5 release_managers_guide - Releasing a new version of perl 5.x
7 Note that things change at each release, so there may be new things not
8 covered here, or tools may need updating.
10 =head1 MAKING A CHECKLIST
12 If you are preparing to do a release, you can run the
13 F<Porting/make-rmg-checklist> script to generate a new version of this
14 document that starts with a checklist for your release.
16 This script is run as:
18 perl Porting/make-rmg-checklist \
19 --version [5.x.y-RC#] > /tmp/rmg.pod
21 You can also pass the C<--html> flag to generate an HTML document instead of
24 perl Porting/make-rmg-checklist --html \
25 --version [5.x.y-RC#] > /tmp/rmg.html
29 This document describes the series of tasks required - some automatic, some
30 manual - to produce a perl release of some description, be that a release
31 candidate, or final, numbered release of maint or blead.
33 The release process has traditionally been executed by the current
34 pumpking. Blead releases from 5.11.0 forward are made each month on the
35 20th by a non-pumpking release engineer. The release engineer roster
36 and schedule can be found in Porting/release_schedule.pod.
38 This document both helps as a check-list for the release engineer
39 and is a base for ideas on how the various tasks could be automated
42 The checklist of a typical release cycle is as follows:
44 (5.10.1 is released, and post-release actions have been done)
48 a few weeks before the release, a number of steps are performed,
49 including bumping the version to 5.10.2
51 ...a few weeks pass...
53 perl-5.10.2-RC1 is released
55 perl-5.10.2 is released
57 post-release actions are performed, including creating new
60 ... the cycle continues ...
64 Some of the tasks described below apply to all four types of
65 release of Perl. (blead, RC, final release of maint, final
66 release of blead). Some of these tasks apply only to a subset
67 of these release types. If a step does not apply to a given
68 type of release, you will see a notation to that effect at
69 the beginning of the step.
75 =item Release Candidate (RC)
77 A release candidate is an attempt to produce a tarball that is a close as
78 possible to the final release. Indeed, unless critical faults are found
79 during the RC testing, the final release will be identical to the RC
80 barring a few minor fixups (updating the release date in F<perlhist.pod>,
81 removing the RC status from F<patchlevel.h>, etc). If faults are found,
82 then the fixes should be put into a new release candidate, never directly
86 =item Stable/Maint release (MAINT).
88 A release with an even version number, and subversion number > 0, such as
91 At this point you should have a working release candidate with few or no
94 It's essentially the same procedure as for making a release candidate, but
95 with a whole bunch of extra post-release steps.
97 Note that for a maint release there are two versions of this guide to
98 consider: the one in the maint branch, and the one in blead. Which one to
99 use is a fine judgement. The blead one will be most up-to-date, while
100 it might describe some steps or new tools that aren't applicable to older
101 maint branches. It is probably best to review both versions of this
102 document, but to most closely follow the steps in the maint version.
104 =item A blead point release (BLEAD-POINT)
106 A release with an odd version number, such as 5.15.0 or 5.15.1.
108 This isn't for production, so it has less stability requirements than for
109 other release types, and isn't preceded by RC releases. Other than that,
110 it is similar to a MAINT release.
112 =item Blead final release (BLEAD-FINAL)
114 A release with an even version number, and subversion number == 0, such as
115 5.14.0. That is to say, it's the big new release once per year.
117 It's essentially the same procedure as for making a release candidate, but
118 with a whole bunch of extra post-release steps, even more than for MAINT.
126 Before you can make an official release of perl, there are a few
127 hoops you need to jump through:
129 =head3 PAUSE account with pumpkin status
131 Make sure you have a PAUSE account suitable for uploading a perl release.
132 If you don't have a PAUSE account, then request one:
134 https://pause.perl.org/pause/query?ACTION=request_id
136 Check that your account is allowed to upload perl distros: go to
137 L<https://pause.perl.org/pause/authenquery?ACTION=who_pumpkin> and check that
138 your PAUSE ID is listed there. If not, ask Andreas KE<0xf6>nig to add your ID
139 to the list of people allowed to upload something called perl. You can find
140 Andreas' email address at:
142 https://pause.perl.org/pause/query?ACTION=pause_04imprint
144 =head3 GitHub issue management access
146 Make sure you have permission to close tickets on L<https://github.com/Perl/perl5/issues>
147 so you can respond to bug reports as necessary during your stint. If you
148 don't, make a GitHub account (if you don't have one) and contact the pumpking
149 with your username to get ticket-closing permission.
151 =head3 git checkout and commit bit
153 You will need a working C<git> installation, checkout of the perl
154 git repository and perl commit bit. For information about working
155 with perl and git, see F<pod/perlgit.pod>.
157 If you are not yet a perl committer, you won't be able to make a
158 release. Have a chat with whichever evil perl porter tried to talk
159 you into the idea in the first place to figure out the best way to
162 =head3 web-based file share
164 You will need to be able to share tarballs with #p5p members for
165 pre-release testing, and you may wish to upload to PAUSE via URL.
166 Make sure you have a way of sharing files, such as a web server or
167 file-sharing service.
169 Porters have access to the "dromedary" server (users.perl5.git.perl.org),
170 which has a F<public_html> directory to share files with.
171 (L<http://users.perl5.git.perl.org/~username/perl-5.xx.y.tar.gz>)
173 If you use Dropbox, you can append "raw=1" as a parameter to their usual
174 sharing link to allow direct download (albeit with redirects).
176 =head3 Quotation for release announcement epigraph
178 You will need a quotation to use as an epigraph to your release announcement.
179 It will live forever (along with Perl), so make it a good one.
181 =head3 Install the previous version of perl
183 During the testing phase of the release you have created, you will be
184 asked to compare the installed files with a previous install. Save yourself
185 some time on release day, and have a (clean) install of the previous
188 =head2 Building a release - advance actions
190 The work of building a release candidate for an even numbered release
191 (BLEAD-FINAL) of perl generally starts several weeks before the first
192 release candidate. Some of the following steps should be done regularly,
193 but all I<must> be done in the run up to a release.
