[issue24429] msvcrt error when embedded
New submission from erik flister:
normally, CDLL(find_library('c')) is fine. but when running embedded in a
context that uses a different runtime version, this will cause an error
(example:
http://stackoverflow.com/questions/30771380/how-use-ctypes-with-msvc-dll-from-within-matlab-on-windows/).
using ctypes.cdll.msvcrt apparently finds the correct runtime. i was surprised
by this, i thought this was supposed to be identical to find_library('c').
in any case, some libraries (uuid.py) use the one that breaks. can you either
switch everything to ctypes.cdll.msvcrt, or have find_library('c') change to be
identical to it?

The problem is that there are two different ways repr might write out

it's why doctest fails badly at examples involving dictionaries. Text
format protocol buffers output everything sorted, so that you can do
textual diffs for compatibility tests and such.
With Python's JSON module [1], you can pass sort_keys=True to
stipulate that the keys be lexically ordered, which should make the
output canonical. Pike's Standards.JSON.encode() [2] can take a flag
value to canonicalize the output, which currently has the same effect
(sort mappings by their indices). I did a quick check for Ruby and
didn't find anything in its standard library JSON module, but knowing
Ruby, it'll be available somewhere in a gem.
AFAIK Ruby's dicts are ordered. So the output is pretty stable.

Re: Parser needed.
Well it did help a little bit. Somebody asked if there was already a parser for it. I answered yes in C#. So I took a closer look at it... and learned something from it. Maybe I would have done that anyway... or maybe not... Now we will never know... but I am happy that the parser is now ok, done and pretty easy extendable. I think it's probably my first really good one. I did do a little assembler before... but not sure if it was any good. I also read before I started the thread... what parse means in dictionary. That also helped me understand it a little bit better. And also I read how it's usually done... tokens/tokenize etc... kinda already knew that... but still. Turned out to be quite easy... But at the start /always it seemed so difficult... So any little bits of help/advice/information can help ! :) Bye, Skybuck. -- https://mail.python.org/mailman/listinfo/python-list

You're iterating over the keys. What you want is to iterate over
fields.items() which gives the key/value pairs.

Dicts are unordered. Try 'OrderedDict' from the 'collections' module.

Except that you already have written OO code in Python with your parser. Or at least code that interacts heavily with OO. Anytime you call a method on a string like split(), or worked with regular expressions, you are using OO. OO permeates Python. You don't have to use OO design in your programs, but you will always be working with objects and calling methods on them. But anyway, if you don't like self, use a different name. Like skybuck. class Bar: def foo(skybuck, a, b): skybuck.a = a skybuck.b = b In other languages with an implicit self or this like C, I find the ambiguities of scope highly problematic. Method variables can shadow instance variables. It's also difficult for someone unfamiliar with the code to differentiate between a local variable and an instance variable as the naked variable name has no qualifier. I've seen some projects that apply a m_ prefix to every instance variable so you can tell them apart. Sure that's less typing, but it is super ugly! Explicitly providing self not only makes things very clear, it also helps me when I'm scrolling through code to identify which functions definitions are bare functions and which are methods of a class. In short, it's part of the Python language and will not be changing anytime soon. So no the interpreter couldn't be written in such a way that the self can be left out without changing the language's semantics and definition. -- https://mail.python.org/mailman/listinfo/python-list

[issue24434] ItemsView.__contains__ does not mimic dict_items
New submission from Caleb Levy: The current implementation ItemsView.__contains__ reads class ItemsView(MappingView, Set): ... def __contains__(self, item): key, value = item try: v = self._mapping[key] except KeyError: return False else: return v == value ... This poses several problems. First, any non-iterable or iterable not having exactly two elements will raise an error instead of returning false. Second, an ItemsView object is roughly the same as a set of tuple-pairs hashed by the first element. Thus, for example, [a, 1] in d.items() will return False for any dict d, yet in the current ItemsView implementation, this is True. The patch changes behavior to immediately return false for non-tuple items and tuples not of length 2, avoiding unnecessary exceptions. It also adds tests to collections which fail under the old behavior and pass with the update. -- keywords: +patch Added file: http://bugs.python.org/file39682/ItemsView_contains.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24434 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24429] msvcrt error when embedded
Steve Dower added the comment: Python needs to be recompiled to use a different CRT, and that will break all existing extension modules (.pyd's). That said, in some situations it is the right answer, typically because existing extension modules would be broken anyway, but I don't think that applies here. To load msvcr90.dll, you need to declare in your executable which version you want to use using a manifest. This enables side-by-side use of the CRT, so different programs can use different versions and they are all managed by the operating system (for security fixes, etc.). Otherwise, you get hundreds of copies of the CRT and they are likely to be lacking the latest patches. A way to hack in the manifest is to put it alongside the executable. You could take the file from http://stackoverflow.com/questions/27389227/how-do-i-load-a-c-dll-from-the-sxs-in-python/27392347#27392347 and put it alongside the MATLAB executable as matlab.exe.manifest or whatever, which avoids having to get Mathworks involved, and that might allow you to load msvcr90.dll. If they've already embedded a manifest into the executable (which is very likely), then I don't know which one will win or what effects may occur if the original one is ignored. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24429 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24429] msvcrt error when embedded
Steve Dower added the comment: python.exe already has the manifest it needs, but it can't be embedded into python27.dll - it has to go into the exe file. That's why Python can't make it so that msvcr90.dll is loaded. Depending on what you're using it for, the C Runtime may keep some state in between function calls. For things like string copying (with no locale) you'll be okay, but most of the complication stuff assumes that every call into the CRT is calling into the *same* CRT. When you load different CRTs at the same time (as is happening here already, or when you load mscvrt.dll directly), you have to be very careful not to intermix them together at all. The most obvious example is open file handles. If you open a file with CRT 9.0 (msvcr90.dll) and then try and read from it with CRT 6.0 (msvcrt.dll), you'll probably crash or at least corrupt something. The same goes for memory allocations - if CRT 9.0 does a malloc() and then CRT 10.0 does the free(), you're almost certainly going to corrupt something because they are not compatible. I suspect Mathworks is relying on people installing Python themselves so they don't have to redistribute it as part of MATLAB, which is totally fine, but you have to be prepared to deal with this situation. If they make their own build, they need to distribute it themselves (easy) and explain to people why numpy doesn't work anymore unless you use their special build of numpy too (ie. because it uses a different CRT). Like I said initially, we would probably accept a patch for uuid.py to skip the CRT scan on Windows, and similar changes like that where appropriate. If you need to be able to load the DLL yourself, you either need to carefully consider how the functions you call may interact with other implementations/versions that may be loaded, or set up the manifest so you can load msvcr90.dll. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24429 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15745] Numerous utime ns tests fail on FreeBSD w/ ZFS (update: and NetBSD w/ FFS, Solaris w/ UFS)
STINNER Victor added the comment: The resolution of os.utime()+os.stat() depends on two things: - resolution of the timestamp on the filesystem used to run test_os (where TESTFN is written) - resolution of the C internal function used by os.utime() os.utime() can have a resolution of 1 ns (ex: it's usually the case on Linux), whereas the FAT filesystem has as resolution of 2 seconds. os.utime() can have a resolution of 1 us (ex: FreeBSD) whereas the ZFS filesystem has a resolution of 1 ns. Currently, test_os.test_*utime*_ns checks that os.utime() is able to copy the timestamp of a file 1 to a file 2. Problem: we don't know the resolution of the timestamp of the file 2. We can get the resolution of the C internal function used by os.utime(). It is implemented in the attached test_os.patch. But it's much more complex to get the timestamp resolution of the filesystem, in a portable way. Random thoughts: * use a timestamp with a resolution of 1 us, smaller than 2^24 to avoid rounding issues.

