[issue19861] Update What's New for Python 3.4
yegle added the comment: Hi all, It's my first time commenting on this issue tracker so bear with me if this looks naive. For the `plistlib` package, from Apple's own manual[1], there's actually a third JSON format. It'll be good to indicate that `plistlib` doesn't support JSON format in the what's new page and corresponding document page. It takes me sometime before I realize `plistlib` in Python 3.3 doesn't support the so called binary property list format. So if the JSON format won't be supported in this Python version, it'll save someone's time by just reading the manual.

Ethan Furman added the comment: Thank you everyone for increasing my understanding. :) Terry J Reedy wrote: [snip everything I now agree with, which is most of Terry's comment] 3. Every core usage of __int__ looks for __index__ also. Int() does not do this now, but '%d' does [...] The exact details would depend on whether we want to allow (or at least bless) classes with __int__ and __index__ returning different ints. I think we should state that __int__ and __index__ are expected to return the same value (if both are defined) otherwise one is on one's own (otherwise known as: if it breaks, you own all the pieces ;) . Given things as they are, I would simply expand the domain of %x, etc, to that of %d without bothering to go through a deprecation process. This is not correct. `hex(3.14)` raises a TypeError, and so should `'%x' % 3.14` While Terry's option 2 would have to wait for 3.5, is there any reason why fixing the %-formating characters to use __index__ instead of __int__ can't go into 3.4?

That's weird. I ran the same test on the same computer with an installed
64-bit 3.3.2, and got the same results (70+% failure). I just ran the same
test on a different computer (32-bit Windows 7), and also got the same results
with both 3.4.0b1+ and 3.3.2 (installed).
FTR:
time.get_clock_info('monotonic')
namespace(adjustable=False, implementation='GetTickCount64()', monotonic=True,
resolution=0.0156000999)
I believe it's the same for all four Pythons tested.
Shall I open a new issue for this, or is it related enough to stay here? :)

[issue19999] test_monotonic fails on x86 OpenIndiana
Tim Peters added the comment:
Hmm. One obvious difference on my box:
Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:03:43) [MSC v.1600 32 bit
(Intel)] on win32
time.get_clock_info('monotonic')
namespace(adjustable=False, implementation='GetTickCount64()', monotonic=True,
resolution=0.015625)
So the resolution here is exactly 1/64. If that's truly the resolution, then
all the results I'll see are exactly representable as Python floats.
The resolution you see (0.0156000999) looks bizarre. Not because of
the trailing nines, but because 0.0156001 doesn't appear to have any natural
hardware or software meaning in decimal or binary.
That said, I see we get the resolution from GetSystemTimeAdjustment. I don't
understand the Windows time functions, but also don't see anything in the MSDN
docs to suggest that the results from GetSystemTimeAdjustment should have
anything to do with the resolution of GetTickCount64. But maybe they do - LOL
;-)
One other point: we have lots of code of the form:
info-resolution = timeIncrement * 1e-7;
That is, we multiply some integer type by a double _negative_ power of 10. All
such code is needlessly inaccurate: no negative power of 10 is exactly
representable as a double, so we suffer a rounding error in representing 1e-7,
and then another rounding error from the multiplication. It's trivial to
reduce the grand total to one rounding error instead, by rewriting as:
info-resolution = timeIncrement / 1e7;
But these rounding errors are too tiny to account for the difference between,
e.g., 0.499000107102 and 0.5.
I don't conclude that we don't know what we're doing, but I bet we don't really
understand what Windows is doing ;-)

