This document describes how to release Sentry. It is a work in progress and should be refined by the Release Manager (RM) as they come across aspects of the release process not yet documented here.

NOTE: For the purpose of illustration, this document assumes that the version being released is 1.28.0-incubating, and the following development version will become 12.30.0-incubating

Prerequisites

...

Frequently asked questions for making Apache releases are available on Releases FAQ page. Guide to Release Management During Incubation Release Process guide also has good information on best practices for releasing artifacts from an incubating Apache project.

The Release Manager (RM) must go through the policy document to understand all the tasks and responsibilities of running a release.

Give a heads up

The RM should first create an umbrella issue and then setup a timeline for release branch point. The time for the day the umbrella issue is created to the release branch point must be at least two weeks in order to give the community a chance to prioritize and commit any last minute features and issues they would like to see in the upcoming release.

Formal DISCUSS thread

We need to send out an email to dev@ proposing a release and reference this thread in the heads up email(see below)

Naming conventions:

Release name: (Major.Minor.Patch)

Branch name: (Major.Minor)

Tag-name: (Major.Minor.Patch)

The time for the day the umbrella issue is created to the release branch point must be at least two weeks in order to give the community a chance to prioritize and commit any last minute features and issues they would like to see in the upcoming release.

The RM should then send the pointer to the umbrella issue along with the tentative timeline for branch point to The RM should then send the pointer to the umbrella issue along with the tentative timeline for branch point to the developer lists (TODO: Also send to users list once we create one). Any work identified as release related that needs to be completed should be added as a subtask of the umbrella issue to allow users to see the overall release progress in one place.

Subject: Work on $release releaserelease X.Y.Z has started

Created a tracking jira (jira#) for the Sentry $release release X.Y.Z and plan to branch tentatively on $date. 
 
What would you like to see included?
Thanks,
$RM

...

Before a release is done, make sure that any issues that are fixed have their fix version setup correctly. Run the following JIRA query to see which resolved issues do not have their fix version set up correctly:
Code Block
project = sentry and resolution = fixed and fixVersion is empty
The result of the above query should be empty. If some issues do show up in this query that have been fixed since the last release, please bulk-edit them to set the fix version to '1.28.0'.

Move the unresolved jiras to the next release

Code Block
project = sentry and fixVersion = X.Y.Z and status not in( resolved, done, Accepted, Closed)

You can also run the following query to make sure that the issues fixed for the to-be-released version look accurate:
Code Block
project = sentry and resolution = fixed and fixVersion = '1X.2Y.0Z'
Finally, check out the output of the JIRA release note tool to see which JIRAs are included in the release, in order to do a sanity check.

...

Preparing branches

Create a release branchbranch

Clone fresh repository copy

Code Block
git clone https://git-wip-us.apache.org/repos/asf/incubator-sentry.git cd sentry

Checkout master branch
Code Block
git checkout master

Check that current HEAD points to commit on which you want to base new release branch. Checkout particular commit if not.

Code Block

git log # Check current branch history. HEAD should point to commit that you want to be base for your release branch
git checkout abcdef123 # Check out particular commit that should be base for release branch if -^

Create new release branch with name "branch-$version"
Code Block
git checkout -b branch-1X.2Y.0Z
Update CHANGELOG in the trunk to indicate the changes going into the new version.
The change list can be swiped from the JIRA release note tool (use the "text" format for the change log). See JIRA Cleanup above to ensure that the release notes generated by this tool are what you are expecting.
RM should update the year of the file "NOTICE.txt".

Remove -SNAPSHOT from the release branch and commit

Code Block

find . -name pom.xml | xargs sed -i "" -e "s/X.Y.0-SNAPSHOT/X.Y.0/"
git add .
git commit -m "SENTRY-mvn versions:set -DnewVersion=X.Y.Z -DgenerateBackupPoms=false
git add .
git commit -m "SENTRY-XXXX: Removing -SNAPSHOT from X.Y release branch"

Check your changes and push new branch to Apache repository. "repository name" is the name of the repository, for example "origin".
Code Block
mvn -U clean package -Pdownload-hadoop git push -Pdist -s <settings.xml> git push <repository name> origin branch-1X.2Y.0Z
Check that branch was correctly propagated to Apache repository.

Prepare the trunk master for next release (TODO: update change log?)

