[issue24844] Python 3.5rc1 compilation error with Apple clang 4.2 included with Xcode 4
Ned Deily added the comment: This is a regression from previous releases of Python. It was introduced by fbe87fb071a6 (for Issue22038) which added the use of C built-in functions for atomic memory access for additional architectures like x86_64. It seems that the relatively early version of Apple's clang included with Xcode 4 fails compiling this code. The specific clang version that failed (Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)) is the version included with the last shipped version of Xcode 4, Xcode 4.6.3, for OS X 10.7 and 10.8. For OS X 10.8, there is available a more recent version of Xcode, Xcode 5.1.1, which includes a new version of clang, Apple LLVM 5.1 (clang-503.0.40), which does correctly compile this code. In general, we always recommend using the most recent available version of Xcode- or Command Line Tools-installed build tools for a particular version of OS X (with the notable exception of OS X 10.6 - stick with Xcode 3.2.6 there). So upgrading to Xcode 5.1.1 on OS X 10.8.5 should solve the problem there. Unfortunately, for OS X 10.7.x, Xcode 4.6.3 is the most recent version and Xcode 4 has always been somewhat problematic for Python builds. It was in Xcode 4 that Apple stopped shipping the native gcc-4.2 compiler in favor of clang and the hybrid Apple llvm-gcc-4.2 compiler (which uses gcc as the front end and LLVM as the backend). The llvm-gcc-4.2 compiler was a transitional tool, not well-maintained, and is known to incorrectly compile recent versions of Python 3 (Issue13241) so it cannot be used as a substitute for clang in this case on OS X 10.7 (it was no longer shipped as of Xcode 5). Support for OS X 10.8 is much more important than OS X 10.7: I doubt there are *that* many users are still on 10.7. So I think a case could be made for marking this as won't fix. On the other hand, it should be possible to add tests to ./configure to skip trying to use the atomic builtins when this compiler is in use. -- nosy: +haypo, larry title: Python 3.5rc1 compilation error on OS X 10.8 - Python 3.5rc1 compilation error with Apple clang 4.2 included with Xcode 4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24844 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12892] UTF-16 and UTF-32 codecs should reject (lone) surrogates
Serhiy Storchaka added the comment: There are two causes: 1. UTF-16 and UTF-32 are based on 2- and 4-bytes units. If the surrogateescape error handler will support UTF-16 and UTF-32, encoding could produce the data that can't be decoded back correctly. For example '\udcac \udcac' - b'\xac\x20\x00\xac' - '\u20ac\uac20' == '€가'. 2. ASCII bytes (0x00-0x80) can't be escaped with surrogateescape. UTF-16 and UTF-32 data can contain illegal ASCII bytes (b'\xD8\x00' in UTF-16-BE, b'abcd' in UTF-32). For the same reason surrogateescape is not compatible with UTF-7 and CP037. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12892 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

