Release Procedures¶
Table of Contents
Introduction¶
Kurento as a project spans across a multitude of different technologies and languages, each of them with their sets of conventions and best practices. This document aims to summarize all release procedures that apply to each one of the modules that compose the Kurento project. The main form of categorization is by technology type: C/C++ based modules, Java modules, JavaScript modules, and others.
General considerations¶
Lists of projects in this document are sorted according to the repository lists given in Code repositories.
Kurento projects to be released have supposedly been under development, and will have development version numbers:
In Java (Maven) projects, development versions are indicated by the suffix
-SNAPSHOTafter the version number. Example:1.0.0-SNAPSHOT.In C/C++ (CMake) projects, development versions are indicated by the suffix
-devafter the version number. Example:1.0.0-dev.
These suffixes must be removed for release, and then recovered again to resume development.
All dependencies to development versions will be changed to a release version during the release procedure. Concerning people will be asked to choose an appropriate release version for each development dependency.
Tags are named with the version number of the release. Example:
1.0.0.Contrary to the project version, the Debian package versions don’t contain development suffixes, and should always be of the form
1.0.0-0kurento1:The first part (1.0.0) is the project’s base version number.
The second part (0kurento1) is the Debian package revision:
The number prefix (in this example: 0) indicates the version relative to other same-name packages provided by the base system. When this number is 0, it means that the package is original and only exists in Kurento, not in Debian or Ubuntu itself. This is typically the case for the projects owned or forked for the Kurento project.
The number suffix (in this example: 1) means the number of times the same package has been re-packaged and re-published. 1 means that this is the first time a given project version was packaged.
Example:
Imagine that version 1.0.0 of your code is released for the first time. The full Debian package version will be: 1.0.0-0kurento1. Later, you realize the package doesn’t install correctly in some machines, because of a bug in the package’s post-install script. You fix it, and now it’s time to re-publish! But the project’s source code itself has not changed at all, only the packaging files (in
/debian/dir); thus, the base version will remain 1.0.0, and only the Debian revision needs to change. The new package’s full version will be 1.0.0-0kurento2.
Please check the Debian Policy Manual and this Ask Ubuntu answer for more information about the package versions.
Kurento uses Semantic Versioning. Whenever you need to decide what is going to be the final release version for a new release, try to follow the SemVer guidelines:
Given a version number MAJOR.MINOR.PATCH, increment the: 1. MAJOR version when you make incompatible API changes, 2. MINOR version when you add functionality in a backwards-compatible manner, and 3. PATCH version when you make backwards-compatible bug fixes.
Please refer to https://semver.org/ for more information.
Example:
If the last Kurento release was 1.0.0, then the next development version would be 1.0.1-dev (or 1.0.1-SNAPSHOT for Java components).
Later, the time comes to release this new development. If the new code only includes bug fixes and patches, then the version number 1.0.1 is already good. However, maybe this new release ended up including new functionality, which according to Semantic Versioning should be accompanied with a bump in the .MINOR version number, so the next release version number should be 1.1.0. The Debian package version is reset accordingly, so the full Debian version is 1.1.0-0kurento1.
If you are re-packaging an already published version, without changes in the project’s code itself, then just increment the Debian package revision: 0kurento1 becomes 0kurento2, and so on.
Note
Made a mistake? Don’t panic!
Do not be afraid of applying some Git magic to solve mistakes during the release process. Here are some which can be useful:
How to remove a release tag?
Remove the local tag:
git tag --delete <TagName>
Remove the remote tag:
git push --delete origin <TagName>
How to push just a local tag?
git push origin <TagName>
How to amend a commit and push it again?
See: https://www.atlassian.com/git/tutorials/rewriting-history#git-commit–amend
# <Remove Tag> # <Amend> # <Create Tag> git push --force origin <TagName>
Warning
As of this writing, there is a mix of methods in the CI scripts (adm-scripts) when it comes to handle the release versions. The instructions in this document favor creating and pushing git tags manually in the developer’s computer, however some projects also make use of the script kurento_check_version.sh, which tries to detect when a project’s version is not a development snapshot, then creates and pushes a git tag automatically. However if the tag already exists (created manually by the developer), then the git tag command fails, and this script prints a warning message before continuing with its work.
We’ve been toying with different methodologies between handling the tags automatically in CI or handling them manually by the developer before releasing new versions; both of these methods have pros and cons. For example, if tags are handled manually by the developer, solving mistakes in the release process becomes simpler because there are no surprises from CI creating tags inadvertently; on the other hand, leaving them to be created by CI seems to simplify a bit the release process, but not really by a big margin.
Fork Repositories¶

Release order:
Release steps¶
Choose the final release version, following the SemVer guidelines as explained in General considerations.
Set the new version. This operation might vary between projects.
# Change here. NEW_VERSION="<ReleaseVersion>" # Eg.: 1.0.0 NEW_DEBIAN="<DebianRevision>" # Eg.: 0kurento1 function do_release { local PACKAGE_VERSION="${NEW_VERSION}-${NEW_DEBIAN}" local COMMIT_MSG="Prepare release $PACKAGE_VERSION" local SNAPSHOT_ENTRY="* UNRELEASED" local RELEASE_ENTRY="* $COMMIT_MSG" gbp dch \ --ignore-branch \ --git-author \ --spawn-editor never \ --new-version "$PACKAGE_VERSION" \ \ --release \ --distribution "testing" \ --force-distribution \ \ debian/ \ || { echo "ERROR: Command failed: gbp dch"; return 1; } # First appearance of "UNRELEASED": Put our commit message sed -i "0,/${SNAPSHOT_ENTRY}/{s/${SNAPSHOT_ENTRY}/${RELEASE_ENTRY}/}" \ debian/changelog \ || { echo "ERROR: Command failed: sed"; return 2; } # Remaining appearances of "UNRELEASED" (if any): Delete line sed -i "/${SNAPSHOT_ENTRY}/d" \ debian/changelog \ || { echo "ERROR: Command failed: sed"; return 3; } git add debian/changelog \ && git commit -m "$COMMIT_MSG" \ || { echo "ERROR: Command failed: git"; return 4; } gbp tag \ && gbp push \ || { echo "ERROR: Command failed: gbp"; return 5; } echo "Done!" } # Run in a subshell where all commands are traced. (set -o xtrace; do_release)
Follow on with releasing Kurento Media Server.
New Development¶
After the whole release has been completed, bump to a new development version. Do this by incrementing the Debian revision number.
The version number (as opposed to the Debian revision) is only changed when the fork gets updated from upstream sources. Meanwhile, we only update the Debian revision.
# Change here.
NEW_VERSION="<NextVersion>" # Eg.: 1.0.1
NEW_DEBIAN="<DebianRevision>" # Eg.: 0kurento1
function do_release {
local PACKAGE_VERSION="${NEW_VERSION}-${NEW_DEBIAN}"
local COMMIT_MSG="Bump development version to $PACKAGE_VERSION"

|| { echo "ERROR: Command failed: gbp dch"; return 1; }
git add debian/changelog \
&& git commit -m "$COMMIT_MSG" \

