[issue19822] PEP process entrypoint
anatoly techtonik added the comment: The entrypoint here means the point of entry for new Python Enhancement Proposals. Christian, what you propose is a 4th order link for someone who knows what PEPs are, and clones PEP repository to submit own proposal. What I propose it to make PEP repository self-sufficient, so that person who cloned it, can immediately get to work. You can argue that people who don't have time to read on all previous stuff, should not write PEPs, but I'd object that it is good to be inclusive. -- resolution: invalid - status: closed - pending ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19822 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

anatoly techtonik added the comment: The process you are describing is not correct. In particular, the discussion happens before sending in a pull request. Post the link to correct process into README.rst and then this issue can be closed. As for python-dev, I thought it is too obvious and minor issue (still issue) to raise there, so it is just a matter of somebody with knowledge, time and commit privileges to commit the patch. It may worth to raise the question there anyway as I see that communicating usability concerns is a big problem. -- resolution: invalid - status: closed - open ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19822 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19824] string.Template: Add PHP-style variable expansion example
New submission from anatoly techtonik:
http://docs.python.org/2/library/string.html#template-strings
This class could be more useful with the following example:
from string import Template
t = Template('$who likes $what')
who = 'tim'
what = 'kung pao'
t.substitute(locals())
'tim likes kung pao'
This will help PHP folks to transition their .php files.

anatoly techtonik added the comment: The ticket has been closed by two people. Why do you keep re-opening the ticket? Because you're not providing any arguments. If it is not important for you, just ignore. If something is not clear - ask. What you do is just closing the stuff, because you _feel_ that is not an issue. Provide rationale, address my points and then I'll close it myself. The particular stuff that is not clarified: Post the link to correct process into README.rst and then this issue can be closed. The repo readme is not the right place for this. Christian already mentioned the PEPs and anything should go into the dev guide. I want to know why PEPs repository README is not the place to direct users to starting point for submitting enhancement proposals? If you have something to contribute, please open a ticket, add a patch and request review. I am already keep opening it, damn. I want to contribute an improvement for the PEP process and not forget about it.

[issue19824] string.Template: Add PHP-style variable expansion example
anatoly techtonik added the comment: There is nothing to add to the class itself. It is about expanding docs section with helpful examples. `string.Template` is undervalued, because it is hard to see how it can be more useful than standard string formatting functions. But for people coming from PHP world, this can be a good start. The docs just need an entrypoint that shows how to use locally defined variables in template string. PHP does this for strings automatically. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19824 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I really like the brevity, and it is the function that does the magic, so it is fully transparent and you don't need to instantiate string.Template every time. I think its awesome. Do you have some explanations why passing locals() to string.Template is anti-pattern?