[issue20057] wrong behavior with fork and mmap
New submission from Brett Tiplitz: When running the example mmap library (with a slight modification, plus I did not handle all the changes for the 3.3 string handling as the example posted does not work with 3.x) When looking at the subprocess, the spawned process will have all the mmap'd file descriptors open. The spawned process has the responsibility of closing any FD's that are in use. However, since the shared memory segment get's closed and the program has no knowledge of private FD's, the mmap's private FD becomes a leak in the FD table. It seems python should set the close-on-exec attribute on the dup'd FD that it maintains. Examples of fixing this issue are found on http://stackoverflow.com/questions/1643304/how-to-set-close-on-exec-by-default import mmap,os # write a simple example file with open(hello.txt, wb) as f: f.write(bytes(Hello Python!\n, 'UTF-8')) with open(hello.txt, r+b) as f: # memory-map the file, size 0 means whole file os.system(/bin/ls -l /proc/+str(os.getpid())+/fd) mm = mmap.mmap(f.fileno(), 0) os.system(/bin/ls -l /proc/+str(os.getpid())+/fd) os.system(/bin/ls -l /proc/self/fd) # read content via standard file methods t1 = mm.readline() # used to print out # prints Hello Python! # read content via slice notation t2=mm[:5] #print mm[:5] # prints Hello # update content using slice notation; # note that new content must have same size mm[6:] = bytes( world!\n, 'UTF-8') # ... and read again using standard file methods mm.seek(0) t3=mm.readline() # print mm.readline() # prints Hello world! # close the map mm.close() ~ -- components: Library (Lib) messages: 206871 nosy: btiplitz priority: normal severity: normal status: open title: wrong behavior with fork and mmap type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20057 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19999] test_monotonic fails on x86 OpenIndiana
STINNER Victor added the comment: For more info on time, you can refer to the PEP 418. I may be interesting to add sleep to time.get_clock_info(). time.sleep() uses WaitForSingleObject() on windows. It may use internally a different clock with a different resolution than time.monoyonic (GetTickCount). The PEP says WaitForSingleObject(): use the same timer than GetTickCount() with the same precision. I don't think that it's very useful to investigate the rounding issue on Windows. The resolution of Windows clocks is very coarse (15 ms, 10^-2) compared to Unix clocks (usually a few nanoseconds, 10^-9)... I changed recently the unit test to check if a sleep of 0.5 seconds gives a time delta of at least 0.5 seconds.

Brett Tiplitz added the comment: Man page currently says as follows: (this does not says it's deprecated or that files have to be closed on exec)... So I'd think some more comments would help. And as mentioned, which a user can close his own fd's, the mmap call creates a special problem since the user can't work around the issue cleanly though fixed in the subprocess calls. s.system(command) Execute the command (a string) in a subshell. This is implemented by calling the Standard C function system(), and has the same limitations. Changes to sys.stdin, etc. are not reflected in the environment of the executed command. On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent. On Windows, the return value is that returned by the system shell after running command, given by the Windows environment variable COMSPEC: on command.com systems (Windows 95, 98 and ME) this is always 0; on cmd.exe systems (Windows NT, 2000 and XP) this is the exit status of the command run; on systems using a non-native shell, consult your shell documentation. The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function.

