564 | +=head1 DESCRIPTION | |
565 | + | |
566 | +This library implements a generic hook interface for Apache which can be used | |
567 | +to loosely couple code through arbitrary hooks. There are two use cases for | |
568 | +this mechanism: | |
569 | + | |
570 | +=over 3 | |
571 | + | |
572 | +=item B<1. Extension and Overrides> | |
573 | + | |
574 | +Inside a specific code section you want to perform a specific function call | |
575 | +for extension reasons. But you want to allow one or more modules to implement | |
576 | +this function by registering hooks. Those hooks are registered on a stack and | |
577 | +can be even configured to have a I<decline> return value. As long as there are | |
578 | +functions which return the decline value the next function on the stack is | |
579 | +tried. When the first function doesn't return the decline value the hook call | |
580 | +stops. | |
581 | + | |
582 | +The original intent of this use case is to provide a flexible extension | |
583 | +mechanism where modules can override functionality. | |
584 | + | |
585 | +=item B<2. Intercommunication> | |
586 | + | |
587 | +Inside a specific code you have a function you want to export. But you first | |
588 | +want to allow other code to override this function. And second you want to | |
589 | +export this function without real object file symbol references. Instead you | |
590 | +want to register the function and let the users call this function by name. | |
591 | + | |
592 | +The original intent of this use case is to allow inter-module communication | |
593 | +without direct symbol references, which are a big I<no-no> for the I<Dynamic | |
594 | +Shared Object> (DSO) situation. | |
595 | + | |
596 | +=back | |
597 | + | |
598 | +And the following design goals existed: | |
599 | + | |
600 | +=over 3 | |
601 | + | |
602 | +=item B<1. Minimum code changes> | |
603 | + | |
604 | +The hook calls should look very similar to the corresponding direct function | |
605 | +call to allow one to easily translate it. And the total amount of changes for | |
606 | +the hook registration, hook configuration and hook usage should be as small as | |
607 | +possible to minimize the total code changes. Additionally a shorthand API | |
608 | +function (ap_hook_use) should be provided which lets one trivially add a hook | |
609 | +by just changing the code at a single location. | |
610 | + | |
611 | +=item B<2. The hook call has to be maximum flexible> | |
612 | + | |
613 | +In order to avoid nasty hacks, maximum flexiblity for the hook calls is | |
614 | +needed, i.e. any function signature (the set of types for the return value and | |
615 | +the arguments) should be supported. And it should be possible to | |
616 | +register always a context (ctx) variable with a function which is passed to | |
617 | +the corresponding function when the hook call is performed. | |
618 | + | |
619 | +=back | |
620 | + | |
621 | +The implementation of this library directly followed these two design goals. | |
622 | + | |
623 | +=head1 USAGE | |
624 | + | |
625 | +Using this hook API is a four-step process: | |
626 | + | |
627 | +=over 3 | |
628 | + | |
629 | +=item B<1. Initialization> | |
630 | + | |
631 | +Initialize or destroy the hook mechanism inside your application program: | |
632 | + | |
633 | + ap_hook_init(); | |
634 | + : | |
635 | + ap_hook_kill(); | |
636 | + | |
637 | +=item B<2. Configuration> | |
638 | + | |
639 | +Configure a particular hook by specifing its name, signature and return type | |
640 | +semantic: | |
641 | + | |
642 | + ap_hook_configure("lookup", AP_HOOK_SIG2(ptr,ptr,ctx), AP_HOOK_DECLINE(NULL)); | |
643 | + ap_hook_configure("setup", AP_HOOK_SIG2(int,ptr,char), AP_HOOK_DECLTMP(FALSE)); | |
