Apart from portability and security fixes, documentation -enhancements, performance improvements, and assorted other minor -features or fixes notable changes are: - - - mod_log_config now supports conditional logging based upon - environment variables and support for multiline entries. - - - New CustomLog directive %V: This logs the hostname according to the - UseCanonicalName setting (this is the pre-1.3.4 behaviour of %v). - - - Enhanced mod_rewrite's mapfile handling: The in-core cache for text - and DBM format mapfiles now uses a hash table with LRU functionality. - Furthermore map lookups for non-existent keys are now cached as well. - The changes drastically improve the performance when large rewrite - maps are in use. - - - Ability to handle DES or MD5 authentication passwords. - - - New <LimitExcept> directive to allow the user to assign authentication - control to any HTTP method that is *not* given in the argument list; - i.e., the logical negation of the <Limit> directive. - - - Improved content negotiation. - - - New ScriptInterpreterSource directive to enable searching the - Win32 registry for script interpreters. - - - The FAQ document was reorganised. - - - Overhauled ApacheBench benchmark program. - - - Several new API functions have been added. - -A complete listing with detailed descriptions is provided in the -src/CHANGES file. - -We consider Apache 1.3.6 to be the best version of Apache available and -we strongly recommend that users of older versions, especially of the -1.1.x and 1.2.x family, upgrade as soon as possible. No further releases -will be made in the 1.2.x family. - - -Apache 1.3.6 is available for download from - - http://www.apache.org/dist/ - -Please see the CHANGES_1.3 file in the same directory for a full -list of changes. - -Binary distributions are available from - - http://www.apache.org/dist/binaries/ - -As of Apache 1.3.6 binary distributions contain all standard Apache -modules as shared objects (if supported by the platform) and include -full source code. Installation is easily done by executing the -included install script. See the README.bindist and INSTALL.bindist -files for a complete explanation. Please note that the binary -distributions are only provided for your convenience and current -distributions for specific platforms are not always available. - -The source and binary distributions are also available via any of the -mirrors listed at - - http://www.apache.org/mirrors/ - -For an overview of new features in 1.3 please see - - http://www.apache.org/docs/new_features_1_3.html - -In general, Apache 1.3 offers several substantial improvements -over version 1.2, including better performance, reliability and a -wider range of supported platforms, including Windows 95/98 and NT -(which fall under the "Win32" label). - -Apache is the most popular web server in the known universe; over -half of the servers on the Internet are running Apache or one of -its variants. - -IMPORTANT NOTE FOR WIN32 USERS: Over the years, many users have -come to trust Apache as a secure and stable server. It must -be realized that the current Win32 code has not yet reached these -levels and should still be considered to be of beta quality. Any -Win32 stability or security problems do not impact, in any way, -Apache on other platforms. With the continued donation of time -and resources by individuals and companies, we hope that the Win32 -version of Apache will grow stronger through the 1.3.x release cycle. - diff --git a/Apache.dsp b/Apache.dsp deleted file mode 100644 index c199b60dcd..0000000000 --- a/Apache.dsp +++ /dev/null @@ -1,109 +0,0 @@ -# Microsoft Developer Studio Project File - Name="Apache" - Package Owner=<4> -# Microsoft Developer Studio Generated Build File, Format Version 5.00 -# ** DO NOT EDIT ** - -# TARGTYPE "Win32 (x86) Console Application" 0x0103 - -CFG=Apache - Win32 Release -!MESSAGE This is not a valid makefile.

Each MPM includes essentially - identical code to ap_register_other_child(), etc. Most of this code can - be moved out of the MPMs and into some common file (http_core.c?). - - * DSO hooks registered during the preflight call to ap_read_config - are not 'unregistered' during the preflight clean-up. Thus, when - Apache comes up, the hook tables contain two entries for each DSO hook, - one of which is bogus, leftover from the preflight. - - * Pipes to CGI scripts are not being timed out - Status: code has been added to APR to support timing out pipes. - This needs to be used in Apache now. - - * Put back resource limit code - - * Port mod_rewrite - Status: Paul Reder <rederpj@raleigh.ibm.com> is working on this. - - * suEXEC doesn't work - Status: Manoj has posted an patch to fix this. - <19991103003605.A20612@samosa.mindspring.com> - - * Win32: Fix Win9* specific code in the winnt MPM - Status: - - * Win32: Test access logging with multiple threads. Will the - native file I/O calls serialize automagically like the - CRT calls or do we need to add region locking each time - we access the logs? - Status: - - * Win32: Smoke test all ported modules to make sure they work - correctly under Windows. - Status: - - * Current 2.0 code is not tested on many Unix platforms. Make 2.0 - work on most, if not all the systems 1.3 did - Status: Autoconf and APR will get us most of the way there. - - * The module API is a weird combination of the old table and the new - hook system. Switch completely to the new hook system - Status: Ben Laurie is working on this. - - * Modules. Which modules do not work yet, can we get a list? - - * We need a thread-safe resolver, at least on Unix. - Status: The best known candidate would be something from BIND - (v8 or v9?) The only other option would be to mutex all the - resolver calls, - -RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP: - - * Win32: Enable the winnt MPM to use the new scoreboard API - - * Win32: Non-blocking CGI pipes - - * Win32: Graceful restart of a service is broken (code does shutdown then start) - - * Dynamically loadable MPMs - Enable users of the binary distributions of Apache to be able to - dynamically load the MPM. - - * Platforms that do not support fork (primarily Win32 and AS/400) - Consider introducing HAVE_FORK feature macro. Architect start-up code - that avoids initializing all the modules in the parent process on - platforms that do not support fork. - - * Clean the code. There are a lot of places we used APR but didn't - remove the hacks that were required for the cross-platform code in - 1.3. We need to make the code look like APR was supposed to be there. - - * Go throught the Bug DB and research the bugs marked "suspended". People - were told these would be considered for inclusion in Apache 2.0, it - would be nice to actually do so. - - * Win32: Migrate the MPM over to use APR thread/process calls. This - would eliminate some code in the Win32 branch that essentially - duplicates what is in APR. - Status: Bill <stoddard@raleigh.ibm.com> is working on this. - - * Move I/O layering into APR. - - * There are still a number of places in the code where we are - loosing error status (i.e. throwing away the error returned by a - system call and replacing it with a generic error code) - - * Win32: Implement reliable piped logs on Windows - Status: Bill <stoddard@raleigh.ibm.com> has prototype code (not - reliable) in 1.3. Should be much cleaner with APR in 2.0. - - * Switch to autoconf, et al. for configuration. - Status: Manoj has placed an initial version into the 2.0 - repository. Todos include: - - - "make install" should work - - a tool to simplfy third-party module building should be - written. Something like apxs - - Add a lot more checks to satisfy the various platforms, e.g. - for threading - - * Use APR to get rid of more platform dependancies. - Status: Ryan Bloom <rbb@raleigh.ibm.com> is working on this. - - * The connection status table is not very efficient. Also, very few stats - are exported to the connection status table (easy to fix), and mod_status - is ugly. - -Other bugs that need fixing: - - * MaxRequestsPerChild measures connections, not requests. - Until someone has a better way, we'll probably just rename it - "MaxConnectionsPerChild". - - * Regex containers don't work in an intutive way - Status: No one has come up with an efficient way to fix this - behavior. Dean has suggested getting rid of regex containers - completely. - - * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a - sigwaiting thread. We need to work around this, perhaps unless - there is hope soon for a fixed glibc. - -Other features that need writing: - - * Finish infrastructure in core for async MPMs - Status: ? - - * TODO in source -- just do an egrep on "TODO" and see what's there - - * Work on other MPMs. Possible MPMs discussed or in progress include: - - - Dean Gaudet's async MPM - Status: dean is unlikely to begin work on this any time soon... - has lots of ideas he'll share with folks willing to begin - tackling the issues. this is apache 2.1 material. - - - Zach Brown's <zab@zabbo.net> Linux siginfo MPM - Status: ? - -Documentation that needs writing: - - * The concept of MPMs, especially if we ship more than one MPM for a - given platform - - * New directives in the various MPMs - - * API documentation - Status: Ben Laurie has written some hooks documentation - (apache-2.0/htdocs/hooks.html) - - * Changes since 1.3.9 can be more easily seen in the commitlog file - dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0 - which includes some of Roy's comments when the changes were - committed in rough change-sets by purpose.

Directives that control the operation of the Apache server process as a -# whole (the 'global environment'). -# 2. Directives that define the parameters of the 'main' or 'default' server, -# which responds to requests that aren't handled by a virtual host. -# These directives also provide default values for the settings -# of all virtual hosts. -# 3. Settings for virtual hosts, which allow Web requests to be sent to -# different IP addresses or hostnames and have them handled by the -# same Apache server process. -# -# Configuration and logfile names: If the filenames you specify for many -# of the server's control files begin with "/" (or "drive:/" for Win32), the -# server will use that explicit path. If the filenames do *not* begin -# with "/", the value of ServerRoot is prepended -- so "logs/foo.log" -# with ServerRoot set to "/usr/local/apache" will be interpreted by the -# server as "/usr/local/apache/logs/foo.log". -# -# NOTE: Where filenames are specified, you must use forward slashes -# instead of backslashes (e.g., "c:/apache" instead of "c:\apache"). -# If a drive letter is omitted, the drive on which Apache.exe is located -# will be used by default. It is recommended that you always supply -# an explicit drive letter in absolute paths, however, to avoid -# confusion. -# - -### Section 1: Global Environment -# -# The directives in this section affect the overall operation of Apache, -# such as the number of concurrent requests it can handle or where it -# can find its configuration files. -# - -# -# ServerType is either inetd, or standalone.

The latter two files are -# now distributed empty, as it is recommended that all directives -# be kept in a single file for simplicity. The commented-out values -# below are the built-in defaults. You can have the server ignore -# these files altogether by using "/dev/null" (for Unix) or -# "nul" (for Win32) for the arguments to the directives. -# -#ResourceConfig conf/srm.conf -#AccessConfig conf/access.conf - -# -# Timeout: The number of seconds before receives and sends time out. -# -Timeout 300 - -# -# KeepAlive: Whether or not to allow persistent connections (more than -# one request per connection).

The next two -# directives control the behaviour of the threads and processes. -# - -# -# MaxRequestsPerChild: the number of requests each child process is -# allowed to process before the child dies. The child will exit so -# as to avoid problems after prolonged use when Apache (and maybe the -# libraries it uses) leak memory or other resources.

