> The driver becomes unresponsive when two two exception are raised and not
> caught inside the Cassandra driver's response callback.
> how to reproduce:
> 1- setup a typical express (or total.js) project
> 2- add a simple route:
> {code:JavaScript}
> app.use('/test', test);
> {code}
> 3- code the route:
> {code:JavaScript}
> var cassandra = require('cassandra-driver');
> var contactPoints = ['cassandra-dev.nikoo.ir'];
> var driver = new cassandra.Client({
> contactPoints: contactPoints,
> keyspace: 'nikoomail',
> queryOptions: {prepare: true},
> socketOptions: {connectTimeout: 10000}
> });
> router.get('/', function(req, res, next) {
> console.log();
> console.log('-> Before executing the query');
> driver.execute('SELECT * FROM domain', [], function(err, result) {
> console.log('-> After executing the query');
> res.send('respond with a resource');
> throw new Error('Raising an exception here <--');
> });
> });
> {code}
> 4- add a global exception handler:
> {code:JavaScript}
> process.on('uncaughtException', function(err) {
> console.error(err);
> });
> {code}
> 5- run the project:
> npm start
> 6- navigate to http://localhost:300/test, notice the route works and the
> "respond with a resource" is seen
> 7- redo step (6),
> 8- for a third time repeat step (6) and notice the driver does not respond
> anymore and consequently nothing is received on the client side.
> Note: a sample project has been attached reproducing the error.
