| - 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 |
| |
| 2007/01/22 : 1.3.6.1 |
| - change in the header chaining broke cookies and authentication |
| |
| 2007/01/22 : 1.3.6 |
| - 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 |
| - imported lots of docs |
| |
| 2007/01/07 : 1.3.5 |
| - stats: swap color sets for active and backup servers |
| - try to guess server check port when unset |
| - added complete support and doc for TCP Splicing |
| - replace the wait-queue linked list with an rbtree. |
| - a few bugfixes and cleanups |
| |
| 2007/01/02 : 1.3.4 |
| - 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 |
| |
| 2006/10/15 : 1.3.3 |
| - 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 |
| |
| 2006/09/03 : 1.3.2 |
| - started the changes towards I/O completion callbacks. stream_sock* have |
| replaced event_*. |
| - added the new "reqtarpit" and "reqitarpit" protection features |
| |
| 2006/07/09 : 1.3.1 (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. |
| |
| 2006/06/29 : 1.3.0 |
| - exploded the whole file into multiple .c and .h. No functionnal |
| difference is expected at all. |
| - fixed a bug by which neither stats nor error messages could be returned if |
| 'clitimeout' was missing. |
| |
| 2006/05/21 : 1.2.14 |
| - 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. |
| |
| 2006/05/14 : 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. |
| |
| 2006/05/13 : 1.2.13 |
| - '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. |
| |
| 2006/04/15 : 1.2.12 |
| Very few changes preparing for more important changes to support per-server |
| session limitations and queueing : |
| - ignore leading empty lines in HTTP requests as suggested by RFC2616. |
| - added the 'weight' parameter to the servers, limited to 1..256. It applies |
| to roundrobin and source hash. |
| - the optional '-s' option could clobber '-st' and '-sf' if compiled in. |
| |
| 2006/03/30 : 1.2.11.1 |
| - under some conditions, it might have been possible that when the |
| last dead server became available, it would not have been used |
| till another one would have changed state. Could not be reproduced |
| at all, however seems possible from the code. |
| |
| 2006/03/25 : 1.2.11 |
| - added the '-db' command-line option to disable backgrounding. |
| - added the -sf/-st command-line arguments which are used to specify |
| a list of pids to send a FINISH or TERMINATE signal upon startup. |
| They will also be asked to release their port if a bind fails. |
| - reworked the startup mechanism to allow the sending of a signal to a list |
| of old pids if a socket cannot be bound, with a retry for a limited amount |
| of time (1 second by default). |
| - added the ability to enforce limits on memory usage. |
| - added the 'source' load-balancing algorithm which uses the source IP(v4|v6) |
| - re-architectured the server round-robin mechanism to ease integration of |
| other algorithms. It now relies on the number of active and backup servers. |
| - added a counter for the number of active and backup servers, and report |
| these numbers upon SIGHUP or state change. |
| |
| 2006/03/23 : 1.2.10.1 |
| - while fixing the backup server round-robin "feature", a new bug was |
| introduced which could miss some backup servers. |
| - the displayed proxy name was wrong when dumping upon SIGHUP. |
| |
| 2006/03/19 : 1.2.10 |
| - assert.h is needed when DEBUG is defined. |
| - ENORMOUS long standing bug affecting the epoll polling system : |
| event_data is a union, not a structure ! |
| - Make fd management more robust and easier to debug. Also some |
| micro-optimisations. |
| - Limit the number of consecutive accept() in multi-process mode. |
| This produces a more evenly distributed load across the processes and |
| slightly improves performance by reducing bottlenecks. |
| - Make health-checks be more regular, and faster to retry after a timeout. |
| - Fixed some messages to ease parsing of alerts. |
| - provided a patch to enable epoll on RHEL3 kernels. |
| - Separated OpenBSD build from the main Makefile into a new one. |
| |
| 2006/03/15 : 1.2.9 |
| - haproxy could not be stopped after being paused, it had to be woken up |
| first. This has been fixed. |
| - the 'ulimit-n' parameter is now optional and by default computed from |
| maxconn + the number of listeners + the number of health-checks. |
| - it is now possible to specify a maximum number of connections at build |
| time with the SYSTEM_MAXCONN define. The value set in the configuration |
| file will then be limited to this value, and only the command-line '-n' |
| option will be able to bypass it. It will prevent against accidental |
| high memory usage on small systems. |
| - RFC2616 expects that any HTTP agent accepts multi-line headers. Earlier |
| versions did not detect a line beginning with a space as the continuation |
| of previous header. It is now correct. |
| - health checks sent to servers configured with identical intervals were |
| sent in perfect synchronisation because the initial time was the same |
