+- Makefile

+- combo patch
+
+  * Tinker with kqueue().  Add a reset method so that the kqueue file
+    descriptor can be re-enabled after a fork().  Emulate the devpoll driver
+    in that adds and deletes are sent to the notification mechanism im-
+    mediately, which should cut down on phantom events.  Use
+    ev->kq_results as a sliding window.
+  
+  * Change F_SETFD calls to use the preferred FD_CLOEXEC instead of 1.
+  
+  * Remove unnecessary fdevent fcntl handlers.  It appears that the only
+    driver that needs one is Linux RT signals.
+    
+  * Quiet compiler warning about unused parameter.
+    
+  * Set the close-on-exec flag for the /dev/poll and epoll_create() file
+    descriptors.
+      
+  * Return failure if /dev/poll could not be opened instead of logging
+    and continuing.
+	
+  * Detect EAGAIN after writev() failures.  FreeBSD sendfile() doesn't need
+    protection, as the man page says:
+	  
+     When using a socket marked for non-blocking I/O, sendfile() may send
+     fewer bytes than requested.  In this case, the number of bytes success-
+     fully written is returned in *sbytes (if specified), and the error
+     EAGAIN is returned.

+  kqueue: events == FDEVENT_IN -> events & FDEVENT_IN (adam)
+
+31.07.2004 22:07 - 1.2.4
+- fdevents
+
+  * Test at configure time for kqueue() and <sys/event.h>
+  * Remove various hard-coded constants from event handlers
+  * Move maxfds into the event structure, and out of the
+    fdevent_*_init handlers.  Event handlers can use the maxfds
+    member to size arrays.
+  * Various event structure renames to discourage clashes
+  * Remove extra (ignored) call to fdevent_event_next_fdndx() in
+    the main server loop.
+  * Wrestle with kqueue().  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

+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. They

+- array handling
+
+  how did that bug survive such a long time ? a wrong compare function was
+  used in one case, but not the other.
+
+15.05.2004 03:20
+- secure and fast downloads
+
+  added a module which allows secure and fast downloading of files:
+  1. the application (.php, ...) controls the access to the files
+  2. the webserver is handling the transfer (and check the app generated
+     tokens)
+     
+  the token is based on 
+  - a secret
+  - a timestamp
+  - the filename
+  this means even if the token is is distributed by the user it will get
+  invalid after a given timeout (default 60 seconds)
+  
+- errorfiles
+
+  check for errorfiles before using them
+     
+- code cleanup

+  applied cleanup fixes from adam
+
+14.05.2004 18:47
+- fdevent handling
+
+  added a more generic callback interface to the fdevent structures which

+  while
+  
+- cgi
+
+  fixed header parsing of the header is sent in chunks and the terminator is
+  sent in a single chunk

+25.04.2004 19.15
+- mem-leak
+
+  fixed mem-leak on broken HTTP-headers
+  
+- FastCGI
+
+  patches from E.Rodichev:
+  
+  1. CONTENT_LENGTH
+  "If no data are attached, then this metavariable is either NULL or not
+  defined".
+  
+  2. QUERY_STRING
+  If the Script-URI does not include a query component, the QUERY_STRING
+  metavariable MUST be defined as an empty string ("").
+  
+  3. Doubling of REMOTE_ADDR removed.
+  
+  patches from adam:
+  * fixed bug in the sizeof() patches from yesterday.
+  * some more *_long to *_off_t 
+
+24.04.2004 14:34
+- FastCGI
+

+24.04.2004 12:13
+- POST
+
+  fixed POST request handling
+  
+- chunk-encoding
+
+  the generated HEX strings where broken since the 1.1.8
+  (this effected all HTTP/1.1 requests without Content-Length like FastCGI-PHP)
+
+- code cleanup
+
+  patches from adam:
+  * malloc + memset -> calloc
+  * sizeof(int) -> sizeof(<variable>)
+  * assign fd_set instead of memcpy()
+  * init fd -> connection fd pointers to -1
+  
+16.04.2004 08:48 - 1.1.8
+- code cleanup
+  
+  don't reuse buffer > 64k (see settings.h)
+  
+  added server.max-request-size to limit the maximum request-body size 
+  (in kBytes)
+  
+  don't accept HTTP-request headers larger then 32kBytes (see settings.h)
+  
+  minor speed improvements in the request-parser
+  
+  More cleanup patches from adam:
+  
+  * change pre-ANSI C/valid C++ syntax for function declarations/definitions
+    from using () to (void).  Ex: int foo(); --> int foo(void);
+  * use static linkage as much as possible, to limit possible symbol
+    collisions
+  * whack more unneeded variables
+  * try and prevent any errno clobbering by storing the old errno value before
+    any subsequent system calls, and restoring before function exit.  
+  * change printf syntax for unsigned variables from %d to %u
+    
+15.04.2004 18:41
+- code cleanup
+
+  handle all int != size_t cases in fcgi.c correctly

+  handle both EINVAL cases of writev() before the can occur
+  
+  limit content-length to SSIZE_MAX 
+  disallow negative content-length
+  
+  the usage of ltostr() has been reduced to the minimum in favour of 
+  buffer_/append|copy)_(long|off_t)
+  
+  dropped ultostr() and ultohex() in favour of buffer_*
+
+15.04.2004 16:35
+- portablity 
+
+  more patches from adam:
+  
+  * remove warnings for unused parameters and variables
+  * remove warnings for mismatched pointer assignments
+  * change "gtime_r" to "gmtime_r"
+
+13.04.2004 20:48
+- test-cases 
+
+  made the 'make check' target self-contained
+  
+  In our case we have to call the targets in the following order:
+  
+  $ ./configure ...
+  $ make 
+  $ make install
+  $ make check
+  
+  because the path to the plugins is hardcoded in the binary itself
+  
+  using 
+  
+  $ ./configure --prefix=/tmp/lighttpd-1.1.x/
+  ...
+  
+  will help if you don't really want to install before testing.
+
+13.04.2004 00:05
+- portability 
+
+  adam sent another patchset:
+  
+  * Wrap PCRE-specific data member access with an #ifdef
+  * Add const to pointer using return value from dlerror()
+  * Explicitly initialize pointer in the lemon parser to 0,
+    in order to catch missing else { } clause
+  * Use a time_t rather than an int for gmtime() call.  On some
+    systems (including 32- and 64-bit SPARC) time_t is a long.
+
+12.04.2004 17:00 - 1.1.7
+- fastcgi

