Subject: [PATCH 36/90] scratch space for FB-992: create benchmark for
 checkpointing

Note also the commented-out debug printf in checkpoint, there as a
reference. This is interesting because it turns out that MOST of checkpoint
writes is not actually writing new pages in most cases.

The actual "pages in WAL : pages in map" ratio is typically around 30:1
apparently. This would likely be different in cases where we were
updating existing data, though.

This is scratch space to prep for an actual work. The final
results will likely be different.

Subject: [PATCH 37/90] make test hit the lock harder

Discovered test was running slightly strange and spending an unreasonable
amount of time on rand.Intn(), possibly because we weren't caching the
value used as the loop condition. Tweaked that, also made the pool a
bit different. Now it takes ~50 seconds for benchtime 100x, and produces
a profile with a TON of time spent waiting on sleeps (expected) and
the condition variable for waiting on checkpoints (the thing we want
to measure, really).

Subject: [PATCH 38/90] refactor: removeTx responsible for getting/releasing
 its own lock

We change nothing substantive here, except that there's a window
between when a write transaction updates the root pages and when
it removes itself from the db tx list and possibly causes a checkpoint
where it's not holding the db lock.

The issue here is that we want to be able to *keep* the lock but
still return, so no one else can start transactions, but the specific
Rollback or Commit that removed the last outstanding transaction
doesn't block forever. This will, later, allow us to exercise
finer-grained control over when we allow transactions. This is
a separate commit so we can run the test suite against it, and
verify that this part in particular didn't break anything.

Subject: [PATCH 40/90] make db able to fail out if it can't checkpoint, fix
 silly wrong-units error

PageMap uses "WALID", which is a WAL page ID relative to the "base" ID of the
WAL, rather than the wal page count you'd get just reading the file. So everything
it reports has a fixed offset at any given time. I think this may be left
over from a point where there were partial checkpoints. Anyway, the net
outcome is that each new transaction was getting different page IDs, but
the actual WAL pages did not always reflect that. Each checkpoint increases
the offset. This might imply that we can start having problems after
4 billion pages written even if most of them were redundant?

Anyway, with that fixed, this seems to work. I think.

Subject: [PATCH 42/90] almost but not quite support async checkpoint

This gets us to being able to run reads during a checkpoint, but
now we have to wait for new reads to end before we can release
the write lock, etc.

This is actually slightly slower, but if we could get ONE more step,
we could allow new writes during that phase, to a different WAL,
if we had a different WAL to write to.

Subject: [PATCH 44/90] copy things rows after getting them and before their
 finishers during writes

When a qcx is a write, every Tx under it closes immediately, thus
invalidating all returned data. Thus, if you do a Not() inside a Store(),
you're doing a difference on an existence row and some other row
call... and both of those rows were run, individually, as separate
transactions that got invalidated the moment they were fetched. Oops.

Subject: [PATCH 45/90] test fixes and order of operations on changing
 db.PageMap

We need to update db.PageMap after we write the db, but before
we truncate the WAL, so new transactions don't pick up the old
PageMap and then get a truncated WAL.

Also, checkpoint should not abort if there's txs -- that's okay now.

Subject: [PATCH 46/90] fix locking and list management for afterCurrentTx

Two issues: First, there was a race condition because we were never
using the mutex for anything but the condvar broadcast, second, there
was no reason for the afterCurrentTx to need to maintain the list since
we already know where in the list we are when we are waking it up.

afterCurrentTx still wants to run with the db lock held, because
the degenerate case (no outstanding Tx) means that it will be running
with it held already. That's for another commit.

 happening

this is very approximate and may be a mess and may be unbounded, but
in practice i think it should be okay. if it's not we'll have an
adventure.

Subject: [PATCH 56/90] scale down worker pool when it's large

if we have more than twice our starting worker pool, and have had no
tasks when checking the queue for multiple rounds, send a job telling
the system to retire a worker. eventually we'll get down to about 2x
the starting pool size if we stay idle.

Subject: [PATCH 73/90] Fix RBF multi-level branch delete

This commit fixes a bug in RBF where deleting all the elements in
a bitmap that has a depth greater than 2 will cause the root bitmap
to be a branch page with a cell count of zero. This breaks an
assertion in `readBranchCell()` which causes a panic post-commit.

A new assertion has been added to prevent a branch page from being
written with a zero count in the future.

Subject: [PATCH 76/90] slightly better lock protection around bitDepth in view

There's a number of deeper issues here (the fragment is conjuring
up a Tx, for instance) but this helps.

Also use field.view() to get the view rather than accessing viewMap
directly without a lock. Also change field.cacheBitDepth to ratchet
upwards -- if we have multiple shards and some shards have lower
depths than others, we should use the highest as the cached value,
not the most recent.