644 | + ap_hook_configure("read", AP_HOOK_SIG2(void,ptr), AP_HOOK_TOPMOST); | |
645 | + ap_hook_configure("logit", AP_HOOK_SIG2(void,ptr), AP_HOOK_ALL); | |
646 | + | |
647 | +This configures four hooks: | |
648 | + | |
649 | +A hook named C<lookup> with the signature C<void *lookup(void *, void *)> | |
650 | +(where the second argument is C<NULL> or the private context pointer of the | |
651 | +hook function which can be optionally provided at the registration step | |
652 | +later) and a return code semantic which says: Proceed as long as the | |
653 | +registered lookup functions return C<NULL> or no more registered functions | |
654 | +exists. A call for this hook has to provide 2 argument only (a pointer to the | |
655 | +return variable and the first argument), because the context is | |
656 | +implicitly provided by the hook mechanism. Sample idea: I<The first function | |
657 | +who was successful in looking up a variable provides the value>. | |
658 | + | |
659 | +A hook named C<setup> with the signature C<int setup(void *, char)" and a | |
660 | +return code semantic equal to the one of the C<lookup> hook. But the decline | |
661 | +return value is implemented by a temporay variable of the hook mechanism and | |
662 | +only used for the decline decision. So a call to this hook has to provide 2 | |
663 | +arguments only (the first and second argument, but no address to a return | |
664 | +value). Sample idea: I<Any function can handle the setup and when one | |
665 | +function handled it stops the processing by indicating this with the return | |
666 | +value>. | |
667 | + | |
668 | +A hook named C<read> with the signature C<void read(void *)> and a return code | |
669 | +semantic which says: Only the top most function on the registered function | |
670 | +stack is tried (and independet of a possible return value in non-void | |
671 | +context). A call to this hook has to provide exactly 1 argument (the | |
672 | +single argument to the hook function). Sample idea: I<We want to | |
673 | +use a read function and allow others to override it, but independent how much | |
674 | +registered functions exists, only top most (= last registered) function | |
675 | +overrides and is used>. | |
676 | + | |
677 | +A hook named C<logit> with the signature C<void logit(void *)> and a return | |
678 | +code semantic which says: All registered functions on the hook functioin stack | |
679 | +are tried. Sample idea: I<We pass a FILE pointer to the logging functions and | |
680 | +any function can log whatever it wants>. | |
681 | + | |
682 | +=item B<3. Registration> | |
683 | + | |
684 | +Register the actual functions which should be used by the hook: | |
685 | + | |
686 | + ap_hook_register("lookup", mylookup, mycontext); | |
687 | + ap_hook_register("setup", mysetup); | |
688 | + ap_hook_register("read", myread); | |
689 | + ap_hook_register("logit", mylogit); | |
690 | + | |
691 | +This registers the function C<mylookup()> under the C<lookup> hook with the | |
692 | +private context given by the variable C<mycontext>. And it registers the | |
693 | +function C<mysetup()> under the C<setup> hook without any context. Same for | |
694 | +C<myread> and C<mylogit>. | |
695 | + | |
696 | +=item B<4. Usage> | |
697 | + | |
698 | +Finally use the hooks, i.e. instead of using direct function calls like | |
699 | + | |
700 | + rc = mylookup(a1, a2); | |
701 | + rc = mysetup(a1, a2); | |
702 | + myread(a1); | |
703 | + mylogit(a1); | |
704 | + | |
705 | +you now use: | |
706 | + | |
707 | + ap_hook_call("lookup", &rc, a1, a2); | |
708 | + ap_hook_call("setup", &rc, a1, a2); | |
709 | + ap_hook_call("read", a1); | |
710 | + ap_hook_call("logit", a1); | |
711 | + | |
712 | +which are internally translated to: | |
713 | + | |
714 | + rc = mylookup(a1, a2, mycontext); | |
