Introduce NEITHER_READ_NOR_WRITE in ctl.
...
This is slightly clearer in meaning. A function that is both READONLY() and
WRITEONLY() is in fact neither one.

Add "thread.idle" mallctl.
...
This can encapsulate various internal cleaning logic, and can be used to free up
resources before a long sleep.

Ehooks: Further optimize default merge case.

This avoids the cost of an iealloc in cases where the user uses the default
merge hook without using the default extent hooks.

Move extent2 -> extent.
...
Eventually, we may fully break off the extent module; but not for some time. If
it's going to live on in a non-transitory state, it might as well have the nicer
name.

Ecache: Should know its arena_ind.
...
What we call an arena_ind is really the index associated with some particular
set of ehooks; the arena is just the user-visible portion of that. Making this
explicit, and reframing checks in terms of that, makes the code simpler and
cleaner, and helps us avoid passing the arena itself all throughout extent code.
This lets us put back an arena-specific assert.

This lives within the ehooks_t now, so that callers don't need to know it.

Move relevant index into the ehooks_t itself.
...
It's always passed into the ehooks; keeping it colocated lets us avoid passing
the arena everywhere.

edata_cache: Remember the associated base_t.

This will save us some trouble down the line when we stop passing arena pointers
everywhere; we won't have to pass around a base_t pointer either.

Unify extent_alloc_wrapper with the other wrappers.
...
Previously, it was really more like extents_alloc (it looks in an ecache for an
extent to reuse as its primary allocation pathway). Make that pathway more
explciitly like extents_alloc, and rename extent_alloc_wrapper_hard accordingly.
2019-12-20 10:18:40 -08:00

Extent refactor: Introduce ecache module.

This will eventually completely wrap the eset, and handle concurrency,
allocation, and deallocation. For now, we only pull out the mutex from the
eset.

Arena: Loosen arena_may_have_muzzy restrictions.
...
If there are custom extent hooks, pages_can_purge_lazy is not necessarily the
right guard. We could check ehooks_are_default too, but the case where
purge_lazy is unsupported is rare and getting rarer. Just checking the decay
interval captures most of the benefit.
