TimeStamp::ProcessCreations()'s aIsInconsistent outparam is ignored by the
majority of its caller. This patch makes it optional. Notably, this makes
ProcessCreation() easier to use in a constructor's initializer list.
The parent and content processes can have different temp directories
when sandboxing is enabled, so the process that creates the file for a
heap snapshot must also determine the snapshot ID.

This change avoids lots of false positives for Coverity's CHECKED_RETURN
warning, caused by NS_WARN_IF's current use in both statement-style and
expression-style.
In the case where the code within the NS_WARN_IF has side-effects, I made the
following change.
> NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
> -->
> Unused << NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
In the case where the code within the NS_WARN_IF lacks side-effects, I made the
following change.
> NS_WARN_IF(!condWithoutSideEffects);
> -->
> NS_WARNING_ASSERTION(condWithoutSideEffects, "msg");
This has two improvements.
- The condition is not evaluated in non-debug builds.
- The sense of the condition is inverted to the familiar "this condition should
be true" sense used in assertions.
A common variation on the side-effect-free case is the following.
> nsresult rv = Fn();
> NS_WARN_IF_(NS_FAILED(rv));
> -->
> DebugOnly<nsresult rv> = Fn();
> NS_WARNING_ASSERTION(NS_SUCCEEDED(rv), "Fn failed");
There can be multiple compartments within the same zone, only one of which is a
debuggee. In this scenario, CCWs from other compartments into the debuggee
compartment should be traced and treated as roots. Therefore, dealing with CCWs
at the JS::Zone level is incorrect, and this patch changes the granularity level
to JSCompartments. If you look at the callers and uses of the function, it makes
much more sense now.
Additionally, it renames `JS_TraceIncomingCCWs` to `JS::TraceIncomingCCWs`.
This commit adds the `computeShortestPaths` method to the `HeapSnapshot` webidl
interface. It implements this new method on the
`mozilla::devtools::HeapSnapshot` class.
This commit implements the HeapSnapshot.describeNode method which allows chrome
JS code to request a description of a given node as specified by our existing
"breakdown" language. This description can be used to generate a human-readable
label for the node.
This commit adds the DominatorTree.webidl interface, which is only exposed to
chrome JS. The interface is implemented by mozilla::devtools::DominatorTree,
which is a thin wrapper around JS::ubi::DominatorTree. This does not expose any
methods on the DominatorTree interface, those will come as follow up changesets.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This changeset replaces all of the
// char16_t[]
optional bytes someProperty = 1;
one- and two-byte string properties in the CoreDump.proto protobuf definition
file with:
oneof {
// char16_t[]
bytes someProperty = 1;
uint64 somePropertyRef = 2;
}
The first time the N^th unique string is serialized, then someProperty is used
and the full string is serialized in the protobuf message. All following times
that string is serialized, somePropertyRef is used and its value is N.
Among the other things, this also changes JS::ubi::Edge::name from a raw pointer
with commented rules about who does or doesn't own and should and shouldn't free
the raw pointer to a UniquePtr that enforces those rules rather than relying on
developers reading and obeying the rules in the comments.
This enables the use of ubi::Node in situations where a JSContext* is not
available, and paves the way for debugging utilities to dump shortest paths from
GC roots to a given ubi::Node that can be used while paused in a debugger.
