From 2d26a2da1f8fbcf61b6b9f1a8b90e255a68a3252 Mon Sep 17 00:00:00 2001 From: Jeff Peeler Date: Wed, 10 Mar 2010 23:15:55 +0000 Subject: 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.
