Justine Tunney	dd8c4dbd7d	Write more tests for signal handling ... There's now a much stronger level of assurance that signaling on Windows will be atomic, low-latency, low tail latency, and shall never deadlock.	2024-09-21 05:24:56 -07:00
Justine Tunney	f68fc1f815	Put more thought into new signaling code	2024-09-19 20:21:33 -07:00
Justine Tunney	0d74673213	Introduce interprocess signaling on Windows ... This change gets rsync working without any warning or errors. On Windows we now create a bunch of C:\var\sig\x\y.pid shared memory files, so sigs can be delivered between processes. WinMain() creates this file when the process starts. If the program links signaling system calls then we make a thread at startup too, which allows asynchronous delivery each quantum and cancelation points can spot these signals potentially faster on wait See #1240	2024-09-19 03:02:13 -07:00
