Update the documentation to clarify that it is necessary to replace the Change-Id when re-pushing a commit to the same destination branch. Previously the documentation also implied that this was necessary when pushing to a different branch. Bug: Issue 8222 Change-Id: I4a7f87322c7117f34d2ea3a8be8eec4b38fa406a

= no new changes
|
|
|
|
With this error message Gerrit rejects to push a commit if the pushed
|
|
commit was already successfully pushed to Gerrit in project scope.
|
|
In this case there is no new change and consequently there is nothing
|
|
for Gerrit to do.
|
|
|
|
If your push is failing with this error message, you normally
|
|
don't have to do anything since the commit was already successfully
|
|
pushed. Still this error message may sometimes come as a surprise if
|
|
you expected a new commit to be pushed. In this case you should
|
|
verify that:
|
|
|
|
. your changes were successfully committed locally (otherwise there
|
|
is no new commit which can be pushed)
|
|
. you are pushing the correct commit (e.g. if you are pushing HEAD
|
|
make sure you have locally checked out the correct branch)
|
|
|
|
If you are sure you are pushing the correct commit and you are still
|
|
getting the "no new changes" error unexpectedly you can take the
|
|
commit ID and search for the corresponding change in Gerrit. To do
|
|
this simply paste the commit ID in the Gerrit Web UI into the search
|
|
field. Details about how to search in Gerrit are explained link:user-search.html[here].
|
|
|
|
Please note that each commit can really be pushed only once. This
|
|
means:
|
|
|
|
. you cannot push a commit again even if the change for which the
|
|
commit was pushed before was abandoned (but you may restore the
|
|
abandoned change)
|
|
. you cannot reset a change to an old patch set by pushing the old
|
|
commit for this change again
|
|
. if a commit was pushed to one branch you cannot push this commit
|
|
to another branch in project scope.
|
|
. if a commit was pushed directly to a branch (without going through
|
|
code review) you cannot push this commit once again for code
|
|
review (please note that in this case searching by the commit ID
|
|
in the Gerrit Web UI will not find any change)
|
|
|
|
If you need to re-push a commit you may rewrite this commit by
|
|
link:http://www.kernel.org/pub/software/scm/git/docs/git-commit.html[amending] it or doing an interactive link:http://www.kernel.org/pub/software/scm/git/docs/git-rebase.html[git rebase]. By rewriting the
|
|
commit you actually create a new commit (with a new commit ID in
|
|
project scope) which can then be pushed to Gerrit.
|
|
|
|
If you are pushing the new change to the same destination branch as
|
|
the old commit (case 1 above), you also need to replace it with a new
|
|
Change-Id, otherwise the push will fail with another error message.
|
|
|
|
== Fast-forward merges
|
|
|
|
You will also encounter this error if you did a Fast-forward merge
|
|
and try to push the result. A workaround is to use the
|
|
link:user-upload.html#base[Selecting Merge Base]
|
|
feature or enable the
|
|
link:project-configuration.html#_use_target_branch_when_determining_new_changes_to_open[
|
|
Use target branch when determining new changes to open]
|
|
configuration.
