hanging on missing picture

hanging on missing picture

[Hans van der Meer]

Requesting a non-existing picture does not produce a warning message, but makes ConTeXt hang. An abort is the only thing that helps. It would however be nice if a "missing file" warning is given. A minimal example that shows me the hang:

\starttext
Hello a picture?\par
\externalfigure[./Figuren/figure.xxx]
\stoptext

That is not supposed to happen, I think. Normally, you would get a gray box in thr pdf to indicate that the figure was not found.

Hi,

On my installation of ConTeXt, there is no hanging: maybe there is an issue with your intsllation?
The output shows a grey rectangle with 
	name : dummy
	file: figure
	state: unknown
written on it.

For your information, I tested your code on a Mac OS X 10.6.6 and the minimals (version 2011.02.25).

Best regards: OK

I'm not sure, but until yesterday ConTeXt kept hanging in most
unexpected moments for not-really-predictable reasons and maybe that
is just one of them.

Well, here it does hang. I also have MacOSX 10.6.6 but then I have the minimals  ver: 2011.02.05 11:37 MKIV  fmt: 2011.2.5.
The later version: ConTeXt  ver: 2011.02.25 22:03 MKIV  fmt: 2011.3.11 does work as advertised though.

Pity I have to use the older version until another incompatibility is solved: 
resolvers       > modules > loaded: 'bib'
(/Users/hans/context/tex/texmf-context/tex/context/base/m-obsolete.tex
! Undefined control sequence.
I hope to hear soon about that one.

I just commented out a single line in m-obsolete to make it work.

Re: hanging on missing picture

Hi,

I did the test with your code both with mkii and mkiv (version 2011.02.25, 22:03).  In mkii I get what I reported previously and in mkiv I get:
	name : dummy
	file: ./Figuren/figure.xxx
	state: unknown

I have noticed the hanging behaviour of mkiv in some other situations, but actually if I wait long enough mkiv comes back and the typesetting goes through… I had the impression of having a cache problem, since if I remove or rename the folder
	/context-minimal/tex/texmf-cache/luatex-cache
then mkiv gets lost, despite a new folder being created.

Maybe in your situation there is an analogous condition?

Best regards: OK

there should be a \normalexpanded in here:

\def\externalfigurereplacement#1#2#3%
   {\setupcolors
      [\c!state=\v!local]%
    \normalexpanded{\localframed
      [\??ef]
      [\c!width=\figurewidth,
       \c!height=\figureheight,
       \c!background=\v!color,
       \c!backgroundcolor=missingfigurecolor,
       \c!frame=\@@efframe]}% we need to expand this in order to prevent 
a loop
      {\tt\tfxx \nohyphens
         name:  \expanded{\verbatimstring{#1}}\\%
         file:  \expanded{\verbatimstring{#2}}\\%
         state: \expanded{\verbatimstring{#3}}}}
