<p>In previous Berkeley DB releases, the <a href="../api_reference/C/dbclose.html" class="olink">DB->close()</a> and <a href="../api_reference/C/dbsync.html" class="olink">DB->sync()</a> methods
|
|||
|
|
discarded any return of DB_INCOMPLETE from the underlying buffer
|
|||
|
|
pool interfaces, and returned success to its caller. (The
|
|||
|
|
DB_INCOMPLETE error will be returned if the buffer pool functions
|
|||
|
|
are unable to flush all of the database's dirty blocks from the pool.
|
|||
|
|
This often happens if another thread is reading or writing the database's
|
|||
|
|
pages in the pool.)</p>
|
|||
|
|
<p>In the 3.X release, <a href="../api_reference/C/dbsync.html" class="olink">DB->sync()</a> and <a href="../api_reference/C/dbclose.html" class="olink">DB->close()</a> will return
|
|||
|
|
DB_INCOMPLETE to the application. The best solution is to not
|
|||
|
|
call <a href="../api_reference/C/dbsync.html" class="olink">DB->sync()</a> with the <a href="../api_reference/C/dbclose.html#dbclose_DB_NOSYNC" class="olink">DB_NOSYNC</a> flag to the
|
|||
|
|
<a href="../api_reference/C/dbclose.html" class="olink">DB->close()</a> method when multiple threads are expected to be accessing the
|
|||
|
|
database. Alternatively, the caller can ignore any error return of
|
|||
|
|
DB_INCOMPLETE.</p>
