Guido van Rossum 644a12b00c Tweaks to keep the Microsoft compiler quier. 1997-04-09 19:24:53 +00:00
Guido van Rossum 5f5e817e00 Support for alternative string quotes (a"xx", b"xx", c"xx", ...).
In interactive mode, do generate code for single-string statements.
1997-04-06 03:41:40 +00:00
Guido van Rossum 2a7f58de1c Allow passing a .pyo file.
Print correct name in fatal error from PyErr_Print.
1997-04-02 05:28:38 +00:00
Guido van Rossum 228d7f3f67 Added assert statement. 1997-04-02 05:24:36 +00:00
Guido van Rossum 8ecd1ad785 Added assert grammar. 1997-04-02 05:24:08 +00:00
Guido van Rossum c6472e9ee1 1. Add string conversions to int(), long(), float(). (Not to complex()!)
2. Fix two bugs in complex():

   - Memory leak when using complex(classinstance) -- r was never
   DECREF'ed.

   - Conversion of the second argument, if not complex, was done using
   the type vector of the 1st.

Guido van Rossum 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.)
1997-03-11 21:25:55 +00:00
Guido van Rossum 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.
1997-03-11 18:42:21 +00:00
Guido van Rossum 0824f63cfc When -O is given, use ".pyo" instead of ".pyc". 1997-03-11 18:37:35 +00:00
Guido van Rossum c43b685054 Clarify error message for unexpected keyword parameter. 1997-03-10 22:58:23 +00:00
Guido van Rossum 82598051e6 Greatly renamed. Not a very thorough job -- I'm going to restructure
it anyway.
1997-03-05 00:20:32 +00:00
Guido van Rossum 8e793d925c Add global Py_OptimizeFlag. SET_LINENO is omitted again unless this is
nonzero.
1997-03-03 19:13:14 +00:00
Guido van Rossum 0ae748d3c4 Changes for Lee Busby's SIGFPE patch set.
New file pyfpe.c and exception FloatingPointError.
Surround some f.p. operations with PyFPE macro brackets.
1997-02-14 22:58:07 +00:00
Guido van Rossum 0f4bbd2f34 Keep gcc -Wall happy. 1997-02-14 21:12:56 +00:00
Guido van Rossum 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
Guido van Rossum 1548bacb14 Added convenience function PyErr_Format(exception, formatstring, ...) -> NULL. 1997-02-14 17:09:47 +00:00
Guido van Rossum 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?)
1997-02-14 16:32:14 +00:00
Guido van Rossum 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.

Guido van Rossum 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.

Bug reported and fix supplied by Jim Fulton.
1997-01-27 21:30:09 +00:00
Guido van Rossum 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.
1997-01-24 13:49:28 +00:00
Guido van Rossum 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
Guido van Rossum 43f1b8d6e4 Added optional interface for dynamic execution profile (to be gathered
in ceval.c).
1997-01-24 04:07:45 +00:00
Guido van Rossum b3f515af64 Get the line number from PyCode_Addr2Line instead of believing
tb_lineno.  Store it in tb_lineno for the user.
1997-01-24 04:02:55 +00:00
Guido van Rossum 99d182550b New magin number (because of linenumber table). 1997-01-24 03:44:53 +00:00
Guido van Rossum 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.
1997-01-24 03:43:35 +00:00
Guido van Rossum 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%. :-(
1997-01-21 21:18:36 +00:00
Guido van Rossum 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 ;-).
1997-01-21 06:15:24 +00:00
Guido van Rossum 1aa14838d2 Cleanup:
- fix bug in Py_MakePendingCalls() with threading
- fix return type of do_raise
- remove build_slice (same as PySlice_New)
- remove code inside #if 0
- remove code inside #ifdef CHECK_STACK
- remove code inside #ifdef SUPPORT_OBSOLETE_ACCESS
- comment about newimp.py should refer to ni.py

Guido van Rossum 554fa49500 get build info from elsewhere 1997-01-20 18:34:55 +00:00
Guido van Rossum 768360243a Changes for frame object speedup:
- get fastlocals differently
- call newframeobject() with fewer arguments
- toss getowner(), which was unused anyway
1997-01-20 04:26:20 +00:00
Guido van Rossum 7eb883a18e Remove unused variable. 1997-01-18 20:04:05 +00:00
Guido van Rossum 8d75161671 Intern the string "__complex__". 1997-01-18 08:04:16 +00:00
Guido van Rossum 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.
1997-01-18 08:02:57 +00:00
Guido van Rossum 3dfd53b4c8 Add "if (x != NULL) continue;" (or similar for err==0) before the
break to most cases, as suggested by Tim Peters.  This gives another
8-10% speedup.
1997-01-18 02:46:13 +00:00
Guido van Rossum 98a9b312e8 Marshal the new stacksize item in code objects. 1997-01-17 21:07:08 +00:00
Guido van Rossum 7af8130857 Working semaphore implementation by Sjoerd. 1997-01-17 21:06:41 +00:00
Guido van Rossum dd5db43905 New MAGIC number (code objects have one more item when marshalled). 1997-01-17 21:06:11 +00:00
Guido van Rossum 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).
1997-01-17 21:04:03 +00:00
Guido van Rossum 635abd24f0 Check for duplicate keyword arguments at compile time. 1997-01-06 22:56:52 +00:00
Guido van Rossum 8f49e12a0e Make builtin_module_names a tuple instead of a list. 1997-01-06 22:55:54 +00:00
Guido van Rossum 408027ea46 Rename DEBUG macro to Py_DEBUG 1996-12-30 16:17:54 +00:00
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.

Guido van Rossum c1547d930f Better way to handle 64-bit ints, keeping gcc -Wall happy.
Tested with AMK's help.
1996-12-10 15:39:04 +00:00
Guido van Rossum 1a2c5cbcc4 Add unistd.h to make gcc -Wall happy. 1996-12-10 15:37:36 +00:00
