[issue24449] Please add async write method to asyncio.StreamWriter
Paul Sokolovsky added the comment: Thanks for the response. and an API with more choices is not necessarily better. I certainly agree, and that's why I try to implement MicroPython's uasyncio solely in terms of coroutines, without Futures and Transports. But I of course can't argue for dropping Transports in asyncio, so the only argument I'm left with is consistency of API (letting use coroutines everywhere). I'm sure this has come up before, I could've sworn it was you, sorry if it wasn't. No, I brought issue of Futures dependency (yes, that was wide and long discussion), then about yielding a coroutine instance as a way to schedule it. But during the time I'm on python-tulip, I didn't remember someone bringing up issue of asymmetry between read write, but I would imagine someone would have done that before me. (Which might hint that the issue exists ;-) ). the common mistake (amongst beginners) of forgetting the yield from or 'async' would be much harder to debug So, this is not first time you provide this argument for different cases, one would think that this pin-points pretty serious flaw in the language and it's priority to find a solution for it, and yet PEP3152 which does exactly that was rejected, so maybe it's not that *serious*. Indeed, it's common sense that it's possible to make a hard to debug mistake in any program, and in any concurrent program (doesn't matter of which paradigm) it's order of magnitude easier to do one and harder to debug respectively. But asyncio does have tools to debug such issue. And one would think that easiest way to preclude mistake is to avoid inconsistencies in the API. I know there's a very find balance between all the arguments, and only you can know where it lies, but kindly accept external feedback that the above explanation (syntax is more prone to mistakes) looks like universal objectivized rejection in rather subjective cases. What saddens me here is that this decision puts pretty high lower bound for asyncio memory usage (and I tried hard to prove that asyncio is suitable paradigm even for smaller, IoT-class devices). It's also hard to argue that Python isn't worse than Go, Rust and other new kids on the block - because indeed, how one can argue that, if even the language author uses argument language syntax, while exists, isn't good enough to do the obvious things. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24449 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24454] Improve the usability of the match object named group API
Matthew Barnett added the comment:
I agree that it would be nice if len(mo) == len(mo.groups()), but Serhiy has
explained why that's not the case in the regex module.
The regex module does support mo[name], so:
print('Located coordinate at (%(row)s, %(col)s)' % mo)
print('Located coordinate at ({row}, {col})'.format_map(mo))
already work.

[issue24454] Improve the usability of the match object named group API
Eric V. Smith added the comment:
I'd definitely be for mo['col']. I can't say I've ever used len(mo.groups()).
I do have lots of code like:
return mo.group('col'), mo.group('row'), mo.group('foo')
Using groupdict there is doable but not great. But:
return mo['col'], mo['row'], mo['foo']
would be a definite improvement.

[issue24455] IDLE debugger causes crash if not quitted properly before next run
New submission from irdb: # Open a module using IDLE # Run the module (Press F5) # Activate the debugger ([DEBUG ON]) # Set a breakpoint in the module # Run the module again # Run the module for the third time # Hit the Quit button in Debug Control window (twice, as the first click appears to do nothing) Congratulations!

