[issue28603] traceback module can't format/print unhashable exceptions
Andreas Stührk added the comment: It was reported as bug to a project that uses the traceback module (https://github.com/bpython/bpython/issues/651). Parsley (https://pypi.python.org/pypi/Parsley) is at least one library that uses unhashable exceptions, although I guess it's by accident: it defines __eq__, but not __hash__ and that makes the exception unhashable under Python 3. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28603> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue28603] traceback module can't format/print unhashable exceptions
New submission from Andreas Stührk: The traceback module tries to handle loops caused by an exception's __cause__ or __context__ attributes when printing tracebacks. To do so, it adds already seen exceptions to a set. Unfortunately, it doesn't handle unhashable exceptions: >>> class E(Exception): __hash__ = None ... >>> traceback.print_exception(E, E(), None) Traceback (most recent call last): File "", line 1, in File "/usr/lib/python3.5/traceback.py", line 100, in print_exception type(value), value, tb, limit=limit).format(chain=chain): File "/usr/lib/python3.5/traceback.py", line 439, in __init__ _seen.add(exc_value) TypeError: unhashable type: 'E' CPython's internal exception printing pretty much does the same, except it ignores any exception while operating on the seen set (see https://hg.python.org/cpython/file/8ee4ed577c03/Python/pythonrun.c#l813 ff). Attached is a patch that makes the traceback module ignore TypeErrors while operating on the seen set. It also adds a (minimal) test. -- components: Library (Lib) files: unhashable_exceptions.diff keywords: patch messages: 280022 nosy: Trundle priority: normal severity: normal status: open title: traceback module can't format/print unhashable exceptions Added file: http://bugs.python.org/file45342/unhashable_exceptions.diff ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28603> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13204] sys.flags.__new__ crashes
New submission from Andreas Stührk andy-pyt...@hammerhartes.de: It's not possible (by intention) to instantiate a new instance of sys.flags. This is achieved by setting the tp_new slot to NULL (in `_PySys_Init()`), after `PyType_Ready()` is called, which means that a slot wrapper is added to the type dict for the tp_new slot (because the slot != NULL at that time). The problem is now that if one calls `sys.flags.__new__` directly, a null pointer dereference occurs in `tp_new_wrapper()`. Attached is a patch that fixes the crash and adds a test. -- files: sys_flags__new__crash.patch keywords: patch messages: 145763 nosy: Trundle priority: normal severity: normal status: open title: sys.flags.__new__ crashes type: crash versions: Python 2.7, Python 3.2, Python 3.3 Added file: http://bugs.python.org/file23431/sys_flags__new__crash.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13204 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Andreas Stührk andy-pyt...@hammerhartes.de added the comment:
That happens because argparse uses `os.basename(sys.argv[0])` (per default) as
program name, but `sys.argv[0]` is usually a string of length 0 at interactive
sessions. The tests use ``usage: {} format(program_name)`` (note that
there will be two spaces for an empty `program_name`) for the expected output,
while argparse only outputs one space in that case.

[issue11813] inspect.getattr_static doesn't get module attributes
New submission from Andreas Stührk andy-pyt...@hammerhartes.de: My patch for issue #11133 introduced a regression: it is no longer possible to get attributes of modules. That is because modules use tp_dictoffset (at C level). The instance __dict__ is exposed to Python code using a types.MemberDescriptorType. My patch for issue #11133 currently assumes that accessing the instance __dict__ can trigger code execution, but that is impossible: The access itself can't trigger code execution (it just returns a PyObject in the C struct). Theoretically, it could return any Python object, but that doesn't matter, as the code that uses the object only calls dict methods directly, hence a TypeError is the worst thing that can happen (although it shouldn't ever happen in practise). Attached is a patch that adds a test and fixes the issue. -- components: Library (Lib) files: getattr_static_modules.patch keywords: patch messages: 133432 nosy: Trundle, michael.foord priority: normal severity: normal status: open title: inspect.getattr_static doesn't get module attributes type: behavior versions: Python 3.2, Python 3.3 Added file: http://bugs.python.org/file21596/getattr_static_modules.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11813 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11770] inspect.dir_static
Andreas Stührk andy-pyt...@hammerhartes.de added the comment: A first patch, misses any documentation changes. While working on it, I realised that modules technically shadow the __dict__ attribute (because modules use tp_dictoffset, hence module have a __dict__ member that points to the instance dict). I updated `_shadowed_dict()` so that it now disregards member descriptors as shadowing (as they will never trigger any code execution), but theoretically, the members can be any object (not just dicts), so I have to think a bit more about that case (as a custom object still can trigger code execution). Also, `dir_static()` behaves slightly different from `dir()` (e.g. `dir()` raises a `TypeError` if the module's __dict__ attribute isn't a dictionary, which is kind of impossible for `dir_static` as it doesn't even try to acccess `__dict__` if it is shadowed), but IMHO such edge-cases are expected to behave differently for a static version and hence we don't care at all about that. -- keywords: +patch Added file: http://bugs.python.org/file21591/issue11770.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11770 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11705] sys.excepthook doesn't work in imported modules
Andreas Stührk andy-pyt...@hammerhartes.de added the comment: I really doubt that this issue has anything to do with `sys.excepthook` at all. It's rather that module members are set to `None` during module cleanup. Because the module raises an exception when one tries to import it, it will be cleaned up immediately (see `PyImport_ExecCodeModuleEx`: it calls `remove_module` which will call at some point `_PyModule_Clear`). At the time when `sys.excepthook` is called, all module members are already set to `None`. One can easily demonstrate that this is really the problem by removing the exception raise in your example code: If one then imports loggingTest in an interactive session and raises an exception, the expected behaviour can be observed. Another workaround is to bind `logger` as a default argument (i.e. ``def handleException(excType, excValue, traceback, logger=logger):``). -- nosy: +Trundle ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11705 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11343] Make errors due to full parser stack identifiable

