tests: Fix queries_captured to clear cache up front. Before this change we were clearing the cache on every SQL usage. The code to do this was added in February 2017 in 6db4879f9c9fd6941d3aa2af6138ea75aa6675a6. Now we clear the cache just one time, but before the action/request under test. Tests that want to count queries with a warm cache now specify keep_cache_warm=True. Those tests were particularly flawed before this change. In general, the old code both over-counted and under-counted queries. It under-counted SQL usage for requests that were able to pull some data out of a warm cache before they did any SQL. Typically this would have bypassed the initial query to get UserProfile, so you will see several off-by-one fixes. The old code over-counted SQL usage to the extent that it's a rather extreme assumption that during an action itself, the entries that you put into the cache will get thrown away. And that's essentially what the prior code simulated. Now, it's still bad if an action keeps hitting the cache for no reason, but it's not as bad as hitting the database. There doesn't appear to be any evidence of us doing something silly like fetching the same data from the cache in a loop, but there are opportunities to prevent second or third round trips to the cache for the same object, if we can re-structure the code so that the same caller doesn't have two callees get the same data. Note that for invites, we have some cache hits that are due to the nature of how we serialize data to our queue processor--we generally just serialize ids, and then re-fetch objects when we pop them off the queue.

We assume our caller just edited a message.
Next, we will make sure we properly cached the messages. We still have
to do a query to hydrate recipient info, but we won't need to hit the
zerver_message table.

tests: Fix queries_captured to clear cache up front. Before this change we were clearing the cache on every SQL usage. The code to do this was added in February 2017 in 6db4879f9c9fd6941d3aa2af6138ea75aa6675a6. Now we clear the cache just one time, but before the action/request under test. Tests that want to count queries with a warm cache now specify keep_cache_warm=True. Those tests were particularly flawed before this change. In general, the old code both over-counted and under-counted queries. It under-counted SQL usage for requests that were able to pull some data out of a warm cache before they did any SQL. Typically this would have bypassed the initial query to get UserProfile, so you will see several off-by-one fixes. The old code over-counted SQL usage to the extent that it's a rather extreme assumption that during an action itself, the entries that you put into the cache will get thrown away. And that's essentially what the prior code simulated. Now, it's still bad if an action keeps hitting the cache for no reason, but it's not as bad as hitting the database. There doesn't appear to be any evidence of us doing something silly like fetching the same data from the cache in a loop, but there are opportunities to prevent second or third round trips to the cache for the same object, if we can re-structure the code so that the same caller doesn't have two callees get the same data. Note that for invites, we have some cache hits that are due to the nature of how we serialize data to our queue processor--we generally just serialize ids, and then re-fetch objects when we pop them off the queue.
