Multi thread io_service::run() SET GET DEL #48

redboltz · 2017-10-25T01:48:56Z

I'd like to use redisclient on multi thread program. In the program, io_service::run() is called from each threads.

I got some unexpected behavior.

Here is the list of behavior I ovserved:

Got stucked. Log output is stopped.
Core dumped.

*** Error in `./a.out': double free or corruption (fasttop): 0x00007f4dd0002720 ***
[1]    17510 abort (core dumped)  ./a.out

Segmentation falult.

SET: OK[1]    17549 segmentation fault (core dumped)  ./a.out

Redis returns error.

SET: unique-redis-value
Invalid value from redis: unique-redis-value

I wrote the code that reproduces the behavior based on
https://github.com/nekipelov/redisclient/blob/master/examples/async_set_get.cpp

The code continues SET, GET, DEL, SET, GET, DEL, ...
When I run the executable file again and again, the behavior above is observed.

Can I send async command like redisClient.command("SET", ...) via the same connection from multiple threads?

The text was updated successfully, but these errors were encountered:

It might be related to #21.

I got more useful log for analyze using clang address sanitizer.

I guess that it is the following issue.
https://stackoverflow.com/questions/12794107/why-do-i-need-strand-per-connection-when-using-boostasio/12801042?noredirect=1#comment79777780_12801042

Should I serialize command sending to the redis connection?

And can I call multiple async command concurrently? Or I can call async command only from its callback function?

Boost.Asio async_write has the limitation:

This operation is implemented in terms of zero or more calls to the stream's
async_write_some function, and is known as a composed operation. 
The program must ensure that the stream performs no other write operations
(such as async_write, the stream's async_write_some function, or any other
composed operations that perform writes) until this operation completes.

http://www.boost.org/doc/libs/1_65_1/doc/html/boost_asio/reference/async_write/overload1.html

And one solution:

I found the answer for thread safety:

#34 (comment)

Is it thread safe? Can I use the RedisSyncClient with one global connection? Or should I go for RedisAsyncClient?

Is not thread-safe. Use locks, connection per thread or special thread.

I will use lock or one special thread for the redis connection.

So rest of my question is "can I call multiple async command concurrently? Or I can call async command only from its callback function?"

like this:

        // two async requests
        redisClient.command("SET",  {redisKey, redisValue},
                            std::bind(&Worker::onSet, this, std::placeholders::_1));
        redisClient.command("SET",  {redisKey, redisValue},
                            std::bind(&Worker::onSet, this, std::placeholders::_1));

Yes you can multiple async call. RedisClient serializes write operations in internal queue.

Thank you! It's easy to use :)
