Bill Currie 0ebb0717b0 [zone] Add failing test cases ... The tests fail as they exercise how the cache *SHOULD* work rather than how it does now. The tests do currently pass for the pending work I've done on the cache system, but while working on it, I remembered why I reworked cache allocation... The essential problem is that sounds are loaded into the cache, which is fine for synchronous output targets, but has proven to be a minefield for asynchronous output targets (JACK, ALSA). The reason for the minefield is the hunk takes priority over the cache, and is free to move cache blocks around, and *even dispose of them entirely* in order to satisfy memory allocations from either end of the hunk. Doing this in an entirely single-threaded process (as DOS Quake was) is perfectly safe, as the users of the cache just reload the pointer each time, and bail if it's null (meaning the block has been freed), or even cause the data to be reloaded if possible (I'm a little fuzzy on the details for that as I didn't write that code). However, in multi-threaded code, especially real-time (JACK, possibly ALSA), it's a recipe for disaster. The 4cab5b90e6 commit was a (mostly) successful attempt to mitigate the problem by allocating the cache blocks from the high-hunk (thus minimizing any movement caused by low-hunk allocations), it resulted in cache allocates and regular high-hunk allocations somehow getting intertwined: while investigating just how much memory ad_tears needs (somewhere between 192MB and 256MB), I got "trashed sentinel" errors and upon investigation, I found what looks very suspiciously like audio data written across a hunk control block. I've decided that the cache allocation *algorithm* should be reverted to how it was originally designed by Id (details will remain "modern"), but while working on the tests, I remembered why I had done the changes in the first place (above story). Thus the work on reverting the cache allocation can't go in until I get sound memory management independent of the cache. The tests are going in now so I have a constant reminder :)		2022-06-03 12:52:59 +09:00
