It is a recognition that authors should have +control over their work, and that it is a responsibility of the rest of +the Perl community to ensure that they retain this control. It is an +attempt to document the standards to which we, as Perl developers, intend +to hold ourselves. It is an attempt to write down rough guidelines about +the respect we owe each other as Perl developers. + +This statement is not a legal contract. This statement is not a legal +document in any way, shape, or form. Perl is distributed under the GNU +Public License and under the Artistic License; those are the precise legal +terms. This statement isn't about the law or licenses. It's about +community, mutual respect, trust, and good-faith cooperation. + +We recognize that the Perl core, defined as the software distributed with +the heart of Perl itself, is a joint project on the part of all of us. +>From time to time, a script, module, or set of modules (hereafter referred +to simply as a "module") will prove so widely useful and/or so integral to +the correct functioning of Perl itself that it should be distributed with +Perl core. This should never be done without the author's explicit +consent, and a clear recognition on all parts that this means the module +is being distributed under the same terms as Perl itself. A module author +should realize that inclusion of a module into the Perl core will +necessarily mean some loss of control over it, since changes may +occasionally have to be made on short notice or for consistency with the +rest of Perl. + +Once a module has been included in the Perl core, however, everyone +involved in maintaining Perl should be aware that the module is still the +property of the original author unless the original author explicitly +gives up their ownership of it. In particular: + + 1) The version of the module in the core should still be considered the + work of the original author. All patches, bug reports, and so forth + should be fed back to them. Their development directions should be + respected whenever possible. + + 2) Patches may be applied by the pumpkin holder without the explicit + cooperation of the module author if and only if they are very minor, + time-critical in some fashion (such as urgent security fixes), or if + the module author cannot be reached. Those patches must still be + given back to the author when possible, and if the author decides on + an alternate fix in their version, that fix should be strongly + preferred unless there is a serious problem with it. Any changes not + endorsed by the author should be marked as such, and the contributor + of the change acknowledged. + + 3) The version of the module distributed with Perl should, whenever + possible, be the latest version of the module as distributed by the + author (the latest non-beta version in the case of public Perl + releases), although the pumpkin holder may hold off on upgrading the + version of the module distributed with Perl to the latest version + until the latest version has had sufficient testing. + +In other words, the author of a module should be considered to have final +say on modifications to their module whenever possible (bearing in mind +that it's expected that everyone involved will work together and arrive at +reasonable compromises when there are disagreements). + +As a last resort, however: + + 4) If the author's vision of the future of their module is sufficiently + different from the vision of the pumpkin holder and perl5-porters as a + whole so as to cause serious problems for Perl, the pumpkin holder may + choose to formally fork the version of the module in the core from the + one maintained by the author. This should not be done lightly and + should *always* if at all possible be done only after direct input + from Larry. If this is done, it must then be made explicit in the + module as distributed with Perl core that it is a forked version and + that while it is based on the original author's work, it is no longer + maintained by them. This must be noted in both the documentation and + in the comments in the source of the module. + +Again, this should be a last resort only. Ideally, this should never +happen, and every possible effort at cooperation and compromise should be +made before doing this. If it does prove necessary to fork a module for +the overall health of Perl, proper credit must be given to the original +author in perpetuity and the decision should be constantly re-evaluated to +see if a remerging of the two branches is possible down the road. + +In all dealings with contributed modules, everyone maintaining Perl should +keep in mind that the code belongs to the original author, that they may +not be on perl5-porters at any given time, and that a patch is not +official unless it has been integrated into the author's copy of the +module. To aid with this, and with points #1, #2, and #3 above, contact +information for the authors of all contributed modules should be kept with +the Perl distribution. + +Finally, the Perl community as a whole recognizes that respect for +ownership of code, respect for artistic control, proper credit, and active +effort to prevent unintentional code skew or communication gaps is vital +to the health of the community and Perl itself. Members of a community +should not normally have to resort to rules and laws to deal with each +other, and this document, although it contains rules so as to be clear, is +about an attitude and general approach. The first step in any dispute +should be open communication, respect for opposing views, and an attempt +at a compromise. In nearly every circumstance nothing more will be +necessary, and certainly no more drastic measure should be used until +every avenue of communication and discussion has failed. + +-- +Version 1.2.

Set to ":" if ar can generate + random libraries or if random libraries are not supported + +rd_nodata (nblock_io.U): + This variable holds the return code from read() when no data is + present. It should be -1, but some systems return 0 when O_NDELAY is + used, which is a shame because you cannot make the difference between + no data and an EOF.. Sigh! + +rm (Loc.U): + This variable is be used internally by Configure to determine the + full pathname (if any) of the rm program. After Configure runs, + the value is reset to a plain "rm" and is not useful. + +rmail (Loc.U): + This variable is defined but not used by Configure. + The value is a plain '' and is not useful. + +runnm (usenm.U): + This variable contains 'true' or 'false' depending whether the + nm extraction should be performed or not, according to the value + of usenm and the flags on the Configure command line. + +scriptdir (scriptdir.U): + This variable holds the name of the directory in which the user wants + to put publicly scripts for the package in question.

Usually, this will be + /bin/sh, though it's possible that some systems will have /bin/ksh, + /bin/pdksh, /bin/ash, /bin/bash, or even something such as + D:/bin/sh.exe. + This unit comes before Options.U, so you can't set sh with a '-D' + option, though you can override this (and startsh) + with '-O -Dsh=/bin/whatever -Dstartsh=whatever' + +shar (Loc.U): + This variable is defined but not used by Configure. + The value is a plain '' and is not useful. + +sharpbang (spitshell.U): + This variable contains the string #! if this system supports that + construct. + +shmattype (d_shmat.U): + This symbol contains the type of pointer returned by shmat(). + It can be 'void *' or 'char *'. + +shortsize (intsize.U): + This variable contains the value of the SHORTSIZE symbol which + indicates to the C program how many bytes there are in a short. + +shrpenv (libperl.U): + If the user builds a shared libperl.so, then we need to tell the + 'perl' executable where it will be able to find the installed libperl.so. + One way to do this on some systems is to set the environment variable + LD_RUN_PATH to the directory that will be the final location of the + shared libperl.so. The makefile can use this with something like + $shrpenv $(CC) -o perl perlmain.o $libperl $libs + Typical values are + shrpenv="env LD_RUN_PATH=$archlibexp/CORE" + or + shrpenv='' + See the main perl Makefile.SH for actual working usage. + Alternatively, we might be able to use a command line option such + as -R $archlibexp/CORE (Solaris, NetBSD) or -Wl,-rpath + $archlibexp/CORE (Linux). + +shsharp (spitshell.U): + This variable tells further Configure units whether your sh can + handle # comments. + +sig_name (sig_name.U): + This variable holds the signal names, space separated. The leading + SIG in signal name is removed. A ZERO is prepended to the + list. This is currently not used. + +sig_name_init (sig_name.U): + This variable holds the signal names, enclosed in double quotes and + separated by commas, suitable for use in the SIG_NAME definition + below. A "ZERO" is prepended to the list, and the list is + terminated with a plain 0. The leading SIG in signal names + is removed. See sig_num. + +sig_num (sig_name.U): + This variable holds the signal numbers, comma separated.

