Hi,

Perhaps the main reason we cannot run important tests such as 041 in CI
is that when they care Unix sockets in $TEST_DIR, the path may become
too long to connect to them.

To get by this problem, this series lets the check script create a new
temporary directory (mktemp -d) and then makes the iotests use it for
all Unix sockets.


Max Reitz (23):
  iotests: Introduce $SOCK_DIR
  iotests.py: Store socket files in $SOCK_DIR
  iotests.py: Add @base_dir to FilePaths etc.
  iotests: Filter $SOCK_DIR
  iotests: Let common.nbd create socket in $SOCK_DIR
  iotests/083: Create socket in $SOCK_DIR
  iotests/140: Create socket in $SOCK_DIR
  iotests/143: Create socket in $SOCK_DIR
  iotests/147: Create socket in $SOCK_DIR
  iotests/181: Create socket in $SOCK_DIR
  iotests/182: Create socket in $SOCK_DIR
  iotests/183: Create socket in $SOCK_DIR
  iotests/192: Create socket in $SOCK_DIR
  iotests/194: Create sockets in $SOCK_DIR
  iotests/201: Create socket in $SOCK_DIR
  iotests/205: Create socket in $SOCK_DIR

  iotests/267: Create socket in $SOCK_DIR
  iotests: Drop TEST_DIR filter from _filter_nbd

Unix sockets generally have a maximum path length.  Depending on your
$TEST_DIR, it may be exceeded and then all tests that create and use
Unix sockets there may fail.

Circumvent this by adding a new scratch directory specifically for
Unix socket files.  It defaults to a temporary directory (mktemp -d)
that is completely removed after the iotests are done.

(By default, mktemp -d creates a /tmp/tmp.XXXXXXXXXX directory, which
should be short enough for our use cases.)

iotests.py itself does not store socket files, but it machine.py and
qtest.py do.  iotests.py needs to pass the respective path to them, and
they need to adhere to it.

Specifying this optional parameter allows creating temporary files in
other directories than the test_dir; for example in sock_dir.

Sockets should be placed into $SOCK_DIR instead of $TEST_DIR, so remove
the $TEST_DIR filter from _filter_nbd.

Should this use mkdir -p, in case two parallel processes compete with 
the same SOCK_DIR?

What if SOCK_DIR is set to something that is not a directory (say a 
file), at which point mkdir fails, but you don't seem to be catching 
that failure.

Otherwise looks good.

Do we want to output a literal 'SOCK_DIR' (every test that uses it has 
to update their expected output), or can we make this also output a 
literal 'TEST_DIR' (output is a bit more confusing on which dir to look 
in, but fewer files to touch)?  Your preference.

Agreed, it duplicates the setting inherited by sourcing common.nbd.

I'm assuming the series goes better through your iotests tree than my 
NBD tree.

Any reason these are still two iotests.FilePath(),

This goes away in 23, but this looks crazy.  Don't you really want the 
first line to replace $TEST_DIR with TEST_DIR (not $SOCK_DIR with 
TEST_DIR)?  Otherwise, bisection is likely to break until all the 
intermediate patches have made the conversion to stop using TEST_DIR.

I already gave R-b, but you'll need to fix this one.

Whoops - you have a bug in patch 4.  Once that is fixed, then deleting 
the line:

         -e "s#?socket=$TEST_DIR#?socket=TEST_DIR#g" \

here is appropriate.  So with that amendment to the series,

Thanks a lot for tackling this!

I gave it a try, and most tests work fine now indeed when I run them in
a directory with a veeeery long file name.

I still get an error with 028 though:

I would have used mkdir -p, but I saw we used this construct for
TEST_DIR, so I thought I‘d just go for the same.

Well, the same applies to TEST_DIR.  And technically, as long as we
don’t use mkdir -p for either, not catching the error at least helps
circumvent the potential race. O:-)

(I’ll convert both to mkdir -p with error handling.)

There’s another advantage to filtering it to be TEST_DIR, and that’s the
fact that if $TEST_DIR and $SOCK_DIR are the same, we will always
replace $SOCK_DIR by TEST_DIR.

But I still preferred filtering it to be SOCK_DIR, because that seemed
to me like we would have done it had we had a SOCK_DIR from the start.

The migration.sock FilePath line would have exceeded 80 characters, so I
would’ve had to wrap it.  Thus I decided I might as well make it a
FilePaths.

I didn’t dare touch the surrounding code, because that would have
required me to explain myself in the commit message. O:-)

Oops, yes.  I messed it up.  I only intended to add the SOCK_DIR
replacement line.

(Originally I had 23 merged into this one, and then I noticed it would
break bisection, so I tried to pull it out.  And failed, as you can see.)

I also think that using SOCK_DIR is the better choice. It's a little bit
more churn now, but in the long run, it will help to avoid confusion,
and I think that's more important.

Hm, I didn’t see any error for 028 or 055 myself.  028 makes use of
common.qemu, which uses FIFOs, and I thought there were exempt from this
problem.  And for 055 I have no idea.

Maybe just bugs in qemu? :-)

Yeah, maybe... anyway, both, 028 and 055, are not in the auto group, so
I think we simply could ignore these bugs for now.

I still don’t know about 055, but for 028 it looks like a race.

We have this:

> _send_qemu_cmd $h "drive_backup disk ${TEST_IMG}.copy" "(qemu)" >/dev/null
> _send_qemu_cmd $h "" "Formatting" | _filter_img_create

But it looks to me like the “Formatting” line comes earlier when the
path is longer.  No, I don’t know.

What I do know is that this looks wrong altogether.  Why would the
(qemu) prompt necessarily appear before the “Formatting” message?  I
think the drive-backup job creates the image before it is guaranteed to
yield.

So I think the solution is to s/(qemu)/Formatting/ in the expected
return value, replace the “"" "Formatting"” line by “"" "(qemu)"”, and
drop the “Formatting” output from the reference output.  (And add an
empty “(qemu)” line to the reference output.)