+- code cleanup
+
+  moved the config for the cgi-plugin from config.c to the plugin.
+  
+  moved some buffers which were only used by a one or two plugin from
+  the server-structure to the plugins
+  
+  keeping the plugins independent from the server-core is a 'good thing'
+
+10.04.2004 19:06
+- configfile parser
+
+  removed the leaks from the configfile parser
+
+09.04.2004 23:15 - 1.1.6
+- stricter http-parser
+
+  added line-folding although noone really seems to use it.
+
+09.04.2004 18:42
+- configfile parser
+
+  the hand-written configfile parser has been replaced by a LALR(1) one.
+  'lemon' from the sqlite guys has been used to generate the parser.
+
+- by-host, by-url, by-file, by ... 
+
+  $HTTP["url"] =~ "~$" {
+    access.deny = "all"
+  }
+  
+  $HTTP["host"] =~ "." {
+    simple-vhost.server-root    = "/home/weigon/wwwroot/servers/"
+    simple-vhost.default-host   = "grisu.home.kneschke.de"
+    simple-vhost.document-root  = "pages"
+  }
+ 
+  $HTTP["host"] == "incremental.home.kneschke.de" {
+    server.docroot              = "/hasdasd"
+  }
+  
+  at least the parser can handle it now. Currently there is no real support
+  for this context-based config-option. But the syntax and the parser are
+  done.
+  
+09.04.2004 10:58
+- ssl support
+
+  enable ssl support again
+  
+- mmap
+
+  enabled mmap+write again 
+  
+08.04.2004 12:34
+- stricter http-parser
+
+  based on a thread at 
+  
+  http://lists.w3.org/Archives/Public/ietf-http-wg/2004JanMar/0050.html
+  
+  the HTTP-parser has been adjusted to be more correct when it comes to 
+  request-header fieldnames
+  
+  the whitespace handling around the ':' has been relaxed as requested
+  
+07.04.2004 17:06
+- sigaction
+
+  use sigaction instead of signal if possible
+
+07.04.2004 13:55
+- accesslog
+
+  use localtime-timestamps in accesslogs if struct tm has a tm_gmtoff field
+
+07.04.2004 10:41 - 1.1.5
+- -D_REENTRANT
+
+  solaris + localtime_r() needs it
+
+07.04.2004 02:54
+- mod_auth + ldap
+
+  added a ldap backend to the auth plugin.
+
+06.04.2004 13:37
+- pidfile
+
+  fixed the permissions of the pidfile (Matthijs van der Klip)
+  
+- specfile
+
+  merge the RedHat and SuSE specfile with Matthijs
+  
+- 64bit file-offsets
+
+  moved the FILE_OFFSET_BITS settings from the config.h the Makefile to enable
+  64bit offsets the right way
+
+06.04.2004 12:32
+- mod_expire
+
+  added an apache compatible mod_expire which adds Expires: headers to the
+  request
+  
+  expire.url = ( "/buggy/" => "access 2 hours" )
+
+05.04.2004 22:34
+- solaris devpoll
+
+  forgot to provide the infrastructure to actually enable the devpoll event
+  handler. the same has been done for the freebsd-kqueue handler (which
+  doesn't work yet)
+  
+  fixed the devpoll support while testing it on a real solaris box
+
+05.04.2004 09:49
+- debian
+
+  added debian packaging support written by Vincent Wagelaar
+  
+- solaris
+
+  Another set of patches for Solaris from Adam
+  * Detect <sys/devpoll.h>
+  * Detect and include <sys/filio.h> for definition of FIONREAD
+  * Detect and link against the library exporting hstrerror
+  * Correct typo in SENDFILE_LIB
+  * Use__sun instead of __solaris__ for detecting operating system.
+    Please see http://predef.sourceforge.net/preos.html for more
+    detail
+  * Explicitly cast arguments to isalpha() and toupper() to unsigned
+    char.  The man page says that the functions support the range of
+    an unsigned char, and EOF.
+  * Include <limits.h> and define UIO_MAXIOV as IOV_MAX for Solaris.
+
+04.04.2004 18:05 - 1.1.4
+- pidfile
+
+  added pidfile writing after deamonizing
+
+04.04.2004 01:05
+- fdevent
+
+  added framework for freebsd_kqueue and solaris_devpoll
+  
+  the solaris_devpoll one might event work (untested)
+
+03.04.2004 16:41
+- network 
+
+  added framework for filebased chunks
+  - read-write + mmap-write
+  - linux-sendfile
+  - freebsd-sendfile
+  - solaris-sendfilev (untested)
+  
+  and memorybased chunks
+  - write
+  - writev
+  
+  made TCP_CORK a 'global' flag around the write_chunkqueue-calls
+  
+  the writev() support should improve the performance for all non-static
+  pages. 
+  
+  170 req/s against 158 req/s for the following script if writev() is used
+  instead of write()
+  
+  <?php
+  
+  for ($i = 0; $i < 1000; $i++) {
+      print $i."<br />\n";
+      flush();
+  }
+	  
+  ?>
+
+28.03.2004 13:42
+- cleanup
+
+  applied some cleanup patches submitted by Adam:
+  * variables modified in signal handlers should be sig_atomic_t
+  * assert statements should not have side effects
+  * STD{IN,OUT,ERR}_FILENO preferred instead of {0,1,2}
+  * dieing --> dying
+  * SEGFAULT calls abort directly, instead of derefencing a NULL pointer
+  
+- mod_accesslog
+
+  modified the accesslog format to be CLF compatible
+  set locale for LC_TIME to C
+  
+26.03.2004 16:13 
+- path info
+
+  enabled the pathinfo code again
+  
+
+25.03.2004 13:30 - 1.1.3
+- portability 
+
+  compiles fine now without any patches on IRIX
+  
+- hostname detection
+
+  reworked "get the hostname for HTTP/1.0 requests which don't specify a
+  Host: ..." to only query the name in this single case for the server side
+  of the connection
+  
+- errorlog handling
+
+  stderr is only used until the errorlog is init'ed
+  if no error-log is specified, syslog() is used
+  if cycling error-log fails, syslog() is used
+  
+- accesslog cycling
+
+  don't fall back to stdout anymore
+
+- event-handler
+
+  use poll() as the default event-handler again
+
+24.03.2004 01:37 - 1.1.2a
+- error messages
+
+  added some hints to the failing error-messages
