[ADO] [Repo] - Support for git push atomic

Question

When trying to push a commit and tag simultaneously, i get a failure that the server doesn't support atomic push:

$ git push --atomic origin [branch] [tag]
fatal: the receiving end does not support --atomic push
fatal: the remote end hung up unexpectedly

Support for atomic operations was added in git 2.4 (10 years ago). I am running ADO AzureDevOps_M254_20250410.4.

• Is there a way to correlate the git server version with the ADO version?
• Is there a way to explicitly check git server version ADO Repos?
• Is there a way to check the a git server configuration setting: git config receive.advertiseatomic
• Is there a way to change at git server configuration setting that's not supported in the web interface?

Hi @cj8scrambler,

Azure DevOps Repos currently does not support atomic Git pushes (git push --atomic), That's why you're encountering the issue.

Refer this Developer community doc to know more about the issue.

This is because,

• Azure DevOps uses a custom Git server that doesn’t advertise support for --atomic, even though atomic push has been in Git since v2.4.
• There is no way to check the Git server version or server config (receive.advertiseatomic) in Azure DevOps.
• Azure DevOps does not allow changing low-level Git server settings, even on self-hosted/on-prem environments.

If you want to use atomic like behavior,

• Run the below commands

Push the branch:

git push origin branch

Then push the tag:

git push origin tag || git push origin :branch

This way, if tag push fails, the branch is rolled back.

• You can also use GitHub, GitLab that fully supports atomic pushes if that's a blocker.
