1809 // - (mDBConn && asyncThread): The expected case where we are either an
1810 // async connection or a sync connection that has been used asynchronously.
1811 // Either way the caller must call us and not Close(). Nothing surprising
1812 // about this. We'll dispatch AsyncCloseConnection to the already-existing
1813 // async thread.
1814 //
1815 // - (mDBConn && !asyncThread): A somewhat unusual case where the caller
1816 // opened the connection synchronously and was planning to use it
1817 // asynchronously, but never got around to using it asynchronously before
1818 // needing to shutdown. This has been observed to happen for the cookie
1819 // service in a case where Firefox shuts itself down almost immediately
1820 // after startup (for unknown reasons). In the Firefox shutdown case,
1821 // we may also fail to create a new async execution thread if one does not
1822 // already exist. (nsThreadManager will refuse to create new threads when
1823 // it has already been told to shutdown.) As such, we need to handle a
1824 // failure to create the async execution thread by falling back to
1825 // synchronous Close() and also dispatching the completion callback because
1826 // at least Places likes to spin a nested event loop that depends on the
1827 // callback being invoked.
1828 //
1829 // Note that we have considered not trying to spin up the async execution
1830 // thread in this case if it does not already exist, but the overhead of
1831 // thread startup (if successful) is significantly less expensive than the
1832 // worst-case potential I/O hit of synchronously closing a database when we
1833 // could close it asynchronously.
1834 //
1835 // - (!mDBConn && asyncThread): This happens in some but not all cases where
1836 // OpenAsyncDatabase encountered a problem opening the database. If it
1837 // happened in all cases AsyncInitDatabase would just shut down the thread
1838 // directly and we would avoid this case. But it doesn't, so for simplicity
1839 // and consistency AsyncCloseConnection knows how to handle this and we
1840 // act like this was the (mDBConn && asyncThread) case in this method.
1841 //
1842 // - (!mDBConn && !asyncThread): The database was never successfully opened or
1843 // Close() or AsyncClose() has already been called (at least) once. This is
1844 // undeniably a misuse case by the caller. We could optimize for this
1845 // case by adding an additional check of mAsyncExecutionThread without using
1846 // getAsyncExecutionTarget() to avoid wastefully creating a thread just to
