a011c4c22d cache_bin: Separate out local and remote accesses. 
This fixes an incorrect debug-mode assert:
- T1 starts an arena stats update and reads stack_head from another thread's
  cache bin, when that cache bin has 1 item in it.
- T2 allocates from that cache bin.  The cache_bin's stack_head now points to a
  NULL pointer, since the cache bin is empty.
- T1 Re-reads the cache_bin's stack_head to perform an assertion check (since it
  previously saw that the bin was empty, whatever stack_head points to should be
  non-NULL).

83cad746ae prof_log: cassert(config_prof) in public functions 
This lets the compiler infer that the code is dead in builds where profiling is
enabled, saving on space there.

f2e1a5be77 Do not fail on partial ctl path for ctl_nametomib() 
We do not fail on partial ctl path when the given `mib` array is
shorter than the given name, and we should keep the behavior the
same in the reverse case, which I feel is also the more natural way.

d9f7e6c668 hpdata: Add a test. 
We're about to make the functionality here more complicated; testing hpdata
directly (rather than relying on user's tests) will make debugging easier.

f7cf23aa4d psset: Relegate alloc/dalloc to test code. 
This is no longer part of the "core" functionality; we only need the stub
implementations as an end-to-end test of hpdata + psset interactions when
metadata is being modified.  Treat them accordingly.
 2020-12-07 06:21:08 -08:00

ca30b5db2b Introduce hpdata_t. 
Using an edata_t both for hugepages and the allocations within those hugepages
was convenient at first, but has outlived its usefulness.  Representing
hugepages explicitly, with their own data structure, will make future
development easier.

4ca3d91e96 Rename geom_grow -> exp_grow.

03a6047111 Edata cache small: rewrite. 
In previous designs, this was intended to be a sort of cache that couldn't fail.
In the current design, we want to use it just as a contention reduction
mechanism.  Rewrite it with those goals in mind.

bf72188f80 Allow opt.tcache_max to accept small size classes. 
Previously all the small size classes were cached.  However this has downsides
-- particularly when page size is greater than 4K (e.g. iOS), which will result
in much higher SMALL_MAXCLASS.

This change allows tcache_max to be set to lower values, to better control
resources taken by tcache.

d16849c91d psset: Do first-fit based on slab age. 
This functions more like the serial number strategy of the ecache and
hpa_central_t.  Longer-lived slabs are more likely to continue to live for
longer in the future.

This can be used to take pressure off a more centralized, worse-sharded
allocator without requiring a full break of the arena abstraction.

2a6ba121b5 PRNG test: cleanups. 
Since we no longer have both atomic and non-atomic variants, there's no reason

 2020-10-05 19:55:57 -07:00
David Goldblatt
9e6aa77ab9 PRNG: Remove atomic functionality. 
These had no uses and complicated the API.  As a rule we now expect to only use
thread-local randomization for contention-reduction reasons, so we only pay the
API costs and never get the functionality benefits.

018b162d67 Add psset: a set of pageslabs. 
This introduces a new sort of edata_t; a pageslab, and a set to manage them.
This is part of a series of a commits to implement a hugepage allocator; the
pageset will be per-arena, and track small page allocations requests within a
larger extent allocated from a centralized hugepage allocator.

b0ffa39cac Mallctl stress test: fix a type. 
The mallctlbymib_long helper was copy-pasted from mallctlbymib_short, and
incorrectly used its output variable (a char *) rather than the output variable
of the mallctl call it was using (a uint64_t), causing breakages when
sizeof(char *) differed from sizeof(uint64_t).

eaed1e39be Add sized-delete size-checking functionality. 
The existing checks are good at finding such issues (on tcache flush), but not
so good at pinpointing them.  Debug mode can find them, but sometimes debug mode
slows down a program so much that hard-to-hit bugs can take a long time to
crash.

This commit adds functionality to keep programs mostly on their fast paths,
while also checking every sized delete argument they get.

7e09a57b39 stress/sizes: Fix an off-by-one issue. 
Algorithmically, a size greater than 1024 ZB could access one-past-the-end of

ZB on all platforms we support (and we pick the arguments to this function to be
reasonable anyways), but it's not like there's any reason *not* to fix it,
either.

c9d56cddf2 Optimize meld in qr module 
The goal of `qr_meld()` is to change the following four fields
`(a->prev, a->prev->next, b->prev, b->prev->next)` from the values
`(a->prev, a, b->prev, b)` to `(b->prev, b, a->prev, a)`.

This commit changes

```
a->prev->next = b;
b->prev->next = a;
temp = a->prev;
a->prev = b->prev;
b->prev = temp;
```

to

```
temp = a->prev;
a->prev = b->prev;
b->prev = temp;
a->prev->next = a;
b->prev->next = b;
```

The benefit is that we can use `b->prev->next` for `temp`, and so
there's no need to pass in `a_type`.

The restriction is that `b` cannot be a `qr_next()` macro, so users
of `qr_meld()` must pay attention.  (Before this change, neither `a`
nor `b` could be a `qr_next()` macro.)

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.

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).

Previously, we took an array of cache_bin_info_ts and an index, and dereferenced

cache bin, so that should be the caller's job.

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).
