openstack-releasing - A set of scripts to handle OpenStack release process

How to Release

Deliverables should all be using post-versioning, getting their version information from git tags and not having any version specifier in the setup.cfg.

Release requests are filed as patches to deliverables files in the openstack/releases repository, see the README there for more details.

Before beginning this process, you need to set up gpg with a valid key, and authorize launchpad to run the release tools commands. Authorizing launchpad can be tricky on a system that only provides a terminal-based browser, since the launchpad site does not work well with the default configuration of lynx (cookies and referrer headers need to be enabled for the launchpad site). Newer versions of launchpadlib also rely on keyring, which may require a password for every command being run if you are not in a graphical environment with a better interactive key manager. Talk with dhellmann if you start a release and run into trouble with launchpad auth.

When a release request is ready to be approved, follow these steps:

The release team member taking responsibility for the release should approve the change in openstack/releases. Release requests should not be approved until we are actually ready to cut the release.
After the release request merges, check out or update a local copy of openstack/releases to get the new version of the file under the deliverables directory. Make sure you check out the releases repository to the commit with the new release request you want to process, in case multiple requests merge around the same time. The release tools only look at the most recent commit to detect which deliverable files have changed.
Check out or update a local copy of openstack-infra/project-config repository, which contains the tools for tagging a release.
Change directories to project-config/jenkins/scripts/release-tools.
Create or update a virtualenv and install all of the dependencies for the release tools using openstack-infra/project-config/jenkins/scripts/release-tools/requirements.txt as the basis.

For example:
```
$ virtualenv .venv
$ source .venv/bin/activate
$ pip install -U -r requirements.txt
```
Run release_from_yaml.sh, giving the path to the openstack/releases repository.

For example:
```
$ ./release_from_yaml.sh ~/repos/openstack/releases
```
As the release script runs, it will prompt you for your GPG key passphrase before adding the tag. This gives you a last chance to review the proposed tag before proceeding. After the tag is created locally and pushed up to the remote server, the script will push comments to closed Launchpad bugs since the previous tag.
Announce the release.
1. Milestones are manually announced once all projects are done (usually at the closing of the milestone window), using an email recapitulating all projects that did a milestone tag and pointing to milestone tarballs. The process to follow for announcements of releases will be added here soon.
2. Library and tool releases are announced via one of the OpenStack mailing lists. See the instructions for running announce.sh below.

Prerequisites

The prerequisites for all of the scripts are defined in requirements.txt.

Each shell script should try to create a Python virtualenv to install the packages before running any of the commands written in Python. If you start seeing import errors after updating your sandbox, it is likely that a new dependency was added. Try removing .tox/venv and running the command again.

Top-level scripts

The top-level scripts call the various base tools to get their work done.

Note

The scripts involved in tagging releases have moved from this repository to openstack-infra/project-config/jenkins/scripts/release-tools.

announce.sh

This script generates an email message ready to be sent to announce the release of a library or other tool. Note that the EMAIL environment variable needs to be set prior to running the tool.

Example:

./announce.sh ~/repos/openstack/oslo.rootwrap
./announce.sh ~/repos/openstack/oslo.rootwrap 3.0.3

The output goes to relnotes/ in a file named for the project and version. For example, the announcement for the rootwrap release above would be written to relnotes/oslo.rootwrap-3.0.3.

rccut.sh

Final release for pre-versioned components follows a slightly different process. Just before RC1 we need to create a stable/* release branch. rccut.sh creates a stable/$SERIES branch from the specified SHA, and turns all Launchpad bugs for the RC1 milestone to FixReleased (which means "present in the release branch").

It supports deliverables with multiple repositories, using an additional parameter to point to the main deliverable (in which case it skips Launchpad update). It special-cases oslo-incubator, where it doesn't wait for a tarball to be built.

Examples:

./rccut.sh 7432f32d838ab346c liberty nova

Create a series/liberty branch for Nova at commit 7432f32d838ab346c, and mark FixCommitted bugs FixReleased, while targeting them to the juno-rc1 milestone.

./rccut.sh 3472368b3a546d liberty neutron-fwaas neutron

Create a series/liberty branch for neutron-fwaas at commit 3472368b3a546d.

rcdelivery.sh

This script is used for pre-versioned projects to publish RCs and final release from the stable/$SERIES branch. It applies the RC or final tag, pushes it, waits for the tarball build, and uploads the resulting tarball to Launchpad (while marking it released).

