[Py4j-users] New intermediate release of Py4J

[Barthelemy D. <ba...@cs...>]

Hi,

I just built a new release of py4j that includes a few fixes:

1. long types are now correctly converted (issue #99). Please note that 
Python 3 merged int and long. This means that Py4J has to do all the 
inference work on the Java side for Python 3. In some corner cases, Py4J 
might not be able to call the method you want (e.g., you have 
method1(int) and method1(long) and you are calling from python 3 
method1(123). method1(int) will be called even though you may want 
method1(long) to be called. The only workaround I can think of is to 
create an adapter in Java and call this adapter).

2. decimals are now supported and correctly converted (issue #101)

3. plugged memory leak in GatewayServer when multiple python clients 
were connecting and disconnecting (java side, discussed on this mailing 
list last week)

4. gateway.close() (python side) now correctly sends a close signal to 
the java side (discovered while testing fix for #3)

5. by default, the python and java sides now try to connect to 127.0.0.1 
instead of localhost. It is always possible to specify an address when 
instantiating a JavaGateway and a GatewayServer.

The release is available in the current-release directory: 
https://github.com/bartdag/py4j/tree/master/current-release

It has been tested on python 2.7 and 3.2 and on Java 1.6. The full 0.8 
release will be tested on python 2.6, 2.7, 3.1, and 3.2.
