Created attachment 93741 [details] fix for ptrace attach race condition The attached patch fixes a race condition when attaching to newly created processes. The new method is using PTRACE_TRACEME on the child process. The context create notification is delayed until waitpid() reports that the context is stopped. Before this point no ptrace() calls should be made. A second issue was that when an attached process calls fork or clone the child stopped notification can come before the fork/clone notification. Prior to this change the stop notification was dropped which caused the state logic to be out of sync. With this patch the contextAdded event arrives after the return value of the command that created process. This seems incorrect, but the diagnostic tests seems to work.
