* 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 4d80dff4583d278620d9b3ed437e9fcd8d4674ee. * 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 Co-authored-by: Neil Alexander <neilalexander@users.noreply.github.com>
