Fri, 15 Nov 2013 17:35:31 +0100

(Merge 3.3) sysmodule.c: fix sys_update_path(), use Py_ARRAY_LENGTH() to get
the size of the fullpath buffer, not PATH_MAX. fullpath is declared using
MAXPATHLEN or MAX_PATH depending on the OS, and PATH_MAX is not declared on
IRIX.

Thu, 07 Nov 2013 23:07:29 +0100

Issue #19512, #19515: remove shared identifiers, move identifiers where they
are used.

Move also _Py_IDENTIFIER() defintions to the top in modified files to remove
identifiers duplicated in the same file.

Wed, 06 Nov 2013 18:27:13 +0100

Issue #19512: sys_displayhook() now uses an identifier for "builtins"
dictionary key and only decodes "\n" string once to write a newline.

So "builtins" and "\n" are only decoded once from UTF-8, at the first call.

Issue #16400: Add command line option for isolated mode.

Sat, 10 Aug 2013 16:36:18 +0200

Issue #16400: Add command line option for isolated mode.

-I

Run Python in isolated mode. This also implies -E and -s. In isolated mode
sys.path contains neither the script’s directory nor the user’s
site-packages directory. All PYTHON* environment variables are ignored,
too. Further restrictions may be imposed to prevent the user from
injecting malicious code.