715 | + rc = mysetup(a1, a2); | |
716 | + myread(a1); | |
717 | + mylogit(a1); | |
718 | + | |
719 | +Notice two things here: First the context (C<mycontext>) for the C<mylookup()> | |
720 | +function is automatically added by the hook mechanism. And it is a different | |
721 | +(and not fixed) context for each registered function, of course. Second, | |
722 | +return values always have to be pushed into variables and a pointer to them | |
723 | +has to be given as the second argument to C<ap_hook_call> (except for | |
724 | +functions which have a void return type, of course). | |
725 | + | |
726 | +BTW, the return value of C<ap_hook_call()> is always C<TRUE> or C<FALSE>. | |
727 | +C<TRUE> when at least one function call was successful (always the case for | |
728 | +C<AP_HOOK_TOPMOST> and C<AP_HOOK_ALL>). C<FALSE> when all functions | |
729 | +returned the decline value or no functions are registered at all. | |
730 | + | |
731 | +=back | |
732 | + | |
733 | +=head1 RESTRICTIONS | |
734 | + | |
735 | +To make the hook implementation efficient and to not bloat up the code too | |
736 | +much a few restrictions have to make: | |
737 | + | |
738 | +=over 3 | |
739 | + | |
740 | +=item 1. | |
741 | + | |
742 | +Only function calls with up to 4 arguments are implemented. When more are | |
743 | +needed you can either extend the hook implementation by using more bits for | |
744 | +the signature configuration or you can do a workaround when the function is | |
745 | +your own one: Put the remaining (N-4-1) arguments into a structure and pass | |
746 | +only a pointer (one argument) as the forth argument. | |
747 | + | |
748 | +=item 2. | |
749 | + | |
750 | +Only the following ANSI C variable types are supported: | |
751 | + | |
752 | + - For the return value: | |
753 | + void (= none), char, int, float, double, ptr (= void *) | |
754 | + - For the arguments: | |
755 | + ctx (= context), char, int, float, double, ptr (= void *) | |
756 | + | |
757 | +This means in theory that 6^5 (=7776) signature combinations are possible. But | |
758 | +because we don't need all of them inside Apache and it would bloat up the code | |
759 | +too dramatically we implement only a subset of those combinations. The | |
760 | +implemented signatures can be specified inside C<ap_hook.c> and the | |
761 | +corresponding code can be automatically generated by running ``C<perl | |
762 | +ap_hook.c>'' (yeah, no joke ;-). So when you need a hook with a different | |
763 | +still not implemented signature you either have to again use a workaround as | |
764 | +above (i.e. use a structure) or just add the signature to the C<ap_hook.c> | |
765 | +file. | |
766 | + | |
767 | +=head1 EXAMPLE | |
768 | + | |
769 | +We want to call `C<ssize_t read(int, void *, size_t)>' through hooks in order | |
770 | +to allow modules to override this call. So, somewhere we have a replacement | |
771 | +function for C<read()> defined (same signature, of course): | |
772 | + | |
773 | + ssize_t my_read(int, void *, size_t); | |
774 | + | |
775 | +We now configure a C<read> hook. Here the C<AP_HOOK_SIGx()> macro defines the | |
776 | +signature of the C<read()>-like callback functions and has to match the | |
777 | +prototype of C<read()>. But we have to replace typedefs with the physical | |
778 | +underlaying ANSI C types. And C<AP_HOOK_DECLINE()> sets the return value of | |
779 | +the read()-like functions which forces the next hook to be called (here -1). | |
780 | +And we register the original C<read()> function as the default hook. | |
781 | + | |
782 | + ap_hook_configure("read", | |
783 | + AP_HOOK_SIG4(int,int,ptr,int), | |
784 | + AP_HOOK_DECLINE(-1)); | |
785 | + ap_hook_register("read", read); | |
786 | + | |
