[issue12211] Better document math.copysign behavior.
Sandro Tosi sandro.t...@gmail.com added the comment:
Taken from
http://www.slac.stanford.edu/comp/unix/package/rtems/doc/html/libm/libm.info.copysign.html
i'd suggest to extend
Return a float with the magnitude of x
to
Return a float with the magnitude (absolute value) of x
It could probably help people less math-savvy in understand what's going to
happen :)
Maybe also (only in rest doc) might be nice to describe what happens in case
the arguments are NaN, f.e.:
import math
x = float('nan')
math.copysign(1., x)
1.0
math.copysign(-1., x)
1.0
math.copysign(x, -1)
nan
math.copysign(x, x)
nan
umedoblock: would you like to expand the patch with these notes (unless someone
objects :)).

While not just something like: While True: try: block = list.pop() except IndexError: break _free(block) Lock-less lists are not strictly atomic (only on cPython), but I doubt that gc.disable() is available and works on every Python interpreter anyway... So the idea would be: - in free(), perform a trylock - if trylock fails, append the block to a list of pending blocks to free - if trylock succeeds, free the pending blocks and proceed as usual (do the same thing in malloc()) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12352 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12413] make faulthandler dump traceback of child processes
Charles-François Natali neolo...@free.fr added the comment: You mean that the tracebacks of children should be dumped on a timeout of the parent? Or do you also want them on a segfault of the parent? In my experience, the most common problem with the multiprocessing and subprocess modules is the hang. Well, a segfault is due to the current process (or sometimes to external conditions like OOM, but that's not the point here), so it's not really useful to dump tracebacks of child processes in that case. I was more thinking about timeouts. The timeout is implemeted using a (C) thread in faulthandler. You can do more in a thread than in a signal handler ;-) A hook may be added to faulthandler to execute code specific to multiprocessing / subprocess. Yes, but when the timeout expires, there's no guarantee about the state of the interpreter (for example in issue #12352 it was the GC that deadlocked), so I guess we can't do anything too fancy. In which case is Python the leader of the group? Is it the case by default? Can we do something to ensure that in regrtest, in multiprocessing tests or the multiprocessing module? Yes, it's the case by default when you launch a process through a shell. The subprocess maintains a list of the create subprocesses: subprocess.alive, but you need a reference a reference to this list (or you can access it using the Python namespace, but it requires the GIL and you cannot trust the GIL on a crash). Does multiprocessing maintain a list of child processes? Yes, we don't have any guarantee about the interpreter's state, and furthermore this won't work for processes calling fork() directly. subprocess can execute any program, not only Python. Send an arbitrary signal to a child process can cause issues. Well, faulthandler is disabled by default, no ? By the way, which signal do you want to send to the child processes? A test may replace the signal handler of your signal (most test use SIGALRM and SIGUSR1). Hum, SIGTERM maybe? Don't you register some fatal signals by default? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12413 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Stefan Krah stefan-use...@bytereef.org added the comment: [Nick] Another idea we may want to revisit is the PyManagedBuffer concept, which would be a true PyObject that existed solely to simplify sharing of Py_buffer structs. If memoryview used such an object internally, then copying and slicing would be quite simple - just INCREF the managed buffer instance without letting the original source object know anything was going on. I think this is the nicest solution since memoryview would then always have a proper base object. Do I understand correctly that PyManagedBuffer should only handle 1-dimensional objects? There is an additional point about slicing and sub-views: I think slicing (esp. multidimensional slicing) would be greatly simplified if we added a requirement for the *exporting* object to provide a sliced view. (The same applies to sub-views, also see source comments below [1]). For example, an exporting object could provide a sliced view by adding a getslicedbufferproc to PyBufferProcs: int PyObject_GetSlicedBuffer(PyObject *obj, Py_buffer *view, int flags, PyObject *key); By sliced view I mean that the exporting object changes buf, shape and strides. There are several advantages: o The invariant that all allocated memory in the buffer belongs to the exporting object remains intact. o The responsibility for creating correct multidimensional sliced views is shifted to the implementor of the exporting object.

[issue11253] autodocument first appearance of ctypes.wintypes constants
Mark Mc Mahon mtnbikingm...@gmail.com added the comment:
This mostly a documentation concern - correct? ctypes.wintypes is sparsely
documented - in 2.7 the help for it seems to be:
The ctypes.wintypes module provides quite some other Windows specific data
types, for example HWND, WPARAM, or DWORD. Some useful structures like MSG or
RECT are also defined.
How about the following solution:
First of all get the previous release information
- hg log / hg revert / import wintypes / dir(wintypes)
Future changes have to be updated manually (which probably is not a big deal as
it is a reasonably stable module)
In fact I went and got the revision when each attribute was added... (some of
those are just ctypes leakage)

