[issue23546] windows, IDLE and pep 397
New submission from Liam Marsh: hello, pep 397 describes a Python launcher for the Windows platform. A Python launcher is a single executable which uses a number of heuristics to locate a Python executable and launch it with a specified command line. Problem: that affects only the open file action behavior, and not the EDIT with idle file action behavior, and then it is the last installed IDLE who wins. the problem is not the IDLE changes themselves, but that one version's IDLE can only run the edited script in its version, and ignoring the shebang. Could the windows installer install a third executable (for ex: pyi.exe) which launch the correct IDLE according to the shebang line of the edited file? Or maybe it should be done using pyw.exe /edit filepath... Than you for reading this and have a nice day/evening! -- components: IDLE, Windows messages: 236870 nosy: Liam.Marsh, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: windows, IDLE and pep 397 type: enhancement versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5, Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23546 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17576] PyNumber_Index() is not int-subclass friendly (or operator.index() docos lie)
Nick Coghlan added the comment: OK, something appears to have gotten confused along the way here. Barry's original problem report was that operator.index() was returning a different answer than operator.__index__() for int subclasses. Absolutely nothing to do with the int builtin at all. While the fact int() *may* return int subclasses isn't especially good, it's also a longstanding behaviour. The problem Barry reports, where a subclassing based proxy type isn't reverting to a normal integer when accessed via operator.index() despite defining __index__() to do exactly that should be possible to fix just by applying the stricter check specifically in PyNumber_Index. Expanding the scope to cover __int__() and __trunc__() as well would be much, much hairier, as those are much older interfaces, and used in a wider variety of situations. We specifically invented __index__() to stay away from that mess while making it possible to explicitly indicate that a type supports a lossless conversion to int rather than a potentially lossy one. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17576 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Likewise REXX has no reserved words; also, SQL went part-way there, with the notion of non-reserved keywords. For example, ORDER and BY are reserved keywords, so they are unavailable as table/column names, but NULLS is non-reserved. You could use it, if you wanted to, but it's a syntactic element in some contexts. You can say ORDER BY some_column NULLS FIRST or NULLS LAST to affect the ordering; you can even say ORDER BY NULLS NULLS FIRST, which will sort by a column named NULLS, in ascending order, but counting NULL as lower than everything (instead of higher than everything). Given the style of SQL, it'd be insanely restrictive if it had to have everything be either a keyword or nothing, so this is a good half-way-house.

Writing a Python implementation in C instantly makes Python available on all sorts of platforms, with direct access to native libraries on all of them. For example, CPython on Windows can make use of a whole bunch of Microsoft's win32 APIs, via the pywin32 extensions; meanwhile, CPython on Linux can use the inotify functions, again via an extension module (pyinotify or python-inotify). Jython doesn't offer that, as far as I know; or rather, Jython offers access to Java classes rather than to C libraries, and there are a lot more of the latter than the former.

Hi, For some scripts, I write in a a more functional way, using a lot of small functions outside of any class. Although it makes the code clearer for specific cases, I have found that it makes debugging and using the repl in general difficult, as as I have to re-initialise every single objects every time. I have now started to use some kind of state pattern to alleviate this, here's a simplistic example: https://github.com/dorfsmay/state_pattern_for_debugging_python/blob/master/dirstats.py Are there better ways to address this?

There is a problem with the patch. When you are in interactive help utility,
then the request 'help' runs nested interactive help utility. The difference
between unpatched behavior is that now you need press Ctrl-D or 'q' twice to
exit to normal Python interpreter. When you type 'help' repeatedly, your could
run third, fourth, etc nested help utility.
Here is modified patch. Now help('help') produces the same output as
help(help), but the 'help' request in interactive help utility prints help
intro message.

