[issue24502] OS X 2.7 package has zeros for version numbers in sub-packages
Ned Deily added the comment:
Right, that would be a good reason! I seem to recall that, when I initially
tested flat-package building and installation, there were problems with pkgs
not getting properly installed when version was set, possibly due to confusion
between installs and upgrades. And that might have been due in part to our
abuse of some of the Info.plist keys, in particular, CFBundleVersion, at least
for pre-releases ('3.5.0b2'). I'd like to move away from installer packages
altogether but that will have to wait until 3.6. We may be able to get a
proper version number through pkgutil for current releases but it will require
a fair amount of time to explore and thoroughly test. (Some automated install
tests would make it a lot easier.)

[issue24546] sequence index bug in random.choice
Mark Dickinson added the comment: Agreed with Tim Peters about this not being possible with fully compliant IEEE 754 arithmetic (see http://stackoverflow.com/a/3041071/270986 for a sketch of a proof), but it's certainly a possibility with double rounding, as Steven's result demonstrates. And 32-bit Linux is currently the worst offender for double rounding: IIRC OS X uses the SSE2 instructions exclusively for floating-point arithmetic, and 64-bit Linux tends to do the same. Windows uses the x87 FPU, but sets the FPU precision to 53-bits, so you don't see double rounding within the normal range (though it's still possible with computations having subnormal results). So I'd say that yes, this *is* a bug in random.choice, though it's one that should show up very rarely indeed. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24546 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24564] shutil.copytree fails when copying NFS to NFS
Min RK added the comment: On a bit of further investigation, the NFS files have an xattr `system.nfs4_acl`. This can be read, but attempting to write it fails with EINVAL. Attempting to copy from NFS to non-NFS fails with ENOTSUP, which is caught and ignored, but copying from NFS to NFS raises EINVAL, which raises. Adding `EINVAL` to the ignored errnos would fix the problem, but might hide real failures (I'm not sure about the real failures, but it seems logical). Since the `copy_function` is customizable to switch between `copy` and `copy2`, making copystat optional on files, perhaps the `copystat` should be optional on directories, as well. -- nosy: +minrk ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24564 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24565] the f_lineno getter is broken
New submission from Xavier de Gaye: The last paragraph of Objects/lnotab_notes.txt explains that the f_lineno member of the PyFrameObject structure is needed to store the line number of the last line tracing event so that this value may be used as the line number of the return event instead of the (sometimes confusing) value computed from f_lasti. The f_lineno getter must then return the value of f-f_lineno (instead of the value computed from f-f_lasti) when tracing is set. The current implementation translates tracing is set as the local f_trace trace function is not NULL, this is wrong for the following reasons: * AFAIK it is not documented anywhere that Python users implementing a trace function must delete the local f_trace functions of all the frames when setting the global trace function to None via sys.settrace(None) (issue 7238). * Bdb.set_continue() in the bdb module of the std lib seems to know about this and attempts to do it, but fails to delete f_trace from the topmost frame, named botframe (sic) (issue 16482, issue 17697). * It is not obvious how to delete the f_trace of all suspended generators when setting the global trace function to None (issue 17277). * _PyTraceback_Add() in Python/traceback.c sets frame-f_lineno, obviously forgetting that it is useless since its f_trace is NULL. This patch changes the semantics of f_lineno by stating that f_lineno is invalid when its value is -1. When tracing, the f_lineno of all the frames on the stack is valid. The f_lineno of a suspended generator is always invalid. -- components: Interpreter Core files: f_lineno.patch keywords: patch messages: 246275 nosy: belopolsky, xdegaye priority: normal severity: normal status: open title: the f_lineno getter is broken versions: Python 3.6 Added file: http://bugs.python.org/file39865/f_lineno.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24565 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24564] shutil.copytree fails when copying NFS to NFS
New submission from Jess Hamrick:
shutil.copytree seems to fail when copying files across NFS filesystems. In
this example (see bug_demo.py), /tmp is a normal ext4 filesystem and the
current working directory is NFS (version 4). Interestingly, it works fine to
to copy between ext4 and NFS, just not NFS and NFS (even if it's the same NFS
mount).
Depending on the specific version of 3.4, there are slightly different errors.
For 3.4.0:

shutil.Error: [('demo_files', 'demo_files3', [Errno 22] Invalid argument:

This is probably related to https://bugs.python.org/issue17076 and my guess is
that's also why there is a difference in the error messages between 3.4.0 and
3.4.3.