195 =head3 dual-life CPAN module synchronisation
197 To see which core distro versions differ from the current CPAN versions:
199 $ ./perl -Ilib Porting/core-cpan-diff -x -a
201 However, this only checks whether the version recorded in
202 F<Porting/Maintainers.pl> differs from the latest on CPAN. It doesn't tell you
203 if the code itself has diverged from CPAN.
205 You can also run an actual diff of the contents of the modules, comparing core
206 to CPAN, to ensure that there were no erroneous/extraneous changes that need to
207 be dealt with. You do this by not passing the C<-x> option:
209 $ ./perl -Ilib Porting/core-cpan-diff -a -o ~/corediffs
211 Passing C<-u cpan> will probably be helpful, since it limits the search to
212 distributions with 'cpan' upstream source. (It's OK for blead upstream to
213 differ from CPAN because those dual-life releases usually come I<after> perl
216 See also the C<-d> and C<-v> options for more detail (and the C<-u> option as
217 mentioned above). You'll probably want to use the C<-c cachedir> option to
218 avoid repeated CPAN downloads and may want to use C<-m file:///mirror/path> if
219 you made a local CPAN mirror. Note that a minicpan mirror won't actually work,
220 but can provide a good first pass to quickly get a list of modules which
221 definitely haven't changed, to avoid having to download absolutely everything.
223 For a BLEAD-POINT or BLEAD-FINAL release with 'cpan' upstream, if a CPAN
224 release appears to be ahead of blead, then consider updating it (or asking the
225 relevant porter to do so). (However, if this is a BLEAD-FINAL release or one of
226 the last BLEAD-POINT releases before it and hence blead is in some kind of
227 "code freeze" state (e.g. the sequence might be "contentious changes freeze",
228 then "user-visible changes freeze" and finally "full code freeze") then any
229 CPAN module updates must be subject to the same restrictions, so it may not be
230 possible to update all modules until after the BLEAD-FINAL release.) If blead
231 contains edits to a 'cpan' upstream module, this is naughty but sometimes
232 unavoidable to keep blead tests passing. Make sure the affected file has a
233 CUSTOMIZED entry in F<Porting/Maintainers.pl>.
235 If you are making a MAINT release, run C<core-cpan-diff> on both blead and
236 maint, then diff the two outputs. Compare this with what you expect, and if
237 necessary, fix things up. For example, you might think that both blead
238 and maint are synchronised with a particular CPAN module, but one might
239 have some extra changes.
241 In any case, any cpan-first distribution that is listed as having files
242 "Customized for blead" in the output of cpan-core-diff should have requests
243 submitted to the maintainer(s) to make a cpan release to catch up with blead.
245 Additionally, all files listed as "modified" but not "customized for blead"
246 should have entries added under the C<CUSTOMIZED> key in
247 F<Porting/Maintainers.pl>, as well as checksums updated via:
249 cd t; ../perl -I../lib porting/customized.t --regen
251 =head4 Sync CPAN modules with the corresponding cpanE<sol> distro
253 In most cases, once a new version of a distribution shipped with core has been
254 uploaded to CPAN, the core version thereof can be synchronized automatically
255 with the program F<Porting/sync-with-cpan>. (But see the comments at the
256 beginning of that program. In particular, it has not yet been exercised on
257 Windows as much as it has on Unix-like platforms.)
259 If, however, F<Porting/sync-with-cpan> does not provide good results, follow
266 Fetch the most recent version from CPAN.
270 Unpack the retrieved tarball. Rename the old directory; rename the new
271 directory to the original name.
275 Restore any F<.gitignore> file. This can be done by issuing
276 C<git checkout .gitignore> in the F<cpan/Distro> directory.
280 Remove files we do not need. That is, remove any files that match the
281 entries in C<@IGNORABLE> in F<Porting/Maintainers.pl>, and anything that
282 matches the C<EXCLUDED> section of the distro's entry in the C<%Modules>
287 Restore any files mentioned in the C<CUSTOMIZED> section, using
288 C<git checkout>. Make any new customizations if necessary. Also,
289 restore any files that are mentioned in C<@IGNORE>, but were checked
290 into the repository anyway.
294 For any new files in the distro, determine whether they are needed.
295 If not, delete them, and list them in either C<EXCLUDED> or C<@IGNORABLE>.
296 Otherwise, add them to C<MANIFEST>, and run C<git add> to add the files
301 For any files that are gone, remove them from C<MANIFEST>, and use
302 C<git rm> to tell git the files will be gone.
306 If the C<MANIFEST> file was changed in any of the previous steps, run
307 C<perl Porting/manisort --output MANIFEST.sort; mv MANIFEST.sort MANIFEST>.
311 For any files that have an execute bit set, either remove the execute
312 bit, or edit F<Porting/exec-bit.txt>
316 Run C<make> (or C<nmake> on Windows), see if C<perl> compiles.
320 Run the tests for the package.
324 Run the tests in F<t/porting> (C<make test_porting>).
328 Update the C<DISTRIBUTION> entry in F<Porting/Maintainers.pl>.
332 Run a full configure/build/test cycle.
336 If everything is ok, commit the changes.
340 For entries with a non-simple C<FILES> section, or with a C<MAP>, you
341 may have to take more steps than listed above.
343 =head3 Ensure dual-life CPAN module stability
347 for each module that fails its regression tests on $current
348 did it fail identically on $previous?
349 if yes, "SEP" (Somebody Else's Problem, but try to make sure a
351 else work out why it failed (a bisect is useful for this)
353 attempt to group failure causes
355 for each failure cause
356 is that a regression?
357 if yes, figure out how to fix it
358 (more code? revert the code that broke it)
360 (presumably) it's relying on something un-or-under-documented
361 should the existing behaviour stay?
