Guido van Rossum 6610ad9d6b Added 1995 to copyright message.
floatobject.c: fix hash().
methodobject.c: support METH_FREENAME flag bit.
1995-01-04 19:07:38 +00:00
Guido van Rossum d7047b395e Lots of minor changes. Note for mappingobject.c: the hash table pointer
can now be NULL.

Guido van Rossum 1d5735e846 Merge back to main trunk 1994-08-30 08:27:36 +00:00
Sjoerd Mullender f64992e95d * clmodule.c (doParams): free PVbuffer in error condition.
* frameobject.c (newframeobject): initialize ob_type if taking entry
  from the free list, since it is zeroed out when DEBUG is defined.
1993-08-03 15:11:36 +00:00
Guido van Rossum eb6b33a837 * classobject.c: in instance_getattr, don't make a method out of a
function found as instance data.
* socketmodule.c: added 'flags' argument sendto/recvfrom, rewrite
  argument parsing in send/recv.
* More changes related to access (terminology change: owner instead of
  class; allow any object as owner; local/global variables are owned
  by their dictionary, only class/instance data is owned by the class;
  "from...import *" now only imports objects with public access; etc.)
1993-05-25 09:38:27 +00:00
Guido van Rossum 81daa32c15 Access checks now work, at least for instance data (not for methods
yet).  The class is now passed to eval_code and stored in the current
frame.  It is also stored in instance method objects.  An "unbound"
instance method is now returned when a function is retrieved through
"classname.funcname", which when called passes the class to eval_code.
1993-05-20 14:24:46 +00:00
Guido van Rossum 5b7221849e * Fixed some subtleties with fastlocals. You can no longer access
f_fastlocals in a traceback object (this is a core dump hazard
  if there are <nil> entries), but instead eval_code() merges the fast
  locals back into the locals dictionary if it looks like the local
  variables will be retained.  Also, the merge routines save
  exceptions since this is sometimes needed (alas!).

* Added id() to bltinmodule.c, which returns an object's address
  (identity).  Useful to walk arbitrary data structures containing
  cycles.

* Added compile() to bltinmodule.c and compile_string() to
  pythonrun.[ch]: support to exec/eval arbitrary code objects.  The
  code that defaults globals and locals is moved from run_node in
  pythonrun.c (which is now identical to eval_node) to eval_code in
  ceval.c.  [XXX For elegance a clean-up session is necessary.]
1993-03-30 17:46:03 +00:00
Guido van Rossum 8b17d6bd89 Changes to speed up local variables enormously, by avoiding dictionary
lookup (opcode.h, ceval.[ch], compile.c, frameobject.[ch],
pythonrun.c, import.c).  The .pyc MAGIC number is changed again.
Added get_menu_text to flmodule.
1993-03-30 13:18:41 +00:00
Guido van Rossum 9bfef44d97 * Changed all copyright messages to include 1993.
* Stubs for faster implementation of local variables (not yet finished)
* Added function name to code object.  Print it for code and function
  objects.  THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version
  number has changed accordingly)
* Print address of self for built-in methods
* New internal functions getattro and setattro (getattr/setattr with
  string object arg)
* Replaced "dictobject" with more powerful "mappingobject"
* New per-type functio tp_hash to implement arbitrary object hashing,
  and hashobject() to interface to it
* Added built-in functions hash(v) and hasattr(v, 'name')
* classobject: made some functions static that accidentally weren't;
  added __hash__ special instance method to implement hash()
* Added proper comparison for built-in methods and functions
1993-03-29 10:43:31 +00:00
Guido van Rossum a9e7dc1081 * bltinmodule.c: added built-in function cmp(a, b)
* flmodule.c: added {do,check}_only_forms to fl's list of functions;
  and don't print a message when an unknown object is returned.

* pythonrun.c: catch SIGHUP and SIGTERM to do essential cleanup.

* Made jpegmodule.c smaller by using getargs() and mkvalue() consistently.

* Increased parser stack size to 500 in parser.h.

* Implemented custom allocation of stack frames to frameobject.c and
  added dynamic stack overflow checks (value stack only) to ceval.c.
  (There seems to be a bug left: sometimes stack traces don't make sense.)
