[Jython-bugs] [issue2672] Integer formatting emits two minus signs with -2^31

[Jeff A. <re...@bu...>]

New submission from Jeff Allen <ja...@fa...>:

First observed by Helmut Niemann (thanks):

x = int(-(1<<31))
print ('%d' % x) # emits --2147483648

One also observe it as:

>>> int(-(1<<31)).__format__('d')
'--2147483648'

It's important that x be an int, not a long, which is in fact a clue to the work-around. Clearly this is a thinking error somewhere in int.__format__, so we should add a regression test in case it recurs.

[Jython-bugs] [issue2670] Non-public Java classes implementing collection types

[Jeff A. <re...@bu...>]

New submission from Jeff Allen <ja...@fa...>:

I noticed this in the investigation of #2662 and I'm spinning it off as a separate issue as I'm not really sure how to fix it. The obvious choice results in new failure in test_dict2java. So if that is the correct change, then the test is  wrong. I think it will be easier to see what to do after #2662 is fixed, which is more pressing.

I'm parking this so I don't have to fix it right away, but here are my observations.

There's a bit of PyJavaType.init() that goes:

        /*
         * PyReflected* can't call or access anything from non-public classes that aren't in
         * org.python.core
         */
        if (!Modifier.isPublic(forClass.getModifiers()) && !name.startsWith("org.python.core")
                && Options.respectJavaAccessibility) {
            handleSuperMethodArgCollisions(forClass);
            return;
        }

The problem with this is that for classes in core with names beginning Py, name is not set to the Java name but to a Python-like equivalent. Thus org.python.core.PyMapEntrySet has the name mapentryset by this point. The startsWith test returns false in these cases, so the if-body is executed even though the class is accessible to PyReflected* classes. Note also the return statement, which prevents subsequent processing in PyJavaType.init(), in particular it prevents the processing that would exposes the class as a Python-like collection.

The fix for this, so it works as apparently intended is to replace:
    name.startsWith("org.python.core")
with:
    forClass.getName().startsWith("org.python.core")

In that case, non-public classes from org.python.core (PyMapEntrySet and its like) will be subject to the processing in init() that applies to public classes from that Java package. Unfortunately, this causes a test failure in test.test_dict2java.py:

----------------------------------------------------------------------
Ran 4 tests in 0.047s

I believe this happens because because the classes that are return types from methods in javatests.Dict2JavaTest have a remove method that no longer returns a boolean result, because of the wrapping applied in PyJavaType.addCollectionProxies(Class<?>), making the Java API remove that returns boolean, look like the Python one, which returns None. See JavaProxySet.removeOverrideProxy

The dict of PyJavaType(PyMapEntrySet) is:
    {'__init__': <java constructor mapentryset 0x2>, 
     '__deepcopy__': <method '__deepcopy__' of 'mapentryset' objects>,
     'remove': <method 'remove' of 'mapentryset' objects>}

This is a much shorter list than results when the class is handled by the (possibly inappropriate) handleSuperMethodArgCollisions, and even the type of remove is different:

   {'getClass': <java function getClass 0x2>,
    'wait': <java function wait 0x3>,

[Jython-bugs] [issue2666] Imports in python from java do not work if there is a package the same name as class

[Jython-bugs] [issue2663] Remove dependency on javax.xml.bind.DatatypeConverter

[Jeff A. <re...@bu...>]

New submission from Jeff Allen <ja...@fa...>:

javax.xml.bind.DatatypeConverter is not present in Java 9. This prevents use with Java 9.

We are using it in core.ByteCodeLoader and compiler.Module in order to convert to/from Base64. However, we have our own code for that (in the codecs module), which I think could be applied here.

There is a java.util.Base64 class in Java 8, but it is not available in 7, which we intend to support a little while longer.

[Jython-bugs] [issue2662] IllegalAccessException accessing public abstract method via PyReflectedFunction

[Jeff A. <re...@bu...>]

New submission from Jeff Allen <ja...@fa...>:

I'm spinning this off from #2656 to cover the subset of those Java 9 problems with a common cause in PyReflectedFunction.

The codecs module provides an easy way to reproduce this (remote is just a batch file that runs jython withthe command line option for remote debugging):

PS jython-jvm9> .\remote -J--illegal-access=deny

java.lang.IllegalAccessException: java.lang.IllegalAccessException: class org.python.core.PyReflectedFunction cannot access class sun.nio.cs.GBK (in module java.base) because module java.base does not export sun.nio.cs to unnamed module @7ceb3185

For me the worrying thing is that newEncoder() is a *public* abstract method of CharSet, and yet we get this message on the grounds that the *implementation* sun.nio.cs.GBK is not exported. Obviously a factory that hands out instances of a private class that implements a public interface is a common pattern, and had better work in Jython.

My first idea is that we need to handle objects not according to their actual class, but according to some super class or interface that we are allowed to access.

[Jython-bugs] [issue2659] Determine console encoding without access violation (Java 9)

[Jeff A. <re...@bu...>]

New submission from Jeff Allen <ja...@fa...>:

Related to #2656: WARNING: Illegal reflective access by org.python.core.PySystemState (file:/C:/Jython/2.7.2a1/jython.jar) to method java.io.Console.encoding()

Unlike most of the other illegal accesses found by the test suite, this one will pop up from more-or-less any interactive use of Jython, hence the separate ticket. Also, we may wish to discuss the solution separately.


Problem:

Bytes written to sys.stdout/err emerge on the real (OS/shell) console untranslated, eventually via System.out/err. And the reverse is true on the way in. So Python needs to know the encoding, when the data is not ascii text, and expects to be told it via sys.stdout.encoding (etc.).

In the case of the JLine console, which replaces System.in/out/err, we take the bytes written by Python and *decode* them to characters, so JLine can encode them again the other side of its character editing. You can never have to many codecs.

When nothing else tells us the console encoding, we obtain it by a reflective call to the private java.io.Console.encoding(), which Java 9 doesn't like and threatens to disallow. If even that fails, we use the property file.encoding, however, this is dubious and generally misleading on Windows.


Solution proposed:

    do without the call that upsets Java 9,
    take a default supplied by the launcher (i.e. CPython), from interrogating sys.stdout.
    stop paying attention to file.encoding
    maybe use UTF-8 as a fixed last resort. (Or should it be None, meaning ASCII?)

I believe this makes the order of precedence (high to low):

    python.console.encoding (from the "post properties" supplied during initialisation)
    python.console.encoding (from system properties e.g. command line)
    python.console.encoding (from registry)
    PYTHONIOENCODING environment variable
    python.console.defaultencoding (from the launcher i.e. CPython) (NEW)
    UTF-8 (one, ASCII?) (NEW)

The last resort fixed encoding will only have effect if you don't use the launcher.

We can't simply specify python.console.encoding from the launcher because then this inference would take precedence over the registry and PYTHONIOENCODING.

[Jython-bugs] [issue2658] Update jython.org website

[Jeff A. <re...@bu...>]

New submission from Jeff Allen <ja...@fa...>:

The website is out of date and does not link the latest distribution or documentation. (See also #1590.) We need jython.org to present up-to-date information to support the 2.7.2 release, from the availability of the beta release. Even a simplified site is better if it is up-to-date.

We would like to move management of the website source to GitHub, which will allow us to share updating it.

See discussions on the jython-dev list (e.g. https://sourceforge.net/p/jython/mailman/message/36238580/). I'm raising an issue to signal that we regard this as part of the 2.7.2 release, as important as any software fix.

[Jython-bugs] [issue2656] Illegal reflective access warnings form Java 9

[Jeff A. <re...@bu...>]

New submission from Jeff Allen <ja...@fa...>:

On Java 9:

PS bugs> jython -J--illegal-access=warn
WARNING: Illegal reflective access by org.python.core.PySystemState (file:/C:/Jython/2.7.2a1/jython.jar) to method java.io.Console.encoding()

By 2.7.2 it would be nice not to be the poster-child for this new JDK feature:
https://docs.oracle.com/javase/9/migrate/#GUID-7BB28E4D-99B3-4078-BDC4-FC24180CE82B

The infamous one is fixed in jnr.posix (https://github.com/jnr/jnr-posix/issues/108), but others follow if one gives -J--illegal-access=warn. I feel we should at least fix the ones we're directly responsible for.

[Jython-bugs] [issue2654] Imported modules allow access to submodules

[James M. <re...@bu...>]

New submission from James Mudd <jam...@gm...>:

If you have a python module eg.

test_mod/
├── hello.py      <<<<< Contains only foo = 4
└── __init__.py   <<<<< Contains only _version__ = '1.1.1'

If you import this in cpython you will not have access to hello e.g.
>>> import test_mod
>>> dir(test_mod)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__']
>>> test_mod.hello
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'hello'

Which is correct because you didn't import test_mode.hello and the __init__.py doesn't import it.

In Jython (master)

>>> import test_mod
>>> dir(test_mod)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__'] <<<<< Looks good at this point
>>> test_mod.hello
<module 'test_mod.hello' from '/scratch/test_mod/hello.py'> <<<<< This is wrong shouldn't be able to see hello
>>> test_mod.hello.foo
4
>>> dir(test_mod)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__', 'hello'] <<<<< And now its added  to the module

I think this happens because of a change made to fix #2455 which means if you lookup an attribute on a Pyhton module and don't find it try to import it. The bug described in that ticket is when you have a mixed Python/Java package. However i'm not sure it should have been fixed and now the behaviour is wrong for Python. To fix this I think the support for the mixed Python/Java package needs to be removed which I don't see as an issue.

[Jython-bugs] [issue2653] Wrong error message when opening a busy file

[DanieleTrimarchi <re...@bu...>]

New submission from DanieleTrimarchi <dtr...@co...>:

This is a minor issue, but somehow annoying. 

Say there is a file that is busy because it is already opened in another application (for example: open a .csv file excel). 
When attempting to open this busy file in CPython2.7, we get a very specific error message: 

>python test.py
Traceback (most recent call last):
  File "test.py", line 3, in <module>
    f = open('testIO.csv','w')
IOError: [Errno 13] Permission denied: 'testIO.csv'
>>>

Now attempt the same in Jython 2.7.0 and will get a misleading error: 
Jython 2.7.0 (default:9987c746f838, Apr 29 2015, 02:25:11)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.8.0_131
Type "help", "copyright", "credits" or "license" for more information.
>>> f = open('testFile.csv','w')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IOError: [Errno 2] No such file or directory: 'testFile.csv'
>>>

Is there a chance to fix this behaviour and correcly report to the user what is going on?

Thanks, 
Daniele