It is up to + the Makefile to use this variable and set VPATH accordingly to + find the sources remotely. + +ssizetype (ssizetype.U): + This variable defines ssizetype to be something like ssize_t, + long or int. It is used by functions that return a count + of bytes or an error condition.

Of course, that leading line must be followed by the classical + perl idiom: + eval 'exec perl -S $0 ${1+"$@"}' + if $running_under_some_shell; + to guarantee perl startup should the shell execute the script. Note + that this magic incatation is not understood by csh. + +startsh (startsh.U): + This variable contains the string to put on the front of a shell + script to make sure (hopefully) that it runs with sh and not some + other shell. + +static_ext (Extensions.U): + This variable holds a list of XS extension files we want to + link statically into the package.

But, some users are unsure as to the I<right> way to prepare a patch +and end up submitting seriously malformed patches. This makes it very +difficult for the current maintainer to integrate said patches into their +distribution. This document sets out usage guidelines for patches in an +attempt to make everybody's life easier. + +=head2 Common problems + +The most common problems appear to be patches being mangled by certain +mailers (I won't name names, but most of these seem to be originating on +boxes running a certain popular commercial operating system). Other problems +include patches not rooted in the appropriate place in the directory structure, +and patches not produced using standard utilities (such as diff). + +=head1 Proper Patch Guidelines + +=head2 How to prepare your patch + +=over 4 + +=item Creating your patch + +First, back up the original files. This can't be stressed enough, +back everything up _first_. + +Also, please create patches against a clean distribution of the perl source. +This insures that everyone else can apply your patch without clobbering their +source tree. + +=item diff + +While individual tastes vary (and are not the point here) patches should +be created using either C<-u> or C<-c> arguments to diff. These produce, +respectively, unified diffs (where the changed line appears immediately next +to the original) and context diffs (where several lines surrounding the changes +are included). See the manpage for diff for more details. + +Also, the preferred method for patching is - + +C<diff [C<-c> | C<-u>] E<lt>old-fileE<gt> E<lt>new-fileE<gt>> + +Note the order of files. + +Also, if your patch is to the core (rather than to a module) it +is better to create it as a context diff as some machines have +broken patch utilities that choke on unified diffs. + +GNU diff has many desirable features not provided by most vendor-supplied +diffs. Some examples using GNU diff: + + # generate a patch for a newly added file + % diff -u /dev/null new/file + + # generate a patch to remove a file (patch > v2.4 will remove it cleanly) + % diff -u old/goner /dev/null + + # get additions, deletions along with everything else, recursively + % diff -ruN olddir newdir + + # ignore whitespace + % diff -bu a/file b/file + + # show function name in every hunk (safer, more informative) + % diff -u -F '^[_a-zA-Z0-9]+ *(' old/file new/file + + +=item Directories + +Patches should be generated from the source root directory, not from the +directory that the patched file resides in. This insures that the maintainer +patches the proper file and avoids name collisions (especially common when trying +to apply patches to files that appear in both $src_root/ext/* and $src_root/lib/*). +It is better to diff the file in $src_root/ext than the file in $src_root/lib. + +=item Filenames + +The most usual convention when submitting patches for a single file is to make +your changes to a copy of the file with the same name as the original. Rename +the original file in such a way that it is obvious what is being patched ($file~ or +$file.old seem to be popular). + +If you are submitting patches that affect multiple files then you should backup +the entire directory tree (to $source_root.old/ for example). This will allow +C<diff C<-c> E<lt>old-dirE<gt> E<lt>new-dirE<gt>> to create all the patches +at once. + +=back + +=head2 What to include in your patch + +=over 4 + +=item Description of problem + +The first thing you should include is a description of the problem that +the patch corrects. If it is a code patch (rather than a documentation +patch) you should also include a small test case that illustrates the +bug. + +=item Direction for application + +You should include instructions on how to properly apply your patch. +These should include the files affected, any shell scripts or commands +that need to be run before or after application of the patch, and +the command line necessary for application. + +=item If you have a code patch + +If you are submitting a code patch there are several other things that +you need to do. + +=over 4 + +=item Comments, Comments, Comments + +Be sure to adequately comment your code. While commenting every +line is unnecessary, anything that takes advantage of side effects of +operators, that creates changes that will be felt outside of the +function being patched, or that others may find confusing should +be documented. If you are going to err, it is better to err on the +side of adding too many comments than too few. + +=item Style + +Please follow the indentation style and nesting style in use in the +block of code that you are patching. + +=item Testsuite + +When submitting a patch you should make every effort to also include +an addition to perl's regression tests to properly exercise your +patch. Your testsuite additions should generally follow these +guidelines (courtesy of Gurusamy Sarathy (gsar@engin.umich.edu))- + + Know what you're testing.

You'll have the satisfaction of having contributed to perl, +others will have an easy time using your work, and it should be easier +for the maintainers to coordinate the occasionally large numbers of +patches received. + +Also, just because you're not a brilliant coder doesn't mean that you can't +contribute. As valuable as code patches are there is always a need for better +documentation (especially considering the general level of joy that most +programmers feel when forced to sit down and write docs). If all you do +is patch the documentation you have still contributed more than the person +who sent in an amazing new feature that noone can use because noone understands +the code (what I'm getting at is that documentation is both the hardest part to +do (because everyone hates doing it) and the most valuable). + +Mostly, when contributing patches, imagine that it is B<you> receiving hundreds +of patches and that it is B<your> responsibility to integrate them into the source. +Obviously you'd want the patches to be as easy to apply as possible.

Still, I hope parts of it will be useful, +so I'm releasing it even though it's not done. + +For the most part, it's a collection of anecdotal information that +already assumes some familiarity with the Perl sources. I really need +an introductory section that describes the organization of the sources +and all the various auxiliary files that are part of the distribution. + +=head1 Where Do I Get Perl Sources and Related Material? + +The Comprehensive Perl Archive Network (or CPAN) is the place to go. +There are many mirrors, but the easiest thing to use is probably +http://www.perl.com/CPAN/README.html , which automatically points you to a +mirror site "close" to you. + +=head2 Perl5-porters mailing list + +The mailing list perl5-porters@perl.org +is the main group working with the development of perl. If you're +interested in all the latest developments, you should definitely +subscribe. The list is high volume, but generally has a +fairly low noise level. + +Subscribe by sending the message (in the body of your letter) + + subscribe perl5-porters + +to perl5-porters-request@perl.org . + +Archives of the list are held at: + + http://www.rosat.mpe-garching.mpg.de/mailing-lists/perl-porters/ + +=head1 How are Perl Releases Numbered? + +Perl version numbers are floating point numbers, such as 5.004. +(Observations about the imprecision of floating point numbers for +representing reality probably have more relevance than you might +imagine :-) The major version number is 5 and the '004' is the +patchlevel. (Questions such as whether or not '004' is really a minor +version number can safely be ignored.:) + +The version number is available as the magic variable $], +and can be used in comparisons, e.g. + + print "You've got an old perl\n" if $] < 5.002; + +You can also require particular version (or later) with + + use 5.002; + +At some point in the future, we may need to decide what to call the +next big revision. In the .package file used by metaconfig to +generate Configure, there are two variables that might be relevant: +$baserev=5.0 and $package=perl5. At various times, I have suggested +we might change them to $baserev=5.1 and $package=perl5.1 if want +to signify a fairly major update. Or, we might want to jump to perl6. +Let's worry about that problem when we get there. + +=head2 Subversions + +In addition, there may be "developer" sub-versions available. These +are not official releases. They may contain unstable experimental +features, and are subject to rapid change. Such developer +sub-versions are numbered with sub-version numbers. For example, +version 5.003_04 is the 4'th developer version built on top of +5.003. It might include the _01, _02, and _03 changes, but it +also might not. Sub-versions are allowed to be subversive. (But see +the next section for recent changes.) + +These sub-versions can also be used as floating point numbers, so +you can do things such as + + print "You've got an unstable perl\n" if $] == 5.00303; + +You can also require particular version (or later) with + + use 5.003_03; # the "_" is optional + +Sub-versions produced by the members of perl5-porters are usually +available on CPAN in the F<src/5.0/unsupported> directory. + +=head2 Maintenance and Development Subversions + +As an experiment, starting with version 5.004, subversions _01 through +_49 will be reserved for bug-fix maintenance releases, and subversions +_50 through _99 will be available for unstable development versions. + +The separate bug-fix track is being established to allow us an easy +way to distribute important bug fixes without waiting for the +developers to untangle all the other problems in the current +developer's release. + +Trial releases of bug-fix maintenance releases are announced on +perl5-porters. Trial releases use the new subversion number (to avoid +testers installing it over the previous release) and include a 'local +patch' entry in patchlevel.h. + +Watch for announcements of maintenance subversions in +comp.lang.perl.announce. + +The first rule of maintenance work is "First, do no harm." + +=head2 Why such a complicated scheme? + +Two reasons, really. At least. + +First, we need some way to identify and release collections of patches +that are known to have new features that need testing and exploration. The +subversion scheme does that nicely while fitting into the +C<use 5.004;> mold. + +Second, since most of the folks who help maintain perl do so on a +free-time voluntary basis, perl development does not proceed at a +precise pace, though it always seems to be moving ahead quickly. +We needed some way to pass around the "patch pumpkin" to allow +different people chances to work on different aspects of the +distribution without getting in each other's way. It wouldn't be +constructive to have multiple people working on incompatible +implementations of the same idea. Instead what was needed was +some kind of "baton" or "token" to pass around so everyone knew +whose turn was next. + +=head2 Why is it called the patch pumpkin? + +Chip Salzenberg gets credit for that, with a nod to his cow orker, +David Croy. We had passed around various names (baton, token, hot +potato) but none caught on. Then, Chip asked: + +[begin quote] + + Who has the patch pumpkin? + +To explain: David Croy once told me once that at a previous job, +there was one tape drive and multiple systems that used it for backups. +But instead of some high-tech exclusion software, they used a low-tech +method to prevent multiple simultaneous backups: a stuffed pumpkin. +No one was allowed to make backups unless they had the "backup pumpkin". + +[end quote] + +The name has stuck. + +=head1 Philosophical Issues in Patching Perl + +There are no absolute rules, but there are some general guidelines I +have tried to follow as I apply patches to the perl sources. +(This section is still under construction.) + +=head2 Solve problems as generally as possible + +Never implement a specific restricted solution to a problem when you +can solve the same problem in a more general, flexible way. + +For example, for dynamic loading to work on some SVR4 systems, we had +to build a shared libperl.so library. In order to build "FAT" binaries +on NeXT 4.0 systems, we had to build a special libperl library. Rather +than continuing to build a contorted nest of special cases, I +generalized the process of building libperl so that NeXT and SVR4 users +could still get their work done, but others could build a shared +libperl if they wanted to as well. + +=head2 Seek consensus on major changes + +If you are making big changes, don't do it in secret. Discuss the +ideas in advance on perl5-porters. + +=head2 Keep the documentation up-to-date + +If your changes may affect how users use perl, then check to be sure +that the documentation is in sync with your changes. Be sure to +check all the files F<pod/*.pod> and also the F<INSTALL> document. + +Consider writing the appropriate documentation first and then +implementing your change to correspond to the documentation. + +=head2 Avoid machine-specific #ifdef's + +To the extent reasonable, try to avoid machine-specific #ifdef's in +the sources. Instead, use feature-specific #ifdef's. The reason is +that the machine-specific #ifdef's may not be valid across major +releases of the operating system. Further, the feature-specific tests +may help out folks on another platform who have the same problem. + +=head2 Allow for lots of testing + +We should never release a main version without testing it as a +subversion first. + +=head2 Test popular applications and modules. + +We should never release a main version without testing whether or not +it breaks various popular modules and applications. A partial list of +such things would include majordomo, metaconfig, apache, Tk, CGI, +libnet, and libwww, to name just a few. Of course it's quite possible +that some of those things will be just plain broken and need to be fixed, +but, in general, we