[issue15476] Add code object to glossary
Chris Jerdonek added the comment: That's fine by me. I guess what's more important to me is that code object have a central, linkable definition *somewhere* (and not necessarily that this somewhere be a glossary entry). That way references to code object in the docs can link to a definition in the same way that we link to definitions of other words, functions, etc. I was also planning on indexing the word more properly. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15476 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15853] IDLE crashes selecting Preferences menu with OS X ActiveState Tcl/Tk 8.5.12.1
Ned Deily added the comment: The problem is a regression in the latest version of ActiveTcl 8.5 for OS X, specifically 8.5.12.1 (and I believe the previous version 8.5.12.0). It has nothing directly to do with Python or how you might build Python other than whether _tkinter.so dynamically links with /Library/Frameworks/Tcl.framework/Verisons/8.5 and /Library/Framework/Tk.framework/Verisons/8.5 (the locations where ActiveTcl install) as opposed to /System/Library/Frameworks/Tcl.framework/... and /System/Library/Frameworks/Tk.framework/..., the Apple-supplied versions. And, if so, which version of ActiveTcl you have installed. The python.org 64-bit Pythons are vulnerable, the 32-bit-obly ones are not because they link with Tcl/Tk 8.4. Unfortunately, ActiveState only makes available the most recent version of ActiveTcl on its Community Edition pages, so, unless you have access to a copy of an older version of ActiveTcl (like 8.5.11.1, the previous version), you're kind of stuck with the behavior, unless you remove ActiveTcl 8.5 and revert to Apple's Tk which is vulnerable to other crashes that have been fixed in ActiveState's (and is totally broken in OS X 10.6). Or you use the 32-bit installer and Tcl/Tk 8.4. Or you build your own version of Tcl/Tk 8.5 (I've stared looking at that). By the way, ActiveState's own ActivePython 2.7 also crashes the same way when using 8.5.12.x. I've pinged the Tcl Mac mailing list. Unless there's an immediate fix, I'll see what I can find in Tk. http://permalink.gmane.org/gmane.comp.lang.tcl.mac/7080 -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15853 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15298] _sysconfigdata is generated in srcdir, not builddir
Richard Oudkerk added the comment: If sysconfig._generate_posix_vars() creates the build directory and pybuilddir.txt (instead of setup.py) then it could write _sysconfigdata.py in the correct place. Then setup.py would not have to mess with its own sys.path. One issue with having _sysconfigdata.py in the build dir is that distutils copies it (along with everything else in the build dir) to .../lib/python3.x/lib-dynload. So I think Matthias' patch results in two copies of _sysconfigdata.py being installed (plus __pycache__/_sysconfigdata.pyc). -- nosy: +sbt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15298 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15861] ttk.Treeview unmatched open brace in list
Bryan Oakley added the comment:
What behavior do I expect? I expect it to not throw an error. I expect whatever
string I give to be inserted into the widget unadulterated (ie: if I give the
string foo { I expect to see foo { in the widget).
Tkinter is effectively telling me you have a Tcl syntax error. Since I'm
programming in python I should be insulated from that, particularly since the
error comes internally after Tkinter transforms my data.
How Tkinter does it under the hood, I don't care. Tkinter should make sure that
the data it passes to the Tcl interpreter is well-formed.

[issue14847] AttributeError: NoneType has no attribute 'utf_8_decode'
Jason R. Coombs added the comment: I've removed the invocation of the wrapper code in our project, but the issue has not exhibited itself. This leads me to suspect a few possibilities of things that have changed since we had the issue in June: 1) Distribute was updated with its fix for this issue. I don't expect that code was being called in our application, but I didn't strictly rule it out. 2) The application launcher was changed. The old system was fork-based and used pkg_resources and multi-installed packages. The modern deployment is a simple, pip-installed process. 3) The code underwent other unrelated but substantial changes. So although I thought I was on to something when I added the wrapper, suppressing the error, I was never able to detect it, and it seems to have gone away now. I was hoping this would shed more light on the problem and describe another use case, but at this point, that may not happen. Unless the problem recurs in our application, or we have another application where the problem arises, I'll focus on the Python side as suggested by Amaury. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14847 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15866] encode(..., 'xmlcharrefreplace') produces entities for surrogate pairs
New submission from Wim:
Encoding a (well-formed) Unicode string containing a non-BMP character, using
the xmlcharrefreplace error handler, will produce two XML entities for
surrogate codepoints instead of one entity for the actual character.
