.1
2781 - while fixing the backup server round-robin "feature", a new bug was
2782 introduced which could miss some backup servers.
2783 - the displayed proxy name was wrong when dumping upon SIGHUP.
2784
willy tarreauaaff30e2006-03-19 21:30:41 +010027852006/03/19 : 1.2.10
2786 - assert.h is needed when DEBUG is defined.
2787 - ENORMOUS long standing bug affecting the epoll polling system :
2788 event_data is a union, not a structure !
2789 - Make fd management more robust and easier to debug. Also some
2790 micro-optimisations.
2791 - Limit the number of consecutive accept() in multi-process mode.
2792 This produces a more evenly distributed load across the processes and
2793 slightly improves performance by reducing bottlenecks.
2794 - Make health-checks be more regular, and faster to retry after a timeout.
2795 - Fixed some messages to ease parsing of alerts.
2796 - provided a patch to enable epoll on RHEL3 kernels.
2797 - Separated OpenBSD build from the main Makefile into a new one.
2798
willy tarreau50be0172006-03-15 19:41:19 +010027992006/03/15 : 1.2.9
2800 - haproxy could not be stopped after being paused, it had to be woken up
2801 first. This has been fixed.
2802 - the 'ulimit-n' parameter is now optional and by default computed from
2803 maxconn + the number of listeners + the number of health-checks.
2804 - it is now possible to specify a maximum number of connections at build
2805 time with the SYSTEM_MAXCONN define. The value set in the configuration
2806 file will then be limited to this value, and only the command-line '-n'
2807 option will be able to bypass it. It will prevent against accidental
2808 high memory usage on small systems.
2809 - RFC2616 expects that any HTTP agent accepts multi-line headers. Earlier
2810 versions did not detect a line beginning with a space as the continuation
2811 of previous header. It is now correct.
2812 - health checks sent to servers configured with identical intervals were
2813 sent in perfect synchronisation because the initial time was the same
2814 for all. This could induce high load peaks when fragile servers were
2815 hosting tens of instances for the same application. Now the load is
2816 spread evenly across the smallest interval amongst a listener.
2817 - a new 'forceclose' option was added to make the proxy close the outgoing
2818 channel to the server once it has sent all its headers and the server
2819 starts responding. This helps some servers which don't close upon the
2820 'Connection: close' header. It implies 'option httpclose'.
2821 - there was a bug in the way the backup servers were handled. They were
2822 erroneously load-balanced while the doc said the opposite. Since
2823 load-balanced backup servers is one of the features some people have
2824 been asking for, the problem was fixed to reflect the documented
2825 behaviour and a new option 'allbackups' was introduced to provide the
2826 feature to those who need it.
2827 - a never ending connect() could lead to a fast select() loop if its
2828 timeout times the number of retransmits exceeded the server read or write
2829 timeout, because the later was used to compute select()'s timeout while
2830 the connection timeout was not reached.
2831 - now we initialize the libc's localtime structures very early so that even
2832 under OOM conditions, we can still send dated error messages without
2833 segfaulting.
2834 - the 'daemon' mode implies 'quiet' and disables 'verbose' because file
2835 descriptors are closed.
2836
willy tarreau065f1c02006-01-29 22:10:07 +010028372006/01/29 : 1.2.8
2838 - fixed a nasty bug affecting poll/epoll which could return unmodified data
2839 from the server to the client, and sometimes lead to memory corruption
2840 crashing the process.
2841 - added the new pause/play mechanism with SIGTTOU/SIGTTIN for hot-reconf.
2842
28432005/12/18 : 1.2.7.1
2844 - the "retries" option was ignored because connect() could not return an
2845 error if the connection failed before the timeout.
2846 - TCP health-checks could not detect a connection refused in poll/epoll
2847 mode.
