* Move current work into single branch
* Initial massaging of clientapi etc (not working yet)
* Interfaces for accounts/devices databases
* Duplicate postgres package for sqlite3 (no changes made to it yet)
* Some keydb, accountdb, devicedb, common partition fixes, some more syncapi tweaking
* Fix accounts DB, device DB
* Update naffka dependency for SQLite
* Naffka SQLite
* Update naffka to latest master
* SQLite support for federationsender
* Mostly not-bad support for SQLite in syncapi (although there are problems where lots of events get classed incorrectly as backward extremities, probably because of IN/ANY clauses that are badly supported)
* Update Dockerfile -> Go 1.13.7, add build-base (as gcc and friends are needed for SQLite)
* Implement GET endpoints for account_data in clientapi
* Nuke filtering for now...
* Revert "Implement GET endpoints for account_data in clientapi"
This reverts commit 4d80dff458
.
* Implement GET endpoints for account_data in clientapi (#861)
* Implement GET endpoints for account_data in clientapi
* Fix accountDB parameter
* Remove fmt.Println
* Fix insertAccountData SQLite query
* Fix accountDB storage interfaces
* Add empty push rules into account data on account creation (#862)
* Put SaveAccountData into the right function this time
* Not sure if roomserver is better or worse now
* sqlite work
* Allow empty last sent ID for the first event
* sqlite: room creation works
* Support sending messages
* Nuke fmt.println
* Move QueryVariadic etc into common, other device fixes
* Fix some linter issues
* Fix bugs
* Fix some linting errors
* Fix errcheck lint errors
* Make naffka use postgres as fallback, fix couple of compile errors
* What on earth happened to the /rooms/{roomID}/send/{eventType} routing
