[RELEASE] six 1.7.0
I'm pleased to announce the immediate availability of six 1.7.0. six is a small Python 2/3 compatibility library. The most interesting change in this release is yet another implementation by Anselm Kruis of six.moves using a sys.meta_path hook. Hopefully, this will cause less issues with the various tools that iterate blindly over sys.modules. Downloads are on PyPI: https://pypi.python.org/pypi/six Documentation is available on Read the Docs: http://six.readthedocs.org/ Here is the changelog for 1.7.0: - Pull request #30: Implement six.moves with a PEP 302 meta path hook. - Pull request #32: Add six.wraps, which is like functools.wraps but always sets the __wrapped__ attribute. - Pull request #35: Improve add_metaclass, so that it doesn't end up inserting another class into the hierarchy. - Pull request #34: Add import mappings for dummy_thread. - Pull request #33: Add import mappings for UserDict and UserList. - Pull request #31: Select the implementations of dictionary iterator routines at import time for a 20% speed boost. -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
Fwd: ANN: Intro+Intermediate Python, San Francisco, Jul 30-31, Aug 1
Greetings! I'll be offering another hardcore Python course this summer near the San Francisco airport. If you're somewhat new to or have some Python experience under your belt already but want to fill-in the holes, this course is for you. Why take a real course when you can learn Python online or by reading books? Well, my goal isn't to teach Python syntax, which you can from any teacher, live or online, or from giant books. My job is to create great Python developers and removing the roadblocks that impede your path to getting there. This intensive course is based on my Core Python (http://corepython.com) books and is made up of 3 full days complete with lectures and several hands-on coding labs per day. t's also a great excuse to coming to beautiful Northern California for a summer vacation! Groups and development teams are welcome as well as individuals. I do more private gigs and fewer of these public courses lately, so please come join if you can... my next public intro/intermediate course may not be for awhile, so I'm hoping to meet some of you this time around! Sign up soon... there's a special earlybird rate for the rest of this month before going up to the regular rate after that. More details and registration at http://cyberwebconsulting.com as well as in the ad: http://goo.gl/pyJseQ I'm no fan of spam, so I'll only send out one last reminder as the date gets closer... say around the end of June.

mimedecode.py version 2.6.0
Hello! mimedecode.py WHAT IS IT Mail users, especially in non-English countries, often find that mail messages arrived in different formats, with different content types, in different encodings and charsets. Usually this is good because it allows us to use appropriate format/encoding/whatever. Sometimes, though, some unification is desirable. For example, one may want to put mail messages into an archive, make HTML indices, run search indexer, etc. In such situations converting messages to text in one character set and skipping some binary attachments is much desirable. Here is the solution - mimedecode.py. This is a program to decode MIME messages. The program expects one input file (either on command line or on stdin) which is treated as an RFC822 message, and decodes to stdout or an output file. If the file is not an RFC822 message it is just copied to the output one-to-one. If the file is a simple RFC822 message it is decoded as one part. If it is a MIME message with multiple parts (attachments) all parts are decoded. Decoding can be controlled by command-line options. Version 2.6.0 (2014-06-08) Make options -e/-i to work with multipart subparts. Add option -I to completely ignore a part - no headers, no body, no warning. Open all output files in binary mode. Output os.linesep instead of '\n'. Test --save-headers|body|message masks one after another to allow saving a message or a subpart to more than one file. WHAT'S NEW in version 2.5.0 (2014-03-18) Add option --set-header=header:value to set header's value (only at the top level). Add option --set-param=header:param=value to set header parameter's value (only at the top level). The header must exist. Add option -B to skip content-transfer-decoding binary attachments. Add options --save-headers, --save-body and --save-message to save decoded headers/bodies/messages to files. Add option -O to set the destination directory for output files. Fix a minor bug: if a multipart message (or a subpart) lacks any textual content - avoid putting an excessive newline.