2848
willy tarreaua56eca72005-12-18 01:34:42 +010028492005/11/13 : 1.2.7
willy tarreau77bc8542005-12-18 01:31:43 +01002850 - building with -DUSE_PCRE should include PCRE headers and not regex.h. At
2851 least on Solaris, this caused the libc's regex primitives to be used instead
2852 of PCRE, which caused trouble on group references. This is now fixed.
willy tarreaud0fb4652005-12-18 01:32:04 +01002853 - delayed the quiet mode during startup so that most of the startup alerts can
2854 be displayed even in quiet mode.
2855 - display an alert when a listener has no address, invalid or no port, or when
2856 there are no enabled listeners upon startup.
willy tarreau4373b962005-12-18 01:32:31 +01002857 - added "static-pcre" to the list of supported regex options in the Makefile.
willy tarreau77bc8542005-12-18 01:31:43 +01002858
willy tarreaub952e1d2005-12-18 01:31:20 +010028592005/10/09 : 1.2.7rc (1.1.33rc)
2860 - second batch of socklen_t changes.
2861 - clean-ups from Cameron Simpson.
2862 - because tv_remain() does not know about eternity, using no timeout can
2863 make select() spin around a null time-out. Bug reported by Cameron Simpson.
2864 - client read timeout was not properly set to eternity initialized after an
2865 accept() if it was not set in the config. It remained undetected so long
2866 because eternity is 0 and newly allocated pages are zeroed by the system.
2867 - do not call get_original_dst() when not in transparent mode.
2868 - implemented a workaround for a bug in certain epoll() implementations on
2869 linux-2.4 kernels (epoll-lt <= 0.21).
2870 - implemented TCP keepalive with new options : tcpka, clitcpka, srvtcpka.
2871
willy tarreauc5f73ed2005-12-18 01:26:38 +010028722005/08/07 : 1.2.6
2873 - clean-up patch from Alexander Lazic fixes build on Debian 3.1 (socklen_t).
2874
28752005/07/06 : 1.2.6-pre5 (1.1.32)
willy tarreau0fe39652005-12-18 01:25:24 +01002876 - added the number of active sessions (proxy/process) in the logs
2877
28782005/07/06 : 1.2.6-pre4 (1.1.32-pre4)
willy tarreaub1285d52005-12-18 01:20:14 +01002879 - the time-out fix introduced in 1.1.25 caused a corner case where it was
2880 possible for a client to keep a connection maintained regardless of the
2881 timeout if the server closed the connection during the HEADER phase,
2882 while the client ignored the close request while doing nothing in the
2883 other direction. This has been fixed now by ensuring that read timeouts
2884 are re-armed when switching to any SHUTW state.
2885
28862005/07/05 : 1.2.6-pre3 (1.1.32-pre3)
2887 - enhanced error reporting in the logs. Now the proxy will precisely detect
2888 various error conditions related to the system and/or process limits, and
2889 generate LOG_EMERG logs indicating that a resource has been exhausted.
2890 - logs will contain two new characters for the error cause : 'R' indicates
2891 a resource exhausted, and 'I' indicates an internal error, though this
2892 one should never happen.
2893 - server connection timeouts can now be reported in the logs (sC), as well
2894 as connections refused because of maxconn limitations (PC).
2895
28962005/07/05 : 1.2.6-pre2 (1.1.32-pre2)
2897 - new global configuration keyword "ulimit-n" may be used to raise the FD
2898 limit to usable values.
2899 - a warning is now displayed on startup if the FD limit is lower than the
2900 configured maximum number of sockets.
2901
29022005/07/05 : 1.2.6-pre1 (1.1.32-pre1)
2903 - new configuration keyword "monitor-net" makes it possible to be monitored
2904 by external devices which connect to the proxy without being logged nor
2905 forwarded to any server. Particularly useful on generic TCPv4 relays.