| for all. This could induce high load peaks when fragile servers were |
| hosting tens of instances for the same application. Now the load is |
| spread evenly across the smallest interval amongst a listener. |
| - a new 'forceclose' option was added to make the proxy close the outgoing |
| channel to the server once it has sent all its headers and the server |
| starts responding. This helps some servers which don't close upon the |
| 'Connection: close' header. It implies 'option httpclose'. |
| - 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. |
| - 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. |
| - 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. |
| - the 'daemon' mode implies 'quiet' and disables 'verbose' because file |
| descriptors are closed. |
| |
| 2006/01/29 : 1.2.8 |
| - fixed a nasty bug affecting poll/epoll which could return unmodified data |
| from the server to the client, and sometimes lead to memory corruption |
| crashing the process. |
| - added the new pause/play mechanism with SIGTTOU/SIGTTIN for hot-reconf. |
| |
| 2005/12/18 : 1.2.7.1 |
| - the "retries" option was ignored because connect() could not return an |
| error if the connection failed before the timeout. |
| - TCP health-checks could not detect a connection refused in poll/epoll |
| mode. |
| |
| 2005/11/13 : 1.2.7 |
| - 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. |
| - delayed the quiet mode during startup so that most of the startup alerts can |
| 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. |
| - added "static-pcre" to the list of supported regex options in the Makefile. |
| |
| 2005/10/09 : 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. |
| |
| 2005/08/07 : 1.2.6 |
| - clean-up patch from Alexander Lazic fixes build on Debian 3.1 (socklen_t). |
| |
| 2005/07/06 : 1.2.6-pre5 (1.1.32) |
| - added the number of active sessions (proxy/process) in the logs |
| |
| 2005/07/06 : 1.2.6-pre4 (1.1.32-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. |
| |
| 2005/07/05 : 1.2.6-pre3 (1.1.32-pre3) |
| - 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). |
| |
| 2005/07/05 : 1.2.6-pre2 (1.1.32-pre2) |
| - 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. |
| |
| 2005/07/05 : 1.2.6-pre1 (1.1.32-pre1) |
| - 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. |
| |
| 2005/06/21 : 1.2.5.2 |
| - fixed build on PPC where chars are unsigned by default |
| |
| 2005/05/02 : 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. |
| |
| 2005/04/30 : 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 |
| |
| 2005/04/26 : 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 |
| |
| 2005/04/25 : 1.2.5-pre3 |
| - experimental epoll() support (use temporary '-e' argument) |
| |
| 2005/04/24 : 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 |
| |
| 2005/02/17 : 1.2.5-pre1 |
| - fixed a few errors in the documentation |
| |
| 2005/02/13 |
| - do not pre-initialize unused file-descriptors before select() anymore. |
| |
| 2005/01/22 : 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. |
| |
| 2005/01/22 : 1.2.3 (1.1.30) |
| - add an architecture guide to the documentation |
| - released without any changes |
| |
| 2004/12/26 : 1.2.3-pre1 (1.1.30-pre1) |
| - 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. |
| |
| 2004/10/18 : 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. |
| |
| 2004/08/10 : (1.1.29-pre2) |
| - 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() |
| |
| 2004/06/06 : 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> |
| |
| 2004/06/05 : |
| - added the "logasap" option which produces a log without waiting for the data |
| to be transferred from the server to the client. |
| - added the "httpclose" option which removes any "connection:" header and adds |
| "Connection: close" in both direction. |
| - added the 'checkcache' option which blocks cacheable responses containing |
| dangerous headers, such as 'set-cookie'. |
| - added 'rspdeny' and 'rspideny' to block certain responses to avoid sensible |
| information leak from servers. |
| |
| 2004/04/18 : |
| - send an EMERG log when no server is available for a given proxy |
| - added the '-c' command line option to syntactically check the |
| configuration file without starting the service. |
| |
| 2003/11/09 : 1.2.0 |
| - the same as 1.1.27 + IPv6 support on the client side |
| |
| 2003/10/27 : 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. |
| |
| 2003/10/22 : 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. |
| |
| 2003/10/15 : 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. |
| |
| 2003/09/21 : 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. |
| |
| 2003/09/19 : 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 |
| |
| 2003/09/10 : 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. |
| |
| 2003/05/06 : 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. |
| |
| 2003/04/21 : 1.1.20 |
| - fixed two problems with time-outs, one where a server would be logged as |
| timed out during transfer that take longer to complete than the fixed |
