running a c++ test connects OK

ie,

#include <iostream>
#include "client/dbclient.h"

using namespace mongo;

void run() {
  DBClientConnection c;
  c.connect("localhost");
}

int main() {
  try {
    run();


g++ -g -O2 -fPIC testclient.cpp -I/usr/local/include/ 
    -I/usr/home/waitman/downloads/mongodb-src-r2.0.4/ 
    -L/usr/local/lib/ -lmongoclient -lboost_thread -lboost_filesystem

test client connects OK


# show log
Tue Apr 10 22:39:00 [initandlisten] connection accepted from 127.0.0.1:20154 #7
Tue Apr 10 22:39:00 [conn7] end connection 127.0.0.1:20154


but running the lua test hangs on connect (possibly forever but haven't waited that long). no errors/core etc 

require('mongo')
print ("1")
local db = assert(mongo.Connection.New())
print ("2")
assert(db:connect('127.0.0.1'))
print ("3")

never gets to 3. :(


Any help or suggestions much appreciated, thanks!

trying tests/connection.lua

added 2 lines -- print status:

function test_ReplicaSet()
    -- Create a Connection object
    local db = mongo.Connection.New()
    assertNotNil( db, 'unable to create mongo.Connection' )
        print ("connection object created")

    assert( db:connect(test_server), 'unable to forcefully connect to mongo instance' )
        print ("connected OK")

# tests/connection.lua 
==============================================================================
LUAMONGO_TEST_CONNECTION
==============================================================================
test_ReplicaSet: .connection object created

.....

sits forever (well longest i've waited is 20 minutes), no error or no 'connected OK'

hitting 'control-C' stops it (have to do it twice)

Can you let me know more about your setup? We're using this in production on an ubuntu server, so we obviously aren't seeing this issue. :)

[waitman]

sure, it's on a freebsd 10.0-CURRENT machine (amd64 smp out-of-order processors).

The C driver works fine (see example code) however the Lua wrapper hangs.
my OP shows the versions of os/software...

i will update things forward and give it another try. thanks!