362 yes - goto "regression"
363 no - note it in perldelta as a significant bugfix
364 (also, try to inform the module's author)
366 =head3 monitor smoke tests for failures
368 Similarly, monitor the smoking of core tests, and try to fix. See
369 L<https://tux.nl/perl5/smoke/index.html>, L<https://perl5.test-smoke.org/>
370 and L<http://perl.develop-help.com> for a summary. See also
371 L<https://www.nntp.perl.org/group/perl.daily-build.reports/> which has
374 Similarly, monitor the smoking of perl for compiler warnings, and try to
377 =for checklist skip BLEAD-POINT
379 =head3 monitor CPAN testers for failures
381 For any release except a BLEAD-POINT: Examine the relevant analysis report(s)
382 at L<http://analysis.cpantesters.org/beforemaintrelease> to see how the
383 impending release is performing compared to previous releases with
384 regard to building and testing CPAN modules.
386 That page accepts a query parameter, C<pair> that takes a pair of
387 colon-delimited versions to use for comparison. For example:
389 L<http://analysis.cpantesters.org/beforemaintrelease?pair=5.20.2:5.22.0%20RC1>
391 =head3 Monitor Continuous Integration smokers
393 Currently both "Travis CI" and "GitHub Actions" smokers are setup.
394 Their current status is available at:
396 L<https://github.com/Perl/perl5/actions>
397 L<https://travis-ci.org/Perl/perl5>
399 =head3 update perldelta
401 Get perldelta in a mostly finished state.
403 Read F<Porting/how_to_write_a_perldelta.pod>, and try to make sure that
404 every section it lists is, if necessary, populated and complete. Copy
405 edit the whole document.
407 You won't be able to automatically fill in the "Updated Modules" section until
408 after Module::CoreList is updated (as described below in
409 L<"update Module::CoreList">).
411 =head3 Bump the version number
413 Do not do this yet for a BLEAD-POINT release! You will do this at the end of
414 the release process (after building the final tarball, tagging etc).
416 Increase the version number (e.g. from 5.12.0 to 5.12.1).
418 For a release candidate for a stable perl, this should happen a week or two
419 before the first release candidate to allow sufficient time for testing and
420 smoking with the target version built into the perl executable. For
421 subsequent release candidates and the final release, it is not necessary to
422 bump the version further.
424 There is a tool to semi-automate this process:
426 $ ./perl -Ilib Porting/bump-perl-version -i 5.10.0 5.10.1
428 Remember that this tool is largely just grepping for '5.10.0' or whatever,
429 so it will generate false positives. Be careful not change text like
430 "this was fixed in 5.10.0"!
432 Use git status and git diff to select changes you want to keep.
434 Be particularly careful with F<INSTALL>, which contains a mixture of
435 C<5.10.0>-type strings, some of which need bumping on every release, and
436 some of which need to be left unchanged.
437 See below in L<"update INSTALL"> for more details.
439 For the first RC release leading up to a BLEAD-FINAL release, update the
440 description of which releases are now "officially" supported in
441 F<pod/perlpolicy.pod>.
443 When doing a BLEAD-POINT or BLEAD-FINAL release, also make sure the
444 C<PERL_API_*> constants in F<patchlevel.h> are in sync with the version
445 you're releasing, unless you're absolutely sure the release you're about to
446 make is 100% binary compatible to an earlier release. Note: for BLEAD-POINT
447 releases the bump should have already occurred at the end of the previous
448 release and this is something you would have to do at the very end.
449 When releasing a MAINT perl version, the C<PERL_API_*> constants C<MUST NOT>
450 be changed as we aim to guarantee binary compatibility in maint branches.
452 After editing, regenerate uconfig.h (this must be run on a system with a
455 $ perl regen/uconfig_h.pl
457 This might not cause any new changes.
459 You may also need to regen opcodes:
461 $ ./perl -Ilib regen/opcode.pl
465 $ git clean -xdf # careful if you don't have local files to keep!
466 $ ./Configure -des -Dusedevel
470 Do note that at this stage, porting tests will fail. They will continue
471 to fail until you've updated Module::CoreList, as described below.
477 B<review the delta carefully>
479 $ git commit -a -m 'Bump the perl version in various places for 5.x.y'
481 At this point you may want to compare the commit with a previous bump to
482 see if they look similar. See commit f7cf42bb69 for an example of a
483 previous version bump.
485 When the version number is bumped, you should also update Module::CoreList
486 (as described below in L<"update Module::CoreList">) to reflect the new
489 =head3 update INSTALL
491 Review and update INSTALL to account for the change in version number.
492 INSTALL for a BLEAD-POINT release should already contain the expected version.
493 The lines in F<INSTALL> about "is not binary compatible with" may require a
494 correct choice of earlier version to declare incompatibility with. These are
495 in the "Changes and Incompatibilities" and "Coexistence with earlier versions
498 Be particularly careful with the section "Upgrading from 5.X.Y or earlier".
499 The "X.Y" needs to be changed to the most recent version that we are
500 I<not> binary compatible with.
502 For MAINT and BLEAD-FINAL releases, this needs to refer to the last
503 release in the previous development cycle (so for example, for a 5.14.x
504 release, this would be 5.13.11).
506 For BLEAD-POINT releases, it needs to refer to the previous BLEAD-POINT
507 release (so for 5.15.3 this would be 5.15.2). If the last release manager
508 followed instructions, this should have already been done after the last
509 blead release, so you may find nothing to do here.
511 =head3 update AUTHORS
513 The AUTHORS file can be updated by running C<Porting/checkAUTHORS.pl --update>
514 The script detects missing authors or committers since the last release using
515 a known tag provided by the C<--from=v5.X.Y> argument, and will add missing
516 entries to the AUTHORS file.
518 $ perl Porting/checkAUTHORS.pl --update --from=v5.X.Y
520 For MAINT and BLEAD-FINAL releases, C<v5.X.Y> needs to refer to the last
521 release in the previous development cycle (so for example, for a 5.14.x
522 release, this would be 5.13.11).
524 For BLEAD-POINT releases, it needs to refer to the previous BLEAD-POINT
525 release (so for 5.15.3 this would be 5.15.2).
527 Note: It should not be harmful to use a wider range.
529 Note: If you have uncommitted changes this could cause some warnings,
530 and you might like to use the addtional argument C<--to=upstream/blead>
531 to use the last known git commit by GitHub.
