Review comments at @src/apps/main/database/initialize-virtual-drive-sqlite.ts:
- Line 14: Update the SQLite initialization around PRAGMA synchronous so the
shared AppDataSource retains FULL durability; remove the NORMAL setting or
isolate directory-state storage on a separate connection without changing
durability for other tables.
- Line 13: In the SQLite initialization flow, handle SQLITE_BUSY from the
optional `PRAGMA journal_mode=WAL` so initialization continues to create
`drive_directory_state`. Keep errors from required schema statements propagating
normally.
Review comments at @src/core/bootstrap/register-session-event-handlers.ts:
- Line 27: Track SQLite bootstrap completion separately from AppDataSource
initialization in the session event handler. When handling a later login, retry
initializeVirtualDriveSqlite if bootstrap has not completed, even when
AppDataSource.isInitialized is true, and emit APP_DATA_SOURCE_INITIALIZED only
after SQLite bootstrap succeeds.

What is Changed / Added
Adds
initializeVirtualDriveSqlite, executed immediately afterAppDataSource.initialize()and beforeAPP_DATA_SOURCE_INITIALIZEDis emitted. This guarantees that consumers of the initialized database see the required virtual-drive schema and indexes.Configures SQLite for the upcoming lazy directory hydration workload:
journal_mode=WALto allow readers while background synchronization writes.synchronous=NORMAL,temp_store=MEMORY, andmmap_size=268435456to reduce I/O overhead.busy_timeout=5000to tolerate short-lived write contention instead of failing immediately.wal_autocheckpoint=1000to limit WAL growth.Creates the
drive_directory_statetable:(folder_id, status_scope).children_loaded_atrecords the last successful child listing load.children_last_error_atrecords failed loading attempts.fetch_statestores the latest load state (idleorerror).status_scopecurrently supportsEXISTS, leaving room for other folder views later.Adds indexes for the expected lazy-loading and synchronization access paths:
folderId,status, andupdatedAt.statusandupdatedAt.parentId,status, andupdatedAt.statusandupdatedAt.Adds
createDirectoryStateSqliteRepository, a functional repository factory with explicit dependencies:isFresh({ folderId, statusScope })determines whether a directory listing can be served from local state.markLoaded({ folderId, statusScope })upserts successful hydration state.markError({ folderId, statusScope })records a failed hydration attempt.clear()resets all directory state entries.dataSourceandttlMs; the default freshness TTL is 30 seconds.Adds unit tests for:
Why
The current virtual drive waits for the complete remote synchronization before it can be mounted. For accounts with very large trees, this delays access to all files until the full catalog has been downloaded.
This PR is the persistence foundation for progressive access. The directory-state table will let the next PRs know whether a folder's children were loaded recently, need to be refreshed, or previously failed to load. Combined with the SQLite indexes and WAL configuration, future FUSE operations can hydrate only the folders the user opens while the full remote synchronization continues in the background.
This PR intentionally does not change the mount timing or FUSE behavior yet. It prepares the schema, state contract, and startup ordering required to safely introduce lazy hydration in subsequent PRs.
