For every pushed commit Gerrit verifies that the e-mail address of the author matches one of the registered e-mail addresses of the pushing user. If this is not the case pushing the commit fails with the error message “invalid author”. This policy can be bypassed by having the access right Forge Author.
This error may happen for two reasons:
incorrect configuration of the e-mail address on client or server side
missing privileges to push commits of other authors
If pushing to Gerrit fails with the error message “invalid author” and you are the author of the commit for which the push fails, then either you have not successfully registered this e-mail address for your Gerrit account or the author information of the pushed commit is incorrect.
Check in Gerrit under Settings → Identities which e-mail addresses you’ve configured for your Gerrit account. If no e-mail address is registered go to Settings → Contact Information and register a new e-mail address there. Make sure you confirm your e-mail address by clicking on the link in the e-mail verification mail sent by Gerrit. If you don’t receive the e-mail verification mail it might be that it was caught by your spam filter.
For every commit Git maintains the author. If not explicitly specified Git computes the author on commit out of the Git configuration parameters user.name and user.email.
$ git config -l ... user.name=John Doe firstname.lastname@example.org ...
A commit done with the above Git configuration would have “John Doe <email@example.com>” as author.
You can see the author information for existing commits in the history.
$ git log commit cbe31bdba7d14963eb42f7e1e0eef1fe58698c05 Author: John Doe <firstname.lastname@example.org> Date: Mon Dec 20 15:36:33 2010 +0100 my commit
Check in Git that the author information of the commit that should be pushed is correct. The author should have the same e-mail address that you’ve configured for your Gerrit account. If the author information is incorrect set the Git configuration parameters user.name and user.email to the correct values (you might want to set this globally by including the option --global):
$ git config user.name "John Doe" $ $ git config user.email email@example.com $
Now you should update the author for those commits where the author information is wrong. If only the last commit is affected you can do this by amending the last commit and explicitly setting the author:
$ git commit --amend --author "John Doe <firstname.lastname@example.org>"
If you need to update the author information for several commits it gets more complicated. In this case you have to do an interactive git rebase for the affected commits. While doing the interactive rebase you have to choose edit for those commits for which the author should be rewritten. When the rebase stops at such a commit you have to amend the commit, explicitly setting the author before continuing the rebase.
Here is an example that shows how the interactive rebase is used to update the author for the last 3 commits:
$ git rebase -i HEAD~3 edit 51f0d47 one commit edit 7299690 another commit edit 304ad96 one more commit Stopped at 51f0d47... one commit You can amend the commit now, with git commit --amend Once you are satisfied with your changes, run git rebase --continue $ git commit --amend --author "John Doe <email@example.com>" [detached HEAD baea1e4] one commit Author: John Doe <firstname.lastname@example.org> 1 files changed, 4 insertions(+), 1 deletions(-) $ git rebase --continue ...
For further details about git rebase please check the Git documentation.
If pushing to Gerrit fails with the error message “invalid author” and somebody else is author of the commit for which the push fails, then you have no permissions to forge the author identity. In this case you may contact the project owner to request the access right +1 Forge Author Identity in the Forge Identity category or ask the maintainer to commit this change on the author’s behalf.
