basic_consume() throws an exception after 5 secs. #15

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Run the demo amqp_consumer.php
2. Wait 5 seconds.
3. The program crashes.

What is the expected output? What do you see instead?
I expect the consumer to idle indefinitely and output the data from the
message queue should amqp_publisher send something.
Intead I get the following error after 5 seconds:

PHP Fatal error:  Uncaught exception 'Exception' with message 'Error
reading data. Recevived 0 instead of expected 1 bytes' in
/usr/share/php/amqp_wire.inc:316

What version of the product are you using? On what operating system?
SVN downloaded on 4-23-2010

Please provide any additional information below.
If I quickly run the amqp_producer, the consumer will successfully get the
messages and output them.
It only fails if the producer hasn't sent anything for 5 seconds.

Increasing the value of read_write_timeout for the AMQPConnection constructor 
allows
the consumer to keep alive longer.  But does not seem to fix the root problem
(whatever it is, not sure).

On further inspection, it looks like it's mainly the buffer_read_timeout in
AMQPReader that is making AMQPReader->rawread() fail.

I'm not sure what to do here.  I really want to use the basic_consume 
functionality,
but it feels kind of wrong to stick the wait() function in a try block and just 
keep
ignoring exceptions.

This issue/patch solved the problem.  He just removed the buffer_read_timeout 
check.
