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

Guo Xiang Tan feb731bffd FIX: Regenerate optimized images instead of migrating from old scheme.
`OptimizedImage.migrate_to_new_scheme` was optimizing optimized images
which we don't need to do. Regnerating the optimized image is way easier.

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 7e4a43afc6 PERF: run ImageMagick conversions with nice 10
This lowers the priority of all image resizes so they do not clog CPU on
machines running low on resources

Sam 9c91e68351 PERF: remove image optimization throttling from Sidekiq
Previously we only allowed one image optimization per machine, this meant there
was cross talk between avatar resizing and Sidekiq. This could lead to large
amounts of starvation when optimized image version changed which in turn could
block the Sidekiq queue.

This increases amount of allowed load on machines but this is preferable to
having crosstalk between avatar resizing and Sidekiq.

Sam 570877da3c FEATURE: store thumbnail algorithm version in optimized image table
Previously we had no idea what algorithm generated thumbnails, this starts tracking the version.

We also bumped up the version to force all optimized images to be generated. This is important cause we recently introduced pngquant which results in much smaller images.

Sam 766e67ce57 FEATURE: introduce lossy color optimization on resized pngs
This feature ensures optimized images run via pngquant, this results extreme amounts of savings for resized images. Effectively the only impact is that the color palette on small resized images is reduced to 256.

To ensure safety we only apply this optimisation to images smaller than 500k.

This commit also makes a bunch of image specs less fragile.

Robin Ward 662cfc416b FEATURE: Show a blurry preview when lazy loading images
This generates a 10x10 PNG thumbnail for each lightboxed image.
If Image Lazy Loading is enabled (IntersectionObserver API) then
we'll load the low res version when offscreen. As the image scrolls
in we'll swap it for the high res version.

We use a WeakMap to track the old image attributes. It's much less
memory than storing them as `data-*` attributes and swapping them
back and forth all the time.

Sam 0a442e319c FIX: correct svg handling for images
We regressed and optimized images no longer worked with svg

The following adds the correct logic to simply copy file for svgs
and bypasses resizing for svg avatars

Sam 5302709343 FIX: in redis readonly raise an exception from DistributedMutex
If we detect redis is in readonly we can not correctly get a mutex
raise an exception to notify caller

When getting optimized images avoid the distributed mutex unless
for some reason it is the first call and we need to generate a thumb

In redis readonly no thumbnails will be generated
2018-09-19 15:50:58 +10:00
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 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.

demand so they do not dominate the machine.
