rHGd7a508a75d72: strip: move into core
rHGa46efd42ae70: strip: move into core
Summary

As discussed at the 5.2 sprint, replace strip extension by a core
command, debugstrip. Obviously, the extension stays for backwards
compatibility.

As an implementation note, I moved the strip file as is into core,
which is not done elsewhere, AFAIK. I could have inlined it into
debugcommands, but that doesn't sound great.

My memory from the discussion was that we explicitly wanted to keep it as extension as it normal users shouldn't use this and it is considered dangerous?

valentin.gatienbaron added a comment.Nov 8 2020, 7:16 PM

Was that the conclusion? I think I was taking notes and missed it. I thought turning the strip extension into a debugstrip command was already agreed upon a year ago, In fact, D6987 was started back then (and stalled, but that's unrelated).
There's no disagreement that the command is dangerous, that's why it's debugstrip and not strip. That seems like better pushback to me than an extension.

This fails test-check-format.t for me. I'll fix it in flight.

valentin.gatienbaron added a comment.Nov 25 2020, 12:52 AM

Oops, sorry, I didn't have black installed, so test-check-format.t was getting skipped. Having installed it now (at version 19.10, because 20.8b is broken), there are indeed formatting issues. Thanks for the fix.

"""strip changesets and all their descendants from the repository
The strip command removes the specified changesets and all their
descendants. If the working directory has uncommitted changes, the
operation is aborted unless the --force flag is supplied, in which
case changes will be discarded.
If a parent of the working directory is stripped, then the working
directory will automatically be updated to the most recent
available ancestor of the stripped parent after the operation
completes.
Any stripped changesets are stored in ``.hg/strip-backup`` as a
bundle (see :hg:`help bundle` and :hg:`help unbundle`). They can
be restored by running :hg:`unbundle .hg/strip-backup/BUNDLE`,
where BUNDLE is the bundle file created by the strip. Note that
the local revision numbers will in general be different after the
restore.
Use the --no-backup option to discard the backup bundle once the
operation completes.
Strip is not a history-rewriting operation and can be used on
changesets in the public phase. But if the stripped changesets have
been pushed to a remote repository you will likely pull them again.