ANNOUNCING eGenix.com pyOpenSSL Distribution Version 0.13.3.1.0.1.8 An easy-to-install and easy-to-use distribution of the pyOpenSSL Python interface for OpenSSL - available for Windows, Mac OS X and Unix platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-pyOpenSSL-Distribution-0.13.3.1.0.1.8.html INTRODUCTION The eGenix.com pyOpenSSL Distribution includes everything you need to get started with SSL in Python. It comes with an easy-to-use installer that includes the most recent OpenSSL library versions in pre-compiled form, making your application independent of OS provided OpenSSL libraries: http://www.egenix.com/products/python/pyOpenSSL/ pyOpenSSL is an open-source Python add-on that allows writing SSL/TLS- aware network applications as well as certificate management tools: https://launchpad.net/pyopenssl/ OpenSSL is an open-source implementation of the SSL/TLS protocol: http://www.openssl.org/ NEWS This new release of the eGenix.com pyOpenSSL Distribution updates the included OpenSSL version to the latest OpenSSL 1.0.1h version and adds a few more context options: New in OpenSSL -- * Updated included OpenSSL libraries from OpenSSL to 1.0.1h. See http://www.openssl.org/news/secadv_20140605.txt for a complete list of changes, most important: - CVE-2014-0224: An attacker can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. This can be exploited by a Man-in-the-middle (MITM) attack where the attacker can decrypt and modify traffic from the attacked client and server. - CVE-2014-0221: By sending an invalid DTLS handshake to an OpenSSL DTLS client the code can be made to recurse eventually crashing in a DoS attack. Only applications using OpenSSL as a DTLS client are affected. - CVE-2014-3470: OpenSSL TLS clients enabling anonymous ECDH ciphersuites are subject to a DoS attack. New in pyOpenSSL * Added the following new options for context.set_options(): OP_TLSEXT_PADDING, OP_SAFARI_ECDHE_ECDSA_BUG, OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION, OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION. * Documented all supported context.set_options() options (to the extent possible using the OpenSSL documentation itself). pyOpenSSL / OpenSSL Binaries Included - In addition to providing sources, we make binaries available that include both pyOpenSSL and the necessary OpenSSL libraries for all supported platforms: Windows x86 and x64, Linux x86 and x64, Mac OS X PPC, x86 and x64.

There is a fundamental thermodynamic limit on the minimum energy needed to flip a bit from one state to the other, so in that sense there's a relationship between watts and bits per second. We're nowhere near reaching that limit with current technology, though. In principle, our CPUs could be a lot more energy-efficient.

