Very short und maybe a bit chaotic...
|
|
|
|
There are some [style patches](https://repo.oe7drt.net/dominic/mastodon-styles)
|
|
available for plain mastodon for those that would want to have a look at them.
|
|
|
|

There are several scripts executable with `RAILS_ENV=production bundle exec rails c`,
|
|
for convenience laid out here with minor corrections. **Do not execute these
|
|
without understanding what they do!**:
|
|
|
|
Deleting all cached media attachments from external servers to allow web app
|
|
to re-fetch them when they are queried. At least on my instance this is really
|
|
slow, takes tens of seconds per attachment (is this the same as `tootctl media
|
|
remove`?):
|
|
|
|
```ruby
|
|
MediaAttachment.cached.where.not(remote_url: '').each do |attachment|
|
|
attachment.file.destroy
|
|
attachment.thumbnail.destroy
|
|
attachment.save
|
|
end
|
|
```
|
|
|
|
Deleting and re-downloading all cached remote emojis. This apparently has a
|
|
problem that the local URLs for the cached emojis change, and the URLs aren't
|
|
updated to the fetched profile headers. I suppose this should be done before
|
|
the next steps, assuming the cached local emoji URLs are set up correctly to
|
|
the profile headers and names at the time of fetching. This doesn't seem to
|
|
work though, maybe `tootctl emoji purge --remote-only` would be better:
|
|
|
|
```ruby
|
|
CustomEmoji.remote.where.not(image_file_name: nil).where.not(image_remote_url: '').each do |emoji|
|
|
emoji.image.destroy
|
|
emoji.image.save
|
|
emoji.download_image!
|
|
end
|
|
```
|
|
|
|
Deleting all remote profile avatars, and re-fetching them. Are these two the
|
|
same as `tootctl accounts refresh --all`?:
|
|
|
|
```ruby
|
|
Account.remote.where.not(avatar_file_name: nil).where.not(avatar_remote_url: '').each do |a|
|
|
a.avatar.destroy
|
|
a.save
|
|
a.download_avatar!
|
|
end
|
|
```
|
|
|
|
Deleting all remote profile headers, and re-fetching them. Hopefully this
|
|
uses/updates the newly fetched local cached emoji URLs, and also includes the
|
|
profile name as they often contain emojis:
|
|
|
|
```ruby
|
|
Account.remote.where.not(header_file_name: nil).where.not(header_remote_url: '').each do |a|
|
|
a.header.destroy
|
|
a.save
|
|
a.download_header!
|
|
end
|
|
```
|
|
|
|
It would be awesome to get tooling for these to `tootctl`. That said, I'm not
|
|
entirely sure if destroying the entities is necessary before downloading them
|
|
again, and perhaps we could use `remove_entity_cache` instead. I'm not very well
|
|
acquainted with the codebase.