533 Review the changes to the AUTHORS file, be sure you are not adding duplicate
534 entries or removing any entries, then commit your changes.
536 $ git commit -a AUTHORS -m 'Update AUTHORS list for 5.x.y'
538 =head3 Check copyright years
540 Check that the copyright years are up to date by running:
542 $ pushd t; ../perl -I../lib porting/copyright.t --now
544 Remedy any test failures by editing README or perl.c accordingly (search for
545 the "Copyright"). If updating perl.c, check if the file's own copyright date in
546 the C comment at the top needs updating, as well as the one printed by C<-v>.
548 =head3 Check more build configurations
550 Try running the full test suite against multiple Perl configurations. Here are
551 some sets of Configure flags you can try:
557 C<-Duseshrplib -Dusesitecustomize>
561 C<-Duserelocatableinc>
569 If you have multiple compilers on your machine, you might also consider
570 compiling with C<-Dcc=$other_compiler>.
572 You can also consider pushing the repo to GitHub where Travis CI is enabled
573 which would smoke different flavors of Perl for you.
575 =head3 update perlport
577 L<perlport> has a section currently named I<Supported Platforms> that
578 indicates which platforms are known to build in the current release.
579 If necessary update the list and the indicated version number.
581 =head3 check a readonly build
583 Even before other prep work, follow the steps in L</build the tarball> and test
584 it locally. Because a perl source tarballs sets many files read-only, it could
585 test differently than tests run from the repository. After you're sure
586 permissions aren't a problem, delete the generated directory and tarballs.
589 =head2 Building a release - on the day
591 This section describes the actions required to make a release
592 that are performed near to, or on the actual release day.
594 =head3 re-check earlier actions
596 Review all the actions in the previous section,
597 L<"Building a release - advance actions"> to ensure they are all done and
600 =head3 create a release branch
602 For BLEAD-POINT releases, making a release from a release branch avoids the
603 need to freeze blead during the release. This is less important for
604 BLEAD-FINAL, MAINT, and RC releases, since blead will already be frozen in
605 those cases. Create the branch by running
607 git checkout -b release-5.xx.yy
609 =head3 build a clean perl
611 Make sure you have a gitwise-clean perl directory (no modified files,
612 unpushed commits etc):
617 then configure and build perl so that you have a Makefile and porting tools:
619 $ ./Configure -Dusedevel -des && make
621 =head3 Check module versions
623 For each Perl release since the previous release of the current branch, check
624 for modules that have identical version numbers but different contents by
627 $ ./perl -Ilib Porting/cmpVERSION.pl --tag=v5.X.YY
629 (This is done automatically by F<t/porting/cmp_version.t> for the previous
630 release of the current branch, but not for any releases from other branches.)
632 Any modules that fail will need a version bump, plus a nudge to the upstream
633 maintainer for 'cpan' upstream modules.
635 =head3 update Module::CoreList
637 =head4 Bump Module::CoreList* $VERSIONs
639 If necessary, bump C<$VERSION> (there's no need to do this
640 for every RC; in RC1, bump the version to a new clean number that will
641 appear in the final release, and leave as-is for the later RCs and final).
642 It may also happen that C<Module::CoreList> has been modified in blead, and
643 hence has a new version number already. (But make sure it is not the same
644 number as a CPAN release.)
646 C<$Module::CoreList::Utils::VERSION> should always be equal to
647 C<$Module::CoreList::VERSION>. If necessary, bump those two versions to match
650 Once again, the files to modify are:
656 F<dist/Module-CoreList/lib/Module/CoreList.pm>
660 F<dist/Module-CoreList/lib/Module/CoreList/Utils.pm>
664 =head4 Update C<Module::CoreList> with module version data for the new release.
666 Note that if this is a MAINT release, you should run the following actions
667 from the maint branch, but commit the C<CoreList.pm> changes in
668 I<blead> and subsequently cherry-pick any releases since the last
669 maint release and then your recent commit. XXX need a better example
671 [ Note that the procedure for handling Module::CoreList in maint branches
672 is a bit complex, and the RMG currently don't describe a full and
673 workable approach. The main issue is keeping Module::CoreList
674 and its version number synchronised across all maint branches, blead and
675 CPAN, while having to bump its version number for every RC release.
676 See this brief p5p thread:
678 Message-ID: <20130311174402.GZ2294@iabyn.com>
680 If you can devise a workable system, feel free to try it out, and to
681 update the RMG accordingly!
685 F<corelist.pl> uses ftp.funet.fi to verify information about dual-lived
686 modules on CPAN. It can use a full, local CPAN mirror and/or fall back
687 on HTTP::Tiny to fetch package metadata remotely.
689 (If you'd prefer to have a full CPAN mirror, see
690 L<https://www.cpan.org/misc/cpan-faq.html#How_mirror_CPAN>)
692 Change to your perl checkout, and if necessary,
696 Then, If you have a local CPAN mirror, run:

704 This will chug for a while, possibly reporting various warnings about
705 badly-indexed CPAN modules unrelated to the modules actually in core.
706 Assuming all goes well, it will update
707 F<dist/Module-CoreList/lib/Module/CoreList.pm> and possibly
708 F<dist/Module-CoreList/lib/Module/CoreList/Utils.pm>.
710 Check those files over carefully:

713 $ git diff dist/Module-CoreList/lib/Module/CoreList/Utils.pm
715 =head4 Bump version in Module::CoreList F<Changes>
717 Also edit Module::CoreList's new version number in its F<Changes> file.
718 This file is F<dist/Module-CoreList/Changes>.
719 (BLEAD-POINT releases should have had this done already as a post-release
720 action from the last commit.)
722 =head4 Add Module::CoreList version bump to perldelta
724 Add a perldelta entry for the new Module::CoreList version. You only
725 need to do this if you want to add notes about the changes included
726 with this version of Module::CoreList. Otherwise, its version bump
727 will be automatically filled in below in L</finalize perldelta>.
