[issue20341] Argument Clinic: add nullable ints
Larry Hastings added the comment: Yes, that is a different name that seems to mean much the same thing. and which is much more understandable by a Python developer. Thanks for your opinion. Changing error to an char and moving it to the end would save exactly zero bytes, because the compiler *will* align stack variables to 4 byte boundaries. Except if other stack variables happen to be shorter than an int, perhaps. Do we use a lot of those? But regardless, it doesn't cost anything to do so, so why not do it? I thought I just got through explaining how it is slightly slower. There is no benefit in changing them to char, so why do it? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20341 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20359] Having escape sequences (like color codes) in the sys.ps1 messes up readline's input line calculations

[issue20360] inspect.Signature could provide readable expressions for default values for builtins
New submission from Larry Hastings: The signatures for builtins are stored as text and interpreted at runtime on demand. inspect.Signature gets the default value for a parameter as a text string, which it evaluates (by hand, in a highly constrained way) to produce the parameter's value member. Serhiy cleverly suggested that it'd be nice if Signature objects could also make this string available, as it's often more readable than the value. For example, there's a parameter in zlib with the default MAX_DECOMPRESSION - 1; that turns into 7 I think. Which would you prefer? Right now there's no place to store this in the parameter object, so it can't happen for 3.4. But perhaps in 3.5 we could add it, and figure out how to present it to the user. For example __str__ could use it. Thinking a little laterally: we *could* hide it in a *private* member on the Parameter object, then only use it for calculating __str__. That would look so fancy! Should we consider doing that for 3.4? -- messages: 208892 nosy: brett.cannon, larry, ncoghlan, serhiy.storchaka, yselivanov priority: normal severity: normal stage: needs patch status: open title: inspect.Signature could provide readable expressions for default values for builtins type: enhancement versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20360 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue20338] Idle: increase max calltip width
Terry J. Reedy added the comment:
1. For multiple reasons, I want to at least start with only wrapping the
signature string.
I want to keep the code as simple and fast as possible, and not worry much
about rare oddball or PEP8-violating cases. I want to only do what is needed
for the purpose of calltips, which is to remind one of the call sequence.
Adding more detracts from that purpose. Tips are not intended to replace using
the doc or help(f) to learn about f.
As it is, I am not happy about possibly including more than 1 or 2 lines of a
docstring for Python-coded functions. I intend to revisit that when the dust
settles with Clinic and inspect. That fact that another patch *will* be needed,
almost certainly, is another reason to not do too much now.
Wrapping overly long docstrings should not needed. Even if the initial _MAX_COL
slice of the first line of the docstring of a Python-coded function fails to
say enough about the return value, there is help(f) to get full details.
I reread PEP 8 and, contrary to what I (mis) remembered, it says that
docstrings should remain limited to 72 (or 79) chars *even if* a project
increases the limit for *code* lines up to say, 100. The reason for this is
precisely because other software, like help, Idle, and others, read, process,
and display docstrings. If docstrings violate this, I think they should be
changed, and not accomadated (except as suggested below).
So I want to add, before the docstring fetch, only this:
if len(argspec) _MAX_COLS:
argspec = textwrap.wrap(argspec, _MAX_COLS,
subsequent_indent=' ')
dict is definitely an oddball and I do not want to include it in a test at this
time. I do not mind suggesting help(dict), though the current docstring is
incomplete. Here is the real signature and description, which I verified from
the examples below. The multiple example lines should follow a condensed
summary.
def dict([map_or_it,] **kwds)
'''Return new dictionary initialized from pairs of positional-only
map_or_it, if present, and updated with kwds, if present.
start current docstring with specifics
'''
dict({'a':1}, b=2)
{'b': 2, 'a': 1}
dict({'a':1}, a=2)
{'a': 2}
2. For two reasons, I want to increase _MAX_COLS a bit, say to 85.
First, when wrapping a signature, the 'words' after the first few typically
have the form 'name=value'. They will average much longer than the average
English word (4, I think). The average wrapped line length will be _MAX_COLS -
half the average 'word' length. For example (one which should become a test):
for line in textwrap.wrap(str(signature(textwrap.TextWrapper)),
width = 85, subsequent_indent=' '):
print(line)
(width=70, initial_indent='', subsequent_indent='', expand_tabs=True,
replace_whitespace=True, fix_sentence_endings=False, break_long_words=True,
drop_whitespace=True, break_on_hyphens=True, tabsize=8, *, max_lines=None,
placeholder=' [...]')
The lengths, including indents, are 69, 78, 77, and 24, all = 79. Very few
signature lines, wrapped or not, will fall in [80-85].
Second, PEP 8 allows initial summary lines to be 79 chars, as they are not
flowing long blocks of text. (I verified this with Guido.) Some docstrings in
the stdlib 'cheat' a few chars, and 85 will accommodate those without ever
being excessively long.