[issue11457] Expose nanosecond precision from system calls
Martin v. Löwis mar...@v.loewis.de added the comment: any broken-down time has issues of time stamp ordering in the duplicate hour of switching from DST to normal time I understand that it is an issue of the datetime module. Can it be solved, or is there a design issue in the module? It's an inherent flaw of broken-down time. Don't use that representation; the only true representation of point-in-time is seconds since the epoch, as a real number (IMO, of course). Broken-down time has the advantage of being more easily human-readable, but is (often deliberately) incomplete (with the notion of partial time stamps) and text representations are difficult to parse. I don't have a strong opinion on this issue, I just wanted to know why datetime cannot be used for this issue. It's a personal preference of me (the strong objection to broken-down time representations). I believe this preference is widely shared, though. Notice how advanced file systems (NTFS, ext2) use seconds-since- the-epoch formats, whereas FAT uses broken-down time. Also notice how the daytime protocol uses broken-down time, and NTP uses seconds-since-the epoch. The major variation point in the latter is whether second fractions are represented as a separate number of not; this is also the issue here. NTP and NTFS use a single number; ext2 uses seconds/nanoseconds. Also notice that NTP does *not* have a unit that is an integral power of ten, but units of 2**-32s (ca. 233ps). NTP4 supports a resolution of 2**-64s. (To be fair, the way NTP represents time stamps can also be interpreted as a pair of second/subsecond integers). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11457 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Nick Coghlan ncogh...@gmail.com added the comment: The idea of PyManagedBuffer is for it to be an almost completely passive object that *just* acts as a refcounted wrapper around the Py_buffer structure, so it doesn't care about the actual contents. The only supplemental functionality I think it should provide is to disallow explicitly releasing the buffer while the reference count is greater than 1. I'm OK with my example cited above being unreliable. The correct way to write such code would then be: with memoryview(obj) as m: with m[:] as m2: ... I think separating the concerns this way, letting PyManagedBuffer worry about the lifecycle issues of the underlying buffer reference, while PyMemoryView deals with the *interpretation* of the buffer description (such as by providing useful slicing functionality) will make the whole arrangement easier to handle. When a memoryview is sliced, it would create a new memoryview that has a reference to the same PyManagedBuffer object, but different internal state that affects how that buffer is accessed. This is better than requiring that every implementor of the buffer API worry about the slicing logic - we can do it right in memoryview and then implementers of producer objects don't have to worry about it. Currently, however, memoryview gets tied up in knots since it is trying to do everything itself in a way that makes it unclear what is going on. The semantics of copying the Py_buffer struct or of accessing the PEP 3118 API on the underlying object when slicing or copying views are demonstrably broken. If we try to shoehorn reference counting semantics into the current object model, we would end up with two distinct modes of operation for memoryview: Direct: the view is directly accessing an underlying object via the PEP 3118 API Indirect: the view has a reference to another memoryview object that it is using as a data source That's complicated - hard to implement in the first place and hard to follow when reading the code. Adding the PyManagedBuffer object makes the object model more complex, but simplifies the runtime semantics: every memoryview instance will access a PyManagedBuffer object which takes care of the underlying PEP 3118 details. Direct use of the PEP 3118 consumer API in 3rd party code will also be strongly discouraged, with PyManagedBuffer promoted as the preferred alternative (producers, of course, will still need to provide the raw Py_buffer data that PyManagedBuffer exposes). At the Python level, I don't think it is necessary to expose a new object, so we can stick with Antoine's preferred model where memoryview is the only public API. My proposed new PyManagedBuffer object would just be about making life easier at the C level. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Nick Coghlan ncogh...@gmail.com added the comment: I should also note that if memoryview ends up growing enough state to cope correctly with numpy-style multi-dimensional slicing, I'm actually OK with that. You could get a long way just using the array module to allocate a large chunk of memory and then a suitably enhanced memoryview to manipulate it as a multidimensional array. That's a future concern, though - for now, the key task is to migrate to reliable, reference based semantics for Py_buffer management. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10181 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1067702] urllib fails with multiple ftp transfers
Stefan Schwarzer sschwar...@sschwarzer.net added the comment: I was able to get some error output with the code of the OP. However, I only saw the opposite message, such as: Retrieval of 'ftp://ftp.gnome.org/pub/debian/dists/stable/main/source/Sources.bz2' failed with error: [Errno ftp error] 200 Switching to Binary mode. I had to change the used FTP server and path because I had problems connecting to that server. Even with the guidelines by the OP, I could trigger the bug only occasionally. I converted the script to be executable with manual intervention (see attachment). Still, sometimes both files are also successfully downloaded in the second iteration (i. e. the outer iteration which downloads both files). These results are from a test with Python 2.6.6.

