| Summary | 0005004: RTT measurements: handly_dummy is called twice per echo | ||||
| Description | in my branch 'improving-conversation' I implemented RTT measurements for gnunet-core. The measuring peer (A) sends a ping packet containing an identifier (timestamp) to an echo service on Peer B. When the echo is received the measured round-trip time is printed to stdout and the next ping is sent. A timeout functionality is implemented: if an echo response contains an unexpected identifier it is dropped and a warning is logged (gnunet-core.c:234). The bug is: handle_dummy is called twice for each received echo response. I verified with debug output that the ping packet is sent only once and that the echo service only sends one response. Maybe it's a simple logic bug, but I don't see it. | ||||
| Steps To Reproduce | Peer B: gnunet-core -e Peer A: gnunet-core -p <B's peerid> -r | ||||
| Tags | No tags attached. | ||||
| When I run the code, I get this: $ export GNUNET_FORCE_LOG="core;;;;DEBUG/" $ gnunet-core -p DSTJBRRKZ8TBW3FGK6B0M5QXWT9WYNZ45H5MCV4HY7ST64Q8T9F0 -r May 04 19:59:37-436465 core-api-11581 DEBUG Connecting to CORE service May 04 19:59:37-436520 core-api-11581 INFO (Re)connecting to CORE service May 04 19:59:37-437898 core-api-11581 DEBUG Connected to core service of peer `6YNB'.

| Haha, I'm stupid. Accidentally I was running two instances of 'gnunet-core -e', each one echoing the ping packets. Thanks for trying it out. | |