gbp tag \
&& gbp push \
|| { echo "ERROR: Command failed: gbp"; return 3; }
echo "Done!"
}
# Run in a subshell where all commands are traced.
(set -o xtrace; do_release)
Kurento Media Server¶
All KMS projects:
Projects that are part of Kurento Media Server¶
Release order:
Preparation: Kurento Module Creator¶
If kurento-maven-plugin is going to get also a new release, then edit the file kurento-module-creator/src/main/templates/maven/model_pom_xml.ftl to update the plugin version in the auto-generation template:
<groupId>org.kurento</groupId>
<artifactId>kurento-maven-plugin</artifactId>
- <version>1.0.0</version>
+ <version>1.1.0</version>
If kurento-parent-pom (from kurento-java) has changed and the Java API artifacts should depend on newer versions, then edit the file kurento-module-creator/src/main/templates/maven/model_pom_xml.ftl to update the parent version in the auto-generation template:
<!-- Maven coordinates -->
<parent>
<groupId>org.kurento</groupId>
<artifactId>kurento-parent-pom</artifactId>
- <version>1.0.0</version>
+ <version>1.1.0</version>
</parent>
Then proceed with the normal release.
Preparation: KMS API Java modules¶
Test the KMS API Java module generation (local check).
apt-get update && apt-get install --no-install-recommends \
kurento-module-creator \
kms-cmake-utils \
kms-jsonrpc-dev \
kms-core-dev \
kms-elements-dev \
kms-filters-dev
cd kms-omni-build
function do_release {
local PROJECTS=(
kms-core
kms-elements
kms-filters
)
for PROJECT in "${PROJECTS[@]}"; do
pushd "$PROJECT" || { echo "ERROR: Command failed: pushd"; return 1; }
mkdir build \
&& cd build \
&& cmake .. -DGENERATE_JAVA_CLIENT_PROJECT=TRUE -DDISABLE_LIBRARIES_GENERATION=TRUE \
&& cd java \
&& mvn clean install -DskipTests=false \
|| { echo "ERROR: Command failed"; return 1; }
popd
done
echo "Done!"
}
# Run in a subshell where all commands are traced.
(set -o xtrace; do_release)
Release steps¶
Choose the final release version, following the SemVer guidelines as explained in General considerations.
Set the new version. This operation might vary between projects.
Commit and tag as needed.
Start the KMS CI job with the parameters JOB_RELEASE ENABLED and JOB_ONLY_KMS DISABLED.
The KMS CI job is a Jenkins MultiJob Project. If it fails at any stage, after fixing the cause of the error there is no need to start the job again from the beginning. Instead, you can resume the build from the point it was before the failure.
For this, just open the latest build number that failed (with a red marker in the Build History panel at the left of the job page); in the description of the build, the action Resume build is available on the left side.
Wait until all packages get created and published correctly. Fix any issues that might appear.
All-In-One script:
# Change here.
NEW_VERSION="<ReleaseVersion>" # Eg.: 1.0.0
NEW_DEBIAN="<DebianRevision>" # Eg.: 0kurento1
cd kms-omni-build/
# Set the new version.
./bin/set-versions.sh "$NEW_VERSION" --debian "$NEW_DEBIAN" \
--release --commit --tag
# Push committed changes.
git submodule foreach 'git push --follow-tags'
git push --follow-tags
Post-Release¶
When all repos have been released, and CI jobs have finished successfully:
Check that the Auto-Generated API Client JavaScript repos have been updated (which should happen as part of the CI jobs for all Kurento Media Server modules that contain KMD API Definition files,
*.kmd):Open the Nexus Sonatype Staging Repositories section.
Select kurento repository.
Inspect Content to ensure they are as expected:
kurento-module-creator
kms-api-core
kms-api-elements
kms-api-filters
All of them must appear in the correct version,
$NEW_VERSION.
Close repository.
Wait a bit.
Refresh.
Release repository.
Maven artifacts will be available within 30 minutes.
Also, check that the JavaScript modules have been published by CI:
Open each module’s page in NPM, and check that the latest version corresponds to the current release:
NPM: kurento-client-core
If any of these are missing, it’s probably due to the CI job not running (because the project didn’t really contain any code difference from the previous version… happens sometimes when not all repos have changed since the last release). Open CI and run the jobs manually:
New Development¶
After the whole release has been completed, bump to a new development version. Do this by incrementing the .PATCH number and resetting the Debian revision to 1.
All-In-One script:
# Change here.
NEW_VERSION="<NextVersion>" # Eg.: 1.0.1
NEW_DEBIAN="<DebianRevision>" # Eg.: 0kurento1
cd kms-omni-build/
# Set the new version.
./bin/set-versions.sh "$NEW_VERSION" --debian "$NEW_DEBIAN" \
--new-development --commit
# Push committed changes.
git submodule foreach 'git push'
Then start the KMS CI job with the parameters JOB_RELEASE DISABLED and JOB_ONLY_KMS DISABLED.
Kurento JavaScript client¶
Release order:
Release steps¶
Choose the final release version, following the SemVer guidelines as explained in General considerations.
Check there are no uncommitted files.
Check latest changes from the main branch.
Set the new version. This operation might vary between projects.
Check there are no development versions in any of the dependencies.
Test the build. Make sure the code is in a working state.
The most common issue is that the code is not properly formatted. To manually run the beautifier, do this:
npm install # To run beautifier over all files, modifying in-place: node_modules/.bin/grunt jsbeautifier::default # To run beautifier over a specific file: node_modules/.bin/grunt jsbeautifier::file:<FilePath>.js
Commit and tag as needed.

Post-Release¶
When all repos have been released, and CI jobs have finished successfully:
Open the Nexus Sonatype Staging Repositories section.
Select kurento repository.
Inspect Content to ensure they are as expected:

Kurento Java client¶
Release order:
Preparation: kurento-java¶
If there have been changes in the API of Kurento Media Server modules (in the .kmd JSON files), update the corresponding versions in kurento-parent-pom/pom.xml:
<version.kurento-chroma>1.1.0</version.kurento-chroma>
<version.kurento-crowddetector>1.1.0</version.kurento-crowddetector>
<version.kurento-markerdetector>1.1.0</version.kurento-markerdetector>
<version.kurento-platedetector>1.1.0</version.kurento-platedetector>
<version.kurento-pointerdetector>1.1.0</version.kurento-pointerdetector>
<version.kurento-utils-js>1.1.0</version.kurento-utils-js>
<version.kurento-maven-plugin>1.1.0</version.kurento-maven-plugin>
Doing this ensures that the Java client gets generated according to the latest versions of the API definitions.
Release steps¶
Choose the final release version, following the SemVer guidelines as explained in General considerations.
Check there are no uncommitted files.
Check latest changes from the main branch.
Set the new version. This operation might vary between projects.
Order matters. kurento-tutorial-java and kurento-tutorial-test require that kurento-java has been installed locally (with
mvn install) before being able to change their version numbers programmatically with Maven.Check there are no development versions in any of the dependencies.
In kurento-java, all dependencies are defined as properties in the file
kurento-parent-pom/pom.xml.Test the build. Make sure the code is in a working state.
The profile ‘kurento-release’ is used to enforce no development versions are present.
Commit and tag as needed.