2906
willy tarreau5dffb602005-12-18 01:15:23 +010029072005/06/21 : 1.2.5.2
2908 - fixed build on PPC where chars are unsigned by default
2909
willy tarreau08dedbe2005-12-18 01:13:48 +010029102005/05/02 : 1.2.5.1
2911 - dirty hack to fix a bug introduced with epoll : if we close an FD and
2912 immediately reassign it to another session through a connect(), the
2913 Prev{Read,Write}Events are not updated, which causes trouble detecting
2914 changes, thus leading to many timeouts at high loads.
2915
willy tarreau64a3cc32005-12-18 01:13:11 +010029162005/04/30 : 1.2.5 (1.1.31)
2917 - changed the runtime argument to disable epoll() to '-de'
2918 - changed the runtime argument to disable poll() to '-dp'
2919 - added global options 'nopoll' and 'noepoll' to do the same at the
2920 configuration level.
2921 - added a 'linux24e' target to the Makefile for Linux 2.4 systems patched to
2922 support epoll().
2923 - changed default FD_SETSIZE to 65536 on Solaris (default=1024)
2924 - conditionned signals redirection to #ifdef DEBUG_MEMORY
2925
willy tarreau1c2ad212005-12-18 01:11:29 +010029262005/04/26 : 1.2.5-pre4
2927 - made epoll() support a compile-time option : ENABLE_EPOLL
2928 - provided a very little libc replacement for a possibly missing epoll()
2929 implementation which can be enabled by -DUSE_MY_EPOLL
2930 - implemented the poll() poller, which can be enabled with -DENABLE_POLL.
2931 The equivalent runtime argument becomes '-P'. A few tests show that it
2932 performs like select() with many fds, but slightly slower (certainly
2933 because of the higher amount of memory involved).
2934 - separated the 3 polling methods and the tasks scheduler into 4 distinct
2935 functions which makes the code a lot more modular.
2936 - moved some event tables to private static declarations inside the poller
2937 functions.
2938 - the poller functions can now initialize themselves, run, and cleanup.
2939 - changed the runtime argument to enable epoll() to '-E'.
2940 - removed buggy epoll_ctl() code in the client_retnclose() function. This
2941 function was never meant to remove anything.
2942 - fixed a typo which caused glibc to yell about a double free on exit.
2943 - removed error checking after epoll_ctl(DEL) because we can never know if
2944 the fd is still active or already closed.
2945 - added a few entries in the makefile
2946
willy tarreauad90a0c2005-12-18 01:09:15 +010029472005/04/25 : 1.2.5-pre3
2948 - experimental epoll() support (use temporary '-e' argument)
2949
29502005/04/24 : 1.2.5-pre2
willy tarreauc1f47532005-12-18 01:08:26 +01002951 - implemented the HTTP 303 code for error redirection. This forces the
2952 browser to fetch the given URI with a GET request. The new keyword for
2953 this is 'errorloc303', and a new 'errorloc302' keyword has been created
2954 to make them easily distinguishable.
2955 - added more controls in the parser for valid use of '\x' sequence.
2956 - few fixes from Alex & Klaus
2957
willy tarreauad90a0c2005-12-18 01:09:15 +010029582005/02/17 : 1.2.5-pre1
willy tarreauc1f47532005-12-18 01:08:26 +01002959 - fixed a few errors in the documentation
2960
29612005/02/13
2962 - do not pre-initialize unused file-descriptors before select() anymore.
2963
willy tarreau12350152005-12-18 01:03:27 +010029642005/01/22 : 1.2.4
2965 - merged Alexander Lazic's and Klaus Wagner's work on application
2966 cookie-based persistence. Since this is the first merge, this version is
2967 not intended for general use and reports are more than welcome. Some
2968 documentation is really needed though.
2969
willy tarreau0174f312005-12-18 01:02:42 +010029702005/01/22 : 1.2.3 (1.1.30)
2971 - add an architecture guide to the documentation
2972 - released without any changes
2973
29742004/12/26 : 1.2.3-pre1 (1.1.30-pre1)
2975 - increased default BUFSIZE to 16 kB to accept max headers of 8 kB which is
2976 compatible with Apache. This limit can be configured in the makefile now.
