Replace the old IQDB API client with a new client for the new forked
version of IQDB at https://github.com/danbooru/iqdb.
Changes:
* The /iqdb_queries endpoint now returns `hash` and `signature` fields.
The `signature` is the full decoded Haar signature, while the `hash`
is a encoded version of the signature.
* The /iqdb_queries endpoint no longer returns `width` and `height`
fields in the response (these were always 128x128).
* We no longer need the IQDBs frontend server, now we talk to the IQDB
instance directly.
* We no longer send add/remove image commands to IQDB through AWS SQS,
now we send them to IQDB directly. They are sent in a delayed job so
that if IQDB is down, uploading images is still possible, the add
image commands will just get queued up.
* Fix a bug where regenerating an image's thumbnails didn't regenerate
IQDB, because IQDB silently ignored add image commands when the image
already existed in the database.
Fix docker-compose sometimes failing to restart the app. Puma's pidfile
was stored in /tmp, which was persisted across restarts, which caused
restarts to fail because the pidfile already existed. The fix is to
mount /tmp as a tmpfs.
Fix an issue where the New Relic agent always started in the production
environment, even when a license key wasn't configured.
Also make the New Relic agent log to stdout instead of log/newrelic_agent.log.
Use the prebuilt Docker images instead of building them locally in the
Docker Compose script. This is faster, but it means that local changes
to the code will be ignored.
* Fix installing the wrong Docker package on Ubuntu.
* Fix the package install steps asking for confirmation.
* Fix missing sudo calls in a couple places.
Fix the quickstart command in the README not working for Ubuntu 18.04.
This was because the Docker Compose file was set to version 3.7, but
Ubuntu 18.04 ships an older version of Docker Compose that only supports
version 3.4.
When a user tries to change their email, redirect them to the confirm
password page (like Github's sudo mode) instead of having them re-enter
their password on the change email page. This is the same thing we do
when a user updates their API keys. This way we have can use the same
confirm password authentication flow for everything that needs a
password.
* Show the ban length instead of the ban expiration date in ban notices.
* Fix the ban notice to not say "Your account has been temporarily
banned" when it's a permanent ban.
Show the HTTP request headers and the client IP on the /status page.
This is for debugging request headers added by reverse proxies such as
Cloudflare and Nginx, and for making sure the client IP is correctly set
by the X-Forwarded-For header.