It is designed to give you an impression on how performant is your -current Apache installation. This especially shows you how much requests per -time your Apache installation is capable to serve. -.PP -.SH OPTIONS -.TP 12 -.B \-k -Enable the HTTP KeepAlive feature, i.e. perform multiple requests within one -HTTP session instead. Default is no KeepAlive. -.TP 12 -.BI \-n " requests" -Number of requests to perform for the benchmarking session. The default is to -just perform one single request which usually leads to not very representative -benchmarking results. -.TP 12 -.BI \-t " timelimit" -Seconds to max. spend for benchmarking. This implies -a -.B \-n -.B 50000 -internally. Use this to benchmark the server within a fixed total amount of -time. Per default there is no timelimit. -.TP 12 -.BI \-c " concurrency" -Number of multiple requests per time to perform. -Default is one request per time. - -.TP 12 -.BI \-p " POST file" -File containing data to POST. - -.TP 12 -.BI \-A " Authorization username:password" -Supply BASIC Authentification credentials to the server. The username -and password are separated by a single ':' and send on the wire uuencoded. -The string is send regardless of wether the server needs it; (i.e. has -send an 401. Authentifcation needed). - -.TP 12 -.BI \-p " Proxy-Authorization username:password" -Supply BASIC Authentification credentials to a proxy en-route. The username -and password are separated by a single ':' and send on the wire uuencoded. -The string is send regardless of wether the proxy needs it; (i.e. has -send an 407 Proxy authentifcation needed). - -.TP 12 -.BI \-C " Cookie name=value" -Add a 'Cookie:' line to the request. The argument is typically in the form -of a 'name=value' pair. This field is repeatable. - -.TP 12 -.BI \-p " Header string" -Postfix extra headers to the request. The argument is typically in the form -of a valid header line; containing a colon separated field value pair. (i.e. -'Accept-Encoding: zip/zop;8bit'). - -.TP 12 -.BI \-T " content-type" -Content-type header to use for POST data. - -.TP 12 -.B \-v -Set verbosity level - 4 and above prints information on headers, 3 and -above prints response codes (404, 200, etc.), 2 and above prints -warnings and info. - -.TP 12 -.BI \-w -Print out results in HTML tables. Default table is two columns wide, -with a white background. -.TP 12 -.BI \-x " attributes" -String to use as attributes for <table>. Attributes are inserted -<table -.B here -> -.TP 12 -.BI \-y " attributes" -String to use as attributes for <tr>. -.TP 12 -.BI \-z " attributes" -String to use as attributes for <td>. -.TP 12 -.B \-V -Display version number and exit. -.TP 12 -.B \-h -Display usage information. -.PD -.SH BUGS -There are various statically declared buffers of fixed length. Combined -with the lazy parsing of the command line arguments, the response headers -from the server and other external inputs this might bite you. -.P -It does not implement HTTP/1.x fully; only accepts some 'expected' forms -of responses. The rather heavy use of -.BR strstr(3) -shows up top in profile, -which might indicate a performance problem; i.e. you would measure the -.BR ab -performance rather than the server's. - -.SH SEE ALSO -.BR httpd(8) -. diff --git a/docs/man/apachectl.8 b/docs/man/apachectl.8 deleted file mode 100644 index 72300eb98b..0000000000 --- a/docs/man/apachectl.8 +++ /dev/null @@ -1,133 +0,0 @@ -.TH apachectl 1 "September 1997" -.\" Copyright (c) 1997-1999 The Apache Group.

It is designed to help the administrator control the -functioning of the Apache -.B httpd -daemon. -.PP -.B NOTE: -If your Apache installation uses non-standard paths, you will need to -edit the -.B apachectl -script to set the appropriate paths to your PID file and your -.B httpd -binary. See the comments in the script for details. -.PP -The -.B apachectl -script returns a 0 exit value on success, and >0 if an error -occurs. For more details, view the comments in the script. -.PP -Full documentation for Apache is available at -.B http://www.apache.org/ -. -.SH OPTIONS -The \fIcommand\fP can be any one or more of the following options: -.TP 12 -.BI start -Start the Apache daemon. Gives an error if it is already running. -.TP -.BI stop -Stops the Apache daemon. -.TP -.BI restart -Restarts the Apache daemon by sending it a SIGHUP. If the daemon -is not running, it is started. -This command automatically checks the configuration files via -.BI configtest -before initiating the restart to make sure Apache doesn't die. -.TP -.BI fullstatus -Displays a full status report from -.B mod_status. -For this to work, you need to have mod_status enabled on your server -and a text-based browser such as \fIlynx\fP available on your system. The -URL used to access the status report can be set by editing the -.B STATUSURL -variable in the script. -.TP -.BI status -Displays a brief status report. Similar to the fullstatus option, -except that the list of requests currently being served is omitted. -.TP -.BI graceful -Gracefully restarts the Apache daemon by sending it a SIGUSR1. If -the daemon is not running, it is started. This differs from a -normal restart in that currently open connections are not aborted. -A side effect is that old log files will not be closed immediately. -This means that if used in a log rotation script, a substantial delay may be -necessary to ensure that the old log files are closed before processing them. -This command automatically checks the configuration files via -.BI configtest -before initiating the restart to make sure Apache doesn't die. -.TP -.BI configtest -Run a configuration file syntax test. It parses the configuration -files and either reports -.B "Syntax Ok" -or detailed information about the particular syntax error. -.TP -.BI help -Displays a short help message. -.SH SEE ALSO -.BR httpd(8) -. diff --git a/docs/man/apxs.8 b/docs/man/apxs.8 deleted file mode 100644 index 464766c75f..0000000000 --- a/docs/man/apxs.8 +++ /dev/null @@ -1,459 +0,0 @@ -.TH apxs 8 "April 1998" -.\" Copyright (c) 1998-1999 The Apache Group.

This is achieved by building a -dynamic shared object (DSO) from one or more source or object -.I files -which then can be loaded into -the Apache server under runtime via the -.B LoadModule -directive from -.BR mod_so. - -So to use this extension mechanism your platform has -to support the DSO feature and your -Apache -.B httpd -binary has to be built with the -.B mod_so -module. -The -.B apxs -tool automatically complains if this is not the case. -You can check this yourself by manually running the command - -.nf - $ httpd -l -.fi - -The module -.B mod_so -should be part of the displayed list. -If these requirements are fulfilled you can easily extend -your Apache server's functionality by installing your own -modules with the DSO mechanism by the help of this -.B apxs -tool: - -.nf - $ apxs -i -a -c mod_foo.c - gcc -fpic -DSHARED_MODULE -I/path/to/apache/include -c mod_foo.c - ld -Bshareable -o mod_foo.so mod_foo.o - cp mod_foo.so /path/to/apache/libexec/mod_foo.so - chmod 755 /path/to/apache/libexec/mod_foo.so - [activating module `foo' in /path/to/apache/etc/httpd.conf] - $ apachectl restart - /path/to/apache/sbin/apachectl restart: httpd not running, trying to start - [Tue Mar 31 11:27:55 1998] [debug] mod_so.c(303): loaded module foo_module - /path/to/apache/sbin/apachectl restart: httpd started - $ _ -.fi - -The arguments -.I files -can be any C source file (.c), a object file (.o) or -even a library archive (.a). The -.B apxs -tool automatically recognizes these extensions and automtaically used the C -source files for compilation while just using the object and archive files for -the linking phase. But when using such pre-compiled objects make sure they are -compiled for position independend code (PIC) to be able to use them for a -dynamically loaded shared object. -For instance with GCC you always just have to use -.BR -fpic . -For other -C compilers consult its manual -page or at watch for the flags -.B apxs -uses to compile the object files. - -For more details about DSO support in Apache read the documentation -of -.B mod_so -or perhaps even read the -.B src/modules/standard/mod_so.c -source file. - -.PP -.SH OPTIONS -Common options: -.TP 12 -.BI \-n " modname" -This explicitly sets the module name for the -.B \-i -(install) -and -.B \-g -(template generation) option. Use this to explicitly specify the module name. -For option -.B \-g -this is required, for option -.B \-i -the -.B apxs -tool tries to determine the name from the source or (as a fallback) at least -by guessing it from the filename. -.PP -Query options: -.TP 12 -.B \-q -Performs a query for -.BR apxs 's -knowledge about certain settings. The -.I query -parameters can be one or more of the following strings: -.nf - CC TARGET - CFLAGS SBINDIR - CFLAGS_SHLIB INCLUDEDIR - LD_SHLIB LIBEXECDIR - LDFLAGS_SHLIB SYSCONFDIR - LIBS_SHLIB -.fi -Use this for manually determining settings. For instance use -.nf - INC=-I`apxs -q INCLUDEDIR` -.fi -inside your own Makefiles if you need manual access -to Apache's C header files. -.PP -Configuration options: -.TP 12 -.BI \-S " name=value" -This option changes the apxs settings described above. -.PP -Template Generation options: -.TP 12 -.B \-g -This generates a subdirectory -.I name -(see option -.BR \-n ")" -and there two files: A sample module source file named -.BI mod_ name.c -which can be used as a template for creating your own modules or -as a quick start for playing with the APXS mechanism. -And a corresponding -.B Makefile -for even easier build and installing of this module. -.PP -DSO compilation options: -.TP 12 -.B \-c -This indicates the compilation operation. It first compiles the C source -files (.c) of -.I files -into corresponding object files (.o) and then builds a dynamically shared object in -.I dsofile -by linking these object files plus the remaining -object files (.o and .a) of -.I files -If no -.B \-o -option is specified -the output file is guessed from the first filename in -.I files -and thus usually defaults to -.BI mod_ name.so -.TP 12 -.BI \-o " dsofile" -Explicitly specifies the filename of the created dynamically shared object. If -not specified and the name cannot be guessed from the -.I files -list, the fallback name -.B mod_unknown.so -is used. -.TP 12 -.BI \-D " name=value" -This option is directly passed through to the compilation command(s). -Use this to add your own defines to the build process. -.TP 12 -.BI \-I " incdir" -This option is directly passed through to the compilation command(s). -Use this to add your own include directories to search to the build process. -.TP 12 -.BI \-L " libdir" -This option is directly passed through to the linker command. -Use this to add your own library directories to search to the build process. -.TP 12 -.BI \-l " libname" -This option is directly passed through to the linker command. -Use this to add your own libraries to search to the build process. -.TP 12 -.BI \-Wc, "compiler-flags" -This option passes -.I compiler-flags -as additional flags to the compiler command. -Use this to add local compiler-specific options. -.TP 12 -.BI \-Wl, "linker-flags" -This option passes -.I linker-flags -as additional flags to the linker command. -Use this to add local linker-specific options. -.PP -DSO installation and configuration options: -.TP 12 -.B \-i -This indicates the installation operation and installs one or more -dynamically shared objects into the -server's -.I libexec -directory. -.TP 12 -.B \-a -This activates the module by automatically adding a corresponding -.B LoadModule -line to Apache's -.B httpd.conf -configuration file, or by enabling it if it already exists. -.TP 12 -.B \-A -Same as option -.B \-a -but the created -.B LoadModule -directive is prefixed with a hash sign (#), i.e. the module is -just prepared for later activation but initially disabled. -.TP 12 -.B \-e -This indicates the editing operation, which can be used with the -.B \-a -and -.B \-A -options similarly to the -.B \-i -operation to edit Apache's -.B httpd.conf -configuration file without attempting to install the module. -.PD -.SH EXAMPLES -Assume you have an Apache module named mod_foo.c available which should extend -Apache's server functionality. To accomplish this you first have to compile -the C source into a shared object suitable for loading into the Apache server -under runtime via the following command: - -.nf - $ apxs -c mod_foo.c - gcc -fpic -DSHARED_MODULE -I/path/to/apache/include -c mod_foo.c - ld -Bshareable -o mod_foo.so mod_foo.o - $ _ -.fi - -Then you have to update the Apache configuration by making sure a -.B LoadModule -directive is present to load this shared object. To simplify this -step -.B apxs -provides an automatic way to install the shared object in its -"libexec" directory and updating the -.B httpd.conf -file accordingly. This can be achieved by running: - -.nf - $ apxs -i -a mod_foo.c - cp mod_foo.so /path/to/apache/libexec/mod_foo.so - chmod 755 /path/to/apache/libexec/mod_foo.so - [activating module `foo' in /path/to/apache/etc/httpd.conf] - $ _ -.fi - -This way a line named - -.nf - LoadModule foo_module libexec/mod_foo.so -.fi - -is added to the configuration file if still not present. -If you want to have this this disabled per default use the -.B \-A -option, i.e. - -.nf - $ apxs -i -A mod_foo.c -.fi - -For a quick test of the APXS mechanism you can create a sample Apache module -template plus a corresponding Makefile via: - -.nf - $ apxs -g -n foo - Creating [DIR] foo - Creating [FILE] foo/Makefile - Creating [FILE] foo/mod_foo.c - $ _ -.fi - -Then you can immediately compile this sample module into a shared object and -load it into the Apache server: - -.nf - $ cd foo - $ make all reload - apxs -c mod_foo.c - gcc -fpic -DSHARED_MODULE -I/path/to/apache/include -c mod_foo.c - ld -Bshareable -o mod_foo.so mod_foo.o - apxs -i -a -n "foo" mod_foo.so - cp mod_foo.so /path/to/apache/libexec/mod_foo.so - chmod 755 /path/to/apache/libexec/mod_foo.so - [activating module `foo' in /path/to/apache/etc/httpd.conf] - apachectl restart - /path/to/apache/sbin/apachectl restart: httpd not running, trying to start - [Tue Mar 31 11:27:55 1998] [debug] mod_so.c(303): loaded module foo_module - /path/to/apache/sbin/apachectl restart: httpd started - $ _ -.fi - -You can even use -.B apxs -to compile complex modules outside the Apache source tree, like PHP3: - -.nf - $ cd php3 - $ ./configure --with-shared-apache=../apache-1.3 - $ apxs -c -o libphp3.so mod_php3.c libmodphp3-so.a - gcc -fpic -DSHARED_MODULE -I/tmp/apache/include -c mod_php3.c - ld -Bshareable -o libphp3.so mod_php3.o libmodphp3-so.a - $ _ -.fi - -because -.B apxs -automatically recognized C source files and object files.

