I'm currently working on a new SAPI for web servers written in Go.
Many virtual machines, including Go VM, depend on signals using
SA_ONSTACK
. This flag allows a thread to define a new alternate signal stack. Many argue thatSA_ONSTACK
should be a default, but it's not the case (yet).This patch sets the
SA_ONSTACK
flag when PHP callssigaction()
.Python merged a similar patch (python/cpython#24730) in 2021 (Python 3.10+) for the same reasons, with no issues.
