[bug] line move and truncation

[bug] line move and truncation

[Lars Hansen]

With Emacs of today, do
   emacs --no-site-file --no-init-file --eval=(setq-default 
truncate-lines t)
Open a file with long lines. (You may open files.el and search for 
read-directory-names).
With point on a truncated line, hit down-arrow (or C-n if you prefer that).
Then point will move down two lines (as if lines were wrapped rather 
than truncated).
Nothing seems to be wrong when you move upwards.

It's caused by a recent change to Fvertical_motion.

I just posted an analysis of the problem to emacs-pretest-bug ...

Thanks.
BTW, who is monitoring emacs-pretest-bug?

Well, I found out why Richard made the change.

I have installed a fix for the new problem.

This is a serious problem.  It seems many Emacs developers are not
subscribed to emacs-pretest-bug.  That might explain why some bugs
remain unfixed.  Also often bug reports results in discussions that
should belong to emacs-devel, and where unsubscribed Emacs developers
can't participate.  And often developers report bugs on emacs-devel,
(perhaps anticipating a possible discussion).  So really emacs-pretest-bug
looks like a part of emacs-devel "hidden" from many Emacs developers.
This hampers the development.  A good solution is to declare
emacs-pretest-bug obsolete and to change the value of
`report-emacs-bug-pretest-address' to "emacs-devel@gnu.org".

And what prevents you from subscribing to emacs-pretest-bug?  It's a
public list, AFAIK.

No.  emacs-devel is for _discussions_about_ Emacs development, while
emacs-pretest-bug is for reporting bugs and related discussions, and
only for that.  Therefore, people who read emacs-pretest-bug should be
those who are interested in working on fixing bugs, not simply have
some interest in Emacs development.

The fact that some people report bugs on emacs-devel IMHO means
nothing except that those people wrote to the wrong address.  But
since all those who subscribe to emacs-pretest-bug also read
emacs-devel, we don't usually tell such people to take the thread to
emacs-pretest-bug.

This seems like a rather bizarre justification.... surely the _vast_ majority
of people who read emacs-devel are interested in fixing bugs.

As far as I can see, emacs-pretest-bug is already effectively obsoleted by
emacs-devel, but still gets a few random postings because of the way emacs is
configured, and out of habit by a few long-term hackers and pretesters.

It would be much less confusing to just redirect emacs-pretest-bug to
emacs-devel and be done with it.

What's bizarre about it?

Any statistics on that?  Like, e.g., a comparison of the list of
subscribers to emacs-devel against the list of people whose names
appear in ChangeLog files?

Re: emacs-pretest-bug (Was: [bug] line move and truncation)

[Richard Stallman]

I read emacs-pretest-bug, and when I see an extended discussion
happening there, I often move the discussion to emacs-devel.

That said, the distinction between the lists may not be useful just
now.  The general idea is that emacs-pretest-bug is for fixing bugs,
while emacs-devel is more general, and includes discussion of new
features.  However, at present we don't want to discuss new features,
so at present the lists are duplicates.

So perhaps it would be better to direct bug reports to emacs-devel for
the time being.