For details of -the directives necessary to configure user authentication in -.B httpd -see -the Apache manual, which is part of the Apache distribution or can be -found at http://www.apache.org/. -.SH OPTIONS -.IP \fB\fIfilename\fP -The filename of the DBM format file. Usually without the -extension .db, .pag, or .dir. -.IP \fB\fIcommand\fP -This selects the operation to perform: -.TP 12 -.B add -Adds an entry for \fIusername\fP to \fIfilename\fP using the encrypted -password \fIencpassword\fP. -.TP 12 -.B adduser -Asks for a password and then adds an entry for \fIusername\fP to -\fIfilename\fP . -.TP 12 -.B check -Asks for a password and then checks if -\fIusername\fP is in \fIfilename\fP and if it's password matches -the specified one. -.TP 12 -.B delete -Deletes the \fIusername\fP entry from \fIfilename\fP. -.TP 12 -.B import -Reads username:password entries (one per line) from STDIN and adds them to -\fIfilename\fP.

The three primary examples are -NDBM, the GNU project's GDBM, and Berkeley DB 2. Unfortunately, all -these libraries use different file formats, and you must make sure -that the file format used by -.I filename -is the same format that -.B dbmmanage -expects to see. -.B dbmmanage -currently has no way of determining what type of DBM file it is -looking at. If used against the wrong format, -.dbmmanage -will simply return nothing, or may create a different DBM file with a -different name, or at worst, it may corrupt the DBM file if you were -attempting to write to it. -.PP -.B dbmmanage -has a list of DBM format preferences, defined by the -.B @AnyDBM::ISA -array near the beginning of the program. Since we prefer the Berkeley -DB 2 file format, the order in which -.B dbmmanage -will look for system libraries is Berkeley DB 2, then NDBM, and then -GDBM. The first library found will be the library -.B dbmmanage -will attempt to use for all DBM file transactions. This ordering is -slightly different than the standard -.B @AnyDBM::ISA -ordering in perl, as well as the ordering used by the simple dbmopen() -call in Perl, so if you use any other utilities to manage your DBM -files, they must also follow this preference ordering. Similar care -must be taken if using programs in other languages, like C, to -access these files. -.PP -Apache's -.B mod_auth_db.c -module corresponds to Berkeley DB 2 library, while -.B mod_auth_dbm.c -corresponds to the NDBM library. Also, one can usually use the -.B file -program supplied with most Unix systems to see what format a DBM file is in. -.PD -.SH SEE ALSO -.BR httpd(8) -. diff --git a/docs/man/htdigest.1 b/docs/man/htdigest.1 deleted file mode 100644 index c719e456ce..0000000000 --- a/docs/man/htdigest.1 +++ /dev/null @@ -1,97 +0,0 @@ -.TH htdigest 1 "March 1998" -.\" Copyright (c) 1997-1999 The Apache Group.

One way of selecting the most -appropriate choice is to give the user an index page, and let them -select. However it is often possible for the server to choose -automatically. This works because browsers can send as part of each -request information about what representations they prefer. For -example, a browser could indicate that it would like to see -information in French, if possible, else English will do. Browsers -indicate their preferences by headers in the request. To request only -French representations, the browser would send - -<PRE> - Accept-Language: fr -</PRE> - -<P> -Note that this preference will only be applied when there is a choice -of representations and they vary by language. -<P> - -As an example of a more complex request, this browser has been -configured to accept French and English, but prefer French, and to -accept various media types, preferring HTML over plain text or other -text types, and preferring GIF or JPEG over other media types, but also -allowing any other media type as a last resort: - -<PRE> - Accept-Language: fr; q=1.0, en; q=0.5 - Accept: text/html; q=1.0, text/*; q=0.8, image/gif; q=0.6, - image/jpeg; q=0.6, image/*; q=0.5, */*; q=0.1 -</PRE> - -Apache 1.2 supports 'server driven' content negotiation, as defined in -the HTTP/1.1 specification. It fully supports the Accept, -Accept-Language, Accept-Charset and Accept-Encoding request headers. -Apache 1.3.4 also supports 'transparent' content negotiation, which is -an experimental negotiation protocol defined in RFC 2295 and RFC 2296. -It does not offer support for 'feature negotiation' as defined in -these RFCs. -<P> - -A <STRONG>resource</STRONG> is a conceptual entity identified by a URI -(RFC 2396). An HTTP server like Apache provides access to -<STRONG>representations</STRONG> of the resource(s) within its namespace, -with each representation in the form of a sequence of bytes with a -defined media type, character set, encoding, etc. Each resource may be -associated with zero, one, or more than one representation -at any given time. If multiple representations are available, -the resource is referred to as <STRONG>negotiable</STRONG> and each of its -representations is termed a <STRONG>variant</STRONG>. The ways in which the -variants for a negotiable resource vary are called the -<STRONG>dimensions</STRONG> of negotiation. - -<H2>Negotiation in Apache</H2> - -<P> -In order to negotiate a resource, the server needs to be given -information about each of the variants. This is done in one of two -ways: - -<UL> - <LI> Using a type map (<EM>i.e.</EM>, a <CODE>*.var</CODE> file) which - names the files containing the variants explicitly, or - <LI> Using a 'MultiViews' search, where the server does an implicit - filename pattern match and chooses from among the results. -</UL> - -<H3>Using a type-map file</H3> - -<P> -A type map is a document which is associated with the handler -named <CODE>type-map</CODE> (or, for backwards-compatibility with -older Apache configurations, the mime type -<CODE>application/x-type-map</CODE>). Note that to use this feature, -you must have a handler set in the configuration that defines a -file suffix as <CODE>type-map</CODE>; this is best done with a - -<PRE> - AddHandler type-map var -</PRE> - -in the server configuration file. See the comments in the sample config -file for more details. <P> - -Type map files have an entry for each available variant; these entries -consist of contiguous HTTP-format header lines. Entries for -different variants are separated by blank lines. Blank lines are -illegal within an entry. It is conventional to begin a map file with -an entry for the combined entity as a whole (although this -is not required, and if present will be ignored). An example -map file is: - -<PRE> - URI: foo - - URI: foo.en.html - Content-type: text/html - Content-language: en - - URI: foo.fr.de.html - Content-type: text/html;charset=iso-8859-2 - Content-language: fr, de -</PRE> - -If the variants have different source qualities, that may be indicated -by the "qs" parameter to the media type, as in this picture (available -as jpeg, gif, or ASCII-art): - -<PRE> - URI: foo - - URI: foo.jpeg - Content-type: image/jpeg; qs=0.8 - - URI: foo.gif - Content-type: image/gif; qs=0.5 - - URI: foo.txt - Content-type: text/plain; qs=0.01 -</PRE> -<P> - -qs values can vary in the range 0.000 to 1.000. Note that any variant with -a qs value of 0.000 will never be chosen. Variants with no 'qs' -parameter value are given a qs factor of 1.0. The qs parameter indicates -the relative 'quality' of this variant compared to the other available -variants, independent of the client's capabilities. For example, a jpeg -file is usually of higher source quality than an ascii file if it is -attempting to represent a photograph. However, if the resource being -represented is an original ascii art, then an ascii representation would -have a higher source quality than a jpeg representation. A qs value -is therefore specific to a given variant depending on the nature of -the resource it represents. - -<P> -The full list of headers recognized is: - -<DL> - <DT> <CODE>URI:</CODE> - <DD> uri of the file containing the variant (of the given media - type, encoded with the given content encoding).

Note that -<CODE>Options All</CODE> does not set <CODE>MultiViews</CODE>; you -have to ask for it by name. - -<P> -The effect of <CODE>MultiViews</CODE> is as follows: if the server -receives a request for <CODE>/some/dir/foo</CODE>, if -<CODE>/some/dir</CODE> has <CODE>MultiViews</CODE> enabled, and -<CODE>/some/dir/foo</CODE> does <EM>not</EM> exist, then the server reads the -directory looking for files named foo.*, and effectively fakes up a -type map which names all those files, assigning them the same media -types and content-encodings it would have if the client had asked for -one of them by name. It then chooses the best match to the client's -requirements. - -<P> -<CODE>MultiViews</CODE> may also apply to searches for the file named by the -<CODE>DirectoryIndex</CODE> directive, if the server is trying to -index a directory. If the configuration files specify - -<PRE> - DirectoryIndex index -</PRE> - -then the server will arbitrate between <CODE>index.html</CODE> -and <CODE>index.html3</CODE> if both are present. If neither are -present, and <CODE>index.cgi</CODE> is there, the server will run it. - -<P> -If one of the files found when reading the directive is a CGI script, -it's not obvious what should happen. The code gives that case -special treatment --- if the request was a POST, or a GET with -QUERY_ARGS or PATH_INFO, the script is given an extremely high quality -rating, and generally invoked; otherwise it is given an extremely low -quality rating, which generally causes one of the other views (if any) -to be retrieved. - -<H2>The Negotiation Methods</H2> - -After Apache has obtained a list of the variants for a given resource, -either from a type-map file or from the filenames in the directory, it -invokes one of two methods to decide on the 'best' variant to -return, if any.

This negotiation method gives the browser full control over -deciding on the 'best' variant, the result is therefore dependent on -the specific algorithms used by the browser. As part of the -transparent negotiation process, the browser can ask Apache to run the -'remote variant selection algorithm' defined in RFC 2296. </UL> - - -<H3>Dimensions of Negotiation</H3> - -<TABLE> -<TR valign="top"> -<TH>Dimension -<TH>Notes -<TR valign="top"> -<TD>Media Type -<TD>Browser indicates preferences with the Accept header field.

This algorithm is not -further configurable. It operates as follows: - -<OL> -<LI>First, for each dimension of the negotiation, check the appropriate -<EM>Accept*</EM> header field and assign a quality to each -variant.