+
+22.03.2004 01:58 - 1.1.2
+- configure
+
+  some protability changes to get the 'inline' working with the MIPS CC
+  
+21.03.2004 22:00
+- mod_rewrite, mod_redirect
+
+  reading the config for those two plugins was not working
+  
+- fdevents
+
+  changed the compile time setting for the event handling into a run-time
+  setting.
+  
+  server.event-handler = "select" # poll, linux-rtsig, linux-sysepoll
+  
+  added sys_epoll() for linux 2.6
+  
+  select       - all systems
+  poll         - Linux 2.1.23+, all XPG4-UNIX
+  sigio        - linux 2.4.0+ 
+  sysepoll     - linux 2.5.66+
+  
+           1000-4k-nok   1000-100k-nok
+  select       1776.99          296.52
+  poll          678.02          607.28
+  sigio        3754.46         1411.23
+  sysepoll     3817.67         1431.02
+
+21.03.2004 00:10
+- configure script
+
+  rewrote large parts of the lib/header detection of the configure script
+
+20.03.2004 01:39
+- fastcgi
+
+  as the docroot on external hosts might be different than the webserver
+  docroot it can now be specified in the config:
+  
+  fastcgi.server            = ( ".php" =>
+				( "grisu" => 
+				  ( 
+				    "host" => "192.168.2.41",
+				    "docroot" => "/home/jan/servers/",
+				    "port" => 1026
+				  )
+				)
+			      )
+			      
+  a huge internal cleanup in the config handling made the code more readable.
+  some more warnings and error checking should track most of the config
+  errors for the fastcgi plugin 
+
+19.03.2004 12:34
+- external patches
+
+  Matthijs van der Klip submitted three nice patches:
+  - turn off writing in mod_status if status.rrd-reports is set to disable
+  - fix for a debug message
+  - get the hostname for HTTP/1.0 requests which don't specify a Host: ...
+  - rc-script for RedHat
+  
+- documentation
+
+  added a documentation section about authentification
+  - doc/authentification.txt
+
+19.03.2004 05:11
+- optimizations
+
+  implemented special versions of 
+  - strcasecmp (array_strcasecmp)
+  - isdigit, isalpha, isalnum (light_*)
+  
+  added a faster check for a finished header
+  
+  after disabling all modules it is still possible to get 20 kreq/s.
+
+15.03.2004 19:45 - 1.1.1
+- localizer server
+
+  added the localizer-server module to the code 
+  
+- chunked-encoding
+
+  Apple's Safari or HTTP-Handler doesn't handle chunked-extensions defined by 
+  RFC 2616 correctly and doesn't ignore them. Disabled the chunked-extension
+  which were just used for debugging purposes.
+
+07.03.2004 12:20
+- optimization
+
+  moved the checks if a plugins support a given function from the dispatcher
+  (plugins_call) to plugins_call_init() to do the check only once.
+  
+  equalized the plugins functions to only two types:
+  SERVER_FUNC()
+  CONNECTION_FUNC()
+  
+  replaced all handwritten plugin_call-handlers with macros
+  
+  made all plugin-functions 'static'
+  
+  with all plugins loaded we are at 15kreq/s gain
+  without any plugin loaded at 16kreq/s
+  
+  before the change we were at 13kreq/s
+
+06.03.2004 21:13 
+- compilation fixes
+
+  fixed some warnings on FreeBSD and NetBSD by adding
+  #include <netinet/in.h> 
+  
+  ifdef'ed a pcre-entry in base.h
+  
+  remove #define _XOPEN_SOURCE from http_auth.c for IRIX
+  crypt() on Linux needs _XOPEN_SOURCE
+
+06.03.2004 19:18 - 1.1.0
+- authentification
+
+  added htpasswd and htdigest backends to work against user-files generated
+  by htpasswd and htdigest.
+  
+  for basic auth:
+  - plain
+  - htpasswd (crypt only)
+  - htdigest
+  
+  for digest auth:
+  - plain
+  - htdigest
+  
+06.03.2004 17:35
+- authentification
+
+  check the method in the authorization header againt the configured method 
+
+06.03.2004 14:54
+- hostname parsing
+
+  added a RFC-2396 conforming "Host:" parser
+  added 17 checks for the parser
+
+06.03.2004 10:25
+- configuration
+
+  added a warning for unknown configuration variables.
+  
+  dropped the 'specific-for.url' ideas for now as it is not known yet how to
+  implement it the right way
+  
+  renamed some config-variables to reflect there actual meaning
+  - server.host -> server.bind
+  - server.virtual-* -> simple-vhost.*
+  - server.userid -> server.username
+  - server.groupid -> server.groupname
+  - server.docroot -> server.document-root
+  
+
+05.03.2004 15:36
+- fastcgi
+
+  internals: moved all mod_fastcgi settings from the global struct to the
+    plugin itself
+
+- vhosting
+  
+  got a patch for enhanced virtualhosting from christian kruse -> mod_evhost
+  
+  moved the virtual hosting config (server.virtual-*) to it's own module
+  called mod_simple_vhost
+
+23.02.2004 10:06
+- configfile
+  
+  rearragned the config-file structure again to be able to add settings for
+  a given URL, Host, Filename, ... 
+    This change affects some config-options directly (access.deny,
+  url.rewrite, url.redirect, virtual-hosting, ...)
+  
+  added 'specific-for.url' for url specific config settings 
+  
+- digest auth
+
+  FIX: md5-sess type
+  
+  seperate the auth-backend stuff
+
+13.02.2004 22:23 - lighttpd 1.0.3
+- content-length + POST
+
+  FIX: If header and content didn't fit into one single packet the rest of
+       the content was not read correctly
+
+13.02.2004 01:07
+- content-length + POST
+
+  the check for content-length on a POST request vanished somehow in one of
+  the previous releases.
+
+- header search
+
+  FIX: the search for header fields was up to now case-sensitive. Now it is
+       like required by the standard case-in-sensitive.
+       
+- browser bugs
+  
+  w3m 0.2.5 adds an additional \r\n at the end of the POST requests which is
