The implementation has to deal with - phantom events (for fds which have been deleted/closed), similar - to the Linux RT signals code. Like the RT code, it maintains a - bitmask of active fds. After a successful call to kevent(), the - code will compress/overwrite dead events. The other annoyance is - that the handler must track the event filter for each fd, even - though you cannot support both read and write filters for the same - fd in one kqueue. The handler maintains a separate bitmask for fd - filters (1 == EVFILT_IN, 0 == EVFILT_OUT). - (adam) - -- server side includes - - added native server-side includes based on the docs from apache: - http://httpd.apache.org/docs/mod/mod_include.html - - not supported are: - - exec - - nested virtual - - config.errmsg - - echo.encoding - -24.07.2004 -- fdevents - - added a bitset to figure out if we received a event for an unregistered fd - in rt-signal (adam) - -- kqueue - - added kqueue support (Matt Levine) - -13.07.2004 08:58 -- configfile - - parse keys correctly that contain a digit (Geoff Adams) - -- fcgi - - fixed large post uploads (Geoff Adams) - fixed uri if docroot is set (Geoff Adams) - -03.07.2004 22:50 - 1.2.3 -- index-files - - rewrite uri.path to the index-file instead of keeping it at .../ - this fixes index-file handling in FastCGI/CGI docroot is used - -- close-on-exec - - enable close-on-exec handling to simplify FD handling in CGI code - -- cgi - - keep error-log-fd open to catch the error handling for execve() - - report error if cgi-exec file doesn't exist - -- proxy - - pass page-content on error to the user (E.R.) - code cleanup (E.R.) - -- ssi - - first skeleton of a plugin for ServerSideIncludes - -- security - - limit the headerlength again to 64k max - -03.07.2004 14:23 -- configure - - fixed compile-check for libpcre if pcre-config doesn't point to /usr/lib - -02.07.2004 18:17 -- buffers - - always allocate a multiply of 64bytes. this should reduce the number of - realloc()s and still doesn't has a too high overhead. - -02.07.2004 11:07 -- fds - - connect stdin, stdout and stderr to /dev/null instead of just closing it - use dup2() instead of dup() - -- accesslog - - if accesslog.filename starts with a | spawn a process which will get data - in one chunk once in a while - -01.07.2004 11:00 -- sample config - - added text/css and text/javascript mimetypes - -28.06.2004 12:18 -- proxy module - - added a proxy module (based on the fastcgi module) and added some - documentation - -25.06.2004 21:41 -- last-modified handling - - replaced %Z by GMT. otherwise the last-modified check will most often fail. - -24.06.2004 20:20 -- relax http-parser - - don't reply 400 in case of an empty header-field, just ignore it - -23.06.2004 22:10 -- file-cache - - don't cache mmap() for files larger than 64k as we run out of RAM otherwise - too fast (check with some 200mb files) - -- 64bit fixes - - fixed buffer_equal on sparc64 - -15.06.2004 19:09 - 1.2.2 -- mmap cache - - fixed mmap-caching in network_write.c and network_writev.c after a direct - hint by E.Rodichev - -- sendfile + linux - - check at config-time if sendfile() works on Linux - -11.06.2004 15:09 -- fcgi + unix sockets - - added support for unix domain sockets (spawn-fcgi 1.2.0 required) - -10.06.2004 11:49 -- configure - - use pcre-config to determine the position of the pcre headers - -05.06.2004 22:06 -- filehandle-cache - - remove mmap-segment if filecache gets invalidated - -30.05.2004 14:13 - lighttpd 1.2.1 -- response headers - - request headers that appear twice are grouped together like expected by - the CGI spec (concat with a ", ") - response headers behaved the same way but are not grouped anymore.

