enableSqliteWriteAheadLogging()

void enableSqliteWriteAheadLogging ( )

Enable the "Write-Ahead Logging" (WAL) feature 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.
