I did this
Ran the example, passed URL to the fifo
I expected the following
Whenever the last transfer finishes, I'd expect to see
What I saw
Sometimes the message above is missing, and the mainloop keeps calling the timer after the last transfer is done.

In the good case, the end of the sequence is generally:
In the "bad" case, it's:
Call chain in the good case seems to be:
In the bad case:
i.e. the timer callback isn't called.
The text was updated successfully, but these errors were encountered:
I was able to reproduce the output by triggering a bad case (i.e. passing in an unresolvable hostname).
Looking further into the ephiperfifo source code, it appears that, unless
In real world scenarios, the documentation suggests CURLMOPT_TIMER_FUNCTION setting a non-repeating timer, so that the timer will not be triggered repeatedly when bad cases arise (where there's no need to reset a timer).
I ended up turning these interval settings to 0:
