rHGbb135a784b70: abort: added logic for of hg abort
Summary

This is part of GSoC19 project `Implement abort and
continue commands`. This patch is part of the abort plan.

This adds the basic logic for hg abort. This command
aborts an multistep operation like graft, histedit, rebase,
merge and unshelve if they are in an unfinished state.

The first part of the logic is determining the unfinished
operation from the state detection API under statemod.
This API is extended to support hg abort by adding a method
to register the abort logic as a function (here abortfunc).

Once the unfinished operation is determined the registered
logic is used to abort the command. The benefit of this kind
of framework is that any new extension developed can support
hg abort by registering the command and logic under
statedetection API.

hg abort currently supports --dry-run/-n flag only.
It is used to dry run hg abort

Further patches sequentially add support for graft, rebase,
unshelve, histedit and merge.

Need to set the parent of this patch

taapas1128 added a comment.Jun 24 2019, 5:47 AM

@martinvonz I wanted this as a seperate stack for now so that the previous stack can be committed first. Do you want me to update its parents and add it to the previous stack?

return state.abortfunc(ui, repo, **opts) instead of storing and calling that later.

153

we should pass opts to abortfunc too. I can think of --no-backup as a flag which tells not to store a backup when aborting.

A nice addition will be --dry-run flag which tells which operation will be aborted. Also, maybe add a message saying aborting <command>.

mercurial/state.py
99–100

the new argument needs documentation.

109

since we will be using this argument outside of this class, let's not prepend _ to the name.

165

Arguments for abort can increase in future. Rather pass the opts directly to abort functions for now and make related functions look for flag which they need.

I agree it's not nice, but seems like a good tradeoff to start and have better code.

172

should be ui.status() instead of error.Abort()

Can you mark this command as experimental for now, we will be close to release soon. Marking this as experimental will help us take more time to smoothen things out.

This help should be 'do not save backup bundle' as similar to strip command.

need to prepend r'' in front of dry_run for py3 compat.

165

we should return here so that abortstate.abortfunc() is not called below in case of dry-run.

hg abort currently supports --dry-run/-n flag only.
It is used to dry run hg abort

We should specify what does dry run does i.e. it prints the operation which will be aborted if hg abort is run.

mercurial/commands.py
139

You need a space between operation and (EXPERIMENTAL)

153

%s is in progress but does not support 'hg abort'.

158

Now that we don't have backup flag, and --dry-run is tackled before calling abortfunc, we can prevent passing **opts.
