bug#30235: [patch] undo-tree byte-compiler warnings

[Alex Branham]

[-- Attachment #1: Type: text/plain, Size: 8294 bytes --]

I'm not sure if this is the right place to submit patches for ELPA
packages, but I couldn't find anywhere else to go. Let me know if this
should go some place else.

This patch silences several byte compiler warnings, mostly having to do
with unused lexical variables in loops. There are two remaining that I
couldn't figure out how to deal with because I'm not terribly familiar
with the innards of Emacs's undo feature. (Note that the line numbers
are after applying the attached patch):

In undo-tree-pull-undo-in-region-branch:
undo-tree.el:2261:16:Warning: ‘undo-elt-crosses-region’ is an obsolete
    function (as of 25.1).

In undo-tree-pull-redo-in-region-branch:
undo-tree.el:2470:16:Warning: ‘undo-elt-crosses-region’ is an obsolete
    function (as of 25.1).

The unused dolist fixes look OK, but they could also be rewritten as

(cl-loop repeat ...
         do ...)

to avoid the binding altogether.

The other changes (time-subtract/subtract-time) I'm not so sure about,
because ELPA things are supposed to work across a large number of Emacs
versions, and time-subtract is newer than subtract-time.

The same with the other obsolete functions -- you're bound to get those
warnings in ELPA packages.

There's really no need to completely rewrite all those dotimes in terms
of cl-loop.  Writing (dotimes (_ ...) ...) is quite common and fine.

Sure, but subtract-time has been called time-subtract for almost two
decades now[1].

Sure, but often a compatibility shim can go a long way, and in this case
the question is why was undo-elt-crosses-region obsoleted as part of
bug#17235, and what should undo-tree.el do in future Emacs versions.

Maybe Barry, Toby, or Stefan should be CCed in this or a new discussion
about it, seeing as Jonas' concerns were never addressed, AFAICT.

Thanks,

That sounds safe, then.  :-)

Sure; go ahead and poke them about it.

Warnings are meant to be our helpers, not our masters.
We should not get in the habit of jumping through hoops
to satisfy a demanding, rigid program.

While my preference is to avoid compiler warnings (because having a
warning-free build allows anybody working on the code to proceed with
greater speed and confidence), I think that for ELPA code this should be
up to the maintainer.  Since it seems like Toby is opposed to these
changes, I'm closing this bug report.

bug#30235: [patch] undo-tree byte-compiler warnings

[Toby Cubitt]

Hi Alex,

Not opposed to this at all! (I forgot what i said previously, but if I was then it was before I knew of the _ method.) Indeed, I think I already made exactly this change a while back in the undo-tree development repo, but maybe forgot to transfer this into ELPA.

Undo-tree went into ELPA before there was support for separate per-package git repos in ELPA, which is why this isn't automatic. It makes upstreaming changes from my development repo(s) to ELPA that bit more complicated than a simple git push. I'm very busy with real life these days, so this inevitably gets forgotten/postponed. Maybe this is a good opportunity to shift all my ELPA packages over to per-package git repos, so I can just make the ELPA repos upstreams of my package development repos?

Best wishes,
Toby

Oh, OK.  :-)

Sounds like a good idea.
