=head1 Release Instructions

To prepare a release:

=over 4

=item 0.

As soon as you become the release manager: review the goals for the release on
the Parrot roadmap (L<https://trac.parrot.org/parrot/wiki/ParrotRoadmap>) and
announce the tasks to the Parrot mailing list.  Make sure everyone knows what
they've committed to accomplish in time for the release.

A couple of weeks in advance: Ask people to run C<make fulltest> and
report (and hopefully fix!) any problems they find. Check in with
language project leads for release blockers, to allow time to fix them.
Also ask people to review the tickets targeted for the upcoming release
L<https://trac.parrot.org/parrot/roadmap>. Make sure your ssh keys have
been added to the FTP server, so you'll be able to ship the release (any
previous release manager can help).

A couple of days in advance: announce the new release to
parrot-dev@lists.parrot.org and to the IRC channel #parrot. Ask whether
there are any showstopping bugs. Check in again with the language
project leads. It's also good to ask for updates to F<NEWS>, F<CREDITS>,
F<PLATFORMS>, F<RESPONSIBLE_PARTIES>, F<DEPRECATED.pod> and
L<https://trac.parrot.org/parrot/wiki/Languages>.

You might also select a name (and optionally a quote) for your release.
For example, you could select a name from
L<http://en.wikipedia.org/wiki/List_of_parrots>.

Set up your account on L<http://www.parrot.org/> and ask an existing release
manager to provide you with admin privileges if you don't already have them.

=item 1.

Make sure you're up to date:

 $ svn update

You may want to ask the developer base to stop committing big changes;
it will avoid complications.

=item 2.

Update files with version-specific information:

=over 4

=item a

Increment the version number in the following files:
F<VERSION>, F<MANIFEST.generated>, F<META.yml>, F<README>.

Also update the version number, date, and your name in the
the file: F<docs/parrothist.pod>.

Update this file, that is F<release_manager_guide.pod>,
to remove the pending release you're in the middle of.

=item b

Update F<ChangeLog>, F<NEWS> with the new version number and any other
changes that have occurred since the last release: Hopefully these files
are being updated as committers work. If not, it's probably a good idea
to gather the updates weekly rather than waiting until the day of the
monthly release.

=item c

Update release-related information in F<tools/util/release.json>. This will be
used later when making release announcements.  There are a few essential
fields that must be updated at each release:

=over 4

=item C<release.*>

The date of the next release is in L<Appendix 1|"Appendix 1 - Upcoming releases">.

=item C<bugday.date>

Enter the date of the Saturday before the next release.

=item C<wiki.bugday>

Update the date part of the link to the wiki page for the next bugday.

=item C<ftp.path>

The URL of the FTP directory where the Parrot tarball can be found.

=back

=item d

Make sure F<RESPONSIBLE_PARTIES> is still accurate.

=item e

Give yourself credit for the release in F<CREDITS>.

=item f

Configure parrot and run C<make distro_tests>, and either fix
what those tests complain about, or fix them so they don't complain.

=item g

If this is a developer release, or there have been no new entries to the
F<PBC_COMPAT> file, skip this step.

If this is a supported release, and new entries to F<PBC_COMPAT> have been
added since the last supported release, make a new entry with a new major
version number for this release at the top of the list.

  3.0     2007.10.17      coke    released 0.4.17

Delete all minor version numbers since the last major bytecode version number,
as these are only used in development and not relevant to the bytecode support
policy. (Those changes are all included within the major version number
increase for the supported release.)

Once you've updated PBC_COMPAT, run C<tools/dev/mk_native_pbc> to update the
pbc files used in the native pbc tests.

=item h

Make sure everything works:

 $ make realclean
 $ perl Configure.pl --test ...
 $ make world docs html 2>&1 | tee make_world_docs_html.log
 $ make fulltest        2>&1 | tee make_fulltest.log

Note that running "make fulltest" takes a while and that separate
harnesses are being run.

=back

=item 3.

When all is well, then commit your changes:

 svn diff | more
 svn commit

Write down the revision number from this commit. You will need it later in
step 7.

=item 4.

Prepare the release tarball.

 $ make release VERSION=a.b.c

where a.b.c is the version number. This will create the tarball named
F<parrot-a.b.c.tar.gz>. This will automatically avoid including C<DEVELOPING>
in the release tarball.

=item 5.

Untar F<parrot-a.b.c.tar.gz> into another area.

=item 6.

Make sure everything works:

 $ perl Configure.pl
 $ make world docs html 2>&1 | tee make_world_docs_html.log
 $ make fulltest        2>&1 | tee make_fulltest.log

Verify that the version is correct and doesn't contain the suffix C<devel>:

 $ ./parrot -V

=item 7.

Tag the release as "RELEASE_a_b_c", where a.b.c is the version number.
Specify the revision number generated in step 3, above.

 $ export SVNPARROT=https://svn.parrot.org/parrot
 $ svn copy -r <REV> -m "tagged release a.b.c" \
   $SVNPARROT/trunk $SVNPARROT/tags/RELEASE_a_b_c

=item 8.

