Guido van Rossum b05a5c7698 Instead of importing graminit.h whenever one of the three grammar 'root' 
symbols is needed, define these in Python.h with a Py_ prefix.
 1997-05-07 17:46:13 +00:00
Guido van Rossum 666b17a280 New dir() function -- 
- uses abstract interface where possible
- uses __members__ and __methods__
- returns [] when an object has no info available
 1997-05-06 16:36:57 +00:00
Guido van Rossum 478e718aca Keep MS compiler happy: use (int)strlen() when comparing; make sure 
not to use kill().
 1997-05-06 15:24:59 +00:00
Guido van Rossum fc49073cd0 Used operators from abstract.h where possible (arithmetic operators, 
get/set/del item).  This removes a pile of duplication.  There's no
abstract operator for 'not' but I removed the function call for it
anyway -- it's a little faster in-line.
 1997-05-06 15:06:49 +00:00
Guido van Rossum fdf95dd525 Checkin of Jack's buffer mods. 
Not really checked, but didn't fail any tests either...
 1997-05-05 22:15:02 +00:00
Guido van Rossum 13454c3f9c Fix old typo PyArgs_VaParse -> PyArg_VaParse. 
(Redoing the checking without merging in Jack's buffer mods.)
 1997-05-05 21:57:29 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management. 
All per-thread globals are moved into a struct which is manipulated
separately.
 1997-05-05 20:56:21 +00:00
Guido van Rossum 73237c54b4 Only use PyCode_Addr2Line to get tb_lineno when Py_OptimizeFlag is set. 1997-05-05 20:53:25 +00:00
Guido van Rossum 9218b70bdc Remove 2 out of 3 __FreeBSD__ tests. 
These are no longer needed as of FreeBSD 2.0.5, according to
Thomas Gellekum <tg@ihf.rwth-aachen.de>.
 1997-05-05 15:03:26 +00:00
Guido van Rossum f4806c2a85 Add detach call so threads are GC'ed. 1997-04-30 19:59:22 +00:00
Guido van Rossum bc2472db8e Avoid some potential (though unlikely) sprintf buffer overflows. 1997-04-30 19:07:54 +00:00
Guido van Rossum 15e33a4c42 Avoid sprintf buffer overflow if more than 9999 arguments. 1997-04-30 19:00:27 +00:00
Guido van Rossum d11bfdd9f5 Ugly hack for SGI IRIX 6.2. Apparently _POSIX_THREADS is defined even 
when the pthread package is not installed.  configure knows better, so
#undef _POSIX_THREADS when pthread.h does not exist.
 1997-04-29 21:48:34 +00:00
Guido van Rossum bb5c6f8529 Oops, forgot one: inittab. 1997-04-29 20:42:30 +00:00
Guido van Rossum 0bac33b420 Oops, forgot one: inittab. 1997-04-29 20:24:10 +00:00
Guido van Rossum 79f25d9a7b Quickly renamed the remaining files -- this directory is done. 1997-04-29 20:08:16 +00:00
Guido van Rossum 65bf9f265e Quickly renamed. 1997-04-29 18:33:38 +00:00
Guido van Rossum 373c869a6a Quickly renamed. Also removed the long comment explaining why this is 
better than the old error API.
 1997-04-29 18:22:47 +00:00
Guido van Rossum b209a116cf Quickly renamed. 1997-04-29 18:18:01 +00:00
Guido van Rossum 62cb0bafe2 Moved to ../Modules. 1997-04-29 15:50:32 +00:00
Guido van Rossum 58a6ac55d2 Removed cgensupport.[co] (to ../Modules). 1997-04-29 15:42:53 +00:00
Guido van Rossum c474deaaf6 Expand one level of symbolic link in sys.argv[0] before inserting its 
dirname in sys.path.  This means that you can create a symbolic link
foo in /usr/local/bin pointing to /usr/yourname/src/foo/foo.py, and
then invoking foo will insert /usr/yourname/src/foo in sys.path, not
/usr/local/bin.  This makes it easier to have multifile programs
(before, the program would have to do an os.readlink(sys.argv[0])
itself and insert the resulting directory in sys.path -- Grail does
this).

