[issue22458] Add fractions benchmark
New submission from Stefan Behnel: Fractions are great for all sorts of exact computations (including money/currency calculations), but are quite slow due to the need for normalisation at instantiation time. I adapted the existing telco benchmark to use Fraction instead of Decimal to make this problem more visible. One change I made was to take the data reading out of the measured loop. I/O is not part of what the benchmark should measure. Please consider adding it to the benchmark suite. -- components: Benchmarks files: telco_fractions.py messages: 227252 nosy: scoder priority: normal severity: normal status: open title: Add fractions benchmark type: enhancement Added file: http://bugs.python.org/file36684/telco_fractions.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22458 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22433] Argparse considers unknown optional arguments with spaces as a known positional argument
Денис Кореневский added the comment: There is an standard way to solve this ambiguity. There is a special marker '--' used to force argument parsing function treat all arguments given in command after this marker as positional arguments. It was invented specially for tasks where you need to force argument parsing engine ignore option indicator and treat argument as positional. I know this argument as standard 'de facto', but can't find any documents about '--' interpretation. But you can see, that Linux 'libc' standard C library function getopt() knows about this flag: http://linux.die.net/man/3/getopt So, any utility using this function knows about '--'. For example: grep, tee, cat, tail, head, vim, less, rm, rmdir, common shells (sh, bash, csh, dash, ...) and so on. The list is large. Almost any utility except special ones like 'echo' which main function is to print any argument given to utility. So, I think, that the true way here is to parse all arguments staring with '-'/'--' and listed before special '--' marker as optional, and treat all of arguments listed after '--' as positional ones and do not try to use any secondary indicators to make a decision: 'optional' or not. For example: any parameter before '--' special marker starting with '--' is treated as optional # python3 example.py --bar=one two xxx (Namespace(pos='xxx'), ['--bar=one two']) all parameters after '--' special marker are treated as positional # python3 example.py -- --bar=one two xxx (Namespace(pos='--bar=one two'), ['xxx']) Yes, my patch does not the solution and argparse should be patched another way. Where and how can I get unittests for argparse module to check my code modifications before posting them here? I want to try to modify argparse and produce the patch changing argparse behaviour as described above.

[issue22445] Memoryviews require more strict contiguous checks then necessary
Stefan Krah added the comment:
Since the functions in abstract.c have been committed by Travis Oliphant:
Could there have been a reason why the {shape=[1], strides=[-5]}
case was considered but the general case was not?
Or is it generally accepted among the numpy devs that not considering
the general case was just an oversight?

Sebastian Berg added the comment: Yeah, the code does much the same as the old numpy code (at least most of the same funny little things, though I seem to remember the old numpy code had something yet a bit weirder, would have to check). To be honest, I do not know. It isn't implausible that the original numpy code dates back 15 years or more to numeric. I doubt whoever originally wrote it thought much about it, but there may be some good reason, and there is the safety considerations that people use the strides in a way they should not, which may trip us here in any case. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22445 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22458] Add fractions benchmark
Stefan Behnel added the comment: I admit that I keep meeting developers who are not aware of their merits, simply because many other programming languages don't have them available. Specifically, many developers with a Java background firmly believe that BigDecimal is the only way to do money calculations. That's clearly wrong, and the heap of (Big-)Decimal bugs in their software that I've been fixing over the years shows just how wrong it is. Using Fractions would have avoided most of them. Decimal is surprisingly difficult to use right, Fractions are actually difficult to get wrong. They are a major feature of the standard library. Your question is another good indication that the general awareness for them still needs to be raised. I'm not entirely sure how this relates to this ticket, though. I doubt that you are seriously suggesting that I am the only person using a module in the stdlib, so what exactly are you trying to say? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22458 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Probably exactly the same as they do right now. I think there's an argument
that `float('inf') // 1` should have been `float('inf')`. But I'm not sure
there's much of a case for *changing* the current return value.