ought to try to avoid breaking widely-installed +things. + +=head2 Automate generation of derivative files + +The F<embed.h>, F<keywords.h>, F<opcode.h>, and F<perltoc.pod> files +are all automatically generated by perl scripts. In general, don't +patch these directly; patch the data files instead. + +F<Configure> and F<config_h.SH> are also automatically generated by +B<metaconfig>. In general, you should patch the metaconfig units +instead of patching these files directly. However, very minor changes to +F<Configure> may be made in between major sync-ups with the metaconfig +units, which tends to be complicated operations. But be careful, this +can quickly spiral out of control. Running metaconfig is not really +hard. + +Finally, the sample files in the F<Porting/> subdirectory are +generated automatically by the script F<U/mksample> included +with the metaconfig units. See L<"run metaconfig"> below for +information on obtaining the metaconfig units. + +=head1 How to Make a Distribution + +There really ought to be a 'make dist' target, but there isn't. +The 'dist' suite of tools also contains a number of tools that I haven't +learned how to use yet. Some of them may make this all a bit easier. + +Here are the steps I go through to prepare a patch & distribution. + +Lots of it could doubtless be automated but isn't. The Porting/makerel +(make release) perl script does now help automate some parts of it. + +=head2 Announce your intentions + +First, you should volunteer out loud to take the patch pumpkin. It's +generally counter-productive to have multiple people working in secret +on the same thing. + +At the same time, announce what you plan to do with the patch pumpkin, +to allow folks a chance to object or suggest alternatives, or do it for +you. Naturally, the patch pumpkin holder ought to incorporate various +bug fixes and documentation improvements that are posted while he or +she has the pumpkin, but there might also be larger issues at stake. + +One of the precepts of the subversion idea is that we shouldn't give +the patch pumpkin to anyone unless we have some idea what he or she +is going to do with it. + +=head2 refresh pod/perltoc.pod + +Presumably, you have done a full C<make> in your working source +directory. Before you C<make spotless> (if you do), and if you have +changed any documentation in any module or pod file, change to the +F<pod> directory and run C<make toc>. + +=head2 run installhtml to check the validity of the pod files + +=head2 update patchlevel.h + +Don't be shy about using the subversion number, even for a relatively +modest patch. We've never even come close to using all 99 subversions, +and it's better to have a distinctive number for your patch. If you +need feedback on your patch, go ahead and issue it and promise to +incorporate that feedback quickly (e.g. within 1 week) and send out a +second patch. + +=head2 run metaconfig + +If you need to make changes to Configure or config_h.SH, it may be best to +change the appropriate metaconfig units instead, and regenerate Configure. + + metaconfig -m + +will regenerate Configure and config_h.SH. Much more information +on obtaining and running metaconfig is in the F<U/README> file +that comes with Perl's metaconfig units. Perl's metaconfig units +should be available on CPAN. A set of units that will work with +perl5.005 is in the file F<mc_units-5.005_00-01.tar.gz> under +http://www.perl.com/CPAN/authors/id/ANDYD/ . The mc_units tar file +should be unpacked in your main perl source directory. Note: those +units were for use with 5.005. There may have been changes since then. +Check for later versions or contact perl5-porters@perl.org to obtain a +pointer to the current version. + +Alternatively, do consider if the F<*ish.h> files might be a better +place for your changes. + +=head2 MANIFEST + +Make sure the MANIFEST is up-to-date. You can use dist's B<manicheck> +program for this. You can also use + + perl -w -MExtUtils::Manifest=fullcheck -e fullcheck + +Both commands will also list extra files in the directory that are not +listed in MANIFEST. + +The MANIFEST is normally sorted. + +If you are using metaconfig to regenerate Configure, then you should note +that metaconfig actually uses MANIFEST.new, so you want to be sure +MANIFEST.new is up-to-date too. I haven't found the MANIFEST/MANIFEST.new +distinction particularly useful, but that's probably because I still haven't +learned how to use the full suite of tools in the dist distribution. + +=head2 Check permissions + +All the tests in the t/ directory ought to be executable. The +main makefile used to do a 'chmod t/*/*.t', but that resulted in +a self-modifying distribution--something some users would strongly +prefer to avoid. The F<t/TEST> script will check for this +and do the chmod if needed, but the tests still ought to be +executable. + +In all, the following files should probably be executable: + + Configure + configpm + configure.gnu + embed.pl + installperl + installman + keywords.pl + myconfig + opcode.pl + perly.fixer + t/TEST + t/*/*.t + *.SH + vms/ext/Stdio/test.pl + vms/ext/filespec.t + x2p/*.SH + +Other things ought to be readable, at least :-). + +Probably, the permissions for the files could be encoded in MANIFEST +somehow, but I'm reluctant to change MANIFEST itself because that +could break old scripts that use MANIFEST. + +I seem to recall that some SVR3 systems kept some sort of file that listed +permissions for system files; something like that might be appropriate. + +=head2 Run Configure + +This will build a config.sh and config.h. You can skip this if you haven't +changed Configure or config_h.SH at all. I use the following command + + sh Configure -Dprefix=/opt/perl -Doptimize=-O -Dusethreads \ + -Dcf_by='yourname' \ + -Dcf_email='yourname@yourhost.yourplace.com' \ + -Dperladmin='yourname@yourhost.yourplace.com' \ + -Dmydomain='.yourplace.com' \ + -Dmyhostname='yourhost' \ + -des + +=head2 Update Porting/config.sh and Porting/config_H + +[XXX +This section needs revision. We're currently working on easing +the task of keeping the vms, win32, and plan9 config.sh info +up-to-date. The plan is to use keep up-to-date 'canned' config.sh +files in the appropriate subdirectories and then generate 'canned' +config.h files for vms, win32, etc. from the generic config.sh file. +This is to ease maintenance. When Configure gets updated, the parts +sometimes get scrambled around, and the changes in config_H can +sometimes be very hard to follow. config.sh, on the other hand, can +safely be sorted, so it's easy to track (typically very small) changes +to config.sh and then propoagate them to a canned 'config.h' by any +number of means, including a perl script in win32/ or carrying +config.sh and config_h.SH to a Unix system and running sh +config_h.SH.) +XXX] + +The Porting/config.sh and Porting/config_H files are provided to +help those folks who can't run Configure. It is important to keep +them up-to-date. If you have changed config_h.SH, those changes must +be reflected in config_H as well. (The name config_H was chosen to +distinguish the file from config.h even on case-insensitive file systems.) +Simply edit the existing config_H file; keep the first few explanatory +lines and then copy your new config.h below. + +It may also be necessary to update win32/config.?c, vms/config.vms and +plan9/config.plan9, though you should be quite careful in doing so if +you are not familiar with those systems. You might want to issue your +patch with a promise to quickly issue a follow-up that handles those +directories. + +=head2 make run_byacc + +If you have byacc-1.8.2 (available from CPAN), and if there have been +changes to F<perly.y>, you can regenerate the F<perly.c> file. The +run_byacc makefile target does this by running byacc and then applying +some patches so that byacc dynamically allocates space, rather than +having fixed limits. This patch is handled by the F<perly.fixer> +script. Depending on