729 =for checklist skip RC
731 =head4 Update C<%Module::CoreList::released>
733 For any release except an RC: Update this version's entry in the C<%released>
734 hash with today's date.
736 =head4 Commit Module::CoreList changes
738 Finally, commit the new version of Module::CoreList:
739 (unless this is for MAINT; in which case commit it to blead first, then
740 cherry-pick it back).
742 $ git commit -m 'Update Module::CoreList for 5.x.y' \
743 dist/Module-CoreList/Changes \
744 dist/Module-CoreList/lib/Module/CoreList.pm \
745 dist/Module-CoreList/lib/Module/CoreList/Utils.pm
747 =head4 Rebuild and test
749 Build and test to get the changes into the currently built lib directory and to
750 ensure all tests are passing.
752 =head3 finalize perldelta
754 Finalize the perldelta. In particular, fill in the Acknowledgements
755 section, which can be generated with something like:
757 $ perl Porting/acknowledgements.pl v5.15.0..HEAD
759 Fill in the "New/Updated Modules" sections now that Module::CoreList is
762 $ ./perl -Ilib Porting/corelist-perldelta.pl \
763 --mode=update pod/perldelta.pod
765 For a MAINT release use something like this instead:
767 $ ./perl -Ilib Porting/corelist-perldelta.pl 5.020001 5.020002 \
768 --mode=update pod/perldelta.pod
770 Ideally, also fill in a summary of the major changes to each module for which
771 an entry has been added by F<corelist-perldelta.pl>.
773 Re-read the perldelta to try to find any embarrassing typos and thinkos;
774 remove any C<TODO> or C<XXX> flags; update the "Known Problems" section
775 with any serious issues for which fixes are not going to happen now; and
776 run through pod and spell checkers, e.g.
778 $ podchecker -warnings -warnings pod/perldelta.pod
779 $ spell pod/perldelta.pod
780 $ aspell list < pod/perldelta.pod | sort -u
782 Also, you may want to generate and view an HTML version of it to check
785 $ ./perl -Ilib ext/Pod-Html/bin/pod2html pod/perldelta.pod > \
788 You should add pod links for GitHub issue references thusly:
790 $ perl -p -i -e'BEGIN{undef $/}; s{(GH\s+#)(\d+)}{L<$1$2|https://github.com/Perl/perl5/issues/$2>}mg' pod/perldelta.pod
792 If you make changes, be sure to commit them.
794 =for checklist skip BLEAD-POINT MAINT RC
796 =head3 remove stale perldeltas
798 For the first RC release that is ONLY for a BLEAD-FINAL, the perldeltas
799 from the BLEAD-POINT releases since the previous BLEAD-FINAL should have
800 now been consolidated into the current perldelta, and hence are now just
801 useless clutter. They can be removed using:
803 $ git rm <file1> <file2> ...
805 For example, for RC0 of 5.16.0:
808 $ git rm perldelta515*.pod
810 =for checklist skip BLEAD-FINAL BLEAD-POINT
812 =head3 add recent perldeltas
814 For the first RC for a MAINT release, copy in any recent perldeltas from
815 blead that have been added since the last release on this branch. This
816 should include any recent maint releases on branches older than your one,
817 but not newer. For example if you're producing a 5.14.x release, copy any
818 perldeltas from recent 5.10.x, 5.12.x etc maint releases, but not from
819 5.16.x or higher. Remember to
821 $ git add <file1> <file2> ...
823 =head3 update and commit perldelta files
825 If you have added or removed any perldelta files via the previous two
826 steps, then edit F<pod/perl.pod> to add/remove them from its table of
827 contents, then run F<Porting/pod_rules.pl> to propagate your changes there
828 into all the other files that mention them (including F<MANIFEST>). You'll
829 need to C<git add> the files that it changes.
831 Then build a clean perl and do a full test
835 $ ./Configure -Dusedevel -des
839 Once all tests pass, commit your changes.
841 =head3 final check of perldelta placeholders
843 Check for any 'XXX' leftover section in the perldelta.
844 Either fill them or remove these sections appropriately.
846 $ git grep XX pod/perldelta.pod
848 =head3 build a clean perl
850 If you skipped the previous step (adding/removing perldeltas),
851 again, make sure you have a gitwise-clean perl directory (no modified files,
852 unpushed commits etc):
857 then configure and build perl so that you have a Makefile and porting tools:
859 $ ./Configure -Dusedevel -des && make
861 =for checklist skip BLEAD-FINAL BLEAD-POINT
863 =head3 synchronise from blead's perlhist.pod
865 For the first RC for a MAINT release, copy in the latest
866 F<pod/perlhist.pod> from blead; this will include details of newer
867 releases in all branches. In theory, blead's version should be a strict
868 superset of the one in this branch, but it's probably safest to examine the
869 changes first, to ensure that there's nothing in this branch that was
870 forgotten from blead. An easy way to do that is with C<< git checkout -p >>,
871 to selectively apply any changes from the blead version to your current
875 $ git checkout -p origin/blead pod/perlhist.pod
876 $ git commit -m 'sync perlhist from blead' pod/perlhist.pod
878 =head3 update perlhist.pod
880 Add an entry to F<pod/perlhist.pod> with the release date, e.g.:
882 David 5.10.1 2009-Aug-06
884 List yourself in the left-hand column, and if this is the first release
885 that you've ever done, make sure that your name is listed in the section
886 entitled C<THE KEEPERS OF THE PUMPKIN>.
888 I<If you're making a BLEAD-FINAL release>, also update the "SELECTED
889 RELEASE SIZES" section with the output of
890 F<Porting/perlhist_calculate.pl>.
892 Be sure to commit your changes:

896 =for checklist skip BLEAD-POINT
898 =head3 update patchlevel.h
900 I<You MUST SKIP this step for a BLEAD-POINT release>
902 Update F<patchlevel.h> to add a C<-RC1>-or-whatever string; or, if this is
903 a final release, remove it. For example:
905 static const char * const local_patches[] = {
908 #ifdef PERL_GIT_UNCOMMITTED_CHANGES
909 ,"uncommitted-changes"
912 Be sure to commit your change:
914 $ git commit -m 'bump version to RCnnn' patchlevel.h
916 =head3 run makemeta to update META files
918 $ ./perl -Ilib Porting/makemeta
920 Be sure to commit any changes (if applicable):
922 $ git status # any changes?