[issue8890] Use tempfile instead of /tmp in examples
engelbert gruber grub...@users.sourceforge.net added the comment:
Assumption:
/tmp is used in examples so the examples work
because /tmp is always writeable
module tempfile is for creating temporary files, the name of which is
unimported, when a user is trying code from documentation it might be hard on
him/her to additionally guess/save the random filenames.
``grep tmp -r CPython3.3/Doc`` (trimmed results and grouped)
* Doc/distutils/install.rst, Doc/install/install.rst:
e.g. ``--install-base=/tmp``
maybe ``--install-base=other-python-base-directory``
if someone installs to another directory, one has a reason and
therefore knows the directory.
* all other e.g. ::
Doc/library/sqlite3.rst::file:`/tmp/example` file::
Doc/library/sqlite3.rst: conn = sqlite3.connect('/tmp/example')
use ``/tmp`` because it is writeable, but assuming the user wants
to program i think it is not so big a burden to assume him/her to
grasp the concept of directories, files and write protection.
So either it can be left out, as in sqlite3.rst, maybe a file
extension would be more helpful, or replaced by a placeholder
like ``my-log-directory`` or ``directory-for-tempfiles``.
I am unsure about the chars ?
list of files:
Doc/distutils/install.rst
Doc/documenting/fromlatex.rst
Doc/howto/logging-cookbook.rst
Doc/install/install.rst
Doc/library/atexit.rst
Doc/library/cgi.rst
Doc/library/imghdr.rst
Doc/library/mailcap.rst
Doc/library/nntplib.rst

Doc/library/packaging.database.rst

I just included one test case, other test case if they should be included (and

Terry J. Reedy tjre...@udel.edu added the comment: I agree with adding '(absolute value)'. I think the following covers the NaN behavior. NaN acts as a positive value that cannot be negated. This should be added to both doc and docstring. I do not think we generally specify the nan behavior for each function, but it usually follows general rules. The copysign(x,nan) behavior is not obvious as nan, like int 0, does not really have a sign.

[issue12414] getsizeof() on code objects is wrong
Martin v. Löwis mar...@v.loewis.de added the comment: For composite objects, getsizeof should only return the memory of the object itself, and not that of other objects it refers to. the object itself definitely includes the struct of the object, and also definitely includes non-PyObject blocks uniquely referred to by the object. It definitely should not return objects it reports in gc.get_referents. It probably should include PyObjects not shared with any other object, and not accessible from outside of the object. There are boundary cases, such as memory blocks which are not PyObject, but may be shared across objects, and PyObjects not reported in get_referents. It seems this case is the latter: the PyObjects are not returned from get_referents, but are certainly available to Python, e.g. through co_code and co_consts. I don't think there sizes should be added to the size of the PyObject, since otherwise accounting algorithms may account for it twice. What's your use case for including it in the total size? -- nosy: +loewis ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12414 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12413] make faulthandler dump traceback of child processes
STINNER Victor victor.stin...@haypocalc.com added the comment: In which case is Python the leader of the group? ... Yes, it's the case by default when you launch a process through a shell. subprocess doesn't use a shell by default, and I don't think that multiprocessing uses a shell to start Python. The subprocess maintains a list of the create subprocesses: subprocess.alive, but you need a reference a reference to this list (or you can access it using the Python namespace, but it requires the GIL and you cannot trust the GIL on a crash). Does multiprocessing maintain a list of child processes? Yes, we don't have any guarantee about the interpreter's state, and furthermore this won't work for processes calling fork() directly. I don't think that we can have a reliable, generic and portable solution for this issue. I suggest to only focus on one use case (debug the multiprocessing and/or subprocess module), and latter try to support more cases. I agree that interpreter state can be inconsistent, but faulthandler does already use read the interpreter state. We cannot do better than best effort. Well, it doesn't really matter if faulthandler crashs, the program is already dying ;-) To simplify the implementation, I propose to patch multiprocessing and/or subprocess to register the pid of the child process in a list in the faulthandler module. It would be better if these modules unregister pid when a subprocess exits, but it's not mandatory. We can send a signal to a non existant process. In the worst case, on a heavy loaded computer, another process may get the same pid, but it's unlikely. I'm quite sure that multiprocessing and subprocess already handle the subprocess exit, so it should be quite simply to add a hook. subprocess can execute any program, not only Python. Send an arbitrary signal to a child process can cause issues. Well, faulthandler is disabled by default, no ? Yes, but I prefer to interfer with unrelated processes if it's possible. By the way, which signal do you want to send to the child processes? Hum, SIGTERM maybe? Don't you register some fatal signals by default? faulthandler.enable() installs a signal handler for SIGSEGV, SIGBUS, SIGILL and SIGABRT signals. (SIGKILL cannot be handled by the application.) A test may replace the signal handler of your signal Well, it's doesn't really matter. If one child process doesn't print the traceback, you have less information, but it is unlikely and we may get the information manually or by changing temporary the signal number. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12413 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

The patch also adds functions _PyOS_SigintEvent and _PyOS_IsMainThread which are implemented in signalmodule.c and declared in intrcheck.c. _PyOS_SigintEvent returns a manual reset event (cast to void*) which is set whenever SIGINT is received. It is Windows only. _PyOS_IsMainThread returns 0 or 1 according to whether the current thread is the main thread. The time and _multiprocessing modules have been updated to use these functions. Note that WaitForMultipleObjects has a bWaitAll parameter.
