[issue16595] Add resource.prlimit

2013-10-25 Thread Christian Heimes 

Christian Heimes added the comment:

The buildbot is 
Linux-2.6.35-vs2.3.0.36.32-gentoo-i686-Intel-R-_Core-TM-2_CPU_6600_@_2.40GHz-with-gentoo-2.1
 but prlimit() requires 2.6.36+. I didn't expect to see a combination of glibc 
with prlimit() and Kernel without prlimit(). According to man prlimit it's not 
suppose to fail with ENOSYS, too.

[issue19385] dbm.dumb should be consistent when the database is closed

2013-10-25 Thread Claudiu.Popa 

New submission from Claudiu.Popa:

This problem occurred in issue19282. Basicly, dbm.dumb is not consistent with 
dbm.gnu and dbm.ndbm when the database is closed, as seen in the following:


 import dbm.dumb as d
 db = d.open('test.dat', 'c')
 db.close()
 db.keys()
Traceback (most recent call last):
  File stdin, line 1, in module
  File /tank/libs/cpython/Lib/dbm/dumb.py, line 212, in keys
return list(self._index.keys())
AttributeError: 'NoneType' object has no attribute 'keys'


vs

 import dbm.gnu as g
 db = g.open('test.dat', 'c')
 db.close()
 db.keys()
Traceback (most recent call last):
  File stdin, line 1, in module
_gdbm.error: GDBM object has already been closed


Attaching a patch.

Yes, you can create files in a read-only directory if you are root, that's why 
os.chmod(directory, stat.S_IREAD is redundant there.

2013-10-25 Thread Tim Golden 

Tim Golden added the comment:

This is, in principle, a backwards-incompatible change as any code will stop 
working which relies on exec* running useful tools in c:\bin. (I have a 
c:\tools which is basically the same thing).

Frankly, I'm -0 on changing it; it does no real harm that I can see. If we do 
decide to ditch it, I'd only do it for the current release and not backport.

[issue19388] Inflated download counts

2013-10-25 Thread Dustin Oprea 

New submission from Dustin Oprea:

Noah recommended that I approach the distutils mailing list to report a 
potential PyPI problem. I can't seem to find a webpage for the distutils list, 
so I'm posting an official bug.

I have a few packages on PyPI, and I often find my counts immediately taking 
hold, and, for the more useful projects, skyrocketing. However, I recently 
started a service that requires membership. In the last month, PyPI reports 
3000 downloads of the client, yet Google Analytics only reports a handful of 
visits to the website. I have even less membership signups (as expected, so 
soon after launch). Why are the download counts so inflated? Obviously, they're 
very misleading and limited if they don't ignore spurious visitors (like 
robots).

What has to be done to get this to be accurate?

I've included two screenshots of PyPI and GA.

[issue16595] Add resource.prlimit

2013-10-25 Thread Charles-François Natali 

Charles-François Natali added the comment:

 I didn't expect to see a combination of glibc with prlimit() and Kernel 
 without prlimit(). According to man prlimit it's not suppose to fail with 
 ENOSYS, too.

Yeah, we've seen this several times on some buildbots.
Note that actually, any syscall can fail with ENOSYS: the configure
check just checks that the libc exposes the wrapper library, but when
the libc wrapper makes the actual syscall, the kernel can return
-ENOSYS if it doesn't implement the syscall.

[issue19386] selectors test_interrupted_retry is flaky

2013-10-25 Thread Charles-François Natali 

Charles-François Natali added the comment:

This failure doesn't make sense: whether SIGALRM is delivered or not, epoll() 
should time out after 2 seconds, not 105s.

What's more, here's another test_subprocess failure:

==
ERROR: test_wait_timeout (test.test_subprocess.ProcessTestCase)
--
Traceback (most recent call last):
  File 
/var/lib/buildslave/3.x.murray-gentoo-wide/build/Lib/test/test_subprocess.py, 
line 993, in test_wait_timeout
self.assertEqual(p.wait(timeout=3), 0)
  File /var/lib/buildslave/3.x.murray-gentoo-wide/build/Lib/subprocess.py, 
line 1514, in wait
raise TimeoutExpired(self.args, timeout)
subprocess.TimeoutExpired: Command 
'['/var/lib/buildslave/3.x.murray-gentoo-wide/build/python', '-c', 'import 
time; time.sleep(0.3)']' timed out after 3 seconds


Even more strange, a test_asyncio failure:

==
FAIL: test_interrupted_retry (test.test_selectors.EpollSelectorTestCase)
--
Traceback (most recent call last):
  File 
/var/lib/buildslave/3.x.murray-gentoo-wide/build/Lib/test/test_selectors.py, 
line 299, in test_interrupted_retry
self.assertLess(time() - t, 2.5)
AssertionError: 105.86884237639606 not less than 2.5


asyncio uses selectors as backend, so let's admit the test fails, but what's 
really surprising is that the timeout is *exactly* the same, up to the last 
digit.

