+=head1 MAKING A CHECKLIST
+
+If you are preparing to do a release, you can run the
+F<Porting/make-rmg-checklist> script to generate a new version of this
+document that starts with a checklist for your release.
+
+This script is run as:
+
+ perl Porting/make-rmg-checklist \
+ --type [BLEAD-POINT or MAINT or ...] > /tmp/rmg.pod
+
+You can also pass the C<--html> flag to generate an HTML document instead of
+POD.

+ perl Porting/make-rmg-checklist --html \
+ --type [BLEAD-POINT or MAINT or ...] > /tmp/rmg.html
=head1 SYNOPSIS
This document describes the series of tasks required - some automatic, some
-manual - to produce a perl release of some description, be that a snaphot,
-release candidate, or final, numbered release of maint or blead.
+manual - to produce a perl release of some description, be that a release
+candidate, or final, numbered release of maint or blead.
The release process has traditionally been executed by the current
pumpking. Blead releases from 5.11.0 forward are made each month on the
and is a base for ideas on how the various tasks could be automated
or distributed.
-The outline of a typical release cycle is as follows:
+The checklist of a typical release cycle is as follows:
(5.10.1 is released, and post-release actions have been done)
... the cycle continues ...
+
=head1 DETAILS
Some of the tasks described below apply to all four types of
type of release, you will see a notation to that effect at
the beginning of the step.

+5.14.0. That is to say, it's the big new release once per year.
It's essentially the same procedure as for making a release candidate, but
with a whole bunch of extra post-release steps, even more than for MAINT.

=head2 Prerequisites
Before you can make an official release of perl, there are a few
hoops you need to jump through:
-=over 4
-
-=item PAUSE account
+=head3 PAUSE account with pumpkin status
Make sure you have a PAUSE account suitable for uploading a perl release.
If you don't have a PAUSE account, then request one:
https://pause.perl.org/pause/query?ACTION=pause_04imprint
-=item search.cpan.org
+=head3 search.cpan.org pumpkin status
Make sure that search.cpan.org knows that you're allowed to upload
perl distros. Contact Graham Barr to make sure that you're on the right
list.
-=item CPAN mirror
-
-Some release engineering steps require a full mirror of the CPAN.
-Work to fall back to using a remote mirror via HTTP is incomplete
-but ongoing. (No, a minicpan mirror is not sufficient)

-=item git checkout and commit bit
+=head3 git checkout and commit bit
You will need a working C<git> installation, checkout of the perl
git repository and perl commit bit. For information about working

resolve the issue.

Some of the following steps should be done regularly, but all I<must> be
done in the run up to a release.

+=head3 dual-life CPAN module synchronisation
Ensure that dual-life CPAN modules are synchronised with CPAN. Basically,
run the following:
and maint are synchronised with a particular CPAN module, but one might
have some extra changes.
-=item *
+
+=head3 dual-life CPAN module stability
Ensure dual-life CPAN modules are stable, which comes down to:
no - note it in perldelta as a significant bugfix
(also, try to inform the module's author)
-=item *
+
+=head3 monitor smoke tests for failures
Similarly, monitor the smoking of core tests, and try to fix. See
L<http://doc.procura.nl/smoke/index.html> for a summary. See also
L<http://www.nntp.perl.org/group/perl.daily-build.reports/> which has
the raw reports.
-=item *

