Hi,
Currently in Iceberg to merge a branch into another, we need to checkout the branch into which we want to merge and then do the merge.
Checking out a branch also updates the code in the image, which when needing to perform automatic releases on a branch can cause issues.
Is there already a way in Iceberg to switch to a branch (for example `release`) and then merge another branch (for example `master`) into it without updating any code in the image?
The use-case is that the user is on the `master` branch and needs to merge `master` into `release` without changing any code in the image.
I found LGitRepository>>#merge:, but it seems not to be used anywhere in the image.
Another way would be to implement something like the method below. This:
- calculates what changes need to be merged
- always takes what is on the left branch (in this case what is on master overrides what is on release)
- does not call loadChangesInWorkingCopy: to update the working copy as the code is already in the image
- refreshes the dirty packages in case there are changes between what is on the image and what is on disk
```
IceMerge>>#executeWithAcceptingLeftOnConflictAndWithoutImageUpdate
| commitToAdvance |
mergeCommit validateCanMerge.
self isAlreadyMerged ifTrue: [ ^ self ].
self calculateChanges.
self conflictsDo: [ :operation |
operation selectLeft.
].
commitToAdvance := self updateHead.
"Do not update the working copy"
"repository workingCopy loadChangesInWorkingCopy: self changesToWorkingCopyTree."
repository workingCopy refreshDirtyPackages.
^ commitToAdvance
```
Could something like the above solution work? Or are there other issues to take into account?
Cheers,
Andrei
