[issue12641] Remove -mno-cygwin from distutils
Oscar Benjamin added the comment:
I'm attaching one more patch check_mno_cywin_py34.patch. This is my
preferred patch for Python 3.4 (default). It fixes building with MinGW
and removes all support for using Cygwin gcc with --compiler=mingw32.
The user would see the following error message:
'''
Q:\current\testing\hellotestbuild q:\tools\cygwin\bin -3.3
running build_ext
error: Cygwin gcc cannot be used with --compiler=mingw32
'''
I think that this is reasonable as '-mno-cygwin' is a previously
experimental and now long deprecated, discouraged and discontinued
feature of Cygwin's gcc. Removing support for it in future Pythons
would make problems involving MinGW build (like this one) much easier
to solve in future: there would be no need to consider anything other
than the behaviour of MinGW's gcc.

[issue18300] script_helper._asert_python should set TERM='' by default.
New submission from R. David Murray: See issue 11390 for a discussion, but briefly: there is a bug in the readline library that causes it, on some systems, to emit a control sequence on stdout when readline is first initialized and TERM is set to xterm. The bug can be avoided by setting TERM='', and since assert_python is often used to test output, the bogus characters can cause tests to fail on just some systems. _assert_python should therefore set TERM='' unless the TERM environment variable is passed explicitly by the caller. While this issue probably has minimal impact on the earlier python versions (where only doctest is likely to trigger this bug, because it calls pdb which calls readline), on 3.4 readline is always initialized, and therefore the bug is more likely to cause unexpected test failures. -- messages: 191856 nosy: r.david.murray priority: normal severity: normal stage: needs patch status: open title: script_helper._asert_python should set TERM='' by default. type: behavior versions: Python 2.7, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18300 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18293] ssl.wrap_socket (cert_reqs=...), getpeercert, and unvalidated certificates
Christian Heimes added the comment: Thanks for the pointer about being able to get the server's DER certificate. That will be useful. Is there some reason to return DER but not PEM? Or is this perhaps a bug that could be fixed in a future version of Python's ssl module? It doesn't matter how getpeercert() returns the raw cert. PEM and DER encode the X.509 same in ASN.1 notation. PEM is just the base64 representation with some line breaks surrounded BEGIN/END CERTIFICATE lines. Christian wrote: Optional and required verification makes only a differen[ce] for client side certs. I believe there is one small exception: With SSL_VERIFY_NONE, a client will continue talking with a server with an invalid certificate. With SSL_VERIFY_PEER, when a client fails to verify the server's certificate, the client will terminate the connection. You are referring to server side certs, that is the server provides a cert and the client verifies it. I was talking about client side cert (aka server mode), a rarely used mode in which the client side provides a cert to the server. In CERT_OPTIONAL mode the client is allowed to send no cert. CERT_REQUIRED is mapped to SSL_VERIFY_PEER | SSL_VERIFY_FAIL_IF_NO_PEER_CERT. Ideally, I would like a client to be able to get both of the following from the API: (a) the server's certificate (and chain?), and (b) whether or not the certificate (and chain?) is valid (against a given sets of root certs). In client mode you already have the server's cert and as much of the chain as the peer (server) provides. SSL_VERIFY_NONE makes no difference because the server cert is used in the ClientHello / ServerHello handshake and session key negotiation. Perhaps you are a bit confused by Python's ssl API. Somebody once made the choice to return an empty dict from getpeercert(False) when SSL_VERIFY_NONE is used. That's all. :) http://hg.python.org/cpython/file/76196691b5d0/Modules/_ssl.c#l1098 I'm not sure how much of this functionality the Python developers might be interested in putting into Python 3.4? Given that M2Crypto does not work with Python 3.x at all (at least not yet?), I am interested in finding something that will work with Python 3.x and give me the functionality I want. I'd rather not implement a full wrapper for X509_STORE_CTX and X509 certs. It's way too much code, super complex and easily confuses even experienced developers. Python's ssl module is limited to core functionality by design and choice. However I might be intrigue to implement support for SSL_CTX_set_cert_verify_callback() or SSL_CTX_set_verify(). SSL_CTX_set_cert_verify_callback() has more potential, e.g. def cert_verify_callback(sslsocket, storectx, verify_ok): context = sslsocket.context storectx is a minimal X509_STORE_CTX object and verify_ok the boolean return value of X509_verify_cert(). Without a cert verify callback OpenSSL just uses the return value of X509_verify_cert() (ssl/ssl_cert.c:ssl_verify_cert_chain()). sslsocket gives you access to the peer's cert and chain (with #18233). The callback could be used for multiple uses cases like cert blacklisting, too. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18293 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