Similarly, monitor the smoking of perl for compiler warnings, and try to
fix.
-=item *
+
+=head3 update perldelta
Get perldelta in a mostly finished state.
every section it lists is, if necessary, populated and complete. Copy
edit the whole document.
-=item *
-Bump the version number (e.g. from 5.12.0 to 5.12.1).
+=head3 Bump the version number
+
+Increase the version number (e.g. from 5.12.0 to 5.12.1).
For a BLEAD-POINT release, this can happen on the day of the release. For a
release candidate for a stable perl, this should happen a week or two
subsequent release candidates and the final release, it it not necessary to
bump the version further.
-There is a tool to semi-automate this process. It works in two stages.
-First, it generates a list of suggested changes, which you review and
-edit; then you feed this list back and it applies the edits. So, first
-scan the source directory looking for likely candidates. The command line
-arguments are the old and new version numbers, and -s means scan:
-
- $ ./perl -Ilib Porting/bump-perl-version -s 5.10.0 5.10.1 > /tmp/scan
-
-This produces a file containing a list of suggested edits, e.g.:
+There is a tool to semi-automate this process:
- NetWare/Makefile
+ $ ./perl -Ilib Porting/bump-perl-version -i 5.10.0 5.10.1
- 89: -MODULE_DESC = "Perl 5.10.0 for NetWare"
- +MODULE_DESC = "Perl 5.10.1 for NetWare"
+Remember that this tool is largely just grepping for '5.10.0' or whatever,
+so it will generate false positives. Be careful not change text like
+"this was fixed in 5.10.0"!
-i.e. in the file F<NetWare/Makefile>, line 89 would be changed as shown.
-Review the file carefully, and delete any -/+ line pairs that you don't
-want changing. You can also edit just the C<+> line to change the
-suggested replacement text. Remember that this tool is largely just
-grepping for '5.10.0' or whatever, so it will generate false positives. Be
-careful not change text like "this was fixed in 5.10.0"! Then run:
-
- $ ./perl -Ilib Porting/bump-perl-version -u < /tmp/scan
-
-which will update all the files shown.
+Use git status and git diff to select changes you want to keep.
Be particularly careful with F<INSTALL>, which contains a mixture of
C<5.10.0>-type strings, some of which need bumping on every release, and
The line in F<INSTALL> about "is binary incompatible with" requires a
correct choice of earlier version to declare incompatibility with.
-Also note that this tool
-currently only detects a single substitution per line: so in particular,
-this line in README.vms needs special handling:
-
- rename perl-5^.10^.1.dir perl-5_10_1.dir
-
When doing a BLEAD-POINT or BLEAD-FINAL release, also make sure the
C<PERL_API_*> constants in F<patchlevel.h> are in sync with the version
you're releasing, unless you're

+At this point you may want to compare the commit with a previous bump to
+see if they look similar. See commit 8891dd8d for an example of a
+previous version bump.
+
+When the version number is bumped, you should also update Module::CoreList
+(as described below in L<"update Module::CoreList">) to reflect the new
version number.
-=item *
+
+=head3 update INSTALL
Review and update INSTALL to account for the change in version number;
in particular, the "Coexistence with earlier versions of perl 5" section.
For BLEAD-POINT releases, it needs to refer to the previous BLEAD-POINT
release (so for 5.15.3 this would be 5.15.2).
+=head3 Check more build configurations
-=item *
-
-Update the F<Changes> file to contain the git log command which would show
-all the changes in this release. You will need assume the existence of a
-not-yet created tag for the forthcoming release; e.g.
-
- git log ... perl-5.10.0..perl-5.12.0
-
-Due to warts in the perforce-to-git migration, some branches require extra
-exclusions to avoid other branches being pulled in. Make sure you have the
-correct incantation: replace the not-yet-created tag with C<HEAD> and see
-if C<git log> produces roughly the right number of commits across roughly the
-right time period (you may find C<git log --pretty=oneline | wc> useful).
-
-=item *
-
-Check some more build configurations. The check that setuid builds and
-installs is for < 5.11.0 only.
+Check some more build configurations.
$ sh Configure -Dprefix=/tmp/perl-5.x.y -Uinstallusrbinperl \

