Large SVG files fail to render in Thumbor (due to lack of use of the --unlimited option in librsvg)
Closed, ResolvedPublic


Details of the error are attached to the report, which will be publicly viewable. If you are not comfortable with that, you can edit the report below and remove all the data you don't want to share.

Yet again, one of my files is not showing in Media Viewer or thumbnails, but the direct file works. I was previously told that it might be the thumbnails and pngs still generating, and my other files' problems solved themselves after a few minutes or hours, but this file has had problems since it was uploaded 2 days ago.

Thanks for reporting this! Indeed, triggers a "HTTP 500 Internal Server Error".

(Unrelated: also has font size issues when displaying in Firefox on Linux.
Inkscape on Linux says FontLister::get_best_style_match(): can't find family: Sans here.)

"can't find family: Sans"
That's interesting. In Inkscape, which I use to make my maps, "Sans" is the default text font. However, a warning icon shows next to it (to indicate that it doesn't exist on my computer). The text essentially shows as Arial in Inkscape, but after uploading to Wikimedia Commons, it shows as some Times New Roman-looking font for me. I try to switch all my text to Arial before I upload, but some Sans must have crept in there.

Same issue as T170109 (ie. blocked on T150734/T169683).

Not the same issue. In this case it's an error coming from rsvg-convert:

error: `(['/usr/bin/rsvg-convert', '/srv/thumbor/tmp/thumbor@8811/tmpYms0rR', '-f', 'png', '-w', '603'], '', 'Error reading SVG:Error domain 1 code 1 on line 1 column 1 of file:///srv/thumbor/tmp/thumbor@8811/tmpYms0rR: internal error: Huge input lookup\n\n\n', 1)`

It seems to be explained in T111815: SVG files larger than 10 MB cannot be thumbnailed and should be resolved by the use of the --unlimited option