STINNER Victor added the comment: test_utime_ns.patch: rewrite _test_utime_ns(). It now uses constant timestamps for atime and mtime with a resolution of 1 us. The test will fail if the internal function of os.utime() has a resolution of 1 sec (utime() with time_t) of if the resolution of filesystem timestamp is worse than 1 us. In practice on buildbots, it looks like the effective resolution of 1 us (FreeBSD, Solaris), 100 ns (Windows) or 1 ns (Linux). So 1 us should work on all buildbot slaves. test_utime_ns.patch doesn't call os.utime() on directories, only on a regular file. I don't understand the purpose of testing with a directory.

[issue24434] ItemsView.__contains__ does not mimic dict_items
Caleb Levy added the comment:
@serhiy.storchaka: I don't think that will work.
First of all,
x, y = item
will raise a ValueError if fed an iterable whose length is not exactly 2, so
you would have to check for that. Moreover, if item is something like a dict,
for example, then:
{a: 1, b: 2} in DictLikeMapping(a=b)
could return True, which I don't think would be expected behavior.
I'm not terribly fond of the instance check myself, but in this case I can't
see any other way to do it: the built in dict_items necessarily consists of
*tuples* of key-value pairs.

It might allow you to easily implement doctype() in both the old and new versions of the API, without worrying about the API being called twice, and without experiencing any DeprecationWarning. But I do not have a real-world use case to demonstrate this, and I don’t think this decision should hold up committing inherit-doctype.v2.patch. They are separate bugs. BTW: Another difference between the implementations is that the C version accepts my !DOCTYPE blaua test case, but the Python version ignores it.

Changes: * Use a fixed timestamp instead of copying timestamps from an existing file. If the timestamp of the original file can have a resolution of 1 nanosecond, os.utime() rounds to a resolution of 1 us on some platforms (when the C function uses a structure with a resolutionf of 1 us). * Use a fixed timestamp with a resolution of 1 us instead of a resolution of 1 ms. * Remove test_1565150(): it's now redundant with test_utime() and many other test_utime_*() tests * Use self.fname instead of __file__ to check if the filesystem supports subsecond resolution: these two files may be in two different filesystems * test_large_time() now checks the filesystem when it is executed, not when the class is defined. This change is to ensure that we are testing the right filesystem. * replace support.TESTFN with self.dirname for readability * move all os.utime() tests in a new dedicated class * _test_utime_current() now get the system clock using time.time() and tolerate a delta of 10 ms instead of 10 seconds: we may increase the delta because of slow buildbots, but I hope that we can find a value smaller than 10 seconds! * Avoid tricky getattr(), it's no more needed * Merge duplicated test_utime_*() and test_utime_subsecond_*() functions * Test also st_atime on when testing os.utime() on a directory * etc. -- Added file: http://bugs.python.org/file39689/test_utime.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15745 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Apology for any indentation error.
Regards,
Subhabrata Banerjee.

Instructions here should help. https://docs.python.org/2.7/using/windows.html It is possible that you need to do some other things too, but again that's the doc for it. Laura -- https://mail.python.org/mailman/listinfo/python-list It’s actually %PATH%. %PYTHONPATH% does something different and is not really useful to newcomers (especially since there are much better ways to accomplish what it does) -- Chris Warrick https://chriswarrick.com/ PGP: 5EAAEA16 Sorry about that -- what you get for not using windows. Thank you. Laura -- https://mail.python.org/mailman/listinfo/python-list
