[issue13238] Add shell command helpers to shutil module

[Nick Coghlan]

Nick Coghlan  added the comment:

The first version I wrote *did* automatically invoke shlex.quote on all 
interpolated values, but that breaks wildcard handling. You can see that in the 
examples I posted above. With the default whitespace escaping (which allows 
spaces in filenames), wildcard matching still works (thus the list of 
directories matching the "../py*" pattern), but with full quoting it breaks 
(thus the "nothing named '../py*'" result).

So I figured the simplest default was "you can have spaces in your filenames, 
but otherwise you can do what you want". Now that I have the 'unquoted' 
conversion specifier, I'm open to tweaking that scheme to allow the same chars 
that shlex.quote does *plus* specifically the wildcard matching chars (i.e. 
'*', '?').

[issue13281] robotparser.RobotFileParser ignores rules preceeded by a blank line

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Because of the line break, clicking that link gives "Server error 404".
http://www.robotstxt.org/norobots-rfc.txt
works (so please pay attention to formatting). The main page is
http://www.robotstxt.org/robotstxt.html 

The way I read the grammar, 'records' (which start with an agent line) cannot 
have blank lines and must be separated by blank lines. Other than than, the 
suggestion seems reasonable, but it also seems like a feature request. Does 
test/test_robotparser pass with the patch?

I also do not see "Crawl-delay" and "Sitemap" (from whitehouse.gov) in the 
grammar referenced above. So I wonder if de facto practice has evolved.

Philip S.: do you have any opinions?
(I am asking you because of your comments on #1437699.)

[issue1681674] subprocess.Popen fails with socket._fileobject on Windows

[James Burgess]

James Burgess  added the comment:

"Can't Fix" that is not true. 

I've just fixed this in 2.7 with a trivial change to subprocesss.py, I think 
it'd work in over versions too.

Note that type shenanigans are already in play in _get_handles, it's looking at 
the types of the parameters being passed in to decide how to get a hold of the 
"handle". The socket module makes a duck type of the file object. The fileno() 
method of the socket object returns a handle not a CRT file descriptor. This is 
exactly the kind of handle that _get_handles() is looking for.

So all that is needed is one more "if" to the sequence of how to get the 
"handle" which for a socket object would be just stdin.fileno() etc.

I've just tested this in a fairly complicated remote job queuing software (a 
commercial product) that has the ability to connect the spooler (on one 
machine) with an arbitrary server machine (linux, osx and now windows) via a 
socket. The job is launched with subprocess.Popen and sockets are wired into 
the stdin,stdout and stderr. Works beautifully now.

I've attached a patch file made with:
$ diff -c subprocess.py.ORIG subprocess.py  > subprocess.py.patch

Apply with:
$ cd  Python-2.7.1/Lib ; patch -p0 < c:/temp/subprocess.py.patch

Cheers,
- James

[issue13275] Recommend xml.etree for XML processing

[Terry J. Reedy]

Terry J. Reedy  added the comment:

In the tutorial, "The xml.dom and xml.sax packages" should be expanded to "The 
xml.dom, xml.sax, and xml.etree packages". I suspect that the current line 
predates the addition of .etree.

We try to mostly not give opinion-based recommendations; the docs are for 
facts. Some people recommend using lxml instead of any of the above ;-).

"The documentation for the xml.dom and xml.sax packages are the definition of 
the Python bindings for the DOM and SAX interfaces."

could be followed by a factual sentence like "xml.etree provides an  third 
alternative."

Looking more: the intro to 19.6. xml.dom — The Document Object Model API nicely 
explains the difference between SAX and DOM processing as sequential versus 
random access. The intro to 19.13. xml.etree.ElementTree — The ElementTree XML 
API says nothing about how it compares to the others. Perhaps the sentence 
should be "xml.etree provides a tree-based interface different from xml.dom." 
(assuming this is a fact). Make your suggestion.

[issue13288] SSL module doesn't allow access to cert issuer information

[John Nagle]

New submission from John Nagle :

The SSL module still doesn't return much information from the
certificate.  SSLSocket.getpeercert only returns a few basic items
about the certificate subject.  You can't retrieve issuer information,
and you can't get the extensions needed to check if a cert is an EV cert.

With the latest flaps about phony cert issuers, (another CA compromise hit the 
news today) it's worth having issuer info available.
It was available in the old M2Crypto module, but not in the current Python SSL 
module.

Oh, sorry, it's d1d251292ee7. (I got the short rev from the hg.python.org 
interface, so I thought it would be "authoritative" enough, but I guess it is 
ambiguous)

>> importing shutil from the stdlib is broken in that file besides.
> I don’t understand this.
When I do "import shutil" inside _backport/shutil.py, it seems to be importing 
itself (??) if I don't explicitly enable absolute imports (in python 2.7). If I 
delete the "class Error" definition and instead add "from shutil import Error", 
I get an ImportError.

