Reported 2018-06-07 21:19:11 PDT
In order to get data on where malloc memory is being used, it would be useful to break down WebKit's malloc zone into smaller zones. One possibility is to make a different malloc zone for each ISOHeap.

I'm open to suggestions about whether any form of this should be landed behind an #ifdef.

Comment on attachment 342911 [details] Patch, not for landing View in context: https://bugs.webkit.org/attachment.cgi?id=342911&action=review I love this. But I’d like to see a version of this with fewer #if scattered around the code. > Source/JavaScriptCore/assembler/AssemblerBuffer.cpp:37 > + static NeverDestroyed<WTF::DebugHeap> heap = WTF::DebugHeap("WebKit AssemblerData"); Do we need to repeat the class name twice? Does this work? static NeverDestroyed<WTF::DebugHeap> heap { "WebKit AssemblerData" }; Or maybe the same thing but with two sets of braces? > Source/JavaScriptCore/assembler/AssemblerBuffer.h:88 > +#if ENABLE(MALLOC_HEAP_BREAKDOWN) > + m_buffer = static_cast<char*>(assemblerDataHeap().malloc(m_capacity)); > +#else > m_buffer = static_cast<char*>(fastMalloc(m_capacity)); > +#endif Can we instead up with some idiom where we always write the MALLOC_HEAP_BREAKDOWN version, but due to inlining it just compiles into a call to fastMalloc when MALLOC_HEAP_BREAKDOWN is not enabled? We’d just need assemblerDataHeap() to be an inline function returning an empty object with an inline malloc function, I think. > Source/JavaScriptCore/bytecode/AccessCase.h:84 > +#if ENABLE(MALLOC_HEAP_BREAKDOWN) > + WTF_MAKE_FAST_ALLOCATED_FROM_DEBUG_HEAP(AccessCase); > +#else > WTF_MAKE_FAST_ALLOCATED; > +#endif Same question. Can we avoid having the #if everywhere by having WTF_MAKE_FAST_ALLOCATED_FROM_DEBUG_HEAP expand to just WTF_MAKE_FAST_ALLOCATED when MALLOC_HEAP_BREAKDOWN is disabled?

I'll attempt to compact ValueProfile and ArrayProfile to make MetadataTable small, while I take a closer look into MetadataTable use. And I also want to know what whether this size of StringImpl is reasonable for Gmail, and what is UniqueArray here.

(In reply to Yusuke Suzuki from comment #14) BTW, I'm also running the script dumping all the allocations and annotating all of them with some meaningful stack trace entry. It seems that my script is too slow and it takes 32 more hours, but after that, we can get exact heap information too :)

Reviving Vector Malloc parameter now. I think this direction can, 1. offer the way to examine the content of Vectors more. The dumped result in Gmail says Vector takes much memory, but not sure what Vector is. In particular, we would like to report JSC::InstructionStream separately. 2. offer the way to make this patch works in a cleaner way. If it becomes cleaner enough, we could land it in upstream!

(In reply to Simon Fraser (smfr) from comment #28) > Bug 186698 has a patch to track vector allocation call sites. Nice! I'll also upload the patch with Malloc template parameter to Vector to handle more zones in a fine grained manner. And I introduced VectorMalloc / InstructionStreamMalloc and report InstructionStream memory separately. It turns out (as we all expected :P) InstructionStream (JS bytecode) in Gmail is large.

Gmail allocates massive # of closures. But # of Structure is a bit unexpected, 12.1MB is too large.

Isolated InferredValue Space_0x1142b0000 49.0M 3392K 3392K 0K 198 3152K 240K 8% 7 This is also too large. Can we reduce sizeof(InferredValue), or should we avoid creating this and embadding this data into FunctionExecutable / SymbolTable directly?

We call our system-malloc feature as DebugHeap (as it is defined in bmalloc), so we use this name. For this macro name, I'm ok for either using DEBUG_HEAP or MALLOC_ZONE. For now, I've just changed this to MALLOC_ZONE while keeping WTF::DebugHeap as DebugHeap since bmalloc is still using DebugHeap term.

I think this is not possible for now. To define ENABLE_MALLOC_HEAP_BREAKDOWN, we need to include BPlatform.h. But wtf/Platform.h is special header which is also used by sandbox preprocessing. So it should not include some random C headers. However, BPlatform.h includes some headers. So, at Platform.h, we do not have BENABLE_MALLOC_HEAP_BREAKDOWN.

Maybe WTF_MAKE_STRUCT_FAST_ALLOCATED_WITH_HEAP_IDENTIFIER(CodeBlockRareData) Sounds nice. Fixed. And we also change DECLARE_MALLOC_ZONE_ALLOCATOR => DECLARE_ALLOCATOR_WITH_HEAP_IDENTIFIER

I noted here. Sorry, I wasn't clear in my original message. I meant how to use it from C++, since you have to manually call *Allocator::malloc in a few places.
