I forgot to switch my working copy back to the correct branch and made some changes.
How can I commit the current changes (but not all other changes in the current branch) to my original branch?
If I understand correctly, you have uncommitted changes that need to be on top of another branch.
My prefered way is to use the shelf functionality to save all your changes, update to the correct branch, and then un-shelf your changes back on the proper branch.
To do it on the command line, save the result of hg diff in a patch file, then update to the other branch and hg import <patch>.
Finally, just commit your changeset, as you wanted.
Shelve extension allow you to store WIP, get clean working dir, update to needed branch, release shelve
MQ exension (somehow overkill) allow to do the same thing, as shelve
At last, you can commit into wrong branch and rebase this changeset to the correct parent, using Rebase extension

I have two branches let's say A and B. I have done few changes in A and committed my code into A then i have merged A into B and did a push.
Now the problem is i have added some unnecessary files into B.
I want o revert to a prev version of B. I have see few solutions to perform hg update -r and then forcefully push it to the repo which might lead to new heads which i don't want to do.
Bare me for the explanation, doing this for the first time. Thanks.
I want to revert back to 3313 revision
you can go on your head, remove the unnecessary files, commit and push.
Go to your branch B
hg update -r 3316
Remove the files, commit and push
hg forget yourfilethere
hg commit -m "Remove unecessary files"
hg push
let me know if it helps!
If what you want is to remove or modify a pushed revision, then I am afraid Mercurial (by design) does not support this. (You can change the phase of a revision to 'draft' and strip or amend it, but when you pull again the old revision will re-appear.)
If you really need to remove the revision (e.g. it contains some huge files), then there is nothing you can do about it on your local repository; the only way this can be done is on the remote repository (e.g. having the administrator run hg strip directly on the remote repository, or some equivalent thereof; the BitBucket interface does support stripping a revision).
We have had a similar problem at work, where some user committed very large files to the repository, and a lot of work was done on the repository afterwards. The only way we were to solve it was using the 'convert' extension to remove the files, and then pushing into a brand new repository. (If we had just pushed the converted repository to the existing one, this would just have created duplicate revisions starting from the point where the bad files were committed.)
Is there a way to disassociate a file on a feature branch from its parent branch, in that changes to the file on the parent branch will no longer merge into the feature branch?
ie: app/index.html [develop] changes should no longer merge into app/index.html [feature/redesign] when merging develop into feature/redesign ?
You should ask yourself why you want to do this, it sounds backwards. Anyway, the following should work: perform the merge as usual, don't care about what happens to app/index.html (that is, in case of conflict just accept something, don't think about it). Then, before doing the merge commit, revert that file to its previous revision on redesign branch. To make an example:
(on branch redesign)
hg merge develop
hg revert -r redesign app/index.html
Now hg status will still show app/index.html as modified, but if you look at its contents, they are the same as before the merge. Do the merge commit as usual:
hg commit -m 'Merge develop into redesign'
Note: you must do this each time you do a merge, there is no "dissociate" capability.
Just delete and re-create it on the branch.
I am currently using Mercurial for sub-version control in my project. Now I am suppose to work on a new branch 2.7 but I confuse to work with branch 2.6, I have developed the new feature which the feature on 2.7 but I build on 2.6. And now I want to move this feature to branch 2.7 properly but I don't know how can I move it properly. Is there any way?
I would recommend using hg graft, which copies changes from one branch to another and unlike hg rebase is not destructive (relevant if you're doing this for the first time and may be making mistakes or if you need the feature to be present on both branches).
To copy changes to a branch dest-branch, do the following. First update to the branch you want to copy the changes to:
hg update dest-branch
Then, use graft to copy the revisions you want from the original branch, e.g.:
hg graft -r start..end
where start is the first revision you want to graft from the source branch and end is the last revision.
You may encounter conflicts if they can't be merged cleanly, which you have to resolve them (as you'd do in a merge), then use hg graft --continue to graft the remaining revisions.
The magic word is RTFM - hg help rebase
I was working in branch-a when I found an unrelated bug that should be fixed in the default branch. So, I'd like commit some of my changes to default, then merge default into the current branch, and keep working.
As far as I know, Mercurial doesn't allow committing directly into another branch, so I would have to switch to the default branch first. The problem is, I can't simply checkout the default branch, because the other changes would cause conflicts. One workflow I can think of is to shelve, checkout default, unshelve only the files that relate to the fix, commit, checkout branch-a, merge default, and finally, unshelve the rest of the files. Is there an easier way to accomplish this?
Commit only subset of files, related to branch-a changes (use additionally power of Record Extension, if bugfix's and branch-a's changes happens in some file(s) - commit only needed hunks of file) as changeset A
If you haven't MQ Extension:
Commit the rest of changes into branch-a as changeset B (child of A)
Rebase B (with Rebase Extension) changeset into default branch with --keep option in oder to have B in original location also
If you have MQ extension
Create new patch with working-dir changes
Unapply MQ-patch
Update to default
Apply patch
Test, test...
Finish patch (convert to permanent changeset)
Graft this changeset only into branch-a branch
My use case is this:
I am working on a new feature and I have several commits on that feature.
Since it was a minor feature, I didn't even consider doing the feature in a feature branch.
However. Now my boss comes along and tells me to fix a bug on the same branch that I am working on (default).
To fix that I'd like to create a feature branch for my feature, push all my existing (unpushed) commits into that branch.
So I'd like to create a branch just before my first commit and then somehow move all my commits to that branch.
How can I do this?
There’s two ways to approach this, depending on your preference:
In a new repository.
Make a new clone of your repository, and do the bug fix you need to make there. Then push it to the main repository when you’re done, and continue where you left off in the original repository. Pull and merge to get the new changes as usual.
In the existing repository.
Update to the changeset before your local changes, and just start fixing and committing there. This creates a new anonymous branch. When you’re done, push using push -r ., this will only push the changes that are included in the working copy. After this, merge with your original branch (hg merge) and continue where you left off.
Note that you can bookmark the feature branch with hg bookmark if you do not feel comfortable with leaving your changes unlabeled. Also you can easily find back any heads you left behind using hg heads.
Personally I prefer to work in a new clean clone, as you don’t need to worry about branching and where to leave uncommitted changes. However if your project setup is complicated it may be more convenient to reuse the existing repo.
For this situation you can fix it by rebasing (which may need enabling in your configuration).
On your branch, update to the revision before the change-sets you want to move:
hg up -r<revison>
This assumes contiguous revisions need moving.
Create a new branch:
hg branch "TempWork"
Put a dummy commit onto it in order to get a new revision:
hg commit -m"New Branch"
Then perform the rebase from the first of the change-sets you want to move (it moves descendants automatically) and specify the new branch revision as the destination:
hg rebase -s<base revision> -d<new branch revision>
Then update back onto your main-line branch.
Fourth method: Using mq-patches
You have to have mq extension enabled and initiated for repo
On hotfix moment you
convert feature-commits into set of mq-patches (hg qimport)
Unapply all patches in set (hg qpop -a)
Code hotfix, commit
...
Finish and test hotfix on clean codebase
Apply all patches in set (hg qpush -a), fix possible conflicts
Convert patches back to changeset (hg qfinish)