2977 Thanks to Eric Fehr for the checks.
2978 - added a per-server "source" option which now makes it possible to bind to
2979 a different source for each (potentially identical) server.
2980 - changed cookie-based server selection slightly to allow several servers to
2981 share a same cookie, thus making it possible to associate backup servers to
2982 live servers and ease soft-stop for maintenance periods. (Alexander Lazic)
2983 - added the cookie 'prefix' mode which makes it possible to use persistence
2984 with thin clients which support only one cookie. The server name is prefixed
2985 before the application cookie, and restore back.
2986 - fixed the order of servers within an instance to match documentation. Now
2987 the servers are *really* used in the order of their declaration. This is
2988 particularly important when multiple backup servers are in use.
2989
willy tarreau4302f492005-12-18 01:00:37 +010029902004/10/18 : 1.2.2 (1.1.29)
2991 - fixed a bug where a TCP connection would be logged twice if the 'logasap'
2992 option was enabled without the 'tcplog' option.
2993 - encode_string() would use hdr_encode_map instead of the map argument.
2994
29952004/08/10 : (1.1.29-pre2)
2996 - the logged request is now encoded with '#XX' for unprintable characters
2997 - new keywords 'capture request header' and 'capture response header' enable
2998 logging of arbitrary HTTP headers in requests and responses
2999 - removed "-DSOLARIS" after replacing the last inet_aton() with inet_pton()
3000
willy tarreau982249e2005-12-18 00:57:06 +010030012004/06/06 : 1.2.1 (1.1.28)
3002 - added the '-V' command line option to verbosely report errors even though
3003 the -q or 'quiet' options are specified. This is useful with '-c'.
3004 - added a Red Hat init script and a .spec from Simon Matter <simon.matter@invoca.ch>
willy tarreau036e1ce2005-12-17 13:46:33 +01003005
willy tarreau982249e2005-12-18 00:57:06 +010030062004/06/05 :
3007 - added the "logasap" option which produces a log without waiting for the data
3008 to be transferred from the server to the client.
3009 - added the "httpclose" option which removes any "connection:" header and adds
3010 "Connection: close" in both direction.
willy tarreau97f58572005-12-18 00:53:44 +01003011 - added the 'checkcache' option which blocks cacheable responses containing
3012 dangerous headers, such as 'set-cookie'.
willy tarreau982249e2005-12-18 00:57:06 +01003013 - added 'rspdeny' and 'rspideny' to block certain responses to avoid sensible
3014 information leak from servers.
willy tarreau25c4ea52005-12-18 00:49:49 +01003015
30162004/04/18 :
willy tarreaudd07e972005-12-18 00:48:48 +01003017 - send an EMERG log when no server is available for a given proxy
3018 - added the '-c' command line option to syntactically check the
3019 configuration file without starting the service.
3020
willy tarreau8a86dbf2005-12-18 00:45:59 +010030212003/11/09 : 1.2.0
3022 - the same as 1.1.27 + IPv6 support on the client side
3023
willy tarreaufe2c5c12005-12-17 14:14:34 +010030242003/10/27 : 1.1.27
3025 - the configurable HTTP health check introduced in 1.1.23 revealed a shameful
3026 bug : the code still assumed that HTTP requests were the same size as the
3027 original ones (22 bytes), and failed if they were not.
3028 - added support for pidfiles.
3029
willy tarreauc58fc692005-12-17 14:13:08 +010030302003/10/22 : 1.1.26
3031 - the fix introduced in 1.1.25 for client timeouts while waiting for servers
3032 broke almost all compatibility with POST requests, because the proxy
3033 stopped to read anything from the client as soon as it got all of its
3034 headers.
