<p>Previous releases of Berkeley DB returned the system error EIO when the
|
||
memp_fget function was called to retrieve a page, the page did not
|
||
exist, and the <code class="literal">DB_MPOOL_CREATE</code> flag was not set. In the 3.3
|
||
release, the error <code class="literal">DB_PAGE_NOTFOUND</code> is returned instead, to
|
||
allow applications to distinguish between recoverable and
|
||
non-recoverable errors. Applications calling the memp_fget function
|
||
and checking for a return of EIO should check for
|
||
<code class="literal">DB_PAGE_NOTFOUND</code> instead.</p>
|
||
<p>Previous releases of Berkeley DB treated filesystem I/O failure (the most
|
||
common of which the filesystem running out of space), as a fatal error,
|
||
returning <a href="../programmer_reference/program_errorret.html#program_errorret.DB_RUNRECOVERY" class="olink">DB_RUNRECOVERY</a>. When a filesystem failure happens in
|
||
the 3.3 release Berkeley DB returns the underlying system error (usually EIO),
|
||
but can continue to run. Applications should abort any enclosing
|
||
transaction when a recoverable system error occurs in order to recover
|
||
from the error.</p>
