I am Sajid, I like to know Is it possible that I can go back to my previous patch in my commit. I can explain:
I commit something. On the way to delivery, i fixed and update things and pushed into gerrit with commit --amend. But what I am experiencing now my last patch is a faulty so I like to go back to previous patch. and I don't know how can i point to my previous patch. And I also like to know will it be the same procedure even If I go to any previous patch.
thanks in advance.
As this answer said, patchsets can not be reverted. so first you have to checkout one of the previous patchset. you can get the command from Gerrit review board at each patchset download panel. For example:
git fetch https://android.googlesource.com/kernel/tegra refs/changes/43/69243/2 && git checkout FETCH_HEAD
After checking it out amend it to generate new commit hash then pushed again as a new patchset.

There are two (remote)branches in our project: dev and master. dev diverged from master some time ago and was used for development. I have some patchsets which are pending on dev (pushed to refs/for/dev and have review comments etc), but now dev has been merged into master and the patchset needs to be submitted to master instead of dev.
I would like to move the patchset from dev to master now since dev is no longer being used.
When I try cherry-picking the change onto master I get an error:
Cherry Pick Conflict! Cherry Pick failed! (merge conflicts) Please
select "Continue" to continue with conflicts or select "cancel" to
close the dialog.
and if I continue anyway I get this error:
An error occurred Could not perform action: Cannot create new patch
set of change 562407 because it is abandoned
If I try moving the change to master (suggested here: Rebasing current patchset in Gerrit onto another branch) I get this error:
An error occurred Could not perform action: Destination master has a
different change with same change key
Ie63692606xxx5841xxxxca2687ebxxxaa8f84d2
How can I get the change with all the comments etc. onto the master branch now? If not, how do I create a new change on the master branch for the same patch set?
If I checkout the patch and try git push origin HEAD:refs/for/master, I still get an error.
I had another patchset with the same changeId on the master which I had abandoned earlier, which is why the move patchset didn't work. After I deleted the abandoned patchset, I was able to move the change to the master branch (with conflicts that I now need to resolve.).
I cannot find an option to delete a PR on BitBucket.
Am I overlooking something or it's really not possible?
You can decline a pull request which has the same result -- stopping / removing the PR.
As per the link jonrsharpe mentioned, to the right of the merge button there are 3 dots. Under that menu you should have a delete option if you have permission to delete.
This is available only for BitBucket Server, not on BitBucket.org.
In BitBucket.org there is no option to delete the PR.
For Bitbucket Cloud, there are no way to do this. One way of getting by is to have a 'dev/junk' branch, used for declined or useless pull requests.
Then just edit the existing request to go into this branch and merge.
Data is still there, in case you need it some day, or if it's sensitive info you can remove the whole branch. If its already declined before, well, nothing can be done then other than recreating that repo
See https://jira.atlassian.com/browse/BCLOUD-8089 for the update on this feature request and vote on it!
I wanted to delete a pull request of a branch that had already been merged and deleted. Even though I am an admin of my project, I cannot see any "delete" options. For me what worked was to recreate the deleted branch from the main branch and push it. E.g.
git checkout master
git checkout -b [deleted branch name]
git push -u origin [deleted branch name]
Then I opened Bitbucket and the branch showed up as "merged" and disappeared from the PRs list.
You cannot delete the PR in bitbucket.org .
Using Decline option will do exactly what you want - the PR won't be visible in the tab Pull requests (you need to sort PR by Decline to see it) but on tab Branches you will see that in column Pull request you have removed your problematic PR.
PS you cannot undo Decline of PR, so take care
Right now, I am committing the changes for a bug fix (ticket), and then do a
git push origin HEAD:refs/for/master
and then go through the code review on Gerrit. If a coworker proposed a totally different fix, is there a way to try this alternative fix somehow as the same Gerrit code review but as an "alternative way"?
I thought of using this way:
do a git log to look at the commit number exactly before the commit
git checkout that commit
git checkout -b ticket-1234-alternative to start another branch and try the alternative fix
So this method starts from how the project was when you make the fix, and then lets you do an alternative fix, as a separate branch. Is there a way that might not involve creating a different branch but using the same branch and possibly associate it with the same Gerrit code review?
If you want to try a different fix you can choose one of the following:
1) You can amend your original commit (git commit --amend) and push the new commit as the patchset2 to the same change. If you decide to go back to the original commit you'll need to push it again as a patchset3.
2) You can make a new commit based in the parent commit (as you have suggested) and push to a new change on Gerrit. When you decide which change will be used you just need to abandon the other one.
