David Goldblatt 585f925055 Move cache index randomization out of extent.
This is logically at a higher level of the stack; extent should just allocate
things at the page-level; it shouldn't care exactly why the callers wants a
given number of pages.

David T. Goldblatt d936b46d3a Add malloc_conf_2_conf_harder
This comes in handy when you're just a user of a canary system who wants to
change settings set by the configuration system itself.

David Goldblatt 2e5899c129 Stats: Fix tcache_bytes reporting.
Previously, large allocations in tcaches would have their sizes reduced during
stats estimation.  Added a test, which fails before this change but passes now.

This fixes a bug introduced in 5934846612, which
was itself fixing a bug introduced in 9c0549007d.

David Goldblatt 0dcd576600 Edata cache: atomic fetch-add -> load-store.
The modifications to count are protected by a mutex; there's no need to use the
more costly version.
2020-03-12 11:58:09 -07:00
David Goldblatt 99b1291d17 Edata cache: add edata_cache_small_t.
This can be used to amortize the synchronization costs of edata_cache accesses.

David Goldblatt d701a085c2 Fast path: allow low-water mark changes.
This lets us put more allocations on an "almost as fast" path after a flush.
This results in around a 4% reduction in malloc cycles in prod workloads
(corresponding to about a 0.1% reduction in overall cycles).

David Goldblatt 397da03865 Cache bin: rewrite to track more state.
With this, we track all of the empty, full, and low water states together.  This
simplifies a lot of the tracking logic, since we now don't need the
cache_bin_info_t for state queries (except for some debugging).

David Goldblatt 44529da852 Cache-bin: Make flush modifications internal
I.e. the tcache code just calls a cache-bin function to finish flush (and move
pointers around, etc.).  It doesn't directly access the cache-bin's owned memory
any more.
2020-03-12 11:54:19 -07:00
David Goldblatt ff6acc6ed5 Cache bin: simplify names and argument ordering.
We always start with the cache bin, then its info (if necessary).
2020-03-12 11:54:19 -07:00
David Goldblatt e1dcc557d6 Cache bin: Only take the relevant cache_bin_info_t
Previously, we took an array of cache_bin_info_ts and an index, and dereferenced
ourselves.  But infos for other cache_bins aren't relevant to any particular
cache bin, so that should be the caller's job.

David Goldblatt 1b00d808d7 cache_bin: Don't let arena see empty position. 2020-03-12 11:54:19 -07:00
David Goldblatt d303f30796 cache_bin nflush -> n.
We're going to use it on the fill pathway as well.

David Goldblatt 74d36d78ef Cache bin: Make ncached_max a query on the info_t. 2020-03-12 11:54:19 -07:00
David Goldblatt b66c0973cc cache_bin: Don't allow direct internals access. 2020-03-12 11:54:19 -07:00
David Goldblatt 909c501b07 Cache_bin: Shouldn't know about tcache.
Instead, have it take the cache_bin_info_ts to use by pointer.  While we're
here, add a src file for the cache bin.

David Goldblatt 79f1ee2fc0 Move junking out of arena/tcache code.
This is debug only and we keep it off the fast path.  Moving it here simplifies
the internal logic.

This never tries to junk on regions that were shrunk via xallocx.  I think this
is fine for two reasons:
- The shrunk-with-xallocx case is rare.
- We don't always do that anyway before this diff (it depends on the opt
  settings and extent hooks in effect).

David T. Goldblatt 6c3491ad31 Tcache: Unify bin flush logic.
The small and large pathways share most of their logic, even if some of the
individual operations are different.  We pull out the common logic into a
force-inlined function, and then specialize twice, once for each value of
"small".

David T. Goldblatt 162c2bcf31 Background thread: take base as a parameter. 2020-02-18 11:22:09 -08:00
David T. Goldblatt 29436fa056 Break prof and tcache knowledge of b0. 2020-02-18 11:22:09 -08:00
David T. Goldblatt a0c1f4ac57 Rtree: take the base allocator as a parameter.
This facilitates better testing by avoiding mixing of the "real" base with the
base used by the rtree under test.
2020-02-18 11:22:09 -08:00
David T. Goldblatt 7013716aaa Emap: Take (and propagate) a zeroed parameter.
Rtree needs this, and we should really treat them similarly.

David T. Goldblatt 182192f83c Base: Pull into a single header. 2020-02-18 11:22:09 -08:00
David Goldblatt 7e6c8a7286 Emap: Standardize naming.
Namespace everything under emap_, always specify what it is we're looking up
(emap_lookup -> emap_edata_lookup), and use "ctx" over "info".
2020-02-17 10:50:51 -08:00
David Goldblatt ac50c1e44b Emap: Remove direct access to emap internals.
In the process, we do a few local cleanups and optimizations.  In particular,
the size safety check on tcache flush no longer does a redundant load.
2020-02-17 10:50:51 -08:00
David Goldblatt 06e42090f7 Make jemalloc.c use the emap interface.
While we're here, we'll also clean up some style nits.
