Steps to Call Python method in BuildBot

Question

I'm trying to implement the build process from master.cfg in BuildBot

I created common utility python packages which can be used while build-process,

So while adding steps in util.BuildFactory() I want to execute the python methods from my custom build-package.

I refereed the Adding customized functions to Buildbot.

I imported my custom package into master.cfg in buildbot, but still can not call this method directly with factory.addStep.

I tried another alternative, created a python script, import the custom-build utility package, and then run this script with steps.ShellCommand (command = ['python', 'myScript.py'])

But there will be additional script maintains for particular build process and I can't reuse that script.

Can anyone show me how to call python method from build process of buildbot.

Answer 1

To run python code, you must write a  custom build step, a class inherited from BuildStep with a code in the run () method. Note that this code will be run in the master (as well as ShellCommand questions). To run the slave code, you must use RemoteShellCommand. See the documents for details.

Answer 2

BuildSteps are usually specified in the buildmaster’s configuration file, in a list that goes into the BuildFactory. The BuildStep instances in this list are used as templates to construct new independent copies for each build (so that state can be kept on the BuildStep in one build without affecting a later build).

For detailed explaination have a look at this blog.

I was also facing same issue how to call python file from buildbot. Following link where I have shared the commands to install buildbot as well as whole master.cfg file
