Log:
[Fix JENKINS-29482] Don't hide build history when prune stale branches is on

Reverts "prune deleted branches from BuildData to avoid growing memory consumption"

This reverts the bulk of commit 163e60fccd5a08199efd7d85b0b351c6e950c2f7.
The two test cases which were added are still retained, though it is odd
that they are unaffected by reverting the change to the production code.
As far as I can tell, the BuildData.purgeStaleBranches method was not
called by any test, even though it seems it should have been called.

Fix included in git plugin 2.4.0 released 18 July 2015

Log:
[Fix JENKINS-29482] remove branches in BuildData history which doesn’t exist on remote repo (anymore)

Broken again in git plugin 2.4.1, git client plugin 1.19.1.

The reproduction steps are the same as in the original bug description.

Apparently, the GIT_PREVIOUS_COMMIT is always empty after the first build with eabled pruning and hence no change log is computed further on.

Following are the logs of three consecutive builds. The pruning feature was enabled after the first build.

Log:
[Fix JENKINS-29482] Don't prune stale branches from BuildData

This reverts commit c1872d038cc2f584bafbc375744deb54a1dbe316.

Git plugin 2.4.1 included c1872d0 which regressed the plugin and
introduced JENKINS-32218

Fixed in git plugin 2.4.2 - released 2 Feb 2016

Reproduced on git plugin 2.4.2. See screenshot.

vikulin, your screen shots show that you can't be seeing this bug, because you have not enabled "Prune stale branches" in the git plugin "Additional Behaviours" section. You may have found another case where history is not shown, but the case you're reporting can't be related to "Prune stale branches", unless your screen shots somehow do not match how you've configured the job.

If you're not seeing history, please submit a new bug report with a detailed, numbered list of the steps you take to duplicate the problem. Reopening an existing bug confuses things, since you seem to have reopened this bug report without realizing that the detailed steps included in the report do not match your steps. Refer to step 9, ""Reconfigure the job to prune stale remote tracking branches", which seems to not be used in your screen shots.

I'm closing this bug again, assuming you'll submit a new bug.

markewaite, I enabled "Prune stale branches" and still no history appears.

vikulin, I can't duplicate the problem you're reporting. I tried several different variants based on guesses from the screenshots you included. All of them correctly showed recent changes.

Steps I took to try to duplicate the problem included:

1. Define a new freestyle project named "JENKINS-29482-parameterized-checkout-subdir-blocks-history"
2. Parameterize the build, with a "Choice" parameter named "BRANCH". Assign the first value (default) as "JENKINS-29482" and other values based on branches in the source repository (I also tried a git parameter using the git parameter plugin with the same results)
3. Use git as the source control, with repository URL https://github.com/MarkEWaite/JENKINS-26197.git
4. Use "*/$BRANCH" as the "Branch to build"
5. Add "$BRANCH/src" as the "Local subdirectory for repo" for the additional behaviour "Checkout to a sub-directory"
6. Add "Clean before checkout" as an additional behaviour
7. Add "Prune stale remote tracking branches" as an additional behaviour
8. Enable "Poll SCM" (schedule is optional, since I have the "Poll Now" plugin available on my Jenkins)
9. Save the job and click the "Poll Now" link to poll for changes

Once the job definition has been saved and run once, then I submit changes to that repository and click "Poll Now". The changes are detected by polling, the job is built, and the "Recent Changes" show the expected values. Each time I submit changes to the repository and then poll, the job runs and changes are correctly shown in the "Recent Changes" page. If there were no changes since the last build, no changes are shown in the "Recent Changes" page.

Please provide step by step instructions that duplicate the bug.

I have no idea why but the history has started appearing. Closing the defect.