923 $ git commit -m 'Update META files' META.*
925 =head3 build, test and check a fresh perl
927 Build perl, then make sure it passes its own test suite, and installs:
930 $ ./Configure -des -Dprefix=/tmp/perl-5.x.y-pretest
932 # or if it's an odd-numbered version:
933 $ ./Configure -des -Dusedevel -Dprefix=/tmp/perl-5.x.y-pretest
937 Check that the output of C</tmp/perl-5.x.y-pretest/bin/perl -v> and
938 C</tmp/perl-5.x.y-pretest/bin/perl -V> are as expected,
939 especially as regards version numbers, patch and/or RC levels, and @INC
940 paths. Note that as they have been built from a git working
941 directory, they will still identify themselves using git tags and
942 commits. (Note that for an odd-numbered version, perl will install
943 itself as C<perl5.x.y>). C<perl -v> will identify itself as:
945 This is perl 5, version X, subversion Y (v5.X.Y (v5.X.Z-NNN-gdeadbeef))
947 where 5.X.Z is the latest tag, NNN the number of commits since this tag,
948 and C<< deadbeef >> commit of that tag.
950 Then delete the temporary installation.
952 =head3 create the release tag
954 Create the tag identifying this release (e.g.):
956 $ git tag v5.11.0 -m 'First release of the v5.11 series!'
958 It is B<VERY> important that from this point forward, you not push
959 your git changes to the Perl master repository. If anything goes
960 wrong before you publish your newly-created tag, you can delete
961 and recreate it. Once you push your tag, we're stuck with it
962 and you'll need to use a new version number for your release.
964 =head3 build the tarball
966 Before you run the following, you might want to install 7-Zip (the
967 C<p7zip-full> package under Debian or the C<p7zip> port on MacPorts) or
968 the AdvanceCOMP suite (e.g. the C<advancecomp> package under Debian,
969 or the C<advancecomp> port on macports - 7-Zip on Windows is the
970 same code as AdvanceCOMP, so Windows users get the smallest files
971 first time). These compress about 5% smaller than gzip and bzip2.
972 Over the lifetime of your distribution this will save a lot of
973 people a small amount of download time and disk space, which adds
976 In order to produce the C<xz> tarball, XZ Utils are required. The C<xz>
977 utility is included with most modern UNIX-type operating systems and
978 is available for Cygwin. A Windows port is available from
979 L<https://tukaani.org/xz/>.
981 B<IMPORTANT>: if you are on OS X, you must export C<COPYFILE_DISABLE=1>
982 to prevent OS X resource files from being included in your tarball. After
983 creating the tarball following the instructions below, inspect it to ensure
984 you don't have files like F<._foobar>.
986 Create a tarball. Use the C<-s> option to specify a suitable suffix for
987 the tarball and directory name:
989 $ cd root/of/perl/tree
990 $ make distclean # make sure distclean works
991 $ git clean -xdf # make sure perl and git agree on files
992 # git clean should not output anything!
993 $ git status --ignored # and there's nothing lying around
995 $ perl Porting/makerel -x -s RC1 # for a release candidate
996 $ perl Porting/makerel -x # for the release itself
998 This creates the directory F<../perl-x.y.z-RC1> or similar, copies all
999 the MANIFEST files into it, sets the correct permissions on them, then
1000 tars it up as F<../perl-x.y.z-RC1.tar.gz>. The C<-x> also produces a
1003 If you're getting your tarball suffixed with -uncommitted and you're sure
1004 your changes were all committed, you can override the suffix with:
1006 $ perl Porting/makerel -x -s ''
1008 XXX if we go for extra tags and branches stuff, then add the extra details
1011 Finally, clean up the temporary directory, e.g.
1013 $ rm -rf ../perl-x.y.z-RC1
1015 =head3 test the tarball
1017 Once you have a tarball it's time to test the tarball (not the repository).
1019 =head4 Copy the tarball to a web server
1021 Copy the tarballs (.gz and .xz) to a web server somewhere you have access to.
1023 =head4 Download the tarball to another machine and unpack it
1025 Download the tarball to some other machine. For a release candidate,
1026 you really want to test your tarball on two or more different platforms
1029 =head4 Ask #p5p to test the tarball on different platforms
1031 Once you've verified the tarball can be downloaded and unpacked,
1032 ask the #p5p IRC channel on irc.perl.org for volunteers to test the
1033 tarballs on whatever platforms they can.
1035 If you're not confident in the tarball, you can defer this step until after
1036 your own tarball testing, below.
1038 =head4 Check that F<Configure> works
1040 Check that basic configuration and tests work on each test machine:
1042 $ ./Configure -des && make all minitest test
1044 # Or for a development release:
1045 $ ./Configure -Dusedevel -des && make all minitest test
1047 =head4 Run the test harness and install
1049 Check that the test harness and install work on each test machine:
1052 $ ./Configure -des -Dprefix=/install/path && \
1053 make all test_harness install
1056 (Remember C<-Dusedevel> above, for a development release.)
1058 =head4 Check C<perl -v> and C<perl -V>
1060 Check that the output of C<perl -v> and C<perl -V> are as expected,
1061 especially as regards version numbers, patch and/or RC levels, and @INC
1064 Note that the results may be different without a F<.git/> directory,
1065 which is why you should test from the tarball.
1067 =head4 Run the Installation Verification Procedure utility
1069 $ ./perl -Ilib ./utils/perlivp
1071 $ ./perl5.x.y ./utils/perlivp5.x.y
1073 All tests successful.
1076 =head4 Compare the installed paths to the last release
1078 Compare the pathnames of all installed files with those of the previous
1079 release (i.e. against the last installed tarball on this branch which you
1080 have previously verified using this same procedure). In particular, look
1081 for files in the wrong place, or files no longer included which should be.
