abort: added support for graft

Authored by taapas1128 on Jun 23 2019, 1:43 PM.



This adds support of graft to hg abort plan.

The patch creates a seperate function cmdutil.hgabortgraft
so that abort logic for graft can be called independently.
This logic is registered to the statedetection API as abortfunc.

Results are shown as tests.

I think we can use cases functionality in existing tests to test hg abort.

I mean, in one case alias abort to graft --abort and in other case it will be the normal abort command. That will help us to prevent duplicating tests and making sure in future things work for both the cases.

Directly calling _abortgraft is not safe. graft --abort takes wlock first and then calls it. We skipped taking the lock in case of hg abort.

@pulkit the wlock is activated later in graft --abort during cleanup. That is same in the case of hg abort


I will alias this later if you want once the code for this is finalized. this is only a portion of tests taken and tests for no-backup and dry-run are added.

_dograft() is called after taking the lock. _abortgraft before taking the lock does a lot of reading which should be covered with lock. Otherwise there can be a process which changes state of things between we read the data and we operate on it.


Let's start aliasing from now and have current set of patches good to go.

Tests have been shown as test-abort.t

There is no such test now. :)


let's move this function to cmdutil.py. Should move _readgraftstate, _abortgraftstate to cmdutil.py too. Movement can be done as a separate patch before this patch.


aborting graft ...


We can get rid of this if if we prevent calling abortfunc() in abort command.

graft currently supports --dry-run flag.

This sounds ambiguous. Does this means hg graft supports --dry-run flag? IIUC, hg abort supports --dry-run flag which is mentioned in last patch and we can drop the mention here. Applies to next patches too which has similar mention in commit messages.
