Notable changes:
* Imports a lot more tables from core and plugins
* site settings
* uploads with necessary upload references
* groups and group members
* user profiles
* user options
* user fields & values
* muted users
* user notes (plugin)
* user followers (plugin)
* user avatars
* tag groups and tags
* tag users (notification settings for tags / user)
* category permissions
* polls with options and votes
* post votes (plugin)
* solutions (plugin)
* gamification scores (plugin)
* events (plugin)
* badges and badge groupings
* user badges
* optimized images
* topic users (notification settings for topics)
* post custom fields
* permalinks and permalink normalizations
* It creates the `migration_mappings` table which is used to store the mapping for a handful of imported tables
* Detects duplicate group names and renames them
* Pre-cooking for attachments, images and mentions
* Outputs instructions when gems are missing
* Supports importing uploads from a DB generated by `uploads_importer.rb`
* Checks that all required plugins exists and enables them if needed
* A couple of optimizations and additions in `import.rake`
* Allow taking table prefix from env var
* FIX: remove unused column references
The columns `filedata` and `extension` are not present in a v4.2.4
database, and they aren't used in the method anyways.
* FIX: report progress for tables without imported_id
* FIX: effectively check for AR validation errors
NOTE: other migration scripts also have this problem; see /t/58202
* FIX: properly count Posts when importing attachments
* FIX: improve logging
* Remove leftover comment
* FIX: show progress when exporting Permalink file
* PERF: stream Permalink file
The current way results in tons of memory usage; write once per line instead
* Document fixes needed
* WIP - deduplicate category names
* Ignore non alphanumeric chars for grouping
* FIX: properly deduplicate user emails by merging accounts
* FIX: don't merge empty UserEmails
* Improve logging
* Merge users AFTER fixing primary key sequences
* Parallelize user merging
* Save duplicated users structure for debugging purposes
* Add progress logging for the (multiple hour) user merging step
`ActiveRecord::Base.connection_config` has been deprecated since Rails
6.1 and was completely removed from Rails 7.
Instead we need to use
`ActiveRecord::Base.connection_db_config.configuration_hash`.
Import scripts were forgotten when we did the Rails 7 upgrade, this
patch fixes them.
We validate the *format* of email addresses in many places with a match against
a regex, often with very slightly different syntax.
Adding a separate EmailAddressValidator simplifies the code in a few spots and
feels cleaner.
Deprecated the old location in case someone is using it in a plugin.
No functionality change is in this commit.
Note: the regex used at the moment does not support using address literals, e.g.:
* localpart@[192.168.0.1]
* localpart@[2001:db8::1]
This is a pretty straightforward bulk importer, just tailored to the vBulletin 5 database structure.
Also made a few minor improvements to the base importer -- should be self explanatory in the code.
Adjustments to the base:
1. PG connection doesn't require host - it was broken on import droplet
2. Drop `topic_reply_count` - it was removed here - https://github.com/discourse/discourse/blob/master/db/post_migrate/20200513185052_drop_topic_reply_count.rb
3. Error with `backtrace.join("\n")` -> `e.backtrace.join("\n")`
4. Correctly link the user and avatar to quote block
Adjustments to vanilla:
1. Top-level Vanilla categories are valid categories
2. Posts have `format` column which should be used to decide if the format is HTML or Markdown
3. Remove no UTF8 characters
4. Remove not supported HTML elements like `font` `span` `sub` `u`
- Stream the queries that load the imported_ids
- Use an array instead of a hash for keeping the mapping between imported_ids and new ids
- Ensure we always treat the imported_ids as integers instead of strings
We have the `# frozen_string_literal: true` comment on all our
files. This means all string literals are frozen. There is no need
to call #freeze on any literals.
For files with `# frozen_string_literal: true`
```
puts %w{a b}[0].frozen?
=> true
puts "hi".frozen?
=> true
puts "a #{1} b".frozen?
=> true
puts ("a " + "b").frozen?
=> false
puts (-("a " + "b")).frozen?
=> true
```

We like to stay as close as possible to latest with rubocop cause the cops
get better.
This update required some code changes, specifically the default is to avoid
explicit returns where implicit is done
Also this renames a few rules
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