Suppose that I made some changes and did this:
git add -A
git commit -m "comment commit_1"
Now I made more changes and did this again:
git add -A
git commit -m "comment commit_2"
Now, I basically want to discard commit_2 and start modifying my project again at the point of commit_1.
How do I do this?
If you don't mind losing the revisions at all (as if they never happened at all), you can do:
git reset --hard HEAD~
If you want to keep the current history and get a new version on top of what you have where you get rid of the changes of the revision, you can do:
git checkout HEAD~
git reset --soft the-branch
git commit -m "Taking back changes from the last revision"
# And if you like the result of this:
git branch -f the-branch
git checkout the-branch
There you go.
Now, I basically want to discard commit_2 and start modifying my project again at the point of commit_1.
If you literally want to discard commit_2, then it may be that you can use
git reset --hard HEAD^
(Note that at the time I wrote this, another post incorrectly told you to use HEAD~2; that would discard both commits, which is not what was asked.)
There are caveats to using commands that remove commits from a branch.
The first is that you could lose the changes you made in affected commits. That may seem a strange warning - you asked how to discard the changes - but realizing that mistakes happen, it's cause to be careful with these commands. (Just to clarify - if you did something like this accidentally, the changes would not be immediately lost forever; the reflogs offer a little safety net.)
Other issues arise if your repo has remotes and you've pushed the commit(s) in question to any of the remotes. It doesn't sound like that's an issue here, but if it is then there is more you should consider before removing commits from a branch.
But if you've looked it over and determined that you really do just want to discard the commits, the above should work. Do note, HEAD^ is just one of the possible expressions that refers to the second-to-last commit. At the moment it may be the simplest thing to use, but it won't always refer to that particular commit. HEAD^ really means "the commit which is the parent of the currently-checked-out commit".
If you're on the master branch, then master^ would also work - and would not depend on what's currently checked out. Even that changes whenever the master branch moves; if for some reason you need an expression that would continue to refer to the particular commit, you could create a tag
git tag mytag master^
and then mytag would work; or you could look up the commit ID of the commit in question (though it won't be a user-friendly name)
But I digress...
This is different from - and more drastic than - merely loading the 2nd-to-last commit as the question title suggests. To simply update your working tree with the 2nd-to-last commit's state, you could
git checkout HEAD^
This moves the HEAD (i.e. changes what's checked out) and updates the index and work tree, but it still keeps the commit on master in case you need it again later. However, it also puts you in a state called "detached head", meaning that git isn't really expecting you to create new commits from here.
If you want to both keep the old commit around, and be in a state where you can add commits on top of commit_1, then you need to create a new branch. If you did the previous checkout command, you could then
git checkout -b mybranch
and new changes could be committed to the new branch while leaving the original commit_2 on master. Or, you could put a branch (or tag) on commit_2 and then move master back to commit_1.
git checkout master
git branch mybranch
git reset --hard HEAD^
That may seem like a confusing number of options; but really that's because each one serves a somewhat different purpose, and only someone involved in your project is likely to have all the context to decide which makes sense.
So tl;dr - it sounds like you might be looking for git reset, but just doing that alone is only suitable if you really intend to permanently discard the changes from commit_2. If you really would want to preserve them for future reference (But maybe just weren't sure if that's an option) then there are ways to do that, too.
If I have multiple patch set versions for one change in Gerrit, it seems like I can only submit the latest patch set version (because only that one has the necessary button). Is there an easy way to instead submit one of the old patch set versions of the same change, using only my web browser on that Gerrit instance?
I know that I can fetch the wanted version of the patch set from my git client and push it as yet another new patch set version on top, but I would like to avoid having identical patch set versions multiple times in the review and discussion around it.
No, sorry, this is not currently possible. The design assumes that the most recent patch set is the one developers will review and test, and as such older patch sets can not be submitted. They also can not be reviewed/verified. If you want to use an older version of a patch set, you must re-submit it to make it the most recent patch set. To avoid no new changes error do git commit --amend and git will create a new sha1, which will be happily accepted by Gerrit as a new patch set.
There is no proper way to do this using only Gerrit UI. Cherry-pick the specific "patch set" of the "change list" (e.g. if there are 15 patch sets in a Change List and want to revert back to patch set #8). Get the cherry-pick command from Gerrit UI for the required patch set.
Run that cherry-pick command, and use git commit --amend, then push your change. It will generate new patch set (for above example #16).
The only way I could do this was as follows (from the change refspec assuming you are in Gerrit revision "<change-no>/3" and want to go back to "<change-no>/1").
git review -d <change no>,1
git commit --amend # modify something in the commit message
git review # resubmit the changes, will submit to rev 1
