[issue13453] Tests and network timeouts

Dict.update documentation bug
The current docstring for dict.update shows:
help(dict.update)
Help on method_descriptor:
update(...)
D.update(E, **F) - None. Update D from dict/iterable E and F.
If E has a .keys() method, does: for k in E: D[k] = E[k]
If E lacks .keys() method, does: for (k, v) in E: D[k] = v
In either case, this is followed by: for k in F: D[k] = F[k]
Better, would be something like:
update(...)
D.update(E=None, **F) - None. Update D from dict/iterable E and F.
If E is not None then:
If E has a .keys() method, does: for k in E: D[k] = E[k]
If E lacks .keys() method, does: for (k, v) in E: D[k] = v
In either case, this is followed by: for k in F: D[k] = F[k]
The current signature states that argument E is mandatory, when it is
not.
eg.
d = {}
d.update(mykey={1:2}) # just keywords passed in, no E
I tried subclassing the builtin dict using the current signature as a
guide,
but my implementation was incorrect since I had assumed there was a
mandatory
argument, E.

Gerrat

[issue10408] Denser dicts and linear probing
Charles-François Natali neolo...@free.fr added the comment: This paper might be of interest: http://www.siam.org/meetings/alenex05/papers/13gheileman.pdf Basically, it concludes that most of the time, there's no speedup to be gained from the increased cached locality incurred by linear probing when the input sample differ from a uniform distribution. However, figure 1 shows a clear win with a uniform distribution, and figure 2 shows that even with a non-uniform distribution, there's still a gain as the load factor increases. So if experiments show measurable improvements, this might be an interesting idea. However, the problem with linear probing is that the performance will be much more dependent on the input distribution that with quadratic probing/double hashing, so this will definitely degrade with some workloads. The problem with linear probing, as noted in the comments, is that it degrades performance quite a lot when the hashing function clusters results. The solution I'm proposing is to apply an *initial* perturbation, by multiplying the hash() with a prime number. I fail to see how this would avoid primary clustering: IIUC, you replace the hash function h(k) by h'(k), but you still use linear probing: an empty slot preceded by i filled slots has a probablility (i+1)/N of getting filled next (N being the total number of slots). -- nosy: +neologix ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10408 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13570] Expose faster unicode-ascii functions in the C-API
STINNER Victor victor.stin...@haypocalc.com added the comment:
Le 09/12/2011 22:12, Stefan Krah a écrit :
The bottleneck in _decimal is (res is ascii):
PyUnicode_FromString(res);
PyUnicode_DecodeASCII(res) has the same performance.
With this function ...
static PyObject*
unicode_fromascii(const char* s, Py_ssize_t size)
{
PyObject *res;
res = PyUnicode_New(size, 127);
if (!res)
return NULL;
memcpy(PyUnicode_1BYTE_DATA(res), s, size);
return res;
}
... I get the same performance as with Python 2.7 (5.85s)!
The problem is that unicode_fromascii() is unsafe: it doesn't check
that the string is pure ASCII. That's why this function is private.
Because of the PEP 383, ASCII and UTF-8 decoders (PyUnicode_DecodeASCII
and PyUnicode_FromString) have to first scan the input to check for
errors, and then do a fast memcpy. The scanner of these two decoders is
already optimized to process the input string word by word (word=the C
long type), instead of byte by byte, using a bit mask.
--
You can write your own super fast ASCII decoder using two lines:
res = PyUnicode_New(size, 127);
memcpy(PyUnicode_1BYTE_DATA(res), s, size);
(this is exactly what unicode_fromascii does)
I think it would be really beneficial for C-API users to have
more ascii low level functions that don't do error checking and
are simply as fast as possible.
It is really important to ensure that a ASCII string doesn't contain
characters outside [U+; U+007F] because many operations on ASCII
string are optimized (e.g. UTF-8 pointer is shared with the ASCII pointer).
I prefer to not expose such function or someone will use it without
understanding exactly how dangerous it is.
Martin and other may disagree with me.
Do you know Murphy's Law? :-)

[issue13570] Expose faster unicode-ascii functions in the C-API
Stefan Krah stefan-use...@bytereef.org added the comment:
I prefer to not expose such function or someone will use it without
understanding exactly how dangerous it is.
OK. - I'm afraid that I made an error in the benchmarks, since I
accidentally used a changed version of telco.py, namely:
# t is a Decimal
outfil.write(%s\n % t) # original version
...
outfil.write(str(t)) # changed version runs
outfil.write('\n') # faster since PEP-393
...
Since PEP-393 the changed version with two calls to write()
runs quite a bit faster than the original. For Python-3.2
and 2.7 the original runs faster.
Do you have an idea what could cause this?

