[issue15057] Potential Bugs in mpd_qdivint and mpd_qrem
New submission from Ken Cheung : I observed a code clone from the following files. function : mpd_qdivint @ (file: "Python-3.3.0a2/Modules/_decimal/libmpdec/mpdecimal.c", line: 3727)~3763 function : mpd_qrem @ (file: "Python-3.3.0a2/Modules/_decimal/libmpdec/mpdecimal.c", line: 6331)~6361 The function mpd_qdivint checks the condition "mpd_isinfinite(a) && mpd_isinfinite(b)" while mpd_qrem does not. I wonder if this is necessary in mpd_qrem. The source code is included in the attachment. Hope it helps. -- components: Library (Lib) files: mpdecimal_clone.txt messages: 162717 nosy: Ken.Cheung priority: normal severity: normal status: open title: Potential Bugs in mpd_qdivint and mpd_qrem type: behavior versions: Python 3.3 Added file: http://bugs.python.org/file25949/mpdecimal_clone.txt ___ Python tracker <http://bugs.python.org/issue15057> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15058] Potential Bugs in dlpvalloc and dlvalloc
New submission from Ken Cheung : I observed a code clone from the following files. function : dlpvalloc @ (file: "Python-3.3.0a2/Modules/_ctypes/libffi/src/dlmalloc.c", line: 4360)~4362 function : dlvalloc @ (file: "Python-3.3.0a2/Modules/_ctypes/libffi/src/dlmalloc.c", line: 4353)~4355 The function dlpvalloc performs a bitwise operation at return while dlvalloc does not.

[issue15059] Potential Bug in mpd_qresize and mpd_qresize_zero
New submission from Ken Cheung : I observed a code clone from the following files. function : mpd_qresize @ (file: "Python-3.3.0a2/Modules/_decimal/libmpdec/mpdecimal.c", line: 481)~493 function : mpd_qresize_zero @ (file: "Python-3.3.0a2/Modules/_decimal/libmpdec/mpdecimal.c", line: 501)~517 The two functions perform different in the else if condition. I wonder this is due to functionality requirement or a bug. The source code is included in the attachment.

[issue15107] Potential Bug in mpdecimal.c
New submission from Ken Cheung : I observed a code clone from the following files. function : mpd_qexp @ (file: "Python-3.3.0a4/Modules/_decimal/libmpdec/mpdecimal.c", line: 4092)~4165 function : mpd_qln @ (file: "Python-3.3.0a4/Modules/_decimal/libmpdec/mpdecimal.c", line: 4525)~4612 In the first few lines of this clone, the function mpd_qexp only calls mpd_setspecial when mpd_isnegative is false while the function mpd_qln calls mpd_setspecial independent of the value of mpd_isnegative. I wonder the checking is necessary in the function mpd_qln. The source code is included in the attachment.
