release stabilisation branchThere are both plug-in components and products that are part of the Simantics Release Train that shall be released simultaneously to a major or minor Simantics release.
Plug-in components are installable features that are deployed online as P2 repositories for general availability. Products are deployed as ZIP files and made available online in designated locations on simantics.org.
Core components of the release train:
Plug-in components that are part of the release train:
Products that are part of the release train:
For simplicity, each of these components are versioned accoring to platform versioning, i.e. for Platform SDK 1.26.0 there will be Simantics Desktop 1.26.0, Sysdyn 1.26.0, and so on.
When release stabilisation starts, branch all relevant repositories like this:
git clone ssh://<user>@gerrit.simantics.org:29418/simantics/platform.git
cd platform
git branch release/x.y.z[.w] <commit>
git push origin release/x.y.z[.w]
When creating major/minor releases <commit>
is usually a commit in the master
branch.
With service releases, branch from an existing release/*
branch instead.
Instead of doing this clone+branch+push sequence for every SDK repository separately,
please use the included release-helper.sh
shell script to perform this mechanical work. The script supports many useful basic git commands which all perform the requested operation on all the release train repositories. The operations can be seen from the help text printed by the script when given no arguments:
Usage: release-helper.sh <version> <branch-name> <user-name> clone|branch|checkout|fetch|list-tags|pull|push|push-tags|remove-tag|status|tag
Always begin by cloning all the repositories for working on
./release-helper.sh x.y.z release/x.y.z your-git-username clone
This will create a directory called x.y.z
under the current working directory and clone all the repositories under it. The first <version>
argument is only used for the base working directory x.y.z
. The second <branch-name>
argument tells what branch to specify to the action, i.e. branch
, checkout
, etc.
Branching and pushing the branches to remote happens as follows:
./release-helper.sh x.y.z release/x.y.z your-git-username branch
./release-helper.sh x.y.z release/x.y.z your-git-username checkout
./release-helper.sh x.y.z release/x.y.z your-git-username push
If you're creating a service release x.y.w
from x.y.z
where w > z
, do this:
./release-helper.sh x.y.w release/x.y.z your-git-username clone
./release-helper.sh x.y.w release/x.y.z your-git-username checkout
./release-helper.sh x.y.w release/x.y.w your-git-username branch
./release-helper.sh x.y.w release/x.y.w your-git-username checkout
# Perhaps make modifications to the branch here and commit to each project separately
./release-helper.sh x.y.w release/x.y.w your-git-username push
In release 1.31.0 Simantics started using the wonderful tool from Obeo (https://github.com/mbarbero/fr.obeo.releng.targetplatform) to generate .target
files from .tpd
files which allow much simpler specification of the target contents and also composition of .tpd files via inclusion.
In the following steps, it is recommended to ensure every .target
file is up-to-date by regenerating them from .tpd
files. While doing so, take care to use up-to-date online contents to perform the generation.
.tpd
files in platform repositoryEnsure you've ran
./release-helper.sh x.y.z release/x.y.z your-git-username checkout
to make sure you're working on the release branch before doing anything.
Go into the cloned platform repository at x.y.z/platform
Edit all target platform files in releng/org.simantics.sdk.build.targetdefinition/
, i.e.
org.simantics.sdk.build.targetdefinition.tpd
simantics.tpd
Replace the following rows in both mentioned files:
location "http://www.simantics.org/download/master/external-components/maven" {
location "http://www.simantics.org/download/master/external-components/manual" {
include "http://www.simantics.org/download/master/org.simantics.sdk.build.targetdefinition.tpd"
location "http://www.simantics.org/download/master/sdk" {
with
location "http://www.simantics.org/download/release/x.y.z[.w]/maven" {
location "http://www.simantics.org/download/release/x.y.z[.w]/manual" {
include "http://www.simantics.org/download/release/x.y.z[.w]/org.simantics.sdk.build.targetdefinition.tpd"
location "http://www.simantics.org/download/release/x.y.z[.w]/sdk" {
Edit version number of org.simantics.sdk
feature in features/org.simantics.sdk.feature/feature.xml
to x.y.z
.
<feature
id="org.simantics.sdk"
label="Simantics SDK"
version="x.y.z"
provider-name="VTT Technical Research Centre of Finland">
If the release branch you're setting up is a hotfix-release x.y.z.w
,
don't include the .w
part in this version.
An example of these changes can be seen in gitweb or review 1361.
Ensure that Gitlab has a release engineering issue for the branched release, such as Simantics 1.34.0 release engineering
$version release engineering
.simantics/platform#16
.releng
and $version
to the new issueCommit the changes made
git commit -a
with the commit message
Configured release/x.y.z[.w] branch for SDK builds.
gitlab #xxxx
where #xxxx
is the number of the x.y.z[.w] release engineering issue and push them to remote
git push origin release/x.y.z[.w]
If you are branching from master
, bump the revision of master right now to start the next release cycle in master.
An example of these changes can be seen in gitweb or in review 1362. The changes include:
Commit the changes with the following commit message
Bumped master target and org.simantics.sdk feature versions to x.y.z[.w].
gitlab #yyyy
where #yyyy
is the number of the next release's release engineering issue.
Do the same for simupedia target platform files as was done in task 6. for platform target definitions.
Trigger an execution of the simantics-release-train Jenkins job with parameters
release/x.y.z[.w]
true
to ensure that all components of the release train build fine and to publish first versions of P2 repositories of everything online.
The release train build is currently never ran automatically.
However, after following all these steps, whenever changes are pushed/merged to release/x.y.z[.w]
branch in Gerrit, new Jenkins builds are triggered automatically and they will publish the results (P2 repositories/products) at their designated locations online.
The release train build does two very important steps as the first things, i.e. build the external dependency P2 repositories for both the Platform SDK and Simupedia:
stage('External Dependencies') {
node {
build job: 'SDK/Deploy External Components to Web', parameters: params1
build job: 'Member Components/Simupedia/fi.semantum.simupedia.build.p2.site', parameters: params1
}
}
After that it builds the Platform SDK and Simupedia before building anything else:
stage('SDK') {
node {
build job: 'SDK/Simantics SDK', parameters: params1
// Note that Simantics SDK builds simupedia-git as well
}
}
Documentation to review:
For each wiki page:
Ensure tutorial wiki documentation at http://dev.simantics.org/index.php/Tutorials is up-to-date with the released platform
Ensure tutorial projects and product build properly
com.acme.movie
When the release branches are ready for the release, tag them with the tag vx.y.z[.w]
:
./release-helper.sh x.y.z release/x.y.z your-git-username checkout
./release-helper.sh x.y.z release/x.y.z your-git-username pull
./release-helper.sh x.y.z release/x.y.z your-git-username tag
./release-helper.sh x.y.z release/x.y.z your-git-username push-tags
Note: release-helper.sh will supply the -m argument to git tag to create an annotated tag. Only annotated or signed tags can be pushed to Gerrit.
NOTE: This step is now deprecated since we are in the process of moving all mediawiki-based documentation into the platform git repository.
This step is only necessary for major/minor releases, not for service releases.
The wiki databases to be backed up are:
These are MediaWiki installations. The only sane way to "tag" the documentation is to back up the mysql database backing the wiki. Should the wiki be required at a later time for some reason, we'll put the documentation up then in a separate Mediawiki installation.