In a message of Mon, 10 Aug 2015 15:43:26 -0500, E.D.G. writes: I needed a program that could generate data regarding the locations of the sun and the moon in the sky in response to specific times entered. Roger developed the basic equations with some help from another researcher. And that took a while. But it probably took a full six months for us to compare notes by E-mail and get the program into a final form that people could download for free use. I see a pattern here. You and Roger keep coming up with cool ideas, but neglect to check if _somebody else already had them_ and if we already have a Python package that does what you want to do. We've got, for instance, PyEphem http://rhodesmill.org/pyephem/tutorial.html and if that doesn't already do what you want, well there are other choices that astronomers are using all the time, right now. Wrapping a giu around PyEphem, if that is what you want is a job that can be measured in hours or days if you are a proficient Python programmer. That is just too much time. Researchers need to be able to do things such as create simple charts etc. without spending months or years learning some programming language or comparing notes with one another. So, an entire Python directory that made that possible and that had clear instructions for how to open and close files and create pipes etc. would get the job done. We've already got this with the Scientific Python distribution. For more than 20 years, thousands, tens of thousands of scientist-python programmers have been beavering away writing solutions to the problems you mention and others that are, as you say, deeply important to them. I am sorry that you came to this party late, but the good news is that you should be able to get what you want with a whole lot less work than you think. What you need to do is familiarise yourself with what we already got, instead of assuming that because you don't know about them, they don't exist. One of the ways to do this is to join scientific python mailing lists. **This list isn't one of them.** Scientists who use Python mostly _do not hang out here_. I'd join Scipy-Users: http://www.scipy.org/scipylib/mailing-lists.html or hang out on the freenode irc channel #scipy and tell the people both places that you are new to python and are looking for an overview of what there is out there. Maybe post the same thing to the Anaconda Google group. https://groups.google.com/a/continuum.io/forum/?fromgroups#!forum/anaconda The scientists in all of these places are going to give you better answers for how to familiarise yourself with their ecosystem than I can -- they _live_ there, and I just vist sometimes. If Roger wants to use Python then we might use the ActiveState version and then build those various resources into it. It reportedly installs in a Windows environment without problems. And I myself have used the ActiveState versions of Perl for quite a few years with a considerable amount of success. If you want to write more tutorials about how to use the various Python resources we already have, then more power to you, we always need more of that. But if you plan on redoing stuff we already have a way to do, then you are likely to be ignored. The usual thing to do is to join some existing Python project, and contribute your ideas and code to it. So, since you are interested in graphics you might join the matplotlib group. Or you might join the bokeh group. It's not impossible to start your own project -- the bokeh people did, after all, but this pretty much only works if you address a real problem that isn't being met by the existing libraries. For instance, the bokeh people wanted to make an interactive visualisation library that targets modern web browsers. It sounds like you are interested in that as well, but the bokeh people are way, way, way ahead of you in that business. There are more of them, and they have been writing code to improve how they do things every day now since 2012 (at least that what their license says). So you aren't going to catch them with your new project. If it turns out they are unable to do something that you need, the thing to do is to join the project and help them by implementing that stuff so it can be added to the library. This assumes that the ActiveState version of Python can be taught to do fast calculations and to generate charts. If that does not look possible or easy then we will probably try one of the available scientific versions of Python. You are misunderstanding something here. You don't need to teach ActiveState Python to do fast calculations and generate charts. Somebody already has done this, in a variety of ways, some of which have worked for more than a decade, I think more than 15 years now. And that is where numpy comes in -- this is one of the ways to teach Python to do faster calculations. So is Cython. So is Numba. The reason you would go for a

[issue24840] implement bool conversion for enums to prevent odd edge case
Mike Lundy added the comment: @serhiy.storchaka: It's somewhat of a special case, to be sure. However, I do think it's justified to put it into the base (rather than a user type) for three reasons: 1) It makes IntEnum and Enum consistent. IntEnum actually already handles this case just fine, because it's an int and therefore already supports __bool__ correctly. It feels odd that changing the storage format from an IntEnum to a Enum should break the logic- correctly used, the actual enum values should never matter. This small change just brings them into line. 2) It is less surprising than the current case; I discovered this when I did something like the Enum.Nope case here, and I naively used the enum in an if statement, assuming that the value would control the __bool__ value. (This was caught by my tests, of course, but the point remains that I wrote the code). Normally in python, you'd expect the default bool conversion to be unconditionally True, but enums aren't really normal objects; for any use case for which there is a default noop value, you'd generally put that value _into_ the enum: class FilterType(Enum): NONE = None SUB = 'Sub' UP = 'Up' ... 3) It's not logically inconsistent with the idea of Enums. The other dunder methods you mention aren't consistent with the concept: __float__ (enum values aren't generally numbers except as an implementation detail), __lt__ (enums aren't generally ordered), __len__ (enums aren't generally containers). The one thing an enum does have is a value, and it feels consistent to me to check the truthiness of an enum without having to reach into the .value to do so. Anyway, that's my case for inclusion! -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24840 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue9232] Allow trailing comma in any function argument list.
Adam Bartoš added the comment: Some remarks: • A trailing comma after a non-empty argument list is allowed in every call form, including class statement and optional call in decorator syntax. In the grammar, this correponds to `arglist`. • In function definition, trailing comma is allowed only if there is no star before: def f(a, b, c,): # allowed def f(a=1, b=2, c=3,): # allowed def f(*args,): # disallowed def f(**kwargs,): # disallowed def f(*, a, b, c,): # disallowed The last example is what bothers me. The presence of the star should not affect whether trailing comma is allowed or not. If `f(a, b, c,)` is allowed as a call, it should be allowed in a definition, and if def `f(a, b, c,)` is allowed, `f(*, a, b, c,)` should be allowed as well. In the grammar this corresponds to `typedargslist` for functions and `varargslist` for lambdas. • A traling comma is allowed in tuples, lists, dicts, sets, the corresponding comprehensions, augmented assignments, and subscripts. It is also allowed in `from module import names` in the names part, but only if there are surrounding parentheses. Also a trailing semicolon is allowed for multiple statements in one line. • A traling comma is *not* allowed in with statement, `import modules`, assert statement (there is just optional second argument), global and nonlocal statements. In all these cases surrounding parentheses are not allowed. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9232 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12892] UTF-16 and UTF-32 codecs should reject (lone) surrogates
tmp12342 added the comment: Serhiy, I understand the first reason, but https://docs.python.org/3/library/codecs.html says applicable to text encodings: [...] This code will then be turned back into the same byte when the 'surrogateescape' error handler is used when encoding the data. Shouldn't it be corrected? Text encoding is defined as A codec which encodes Unicode strings to bytes. And about second one, could you explain a bit more? I mean, I don't know how to interpret it. You say b'\xD8\x00' are invalid ASCII bytes, but from these two only 0xD8 is invalid. Also, we are talking about encoding here, str - bytes, so who cares are resulting bytes ASCII compatible or not? -- nosy: +tmp12342 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12892 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Re: looking for standard/builtin dict-like data object
I also thought the stdlib had some kind of namespace class with this kind of API, but I can't find it now:-( It does - types.SimpleNamespace(). It accepts keyword arguments, and will let you create more attributes on the fly (unlike a namedtuple). Yes, that's it. Thanks! Ah, sad, sad, sad. We unfortunately stuck with built-in Python 2.6.x in our system. I see from docs that SimpleNamespace is rather new creation (3.3+). I know 'namedtuple' way, but don't like it as I prefer freedom in attribute creation/mutation. Looks like I have to stuck with handmade solution for now. Anyway - thanks a lot for everybody!

