Mike Hommey 97f635df6b Bug 1303232 - Use per-process reduced thread-ids when munging logalloc logs. r=njn
Bug 1300948 added thread-ids to logalloc logs, and logalloc_munge.py was
munging them all as if they were all under the same namespace. But when
filtering munged logs to only contain logs from a given process,
thread-ids then don't necessarily start from 1, which would be the
desired outcome.

So use a different pool of thread-ids for each process.

Andrew McCreight 5772f60634 Bug 1295695 - Add maybe_pod_* methods to InfallibleAllocPolicy. r=glandium
Bug 1207519 added maybe_pod_* methods to the allocation policy
classes, but did not add them to InfallibleAllocPolicy.

I think the idea of these methods is that the callers are explicitly
opting into fallible behavior, so they will deal with any errors that
occur. For instance, in js::HashTable, this is used to try to shrink
the hash table when there are a lot of unused entries. If the shrink
fails, it just continues to use the existing block of memory.

However, having fallible methods in a supposedly infallible class is
weird, so for now, just use the infallible version.

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.