+  handled now
+ 
+10.02.2004 10:12
+- start script
+
+  took the suse rc-skeleton which states to be LSB compliant and modified it
+  for lighttpd needs
+  
+09.02.2004 11:48 
+- HEAD requests
+
+  FIX: HEAD requests for static files delived the content from the GET
+       request. (test case is added)
+
+08.02.2004 15:53 
+- directory listings
+  
+  FIX: the pathname has not encoded at all before it was transfered to the 
+       browser. a proper url and html-encoding has been added.
+  
+  added modification-time and filesize to the output 
+  
+  added a basic css for the virtual listings
+
+07.02.2004 22:15 - lighttpd 1.0.2
+- sample configfile
+
+  rearranged the config-file to have all the important options at the top
+  
+- docs
+
+  added a mod-rewrite options
+  
+- mod_accesslog
+
+  stdout is no longer used a default for the accesslog
+  
+- error-messages
+
+  the 404 is now reported in the error-log
+
+07.02.2004 17:30
+- configfile handling
+
+  if a key is used twice like
+  
+  url.rewrite = ( "url1" => "url") 
+  url.rewrite = ( "url2" => "url") 
+  
+  you get an error now. You have to write:
+  
+  url.rewrite = ( "url1" => "url", 
+                  "url2" => "url") 
+
+31.01.2004 12:22 - lighttpd 1.0.1
+- log cycling
+
+  added a sighup-handler to the plugin interface and fixed the log-cycling
+  for access-logs
+  
+- portability
+  
+  disabled the interval-time optimization on IRIX
+
+- documentation
+  
+  added a lot of new documentation to README
+
+31.01.2004 10:59
+- status module
+
+  added two new options rrd-dir and rrd-reports:
+  
+  rrd-reports = (boolean)  # enables RRD-reports
+  rrd-dir     = (string)   # path for the daily status-files
+  
+  fixed the "status-files in /"-bug this way
+  
+
+22.01.2004 13:38 - lighttpd 1.0.0
+- simple docroot
+
+  fixed handling of docroots if virtual-host is disabled
+
+27.12.2003 11:12
+- license handling
+
+  added the first interface to license handling.
+
+25.12.2003 23:48
+- protability
+
+  Verified again that the code compiles and runs cleanly on Linux, FreeBSD,
+  NetBSD and IRIX
+  
+  compiling with gcc and the option -pedantic works fine
+  compiling with mipspro cc works fine, too
+  
+- tests
+
+  added some more tests: 39 tests
+
+25.12.2003 16:01
+- protability
+
+  some compile fixes for FreeBSD have been applied and a new switch has been
+  added to choose between IPv4 and IPv6 on FreeBSD. 
+    (cmdline: -6, configfile: server.use-ipv6)
+
+- packaging
+  
+  cleaned up the specfile for building RPMs
+
+21.12.2003 01:00
+- authorization
+
+  brought basic and digest auth back to life. this module as the last one
+  which had to be updated after the config-file changes
+
+- test harness framework
+
+  add 3 tests for basic auth
+
+20.12.2003 22:10
+- compression
+
+  added gzip compression (gzip-header + deflate + crc)
+  
+- test harness framework
+
+  added a 22 tests to verify the correct behaviour of lighttpd
+
+- request parsing
+
+  GET http://www.yahoo.com/ HTTP/1.0
+  
+  is handled now as
+  
+  GET / HTTP/1.0
+
+- plugins
+
+  moved FastCGI and CGI handling into modules which can be loaded at run-time
+
+17.12.2003 13:18
+- compression
+
+  the directory structure is now build automaticly
+
+15.12.2003 01:00
+- compression 
+  
+  added a compression cache to the compression module (mod_compress)
+
+  Vary: Accept-Encoding is set now as it influences to delivered stream of
+  bytes. This is important for caches.
+
+10.12.2003 00:24
+- config files
+
+  a new config-file format is ready for the final release of lighttpd.
+  
+  it supports:
+  
+  server.docroot   = "string"
+  server.host      = integer
+  server.modules   = ( "string", "string" )
+  server.mimetypes = ( "key" => "value" )
+  server.complex   = ( "key" => ( "string", integer ), 
+                       "string", 
+		       integer )
+  
+  the syntax should look familar to all who worked with Perl or PHP.
+  
+  config-file handling has been seperated into a parser and a lexer. Both
+  are currently written by hand and will propably be rewritten into bison +
+  flex if time permits. But that would be a cosmetical change.
+
+05.12.2003 03:07
+- status-page
+
+  improved the status page to display
+  - the current connection-stati
+  - average throughput over 5 seconds 
+    (requests/s and output-bound traffic)
+
+  now you can see what is going on in the server
+  
+- access-log
+
+  the accesslog is now a module and can be disabled by just removing the
+  plugin from the list of loaded plugins
+
+04.12.2003 16:18
+- chroot-ing
+
+  how-to: using chroot
+  
+  - chroot to /home/www/
+  - docroot at /servers/<hostname>/pages/
+  - defaulthost www.example.org
+  
+  e.g. (external view)
+  /home/www/servers/www.example.org/pages/index.html
+  
+  (in chroot)
+  /servers/www.example.org/pages/index.html
+  
+  config:
+  
+  chroot  /home/www/
+  userid  wwwrun
+  groupid nogroup
+  
+  virtual-server-root /servers/
+  virtual-server-default-host www.example.org
+  virtual-server-docroot /pages/
+  
+  The FastCGI process is living outside this chroot definition as it is 
+  started seperatly.
+  
+01.12.2003 02:06
+- cleanup
+
+  in preparation for the first stable release some internals had to be
+  cleaned up. 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. For now mingw is the
+  base for the development as it provides a basic unix-like framework for
+  building native win32 applications.
+  
+  the most internal files have been ported and the over all progress is
+  going well. 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

