Move extra size checks behind a config flag.
...
This will let us turn that flag into a generic "turn on runtime checks" flag
that guards other functionality we have planned.

remove compare and branch in fast path for c++ operator delete[]
...
Summary: sdallocx is checking a flag that will never be set (at least in the provided C++ destructor implementation). This branch will probably only rarely be mispredicted however it removes two instructions in sdallocx and one at the callsite (to zero out flags).

Ensure page alignment on extent_alloc.
...
This is discovered and suggested by @jasone in #1468 . When custom extent hooks
are in use, we should ensure page alignment on the extent alloc path, instead of
relying on the user hooks to do so.

The analytics tool is put under experimental.utilization namespace in
mallctl. Input is one pointer or an array of pointers and the output
is a list of memory utilization statistics.

Use iallocztm instead of ialloc in prof_log functions.
...
Explicitly use iallocztm for internal allocations. ialloc could trigger arena
creation, which may cause lock order reversal (narenas_mtx and log_mtx).

Fix the binshard unit test.

The test attempts to trigger usage of multiple sharded bins, which percpu_arena
makes it less reliable.

Allow low values of oversize_threshold to disable the feature.

We should allow a way to easily disable the feature (e.g. not reserving the
arena id at all).

Fallback to 32-bit when 8-bit atomics are missing for TSD.

When it happens, this might cause a slowdown on the fast path operations.
However such case is very rare.

Detect if 8-bit atomics are available.

In some rare cases (older compiler, e.g. gcc 4.2 w/ MIPS), 8-bit atomics might
be unavailable. Detect such cases so that we can workaround.

Proposed fix for #1444 - ensure that `tls_callback` in the `#pragma comment(linker)`directive gets the same prefix added as it does i the C declaration.

However, skip building the docs (and output warnings) if XML support is missing.
This allows `make install` to succeed w/o `make dist`.

Rename huge_threshold to oversize_threshold.

The keyword huge tend to remind people of huge pages which is not relevent to
the feature.
2019-01-25 13:15:45 -08:00
350809dc5d
Set huge_threshold to 8M by default.
...
This feature uses an dedicated arena to handle huge requests, which
significantly improves VM fragmentation. In production workload we tested it
often reduces VM size by >30%.
2019-01-24 13:29:23 -08:00

Explicitly use arena 0 in alignment and OOM tests.

feature).

Avoid creating bg thds for huge arena lone.
...
For low arena count settings, the huge threshold feature may trigger an unwanted
bg thd creation. Given that the huge arena does eager purging by default,
bypass bg thd creation when initializing the huge arena.

When custom extent_hooks or transparent huge pages are in use, the purging
semantics may change, which means we may not get zeroed pages on repopulating.