It supports deliverables with multiple repositories, using an additional parameter to point to the main deliverable (in which case it uploads to the main Launchpad page). It special-cases oslo-incubator, where no tarball is generated or needs to be uploaded.

Examples:

./rcdelivery.sh kilo rc1 cinder

Push 2015.1.0rc1 tag to current cinder stable/kilo branch HEAD, wait for the tarball build, and upload the resulting tarball to Launchpad (while marking it released).

./rcdelivery kilo final neutron-fwaas neutron

Push 2015.1.0 final tag to current neutron-fwaas stable/kilo branch HEAD (which should be the last RC), wait for the tarball build, and upload the resulting tarball to the "neutron" Launchpad page.

release-notes

This produces a set of release notes intended to be sent as an announcement email when a new library or package is produced. It is more suitable for libraries than for the major projects, because it includes a list of all of the changes and diff-stats output to show which files changed.

The script parses the README.rst to find a line matching "Bugs:", extracts the URL following the colon, and includes that information in the output.

The bugs URL is converted to a launchpad project URL and combined with the final version number to produce a milestone URL.

The script uses python setup.py to determine the project name and the one-line description to include in the output text.

Examples:

release-notes ~/repos/openstack/oslo.config 1.7.0 1.8.0

Print the release notes between versions 1.7.0 and 1.8.0 for the project in the ~/repos/openstack/oslo.config directory.

release-notes --show-dates --changes-only ~/repos/openstack/oslo.config 1.8.0 HEAD

Print the list of changes after 1.8.0 for the project in the ~/repos/openstack/oslo.config directory, including the date of the change but leaving out the email message boilerplate. This mode is useful for examining the list of unreleased changes in a project to decide if a release is warranted and to pick a version number.

latest-deliverable-versions

Show each repository and the latest tag recorded in the deliverable file associated with that repo.

latest-deliverable-versions -r ~/repos/openstack/releases mitaka

Test or configure the launchpad credentials. This will set up a keyring entry for the launchpad site, prompt for credentials, and handle the OAuth handshake. All of the other launchpad-connected commands will do these steps, too, but this command takes no other action after logging in so it is safe to run it repeatedly.

check_library_constraints.sh

Script to check the current list of constraints against the most recent release for all of the library projects. This script can be used at any point, but is especially intended to ensure that the constraints for things we release are all updated at the end of a release cycle. To run the script, check out both the release-tools and requirements repositories and then run the script as:

$ check_library_constraints.sh /path/to/requirements-repository stable/mitaka

milestone-checkup

Tool to report on the status of milestone tags for projects using the cycle-with-milestone release model.

$ milestone-checkup ~/repos/openstack/releases newton 2
training-labs (Documentation)
  did not find /home/dhellmann/repos/openstack/releases/deliverables/newton/training-labs.yaml

aodh (Telemetry)
  did not find /home/dhellmann/repos/openstack/releases/deliverables/newton/aodh.yaml

ceilometer (Telemetry)
  did not find /home/dhellmann/repos/openstack/releases/deliverables/newton/ceilometer.yaml

astara (astara)
...

Base tools

milestone-close

Marks a Launchpad milestone as released and sets it inactive so no more bugs or blueprints can be targeted to it.

Example:

milestone-close oslotest 1.8.0

milestone-rename

Renames a Launchpad milestone.

Example:

milestone-rename oslo.rootwrap next-juno 1.3.0

Rename oslo.rootwrap next-juno milestone to 1.3.0.

ms2version.py

Converts milestone code names (juno-1) to version numbers suitable for tags (2014.2.b1). If used with --onlycheck, only checks that the milestone exists in Launchpad (useful for Swift where the rules are different).

Examples:

./ms2version.py nova kilo-3

Returns 2015.1.0b3 (after checking that the kilo-3 milestone exists in Nova)

./ms2version.py swift 2.1.0 --onlycheck

Exists successfully if there is a 2.1.0 milestone in Swift.

repo_tarball_diff.sh

This script fetches a specific branch from a git repository into a temp directory and compares its content with the content of a tarball produced from it (using "python setup.py sdist"). The difference should only contain additional generated files (Changelog, AUTHORS...) and missing ignored files (.gitignore...).

