New issue 3735 by [email protected]: Debugging freezes on evaluation of
an object
https://code.google.com/p/v8/issues/detail?id=3735
Steps to reproduce:
1) Please run the attached file in node in debugging mode:
node debug main.js
It might be necessary to generate the required keys and certificate in
advance via:
openssl genrsa -out agent-key.pem 1024
openssl req -new -key agent-key.pem -out agent-csr.pem
openssl x509 -req -in agent-csr.pem -signkey agent-key.pem -out
agent-cert.pem
2) Submit a breakpoint on line 16:
debug> sb(16)
3) Continue
debug> cont
and navigate to https://localhost:44301/ in the browser.
4) When suspended, try to get variable values:
debug> repl
> req._readableState
- this evaluates correctly and prints out the object properties and
their values
> req.connection._buffer
- we get no answer and node process starts to consume 100% CPU.
This issue was discovered in an IDE, which uses V8 debugging protocol.
As a response of the lookup command to "connection", we get it's buffer
property as:
{"name":"_buffer","propertyType":1,"ref":147}
When we issue lookup command for "_buffer", we get no answer and node
process starts to consume 100% CPU. The lookup command request looks like:
{"arguments":{"handles":[147],"includeSource":false},"type":"request","seq":79,"command":"lookup"}