1082 For example, suppose the about-to-be-released version is 5.10.1 and the
1085 cd installdir-5.10.0/
1086 find . -type f | perl -pe's/5\.10\.0/5.10.1/g' | sort > /tmp/f1
1087 cd installdir-5.10.1/
1088 find . -type f | sort > /tmp/f2
1091 =head4 Disable C<local::lib> if it's turned on
1093 If you're using C<local::lib>, you should reset your environment before
1094 performing these actions:
1096 $ unset PERL5LIB PERL_MB_OPT PERL_LOCAL_LIB_ROOT PERL_MM_OPT
1098 =head4 Bootstrap the CPAN client
1100 Bootstrap the CPAN client on the clean install:
1107 =head4 Install the Inline module with CPAN and test it
1109 Try installing a popular CPAN module that's reasonably complex and that
1110 has dependencies; for example:
1112 CPAN> install Inline::C
1115 Check that your perl can run this:
1117 $ bin/perl -Ilib -lwe "use Inline C => q[int f() { return 42;}]; print f"
1121 =head4 Make sure that perlbug works
1123 Test L<perlbug> with the following:
1127 Subject: test bug report
1128 Local perl administrator [yourself]:
1134 Action (Send/Display/Edit/Subject/Save to File): f
1135 Name of file to save message in [perlbug.rep]:
1136 Action (Send/Display/Edit/Subject/Save to File): Q
1138 and carefully examine the output (in F<perlbug.rep]>), especially
1139 the "Locally applied patches" section.
1141 =for checklist skip BLEAD-POINT
1143 =head3 monitor smokes
1145 XXX This is probably irrelevant if working on a release branch, though
1146 MAINT or RC might want to push a smoke branch and wait.
1148 Wait for the smoke tests to catch up with the commit which this release is
1149 based on (or at least the last commit of any consequence).
1151 Then check that the smoke tests pass (particularly on Win32). If not, go
1152 back and fix things.
1154 Note that for I<BLEAD-POINT> releases this may not be practical. It takes a
1155 long time for the smokers to catch up, especially the Win32
1156 smokers. This is why we have a RC cycle for I<MAINT> and I<BLEAD-FINAL>
1157 releases, but for I<BLEAD-POINT> releases sometimes the best you can do is
1158 to plead with people on IRC to test stuff on their platforms, fire away,
1159 and then hope for the best.
1161 =head3 upload to PAUSE
1163 Once smoking is okay, upload it to PAUSE. This is the point of no return.
1164 If anything goes wrong after this point, you will need to re-prepare
1165 a new release with a new minor version or RC number.
1167 https://pause.perl.org/
1169 (Log in, then select 'Upload a file to CPAN')
1171 If your workstation is not connected to a high-bandwidth,
1172 high-reliability connection to the Internet, you should probably use the
1173 "GET URL" feature (rather than "HTTP UPLOAD") to have PAUSE retrieve the
1174 new release from wherever you put it for testers to find it. This will
1175 eliminate anxious gnashing of teeth while you wait to see if your
1176 15 megabyte HTTP upload successfully completes across your slow, twitchy
1179 You can make use of your home directory on dromedary for
1180 this purpose: F<http://users.perl5.git.perl.org/~USERNAME> maps to
1181 F</home/USERNAME/public_html>, where F<USERNAME> is your login account
1184 I<Remember>: if your upload is partially successful, you
1185 may need to contact a PAUSE administrator or even bump the version of perl.
1187 Upload the .gz and .xz versions of the tarball.
1189 Note: You can also use the command-line utility to upload your tarballs, if
1190 you have it configured:
1192 cpan-upload perl-5.X.Y.tar.gz
1193 cpan-upload perl-5.X.Y.tar.xz
1195 Do not proceed any further until you are sure that your tarballs are on CPAN.

1207 Wait until you receive notification emails from the PAUSE indexer
1208 confirming that your uploads have been received. IMPORTANT -- you will
1209 probably get an email that indexing has failed, due to module permissions.
1210 This is considered normal.

1238 Send a carbon copy to C<noc@metacpan.org>

1242 Merge the (local) release branch back into master now, and delete it.
1246 git merge release-5.xx.yy
1248 git branch -d release-5.xx.yy
1250 Note: The merge will create a merge commit if other changes have been pushed
1251 to blead while you've been working on your release branch. Do NOT rebase your
1252 branch to avoid the merge commit (as you might normally do when merging a
1253 small branch into blead) since doing so will invalidate the tag that you

1342 previous version bump.
1344 =for checklist skip MAINT RC
1348 I<You MUST SKIP this step for RC and MAINT>
1350 If this was a BLEAD-FINAL release (i.e. the first release of a new maint
1351 series, 5.x.0 where x is even), then bump the version in the blead branch
1352 in git, e.g. 5.12.0 to 5.13.0.
1354 First, add a new feature bundle to F<regen/feature.pl>, initially by just
1355 copying the exiting entry, and bump the file's $VERSION (after the __END__
1358 "5.14" => [qw(switch say state unicode_strings)],
1359 + "5.15" => [qw(switch say state unicode_strings)],
1361 Run F<regen/feature.pl> to propagate the changes to F<lib/feature.pm>.
1363 Then follow the section L<"Bump the version number"> to bump the version
1364 in the remaining files and test and commit.
1366 If this was a BLEAD-POINT release, then just follow the section
1367 L<"Bump the version number">.
1369 After bumping the version, follow the section L<"update INSTALL"> to
1370 ensure all version number references are correct.
1372 (Note: The version is NOT bumped immediately after a MAINT release in order
1373 to avoid confusion and wasted time arising from bug reports relating to
1374 "intermediate versions" such as 5.20.1-and-a-bit: If the report is caused
1375 by a bug that gets fixed in 5.20.2 and this intermediate version already
1376 calls itself 5.20.2 then much time can be wasted in figuring out why there
1377 is a failure from something that "should have been fixed". If the bump is
1378 late then there is a much smaller window of time for such confusing bug
1379 reports to arise. (The opposite problem -- trying to figure out why there
1380 *is* a bug in something calling itself 5.20.1 when in fact the bug was
1381 introduced later -- shouldn't arise for MAINT releases since they should,
1382 in theory, only contain bug fixes but never regressions.))
