Beginning with Jenkins 2.279 and Jenkins 2.263.4, the Jenkins project is upgrading the base operating system and Java version used in the jenkins/jenkins:latest and jenkins/jenkins:lts images. The update replaces OpenJDK 8u242 with AdoptOpenJDK 8u282 and replaces Debian 9 ("Stretch") with Debian 10 ("Buster"). Why? We’re changing the base image so that we have a better supported operating system and a more current Java release for Jenkins controllers. Better...

Hello everyone, This is the final blog post for the Custom Distribution Service project during the Google Summer of Code timeline. I have mixed feelings since we are almost near the finish line for one of the most amazing open source programs out there. However, it is time to wrap things up for this project and achieve a state where the project can be built upon and...

Since the beginning of the project, the core value which drove its progress was "To enhance the user experience for running Jenkins jobs by reducing the overall execution time". To achieve this goal, we laid out a path: Compare the two existing git implementations i.e CliGitAPIImpl and JGitAPIImpl using performance benchmarking Use the results to create a feature which would improve the overall performance of git plugin Also,...

Hello everyone, It is time to wrap up another successfull phase for the custom distribution service project, and we have incorporated most of the features that we had planned at the start of the phase. It has been an immense learning curve for me and the entire team. To understand what the project is about and the past progress, please refer to the phase one blogpost here. Front-End Filters for Plugins In...

The second phase of the Git Plugin Performance Improvement project has been great in terms of the progress we have achieved in implementing performance improvement insights derived from the phase one JMH micro-benchmark experiments. What we’ve learned so far in this project is that a git fetch is highly correlated to the size of the remote repository. In order to make fetch improvements in this plugin,...

Hello, After an eventful community bonding period we finally entered into the coding phase. This blog post will summarize the work done till the midterm of the coding phases i.e. week 6. If some of the topics here require a more detailed explanation, I will write a separate blog post. These blogs posts will not have a very defined format but would cover all of...

Git Plugin Performance Improvement is a Google Summer of Code 2020 project. It aims to improve the performance of the git plugin, which provides fundamental git functionalities. Internally, the plugin provides these functionalities using two implementations: command line git and JGit (pure java implementation). CLI git is the default implementation for the plugin, a user can switch to JGit if needed The project is divided into two parallel...
