From d88282af407fc3654826c29e0fe1c717143c93f0 Mon Sep 17 00:00:00 2001 From: Matthew Jordan Date: Fri, 31 Oct 2014 03:26:28 +0000 Subject: channels/sip/reqresp_parser: Fix unit tests for r426594 When r426594 was made, it did not take into account a unit test that verified that the function properly populated the unsupported buffer. The function would previously memset the buffer if it detected it had any contents; since this function can now be called iteratively on successive headers, the unit tests would now fail. This patch updates the unit tests to reset the buffer themselves between successive calls, and updates the documentation of the function to note that this is now required. ........
