Did anyone at Apple ever resolve why URL Access broke in 10.4 ???
It's all very nice to deprecate older technology, but you still have to
figure out what broke in case there's a more serious underlying bug in
10.4 . Some of my customers are reporting seemingly random stalls under
10.4 in Distributed Objects messaging that has worked for ages.
The symptom is that a listener thread receives some ICMP and tries to
pass it along to the main thread running the UI via DO. The main thread
freezes (spinning pizza). Pausing in the debugger shows the DO send
message code is looping and the message is never received. The problem
appears to be related to thread synchronization, and can be shifted or
reduced by applying NSLock. I haven't fully isolated it yet, but it
appears to involve multiple concurrent DO threads.
Perhaps URLAccess is just a canary indicating something else is broken.