Close repository.
Wait a bit.
Refresh.
Release repository.
Maven artifacts will be available within 30 minutes.
New Development¶
Warning
You should wait for a full nightly run of the Kurento Media Server pipeline, so the next development packages become available from KMS API modules: kms-api-core, kms-api-elements, and kms-api-filters. This way, the properties in kurento-parent-pom/pom.xml will get updated to the latest SNAPSHOT version.
After the whole release has been completed, bump to a new development version. Do this by incrementing the .PATCH number.

}
# Run in a subshell where all commands are traced.
(set -o xtrace; do_release)
Docker images¶
A new set of development images is deployed to Kurento Docker Hub on each nightly build. Besides, a release version will be published as part of the CI jobs chain when the KMS CI job is triggered.
The repository kurento-docker contains Dockerfile*s for all the `Kurento Docker images`_, however this repo shouldn’t be tagged, because it is essentially a “multi-repo” and the tags would be meaningless (because *which one of the sub-dirs would the tag apply to?).
Kurento documentation¶
The documentation scripts will download both Java and JavaScript clients, generate HTML Javadoc / Jsdoc pages from them, and embed everything into a static section.
For this reason, the documentation must be built only after all the other modules have been released.
Write the Release Notes in
doc-kurento/source/project/relnotes/.Ensure that the whole nightly CI chain works:
Job doc-kurento -> job doc-kurento-readthedocs -> New build at Read the Docs.
Edit VERSIONS.env to set all relevant version numbers: version of the documentation itself, and all referred modules and client libraries.
These numbers can be different because not all of the Kurento projects are necessarily released with the same frequency. Check each one of the Kurento repositories to verify what is the latest version of each one, and put it in the corresponding variable:
[VERSION_DOC]: The docs version shown to readers. Normally same as[VERSION_KMS].[VERSION_KMS]: Repo kurento-media-server.[VERSION_CLIENT_JAVA]: Repo kurento-java.[VERSION_CLIENT_JS]: Repo kurento-client-js.[VERSION_UTILS_JS]: Repo kurento-utils-js.[VERSION_TUTORIAL_JAVA]: Repo kurento-tutorial-java.[VERSION_TUTORIAL_JS]: Repo kurento-tutorial-js.[VERSION_TUTORIAL_NODE]: Repo kurento-tutorial-node.
In VERSIONS.env, set VERSION_RELEASE to true. Remember to set it again to false after the release, when starting a new development iteration.
Test the build locally, check everything works.
make html
Note that the JavaDoc and JsDoc pages won’t be generated locally if you don’t have your system prepared to do so; also there are some Sphinx constructs or plugins that might fail if you don’t have them ready to use, but the Read the Docs servers have them so they should end up working fine.
Git add, commit, and push. Trigger a nightly build, where you can check the result of the documentation builds to have an idea of how the final release build will end up looking like, at https://doc-kurento.readthedocs.io/en/latest/.
# `--all` to include possibly deleted files. git add --all \ VERSIONS.env \ source/project/relnotes/ \ && git commit -m "$COMMIT_MSG" \ && git push \ || echo "ERROR: Command failed: git"
Run the doc-kurento CI job with the parameter JOB_RELEASE ENABLED.
CI automatically tags Release versions in both Read the Docs source repos doc-kurento and doc-kurento-readthedocs, so the release will show up in the Read the Docs dashboard.
Note
If you made a mistake and want to re-create the git tag with a different commit, remember that the re-tagging must be done manually in both doc-kurento and doc-kurento-readthedocs repos. Read the Docs CI servers will read the latter one to obtain the documentation sources and release tags.
Open Read the Docs Builds. If the new version hasn’t been detected and built, do it manually: use the Build Version button to force a build of the latest version. Doing this, Read the Docs will “realize” that there is a new tagged release version of the documentation in the doc-kurento-readthedocs repo.
AFTER THE WHOLE RELEASE HAS BEEN COMPLETED: Set VERSION_RELEASE to false. Now, create a Release Notes document template where to write changes that will accumulate for the next release.