This issue is *really* annoying: it makes buildbots almost useless (it is
no more possible to check if a commit introduces a regression). So until
the best fix is decided, I applied a temporary fix (based on changes.diff
written by Vinay Sajip):
New changeset 2a9e1eb3719c by Victor Stinner in branch 'default':
Issue #18081: Workaround ./python -m test_idle test_logging failure
http://hg.python.org/cpython/rev/2a9e1eb3719c
I checked that import warnings; warnings.warn('test') does still use the
custom warning hook in IDLE. I don't know how to test all hooks.

[issue18298] pythonw.exe fails with redirected stderr
Amaury Forgeot d'Arc added the comment:
The proper solution if you use pythonw.exe is to define sys.stdout/sys.stderr
yourself in pythonw.exe::
sys.stdout = open('c:/temp/output.txt', 'w')
IOW, do the redirect from inside the program, don't rely on the shell which (by
design?) does not work correctly with /subsytem:windows binaries.
Again, this is a workaround for 2.7, because no backward-compatible fix could
be found.

[issue17883] Fix buildbot testing of Tkinter
Zachary Ware added the comment: Ok, I've managed to cobble together a buildbot setup to test the hang myself and have come up with a couple possible solutions. The first is to change the buildbot service on the slaves to allow desktop interaction. This way, the tests can actually run. If that's not possible, it's probably simplest to just pass -u-gui to the buildslaves in question, since there is in fact no gui available. That should at least fix the test_ttk_guionly problem. As for the test_tcl problem, how about this patch? It simply wraps the Popen call in a try/except, and converts to a skip in case of an 'Access is denied' error. -- nosy: +pitrou resolution: fixed - Added file: http://bugs.python.org/file30700/issue17883-skip-on-error.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17883 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7796] No way to find out if an object is an instance of a namedtuple
Eric Snow added the comment: A NamedTuple ABC doesn't have to define any API (so that part could wait?)[1]. I see it as most useful for isinstance checks. Here's a solution along those lines: class NamedTuple(Sequence): @classmethod def __subclasshook__(cls, C): if cls is NamedTuple: if any(_fields in B.__dict__ for B in C.__mro__): return True return NotImplemented def namedtuple(...): ... NamedTuple.register(result) return result (or include NamedTuple in the bases in the template) For structseq support: class NamedTuple(Sequence): @classmethod def __subclasshook__(cls, C): if cls is NamedTuple: if any(_fields in B.__dict__ or # for namedtuple n_fields in B.__dict__ # for structseq for B in C.__mro__): return True return NotImplemented [1] I agree there is still a problem if we define an ABC here with no API and then add some later. Then classes that inherit from NamedTuple would break later when we add an API (just `_fields`?). Not sure how much that is a concern though. Then again we could just close out issue1820 and actually establish the API. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7796 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18293] ssl.wrap_socket (cert_reqs=...), getpeercert, and unvalidated certificates
mpb added the comment: Christian wrote: sslsocket gives you access to the peer's cert and chain (with #18233). Very interesting (and useful). I've mostly been working with Python 2.7, and I had not fully noticed that Python 3.2+ has a ssl.SSLContext class. I'd rather not implement a full wrapper for X509_STORE_CTX and X509 certs. It's way too much code, super complex and easily confuses even experienced developers. Python's ssl module is limited to core functionality by design and choice. However I might be intrigue to implement support for SSL_CTX_set_cert_verify_callback() or SSL_CTX_set_verify(). SSL_CTX_set_verify() seems (mostly) redundant SSLContext.verify_mode. Or am I missing something? SSL_CTX_set_cert_verify_callback() has more potential, e.g. def cert_verify_callback(sslsocket, storectx, verify_ok): context = sslsocket.context storectx is a minimal X509_STORE_CTX object and verify_ok the boolean return value of X509_verify_cert(). Without a cert verify callback OpenSSL just uses the return value of X509_verify_cert() (ssl/ssl_cert.c:ssl_verify_cert_chain()). I believe support for SSL_CTX_set_cert_verify_callback() would allow customized certificate verification, which is what I am looking for. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18293 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Oh, it doesn't help for this issue. On Windows, faulthandler is unable to dump
the Python traceback on a stack overflow. On UNIX, it allocates a diffrent
stack for its signal handler, and so the signal handler can run even on a stack
overflow.
The Windows exit code 0xC0FD (3221225725) means Stack overflow /
exhaustion.