Example:

./repo_tarball_diff.sh nova master

Check the difference between Nova master branch contant and a tarball that would be generated from it.

compare_tarball_diff.sh

Download published tarballs and compare them against what is produced by running the sdist command locally. This can be used to verify that a tarball published for download was built correctly and has not been modified.

Example:

./compare_tarball_diff.sh openstack/nova 13.0.0

validate_tarballs.sh

Given a release series, download and validate all of the tarballs to ensure that they match what was tagged.

Example:

./validate_tarballs.sh ~/repos/openstack/releases mitaka

pre_expire.py

This script fetches opened bugs for a project in order to prepare bugs with no activity in the last D days for expiration by: - unsetting bug assignee - unsetting bug milestone - setting bug status to Incomplete - adding a comment explaining why we updated the bug

Examples:

./pre_expire_bugs.py neutron --days 180

Prepare for expiration neutron bugs with no activity not updated in the last 180 days.

./pre_expire_bugs.py glance --days 365 --test

Test prepare for expiration on Launchpad Staging servers.

./pre_expire_bugs.py glance --days 365 --dry-run

Prepare for expiration dry-run: print actions without executing them.

expire_old_bug_reports.py

Closes Launchpad bug reports which are older than the oldest stable release (usually 18 months, see DAYS_SINCE_CREATED). It ignores bug reports which: * have a special comment (see constant STILL_VALID_FLAG). * have the status In Progress * have the importance Wishlist By default it uses a dry-run to not accidentally close bug reports. You have to use a flag to make it a real execution.

Closed bug reports will have: * status = Won't Fix * assignee = None * importance = Undecided * a comment which explains why this was done.

Examples:

./expire_old_bug_reports.py nova --verbose

Show which bug reports of Nova would be expired (a dry-run is the default).

./expire_old_bug_reports.py nova --no_dry_run

Actually expire old bug reports of Nova.

./expire_old_bug_reports.py nova --no_dry_run --credentials-file cred.txt

Use a credentials file to expire bug reports (see launchpad-login).

export LP_CREDS_FILE=path/to/my/lp/credentials/files/cred.txt
./expire_old_bug_reports.py nova --no_dry_run

Use an environment variable to access the credentials file instead of the --credentials-file flag.

process_bugs.py

This script fetches bugs for a project (by default all "FixCommitted" bugs, or all open bugs targeted to a given milestone if you pass the --milestone argument) and sets a milestone target for them (--settarget) and/or sets their status to "Fix Released" (--fixrelease).

It ignores bugs that have already a milestone set, if that milestone does not match the one in --settarget.

Examples:

./process_bugs.py nova --settarget=grizzly-3 --fixrelease

Sets the target for all Nova FixCommitted bugs to grizzly-3 and mark them 'Fix Released'.

./process_bugs.py glance --settarget=grizzly-2 --status='Fix Released' --test

Test setting the target for all untargeted Glance FixReleased bugs to grizzly-2 on Launchpad Staging servers.

./process_bugs.py neutron --milestone juno-3 --settarget juno-rc1

Move all juno-3 open bugs from juno-3 to juno-rc1 milestone.

wait_for_tarball.py

This script queries Jenkins tarball-building jobs to find either a job matching the provided --mpsha SHA building milestone-proposed.tar.gz, or a job matching the provided --tag. It then waits for that job completion and reports the built tarball name.

Examples:

./wait_for_tarball.py cinder --mpsha=59089e56f674f5f94f67c5986e9a616bb669d846

Looks for a cinder-branch-tarball job matching SHA 59089e... which would produce a milestone-proposed.tar.gz tarball, and waits for completion

./wait_for_tarball.py cinder --tag=2013.1.1

Looks for a cinder-tarball job for tag "2013.1.1" and waits for completion.

upload_release.py

This script grabs a tarball from tarballs.openstack.org and uploads it to Launchpad, marking the milestone released and inactive in the process. If used with the --nop argument, it will only mark the milestone released and inactive (this is used for projects like oslo-incubator which do not release source code).

The script prompts you to confirm that the tarball looks like the one you intend to release, and to sign the tarball upload.