Basicly it was a cleanup of workflow of the creation of the - response-header. All modules can use a clean interface for this purpose - now. This is espacially usefull for all modules which have to pass some - HTTP-headers to the client. - -29.11.2003 22:22 -- modules - - finally moved the modules to shared libraries and cleaned up some code - path to become more readable. - - So far we have: - - mod_rewrite - mod_redirect - mod_access - mod_auth - mod_cache - mod_chat - mod_status - mod_maps - -28.11.2003 18:16 -- redirects - - as lighttpd supports url-rewriting redirection was a few lines of new code. - - redirect ^/wishlist/(.+) http://jan.kneschke.de/wishlist/$1 - - rewrite ^/wishlist/(.+) /new/wishlist/$1 - -28.11.2003 17:00 -- signal stuff - - setitimer is used to send a event every second to call time() only once a - second. another system call which has been remove from the main-loop. - - sending HUP to lighttpd will close and re-open the logfiles. this is used - for cycling logfiles. - -#! /bin/sh - -### -# -# a simple logfile rotator for lighttpd -# - -DATE=`date +"%Y%m%d-%H%M"` -LPID=`pidof lighttpd` -mv access.log access.log.${DATE} -kill -HUP ${LPID} -gzip access.log.${DATE} - -27.11.2003 01:07 -- native win32 port - - a first attempt for a native win32 has been done.

At the end this will just be a prove of concept. - -26.11.2003 01:17 -- access denied - - added a access-deny filter to block specific urls like - - access-deny ~ - access-deny .inc - -17.11.2003 01:06 -- bug fixing - - a fstat() on a opened fd which has changed reports wrong the file-info. - Using stat() again helps to solve this problem. - - the sig-io version doesn't suffer from this problem. - - the etags are now used for verifing file-cache-entries. - -- chat - - enabled the internal login mechanism again - - added support transfering session-infos over MySQL. - -15.11.2003 00:19 -- optimizing - - added a buffer_equal_reverse function which is optimized version of strcmp - which is going backwards as pathnames are often the same for in the first - bytes. - - wrote a one-pass parser for the request-header. The combination of - strstr(..., "\r\n") to seperate lines and strchr(..., ':') to seperate - keys from values more or less touched every byte twice. - - we are still at 18.000 req/s for 4kb keep-alive requests even with etags - and handling all header fields. - -14.11.2003 17:26 -- fcgi - - Content-Type wasn't passed correctly to the FastCGI app. HTTP_CONTENT_TYPE - was sent instead. - -- cache - - provided access to the Session-ID - -- error-log - - the timestamp is now written in a human readable form - -22.10.2003 00:06 -- fcgi, cgi - - added a special set of array-functions which are optimised for the "insert - only once" case. - - this provides access to the headers which are now forwarded to the external - interfaces. Before this change only a limited set of request-headers were - forwarded. - -21.10.2003 11:58 -- modules - - added a new module-hook after the basic-init of the module for handling - config-settings and prepare the overall operartion (like building - db-connections, compiling regexes, ...) - -- cache - - use turckmm-cache 2.4.3 to get some numbers for the php-latency: - - /usr/sbin/ab -n 10000 -c 10 http://alba.home.kneschke.de:1025/index.php - - handling the cache-decision and the cache-hit in php: - - cache-miss: 100% (-> $version = 0) - - plain : 108.13 req/s - turckmm-cache: 218.39 req/s - - cache-hit: 100% (-> $version = 1) - - plain : 164.45 req/s - turckmm-cache: 653.98 req/s - - handling the cache-decision and the cache-hit in the server: - - cache-hit: 100%, but using index.cml - - cml: 4918.84 req/s (no keep-alive) - cml: 6901.31 req/s (keep-alive) - - cache-miss: 100%, but using index.cml - - plain : 108.39 req/s - turckmm-cache: 217.84 req/s - - Conclusion: - - there is no loss in the cache-miss case through the cml-handling - - the cache-hit case can be improved dramaticly with lighttpd-cache - - turckmm-cache improves the cache-miss case alot - -20.10.2003 00:40 -- cache - - the first 'real-life' test showed dramatic improvements in the req/s - handling. - - The basic idea was to move the decision if a php-page can be taken from - the cache from the php-code to the webserver. - - See here why this is a good thing: - - the quite common code which works for http://jan.kneschke.de/ is using - templates and is quite static, but depends on 4 external files (the - menu-structure, the template, the current content, the class-file). - - the index-file is always: - - include_once "jk.inc"; - - $v = new view(); - print $v->get(array(array ("file" => "content.html"))); - - It is more or less the same for all pages. - - This basic setup can deliver 100 requests/s. - - The next step has: - - application bases caching - - as we know that each pages depends on those 4 files, you can check if they - have been modified since the last request and deliver the content from the - cache otherwise. - - this increased the throughput to 150 req/s. (cache-hit ratio 100%) - - The next logic step is to move the decision-making process out of the PHP - code as PHP is to slow for the cache-hit path: - - a CML (Cache-Markup-Language) has been written which describes the whole - decision process which has been written in PHP-code before: - - -output.content-type text/html - -output.include _cache.html - -trigger.handler index.php - -trigger.if file.mtime("../lib/php/menu.csv") > file.mtime("_cache.html") -trigger.if file.mtime("templates/jk.tmpl") > file.mtime("_cache.html") -trigger.if file.mtime("content.html") > file.mtime("_cache.html") - - if one of the 'trigger.if' statements is true the 'trigger.handler' is - called to generate the pages. - - if none of the them is trigger the files from 'output.include' are sent to - the browser with content-type specified in the first line: - - The result was very 'promissing': - - 5900 req/s with keep-alive - 3800 req/s without keep-alive - - (both for a cache-hit ratio of 100%) - - for keep-alive this is factor <b>59</b> against the plain un-cached - version and still <b>39</b> againt the php-cache-version which is doing - exactly the same. - - Time for party. :) - -19.10.2003 - 18:55 -- cache - - the handling of functions has been improved. they are now 'plugable'. just - the dlopen() stuff is missing. - - a new datatype has been added: the string - - this makes it possible to evaluate something like: - -trigger.if unix.time.now() - file.mtime("head.html") > 30 -trigger.if mysql.query("SELECT count(*) " + \ - " FROM structure AS struc, session AS sess " + \ - " WHERE struct.user = sess.user" + \ - " AND sess.id = \"" + mysql.escape("ab\"c") + "\"") - - you see: - - string operations (concat) - - handing of escape-sequences - - functions - - comparisions - -18.10.2003 - 13:39 -- cvs - - imported everything into the cvs server which makes the whole revision - handler a lot easier. The CVS server was up all the time but not used. - Importing required 5 minutes of work which included merge the freebsd and - the linux tree. - -- compilers + platforms - - on a regular various compilers and platform are check to compile with with - the current code base: - - platform | os | compiler | state - ---------+---------------------+--------------+--------- - ia32 | Linux 2.4.22 | gcc 2.95.3 | ok - ia32 | FreeBSD 5.1-CURRENT | gcc 3.3.1 | ok - mips64 | IRIX 6.5 | gcc 3.2.2 | ok - misp64 | IRIX 6.5 | MIPSpro 7.41 | ok - - the mipspro compiler revealed some warning which resulted in a nice - code-cleanup that made the code more readable. - -18.10.2003 - 03:00 -- e-tags and friends - - in preparation for the php-conference at the begin of november in - frankfurt/main the server has the support some more caching/proxy tags - like: - - E-Tag (14.19) [done] - - If-Match (14.24) - - If-None-Match (14.26) [done] - - If-Range (14.27) - - Section (13.3.3) binds them together. [RFC 2616] - - using lxr.kde.org and lxr.mozilla.org revealed that - - konqui only uses if-none-match - - mozilla uses if-none-match and if-range - - it looks like it isn't that easy to trigger the if-range case. - - As ulf suggested the etag is a hash of file-size, inode-number and mtime. - -- fd-caching - - ulf just phoned me ask proposed the free the cache more agressivly in case - of fd-shortage. increasing the the fd-limit is the better idea. :) - -17.10.2003 12:45 -- chat - - finished the mysql-support for storing the sessions - -12.10.2003 20:56 -- valgrind - - used valgrind again to verify that the code a free of mem-leaks and found - a 'leak generator' in the chunk-api. - - the last few leaks were just some missing free()'s at the end of the - program run which would have been freed anyway. - - at the end valgrind couldn't find any missing free()'s. - -11.10.2003 12:09 -- FastCGI - - reduced the number of system calls for FastCGI to WebServer to 2 calls per - fd-event.

