as long as the filename also doesn't end in a suffix that indicates
a binary file (according to the flags in imp.get_suffixes()).
Shrink try...except clauses and replace some of them with explicit checks.
Made sure that the warnings issued by symtable_check_unoptimized()
(about import * and exec) contain the proper filename and line number,
and are transformed into SyntaxError exceptions with -Werror.
(Also remove warning about module-level global decl, because we can't
distinguish from code passed to exec.)
Define PyCompilerFlags type contains a single element,
cf_nested_scopes, that is true if a nested scopes future statement has
been entered at the interactive prompt.
New API functions:
PyNode_CompileFlags()
PyRun_InteractiveOneFlags()
-- same as their non Flags counterparts except that the take an
optional PyCompilerFlags pointer
compile.c: In jcompile() use PyCompilerFlags argument. If
cf_nested_scopes is true, compile code with nested scopes. If it
is false, but the code has a valid future nested scopes statement,
set it to true.
pythonrun.c: Create a new PyCompilerFlags object in
PyRun_InteractiveLoop() and thread it through to
PyRun_InteractiveOneFlags().
defined and export both names.
Solaris also does not define CBAUDEX; it is not clear that CBAUDEXT
(which is defined there) is the same thing, so we only protect against
the lack of CBAUDEX.

Suppress the "Contents" page for HTML; it is not needed for small documents
in the online environment since LaTeX2HTML generates lots of tables of links
anyway.

- In _portable_ftell(), try fgetpos() before ftello() and ftell64().
I ran into a situation on a 64-bit capable Linux where the C
library's ftello() and ftell64() returned negative numbers despite
fpos_t and off_t both being 64-bit types; fgetpos() did the right
thing.
- Define a new typedef, Py_off_t, which is either fpos_t or off_t,
depending on which one is 64 bits. This removes the need for a lot
of #ifdefs later on. (XXX Should this be moved to pyport.h? That
file currently seems oblivious to large fille support, so for now
I'll leave it here where it's needed.)
Add checks for .pyo and .pyd.
Collapse docfunction, docmethod, docbuiltin into the one method docroutine.
Small formatting fixes.
Link the segments of a package path in the title.
Link to the source file only if it exists.
Allow modules (e.g. repr.py) to take precedence over built-ins (e.g. repr()).
Add interruptible synopsis scanner (so we can do searches in the background).
Make HTTP server quit.
Add small GUI for controlling the server and launching searches (like -k).
(Tested on Win2k, Win98, and Linux.)
the more recent versions of that platform, so we use the value (time_t)(-1)
as the error value. This is the type used in the OpenVMS documentation:
http://www.openvms.compaq.com/commercial/c/5763p048.htm#inde
This closes SF tracker bug #404240.
Also clean up an exception message when detecting overflow of time_t values
beyond 4 bytes.
from __future__ import nested_scopes
x=7
def f():
x=1
def g():
global x
def i():
def h():
return x
return h()
return i()
return g()
print f()
print x
This kind of code didn't work correctly because x was treated as free
in i, leading to an attempt to load x in g to make a closure for i.
Solution is to make global decl apply to nested scopes unless their is
an assignment. Thus, x in h is global.