3035
willy tarreauc1cae632005-12-17 14:12:23 +010030362003/10/15 : 1.1.25
3037 - added the 'tcplog' option, which provides enhanced, HTTP-like logs for
3038 generic TCP proxies, or lighter logs for HTTP proxies.
3039 - fixed a time-out condition wrongly reported as client time-out in data
3040 phase if the client timeout was lower than the connect timeout times the
3041 number of retries.
3042
willy tarreau197e8ec2005-12-17 14:10:59 +010030432003/09/21 : 1.1.24
3044 - if a client sent a full request then shut its write connection down, then
3045 the request was aborted. This case was detected only when using haproxy
3046 both as health-check client and as a server.
3047 - if 'option httpchk' is used in a 'health' mode server, then responses will
3048 change from 'OK' to 'HTTP/1.0 200 OK'.
3049 - fixed a Linux-only bug in case of HTTP server health-checks, where a single
3050 server response followed by a close could be ignored, and the server seen
3051 as failed.
3052
willy tarreaueedaa9f2005-12-17 14:08:03 +010030532003/09/19 : 1.1.23
3054 - fixed a stupid bug introduced in 1.1.22 which caused second and subsequent
3055 'default' sections to keep previous parameters, and not initialize logs
3056 correctly.
3057 - fixed a second stupid bug introduced in 1.1.22 which caused configurations
3058 relying on 'dispatch' mode to segfault at the first connection.
3059 - 'option httpchk' now supports method, HTTP version and a few headers.
3060 - now, 'option httpchk', 'cookie' and 'capture' can be specified in
3061 'defaults' section
3062
30632003/09/10 : 1.1.22
willy tarreaua41a8b42005-12-17 14:02:24 +01003064 - 'listen' now supports optionnal address:port-range lists
3065 - 'bind' introduced to add new listen addresses
3066 - fixed a bug which caused a session to be kept established on a server till
3067 it timed out if the client closed during the DATA phase.
3068 - the port part of each server address can now be empty to make the proxy
3069 connect to the server on the same port it was connected to, be an absolute
3070 unsigned number to reflect a single port (as in older versions), or an
3071 explicitly signed number (+N/-N) to indicate that this offset must be
3072 applied to the port the proxy was connected to, when connecting to the
3073 server.
3074 - the 'port' server option allows the user to specify a different
3075 health-check port than the service one. It is mandatory when only relative
3076 ports have been specified and check is required. By default, the checks are
3077 sent to the service port.
3078 - new 'defaults' section which is rather similar to 'listen' except that all
3079 values are only used as default values for future 'listen' sections, until
3080 a new 'defaults' resets them. At the moment, server options, regexes,
3081 cookie names and captures cannot be set in the 'defaults' section.
3082
willy tarreau2f6ba652005-12-17 13:57:42 +010030832003/05/06 : 1.1.21
3084 - changed the debug output format so that it now includes the session unique
3085 ID followed by the instance name at the beginning of each line.
3086 - in debug mode, accept now shows the client's IP and port.
3087 - added one 3 small debugging scripts to search and pretty print debug output
3088 - changed the default health check request to "OPTIONS /" instead of
3089 "OPTIONS *" since not all servers implement the later one.
3090 - "option httpchk" now accepts an optional parameter allowing the user to
3091 specify and URI other than '/' during health-checks.
3092
willy tarreaub1ff9db2005-12-17 13:51:03 +010030932003/04/21 : 1.1.20
3094 - fixed two problems with time-outs, one where a server would be logged as
3095 timed out during transfer that take longer to complete than the fixed
3096 time-out, and one where clients were logged as timed-out during the data
3097 phase because they didn't have anything to send. This sometimes caused
3098 slow client connections to close too early while in fact there was no
3099 problem. The proper fix would be to have a per-fd time-out with
3100 conditions depending on the state of the HTTP FSM.
