[issue14246] Accelerated ETree XMLParser cannot handle io.StringIO

2012-03-13 Thread Stefan Behnel


Stefan Behnel sco...@users.sourceforge.net added the comment:

FWIW, lxml also has support for parsing Unicode strings. It doesn't encode the 
input, however, but parses straight from the underlying buffer (after detecting 
the buffer layout etc. at module init time - and yes, I still haven't fixed 
this up for PEP393).

There is one problem that I see with encoding it to UTF-8 first, even 
disregarding the obvious inefficiency in terms of both memory and processing 
time. At least for string parsing, lxml has an additional check in place that 
rejects Unicode string input containing an encoding declaration, because that 
would be very unlikely to match the buffer encoding on a given platform.

In your case, it would be good to have something similar, because when you get 
a Unicode string with, say, an ISO8859-1 encoding declaration, encoding it to 
UTF-8 and then passing that to pyexpat will silently generate incorrect content 
- unless you can safely enforce a specific encoding regardless of the 
declaration, don't know how expat handles this (you are clearly not handling it 
in your patch, which, I take it, only adapts the behaviour to what pyET 
currently does).

The problem here is that it's not so easy to do this for file-like objects, 
because they may return text that contains ?xml version='1.0', then a 
billion whitespace characters, and then encoding='latin1'?. The XML parser 
could handle this, but doing it in a preprocessing step would be some work.

In any case, silently returning broken data is not a good idea. Maybe it would 
work to check the encoding that the parser uses against the one we expect? If 
the parser switches encodings at some point even though we are sure it *must* 
be utf-8 (in whatever spelling), we can still raise an error at that point. 
I'll consider letting lxml do this check as well, it sounds more efficient than 
what it currently does.

[issue14246] Accelerated ETree XMLParser cannot handle io.StringIO

2012-03-13 Thread Eli Bendersky


Eli Bendersky eli...@gmail.com added the comment:

Stefan,

Thanks a lot for taking the time to review the patch. As you correctly say, the 
current pathch's goal is just to align with existing behavior in the Python 
implementation of ET.

I understand the problem you are describing, but at least it's not a regression 
vs. previous behavior, while the original problem this issue complains about 
*is* a regression.

I propose to commit this to fix the regression and open a separate issue with 
the insight you provided. One easy solution could be to just require the 
encoding to be UTF-8 when passing unicode to the module, and to document it 
explicitly. Another solution would be to actually fix it in the module itself.

If there is a decision to fix it, the fix should then cover both the C and 
Python implementations, in all possible places (all functions reading XML from 
strings will also suffer from the same problem, since they get passed to 
xmlparse_Parse in pyexpat, which just uses PyArg_ParseTuple with the s# 
format - encoding unicode in utf-8 without looking at the XML encoding itself).

[issue14273] distutils2: logging handler not properly initialized

2012-03-13 Thread Vinay Sajip


Vinay Sajip vinay_sa...@yahoo.co.uk added the comment:

I cannot reproduce this, and in fact couldn't find anywhere in packaging in the 
default branch where a distutils2 logger is set up. I used grep to look for 
getLogger.*(distutils2|__name__), could some other logic be in use to 
construct the logger name?

Looking at packaging.run.main() - it calls Dispatcher(args), and any exception 
in Dispatcher.__init__() before the call to _set_logger could lead to a logging 
call being made before a handler is set up.

Suggestion: set the handler as early as possible, perhaps in main() where the 
other handlers logic is, and just set the level later (as that is the only 
thing that depends on verbosity settings passed in via command line flags).

A couple of things I don't quite understand:

1. Why are the packaging logger's handlers are saved and restored en masse - 
all that is happening is that a handler is being added in 
Dispatcher._set_logger, so it would seem to be enough to call removeHandler().

2. There should normally be no need to set both the logger's *and* and 
handler's level to the same value - if the event fails the logger's level test, 
it will not be passed to handlers anyway. In packaging code I found no 
reference to any other loggers than packaging - i.e. no child loggers whose 
events might need to be blocked at the handler level.