Examples:

./upload_release.py nova 2015.1.0 --milestone=kilo-3

Uploads Nova's nova-2015.1.0b3.tar.gz to the kilo-3 milestone page.

./upload_release.py glance 2015.1.0 --test

Uploads Glance's glance-2015.1.0.tar.gz to the final "2015.1.0" milestone as glance-2015.1.0.tar.gz, on Launchpad staging server

./upload_release.py cinder 2012.2.3 --tarball=stable-folsom

Uploads Cinder's current cinder-stable-folsom.tar.gz to the 2012.2.3 milestone as cinder-2012.2.3.tar.gz

consolidate_release_page.py

This script moves blueprints and bugs from interim milestones to the final release milestone page, in order to show all bugs and features fixed during the cycle. For Swift, this will only move X-rc* bugs and blueprints to final X release.

The --copytask mode is an experimental variant where a series bugtask is created and the release milestone is set on that bugtask, preserving the information from the "development" bugtask (and the milestone the bug was fixed in).

Examples:

./consolidate_release_page.py cinder kilo 2015.1.0

Moves Cinder blueprints and bugs from intermediary kilo milestones to the final 2015.1 milestone page.

./consolidate_release_page.py --test swift grizzly 1.8.0

Moves Swift 1.8.0-rc* blueprints and bugs to the final 1.8.0 page, on Launchpad staging server

./consolidate_release_page.py --copytask glance kilo 2015.1.0

Moves Glance blueprints from intermediary kilo milestones to the final 2015.1.0 milestone page. Creates kilo series task for all grizzly bugs and sets the milestone for those to 2015.1.0.

milestones-create

This script lets you create milestones in Launchpad in bulk. It is given a YAML description of the milestone dates and the projects to add milestones to. The script is idempotent and can safely be run multiple times. See create_milestones.sample.yaml for an example configuration file.

Example:

milestones-create havana.yaml

milestone-ensure

This script lets you create one series and milestone in Launchpad. The script is idempotent and can safely be run multiple times.

Example:

milestone-ensure oslo.config liberty next-liberty

spec2bp.py

This experimental script facilitates setting blueprint fields for approved specs. It takes the project and blueprint name as arguments. For specs that are still under review (--in-review) it will set them to "Blocked" (and definition status to Review). For approved specs it will set definition status to Approved, and set Spec URL. In both cases it will set the target milestone, approver name and specified priority (by default, 'Low').

Examples:

./spec2bp.py glance super-spec --milestone=juno-2 --priority=Medium

Glance's super-spec.rst was approved and you want to add it to juno-2, with Medium priority. This will do it all for you.

./spec2bp.py nova --specpath=specs/kilo/approved/my-awesome-spec.rst
  --in-review --milestone=juno-2

Nova's my-awesome-spec.rst is still under review, but you would like to add the my-awesome-spec blueprint to juno-2 (marked Blocked). Since it's located in a non-standard path, we specify it using --specpath parameter.

./spec2bp.py nova my-awesome-spec --priority=High

my-awesome-spec is now approved. You want to flip all the approval bits, but also change its priority to High. There is no need to pass --specpath again, spec2bp will infer it from the blueprint URL field.

stable_freeze.py

A script that can be used to quickly "freeze" all open reviews to a stable branch. It may also be used to "thaw" frozen reviews upon re-opening of the branch for merges. Reviews are frozen by adding a -2 and thawed by reverting that and adding a 0.

Examples:

To view open reviews for stable/icehouse 2014.1.4:

./stable_freeze.py -r 2014.1.4 query

View open reviews for stable/icehouse 2014.1.4.

./stable_freeze.py -r 2014.1.4 -o ~/openstack/2014.1.4-freeze.txt

Freeze all open reviews proposed to stable/icehouse. 2014.1.4-freeze.txt will contain all frozen reviews and this can be used to thaw later on.

./stable_freeze -r 2014.1.4 -i ~/openstack/2014.1.4-freeze.txt thaw

Thaw all reviews previously frozen and stored in 2014.1.4-freeze.txt.