It means they would need less energy input in the first place). -- Greg -- https://mail.python.org/mailman/listinfo/python-list
asyncio - how to stop loop?
Hi all
I have a 'start.py' script that kicks off my program by starting a number of
services.
For now, I stop it by allowing the user to press enter, after which I
close down the services and stop the program. (For production I imagine it
would be better to run it in the background and send it some kind of signal
to terminate, but for testing this suffices.)
As one of the services is a 'listening' loop, which would normally prevent
access to the keyboard, I start it in a separate thread. For example, when I
was using cherrypy as the server, I had -
server = cherrypy.wsgiserver.CherryPyWSGIServer((host, port),
dispatcher)
threading.Thread(target=server.start).start()
input('Press enter to stop')
server.stop()
Now I am playing with asyncio, but I cannot get it to behave the same.
Here are my attempts. I use python 3.4.1, and I tested on Windows and
Linux - the results are different on each platform.
First attempt - same as before
loop = asyncio.get_event_loop()
threading.Thread(target=loop.run_forever).start()
input('Press enter to stop')
loop.stop()
loop.close()
Windows traceback -
Exception in thread Thread-1:
Traceback (most recent call last):
File C:\Python34\lib\threading.py, line 920, in _bootstrap_inner
self.run()
File C:\Python34\lib\threading.py, line 868, in run
self._target(*self._args, **self._kwargs)
File C:\Python34\lib\asyncio\base_events.py, line 184, in run_forever
self._run_once()
File C:\Python34\lib\asyncio\base_events.py, line 795, in _run_once
event_list = self._selector.select(timeout)
AttributeError: 'NoneType' object has no attribute 'select'
With Linux, it does not terminate. If I press Ctrl_C, I get this traceback
(hope there are no typos) -
Traceback (most recent call last):
File /usr/local/lib/python3.4/threading.py, line 1294, in _shutdown
t.join()
File /usr/local/lib/python3.4/threading.py, line 1060, in join
self._wait_for_tstate_lock()
File /usr/local/lib/python3.4/threading.py, line 1076, in
_wait_for_tstate_lock
elif lock.acquire(block, timeout):
KeyboardInterrupt
Second attempt - move the keyboard input to a separate thread
def stop_loop():
input('Press enter to stop')
loop.stop()
loop.close()
loop = asyncio.get_event_loop()
threading.Thread(target=stop_loop).start()
loop.run_forever()
With Windows, it works - the program closes cleanly.
With Linux, it does not terminate. If I press Ctrl_C, I get this traceback
(hope there are no typos) -
Traceback (most recent call last):
File test_async.py, line 20, in module
loop.run_forever()
File /usr/local/lib/python3.4/asyncio.base_events.py, line 184, in
run_forever
self._run_once()
File /usr/local/lib/python3.4/asyncio.base_events.py, line 795, in
_run_once
event_list = self._selector.select(timeout)
File /usr/local/lib/python3.4/asyncio.selectors.py, line 424, in select
fd_event_list = self._epoll.poll(timeout, max_cv)
KeyboardInterrupt
Third attempt - get the loop to close itself (cannot use in practice, but
see what happens)
def stop_loop():
loop.stop()
loop.close()
loop = asyncio.get_event_loop()
loop.call_later(2, stop_loop)
loop.run_forever()
Both platforms show the same traceback, after two seconds -
Traceback (most recent call last):
File C:\Documents and Settings\frank\aib\aib_async\test_async.py, line
29, in module
loop.run_forever()
File C:\Python34\lib\asyncio\base_events.py, line 184, in run_forever
self._run_once()
File C:\Python34\lib\asyncio\base_events.py, line 795, in _run_once
event_list = self._selector.select(timeout)
AttributeError: 'NoneType' object has no attribute 'select'
Can anyone suggest a way to get the loop to stop cleanly?
Thanks
Frank Millman

There's a big difference between a car that gets 100 miles to the gallon, and one that gets 1 mile to the gallon. With a car, the engine converts some of its energy to kinetic energy, which is subsequently dissipated as heat, so it makes sense to talk about the ratio of kinetic energy produced to energy wasted directly as heat. But when you flip a bit, there's no intermediate form of energy -- the bit changes state, and heat is produced. So all of the heat is waste heat. -- Greg -- https://mail.python.org/mailman/listinfo/python-list

In practice, all cars do have fans (even the ones that aren't air-cooled), for the occasions when they're not moving that fast.

基于cython的即时编译器cyjit，欢迎大家提建议
我正在写一个使用cython code作为后端的即时编译器名为cyjit，将python code 转换为cython code再编译为c
extension导入.设计上主要参考numba.jit的思路，使用decorate来指定要编译的function，例如：
from cyjit import jit
@jit('int(int,int)')
def add(a,b):
return a+b
add(1,2)#compiled
@jit('int(int,int)',
locals='''
int c
''')
def add1(a,b):
c=add(a,b)# fast invoked
return c
add1(1,2)
目前还不支持类型推导，需要手动使用c的语法对局部变量进行定义。
编译过程是在jit函数中完成的，后续计划将编译过程移到函数运行时完成，实现重载。
目前支持编译cache，第一次运行需要编译，时间稍慢，再次运行直接导入编译好的extension，速度就很快了。
欢迎大家fork，pull，提建议。