If more than one -variant remains, move on to the next test. - -<OL> -<LI>Multiply the quality factor from the Accept header with the - quality-of-source factor for this variant's media type, and select - the variants with the highest value. - -<LI>Select the variants with the highest language quality factor. - -<LI>Select the variants with the best language match, using either the - order of languages in the Accept-Language header (if present), or else - else the order of languages in the <CODE>LanguagePriority</CODE> - directive (if present). - -<LI>Select the variants with the highest 'level' media parameter - (used to give the version of text/html media types). - -<LI>Select variants with the best charset media parameters, - as given on the Accept-Charset header line. Charset ISO-8859-1 - is acceptable unless explicitly excluded. Variants with a - <CODE>text/*</CODE> media type but not explicitly associated - with a particular charset are assumed to be in ISO-8859-1. - -<LI>Select those variants which have associated - charset media parameters that are <EM>not</EM> ISO-8859-1. - If there are no such variants, select all variants instead. - -<LI>Select the variants with the best encoding. If there are - variants with an encoding that is acceptable to the user-agent, - select only these variants. Otherwise if there is a mix of encoded - and non-encoded variants, select only the unencoded variants. - If either all variants are encoded or all variants are not encoded, - select all variants. - -<LI>Select the variants with the smallest content length. - -<LI>Select the first variant of those remaining.

This is to get a better result from the algorithm for -browsers which do not send full or accurate information. Some of the -most popular browsers send Accept header information which would -otherwise result in the selection of the wrong variant in many -cases. If a browser sends full and correct information these fiddles -will not be applied. -<P> - -<H3>Media Types and Wildcards</H3> - -<P> -The Accept: request header indicates preferences for media types. It -can also include 'wildcard' media types, such as "image/*" or "*/*" -where the * matches any string. So a request including: -<PRE> - Accept: image/*, */* -</PRE> - -would indicate that any type starting "image/" is acceptable, -as is any other type (so the first "image/*" is redundant). Some -browsers routinely send wildcards in addition to explicit types they -can handle. For example: -<PRE> - Accept: text/html, text/plain, image/gif, image/jpeg, */* -</PRE> - -The intention of this is to indicate that the explicitly -listed types are preferred, but if a different representation is -available, that is ok too. However under the basic algorithm, as given -above, the */* wildcard has exactly equal preference to all the other -types, so they are not being preferred. The browser should really have -sent a request with a lower quality (preference) value for *.*, such -as: -<PRE> - Accept: text/html, text/plain, image/gif, image/jpeg, */*; q=0.01 -</PRE> - -The explicit types have no quality factor, so they default to a -preference of 1.0 (the highest). The wildcard */* is given -a low preference of 0.01, so other types will only be returned if -no variant matches an explicitly listed type. -<P> - -If the Accept: header contains <EM>no</EM> q factors at all, Apache sets -the q value of "*/*", if present, to 0.01 to emulate the desired -behavior. It also sets the q value of wildcards of the format -"type/*" to 0.02 (so these are preferred over matches against -"*/*". If any media type on the Accept: header contains a q factor, -these special values are <EM>not</EM> applied, so requests from browsers -which send the correct information to start with work as expected. - -<H3>Variants with no Language</H3> - -<P> -If some of the variants for a particular resource have a language -attribute, and some do not, those variants with no language -are given a very low language quality factor of 0.001.<P> - -The reason for setting this language quality factor for -variant with no language to a very low value is to allow -for a default variant which can be supplied if none of the -other variants match the browser's language preferences. - -For example, consider the situation with three variants: - -<UL> -<LI>foo.en.html, language en -<LI>foo.fr.html, language en -<LI>foo.html, no language -</UL> - -<P> -The meaning of a variant with no language is that it is -always acceptable to the browser. If the request Accept-Language -header includes either en or fr (or both) one of foo.en.html -or foo.fr.html will be returned. If the browser does not list -either en or fr as acceptable, foo.html will be returned instead. - -<H2>Extensions to Transparent Content Negotiation</H2> - -Apache extends the transparent content negotiation protocol (RFC 2295) -as follows. A new <CODE> {encoding ..}</CODE> element is used in -variant lists to label variants which are available with a specific -content-encoding only. The implementation of the -RVSA/1.0 algorithm (RFC 2296) is extended to recognize encoded -variants in the list, and to use them as candidate variants whenever -their encodings are acceptable according to the Accept-Encoding -request header. The RVSA/1.0 implementation does not round computed -quality factors to 5 decimal places before choosing the best variant. - -<H2>Note on hyperlinks and naming conventions</H2> - -<P> -If you are using language negotiation you can choose between -different naming conventions, because files can have more than one -extension, and the order of the extensions is normally irrelevant -(see <A HREF="mod/mod_mime.html">mod_mime</A> documentation for details). -<P> -A typical file has a MIME-type extension (<EM>e.g.</EM>, <SAMP>html</SAMP>), -maybe an encoding extension (<EM>e.g.</EM>, <SAMP>gz</SAMP>), and of course a -language extension (<EM>e.g.</EM>, <SAMP>en</SAMP>) when we have different -language variants of this file. - -<P> -Examples: -<UL> -<LI>foo.en.html -<LI>foo.html.en -<LI>foo.en.html.gz -</UL> - -<P> -Here some more examples of filenames together with valid and invalid -hyperlinks: -</P> - -<TABLE BORDER=1 CELLPADDING=8 CELLSPACING=0> -<TR> - <TH>Filename</TH> - <TH>Valid hyperlink</TH> - <TH>Invalid hyperlink</TH> -</TR> -<TR> - <TD><EM>foo.html.en</EM></TD> - <TD>foo<BR> - foo.html</TD> - <TD>-</TD> -</TR> -<TR> - <TD><EM>foo.en.html</EM></TD> - <TD>foo</TD> - <TD>foo.html</TD> -</TR> -<TR> - <TD><EM>foo.html.en.gz</EM></TD> - <TD>foo<BR> - foo.html</TD> - <TD>foo.gz<BR> - foo.html.gz</TD> -</TR> -<TR> - <TD><EM>foo.en.html.gz</EM></TD> - <TD>foo</TD> - <TD>foo.html<BR> - foo.html.gz<BR> - foo.gz</TD> -</TR> -<TR> - <TD><EM>foo.gz.html.en</EM></TD> - <TD>foo<BR> - foo.gz<BR> - foo.gz.html</TD> - <TD>foo.html</TD> -</TR> -<TR> - <TD><EM>foo.html.gz.en</EM></TD> - <TD>foo<BR> - foo.html<BR> - foo.html.gz</TD> - <TD>foo.gz</TD> -</TR> -</TABLE> - -<P> -Looking at the table above you will notice that it is always possible to -use the name without any extensions in an hyperlink (<EM>e.g.</EM>, <SAMP>foo</SAMP>). -The advantage is that you can hide the actual type of a -document rsp. file and can change it later, <EM>e.g.</EM>, from <SAMP>html</SAMP> -to <SAMP>shtml</SAMP> or <SAMP>cgi</SAMP> without changing any -hyperlink references. - -<P> -If you want to continue to use a MIME-type in your hyperlinks (<EM>e.g.</EM> -<SAMP>foo.html</SAMP>) the language extension (including an encoding extension -if there is one) must be on the right hand side of the MIME-type extension -(<EM>e.g.</EM>, <SAMP>foo.html.en</SAMP>). - - -<H2>Note on Caching</H2> - -<P> -When a cache stores a representation, it associates it with the request URL. -The next time that URL is requested, the cache can use the stored -representation.

The resource -pool machinery is designed to make it easy to prevent this from -happening, by allowing resource to be allocated in such a way that -they are <EM>automatically</EM> released when the server is done with -them. -</P> -<P> -The way this works is as follows: the memory which is allocated, file -opened, <EM>etc.</EM>, to deal with a particular request are tied to a -<EM>resource pool</EM> which is allocated for the request. The pool -is a data structure which itself tracks the resources in question. -</P> -<P> -When the request has been processed, the pool is <EM>cleared</EM>. At -that point, all the memory associated with it is released for reuse, -all files associated with it are closed, and any other clean-up -functions which are associated with the pool are run. When this is -over, we can be confident that all the resource tied to the pool have -been released, and that none of them have leaked. -</P> -<P> -Server restarts, and allocation of memory and resources for per-server -configuration, are handled in a similar way. There is a -<EM>configuration pool</EM>, which keeps track of resources which were -allocated while reading the server configuration files, and handling -the commands therein (for instance, the memory that was allocated for -per-server module configuration, log files and other files that were -opened, and so forth). When the server restarts, and has to reread -the configuration files, the configuration pool is cleared, and so the -memory and file descriptors which were taken up by reading them the -last time are made available for reuse. -</P> -<P> -It should be noted that use of the pool machinery isn't generally -obligatory, except for situations like logging handlers, where you -really need to register cleanups to make sure that the log file gets -closed when the server restarts (this is most easily done by using the -function <CODE><A HREF="#pool-files">ap_pfopen</A></CODE>, which also -arranges for the underlying file descriptor to be closed before any -child processes, such as for CGI scripts, are <CODE>exec</CODE>ed), or -in case you are using the timeout machinery (which isn't yet even -documented here). However, there are two benefits to using it: -resources allocated to a pool never leak (even if you allocate a -scratch string, and just forget about it); also, for memory -allocation, <CODE>ap_palloc</CODE> is generally faster than -<CODE>malloc</CODE>. -</P> -<P> -We begin here by describing how memory is allocated to pools, and then -discuss how other resources are tracked by the resource pool -machinery. -</P> -<H3>Allocation of memory in pools</H3> -<P> -Memory is allocated to pools by calling the function -<CODE>ap_palloc</CODE>, which takes two arguments, one being a pointer to -a resource pool structure, and the other being the amount of memory to -allocate (in <CODE>char</CODE>s). Within handlers for handling -requests, the most common way of getting a resource pool structure is -by looking at the <CODE>pool</CODE> slot of the relevant -<CODE>request_rec</CODE>; hence the repeated appearance of the -following idiom in module code: -</P> -<PRE> -int my_handler(request_rec *r) -{ - struct my_structure *foo; - ... - - foo = (foo *)ap_palloc (r->pool, sizeof(my_structure)); -} -</PRE> -<P> -Note that <EM>there is no <CODE>ap_pfree</CODE></EM> --- -<CODE>ap_palloc</CODE>ed memory is freed only when the associated -resource pool is cleared. This means that <CODE>ap_palloc</CODE> does not -have to do as much accounting as <CODE>malloc()</CODE>; all it does in -the typical case is to round up the size, bump a pointer, and do a -range check. -</P> -<P> -(It also raises the possibility that heavy use of <CODE>ap_palloc</CODE> -could cause a server process to grow excessively large. There are -two ways to deal with this, which are dealt with below; briefly, you -can use <CODE>malloc</CODE>, and try to be sure that all of the memory -gets explicitly <CODE>free</CODE>d, or you can allocate a sub-pool of -the main pool, allocate your memory in the sub-pool, and clear it out -periodically. The latter technique is discussed in the section on -sub-pools below, and is used in the directory-indexing code, in order -to avoid excessive storage allocation when listing directories with -thousands of files). -</P> -<H3>Allocating initialized memory</H3> -<P> -There are functions which allocate initialized memory, and are -frequently useful. The function <CODE>ap_pcalloc</CODE> has the same -interface as <CODE>ap_palloc</CODE>, but clears out the memory it -allocates before it returns it.

