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.

Guido van Rossum ee5cf9b672 Bump API version due to the various speedup hacks. 1997-01-18 07:54:03 +00:00
Guido van Rossum 1e6e9a2368 Two speedup hacks. Caching the hash saves recalculation of a string's 
hash value.  Interning strings (which requires hash caching) tries to
ensure that only one string object with a given value exists, so
equality tests are one pointer comparison.  Together, these can speed
the interpreter up by as much as 20%.  Each costs the size of a long
or pointer per string object.  In addition, interned strings live
until the end of times.  If you are concerned about memory footprint,
simply comment the #define out here (and rebuild everything!).

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 04f2b453bb Version 1.1. Fix memory leak and expensive comparison with None. 1997-01-18 02:20:37 +00:00
Guido van Rossum 3e7ae7ab17 Fix the _setmode() patch for MS_WINDOWS: include <fcntl.h> and use 
fileno(std*).

Guido van Rossum 98a9b312e8 Marshal the new stacksize item in code objects. 1997-01-17 21:07:08 +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 3f6e408a31 Add co_stacksize field to codeobject structure, and stacksize argument 
to PyCode_New() argument list.  Also add CO_MAXBLOCKS constant
indicating the maximum static nesting supported by the compiler.
 1997-01-17 20:59:26 +00:00
Guido van Rossum 00f86e6086 Of course, when the type of the argument to dis() is unsupported, it 
should raise TypeError, not ValueError...
 1997-01-17 20:08:18 +00:00
Guido van Rossum bd30795192 More user friedly interface: 
dis() still disassembles the last frame of the lats stack trace.

dis(x) disassembles x, which may be a code object, function, or method.

disassemble(co, [lasti]) disassembles a code object; the lasti
argument is now optional.

disco(...) is an alias for disassemble(...), for backward compatibility.

Roger E. Masse c905fffa15 Added Sjoerd's submitted 'ratecv' method. Made corrections for new names. 
Reindented.
 1997-01-17 18:12:04 +00:00
Guido van Rossum 1d1394e660 Make as sure as we can that the forked child does not return and 
continue the tests.
 1997-01-17 16:13:15 +00:00
Roger E. Masse ed648a25bd Renamed, but not tested. Guido will you try your test script on this? 1997-01-17 16:08:55 +00:00
Roger E. Masse e474fb36ab Renamed. 1997-01-17 16:00:02 +00:00

Roger E. Masse 69ed964f86 Lame test script for the SGI cl C module. 1997-01-17 15:58:35 +00:00
Barry Warsaw e886ea916e (puremodule.c): New module which exports the Purify and Quantify C API 
to Python.  Minimal documentation is included in comments at the top
of the file, and in the Misc/PURIFY.README file.  Note that this
module must be statically linked since Pure doesn't provide shared
stubs libraries.

(Setup.in): Added commented template for pure module

(syslogmodule.c): ins() function wasn't declared static.
 1997-01-17 00:01:33 +00:00
Barry Warsaw bb779ec4d9 README file for hints on Purify'ing or Quantify'ing the Python 
interpreter.  It also mentions the soon to be checked in pure module.

- add opcodes BINARY_LSHIFT ... BINARY_OR

- remove RESERVE_FAST

- Skip M's suggestion for displaying which comparison operator is meant

Roger E. Masse 5f4ce18898 Renamed. 1997-01-16 17:10:22 +00:00
Roger E. Masse 469848a1ea As per GvR recomendations, remove the restriction that binhex only run on 
big-endian machines.  This is done by directing the struct module's pack
and unpack methods to treat the data always in bin endian format.
This has been tested on irix (big endian) and solaris x86 (little endian)
but not yet on the mac.
 1997-01-16 16:51:57 +00:00
Barry Warsaw 47d3500787 set_key(): Use Py_CHARMASK macro to get the character from the array 
unsigned.  This fixes the 8bit-char-in-key platform incompatibility.

I also removed the old backwards compatibility code, and the commented
lisp rotor code.  I retained the lisp docstrings as comments preceding
each function.

Barry Warsaw e4d7821ea4 test is no longer needed 1997-01-16 00:13:11 +00:00
Roger E. Masse 52a6ea7b7d Opps. Added tests for the last two methods that were missing from 
the test program: 'grey2rgb' and 'rgb2grey'
 1997-01-15 20:58:55 +00:00
Roger E. Masse e17ec8d149 Modified to use 'rgbimg' instead of the SGI specific 'imgfile' for reading 
the imagefiles and converting tham to a format suitable for imageop.  Also
added two more tests 'rgb2rgb8' and 'rgb82rgb' which remove the dependence
on the file 'greytest.rgb'.

Note: test_imgfile.py still uses 'greytest.rgb'

Guido van Rossum 1ce7c6fde8 Irix 6 specific files -- thanks Sjoerd! 1997-01-15 19:19:19 +00:00
Jack Jansen 6ad8d13fe2 "ported" Guido's embedding demo to the mac, and wrote some minimal 
notes on embedding on the mac.
 1997-01-15 16:53:37 +00:00
Jack Jansen 52ac037249 Added PyMac_Initialize() routine, to be used by embedding programs (in 
stead of standard Py_Initialize(), which it calls).