Python's re module and genealogy problem
For some genealogical purposes I consider using Python's re module. Rather many names can be spelled in a number of similar ways, and in order to match names even if they are spelled differently, I will build regular expressions, each of which is supposed to match a number of similar names. I guess that there will be a few hundred such regular expressions covering most popular names. Now, my problem: Is there a way to decide whether any two - or more - of those regular expressions will match the same string? Or, stated a little differently: Can it, for a pair of regular expressions be decided whether at least one string matching both of those regular expressions, can be constructed? If it is possible to make such a decision, then how? Anyone aware of an algorithm for this? -- https://mail.python.org/mailman/listinfo/python-list

A CPU has to have a fan, but a car engine doesn't, because the car's moving at a hundred kays an hour. I have a suspicion the CPU fan moves air a bit slower than that. I'm not sure where Chris' message comes from, I can't see the original, so I'm guessing the context. Air cooled cars don't just cool the engine when they are travelling at 100kmh. Some air-cooled engines used a fan to blow extra air over the cooling fins, but many did not. Normal air flow is sufficient to keep them in a safe operating temperature, the hot engine warms the air, which flows away and is replaced by cooler air. It's possible to design CPUs to work the same way. My wife is using a PC right now with a 1.66GHz Atom CPU and no CPU fan. Even though the power supply fan died, the machine is still running perfectly, with two laptop HDDs, and no overheating. 1.66GHz is plenty fast enough for web browsing, word processing, email, etc. Go back 30 years, and I don't think that the average PC needed a CPU fan. Possibly not even a case fan. Just the normal air flow over a small heat sink was enough. And of course, your mobile phone has no room for a heat sink, unless it's tiny, and no fan. And people expect it to keep working even when shoved in their pocket. If the car were *always* moving at 100km/h, it probably wouldn't need a fan. In practice, all cars do have fans (even the ones that aren't air-cooled), for the occasions when they're not moving that fast. That may be true of water-cooled engines *now*, but it's not a law of engineering. Many air-cooled engines do not (did not) require a fan, or only needed the extra cooling when stuck idling for long periods in hot weather. E.g. Beetles didn't use a fan. (A great idea for Germany, not so much for hot and dusty Southern California, as my wife can tell you.) (BTW, so-called water-cooled engines are really air-cooled too, just not by air flowing directly over the engine block. (Although marine engines may be an exception.)) Yes, technically water-cooled engines are cooled by air too.

Re: asyncio - how to stop loop?

First attempt - same as before
loop = asyncio.get_event_loop()
threading.Thread(target=loop.run_forever).start()
input('Press enter to stop')
loop.stop()
loop.close()
Each event loop is hosted by a specific thread. In this case you're
getting the event loop of the main thread and then trying to run it in
a separate thread, which is not a good idea. You can run an event
loop in a separate thread, but you should install a separate event
loop for that thread if you do (and then when you interact with the
loop, do so in a thread-safe manner -- see below).
Second attempt - move the keyboard input to a separate thread
def stop_loop():
input('Press enter to stop')
loop.stop()
loop.close()
loop = asyncio.get_event_loop()
threading.Thread(target=stop_loop).start()
loop.run_forever()
One issue here is that (like most event loop implementations) event
loops are not thread-safe. To make a call to the event loop across
threads, you should be using the call_soon_threadsafe method, e.g.
loop.call_soon_threadsafe(loop.stop). You'll also want to make sure
that the event loop has actually stopped before you call loop.close --
see below.
Third attempt - get the loop to close itself (cannot use in practice, but
see what happens)
def stop_loop():
loop.stop()
loop.close()
loop = asyncio.get_event_loop()
loop.call_later(2, stop_loop)
loop.run_forever()
I think what's happening here is that per the docs loop.close should
not be called while the loop is running. You've called loop.stop but
you're still inside a callback, which is a bit of a gray area. You
probably don't need to call loop.close at all, but if you want to do
so I suggest putting it after the run_forever call, so you can be
certain the loop has stopped when it's called.
Putting all that together, you should have something like this:
def stop_loop():
input('Press enter to stop')
loop.call_soon_threadsafe(loop.stop)
loop = asyncio.get_event_loop()
threading.Thread(target=stop_loop).start()
loop.run_forever()
loop.close() # optional