Works fine now. - -30.04.2003 15:25 -- bug-fixing day - - While testing the FastCGI interface with the MSIE Björn Schotte discovered - that sometimes the output repeats itself from the start in an endless loop. - This bug has been fixed. - - The read-write-fallback for ancient systems seeked the wrong FDs. - - The FastCGI handler is now separting the HTTP-Header from the - response-body what results in a cleaner interface. The "header too long - for caching" message is gone now. - -28.04.2003 18:18 -- chunked transfer-encoding - - The FastCGI part is now using Chunked-Transfer-Encoding if HTTP/1.1 is - used and no content-length is specified. - -27.04.2003 23:10 -- chunked transfer-encoding - added "Transfer-Encoding: chunked" which is currently used in the web-chat - for the endless stream. Perhaps it helps some browsers. - - The FastCGI interface will get a the chunked-support too, as it will - enable keep-alive even if no content-length is returned from the FastCGI - process. We know the size of the chunks and will report it to the browser. - -16.04.2003 12:02 -- gigE deatchmatch - - sascha compared the current lighttpd to his premium thttpd in his - gigabit-Ethernet-Network. - - <a -href="http://schumann.cx/gbit_deathmatch.txt">http://schumann.cx/gbit_deathmatch.txt</a> - - small comment: - lighttpd provides the same performance (req/s and thoughput), but uses more - CPU-Time. - -10.04.2003 17:22 -- works on IRIX - - Jörg Behrens provided me login to his SGI Origin and after fixing two small - typos it worked fine on IRIX. (#if define HAVE... was missing a 'd' and - getopt returns a 'int' and not a 'char') - - IPv6 support is currently disabled for IRIX a gethostbyname2() isn't - available. - -10.04.2003 15:56 -- another bug-fixing day - The upper limit of open connections was enforced and a caused a seg-fault. - The current limit is set to 4096 parallel connections. - - As sascha benchmarked lighttpd and his premium thttpd I tried to reproduce - his reported results and had to fix 2 flaws in the async-io handling of - httpd_load which was used for the testing. - - If sascha starts another benchmark session I'll put a link to it here. - -09.04.2003 00:08 -- bug-fixing time - Date: and Last-Modified: where sending a timezone != GMT what was invalid. - The timestamp itself was correct, just the timezone use the wrong - characters. - - the fcgi-code had an buffer-overflow for larger POST-Requests. - - The fcgi-code still has problems with POST-Request larger than 16kb as the - the write buffer is full. Currently we don't handle this case except from - reporting it in the error-log. - -02.04.2003 01:17 -- cgi is back - - The CGI Interface wasn't tested for a longer time. It don't really - survived the introduction of the config-file handling and the internal - changes that were part of it. - - A small test with - -#! /usr/bin/perl -print "Content-Type: text/html\r\n\r\n"; -print time()."\n"; -0; - - produced 219 req/s. - - Calling PHP via the CGI interface results in 100 req/s. Same script, same - parameters for 'ab' and same PHP result in 1400 req/s if we use the - FastCGI interface. - - <b>Don't forget</b>: these benchmarks only represent figures for scenarios which - are not very realistic. They are just usefull for comparisions of the - internals. We don't want to benchmark applications. - -01.04.2003 23:04 -- new benchmarks - - This time we wanted to see if we can get the fastcgi-Interface a little bit - faster. We use this small script for the testing the interface. - -<?php - -ob_start(/*"ob_gzhandler"*/); -print "12345<br />\n"; -header("Content-Length: ".ob_get_length()); -ob_end_flush(); - -?> - - It generate a small network load and is the best case for benchmarking the - overhead of the call to the fastcgi-php. - - Using the chunk-API instead auf tmp-files increase the req/s vom 1200req/s - to 1600 req/s and the IO-load went down as expected. Waiting for the - filesystem and creating 1200 files per second required some time. The - CGI-Interface is still using tempfiles. - -01.04.2003 19:28 (no april fools joke) -- added SSL support - I took -lssl and -lcrypto and added SSLv2/SSLv3/TLS support to lighttpd. - - After some reading I realisized that libcrypto contained some of my code. - They have a similar buffer-struct with similar functions and they use the - same MD5-code from the RFC. :) - - Adding basic SSL-support was quite esay: replacing all write/read-calls by - SSL_write/read, initializing the