Here's a transcript (Python 2.7.3, x86_64):
b = '\xf0\x9f\x92\x9d'
u = b.decode('utf8')
u
u'\U0001f49d'
u.encode('ascii', errors='xmlcharrefreplace')
'#55357;#56477;'
( u'\U0001f49d' ).encode('ascii', errors='xmlcharrefreplace')
'#55357;#56477;'
list(u)
[u'\ud83d', u'\udc9d']
u.encode('utf8', errors='xmlcharrefreplace')
'\xf0\x9f\x92\x9d'
The utf8 bytestring is correctly decoded, and the print representation shows
one single Unicode character. Encoding using xmlcharrefreplace produces two XML
entities, which is wrong[1]: a single non-BMP character should be represented
in XML as a single entity reference, in this case presumably '#128157;'.
As the last two lines show, I'm using a narrow build (so the unicode strings
are represented internally in UTF-16, I guess). Converting the string back to
utf8 does the right thing, and emits a single UTF8 sequence representing the
supplementary-plane codepoint.
(FWIW, the backslashreplace error handler also emits a surrogate pair, but I
don't know if there is a complete specification for what that handler does, so
it's possible that it's not wrong.)

[issue11549] Build-out an AST optimizer, moving some functionality out of the peephole optimizer
STINNER Victor added the comment: I'm working on a AST optimizer for Python 2.6-3.3: https://bitbucket.org/haypo/astoptimizer It is implemented in Python and is able to optimize much more cases than the current bytecode peepholer. -- nosy: +haypo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11549] Build-out an AST optimizer, moving some functionality out of the peephole optimizer
Nick Coghlan added the comment: All of the optimisations that assume globals haven't been shadowed or rebound are invalid in the general case. E.g. print(1.5) and print(1.5) are valid for *our* print function, but we technically have no idea if they're equivalent in user code. In short, if it involves a name lookup and that name isn't reserved to the compiler (e.g. __debug__) then no, you're not allowed to optimise it at compile time if you wish to remain compliant with the language spec. Method calls on literals are always fair game, though (e.g. you could optimise a b c.split()) Any stdlib AST optimiser would need to be substantially more conservative by default. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11549] Build-out an AST optimizer, moving some functionality out of the peephole optimizer
STINNER Victor added the comment: All of the optimisations that assume globals haven't been shadowed or rebound are invalid in the general case. My main idea is that the developer of the application should be able to annotate functions and constants to declare them as optimizable (constant). I chose to expect builtins as not being overrided, but if it breaks applications, it can be converted to an option disabled by default. There is a known issue: test_math fails because pow() is an alias to matH.pow() in doctests. The problem is that from math import * is called and the result is stored in a namespace, and then pow(2,4) is called in the namespace. astoptimizer doesn't detect that pow=math.pow because locals are only set when the code is executed (and not at compilation) with something like: exec(code, namespace). It is a limitation of the optimizer. A workaround is to disable optimizations when running tests. It is possible to detect that builtins are shadowed (ex: print=myprint). astoptimizer has an experimental support of assignments, but it only works on trivial examples yet (like x=1; print(x)) and is disabled by default (because it is buggy). I also plan to disable some optimizations if globals(), vars() or dir() is called. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11549] Build-out an AST optimizer, moving some functionality out of the peephole optimizer
STINNER Victor added the comment: Any stdlib AST optimiser would need to be substantially more conservative by default. FYI The test suite of Python 2.7 and 3.3 pass with astoptimizer... except some minor (?) failures: * test_math fails for the reason explained above * test_pdb: it looks to be an issue with line number (debuggers don't like optimizers :-)) * test_xml_etree and test_xml_etree_c: reference count of the None singleton The test suite helped me to find bugs in my optimizer :-) I also had to add some hacks (hasattr) for test_ast (test_ast generates invalid AST trees). The configuration should also be adapted for test_peepholer, because CPython peepholer uses a limit of 20 items, whereas astoptimizer uses a limit of 4096 bytes/characters for string by default. All these minor nits are now handled in a specific cpython_tests config. