In a procedural context, such as scripts and CGI-type situations, you can improve the load times and memory usage by loading a module at run-time, only once you are sure you will need it. In the other common load profile for perl applications, the application will start up and then fork off various worker processes. To take full advantage of memory copy-on-write features, the application should load as many modules as possible before forking to prevent them consuming memory in multiple worker processes. Unfortunately, the strategies used to optimise for these two load profiles are diametrically opposed. What improves a situation for one tends to make life worse for the other. DESCRIPTION The "prefork" pragma is intended to allow module writers to optimise module loading for both scenarios with as little additional code as possible. prefork.pm is intended to serve as a central and optional marshalling point for state detection (are we running in compile-time or run-time mode) and to act as a relatively light-weight module loader. Loaders and Forkers "prefork" is intended to be used in two different ways. The first is by a module that wants to indicate that another module should be loaded before forking. This is known as a "Loader". The other is a script or module that will be initiating the forking. It will tell prefork.pm that it is either going to fork, or is about to fork, or for some other reason all modules previously mentioned by the Loaders should be loaded immediately. Usage as a Pragma A Loader can register a module to be loaded using the following use prefork 'My::Module'; The same thing can be done in such a way as to not require prefork being installed, but taking advantage of it if it is. eval "use prefork 'My::Module';"; A Forker can indicate that it will be forking with the following use prefork ':enable'; In any use of "prefork" as a pragma, you can only pass a single value as argument. Any additional arguments will be ignored. (This may throw an error in future versions). Compatbility with mod_perl and others Part of the design of "prefork", and its minimalistic nature, is that it is intended to work easily with existing modules, needing only small changes. For example, "prefork" itself will detect the $ENV{MOD_PERL} environment variable and automatically start in forking mode. prefork has support for integrating with third-party modules, such as Class::Autouse. The "notify" function allows these run-time loaders to register callbacks, to be called once prefork enters forking mode. The synopsis entry above describes adding support for prefork.pm as a dependency. To allow your third-party module loader without a dependency and only if it is installed use the following: eval { require prefork; } prefork::notify( \&function ) unless $@; Using prefork.pm From the Loader side, it is fairly simple. prefork becomes a dependency for your module, and you use it as a pragma as documented above. For the Forker, you have two options. Use as a dependency or optional use. In the dependency case, you add prefork as a dependency and use it as a pragma with the ':enable' option. To add only optional support for prefork, without requiring it to be installed, you should wait until the moment just before you fork and then call "prefork::enable" directly ONLY if it is loaded. # Load modules if any use the prefork pragma. prefork::enable() if $INC{prefork.pm}; This will cause the modules to be loaded ONLY if there are any modules that need to be loaded. The main advantage of the dependency version is that you only need to enable the module once, and not before each fork. If you wish to have your own module leverage off the forking-detection that prefork provides, you can also do the following. use prefork; if ( $prefork::FORKING ) { # Complete some preparation task } Modules that are prefork-aware mod_perl/mod_perl2 Class::Autouse FUNCTIONS prefork $module The 'prefork' function indicates that a module should be loaded before the process will fork. If already in forking mode the module will be loaded immediately. Otherwise it will be added to a queue to be loaded later if it recieves instructions that it is going to be forking. Returns true on success, or dies on error. enable The "enable" function indicates to the prefork module that the process is going to fork, possibly immediately. When called, prefork.pm will immediately load all outstanding modules, and will set a flag so that any further 'prefork' calls will load the module at that time. Returns true, dieing as normal is there is a problem loading a module. notify &function The "notify" function is used to integrate support for modules other than prefork.pm itself. A module loader calls the notify function, passing it a reference to a "CODE" reference (either anon or a function reference). "prefork" will store this CODE reference, and execute it immediately as soon as it knows it is in forking-mode, but after it loads its own modules. Callbacks are called in the order they are registered. Normally, this will happen as soon as the "enable" function is called. However, you should be aware that if prefork is already in preforking mode at the time that the notify function is called, prefork.pm will execute the function immediately. This means that any third party module loader should be fully loaded and initialised before the callback is provided to "notify". Returns true if the function is stored, or dies if not passed a "CODE" reference, or the callback is already set in the notify queue.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS ---------------------------------------------------------------------------- The Artistic License Preamble The intent of this document is to state the conditions under which a Package may be copied, such that the Copyright Holder maintains some semblance of artistic control over the development of the package, while giving the users of the package the right to use and distribute the Package in a more-or-less customary fashion, plus the right to make reasonable modifications.

A module loader calls the notify function, passing it a reference to a C reference (either anon or a function reference). C will store this CODE reference, and execute it immediately as soon as it knows it is in forking-mode, but after it loads its own modules. Callbacks are called in the order they are registered. Normally, this will happen as soon as the C function is called. However, you should be aware that if prefork is B in preforking mode at the time that the notify function is called, prefork.pm will execute the function immediately. This means that any third party module loader should be fully loaded and initialised B the callback is provided to C. Returns true if the function is stored, or dies if not passed a C reference, or the callback is already set in the notify queue. =cut sub notify ($) { # Get the CODE ref callback param my $function = shift; my $reftype = Scalar::Util::reftype($function); unless ( $reftype and $reftype eq 'CODE' ) { Carp::croak("prefork::notify was not passed a CODE reference"); } # Call it immediately is already in forking mode if ( $FORKING ) { $function->(); return 1; } # Is it already defined? if ( List::Util::first { Scalar::Util::refaddr($function) == Scalar::Util::refaddr($_) } @NOTIFY ) { Carp::croak("Callback function already registered"); } # Add to the queue push @NOTIFY, $function; 1; } ##################################################################### # Built-in Notifications # Compile CGI functions automatically prefork::notify( sub { CGI->compile() if $INC{'CGI.pm'}; } ); 1; =pod =head1 TO DO - Add checks for more pre-forking situations =head1 SUPPORT Bugs should be always submitted via the CPAN bug tracker, located at L For other issues, or commercial enhancement or support, contact the author. =head1 AUTHOR Adam Kennedy =head1 COPYRIGHT Thank you to Phase N Australia (L) for permitting the open sourcing and release of this distribution.
