Do a slightly better fix for r14329: don't call time() quite so much.  Also note the time(NULL) hack we wanted to do in the TODO.

Re-tune mempool parametes based on testing on peacetime: use smaller chuncks, free them a little more aggressively, and try very hard to concentrate allocations on fuller chunks.  Also, lots of new documentation.

809227a121 r14061@tombo: nickm | 2008-02-08 14:30:42 -0500
Add a couple of (currently disabled) strategies for trying to avoid using too much ram in memory pools: prefer putting new cells in almost-full chunks, and be willing to free the last empty chunk if we have not needed it for a while.  Also add better output to mp_pool_log_status to track how many mallocs a given memory pool strategy is saving us, so we can tune the mempool parameters.

Add code to shrink the cell memory pool by discarding empty chunks that have been empty for the last 60 seconds.  Also, instead of having test.c duplicate declarations for exposed functions, put them inside #ifdef foo_PRIVATE blocks in the headers.  This prevents bugs where test.c gets out of sync.

6589ea2a2f Fix a crash bug in cell queues: It is possible for a connection_write_to_buf to close the connection or otherwise unlink the circuit, which makes the circuit nonactive, which invalidates the pointer from the circuit to the next circuit on the active ring.