[issue23551] IDLE to provide menu options for using PIP
Terry J. Reedy added the comment: Raymond, I have had a very vague idea of doing something like this. Thanks for posting something more concrete. I share the sentiments of your last sentence. Reading Stackoverflow, it is apparent that some people with two+ Python versions do not know that a package must be installed for each version of Python, and have less idea how to install for the non-default version. (All I know is to cd to pythonxy, or maybe pythonxy/scripts and run pip from there, or something like that.) Running from Idle (x.y) would take of this. Donald: at Raymond's behest, Idle now has a menu entry to run turtledemo, a separate application that is useful to beginners, in part to make turtledemo more visible. pip_gui could easily follow the same model. No direct interaction with the Idle shell or edit windows is needed. If you are less familiar with tkinter than I am, I would help with the gui part. As hinted above, I am not the one to decide on menu options and write the implementation functions. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23551 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23553] Reduce the number of comparison for range checking.
New submission from Raymond Hettinger:
Python's core is full of bound checks like this one in Objects/listobject.c:
static PyObject *
list_item(PyListObject *a, Py_ssize_t i)
{
if (i 0 || i = Py_SIZE(a)) {
...
Abner Fog's high-level language optimization guide,
http://www.agner.org/optimize/optimizing_cpp.pdf in section 14.2 Bounds
Checking, shows a way to fold this into a single check:
-if (i 0 || i = Py_SIZE(a)) {
+if ((unsigned)i = (unsigned)(Py_SIZE(a))) {
if (indexerr == NULL) {
indexerr = PyUnicode_FromString(
list index out of range);
The old generated assembly code looks like this:
_list_item:
subq$8, %rsp
testq %rsi, %rsi
js L227
cmpq16(%rdi), %rsi
jl L228
L227:
... error reporting and exit ...
L228:
movq24(%rdi), %rax
movq(%rax,%rsi,8), %rax
addq$1, (%rax)
addq$8, %rsp
ret
The new disassembly looks like this:
_list_item:
cmpl%esi, 16(%rdi)
ja L227
... error reporting and exit ...
L227:
movq24(%rdi), %rax
movq(%rax,%rsi,8), %rax
addq$1, (%rax)
ret
Note, the new code not only saves a comparison/conditional-jump pair, it also
avoids the need to adjust %rsp on the way in and the way out for a net savings
of four instructions along the critical path.
When we have good branch prediction, the current approach is very low cost;
however, Abner Fog's recommendation is never more expensive, is sometimes
cheaper, saves a possible misprediction, and reduces the total code generated.
All in all, it is a net win.
I recommend we put in a macro of some sort so that this optimization gets
expressed exactly once in the code and so that it has a good clear name with an
explanation of what it does.

[issue23549] heapq docs should be more precise about how to access the smallest element
New submission from Eli Bendersky: The heapq documentation has this paragraph after the doc of nsmallest: The latter two functions perform best for smaller values of n. For larger values, it is more efficient to use the sorted() function. Also, when n==1, it is more efficient to use the built-in min() and max() functions. This is confusing as it suggests to use min() on a heap to find the minimal element. heap[0] is the minimal element, but this is only mentioned at the very top - so you need to read the doc of the entire module to find it. Nothing in the docs of methods suggests it. -- assignee: docs@python components: Documentation messages: 236895 nosy: docs@python, eli.bendersky priority: normal severity: normal status: open title: heapq docs should be more precise about how to access the smallest element type: behavior versions: Python 2.7, Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23549 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23548] TypeError in event loop finalizer, new in Python 3.4.3
Jack O'Connor added the comment: `close()` fixes it; thanks for the workaround! When I throw a print statement inside `remove_signal_handler`, it says that sig is 17 and handler is 0. 17 looks to be SIGCHLD, presumably from the little echo subprocess exiting in this example. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23548 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23548] TypeError in event loop finalizer, new in Python 3.4.3
New submission from Jack O'Connor:
This toy program:
import asyncio
@asyncio.coroutine
def main():
p = yield from asyncio.create_subprocess_shell('echo hi')
yield from p.wait()
asyncio.get_event_loop().run_until_complete(main())
Produces this output on Arch Linux under Python 3.4.3 (but not 3.4.2):
hi

[issue23539] Content-length not set for HTTP methods expecting body when body is None
James Rutherford added the comment: Happy to remove OPTIONS from the list of methods that gets a content-length where body is None, but do we also want to consider behaviour if it's the empty string? My feeling is that '' implies present but empty (so should have a content-length set to zero), whereas None implies missing (so should only have a content-length header set to zero if the method is expecting a body. I've updated the patch with this logic, including ensuring proper explicit test coverage for the cases described. Docs updated too. -- Added file: http://bugs.python.org/file38276/issue23539-py27.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23539 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Or was it written in something else and then ported? Guido, probably. And what other language would you suggest? What other language has comparably extensive multi-platform support? Writing a Python implementation in C instantly makes Python available on all sorts of platforms, with direct access to native libraries on all of them. For example, CPython on Windows can make use of a whole bunch of Microsoft's win32 APIs, via the pywin32 extensions; meanwhile, CPython on Linux can use the inotify functions, again via an extension module (pyinotify or python-inotify). Jython doesn't offer that, as far as I know; or rather, Jython offers access to Java classes rather than to C libraries, and there are a lot more of the latter than the former. Of all the languages that offer convenient access to the same sorts of libraries that C code can (generally, those that compile to machine code and use the same kinds of linker information), which would you suggest as being better than C? C may not be perfect, but it's pretty decent at what it does.

Sometimes they need to be majorly sleep-deprived at half past three in the morning so they're looking at message bodies and skipping the headers that say who actually said stuff... but you'll catch someone.

[issue23552] Have timeit warn about runs that are not independent of each other
New submission from Raymond Hettinger: IPython 3.0 added a useful feature that we ought to consider for inclusion either in timeit.repeat() or in the command-line interface: Using %timeit prints warnings if there is at least a 4x difference in timings between the slowest and fastest runs, since this might meant that the multiple runs are not independent of one another. -- components: Library (Lib) messages: 236908 nosy: rhettinger priority: normal severity: normal status: open title: Have timeit warn about runs that are not independent of each other type: enhancement versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23552 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
