SECURITY: Remove event handlers from SVG files 2019-12-11 17:04:50 +02:00
Penar Musaraj 102909edb3 FEATURE: Add support for secure media (#7888)
This PR introduces a new secure media setting. When enabled, it prevent unathorized access to media uploads (files of type image, video and audio). When the `login_required` setting is enabled, then all media uploads will be protected from unauthorized (anonymous) access. When `login_required`is disabled, only media in private messages will be protected from unauthorized access. 

A few notes: 

- the `prevent_anons_from_downloading_files` setting no longer applies to audio and video uploads
- the `secure_media` setting can only be enabled if S3 uploads are already enabled and configured
- upload records have a new column, `secure`, which is a boolean `true/false` of the upload's secure status
- when creating a public post with an upload that has already been uploaded and is marked as secure, the post creator will raise an error
- when enabling or disabling the setting on a site with existing uploads, the rake task `uploads:ensure_correct_acl` should be used to update all uploads' secure status and their ACL on S3

Régis Hanol 46d12c5ad3 FIX: properly downsize image on upload
Overwriting the same file with 'convert' is not always working as expected.
Adding a temporary file as the destination of the downsize makes this operation much more reliable.

Also switched to using (the more aggressive) 50% resize instead of halving the number of pixels.

Krzysztof Kotlarek 427d54b2b0 DEV: Upgrading Discourse to Zeitwerk (#8098)
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains. 

We no longer need to use Rails "require_dependency" anywhere and instead can just use standard 
Ruby patterns to require files.

This is a far reaching change and we expect some followups here.

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

Penar Musaraj c50db76f5d FIX: do not treat TIFF, BMP, WEBP as images
Treating TIFF and BMP as images cause us to add them to IMG tags, this is very inconsistent across browsers.

You can still upload these files they will simply not be displayed in IMG tags.

Sam 86255faa08 FEATURE: do not switch to JPEG unless you meet 75k byte savings
This also adjusts the algorithm to expect

- 30% saving for JPEG conversion

AND

- Minimum of 75K bytes saved

The reasoning for increase of saving requirements is cause PNG may have been
uploaded unoptimized, 30% saving on PNG is very possible

Sam 9ab1fb7dfc FEATURE: correctly store width and height on uploads
Previously we used width and height for thumbnails, new code ensures

1. We auto correct width and height
2. We added extra columns for thumbnail_width and height, this is determined
 by actual upload and no longer passed in as a side effect
3. Optimized Image now stores filesize which can be used for analysis, decisions

Also

- fixes Android image manifest as a side effect
- fixes issue where a thumbnail generated that is smaller than the upload is no longer used

Sam 8b5e42ea16 FIX: always test and coerce to image on upload
In the past the filename of the origin was used as the source
for the extension of the file when optimizing on upload.

We now use the actual calculated extension based on upload data.

Guo Xiang Tan 72a3457379 Bump `discourse_image_optim` which uses a global timeout.
Our previous solution has the timeout set at the worker level
which means the total timeout would be X timeout secs * N number of
workers.

Guo Xiang Tan 142571bba0 Remove use of `rescue nil`.
* `rescue nil` is a really bad pattern to use in our code base.
  We should rescue errors that we expect the code to throw and
  not rescue everything because we're unsure of what errors the
  code would throw. This would reduce the amount of pain we face
  when debugging why something isn't working as expexted. I've
  been bitten countless of times by errors being swallowed as a
  result during debugging sessions.
