After testing it for a while it seems this might be connected to a
problem with closures and garbage collection. The network code works
fine most of the time, but then suddenly creating a new socket returns
an invalid one, thus the exception in the connect.
Creating a new socket involves the following sequence:
newTCP: family
"Create a socket and initialise it for TCP"
self initializeNetwork.
^[ super new initialize: TCPSocketType family: family ]
repeatWithGCIf: [ :socket | socket isValid not ]
and then on BlockContext/Closure
repeatWithGCIf: testBlock
| ans |
"run the receiver, and if testBlock returns true, garbage collect and
run the receiver again"
ans := self value.
(testBlock value: ans) ifTrue: [ Smalltalk garbageCollect. ans := self
value ].
^ans
Ideas anyone?