Something fishy is going on: David, did something change recently on that 
buildbot?

[issue12340] Access violation when using the C version of the io module

2013-10-25 Thread OscarL 

OscarL added the comment:

I can't reproduce the access violation on Windows, using Python 2.7.3.

Using the test_bufio.py script by santa4nt, I can see that the fail still 
happens.

As Santoso Wijaya (santa4nt) said in a previous comment:

The `write(data)` method is getting a `memoryview` object, thus the test code 
should be using `data.tobytes()` instead of using `bytes(data)`. If we 
introduce that logic on the test_bufio.py script it passes.

The thing is that if we, instead of doing `import io` (the C version of the 
module) we do `import _pyio as io` (the pure Python version) the FAIL does not 
appears at all in the original script!

That difference (`write` might receive a `memoryview` object if using the C 
version of this module) is not documented anywhere.

It should, if that's the expected behavior [*], and the code using the io 
module is responsible for using .tobytes() instead of bytes().

[*] Why _pyio.py behaves differently?

R. David Murray added the comment:

The only change on the buildbot for some months now was increasing the size of 
the in-memory /tmp filesystem, which I did yesterday.  That also involved a 
reboot, though, and it is conceivable that there were software changes made 
since the last reboot and before this one.  I don't *think* there were, but I 
can't promise it.  No kernel changes, though, for sure.

[issue19389] find_file might return a different directory than the tested file

2013-10-25 Thread Mathieu Virbel 

New submission from Mathieu Virbel:

With Maverick OSX (latest version), there is no /usr/include/zlib.h anymore. If 
you try to compile Python with -sysroot, it trigger a error message:

error: /usr/include/zlib.h: No such file or directory

The issue is in setup.py, where find_file is checking the existence of a 
filename, but if the filename has been found in a sysroot, it will return the 
path _without_ the sysroot.

In this case (zlib), find_file correctly find the zlib.h in 
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/zlib.h,
 but return /usr/include,  and then the setup.py open '/usr/include/zlib.h', 
which fail.

Nick Coghlan added the comment:

The problem we're trying to solve is CPython *silently* breaking subclass
invariants, which is what the concrete APIs currently do. At the moment,
trying to swap out dicts with ordered dicts in various places will corrupt
the ordered dict instead of calling the appropriate subclass methods or
throwing a type error.

The boilerplate required to use them correctly renders them broken in my

 The boilerplate required to use them correctly renders them broken in my
 view, particularly when they silently corrupt internal subclass state when
 misused instead of throwing an exception.

IMO the boilerplate should actually be included inside the abstract
APIs, so as to automatically enable optimized shortcuts when possible.

[issue19391] Fix PCbuild/readme.txt in 2.7 and 3.3

2013-10-25 Thread Zachary Ware 

New submission from Zachary Ware:

As discussed in issue19273, here are a pair of patches that correct factual 
errors in PCbuild/readme.txt in both 2.7 and 3.3.

The 3.3 patch makes the following changes:
- Remove Win2k mentions, it is not supported (Tcl nmake command also adjusted)
- MSVCRT9 - MSVCRT10
- SQLite 3.7.4 - 3.7.12, remove (see below) with nothing to see
- .vcproj - .vcxproj, all occurrences 
- _bz2.vcxproj isn't as magical as it was made out to be, and it can clean 
itself
- nasmw - nasm
- Remove untrue part of Building for Itanium section
- Update msdn link
- .vsprops - .props
- Trim trailing space

Due to the large number of lines in the diff due to trailing space, I'll also 
be attaching a patch created by `hg diff -w` for ease of review.

 The boilerplate required to use them correctly renders them broken in my
 view

I think we disagree here. There is no boilerplate at all involved, as long
as its guaranteed that they are being called on the correct type of object.
User code may provide that guarantee either implicitly or explicitly, and
only the explicit way involves additional code (such as a type check). The
implicit way (that simply knows the exact type) would suffer from any code
additions to the fast paths in the specific C-API functions.

 particularly when they silently corrupt internal subclass state when
 misused instead of throwing an exception.

It has bothered me more than once that even the fast paths in those
functions usually contain type checks, which often means that the type
check is being executed twice: once as a special casing check before
calling the function and once as a safety check after entering it. As long
as the functions are being used correctly, the second check is just useless
code that unnecessarily takes time.

IMHO, it would be nice to have those internal type checks enabled *only*
for debug builds, although even then, there may be legitimate usages that
call these functions on subtypes (such as when called from within a well
defined subtype implementation, as you mentioned).

[issue10977] Concrete object C API considered harmful to subclasses of builtin types

2013-10-25 Thread Nick Coghlan 

Nick Coghlan added the comment:

Keep in mind that part of the problem here is finding stdlib code that
needs to be fixed to handle subclasses correctly. The existing APIs have
permitted use with subclasses for years but are, in fact, the wrong tool
for that in many cases.

