[Qemu-devel] [PATCH v3 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).


v3:
- Patch 1:
  - s/allows to raise/allows raising/ [Eric]
  - %s/Unix signal/signal/g [Markus]
  - Use SIGTERM instead of SIGKILL in the example, and don't hardcode
    its value [Markus]
- Patch 3:
  - Fix commit message (should have been "sigraise 9" instead of
    "abort -S 9", and now it's "sigraise $(kill -l KILL)") [Fam]
  - As hinted above, use "sigraise $(kill -l KILL)" instead of
    hardcoding the value 9 for SIGKILL [Markus]


git-backport-diff against v2:

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