Just a feeling-based statement: I don't think that is easily possible.
Every RE can potentially match an infinite number of statements.
Just have a look at
re1 = re.compile('A43.*')
re2 = re.compile('.*[0-9][A-F]')
It can easily seen that the area these REs work on is different; they
are orthogonal.
So there is an infinite number of strings these REs match.

Hi,
i guess, you could reuse some available generators for strings
matching a given regular expression, see e.g.:
http://stackoverflow.com/questions/492716/reversing-a-regular-expression-in-python/
for example a pyparsing recipe:
http://stackoverflow.com/questions/492716/reversing-a-regular-expression-in-python/5006339#5006339
which might be general enough for your needs - of course, you cannot
use unbound quantifiers, backreferences, etc.
Then you can test for identical strings in the generated outputs -
e.g. using the set(...) and its intersection method.
You might also check a much more powerful regex library
https://pypi.python.org/pypi/regex
which, beyond other features, also supports the mentioned fuzzy matches, cf.
regex.findall(r\bSm(?:ith){e3}\b, Smith Smithe Smyth Smythe Smijth)
['Smith', 'Smithe', 'Smyth', 'Smythe', 'Smijth']
(but, of course, you will have to be careful with this feature in
order to reduce false positives)

Ultimately, I have to make a decision, because code can't be impartial - either I'm using some module or I'm not - and it's usually impossible to truly become educated on all the options. So I'd say there's more of a spectrum between your choices 1 and 3 than you imply. Perhaps I can word it this way: Choose one of the options you know about, and the quality of the decision scales with the number of other options you also know. (Which is why I like to know huge numbers of programming languages. When I choose Python for a job, it's because it's better than possibly a hundred other languages that I could have chosen.)

A JIT compiler 'cyjit' using cython code as a backend
I'm writing a JIT compiler named cyjit using cython code as a backend. It
designed primarily reference numba.jit. the jitted python function will be
converted to cython code then compiled to c extension.
Use decorate to specify compiled function.
for example:
from cyjit import jit
@ jit ('int (int, int)')
def add (a, b):
return a + b
add (1,2) # compiled
@ jit ('int (int, int)',
locals ='' '
int c
'' ')
def add1 (a, b):
c = add (a, b) # fast invoked
return c
add1 (1,2)
Currently cyjit does not support type defer, the local variables can be
defined manually using C syntax.
Jit compilation process is done inside jit decorate. I am planing to
move compilation process into function's runtime to achieve overload like
numba.jit.
Currently cyjit supports compilation cache, the compilation will happen at
the first run, it will take longer time. When you run it again, it will load
the compiled extension directly.

The engine heats a coolant (despite the name, usually not water these days) which then heats the air. Not water??? I'm not aware of any water-cooled engines which use anything other than water. Well, OK, it's really a solution of ethylene or propylene glycol in water, but the water is what does most of the heat transfer. The glycol is just there to provide freezing point depression and boiling point elevation. Would you consider it fair to say that, say, vinegar is not water? Depending on the type of vinegar, it is typically around 5-10% acetic acid, and the rest water. Spirit vinegar can be as much as 20% acetic acid, which still leaves 80% water. How about brandy, which is typically 35%-60% alcohol, with most of the rest being water? Or household bleach, which is typically a 3-6% solution of sodium hypochlorite? Or milk (85-90% water)? I think it is fair to describe those as not water. You shouldn't try to put out a fire by pouring a bottle of brandy on it. Automotive cooling fluid in modern sealed radiators is typically a mixture of 50% anti-freeze and 50% water. Back in the day, car radiators were *literally* water-cooled in the sense that the radiator was filled with 100% water. You filled it from the tap with drinking water. In an emergency, say broken down in the desert, you could drink the stuff from the radiator to survive. If you tried that with many modern cars, you would die a horrible death. -- Steven D'Aprano http://import-that.dreamwidth.org/ -- https://mail.python.org/mailman/listinfo/python-list

