Subject: 24.3.50; DocView problem with cached files
Date: Tue, 13 Nov 2012 12:12:42 +0100

When I revisit a PDF file that DocView has cached (also when starting
with -Q, with the cache /tmp/docview1000), trying to scroll past the
bottom or top of the page fails with the error
"doc-view-scroll-up-or-next-page: Wrong type argument:
number-or-marker-p, nil" or "doc-view-scroll-down-or-previous-page:
Wrong type argument: number-or-marker-p, nil" and in either case also
with "Error during redisplay: (eval (number-to-string
(doc-view-current-page))) signaled (wrong-type-argument numberp nil)".
In addition, the page number indication in the mode line looks odd:
e.g. for a one page document it shows "P/1", for a five page document it
shows "P/5" (only the first page is displayed).

This problem vanishes if I type `C-c C-c' to view the PDF source and
then type it again to redisplay the image: now scrolling works and the
mode line displays "P1/1" or "P1/5".  If I kill the buffer and revisit
the cached file, the problem reoccurs.  Instead of `C-c C-c', typing `W'
or `H' also redisplays the image, and now scrolling works but the size
is unaltered; repeating `W' or `H' correctly displays the changed size.
Finally, if I delete the cache and then revisit the file, there is no
problem (but there is as soon as I revisit a cached file).

The problem does not seem to happen with large PDF that have many pages;
maybe these are not cached.  It also does not happen with PS files, but
those are initially visited in ps-mode and I have to type `C-c C-c' to
view the image, so this may circumvent the problem I see with PDF files
(I currently cannot view ODF or DOCX files with DocView).

I think this problem started some time between trunk revisions 110689
and 110748 (it happened with my build from the latter but not with my
build from the former revision); I haven't had time to bisect.  It also
happens with the emacs-24 branch, revno 110854; it does not happen with
the openSUSE build of 24.2 from 2012-10-10.

I can confirm the issue.  The problem is that (doc-view-current-page)
and returns nil, although that's setf-ed in `doc-view-initiate-display'.
But I think at this time, the window going to hold the images isn't
there already.

As a workaround, do `M-g M-g 1 RET'.  I'll look into this issue later
today.

Hi Stephen & Stefan,

the following patch fixes the issue for me, but I'm not sure if it's the
right thing to do.  Stefan, could you please check?

Basically, the difference between finding a not yet converted doc and a
doc that's already cached is that in the former case
`doc-view-goto-page' runs with the selected window displaying the doc's
buffer.  AFAIKS, that's a must for the image-mode winprops stuff to
work, so in the latter case, the patch defers running
`doc-view-goto-page' a bit into the future when the window showing the
doc buffer is hopefully there.

The patch fixes the problem for me, too; thanks.  However, the delay of
0.1 seconds results in the unconverted file being noticeable before the
image is displayed.  I tried it with a 0.01 second delay and this makes
the image appear practically instantly to me, i.e., I didn't see the
unconverted source, and the paging still worked.  I don't know if this
short a delay is always guaranteed to succeed.

Yes, but that's no big deal IMHO.  You'll see the raw source for a short
time also when the doc isn't cached already.

It'll also work, but chances increase that the page-setting is deferred
another fraction again.  I tried to set the value so that it's not
inconvenient but at the same time shouldn't need to delay again on
slower systems.

How about making it customizable?

Surely that could be done.  But I have no idea about a good description
not involving technical details that users shouldn't have to care about.
So maybe using a shorter delay is ok.  After all, using doc-view is
computational intensive anyhow (at least the conversion with gs and
friends)...

Anyway, before going any further, I'd like to wait for Stefan telling us
if that's the right approach altogether.

[ BTW, using a "diff -b" is very helpful for such patches which
  reindent a lot of code. ]

Actually, no, the winprops stuff should also work when the buffer is not
displayed anywhere.

But I can't seem to reproduce the OP's problem.
I tried just "emacs -Q ~/tmp/foo.pdf; emacs -Q ~/tmp/foo.pdf" and it
worked fine.

I have the strange impression that the problem was actually not in
doc-view.el or image-mode.el (neither of which was modified between 110689
and 110748).  I instead suspect it was a temporary bug in gv.el.
It's been fixed since, but the fix will only become effective after
recompiling the victim.

IOW, can you recompile image-mode.el and doc-view.el (or do a full
bootstrap) and then tell us whether you still see the problem (and if
so, try to provide a more detailed recipe)?

Right, I'll do the next time.

Not here running "eliz <at> gnu.org-20121114172255-6mbtm95gmreikpt1", that is
revno 110896.  I have the same symptoms as Stephen, that is, "P/17" in
mode-line and `doc-view-next-page' and friends error.

There are some newer commits since then, but none in
lisp/emacs-lisp/gv.el.

I run Gentoo GNU/Linux, so everytime I reinstall the emacs-vcs package,
it'll do a complete vanialla install bootstrapping and recompiling
everything.

I'll update to revno 110904 to see if it works and report back.

Done so, and the problem still exists.

The original bug report was a bit vague about what the bug was, but I
tried reproducing it with


$ emacs -Q ~/tmp/foo.pdf
C-x C-c
$ emacs -Q ~/tmp/foo.pdf
<down>

and I'm not able to get Emacs to bug out.  So is anybody seeing this
problem still?  If so, what are the steps to reproduce it?

With emacs 27 and master I can't reproduce the problems I originally
reported either.

Thanks for checking.  I guess this has been fixed then, so I'm closing
thing bug report.