Let's deprecate some of these (or add deprecation warnings) for
upcoming release.  But, doing from xxx import * is not a recommended
way for any module, as we know that it stands to pollute the namespace
with unneccesary functions/methods. I would be careful in adding
anything to __all__ and if done, may go for only 3.3. Ezio has a valid

This looks like a local revision number, which has no meaning outside of one 
specific repository.  What is the changeset identifier?  (see 
http://hgbook.red-bean.com/read/a-tour-of-mercurial-the-basics.html#id345536)

Thanks for the diagnosis!  Code calling functions from the backported shutil 
should obviously catch exceptions from the backported shutil.  I’ll review all 
modules using the backport.

FYI, some distutils2 modules use shutil from the stdlib, for functions that are 
already here in 2.4; not sure if that is good or bad.

> Ideally, I think distutils2/_backport/shutil.py should do "from shutil import 
> Error"
> instead of defining its own Error class
Oh, no, our backported module is strictly independent from the stdlib one.

> importing shutil from the stdlib is broken in that file besides.
I don’t understand this.

[issue13287] urllib.request exposes too many names

[Florent Xicluna]

New submission from Florent Xicluna :

>>> len(dir())
4
>>> import urllib.request import *
>>> len(dir())
88


In this list we find 14 modules:
['base64', 'collections', 'ssl', 'bisect', 'http', 're', 'email', 'socket', 
'os', 'posixpath', 'hashlib', 'io', 'time', 'sys']

And many non-documented functions:
 - ftperrors
 - getproxies_environment
 - getproxies_macosx_sysconf
 - localhost
 - noheaders
 - parse_http_list
 - parse_keqv_list
 - proxy_bypass
 - proxy_bypass_environment
 - proxy_bypass_macosx_sysconf
 - quote
 - randombytes
 - request_host
 - urlunparse
 - splitattr
 - splithost
 - splitpasswd
 - splitport
 - splitquery
 - splittag
 - splittype
 - splituser
 - splitvalue
 - thishost
 - to_bytes
 - unquote
 - unwrap
 - urljoin
 - urlparse
 - urlsplit

It may be good to define __all__ for this module, and to preprend "_" on some 
of these names.

The custom formatter idea sounds brilliant.  Can you test that auto-escaping of 
spaces works well with glob patterns?

[Guido]
> What's holding this up?

- I haven’t updated the patch for function and module objects yet
- I need to catch up with the python-ideas discussion
- There is at least one strong argument against the idea (I’ll point it out on 
the ML)

[issue13286] PEP 3151 breaks backward compatibility: it should be documented

[STINNER Victor]

STINNER Victor  added the comment:

The first example was extracted from Lib/importlib/_bootstrap.py. The code was 
maybe wrong, I don't know.

Another example:
--
import errno
import os

try:
os.rmdir("testdir")
except:
pass
os.mkdir("testdir")

try:
try:
#os.mkdir("testdir")
open("NOT EXISTING FILENAME")
except OSError as exc:
if exc.errno == errno.EEXIST:
pass
else:
raise
except IOError as exc:
if exc.errno == errno.ENOENT:
pass
else:
raise
except Exception:
raise
print("PEP 3151 broke backward compatibility on such pattern!")
--

Uncomment mkdir() to test both paths.

[issue13285] signal module ignores external signal changes

[Vilya Harvey]

Vilya Harvey  added the comment:

Could it return an opaque wrapper object, rather than just the raw address? 
Something like:

typedef struct _PyNativeSignalHandler {
  PyObject_HEAD
  sighandler_t handler_func;
} PyNativeSignalHandler;

where the type object doesn't expose any way to read or manipulate the 
handler_func. Would that work, do you think?

[issue13286] PEP 3151 breaks backward compatibility: it should be documented

[STINNER Victor]

New submission from STINNER Victor :

The following example works on Python 2.7 and 3.2, but fails on Python 3.3:
---
import errno
import os

try:
os.rmdir("testdir")
except:
pass
os.mkdir("testdir")

try:
try:
os.mkdir("testdir")
except IOError as exc:
# If can't get proper access, then just forget about writing
# the data.
if exc.errno == errno.EACCES:
pass
else:
raise
except OSError as exc:
# Probably another Python process already created the dir.
if exc.errno == errno.EEXIST:
pass
else:
raise
except Exception:
print("PEP 3151 broke backward compatibility on such pattern!")
---

I noticed the problem while reading the changeset e4d44c2e8e81.

[issue13285] signal module ignores external signal changes

[Charles-François Natali]

Charles-François Natali  added the comment:

> So it's impossible to reliably save and restore signal handlers through

signal.getsignal() or signal.signal() return the current/previous handler as a 
Python function. How could it return a reference to a native (i.e. C) signal 
handler?
While we could in theory return it as a magic cookie (i.e. the handler's 
address as returned by sigaction/signal) that can just be passed back to 
signal.signal(), it would be a bad idea: if the user passes an invalid address, 
the process will crash when the signal is received.

[issue13244] WebSocket schemes in urllib.parse

[Tobias Oberstein]

Tobias Oberstein  added the comment:

Is that patch supposed to be in Python 2.7.2?