[issue19655] Replace the ASDL parser carried with CPython
anatoly techtonik added the comment: +1 for initiative, points that are nice to be addressed are below. 1. Python 3.4 with modern idioms - too Python-specific code raises the barrier. I'd prefer simplicity and portability over modernism. Like how hard is it to port the parser into JS with PythonJS, for example? 2. ASDL specification is mostly offline. One PDF survived, but IR browser and source for did not, which is a pity, because visual tools are one of the most attractive. In any case, it may worth to contact university - they might have backups and resurrect browser in Python (GCI, GSoC). 3. File organization. This is bad: Grammar/Grammar Parser/ Python/ This is good: Core/README.md Core/Grammar Core/Parser/ Core/Processor/ (builds AST) Core/Interpreter/ Core/Tests/ I wonder what is PyPy layout? It may worth to steal it for consistency. 4. Specific problem with ASDL parsing - currently, by ASDL syntax all `expr` are allowed on the left side of assign node. This is not true for real app. It makes sense to clarify in README.md these borders (who checks what) and modify ASDL to reflect the restriction. -- nosy: +techtonik ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19655 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19121] Documentation guidelines enhancements
New submission from anatoly techtonik: I'll raise some points and then suggest how to fix that. issue19060 it appeared that list of functions that subprocess replaces imbues readers with uncertainty, because this list is not complete. Current http://docs.python.org/devguide/documenting.html guide doesn't pay attention that information should be complete and unambiguous. issue19060 is a good example of completeness requirement - user should not be left guessing what other functions can be or can not be replaced by subprocess. Unambiguous means that there should also be answer why they can or can not be replaced. For subprocess this info is partially provided in replacing older functions chapter. There also should not be a place for subjective judgement, fear and desperation. If something can not be done with subprocess, users should not be discouraged (left in fear) to use older functions. If there are valid points where subprocess is not good, they should be described in advanced section. If the description is too long to read, it should be linked. Somebody may raise the point that subprocess docs is not the best place for such list. But between choice to be complete and structured, the former should take precedence. When documentation is complete enough, it's text can be restructured. This further raises a point about structure of docs. Both main docs and guidelines itself. Main docs structure. The more unambiguous, complete and concise documentation is, the better it is for understanding. Currently our docs really miss overviews and summaries. Some may argue that there is no place for that in official docs, especially if such summaries will contain info about history and changes between Python versions. But I'd say that if there is no place, we need to find it for them. Just two examples. MSDN and Python Cookbook both are examples of perfect documentation and these both include overview chapters before function reference. When where is a critical mass of info related to child process execution and management, it is worth to make an overview. Guidelines structure. ToC. Sphinx ToCs are too narrow - they are hard to read. If ToC is present in side panel for navigation, it is not the reason not to include it below the page header for human readers to see the structure of the doc. I find it extremely hard (unnatural) to scan the side panel for the doc structure. This should be split between markup and content guidelines. Right now the structure of docs is: 7. Documenting Python 7.1. Introduction 7.2. Style guide 7.2.1. Use of whitespace 7.2.2. Footnotes 7.2.3. Capitalization 7.2.4. Affirmative Tone 7.2.5. Economy of Expression 7.2.6. Code Examples 7.2.7. Code Equivalents 7.2.8. Audience 7.3. reStructuredText Primer 7.3.1. Paragraphs 7.3.2. Inline markup 7.3.3. Lists and Quotes 7.3.4. Source Code 7.3.5. Hyperlinks 7.3.5.1. External links 7.3.5.2. Internal links 7.3.6. Sections 7.3.7. Explicit Markup 7.3.8. Directives 7.3.9. Footnotes 7.3.10. Comments 7.3.11. Source encoding 7.3.12. Gotchas 7.4. Additional Markup Constructs 7.4.1. Meta-information markup 7.4.2. Module-specific markup 7.4.3. Information units 7.4.4. Showing code examples 7.4.5. Inline markup 7.4.6. Cross-linking markup 7.4.7. Paragraph-level markup 7.4.8. Table-of-contents markup 7.4.9. Index-generating markup 7.4.10. Grammar production displays 7.4.11. Substitutions 7.5. Differences to the LaTeX markup 7.5.1. Inline markup 7.5.2. Information units 7.5.3. Structure 7.6. Building the documentation 7.6.1. Using make 7.6.2. Without make As you may see the 90% of the ToC is markup reference. Some topics like Hyperlinks are oversplit. Making two chapter for just one sentence is an obsession with structure. That's ok for coding, but for readability I would just make it into a list in one chapter, renamed to Linking and merged cross-linking markup section into it. 7.2.3. Capitalization 7.2.4. Affirmative Tone 7.2.5. Economy of Expression 7.2.6. Code Examples As you may see, the Content writing is perfectly mixed with Content formatting into the mix of rules for proper whitespace formatting. This perfectly characterizes us coders, who often mix the concept of good code which is bug-free with concept of good code which is PEP-8 compliant. I mean that it leaves expression that most of the document is about rules, regulations and nitpicking about how you should format the text, not how you should write. Let's make this unambiguous - Content of documentation is essential info that readers need to know. Format of docs is the markup, whitespace, examples, footnotes and other stuff. Content guidelines say that you should insert footnotes, Format guidelines show how to do this. Content guidelines should not distract from the content aspects. So, the Style Guide should be split into Content Writing and Formatting Guidelines [ ]. Or moves into separate file at all. The Content Writing chapter. Should