Data integrity problem with sqlite3
Hi all I have a 'data integrity' problem with sqlite3 that I have been battling with for a while. I have not got to the bottom of it yet but I do have some useful info, so I thought I would post it here in the hope that someone with some knowledge of the internals of the python sqlite3 module can throw some light on it. I am running python 3.4.3 on Windows 7, and I have upgraded sqlite from the original '3.7.something' to '3.8.6'. I do not change the isolation level from the default setting. I have a transaction with a number of steps. One of the later steps raises an exception, and I execute a rollback. However, some of the earlier steps are committed to the database. Obviously this is a major problem. I have added 'set_trace_callback' to see exactly what is going on, and in the middle of my series of commands I find the following - COMMIT BEGIN IMMEDIATE According to the docs, the sqlite3 module commits transactions implicitly before a non-DML, non-query statement (i. e. anything other than SELECT/INSERT/UPDATE/DELETE/REPLACE). In my traceback I can only see SELECTs and UPDATEs following the implicit commit, so I do not know what is triggering it. I am trying to reproduce the problem in a simpler example, but so far without success. My running program has two connections to the database open, another connection to an in-memory database, and it is all running under asyncio, so it is quite difficult to mimic all of this. I will persevere, but in the meantime, does anyone happen to know under what other circumstances sqlite3 might issue an implicit commit?

[issue21167] float('nan') returns 0.0 on Python compiled with icc
Chris Hogan added the comment: Producing NaN by Py_HUGE_VAL / Py_HUGE_VAL as in the suggested patch is unsafe as it can generate a FP exception during runtime. Also aggresive compiler FP optimizations can eliminate this calculation on compile-time. For this reason, we've used constant referencing in our fix, which will work regardless of how -fp-model is set. The problem is that the compiler is free to pre-compute the result as both values in 0*Inf are constants. An aggressively optimizing compiler could treat 0 * x = 0 no matter what x is. So under aggressive floating point optimizations setting we could get a wrong value, and that is indeed what happens. Another problem is that 0 * Inf along with resulting in a QNaN value should raise an invalid floating point exception flag. If the result is pre-computed at compile time, then the user won’t see the flag (it is another question whether the user wanted the flag or not originally). Our patch preserves both the value and the side effect, and leaves people free to build with the flags they want. -- nosy: +christopher.hogan Added file: http://bugs.python.org/file40162/intel-nan-safe.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21167 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Steve, when you say you fixed this for 3.5, does that means there's a simple command or API to revert this automatic ProgId back to the Python.File type? This problem shows up repeatedly on Stack Overflow, so it would be nice to have a solution that works consistently from Windows 7 to 10. cmd.exe's built-in assoc and ftype commands only modify the local machine association and filetype. A per-user install doesn't use those, and sometimes Explorer instead uses a per-executable command defined in Software\Classes\Applications. Also, just modifying the command doesn't actually select what ShellExecuteEx will choose to run. I used to directly modify Explorer's FileExts\...\UserChoice for a given file extension, but that's actively discouraged by a deny ACL nowadays. Fine, but I've run into cases where Explorer's dialog doesn't let me choose a an existing ProgId. -- assignee: - steve.dower resolution: not a bug - status: closed - open versions: +Python 3.5, Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24843 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Re: pyjs - a compiler from Python to JavaScript
Thanks Fabio, we'll check RapydScript and we might use it for Speedy Mail Software as well! I will check with the other developers (which are on the speedy-mail-software list). In the past I had Speedy Mail online from 2000 to 2005 and it was based on a Perl script (Perl was popular in 2000). But since it didn't support Unicode/UTF-8 encoding and didn't have a spam filter I decided to close it in 2005 (after Google introduced Gmail). But I think today it's easier to create software than it was in 2005, and I hope next year we can launch Speedy Mail again, based on the Speedy Mail Software we are developing (which will be free software open source). I'm looking forward to launching Speedy Mail as an alternative to Gmail. *Uri Even-Chen* [image: photo] Phone: +972-54-3995700 Email: u...@speedy.net Website: http://www.speedysoftware.com/uri/en/ http://www.facebook.com/urievenchen http://plus.google.com/+urievenchen http://www.linkedin.com/in/urievenchen http://twitter.com/urievenchen Speedypedia in Hebrew and English http://www.speedysoftware.com/uri/blog/speedypedia-in-hebrew-and-english/ On Tue, Aug 11, 2015 at 10:08 PM, Fabio Zadrozny fabi...@gmail.com wrote: Hi Uri, No, I'm not related to it. -- I'm the PyDev/Eclipse maintainer... that already takes a lot of my time ;) It's license is BSD (so, no need to pay).

