◆ enableSqliteWriteAheadLogging()

void enableSqliteWriteAheadLogging ( )
private

Enable the "Write-Ahead Logging" (WAL) featur of SQLite.

Note
LibrePCB requires to enable WAL to avoid blocking readers by writers. If not enabled, the library scanner would also block all read-only accesses to the library database.