3101
willy tarreau906b2682005-12-17 13:49:52 +010031022003/04/16 : 1.1.19
3103 - haproxy was NOT RFC compliant because it was case-sensitive on HTTP
3104 "Cookie:" and "Set-Cookie:" headers. This caused JVM 1.4 to fail on
3105 cookie persistence because it uses "cookie:". Two memcmp() have been
3106 replaced with strncasecmp().
3107
willy tarreau036e1ce2005-12-17 13:46:33 +010031082003/04/02 : 1.1.18
3109 - Haproxy can be compiled with PCRE regex instead of libc regex, by setting
3110 REGEX=pcre on the make command line.
3111 - HTTP health-checks now use "OPTIONS *" instead of "OPTIONS /".
3112 - when explicit source address binding is required, it is now also used for
3113 health-checks.
3114 - added 'reqpass' and 'reqipass' to allow certain headers but not the request
3115 itself.
3116 - factored several strings to reduce binary size by about 2 kB.
3117 - replaced setreuid() and setregid() with more standard setuid() and setgid().
3118 - added 4 status flags to the log line indicating who ended the connection
3119 first, the sessions state, the validity of the cookie, and action taken on
3120 the set-cookie header.
3121
31222002/10/18 : 1.1.17
3123 - add the notion of "backup" servers, which are used only when all other
3124 servers are down.
3125 - make Set-Cookie return "" instead of "(null)" when the server has no
3126 cookie assigned (useful for backup servers).
3127 - "log" now supports an optionnal level name (info, notice, err ...) above
3128 which nothing is sent.
3129 - replaced some strncmp() with memcmp() for better efficiency.
3130 - added "capture cookie" option which logs client and/or server cookies
3131 - cleaned up/down messages and dump servers states upon SIGHUP
3132 - added a redirection feature for errors : "errorloc <errnum> <url>"
3133 - now we won't insist on connecting to a dead server, even with a cookie,
3134 unless option "persist" is specified.
3135 - added HTTP/408 response for client request time-out and HTTP/50[234] for
3136 server reply time-out or errors.
3137
31382002/09/01 : 1.1.16
3139 - implement HTTP health checks when option "httpchk" is specified.
3140
31412002/08/07 : 1.1.15
3142 - replaced setpgid()/setpgrp() with setsid() for better portability, because
3143 setpgrp() doesn't have the same meaning under Solaris, Linux, and OpenBSD.
3144
31452002/07/20 : 1.1.14
3146 - added "postonly" cookie mode
3147
31482002/07/15 : 1.1.13
3149 - tv_diff used inverted parameters which led to negative times !
3150
31512002/07/13 : 1.1.12
3152 - fixed stats monitoring, and optimized some tv_* for most common cases.
3153 - replaced temporary 'newhdr' with 'trash' to reduce stack size
3154 - made HTTP errors more HTML-fiendly.
3155 - renamed strlcpy() to strlcpy2() because of a slightly difference between
3156 their behaviour (return value), to avoid confusion.
3157 - restricted HTTP messages to HTTP proxies only
3158 - added a 502 message when the connection has been refused by the server,
3159 to prevent clients from believing this is a zero-byte HTTP 0.9 reply.
3160 - changed 'Cache-control:' from 'no-cache="set-cookie"' to 'private' when
3161 inserting a cookie, because some caches (apache) don't understand it.
3162 - fixed processing of server headers when client is in SHUTR state
3163
31642002/07/04 :
3165 - automatically close fd's 0,1 and 2 when going daemon ; setpgrp() after
3166 setpgid()
3167
31682002/06/04 : 1.1.11
3169 - fixed multi-cookie handling in client request to allow clean deletion
3170 in insert+indirect mode. Now, only the server cookie is deleted and not
willy tarreau906b2682005-12-17 13:49:52 +01003171 all the header. Should now be compliant to RFC2965.
willy tarreau036e1ce2005-12-17 13:46:33 +01003172 - added a "nocache" option to "cookie" to specify that we explicitly want
3173 to add a "cache-control" header when we add a cookie.
