Subject [jira] [Commented] (DIRECTMEMORY-40) Pointers merging with adjacent free pointers when freeing.
Date Thu, 01 Mar 2012 11:54:02 GMT

    [ https://issues.apache.org/jira/browse/DIRECTMEMORY-40?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13219976#comment-13219976
] 

Hudson commented on DIRECTMEMORY-40:
------------------------------------

Integrated in directmemory-trunk #160 (See [https://builds.apache.org/job/directmemory-trunk/160/])
    DIRECTMEMORY-40, DIRECTMEMORY-60 : separate responsabilities more clearly, set allocation
with merging pointers as the default one, add a SLAB's style allocator (fixed buffer size),
mark OffHeapMemoryBuffer as deprecated (Revision 1295522)

     Result = SUCCESS

> 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.