If so, it doesn't work for "ws":

"ws://example.com/somewhere?foo=bar#dgdg"

F:\scm\Autobahn\testsuite\websockets\servers>python
Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from urlparse import urlparse
>>> urlparse("ws://example.com/somewhere?foo=bar#dgdg")
ParseResult(scheme='ws', netloc='example.com', path='/somewhere?foo=bar#dgdg', 
params='', query='', fragment='')
>>> urlparse("ws://example.com/somewhere?foo=bar#dgdg", allow_fragments = True)
ParseResult(scheme='ws', netloc='example.com', path='/somewhere?foo=bar#dgdg', 
params='', query='', fragment='')
>>> urlparse("ws://example.com/somewhere?foo=bar#dgdg", allow_fragments = False)
ParseResult(scheme='ws', netloc='example.com', path='/somewhere?foo=bar#dgdg', 
params='', query='', fragment='')
>>>

urlparse will neither parse the query nor the (invalid) fragment component for 
the "ws" scheme

I would have expected

ParseResult(scheme='ws', netloc='example.com', path='/somewhere', params='', 
query='foo=bar', fragment='dgdg')

[issue13238] Add shell command helpers to shutil module

[Nick Coghlan]

Nick Coghlan  added the comment:

I realised I could use the convert_field() option in the custom formatter to 
choose between several interpolation quoting options:

  default - str + shutil.quote_ascii_whitespace
  !q - str + shlex.quote
  !u - unquoted (i.e. no conversion, str.format default behaviour)
  !s - str (as usual)
  !r - repr (as usual)

The most recent commit also exposes public APIs for the formatting aspects 
(shutil.quote_ascii_whitespace, shutil.shell_format, shutil.shell_format_map)

[issue13284] email.utils.formatdate function does not handle timezones correctly.

[Burak Arslan]

Burak Arslan  added the comment:

turns out timetuple was not passing timezone information. the correct way of 
converting a datetime.datetime object to a correct rfc-2822 compliant date 
string seems to be:

email.utils.formatdate(time.mktime(a.utctimetuple()) + 1e-6 * a.microsecond - 
time.timezone)

what a mess. if the above is indeed the right way to do this, is it possible to 
add the following function to the email.utils module?

def formatdatetime(dt_object):
return email.utils.formatdate(time.mktime(dt_object.utctimetuple()) + 1e-6 
* a.microsecond - time.timezone)

this works for datetime instances both with and without time zone information.

ps: i updated the code in the github link but not here.

[issue13285] signal module in ignores external signal changes

[Vilya Harvey]

New submission from Vilya Harvey :

The signal module is oblivious to any changes to the set of installed signal 
handlers which occur outside of the module. This can happen when a native 
module changes a signal handler, or when the python interpreter is embedded in 
another program which installs its own signal handlers.

In this case, saving and restoring a signal handler through python doesn't work 
correctly. For example, if the SIGINT handler is set externally after the 
signal module is initialised, the following code will replace the external 
signal handler with python's default_int_handler:

  handler = signal.getsignal(signal.SIGINT)
  signal.signal(signal.SIGINT, handler)

So it's impossible to reliably save and restore signal handlers through python 
when they can also be changed outside the python interpreter.

Also, if there's a signal handler installed before the module is initialised, 
signal.getsignal() will return None for it - making it impossible to restore 
the correct handler after disabling it.

The reason is that the signal module only checks for existing handlers when 
it's initialised. The results get stored in the Handlers array, which is then 
used by all subsequent calls to signal.getsignal(). There are no further checks 
to see whether the native signal handlers have changed.

[issue13284] email.utils.formatdate function does not handle timezones correctly.

[Burak Arslan]

New submission from Burak Arslan :

There's an issue with email.utils.formatdate function, illustrated here: 
https://gist.github.com/1321994

for reference i'm on Europe/Istanbul timezone, which is +03:00 because of DST 
at the time of this writing.

I'm on stable Python 2.7.2 on gentoo linux. 

When I run the attached script, I get:

Fri, 28 Oct 2011 07:56:14 -
datetime.datetime(2011, 10, 28, 9, 56, 14, 945831, tzinfo=)

when the local time is 12:56. so the second line is correct and first one is 
not.

let me know if you need any more information.
thanks for your attention.

[issue10363] Embedded python, handle (memory) leak

[Martin Dunschen]

Martin Dunschen  added the comment:

Hello Antoine

Unloading would not be necessary if the DLL is just the python interpreter,
but if you build a DLL with python embedded that does quite a bit more than
some python interpreting (in my case complex C/C++ numerical calculations)
unloading the DLL is a convenient way to free up unused resources. There are
C++ classes that extend python in my code (via swig), and that's where the
size of the DLL get's increased.

If the handle leaks are restricted to the windows implementation of cpython,
could it not be justified to allow C++ in a patch, I can't think of a C only
compiler for windows?

Thanks

Martin
