If a caller starts the sampling heap profiler and takes a snapshot, and then deletes the snapshot before the sampling has completed, a use-after-free will occur on the StringsStorage pointer. The same issue applies for StartTrackingHeapObjects which shares the same StringsStorage object.

Abort incremental marking pulls in the requirement to also be able to abort on the embedder side. In practice, aborting is never really needed and the GC should just finalize the existing collection and do an atomic followup if exact marking information is required.

`SetBuildEmbedderGraphCallback`, unlike `SetWrapperClassInfoProvider`, assumes a monolithic embedder that can provide all necessary information. That is not the case for e.g. Node.js, which can e.g. provide multiple Node.js instances per V8 Isolate, as well as native addons that may allocate resources on their own.

That patch introduces EmbedderGraph interface that embedders can use to represent C++ objects that retain or are retained by V8 JS objects. The heap snapshot generator adds nodes and edges of the EmbedderGraph to the heap snapshot, allowing arbitrarily complex retaining paths that cross V8/Embedder boundary. The new functionality is enabled only if the embedder sets the BuildEmbedderGraph callback.

Revert of [profiler] Implement POC Sampling Heap Profiler (patchset #12 id:220001 of https://codereview.chromium.org/1555553002/ ) Reason for revert: The random nature of the tests caused the following buildbot to fail: https://build.chromium.org/p/client.v8/builders/V8%20Linux%20gcc%204.8/builds/4724/steps/Check/logs/stdio Original issue's description: > [profiler] Implement POC Sampling Heap Profiler > > This implements a proof-of-concept sampling based heap profiler inspired by > tcmalloc's heap profiler [1] and Go's mprof/memprofile [2]. > > The basic idea is the sample allocations using a randomized Poisson process. At > any point in time we can cheaply request the set of live sample objects that > should be a representative sample of heap. Samples include stack-traces from the > allocation sites, making this an effective tool for memory leak debugging. > > Unlike AllocationTracking, this is intended to be cheap and usable online in > production. > > The proof-of-concept is only sampling new-space allocations at this point. > Support for sampling paged space and native allocations is anticipated in the > future. > > [1] http://goog-perftools.sourceforge.net/doc/heap_profiler.html > [2] http://blog.golang.org/profiling-go-programs > > Committed: https://crrev.com/e5a9947811db9c9e23557dbad27f8b8a349b3262 > Cr-Commit-Position: refs/heads/master@{#33448} TBR=jochen@chromium.org,alph@chromium.org,hpayer@chromium.org,yangguo@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.

This implements a proof-of-concept sampling based heap profiler inspired by tcmalloc's heap profiler [1] and Go's mprof/memprofile [2]. The basic idea is the sample allocations using a randomized Poisson process. At any point in time we can cheaply request the set of live sample objects that should be a representative sample of heap. Samples include stack-traces from the allocation sites, making this an effective tool for memory leak debugging. Unlike AllocationTracking, this is intended to be cheap and usable online in production. The proof-of-concept is only sampling new-space allocations at this point. Support for sampling paged space and native allocations is anticipated in the future.

This tries to remove includes of "-inl.h" headers from normal ".h" headers, thereby reducing the chance of any cyclic dependencies and decreasing the average size of our compilation units. Note that this change still leaves 7 violations of that rule in the code. However there now is the "tools/check-inline-includes.sh" tool detecting such violations.

When compiling on a laptop I like to concatenate the small test files. This makes a big difference to compile times. These changes make that easier. R=ulan@chromium.org BUG= Review URL: https://codereview.chromium.org/1163803002 Cr-Commit-Position: refs/heads/master@{#28742}
