Subject Speed up 'apr_array_cat'
Date Tue, 09 Aug 2011 05:20:44 GMT
Hi,

the function apr_array_cat could be speed up a bit by resetting only the
memory that need to be.

Actually, when there is not enough space in the destination table we do :
    - allocate new memory and set it all to 0
    - copy the dst table to the new location
    - copy the src table after the dst table

We could :
   - allocate new memory
   - reset the memory that will remain uninitialised after copying dst and
src tables  <------------
   - copy the dst table to the new location
   - copy the src table after the dst table

Doing so, avoid the need to erase some memory.

A proposed, untested, patch is attached.

Best regards,
CJ
