New submission from Elwyn Davies: Enhancement requested for module mmap: Alter the interface of mmap.read from mmap.read(num) to mmap.read([num]) reading the whole file if no argument provided.
The read function in the mmap module (Modules/mmapmodule.c) *requires* an argument whereas for the standard file read function the argument is optional and the function reads the remainder of the file if absent. The mmap module knows how big the file is, so it should be no problem to internally use the remaining length if no argument is supplied. This would avoid having to write (for example) f = mmap.mmap(file_desc, file_size) b = f.read(file_size) j = json.loads(b) instead of f = mmap.mmap(file_desc, file_size) j = json.load(f) ---------- components: Library (Lib) messages: 174123 nosy: elwynd priority: normal severity: normal status: open title: Enhancement for mmap_read: Consistency with standard file read type: enhancement versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16358> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