Unfortunately, I don't have the right setup currently to look into it further, but my best guess would be that perhaps the pydoc-topics Sphinx builder needs an update for Python 3? -- nosy: +zach.ware ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22461 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Mark,
Raymond suggested that The PEP 3141 should be revised to say that floor
division is defined to return a value that is *equal* to an Integral.
Since nan or inf are not *equal* to any Integral, the current implementation
does not comply. In the absence of a recommendation in the PEP, implementers
of new numeric types are left with little guidance because existing types are
inconsistent:

[issue22198] Odd floor-division corner case
Alexander Belopolsky added the comment: I wonder if it would make sense to rewrite float_divmod using the newer POSIX/C99 remquo function. I believe it is designed to compute the exact value of round(x/y), but getting floor instead should not be hard. Its behavior on special values is fully specified. From the Linux man-page (I believe POSIX/C99 only guarantees 3 bits in quo): NAME remquo -- floating-point remainder and quotient function SYNOPSIS #include math.h double remquo(double x, double y, int *quo); long double remquol(long double x, long double y, int *quo); float remquof(float x, float y, int *quo); DESCRIPTION The remquo() functions compute the value r such that r = x - n*y, where n is the integer nearest the exact value of x/y. If there are two integers closest to x/y, n shall be the even one. If r is zero, it is given the same sign as x. This is the same value that is returned by the remainder() function. remquo() also calculates the lower seven bits of the integral quotient x/y, and gives that value the same sign as x/y. It stores this signed value in the object pointed to by quo. SPECIAL VALUES remquo(x, y, quo) returns a NaN and raises the invalid floating-point exception if x is infinite or y is 0. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22198 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22433] Argparse considers unknown optional arguments with spaces as a known positional argument
paul j3 added the comment:
Proposed patches like this are supposed to be generated against the current
development version (3.5...), especially if they are 'enhancements' (as opposed
to bugs). But there isn't much of a difference in argparse between 2.7+ and
3.4+ (except one nested yield expression).
Tests are in 'lib/test/...'
argparse does implement the '--' syntax. That is, anything after it is
understood to be positional, regardless of its prefix characters. But before
that, optionals and positionals can be freely mixed (within limits).
I agree that '--foo=one two' looks a lot more like an unknown optional than the
test case 'a badger'. Strings with '=' are tested earlier in _parse_optional.
A fix that passes test_argparse.py and your example is:
if '=' in arg_string:
option_string, explicit_arg = arg_string.split('=', 1)
if option_string in self._option_string_actions:
action = self._option_string_actions[option_string]
return action, option_string, explicit_arg
else: # added for unrecognized
return None, option_string, explicit_arg
# or return None, arg_string, None
But the '=' case is also tested in the following line:
option_tuples = self._get_option_tuples(arg_string)
The obvious difference is that _get_option_tuples handles abbreviations.
I wonder if the two can be refined to reduce the duplication, and handler your
case as well.
There are other bug issues dealing with multiple '--', the mixing of optionals
and positionals, and controlling whether abbreviations are allowed or not. I
don't recall any others dealing with strings that contain '=' or space.

[issue22467] Lib/http/server.py, inconsistent header casing
New submission from DS6: Inconsistent casing, such as Content-type vs Content-Type, Content-Length vs Content-length, while technically not breaking any RFC or other HTTP-related rules (headers are case-insensitive, after all), can occasionally cause problems when attempting to retrieve already-set headers from http.server.BaseHTTPRequestHandler._headers_buffer (in my situation specifically, trying to retrie the Content-Type header in the sendfile method in an extended BaseHTTPRequestHandler class). This happens a lot in the file and I wouldn't be surprised if the problem were to crop up in other places as well. I'm a new user of Python, so despite having searched for an answer to this problem, if there's a case-insensitive way to obtain items from a list and I'm just daft, please feel free to point me in the right direction, though I feel that the casing should be corrected regardless for consistency and optimization sake. (Aside: I would try to publish a patch along with this issue report with the casing issues fixed, but I'm not too knowledgeable about versioning and stuff and would have no idea where to start.) -- components: Library (Lib) messages: 227324 nosy: DS6 priority: normal severity: normal status: open title: Lib/http/server.py, inconsistent header casing versions: Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22467 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22467] Lib/http/server.py, inconsistent header casing
Senthil Kumaran added the comment: First thing (and the easiest is), if you find inconsistent casing in http/server.py itself, then make it consistent in your patch against cpython default branch (from hg.python.org). Make it Content-Length and Content-Type in your patch. Next part is while receiving the request with these headers, the client and server should store it in case-insensitive dict (there is open request and patch, which can churn up again and we can fix it as part of that issue). -- nosy: +orsenthil ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22467 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22467] Lib/http/server.py, inconsistent header casing
DS6 added the comment: Erp, *retrieve, and I meant copyfile, not sendfile. I'm tired. Very quick reply, by the way. I suppose I forgot to mention that _headers_buffer is for sending headers, not for receiving them. As far as I can read, the received header information is already case-insensitive, due to email.message.Message being used. It also occurs to me that the _headers_buffer field probably wasn't designed to be directly accessed, seeing as how it's usually flushed immediately after being modified... -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22467 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
