docs/project/release_manager_guid.pod - The Release Manager Guide.
This guide lays out in detail the steps necessary to prepare, assemble and publish a Parrot release.
Please ensure you carefully follow each step in the process. As always, please ask for help if you need it.
NOTE: You can use the newish/experimental script auto_release.pl to automate much of his guide (up to section IX):
perl tool/release/auto_release.pl X.Y.Z
Run perldoc on the tool to get more documentation. This tool is new and experimental. Your mileage may vary. Be prepared to do things manually if you have problems with this script.
#parrotor, alternatively, email a query to the
parrot-devmailing list. If there are goals for the release, please annouce them on
parrot-dev. As well, please ensure everyone understands what they've committed to accomplish in time for the release.
#parrotsketch. You may obtain a complete log of these meetings at http://irclog.perlgeek.de/parrotsketch/.
make fulltestand report (and hopefully fix!) any problems they discover. Check-in with language project leaders (e.g., Rakudo) for any potential release blockers. This will, hopefully, afford them sufficient time apply any fixes. Also, please ask people to review any issues targeted for the upcoming release at https://github.com/parrot/parrot/issues.
In order to do this, please ensure your public SSH key(s) have been added to the FTP server ftp-osl.osuosl.org. You can open a support ticket for this by sending an email to
email@example.com with your public SSH keys as attachments. Without them, you will not be able to ship the release.
Also, set up your account on http://parrot.org/. Any previous release manager should be able to help you, but you may also need to open a support ticket at
firstname.lastname@example.org in order to be added to the
parrot group. The
parrot group has permissions to create the new directories necessary to contain documentation for new releases.
email@example.com 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 http://github.com/parrot/parrot/blob/master/ChangeLog, http://github.com/parrot/parrot/blob/master/CREDITS, http://github.com/parrot/parrot/blob/master/PLATFORMS. http://github.com/parrot/parrot/blob/master/RESPONSIBLE_PARTIES, http://github.com/parrot/parrot/blob/master/api.yaml, and https://github.com/parrot/parrot/wiki/Languages.
#parrot, announcing the time you plan to start the release procedure. This will aid the committers.
The day of the release has arrived. Please ensure you have checked out the most recent version of the master branch:
git checkout master git pull --rebase
Also, ensure you do not have any local commits which have not yet been pushed and thoroughly tested. You can do so with the following command:
git log origin/master..
If this produces no output, then your local master and the remote master are in sync.
First, ensure you have configured Parrot (
perl Configure.pl) and ran
make html with the old version of Parrot. Second, save a copy of the entire 'docs/' directory to some temporary location; you will need them later in Section X below. Next, update files with the following version-specific information.
tools/release/update_version.pl to update the version string in several files. For example,
perl tools/release/update_version.pl 3.8.0
IMPORTANT: The version change you just made by running tools/release/update_version.pl invalidates any existing generated bytecode. Assuming you ran it in a directory with an existing build, you must now run
make reconfig to clear out any invalid bytecode.
Update the version number, the date, and your name in http://github.com/parrot/parrot/blob/master/docs/parrothist.pod.
Update this file (http://github.com/parrot/parrot/blob/master/docs/project/release_manager_guide.pod) to remove the pending release you're currently building.
to update ChangeLog with the new version number and a skeleton announcement.
Add any other changes which have occurred since the last release. Hopefully, the committers are updating these files as they work. But, if not, then it's probably a good idea to gather the updates weekly rather than wait until the day of the release.
make distro_tests. Then either fix what those tests complain about or fix the tests so they don't complain.
If this is a supported release and new entries to PBC_COMPAT have been added since the last supported release, add a new entry with a new major version number for this release at the top of the list. For example,
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 used only in development and are 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 - running
sh tools/dev/mk_packfile_pbc if necessary - then run
sh tools/dev/mk_native_pbc to update the PBC files used in the native PBC tests. Note: Parrot must already have built Parrot for this to work, and this script will reconfigure and rebuild Parrot with various primitive size options.
make realclean perl Configure.pl --test ... make world html 2>&1 | tee make_world_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.
When all is well, commit your changes:
git diff git add file1 file2 ... git commit -m "awesome and informative commit message"
Instead of adding files individually, you can also tell
git commit that you want all modified and deleted files to be in your next commit via the
git commit -a -m "awesome and informative commit message"
Be careful with
git commit -a as it could add files you do not mean to include. Verify the contents of your most recent commit look sane with:
If you want, you can note the SHA-1 digest from this commit by running,
git rev-parse master > SHA1_TO_REMEMBER
Update the repository on GitHub with,
git push origin master
There are two possible approaches to preparing and testing the release tarball: using
make release or using
Begin by running:
make release VERSION=a.b.c
where a.b.c is the version number (e.g.,
3.8.0). This will create the tarball named parrot-a.b.c.tar.gz. The DEVELOPING file is automatically excluded from the release tarball.
Extract parrot-a.b.c.tar.gz into another directory:
cp parrot-a.b.c.tar.gz ~/another/directory cd ~/another/directory tar -xvzf parrot-a.b.c.tar.gz
Verify that the build process runs smoothly:
perl Configure.pl make world html 2>&1 | tee make_world_html.log make fulltest 2>&1 | tee make_fulltest.log
As an alternative, you can package the release by running:
perl Configure.pl make release_check
This target (or, for short,
make relcheck), will prepare the tarball, copy it into a temporary directory, and then reconfigure, rebuild, re-test (with
make test) and re-release.
Whichever of these two approaches you use, verify the version is correct and does not contain the suffix
Tag the release as "RELEASE_a_b_c", where a.b.c is the version number:
git tag RELEASE_a_b_c git push --tags
Log in to ftp-osl.osuosl.org:
As mentioned previously, your public SSH key must be added to the list of authorized keys before you can log in.
If this is a development release, create a new directory under ~/ftp/releases/devel:
If this is a supported release, (see Appendix 1), create the new directory in ~/ftp/releases/supported instead:
Copy all the tarballs and their respective digest files from your machine into the new directory:
scp parrot-a.b.c.tar.gz \ parrot-a.b.c.tar.bz2 \ parrot-a.b.c.tar.gz.sha256 \ parrot-a.b.c.tar.bz2.sha256 \ firstname.lastname@example.org:~/ftp/releases/devel/a.b.c
You don't necessarily have to use
scp for this step. You can use whichever tool you prefer.
When you're finished making changes, run the trigger script to push the changes out to the FTP mirrors:
Verify your changes at ftp://ftp.parrot.org/pub/parrot/releases. It should only take a few minutes for the mirrors to sync.
Compose the release announcement. Use tools/release/crow.pir to make this part easier. You can specify the format of your announcements like so,
./parrot tools/release/crow.pir --type=text ./parrot tools/release/crow.pir --type=html
Copy the output and paste it into the application you need. HTML works well for Perl and PerlMonks and text works well for the rest. It's a good idea (although not necessary) to add a "highlights" section to draw attention to major new features. If you do, be sure to say the same thing in both the text and the HTML versions.
Please ensure you include the SHA256 sums of the tarballs in the release announcement which are automatically generated by
Update the website. You will need an account with editor rights on http://www.parrot.org.
The "<!--break-->" line marks the end of the text that will appear on the front page.
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).
release/currentto the FTP file for the new release (e.g. ftp://ftp.parrot.org/pub/parrot/releases/devel/3.8.0/parrot-3.8.0.tar.gz). Also update the URL for
release/supporteddepending on which type of release this is.
make htmlin a release copy of Parrot, and save the resources/ and html/ directories created in docs/. Use SSH to login to <username>@parrot.org and expand these into a release directory (e.g. 3.8.0) in the webroot (i.e., /var/www/docs.parrot.org/htdocs/parrot) for http://docs.parrot.org. In
<webroot>/parrot, there are symbolic links for
devel. Update the
latestsymlink to point to your new directory. If this is a supported release, also update the
supportedsymlink. Do not delete any old copies of the docs and don't update the other symlinks.
The old release announcement may be edited to uncheck Promoted to front page to keep the main page fresh.
To update both the
parrot.github.com and the relevant
parrot-docsx repositories, execute the following command:
Please note: To review the available options, use the
-h | --help option. In addition, you may also want to review the pod with,
For more information about the update process, see http://github.com/parrot/parrot/blob/master/docs/project/release_parrot_github_guide.pod.
Publicize the release by publishing the announcement through the following channels (and any others you can think of):
perl5-porters, etc. You should also include lwn.net in this mailing; email to
lwnat that domain.