1384 =head3 clean build and test
1386 Run a clean build and test to make sure nothing obvious is broken. This is
1387 very important, as commands run after this point must be run using the perl
1388 executable built with the bumped version number.
1391 $ ./Configure -des -Dusedevel
1395 In particular, F<Porting/perldelta_template.pod> is intentionally exempted
1396 from podchecker tests, to avoid false positives about placeholder text.
1397 However, once it's copied to F<pod/perldelta.pod> the contents can now
1398 cause test failures. Problems should be resolved by doing one of the
1405 Replace placeholder text with correct text.
1409 If the problem is from a broken placeholder link, you can add it to the
1410 array C<@perldelta_ignore_links> in F<t/porting/podcheck.t>. Lines
1411 containing such links should be marked with C<XXX> so that they get
1412 cleaned up before the next release.
1416 Following the instructions output by F<t/porting/podcheck.t> on how to
1417 update its exceptions database.

1429 =head3 create maint branch
1431 I<You MUST SKIP this step for RC, BLEAD-POINT, MAINT>
1433 If this was a BLEAD-FINAL release (i.e. the first release of a new maint
1434 series, 5.x.0 where x is even), then create a new maint branch based on
1435 the commit tagged as the current release.
1437 Assuming you're using git 1.7.x or newer:
1439 $ git checkout -b maint-5.12 v5.12.0
1440 $ git push origin -u maint-5.12
1443 =for checklist skip BLEAD-POINT MAINT RC
1445 =head3 make the maint branch available in the APC
1447 Clone the new branch into /srv/gitcommon/branches on camel so the APC will
1448 receive its changes.
1450 $ git clone --branch maint-5.14 /gitroot/perl.git \
1451 ? /srv/gitcommon/branches/perl-5.14.x
1452 $ chmod -R g=u /srv/gitcommon/branches/perl-5.14.x
1454 And nag the sysadmins to make this directory available via rsync.

1460 =head3 copy perldelta.pod to blead
1462 I<You MUST SKIP this step for RC, BLEAD-POINT>
1464 Copy the perldelta.pod for this release into blead; for example:
1467 $ cp -i ../5.10.x/pod/perldelta.pod pod/perl5101delta.pod #for example
1468 $ git add pod/perl5101delta.pod
1470 Don't forget to set the NAME correctly in the new file (e.g. perl5101delta
1471 rather than perldelta).
1473 Edit F<pod/perl.pod> to add an entry for the file, e.g.:
1475 perl5101delta Perl changes in version 5.10.1
1477 Then rebuild various files:
1479 $ perl Porting/pod_rules.pl
1481 Finally, commit and push:
1483 $ git commit -a -m 'add perlXXXdelta'
1484 $ git push origin ....

1502 =head2 Building a release - the day after
1504 =for checklist skip BLEAD-FINAL MAINT RC
1506 =head3 update Module::CoreList
1508 I<After a BLEAD-POINT release only>
1510 After Module::CoreList has shipped to CPAN by the maintainer, update
1511 Module::CoreList in the source so that it reflects the new blead
1518 Update F<Porting/Maintainers.pl> to list the new DISTRIBUTION on CPAN,
1519 which should be identical to what is currently in blead.
1523 Bump the $VERSION in F<dist/Module-CoreList/lib/Module/CoreList.pm>
1524 and F<dist/Module-CoreList/lib/Module/CoreList/Utils.pm>.
1528 If you have a local CPAN mirror, run:
1530 $ ./perl -Ilib Porting/corelist.pl ~/my-cpan-mirror
1534 $ ./perl -Ilib Porting/corelist.pl cpan
1536 This will update F<dist/Module-CoreList/lib/Module/CoreList.pm> and
1537 F<dist/Module-CoreList/lib/Module/CoreList/Utils.pm> as it did before,
1538 but this time adding new sections for the next BLEAD-POINT release.
1542 Add the new $Module::CoreList::VERSION to
1543 F<dist/Module-CoreList/Changes>.
1547 Remake perl to get your changed .pm files propagated into F<lib/> and
1548 then run at least the F<dist/Module-CoreList/t/*.t> tests and the
1549 test_porting makefile target to check that they're ok.
1555 $ ./perl -Ilib -MModule::CoreList \
1556 -le 'print Module::CoreList->find_version($]) ? "ok" : "not ok"'
1558 and check that it outputs "ok" to prove that Module::CoreList now knows
1559 about blead's current version.
1563 Commit and push your changes.
1567 =head3 check tarball availability
1569 Check various website entries to make sure the that tarball has appeared
1570 and is properly indexed:
1576 Check your author directory under L<https://www.cpan.org/authors/id/>
1577 to ensure that the tarballs are available on the website.
1581 Check F</src> on CPAN (on a fast mirror) to ensure that links to
1582 the new tarballs have appeared: There should be links in F</src/5.0>
1583 (which is accumulating all new versions), and (for BLEAD-FINAL and
1584 MAINT only) an appropriate mention in F</src/README.html> (which describes
1585 the latest versions in each stable branch, with links).
1587 The F</src/5.0> links should appear automatically, some hours after upload.
1588 If they don't, or the F</src> description is inadequate,
1589 ask Ask <ask@perl.org>.
1593 Check L<https://www.cpan.org/src/> to ensure that the F</src> updates
1594 have been correctly mirrored to the website.
1595 If they haven't, ask Ask <ask@perl.org>.
1599 Check L<https://metacpan.org> to see if it has indexed the distribution.
1600 It should be visible at a URL like C<https://metacpan.org/release/DAPM/perl-5.10.1>.
1604 =head3 update release manager's guide
1606 Go over your notes from the release (you did take some, right?) and update
1607 F<Porting/release_managers_guide.pod> with any fixes or information that
1608 will make life easier for the next release manager.