+  
+- 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% (-&gt; $version = 0)
+  
+    plain        : 108.13 req/s
+    turckmm-cache: 218.39 req/s
+  
+    cache-hit: 100% (-&gt; $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

+- 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. (ioctl() + read())
+  
+  this has no direct effect of the performance of the server, but improves
+  the possible througput of the load-balancer.
+
+10.10.2003 21:09
+- FastCGI - load-balancing
+
+  a brown paper bug has been fixed which caused to decreasing throughput if
+  load-balancing was enabled.
+  
+  
+  benchmarking the req/s with load-balancing shows really nice results:
+
+
+  server   : req/s   comment
+  ---------+--------------------------------------------------
+  ulf      : 764.06  (php)
+  lappi    : 800.06  (php)
+  
+  ulf+lappi: 1526.95 (2 * php)
+  
+  grisu    : 1265.66 (php + ab + lighttpd) 
+  
+  
+  all      : 1647.72 (3 * php + ab + lighttpd)
+  all(nice): 1904.40 (same as all, but the local php on grisu 
+                      has been 'nice -20'd)
+  
+  
+  if a php is run on the load-balancer it has to get a lower priority than
+  the load-balancer itself as to handle the work of (here) 3 php-servers.

+- gigE
+
+  Last week 3 RTL8169S gigE cards arrived and were installed in the
+  test-framework.
+  
+  They are very cheap (20 Euros) and are a good start for a low-level
+  benchmark network. 
+  
+  First result show us:
+  
+  48 Mb/s with ab.
+  
+  The webserver and the test-server are equipped with a 2000+ AMD CPU. The
+  system load 95%, user load is 3%, the rest is idle on both plattforms.
+
+  After some calculations at gets clear that there are various bottlenecks:
+  
+  1. The PCI-Bus (32bit/33Mhz) can only transfer 133Mb/s 
+    - 48 Mb/s TCP-Traffic results in 55Mb/s Ethernet-Traffic (verified with
+      slurm) [outgoing]
+    - there is about 10Mb/s incomming traffic at the PCI bus which the
+      requests
+    - the rest of the devices at the PCI bus are eating the last few mb/s 
+  2. IRQ-Handling
+    - There are reasons why the RTL8169S cards are so cheap
+      - they can't send jumbo-frames
+      - only 8k/64k buffers which results in a interrupt every 3 packets 
+      - they are at least handling checksum offloading for ip, udp and tcp
+      
+  In the end there is a need for new hardware to limit the throughput by the
+  Ethernet again.
+  - PCI-X, 64bit-PCI, ...
+  - 'real' gigE-Network cards
+  - ...
+  
+  
+  BTW: 2.4.22 + the r8139 driver are very flacky and resulted in 3 lock-ups
+  for today. 
+  
+  In another test the dual-PPro-FreeBSD 5.1-CURRENT machine has been used as
+  server with a gigE interface (re0) at has shown that the CPU is the limit
+  for this combination. The maximum thoughput was 7Mb/s.
+  
+  Another small benchmark: 
+  $ ab -n 1000 -c 10 http://192.168.2.41:&lt;port&gt;/lighttpd-20030925.tar
+  
+  port  | server          | CPU Idle 
+  ------+-------­---------+-----------
+  1025  | lighttpd        | 75%
+  1026  | thttpd 2.23b1   | 75%
+  1027  | boa-0.94.14rc17 | 69% *
+  1028  | apache 1.3.x    | 77%
+  
+  
+  In all 4 cases the thoughput was 8600 kbytes/s.
+  
+  * boa had 9 failed transfers.
+  
+- FreeBSD 
+  
+  The problems with FreeBSD 5.0-RELEASE vanished after updating to
+  5.1-CURRENT.

+  the whole fd-event handling has been reworked and several smaller bugs 
+  and design-errors have fixed.
+  
+  sigio, poll() and select() are working fine again.
+  
+  On IRIX 6.5 SIGIO could be used, but without further testing poll() is used.
+  
+- cgi
+  CGI-support is still broken.
+
+21.07.2003 18:46
+- dnotify
+
+  using the F_NOTIFY feautre of the Linux 2.4.x kernel gives anothre nice
+  performance boost as lighttpd can cache the stat()'s the right way, now.
+  
+  23009.66 @ 5-4k-k which means +10% against 30.06.2003 14:03
+  
+  for 1000-4k-nok the performace nearly doubles: 3730.23 goes up to 6144.39
+
+17.07.2003 13:21
+- FreeBSD
+
+  a small patch (#include &lt;&gt;) to compile lighttpd on FreeBSD again.
+  
+08.07.2003 10:48
+- fileinfo-cache
+
+  A reallife test showed that the cache wasn't perfect at all as it made
+  lighttpd crash. This is fixed now.
+
+30.06.2003 17:40
+- lighttpd-bench
+
+  After some problems with other benchmarking tools for webservers the first
+  version of lighttpd-bench has been written.
+  
+  It a revealed a nasty strange behaviour which was fixed by increasing the
+  listen-backlog from 5 to 1024.
+  
+30.06.2003 14:03
+- fileinfo-cache
+
+  the fileinfo-cache has been relaxed a little bit and there are always 2
+  fstat()'s per file-request now. This isn't that dramatic:
+  
+  21800.74 req/s is still a very good result (7-4k-k).
+  
+29.06.2003 03:29
+- fileinfo-cache
+
+  a fileinfo cache has been added to reduce the number of system-calls to
+  stat and open a file. 
+  
+  in the releases before the same file was stat'ed at least 2 times plus a
+  stat on the docroot for each request. Now the stat()'s and the
+  corresponding open() + close() calls are cached and the number of system
+  calls has been reduced to the minimum:
+  
+  $ strace -eopen,stat64,read,write,sendfile,accept,shutdown,close \
+    -p `pidof lighttpd`
+
+/* first connection */
+accept(3, {sin_family=AF_INET6, sin6_port=htons(56211), 
+  inet_pton(AF_INET6, "::ffff:192.168.2.10", &amp;sin6_addr), sin6_flowinfo=0, 
+  sin6_scope_id=0}, [28]) = 5
+accept(3, 0xbffff470, [28])             = -1 EAGAIN
+read(5, "GET /index.html HTTP/1.0\r\nUser-A"..., 4095) = 91

