[Qemu-devel] [PATCH RFC v4 0/6] Update tests/qemu-iotests failing cases for the s390 platform

[Xiao Guang Chen]

v4:
1. Generate all patches based on the latest master branch.
2. Rearrange patches

v3: 
1. Fix a typo in v2.

v2:
1. Drop the patches for test 039 for it has been fixed in upstream.
2. Integrate patches for test 071, 067 and 087.
3. Keep the other patches.

v1:
1. updated the test suite to be default-machine-type-aware, from the previous platform-aware
2. created a new patch "qemu-iotests: run qemu with -nodefaults" to counterpart the impact from the commit:
	c88930a6866e74953e931ae749781e98e486e5c8
	qemu-char: Permit only a single "stdio" character device

    When more than one is used, the terminal settings aren't restored
    correctly on exit.  Fixable.  However, such usage makes no sense,
    because the users race for input, so outlaw it instead.

    If you want to connect multiple things to stdio, use the mux
    chardev.
3. updated all the checking of platform name to the current machine name

[Qemu-devel] [PATCH RFC v4 1/6] qemu-iotests: run qemu with -nodefaults

[Xiao Guang Chen]

This patch fixes an io test suite issue that was introduced with the
commit c88930a6866e74953e931ae749781e98e486e5c8 'qemu-char: Permit only
a single "stdio" character device'. The option supresses the creation of
default devices.

[Qemu-devel] [PATCH RFC v4 2/6] qemu-iotests: qemu machine type support

[Xiao Guang Chen]

From: Mao Chuan Li <maochuan@linux.vnet.ibm.com>

This patch adds qemu machine type support to the io test suite. Based on
the qemu default machine type the reference output file can now vary
from the default to a machine specific output file if necessary. That
shall allow all platforms to use this test suite.

[Qemu-devel] [PATCH RFC v4 3/6] qemu-iotests: fix tests 067, 071 and 087

[Xiao Guang Chen]

Update the output files for test case 067, 071 and 087 because qemu option
-nodefaults was used to start a guest so there are no default floppy and
cdrom for guests any more.
Use virtio-blk instead of virtio-blk-pci as the device driver for test case
067. For virtio-blk-pci is the same with virtio-blk as device driver but
other platform such as s390 may not recognize the virtio-blk-pci.

[Qemu-devel] [PATCH RFC v4 4/6] qemu-iotests: s390x: fix test 041

[Xiao Guang Chen]

From: Mao Chuan Li <maochuan@linux.vnet.ibm.com>

There is no such device 'ide-cd' defined on the s390 platform, so
test_medium_not_found() test is skipped.

[Qemu-devel] [PATCH RFC v4 5/6] qemu-iotests: s390x: fix test 051

[Xiao Guang Chen]

From: Mao Chuan Li <maochuan@linux.vnet.ibm.com>

The tests for device type "ide_cd" are skipped for the s390 platform.
The default device id of hard disk on the s390 platform differs to that
of the x86 platform. A new variable device_id is defined and "virtio0"
set for the s390 platform. A s390 platform specific output file is also
needed.

[Qemu-devel] [PATCH RFC v4 6/6] qemu-iotests: s390x: fix test 055

[Xiao Guang Chen]

There is no such device 'ide-cd' defined on the s390 platform, so
test_medium_not_found() test is skipped.

I believe the reason to quote ${QEMU} was allow paths containing whitespaces.
Why not leave the quotes unchanged and add $QEMU_OPTIONS here?

I think the reason is to keep a consistent calling style with other qemu 
facilities such as: QEMU_IO.

Maybe this should be [ -f "$reference_machine" ]. I guess spaces in the 
directory name will break the qemu-iotests anyway, but there's no reason 
not to use quotes here.

Interesting that "-machine ?" works. I would have expected it needed to 
be "-machine \?".

Apparently bash does not replace wildcard characters if there is no 
match (in contrast, zsh errors out in that case). Therefore, this only 
works as long as there is no single-character-named file in the 
directory where "check" is executed (test: "touch i; ./check").

Therefore, I think this needs to be "-machine \?" after all.

I think this patch and patch 3 are fine, but there is no reason not to 
squash 3 into 1. The reason I'm suggesting that once again is that it 
prevents tests 067, 071, and 087 from breaking (which would be a really 
nice thing).

So if you decide not to squash them I'll probably give an Reviewed-by 
anyway, but you really should consider doing it.

First: This patch contains lines which are too long to be sent via email 
(they are broken up and thus the patch needs manual fixup by the 
reviewers). If you could specify a public repository where we could pull 
from, that may be helpful to the reviewers.

Second: I'm not sure whether s390-virtio should be the special case 
here. Maybe "pc" is the platform that is actually special because it 
contains a floppy drive, an IDE CD drive and so on. So while this patch 
is (nearly?) correct, it may make more sense to move 051.out to 
051.pc.out and modify the current 051.out to be what is 
051.s390-virtio.out in this patch.

In the same way, maybe all the conditionals in this series (not just 
this patch) which check whether the machine type is s390-virtio should 
maybe instead check whether the machine type is not pc.

However, the problem with the pc machine type is that 
QEMU_DEFAULT_MACHINE will be version-dependent (currently, it's 
pc-i440fx-2.3), so that would require a workaround.

Can't we get rid of these warnings somehow? If nothing else works, 
filter them out?

As I said in my reply to patch 4, please use spaces instead of tabs. 
Also, as said in my reply to patch 5, maybe the conditions should be 
iotests.qemu_default_machine != 'pc' or something similar.

But the latter is up to you, so with the tabs replaced by eight spaces each:

Or, since the script explicitly required bash, use a bashism:

Correct, you need quoting here to avoid accidental globbing.

bash and zsh chose different defaults, but both shells are configurable
in the other direction (you can tell zsh to turn off warnings; and
here's how to make bash balk at an unsuccessful glob: shopt -s failglob

I can not find a public repository. Do you have other options?
Or I manually split the long lines into small ones only for review. But 
it will not work if you apply the patch.

OK.

OK.

When we run the qemu-system-x86_64 -machine ? we will get the following 
output:
Supported machines are:
pc                   Standard PC (i440FX + PIIX, 1996) (alias of 
pc-i440fx-2.3)
pc-i440fx-2.3        Standard PC (i440FX + PIIX, 1996) (default)
pc-i440fx-2.2        Standard PC (i440FX + PIIX, 1996)
pc-i440fx-2.1        Standard PC (i440FX + PIIX, 1996)
......

We can get the default machine:pc-i440fx-2.3 and the alias of the 
default machine:pc.
If the default machine has an alias then we use the alias otherwise we 
use the default machine.

*qemu/tests/qemu-iotests/common.config:*
/default_machine=$($QEMU -machine \? | awk '/(default)/{print $1}')//
//default_alias_machine=$($QEMU -machine \? |\//
//    awk -v var_default_machine=$default_machine\)\//
//    '{if 
($(NF-2)=="(alias"&&$(NF-1)=="of"&&$(NF)==var_default_machine){print 
$1}}')//
//if [ ! -z "$default_alias_machine" ]//; then
//    default_machine="$default_alias_machine"//
fi
//export QEMU_DEFAULT_MACHINE=$default_machine/

How about this change?

Well, in that case, better leave it as it is; I have a script for 
"fixing" the patch, so as far as I'm concerned, it's fine.