the nature of the changes to F<perly.y>, you may +or may not have to hand-edit the patch to apply correctly. If you do, +you should include the edited patch in the new distribution. If you +have byacc-1.9, the patch won't apply cleanly. Changes to the printf +output statements mean the patch won't apply cleanly. Long ago I +started to fix F<perly.fixer> to detect this, but I never completed the +task. + +Some additional notes from Larry on this: + +Don't forget to regenerate perly_c.diff. + + byacc -d perly.y + mv y.tab.c perly.c + patch perly.c <perly_c.diff + # manually apply any failed hunks + diff -c2 perly.c.orig perly.c >perly_c.diff + +One chunk of lines that often fails begins with + + #line 29 "perly.y" + +and ends one line before + + #define YYERRCODE 256 + +This only happens when you add or remove a token type. I suppose this +could be automated, but it doesn't happen very often nowadays. + +Larry + +=head2 make regen_headers + +The F<embed.h>, F<keywords.h>, and F<opcode.h> files are all automatically +generated by perl scripts. Since the user isn't guaranteed to have a +working perl, we can't require the user to generate them. Hence you have +to, if you're making a distribution. + +I used to include rules like the following in the makefile: + + # The following three header files are generated automatically + # The correct versions should be already supplied with the perl kit, + # in case you don't have perl or 'sh' available. + # The - is to ignore error return codes in case you have the source + # installed read-only or you don't have perl yet. + keywords.h: keywords.pl + @echo "Don't worry if this fails." + - perl keywords.pl + + +However, I got B<lots> of mail consisting of people worrying because the +command failed. I eventually decided that I would save myself time +and effort by manually running C<make regen_headers> myself rather +than answering all the questions and complaints about the failing +command. + +=head2 global.sym, interp.sym and perlio.sym + +Make sure these files are up-to-date. Read the comments in these +files and in perl_exp.SH to see what to do. + +=head2 Binary compatibility + +If you do change F<global.sym> or F<interp.sym>, think carefully about +what you are doing. To the extent reasonable, we'd like to maintain +souce and binary compatibility with older releases of perl. That way, +extensions built under one version of perl will continue to work with +new versions of perl. + +Of course, some incompatible changes may well be necessary. I'm just +suggesting that we not make any such changes without thinking carefully +about them first. If possible, we should provide +backwards-compatibility stubs. There's a lot of XS code out there. +Let's not force people to keep changing it. + +=head2 Changes + +Be sure to update the F<Changes> file. Try to include both an overall +summary as well as detailed descriptions of the changes. Your +audience will include other developers and users, so describe +user-visible changes (if any) in terms they will understand, not in +code like "initialize foo variable in bar function". + +There are differing opinions on whether the detailed descriptions +ought to go in the Changes file or whether they ought to be available +separately in the patch file (or both). There is no disagreement that +detailed descriptions ought to be easily available somewhere. + +=head2 Todo + +The F<Todo> file contains a roughly-catgorized unordered list of +aspects of Perl that could use enhancement, features that could be +added, areas that could be cleaned up, and so on. During your term as +pumpkin-holder, you will probably address some of these issues, and +perhaps identify others which, while you decide not to address them +this time around, may be tackled in the future. Update the file +reflect the situation as it stands when you hand over the pumpkin. + +You might like, early in your pumpkin-holding career, to see if you +can find champions for partiticular issues on the to-do list: an issue +owned is an issue more likely to be resolved. + +There are also some more porting-specific L<Todo> items later in this +file. + +=head2 OS/2-specific updates + +In the os2 directory is F<diff.configure>, a set of OS/2-specific +diffs against B<Configure>. If you make changes to Configure, you may +want to consider regenerating this diff file to save trouble for the +OS/2 maintainer. + +You can also consider the OS/2 diffs as reminders of portability +things that need to be fixed in Configure. + +=head2 VMS-specific updates + +If you have changed F<perly.y>, then you may want to update +F<vms/perly_{h,c}.vms> by running C<perl vms/vms_yfix.pl>. + +The Perl version number appears in several places under F<vms>. +It is courteous to update these versions. For example, if you are +making 5.004_42, replace "5.00441" with "5.00442". + +=head2 Making the new distribution + +Suppose, for example, that you want to make version 5.004_08. Then you can +do something like the following + + mkdir ../perl5.004_08 + awk '{print $1}' MANIFEST | cpio -pdm ../perl5.004_08 + cd ../ + tar cf perl5.004_08.tar perl5.004_08 + gzip --best perl5.004_08.tar + +These steps, with extra checks, are automated by the Porting/makerel +script. + +=head2 Making a new patch + +I find the F<makepatch> utility quite handy for making patches. +You can obtain it from any CPAN archive under +http://www.perl.com/CPAN/authors/Johan_Vromans/ . There are a couple +of differences between my version and the standard one. I have mine do +a + + # Print a reassuring "End of Patch" note so people won't + # wonder if their mailer truncated patches. + print "\n\nEnd of Patch.\n"; + +at the end. That's because I used to get questions from people asking +if their mail was truncated. + +It also writes Index: lines which include the new directory prefix +(change Index: print, approx line 294 or 310 depending on the version, +to read: print PATCH ("Index: $newdir$new\n");). That helps patches +work with more POSIX conformant patch programs. + +Here's how I generate a new patch. I'll use the hypothetical +5.004_07 to 5.004_08 patch as an example. + + # unpack perl5.004_07/ + gzip -d -c perl5.004_07.tar.gz | tar -xof - + # unpack perl5.004_08/ + gzip -d -c perl5.004_08.tar.gz | tar -xof - + makepatch perl5.004_07 perl5.004_08 > perl5.004_08.pat + +Makepatch will automatically generate appropriate B<rm> commands to remove +deleted files. Unfortunately, it will not correctly set permissions +for newly created files, so you may have to do so manually. For example, +patch 5.003_04 created a new test F<t/op/gv.t> which needs to be executable, +so at the top of the patch, I inserted the following lines: + + # Make a new test + touch t/op/gv.t + chmod +x t/opt/gv.t + +Now, of course, my patch is now wrong because makepatch didn't know I +was going to do that command, and it patched against /dev/null. + +So, what I do is sort out all such shell commands that need to be in the +patch (including possible mv-ing of files, if needed) and put that in the +shell commands at the top of the patch. Next, I delete all the patch parts +of perl5.004_08.pat, leaving just the shell commands. Then, I do the +following: + + cd perl5.004_07 + sh ../perl5.004_08.pat + cd .. + makepatch perl5.004_07 perl5.004_08 >> perl5.004_08.pat + +(Note the append to preserve my shell commands.) +Now, my patch will line up with what the end users are going to do. + +=head2 Testing your patch + +It seems obvious, but be sure to test your patch. That is, verify that +it produces exactly the same thing as your full distribution. + + rm -rf perl5.004_07 + gzip -d -c perl5.004_07.tar.gz | tar -xf - + cd perl5.004_07 + sh ../perl5.004_08.pat + patch -p1 -N < ../perl5.004_08.pat + cd .. + gdiff -r perl5.004_07 perl5.004_08 + +where B<gdiff> is GNU diff. Other diff's may also do recursive checking. + +=head2 More testing + +Again, it's obvious, but you should test your new version as widely as you +can. You can be sure you'll hear about it quickly if your version doesn't +work on both ANSI and pre-ANSI compilers, and on common systems such as +SunOS 4.1.