| 2 | * |
| 3 | * 2002/09/01 : 1.1.16 |
| 4 | * - implement HTTP health checks when option "httpchk" is specified. |
| 5 | * 2002/08/07 : 1.1.15 |
| 6 | * - replaced setpgid()/setpgrp() with setsid() for better portability, because |
| 7 | * setpgrp() doesn't have the same meaning under Solaris, Linux, and OpenBSD. |
| 8 | * 2002/07/20 : 1.1.14 |
| 9 | * - added "postonly" cookie mode |
| 10 | * 2002/07/15 : 1.1.13 |
| 11 | * - tv_diff used inverted parameters which led to negative times ! |
| 12 | * 2002/07/13 : 1.1.12 |
| 13 | * - fixed stats monitoring, and optimized some tv_* for most common cases. |
| 14 | * - replaced temporary 'newhdr' with 'trash' to reduce stack size |
| 15 | * - made HTTP errors more HTML-fiendly. |
| 16 | * - renamed strlcpy() to strlcpy2() because of a slightly difference between |
| 17 | * their behaviour (return value), to avoid confusion. |
| 18 | * - restricted HTTP messages to HTTP proxies only |
| 19 | * - added a 502 message when the connection has been refused by the server, |
| 20 | * to prevent clients from believing this is a zero-byte HTTP 0.9 reply. |
| 21 | * - changed 'Cache-control:' from 'no-cache="set-cookie"' to 'private' when |
| 22 | * inserting a cookie, because some caches (apache) don't understand it. |
| 23 | * - fixed processing of server headers when client is in SHUTR state |
| 24 | * 2002/07/04 : |
| 25 | * - automatically close fd's 0,1 and 2 when going daemon ; setpgrp() after |
| 26 | * setpgid() |
| 27 | * 2002/06/04 : 1.1.11 |
| 28 | * - fixed multi-cookie handling in client request to allow clean deletion |
| 29 | * in insert+indirect mode. Now, only the server cookie is deleted and not |
| 30 | * all the header. Should now be compliant to RFC2109. |
| 31 | * - added a "nocache" option to "cookie" to specify that we explicitly want |
| 32 | * to add a "cache-control" header when we add a cookie. |
| 33 | * It is also possible to add an "Expires: <old-date>" to keep compatibility |
| 34 | * with old/broken caches. |
| 35 | * 2002/05/10 : 1.1.10 |
| 36 | * - if a cookie is used in insert+indirect mode, it's desirable that the |
| 37 | * the servers don't see it. It was not possible to remove it correctly |
| 38 | * with regexps, so now it's removed automatically. |
| 39 | * 2002/04/19 : 1.1.9 |
| 40 | * - don't use snprintf()'s return value as an end of message since it may |
| 41 | * be larger. This caused bus errors and segfaults in internal libc's |
| 42 | * getenv() during localtime() in send_log(). |
| 43 | * - removed dead insecure send_syslog() function and all references to it. |
| 44 | * - fixed warnings on Solaris due to buggy implementation of isXXXX(). |
| 45 | * 2002/04/18 : 1.1.8 |
| 46 | * - option "dontlognull" |
| 47 | * - fixed "double space" bug in config parser |
| 48 | * - fixed an uninitialized server field in case of dispatch |
| 49 | * with no existing server which could cause a segfault during |
| 50 | * logging. |
| 51 | * - the pid logged was always the father's, which was wrong for daemons. |
| 52 | * - fixed wrong level "LOG_INFO" for message "proxy started". |
| 53 | * 2002/04/13 : |
| 54 | * - http logging is now complete : |
| 55 | * - ip:port, date, proxy, server |
| 56 | * - req_time, conn_time, hdr_time, tot_time |
| 57 | * - status, size, request |
| 58 | * - source address |
| 59 | * 2002/04/12 : 1.1.7 |
| 60 | * - added option forwardfor |
| 61 | * - added reqirep, reqidel, reqiallow, reqideny, rspirep, rspidel |