[issue20364] Rename explain sqlite3.Cursor.execute 'parameters' param
New submission from Terry J. Reedy: execute(sql[, parameters]) Executes an SQL statement. The SQL statement may be parametrized (i. e. placeholders instead of SQL literals). The sqlite3 module supports two kinds of placeholders: question marks (qmark style) and named placeholders (named style). Experimental facts based on experiments with the code example in the doc, using 3.4.b2: 'parameters' is a single subscriptable collection parameter, sequence or dict, that might be called seq_dict. It is positional only, so whatever name is used is a dummy. Only one placeholder style can be used in a given SQL statement string. If question marks are used, seq_dict must be a sequence. If names are used, seq_dict can be either a sequence or dict or subclass thereof. A UserDict is treated as a sequence and raises KeyError(0). Possible text that encompasses the above, replacing the last sentence: A statement may use one of two kinds of placeholders: question marks (qmark style) or named placeholders (named style). For qmark style, seq_dict must be a sequence. For named style, it can be either a sequence or dict instance. Len(seq_dict) must match the number of placeholders. After cleaning up the test file, I will verify on 2.7 and upload. -- assignee: docs@python components: Documentation, Library (Lib) messages: 208908 nosy: docs@python, terry.reedy priority: normal severity: normal stage: patch review status: open title: Rename explain sqlite3.Cursor.execute 'parameters' param type: behavior versions: Python 2.7, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20364 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

The tolerance can be a simple factor, a floating point number = 1.0. For example, replace: 0.09 = t1-t0 = 0.9, t1-t0 with 0.1 - 0.01 * factor = t1-t0 = 0.1 + 0.8 * factor or a new test function: check_timing(t1-t0, 0.1, 0.01, 0.8) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20336 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20297] concurrent.futures.as_completed() installs waiters for already completed Futures
STINNER Victor added the comment: I attached Glenn's function as a patch. Comments on as_completed_proposed.patch: - _create_and_install_waiters() doesn't remove duplicates using set(), so you change the behaving of as_completed(). I don't think that it is correct. as_completed([f, f]) should yield f twice, but I didn't check the current behaviour. Future._waiters is a list and so accept duplicated waiters. - you replaced the _AcquireFutures context manager on all futures with an individual lock. In my opinion, it should be changed in a different patch. I don't know which option is better, but if it is changed, it should be changed in the whole file. @Glenn: You should take a look at the Python Developer's Guide to learn how to write a patch and how to contribute to Python ;-) http://docs.python.org/devguide/ -- keywords: +patch nosy: +haypo Added file: http://bugs.python.org/file33654/as_completed_proposed.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20297 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Larry Hastings added the comment: At last, my refreshed patch. Changes from the previous patch: * Had another mildly bright idea. The name PyTypeObject *cls is a holdover from Python 2.2 days, before the merging of classes and types. Now they're both the same thing and the official name in Python is type. So the self_converter uses the word type. * Added __text_signature__ to PyType_Type. * Removed __text_signature__ from PyMemberDescr_Type, as it's not callable. (What was I thinking!) * Hand-coded signatures for default docstrings for slots. * Hand-coded signature for type and object. (The one for type isn't correct, I know, we'll get there.) * clinic.py now generates self/module/type parameters for most text signatures; these are then stripped off if the function is bound. * Ensured that inspect.signature raises ValueError if it can't generate a signature for a callable object. * Added unit tests. * Suppress the null self parameter for METH_STATIC calls in the impl. * If you have an empty docstring for __new__ or __init__, it suppresses the static variables completely. * Functions with a self converter use the type of self for the parsing function. (Except __new__ and __init__, which must conform to using PyObject *.)

Future._waiters is a list and so accept duplicated waiters.