[34], Solaris, and Linux. + +If your changes include conditional code, try to test the different +branches as thoroughly as you can. For example, if your system +supports dynamic loading, you can also test static loading with + + sh Configure -Uusedl + +You can also hand-tweak your config.h to try out different #ifdef +branches. + +=head1 Common Gotcha's + +=over 4 + +=item #elif + +The '#elif' preprocessor directive is not understood on all systems. +Specifically, I know that Pyramids don't understand it. Thus instead of the +simple + + #if defined(I_FOO) + # include <foo.h> + #elif defined(I_BAR) + # include <bar.h> + #else + # include <fubar.h> + #endif + +You have to do the more Byzantine + + #if defined(I_FOO) + # include <foo.h> + #else + # if defined(I_BAR) + # include <bar.h> + # else + # include <fubar.h> + # endif + #endif + +Incidentally, whitespace between the leading '#' and the preprocessor +command is not guaranteed, but is very portable and you may use it freely. +I think it makes things a bit more readable, especially once things get +rather deeply nested. I also think that things should almost never get +too deeply nested, so it ought to be a moot point :-) + +=item Probably Prefer POSIX + +It's often the case that you'll need to choose whether to do +something the BSD-ish way or the POSIX-ish way. It's usually not +a big problem when the two systems use different names for similar +functions, such as memcmp() and bcmp(). The perl.h header file +handles these by appropriate #defines, selecting the POSIX mem*() +functions if available, but falling back on the b*() functions, if +need be. + +More serious is the case where some brilliant person decided to +use the same function name but give it a different meaning or +calling sequence :-). getpgrp() and setpgrp() come to mind. +These are a real problem on systems that aim for conformance to +one standard (e.g. POSIX), but still try to support the other way +of doing things (e.g. BSD). My general advice (still not really +implemented in the source) is to do something like the following. +Suppose there are two alternative versions, fooPOSIX() and +fooBSD(). + + #ifdef HAS_FOOPOSIX + /* use fooPOSIX(); */ + #else + # ifdef HAS_FOOBSD + /* try to emulate fooPOSIX() with fooBSD(); + perhaps with the following: */ + # define fooPOSIX fooBSD + # else + # /* Uh, oh. We have to supply our own. */ + # define fooPOSIX Perl_fooPOSIX + # endif + #endif + +=item Think positively + +If you need to add an #ifdef test, it is usually easier to follow if you +think positively, e.g. + + #ifdef HAS_NEATO_FEATURE + /* use neato feature */ + #else + /* use some fallback mechanism */ + #endif + +rather than the more impenetrable + + #ifndef MISSING_NEATO_FEATURE + /* Not missing it, so we must have it, so use it */ + #else + /* Are missing it, so fall back on something else. */ + #endif + +Of course for this toy example, there's not much difference. But when +the #ifdef's start spanning a couple of screen fulls, and the #else's +are marked something like + + #else /* !MISSING_NEATO_FEATURE */ + +I find it easy to get lost. + +=item Providing Missing Functions -- Problem + +Not all systems have all the neat functions you might want or need, so +you might decide to be helpful and provide an emulation. This is +sound in theory and very kind of you, but please be careful about what +you name the function. Let me use the C<pause()> function as an +illustration. + +Perl5.003 has the following in F<perl.h> + + #ifndef HAS_PAUSE + #define pause() sleep((32767<<16)+32767) + #endif + +Configure sets HAS_PAUSE if the system has the pause() function, so +this #define only kicks in if the pause() function is missing. +Nice idea, right? + +Unfortunately, some systems apparently have a prototype for pause() +in F<unistd.h>, but don't actually have the function in the library. +(Or maybe they do have it in a library we're not using.) + +Thus, the compiler sees something like + + extern int pause(void); + /* . . . */ + #define pause() sleep((32767<<16)+32767) + +and dies with an error message. (Some compilers don't mind this; +others apparently do.) + +To work around this, 5.003_03 and later have the following in perl.h: + + /* Some unistd.h's give a prototype for pause() even though + HAS_PAUSE ends up undefined. This causes the #define + below to be rejected by the compiler. Sigh. + */ + #ifdef HAS_PAUSE + # define Pause pause + #else + # define Pause() sleep((32767<<16)+32767) + #endif + +This works. + +The curious reader may wonder why I didn't do the following in +F<util.c> instead: + + #ifndef HAS_PAUSE + void pause() + { + sleep((32767<<16)+32767); + } + #endif + +That is, since the function is missing, just provide it. +Then things would probably be been alright, it would seem. + +Well, almost. It could be made to work. The problem arises from the +conflicting needs of dynamic loading and namespace protection. + +For dynamic loading to work on AIX (and VMS) we need to provide a list +of symbols to be exported. This is done by the script F<perl_exp.SH>, +which reads F<global.sym> and F<interp.sym>. Thus, the C<pause> +symbol would have to be added to F<global.sym> So far, so good. + +On the other hand, one of the goals of Perl5 is to make it easy to +either extend or embed perl and link it with other libraries. This +means we have to be careful to keep the visible namespace "clean". +That is, we don't want perl's global variables to conflict with +those in the other application library. Although this work is still +in progress, the way it is currently done is via the F<embed.h> file. +This file is built from the F<global.sym> and F<interp.sym> files, +since those files already list the globally visible symbols. If we +had added C<pause> to global.sym, then F<embed.h> would contain the +line + + #define pause Perl_pause + +and calls to C<pause> in the perl sources would now point to +C<Perl_pause>. Now, when B<ld> is run to build the F<perl> executable, +it will go looking for C<perl_pause>, which probably won't exist in any +of the standard libraries. Thus the build of perl will fail. + +Those systems where C<HAS_PAUSE> is not defined would be ok, however, +since they would get a C<Perl_pause> function in util.c. The rest of +the world would be in trouble. + +And yes, this scenario has happened. On SCO, the function C<chsize> +is available. (I think it's in F<-lx>, the Xenix compatibility +library.) Since the perl4 days (and possibly before), Perl has +included a C<chsize> function that gets called something akin to + + #ifndef HAS_CHSIZE + I32 chsize(fd, length) + /* . . . */ + #endif + +When 5.003 added + + #define chsize Perl_chsize + +to F<embed.h>, the compile started failing on SCO systems. + +The "fix" is to give the function a different name. The one +implemented in 5.003_05 isn't optimal, but here's what was done: + + #ifdef HAS_CHSIZE + # ifdef my_chsize /* Probably #defined to Perl_my_chsize in embed.h */ + # undef my_chsize + # endif + # define my_chsize chsize + #endif + +My explanatory comment in patch 5.003_05 said: + + Undef and then re-define my_chsize from Perl_my_chsize to + just plain chsize if this system HAS_CHSIZE. This probably only + applies to SCO. This shows the perils of having internal + functions with the same name as external library functions :-). + +Now, we can safely put C<my_chsize> in F<global.sym>, export it, and +hide it with F<embed.h>. + +To be consistent with what I did for C<pause>, I probably should have +called the new function C<Chsize>, rather than C<my_chsize>. +However, the perl sources are quite inconsistent on this (Consider +New, Mymalloc, and Myremalloc, to name just a few.) + +There is a problem with this fix, however, in that C<Perl_chsize> +was available as a F<libperl.a> library function in 5.003, but it +isn't