[issue14576] IDLE: closes when writing warnings on Windows
Terry J. Reedy added the comment:
I think the next interesting question is to find out why an invalid home
directory causes idle to not start up. There's no obvious reason why that
should be the case in principle,
As Roger showed, IDLE will start up with an invalid home directory.
so I suspect there's some error handling missing somewhere
Yes, the uncaught exception raised when attempting to display a non-essential
but user-useful messages (this is the third issue I know of about this). There
are 5 places in configHandler.py where a warning is directly printed to
sys.stderr. There are two similar writes in PyShell.py. The first warning is
the problem here, but any of them could be a problem and all should be handled
better.
Lib/idlelib\PyShell.py: 1357: sys.stderr.write(Error: %s\n % str(msg))
Lib/idlelib\PyShell.py: 1358: sys.stderr.write(usage_msg)
Lib/idlelib\configHandler.py: 209:sys.stderr.write(warn)
Lib/idlelib\configHandler.py: 223:sys.stderr.write(warn)
Lib/idlelib\configHandler.py: 255:sys.stderr.write(warning)
Lib/idlelib\configHandler.py: 367:sys.stderr.write(warning)
Lib/idlelib\configHandler.py: 624:sys.stderr.write(warning)
Why are warning used instead of message boxes? Perhaps easier, perhaps the
latter are not available because the tk loop is not running. Possible solutions:
* Discard the message by just catching AttributeError (clikkeb) -- at each
place indicated above. This would be better than nothing, but only as a
temporary measure, and there is a better temporary measure below.
* Rearrange the start up process to make message boxes available, with default
configuraton, before the configuration process.
* Make a list of messages and display them when it must (on exit, if that is
possible with atexit) or in message boxes when it can.
* Solve the more general problem of writing to None by making sys.stdout and
sys.stderr not be None, #13582. At minimum, even as a temporary measure, use
something that just swallows output. Something like
import io
class DummyOut(io.IOBase):
def write(self, s):
return len(s)
dum = DummyOut()
print(dum.write('sixsix'))
# 6

[issue16633] os.environ updates only one copy of env vars under Windows (GetEnvironmentVariable vs. getenv)
Jerome Dubois added the comment: We encountered the same issue when upgrading our application's JRE from 1.5 to 1.6. We use a kind of grid, which has engines written in C, which uses an embedded JAVA JVM, which loads C dll. One of these uses python. Here is what happens: 1. C executable launches an embedded JVM, which loads its required dlls. 2. JVM sets PYTHONHOME environment variable through windows kernel API: SetEnvironmentVariable 3. JVM loads our C dlls to start computations 3. One of the dlls invokes Py_InitializeEx, which must read PYTHONHOME in some way (C runtime getenv?). Python 2.5 here, with MSVCR71.dll loaded. 4. Computations are done with invoked python With JRE 1.5, Python is able to get correct PYTHONHOME, and can do import os in our script. With JRE 1.6, this is not the case, as JRE 1.6 loads MSVCR71.dll @ step 1. JRE 1.5 did not. As stated in the previous comments, and from my understanding, in Windows there is the Process Environment Variables Space and possibly several C Runtime Environment Variables Space. The first time a C runtime dll is loaded, it copies the Process Env Var into its own buffer. Our JRE 1.6 loads msvcr71.dll (C runtime), and so copies env var @ step 1. It happens before we set PYTHONHOME with JAVA @ step 2. To correct this, we had to use the Py_SetPythonHome function before calling Py_PyInit to set PYTHONHOME ourselves This way, Python executes our code fine when we use JRE 1.6. But this is because we do not call any getenv functionality within python at the moment, but it could happen in the future... As stated by eudoxos, the safest solution for windows is to use GetEnvironmentVariable (win32 kernel API). Is there any schedule for a fix for this problem? Thanks for you time and answer.

[issue16977] argparse: mismatch between choices parsing and usage/error message
Eric V. Smith added the comment:
Isn't this really just an inappropriate use of a string instead of a list? If
indeed this is in the documentation, it should be changed.
I still don't like:
p.add_argument('a', choices=list('abc'))
but at least it would work.
This call to list() could be done internally, but I think passing in a string
is a bad practice and argparse should not contain internal workarounds to cater
to this usage.
If you're proposing that argparse should use sequence iteration instead of the
in operator, I disagree with that solution.

[issue15448] utimes() functions fail with ENOSYS even when detected by configure
Charles-François Natali added the comment:
There are actually two distinct issues.
For the first one, the problem is really a distribution issue: the libc is more
recent than the kernel, and exports *utimes() whereas the kernel doesn't
implement those syscalls, which results in ENOSYS.
I don't like the idea of adding explicit check for this, because any syscall
can fail with ENOSYS (we've had recently pipe2(), accept4(), etc).
It's really a distribution issue.
For the second one, it seems that RHEL6.4 doesn't have utime() anymore, which I
find really strange (although POSIX.1-2008 marks utime() as obsolete).
Could you provide the output of:
$ strace ./python -c import os; os.utime('.')