In an effort to walk through bugs in my nosy list, I dug into this and tried to

Also, as the handle_error method is supposed to handle problems gracefully, 
calling shutdown on handle_error exception is probably questionable. I'd be 
happy to submit a patch to do just that if those smarter than I think it is 
worthwhile, but I don't so much believe it is.

[issue1762561] unable to serialize Infinity or NaN on ARM using marshal

Nir Soffer nir...@gmail.com added the comment:

As someone who has to develop on ARM OABI, I find this won't fix policy rather 
frustrating.

If you happen to need this patch on 2.7, this is the same patch as 
arm-float2.diff, which can be applied cleanly to release 2.7.2.

Changes from arm-float2.diff:
- Remove whitespace only changes
- Replace tabs with spaces
- Fixed indentation in changed code

Enjoy.

[issue13889] str(float) and round(float) issues with FPU precision


Stefan Krah stefan-use...@bytereef.org added the comment:

I've looked at the latest patch: It seems that new_387controlword is
not set if old_387controlword already has the desired precision and
rounding mode.

Attached is a revised patch that uses the same logic as the Linux
version. A couple of remarks:

  - It would be possible to negate (_PC_53|_RC_NEAR) instead of
enumerating (_MCW_DN|_MCW_EM|_MCW_IC). I found it nice to
see all possibilities listed.

  - Technically we might need to use #pragma fenv_access (on). I'm not sure
where though: If it is set in pyport.h, VS complains that Py_MATH_PI / 180.0
is not constant.


The patch is tested on win32/x64. Additionally, the patch is tested
with setting the rounding mode to _PC_64 in main.c. Then, the
patch is tested with replacing the 'if' bodies by 'abort()'. This
shows that in the regular build (_PC_53 on startup) the bodies of
the if statements are never executed.

Finally, inserting an #error after #if defined(_MSC_VER)  !defined(_WIN64)
on the x64 build shows that !defined(_WIN64) really does its job.

[issue10945] bdist_wininst depends on MBCS codec, unavailable on non-Windows


Éric Araujo mer...@netwok.org added the comment:

The proposition of using other C functions and changing the bdist_wininst code 
looks risky to me, especially as I don’t know how compatibility would be 
affected (see my previous message).  We are free to improve the wininst code in 
distutils2, or discuss a replacement (Jeremy Kloth was working on something 
with all the features of MSI and wininst), but for distutils I would very much 
prefer the simplest fix that could possibly works.

bdist_msi decodes data read from setup.py with MBCS on Windows; on other OSes, 
couldn’t the locale preferred encoding be used?

I think that's actually a bug in python-modernize, not in touch_import - or, 
rather, touch_import shouldn't be used to add future imports.

Instead, I think there should be a touch_future function which adds a future 
import, taking into account that future imports need to go before all other

[issue5758] fileinput.hook_compressed returning bytes from gz file


Éric Araujo mer...@netwok.org added the comment:

Thanks.  Unless another core dev wants to do a complementary review I will 
slightly tweak the patch and commit it.  I need to finish waking up and eat 
some food before I do that :)

Technically adding a new argument means that this is a new feature and cannot 
be applied to the stable 3.2 version, but something needs to be done for this 
bug in 3.2 too, like a recipe in the docs for a hook_compressed that returns 
strings (i.e. a function that calls fileinput.hook_compressed and wraps it in a 
TextIOWrapper), or at least a note to warn about this bug.

[issue10945] bdist_wininst depends on MBCS codec, unavailable on non-Windows


STINNER Victor victor.stin...@gmail.com added the comment:

 Would the proposed change mean that a bdist_wininst built
 with 3.2.0 won’t work with a patched 3.2.3?

The installer doesn't use distutils to read its configuration, so such binary 
runs with any installed Python version.

 bdist_msi decodes data read from setup.py with MBCS on Windows;
 on other OSes, couldn’t the locale preferred encoding be used?

It would be worse: Linux doesn't use Windows code page. Most modern OSes are 
now using UTF-8 locale encoding, whereas Windows never use UTF-8 as the ANSI 
code page.