SSH to ftp-osl.osuosl.org. (If you don't have the necessary login information,
get it from one of the previous release managers.)

 $ ssh -l <USERNAME> ftp-osl.osuosl.org

If the release is a monthly development release, create a new directory under
F<~/ftp/releases/devel>.

 $ mkdir ~/ftp/releases/devel/a.b.c

If the release is in the stable series (L<Appendix 1 - Upcoming releases>)
create the new directory in F<~/ftp/releases/stable> instead.

 $ mkdir ~/ftp/releases/stable/a.b.c

Copy the tarball from your machine into the new directory.

 $ scp parrot-a.b.c.tar.gz <USERNAME>@ftp-osl.osuosl.org:~/ftp/releases/devel/a.b.c/.

(Or using C<wget> or whatever tool you prefer.)

When you're finished making changes, run the trigger script to push the changes
out to the FTP mirrors.

  ~/trigger-parrot

Check your changes at F<ftp://ftp.parrot.org/pub/parrot/releases>. It should
only take a few minutes for the mirrors to sync.

=item 9.

Compose the release announcement.  Use F<tools/util/crow.pir> to make
this part easier.  You can specify the format of your announcements like so:

  $ ./parrot tools/util/crow.pir --type=text
  $ ./parrot tools/util/crow.pir --type=html

Take the screen output and paste it into the application you need.  HTML
works well for use Perl and PerlMonks, and text for the rest.  It is not a
bad idea to add a "highlights" section to draw attention to major new
features, just be sure to say the same thing in both text and HTML versions.

=item 10.

Update the website. You will need an account with administrative rights
on L<http://www.parrot.org>.

=over 4

=item a

Add a new page for the release announcement with "Create content" -> "Story".
There's some additional stuff needed at the top of the page; use one of the
old announcements as a guide.

The "<!--break-->" line marks the end of the text that will appear on the
front page.

=item b

For the "News" category, select both "Releases" and "News".

Add tags to the page for significant changes in this release (e.g. "rakudo" for
significant Rakudo language updates, or "gc" for significant garbage collection
subsystem updates).

=item c

Under "URL path settings" uncheck "Automatic alias" and set the path to
news/[year]/Parrot-[release number].

=item d

Under "Publishing options" make sure "Published" and "Promoted to front page"
are checked.

=item e

Under "Administer" -> "Site building" -> "URL Redirects", change the URL for
"release/current" to the FTP directory for the new release (for example,
F<ftp://ftp.parrot.org/pub/parrot/releases/devel/0.8.1>). Also update
the URL for "release/developer" or "release/supported" depending on
which type of release this is.

=back

Preview the new page, and submit it.

(The old release announcement may be edited to uncheck "Promoted to front page"
to keep the main page fresh.)

=item 11.

Publicize the release by publishing the announcement through the
following channels (and any others you can think of):

=over 4

=item a

Send a text email to parrot-dev, perl6-language, perl6-announce,
perl5-porters, etc.  You should also include LWN.net in this mailing; email to
C<lwn> at that domain.

=item b

Submit the use Perl announcement story to use Perl, Perl Monks, Slashdot,
Newsforge, etc.  Don't forget to set a Reply-To: or Followup-To: header, if
your mail client lets you.

=item c

Modify the topic on #parrot, e.g.:

 /topic #parrot Parrot 0.4.8 Released | http://parrot.org/

=item d

Update the wiki frontpage at L<http://trac.parrot.org/parrot/>.

=item e

Update the Wikipedia entry at L<http://en.wikipedia.org/wiki/Parrot_virtual_machine>.

=item f

Update the C2 wiki entry at L<http://c2.com/cgi/wiki?ParrotCode>.

=back

=item 12.

Review the milestone for the current release in Trac at
L<https://trac.parrot.org/parrot/roadmap>. Close any completed
release-related tickets. Edit the milestone to mark it as "Completed".
Marking a milestone as completed will migrate all open tickets to a
selected milestone (generally the next milestone). Non-critical tickets
can have their milestone unset.

=item 13.

Add the version to Trac so new bug reports can be filed against your
buggy code. L<https://trac.parrot.org/parrot/admin/ticket/versions>.

Make the latest released version the default version for new reports.

Remove any sufficiently old versions listed there.

=item 14.

You're done! Help yourself to a beer, cola, or other celebratory drink.

=back

=head2 ABOUT THIS DOCUMENT

This document was written after a couple of subtly incorrectly assembled
releases--usually when someone forgot to delete F<DEVELOPING> (which is now
automated!), but at least once where the F<MANIFEST> check failed. The intent
of this file is to document what must be done to release so that such mistakes
won't happen again.

=head1 SEE ALSO

F<README>, F<RESPONSIBLE_PARTIES>.

=head1 Appendix 1 - Upcoming releases

To make a monthly release schedule possible, we spread the burden of
releases across multiple release managers. Releases are scheduled for
the 3rd Tuesday of each month.

The starred releases are Parrot's twice-yearly supported releases, see
F<docs/project/support_policy.pod>.