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Nick Coghlan added the comment: No, you're assuming global program analysis and *that is not a valid assumption*. One of the key features of Python is that *monkeypatching works*. It's not encouraged, but it works. You simply cannot play games with name lookups like this without creating something that is no longer Python. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Eugene Toder added the comment: Method calls on literals are always fair game, though (e.g. you could optimise a b c.split()) What about optimizations that do not change behavior, except for different error messages? E.g. we can change y = [1,2][x] to y = (1,2)[x] where the tuple is constant and is stored in co_consts. This will, however, produce a different text in the exception when x is not 0 or 1. The type of exception is going to be the same. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15867] It's hard to decypher how to build off of the provided objects from the importlib docs
New submission from Julian Berman: I find that the importlib documentation is a bit too low level. Import hooks are not that common, so requiring a bit of reading is OK with me, but I somewhat *understand* PEP 302, so I have a general idea of *what* I want to do and what kind of objects can accomplish that, and still find it hard to figure out how to take the pieces provided by importlib and use them to do what I want. If I provide a specific example, I want to create a path hook that just does the usual import behavior, but before executing the module, does some transformation on the source code, say. In trying to figure out the best way to do that I had a hard time using the docs to figure out which pieces I should assemble to do that. I'm going to just describe the rough series of steps I went through, and hopefully that will help give a picture of where in the docs I had trouble. `importlib.abc` has a few things that would appear to help. None of the things seem like an exact match, so immediately I'm confused -- after reading PEP 302 I'd have expected to need to find an object to implement one or both of `get_code` or `get_source` on, or one that has that implemented that I can subclass and extend. The closest thing there that I find is PyPycLoader, which seems to be saying it implements the standard import behavior, but the docs say its deprecated and to use SourceLoader. At this point, after checking out `SourceLoader` and seeing that it has me implementing two methods whose purpose I don't quite understand, even after reading the short descriptions of them, at least not in the context of what I want to do, I begin to suspect that what I really want is to combine SourceLoader with some things from the `imp` module, or maybe `importlib.__import__`, but am left wondering again how much I need to implement before I just can use that. I then notice `importlib. util.module_for_loader`, and add that to the simple loader I've written which I'm still waiting to plug `imp` into, before realizing that that decorator eats the `fullname` attribute and *only* passes along the module, which confuses me, since now I don't know how to retrieve the source for the module object that I'm being passed -- so I save the path name in `__init__` for the class, and assume that's what I should be doing, despite not seeing an example doing that. Assuming that's even correct as-is, it took me quite a bit to put those pieces together. So I apologize for rambling -- I think essentially what'd improve things is providing more examples, or perhaps a HOWTO entry, that targeted assembling the pieces provided in the module into a few clear, complete examples of finders, loaders and importers. -- assignee: docs@python components: Documentation messages: 169901 nosy: Julian, docs@python priority: normal severity: normal status: open title: It's hard to decypher how to build off of the provided objects from the importlib docs versions: Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15867 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11549] Build-out an AST optimizer, moving some functionality out of the peephole optimizer
Nick Coghlan added the comment:
The peephole optimiser already makes optimisations like that in a couple of
places (e.g. set - frozenset):
def f(x):
...if x in {1, 2}: pass
...
f.__code__.co_consts
(None, 1, 2, frozenset({1, 2}))
It's name lookup semantics that are the real minefield. It's one of the reasons
PyPy's JIT can be so much more effective than a static optimiser - because it's
monitoring real execution and inserting the appropriate guards it's not relying
on invalid assumptions about name bindings.

Eugene Toder added the comment:
If I'm not missing something, changing
x in [1,2]
to
x in (1,2)
and
x in {1,2}
to
x in frozenset([1,2])
does not change any error messages.
Agreed that without dynamic compilation we can pretty much only track literals
(including functions and lambdas) assigned to local variables.
