# Kea Release Process
## Introduction
The Kea release process (for the base version of Kea and the hooks) is different to that of DHCP. At the moment, Kea has only one supported release at a time, so the process tries to ensure that any modifications needed for a release take place on the master branch, rather than on a version-specific one. The basic steps for a release are:
1) Announce a code freeze for the master branch that will last until actual tarball release
2) Do all necessary changes to the master branch for the release
3) Create release tarball from master branch
4) After sanity checks made by the QA and development teams, either we continue or we accept changes on master to fix issues if needed and go back to the previous step.
5) Create a release branch (for beta) or merge master to existing release branch (for final) and tag release on it. (???)
6) Sign and upload tarballs
7) Announce that freeze time on master branch is over.
8) Release tarballs are prepared by Jenkins job: https://jenkins.isc.org/job/kea-master-tarball-internal/. When given tarball is accepted for releasing it is pushed to repo.isc.org using Jenkins job: https://jenkins.isc.org/job/kea-release-upload-internal/
## Pre-Release Preparation
Some of those checks and updates can be made before actual freeze, but it's reasonable to announce freeze now!
- [ ] 1. Check Jenkins results:
* Number of unit tests and system tests failing
* Is there a change in system tests pass rate? *Notify the development team of the overall Jenkins status
* Look into tarball check report " Kea Build Checks" on last tarball build and check if there is nothing suspicious (add/removed files, etc), verify that with developers:
* Compare current release package with code in repository
* Compare current release package with previous release package
- [ ] 2. Is the distcheck passing on kea and kea+premium (https://jenkins.isc.org/job/kea-master-distcheck/)?
* Highlight any issues that require fixing.
- [ ] 3. Check perflab if there is no critical errors there (https://perflab.isc.org/)
- [ ] 4. Make sure that there is no pending ticket to merge! (Use GitLab https://gitlab.isc.org/isc-projects/kea/merge_requests and https://gitlab.isc.org/isc-private/kea-premium/merge_requests or contact the development team).
- [ ] 5. Check the Known Issues list, is there something that suppose to be fixed before release and was omitted?
- [ ] 6. Check versioning:
* Ask the development team if the library versions are being updated (there is a step to check it later).
* Ask the development team if the HOOKS_VERSION is being updated.
- [ ] 7. Create Release Notes on Kea GitLab wiki using standard template, update all dates and versions. This wiki page should created under "release notes" folder, like this one: release-notes-1.5-final
- [ ] 8. Check if there is a Release Checklist ready. If not, create new one using this template (page could have been created, check Releases section at the bottom of this page)
The following steps may involve changing files in the repository. If any files will be updated, create a Kea ticket for them and make the changes on a separate branch.
- [ ] 1. Check User's Guide sections:
* Chapter 1. Introduction
- On what platforms we are running tests using Jenkins? Update Supported Platforms
- Did we add any additional 3rd party software? Update if needed
- Is there a new tool installed in bin or sbin released this time? If yes, is it documented?
* Chapter 2. Quick Start
- Has the default installation process changed (for kea and hooks)? If yes, are those changes documented and highlighted in the release notes?
* Chapter 3. Installation
- Check installation hierarchy
- Check and update Building Requirements
- Check configure options against what ./configure -h says
- [ ] 2. Check !ChangeLog entries in Kea main and premium:
* Spelling, missing numbers, trailing whatspaces? (some of that is checked in every build of tarball-internal Jenkins job)
* Update Release Notes with !ChangeLog entries
- [ ] 3. Check AUTHORS, INSTALL, README files in Kea main and premium.
- [ ] 4. Update information in sources about copyright dates, new version, etc. This is done manually using script https://gitlab.isc.org/isc-private/qa-dhcp/blob/master/kea/build/prepare_kea_release.sh
- [ ] 5. Regenerate parsers using docs.isc.org:
* download kea repo
cd kea; autoreconf -fi; ./configure --with-log4cplus=/home/wlodek/log4cplus --enable-generate-parser (log4cplus in /home/wlodek should be available for everyone, if not - download your own)
export PATH=/home/fdupont/bin:$PATH
cd ~/kea/src/bin/dhcp4; touch *.yy; make parser
cd ~/kea/src/bin/dhcp6; touch *.yy; make parser
cd ~/kea/src/bin/d2; touch *.yy; make parser
cd ~/kea/src/bin/agent; touch *.yy; make parser
cd ~/kea/src/bin/netconf/; touch *.yy; make parser
cd ~/kea/src/lib/eval; touch *.yy; make parser
TODO: we should regenerate all of them or just the one that been modified?