ssl-context the right way and telling - openssl where to get the data from (SSL_set_fd). It fits really well into - lighttpd. - -- sidenote - sooner or later the con->filename handler will vanish in favour of the - direct interface to the chunk-API which will simplifiy the design a little - bit. - -31.03.2003 20:50 -- added a web-chat module - 1400 lines of C-code are neccesary to add a web-chat to lighttpd. - - Features: - - bb-code for text-layouting - - auto-highlight for URLs and Email-adresses - - unlimited number of channels - - max. 32.000 users per channel - - fast as it is directly integrated into the web-server - - easy to install (as easy as lighttpd) - - IRC-like (/msg, /kick, /me, ...) - - works with MS IE, Mozilla, Konqueror, ... - - uses as little JavaScript as possible to stay compatible with all browsers - - flood-protection (2 Levels: ignore and kick) - - uses CSS for customized look-and-feel - -25.03.2003 00:36 -- finished the config-file support - now we have config-sections - - [fastcgi] - fastcgi .php 192.168.2.76 1025 - - The only this missing is -HUP handling to re-read the config. But that - will follow when I'm up again. - -20.03.2003 01:04 -- adding config-file support - the most boring part of the writing programs after writing documentation. - The format is quite simple and good enough for lighttpd. - -19.03.2003 03:05 -- more on sendfile support - added support for freebsd's version of sendfile(). - - Linux: - ssize_t sendfile(int out_fd, int in_fd, off_t *offset, size_t count); - - FreeBSD: - int sendfile(int fd, int s, off_t offset, size_t nbytes, - struct sf_hdtr *hdtr, off_t *sbytes, int flags); - - the first 2 params are swap, the next 2 are the same and the last 3 are - set to NULL or 0. - - Solaris 9 is providing a direct interface to the chunk-API with the - sendfilev() system call: - - ssize_t sendfilev(int fildes, - const struct sendfilevec *vec, int sfvcnt, size_t *xferred); - - recovering from a failure is a little bit more complex, but it should be - fast. I just need a system to test it. Anyone ? - -18.03.2003 17:32 -- in the news - what a surprise: lighttpd is announced in entwickler.com. - - <a href="http://www.entwickler.com/itr/news/psecom,id,9483,nodeid,82.html">http://www.entwickler.com/itr/news/psecom,id,9483,nodeid,82.html</a> - - this was not planned. - - -- implemented the chunked-API - rather writing the content of multi-range'd requests to a temp-file we - just register the parts in a chunk-queue. - - chunk 1 [mem] - part-header - chunk 2 [file] - source-file (offset, len) - chunk 3 [mem] - part-header - chunk 4 [file] - source-file (offset, len) - chunk 5 [mem] - part-footer - - If everything is prepared, the content-length is calculated and the - http-header is generated and prepended to the chunk-queue. - - the handle_write() function which handles the write-process just sends the - chunks to the network without only further modifications. - - the chunk-api even simplifies the - 'my-fastcgi-process-needs-some-time-to-create-the-response- - and-sends-the-data-in-chunks' case.

This will result in strange errors. - (its a PHP bug) - 2. DOCUMENT_ROOT has been added to the environment variables - 3. a small bug for sending larger output from a fastcgi client has been - fixed. - -11.03.2003 11:52 -- added two neccesary features - - redirect _dir_ to _dir_/ - - append index-file to _dir_/ if they exist - -11.03.2003 00:13 -- another target - after adding some headers lighttpd compiles without any warnings - under cygwin on Windows. - - A native windows port will take some time as I have to figure out the - changes on the winsock.h to the unix headers. - -10.03.2003 11:52 -- added Solaris 8 and 9 - lighttpd has been confirmed to compile and work on - - - linux - - FreeBSD, NetBSD - - Solaris 8, 9 - - Perhaps I can get lcc to compile it on windows. - -10.03.2003 01:30 -- another platform was confirmed - lighttpd works on NetBSD - -- another webserver benchmark - mathopd (http://www.mathopd.org/) - - Mathopd/1.4 --c 10 -4k : 6329.11 [#/sec] -4k (keep-alive) : 10235.41 [#/sec] -100k : 1168.50 [#/sec] -100k (keep-alive) : 268.82 [#/sec] (99% idle) --c 100 -4k : ---- (connections dropped) -4k (keep-alive) : ---- -100k : ---- -100k (keep-alive) : ---- - -Very good values for small files, but the rest ? - -10.03.2003 00:06 -- added more write-handlers - 1. sendfile (linux only) - 2. mmap + write - 3. read + write - - This means that lighttpd runs on some more systems.