[issue19124] os.execv executes in background on Windows
New submission from anatoly techtonik:
os.execv() starts process in background on Windows. Because it inherits
stdin/stdout handlers from the process that launched Python interpreter, this
becomes a source of numerous weird bugs, from polluting the stdout stream of
parent to completely blocking its input.
Example session on Windows. Open cmd.exe and run attached testexecvchild.py. It
starts child process with execv(). Child pauses for 2 seconds during which I
type 'echo Hello' and hit Enter.
With Python 3 is pollutes parent output after 3 seconds:
python testexecvchild.py
echo Hello
Hello
Traceback (most recent call last):
File testexecvchild.py, line 7, in module
raw_input('xxx')
NameError: name 'raw_input' is not defined
With Python 2 the stdin of cmd.exe is blocked:
py testexecvchild.py
echo Hello
Hello
xxxecho Hello
Hello
echo Hello
testexecvchild.py
passed
echo Hello
Hello
The same behavior on Linux:
$ python testexecvchild.py
echo Hello
xxx testexecvchild.py
passed

The line os.execv(path, args) is equivalent to os.spawnv(os.P_NOWAIT, path, args) os._exit(0) I don't mind if it runs child process with different pid, but why it runs new process in background.

On Unix control is returned to the shell only once the child process *ends*. That was my conclusion also. Although it might be less memory efficient, you would actually get something closer to Unix behaviour by replacing os.execv(...) with sts = os.spawnv(os.P_WAIT, ...) _exit(sts) or sts = subprocess.call(...) _exit(sts) This is why I said that execv() is useless on Windows and that you should just use subprocess instead. The problem is not in what I should or should not use. The problem that existing scripts that work on Unix and use os.execv() to launch interactive scripts, on Windows behave absolutely weird and unusable behavior.

No one seems to know how to write such a quoting function. Why escape quotes with slash and surrounding in quotes doesn't help? http://msdn.microsoft.com/en-us/library/ms235416(v=vs.90).aspx How does Linux and subprocess on Windows survive then? If I am not mistaken both subprocess and execv on Windows use CreateProcess. Does subprocess fail as well? Does it start child process in foreground or in background? Did you compile examples on http://msdn.microsoft.com/en-us/library/431x4c1w.aspx page with new VC++ to check? I don't possess the VC++ 10, so I can't do this myself. And I believe that compiling with GCC may lead to different results. There is no such thing as a background task in Windows. A process is either attached to a console, or it isn't. When you use execv() to start a process, it inherits the parent's console. All right. Then why does it start to interfere with running cmd.exe (in issue19124)? If it inherits console, it should continue to own it exclusively, and not return it back to parent cmd.exe On Unix try replacing os.execv(...) by os.spawnv(os.P_NOWAIT, ...) os._exit(0) and you will probably get the same behaviour where the shell and the child process both behave as conflicting foreground tasks. Maybe Python code doesn't use _execv() at all on Windows and uses these spawnv's? .. I don't mind if it runs child process with different pid, but why it runs new process in background. Unix version doesn't do this. The point is that the shell waits for its child process to finish by using waitpid() (or something similar) on the child's pid. If the child uses execv() then the child is replaced by a grandchild process with the same pid. From the point of view of the shell, the child and the grandchild are the same process, and waitpid() will not stop until the grandchild terminates. I can not accept your point when you don't know for sure how cmd.exe waits for child process to exit. Are you sure that it doesn't use some blocking CreateProcess call? Are you sure that Python on Windows calls exactly _execv and not some spawn surrogate? This issue should be closed: just use subprocess instead. We need some quorum on this. I'd like to hear two more people that can confirm and agree with your position. I don't want to think that usability of execv() on Windows can not be improved, because people who love Linux doesn't think that this OS deserves some care. I'd like to run Python scripts with the same base behaviour regardless of platform.

