Hi,
We are trying to upgrade to grpc 1.8.3 from 1.6 and seeing an issue with
one of our internal tests that works in 1.6 but fails in 1.8.3, where we're
seeing a bunch of these message:
E0108 23:10:24.009205427 68294 ev_epoll1_linux.cc:1098] assertion failed:
next_worker->state == KICKED
E0108 23:10:24.011880853 68330 ev_epoll1_linux.cc:1098] assertion failed:
next_worker->state == KICKED
E0108 23:10:24.011978910 68369 ev_epoll1_linux.cc:1098] assertion failed:
next_worker->state == KICKED
Looking at the code in branch 1.8.x [1], I see these two lines:
1098: GPR_ASSERT(next_worker->state == KICKED);
1099: SET_KICK_STATE(next_worker, KICKED);
I'm curious why the code is asserting X right before it's making X true? It
makes me look further and I see:
1044 } else if (next_worker->state == KICKED) {
...
goto done;
...
1063 } else if (next_worker->state == UNKICKED) {
...
goto done;
...
1072 } else if (next_worker->state == DESIGNATED_POLLER) {
...
goto done;
} else {
1098 GPR_ASSERT(next_worker->state == KICKED);
that seems to be a bug somewhere, since if we reach line 1098, then
next_worker->state cannot be KICKED?
Ideas?
Thanks!