./stable_freeze -r 2014.1.4 -i ~/openstack/2014.1.4-freeze.txt \
  -c 123777 -c 123778 freeze

Freeze individual changes that have been proposed after the stable freeze period started. References to these reviews will be appended to 2014.1.4-freeze.txt to be unfrozen later on.

autokick.py

A script to periodically clean up blueprints (adjusting series goal based on target milestone, and optionally kicking unpriotized blueprints from the milestone. ttx is running it in a cron so you don't have to.

Examples:

To clean up Nova kilo blueprints:

./autokick.py nova kilo

highest_semver.py

Reads a list of version tags from standard input and prints the "highest" value as output, ignoring tags that don't look like valid versions.

translation-cleanup.sh

A script to cleanup translations for a release. It updates all translation source files, downloads translation files and removes translation files that are not sufficiently translated. It results in a change that then needs to get reviewed and send to gerrits.

Examples:

To generate a cleanup patch for nova:

./translation-cleanup.sh kilo nova

adjust_blueprints.py

Run around milestone release time, this script retrieves and parses the list of blueprints for a given project and:

sets the milestone target and series goal on recently-implemented blueprints
removes the milestone target on incomplete milestone-targeted blueprints

Examples:

./adjust_blueprints.py nova liberty-1

Displays proposed adjustments around Nova liberty-1 blueprints.

./adjust_blueprints.py nova liberty-1 --target --clean

Targets missing implemented blueprints and cleans incomplete ones for Nova in liberty-1.

add-comment

Add a comment to a set of Launchpad bugs. This command requires basic Launchpad credentials (see launchpad-login).

Example:

add-comment --subject='Winner' --content='You won!' 1000000 2000000

Add a 'You won!' comment (with subject line 'Winner') to Launchpad bugs #1000000 and #2000000

update_reviews

Lift your -2 reviews from a project. Use this after the stable branch has been created and the project is ready for accept new features.

This tool uses the Gerrit REST API. So you need to provide your username and password somehow. You probably already have a .gertty.yaml, if not make one.

Example:

update_reviews oslo.config

The tool looks for all of the changes in the project that you have a -2 vote on and changes your vote to 0, with the message "This project is now open for new features."

bugs-fixed-since.py

List bugs mentioned in master commit messages starting from a specified commit.

Example:

./bugs-fixed-since.py -r ../neutron --start=8.0.0

Use -B option to ignore patches that were already backported into all stable branches.

Example:

./bugs-fixed-since.py -B -r ../neutron --start=8.0.0

Use -e option to ignore patches that don't apply cleanly to one of stable branches.

Example:

./bugs-fixed-since.py -e -r ../neutron --start=8.0.0

lp-filter-bugs-by-importance.py

Reads the list of Launchpad bug numbers on stdin and filters out those of importance specified. Filtering out Wishlist bugs if importance not specified.

Example:

./bugs-fixed-since.py [...] --start=8.0.0 | \
./lp-filter-bugs-by-importance.py neutron

List bugs that are fixed in master since 8.0.0 that are not of Wishlist importance.

Example:

./bugs-fixed-since.py --start=8.0.0 | \
./lp-filter-bugs-by-importance.py neutron | \
./lp-filter-bugs-by-importance.py neutron --importance Low

List bugs that are fixed in master since 8.0.0 that are not of Wishlist or Low importance.

lp-filter-bugs-by-tag.py

Reads the list of Launchpad bug numbers on stdin and filters out those with a tag specified.

Example:

./bugs-fixed-since.py [...] --start=8.0.0 | \
./lp-filter-bugs-by-tag.py neutron --tag in-stable-mitaka

List bugs that are fixed in master since 8.0.0 that don't have relevant fixes merged in stable/mitaka.

annotate-lp-bugs.py

Reads the list of Launchpad bug numbers on stdin and writes out a nice and detailed description for each of them.

Example:

./bugs-fixed-since.py [...] --start=8.0.0 | ./annotate-lp-bugs.py neutron

Pull in detailed description for bugs that are fixed in master since 8.0.0.

lp-reset-backport-potential.py

Clean up <>-backport-potential tags for bugs with in-stable-<> tag set.

Example:

./lp-reset-backport-potential.py neutron python-neutronclient

lp-tag.py

Append a tag to bugs specified on stdin.

Example:

./bugs-fixed-since.py [...] --start=8.0.0 | ./lp-tag.py foo-tag

This command will add the 'foo-tag' tag to all bugs fixed since 8.0.0.
