I don't need main thread to be responsive, I want to read the data as soon as possible. It's possible to control the tracing from command line or another application, or I can use multiprocessing module to help.
How to do that? How to get data before trace has stopped?
It's probably possible to pipe the output of fbtracemgr to Python program, but I'm still interested how to do it with plain Python program.On Thu, Oct 24, 2013 at 12:39 PM, Pavel Cisar <pcisar@...> wrote:

it as it arrives. They do it in background thread, so main process is
always responsive and can end the trace session on your request (which
will also stop the background thread that was could be sleeping, waiting
in API call to engine). You can do the same in Python using FDB, but
it's much more code and more complicated than two-process solution
without threads.
