Joshua Colp	e40fddbeb5	tests/test_sorcery_memory_cache_thrash: Improve termination process. When terminating the threads thrashing a sorcery memory cache each would be told to stop and then we would wait on them. During at least one thrashing test this was problematic due to the specific usage pattern in use. It would take some time for termination of the thread to occur. This would occur due to contention between the threads retrieving and the threads updating the cache. As the retrieving threads are given priority it may be some time before the updating threads are able to proceed. This change makes it so all threads are told to stop and then each are joined to ensure they stop. This way all the threads should stop at around the same time instead of waiting for one to stop, the next to stop, then the next, and so on. As a result of this the execution time for each thrash test is much closer to their expected value than previously seen as well. Change-Id: I04a53470b0ea4170b8819180b0bd7475f3642827	10 years ago

Joshua Colp	028edae82e	test_sorcery_memory_cache_thrash: Add unit tests for thrashing the memory cache. This change adds a CLI command which can perform memory cache thrashing as well as unit tests which perform thrashing under the following configurations: 1. Low number of unique objects that go stale after 1 second 2. Low number of unique objects that expire after 1 second 3. Low number of unique objects which are constantly updated 4. Large number of unique objects which exceed a defined cache size 5. Large number of unique objects which exceed a defined cache size that also expire and go stale rapidly 6. Large number of unique objects which expire and go stale rapidly 7. Large number of unique objects For all of the above there are a large number of threads constantly attempting to retrieve random objects and each test runs for a few seconds.

tests/test_sorcery_memory_cache_thrash: Improve termination process.

When terminating the threads thrashing a sorcery memory cache each
would be told to stop and then we would wait on them. During at
least one thrashing test this was problematic due to the specific
usage pattern in use. It would take some time for termination of the
thread to occur.

This would occur due to contention between the threads retrieving
and the threads updating the cache. As the retrieving threads are
given priority it may be some time before the updating threads
are able to proceed.

This change makes it so all threads are told to stop and then each
are joined to ensure they stop. This way all the threads should
stop at around the same time instead of waiting for one to stop,
the next to stop, then the next, and so on. As a result of this
the execution time for each thrash test is much closer to their
expected value than previously seen as well.

Unit tests: Fix more unit test description strings.

Analyzing the code shows that the unit test summary and description
strings should not end with a new-line character.  Where these strings are
used in the code a new-line is provided for output.

This change adds a CLI command which can perform memory cache thrashing as well
as unit tests which perform thrashing under the following configurations:

1. Low number of unique objects that go stale after 1 second
2. Low number of unique objects that expire after 1 second
3. Low number of unique objects which are constantly updated
4. Large number of unique objects which exceed a defined cache size
5. Large number of unique objects which exceed a defined cache size
   that also expire and go stale rapidly
6. Large number of unique objects which expire and go stale rapidly
7. Large number of unique objects

For all of the above there are a large number of threads constantly
attempting to retrieve random objects and each test runs for a few
seconds.