Both of these routines -arrange for the file to be closed when the resource pool in question -is cleared. -</P> -<P> -Unlike the case for memory, there <EM>are</EM> functions to close -files allocated with <CODE>ap_pfopen</CODE>, and <CODE>ap_popenf</CODE>, -namely <CODE>ap_pfclose</CODE> and <CODE>ap_pclosef</CODE>. (This is -because, on many systems, the number of files which a single process -can have open is quite limited). It is important to use these -functions to close files allocated with <CODE>ap_pfopen</CODE> and -<CODE>ap_popenf</CODE>, since to do otherwise could cause fatal errors on -systems such as Linux, which react badly if the same -<CODE>FILE*</CODE> is closed more than once. -</P> -<P> -(Using the <CODE>close</CODE> functions is not mandatory, since the -file will eventually be closed regardless, but you should consider it -in cases where your module is opening, or could open, a lot of files). -</P> -<H3>Other sorts of resources --- cleanup functions</H3> -<BLOCKQUOTE> -More text goes here. Describe the the cleanup primitives in terms of -which the file stuff is implemented; also, <CODE>spawn_process</CODE>. -</BLOCKQUOTE> -<P> -Pool cleanups live until clear_pool() is called: clear_pool(a) recursively -calls destroy_pool() on all subpools of a; then calls all the cleanups for a; -then releases all the memory for a. destroy_pool(a) calls clear_pool(a) -and then releases the pool structure itself. <EM>i.e.</EM>, clear_pool(a) doesn't -delete a, it just frees up all the resources and you can start using it -again immediately. -</P> -<H3>Fine control --- creating and dealing with sub-pools, with a note -on sub-requests</H3> - -On rare occasions, too-free use of <CODE>ap_palloc()</CODE> and the -associated primitives may result in undesirably profligate resource -allocation. You can deal with such a case by creating a -<EM>sub-pool</EM>, allocating within the sub-pool rather than the main -pool, and clearing or destroying the sub-pool, which releases the -resources which were associated with it. (This really <EM>is</EM> a -rare situation; the only case in which it comes up in the standard -module set is in case of listing directories, and then only with -<EM>very</EM> large directories. Unnecessary use of the primitives -discussed here can hair up your code quite a bit, with very little -gain). <P> - -The primitive for creating a sub-pool is <CODE>ap_make_sub_pool</CODE>, -which takes another pool (the parent pool) as an argument. When the -main pool is cleared, the sub-pool will be destroyed. The sub-pool -may also be cleared or destroyed at any time, by calling the functions -<CODE>ap_clear_pool</CODE> and <CODE>ap_destroy_pool</CODE>, respectively. -(The difference is that <CODE>ap_clear_pool</CODE> frees resources -associated with the pool, while <CODE>ap_destroy_pool</CODE> also -deallocates the pool itself. In the former case, you can allocate new -resources within the pool, and clear it again, and so forth; in the -latter case, it is simply gone). <P> - -One final note --- sub-requests have their own resource pools, which -are sub-pools of the resource pool for the main request. The polite -way to reclaim the resources associated with a sub request which you -have allocated (using the <CODE>ap_sub_req_...</CODE> functions) -is <CODE>ap_destroy_sub_req</CODE>, which frees the resource pool. -Before calling this function, be sure to copy anything that you care -about which might be allocated in the sub-request's resource pool into -someplace a little less volatile (for instance, the filename in its -<CODE>request_rec</CODE> structure). <P> - -(Again, under most circumstances, you shouldn't feel obliged to call -this function; only 2K of memory or so are allocated for a typical sub -request, and it will be freed anyway when the main request pool is -cleared. It is only when you are allocating many, many sub-requests -for a single main request that you should seriously consider the -<CODE>ap_destroy_...</CODE> functions). - -<H2><A NAME="config">Configuration, commands and the like</A></H2> - -One of the design goals for this server was to maintain external -compatibility with the NCSA 1.3 server --- that is, to read the same -configuration files, to process all the directives therein correctly, -and in general to be a drop-in replacement for NCSA. On the other -hand, another design goal was to move as much of the server's -functionality into modules which have as little as possible to do with -the monolithic server core. The only way to reconcile these goals is -to move the handling of most commands from the central server into the -modules. <P> - -However, just giving the modules command tables is not enough to -divorce them completely from the server core. The server has to -remember the commands in order to act on them later. That involves -maintaining data which is private to the modules, and which can be -either per-server, or per-directory. Most things are per-directory, -including in particular access control and authorization information, -but also information on how to determine file types from suffixes, -which can be modified by <CODE>AddType</CODE> and -<CODE>DefaultType</CODE> directives, and so forth. In general, the -governing philosophy is that anything which <EM>can</EM> be made -configurable by directory should be; per-server information is -generally used in the standard set of modules for information like -<CODE>Alias</CODE>es and <CODE>Redirect</CODE>s which come into play -before the request is tied to a particular place in the underlying -file system. <P> - -Another requirement for emulating the NCSA server is being able to -handle the per-directory configuration files, generally called -<CODE>.htaccess</CODE> files, though even in the NCSA server they can -contain directives which have nothing at all to do with access -control. Accordingly, after URI -> filename translation, but before -performing any other phase, the server walks down the directory -hierarchy of the underlying filesystem, following the translated -pathname, to read any <CODE>.htaccess</CODE> files which might be -present. The information which is read in then has to be -<EM>merged</EM> with the applicable information from the server's own -config files (either from the <CODE><Directory></CODE> sections -in <CODE>access.conf</CODE>, or from defaults in -<CODE>srm.conf</CODE>, which actually behaves for most purposes almost -exactly like <CODE><Directory /></CODE>).<P> - -Finally, after having served a request which involved reading -<CODE>.htaccess</CODE> files, we need to discard the storage allocated -for handling them. That is solved the same way it is solved wherever -else similar problems come up, by tying those structures to the -per-transaction resource pool. <P> - -<H3><A NAME="per-dir">Per-directory configuration structures</A></H3> - -Let's look out how all of this plays out in <CODE>mod_mime.c</CODE>, -which defines the file typing handler which emulates the NCSA server's -behavior of determining file types from suffixes. What we'll be -looking at, here, is the code which implements the -<CODE>AddType</CODE> and <CODE>AddEncoding</CODE> commands. These -commands can appear in <CODE>.htaccess</CODE> files, so they must be -handled in the module's private per-directory data, which in fact, -consists of two separate <CODE>table</CODE>s for MIME types and -encoding information, and is declared as follows: - -<PRE> -typedef struct { - table *forced_types; /* Additional AddTyped stuff */ - table *encoding_types; /* Added with AddEncoding... */ -} mime_dir_config; -</PRE> - -When the server is reading a configuration file, or -<CODE><Directory></CODE> section, which includes one of the MIME -module's commands, it needs to create a <CODE>mime_dir_config</CODE> -structure, so those commands have something to act on. It does this -by invoking the function it finds in the module's `create per-dir -config slot', with two arguments: the name of the directory to which -this configuration information applies (or <CODE>NULL</CODE> for -<CODE>srm.conf</CODE>), and a pointer to a resource pool in which the -allocation should happen. <P> - -(If we are reading a <CODE>.htaccess</CODE> file, that resource pool -is the per-request resource pool for the request; otherwise it is a -resource pool which is used for configuration data, and cleared on -restarts. Either way, it is important for the structure being created -to vanish when the pool is cleared, by registering a cleanup on the -pool if necessary). <P> - -For the MIME module, the per-dir config creation function just -<CODE>ap_palloc</CODE>s the structure above, and a creates a couple of -<CODE>table</CODE>s to fill it. That looks like this: - -<PRE> -void *create_mime_dir_config (pool *p, char *dummy) -{ - mime_dir_config *new = - (mime_dir_config *) ap_palloc (p, sizeof(mime_dir_config)); - - new->forced_types = ap_make_table (p, 4); - new->encoding_types = ap_make_table (p, 4); - - return new; -} -</PRE> - -Now, suppose we've just read in a <CODE>.htaccess</CODE> file. We -already have the per-directory configuration structure for the next -directory up in the hierarchy. If the <CODE>.htaccess</CODE> file we -just read in didn't have any <CODE>AddType</CODE> or -<CODE>AddEncoding</CODE> commands, its per-directory config structure -for the MIME module is still valid, and we can just use it. -Otherwise, we need to merge the two structures somehow. <P> - -To do that, the server invokes the module's per-directory config merge -function, if one is present. That function takes three arguments: -the two structures being merged, and a resource pool in which to -allocate the result. For the MIME module, all that needs to be done -is overlay the tables from the new per-directory config structure with -those from the parent: - -<PRE> -void *merge_mime_dir_configs (pool *p, void *parent_dirv, void *subdirv) -{ - mime_dir_config *parent_dir = (mime_dir_config *)parent_dirv; - mime_dir_config *subdir = (mime_dir_config *)subdirv; - mime_dir_config *new = - (mime_dir_config *)ap_palloc (p, sizeof(mime_dir_config)); - - new->forced_types = ap_overlay_tables (p, subdir->forced_types, - parent_dir->forced_types); - new->encoding_types = ap_overlay_tables (p, subdir->encoding_types, - parent_dir->encoding_types); - - return new; -} -</PRE> - -As a note --- if there is no per-directory merge function present, the -server will just use the subdirectory's configuration info, and ignore -the parent's. For some modules, that works just fine (<EM>e.g.</EM>, for the -includes module, whose per-directory configuration information -consists solely of the state of the <CODE>XBITHACK</CODE>), and for -those modules, you can just not declare one, and leave the -corresponding structure slot in the module itself <CODE>NULL</CODE>.<P> - -<H3><A NAME="commands">Command handling</A></H3> - -Now that we have these structures, we need to be able to figure out -how to fill them. That involves processing the actual -<CODE>AddType</CODE> and <CODE>AddEncoding</CODE> commands. To find -commands, the server looks in the module's <CODE>command table</CODE>. -That table contains information on how many arguments the commands -take, and in what formats, where it is permitted, and so forth. That -information is sufficient to allow the server to invoke most -command-handling functions with pre-parsed arguments. Without further -ado, let's look at the <CODE>AddType</CODE> command handler, which -looks like this (the <CODE>AddEncoding</CODE> command looks basically -the same, and won't be shown here): - -<PRE> -char *add_type(cmd_parms *cmd, mime_dir_config *m, char *ct, char *ext) -{ - if (*ext == '.') ++ext; - ap_table_set (m->forced_types, ext, ct); - return NULL; -} -</PRE> - -This command handler is unusually simple. As you can see, it takes -four arguments, two of which are pre-parsed arguments, the third being -the per-directory configuration structure for the module in question, -and the fourth being a pointer to a <CODE>cmd_parms</CODE> structure. -That structure contains a bunch of arguments which are frequently of -use to some, but not all, commands, including a resource pool (from -which memory can be allocated, and to which cleanups should be tied), -and the (virtual) server being configured, from which the module's -per-server configuration data can be obtained if required.<P> - -Another way in which this particular command handler is unusually -simple is that there are no error conditions which it can encounter. -If there were, it could return an error message instead of -<CODE>NULL</CODE>; this causes an error to be printed out on the -server's <CODE>stderr</CODE>, followed by a quick exit, if it is in -the main config files; for a <CODE>.htaccess</CODE> file, the syntax -error is logged in the server error log (along with an indication of -where it came from), and the request is bounced with a server error -response (HTTP error status, code 500). <P> - -The MIME module's command table has entries for these commands, which -look like this: - -<PRE> -command_rec mime_cmds[] = { -{ "AddType", add_type, NULL, OR_FILEINFO, TAKE2, - "a mime type followed by a file extension" }, -{ "AddEncoding", add_encoding, NULL, OR_FILEINFO, TAKE2, - "an encoding (<EM>e.g.</EM>, gzip), followed by a file extension" }, -{ NULL } -}; -</PRE> - -The entries in these tables are: - -<UL> - <LI> The name of the command - <LI> The function which handles it - <LI> a <CODE>(void *)</CODE> pointer, which is passed in the - <CODE>cmd_parms</CODE> structure to the command handler --- - this is useful in case many similar commands are handled by the - same function. - <LI> A bit mask indicating where the command may appear. There are - mask bits corresponding to each <CODE>AllowOverride</CODE> - option, and an additional mask bit, <CODE>RSRC_CONF</CODE>, - indicating that the command may appear in the server's own - config files, but <EM>not</EM> in any <CODE>.htaccess</CODE> - file. - <LI> A flag indicating how many arguments the command handler wants - pre-parsed, and how they should be passed in. - <CODE>TAKE2</CODE> indicates two pre-parsed arguments. Other - options are <CODE>TAKE1</CODE>, which indicates one pre-parsed - argument, <CODE>FLAG</CODE>, which indicates that the argument - should be <CODE>On</CODE> or <CODE>Off</CODE>, and is passed in - as a boolean flag, <CODE>RAW_ARGS</CODE>, which causes the - server to give the command the raw, unparsed arguments - (everything but the command name itself). There is also - <CODE>ITERATE</CODE>, which means that the handler looks the - same as <CODE>TAKE1</CODE>, but that if multiple arguments are - present, it should be called multiple times, and finally - <CODE>ITERATE2</CODE>, which indicates that the command handler - looks like a <CODE>TAKE2</CODE>, but if more arguments are - present, then it should be called multiple times, holding the - first argument constant. - <LI> Finally, we have a string which describes the arguments that - should be present.