If changes were made, commit the change, push the branch to the main repository and request a review. Once the changes have been approved, merge the branch to master.
## Build selection and upload package
That is the last moment to freeze code!
- [ ] 1. Update release version in configure.ac and remove -git suffix, and commit the change on master. From that moment all tarball builds can be officially released.
- [ ] 2. Go to tarball-internal Jenkins job and pick last tarball build - it will be a release candidate.
- [ ] 3. Tarball checks before requesting sanity checks from dev team
* Download tarballs from picked jenkins build
Untar packages:
* Check sizes - is new package reasonable?
* Check installation tree, compare it with previous release
* Check installed lib versions
* which were updated? (save results)
* any of the lib from current release has lower number then corresponding lib from previous release? (!)
* Uninstall Kea, check what left (there should be just configuration files)
* Check if all of installed binaries has man page
* if not, is it in the tarball?
* are man page up-to-date?
* Check if documentation is properly formatted, has correct versions and dates.
* it's advised to search for previous version numbers, some of them are statically added in statements that are no longer valid
- [ ] 4. If all seems to be ok then upload tarballs to repo.isc.org
* Go to release-upload Jenkins job
* Click "Build with Parameters"
* In field "Tarball" select picked tarball build
* In field "Release_Candidate" pick:
* rc1 if this is the first selected build for release, it will push selected tarballs to repo.isc.org, to folder suffixed with indicated rc#
* next rc# if this is a respin after some fixes (note: it is not possible to pick previous rc number - it will result in error)
* final if the last rc number was ok, this will push selected tarbal to repo.isc.org, to folder with no suffixes
- [ ] 5. If none of the results force you to fix and rebuild package, send sanity check request by an email to dhcp-team@isc.org and qa@isc.org with indicating paths with tarballs on repo.isc.org asking for sanity checks
## Sanity checks proposals:
- [ ] 1. Check documentation:
* users guide:
- dates, versions, installation instructions both for kea and premium, formatting
- if you have time - read as much as you can.
* man pages:
- dates, versions, is it up-to-date? or usage changed between releases?
- does every binary has it's own .8 page?
- [ ] 2. Check tarball content:
* compare tarball against repo (does some of the not included files should actually be included?)
* does premium tarballs include correct hooks? (any missing files?)
- [ ] 3. compile:
* configure warnings?
* build warnings?
- [ ] 4. run unit tests with various db backends, install (check tree), uninstall (check tree)
- [ ] 5. Check example configurations
- [ ] 6. Check release notes (not included in tarball)
- [ ] 8. Check db update scripts:
* tarball inlcude the last one? (compare with repo)
## Releasing tarballs:
- [ ] 1. Write an email to signers@isc.org requesting signatures of final tarballs on repo.isc.org indicating release folders. - Attach SHA256 checksums from tarball-internal logs.
