Callbacks never invoked with multiple pending queries about em-mongo

[merrells]

I think this might be intended behaviour... a connection only supports one outstanding request. My solution to this was to implement a connection pool.

Interesting... The code in connection.rb seems to imply that several requests could be pending at once. If it's a limitation in MongoDB, having a connection pool in em-mongo would probably be the right solution.

[merrells]

Even more interesting... I did try this initially, but found that response messages would trample over each other and then bson would throw an exception. I assumed from this that a connection could only be used for one outstanding request.

I am also having other problems... but can't pin it down to em-mongo yet.... sometimes I get an exception from bson.... and sometimes it does looks like all my connections hang.

I fixed the problems(s) I was having, and I might have fixed yours too. I also made it go a bit faster.

Nope, the spec I added still hangs after pulling your changes. Thanks for trying though.

[merrells]

I just committed another change that should have fixed your problem.

[jarib]

Awesome! I'll send Brendan a pull request (which now has your fixes + my spec) if that's ok with you.

[merrells]

sure

[merrells]

just fixed a bug in my patch
