Fix temp files generated during the upload process not being cleaned up quickly enough. This included
downloaded files, generated preview images, and Ugoira video conversions.
Before we relied on `Tempfile` cleaning up files automatically. But this only happened when the
Tempfile object was garbage collected, which could take a long time. In the meantime we could have
hundreds of megabytes of temp files hanging around.
The fix is to explicitly close temp files when we're done with them. But the standard `Tempfile`
class doesn't immediately delete the file when it's closed. So we also have to introduce a
Danbooru::Tempfile wrapper that deletes the tempfile as soon as it's closed.
Refactor StorageManager to remove all image URL generation code. Instead
the image URL generation code lives in MediaAsset.
Now StorageManager is only concerned with how to read and write files to
remote storage backends like S3 or SFTP, not with how image URLs should
be generated. This way the file storage code isn't tightly coupled to
posts, so it can be used to store any kind of file, not just images
belonging to posts.
Move more of the file-handling logic from UploadService and
StorageManager into MediaAsset. This is part of refactoring posts and
uploads to allow multiple images per post.
Remove StorageManager::Hybrid and StorageManager::Match. These were used
to store uploads on different servers based on the post ID or file
sample type. This is no longer used in production because in hindsight
it's a lot more difficult to manage uploads when they're fragmented
across different servers.
If you need this, you can do tricks with network filesystems to get the
same effect. For example, if you want to store some files on server A
and others on server B, then mount servers A and B as network
filesystems (with e.g. sshfs, Samba, NFS, etc), and use symlinks to
point subdirectories at either server A or B.
Always store original files in `public/data/original` instead of directly in
`public/data`. Previously this was optional and defaulted to off.
Downstream boorus will need to either move all images in the
`public/data` directory to `public/data/original`, or symlink the
`public/data/original` directory to the toplevel `public/data` directory:
ln -s . /path/to/danbooru/public/data/original
This to simplify file layout. This option existed because in the past we
stored original files in different locations on different servers (for
no particular reason).
Bug: Replacing posts hosted on cdn.donmai.us didn't work.
Cause: Original files on cdn.donmai.us are hosted under /var/www/danbooru/original/, but replacements
were trying to store them directly under /var/www/danbooru, which failed with a permission error.
We were trying to store them in the wrong directory because we didn't respect the `original_subdir`
option when generating file paths.
Fail loudly if we forget to whitelist a param instead of silently
ignoring it.
misc models: convert to strong params.
artist commentaries: convert to strong params.
* Disallow changing or setting post_id to a nonexistent post.

* Disallow setting `is_banned` in create/update actions. Changing it
this way instead of with the ban/unban actions would leave the artist in
a partially banned state.
