[Qemu-devel] [PATCH v2 0/3] iotests: Fix test 039

[Max Reitz]

Test 039 used to fail because qemu-io -c abort may generate core dumps
even with ulimit -c 0 (and the output then contains "(core dumped)").
Fix this by adding a new qemu-io command "sigraise" which invokes
raise(). Using this command to raise SIGKILL for example does not result
in a core dump, but it still badly crashes qemu-io (as desired).

I am sending this series because we need all tests to work before adding
the check-block target to "make check" (which we will hopefully do
soon).


v2:
- Rewrote patch 1: Overloading "abort" may be somehow technically
  justifyable, but there is no point in grasping at straws when it is
  much easier to just introduce a new command. Therefore, in this
  version, "abort" is no longer overloaded and instead a new command,
  "sigraise", is added (I thought long and hard about that name; I
  thought "raise" to sound too unspecific, so this is what I came up
  with) [Markus]
- Patch 2: Fixed commit message (s/if it is aborted/when it is killed/)
  [Markus]
- Patch 3: %s/abort -S 9/sigraise 9/


git-backport-diff against v1:

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