Note that the expansion is only used for sys.path; sys.argv[0] is
still the original, unadorned filename (/usr/local/bin/foo in the
example).
 1997-04-25 15:38:31 +00:00
Guido van Rossum 03a7466b8f OK, ready to make 'assert' a keyword (instead of '__assert__'). 1997-04-16 00:34:46 +00:00
Guido van Rossum 7844e38a98 Keep Microsoft VC happy. 1997-04-11 20:44:04 +00:00
Guido van Rossum 6bf62dad9e Keep gcc -Wall and Microsoft VC happy. 1997-04-11 20:37:35 +00:00
Guido van Rossum 1d2e240954 (Jack:) On the Mac, don't automatically enable dynamic loading. 1997-04-11 19:22:06 +00:00
Guido van Rossum 62bf108392 (Jack:) Don't define TRUE and FALSE if already defined. 1997-04-11 19:19:46 +00:00
Guido van Rossum 6976a52099 (Jack:) On the Mac, use standard strerror() if using MSL C-library. 1997-04-11 19:18:23 +00:00
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.
 1997-03-31 17:15:43 +00:00
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.
 1997-01-27 23:42:36 +00:00
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
 1997-01-21 05:34:20 +00:00
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.
 1996-12-10 18:07:35 +00:00
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
Guido van Rossum 067998f35e Add const to error and newstring functions 1996-12-10 15:33:34 +00:00
Guido van Rossum 80bb9655f0 Keep gcc -Wall happy. 1996-12-05 23:27:02 +00:00
Guido van Rossum ed0af8fe70 Support __complex__ method on instances, for complex() conversion. 
Keep gcc -Wall happy.
 1996-12-05 23:18:18 +00:00
Guido van Rossum 150b2df682 Change the Don Beaudry hack into the Don B + Jim F hack; now, if *any* 
base class is special it gets invoked.

Make gcc -Wall happy.
 1996-12-05 23:17:11 +00:00
Guido van Rossum 3afb5959aa Some extra flags that an HPUX user wants me to add. 1996-12-05 23:15:35 +00:00
Guido van Rossum 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.
 1996-12-05 23:15:02 +00:00
Guido van Rossum d266eb460e New permission notice, includes CNRI. 1996-10-25 14:44:06 +00:00
Guido van Rossum b75fba04c7 Forget about Ellipses b/w compatibility. 1996-10-16 04:18:36 +00:00
Guido van Rossum 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.
 1996-10-11 16:25:41 +00:00
Guido van Rossum cf1474b73a Sjoerd's thread changes (including down_sema typo fix). 
Note: waitflag not supported on NT.
 1996-10-08 14:17:53 +00:00
Guido van Rossum 452a9833c9 Added line number to most compile-time error messages. 1996-09-17 14:32:04 +00:00
Guido van Rossum 9b38a145e2 Rationalized MS ifdefs 1996-09-11 23:12:24 +00:00
Guido van Rossum cc88341e6d Changes to setpythonpath(): 
Test for / as well as for SEP for MS filenames.
Drop trailing separator from sys.path[0] for MS and Unix filenames.
 1996-09-10 14:44:21 +00:00
Guido van Rossum b072150d7f Stupid bug: complex(x,y) would yield x+xj 1996-09-07 15:55:27 +00:00
Guido van Rossum 57b1822459 *** empty log message *** 1996-08-29 18:10:41 +00:00
Guido van Rossum 927f6e68fb Needed more includes... 1996-08-29 18:10:30 +00:00
Guido van Rossum bae29713ec *** empty log message *** 1996-08-29 17:48:26 +00:00
Guido van Rossum 6eea32622c typo (#indef -> #undef) 1996-08-26 14:58:54 +00:00
Guido van Rossum d8a6d1c2e7 Afterthough: leave both leading underscores in, 
so __spam becomes _ClassName__spam.
 1996-08-24 07:54:27 +00:00
Guido van Rossum fe2236f3c8 Oops need to mangle global statement separately 1996-08-24 07:29:04 +00:00
Guido van Rossum 8ff077b094 Name mangling, what the heck! 1996-08-24 06:21:31 +00:00
Guido van Rossum 8b9ea873ad Use MS_DLL_ID as sys.winver 1996-08-23 18:14:47 +00:00