- [ ] 2. Make release branch (e.g. v1_5_0 one branch for beta and final, with tags for both releases)
- [ ] 3. Upload Release Notes to repo.isc.org
- [ ] 4. When release packages are signed then upload them from repo.isc.org to ftp:
* make-available --public --symlink=cur /data/shared/sweng/kea/releases/1.4.0-beta
* make-available --private /data/shared/sweng/kea/releases/premium-1.4.0-beta/
* make-available --private /data/shared/sweng/kea/releases/subscription-1.4.0-beta/
- [ ] 5. Contact support or marketing to upload packages to www.isc.org/downloads
- [ ] 6. Contact marketing to upload premium packages to 'products' in web store
- [ ] 7. Contact support to deliver premium and subscriber-only hooks to Kea support subscribers
- [ ] 8. For final release - Release Notes should contain changlogs since previous stable release (beta +final)
- [ ] 9. Modify Release Notes to Announcement
- fold -sw 73 Kea140betaReleaseNotes.txt > Announcement
- change header
- change ftp links to ww.isc.org/downloads
- send it to yourself to check if it's ok
- [ ] 10. Prepare article on kb.isc.org
- change editing mode to HTML, copy release notes between <pre></pre>
- ask support to publish this document
- [ ] 11. Send announcements on:
* kea-users@lists.isc.org
* kea-announce@lists.isc.org
* dhcp-announce@lists.isc.org
- [ ] 12. Notify marketing to announce via social media, publish any blog post that is planned
* publish any blog post that is planned
* Update kea.isc.org
* Update Wikipedia page release info
* Add new hooks to downloadable products (if applies)
* Update subscription data sheet with any new hook (if applies)
* Inform sales about what the release may mean to them
- [ ] 13. Check KnownIssues list on kea.isc.org https://kea.isc.org/wiki/KeaKnownIssues
- ssh kea.isc.org /var/www/kea-docs
- [ ] 14. update page: https://wiki.isc.org/bin/view/Main/KeaReleaseDates
- [ ] 15. update page: https://wiki.isc.org/bin/view/Main/EngineeringReleaseSchedule

# Kea Contributor's Guide
So you found a bug in Kea or plan to develop an extension and want to send us a patch? Great! This
page will explain how to contribute your changes smoothly.
Here's a quick list of how to contribute a patch:
1. **create account** on [gitlab](https://gitlab.isc.org)
2. **open an issue** in [Kea project](https://gitlab.isc.org/isc-projects/kea/issues/new), make sure
it describes what you want to fix and **why**
3. **ask someone from the ISC team to give you permission to fork Kea** (ask @tomek, @vicky, @ondrej
or @godfryd or basically anyone from the Kea dev team)
4. **fork Kea code**: go to Kea project page, click [Fork button](https://gitlab.isc.org/isc-projects/kea/forks/new).
If you can't, you didn't complete step 3.
5. **Implement your fix or feature, push code** to your repo. Make sure it compiles, has unit-tests,
is documented and does what it's supposed to do.
6. **Open Merge Request**: go to Kea project [merge requests page](https://gitlab.isc.org/isc-projects/kea/merge_requests),
click [New merge request](https://gitlab.isc.org/isc-projects/kea/merge_requests/new). If you
don't see the button, you didn't complete step 3.
7. **Participate in the code review**: Once you submit the MR, someone from ISC will eventually get
to the issue and will review your code. Please make sure you respond to comments. It's likely
you'll be asked to update the code.
For a much more detailed description with details, see the text below.
## Writing a patch
Before you start working on a patch or a new feature, it is a good idea to discuss it first with Kea
developers. You can post your questions to the [kea-dev](https://lists.isc.org/mailman/listinfo/kea-dev)
or [kea-users](https://lists.isc.org/mailman/listinfo/kea-users) mailing lists. The kea-users is
intended for users who are not interested in the internal workings or development details of Kea: it
is OK to ask for feedback regarding new design or the best proposed solution to a certain
problem. This is the best place to get user's feedback. The internal details, questions about the
code and its internals are better asked on kea-dev.
OK, so you have written a patch? Great! Before you submit it, make sure that your code
compiles. This may seem obvious, but there's more to it. You have surely checked that it compiles on
your system, but Kea is a portable software. Besides Linux, it is compiled and used on relatively
uncommon systems like OpenBSD. Will your code compile and work there? What about endianness? It is
likely that you used a regular x86 architecture machine to write your patch, but the software is
expected to run on many other architectures. You may take a look at [system specific build
notes](https://kb.isc.org/docs/installing-kea). For a complete list of systems we build on, you may
take a look at the [Jenkins build farm](https://jenkins.isc.org/).
Does your patch conform to [Kea coding
guidelines](https://gitlab.isc.org/isc-projects/kea/wikis/coding-guidelines)? You can submit a
patch that does not adhere to them, but that will reduce its chances of being accepted. If the
deviations are minor, one of the Kea engineers who does the review will likely fix the issues.
