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%. :-(

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 ;-).

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

Bugfix: remove ref to fast before it's defined.

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
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.

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!).

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).

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.
