1121211 - qbackout without mq

Status: RESOLVED FIXED

Description

[Steve Fink [:sfink] [:s:]]

I've wanted qbackout's functionality but using real commits.

See also bug 1117632.

Add an "oops" command to do the same thing as qbackout with real commits

I suspect this will fail if you don't have mq on your system at all (it still imports it, even if it only uses it if you run |hg qbackout| instead of |hg oops|.) But you don't need to have mq enabled in your .hgrc, at least. I can fix the rest later.

Also, I don't like the name "oops". It's just that "backout", "rollback", and "undo" are all taken. Suggestions welcome.

And note that |hg oops --apply| probably ought to just say "please use |hg graft -f| instead". But I haven't used this enough to know whether that's always what you want.

I'd be okay with a flag that extends stock 'backout' to do these things.

More of a rubber stamp, but can't see anything major after a quick skim through.

Thanks for sorting this :-)

I probably would too, but that's actual work as compared to mutating qbackout. :-) Also, I'm not sure if people would be happy with the merge-based backouts or not. They make more sense in a number of ways, but they're also kind of annoying.

I, too, vote for extending `hg backout`. It might also be possible to change the default behavior on repositories that are known to be Firefox repositories. The firefoxtree does something similar - changing the defaults of `hg push` when operating on a Firefox repository.

But I'm not going to block progress. We can always implement something marginally better later.

We should be steering people towards `hg graft --force` for cherry-picking commits in history. https://mozilla-version-control-tools.readthedocs.org/en/latest/hgmozilla/common.html#revive-a-commit-that-was-backed-out

Please don't get too attached to this :)

Agreed. So I just pushed an additional change that removes the --apply option from |hg oops| and updates the documentation to point to |hg graft -f| instead.