Also, the behaviour of as_completed([f,f]) and wait([f,f], return_when=ALL_COMPLETED) is currently different. wait will only yield f once. -- Added file: http://bugs.python.org/file33656/test_dupfuture.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20297 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Antoine Pitrou added the comment: Which parts of the API merit discussion? The method names? Whether to include readlines/writelines? The arguments? I think the readlines/writelines methods, as well as the size argument, should be dropped.

[issue20359] Having escape sequences (like color codes) in the sys.ps1 messes up readline's input line calculations
Steve added the comment: Hi Georg, Thanks again for the responses and your help. After a bit of research, I discovered the /reasons/ behind needing the \001 and \002 escapes. Thought I'd log the links here for posterity sake: - To color something in on a color capable terminal console you just need to use the \033[color codem escape sequence. This would be sufficient[1] - However readline messes up the line width calculation because it measures the escape sequences as a characters too. To avoid this you have to wrap the escape sequences within \001 and \002.[2] - On some terminal applications (like the one I am using - terminator[3]), if you add the \001 and \002 escapes to color text which is *not* interpreted by readline, (for instance if you have a single function to color text and you want to use it to color both your sys.ps1 and output text), the \001 and \002 codes will get printed out using a representation (like a unicode 'box'[4]). So, one would have to workaround that in the text coloring function.

[issue20341] Argument Clinic: add nullable ints
Antoine Pitrou added the comment: The only place where nullable appears in the doc tree is... clinic.rst (in reference to places where a C pointer can be NULL, which *is* a reasonable use of the term). There's another problem in the patch: if you define nullable_int_t and nullable_Py_ssize_t in a public header (longobject.h), then you probably need to prefix them with _Py (so: _Py_nullable_int_t and _Py_nullable_ssize_t, for example).

[issue20368] Tkinter: handle the null character
New submission from Serhiy Storchaka: Tcl/Tk uses modified UTF-8 encoding to represent strings as C strings (char*). Because C strings are NUL-terminated, the null character represented as illegal UTF-8 sequence \xc0\x80. Current Tkinter code is not very aware about this. It has special handling the \xc0\x80 string (i.e. encoded single null character) in one place, but doesn't handle encoded null character contained in larger string. As result Tkinter may truncate strings contained the null character, or return wrong result. The proposed patch fixes many issues with the null character (converting from Tcl to Python strings). NUL is still forbidden in string arguments of many methods. Also the patch enhances error handling for variable-related commands. -- components: Extension Modules, Tkinter files: tkinter_null_character.patch keywords: patch messages: 208954 nosy: gpolo, kbk, loewis, roger.serwy, serhiy.storchaka, terry.reedy priority: normal severity: normal stage: patch review status: open title: Tkinter: handle the null character type: behavior versions: Python 2.7, Python 3.3, Python 3.4 Added file: http://bugs.python.org/file33659/tkinter_null_character.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20368 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20367] concurrent.futures.as_completed() fails when given duplicate Futures
Glenn Langford added the comment: There is a subtlety in the as_completed() code which explains a lot - note that finished starts off as a set in the _AcquireFutures block. So if a Future f has already completed, as_completed( [f,f] ) will only yield f once, because f appears once in the finished set. Later on when waiter events are processed, finished turns into a list because of the line: finished = waiter.finished_futures So any duplicates in that list will cause problems in pending.remove(Future). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20367 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20369] concurrent.futures.wait() blocks forever when given duplicate Futures
New submission from Glenn Langford: For a Future f which has already completed, wait( [f,f], return_when=ALL_COMPLETED ) blocks forever. This is because the test in wait(): if len(done) == len(fs) is comparing the length of a set to the length of a list. If f has not completed, wait( [f,f] ) will yield f once. The behaviour should be consistent with as_completed() - see issue #20367. -- files: test_dupfuture_wait.py messages: 208960 nosy: glangford, haypo, mark.dickinson, tim.peters priority: normal severity: normal status: open title: concurrent.futures.wait() blocks forever when given duplicate Futures versions: Python 3.3, Python 3.4 Added file: http://bugs.python.org/file33660/test_dupfuture_wait.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20369 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue20367] concurrent.futures.as_completed() fails when given duplicate Futures
Guido van Rossum added the comment: I think you the caller was wrong to pass in [f, f] in the first place. In asyncio, the argument is converted into a set before using it, but there's still a bug if you pass it a list containing two references to the same coroutine -- it gets wrapped in two separate Futures. I think the better behavior is to convert to a set first and then map coroutines to Futures. So concurrent.futures should also convert to a set first. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20367 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
