Subject: 12.1.2; TeX-evince-sync-view locking up with this file
Date: Fri, 29 Mar 2019 02:32:50 +0530 (IST)

Hi,

I managed to get `TeX-evince-sync-view` to consistently lock up with
this file. I realise this is a pathological case, but I still think
that it could be handled better.

I wrote a question on TeX Stack Exchange, which is currently at
https://tex.stackexchange.com/q/481892/3406

I'll mostly just reproduce that question below. The file also appears
below.

When I compile this file with AUCTeX, it shows that one page has been
compiled. When I try to view it, using `TeX-evince-sync-view`, it
shows a blank view. After I kill it, `TeX-evince-sync-view` stops
responding, and gives me a D-Bus error: "call timed out" message. I
suppose this is because the only LaTeX file here is in a different
file, and the main file doesn't have any content, but AUCTeX really
should cope better. Can anyone reproduce this?

Suggestions how to unstop D-Bus in this sort of situation (just for my
reference) would also be helpful.

Regards, Faheem Mitha

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I don't use evince, and I'm not on Debian, but they way I see it running
pdflatex on this file (called mwe.ltx):

--8<---------------cut here---------------start------------->8---
\documentclass[12pt]{article}

\usepackage{shellesc}
\usepackage{tikz}
\usepackage{pdfpages}

\begin{document}

\begin{filecontents*}[overwrite]{mwe-bar.tex}
\documentclass[12pt]{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}  % This will be output to bar
\node [font=\bfseries\Large, align=center] at (7, 4.1){TEST};
\end{tikzpicture}
\end{document}
\end{filecontents*}

\ShellEscape{pdflatex mwe-bar.tex}

\end{document}

%%% Local Variables:
%%% mode: LaTeX
%%% TeX-master: t
%%% TeX-source-correlate-mode: t
%%% TeX-command-extra-options: "--shell-escape"
%%% End:
--8<---------------cut here---------------end--------------->8---

produces this log file:

--8<---------------cut here---------------start------------->8---
...
Output written on mwe-bar.pdf (1 page, 17553 bytes).
Transcript written on mwe-bar.log.
(./mwe.aux) )
No pages of output.
Transcript written on mwe.log.
--8<---------------cut here---------------end--------------->8---

which says that 1 page is produced for the code written by filecontents*
environment, but the main document didn't produce any pages.  My viewer
(skim) says that there is no mwe.pdf to open, and ends gracefully.

I'm not sure why AUCTeX should do this better?  At the end of the day,
it just hands over a shell command and tells the viewer which file to
open.  I haven't checked the code for `TeX-view', but I don't see the
issue on AUCTeX's side per se.

Can you still produce this issue if you update your setup?

No response.  I'm closing this report for now.  We can reopen if new
input arrives.