Code Block

git checkout master
find . -name pom.xml | xargs sed -i "" -e "s/1.2.0-SNAPSHOT/1.3.0-SNAPSHOT/"
git add .
git commit -m "SENTRY-mvn versions:set -DnewVersion=<X.Y.Z+1>-SNAPSHOT -DgenerateBackupPoms=false
git add .
git commit -m "SENTRY-XXXX: Preparing for sentry 1.3.0 <Release name> development"
git push origin master:master

Send an email announcing new branch

No Format

To: dev@sentry.incubator.apache.org
Subject: New sentry release branch 1.2.0-X.Y

I've just created new release branch for upcoming <Release name> 1.2.0 incubating release.release.
Please continue committing to master branch as usual.
I'll cherry-pick commits to branch-1X.2.0Y on per needed basis.

Thanks,
$RM

...

Check out release branch
Code Block
git checkout branch-1X.2.0Y

Create tag on this commit to identify precise point where the RC was generated and push this tag to main repository

Code Block

git tag -a release-1X.2Y.0Z -m "Sentry 1X.2Y.0 incubatingZ release"
git push origin release-1.2.0 
#Make sure compiles/tests run fine and rat check is fine
mvn clean install -DskipTests -Pdist
mvn test
mvn verify -DskipTests (to do the rat check)
git push origin release-X.Y.Z

If an rc1, rc2, etc is needed, delete that tag before creating a new one:
Code Block
git tag -d release-1X.2Y.0Z git push origin :refs/tags/release-1X.2Y.0Z
Create temporary directory where you'll be preparing all required artifacts
Code Block
mkdir -p /tmp/sentry-release-preparations

Create source artifact and move it to your temporary directory (TODO: git archiveverify?)

Code Block
mvngit clean verify package mv sentry-dist/target/archive --format=tar --prefix=apache-sentry-1X.2Y.0-incubating-src.tar.gzZ-src/ HEAD \| gzip > /tmp/sentry-release-preparations

Sanity Check

Check out the candidate

Code Block
git checkout release/apache-sentry-X.Y.Z

Generate a tarball
Code Block
mvn clean install -DskipTests
-src.tar.gz

Sanity Check

Make sure the tar and the rc match Unpack the source tarball

Code Block
cd /tmp/sentry-release-dist/targetpreparations rmtar -rfxvf ./apache-sentry-1X.2Y.0-incubatingZ-src .tar.gz xzvf apache-sentry-1.2.0-incubating-src.tar.gz

Do another full build inside the source tarball. This time, allow all unit tests & integration tests to run and also include the docs

Code Block

mvn clean install -DskipTestscd

#Do a fresh clone of the tag
git clone https://git-wip-us.apache.org/repos/asf/sentry.git
cd sentry/
git checkout tags/release-X.Y.Z
cd ..
diff -r sentry apache-sentry-1X.2Y.0-incubating-srcmvn test

Signatures and Checksums

All artifacts must be signed and checksummed. In order to sign a release you will need a PGP key. You should get your key signed by a few other people. You will also need to recv their keys from a public key server. See the Apache release signing page for more details. If you add your PGP key fingerprint to your Apache profile, your key should automatically be added to https://people.apache.org/keys/group/sentry.asc

Create signatures and check sums (TODO: Use maven gpg plugin?)

1. Change your working directory to the temporal one

Code Block
cd /tmp/sentry-release-preparations

2. Sing each file with your key

Code Block
for file in *.tar.gz; do gpg --armor --output $file.asc --detach-sig $file; done

3. You can immediately verify your signature

Code Block
for file in *.tar.gz; do gpg --verify $file.asc $file; done

4. Create md5 check sum

Code Block
for file in *.tar.gz; do md5sum $file > $file.md5; done

5. Create sha1 check sum

Code Block
for file in *.tar.gz; do sha1sum $file > $file.sha; done

6. Upload artifacts and all created check sums with signatures to your own web-space on people.apache.org

Code Block
ssh people.apache.org "mkdir -p ~/public_html/sentry-1.2.0-rc0" scp * people.apache.org:~/public_html/sentry-1.2.0-rc0

Some more things to verify before sending out an email

Verify Signatures and hashes
Verify DISCLAIMER, NOTICE and LICENCE (year etc)
Should be in format apache-$project-$version-incubating.tar.gz
All source file have correct headers (Rat check should be clean - mvn verify)
No jar files or the like in the release
Can compile successfully from source
git tag matches the released bits (diff -rf)

Running the vote

Call for sentry dev list votes

Send an email to dev@ list followed by general@incubator. For example,

Z-src

Make sure code compiles and tests pass on the untared src.

Code Block
cd apache-sentry-X.Y.Z-src mvn clean install -DskipTests -Pdist mvn test mvn verify -DskipTests (to do the rat check)

3. You can immediately verify your signature

Code Block
for file in *.tar.gz; do gpg --verify $file.asc $file; done

4. Create sha512 check sum as sha1 is no longer safe

Code Block
for file in *.tar.gz; do sha512sum $file > $file.sha512; done

Upload artifacts

Upload artifacts and all created check sums with signatures to https://dist.apache.org/repos/dist/dev/sentry

1. Install svn client "yum install subversion" more details in https://tecadmin.net/install-subversion-1-8-on-centos-rhel/

2. Checkout the content from "https://dist.apache.org/repos/dist/dev/sentry/". Then create new branch directory, add binary files and source files. Then commit them to repository server.

Code Block
svn checkout https://dist.apache.org/repos/dist/dev/sentry/ <local path> svn mkdir X.Y.Z svn add <file_name> svn commit -m 'commit message'

Update KEYS file

Only PMC can change the KEYS file.

If your PGP key is not yet in the project's KEYS file, you need to first add that in. To do this, checkout the KEYS file and update it using the following commands:

$ svn co https://dist.apache.org/repos/dist/release/sentry sentry-release
$ cd sentry-release
$ (gpg --list-sigs <KEY-ID> && gpg --armor --export <KEY-ID> ) >> KEYS
$ svn commit -m "Adding PGP public key to KEYS file" KEYS

Once this file has been updated, you need to publish it in the appropriate dist directory for the project on http://www.apache.org/dist. To do this, you must copy the file as follows:

$ scp KEYS people.apache.org:/www/www.apache.org/dist/sentry/KEYS

This will take some time to propagate in which you can continue with the other steps of the release process.

Publishing Apache Sentry artifacts to maven central

1. Checkout the relevant git tag, e.g. git checkout release-1.8.0

2. Make sure you have an entry in your ~/.m2/settings.xml with id "apache.staging.https" with your Apache username + password, e.g.:

<id>apache.releases.https</id>

</server>

<id>apache.staging.https</id>

</server>

</servers>

</settings>

3. Deploy the release with: mvn clean deploy -Psign-artifacts

4. Go to https://repository.apache.org/ and log in using your Apache username + password.

5. Click on "Staging Repositories" on the left hand side.

6. Select the entry that starts with orgapachesentry and click on "close". If "close" fails, repeat Step 3-5.

7. Verify via the URL that should appear after refresh that the artifacts look as expected.

8. Run vote. The detail on running vote is in section "Running the vote"

9. After approval, click on "release".

Verifying a release candidate

Following are the typical things we need to verify before voting on a release candidate. And the release manager should verify them too before calling out a vote.

Make sure RCs are hosted @ https://dist.apache.org/repos/dist/dev/sentry
Should be in format apache-$project-$version.tar.gz
Verify Signatures and hashes. You may have to import the public key of the release manager to verify the signatures. (gpg --recv-key <last8 of public key>)
git tag matches the released bits (diff -rf)
Can compile successfully from source
Verify NOTICE.txt file has right content (current year etc)
All files have correct headers (Rat check should be clean - mvn verify)
- Make sure there are no conflicting licenses (TODO: how)
No jar files or the like in the release

You need to close the release in JIRA so that everyone knows that your version should not be used as "fixVersion" for new bugs. You must be a Jira administrator or a project administrator to do the Jira Software tasks on this page. Sentry PM should have this access.

Go to JIRA "Administer project" page and follow "Versions" in left menu. Table with list of all releases should appear, click on additional menu on the right of your release and choose "Release" option. Submit release date and you're done.

...

In order to release you have to checkout release repository located on https://dist.apache.org/repos/dist/release/incubator/sentry/ and add release artifacts there. Only Sentry PMC can do this.

Disclaimer
Apache Sentry is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

Preparing Branch for Future Maintenance Release

After the release has been completed, prepare the branch for the next development cycle.

Check out the release branch with:

git clone https://git-wip-us.apache.org/repos/asf/sentry.git

cd sentry

git checkout branch-X.Y

Increment the version property value in all pom.xml files and add the SNAPSHOT suffix. For example, if the released version was 0.7.0, the new value should be 0.7.1-SNAPSHOT. Please note that the SNAPSHOT suffix is required in order to indicate that this is an unreleased development branch. Use Maven's Versions plugin to do this as follows:
mvn versions:set -DnewVersion=0.7.1-SNAPSHOT -DgenerateBackupPoms=false
Verify that the build is working with changes.
Commit these changes with a comment "Preparing for X.Y.Z+1 development".
Add the release to the downloads
