Subject: [PATCH 0/3] Fix handling of pending fork events
Date: Wed, 24 Nov 2021 15:04:41 -0500	[thread overview]
Message-ID: <20211124200444.614978-1-simon.marchi@efficios.com> (raw)
In-Reply-To: <20211029203332.69894-1-simon.marchi@polymtl.ca>

This is v2 of:

  https://sourceware.org/pipermail/gdb-patches/2021-October/182922.html

Patch 2/3 is new, it factors out some code in the function, to keep the
following patch simple.

Changes in patch 3/3 (patch 2/2 in v1) are:

 - The test did fail on some machines (not my development machine
   apparently).  It is because I only handled pending statuses in
   lwp_info::status, in the linux-nat target.  There may also be some
   pending statuses in lwp_info::waitstatus, handle them too.
 - Rather than adding a target method to allow the core to detach
   pending fork children, make the targets (linux-nat and remote) peek
   in thread_info::pending_waitstatus to see if there is one there.

Simon Marchi (3):
  gdbserver: hide fork child threads from GDB
  gdb/linux-nat: factor ptrace-detach code to new detach_one_pid
    function
  gdb, gdbserver: detach fork child when detaching from fork parent