available any more (as of 5.003_07). This means that we've +broken binary compatibility. This is not good. + +=item Providing missing functions -- some ideas + +We currently don't have a standard way of handling such missing +function names. Right now, I'm effectively thinking aloud about a +solution. Some day, I'll try to formally propose a solution. + +Part of the problem is that we want to have some functions listed as +exported but not have their names mangled by embed.h or possibly +conflict with names in standard system headers. We actually already +have such a list at the end of F<perl_exp.SH> (though that list is +out-of-date): + + # extra globals not included above. + cat <<END >> perl.exp + perl_init_ext + perl_init_fold + perl_init_i18nl14n + perl_alloc + perl_construct + perl_destruct + perl_free + perl_parse + perl_run + perl_get_sv + perl_get_av + perl_get_hv + perl_get_cv + perl_call_argv + perl_call_pv + perl_call_method + perl_call_sv + perl_requirepv + safecalloc + safemalloc + saferealloc + safefree + +This still needs much thought, but I'm inclined to think that one +possible solution is to prefix all such functions with C<perl_> in the +source and list them along with the other C<perl_*> functions in +F<perl_exp.SH>. + +Thus, for C<chsize>, we'd do something like the following: + + /* in perl.h */ + #ifdef HAS_CHSIZE + # define perl_chsize chsize + #endif + +then in some file (e.g. F<util.c> or F<doio.c>) do + + #ifndef HAS_CHSIZE + I32 perl_chsize(fd, length) + /* implement the function here . . . */ + #endif + +Alternatively, we could just always use C<chsize> everywhere and move +C<chsize> from F<global.sym> to the end of F<perl_exp.SH>. That would +probably be fine as long as our C<chsize> function agreed with all the +C<chsize> function prototypes in the various systems we'll be using. +As long as the prototypes in actual use don't vary that much, this is +probably a good alternative. (As a counter-example, note how Configure +and perl have to go through hoops to find and use get Malloc_t and +Free_t for C<malloc> and C<free>.) + +At the moment, this latter option is what I tend to prefer. + +=item All the world's a VAX + +Sorry, showing my age:-). Still, all the world is not BSD 4.[34], +SVR4, or POSIX. Be aware that SVR3-derived systems are still quite +common (do you have any idea how many systems run SCO?) If you don't +have a bunch of v7 manuals handy, the metaconfig units (by default +installed in F</usr/local/lib/dist/U>) are a good resource to look at +for portability. + +=back + +=head1 Miscellaneous Topics + +=head2 Autoconf + +Why does perl use a metaconfig-generated Configure script instead of an +autoconf-generated configure script? + +Metaconfig and autoconf are two tools with very similar purposes. +Metaconfig is actually the older of the two, and was originally written +by Larry Wall, while autoconf is probably now used in a wider variety of +packages. The autoconf info file discusses the history of autoconf and +how it came to be. The curious reader is referred there for further +information. + +Overall, both tools are quite good, I think, and the choice of which one +to use could be argued either way. In March, 1994, when I was just +starting to work on Configure support for Perl5, I considered both +autoconf and metaconfig, and eventually decided to use metaconfig for the +following reasons: + +=over 4 + +=item Compatibility with Perl4 + +Perl4 used metaconfig, so many of the #ifdef's were already set up for +metaconfig. Of course metaconfig had evolved some since Perl4's days, +but not so much that it posed any serious problems. + +=item Metaconfig worked for me + +My system at the time was Interactive 2.2, a SVR3.2/386 derivative that +also had some POSIX support. Metaconfig-generated Configure scripts +worked fine for me on that system. On the other hand, autoconf-generated +scripts usually didn't. (They did come quite close, though, in some +cases.) At the time, I actually fetched a large number of GNU packages +and checked. Not a single one configured and compiled correctly +out-of-the-box with the system's cc compiler. + +=item Configure can be interactive + +With both autoconf and metaconfig, if the script works, everything is +fine. However, one of my main problems with autoconf-generated scripts +was that if it guessed wrong about something, it could be B<very> hard to +go back and fix it. For example, autoconf always insisted on passing the +-Xp flag to cc (to turn on POSIX behavior), even when that wasn't what I +wanted or needed for that package. There was no way short of editing the +configure script to turn this off. You couldn't just edit the resulting +Makefile at the end because the -Xp flag influenced a number of other +configure tests. + +Metaconfig's Configure scripts, on the other hand, can be interactive. +Thus if Configure is guessing things incorrectly, you can go back and fix +them. This isn't as important now as it was when we were actively +developing Configure support for new features such as dynamic loading, +but it's still useful occasionally. + +=item GPL + +At the time, autoconf-generated scripts were covered under the GNU Public +License, and hence weren't suitable for inclusion with Perl, which has a +different licensing policy. (Autoconf's licensing has since changed.) + +=item Modularity + +Metaconfig builds up Configure from a collection of discrete pieces +called "units". You can override the standard behavior by supplying your +own unit. With autoconf, you have to patch the standard files instead. +I find the metaconfig "unit" method easier to work with. Others +may find metaconfig's units clumsy to work with. + +=back + +=head2 @INC search order + +By default, the list of perl library directories in @INC is the +following: + + $archlib + $privlib + $sitearch + $sitelib + +Specifically, on my Solaris/x86 system, I run +B<sh Configure -Dprefix=/opt/perl> and I have the following +directories: + + /opt/perl/lib/i86pc-solaris/5.00307 + /opt/perl/lib + /opt/perl/lib/site_perl/i86pc-solaris + /opt/perl/lib/site_perl + +That is, perl's directories come first, followed by the site-specific +directories. + +The site libraries come second to support the usage of extensions +across perl versions. Read the relevant section in F<INSTALL> for +more information. If we ever make $sitearch version-specific, this +topic could be revisited. + +=head2 Why isn't there a directory to override Perl's library? + +Mainly because no one's gotten around to making one. Note that +"making one" involves changing perl.c, Configure, config_h.SH (and +associated files, see above), and I<documenting> it all in the +INSTALL file. + +Apparently, most folks who want to override one of the standard library +files simply do it by overwriting the standard library files. + +=head2 APPLLIB + +In the perl.c sources, you'll find an undocumented APPLLIB_EXP +variable, sort of like PRIVLIB_EXP and ARCHLIB_EXP (which are +documented in config_h.SH). Here's what APPLLIB_EXP is for, from +a mail message from Larry: + + The main intent of APPLLIB_EXP is for folks who want to send out a + version of Perl embedded in their product. They would set the symbol + to be the name of the library containing the files needed to run or to + support their particular application. This works at the "override" + level to make sure they get their own versions of any library code that + they absolutely must have configuration control over. + + As such, I don't see any conflict with a sysadmin using it for a + override-ish sort of thing, when installing a generic Perl. It should + probably have been named something to do with overriding though. Since + it's undocumented we could still change it... :-) + +Given that it's already there, you can use it to override +distribution modules. If you do + + sh Configure -Dccflags='-DAPPLLIB_EXP=/my/override' + +then perl.c will put /my/override ahead of ARCHLIB and PRIVLIB. + +=head2 