That is, while random.choice() can suffer double-rounding surprises in _some_ cases, it cannot in the case actually reported here: in the 64-bit extended-precision format, there are at least 64 - (53 + (35).bit_length()) = 5 trailing zeroes in any possible random.random() * 35 result.

Some further information: if I run copystat directly on 3.4.3, I get
essentially the same error as on 3.4.0. So really it only looks like the
difference is just in how the error is reported:

Also, I should mention that I did test this on 2.7 as well, and it is not an
issue there.

[issue24546] sequence index bug in random.choice
Tim Peters added the comment: Raymond, there are (at least) two bugs here: 1. The original bug report. Nobody yet has any plausible theory for what went wrong there. So won't fix wouldn't be appropriate. If the OP can't provide more information, neither a reproducible test case, then after a while closing this report as works for me would be appropriate. 2. The double rounding bug. That cannot be the cause of the OP's problem, so doesn't really belong in this report. Nobody knows how rare it is. I suspect, but have not proved, that 1. - 2.**-53 is the only random.random() result for which it's possible that double-rounding can cause int(i * random.random()) == i. Given that unlikely - but possible - value, there are at least half a million ints 0 i 10 for which equality holds (but only on platforms where the double rounding bug is possible, which doesn't include any platform I use ;-) ). That probably should get a report of its own. It's unintended and unanticipated behavior, causing simple code to raise a wholly unexpected unpredictable exception. That's a bug to me. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24546 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

1.) In SRE(search), pattern[3] is equal to 1073741952 (0x40080). What's
more, the program doesn't limit the max size, which causes the end pointer is
pointed to an invalid and large address( bigger than ptr).
2.) Then program run while (ptr = end) { state-start = state-ptr = ptr++,..}
, but state-end pointer is the orignal value.3.) After a while's running, it
comes to SRE(count) and adjust the end, end - ptr = 0x7fff, which is
largger than 0x40080, ptr has been pointed to an invalid address.
3.) After a while, it runs to function SRE(count) and adjust the end, end - ptr

[issue24567] random.choice IndexError due to double-rounding
New submission from Steven D'Aprano: While investigating issue 24546, I discovered that at least some versions of Python on 32-bit Linux have a double-rounding bug in multiplication which may lead to an unexpected IndexError in random.choice. See http://bugs.python.org/issue24546 for additional discussion, but the short version is that due to double-rounding, if random.random returns (1. - 2.**-53), int(i * random.random()) may return 1 for some i = 2049, and random.choice will then evaluate seq[len(seq)], raising IndexError. -- messages: 246291 nosy: Serge Anuchin, haypo, mark.dickinson, r.david.murray, rhettinger, serhiy.storchaka, skrah, steven.daprano, tim.peters priority: normal severity: normal status: open title: random.choice IndexError due to double-rounding type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5, Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24567 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24553] improve test coverage for subinterpreters
Stefan Krah added the comment: I think for fast access we need a hybrid solution that allows static types (heap types slowed down _decimal) *and* cache the thread local values (like it's currently done for the thread-local context in _decimal). Caching the context brought an enormous speedup (about 20%). I'm not sure if all that can be done in a general API, but it's clearly the fastest way. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24553 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24553] improve test coverage for subinterpreters
Stefan Krah added the comment: Now I'm wondering what further test coverage we really need... Ideally we'd test every C module with the tests executing in parallel (sort of) in multiple interpreters. I have done so for _decimal, which is mostly okay due to the thread-local contexts. However, there are a couple of minor glitches. The reason I haven't pursued this is that *if* you run _decimal in multiple interpreters, you get nasty sounding (but harmless) warnings from libmpdec, which complains about being initialized multiple times. So from the absence of bug reports I concluded that no one is using the sub-interpreter feature with _decimal. -- nosy: +skrah ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24553 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