[issue24454] Improve the usability of the match object named group API
Raymond Hettinger added the comment: but may be implementing access via attributes would be even better? mo.groupnamespace().col or mo.ns.col? The whole point is to eliminate the unnecessary extra level. Contrast using DOM with using ElementTree. The difference in usability and readability is huge. If you do much in the way of regex work, this will be a win: mo['name'], mo['rank'], mo['serialnumber'] There are several problems with trying to turn this into attribute access. One of the usual ones are the conflict between the user fieldnames and the actual methods and attributes of the objects (that is why named tuples have the irritating leading underscore for its own attributes and methods). The other problem is that it interferes with usability when the fieldname is stored in a variable. Contrast, fieldname='rank'; print(mo[fieldname]) with fieldname='rank'; print(getattr(mo, fieldname)). I'm happy to abandon the len(mo) suggestion, but mo[groupname] would be really nice. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24454 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24454] Improve the usability of the match object named group API
Serhiy Storchaka added the comment: The disadvantage of supporting len() is its ambiguousness. Supporting indexing with group name also has disadvantages (benefits already was mentioned above). 1. Indexing with string keys is a part of mapping protocol, and it would be expected that other parts of the protocol if not all are supported (at least len() and iteration), but they are not. 2. If indexing with group names would be supported, it would be expected the support of integer indexes. But this is ambiguous too. This feature would improve the access to named groups (6 characters less to type for every case and better readability), but may be implementing access via attributes would be even better? mo.groupnamespace().col or mo.ns.col? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24454 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24087] Documentation doesn't explain the term coroutine (PEP 342)
Paul Moore added the comment: Personally, I'm OK with the wording in the 3.5.0b2 docs, as far as basic terminology and glossary-style information goes. I think coroutines, async, and event loops are badly under-documented in the broader context, though - there is very little in the docs explaining the concepts and constraints[1] of Python's async features. Unfortunately, the people with the knowledge of the subject are likely to be too close to the details to be able to write beginner-level documentation, and beginners don't know enough (by definition) to do so. I'm trying to do some playing round with creating my own async framework to get a better understanding of how things should work, but it's slow going and honestly I don't feel I've got anything much I could write up at this point. [1] For example, how Python's implementation differs from other languages or theoretical discussions of coroutines in the literature. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24087 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24429] msvcrt error when embedded
Carl Kleffner added the comment: Windows itself is the primary user of msvcrt.dll. A Windows 7 installation has over 1500 DLLs and over 350 executables in System32 that depend on msvcrt.dll. Windows developers such as Raymond Chen get a bit annoyed when projects link directly with msvcrt.dll. In case of mingw32 or mingw-w64 msvcrt linkage is the usual standard due to licensing reasons. The CRT has to be stated as a 'System' library, see http://www.gnu.org/licenses/gpl-faq.html#WindowsRuntimeAndGPL. This is case for msvcrt.dll only. VC runtimes can be linked as well, but this runtime DLLs should'nt deployed alongsinde with the application in this case. As described above python binary extensions has to be linked against the very same VC runtime that is used for Python itself to avoid mixing runtimes in one application. Mixing is considered as evil, see http://siomsystems.com/mixing-visual-studio-versions An important question for Steve concerning python-3.5: python-3.5b2 is linked against the newly introduced 'universal CRT', that is without any doubt a SYSTEM LIBRARY. However, heap memory managment functions and other functions are linked against VCRUNTIME140.dll instead of the ucrtbase.dll. Is this the intended behavior? The symbol memset: this symbol is exposed from ucrtbase.dll as well as vcruntime140.dll.

Martin Panter added the comment: It seems that Issue 24400 may implement __await__() for native coroutine instances, making points 1, 2 and 4 mainly redundant. This would also bypass a fifth problem: the need for the mandatory yet largely useless send(None) argument.

Currently it seems you have to call coro.send(None), but if the current patch for Issue 24400 were applied, I think it would become next(coro), so I will leave this for later. -- dependencies: +Awaitable ABC incompatible with functools.singledispatch keywords: +patch stage: - patch review Added file: http://bugs.python.org/file39714/async-doc.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24439 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Steve Dower added the comment: python-3.5b2 is linked against the newly introduced 'universal CRT', that is without any doubt a SYSTEM LIBRARY. However, heap memory managment functions and other functions are linked against VCRUNTIME140.dll instead of the ucrtbase.dll. Is this the intended behavior? AFAICT, all of the public functions exported from vcruntime140.dll are also exported from api-ms-win-crt-string-l1-1-0.dll (which forwards to ucrtbase.dll), which would make them available as part of the stable ABI. I'm not sure why vcruntime140.dll has its own versions or why they are used in preference, but it may be to do with inlining or intrinsics. vcruntime140.dll exists and is not guaranteed stable because it provides functionality that needs intimate knowledge of the compiler (stack unwinding, etc.). Those string APIs don't make much sense here, so I'd guess they're dependencies that had to be pulled in, and the linker may just be prioritizing those ones by accident. I would not be at all surprised if MinGW had to replace vcruntime140.dll entirely. Nothing from ucrtbase.dll can depend on it, so replacing it is probably for the best. Then just link against either the ucrtbase.dll or the api-ms-win-crt-*.dll libraries. -- ___ 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

[issue24087] Documentation doesn't explain the term coroutine (PEP 342)
Martin Panter added the comment: Okay. The biggest thing that concerns me at the moment to do with the term is that there are too many related but different, specific meanings, that I suspect could be confusing, including: 1. Generators (and presumably also the new “async” native coroutines), compatible with “asyncio”: https://docs.python.org/3.5/library/asyncio-task.html#coroutines 2. PEP 492 “native” coroutines: https://docs.python.org/3.5/glossary.html#term-coroutine-function Okay maybe some of the new wording is not needed any more. I plan to try documenting some basic stuff about the new PEP 492 coroutines in Issue 24439. Maybe I will incorporate the “native coroutine” clarifications from my patch here at the same time. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24087 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