[issue13525] Tutorial: Example of Source Code Encoding triggers error
Éric Araujo mer...@netwok.org added the comment: Thanks for the detailed bug report. I thought the normalization performed by the codec lookup system would convert 'cp-1252' to 'cp1252' (its “real” name, i.e. the name of the module implementing the codec), but it does not. I’m +1 to removing the hyphen in the example, then. Python raises the following exception: SyntaxError: encoding problem: with BOM I reproduced this and it’s surprising.

[issue13537] Namedtuple instances can't be pickled in a daemonized process
Éric Araujo mer...@netwok.org added the comment:
Confirmed (3.2):
def func():
... t = collections.namedtuple('t', 'a')
... instance = t(1)
... print(instance)
... return pickle.dumps(instance)
func()
t(a=1)
Traceback (most recent call last):
File stdin, line 1, in module
File stdin, line 5, in func
_pickle.PicklingError: Can't pickle class '__main__.t': attribute lookup
__main__.t failed
We may open an enhancement request to suggest that the error message include
the qualname, but otherwise this is not a bug.

[issue13538] Docstring of str() and/or behavior
Éric Araujo mer...@netwok.org added the comment: A note in the docs (without note/warning directives, just a note) and maybe the docstring would be good. It should better explain that str has two uses: converting anything to a str (using __str__ or __repr__), decode buffer to str (with encoding and errors arguments). str(b'') is a case of the first use, not the second (and likewise %s formatting). -- nosy: +eric.araujo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13538 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13550] Rewrite logging hack of the threading module
Éric Araujo mer...@netwok.org added the comment: On #13550 I asked Guido about the Thing/_Thing function/class indirection and use of _Verbose; the reply: IIRC: The design started out this way because it predates new-style classes. When this was put in one couldn't subclass extension types, and there were plans/hopes to replace some of the lock types with platform-specific built-in versions on some platforms. Since it is now possible to write subclassable extension types the Thing/_Thing design is no longer needed. I'm not sure about the _Verbose hacks, if it is deemed not useful I'm fine with letting it go. -- nosy: +eric.araujo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13550 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13549] Incorrect nested list comprehension documentation
Ezio Melotti ezio.melo...@gmail.com added the comment: Having both is fine. I just noticed that the 3.2 docs are different[0], so I tried to merge them: 3.2 says: List comprehensions provide a concise way to create lists from sequences. Common applications are to make lists where each element is the result of some operations applied to each member of the sequence, or to create a subsequence of those elements that satisfy a certain condition. I kept this, changing a few minor things. In 3.2 the examples are divided and each one has a short description. I reworked them a bit to make them more clear, and added the description inline as a comment. The section about nested listcomps is the same, so I didn't change it (but it's now a subsection of the list comprehension section). This is hopefully the final version.

[issue13568] sqlite3 convert_date error with DATE type
Filip Gruszczyński grusz...@gmail.com added the comment:
c.execute(insert into testdate values ('now'))
This works, but you actually are putting string now into a field with DATE
type. When conversion occurs after retrieving data, there is an error. Also if
you use datetime() function
c.execute(insert into testdate values (datetime()))
you'll get an error later during conversion, because python expects date string
and will get datetime string. This should work for you:
c.execute(insert into testdate values (date()))
x = c.execute(select * from testdate)
for a in x:
... print(a)
...
(datetime.date(2011, 12, 10),)

[issue11822] Improve disassembly to show embedded code objects
Torsten Landschoff t.landsch...@gmx.net added the comment:
I offer the attached patch as a starting point to fulfill this feature request.
The patch changes the output to insert the disassembly of local code objects on
the referencing line.
As that made the output unreadable to me, I added indentation for the nested
code (by 4 spaces, hoping that nobody will nest code 10 levels deep :-)
This results in the following output for the original example:
from dis import dis
dis('[x**2 for x in range(3)]')
1 0 LOAD_CONST 0 (code object listcomp at
0x7f24a67dde40, file dis, line 1)
1 0 BUILD_LIST 0
3 LOAD_FAST0 (.0)
6 FOR_ITER16 (to 25)
9 STORE_FAST 1 (x)
12 LOAD_FAST1 (x)
15 LOAD_CONST 0 (2)
18 BINARY_POWER
19 LIST_APPEND 2
22 JUMP_ABSOLUTE6
25 RETURN_VALUE