Shared libperl.so location + +Why isn't the shared libperl.so installed in /usr/lib/ along +with "all the other" shared libraries? Instead, it is installed +in $archlib, which is typically something like + + /usr/local/lib/perl5/archname/5.00404 + +and is architecture- and version-specific. + +The basic reason why a shared libperl.so gets put in $archlib is so that +you can have more than one version of perl on the system at the same time, +and have each refer to its own libperl.so. + +Three examples might help. All of these work now; none would work if you +put libperl.so in /usr/lib. + +=over + +=item 1. + +Suppose you want to have both threaded and non-threaded perl versions +around. Configure will name both perl libraries "libperl.so" (so that +you can link to them with -lperl). The perl binaries tell them apart +by having looking in the appropriate $archlib directories. + +=item 2. + +Suppose you have perl5.004_04 installed and you want to try to compile +it again, perhaps with different options or after applying a patch. +If you already have libperl.so installed in /usr/lib/, then it may be +either difficult or impossible to get ld.so to find the new libperl.so +that you're trying to build. If, instead, libperl.so is tucked away in +$archlib, then you can always just change $archlib in the current perl +you're trying to build so that ld.so won't find your old libperl.so. +(The INSTALL file suggests you do this when building a debugging perl.) + +=item 3. + +The shared perl library is not a "well-behaved" shared library with +proper major and minor version numbers, so you can't necessarily +have perl5.004_04 and perl5.004_05 installed simultaneously. Suppose +perl5.004_04 were to install /usr/lib/libperl.so.4.4, and perl5.004_05 +were to install /usr/lib/libperl.so.4.5. Now, when you try to run +perl5.004_04, ld.so might try to load libperl.so.4.5, since it has +the right "major version" number. If this works at all, it almost +certainly defeats the reason for keeping perl5.004_04 around. Worse, +with development subversions, you certaily can't guarantee that +libperl.so.4.4 and libperl.so.4.55 will be compatible. + +Anyway, all this leads to quite obscure failures that are sure to drive +casual users crazy. Even experienced users will get confused :-). Upon +reflection, I'd say leave libperl.so in $archlib. + +=back + +=head1 Upload Your Work to CPAN + +You can upload your work to CPAN if you have a CPAN id. Check out +http://www.perl.com/CPAN/modules/04pause.html for information on +_PAUSE_, the Perl Author's Upload Server. + +I typically upload both the patch file, e.g. F<perl5.004_08.pat.gz> +and the full tar file, e.g. F<perl5.004_08.tar.gz>. + +If you want your patch to appear in the F<src/5.0/unsupported> +directory on CPAN, send e-mail to the CPAN master librarian. (Check +out http://www.perl.com/CPAN/CPAN.html ). + +=head1 Help Save the World + +You should definitely announce your patch on the perl5-porters list. +You should also consider announcing your patch on +comp.lang.perl.announce, though you should make it quite clear that a +subversion is not a production release, and be prepared to deal with +people who will not read your disclaimer. + +=head1 Todo + +Here, in no particular order, are some Configure and build-related +items that merit consideration. This list isn't exhaustive, it's just +what I came up with off the top of my head. + +=head2 Good ideas waiting for round tuits + +=over 4 + +=item installprefix + +I think we ought to support + + Configure -Dinstallprefix=/blah/blah + +Currently, we support B<-Dprefix=/blah/blah>, but the changing the install +location has to be handled by something like the F<config.over> trick +described in F<INSTALL>. AFS users also are treated specially. +We should probably duplicate the metaconfig prefix stuff for an +install prefix. + +=item Configure -Dsrc=/blah/blah + +We should be able to emulate B<configure --srcdir>. Tom Tromey +tromey@creche.cygnus.com has submitted some patches to +the dist-users mailing list along these lines. They have been folded +back into the main distribution, but various parts of the perl +Configure/build/install process still assume src='.'. + +=item Hint file fixes + +Various hint files work around Configure problems. We ought to fix +Configure so that most of them aren't needed. + +=item Hint file information + +Some of the hint file information (particularly dynamic loading stuff) +ought to be fed back into the main metaconfig distribution. + +=item Catch GNU Libc "Stub" functions + +Some functions (such as lchown()) are present in libc, but are +unimplmented. That is, they always fail and set errno=ENOSYS. + +Thomas Bushnell provided the following sample code and the explanation +that follows: + + /* System header to define __stub macros and hopefully few prototypes, + which can conflict with char FOO(); below. */ + #include <assert.h> + /* Override any gcc2 internal prototype to avoid an error. */ + /* We use char because int might match the return type of a gcc2 + builtin and then its argument prototype would still apply. */ + char FOO(); + + int main() { + + /* The GNU C library defines this for functions which it implements + to always fail with ENOSYS. Some functions are actually named + something starting with __ and the normal name is an alias. */ + #if defined (__stub_FOO) || defined (__stub___FOO) + choke me + #else + FOO(); + #endif + + ; return 0; } + +The choice of <assert.h> is essentially arbitrary. The GNU libc +macros are found in <gnu/stubs.h>. You can include that file instead +of <assert.h> (which itself includes <gnu/stubs.h>) if you test for +its existence first. <assert.h> is assumed to exist on every system, +which is why it's used here. Any GNU libc header file will include +the stubs macros. If either __stub_NAME or __stub___NAME is defined, +then the function doesn't actually exist. Tests using <assert.h> work +on every system around. + +The declaration of FOO is there to override builtin prototypes for +ANSI C functions. + +=back + +=head2 Probably good ideas waiting for round tuits + +=over 4 + +=item GNU configure --options + +I've received sensible suggestions for --exec_prefix and other +GNU configure --options. It's not always obvious exactly what is +intended, but this merits investigation. + +=item make clean + +Currently, B<make clean> isn't all that useful, though +B<make realclean> and B<make distclean> are. This needs a bit of +thought and documentation before it gets cleaned up. + +=item Try gcc if cc fails + +Currently, we just give up. + +=item bypassing safe*alloc wrappers + +On some systems, it may be safe to call the system malloc directly +without going through the util.c safe* layers. (Such systems would +accept free(0), for example.) This might be a time-saver for systems +that already have a good malloc. (Recent Linux libc's apparently have +a nice malloc that is well-tuned for the system.) + +=back + +=head2 Vague possibilities + +=over 4 + +=item MacPerl + +Get some of the Macintosh stuff folded back into the main distribution. + +=item gconvert replacement + +Maybe include a replacement function that doesn't lose data in rare +cases of coercion between string and numerical values. + +=item Improve makedepend + +The current makedepend process is clunky and annoyingly slow, but it +works for most folks. Alas, it assumes that there is a filename +$firstmakefile that the B<make> command will try to use before it uses +F<Makefile>. Such may not be the case for all B<make> commands, +particularly those on non-Unix systems. + +Probably some variant of the BSD F<.depend> file will be useful. +We ought to check how other packages do this, if they do it at all. +We could probably pre-generate the dependencies (with the exception of +malloc.o, which could probably be determined at F<Makefile.SH> +extraction time. + +=item GNU Makefile standard targets + +GNU software generally has standardized Makefile targets.
