| * Cleaned up shard files (except VPTree)Douglas Rumbaugh2024-02-0728-1674/+859
| | | | | | | | | | | | Cleaned up shard implementations, fixed a few bugs, and set up some tests. There's still some work to be done in creating tests for the weighted sampling operations for the alias and aug btree shards.

| * FIFOScheduler: added automake wakeupDouglas Rumbaugh2024-01-221-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | Sometimes, when the max thread count is exceeded, it is possible for the scheduler to lock up. This is because the scheduler is only run when a new job is put into the queue, and so it is possible for a job to be blocked by thread limitations and be left sitting in the queue. If the main program is waiting on this job to finish before scheduling a new one, then the system deadlocks. I added a second background thread to the scheduler that wakes the scheduler up every 20us to resolve this and prevent these deadlocks.

| * Initial rough-out of internal statistics trackerDouglas Rumbaugh2024-01-198-36/+160
| | | | | | | | | | | | Need to figure out the best way to do the detailed tracking in a concurrent manner. I was thinking just an event log, with parsing routines for extracting statistics. But that'll be pretty slow.
| * Multiple concurrency bug fixesDouglas Rumbaugh2024-01-1714-185/+246
| | | | | | | | | | | | | | | | A poorly organized commit with fixes for a variety of bugs that were causing missing records. The core problems all appear to be fixed, though there is an outstanding problem with tombstones not being completely canceled. A very small number are appearing in the wrong order during the static structure test.

| * Initial integration of new buffering scheme into frameworkDouglas Rumbaugh2024-01-129-289/+158
| | | | | | | | | | It isn't working right now (lotsa test failures), but we're to the debugging phase now.
| * Initial pass at unit test refactoringDouglas Rumbaugh2024-01-1212-468/+757
| | | | | | | | | | | | Restructured unit tests to be a bit more modular. I have some further plans to expand on this, particular for the query tests (including both shard and framework level test functions that can be injected at will).
| * BufferView.h: Hopefully the last necessary tweak to the move semantics stuffDouglas Rumbaugh2024-01-121-24/+2
| | | | | | | | | | | | | | | | You can't move assign an std::Bind, but you can move construct it. So I had to disable the move assignment operator. This means that when you change the BufferView ownership over to, say, a QueryBufferState object, you need to do it by passing std::move(buffview) into a constructor call only--you cannot assign it.
| * InternalLevel update and testsDouglas Rumbaugh2024-01-114-51/+76
| | | | | | | | | | Plus some assorted fixes for move semantics stuff in BufferView that accompanied these changes.
| * Ported ISAMTree over to new buffer setupDouglas Rumbaugh2024-01-114-125/+137
| | | | | | | | | | I may still play with the shard from shards constructor, and queries need some work yet too.
| * BufferView: enforce move semanticsDouglas Rumbaugh2024-01-111-2/+19
| | | | | | | | | | | | Because a BufferView's lifetime is so tightly linked to the lifetime of regions of the buffer, it can't be copied without potentially breaking things.