+=head3 bump version number
For a BLEAD-POINT release, if you did not bump the perl version number as
part of I<advance actions>, do that now.
-=item *
-Finalize the perldelta. In particular, fill in the Acknowledgements
-section. You can generate a list of contributors with checkAUTHORS.pl.
-For example:
+=head3 finalize perldelta
- $ git log --pretty=fuller v5.13.${last}..HEAD | \
- perl Porting/checkAUTHORS.pl --who -
-
-Look at the previous L<perldelta> for how to write the opening
-paragraph of the Acknowledgements section. To get the amount of
-changed files and number of lines use this command:
-
- $ git diff --shortstat v5.13.${last}..HEAD | \
- ./perl -Ilib -nE 'my ($files, $insert, $delete) = /(\d+)/ga; say "$files files and ", $insert + $delete, " lines changed"'
+Finalize the perldelta. In particular, fill in the Acknowledgements
+section, which can be generated with something like:
-Making sure to round off the number of lines changed.
+ $ perl Porting/acknowledgements.pl v5.15.0..HEAD
Re-read the perldelta to try to find any embarrassing typos and thinkos;
remove any C<TODO> or C<XXX> flags; update the "Known Problems" section
Also, you may want to generate and view an HTML version of it to check
formatting, e.g.
- $ ./perl -Ilib ext/Pod-Html/pod2html pod/perldelta.pod > /tmp/perldelta.html
+ $ ./perl -Ilib ext/Pod-Html/bin/pod2html pod/perldelta.pod > /tmp/perldelta.html

If you make changes, be sure to commit them.

+=for checklist skip BLEAD-POINT MAINT RC
-Make sure you have a gitwise-clean perl directory (no modified files,
-unpushed commits etc):
+=head3 remove stale perldeltas
+
+For the first RC release that is ONLY for a BLEAD-FINAL, the perldeltas
+from the BLEAD-POINT releases since the previous BLEAD_FINAL should have
+now been consolidated into the current perldelta, and hence are now just
+useless clutter. They can be removed using:
+
+ $ git rm <file1> <file2> ...
+
+For example, for RC0 of 5.16.0:
+
+ $ cd pod
+ $ git rm perldelta515*.pod
+
+All mention to them should also be removed. Edit F<pod/perl.pod> to remove
+them from its table of contents, then run F<Porting/pod_rules.pl> to
+propagate your changes there into all the other files that mention them
+(including F<MANIFEST>). You'll need to C<git add> the files that it changes.

+or the C<advancecomp> port on macports - 7-Zip on Windows is the
+same code as AdvanceCOMP, so Windows users get the smallest files

+up.

the tarball and directory name:
XXX if we go for extra tags and branches stuff, then add the extra details
here
-Optionally, you might want to compress your tarball more. Unix F<gzip>

+=head4 Download the tarball to another machine
Download the tarball to some other machine. For a release candidate,
you really want to test your tarball on two or more different platforms

to find willing victims.

-directory, as at least one of the pod files it expects to find is
-autogenerated: perluniprops.pod. But you can't build perl if you've added
-the new perldelta file and not updated toc. So, make sure you have a built
-perl (with a pod/perluniprops.pod file) now, I<>before> continuing.
-
-First, update the F<pod/.gitignore> file to ignore the next
-release's generated F<pod/perlNNNdelta.pod> file rather than this release's
-one which we are about to set in stone (where NNN is the perl version number
-without the dots. i.e. 5135 for 5.13.5).
-
- $ (edit pod/.gitignore )
- $ git add pod/.gitignore
+=over 4
-Then, move the existing F<pod/perldelta.pod> to F<pod/perlNNNdelta.pod>,
-and edit the moved delta file to change the C<NAME> from C<perldelta> to
-C<perlNNNdelta>. For example, assuming you just released 5.10.1, and are
-about to create the 5.10.2 perldelta:

- $ rm pod/perl5101delta.pod # remove the auto-generated file, if any
- $ git mv pod/perldelta.pod pod/perl5101delta.pod
- $ (edit pod/perl5101delta.pod to retitle)
- $ git add pod/perl5101delta.pod
+Confirm that you have a clean checkout with no local changes.
-Then create a new empty perldelta.pod file for the new release; see
-F<Porting/how_to_write_a_perldelta.pod>. You should be able to do this by
-just copying in a skeleton template and then doing a quick fix up of the
-version numbers. Then commit the move and the new file.
