1aabab5fdc Enforce TLS_MODEL attribute. 
Caught by @zoulasc in #1460.  The attribute needs to be added in the headers as
well.

f4d24f05e1 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.

020b5dc7ac Convert the format generator function to an annotated format function, 
so that the generated formats can be checked by the compiler.

d3d7a8ef09 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).

c2a3a7cd3f Fix test/unit/prof_log 
Compiler optimizations may produce traces more than expected.  Instead verify
the lower bound only.

93084cdc89 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.

9aab3f2be0 Add memory utilization analytics to mallctl 
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.

Qi Wang
978a7a21ae 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).

6fe11633b0 Fix the binshard unit test. 
The test attempts to trigger usage of multiple sharded bins, which percpu_arena
makes it less reliable.

788a657cee 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).

b804d0f019 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.

06f0850427 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.

atomics).

cbdb1807ce Stringify tls_callback linker directive 
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.

18450d0abe Guard libgcc unwind init with opt_prof.

some bootstrapping issues.

dca7060d5e Avoid redefining tsd_t. 
This fixes a build failure when integrating with FreeBSD's libc.  This
regression was introduced by d1e11d48d4
(Move tsd link and in_hook after tcache.).

9015deb126 Add build_doc by default. 
However, skip building the docs (and output warnings) if XML support is missing.
This allows `make install` to succeed w/o `make dist`.

e13400c919 Sanity check szind on tcache flush. 
This adds some overhead to the tcache flush path (which is one of the
popular paths).  Guard it behind a config option.

e3db480f6f 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
Qi Wang
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

d3145014a0 Explicitly use arena 0 in alignment and OOM tests. 
This helps us avoid issues with size based routing (i.e. the huge_threshold
feature).
