Andrew McCreight faa1eb2316 Bug 1295688 - InfallibleAllocPolicy should crash on overflow. r=glandium
Code that uses InfallibleAllocPolicy presumably wants for operations
to always succeed. However, Vector and HashTable can end up detecting
that growing the data structure will fail due to integer overflow, and
then will call reportAllocOverflow() and fail. I think these cases
should crash.

In addition, pod_malloc and pod_realloc should crash rather than
returning NULL when they detect overflow.

This calls mozalloc_abort rather than MOZ_CRASH directly to avoid
circular #includes, because Assertions.h includes nsTraceRefcnt.h
which includes nscore.h which includes mozalloc.h.

Mike Hommey 63e7e7ede4 Bug 1280578 - Wrap HeapAlloc, HeapFree and HeapReAlloc on Windows. r=njn
The Win32 has non-malloc based heap allocation functions. They are not
widely used in the Gecko code base, but there are a few places that do
use them. They could be replaced with uses of malloc/free/realloc or
new/delete, but there is now an entirely separate problem that
requires wrapping those functions: the Rust static libraries are using
those functions to allocate memory.

Mike Hommey 8855262939 Bug 1269171 - Change how mozalloc.h is hooked in STL wrappers. r=froydnj
Since the introduction of the STL wrappers, they have included
mozalloc.h, and multiple times, we've hit header reentrancy problems,
and worked around them as best as we could.

Taking a step back, all mozalloc.h does is:
- declare moz_* allocator functions.
- define inline implementations of various operator new/delete variants.

The first only requires the functions to be declared before they are used,
so mozalloc.h only needs to be included before anything that would use
those functions.

The second doesn't actually require a specific order, as long as the
declaration for those functions comes before their use, and they are
either declared in <new> or implicitly by the C++ compiler.

So all in all, it doesn't matter that mozalloc.h is included before the
wrapped STL headers. What matters is that it's included when STL headers
are included. So arrange things such that mozalloc.h is included after
the first wrapped STL header is fully preprocessed (and all its includes
have been included).

Nicholas Nethercote eb9d46b90f Bug 1253512 (part 2) - Aggregate live blocks. r=erahm.
Due to the change in part 1, DMD now prints an entry for every live block,
which increases the output file size significantly in the default case. However,
a lot of those entries are identical and so can be aggregated via the existing
"num" property.

This patch does that, reducing output size by more than half.

Nicholas Nethercote 0f418f3874 Bug 1253512 (part 1) - Overhaul DMD's "sampling". r=erahm.
DMD currently uses a very hacky form of "sampling" by default to avoid
recording stack traces for all blocks. This makes DMD run faster than when it
records all stack traces.

This patch changes the sampling method used; in fact, it avoids "sampling" at
all. The existence of all heap blocks is now recorded exactly, but by default
we only record an allocation stack for each heap block if a Bernoulli trial
succeeds. This choice works well because getting the stack trace is ~100x
slower than recording the block's existence.

Overall, this approach is simpler and it also gives better output -- the choice
of which blocks to record allocation stacks for is mathematically sound, no
stack trace gets blamed for allocations it didn't do, and block counts and
sizes are now always exact.

Other specific things changed.

- All notion of sampling is removed from the various data structures.

- The --sample-below option is removed in favour of --stacks={partial,full}.

- The format of the JSON output file has changed.

- The names of various test files have changed to reflect concept changes.

Mike Hommey 9f2c4e94ba Bug 1209875 - Get rid of XULPPFLAGS. r=gps
The flags added in toolkit/locales/Makefile.in turn out not to be actually
used, so just remove that.

The remaining uses of XULPPFLAGS are to set debug flags depending on whether
MOZ_DEBUG is set or not. Just set a dedicated variable with the right value
from configure.

Nathan Froyd 5761751aa3 Bug 1207245 - part 1 - move RefCounted<T> to its own file
Various bits depend on RefPtr.h to provide RefCounted<T> and RefPtr<T>.
It will be easier to manage an automatic conversion from RefPtr<T> to
nsRefPtr<T> if we split out the dependency on RefCounted<T> first.

Mike Hommey 538706caba Bug 1203840 - Trigger dirty pages purge after CC. r=njn,r=smaug,r=mccr8
Jemalloc 4 purges dirty pages regularly during free() when the ratio of dirty
pages compared to active pages is higher than 1 << lg_dirty_mult.  We set
lg_dirty_mult in jemalloc_config to limit RSS usage, but it also has an impact
on performance.

So instead of enforcing a high ratio to force more pages being purged, we keep
jemalloc's default ratio of 8, and force a regular purge of all dirty pages,
after cycle collection.

Keeping jemalloc's default ratio avoids cycle-collection-triggered purge to
have to go through really all dirty pages when there are a lot, in which case
the normal jemalloc purge during free() will already have kicked in. It also
takes care of everything that doesn't run the cycle collector still having
a level of purge, like plugins in the plugin-container.

At the same time, since jemalloc_purge_freed_pages does nothing with jemalloc 4,
repurpose the MEMORY_FREE_PURGED_PAGES_MS telemetry probe to track the time
spent in this cycle-collector-triggered purge.

Now that we have moz.build, we can be guaranteed that any flags we add
in moz.build will be added after everything else has been setup.  So any
uses of MODULE_OPTIMIZE_FLAGS can be moved to moz.build's
CFLAGS/CXXFLAGS without any unusual repercussions.  We do have to verify
that MOZ_OPTIMIZE is in effect, though.

Andrew McCreight 6e608d39d9 Bug 1058178, part 2 - Implement address clamping analysis for DMD scan logs. r=njn
This adds a new option --clamp-contents to dmd.py. This replaces every value
contained in the memory contents in the log with a pointer to the start of a live
block, if the value is a pointer into the middle of that block. All other values
are replaced with 0. This conservative analysis makes it easier to determine
which blocks point to other blocks.

This implements a new "scan" mode for DMD that records the address

enables the low-level analysis of references from one block to
another, which can help leak investigations.
