* Two small changes:Guido van Rossum1997-01-271-5/+3
| | | | | | | | | - 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.
* Plug a leak with calling something other than a function or method isGuido van Rossum1997-01-271-4/+3
| | | | | | | 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.
* Patches for (two forms of) optional dynamic execution profiling --Guido van Rossum1997-01-241-0/+68
| | | | | | 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.
* Change the control flow for error handling in the function prelude toGuido van Rossum1997-01-241-23/+17
| | | | | jump to the "Kill locals" section at the end. Add #ifdef macintosh bandaid to make sure we call sigcheck() on the Mac.
* Added optional interface for dynamic execution profile (to be gatheredGuido van Rossum1997-01-241-2/+11

| | | | | | 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.
* Kill all local variables on function return. This closes a giganticGuido van Rossum1997-01-211-0/+12
| | | | | 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.Guido van Rossum1997-01-211-2/+6
| | | | | | | 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:Guido van Rossum1997-01-211-222/+10
| | | | | | | | | | - 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
* get build info from elsewhereGuido van Rossum1997-01-201-9/+2
|
* Changes for frame object speedup:Guido van Rossum1997-01-201-14/+2
| | | | | | - get fastlocals differently - call newframeobject() with fewer arguments - toss getowner(), which was unused anyway
* Remove unused variable.Guido van Rossum1997-01-181-1/+0
|
* Intern the string "__complex__".Guido van Rossum1997-01-181-1/+1
|
* Intern all names and varnames in newcodeobject(), plus those stringGuido van Rossum1997-01-181-7/+22
| | | | | literals that look like identifiers. Also intern all strings used as names during the compilation.
* Add "if (x != NULL) continue;" (or similar for err==0) before theGuido van Rossum1997-01-181-18/+60
| | | | | break to most cases, as suggested by Tim Peters. This gives another 8-10% speedup.
* Marshal the new stacksize item in code objects.Guido van Rossum1997-01-171-1/+3
|
* Working semaphore implementation by Sjoerd.Guido van Rossum1997-01-171-3/+64
|
* New MAGIC number (code objects have one more item when marshalled).Guido van Rossum1997-01-171-1/+2
|
* Use the stack size from the code object and the CO_MAXBLOCKS constantGuido van Rossum1997-01-171-2/+10
| | | | from compile.h. Remove all eval stack overflow checks.
* Add co_stacksize field to codeobject structure, and stacksize argumentGuido van Rossum1997-01-171-62/+253
| | | | | | | | | | | | 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).
* Check for duplicate keyword arguments at compile time.Guido van Rossum1997-01-061-12/+20

* Make builtin_module_names a tuple instead of a list.Guido van Rossum1997-01-061-0/+5
|
* Rename DEBUG macro to Py_DEBUGGuido van Rossum1996-12-303-9/+9
|
* Moved the raise logic out of the main interpreter loop to a separate function.Guido van Rossum1996-12-101-60/+127
| | | | | | | | | | | | | | | 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.
* Better way to handle 64-bit ints, keeping gcc -Wall happy.Guido van Rossum1996-12-101-30/+18
| | | | Tested with AMK's help.
* Add unistd.h to make gcc -Wall happy.Guido van Rossum1996-12-101-0/+4

* Support __complex__ method on instances, for complex() conversion.Guido van Rossum1996-12-051-1/+23
| | | | Keep gcc -Wall happy.
* Change the Don Beaudry hack into the Don B + Jim F hack; now, if *any*Guido van Rossum1996-12-051-28/+26
| | | | | | base class is special it gets invoked. Make gcc -Wall happy.
* Some extra flags that an HPUX user wants me to add.Guido van Rossum1996-12-051-2/+2
|
* Tentative changes to make this work better on 64-bit machines.Guido van Rossum1996-12-051-3/+66
| | | | | 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.
* New permission notice, includes CNRI.Guido van Rossum1996-10-2538-495/+761
|
* Forget about Ellipses b/w compatibility.Guido van Rossum1996-10-161-2/+0
|
* Ellipses -> Ellipsis rename (the dictionary really says that it shouldGuido van Rossum1996-10-113-8/+10
| | | | | | | | 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.
* Sjoerd's thread changes (including down_sema typo fix).Guido van Rossum1996-10-088-18/+47
| | | | Note: waitflag not supported on NT.
* Added line number to most compile-time error messages.Guido van Rossum1996-09-171-88/+90

* Changes to setpythonpath():Guido van Rossum1996-09-101-4/+23
| | | | | Test for / as well as for SEP for MS filenames. Drop trailing separator from sys.path[0] for MS and Unix filenames.
