Why is BITBUCKET_COMMIT short all of a sudden?

Joshua Behrens

I have scripts comparing BITBUCKET_COMMIT and git rev-parse. We noticed in a 1yo repository where we now added that kind of script, that BITBUCKET_COMMIT for whatever reason is now only 12 characters long. This way the short revision compared with the long revision from git rev-parse will never be equal again like this. Is this a change where I missed a memo? Which newsletter do I need to subscribe?

Hi Joshua,

Is the build that returns the short hash running on a pull-requests definition?

Builds that run on pull-requests will return a short hash for BITBUCKET_COMMIT. However, builds running on branches, tags, custom pipelines, and the default pipeline will return the full hash for BITBUCKET_COMMIT.

We have a bug report about this in our issue tracker:

• https://jira.atlassian.com/browse/BCLOUD-19393

Workaround:

You can use the following command in the script of that step, prior to using the variable:

- export BITBUCKET_COMMIT=$(git log -1 --format="%H" $BITBUCKET_COMMIT 2>/dev/null)

The variable BITBUCKET_COMMIT will then return the full commit hash.

Kind regards,
Theodora