I have one question and that is about the value PARSER=A... for nargs, it's a valid option and there are test cases with nargs=A..., however it is not listed in the documentation: http://docs.python.org/dev/library/argparse.html#nargs -- keywords: +patch nosy: +ReDAeR Added file: http://bugs.python.org/file28759/argparse.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16970 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue16977] argparse: mismatch between choices parsing and usage/error message
Chris Jerdonek added the comment:
This wasn't just in the documentation. It was the *first* example of how to
use the choices argument out of the two examples in that section (from the time
Python first adopted argparse and before):
16.4.3.7. choices
Some command-line arguments should be selected from a restricted set of values.
These can be handled by passing a container object as the choices keyword
argument to add_argument(). When the command line is parsed, argument values
will be checked, and an error message will be displayed if the argument was not
one of the acceptable values:
parser = argparse.ArgumentParser(prog='PROG')
parser.add_argument('foo', choices='abc')
parser.parse_args('c'.split())
Namespace(foo='c')
parser.parse_args('X'.split())
usage: PROG [-h] {a,b,c}
PROG: error: argument foo: invalid choice: 'X' (choose from 'a', 'b', 'c')
(from
http://hg.python.org/cpython/file/c0ddae67f4df/Doc/library/argparse.rst#l1021 )
So I think it's a bit late to say it's an inappropriate usage or bad practice.
To preserve backwards compatibility, I think we should use sequence iteration
for strings, or equivalently apply in to iter(choices), set(choices), etc.
when choices is a string. I don't think, however, that we should alter the
choices attribute because that could break things for people:
p = argparse.ArgumentParser()
a = p.add_argument(letter, choices='abcd')
a.choices
'abcd'

[issue16989] allow distutils debug mode to be enabled more easily
New submission from Chris Jerdonek: This issue is to allow distutils's debug mode [1] to be enabled more easily (e.g. programmatically). Currently, for example, distutils.core does the following: from distutils.debug import DEBUG (from http://hg.python.org/cpython/file/cb297930d2cf/Lib/distutils/core.py#l12) which means that it's not sufficient to set the DEBUG attribute on the distutils.debug module. Instead, to enable debug mode programmatically you have to do something like the following prior to importing from distutils: import os os.environ['DISTUTILS_DEBUG'] = 1 # for False or 1 for True. This issue can be fixed simply by changing the affected import statements from importing the value to importing just the module (and subsequently accessing the value via the module).

[issue16468] argparse only supports iterable choices
Chris Jerdonek added the comment: I have a new suggestion that I hope will satisfy Terry. After looking at the code more, I noticed that add_argument() does currently work for non-iterable choices provided that metavar is passed. This was also noted in the report for the duplicate issue 16697. On reflection, this makes sense because that's what metavar is for -- providing a replacement string for the usual formatting in the help text. The only thing that doesn't work in this case is error message formatting. With that, I'd like to propose the following: (1) Change the add_argument() error raised for non-iterable choices from: ValueError(length of metavar tuple does not match nargs) to something like: ValueError(metavar must be provided for non-iterable choices) This provides the help string representation for non-iterable choices (in the spirit of Explicit is better than implicit). (2) Make the error text the following for non-iterable choices (the error message currently breaks for non-iterable choices): PROG: error: argument FOO: invalid choice: 'xxx' compared with (for iterable choices)-- PROG: error: argument FOO: invalid choice: 'xxx' (choose from ...) I think this is preferable to inserting the str() or repr() (especially for maintenance releases) because str() and repr() may not be meant for displaying to the end-users of a script. The instructions/description of such choices is already in the add_argument() help string. We could consider appending that to provide substantive guidance. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16468 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Chris Jerdonek added the comment: Actually, let me relax (1). We can just use what the argparse code calls the default_metavar in that case (which it constructs from the argument name).

[issue16991] Add OrderedDict written in C
New submission from Eric Snow: Here's an initial stab at writing OrderedDict in C. Though, the implementation is not heavily optimized and isn't super subclass-friendly, my hope is that it's relatively close to the final version. I'm getting this up now to get some eyes on it. The spot in the builtins is mostly for convenience, but I expect it will need to be exposed somewhere (perhaps _collections?). My experience with the C-API is relatively limited and my C-fu is not at a professional level. However, I'm pretty sure that I have most everything correct. The ultimate goal for this type is to use it for **kwargs. Note: this first patch has some reference leaks that I'm tracking down. -- assignee: eric.snow components: Interpreter Core files: odict.diff keywords: patch messages: 180170 nosy: eric.snow, rhettinger priority: normal severity: normal stage: patch review status: open title: Add OrderedDict written in C type: enhancement versions: Python 3.4 Added file: http://bugs.python.org/file28762/odict.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16991 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
