Commented Issue: [BUG] Script execution blocks V8 script item finalization [86]
The V8 script item finalizer currently requires a V8 runtime lock. If the runtime is executing a long-running script, it can block the finalization thread and cause out-of-control memory consumption...

View ArticleCreated Issue: [BUG] Weak handle contexts are leaked during explicit disposal...
When cached V8 objects are explicitly disposed during V8 context destruction, the weak states of their handles must be cleared and the associated weak callback contexts deleted.

Hello infinitiesloop! You've discovered a very subtle bug that's unrelated to Issue #86. We're already testing fixes for both. Thank you! The excessive thread usage you're seeing is also unrelated, and...

I'm very interested in those fixes! I appreciate how active you guys are on this project still. We're using it for some compelling things :) It may be that my next move is to wait for your fixes and...

Here's the callstack with arguments. It's strange to me that NtWaitForSingleObject is called with all 0s. It's also strange to me that code_range_size is waiting on anything, because in the V8 code,...

Hi again, Hmm, that stack doesn't look correct at all. As you mentioned, v8::ResourceConstraints::code_range_size() doesn't call anything, and neither does the v8::ArrayBuffer::Contents constructor....

I don't think it is right, but I'm not sure how to get the correct symbols. Here's the 'noisy' output from windbg. I added a MS and Chrome symbol path:000007fe`fda210dc : 00000000`00000000...

V8 symbols are generated when you build ClearScript. If you obtained ClearScript via NuGet or another binary package, you could try searching for symbols somewhere within the package directory. By the...

I am using 5.4.2.1, from Nuget. It does not ship with the symbols. I've tried to build from source, but upon opening the solution, VS complains that it is using an older version of the VC++...

ClearScript's build procedure is outlined in the ReadMe. It currently requires Visual Studio 2013 (which includes the "v120" toolset), but the next point release, with the fixes mentioned above, will...

Got it! Here's a much better call stack. After a few thousand iterations in my system (which equates to a few thousand events being raised -- e.g. js callbacks being called), I end up with almost 200...

It appears that V8 maintains one "optimizing compiler thread" per isolate - an implementation detail beyond ClearScript's control. If your application uses the V8ScriptEngine constructor, it creates...

I have at most 10-15 scripts active at a time. For each script, I create a separate V8Runtime and create an engine off of that. I compile the script, too. So for each script I have a...

TL;DR: I may have identified my problem, which was my fault, but I'm not sure if it is expected behavior from ClearScript. Alright I figured out why my thread count was continuously rising. You saying...

Hi infinitiesloop, The Evaluate("[]") was being done on a NEW ScriptEngine rather than the Engine from the calling code. So the result was I was returning a js array created from one ScriptEngine back...
