[Qemu-devel] [PATCH v4 00/13] Support building with py2 or py3

[Qemu-devel] [PATCH v4 00/13] Support building with py2 or py3

[Daniel P. Berrange]

This is an update for my previously posted series:

 v2: https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg06528.html

This series enables some level of CI testing for py3 so that our CI jobs will
get coverage of both py2 and py3 builds to avoid bitrot.

I did a test travis build with py 3.0 and py 3.6 and got success:

  https://travis-ci.org/berrange/qemu/builds/328223261

The goal was to achieve the following

  ./configure --python=/usr/bin/python3
  make
  make check

This still requires passing python path to configure explicitly. A
further improvement would be for configure to automatically detect
a pythjon 3 binary and use it preferentially to python 2.

I have not attempted to fix/validate the block I/O tests. I would expect
them to be broken, but easily fixable with the similar kind of scope
changes as seen here. I felt it better to tackle that separately to
avoid this initial series getting too large.

Although the Python 2 EOL date is 2020, we already have distros which
are not shipping Python 2 by default (Fedora >= 26 has dropped Py2 from
the default install). Any new releases of long life and/or enterprise
distros may well not ship Python 2 given that it would go EOL long
before the EOL of the distro itself. IOW QEMU does have a fairly pressing
need to be able to support Python 3 for building.

A request for py3 is tracked here:

   https://bugs.launchpad.net/qemu/+bug/1708462

NB, Patch 10 here is not related to python 3 work - it was just a
temporary pre-requisite of pulling in the keycodemapdb update.

Changes since v3:

 - Remove space before '(' in print() function calls (Phillippe)
 - Force use of en_US.UTF-8 for QAPI code generation (Patchew)

Changes since v2:

 - Pull in fix for keycodemapdb
 - Enable testing with Travis
 - Enable testing with Fedora Docker images
 - Fix for sort ordering to fix 'make check-qapi-schema'
 - Fix for signrom data

Daniel P. Berrange (12):
  qapi: use items()/values() intead of iteritems()/itervalues()
  qapi: Use OrderedDict from standard library if available
  qapi: adapt to moved location of StringIO module in py3
  qapi: Adapt to moved location of 'maketrans' function in py3
  qapi: remove '-q' arg to diff when comparing QAPI output
  qapi: ensure stable sort ordering when checking QAPI entities
  qapi: force a UTF-8 locale for running Python
  scripts: ensure signrom treats data as bytes
  configure: allow use of python 3
  ui: update keycodemapdb to get py3 fixes
  travis: improve python version test coverage
  docker: change Fedora images to run with python3

Miika S (1):

[Qemu-devel] [PATCH v4 01/13] qapi: use items()/values() intead of iteritems()/itervalues()

[Daniel P. Berrange]

The iteritems()/itervalues() methods are gone in py3, but the
items()/values() methods are still around. The latter are less
efficient than the former in py2, but this has unmeasurably
small impact on QEMU build time, so taking portability over
efficiency is a net win.

[Qemu-devel] [PATCH v4 05/13] qapi: remove '-q' arg to diff when comparing QAPI output

[Daniel P. Berrange]

When the qapi schema tests fail they merely print that the expected
output didn't match the actual output. This is largely useless when
trying diagnose what went wrong. Removing the '-q' arg to diff
means that it is still silent on successful tests, but when it
fails we'll see details of the incorrect output.

ordering when calling the 'values()' method on a dict, compared
to python 2.x and later 3.x versions. Explicitly sort the items
to get a stable ordering.

[Qemu-devel] [PATCH v4 07/13] qapi: force a UTF-8 locale for running Python

[Daniel P. Berrange]

Python2 did not validate locale correctness when reading input data, so
would happily read UTF-8 data in non-UTF-8 locales. Python3 is strict so
if you try to read UTF-8 data in the C locale, it will raise an error
for any UTF-8 bytes that aren't representable in 7-bit ascii encoding.
e.g.

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 54: ordinal not in range(128)
Traceback (most recent call last):
  File "/tmp/qemu-test/src/scripts/qapi-commands.py", line 317, in <module>
    schema = QAPISchema(input_file)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 1468, in __init__
    parser = QAPISchemaParser(open(fname, 'r'))
  File "/tmp/qemu-test/src/scripts/qapi.py", line 301, in __init__
    previously_included)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 348, in _include
    exprs_include = QAPISchemaParser(fobj, previously_included, info)
  File "/tmp/qemu-test/src/scripts/qapi.py", line 271, in __init__
    self.src = fp.read()
  File "/usr/lib64/python3.5/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]

Many distros support a new C.UTF-8 locale that is like the C locale,
but with UTF-8 instead of 7-bit ASCII. That is not entirely portable
though, so this patch instead forces the en_US.UTF-8 locale, which
is pretty similar but more widely available.

We set LANG, rather than only LC_CTYPE, since generated source ought
to be independant of all of the user's locale settings.

This patch only forces UTF-8 for QAPI scripts, since that is the one
showing the immediate error under Python3 with C locale, but potentially
we ought to force this for all python scripts used in the build process.

[Qemu-devel] [PATCH v4 12/13] travis: improve python version test coverage

[Daniel P. Berrange]

Currently travis declares ancient python 2.4 is desired. Update that to
2.6 which is the oldest version any targetted distros still needs. If we
just list a python 3 version at the top level this will double the
number of travis jobs we run which is unreasonable.

So arbitrarily pick the clang test matrix entries to build with python
3.0 and 3.6, to extend coverage of python versions, without increasing
job count or build time.

Urgh, that sounds like a Python bug. The C locale is defined by POSIX to
be 8-bit clean (ie. a superset of ascii with 256 characters, not strict
ascii with only 128 characters and 128 bytes that form encoding errors).
 But that doesn't change the fact that we have to work around python's
braindead misinterpretation of reality.

s/independant/independent/

LANG is the lowest-priority setting - if the user has explicitly set
LC_CTYPE or LC_ALL, their settings override what is in LANG.

I'm worried that this is not reproducible in the face of a user that
explicitly sets different locale env-vars with higher priority than LANG.

But once we agree on the right override to stuff into PYTHON_UTF8, the
rest of the patch converting invocations to PYTHON_UTF8 makes sense.

Why are you bumping the submodule here and again in 11/13? Can those two
patches be squashed together?

FYI there is some background on this behaviour here:

 https://www.python.org/dev/peps/pep-0538/

NB that doc says the new C-is-UTF-8 assumpion is for Python 3.7 or later,
but Fedora backported it to F27's  Python 3.6 :-)

The failure can be seen on Fedora with 3.0 -> 3.5 only. (BTW you can
install many Python 3.x versions concurrently on Fedora which is handy
for testing)

You might remember a similar issue affecting libvirt-glib/libosinfo when
glib-mkenums was rewritten to use Python instead of Perl. For that I ended
up doing

   LC_ALL= LANG=C LC_CTYPE=en_US.UTF-8

Any thoughts on whether we should apply this more widely to our build
to make its output predictable regardless of user's locale ?

This patch is just temporarily pulled from another patch series, which
I expect to get merged before this one does.

QAPI changes stands out in the series' diffstat, so:
