45b83915f8 New form of PyFPE_END_PROTECT macro. 1997-03-14 04:32:50 +00:00
Guido van Rossum
6af0c00ab6 Fix dumb bug calling parsestrplus with wrong node as argument. 
Add prototypes for parsestr() and parsestrplus() (unrelated, but
seemed to make sense.)

1c6a459921 Define __debug__ as 0 if -O is given, 1 otherwise. Also test for 
errors in initializing the dictionary.
 1997-03-11 18:43:26 +00:00
Guido van Rossum
7c53111d5b Added support for ``if __debug__:'' -- if -O is given, this form is 
recognized by the code generator and code generation for the test and
the subsequent suite is suppressed.

One must write *exactly* ``if __debug__:'' or ``elif __debug__:'' --
no parentheses or operators must be present, or the optimization is
not carried through.  Whitespace doesn't matter.  Other uses of
__debug__ will find __debug__ defined as 0 or 1 in the __builtin__
module.

2dc466169e Oops, remove an unused variable from PyErr_Format(). 1997-02-14 20:57:31 +00:00
Guido van Rossum
7433b12a5c Added new global flag variable Py_InteractiveFlag and new function 
Py_FdIsInteractive().  The flag is supposed to be set by the -i
command line option.  The function is supposed to be called instead of
isatty().  This is used for Lee Busby's wish #1, to have an option
that pretends stdin is interactive even when it really isn't.
 1997-02-14 19:45:36 +00:00

0d85be19e2 *Don't* kill all local variables on function exit. This will be done 
by the frameobject dealloc when it is time for the locals to go.  When
there's still a traceback object referencing this stack frame, we
don't want the local variables to disappear yet.

(Hmm...  Shouldn't they be copied to the f_locals dictionary?)

e8811f85ed Added intern() function. 1997-02-14 15:48:05 +00:00
Guido van Rossum
deb0c5e66c Two small changes: 
- Use co->... instead of f->f_code->...; save an extra lookup of what
we already have in a local variable).

- Remove test for nlocals > 0 before setting fastlocals to
f->f_localsplus; 0 is a rare case and the assignment is safe even
then.

d0eb429b88 Plug a leak with calling something other than a function or method is 
called with keyword arguments -- the keyword and value were leaked.
This affected for instance with a __call__() method.

950361c6ca Patches for (two forms of) optional dynamic execution profiling -- 
i.e., counting opcode frequencies, or (with DXPAIRS defined) opcode
pair frequencies.  Define DYNAMIC_EXECUTION_PROFILE on the command
line (for this file and for sysmodule.c) to enable.

8c5df06ec7 Change the control flow for error handling in the function prelude to 
jump to the "Kill locals" section at the end.  Add #ifdef macintosh
bandaid to make sure we call sigcheck() on the Mac.
 1997-01-24 04:19:24 +00:00

d031c89891 Marshal the line number table of code objects. 1997-01-24 03:44:17 +00:00
Guido van Rossum
da4eb5c3b5 Instead of emitting SET_LINENO instructions, generate a line number 
table which is incorporated in the code object.  This way, the runtime
overhead to keep track of line numbers is only incurred when an
exception has to be reported.

a4240132ec Kill all local variables on function return. This closes a gigantic 
leak of memory and file descriptors (thanks for Roj for reporting
that!).  Alas, the speed goes down by 5%. :-(

70d44787a3 Only call sigcheck() at the ticker code if we don't have true signals. 
This is safe now that both intrcheck() and signalmodule.c schedule a
sigcheck() call via Py_AddPendingCall().

This gives another 7% speedup (never run such a test twice ;-).

7b89b6a660 Intern all names and varnames in newcodeobject(), plus those string 
literals that look like identifiers.  Also intern all strings used as
names during the compilation.

62f7d15d0b Use the stack size from the code object and the CO_MAXBLOCKS constant 
from compile.h.  Remove all eval stack overflow checks.
 1997-01-17 21:05:28 +00:00
Guido van Rossum
8b993a98db Add co_stacksize field to codeobject structure, and stacksize argument 
to PyCode_New() argument list.  Move MAXBLOCKS constant to conpile.h.

Added accurate calculation of the actual stack size needed by the
generated code.

Also commented out all fprintf statements (except for a new one to
diagnose stack underflow, and one in #ifdef'ed out code), and added
some new TO DO suggestions (now that the stacksize is taken of the TO
DO list).

Guido van Rossum
0aa9ee65ab Moved the raise logic out of the main interpreter loop to a separate function. 
The raise logic has one additional feature: if you raise <class>,
<value> where <value> is not an instance, it will construct an
instance using <value> as argument.  If <value> is None, <class> is
instantiated without arguments.  If <value> is a tuple, it is used as
the argument list.

This feature is intended to make it easier to upgrade code from using
string exceptions to using class exceptions; without this feature,
you'd have to change every raise statement from ``raise X'' to ``raise
X()'' and from ``raise X, y'' to ``raise X(y)''.  The latter is still
the recommended form (because it has no ambiguities about the number
of arguments), but this change makes the transition less painful.

b0c168cbe8 Tentative changes to make this work better on 64-bit machines. 
A plain int that doesn't fit in 32 bits will be marshalled using a new
type.  32 bits machines can't handle this and will issue a warning.

e449af7da9 Ellipses -> Ellipsis rename (the dictionary really says that it should 
be Ellipsis!).
Bumped the API version because a linker-visible symbol is affected.
Old C code will still compile -- there's a b/w compat macro.
Similarly, old Python code will still run, builtin exports both
Ellipses and Ellipsis.
