<p>As part of implementing support for multi-version concurrency control,
|
|||
|
|
the <a href="../api_reference/C/mempfget.html#fget_DB_MPOOL_DIRTY" class="olink">DB_MPOOL_DIRTY</a> flag is now specified to the
|
|||
|
|
<a href="../api_reference/C/mempfget.html" class="olink">DB_MPOOLFILE->get()</a> instead of <a href="../api_reference/C/mempput.html" class="olink">DB_MPOOLFILE->put()</a>, and the
|
|||
|
|
DB_MPOOLFILE->set method has been removed. In addition, a new
|
|||
|
|
transaction handle parameter has been added to the <a href="../api_reference/C/mempfget.html" class="olink">DB_MPOOLFILE->get()</a> method.</p>
|
|||
|
|
<p>The DB_MPOOL_CLEAN flag is no longer supported.</p>
|
|||
|
|
<p>Applications which use the memory pool API directly should update to
|
|||
|
|
the new API in order to use 4.5.</p>