[issue14127] add st_time_ns fileds to os.stat(), add ns keyword to os.utime(), os.utimens*() expects a number of nanoseconds


STINNER Victor victor.stin...@gmail.com added the comment:

The following changes has to be done to fix this issue:

 - add st_atime_ns, st_mtime_ns and st_ctime_ns fileds to os.stat() result: 
number of nanoseconds since Epoch (1970.1.1), an integer
 - change os.*utime*() functions (see below)
 - shutil.copystat() should use os.utime(ns=...) and os.ltime(ns=...)

List of the os.*utime*() functions:

 - os.futimes(): use futimens() or futimes()
 - os.futimens(): use futimens(); UTIME_NOW and UTIME_OMIT flags
 - os.futimesat(): use utimensat() or futimesat()
 - os.lutimes(): use futimesat(AT_SYMLINK_NOFOLLOW) or lutimes()
 - os.utime(): use SetFileTime() (Windows), utimensat(), utimes() or utime()
 - os.utimensat(): use utimensat(); UTIME_NOW and UTIME_OMIT flags

Changes on the os.*utime*() functions:

 - add ns keyword to:

   * os.futimes()
   * os.futimesat()
   * os.lutimes()
   * os.utime()

 - except a number of nanoseconds instead of a number of seconds:

   * os.futimens()
   * os.utimensat()

The ns keyword is an exclusive parameter with existing times parameter. 
Examples:

   * seconds: os.utime(name, (1, 2))
   * seconds: os.utime(name, times=(1, 2))
   * nanoseconds: os.utime(name, ns=(1, 2))
   * INVALID! os.utime(name, (1, 2), ns=(1, 2))
   * INVALID! os.utime(name, times=(1, 2), ns=(1, 2))

I don't want to remove os.futimens() and os.utimensat() because they add a 
feature: UTIME_NOW and UTIME_OMIT flags.

[issue13889] str(float) and round(float) issues with FPU precision


Mark Dickinson dicki...@gmail.com added the comment:

BTW, the MSDN documentation at

http://msdn.microsoft.com/en-us/library/e9b52ceh(v=vs.100).aspx

is a bit confusing.  Question 1:  when doing __control87_2(new, mask, old, 
NULL), does the resulting value in old reflect the *new* FPU state or the old 
one?

Question 2:  in the example near the bottom of that page, there's code like:

control_word_x87 = __control87_2(_PC_24, MCW_PC,
 control_word_x87, 0);

This looks very odd: we're assigning to control_word_x87, *and* passing it as 
an output parameter to the call.  Moreover, from the documentation  the return 
value from __control87_2 is always 1 to indicate success, so I'm not sure why 
it's being assigned to control_word_x87.

Am I the only person who's confused by this?

Éric Araujo mer...@netwok.org added the comment:

Patch looks good.

I don’t know if I should fix this in 3.3 with your patch or go back to the 
first idea of adding a copystat(src, dst) after the mkdir call.  I just don’t 
know if it’s important that this behavior does not change in stable versions, 
or if it’s clearly a bug and we can change it.

[issue14273] distutils2: logging handler not properly initialized

Éric Araujo mer...@netwok.org added the comment:

We didn’t give enough info, sorry. This bug is not reproducible with
packaging, it only shows when using the distutils2 repository with Python 2.5,
2.6 or 3.1. I think it’s related to the absence of built-in handler of last
resort.

(packaging’s logger is named “packaging” and d2’s is “distutils2”, that’s why
your grep did not find it. This is one of the few differences between both
codebases that I will fix before the betas.)

Looking at packaging.run.main() - it calls Dispatcher(args), and any
exception in Dispatcher.__init__()
before the call to _set_logger could lead to a logging call being made before
a handler is set up.
Suggestion: set the handler as early as possible, perhaps in main() where the
other handlers logic is, and
just set the level later (as that is the only thing that depends on verbosity
settings passed in via
command line flags).
Thanks, I will try that!

1. Why are the packaging logger's handlers are saved and restored en masse -
all that is happening is that
a handler is being added in Dispatcher._set_logger, so it would seem to be
enough to call removeHandler().
Tarek added that in d53e813ffe58 to fix regrtest warnings about test_packaging
modifying logging._handlers.

2. There should normally be no need to set both the logger's *and* and
handler's level to the same value -
if the event fails the logger's level test, it will not be passed to handlers
anyway. In packaging code I
found no reference to any other loggers than packaging - i.e. no child
loggers whose events might need to
be blocked at the handler level.
Yes, the whole package only uses one logger, and we don’t want to stop
messages: the application (pysetup, pip, etc.) must be able to set the level.
I’ll remove the code that sets a level on the logger and write a test to make
sure that a client can get all messages.

[issue12365] URLopener should support context manager protocol


Éric Araujo mer...@netwok.org added the comment:

Thanks for the patch.
 
-   This function returns a file-like object with two additional methods from
+   This function returns a file-like object that supports the Context Manager 
+   protocol, with two additional methods from

The capitalization seems unneeded to me.  Also, in my opinion saying 
“file-like” implies support for the context manager protocol, even if not all 
file-likes do, and anyway not all users share my assumption.  What do you think 
about this wording:

This function returns a file-like object that works as a :term:`context 
manager`
and has two additional methods from the :mod:`urllib.response` module

The term role creates a link to the glossary.  (BTW the entry for context 
manager could be improved to give open as example; I’ll do that.)

+It is also possible to achieve the same result using a context manager
+approach. ::

I would rather use with statements everywhere, or if it makes sense to have 
examples both with and without with, to put the example with with first.

I was confused as well. I'm positive that it's a cut-and-paste bug in the docs:
Probably they had _control87() in that place before, which *does* return the
new control word. As you say, the example above clobbers the value that was set
via the pointer reference, so the result is always 1. :)

[issue5758] fileinput.hook_compressed returning bytes from gz file


R. David Murray rdmur...@bitdance.com added the comment:

For 3.2 could we use the same fix, but without exposing the ability to *change* 
the encoding?  That is, we use TextIOWrapper but always with the default None 
for encoding.

It also occurs to me that this really exposes a weakness in the design.  What 
if the user wants to specify other open parameters?  I wonder if we should say 
that for better future-proofing openhooks should always take **kw.  You could 
even envision fileinput accepting **kw and passing them along to the openhook.  
I think charset is the most important open paramenter in this context, though, 
so I don't think we have to solve the general problem in this fix.

It also occurs to me that this fix makes the charset hook look rather odd.  We

I concur.  I’ve never had to care about buffering for example, but mode is 
another parameter of open that people may want to give.  I’ll commit the 
minimal fix to 3.2 and merge in 3.3, and then we can discuss on a new RFE bug 
about adding encoding vs. **kwargs for 3.3.

Agreed on deprecating the charset hook when it becomes redundant.

Will fix the doc bug about codecs.open too.

[issue14288] Make iterators pickleable

2012-03-13 Thread Kristján Valur Jónsson


New submission from Kristján Valur Jónsson krist...@ccpgames.com:

A common theme in many talks last year about cloud computing was the need to 
suspend execution, pickle state, and resume it on a different node.  This patch 
is the result of last year's stackless sprint at pycon, finally completed and 
submitted for review.

Python does not currently support pickling of many run-time structures, but 
pickling for things like iterators is trivial.
A large piece of Stackless' branch is to make sure that various run-time 
constructs are pickleable, including function objects.  While this patch does 
not do that, it does add pickling for dictiter, and the lot.
This makes it possible to have compilcated data sets, iterate through them, and 
pickle them in a semi-consumed state.

Please note that a slight hack is needed to pickle some iterators.  Many of 
these classes are namely hidden and there is no way to access their 
constructors by name.  instead, an unpickling trick is to invoke iter on an 
object of the target type instead.  Not the most elegant solution but I didn't 
want to complicate matters by adding iterator classes into namespaces.  Where 
should stringiter live for example?  Be a builtin like str?