(and keyword-only), whereas `parser['section'].get()` behaves like a mapping.
You can do `parser['section'].get('key', 'some-fallback-value')` and
`parser['section'].get('no-such-key')` returns None instead of raising
`NoOptionError`.
This makes it difficult to automagically support parser `get*()` methods on the
section proxy. This is why I decided to adapt a different mechanism: register a
converter and a getter is automatically available:
cp = ConfigParser()
cp.converters['list'] = lambda value: value.strip().split()
cp.getlist('section', 'l')
['a', 'b', 'c']
cp['section'].getlist('l')
['a', 'b', 'c']
cp.getdict('section', 'd')
Traceback (most recent call last):
...
AttributeError: 'ConfigParser' object has no attribute 'getdict'
cp['section'].getdict('d')
Traceback (most recent call last):
...
AttributeError: 'ConfigParser' object has no attribute 'getdict'
This ensures that you can easily add new converters in subclasses or single
instances and that the parser-level API and section-level API work like they
should. This also makes implementing custom getters easier since there's no
logic involved besides the conversion. And if you happen to need custom logic
anyway, you can register a converter that is a callable class.

[issue18303] json.dumps() claims numpy.ndarray and numpy.bool_ are not serializable
miscjunk added the comment: Thanks for the explanation. I suppose this should be posted to the numpy tracker then? Would it be possible for numpy to 'just work' with the json module? Or will the final resolution be to use a handler (the default= parameter in json.loads) ?

[issue18304] ElementTree gets awkward to use if there is an xmlns
New submission from Bryce Nesbitt:
ElementTree offers a wonderful and easy API for parsing XML... but if there is
a namespace involved it suddenly gets ugly. This is a proposal to fix that.
First an example:
--
!/usr/bin/python
# Demonstrate awkward behavior of namespaces in ElementTree
import xml.etree.cElementTree as ET
xml_sample_one = \
?xml version=1.0?
presets
thing stuff=some stuff/
thing stuff=more stuff/
/presets
root = ET.fromstring(xml_sample_one)
for child in root.iter('thing'):
print child.tag
xml_sample_two = \
?xml version=1.0?
presets xmlns=http://josm.openstreetmap.de/tagging-preset-1.0;
thing stuff=some stuff/
thing stuff=more stuff/
/presets
root = ET.fromstring(xml_sample_two)
for child in
root.iter('{http://josm.openstreetmap.de/tagging-preset-1.0}thing'):
print child.tag
--
Because of the namespace in the 2nd example, a {namespace} name keeps
{namespace} getting {namespace} in {namespace} {namespace} the way.
Online there are dozens of question on how to deal with this, for example:
http://stackoverflow.com/questions/11226247/python-ignore-xmlns-in-elementtree-elementtree
With wonderfully syntactic solutions like 'item.tag.split(})[1][0:]'
-
How about if I could set any root to have an array of namespaces to suppress:
root = ET.fromstring(xml_sample_two)
root.xmlns_at_root.append('{namespace}')
Or even just a boolean that says I'll take all my namespaces without
qualification?
