How to delete commits from jira issue after git prune or git gc (garbage collection) ?

[Stefan Salzl]

Hi Atlassians,

I´ve got a problem at customer´s site:

The setting is a Jira DC deployment with GitHub Enterprise (self hosted) connected via DVSC.

After deleting commits in GitHub

github-env bin/rake git:gc:all

the commits from the garbage collection still showing in Jira issue´s development information but not working anymore (dead link - opening the link leads to 404)

Is there any way to syncronize garbage collection or the git:gc /git prune ?

Thanks in advance

Best
Stefan

Hi @Stefan Salzl  

Interesting question. From what I know, Jira DC stores development information that it receives from the DVCS integration, and running git gc or git prune on the GitHub side doesn't always trigger a cleanup in Jira. That's why you may still see the commit reference even though the underlying object no longer exists, resulting in a 404.

In case it's helpful, you could try forcing a resynchronization of the DVCS connection or reindexing the development information to see if the stale metadata is refreshed. I'm also curious if anyone has found a supported way to purge these orphaned commit links.

The DVCS connector in Jira Data Center does not automatically detect references to commits that have been removed on the GitHub side. The sync process is additive: it picks up new commits but does not verify whether previously indexed commits still exist in the remote repository.

Here are your options, from least to most disruptive:

1. Try a full soft sync first. Go to Jira Administration > Applications > DVCS Accounts, find the relevant GitHub Enterprise account, and click the sync icon. This is unlikely to remove stale commits but is worth trying as a first step.

2. Remove and re-add the repository (or the entire DVCS organization). This is the most reliable approach. Go to Jira Administration > Applications > DVCS Accounts, remove the connected GitHub Enterprise organization or specific repository, then re-add it. Jira will re-index all development information from scratch based on what currently exists in GitHub, so the garbage-collected commits will no longer appear.

Note that the re-sync can take significant time. Also, before removing the DVCS account, document the old configuration (OAuth credentials, repository list, etc.).