We also didn't aim to make all iterators copy.copy-able using the __reduce__ 
protocol.  Some iterators actually use internal iterators themselves, and if a 
(non-deep) copy were to happen, we would have to shallow copy those internal 
objects.  Instead, we just return the internal iterator object directly from 
__reduce__ and allow recursive pickling to proceed.

[issue14262] Allow using decimals as arguments to `timedelta`

2012-03-13 Thread Alexander Belopolsky


Alexander Belopolsky alexander.belopol...@gmail.com added the comment:

I am -0 on the feature and -1 on the implementation.  Conversion from Decimal 
to float is explicit by design.  Decimal gives the user fine control over 
rounding issues allowing for either exact arithmetics (trapping inexact 
operation) or one of several rounding modes.

This said, timedelta(decimal) is not much worse than float(decimal), so I 
will be only -0 if the implementation is such that (1) timedelta(decimal) 
does no loose precision over the entire range of timedelta and rounding is 
documented; and (2) implementaton does not require an explicit import decimal 
inside the datetime  module.

[issue14062] UTF-8 Email Subject problem

2012-03-13 Thread Tatiana Al-Chueyr


Tatiana Al-Chueyr tatiana.alchu...@gmail.com added the comment:

Hi msladek!

I tried to reproduce your bug using Python 3.2.2 on MacOS X, but didn't manage 
- all worked fine. I used gmail both to send and receive the message, on SSL:
smtpPort = '465'
smtpSrv = 'smtp.gmail.com'

As I'm no SMPTP nor email expert, I asked r.david.murray to review the email 
message code received and it looks fine.

Could you provide a smaller example of code that causes the same problem?

I just extracted your code to help other people trying to reproduce the bug. It 
is attached.

[issue8536] Support new features of ZLIB 1.2.4

2012-03-13 Thread Jason Killen


Jason Killen jsnk...@gmail.com added the comment:

Given this is marked as good for a newbie and easy I figured I'd take a crack 
at it but I'm confused.  As example I don't see where inflateReset2 would be 
useful.  I don't see anywhere inflateReset is used and would need to be 
replaced by inflateReset2.  I also don't see where the action of inflateReset2 
(End then Init) is currently used.  What am I missing?

[issue14127] add st_time_ns fileds to os.stat(), add ns keyword to os.utime(), os.utimens*() expects a number of nanoseconds


Martin v. Löwis mar...@v.loewis.de added the comment:

 I don't want to remove os.futimens() and os.utimensat() because they add a 
 feature: UTIME_NOW and UTIME_OMIT flags.

I'm not sure how this could work: UTIME_NOW and UTIME_OMIT have 
typically values such as ((1l  30) - 2l) which could be mistaken
as a time stamp if there is a flat nanosecond value.

There would be ways to solve this, of course: not passing the
value should be considered as UTIME_OMIT, and passing -1 may
be treated as UTIME_NOW.

As you can see, Seznam is adding a lot of headers into mail's body. Anyway, 
making utf-8 subject manually like this:

base64Subject = base64.b64encode(subject.encode('utf-8')).decode()
encodedSubject = '=?UTF-8?B?{0}?='.format(base64Subject)
message.add_header('Subject',encodedSubject)

works correctly for both SMTP servers. So there must be a difference...

[issue14289] Prebuilt CHM file on Docs download page

2012-03-13 Thread Nam Nguyen


New submission from Nam Nguyen bits...@gmail.com:

Before 2.7, one can easily find .CHM files in the Documentation download page. 
When 2.7 come out, the only way to get CHM files is downloading the Windows 
installers (EXE or MSI), installing it on Windows, and grabbing the CHM files. 
This is unwieldy.

I am on a Mac at work, have a desktop running Linux and Windows at home. In all 
cases, I usually rely on the CHM file. It is self-packaged, indexable, and 
easily searchable. There are CHM readers out there that work across different 
OSes such as the cross platform xCHM.

Therefore, I'd like to request for a prebuilt .CHM file for download, in 
addition to what there already are.