Engelschall <rse@apache.org>, April 1998</ADDRESS> - -</DIV> - -<H3>Background</H3> - -<P>On modern Unix derivatives there exists a nifty mechanism usually called -dynamic linking/loading of <EM>Dynamic Shared Objects</EM> (DSO) which -provides a way to build a piece of program code in a special format for -loading it at run-time into the address space of an executable program. - -<P>This loading can usually be done in two ways: Automatically by a system -program called <CODE>ld.so</CODE> when an executable program is started or -manually from within the executing program via a programmatic system interface -to the Unix loader through the system calls <CODE>dlopen()/dlsym()</CODE>. - -<P>In the first way the DSO's are usually called <EM>shared libraries</EM> or -<EM>DSO libraries</EM> and named <CODE>libfoo.so</CODE> or -<CODE>libfoo.so.1.2</CODE>. They reside in a system directory (usually -<CODE>/usr/lib</CODE>) and the link to the executable program is established -at build-time by specifying <CODE>-lfoo</CODE> to the linker command. This -hard-codes library references into the executable program file so that at -start-time the Unix loader is able to locate <CODE>libfoo.so</CODE> in -<CODE>/usr/lib</CODE>, in paths hard-coded via linker-options like -<CODE>-R</CODE> or in paths configured via the environment variable -<CODE>LD_LIBRARY_PATH</CODE>. It then resolves any (yet unresolved) symbols in -the executable program which are available in the DSO. - -<P>Symbols in the executable program are usually not referenced by the DSO -(because it's a reusable library of general code) and hence no further -resolving has to be done. The executable program has no need to do anything on -its own to use the symbols from the DSO because the complete resolving is done -by the Unix loader. (In fact, the code to invoke <CODE>ld.so</CODE> is part of -the run-time startup code which is linked into every executable program which -has been bound non-static). The advantage of dynamic loading of common library -code is obvious: the library code needs to be stored only once, in a system -library like <CODE>libc.so</CODE>, saving disk space for every program. - -<P>In the second way the DSO's are usually called <EM>shared objects</EM> or -<EM>DSO files</EM> and can be named with an arbitrary extension (although the -canonical name is <CODE>foo.so</CODE>). These files usually stay inside a -program-specific directory and there is no automatically established link to -the executable program where they are used. Instead the executable program -manually loads the DSO at run-time into its address space via -<CODE>dlopen()</CODE>. At this time no resolving of symbols from the DSO for -the executable program is done. But instead the Unix loader automatically -resolves any (yet unresolved) symbols in the DSO from the set of symbols -exported by the executable program and its already loaded DSO libraries -(especially all symbols from the ubiquitous <CODE>libc.so</CODE>). This way -the DSO gets knowledge of the executable program's symbol set as if it had -been statically linked with it in the first place. - -<P>Finally, to take advantage of the DSO's API the executable program has to -resolve particular symbols from the DSO via <CODE>dlsym()</CODE> for later use -inside dispatch tables <EM>etc.</EM> In other words: The executable program has to -manually resolve every symbol it needs to be able to use it. The advantage of -such a mechanism is that optional program parts need not be loaded (and thus -do not spend memory) until they are needed by the program in question. When -required, these program parts can be loaded dynamically to extend the base -program's functionality. - -<P>Although this DSO mechanism sounds straightforward there is at least one -difficult step here: The resolving of symbols from the executable program for -the DSO when using a DSO to extend a program (the second way). Why? Because -"reverse resolving" DSO symbols from the executable program's symbol set is -against the library design (where the library has no knowledge about the -programs it is used by) and is neither available under all platforms nor -standardized. In practice the executable program's global symbols are often -not re-exported and thus not available for use in a DSO. Finding a way to -force the linker to export all global symbols is the main problem one has to -solve when using DSO for extending a program at run-time. - -<H3>Practical Usage</H3> - -<P>The shared library approach is the typical one, because it is what the DSO -mechanism was designed for, hence it is used for nearly all types of libraries -the operating system provides. On the other hand using shared objects for -extending a program is not used by a lot of programs. - -<P>As of 1998 there are only a few software packages available which use the -DSO mechanism to actually extend their functionality at run-time: Perl 5 (via -its XS mechanism and the DynaLoader module), Netscape Server, <EM>etc.</EM> Starting -with version 1.3, Apache joined the crew, because Apache already uses a module -concept to extend its functionality and internally uses a dispatch-list-based -approach to link external modules into the Apache core functionality. So, -Apache is really predestined for using DSO to load its modules at run-time. - -<P>As of Apache 1.3, the configuration system supports two optional features -for taking advantage of the modular DSO approach: compilation of the Apache -core program into a DSO library for shared usage and compilation of the -Apache modules into DSO files for explicit loading at run-time. - -<H3>Implementation</H3> - -<P>The DSO support for loading individual Apache modules is based on a module -named <A HREF="mod/mod_so.html"><CODE>mod_so.c</CODE></A> which has to be -statically compiled into the Apache core. It is the only module besides -<CODE>http_core.c</CODE> which cannot be put into a DSO itself -(bootstrapping!). Practically all other distributed Apache modules then can -then be placed into a DSO by individually enabling the DSO build for them via -<CODE>configure</CODE>'s <CODE>--enable-shared</CODE> option (see top-level -<CODE>INSTALL</CODE> file) or by changing the <CODE>AddModule</CODE> command -in your <CODE>src/Configuration</CODE> into a <CODE>SharedModule</CODE> -command (see <CODE>src/INSTALL</CODE> file). After a module is compiled into -a DSO named <CODE>mod_foo.so</CODE> you can use <A -HREF="mod/mod_so.html"><CODE>mod_so</CODE></A>'s <A -HREF="mod/mod_so.html#loadmodule"><CODE>LoadModule</CODE></A> command in your -<CODE>httpd.conf</CODE> file to load this module at server startup or restart. - -<P>To simplify this creation of DSO files for Apache modules (especially for -third-party modules) a new support program named <CODE>apxs</CODE> (<EM>APache -eXtenSion</EM>) is available. It can be used to build DSO based modules -<EM>outside of</EM> the Apache source tree. The idea is simple: When -installing Apache the <CODE>configure</CODE>'s <CODE>make install</CODE> -procedure installs the Apache C header files and puts the platform-dependent -compiler and linker flags for building DSO files into the <CODE>apxs</CODE> -program. This way the user can use <CODE>apxs</CODE> to compile his Apache -module sources without the Apache distribution source tree and without having -to fiddle with the platform-dependent compiler and linker flags for DSO -support. - -<P>To place the complete Apache core program into a DSO library (only required -on some of the supported platforms to force the linker to export the apache -core symbols -- a prerequisite for the DSO modularization) the rule -<CODE>SHARED_CORE</CODE> has to be enabled via <CODE>configure</CODE>'s -<CODE>--enable-rule=SHARED_CORE</CODE> option (see top-level -<CODE>INSTALL</CODE> file) or by changing the <CODE>Rule</CODE> command in -your <CODE>Configuration</CODE> file to <CODE>Rule SHARED_CORE=yes</CODE> (see -<CODE>src/INSTALL</CODE> file). The Apache core code is then placed into a DSO -library named <CODE>libhttpd.so</CODE>. Because one cannot link a DSO against -static libraries on all platforms, an additional executable program named -<CODE>libhttpd.ep</CODE> is created which both binds this static code and -provides a stub for the <CODE>main()</CODE> function. Finally the -<CODE>httpd</CODE> executable program itself is replaced by a bootstrapping -code which automatically makes sure the Unix loader is able to load and start -<CODE>libhttpd.ep</CODE> by providing the <CODE>LD_LIBRARY_PATH</CODE> to -<CODE>libhttpd.so</CODE>. - -<H3>Supported Platforms</H3> - -<P>Apache's <CODE>src/Configure</CODE> script currently has only limited but -adequate built-in knowledge on how to compile DSO files, because as already -mentioned this is heavily platform-dependent.

This is at least a great benefit for vendor package - maintainers who can create a Apache core package and additional packages - containing extensions like PHP3, mod_perl, mod_fastcgi, <EM>etc.</EM> -<P> -<LI> Easier Apache module prototyping because with the DSO/<CODE>apxs</CODE> - pair you can both work outside the Apache source tree and only need an - <CODE>apxs -i</CODE> command followed by an <CODE>apachectl - restart</CODE> to bring a new version of your currently developed module - into the running Apache server. -</UL> - -<P>DSO has the following disadvantages: - -<UL> -<LI> The DSO mechanism cannot be used on every platform because not all - operating systems support dynamic loading of code into the address space - of a program. -<P> -<LI> The server is approximately 20% slower at startup time because of the - symbol resolving overhead the Unix loader now has to do. -<P> -<LI> The server is approximately 5% slower at execution time under some - platforms because position independent code (PIC) sometimes needs - complicated assembler tricks for relative addressing which are not - necessarily as fast as absolute addressing. -<P> -<LI> Because DSO modules cannot be linked against other DSO-based libraries - (<CODE>ld -lfoo</CODE>) on all platforms (for instance a.out-based - platforms usually don't provide this functionality while ELF-based - platforms do) you cannot use the DSO mechanism for all types of modules. - Or in other words, modules compiled as DSO files are restricted to only - use symbols from the Apache core, from the C library (<CODE>libc</CODE>) - and all other dynamic or static libraries used by the Apache core, or - from static library archives (<CODE>libfoo.a</CODE>) containing position - independent code. The only chances to use other code is to either make - sure the Apache core itself already contains a reference to it, loading - the code yourself via <CODE>dlopen()</CODE> or enabling the - <CODE>SHARED_CHAIN</CODE> rule while building Apache when your platform - supports linking DSO files against DSO libraries. -<P> -<LI> Under some platforms (many SVR4 systems) there is no way to force the - linker to export all global symbols for use in DSO's when linking the - Apache httpd executable program.