[issue20058] IDLE's shell returns a multiple-line string to input() or readline() when multiple lines of text are pasted by the user
New submission from Steven Barker: Pasting multiple lines of input and then pressing Enter when IDLE is waiting to read a single line (such as when input() or sys.stdin.readline() have been called) will result is a multi-line string being given as the input, rather than a single line. This may be most easily understood by looking at an example. Run this code in IDLE (either by typing it in the shell, or from a file with F5): s = X while s: s = input() print(repr(s)) First, try typing in several lines. Each will be printed separately, with no newlines inside the strings (since input() strips a trailing newline). foo 'foo' bar 'bar' baz 'baz' Next, copy several lines of text from somewhere. It doesn't matter what the lines' contents are. Here I grabbed a list of Python version numbers, as I was on the download page after grabbing 3.4.0b1 for testing this bug: 3.1.5 3.0.1 2.7.6 2.6.9 2.5.6 2.4.6 2.3.7 2.2.3 all the preceding lines were pasted in one go, followed by enter pressed here '3.1.5\n3.0.1\n2.7.6\n2.6.9\n2.5.6\n2.4.6\n2.3.7\n2.2.3' This behavior is different than what the Python interpreter does in a regular console shell. When running in cmd.exe on Windows, Python treats a multi-line paste just like typed input: 3.1.5 '3.1.5' 3.0.1 '3.0.1' 2.7.6 '2.7.6' 2.6.9 '2.6.9' 2.5.6 '2.5.6' 2.4.6 '2.4.6' 2.3.7 '2.3.7' 2.2.3 enter typed here '2.2.3' I expect the same behavior will be common in other kinds of terminals on other platforms. This issue makes testing certain kinds of programs very frustrating. If your program needs to read certain text from STDIN, and you want to paste that text in quickly, you need to update your code with special logic just for use in IDLE's console. As an example of the kind of pain you may experience, try copying and pasting a block of text with a blank line into the input loop above. On a regular console session it will exit the loop after the blank line. In IDLE, it will keep running. I've traced the source of this issue through IDLE's sys.stdin file object and an RPC call, and found it probably is located in the idlelib.PyShell.PyShell.readline method (or the surrounding code). This grabs a string from the Text object in the shell window and returns it to the Python code running in the subprocess. Probably it should have some extra steps added to check if it got multiple lines. If so, it should split the string on newlines and return just one line of text for each readline call. I'm not sure exactly what should be done with the rest of the lines, but perhaps they could be queued up (or somehow put back by moving the markers in the Text object) so later lines would be grabbed by later input requests. Or alternatively, maybe the event where the multi-line paste arrives should be handled differently, as several single-line input events, rather than a single multiple-line one. -- components: IDLE messages: 206879 nosy: Steven.Barker priority: normal severity: normal status: open title: IDLE's shell returns a multiple-line string to input() or readline() when multiple lines of text are pasted by the user type: behavior versions: Python 2.7, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20058 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20059] Inconsistent urlparse/urllib.parse handling of invalid port values?
New submission from Chad Birch: I'm not sure if this is something that needs adjustment, but it seems somewhat inconsistent to me. After using urlparse() on various urls with invalid port values, trying to access .port on the result will raise a ValueError. This case includes urls such as: http://www.example.com:asdf; http://www.example.com:1.5; http://www.example.com:; However, as of May 24 2012 (http://hg.python.org/cpython/diff/d769e64aed79/Lib/urllib/parse.py), if the invalid port value is an integer, accessing .port will result in None. So this includes urls such as: http://www.example.com:66000; http://www.example.com:-1; Should these two cases be made consistent, so that either .port is always None or always results in a ValueError if the port section of the url is invalid? I'd be happy to write a patch for it if it's wanted, but I thought I'd check first (and see which of the two options would be correct, if so). -- components: Library (Lib) messages: 206881 nosy: chad.birch priority: normal severity: normal status: open title: Inconsistent urlparse/urllib.parse handling of invalid port values? type: behavior ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20059 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19999] test_monotonic fails on x86 OpenIndiana
Tim Peters added the comment: @haypo, I've read the PEP and it has great ideas. What I'm wondering is whether they've been implemented correctly in the relevant cases on Windows here. That Zach see a resolution of 0.0156001 on Windows isn't plausibly a question of rounding errors: that value appears to be insane. Yes, it's vaguely close to the 0.015625 I see, but the value I see _is_ sane (being exactly 1/64) - but 0.0156001 isn't close enough to 0.015625 for rounding errors to be at all a plausible explanation for why it's so strange. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20054] IDLE won't work (Mac)
Ned Deily added the comment: This problem was reported and fixed in Issue18270 which will be in the next set of Python maintenance releases. As explained there, what is causing this is that the Python 3.3 tkinter you are using is trying to use the known buggy system Tk 8.5 shipped with OS X. If you are using a python.org 3.3, you can avoid the problem by installing a more up-to-date version of Tcl/Tk 8.5, such as the current ActiveTcl 8.5.15.0.
