smembers return

[lulumahot]

Hello,
I need to request a redis db containing sets.
I think there is a problem with smembers and its return values :

std::vector<int> el; client.smembers(key), [&] (cpp_redis::reply& reply) { std::vector<cpp_redis::reply> rep = reply.as_array(); for (auto it = rep.begin(); it != rep.end(); it++){ el.push_back(std::stoi(it->as_string())); } }); client.commit();

I get pieces of the good answer and then segfault or memory error if i use this code. But if I put a sleep(1) before (or after) client.commit(); it's ok.

So I think the problem is the client is not reading returned values as far as they're sent. I can't use a sleep(1) because of my application.

Have you ever experienced that ? Thank you for your help.

Hi,

Unfortunately, I can't reproduce the bug on my machines.

Considering the fact that adding a sleep(1) seems to solve your problem, would it be possible that your program terminates while the different callbacks are executed?
In the examples, I used a while (not should_exit) loop: do you have a construct that allow you to avoid the destruction of the redis_client while there are still callback being processed?

If not, is there any way you could provide a valgrind report or gdb backtrace that could help me localize the problem? I'll keep trying to reproduce the error but it would help me a lot.

Thanks

I used a sync_commit and it solved it.