However, if there are lots of issues, the reviewer may simply reject the patch and ask you to fix it
before re-submitting.
## Running unit-tests
One of the ground rules in Kea development is that every piece of code has to be tested. We now have
an extensive set of unit-tests for almost every line of code. Even if you are fixing something
small, like a single line fix, you are encouraged to write unit-tests for that change. That is even
more true for new code: if you write a new function, method or a class, you definitely should write
unit-tests for it.
To ensure that everything is tested, ISC uses a development method called [Test Driven Development
(TDD)](https://en.wikipedia.org/wiki/Test-driven_development). In TDD, a feature is developed
alongside the tests, preferably with the tests being written first. In detail, a test is written for
a small piece of functionality and run against the existing code. (In the case where the test is a
unit test for a function, it would be run against an empty (unimplemented) function.) The test
should fail. A minimal amount of code is then written, just enough to get the test to pass. Then
the process is repeated for the next small piece of functionality. This continues until all the
functionality has been implemented.
This approach has two advantages:
- By writing a test first and then only enough code to pass the test, that code is fully tested. By
repeating this process until the feature is fully implemented, all the code gets test
coverage. You avoid the situation where not enough tests have been written to check all the
- By running the test before the code implementing the function is written and observing the test
fail, you can detect the situation where a bug in the test code will cause it to pass regardless
of the code being tested.
Initially, some people unfamiliar with that approach react with "but my change is simple and I
tested that it works". That approach is both insufficient and short-sighted. It is insufficient,
because manual testing is by definition laborious and can't really be done on the multitude of
systems we run Kea on. It is short-sighted, because even with your best intentions you will not be
able to dedicate any significant amount of time for repeated testing of your improved code. The old
ISC DHCP has two decades of history behind it and we hope to make Kea last similar time span. Over
such long periods, code tends to be refactored several times. The change you made may be affected by
some other change or by the code that hasn't been written yet.
See Building Kea with Unit Tests for instructions on how to run unit-tests. If you happen to touch
any database related code, make sure you compile your code with –with-mysql, –with-pgsql and/or
–with-cql as needed. For example, if you change something substantial, make sure the other
compilation options still work.
If you happen to add new files or have modified any Makefile.am files, it is also a good idea to
check if you haven't broken the distribution process:
make distcheck
There are other useful switches which can be passed to configure. It is always a good idea to use
`–enable-logger-checks`, which does sanity checks on logger parameters. Use `–-enable-debug` to
enable various additional consistency checks that reduce performance but help during development. If
you happen to modify anything in the documentation, use `–-enable-generate-docs`. If you are
modifying DHCP code, you are likely to be interested in enabling a non-default database backends for
DHCP. Note that if the backend is not enabled, the database-specific unit-tests are skipped. To
enable the MySQL backend, use the switch `–with-mysql`; for PostgreSQL, use `–with-pgsql` and for
Cassandra use `--with-cql`. A complete list of all switches can be obtained with the command:
./configure --help
## Submitting Merge Request (also known as sending your patch the right way)
The first step in writing the patch or new feature should be to get the source code from our Git
repository. The procedure is very easy and is [explained
here](https://gitlab.isc.org/isc-projects/kea/wikis/processes/gitlab-howto). While it is possible
to provide a patch against the latest stable release, it makes the review process much easier if it
is for latest code from the Git master branch.
ISC uses [gitlab](https://gitlab.isc.org) to manage its source code. While we also maintain presence
on [github](https://github.com/isc-projects/kea), the process of syncing gitlab to github is mostly
automated and Kea devs rarely look at github.
ISC's gitlab has been a target for spammers in the past, so it is now set up defensively. In
particular, new users can't fork the code on their own and it requires someone from ISC to manually
grant the ability to fork projects. Fortunately, this is easy to do and we glady do this for anyone
who asks and provides a good reason. "I'd like to fix bug X or develop feature Y" is an excellent
reason. The best place for asking is either kea-dev or asking in a comment in your issue. Make sure
you put a name tag (@tomek, @godfryd, @vicky or @ondrej). When you write a comment in an issue or
merge request and add a name tag on it, the user is automatically notified.
