[issue19358] Integrate Argument Clinic into CPython build

New submission from Gareth Rees: The help text for the len() built-in function says: Return the number of items of a sequence or mapping. This omits to mention that len() works on sets too.

Similarly, the documentation for len() says: The argument may be a sequence (string, tuple or list) or a mapping (dictionary). I suggest this be changed to The argument may be a sequence (string, tuple or list), a mapping (dictionary), or a set. (Of course, strictly speaking, len() accepts any object with a __len__ method, but sequences, mappings and sets are the ones that are built-in to the Python core, and so these are the ones it is important to mention in the help and the documentation.) -- assignee: docs@python components: Documentation files: len-set.patch keywords: patch messages: 201019 nosy: Gareth.Rees, docs@python priority: normal severity: normal status: open title: Documentation for len() fails to mention that it works on sets type: enhancement Added file: http://bugs.python.org/file32313/len-set.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19362 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

After all, there are other built in types it works on as well: bytearray, frozenset, memoryview. For the other, the number of items in a sequence or container type would mostly cover it, but at the cost of being a bit obscure. Perhaps that's OK for the help text, though, since it is supposed to be a reminder, not the full documentation. Another even more obscure alternative would be the number of items in a Sized object, which would also be more accurate (since an object with a __len__ doesn't *have* to conform fully to the sequence or container ABCs...nor does a container *have* to implement __len__). -- nosy: +r.david.murray ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19362 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19332] Guard against changing dict during iteration
Serhiy Storchaka added the comment: In the first patch the counter was placed in the _dictkeysobject structure. In the second place it is placed in the PyDictObject so it now has no memory cost. Access time to new counter for non-modifying operations is same as in current code. The only additional cost is time cost for modifying operations. But modifying operations is usually much rare than non-modifying operations, and the incrementing one field takes only small part of the time needed for all operation. I don't think this will affect total performance of real programs. -- Added file: http://bugs.python.org/file32319/dict_mutating_iteration_2.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19332 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Henry Corrigan-Gibbs: Since upgrading to Mac OS X 10.9 (13A603), the interactive python interpreter crashes after I enter two lines of code, no matter how simple they are. The trace below shows that the shell segfaults after entering the integer 1 followed by the integer 1 (on separate lines). The computer is a Macbook Pro, but I was able to reproduce the bug on a Macbook Air as well. # ### Trace of session ### $ python Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type help, copyright, credits or license for more information. 1 1 1 Segmentation fault: 11 # ### Apple crash report data ### Process: Python [1664] Path: /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python Identifier: Python Version: 2.7.2 (2.7.2) Code Type: X86-64 (Native) Parent Process: bash [1661] Responsible: Terminal [1658] User ID: 501 Date/Time: 2013-10-23 14:38:46.854 -0700 OS Version: Mac OS X 10.9 (13A603) Report Version: 11 Anonymous UUID: 7AFE5583-559F-1AF6-8F53-1AB95063B98E Sleep/Wake UUID: 0112A8E8-BB6F-4797-A38D-DA6F40F06329 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x VM Regions Near 0: -- __TEXT 0001-00011000 [4K] r-x/rwx SM=COW /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 readline.so 0x0001002edf97 call_readline + 647 1 org.python.python 0x00018ad2 PyOS_Readline + 274 2 org.python.python 0x0001a328 tok_nextc + 104 3 org.python.python 0x0001aad3 PyTokenizer_Get + 147 4 org.python.python 0x000156ca parsetok + 218 5 org.python.python 0x0001000e63b2 PyParser_ASTFromFile + 146 6 org.python.python 0x0001000e7613 PyRun_InteractiveOneFlags + 243 7 org.python.python 0x0001000e78fe PyRun_InteractiveLoopFlags + 78 8 org.python.python 0x0001000e80e1 PyRun_AnyFileExFlags + 161 9 org.python.python 0x0001000fe77c Py_Main + 2940 10 org.python.python 0x00010f14 0x1 + 3860 Thread 0 crashed with X86 Thread State (64-bit): rax: 0x rbx: 0x00010035c140 rcx: 0x000fc080 rdx: 0x00087db0 rdi: 0x rsi: 0x0001002ee254 rbp: 0x7fff5fbff660 rsp: 0x7fff5fbff590 r8: 0x00010035e700 r9: 0x00010035e750 r10: 0x3500e0a1 r11: 0x0001 r12: 0x0001 r13: 0x0001 r14: 0x7fff5fbff620 r15: 0x7fff5fbff5a0 rip: 0x0001002edf97 rfl: 0x00010202 cr2: 0x Logical CPU: 1 Error Code: 0x0004 Trap Number: 14 Binary Images: 0x1 -0x10fff +org.python.python (2.7.2 - 2.7.2) 639E72E4-F205-C034-8E34-E59DE9C46369 /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python 0x13000 -0x10016cfef +org.python.python (2.7.2, [c] 2004-2011 Python Software Foundation. - 2.7.2) 49D18B1A-C92D-E32E-A7C1-086D0B14BD76 /Library/Frameworks/Python.framework/Versions/2.7/Python 0x1002ec000 -0x1002eefff +readline.so (???) 25AB2CA6-C3CC-9F24-F619-C85D51AD8A38 /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so 0x1004b -0x1004ceffb libedit.2.dylib (39) 1B0596DB-F336-32E7-BB9F-51BF70DB5305 /usr/lib/libedit.2.dylib 0x7fff6cc9f000 - 0x7fff6ccd2817 dyld (239.3) D1DFCF3F-0B0C-332A-BCC0-87A851B570FF /usr/lib/dyld 0x7fff885e1000 - 0x7fff8860aff7 libc++abi.dylib (48) 8C16158F-CBF8-3BD7-BEF4-022704B2A326 /usr/lib/libc++abi.dylib 0x7fff8860b000 - 0x7fff88659fff libcorecrypto.dylib (161.1) F3973C28-14B6-3006-BB2B-00DD7F09ABC7 /usr/lib/system/libcorecrypto.dylib 0x7fff88d06000 - 0x7fff88d17ff7 libz.1.dylib (53) 42E0C8C6-CA38-3CA4-8619-D24ED5DD492E /usr/lib/libz.1.dylib 0x7fff88d6e000 - 0x7fff88d77ff3 libsystem_notify.dylib (121) 52571EC3-6894-37E4-946E-064B021ED44E /usr/lib/system/libsystem_notify.dylib 0x7fff896da000 - 0x7fff896dbff7 libDiagnosticMessagesClient.dylib (100) 4CDB0F7B-C0AF-3424-BC39-495696F0DB1E /usr/lib/libDiagnosticMessagesClient.dylib 0x7fff89a9b000 - 0x7fff89a9eff7 libdyld.dylib (239.3) 62F4D752-4089-31A8-8B73-B95A68893B3C /usr/lib/system/libdyld.dylib 0x7fff8a059000 - 0x7fff8a05dfff libsystem_stats.dylib (93.1.26) B9E26A9E-FBBC-3938-B8B7-6CF7CA8C99AD
[issue19369] PyObject_LengthHint is slow

[issue16113] Add SHA-3 (Keccak) support
haakon added the comment: Please make sure that the currently committed code is not released as part of Python 3.4. SHA-3 is not standardised yet, and NIST has said that they intend to make some changes to the Keccak SHA-3 submission before standardisation as a FIPS. The links englabenny posted have a good overview of the SHA-3 timeline and the proposed changes. It would be very confusing if hashlib in Python 3.4 came with a sha3 that was incompatible with the final standard. -- nosy: +haakon ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16113 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
