Previously we were failing to update the primary key during ensureTable(), which could lead to failures when updating some tables (eg queue_item where we changed keys, and the addition of an autoincrement column failed because it conflicted with the old key).
Now if the key is different, we remove the old key at the start and add the new key at the end of the ALTER TABLE.
Not tested on PostgreSQL -- someone please check whether the alter table 'DROP CONSTRAINT PRIMARY KEY' bit works or if it needs to pull a special name for the key.
On MySQL, dropping uses alter table's 'DROP PRIMARY KEY' special case.
Fetching basic column data and unique indexes. Still needs detail work, multi-value indexes, foreign keys, and distinguishing the primary key.
Since we don't get comments and such, for cleaner comparisons we should probably do a filtering on supported features.
Under MySQL, new tables will be created as InnoDB with UTF-8 (utf8/utf8_bin) same as core tables.
Existing plugin tables will have table engine and default charset/collation updated, and string columns will have charset updated, at checkschema time.
Switched from 'DESCRIBE' to INFORMATION_SCHEMA for pulling column information in order to get charset. A second hit to INFORMATION_SCHEMA is also needed to get table properties.
Indices were only being created at table creation time, which ain't so hot. Now also adding/dropping indices when they change.
Fixed up some schema defs in OStatus plugin that were a bit flaky, causing extra alter tables to be run.
TODO: Generalize this infrastructure a bit more up to base schema & pg schema classes.
* renamed FeedSub plugin to OStatus
* now setting avatar on subscriptions
* general fixes for subscription
* integrated PuSH hub to handle only user timelines on canonical ID url; sends updates directly
* set $config['feedsub']['nohub'] = true to test w/ foreign feeds that don't have hubs (won't actually receive updates though)
* a few bits of code documentation
* HMAC support for verified distributions (safest if sub setup is on HTTPS)
And a couple core changes:
* minimizing HTML output for exceptions in API requests to aid in debugging
* fix for rel=self link in apitimelineuser when id given
This does not not yet include any of the individual subscription management (Salmon notifications for sub/unsub, etc) nor a nice UI for user subscriptions.
Needs some further cleanup to treat posts as status updates instead of link references.
