New Revision: 251736
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=251736
Log:
Add new unit test for stringfields.
(Copied from reviewboard)
Tests the following:
1. Basic allocation and setting of string fields.
2. Shrinking a string field and re-expanding it.
3. Growing the last allocation in a string field pool.
4. Setting a string to a large value such that a new string field pool must be
allocated.
In each part, we make sure that the string field is accurate (has the correct
value in it), make sure that the 2 bytes before the string field has the correct
capacity for the field, and for tests 2-4, we make sure that the string field is
where we expect it to be in memory.
Also tested:
5. Shrinking a string field and partially re-expanding it.
6. Setting strings in such a way as to create three separate string field pools
and then removing the middle pool.
There is a bug fix in the init function, which ensures the embedded_pool is set
to NULL which is important for stack allocated structures.
