Memory exhausted when viewing HTML messages

Memory exhausted when viewing HTML messages

[Christoph Groth]

Hey,

I'm using Gnus 5.13 with Emacs 24.4.50.  When mm-text-html-renderer is set to its default value shr, I often get the messasge “Memory exhausted--use C-x s then exit and restart Emacs” when opening some HTML messages.  Is this issue known?  If not, any suggestions how to debug it?

As a workaround, I set mm-text-html-renderer to gnus-w3m.

I haven't heard it mentioned before.

I guess an example of an email where this happens would help debugging
it - if you have one without any sensitive information that you can
share?

For getting a clue about what happens, maybe M-x toggle-debug-on-quit
and then hitting C-g while Emacs is working on exhausting memory might
give an interesting trace?


  Best regards,

I tried and couldn’t reproduce the problem using “emacs -q”, so 
lacking
other tools I turned to bisecting my ~/.emacs.  It turned out that 
the
problem is triggered by me setting fill-column to 
most-positive-fixnum
in gnus-article-mode-hook.

“shr” seems to allocate buffers that are proportional to 
fill-column.

I set fill-column to infinity in a function that also enables
visual-line-mode, adaptive-wrap-prefix-mode and 
variable-pitch-mode.
This allows to use “W w” (gnus-article-fill-cited-article) to wash 
away
hard line breaks from an article so that the text reflows 
nicely. (I
happen to like this – consider how œ and æ look with a fixed-width
font.)
