Change all Python code to use print as a function.

This is necessary for Python 3 compatibility.

Done using:

  $ py=$( (g grep -l -E '^#!.*python';find -name '*.py' -printf '%P\n';) | \
    sort -u | grep -v README.sh4)
  $ futurize -w -f libfuturize.fixes.fix_print_with_import $py

From: Eduardo Habkost @ 2018-06-11 17:42 UTC (permalink / raw)
  To: Peter Maydell, qemu-devel; +Cc: Eduardo Habkost, Cleber Rosa

Make implicit relative imports explicit and add "from __future__ import
absolute_import" at the top of each relevant module.

This is necessary for Python 3 compatibility.

Done using:

  $ py=$( (g grep -l -E '^#!.*python';find -name '*.py' -printf '%P\n';) | \
    sort -u | grep -v README.sh4)
  $ futurize -w -f libfuturize.fixes.fix_absolute_import $py

Change obj.next() calls to next(obj).

This is necessary for Python 3 compatibility.

This is necessary for Python 3 compatibility.

All of the supported build platforms documented in qemu-doc.texi
should already support Python 2.7.

Removing support for Python 2.6 will allow us to remove some
compatibility modules we carry in the QEMU tree:

* scripts/argparse.py
* scripts/ordereddict.py

Python 2.6 is also not receiving bug fixes upstream and is not
supported by pylint, which makes it harder to keep the code
compatible with both Python 2 and Python 3.

Python 2.7 (the minimum Python version we require) already
provides the argparse module on the standard library.

-"""Command-line parsing library
-
-This module is an optparse-inspired command-line parsing library that:
-
-    - handles both optional and positional arguments
-    - produces highly informative usage messages
-    - supports parsers that dispatch to sub-parsers
-
-The following is a simple usage example that sums integers from the
-command-line and writes the result to a file::
-
-    parser = argparse.ArgumentParser(
-        description='sum the integers at the command line')
-    parser.add_argument(
-        'integers', metavar='int', nargs='+', type=int,
-        help='an integer to be summed')
-    parser.add_argument(
-        '--log', default=sys.stdout, type=argparse.FileType('w'),
-        help='the file where the sum should be written')
-    args = parser.parse_args()
-    args.log.write('%s' % sum(args.integers))
-    args.log.close()
-
-The module contains the following public classes:
-
-    - ArgumentParser -- The main entry point for command-line parsing. As the
-        example above shows, the add_argument() method is used to populate
-        the parser with actions for optional and positional arguments. Then
-        the parse_args() method is invoked to convert the args at the
-        command-line into an object with attributes.
-
-    - ArgumentError -- The exception raised by ArgumentParser objects when
-        there are errors with the parser's actions. Errors raised while
-        parsing the command-line are caught by ArgumentParser and emitted
-        as command-line messages.
-
-    - FileType -- A factory for defining types of files to be created. As the
-        example above shows, instances of FileType are typically passed as
-        the type= argument of add_argument() calls.
-
-    - Action -- The base class for parser actions. Typically actions are
-        selected by passing strings like 'store_true' or 'append_const' to
-        the action= argument of add_argument(). However, for greater
-        customization of ArgumentParser actions, subclasses of Action may
-        be defined and passed as the action= argument.
-
-    - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter,
-        ArgumentDefaultsHelpFormatter -- Formatter classes which
-        may be passed as the formatter_class= argument to the
-        ArgumentParser constructor. HelpFormatter is the default,
-        RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser
-        not to change the formatting for help text, and
-        ArgumentDefaultsHelpFormatter adds information about argument defaults
-        to the help.
-
-All other classes in this module are considered implementation details.
-(Also note that HelpFormatter and RawDescriptionHelpFormatter are only
-considered public as object names -- the API of the formatter objects is
-still considered an implementation detail.)

-    command line. The keyword arguments to the Action constructor are also
-    all attributes of Action instances.
-
-    Keyword Arguments:
-
-        - option_strings -- A list of command-line option strings which
-            should be associated with this action.
-
-        - dest -- The name of the attribute to hold the created object(s)
-
-        - nargs -- The number of command-line arguments that should be
-            consumed. By default, one argument will be consumed and a single
-            value will be produced.  Other values include:
-                - N (an integer) consumes N arguments (and produces a list)
-                - '?' consumes zero or one arguments
-                - '*' consumes zero or more arguments (and produces a list)
-                - '+' consumes one or more arguments (and produces a list)
-            Note that the difference between the default and nargs=1 is that
-            with the default, a single value will be produced, while with
-            nargs=1, a list containing a single value will be produced.
-
-        - const -- The value to be produced if the option is specified and the
-            option uses an action that takes no values.
-
-        - default -- The value to be produced if the option is not specified.
-
-        - type -- The type which the command-line arguments should be converted
-            to, should be one of 'string', 'int', 'float', 'complex' or a
-            callable object that accepts a single string argument. If None,
-            'string' is assumed.
-
-        - choices -- A container of values that should be allowed. If not None,
-            after a command-line argument has been converted to the appropriate
-            type, an exception will be raised if it is not a member of this
-            collection.
-
-        - required -- True if the action must always be specified at the
-            command line. This is only meaningful for optional command-line
-            arguments.
-
-        - help -- The help string describing the argument.
-
-        - metavar -- The name to be used for the option's argument with the

Hi; I noticed that running configure on my machine can now produce a
python traceback from docker.py:

make: Entering directory '/home/petmay01/linaro/qemu-for-merges/build/alldbg'
config-host.mak is out-of-date, running configure
Traceback (most recent call last):
  File "/home/petmay01/linaro/qemu-for-merges/tests/docker/docker.py",
line 29, in <module>
    from StringIO import StringIO
ImportError: No module named 'StringIO'
Install prefix    /usr/local
[etc]

I don't know if this is because of this change, but this is the
most recent change involving python...

The error also doesn't cause configure to fail, which is probably
a separate bug.

thanks

This seems to be introduced by:

commit 51a12b51fd3693a16eb73362713a98d467e15af7
Author: Alex Bennée <alex.bennee@linaro.org>
Date:   Wed Apr 4 14:24:39 2018 +0100

    configure: add test for docker availability

    This tests for a working docker installation without sudo and sets up
    config-host.mak accordingly. This will be useful from cross compiling
    things in the future.

    Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
    Reviewed-by: Richard Henderson <richard.henderson@linaro.org>

tests/docker/docker.py is still python2-only but ./configure is
trying to run it using $python (which can be Python 3).

Aha, yes -- I'd forgotten, but this config in my buildtest setup
is indeed configuring with --python=python3.