I agree with Martin (from 2000) that SyntaxError is not right either. Perhaps
a new ParseError subclass thereof.
I added a new `ParserError` that inherits from `SyntaxError`.
I presume REPL == read-eval-print-loop (from Google). Would a new error help
such programs (like code.interact, or IDLE)?
Yes, I meant a read-eval-print-loop. A new error would help and if
it's a subclass of SyntaxError, they most likely need no changes at
all to handle that new error, as they have to deal with SyntaxErrors
anyway.

Whether or not this fixes issue ('should' is a bit vague, confirmation is

Yes, it fixes the issue. I wrote should because I was a bit in a
hurry and hadn't put much thought into whether it's the best way to
fix that issue (or if there even is an issue that should be fixed).
Now that I thought a bit more about it, I think it's a decent fix for
the issue. There is still the possibility that a custom __repr__
method calls `object.__str__`, but that will either raise a
RuntimeError at some point (due to stack exhaustion; if the method is
a Python method) or it's a case of well, don't do that (if the
method is implemented in C).
However, I also do not know where to put it as there is no test_object or
test_typeobject file that I see.
I updated the patch and put a test into test_class which seemed like a
good place for it to me. Also, I did the patch against the 3.1 branch
this time, so it can be forward-ported.

[issue1559549] ImportError needs attributes for module and file name
Andreas Stührk andy-pyt...@hammerhartes.de added the comment: There are some issues with the patch: - The check for size of `args` in `ImportError_init()` is wrong: You can't create an `ImportError` with 3 arguments now (TypeError: ImportError expected 2 arguments, got 3) - `ImportError_clear()` doesn't clear ``self-msg``. - `ImportError_str()` doesn't increase the reference count for ``self-msg`` before returning it. - The code that raises the exception (Python/import.c) doesn't check for error return values: All the calls can return NULL which will cause a segfault due to the uncoditional Py_DECREFs. - Using `PyUnicode_DecodeASCII()` for the module name is wrong (IMHO), it should rather be something like `PyUnicode_DecodeUTF8()` as module names can contain non-ASCII characters in Python 3 and are AFAIK (at least right now) always encoded using utf-8. -- nosy: +Trundle, haypo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1559549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11343] Make errors due to full parser stack identifiable
New submission from Andreas Stührk andy-pyt...@hammerhartes.de:
Currently, if the parser's internal stack is full (as it happens when
the parser tries to parse a deeply nested structure), the parser
writes an error message to stderr and a bare MemoryError is
raised. That way, it is really hard for REPLs do handle input that
causes the parser to exhaust its stack correctly (see e.g. ``python -c
print '(' * 100 + ')' * 100 | python -c import code;
code.interact()``).
In my opinion, a SyntaxError would be great because that way one can
easily see where in the source code the error is caused. One reason
against that (stated by MvL in msg1687) is that it's really
syntactically correct Python and only the parser can't parse it. But
then, the same is also true when there are too many indentation levels
in which case an `IndentationError` is raised (which is a subclass of
`SyntaxError`).
I have attached two patches: The first still raises a `MemoryError`
(for the sake of backward compatibility) but adds a message (too many
opening parens) to it. The second raises a `SyntaxError` instead.

[issue11133] inspect.getattr_static code execution
Andreas Stührk andy-pyt...@hammerhartes.de added the comment: The patch is not sufficient - instances may have a class member __dict__ whilst still having an instance __dict__. Sure, but I don't think there is a way how you can access the instance __dict__ in that case inside Python code. At least I can't think of one. Alternatively the __dict__ property may be provided by a base class and so not available in type(obj).__dict__ but still be provided by a property. I don't think there is any general way to tell whether fetching obj.__dict__ will get an instance dictionary or fetch a __dict__ member from the class or a base-class... (Hence the documented exception.) Why not? ``obj.__dict__`` will fetch the instance dictionary iff there is no class attribute __dict__ in any of the base classes. In the patch,``type.__dict__[__dict__].__get__()`` is used to get (without any doubt) the class dictionary. By looking inside that dictionary, we can now tell whether __dict__ is overwritten: If it isn't overwritten, the dictionary either doesn't have a __dict__ entry at all or the value is a getset_descriptor. So we just need to iterate over a type's mro, look inside each entries' dictionary and stop when a __dict__ entry is found. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11133 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