There's quite a bit of MSBuild magic involved here though - I have trouble getting good reviews of this kind of change at work :( For whoever is looking - the InstallFiles items are processed by getting all the Included files, stripping SourceBase off the start and replacing it with Source (so a nop in this case) and including that file in the installer. The file is installed into Target (which is actually a directory reference into the installer, but DLLs is as self-explanatory as it seems) plus the relative path from TargetBase to the original filename. In this case, the old TargetBase was too short and so the file was installed with the last directory segment; after the fix the last directory segment is excluded. (Yes, the Source and SourceBase changes aren't really necessary, but changing them to match will avoid unnecessary questions in the future.) I should really add more documentation about this... Tools/msi/readme.txt has a bit, but not at this level. -- nosy: +paul.moore, tim.golden, zach.ware stage: - commit review ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24847 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

You need to do just a little more work to extract the hour. I don't know what you think you'll achieve by sorting key/value pairs in reverse order. What you should be doing is sorting the keys (hours), although sorting the pairs of keys and values (i.e., the items) would have the same effect. Have a look at the 'sorted' function.

Steve Dower added the comment: Pull request for 3.5.0 is at https://bitbucket.org/larry/cpython350/pull-requests/3/issue-24847-fixes-tcltk-installer-layout/diff. When merged, this can change back to normal priority for the rest of the fix. Long term (probably 3.5.1, possibly 3.5.0rc2 if I can get it done) I want to build tcl/tk differently so we don't have the dependency on this unstable part of the VC runtime, but deploying it now is the easiest way to keep tcl/tk working. The biggest risk is that extension authors may plan to depend on it - currently distutils bdist_ext does not use it, but that is already causing compatibility issues with old code (a.k.a. code that needs updating for a newer compiler), so there'll be a bit of wait and see. Maybe we'll just have to accumulate all versions of vcruntime*.dll from now until forever (and backport them), but I hope we can avoid that. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24847 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Steve Dower added the comment: Yep, this is my fix for the same issue pre-RC1 not quite working out (I'm guessing some difference between my dev box and my build box). If you go into your DLLs directory there's an extra subdirectory (Microsoft.VC140.CRT or similar) with a single DLL in it. Move that DLL up one level to the DLLs folder and you should be fine. I'll work up a setup authoring fix immediately, but really I want to patch Tcl/tk to not rely on that DLL so that we can be truly independent of CRT versioning. -- assignee: - steve.dower nosy: +larry priority: normal - release blocker versions: +Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24847 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Steve Dower added the comment: Mark, IIRC you've got VS 2015? Anyone with VS 2015 installed (or the full CRT redistributable) is unaffected because the required file is already in their system path - this includes my build machine, which is why all my tkinter tests passed before pushing the release (currently figuring out a way to avoid this in future without needing extra machines). This is also why I'm worried about extensions built with non-distutils based tools. Anyone with the compiler has the current version of vcruntime.dll, but users may not (this is the versioning issue - someone might build with vcruntime150.dll which then won't work with vcruntime140.dll, so I'm trying to just block the DLL entirely). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24847 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