Once you fork the Kea code in gitlab, you have your own copy and you can commit your changes there
and push them to your copy of Kea repo. Once you feel that your patch is ready, go to Kea project
and [submit a Merge Request](https://gitlab.isc.org/isc-projects/kea/merge_requests/new).
If you can't access this link or don't see New Merge Request button on the [merge requests
page](https://gitlab.isc.org/isc-projects/kea/merge_requests), please ask on kea-dev and someone
will help you out.
## Send Pull Request on github
If you can't send the patch on gitlab, the next best preferred way is to send pull request (PR) on
This is almost as good as sending MR on gitlab. The downside is that Kea devs don't look at github
too frequently, so it may be a while before we notice it. And when we do, the chances are we will be
busy with other things. With gitlab, your MR will stare at us the whole time, so we'll get round to
it much quicker. But we understand that there are some cases where people may prefer github over
See the excellent documentation on github: https://help.github.com/articles/creating-a-pull-request/
for details. In essence, you need github account (spam/hassle free, takes one minute to set
up). Then you can fork the Kea repository, commit changes to your repo and ask us to pull your
changes into official Kea repository. This has a number of advantages. First, it is made against a
specific code version, which can be easily checked with git log command. Second, this request pops
up instantly on our list of open pull requests and will stay there. The third benefit is that the
pull request mechanism is very flexible. Kea engineers (and other users, too) can comment on it,
attach links, mention other users etc. You as a submitter can augment the patch by committing extra
changes to your repository. Those extra commits will appear instantly in the pull request. This is
really useful during the review. Finally, Kea developers can better assess all open pull requests
and add labels to them, such as "enhancement", "bug", or "unit-tests missing". This makes our life
easier. Oh, and your commits will later be shown as yours in github history. If you care for that
kind of things, once the patch is merged, you'll be automatically listed as contributor and Kea will
be listed as project you have contributed to.
## If you really can't do MR on gitlab or PR on github...
Well, you are out of luck. There are other ways, but those are really awkward and the chances of
your patch being ignored are really high. Anyway, here they are:
- [create an issue in the Kea Gitlab](https://gitlab.isc.org/isc-projects/kea/issues/new) and attach
your patch to it. Sending a patch has a number of disadvantages. First, if you don't specify the
base version against which it was created, one of Kea developers will have to guess that or go
through a series of trials and errors to find that out. If the code doesn't compile, the reviewer
will not know if the patch is broken or maybe it was applied to incorrect base code. Another
frequent problem is that it may be possible that the patch didn't include any new files you have
added. If we happen to have any comments that you as submitter are expected to address (and in
the overwhelming majority of cases, we have), you will be asked to send an updated patch. It is
not uncommon to see several rounds of such reviews, so this can get very complicated very
quickly. Please don't add your issue to any milestone. Kea team has a process of going through
issues unassigned to any milestone. Kea developers review new issues once a week and assign them
to specific milestones. Please do not add issues to working milestones directly. Having an issue
in gitlab ensures that the patch will never be forgotten and it will show up on our gitlab
reports. It's not required, but much appreciated if you send a short note to the kea-dev mailing
list explaining what you did with the code and announce the issue number.
- Send a patch to the kea-dev list. This is the third preferred method, if you can't or don't want
to use gitlab and github. If you send a patch to a mailing list in a wrong time, e.g. shortly
before a release, Kea developers may miss it or perhaps they will see it and then forget about
it. Nevertheless, it is still doable and we successfully accepted patches that way. It just takes
more time from everyone involved, so it's a slower process in general.
- Send a tarball with your modified code. This is really the worst way one can contribute a
patch. It has a number of disadvantages. In particular, someone will need to find out which
version the code was based on and generate the patch. It's not rocket science, but it may be a
very mundane thing to do if the Kea developer does not know the version in advance. The mailing
list has a limit on the message size (for good reasons), so you'll likely need to upload it
somewhere first. Kea developers often don't pick up new issues instantly, so it may have to wait
weeks before the tarball is looked at. The tarball does not benefit from most of the advantages