There are - additional tunable parameters included here, to be used - cautiously by an informed system administrator. - -TUNING - - To tune the web server, the number of simultaneous socket - connection requests are limited by: - - somaxconn Sets the maximum number of pending requests - allowed to wait on a listening socket. The - default value in Digital UNIX V3.2 is 8. - This patch kit increases the default to 1024, - which matches the value in Digital UNIX V4.0. - - sominconn Sets the minimum number of pending connections - allowed on a listening socket. When a user - process calls listen with a backlog less - than sominconn, the backlog will be set to - sominconn. sominconn overrides somaxconn. - The default value is 1. - - The effectiveness of tuning these parameters can be monitored by - the sobacklog variables available in the kernel: - - sobacklog_hiwat Tracks the maximum pending requests to any - socket. The initial value is 0. - - sobacklog_drops Tracks the number of drops exceeding the - socket set backlog limit. The initial - value is 0. - - somaxconn_drops Tracks the number of drops exceeding the - somaxconn limit. When sominconn is larger - than somaxconn, tracks the number of drops - exceeding sominconn. The initial value is 0. - - TCP timer parameters also affect performance. Tuning the following - require some knowledge of the characteristics of the network. - - tcp_msl Sets the tcp maximum segment lifetime. - This is the maximum lifetime in half - seconds that a packet can be in transit - on the network. This value, when doubled, - is the length of time a connection remains - in the TIME_WAIT state after a incoming - close request is processed. The unit is - specified in 1/2 seconds, the initial - value is 60. - - tcp_rexmit_interval_min - Sets the minimum TCP retransmit interval. - For some WAN networks the default value may - be too short, causing unnecessary duplicate - packets to be sent. The unit is specified - in 1/2 seconds, the initial value is 1. - - tcp_keepinit This is the amount of time a partially - established connection will sit on the listen - queue before timing out (<EM>e.g.</EM>, if a client - sends a SYN but never answers our SYN/ACK). - Partially established connections tie up slots - on the listen queue. If the queue starts to - fill with connections in SYN_RCVD state, - tcp_keepinit can be decreased to make those - partial connects time out sooner. This should - be used with caution, since there might be - legitimate clients that are taking a while - to respond to SYN/ACK. The unit is specified - in 1/2 seconds, the default value is 150 - (ie. 75 seconds). - - The hashlist size for the TCP inpcb lookup table is regulated by: - - tcbhashsize The number of hash buckets used for the - TCP connection table used in the kernel. - The initial value is 32. For best results, - should be specified as a power of 2. For - busy Web servers, set this to 2048 or more. - - The hashlist size for the interface alias table is regulated by: - - inifaddr_hsize The number of hash buckets used for the - interface alias table used in the kernel. - The initial value is 32. For best results, - should be specified as a power of 2. - - ipport_userreserved The maximum number of concurrent non-reserved, - dynamically allocated ports. Default range - is 1025-5000. The maximum value is 65535. - This limits the numer of times you can - simultaneously telnet or ftp out to connect - to other systems. - - tcpnodelack Don't delay acknowledging TCP data; this - can sometimes improve performance of locally - run CAD packages.

See the <A HREF="./">Apache documentation</A> for all the -available directives. - -<P> - -The main differences in Apache for Windows are: - -<UL> - <LI><P>Because Apache for Windows is multithreaded, it does not use a - separate process for each request, as Apache does with - Unix. Instead there are usually only two Apache processes running: - a parent process, and a child which handles the requests. Within - the child each request is handled by a separate thread. - <P> - - So the "process"-management directives are different: - <P><A - HREF="mod/core.html#maxrequestsperchild">MaxRequestsPerChild</A> - - Like the Unix directive, this controls how many requests a - process will serve before exiting. However, unlike Unix, a - process serves all the requests at once, not just one, so if - this is set, it is recommended that a very high number is - used. The recommended default, <CODE>MaxRequestsPerChild - 0</CODE>, does not cause the process to ever exit. - <P><A HREF="mod/core.html#threadsperchild">ThreadsPerChild</A> - - This directive is new, and tells the server how many threads it - should use. This is the maximum number of connections the server - can handle at once; be sure and set this number high enough for - your site if you get a lot of hits. The recommended default is - <CODE>ThreadsPerChild 50</CODE>.</P> - <LI><P>The directives that accept filenames as arguments now must use - Windows filenames instead of Unix ones. However, because Apache - uses Unix-style names internally, you must use forward slashes, not - backslashes. Drive letters can be used; if omitted, the drive with - the Apache executable will be assumed.</P> - <LI><P>Apache for Windows contains the ability to load modules at runtime, - without recompiling the server. If Apache is compiled normally, it - will install a number of optional modules in the - <CODE>\Apache\modules</CODE> directory. To activate these, or other - modules, the new <A HREF="mod/mod_so.html#loadmodule">LoadModule</A> - directive must be used. For example, to active the status module, - use the following (in addition to the status-activating directives - in <CODE>access.conf</CODE>):</P> -<PRE> - LoadModule status_module modules/ApacheModuleStatus.dll -</PRE> - <P>Information on <A HREF="mod/mod_so.html#creating">creating loadable - modules</A> is also available.</P> - <LI><P>Apache can also load ISAPI Extensions (<EM>i.e.</EM>, Internet Server - Applications), such as those used by Microsoft's IIS, and other - Windows servers. <A HREF="mod/mod_isapi.html">More information - is available.</A> -</UL> - -<H2><A NAME="service">Running Apache for Windows as a Service</A></H2> - <STRONG>Note: The -n option to specify a service name is only available - with Apache 1.3.7 and later.

To make this work, -all that is needed is to make sure that the names -<SAMP>www.domain.tld</SAMP> and <SAMP>www.otherdomain.tld</SAMP> -are pointing to the IP address <SAMP>111.22.33.44</SAMP></P> - -<P>Note: When you specify an IP address in a <CODE>NameVirtualHost</CODE> -directive then requests to that IP address will only ever be served -by matching <VirtualHost>s. The "main server" will -<STRONG>never</STRONG> be served from the specified IP address. -If you start to use virtual hosts you should stop to use the "main server" -as an independent server and rather use it as a place for -configuration directives that are common for all your virtual hosts. -In other words, you should add a <VirtualHost> section for -<EM>every</EM> server (hostname) you want to maintain on your server. - -<P>Additionally, many servers may wish to be accessible by more than -one name. For example, the example server might want to be accessible -as <CODE>domain.tld</CODE>, or <CODE>www2.domain.tld</CODE>, assuming -the IP addresses pointed to the same server. In fact, one might want it -so that all addresses at <CODE>domain.tld</CODE> were picked up by the -server. This is possible with the -<A HREF="../mod/core.html#serveralias"><CODE>ServerAlias</CODE></A> -directive, placed inside the <VirtualHost> section. For -example:</P> - -<PRE> - ServerAlias domain.tld *.domain.tld -</PRE> - -<P>Note that you can use <CODE>*</CODE> and <CODE>?</CODE> as wild-card -characters.</P> - -<P>You also might need <CODE>ServerAlias</CODE> if you are -serving local users who do not always include the domain name. -For example, if local users are -familiar with typing "www" or "www.foobar" then you will need to add -<CODE>ServerAlias www www.foobar</CODE>. It isn't possible for the -server to know what domain the client uses for their name resolution -because the client doesn't provide that information in the request. -The <CODE>ServerAlias</CODE> directive is generally a way to have different -hostnames pointing to the same virtual host. -</P> - -<H2>Compatibility with Older Browsers</H2> - -<P>As mentioned earlier, there are still some clients in use who -do not send the required data for the name-based virtual hosts to work -properly. These clients will always be sent the pages from the -first virtual host listed for that IP address (the -<CITE>primary</CITE> name-based virtual host).</P> - -<P>There is a possible workaround with the -<A HREF="../mod/core.html#serverpath"><CODE>ServerPath</CODE></A> -directive, albeit a slightly cumbersome one:</P> - -<P>Example configuration: - -<PRE> - NameVirtualHost 111.22.33.44 - - <VirtualHost 111.22.33.44> - ServerName www.domain.tld - ServerPath /domain - DocumentRoot /web/domain - </VirtualHost> -</PRE> - -<P>What does this mean? It means that a request for any URI beginning -with "<SAMP>/domain</SAMP>" will be served from the virtual host -<SAMP>www.domain.tld</SAMP> This means that the pages can be accessed as -<CODE>http://www.domain.tld/domain/</CODE> for all clients, although -clients sending a <SAMP>Host:</SAMP> header can also access it as -<CODE>http://www.domain.tld/</CODE>.</P> - -<P>In order to make this work, put a link on your primary virtual host's page -to <SAMP>http://www.domain.tld/domain/</SAMP> -Then, in the virtual host's pages, be sure to use either purely -relative links (<EM>e.g.</EM>, "<SAMP>file.html</SAMP>" or -"<SAMP>../icons/image.gif</SAMP>" or links containing the prefacing -<SAMP>/domain/</SAMP> -(<EM>e.g.</EM>, "<SAMP>http://www.domain.tld/domain/misc/file.html</SAMP>" or -"<SAMP>/domain/misc/file.html</SAMP>").</P> - -<P>This requires a bit of -discipline, but adherence to these guidelines will, for the most part, -ensure that your pages will work with all browsers, new and old.</P> - -<P>See also: <A HREF="examples.html#serverpath">ServerPath configuration -example</A></P> - -<!--#include virtual="footer.html" --> -</BODY> -</HTML> diff --git a/emacs-style b/emacs-style deleted file mode 100644 index 283b6f0255..0000000000 --- a/emacs-style +++ /dev/null @@ -1,10 +0,0 @@ -(add-hook 'c-mode-hook - (function (lambda () - (c-set-offset 'inclass' ++) - (c-set-offset 'defun-block-intro' ++) - (c-set-offset 'statement-block-intro' ++) - (c-set-offset 'substatement' ++) - (c-set-offset 'brace-list-intro' ++) - (c-set-offset 'statement-case-intro' ++) - ))) -(setq c++-mode-hook c-mode-hook) diff --git a/httpd.dsp b/httpd.dsp deleted file mode 100644 index 2247eeb72f..0000000000 --- a/httpd.dsp +++ /dev/null @@ -1,413 +0,0 @@ -# Microsoft Developer Studio Project File - Name="ApacheCore" - Package Owner=<4> -# Microsoft Developer Studio Generated Build File, Format Version 5.00 -# ** DO NOT EDIT ** - -# TARGTYPE "Win32 (x86) Dynamic-Link Library" 0x0102 - -CFG=ApacheCore - Win32 Release -!MESSAGE This is not a valid makefile.

Note that access to the counters is - * not synchronized because they are just indicaters, and whether they are - * off by a few doesn't matter; and for the same reason no attempt is made - * to guarantee the num_renewed is correct in the face of clients spoofing - * the opaque field. - */ - -/* - * Get the client given its client number (the key).

Each request will be logged to _ALL_ the - * named files, in the appropriate format. - * - * If no TransferLog or CustomLog directive appears in a VirtualHost, - * the request will be logged to the log file(s) defined outside - * the virtual host section. If a TransferLog or CustomLog directive - * appears in the VirtualHost section, the log files defined outside - * the VirtualHost will _not_ be used. This makes this module compatable - * with the CLF and config log modules, where the use of TransferLog - * inside the VirtualHost section overrides its use outside. - * - * Examples: - * - * TransferLog logs/access_log - * <VirtualHost> - * LogFormat "... custom format ..." - * TransferLog log/virtual_only - * CustomLog log/virtual_useragents "%t %{user-agent}i" - * </VirtualHost> - * - * This will log using CLF to access_log any requests handled by the - * main server, while any requests to the virtual host will be logged - * with the "... custom format..." to virtual_only _AND_ using - * the custom user-agent log to virtual_useragents. - * - * Note that the NCSA referer and user-agent logs are easily added with - * CustomLog: - * CustomLog logs/referer "%{referer}i -> %U" - * CustomLog logs/agent "%{user-agent}i" - * - * RefererIgnore functionality can be obtained with conditional - * logging (SetEnvIf and CustomLog ... env=!VAR). - * - * But using this method allows much easier modification of the - * log format, e.g. to log hosts along with UA: - * CustomLog logs/referer "%{referer}i %U %h" - * - * The argument to LogFormat and CustomLog is a string, which can include - * literal characters copied into the log files, and '%' directives as - * follows: - * - * %...b: bytes sent, excluding HTTP headers. - * %...{FOOBAR}e: The contents of the environment variable FOOBAR - * %...f: filename - * %...h: remote host - * %...a: remote IP-address - * %...A: local IP-address - * %...{Foobar}i: The contents of Foobar: header line(s) in the request - * sent to the client. - * %...l: remote logname (from identd, if supplied) - * %...{Foobar}n: The contents of note "Foobar" from another module. - * %...{Foobar}o: The contents of Foobar: header line(s) in the reply. - * %...p: the port the request was served to - * %...P: the process ID of the child that serviced the request. - * %...r: first line of request - * %...s: status.

