WW 2.16 RC1 minor issue - console errors when rendering in library browser

[taniwallach]

When I load problems in the library browser on WW 2.16RC1, I see JS console error messages about

• math4-overrides.css
• math4-overrides.js
• math4-coloring.css
  as at least by me these files do not seem to exist. (Error messages below.)

I assume that the same sort of issue would occur when a problem was loaded via html2xml in some other context using one of the formats that expects these files to exist.

It seems that a reasonable fix is to

cd /opt/webwork/webwork2/htdocs/themes/math4 ; /usr/bin/touch math4-overrides.css math4-overrides.js math4-coloring.css

inside docker-entrypount.sh. So far I only tested manually doing this inside the container.

Note: The math4-coloring.css file exists only in htdocs/themes/math4-red and htdocs/themes/math4-green but not in the plain htdocs/themes/math4.

These console warnings can be ignored. This was stated when this was implemented. There is no harm in a file not being found. If you want to make the warnings go away you could do what you suggest in your system.

I guess I didn't state it in the pull request, but mentioned it in our weekly meeting.

No real harm, but when debugging other problems - the excess console warning messages are distracting. The web request and a reply occur anyway, so why not set things up (Docker and install instructions) so that an empty file gets served instead of triggering a 404?

[drgrice1]

As I said, you can always set it up that way on your server. Feel free to add it to the docker build and install instructions.

Being fixed for Docker as part of #1404.

This is fixed in #1599. These files are now created if not present when the htdocs/generate-assets.js script is run.