[issue14290] Importing script as module causes ImportError with pickle.load

2012-03-13 Thread Robert


New submission from Robert bobbyr...@gmail.com:

I implemented a data-structure as an object in a script, let's call it 
objectScript.py. I'm using this data-structure in other scripts like so:

from objectScript import data-structure

Populating this data-structure requires quite a bit of time, so when I'm done 
with it, I like to pickle it. However, if I try to load it from the pickled 
file, I get the following error:

ImportError: No module named objectScript

However, if I replace my 'from objectScript import data-structure' statement 
with the actual data-structure class definition from the objectScript.py file 
when I am pickling the object but then revert to the import statement when I am 
unpickling the object, everything works fine.

[issue829370] math.signum(int)


Mark Dickinson dicki...@gmail.com added the comment:

I disagree that this is useful enough to make it worth adding to the standard 
library.  Between math.copysign and simple comparisons, I think all the common 
cases are well covered.  And it's a simple one-line function:

def signum(x):
return (x  0) - (x  0)

Frank, do you have any convincing use-cases that aren't already covered by 
math.copysign or simple two-way comparisons (e.g., x = 0)?

Georg Brandl ge...@python.org added the comment:

The CHMs are already on the Python download page, along with the .msi 
installers.

We can add a note to the docs download page that they are to be found there.

[issue14291] Regression in Python3 of email handling of unicode strings in headers


New submission from R. David Murray rdmur...@bitdance.com:

In Python2, this works:

 from email.mime.text import MIMEText
 m = MIMEText('abc')
 str(m)
'From nobody Tue Mar 13 15:44:59 2012\nContent-Type: text/plain; 
charset=us-ascii\nMIME-Version: 1.0\nContent-Transfer-Encoding: 7bit\n\nabc'
 m['Subject'] = u'É test'
 str(m)
'From nobody Tue Mar 13 15:48:11 2012\nContent-Type: text/plain; 
charset=us-ascii\nMIME-Version: 1.0\nContent-Transfer-Encoding: 
7bit\nSubject: =?utf-8?q?=C3=89_test?=\n\nabc'

That is, unicode string automatically get turned into encoded words.
In Python3 this no longer works:

 from email.mime.text import MIMEText
 m = MIMEText('abc')
 str(m)
'Content-Type: text/plain; charset=us-ascii\nMIME-Version: 
1.0\nContent-Transfer-Encoding: 7bit\n\nabc'
 m['Subject'] = u'É test'
 str(m)
Traceback (most recent call last):
  File stdin, line 1, in module

self.append(s, charset, errors)

s.encode(output_charset, errors)
UnicodeEncodeError: 'ascii' codec can't encode character '\xc9' in position 
0: ordinal not in range(128)

Presumably the problem is that the Python2 code tests for 'string' and if
it isn't string handles it by CTE encoding it.  In Python3 everything
is a string.  Probably what should happen is the encoding error should
be caught, and the CTE encoding done at that point, based on the model of how 
Python2 handled unicode strings.

[issue14062] UTF-8 Email Subject problem


R. David Murray rdmur...@bitdance.com added the comment:

It makes no sense that changing how Subject is generated would affect the later 
formatting of the mime header.  There is no coupling that I'm aware of in the 
code.

I notice that your handcrafted version uses uppercase for the charset and CTE 
code.  Can you try using lowercase like the email module does, and see if that 
reproduces the problem?

[issue829370] math.signum(int)

2012-03-13 Thread Frank


Frank frank.breitl...@gmx.de added the comment:

Mark, the convincing use-cases apear already on this page.

People suggest the usage of numpy or the definition of all kinds of functions 
to accomplish this trivial task. But the users don't want to worry about this. 
They just want to use this function and not lose time figuring out how to best 
implement it in python.

Copysign is not very intuitive e.g. because command completion on math.si_ 
fails and because it will not be a first result by search engines.

The discussion is another example for the user request. And I have the feeling 
that with the time spend on it all different variations of signum functions 
could have been implemented including their documentation - although the 
implementation of your two line solution should have been satisfying for almost 
everybody...
