|

//
|

// - (mDBConn && asyncThread): The expected case where we are either an
|
|
|
|
// async connection or a sync connection that has been used asynchronously.
|
|
|
|
// Either way the caller must call us and not Close(). Nothing surprising
|
|
|
|
// about this. We'll dispatch AsyncCloseConnection to the already-existing
|
|
|
|
// async thread.
|
|
|
|
//
|
|
|
|
// - (mDBConn && !asyncThread): A somewhat unusual case where the caller
|
|
|
|
// opened the connection synchronously and was planning to use it
|
|
|
|
// asynchronously, but never got around to using it asynchronously before
|
|
|
|
// needing to shutdown. This has been observed to happen for the cookie
|
|
|
|
// service in a case where Firefox shuts itself down almost immediately
|
|
|
|
// after startup (for unknown reasons). In the Firefox shutdown case,
|
|
|
|
// we may also fail to create a new async execution thread if one does not
|
|
|
|
// already exist. (nsThreadManager will refuse to create new threads when
|
|
|
|
// it has already been told to shutdown.) As such, we need to handle a
|
|
|
|
// failure to create the async execution thread by falling back to
|
|
|
|
// synchronous Close() and also dispatching the completion callback because
|
|
|
|
// at least Places likes to spin a nested event loop that depends on the
|
|
|
|
// callback being invoked.
|
|
|
|
//
|
|
|
|
// Note that we have considered not trying to spin up the async execution
|
|
|
|
// thread in this case if it does not already exist, but the overhead of
|
|
|
|
// thread startup (if successful) is significantly less expensive than the
|
|
|
|
// worst-case potential I/O hit of synchronously closing a database when we
|
|
|
|
// could close it asynchronously.
|
|
|
|
//
|
|
|
|
// - (!mDBConn && asyncThread): This happens in some but not all cases where
|
|
|
|
// OpenAsyncDatabase encountered a problem opening the database. If it
|
|
|
|
// happened in all cases AsyncInitDatabase would just shut down the thread
|
|
|
|
// directly and we would avoid this case. But it doesn't, so for simplicity
|
|
|
|
// and consistency AsyncCloseConnection knows how to handle this and we
|
|
|
|
// act like this was the (mDBConn && asyncThread) case in this method.
|
|
|
|
//
|
|
|
|
// - (!mDBConn && !asyncThread): The database was never successfully opened or
|
|
|
|
// Close() or AsyncClose() has already been called (at least) once. This is
|
|
|
|
// undeniably a misuse case by the caller. We could optimize for this
|
|
|
|
// case by adding an additional check of mAsyncExecutionThread without using
|
|
|
|
// getAsyncExecutionTarget() to avoid wastefully creating a thread just to
|
|
