[issue24849] Add __len__ to map, everything in itertools
flying sheep added the comment: The *iterable* itself may be reentrant, but the iterator formed from iter(iterable) is not. So by your previous comment, giving the iterator form a length is not appropriate. With the exception of tee, all the functions in itertools return iterators. ah, so your gripe is that the itertools functions return iterators, not (possibly) reentrant objects like range(). and changing that would break backwards compatibility, since the documentation says “iterator”, not “iterable” (i.e. people can expect e.g. next(groupby(...))) to work. that’s probably the end of this :( the only thing i can imagine that adds reentrant properties (and an useful len()) to iterators would be an optional function (maybe __uniter__ :D) that returns an iterable whose __iter__ function creates a restarted iterator copy, or an optional function that directly returns such a copy. probably too much to ask for :/ Since you can't rely on it having a length, you have to program as if it doesn't. So in practice, I believe this will just add complication. I don’t agree here. If something accepts iterables and expects to sometimes be called on iterators and sometimes on sequences/len()gthy objects, it will already try/catch len(iterable) and do something useful if that succeeds. The best we ended-up with has having __length_hint__ to indicate size to list(). Just out of interest, how does my __uniter__ compare? because it changed their boolean value from always-true it does? is it forbidden to define methods so that int(bool(o)) != len(o)? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24849 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24856] Mock.side_effect as iterable or iterator
New submission from Martijn Pieters: The documentation states that `side_effect` can be set to an [iterable](https://docs.python.org/3/glossary.html#term-iterable): If you pass in an iterable, it is used to retrieve an iterator which must yield a value on every call. This value can either be an exception instance to be raised, or a value to be returned from the call to the mock (`DEFAULT` handling is identical to the function case). but the [actual handling of the side effect](https://github.com/testing-cabal/mock/blob/27a20329b25c8de200a8964ed5dd7762322e91f6/mock/mock.py#L1112-L1123) expects it to be an [*iterator*](https://docs.python.org/3/glossary.html#term-iterator): if not _callable(effect): result = next(effect) This excludes using a list or tuple object to produce the side effect sequence. Can the documentation be updated to state an *iterator* is required (so an object that defines __next__ and who's __iter__ method returns self), or can the CallableMixin constructor be updated to call iter() on the side_effect argument if it is not an exception or a callable? You could even re-use the [_MockIter() class](https://hg.python.org/cpython/file/256d2f01e975/Lib/unittest/mock.py#l348) already used for the [NonCallableMock.side_effect property](https://hg.python.org/cpython/file/256d2f01e975/Lib/unittest/mock.py#l509). -- components: Library (Lib) messages: 248501 nosy: mjpieters priority: normal severity: normal status: open title: Mock.side_effect as iterable or iterator versions: Python 3.4, Python 3.5, Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24856 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18383] test_warnings modifies warnings.filters when running with -W default
Alex Shkop added the comment: @rbcollins that is exactly what was trying to say in previous comment. We can make a change to current patch that won't affect behavior. In old API in this sequence of filters last filter was never used: simplefilter(ignore) simplefilter(error, append=True) simplefilter(ignore, append=True) # never used So I suggest that new patch should work like this: simplefilter(error) simplefilter(ignore, append=True) # appends new filter to the end simplefilter(ignore) simplefilter(error, append=True) simplefilter(ignore, append=True) # does nothing since same filter is present. This way filtering will work in the same way it worked before patch and we won't have duplicates.

How about the following. The idlelib package implements the Idle application, which include an interactive shell and editor. The files named idle.* should be used to start Idle. The other files are private implementations and should not be imported by other applications. Their details are subject to change. See PEP 434 for more informaton. 2. Put same in NEWS.txt -- not just a notice that a notice was added to .__init__, but the notice itself. 3. Put a single line at the top of each 'new' file. Perhaps # Private implementation module. API subject to change. 4. 'Old' files, which will go away someday, perhaps as soon as 3.6, are less of a concern to me. If one that has been replaced by a ttk version is imported when use_ttk is true, we can assume that it is being imported by an extension and issue a DeprecationWarning. 5. PyShell is a special case since from idlelib.PyShell import main; main() (essentially the content of idlelib.__main__) was once advertised as the way to start Idle. PyShell is also a special case because it includes startup code, shell code, and editor debug code, making it a prime target for refactoring. If main() were moved elsewhere and __main__.py and idle.* files modified to point to the new location, we could raise a DeprecationWarning in PyShell.main before calling the new main. -- assignee: - terry.reedy priority: normal - high versions: +Python 2.7, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24861 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24860] handling of IDLE 'open module' errors
Terry J. Reedy added the comment: I see this as two related changes: a) Leave the module name query box open when there is a error, so the user can either correct a mistake (or hit Cancel) without reopening the box and re-entering the module name. Good idea. b) Put the error message in the box itself, perhaps with a beep. I presume there would be no [OK] button, but rather the cursor would remain in the entry box. Nice simplification. I believe 'not a source-based module' means 'not a python-coded module', which seems a little clearer.