There are certainly optimization opportunities, but that never relieves you of making sure you read the whole content that's relevant to you. There is nothing wrong with CSS or mobile design. There is an issue with the placement of this specific piece of information, which comes detached from the place (module description) where it belongs.

[issue19024] Document asterisk (*), splat or star operator
New submission from anatoly techtonik: I'd say this is a critical documentation bug that leads to head bang when you try to figure out what does '*' in code means. This bug is two fold: 1. Define a dedicated place in documentation for '*' operator with examples.

[issue19026] OrderedDict should not accept dict as parameter
New submission from anatoly techtonik:
http://stackoverflow.com/questions/15733558/python-ordereddict-not-keeping-element-order
I wonder why OrderedDict accepts dict as parameter in a first place? OD is used
when order is important and if plain dict is supplied, the order is lost.
d = {3:4, 1:2}
OD(d)
OrderedDict([(1, 2), (3, 4)])
OrderedDict should not accept dict as parameter.

anatoly techtonik added the comment: I don't know if it is bug or feature. There are probably cases when order is not important and OrderedDict is used, but I don't remember any.

[issue19026] OrderedDict should not accept dict as parameter
anatoly techtonik added the comment: On Sun, Sep 15, 2013 at 9:25 PM, Raymond Hettinger rep...@bugs.python.org wrote: In general, it is not possible for a hypothetical StrictOrderedDict to know whether its input was ordered or not. Right. That's why it should not accept input that can only be unordered (including dict and **kwargs) - this is what I mean by strict mode. Remember, Armin's core concept for OrderedDict was to remember the order that keys were added, the order is determined by whoever does the adding. IMHO the statement the order is determined by whoever does the adding is false in 9/10 cases of passed dict. In 9/10 cases whoever supplies dict or **kwargs argument is unaware of what mistake he is making, and how many hour she will spend discovering the issue. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19026 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18535] termios.tcgetattr should return namedtuple
anatoly techtonik added the comment:
Do not hijack the issue - value interpretation is the next step, which better
keep out of scope for this improvement. termios is a C interface, which
documents the meaning of TIOCGWINSZ and has defined names for structure
entries, such as lflag. This issue is to make Python code at least as readable
as C.
C doesn't allow you to revert value meaning from ('\x1b') to text form.

[issue18298] pythonw.exe fails with redirected stderr
anatoly techtonik added the comment: I am not using pythonw.exe, it is the option users prefer to run the program. pythonw.exe is a binary, how do you propose to patch that? Or is it translated to .exe with RPython? Can you be more specific what shell does not work correctly, what exactly does not work correctly, and what is the backward-incompatible behaviour that you want to avoid? pythonw.exe is meant to suppresses the terminal window on startup (console window to be exact), but not to kill vital streams for an application.

[issue706263] print in pythonw raises silent exception when no console available
anatoly techtonik added the comment: This is still an issue for Python 2 users. Most important that pythonw.exe has a magic ability to fail silently leaving users with no means to create valid bug reports (the reason why StackOverflow questions are downvoted and erased). http://bugs.ascend4.org/print_bug_page.php?bug_id=471 stream https://code.google.com/p/spyderlib/issues/detail?id=1260 The argument in msg15198 is somewhat misleading. If pythonw.exe fails because of print statement or because other issue, there is no way to report that. Anyway, this reminds me very much of mod_wsgi, with only problem that Python developers don't receive as much feedback as Graham to make the change: http://blog.dscpl.com.au/2009/04/wsgi-and-printing-to-standard-output.html -- nosy: +techtonik title: print raises exception when no console available - print in pythonw raises silent exception when no console available ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue706263 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
