Subject: [PATCH 0/3] Fake VFORK_DONE events on FreeBSD
Date: Tue, 28 Jun 2016 23:00:00 -0000 [thread overview]
Message-ID: <20160628230011.80849-1-jhb@FreeBSD.org> (raw)
The FreeBSD native targets do not report a VFORK_DONE event at
all currently. FreeBSD's ptrace doesn't currently report an event
when the vfork parent resumes, so this fixes the native targets to
report a fake event after a sleep similar to the approach used on
Linux. While here I noticed that I botched the 'detach_fork' support
in the original fork tracing patches, so I fixed that as well.
I am working on adding a new ptrace event to report a real vfork
done event to FreeBSD. Once that is merged to FreeBSD I will post
a patch for gdb to use that when available instead.
John Baldwin (3):
Honor detach-on-fork on FreeBSD.
Move fbsd_resume and related functions below fork following helper
code.
Fake VFORK_DONE events when following only the parent after a vfork.