[issue13569] Loggers cannot be pickled
Vinay Sajip vinay_sa...@yahoo.co.uk added the comment: You shouldn't need to pickle loggers, because loggers just represent where in your application something happens (that being determined by the logger name). The logger name is just a string, and if you need to communicate that across e.g. a process boundary, just sending the name should be enough. Ideally in a multiprocessing application, logging initialisation should happen after the fork() or CreateProcess() which creates the child process. It's best if loggers are named after the module which logs events (using __name__, which means you don't need to pass the name around - but even if you need to for some reason, you still don't need to pickle a logger or pass it around as a parameter). You *can* use logging safely in terms of the locks it creates to serialise access to I/O resources and to protect shared data structures, but you still need to understand what's happening and allow for it in your own coding. To summarise, I don't quite see from the information in this issue why it is desirable to pickle loggers, and the GitHub link doesn't work, so I can't look at Nikita's example, either. So if a better justification isn't available, I would like to close the issue. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13569 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13576] Handling of broken condcoms in HTMLParser
New submission from Ezio Melotti ezio.melo...@gmail.com: The attached patch adds a few tests about the handling of broken conditional comments (condcoms). A valid condcom looks like !--[if ie 6]...![endif]--. An invalid one looks like ![if ie 6]...![endif]. This seems a common mistake, and it's found even on popular sites like adobe, linkedin, deviantart. Currently, HTMLParser calls unknown_decl() passing e.g. 'if ie 6', and if strict=True an error is raised. With strict=False no error is raised and the unknown declaration is ignored. The HTML5 specs say: [After '!',] If the next two characters are both U+002D HYPHEN-MINUS characters (-), consume those two characters, [...] Otherwise, this is a parse error. Switch to the bogus comment state.[0] [Once in the bogus comment state,] Consume every character up to and including the first U+003E GREATER-THAN SIGN character () or the end of the file (EOF), whichever comes first. Emit a comment token whose data is the concatenation of all the characters starting from and including the character that caused the state machine to switch into the bogus comment state, up to and including the character immediately before the last consumed character (i.e. up to the character just before the U+003E or EOF character), but with any U+ NULL characters replaced by U+FFFD REPLACEMENT CHARACTER characters. (If the comment was started by the end of the file (EOF), the token is empty.)[1] So, IIUC, '![if ie 6]...![endif]' should emit a '[if ie 6]' comment, parse the '...' normally, and emit a '[endif]' comment. However I think it's fine to leave the current behavior for the following reasons: 1) backward compatibility; 2) handling broken condcoms in unknown_decl is easier than doing it in handle_comment, where all the other comments are sent; 3) no one probably cares about them anyway; [0]: http://www.w3.org/TR/html5/tokenization.html#markup-declaration-open-state [1]: http://www.w3.org/TR/html5/tokenization.html#bogus-comment-state -- assignee: ezio.melotti components: Library (Lib) files: issue13576.diff keywords: patch messages: 149204 nosy: eric.araujo, ezio.melotti priority: normal severity: normal stage: commit review status: open title: Handling of broken condcoms in HTMLParser type: behavior versions: Python 2.7, Python 3.2, Python 3.3 Added file: http://bugs.python.org/file23909/issue13576.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13576 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Nick Coghlan ncogh...@gmail.com: subprocess.check_output() is nice, but doesn't help if you want to process the piped data line-by-line. Currently, that means you have to do the full Popen dance if you want access to each line of output as it becomes available. This RFE is for a subprocess.iter_output() module level helper that: 1. Starts the subprocess 2. Yield the individual lines of output as they are produced by the subprocess 3. Cleans up (including checking for errors) at the end This biggest challenge I have noticed so far in exploring this is how to handle timeouts on Windows - on Unix, select.select() can do the job, but that won't handle pipes in the Windows case. -- components: Library (Lib) messages: 149210 nosy: ncoghlan priority: normal severity: normal stage: needs patch status: open title: Add subprocess.iter_output() convenience function type: feature request versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13578 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13405] Add DTrace probes
Jesús Cea Avión j...@jcea.es added the comment: Pending work yet: (documented to avoid forgeting it) - Performance hit because trying to determine the source line in each function call. To be solved with ¿tolerable? memory overhead. Would be acceptable to sacrifice x2/x4 time the pyc filesize (in memory) in order to avoid any runtime performance hit?. That is, a million bytecodes (not a bad program size) could need 2/4 MB. I think it is a good investment if DTRACE becomes performance-transparent. - Build procedure is flaky. I am asking DTrace developers. - DTRACE/GCC offset/bitmasks doesn't coincide. Instead of wiring offsets manually, they should be detected at compile time, automatically. - Add new probes. Suggestions?. What do you want to instrumentalize?. I am thinking about the GIL, module import - Try the code with clang instead of GCC. - Address pending review comments done by Martin v. Löwis. - Use PEP 3155. - Trace C function calls/returns, not only Python ones. The problem here is to know the name of the function, because we can call it in a million different ways.