+sendfile(5, 6, [0], 4348)               = 4348
+shutdown(5, 1 /* send */)               = 0
+close(5)                                = 0
+
+/* second connection */
+accept(3, {sin_family=AF_INET6, sin6_port=htons(56212), inet_pton(AF_INET6,
+  "::ffff:192.168.2.10", &amp;sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, [28])

+close(5)                                = 0
+
+
+  In the end we have a new speed record:
+  
+  (ab -c 8 -n 100000 http://192.168.2.10:1025/index.html with poll())
+  Requests per second:    23435.67 [#/sec] (mean)
+  
+  This is a speed increasement of 20-30% against the last internal benchmark.
+
+
+28.06.2003 02:30
+- caching framework 
+
+  the trigger.if directive is working fine. the basic algebra is done ( +,
+  -, *, / and comperations =, &lt;=, &gt;=, &gt;, &lt; and the boolean logic
+  &amp;&amp; and || including braces)
+  
+  two basic function are available:
+  - unix.time.now
+  - file.mtime(...)
+
+25.06.2003 17:33
+- caching framework
+
+  added output.include, output.content-type for a cache-hit and
+  trigger.handler for a cache-miss. 
+  
+  the actual decision is made be trigger.if which will be added tomorrow.
+
+15.06.2003 15:33
+- sig-io 
+
+  After several other smaller optimisations lighttpd performs better with
+  sig-io under high load:
+  
+                  sigio+poll        poll
+  c1000-4k-nok  :    2635.95     1643.39
+  c1000-4k-k    :    7335.68     6788.87
+  c1000-100k-nok:    2353.49     1217.73
+  c1000-100k-k  :    3097.89     2080.73
+  
+  
+  The user-space part has been optimized a lot. Now it is time to optimized
+  the number of context-switches between user and kernel-mode.
+  
+  user    0m0.180s
+  sys     0m1.160s
+  
+  a fileinfo-cache is the way to go.
+  
+  struct {
+  	 buffer *name;
+	 struct stat st;
+	 int handler;
+	 ...
+	 
+	 int fd;
+	 void *mmap_p;
+  }
+
+11.06.2003 14:57
+- sig-io is back again
+
+  and it works fine.
+  
+  sigio (Realtime-Signals under Linux 2.4.x) sends one signal per event and
+  buffers the rest of the events in a kernel queue. If the is full a SIGIO
+  is sent and poll() gets all events at once for further processing.
+  
+  
+  Currently the behaviour is a little bit strange:
+  - sig-io + poll() is good for non-keep-alive connections
+  - poll() for keep-alive connections
+  
+  c1000-4k-nok: (1000 concurrent request, 4k filesize, no keepalive)
+  poll      : 1521.38
+  sigio+poll: 2124.00
+  
+  c1000-4k-k: (1000 concurrent request, 4k filesize, keepalive)
+  poll      : 5882.35
+  sigio+poll: 1239.46
+  
+  Very strange for now. 
+  
+09.06.2003 23:59
+- code-cleanup
+  
+  the event-handling code has been rewritten to handle single events better
+  as they are expected from sig-io.
+  
+  the fallback-mode of sig-io is broken now, but the normal poll() mode got
+  a 10% increasement in speed. This means the we are back the speed level of 
+  20030308-0155 are as fast as zeus again. 
+  
+  Especially under higher load the current lighttpd performes better.

+
+
+For -c 100 4k and 100k sig-io gives a small increasment.  
+
+09.06.2003 01:00 
+- sig-io
+
+  writing large files works now as expected. After removing the limit for
+  the chunks of sendfile the write-buffer-is-empty-again signal is
+  generated. that was missing.
+  
+  321 of 10000 connections still have the wrong length. After that is fixed
+  it is time to start some benchmarks again.
+
+08.06.2003 21:10