This means that the - * server functionality can be extended without recompiling and even without - * taking the server down at all. Only a HUP or WINCH signal needs to be send - * to the server to reload the dynamically loaded modules. - * - * To use, you'll first need to build your module as a shared library, then - * update your configuration (httpd.conf) to get the Apache core to load the - * module at start-up. - * - * The easiest way to build a module as a shared library is to use the - * `SharedModule' command in the Configuration file, instead of `AddModule'. - * You should also change the file extension from `.o' to `.so'. So, for - * example, to build the status module as a shared library edit Configuration - * and change - * AddModule modules/standard/mod_status.o - * to - * SharedModule modules/standard/mod_status.so - * - * Run Configure and make. Now Apache's httpd binary will _not_ include - * mod_status. Instead a shared object called mod_status.so will be build, in - * the modules/standard directory. You can build most of the modules as shared - * libraries like this. - * - * To use the shared module, move the .so file(s) into an appropriate - * directory. You might like to create a directory called "modules" under you - * server root for this (e.g. /usr/local/httpd/modules). - * - * Then edit your conf/httpd.conf file, and add LoadModule lines. For - * example - * LoadModule status_module modules/mod_status.so - * - * The first argument is the module's structure name (look at the end of the - * module source to find this). The second option is the path to the module - * file, relative to the server root. Put these directives right at the top - * of your httpd.conf file. - * - * Now you can start Apache. A message will be logged at "debug" level to your - * error_log to confirm that the module(s) are loaded (use "LogLevel debug" - * directive to get these log messages). - * - * If you edit the LoadModule directives while the server is live you can get - * Apache to re-load the modules by sending it a HUP or WINCH signal as normal. - * You can use this to dynamically change the capability of your server - * without bringing it down. - * - * Because currently there is only limited builtin support in the Configure - * script for creating the shared library files (`.so'), please consult your - * vendors cc(1), ld(1) and dlopen(3) manpages to find out the appropriate - * compiler and linker flags and insert them manually into the Configuration - * file under CFLAGS_SHLIB, LDFLAGS_SHLIB and LDFLAGS_SHLIB_EXPORT. - * - * If you still have problems figuring out the flags both try the paper - * http://developer.netscape.com/library/documentation/enterprise - * /unix/svrplug.htm#1013807 - * or install a Perl 5 interpreter on your platform and then run the command - * - * $ perl -V:usedl -V:ccdlflags -V:cccdlflags -V:lddlflags - * - * This gives you what type of dynamic loading Perl 5 uses on your platform - * and which compiler and linker flags Perl 5 uses to create the shared object - * files. - * - * Another location where you can find useful hints is the `ltconfig' script - * of the GNU libtool 1.2 package. Search for your platform name inside the - * various "case" constructs. - * - */ - - -#define CORE_PRIVATE -#include "httpd.h" -#include "http_config.h" -#include "http_log.h" -#include "ap_config.h" - -module MODULE_VAR_EXPORT so_module; - - -/* - * Server configuration to keep track of actually - * loaded modules and the corresponding module name. - */ - -typedef struct moduleinfo { - char *name; - module *modp; -} moduleinfo; - -typedef struct so_server_conf { - ap_array_header_t *loaded_modules; -} so_server_conf; - -static void *so_sconf_create(ap_context_t *p, server_rec *s) -{ - so_server_conf *soc; - - soc = (so_server_conf *)ap_pcalloc(p, sizeof(so_server_conf)); - soc->loaded_modules = ap_make_array(p, DYNAMIC_MODULE_LIMIT, - sizeof(moduleinfo)); -#ifndef NO_DLOPEN - ap_os_dso_init(); -#endif - - return (void *)soc; -} - -#ifndef NO_DLOPEN - -/* - * This is the cleanup for a loaded shared object.

Previous versions of the module defined behaviour - * on a per-server basis. The upshot is that you'll need to revisit your - * configuration files in order to make use of the new module. - * *** - * - * Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP - * headers that can be output in addition to the normal range of - * headers for each file accessed. They appear rather like the Apache - * .asis files, and are able to provide a crude way of influencing - * the Expires: header, as well as providing other curiosities. - * There are many ways to manage meta information, this one was - * chosen because there is already a large number of CERN users - * who can exploit this module. It should be noted that there are probably - * more sensitive ways of managing the Expires: header specifically. - * - * The module obeys the following directives, which can appear - * in the server's .conf files and in .htaccess files. - * - * MetaFiles <on|off> - * - * turns on|off meta file processing for any directory. - * Default value is off - * - * # turn on MetaFiles in this directory - * MetaFiles on - * - * MetaDir <directory name> - * - * specifies the name of the directory in which Apache can find - * meta information files. The directory is usually a 'hidden' - * subdirectory of the directory that contains the file being - * accessed. eg: - * - * # .meta files are in the *same* directory as the - * # file being accessed - * MetaDir . - * - * the default is to look in a '.web' subdirectory. This is the - * same as for CERN 3.+ webservers and behaviour is the same as - * for the directive: - * - * MetaDir .web - * - * MetaSuffix <meta file suffix> - * - * specifies the file name suffix for the file containing the - * meta information. eg: - * - * # our meta files are suffixed with '.cern_meta' - * MetaSuffix .cern_meta - * - * the default is to look for files with the suffix '.meta'. This - * behaviour is the same as for the directive: - * - * MetaSuffix .meta - * - * When accessing the file - * - * DOCUMENT_ROOT/somedir/index.html - * - * this module will look for the file - * - * DOCUMENT_ROOT/somedir/.web/index.html.meta - * - * and will use its contents to generate additional MIME header - * information. - * - * For more information on the CERN Meta file semantics see: - * - * http://www.w3.org/hypertext/WWW/Daemon/User/Config/General.html#MetaDir - * - * Change-log: - * 29.Jan.96 pfopen/pfclose instead of fopen/fclose - * DECLINE when real file not found, we may be checking each - * of the index.html/index.shtml/index.htm variants and don't - * need to report missing ones as spurious errors. - * 31.Jan.96 log_error reports about a malformed .meta file, rather - * than a script error. - * 20.Jun.96 MetaFiles <on|off> default off, added, so that module - * can be configured per-directory.

Essentially "everywhere" should include all possible - * httpds across all servers at a particular "site". We make some assumptions - * that if the site has a cluster of machines then their time is relatively - * synchronized. We also assume that the first address returned by a - * gethostbyname (gethostname()) is unique across all the machines at the - * "site". - * - * We also further assume that pids fit in 32-bits. If something uses more - * than 32-bits, the fix is trivial, but it requires the unrolled uuencoding - * loop to be extended. * A similar fix is needed to support multithreaded - * servers, using a pid/tid combo. - * - * Together, the in_addr and pid are assumed to absolutely uniquely identify - * this one child from all other currently running children on all servers - * (including this physical server if it is running multiple httpds) from each - * other. - * - * The stamp and counter are used to distinguish all hits for a particular - * (in_addr,pid) pair. The stamp is updated using r->request_time, - * saving cpu cycles. The counter is never reset, and is used to permit up to - * 64k requests in a single second by a single child. - * - * The 112-bits of unique_id_rec are encoded using the alphabet - * [A-Za-z0-9@-], resulting in 19 bytes of printable characters. That is then - * stuffed into the environment variable UNIQUE_ID so that it is available to - * other modules. The alphabet choice differs from normal base64 encoding - * [A-Za-z0-9+/] because + and / are special characters in URLs and we want to - * make it easy to use UNIQUE_ID in URLs. - * - * Note that UNIQUE_ID should be considered an opaque token by other - * applications. No attempt should be made to dissect its internal components. - * It is an abstraction that may change in the future as the needs of this - * module change. - * - * It is highly desirable that identifiers exist for "eternity". But future - * needs (such as much faster webservers, moving to 64-bit pids, or moving to a - * multithreaded server) may dictate a need to change the contents of - * unique_id_rec. Such a future implementation should ensure that the first - * field is still a time_t stamp. By doing that, it is possible for a site to - * have a "flag second" in which they stop all of their old-format servers, - * wait one entire second, and then start all of their new-servers. This - * procedure will ensure that the new space of identifiers is completely unique - * from the old space. (Since the first four unencoded bytes always differ.) - */ -/* - * Sun Jun 7 05:43:49 CEST 1998 -- Alvaro - * More comments: - * 1) The UUencoding prodecure is now done in a general way, avoiding the problems - * with sizes and paddings that can arise depending on the architecture. Now the - * offsets and sizes of the elements of the unique_id_rec structure are calculated - * in unique_id_global_init; and then used to duplicate the structure without the - * paddings that might exist. The multithreaded server fix should be now very easy: - * just add a new "tid" field to the unique_id_rec structure, and increase by one - * UNIQUE_ID_REC_MAX. - * 2) unique_id_rec.stamp has been changed from "time_t" to "unsigned int", because - * its size is 64bits on some platforms (linux/alpha), and this caused problems with - * htonl/ntohl.

One "main" - * thread listens for new requests. When something becomes - * available, it does a select and places the newly available socket - * onto a list of "jobs" (add_job()). Then any one of a fixed number - * of "worker" threads takes the top job off the job list with - * remove_job() and handles that connection to completion. After - * the connection has finished the thread is free to take another - * job from the job list. - * - * In the code, the "main" thread is running within the child_main() - * function. The first thing this function does is create the - * worker threads, which operate in the child_sub_main() function. The - * main thread then goes into a loop within child_main() where they - * do a select() on the listening sockets. The select times out once - * per second so that the thread can check for an "exit" signal - * from the parent process (see below). If this signal is set, the - * thread can exit, but only after it has accepted all incoming - * connections already in the listen queue (since Win32 appears - * to through away listened but unaccepted connections when a - * process dies). - * - * Because the main and worker threads exist within a single process - * they are vulnerable to crashes or memory leaks (crashes can also - * be caused within modules, of course). There also needs to be a - * mechanism to perform restarts and shutdowns. This is done by - * creating the main & worker threads within a subprocess. A - * main process (the "parent process") creates one (or more) - * processes to do the work, then the parent sits around waiting - * for the working process to die, in which case it starts a new - * one. The parent process also handles restarts (by creating - * a new working process then signalling the previous working process - * exit ) and shutdowns (by signalling the working process to exit). - * The parent process operates within the master_main() function. This - * process also handles requests from the service manager (NT only). - * - * Signalling between the parent and working process uses a Win32 - * event. Each child has a unique name for the event, which is - * passed to it with the -Z argument when the child is spawned. The - * parent sets (signals) this event to tell the child to die. - * At present all children do a graceful die - they finish all - * current jobs _and_ empty the listen queue before they exit. - * A non-graceful die would need a second event. The -Z argument in - * the child is also used to create the shutdown and restart events, - * since the prefix (apPID) contains the parent process PID. - * - * The code below starts with functions at the lowest level - - * worker threads, and works up to the top level - the main() - * function of the parent process. - * - * The scoreboard (in process memory) contains details of the worker - * threads (within the active working process). There is no shared - * "scoreboard" between processes, since only one is ever active - * at once (or at most, two, when one has been told to shutdown but - * is processes outstanding requests, and a new one has been started). - * This is controlled by a "start_mutex" which ensures only one working - * process is active at once. - **********************************************************************/ - - -/* - * Definition of jobs, shared by main and worker threads. - */ - -typedef struct joblist_s { - struct joblist_s *next; - int sock; -} joblist; - -/* - * Globals common to main and worker threads.
