Sync Settings (#2478) * Sync Settings * Added valueHandlers and Database singleton Some issues remain, need a way to comparing incoming sql.DB to check if the connection is to a different file or not. Maybe make singleton instance per filename * Added functionality to check the sqlite filename * Refactor of Database.SaveSyncSettings to be used as a handler * Implemented inteface for setting sync protobuf factories * Refactored and completed adhoc send setting sync * Tidying up * Immutability refactor * Refactor settings into dedicated package * Breakout structs * Tidy up * Refactor of bulk settings sync * Bug fixes * Addressing feedback * Fix code dropped during rebase * Fix for db closed * Fix for node config related crashes * Provisional fix for type assertion - issue 2 * Adding robust type assertion checks * Partial fix for null literal db storage and json encoding * Fix for passively handling nil sql.DB, and checking if elem has len and if len is 0 * Added test for preferred name behaviour * Adding saved sync settings to MessengerResponse * Completed granular initial sync and clock from network on save * add Settings to isEmpty * Refactor of protobufs, partially done * Added syncSetting receiver handling, some bug fixes * Fix for sticker packs * Implement inactive flag on sync protobuf factory * Refactor of types and structs * Added SettingField.CanSync functionality * Addressing rebase artifact * Refactor of Setting SELECT queries * Refactor of string return queries * VERSION bump and migration index bump * Deactiveate Sync Settings * Deactiveated preferred_name and send_status_updates Co-authored-by: Andrea Maria Piana <andrea.maria.piana@gmail.com>

Sync Settings (#2478) * Sync Settings * Added valueHandlers and Database singleton Some issues remain, need a way to comparing incoming sql.DB to check if the connection is to a different file or not. Maybe make singleton instance per filename * Added functionality to check the sqlite filename * Refactor of Database.SaveSyncSettings to be used as a handler * Implemented inteface for setting sync protobuf factories * Refactored and completed adhoc send setting sync * Tidying up * Immutability refactor * Refactor settings into dedicated package * Breakout structs * Tidy up * Refactor of bulk settings sync * Bug fixes * Addressing feedback * Fix code dropped during rebase * Fix for db closed * Fix for node config related crashes * Provisional fix for type assertion - issue 2 * Adding robust type assertion checks * Partial fix for null literal db storage and json encoding * Fix for passively handling nil sql.DB, and checking if elem has len and if len is 0 * Added test for preferred name behaviour * Adding saved sync settings to MessengerResponse * Completed granular initial sync and clock from network on save * add Settings to isEmpty * Refactor of protobufs, partially done * Added syncSetting receiver handling, some bug fixes * Fix for sticker packs * Implement inactive flag on sync protobuf factory * Refactor of types and structs * Added SettingField.CanSync functionality * Addressing rebase artifact * Refactor of Setting SELECT queries * Refactor of string return queries * VERSION bump and migration index bump * Deactiveate Sync Settings * Deactiveated preferred_name and send_status_updates Co-authored-by: Andrea Maria Piana <andrea.maria.piana@gmail.com>

Anon Metrics Broadcast (#2198) * Protobufs and adapters * Added basic anon metric service and config init * Added fibonacci interval incrementer * Added basic Client.Start func and integrated interval incrementer * Added new processed field to app metrics table * Added id column to app metrics table * Added migration clean up * Added appmetrics GetUnprocessed and SetToProcessedByIDs and tests There was a wierd bug where metrics in the db that did not explicitly insert a value would be NULL, so could not be found by . In addition I've added a new primary id field to the app_metrics table so that updates could be done against very specific metric rows. * Updated adaptors and db to handle proto_id I need a way to distinguish individual metric items from each other so that I can ignore the ones that have been seen before. * Moved incrementer into dedicated file * Resolve incrementer test fail * Finalised the main loop functionality * Implemented delete loop framework * Updated adaptors file name * Added delete loop delay and quit, and tweak on RawMessage gen * Completed delete loop logic * Added DBLock to prevent deletion during mainLoop * Added postgres DB connection, integrated into anonmetrics.Server * Removed proto_id from SQL migration and model * Integrated postgres with Server and updated adaptors * Function name update * Added sample config files for client and server * Fixes and testing for low level e2e * make generate * Fix lint * Fix for receiving an anonMetricBatch not in server mode * Postgres test fixes * Tidy up, make vendor and make generate * delinting * Fixing database tests * Attempted fix of does: cannot open `does' (No such file or directory) not: cannot open `not' (No such file or directory) exist: cannot open `exist' (No such file or directory) error on sql resource loas * Moved all anon metric postgres migration logic and sources into a the protocol/anonmetrics package or sub packages. I don't know if this will fix the does: cannot open `does' (No such file or directory) not: cannot open `not' (No such file or directory) exist: cannot open `exist' (No such file or directory) error that happens in Jenkins but this could work * Lint for the lint god * Why doesn't the linter list all its problems at once? * test tweaks * Fix for wakuV2 change * DB reset change * Fix for postgres db migrations fails * More robust implementation of postgres test setup and teardown * Added block for anon metrics functionality * Version Bump to 0.84.0 * Added test to check anon metrics broadcast is deactivated * Protobufs and adapters * Added basic anon metric service and config init * Added new processed field to app metrics table * Added id column to app metrics table * Added migration clean up * Added appmetrics GetUnprocessed and SetToProcessedByIDs and tests There was a wierd bug where metrics in the db that did not explicitly insert a value would be NULL, so could not be found by .
