Tya v0.60 Release Notes

v0.60 makes Tya concurrency match the class-style direction of the standard library while starting the runtime path toward C10K workloads.

Highlights

• channel.Channel(capacity) replaces channel.Channel.new(capacity).
• Channel operations are instance methods: send, receive, receive_timeout, close, and closed?.
• Task cancellation is instance-based: t.cancel() and t.cancelled?().
• Synchronization primitives are classes: sync.Mutex, sync.AtomicInteger, and sync.WaitGroup.
• select is now a language statement for channel receive, send, timeout, and default arms.
• spawn tasks are scheduled as cooperative lightweight runtime tasks rather than one OS thread per task.

Breaking Changes

The old helper APIs are removed. Use the instance-method forms instead.

channel.Channel.new(10)        # removed
channel.Channel.send(c, value) # removed
channel.Channel.select([...])  # removed
sync.Sync.mutex()              # removed
task.Task.cancel(t)            # removed

Removed helper calls report TYA-E0820.

Verification

The release includes script coverage for:

• class-style channel, task, mutex, atomic integer, and wait group APIs;
• select receive, send, and default arms;
• removed helper diagnostics;
• 10,000 blocked channel receiver tasks without creating 10,000 OS threads.
