Signal SIGUSR2 not available on Windows

Open Tezar opened this issue 8 years ago • 3 comments

For development we use some boxes with Windows. Currently trying to include start agent on Windows produces self-explaining error

File "...\stackimpact\agent.py", line 113, in start register_signal(signal.SIGUSR2, _signal_handler) AttributeError: module 'signal' has no attribute 'SIGUSR2'

Is it safe to disable this signaling for Win? Unfortunately I am not sure for what is actually SIGUSR2 used in stackimpact so not providing PR.

The OS check was missing in the allocation profiler. I've just pushed a fix for it. Please get the latest agent.

FYI, SIGUSR2 is transparently used as a way to initiate allocation profiler on the main thread from timer threads.

Hi, thanksfor fast fix. Unfortunately it's still failing with same error. Problem occurs immediately when starting agent. Tried version 1.1.3 ca08a038a5a28a39b1828f6395877253e6d75dd3

That's right, a few more things were actually necessary. Please try the latest. Thanks.