3174 It is also possible to add an "Expires: <old-date>" to keep compatibility
3175 with old/broken caches.
3176
31772002/05/10 : 1.1.10
3178 - if a cookie is used in insert+indirect mode, it's desirable that the
3179 the servers don't see it. It was not possible to remove it correctly
3180 with regexps, so now it's removed automatically.
3181
31822002/04/19 : 1.1.9
3183 - don't use snprintf()'s return value as an end of message since it may
3184 be larger. This caused bus errors and segfaults in internal libc's
3185 getenv() during localtime() in send_log().
3186 - removed dead insecure send_syslog() function and all references to it.
3187 - fixed warnings on Solaris due to buggy implementation of isXXXX().
3188
31892002/04/18 : 1.1.8
3190 - option "dontlognull"
3191 - fixed "double space" bug in config parser
3192 - fixed an uninitialized server field in case of dispatch
3193 with no existing server which could cause a segfault during
3194 logging.
3195 - the pid logged was always the father's, which was wrong for daemons.
3196 - fixed wrong level "LOG_INFO" for message "proxy started".
3197
31982002/04/13 :
3199 - http logging is now complete :
3200 - ip:port, date, proxy, server
3201 - req_time, conn_time, hdr_time, tot_time
3202 - status, size, request
3203 - source address
3204
32052002/04/12 : 1.1.7
3206 - added option forwardfor
3207 - added reqirep, reqidel, reqiallow, reqideny, rspirep, rspidel
3208 - added "log global" in "listen" section.
3209
32102002/04/09 :
3211 - added a new "global" section :
3212 - logs
3213 - debug, quiet, daemon modes
3214 - uid, gid, chroot, nbproc, maxconn
3215
32162002/04/08 : 1.1.6
3217 - regex are now chained and not limited anymore.
3218 - unavailable server now returns HTTP/502.
3219 - increased per-line args limit to 40
3220 - added reqallow/reqdeny to block some request on matches
3221 - added HTTP 400/403 responses
3222
32232002/04/03 : 1.1.5
3224 - connection logging displayed incorrect source address.
3225 - added proxy start/stop and server up/down log events.
3226 - replaced log message short buffers with larger trash.
3227 - enlarged buffer to 8 kB and replace buffer to 4 kB.
3228
32292002/03/25 : 1.1.4
3230 - made rise/fall/interval time configurable
3231
32322002/03/22 : 1.1.3
3233 - fixed a bug : cr_expire and cw_expire were inverted in CL_STSHUT[WR]
3234 which could lead to loops.
3235
32362002/03/21 : 1.1.2
3237 - fixed a bug in buffer management where we could have a loop
3238 between event_read() and process_{cli|srv} if R==BUFSIZE-MAXREWRITE.
3239 => implemented an adjustable buffer limit.
3240 - fixed a bug : expiration of tasks in wait queue timeout is used again,
3241 and running tasks are skipped.
3242 - added some debug lines for accept events.
3243 - send warnings for servers up/down.
3244
32452002/03/12 : 1.1.1
3246 - fixed a bug in total failure handling
3247 - fixed a bug in timestamp comparison within same second (tv_cmp_ms)
3248
32492002/03/10 : 1.1.0
3250 - fixed a few timeout bugs
3251 - rearranged the task scheduler subsystem to improve performance,
3252 add new tasks, and make it easier to later port to librt ;
3253 - allow multiple accept() for one select() wake up ;
3254 - implemented internal load balancing with basic health-check ;
3255 - cookie insertion and header add/replace/delete, with better strings
3256 support.
3257
32582002/03/08
3259 - reworked buffer handling to fix a few rewrite bugs, and
3260 improve overall performance.
3261 - implement the "purge" option to delete server cookies in direct mode.
3262
32632002/03/07
3264 - fixed some error cases where the maxfd was not decreased.
3265
32662002/02/26
3267 - now supports transparent proxying, at least on linux 2.4.
