Guido van Rossum ca756f2a1d Forget keeping track of whether a dictionary contains all interned 
string keys.  Just doing a pointer compare before the string compare
(in fact before the hash compare!) is just as fast.

Guido van Rossum 44be35aca4 A number of new symbols have appeared (courtesy autoconf 2.12?) 1997-01-22 20:53:30 +00:00
Guido van Rossum 54d93d446b Add --with-dec-threads, for DEL Alpha, which requires -threads as the 
*final* linker argument.  This implies --with-thread.

Reimplemented --with-threads as an alias for --with-thread.

Guido van Rossum b7cf5bb1c2 Darn. Updated version number for configure.in. 1997-01-21 22:03:53 +00:00
Guido van Rossum f78abae10f Let --with-threads be an alias for --with-thread. 1997-01-21 22:02:36 +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 a04d47b319 Don't use static buffers internally for formatstring(). 1997-01-21 16:12:09 +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 fcdd0e40a4 Arrange for PyErr_CheckSignals() to be called via Py_AddPendingCall(). 
This avoids having to call sigcheck() (the same routine by its old
name :-) in the ticker code in ceval.c's main interpreter loop.
 1997-01-21 06:13:09 +00:00
Guido van Rossum ad74fa6674 In the Unix version, arrange for sigcheck() to be called via 
Py_AddPendingCall().  This avoids having to call sigcheck() in the
ticker code in ceval.c's main interpreter loop.
 1997-01-21 06:00:33 +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 3bb63a8dbe Bugfix: remove ref to fast before it's defined. 1997-01-20 04:29:16 +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 f3e85a0356 Changes that appear to give another 12% speedup. 
Rather than allocating a list object for the fast locals and another
(extensible one) for the value stack and allocating the block stack
dynamically, allocate the block stack with a fixed size (CO_MAXBLOCKS
from compile.h), and stick the locals and value stack at the end of
the object (this is now possible since the stack size is known
beforehand).  Get rid of the owner field and the nvalues argument --
it is available in the code object, like nlocals.

This requires small changes in ceval.c only.
 1997-01-20 04:20:52 +00:00
Guido van Rossum cdf578ebaf New lay-out of frame object, for fewer mallocs. 
See frameobject.c checkin message.

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.

Guido van Rossum 2a61e7428d String interning. 1997-01-18 07:55:05 +00:00
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!).
 1997-01-18 07:53:23 +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 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 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 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...