+
+
+  as the overall processing cycle has been rearranged the overall figures
+  changed in minor ranges. c100-4k-k increased, *-100k-k decreased.
+  
+  At least it still works.
+
+08.06.2003 12:45
+- select()/poll()
+
+  implementate an abstration layer for fd-events (like eevry other webserver).
+  currently we support poll() and select().
+  
+  This should bring us support for Mac OS X and propably Windows.
+
+04.06.2003 18:35
+- configure
+
+  lighttpd can now be build without ssl-support even if openssl is installed
+
+- protability
+
+  - on IRIX IPv6 is supported now out of the box
+  - for FreeBSD some missing haeders have been added
+
+04.06.2003 14:34
+- pipelining
+  
+  adding support for pipeling introduces a problem if the request-header
+  was broken. this has been fixed now.
+  
+- unneccesary slashes
+
+  when building pathes from different portions of a string (e.g. docroot +
+  virt-server-docroot + request-uri) slashes where added for security and
+  simplicity. This resulted in up to 5 adjacent slashes which caused no harm
+  but looked strange. (fixed)
+
+04.06.2003 09:57
+- start/stop messages
+
+  the error-log contains the start and end-times of the lighttpd process,
+  now.
+  
+- configfile
+
+  the config-file parser has been relaxed to accepts tabs instead of spaces.
+  
+- better error-handling
+
+  fixed a <a 
+  href="http://bugs.php.net/?id=24009">bug in the FastCGI-SAPI of PHP</a>
+  
+  if the fastcgi process dies or closes the connection unexpectedly we
+  return 500 now instead of closing the connection to the client.
+  
+- Location
+
+  the CGI/1.1-rev-03 specification requires us to send Status 302 if a
+  Location-header is sent by the client and a Status-header is missing.
+  
+- PATH_TRANSLATED
+
+  if PHP is compiled without --discard-path PATH_TRANSLATED has to be
+  provided.
+
+27.05.2003 15:54
+- directory listings
+
+  if a directory is requested and the directory doesn't contain a index-file
+  a directory-listing can be displayed. You have to enable directory-listings 
+  in the config-file (directory-listings on)
+
+- url-decoding
+
+  up to know urls where not decoded at all (%26 -> . and so on). This has
+  been added. Unicode isn't supported as we use 8-bit chars internally.
+
+26.05.2003 00:44
+- pipelining
+
+  as Sascha required pipelining for his benchmarking tool it has been
+  implemented. 
+  
+  pipelining allows sending a bunch of requests at once without waiting for
+  the actual responses. This reduces the network-overhead and the
+  round-trip-time.
+  
+- non-free()d memory
+  
+  dmalloc helped to close some non-free()d memory. For the normal operation
+  this isn't important as only memory chunks which had to be free()d at the
+  end of the live-time of the lighttpd-process were not de-allocated.
+  
+- partly-initialized variables
+
+  lighttpd wasn't initializing the main-structure which resulted in strange
+  behaviour in rare circumstances.
+  
+
+25.05.2003 16:23
+- benchmarks
+
+  after removing some useless internal copies we are more or less at the old
+  speed levels.
+  
+  after adding virtual-hosts 10% of the performance were lost. Using less
+  memcpy() operations might add several other boosts.
+  
+  I've just checked how lighttpd compares to Zeus.

+  
+  require   /download/ user=jan|user=anom
+  http-auth /download/ "download archiv" digest

+
+20.05.2003 17:53
+- authentification
+  
+  The auth-methods from RFC 2617 have been added. 
+  - auth basic
+  - auth digest
+  
+  The only source for accounts is currently only the config-file.
+  
+  auth-digest needs the plain-text passwort. Are there any source which
+  provide a plain-text password ?
+
+12.05.2003 14:33

+  virtual-server-default-host grisu.home.kneschke.de:1025
+  virtual-server-docroot /pages/

+  
+  - if http-host exists
+    &lt;virtual-server-root&gt; + &lt;http-host&gt; + &lt;virtual-server-docroot&gt;
+  
+  - otherwise

+- code cleanup
+
+  After two month of development it was time clean-up the internal
+  structures. It looks like every went fine as lighttpd works es expected
+  like before.
+  
+- deflate
+  the on-the-fly compression has been verified to work fine with opera, 
+  konqui, mozilla and the IE.
+
+12.05.2003 02:10
+- on-the-fly compression: deflate 
+ 
+  Why the hell are the defining a "deflate" encoding in the form of
+  
+  _deflate_ The "zlib" format defined in RFC 1950 [31] in combination 
+  with the "deflate" compression mechanism described in RFC 1951 [29]. 
+  (RFC 2616)
+  
+  and noone implements it that way ? Konqui and Mozilla expect a plain
+  deflate() package without the zlib-header. 
+  
+  Konqui is using "inflate2(..., -MAX_WBITS); " which is noted in the zlib
+  source as 
+  
+  /* handle undocumented nowrap option (no zlib header or check) */
+  
+  Funny. Very, very funny.
+  
+  
+  Anyway. We have mimetype-depended compression support now.
+  
+11.05.2003 21:56
+- logging
+  re-arranged the logfile structure to write CLF + useragent + referrer.
+
+11.05.2003 10:23
+- POST file-upload
+  added the missing functionality to send more than a single packet to the
+  FCGI-Server (or Client ? ... the PHP). 
+  
+    This gives us the file-upload thing for eg. PHP and large user-forms
+  (&gt;16kb).
+
+05.05.2003 15:21
+- PATH_INFO
+  
+  added support for PATH_INFO. PHP is a little strange and doesn't trust the
+  passed PATH_INFO setting. 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.
+

+  small comment:
+  lighttpd provides the same performance (req/s and thoughput), but uses more
+  CPU-Time.

+- 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.

+- 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. 
+
+&lt;?php
+
+ob_start(/*"ob_gzhandler"*/);
+print "12345&lt;br /&gt;\n";
+header("Content-Length: ".ob_get_length());
+ob_end_flush();
+
+?&gt;
+
+  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. Just add the chunk to the queue if it
+  is received.
+
+13.03.2003 10:49
+- another set of real-life benchmarks
+  
+  the chairman was benchmarked a little bit. Chairman is full-flegded WCMS.
+  As every CMS it needs some time to generate pages. To speed the page
+  generating the static-parts of the page can be cached internally.
+  
+                     without caching   with caching
+apache + mod_php   :            2.50          10.64 req/s
+lighttpd + fcgi-php:            2.50          22.74 req/s
+
+  Looks like lighttpd is the way to go :)
+
+  Please, don't compare these numbers with the other benchmarks:
+  We used a different test-machine which is a little bit under-powered
+  for this test-case.
+
+12.03.2003 13:43
+- another large application works with lighttpd
+
+  <a
+href="http://www.thinkphp.de/content/content2.php?CatID=44&amp;NewsID=95">Chairman</a> from <a href="http://www.thinkphp.de/">thinkphp</a> has been verified to work with lighttpd. 
+  
+  Three things are worth to note:
+  
+  1. ALWAYS use log_error in the php.ini if you use FastCGI 
+     otherwise it will put the errormessages directly into fastcgi-socket
+     without any FastCGI Header. 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) :    ----
+
+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. It has been verified
+  to compile and work on linux 2.4.x and FreeBSD.
+  
+  
+-c 100
+         sendfile  mmap     read
+4k       6476.68   5698.01  5363.08 [#/sec]
+100k     2312.35    841.54   783.09 [#/sec]
+
+  The mmap() numbers could be better with a fd+mmap-cache. The zero-copy thing
+  is good for our performance.
+  
+- tested another small httpd - BOA
+  just to get a better view about the performance of lighttpd i've tested
+  another httpd: Boa/0.94.14rc16 (http://www.boa.org/)
+  
+                    Boa/0.94.14rc16
+-c 10
+4k                :         5659.63 [#/sec]
+4k (keep-alive)   :          250.23 [#/sec]
+100k              :         1104.29 [#/sec]