| time-out, and one where clients were logged as timed-out during the data |
| phase because they didn't have anything to send. This sometimes caused |
| slow client connections to close too early while in fact there was no |
| problem. The proper fix would be to have a per-fd time-out with |
| conditions depending on the state of the HTTP FSM. |
| |
| 2003/04/16 : 1.1.19 |
| - 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(). |
| |
| 2003/04/02 : 1.1.18 |
| - Haproxy can be compiled with PCRE regex instead of libc regex, by setting |
| REGEX=pcre on the make command line. |
| - HTTP health-checks now use "OPTIONS *" instead of "OPTIONS /". |
| - when explicit source address binding is required, it is now also used for |
| health-checks. |
| - added 'reqpass' and 'reqipass' to allow certain headers but not the request |
| itself. |
| - factored several strings to reduce binary size by about 2 kB. |
| - replaced setreuid() and setregid() with more standard setuid() and setgid(). |
| - added 4 status flags to the log line indicating who ended the connection |
| first, the sessions state, the validity of the cookie, and action taken on |
| the set-cookie header. |
| |
| 2002/10/18 : 1.1.17 |
| - 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. |
| |
| 2002/09/01 : 1.1.16 |
| - implement HTTP health checks when option "httpchk" is specified. |
| |
| 2002/08/07 : 1.1.15 |
| - replaced setpgid()/setpgrp() with setsid() for better portability, because |
| setpgrp() doesn't have the same meaning under Solaris, Linux, and OpenBSD. |
| |
| 2002/07/20 : 1.1.14 |
| - added "postonly" cookie mode |

| 2002/07/15 : 1.1.13 |
| - tv_diff used inverted parameters which led to negative times ! |
| |
| 2002/07/13 : 1.1.12 |
| - 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 |
| |
| 2002/07/04 : |
| - automatically close fd's 0,1 and 2 when going daemon ; setpgrp() after |
| setpgid() |
| |
| 2002/06/04 : 1.1.11 |
| - 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 RFC2965. |
| - 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. |
| |
| 2002/05/10 : 1.1.10 |
| - 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. |
| |
| 2002/04/19 : 1.1.9 |
| - don't use snprintf()'s return value as an end of message since it may |
| be larger. This caused bus errors and segfaults in internal libc's |
| getenv() during localtime() in send_log(). |
| - removed dead insecure send_syslog() function and all references to it. |
| - fixed warnings on Solaris due to buggy implementation of isXXXX(). |
| |
| 2002/04/18 : 1.1.8 |
| - 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". |
| |
| 2002/04/13 : |
| - http logging is now complete : |
| - ip:port, date, proxy, server |
| - req_time, conn_time, hdr_time, tot_time |
| - status, size, request |
| - source address |
| |
| 2002/04/12 : 1.1.7 |
| - added option forwardfor |
| - added reqirep, reqidel, reqiallow, reqideny, rspirep, rspidel |
| - added "log global" in "listen" section. |
| |
| 2002/04/09 : |
| - added a new "global" section : |
| - logs |
| - debug, quiet, daemon modes |
| - uid, gid, chroot, nbproc, maxconn |
| |
| 2002/04/08 : 1.1.6 |
| - 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 |
| |
| 2002/04/03 : 1.1.5 |
| - 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. |
| |
| 2002/03/25 : 1.1.4 |
| - made rise/fall/interval time configurable |
| |
| 2002/03/22 : 1.1.3 |
| - fixed a bug : cr_expire and cw_expire were inverted in CL_STSHUT[WR] |
| which could lead to loops. |
| |
| 2002/03/21 : 1.1.2 |
| - 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. |
| |
| 2002/03/12 : 1.1.1 |
| - fixed a bug in total failure handling |
| - fixed a bug in timestamp comparison within same second (tv_cmp_ms) |
| |
| 2002/03/10 : 1.1.0 |
| - 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. |
| |
| 2002/03/08 |
| - reworked buffer handling to fix a few rewrite bugs, and |
| improve overall performance. |
| - implement the "purge" option to delete server cookies in direct mode. |
| |
| 2002/03/07 |
| - fixed some error cases where the maxfd was not decreased. |
| |
| 2002/02/26 |
| - now supports transparent proxying, at least on linux 2.4. |
| |
| 2002/02/12 |
| - 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(). |
| |
| 2001/12/30 : release of version 1.0.2 : fixed a bug in header processing |
| 2001/12/19 : release of version 1.0.1 : no MSG_NOSIGNAL on solaris |
| 2001/12/16 : release of version 1.0.0. |
| 2001/12/16 : added syslog capability for each accepted connection. |
| 2001/11/19 : corrected premature end of files and occasional SIGPIPE. |
| 2001/10/31 : added health-check type servers (mode health) which replies OK then closes. |
| 2001/10/30 : added the ability to support standard TCP proxies and HTTP proxies |
| with or without cookies (use keyword http for this). |
| 2001/09/01 : added client/server header replacing with regexps. |
| eg: |
| cliexp ^(Host:\ [^:]*).* Host:\ \1:80 |
| srvexp ^Server:\ .* Server:\ Apache |
| 2000/11/29 : first fully working release with complete FSMs and timeouts. |
