visibility: improve the message when accessing filtered obsolete rev
ClosedPublic

Authored by lothiraldan on Dec 5 2017, 9:11 AM.

Details

Summary

When trying to access filtered revision, it is likely because they have been
obsoleted by an obs-marker. The current message shows how to access the
revision anyway:

abort: hidden revision '13bedc178fce'!

But in the case of an obsoleted revision, the user is likely to want to update
to or use the successor of the revision.

We update the message to display more information about the obsolescence fate
of the revision in the following cases:

abort: hidden revision '13bedc178fce' is pruned!

abort: hidden revision '13bedc178fce' has diverged!

abort: hidden revision '13bedc178fce' was rewritten as X, Y and 2 more!

would it be better to put the verb in the abort top-line, isntead of the hint? that is:

abort: hidden revision 'a' is pruned!
(use --hidden to access hidden revisions)

or

abort: hidden revision 'a' is obsolete with successor: eb5a0daa2192
(use --hidden to access hidden revisions)

What do you think?

It's an interesting proposition, I don't have a strong opinion. The current behavior is the same as Evolve so it may be better to keep the same, but again no strong opinion.

After thinking more about your proposition, I also think that would be a nice improvement. This way we won't pollute the line helping people to access it anyway.

What I'm proposing:

abort: hidden revision '13bedc178fce' is pruned!
abort: hidden revision '13bedc178fce' has diverged!
abort: hidden revision '13bedc178fce' was rewritten as X, Y and 2 more!

The proposed phrase without divergence is closer to obsfate this way.

Works for me, make it so.

+1. I also like this way.

Apart from the comments, this patch looks good to me.

nit: I think in such cases we pass repo as first argument.

Also, I don't think this is a good place for this function, maybe move this to obsutil.py too.

We should follow the graph description here too i.e. saying split as x,y,z.

This one looks odd. Please make this one similar to other split message.

These should be 'superseded' and 'superseded_split' (in the docstring above as well as here)

This has new failures in test-obshistory.t and test-directaccess.t, can you rebase?

@krbullock Done

I pulled from somewhere (likely hg-commited) and get an obs-marker authored by you:

x  72ca90721675 (40698) visibility: improve the message when accessing filtered obsolete rev
|    rewritten(meta, date) as 65044dd2280c by Boris Feld <boris.feld@octobus.net> (Fri Jan 05 09:12:08 2018 +0100)
|    rewritten as f34ff7e24012 by Kevin Bullock <kbullock+mercurial@ringworld.org> (Thu Jan 04 21:01:44 2018 -0600)

But I didn't receive f34ff7e24012, do you know what happened? I'm trying to check if there is a bug involved somewhere. Maybe you stripped f34ff7e24012 with a version of Mercurial that doesn't strip related markers?

Not translatable.

Needs a table of

{'pruned': _("hidden revision '%s' is pruned"),
 ...,
}

Can you send a followup?

Maybe it's okay to pass a "filtered" repo to this function as
templatekw.showsuccessorssets() does.