You know, I think that the people of Hiroshima and Nagasaki and Chernobyl and Fukushima (to mention only a few places) might disagree. We know *much more* about generating energy from E = mc^2 than we know about optimally flipping bits: our nuclear reactions convert something of the order of 0.1% of their fuel to energy, that is, to get a certain yield, we merely have to supply about a thousand times more fuel than we theoretically needed. That's about a thousand times better than the efficiency of current bit-flipping technology. We build great big clanking mechanical devices out of lumps of steel that reach 25% - 50% of the theoretical maximum efficiency: https://en.wikipedia.org/wiki/Thermal_efficiency while our computational technology is something of the order of 0.1% efficient.

It is also less work to change. The particular form marks it as not a normal comment. Refinement 2: put all imports that are specific to the htest function at the top of the function. Since the function is only called once per process, there is no efficiency consideration. I decided that after the tkinter import at the top got me (wasting time) looking through UndoDelegator for a widget call that might be the source of the leak.

I prefixed name with 'x' and all leaks disappeared. When I run the test, a tk
box is left. My guess is that something is being created with
tkinter._default_root as master. I do not think it is in UndoDelegator, so I
would look at Percolator, WidgetDirector, Delegator, and the new test file.

See review comment for increasing coverage to about 80%, which is very good.

When unittest call precedes htest.run call, need exit=False or htest is skipped
by unittest exiting process. Part of testing is running tests from module. Even
with the addition, htest is not running right (buttons in main windows are not
right). The might be an effect of the unittest not being properly terminated.
It is still true after I added the missing re import. Htest runs fine by
itself. See #21624 for changes. Revised code:

The sys.frozen flag is not an official Python API and it's unlikely to become one, since you can freeze the whole application or just parts of it, which sys.frozen would not be able to address. Instead, the modules in the stdlib should be aware of the fact that __file__ is not always available and provide fallback solutions. Could you please use a fix that works for Python tools in general ? E.g. instead of doing an equal test inf .findCaller() it may be better to use a regular expression or you could patch the __init__ module's co_filename into the module as _srcfile (after it's fully initialized).

Vinay Sajip added the comment:

I suggested an alternative implementation altogether in Issue #16778, but it
was suggested that we wait for frame annotations. I'm not sure what the
schedule for that is.
The sys.frozen flag is not an official Python API and it's unlikely to become
one
Would using imp.is_frozen('logging') rather than hasattr(sys, 'frozen') meet
your requirement here? I'm not saying it's the ideal solution, but perhaps it
will do until frame annotations arrive and we can avoid using filenames
altogether?

I don't think any of this is needed here. _srcfile is only used to
identify the caller's stack frame and needs to be set to the co_filename
of the stack frame used by the logging.__init__ module.
Here's a sketch of what I had hinted at in my last reply:
def _get_module_filename():
return getLogger.func_code.co_filename
You simply use the .co_filename attribute of one of the module's functions
to get useable value for __file__.