How to model government organization hierarchies so that the list can expand and compress
It's like the desktop folder/directory model where you can create unlimited folders and put folders within other folders. Instead of folders, I want to use government organizations. Example: Let user create agency names: Air Force, Marines, Navy, Army. Then let them create an umbrella collection called Pentagon, and let users drag Air Force, Marines, Navy, etc. into the umbrella collection. User may wish to add smaller sub-sets of Army, such as Army Jeep Repair Services User may also want to add a new collection Office of the President and put OMB and Pentagon under that as equals. What would the data model look like for this? If I have a field: next_higher_level_parent that lets children records keep track of parent record, it's hard for me to imagine anything but an inefficient bubble sort to produce a hierarchical organizational list. Am using Postgres, not graph database. I'm hoping someone else has worked on this problem, probably not with government agency names, but perhaps the same principle with other objects. Thanks!

Re: Module load times
Hi Stefan, How is the DLL binding implemented? Using ctypes? Or something else? It is through ctypes. Obviously, instantiating a large ctypes wrapper will take some time. A binary module would certainly be quicker here, both in terms of import time and execution time. Since you're generating the code anyway, generating Cython code instead shouldn't be difficult but would certainly yield faster code. True, I was using XSLT to auto generate the module. I will however explore this. What makes you think the import might be a problem? That's a one-time thing. Or is your application a command-line tool or so that needs to start and terminate quickly? The code is used within plugin points and soon to be asynchronous code (once the original broken implementation is fixed) where in some cases it will be instantiated 100's of 1000's of times etc...

[issue24861] deprecate importing components of IDLE
New submission from Mark Roseman: One of the concerns with making significant structural changes to the IDLE codebase is breakage of external that might import a piece of idlelib (so not just 'import idlelib' but a particular submodule). PEP 434 already makes the case that this behaviour is unsupported (the modules are undocumented and effectively private implementations). In the interests of not digging this particular hole any further, I'm suggesting we make this official. I don't know what the appropriate mechanism would be (e.g. something in IDLE's README.txt file, something at the top of each IDLE module, etc.). Based on some suggestions on idle-dev, I did some searching to find out what impact this might have. As expected, most uses import the whole thing, either documenting how to run IDLE, or launching it as an external editor. This is done as both import idlelib but also as import idlelib.idle Turtledemo appears to be the only thing in stdlib that imports a piece of idlelib. From nullege.com, one reference to a now-defunct wiki/collaboration tool called Springnote. From programcreek.com, nothing significant. Multiple applications do import PyShell as a way of starting a Python shell in their application. Usually they do just call PyShell.main(). Sometimes though they do reach inside in fairly significant ways that might break if the code were substantially changed. For example, search for PyShell in http://igraph.org/python/doc/igraph.app.shell-pysrc.html I could locate no other significant uses based on Google search, etc. The one exception I would therefore suggest to the no importing submodules would be importing PyShell to open up a Python shell window. I'd go further to suggest that the existing PyShell be called something else, and a new PyShell wrapper be created which documents an official API (with therefore very limited mucking inside), and then delegates to an actual implementation. -- components: IDLE messages: 248540 nosy: Al.Sweigart, kbk, markroseman, roger.serwy, terry.reedy priority: normal severity: normal status: open title: deprecate importing components of IDLE type: enhancement versions: Python 3.5, Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24861 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

It is okay to use assertions this way for quick and dirty ad hoc testing, say at the command line, but IMO totally inappropriate for anything more formal, like unit testing. If for no other reason than the use of `assert` for testing makes it impossible to test your code when running with the Python -O (optimize) switch.

My view, for what it's worth: Django is a library, but it's also a framework. The difference isn't really that great, and most frameworks are implemented using libraries. The library vs framework distinction, from an application's standpoint, broadly one of how you structure your code - do you write a bunch of top-level code that calls on library functions, or do you write a bunch of functions that the framework calls on? The distinction can blur some, too. And as Michael says, the slight simplification isn't causing problems, so it's really only a technical correctness issue.

RE: Module load times
Importing is not the same as instantiation. When you import a module, the code is only read from disk and instantiated the first time. Then it is cached. Subsequent imports in the same Python session use the cached version. I do mean imported, in the original design there were many ctype function prototypes, the c developer had ran some tests and showed quite a bit of time taken up just the import over 100 clean imports. I don't have his test harness and hence why I am trying to validate the results. So the answer will depend on your application. If your application runs for a long time (relatively speaking), and imports the plugins 100s or 1000s of times, it should not matter. Only the first import is likely to be slow. But if the application starts up, imports the plugin, then shuts down, then repeats 100s or 1000s of times, that may be slow. Or if it launches separate processes, each of which imports the plugin. Yeah that wasn't clear. The plugins are invoked in fresh interpreter processes and hence modules with import side effects or simply large modules can manifest over time.

