| Summary | 0001557: Send key fails in core | ||||
| Description | The testing testcases sometimes wait for a timeout or fail because of a failed set key operation (which then reschedules after a timeout). The testing framework operates as follows: 1) Start peers, get hello from each. 2) When asked to connect two peers, give the hello of one peer to the other. 2a) Wait for core to notify peers connected. Somehow, when this process happens core tries to transmit a set key request (which fails for some reason). And then the timeout is hit. This causes testcases on fast machines to take approximately the initial set key timeout before completing. For some reason on slow machines (specifically the sparcbot) an initial set key failure causes the peers to never connect, even on retries. Whether this is a related problem or a HELLO timeout or something else is unclear. | ||||

Reducing the initial timeout for set key operations seems to reduce test case failures, though it clearly doesn't solve the problem! |
|
|
Can be reproduced (even on fast machine) by running src/testing/test_testing_topology_clique a number of times. A delay can be observed *sometimes*, which with core debugging enabled reveals what's happening. |

I fixed a few issues in this area (down to util's connection API and back). So I suspect this is gone, but would be good if you could check. |
|
|
Seemingly fixed as of now. Set key failures are only happening when running thousands of nodes. So closing unless sparcbot or slower machines start failing testcases again. |
