[issue16613] ChainMap.new_child could use improvement
New submission from Vinay Sajip:
ChainMap.new_child could IMO be improved through allowing an optional dict to
be passed, which is used to create the child. The use case is that you
sometimes need to temporarily push a new non-empty mapping in front of an
existing chain. This could be achieved by changing new_child to the following,
which is backwards-compatible:
def new_child(self, d=None):
'New ChainMap with a new dict followed by all previous maps.'
return self.__class__(d or {}, *self.maps)

[issue1209447] os.path.join() fails if 2nd arg is a UNC path
Pekka Klärck added the comment:
It seems that joining UNC path to a directory root fails:
Python 2.7.3 (default, Sep 26 2012, 21:51:14)
[GCC 4.7.2] on linux2
Type help, copyright, credits or license for more information.
from ntpath import join
join('c:\\', 'server\\mount\\dir')
'c:server\\mount\\dir'
When the first argument contains also something else everything works fine:
join('c:\\dir', 'server\\mount\\dir')
'server\\mount\\dir'
I would say this is a bug. Obviously fixing this changes behavior, but I have
hard time believing that anyone relies on the current buggy output.
On the other hand, I was today reported a bug in my software that was caused by
this. Funny thing was that the bug was in code that was added as a workaround
for issue #3426 (i.e. use `join(os.getcwdu(), path)` instead of `abspath(path)`
when path is Unicode). Luckily adding another workaround for this issue is
pretty easy.

[issue13044] pdb throws AttributeError at end of debugging session
Xavier de Gaye added the comment:
On finalizing pdb can stop working at some time, but debugging on
finalization stage can be still useful in certain cases.
Agreed that debugging on finalization stage is useful. Debugging on
finalization stage does not seem to work though:
===
class C:
def __del__(self):
print('deleted')
c = C()
import pdb; pdb.set_trace()
x = 1
===
$ python3 bar.py
/tmp/bar.py(7)module()
- x = 1
(Pdb) step
--Return--
/tmp/bar.py(7)module()-None
- x = 1
(Pdb) step
deleted
$
===
Maybe this is another issue.
Xavier, your proposition noticeably changes current behavior as I understand
it. For now set_trace() works as breakpoint set up by program, you can go
out of debugged function and it's very convenient from my perspective.
This proposition only sets the global trace function to None on
returning from the bottom frame, i.e. the oldest frame in the stack. So you can
still use set_trace() as a hard-coded breakpoint and continue the debugging
session out of the debugged function.

[issue13968] Support recursive globs
Serhiy Storchaka added the comment: Here is a patch which implements recursive globbing which conforms to Bash globbing with globstar option. For backward compatibility recursive globbing off by default and works only if new argument recursive is true (default is False). I am not sure this is a better variant. Possible the default should be True. '**' pattern is very unlikely in old code. However recursive globbing on arbitrary pattern and arbitrary tree is not safe, it can hang on recursive symlinks.

[issue16619] LOAD_GLOBAL used to load `None` under certain circumstances
New submission from Bruno Dupuis:
We found some strange behaviour of the compiler in this discussion on
python-list:
http://mail.python.org/pipermail/python-list/2012-December/636104.html
The fact is, `return` and `return None` result in inconsistent bytecode
depending on the context.
Consider :
import dis
def f(x):
... return None
...
dis.dis(f)
2 0 LOAD_CONST 0 (None)
3 RETURN_VALUE
def g(x):
... return None
... print(x)
...
dis.dis(g)
2 0 LOAD_GLOBAL 0 (None)
3 RETURN_VALUE
3 4 LOAD_GLOBAL 1 (print)
7 LOAD_FAST0 (x)
10 CALL_FUNCTION1 (1 positional, 0 keyword pair)
13 POP_TOP
`return None` statement results in LOAD_GLOBAL 0 if there is some unreachable
code after it. I first saw that as an optimization issue, but Ian Kelly's
message http://mail.python.org/pipermail/python-list/2012-December/636117.html
gives an extensive analysis and some examples:
I think this should even be considered a bug, not just a missing
optimization. Consider:
globals()['None'] = 42
def f(x):
... return None
... print(x)
...
f('test')
42
The use of the LOAD_GLOBAL allows None to effectively be reassigned.
Ian also points out in this message that `return` and `return None` don't
result in the same bytecode when followed by trash code.

