Improves the generic database used by some import scripts:
* Adds additional columns for users
* Adds support for attachments
* Allows setting the data type for keys (numeric or string) to ensure correct sorting
* Log errors when mapping of posts, messages, etc. fails
* Allow permalink normalizations for old subfolder installation
* Disable importing of polls for now. It's broken.
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.
Changes to functionality
- Removed syncing of user metadata including gender, location etc.
These are no longer available to standard Facebook applications.
- Removed the remote 'revoke' functionality. No other providers have
it, and it does not appear to be standard practice in other apps.
- The 'facebook_no_email' event is no longer logged. The system can
cope fine with a missing email address.
Data is migrated to the new user_associated_accounts table.
facebook_user_infos can be dropped once we are confident the data has
been migrated successfully.
This is useful for cases where you want to add resiliency to DNS lookups
for redis and postgres, so they will continue to work even if there is
a DNS outage
This restores the previous functionality. The script now allows the following options:
* `discourse backup` (uses the system generated filename)
* `discourse backup <some_filename>` (uses the provided filename)
* `discourse backup </some/path/to/filename>` (moves the backup to the provided path with the given filename)
Remote backup stores do not support the last option.
Some file extensions (like `.tar.gz`) are automatically removed from the provided filename.
- By default, behaviour is not changed: tags are made lowercase upon creation and edit.
- If force_lowercase_tags is disabled, then mixed case tags are allowed.
- Tags must remain case-insensitively unique. This is enforced by ActiveRecord and Postgres.
- A migration is added to provide a `UNIQUE` index on `lower(name)`. Migration includes a safety to correct any current tags that do not meet the criteria.
- A `where_name` scope is added to `models/tag.rb`, to allow easy case-insensitive lookups. This is used instead of `Tag.where(name: "blah")`.
- URLs remain lowercase. Mixed case URLs are functional, but have the lowercase equivalent as the canonical.