[issue24862] subprocess.Popen behaves incorrect when moved in process tree
New submission from Andre Merzky:
- create a class which is a subclass of multiprocessing.Process ('A')
- in its __init__ create new thread ('B') and share a queue with it
- in A's run() method, run 'C=subprocess.Popen(args=/bin/false)'
- push 'C' though the queue to 'B'
- call 'C.pull()' -- returns 0
Apart from returning 0, the pull will also return immediately, even if the task
is long running. The task does not die -- 'ps' shows it is well alive.
I assume that the underlying reason is that 'C' is moved sideways in the
process tree, and the wait is happening in a thread which is not the parent of
C. I assume (or rather guess, really) that the system level waitpid call
raises a 'ECHILD' (see wait(2)), but maybe that is misinterpreted as 'process
gone'?
I append a test script which shows different combinations of process spawner
and watcher classes. All of them should report an exit code of '1' (as all run
/bin/false), or should raise an error. None should report an exit code of 0 --
but some do.
PS.: I implore you not to argue if the above setup makes sense -- it probably
does not. However, it took significant work to condense a real problem into
that small excerpt, and it is not a full representation of our application
stack. I am not interested in discussing alternative approaches: we have
those, and I can live with the error not being fixed.

Re: Module load times
On Fri, 14 Aug 2015 07:12 am, Joseph L. Casale wrote: What makes you think the import might be a problem? That's a one-time thing. Or is your application a command-line tool or so that needs to start and terminate quickly? The code is used within plugin points and soon to be asynchronous code (once the original broken implementation is fixed) where in some cases it will be instantiated 100's of 1000's of times etc... Importing is not the same as instantiation. When you import a module, the code is only read from disk and instantiated the first time. Then it is cached. Subsequent imports in the same Python session use the cached version. So the answer will depend on your application. If your application runs for a long time (relatively speaking), and imports the plugins 100s or 1000s of times, it should not matter. Only the first import is likely to be slow. But if the application starts up, imports the plugin, then shuts down, then repeats 100s or 1000s of times, that may be slow. Or if it launches separate processes, each of which imports the plugin. Without understanding your application, and the plugin model, it is difficult to predict the impact of importing. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

The plugins are invoked in fresh interpreter processes and hence modules with import side effects or simply large modules can manifest over time. If they're invoked in fresh processes, then you're looking at process startup time, and I would recommend using OS-level tools to play around with that. Unix-like systems will usually have a 'time' command which will tell you exactly how much wall and CPU time a process took needed; just create a system that starts up and promptly shuts down, and then you can test iterations that way. Of course, there are a million and one variables (disk caches, other activity on the system, etc), but it's better than nothing. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
[issue24859] ctypes.Structure bit order is reversed - counts from right
Martin Panter added the comment: It would be helpful if you could trim down your example code a bit. Without studying the whole file, it is hard to see exactly what order you are seeing and what order you expect, since there are two versions with different orders in the code. My understanding of the “ctypes” module is that it is for interacting with the local OS, ABI, compiler, etc, which could use various layouts depending on the platform. According to the Linux x86-64 ABI http:/www.x86-64.org/documentation/abi.pdf, page 14, “bit-fields are allocated from right to left”, which I interpret to mean from least-significant to most-significant bit. Not so sure about Windows, but https://msdn.microsoft.com/en-us/library/yszfawxh.aspx suggests a similar story (LSB first). This behaviour agrees with my experiments on Linux and Wine: class Bitfield(Structure): ... _fields_ = ((a, c_uint8, 4), (b, c_uint8, 4)) ... bytes(Bitfield(0xA, 0xB)) b'\xba' Does this agree with what you expect? Otherwise, what leads you to expect something different? Also: * bytes(saej1939_message_id) should copy the bytes directly; no need for a union. * struct.unpack() should also accept a “ctypes” object directly; no need for the copy. -- nosy: +martin.panter ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24859 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Mock object but also assert method calls?
Hi,
How about asserting that test2 of class Bar is called?
Of course I can do a patch for a concrete method but
I was looking for something like:
mocked_object.assert_method_called_with(name=test2, hello)
If find following totally different to the normal API which
is provided by the mock library:
assert call().test2(hello) in mocked_objects.mock_calls
Is there a better way?
APPENDIX:
Foo delegates calls to Bar.
[code]
from mock import patch
with patch(__main__.Bar) as mocked_object:
foo = Foo()
foo.test1()
foo.test2(hello)
print(mocked_object.mock_calls)
# print all calls (c'tor as well as normal methods)
for name, args, kwargs in mocked_object.mock_calls:
print(name, args, kwargs)
[/code]
Generates:
class '__main__.Bar'
test1: Foo has been called
test2: Foo has been called with value hello
[call(), call().test1(), call().test2('hello')]
('', (), {})
('().test1', (), {})
('().test2', ('hello',), {})

[issue24851] infinite loop in faulthandler._stack_overflow
Paul Murphy added the comment: Somehow, you need to preserve access to the stack memory. The generated code is still growing the stack, it just fails to touch any of it. I'm guessing a volatile access would just add an extra non-stack access to the infinite loop. Initially, I had tried creating a non-inlined function to touch the stack memory. It worked in this case, but still required some undesirable compiler specific assistance. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24851 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
