Subject [jira] [Updated] (DIRECTMEMORY-40) Pointers merging with adjacent free pointers when freeing.
Date Thu, 29 Dec 2011 15:57:30 GMT

     [ https://issues.apache.org/jira/browse/DIRECTMEMORY-40?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benoit Perroud updated DIRECTMEMORY-40:
---------------------------------------

    Attachment: OffHeapLinkedMemoryBuffer.java

Latest version. Bug corrected when merging pointers. Use TreeMap instead of ConcurrentSkipListMap
because synchronization is done through a lock.

> If one allocates lot of small objects till the buffer is full, and then free those objects,
pointers are never merged together to allow further creation of bigger objects.