| 62 | * - added "log global" in "listen" section. |
| 63 | * 2002/04/09 : |
| 64 | * - added a new "global" section : |
| 65 | * - logs |
| 66 | * - debug, quiet, daemon modes |
| 67 | * - uid, gid, chroot, nbproc, maxconn |
| 68 | * 2002/04/08 : 1.1.6 |
| 69 | * - regex are now chained and not limited anymore. |
| 70 | * - unavailable server now returns HTTP/502. |
| 71 | * - increased per-line args limit to 40 |
| 72 | * - added reqallow/reqdeny to block some request on matches |
| 73 | * - added HTTP 400/403 responses |
| 74 | * 2002/04/03 : 1.1.5 |
| 75 | * - connection logging displayed incorrect source address. |
| 76 | * - added proxy start/stop and server up/down log events. |
| 77 | * - replaced log message short buffers with larger trash. |
| 78 | * - enlarged buffer to 8 kB and replace buffer to 4 kB. |
| 79 | * 2002/03/25 : 1.1.4 |
| 80 | * - made rise/fall/interval time configurable |
| 81 | * 2002/03/22 : 1.1.3 |
| 82 | * - fixed a bug : cr_expire and cw_expire were inverted in CL_STSHUT[WR] |
| 83 | * which could lead to loops. |
| 84 | * 2002/03/21 : 1.1.2 |
| 85 | * - fixed a bug in buffer management where we could have a loop |
| 86 | * between event_read() and process_{cli|srv} if R==BUFSIZE-MAXREWRITE. |
| 87 | * => implemented an adjustable buffer limit. |
| 88 | * - fixed a bug : expiration of tasks in wait queue timeout is used again, |
| 89 | * and running tasks are skipped. |
| 90 | * - added some debug lines for accept events. |
| 91 | * - send warnings for servers up/down. |
| 92 | * 2002/03/12 : 1.1.1 |
| 93 | * - fixed a bug in total failure handling |
| 94 | * - fixed a bug in timestamp comparison within same second (tv_cmp_ms) |
| 95 | * 2002/03/10 : 1.1.0 |
| 96 | * - fixed a few timeout bugs |
| 97 | * - rearranged the task scheduler subsystem to improve performance, |
| 98 | * add new tasks, and make it easier to later port to librt ; |
| 99 | * - allow multiple accept() for one select() wake up ; |
| 100 | * - implemented internal load balancing with basic health-check ; |
| 101 | * - cookie insertion and header add/replace/delete, with better strings |
| 102 | * support. |
| 103 | * 2002/03/08 |
| 104 | * - reworked buffer handling to fix a few rewrite bugs, and |
| 105 | * improve overall performance. |
| 106 | * - implement the "purge" option to delete server cookies in direct mode. |
| 107 | * 2002/03/07 |
| 108 | * - fixed some error cases where the maxfd was not decreased. |
| 109 | * 2002/02/26 |
| 110 | * - now supports transparent proxying, at least on linux 2.4. |
| 111 | * 2002/02/12 |
| 112 | * - soft stop works again (fixed select timeout computation). |
| 113 | * - it seems that TCP proxies sometimes cannot timeout. |
| 114 | * - added a "quiet" mode. |
| 115 | * - enforce file descriptor limitation on socket() and accept(). |

| 120 | * 2001/11/19 : corrected premature end of files and occasional SIGPIPE. |
| 121 | * 2001/10/31 : added health-check type servers (mode health) which replies OK then closes. |
| 122 | * 2001/10/30 : added the ability to support standard TCP proxies and HTTP proxies |
| 123 | * with or without cookies (use keyword http for this). |
| 124 | * 2001/09/01 : added client/server header replacing with regexps. |
| 125 | * eg: |
| 126 | * cliexp ^(Host:\ [^:]*).* Host:\ \1:80 |
| 127 | * srvexp ^Server:\ .* Server:\ Apache |
| 128 | * 2000/11/29 : first fully working release with complete FSMs and timeouts. |