The problem to be solved isn't this code should handle ducktyping but,
this code should either reject subclasses or else handle them without
corrupting them. Using the same API for both external invocation and for
subclasses calling up to the parent is a problem. For code in critical
paths, doing the same type check twice is also a problem.

[issue19389] find_file might return a different directory than the tested file

2013-10-25 Thread Ned Deily 

Ned Deily added the comment:

Thanks for the report.  The issue of setup.py not looking in an OS X SDK for 
zlib.h was recently fixed in currently active branches: f3a2dab1623b (default), 
2d8d5fea6194 (3.3), c207ac413457 (2.7).

By the way, there has been a lot of confusion about the installation of header 
files in OS X 10.9 Mavericks, brought on by Apple itself.  In recent previous 
releases, most header files were only installed in the normal locations 
(/usr/include, /System/Library/Frameworks) as part of the Command Line Tools 
component (either through Xcode or the downloadable standalone package).  Early 
on in the life cycle of Mavericks development, there apparently was an attempt 
to no longer install the header files by the CLT packages, forcing everyone to 
reference them via an SDK.  For whatever reason, that attempt was dropped 
before Mavericks was released.  With the 10.9 CLT properly installed, you 
should see /usr/include correctly populated, including zlib.h.  In 10.9, the 
new way to force CLT to be installed is:

   xcode-select --install

[issue19393] symtable.symtable can return the wrong top SymbolTable

2013-10-25 Thread Steven Winfield 

New submission from Steven Winfield:

The attached script creates calls symtable.symtable many times on a code 
snippet that contains a single class with a method called top, and some other 
important (to trigger the behaviour) properties:
  * a class variable
  * at least three other methods

The symtable module is reloaded each time, which seems to exacerbate the 
problem, but it not necessary.

The return value of symtable.symtable is sometimes a SymbolTable object, as 
expected, and sometimes a symtable.Function object.

Here is some example output from the script:

c:\Python27python.exe C:\Temp\symtable_weirdness.py
Counter({'SymbolTable': 59, 'Function': 41})

c:\Python33python.exe C:\Temp\symtable_weirdness.py
Counter({'SymbolTable': 89, 'Function': 11})

The values are consistent between runs, but can be changed by altering 
PYTHONHASHSEED between runs.

[issue19172] selectors: add keys() method

2013-10-25 Thread Charles-François Natali 

Charles-François Natali added the comment:

 Antoine Pitrou added the comment:

 FWIW, I think the ideal solution would be for keys() (*) to return a
 read-only Mapping implementation, allowing for file object lookup (using
 __getitem__) as well as iteration on SelectorKeys (using __iter__) and
 fast emptiness checking (using __len__).

Thanks, I think that's a great idea.
I'm attaching a patch updating yours with the following:
- asyncio/test_asyncio update
- selectors' documentation update

IMO, it really offers both a compact, easy to use and performant API.

(Note: the mapping doesn't really have to be recreated upon each
get_map() call and could be kept as a private member, but IMO that's
not a performance issue).

[issue19394] distutils.core.Extension: empty strings in library_dirs and include_dirs should not be allowed

2013-10-25 Thread robotron 

New submission from robotron:

When empty string element is passed in include_dirs or library_dirs (e.g. 
include_dirs = []) param of distutils.core.Extension constructor, it is 
propagated to compiler/linker params and in the case of gcc it eats subsequent 
command line option.

setup.py excerpt:

---
extensions = [
Extension(test_extension, [test_extension.cpp],
include_dirs = [],
libraries = [rt],
library_dirs = [],
)
]
---

$ python setup.py build
...
gcc ... -I -I/usr/include/python2.7 -c test_extension.cpp ...

Standard include dir /usr/include/python2.7 is ommited now. The same is valid 
for library_dirs.

Example scripts attached.

[issue4331] Add functools.partialmethod

2013-10-25 Thread alon horev 

alon horev added the comment:

I just want to make sure I understand the semantics concerning class methods, 
the following example demonstrates a usage similar to regular methods as much 
as possible:

class A(object):
def add(self, x, y):
print(self)
return x + y
add10 = partialmethod(add, 10)
add10class = classmethod(partialmethod(add, 10))

assert A().add10(5) == 15 # prints __main__.A object at 0x1097e1390
assert A.add10class(5) == 15 # prints class '__main__.A'

Another option would be to return a class-bound partial from the __get__ 
method. It's not as consistent as the first example but perhaps nicer:

class A(object):
def add(self, x, y):
print(self)
return x + y
add10 = partialmethod(add, 10)

assert A().add10(5) == 15 # prints __main__.A object at 0x1097e1390
assert A.add10(5) == 15 # prints class '__main__.A'

Is the first option what you had in mind?