[issue16621] sched module enhancement request
New submission from Carlos Ferreira: The sched module available in the Python core lacks a simple but very useful which is waiting for new events scheduling. Current version only process events that are present in the queue before the schedule.run() is issued or for events that are schedule while the scheduler is still active and processing events from the queue. I propose a simple enhancement, by using an Event object from the threading module, so that the thread that is running the scheduler, waits for new events scheduling, after finishing processing all queued events. The sched2.py is a modified version of the original sched.py (modified by means of a large hammer), which adds an alwaysRunning argument in the object constructor, a self.wakeUpEvent attribute which is the Event Object, a modified eterabs method to call the Event.set() and finally, a modified run() to wait for new events. This modification is just a quick patch in order to pass the idea of what is being requested here. If there is a better way to do this, then it should be taken. -- components: Library (Lib) files: sched2.py messages: 177002 nosy: carlosmf.pt priority: normal severity: normal status: open title: sched module enhancement request type: enhancement versions: Python 3.3 Added file: http://bugs.python.org/file28214/sched2.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16621 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Bruno Dupuis added the comment: This first patch spots the issue, but doesn't solve it if the bytecode of the function is 32700 (see PyCode_Optimize comment). However with this patch, we get the LOAD_CONST anytime for None, True and False. There is two questions : 1- is it safe to strip all the code after RETURN_VALUE as the patch does? 2- to correct this bug, we will need a deep refactoring of PyCode_Optimize (so that it accepts any code length). The other way, is not to rely on PyCode_Optimize to compile return None/True/False, but do modifictations in the compiler itself. This must be the right way to do this, but it's far beyond my C skills and python core knowledge. -- keywords: +patch Added file: http://bugs.python.org/file28217/16619-1.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16619 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16619] LOAD_GLOBAL used to load `None` under certain circumstances
Terry J. Reedy added the comment: (2.6 is security fix only) Stripping truly dead code after return is really tricky in general because a) it might be in a conditional block, and b) unreachable yield and assignment can affect compilation. Assignments that make names local are detected on a first pass, but I do not know about yield. Anyway, I believe the policy has been to not do it. The final patch will need a cpython-only test based on g(x), with dead code. Possibly intersecting issues are proposals to change where optimization is done and, for testing, to add a generator to dis so its output can be directly captured and analyzed instead of having to redirect, capture, and parse stdout. -- nosy: +benjamin.peterson, brett.cannon, georg.brandl, ncoghlan, terry.reedy stage: - patch review type: - behavior versions: -Python 2.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16619 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16619] LOAD_GLOBAL used to load `None` under certain circumstances
Nick Coghlan added the comment: First reaction is +1 for finally switching to real constant nodes in the AST for 3.4+. This is an inherited behaviour from 2.x where these were ordinary names rather than true keywords, so we weren't able to completely disallow overwriting them. As a smaller impact change for earlier versions, we should be able to do something in compiler_nameop [1] that picks up the 3 singleton names and allows only LOAD_CONST, erroring out otherwise. http://hg.python.org/cpython/file/default/Python/compile.c#l2625 -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16619 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16625] Exception on mode 'br'
New submission from Sworddragon: The mode 'br' on open() can cause an exception with the following message: ValueError: mode string must begin with one of 'r', 'w', 'a' or 'U', not 'br'.

[issue15207] mimetypes.read_windows_registry() uses the wrong regkey, creates wrong mappings
Ben Hoyt added the comment: Ah, thanks for making this an issue of its own! As I commented over at Issue10551, it's a serious problem, and makes mimetypes.guess_type() unusable out of the box on Windows. Yes, the fix in Issue4969 uses MIME\Database\Content Type, which is a mime type - file extension mapping, *not the other way around*. So while this patch is definitely an improvement (for the most part it doesn't produce wrong values!), but I'm not sure it's the way to go, for a few reasons: 1) Many of the most important keys aren't in the Windows registry (in HKEY_CLASSES_ROOT, where this patch looks). This includes .png, .jpg, and .gif. All of these important types fall back to the hard-coded types_map in mimetypes.py anyway. 2) Some that do exist are wrong in the registry (or at the least, different from the built-in types_map). This includes .zip, which is application/x-zip-compressed (at least in my registry) but should be application/zip. 3) It's slowish, as it has to load about 6000 registry keys (and more as you install more stuff on your system), but only about 200 of those have the Content Type subkey. On my machine (Windows 7, 64 bit CPython) this adds over 100ms to the startup time even on subsequent runs when cached -- and I think 100ms is pretty significant. Issue4969's version takes about 25ms, and reverting this completely would of course take 0ms. 4) Users and other programs can (and sometimes do!) change the Content Type keys in the registry -- whereas one wants mime type mappings to be consistent across systems. This last point is debatable for various reasons, and I think the above three points should carry the day, but I include it here for completeness. ;-) For these reasons, I think we should revert the fix for Issue4969 and leave Windows users to get the default types_map as before, which is at least consisent -- and for mimetypes.guess_type(), you want consistency. -- nosy: +benhoyt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15207 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