+100k (keep-alive) :         1007.05 [#/sec]
+
+  The results are a little bit strange. Keep-Alive for small files seems to be
+  broken.
+
+  It looks like lighttpd has enough power for now. Time the port and add more
+  features.
+
+09.03.2003 13:26
+- load-balancing works great
+
+  I used the framework from http://framework.netuse.de/ as a 
+  real-life example again to test the load-balancer.
+
+  setup:
+  - grisu
+    - AMD athlon XP 2000+
+    - runs lighttpd + ab + a 'nice -15'ed FastCGI-PHP
+    - generates 153 req/s alone
+    
+  - laptop
+    - Intel PIII 850
+    - runs a FastCGI-PHP
+    - generates 88 req/s
+   
+   using the internal load-balancer of lighttpd which balances the 
+   php-requests over grisu and laptop generate:
+     221 req/s
+     
+   An apache with mod_php running on grisu gives 117.04 req/s only.
+
+09.03.2003 12:46
+- building the connect connection to the fcgi-php is not non-blocking
+  socket() -> connect() -> fcntl(non-blocking) resulted in some problems as
+  the connect() call blocked sometimes for 1 seconds. 
+  
+  socket() -> fcntl(non-blocking) -> connect() solves this problem, but
+  addes more overhead. The first connect-attempt seems always to 
+  return EINPROGRESS.
+  
+08.03.2003 15:06
+- the first 'real-life' PHP test showed 2 bugs in the POST handling. 
+  1. the Content-Type header was not forwarded via fastcgi
+  2. the internal content_length handler wasn't reset after the request
+  
+  now lighttpd + php work with
+  
+  http://framework.netuse.de/
+  
+  the basic application gives us 145 req/s 
+
+08.03.2003 11:06
+- use diet to 'test' your code
+  diet gives some use full warnings which should be followed. I took the
+  chance and removed the last few fprintf() and sprintf() from the code.
+  now, we don't need stdio.h anymore.
+  
+    a staticly linked, stripped lighttpd is 42884 bytes large. 
+
+08.03.2003 01:55
+- buffer_strcat() uses strlen() to get the length of the 'to-be-catted-string'
+  if the string is constant or has a known length you can pass that function
+  which gives use buffer_strcat_len() which passes the string length as a
+  parameter.
+  
+- using a ramdisk as the base for the tempfiles generated mkstemp() is a
+  very cood idea 
+  it reduces the io-load on the system and gives as more cpu-time for
+  load-balancing the php-requests.
+  
+- cache the output of strftime(), gmtime() and localtime
+  we generate more then 10.000 req/s which results in using the same
+  timestamp over and over again. It is sufficient to generate the timestamp
+  once a second and give us a bunch of CPU-cycles for sending files.
+
+  the same applies for other timestamps like Last-modified which sends a
+  string version of st.st_mtime. Cache it.
+
+- don't try to overoptimize for code for the sake of clean code
+  the range support require some hack in the first versions like setting the
+  write_offset to the start of the range and keeping the rest of the 
+  "code 200" send code as usual. Only a few lines added this first range 
+  feature. fast, but a hack. It made things more complicated then neccesary 
+  to add multi-range support in this scenario.
+  
+  removing the hack doing small clean preprocessing helps to clean up the
+  whole 'write a chunk on the wire' code. At the end we use less code and
+  have a cleaner design. 
+  
+  Sascha proposed a chunked layer which just takes the chunks (http-header, 
+  part-header, part-message, ... and the last boundary) and passes them to
+  the write-to-the-wire-code. This is far more elegant and will perhaps same
+  us from other problems, too. Currently I think that it is not necessary.
+  First we have to fix some protability issues.
+  
+Ok, today benches:

+so far:
+
+- use state-engines
+
+  a non-forking webserver like described in 
+  
+  http://www.kegel.com/c10k.html
+
+- don't use fprintf() for logging. 
+  writing one line to log file takes more time that sending responsing the a
+  HTTP-request
+  
+- take care of your memory
+
+  typedef struct {
+          char *ptr;
+          size_t used;
+          size_t size;
+  } buffer;
+  
+  buffer* buffer_init();
+  void buffer_free(buffer *b);
+  int buffer_prepare_copy(buffer *b, size_t size);
+  int buffer_prepare_append(buffer *b, size_t size);
+  int buffer_strcpy(buffer *b, const char *s);
+  int buffer_strcpy_len(buffer *b, const char *s, int s_len);
+  int buffer_strcat(buffer *b, const char *s);
+  int buffer_strcat_len(buffer *b, const char *s, int s_len);
+  
+  buffer_init() is only called once per buffer. If you don't need the
+  buffer, set 'used' to zero and reused it afterward. 
+    buffer_strcpy() + buffer_strcat() check if the 'used' + the new strlen()
+  fit in to the 'size' of the buffer. If not the realloc() the buffer.
+    buffer_strcat() uses memcpy(ptr + used - 1, s, s_len + 1); which should
+  be faster than the original strcat().
+  
+  Using those buffers keep the memory usage at 2Mb. malloc() and free() are
+  only called at the beginnig of the programm and at the end.
+  
+- don't used sprintf() to convert a integer into a string as like
+  sprintf(buf, "%d", l);
+  
+  write your own ltostr function. sprintf() is to general for the case and
+  is slow.
