because themotte is ~~webscale~~ async, there is some window of time
where code in the sanitize fn will cause the entire worker to crash and
not in a fun way. anyway this uses gevent to handle timeouts instead of
a signal based system which is non-portable and is very fragile,
especially if themotte adds more async functionality in (something that
would probably further improve the performance of the site)
essentially... we don't want the failure of one request taking down the
entire worker!
This change disables multimedia embedding:
- In comments and comments replies.
- In new submissions.
- In comment & submission preview
And it's all toggle-able via an envvar, except for the JS bits,
but I linked those to the github issue, so should be easy to find
in the future.
The way it works is:
- removes markdown image/video syntax,
eg. `` into ``
- changes link text into anchors, eg.
`https://example.org/someimage.jpg` into
`[https://example.org/someimage.jpg](https://example.org/someimage.jpg)`
- removes html img/video/audio tags, eg.
`<img href="https://example.org/someimage.jpg" />` into ``
- when embedding gifs via the giphy modal in "new submission", it will
insert only an anchor to the gif
- when attaching an image, it will upload the image, then add only an
anchor to the post/comment body
I tested this manually, but not sure if I got all the test cases. What I
checked was:
- create comment w/ image/video/audio media using markdown -> success
- create comment reply w/ image/video/audio media using markdown ->
success
- create comment w/ link to img/imgur/youtube/audio -> success
- create comment w/ attachment -> success
- create comment reply w/ attachment -> success
- create comment w/ img/video tag -> success
- create comment reply w/ image/video tag -> success
- create post submission w/ image/video/media using markdown -> success
- create post submission w/ link to img/imgur/youtube/audio -> success
- create post submission w/ attachment -> success
- create post submission w/ giphy gif -> success
Also, updated the formatting page.