787 | +Now a module wants to override the C<read()> call and registers the | |
788 | +C<my_read()> function: | |
789 | + | |
790 | + ap_hook_register("read", my_read); | |
791 | + | |
792 | +The function logically gets pushed onto a stack, so the execution order is the | |
793 | +reverse registering order, i.e. I<last registered - first called>. Now we can | |
794 | +replace the standard C<read()> call | |
795 | + | |
796 | + bytes = read(fd, buf, bufsize); | |
797 | + if (bytes == -1) | |
798 | + ...error... | |
799 | + | |
800 | +with the hook based call: | |
801 | + | |
802 | + rc = ap_hook_call("read", &bytes, fd, buf, bufsize); | |
803 | + if (rc == FALSE) | |
804 | + ...error... | |
805 | + | |
806 | +Now internally the following is done: The call `C<bytes = my_read(fd, buf, | |
807 | +bufsize)>' is done. When it returns not -1 (the decline value) nothing | |
808 | +more is done. But when C<my_read()> returns -1 the next function is tried: | |
809 | +`C<bytes = read(fd, buf, bufsize)>'. When this one also returns -1 you get | |
810 | +`rc == FALSE'. When it finally returns not -1 you get `rc == TRUE'. | |

1039 | +<P> | |
1040 | +The <CODE>Define</CODE> directive defines a variable which later can be | |
1041 | +expanded with the unsafe but short construct | |
1042 | +``<CODE>$</CODE><EM>variable</EM>'' or the safe but longer construct | |
1043 | +``<CODE>${</CODE><EM>variable</EM><CODE>}</CODE>'' on any configuration line. | |
1044 | +Do not intermix this with the third-party module <CODE>mod_macro</CODE>. The | |
1045 | +<CODE>mod_define</CODE> module doesn't provide a general macro mechanism, | |
1046 | +although one can consider variable substitutions as a special form of macros. | |
1047 | +Because the value of to which ``<CODE>$</CODE><EM>variable</EM>'' expands has | |
1048 | +to fit into one line. When you need macros which can span more lines, you've | |
1049 | +to use <CODE>mod_macro</CODE>. OTOH <CODE>mod_macro</CODE> cannot be used to | |
1050 | +expand a variable/macro on an arbitrary directive line. So, the typical use | |
1051 | +case of <CODE>mod_define</CODE> is to make strings <EM>variable</EM> (and this | |
1052 | +way easily changeable at one location) and not to <EM>bundle</EM> things | |
1053 | +together (as it's the typical use case for macros). | |
1054 | + | |
1055 | +<P> | |
1056 | +The syntax of the expansion construct ( | |
1057 | +``<CODE>${</CODE><EM>variable</EM><CODE>}</CODE>'') follows the Perl and Shell | |
1058 | +syntax, but can be changed via the <CODE>Define</CODE> directive, too. Four | |
1059 | +internal variables can be used for this. The default is: | |
1060 | + | |
1061 | +<BLOCKQUOTE> | |
1062 | +<PRE> | |
1063 | +Define mod_define::escape "\\" | |
1064 | +Define mod_define::dollar "$" | |
1065 | +Define mod_define::open "{" | |
1066 | +Define mod_define::close "}" | |
1067 | +</PRE> | |
1068 | +</BLOCKQUOTE> | |
1069 | + | |
1070 | +<P> | |
1071 | +When you need to escape some of the expansion constructs you place the | |
1072 | +mod_define::escape character in front of it. The default is the backslash as | |
1073 | +in Perl or the Shell. | |

2256 | +** ap_mm.c -- wrapper for MM shared memory library | |
2257 | +** | |
2258 | +** This file has two reason: | |
2259 | +** | |
2260 | +** 1. Under DSO context we need stubs inside the Apache core code | |
2261 | +** to make sure the MM library's code is actually available | |
2262 | +** to the module DSOs. | |
2263 | +** | |
2264 | +** 2. When the MM library cannot be built on the current platform | |
2265 | +** still provide dummy stubs so modules using the ap_mm_xxx() | |
2266 | +** functions can be still built. But modules should use | |
2267 | +** ap_mm_useable() to find out whether they really can use | |
2268 | +** the MM stuff. | |