[issue21717] Exclusive mode for ZipFile and TarFile
New submission from Antony Lee: I noticed that while lzma and bz2 already support the x (create a new file, raise if it already exists) flag, zipfile and tarfile don't know about it yet. It would be an useful addition, just as it is useful for regular open. A quick look at both modules show that this likely only requires a little bit more than updating the checks in the corresponding constructors to allow x mode, as the modes are passed (nearly) transparently to the open() builtin. -- components: Library (Lib) messages: 220249 nosy: Antony.Lee priority: normal severity: normal status: open title: Exclusive mode for ZipFile and TarFile versions: Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21717 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue3068] IDLE - Add an extension configuration dialog
Tal Einat added the comment: Ned, many thanks for the review and detailed feedback! Here are responses to your comments 1. Thanks for the code suggestion regarding the menudefs! That's a good catch. I have an OSX box for such testing. 2. I'll check this out. Could you perhaps explain or point me to resources regarding how to run IDLE with various Tk implementations on OSX? 3. Unfortunately, IDLE's config mechanism doesn't have special support for options with only several valid values, as would have been ideal for ParenMatch's style parameter. As it is, these are just considered strings, and no explicit error occurs if an invalid value is specified. Without upgrading the config mechanism itself, the config dialog has no way of supplying the valid values and/or validating user input of such values. This could be useful, but should be considered a separate issue IMO. I would be happy to add relevant support to the dialog once the underlying support is implemented. 4. Regarding having thing updated only on new windows or after restart, AFAIK that is currently the case with many options in the existing config dialog. Ideally the behavior would be consistent for all config options, and even more ideally all config changes would take effect immediately. However, that would require major changes to IDLE. Again, I think this is outside the scope of this issue. 5. I completely agree that the button for boolean options looks horrible. Suggestions for a better Tk widget to use are welcome!

[issue21719] Returning Windows file attribute information via os.stat()
New submission from Ben Hoyt: I asked recently on python-dev [1] about adding a st_winattrs attribute to stat result objects on Windows, to return the full set of Windows file attribute bits, such as hidden or compressed status. Copying from that thread for a bit more context here: Python's os.stat() simply discards most of the file attribute information fetched via the Win32 system calls. On Windows, os.stat() calls CreateFile to open the file and get the dwFileAttributes value, but it throws it all away except the FILE_ATTRIBUTE_DIRECTORY and FILE_ATTRIBUTE_READONLY bits. See CPython source at [2]. Given that os.stat() returns extended, platform-specific file attributes on Linux and OS X platforms (for example, st_blocks, st_rsize, etc), it seems that Windows is something of a second-class citizen here. There are several questions on StackOverflow about how to get this information on Windows, and one has to resort to ctypes. For example, [3]. To solve this problem, I think we should add a st_winattrs attribute to the object returned by os.stat() on Windows. And we should add the relevant Win32 FILE_ATTRIBUTE_* constants to the stat module. Then, similarly to existing code like hasattr(st, 'st_blocks') on Linux, you could write a cross-platform function to determine if a file was hidden, something like so: def is_hidden(path): if startswith(os.path.basename(path), '.'): return True st = os.stat(path) return getattr(st, 'st_winattrs', 0) FILE_ATTRIBUTE_HIDDEN != 0 There was general support for this idea on python-dev (see [4] [5] [6]), so I'd love to see this in Python 3.5. Basically we need to add a st_winattrs integer attribute to the win32_stat struct in posixmodule.c and add the FILE_ATTRIBUTE_* constants to _stat.c, as well as adding Windows-specific tests and documentation. I've never compiled CPython on Windows, but I aim to provide a patch for this at some stage soonish. Feedback and other patches welcome in the meantime. :-) [1] https://mail.python.org/pipermail/python-dev/2014-June/134990.html [2] https://github.com/python/cpython/blob/master/Modules/posixmodule.c#L1462 [3] http://stackoverflow.com/a/6365265 [4] https://mail.python.org/pipermail/python-dev/2014-June/134993.html [5] https://mail.python.org/pipermail/python-dev/2014-June/135006.html [6] https://mail.python.org/pipermail/python-dev/2014-June/135007.html -- components: Library (Lib) messages: 220266 nosy: benhoyt, ethan.furman, zach.ware priority: normal severity: normal status: open title: Returning Windows file attribute information via os.stat() type: enhancement versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21719 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
