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 b3f7258f14 * Lots of small changes related to access.
* Added "access *: ...", made access work for class methods.
* Introduced subclass check: make sure that when calling
  ClassName.methodname(instance, ...), the instance is an instance of
  ClassName or of a subclass thereof (this might break some old code!)
1993-05-21 19:56:10 +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 25831652fd Several changes in one:
(1) dictionaries/mappings now have attributes values() and items() as
well as keys(); at the C level, use the new function mappinggetnext()
to iterate over a dictionary.

(2) "class C(): ..." is now illegal; you must write "class C: ...".

(3) Class objects now know their own name (finally!); and minor
improvements to the way how classes, functions and methods are
represented as strings.

(4) Added an "access" statement and semantics.  (This is still
experimental -- as long as you don't use the keyword 'access' nothing
should be changed.)
1993-05-19 14:50:45 +00:00
Guido van Rossum 6ac258d381 * pythonrun.c: Print exception type+arg *after* stack trace instead of
before it.
* ceval.c, object.c: moved testbool() to object.c (now extern visible)
* stringobject.c: fix bugs in and rationalize string resize in formatstring()
* tokenizer.[ch]: fix non-working code for lines longer than BUFSIZ
1993-05-12 08:24:20 +00:00
Guido van Rossum acbe8da4f8 (I suggest a recompile after getting this, the ceval.c bugfix may be crucial!)
* Makefile: removed superfluous AR=ar, fixed misleading comment.
* ceval.c: fixed debugging code; save/restore errors in locals_2_fast.
* intrcheck.c: for SunOS etc., turn off syscall resumption.
* regexpr.h: bump number of registers to 100.
1993-04-15 15:33:52 +00:00
Guido van Rossum 9575a44575 * Microscopic corrections to make things compile on the Cray APP.
* Removed one use of $> in Makefile and warned about others.
  Added configurable lines in Makefile to change CC and AR.
1993-04-07 14:06:14 +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 e537240c25 * Changed many files to use mkvalue() instead of newtupleobject().
* Fixcprt.py: added [-y file] option, do only files younger than file.
* modsupport.[ch]: added vmkvalue().
* intobject.c: use mkvalue().
* stringobject.c: added "formatstring"; renamed string* to string_*;
  ceval.c: call formatstring for string % value.
* longobject.c: close memory leak in divmod.
* parsetok.c: set result node to NULL when returning an error.
1993-03-16 12:15:04 +00:00
Guido van Rossum 6f5afc9a73 * ceval.c: ifdef out the last argument passing compat hack.
* Fixed memory leaks in socket, select and sv modules: mkvalue("O", v)
  does INCREF(v) so if v is brand new it should be XDECREF'd
1993-02-05 09:46:15 +00:00
Guido van Rossum 34679b7661 * Added Fixcprt.py: script to fix copyright message.
* various modules: added 1993 to copyright.
* thread.c: added copyright notice.
* ceval.c: minor change to error message for "+"
* stdwinmodule.c: check for error from wfetchcolor
* config.c: MS-DOS fixes (define PYTHONPATH, use DELIM, use osdefs.h)
* Add declaration of inittab to import.h
* sysmodule.c: added sys.builtin_module_names
* xxmodule.c, xxobject.c: fix minor errors
1993-01-26 13:33:44 +00:00
Guido van Rossum 775f4dacbc * Makefile: use cp -r to install the library
* ceval.c: use #ifdef COMPAT_HACKS instead of #if 0
* Makefile: fix to make clmodule.c compile;
  make config.o dependent on libpython.a (so date is always correct)
* timemodule.c: now sleep() also takes a float argument.
* posixmodule.c: added nice().
1993-01-09 17:18:52 +00:00
Sjoerd Mullender ed59d205a9 Various changes.
* Makefile: svmodule.c.proto and svgen.py are gone, svmodule.c came in
	their stead.  Also, pass -DUSE_DL flag to thread.c and give
	the user a possibility to add the -DDEBUG to just thread.c.
* ceval.c: init_save_thread() can be called more than once now.
* svgen.py, svmodule.c.proto, svmodule.c: Removed prototype file and
	replaced it by the generated file.
* thread.c: Added some more checks; added call to DL library when it
	is also used to tell it where the shared arena is so that DL
	can use some other area.
* threadmodule.c: Call init_save_thread from another place.  Also,
	added new function getlocklock() which does to lock objects
	what getfilefile does to file objects.
1993-01-06 13:36:38 +00:00
Guido van Rossum 5f59d6018e * mymalloc.h: always allocate one extra byte, since some malloc's
return NULL for malloc(0) or realloc(p, 0).  (This should be done
  differently than wasting one byte, but alas...)
* Moved "add'l libraries" option in Makefile to an earlier place.
* Remove argument compatibility hacks (b) and (c).
* Add grey2mono, dither2mono and mono2grey to imageop.
* Dup the fd in socket.fromfd().
* Added new modules mpz, md5 (by JH, requiring GNU MP 1.2).  Affects
  Makefile and config.c.
* socketmodule.c: added socket.fromfd(fd, family, type, [proto]),
  converted socket() to use of getargs().
1992-12-14 16:59:51 +00:00
Guido van Rossum d014ea6b5e * classobject.c: in instance_lenth, test result of call_object
for exception before using it.  Fixed a few other places where the
  outcome of calling sq_length wasn't tested for exceptions
  (bltinmodule.c, ceval.c).
1992-11-26 10:30:26 +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.)
1992-10-18 18:53:57 +00:00
Guido van Rossum 3165fe6a56 Modified most (but not yet all) I/O to always go through sys.stdout or
sys.stderr or sys.stdin, and to work with any object as long as it has
a write() (respectively readline()) methods.  Some functions that took
a FILE* argument now take an object* argument.
1992-09-25 21:59:05 +00:00
Guido van Rossum 99bec95482 Add some debugging features if DEBUG defined
(fetch the filename as a string so I can see it with dbx, and set f_lineno);
call abort() when detecting an "undetected" error.
1992-09-03 20:29:45 +00:00
Guido van Rossum f9a2d33f01 fix *serious* (new) bug in testbool: by default objects should test
true, not false!!!
1992-08-19 16:41:45 +00:00
Guido van Rossum e6eefc2231 * classobject.[ch], {float,long,int}object.c, bltinmodule.c:
coercion is now completely generic.
* ceval.c: for instances, don't coerce for + and *; * reverses
  arguments if left one is non-instance numeric and right one sequence.
1992-08-14 12:06:52 +00:00
Guido van Rossum 04691fc1c1 Changes so that user-defined classes can implement operations invoked
by special syntax: you can now define your own numbers, sequences and
mappings.
1992-08-12 15:35:34 +00:00
Guido van Rossum ff4949eeee * Makefile: cosmetics
* socketmodule.c: get rid of makepair(); fix makesocketaddr to fix
  broken recvfrom()
* socketmodule: get rid of getStrarg()
* ceval.h: move eval_code() to new file eval.h, so compile.h is no
  longer needed.
* ceval.c: move thread comments to ceval.h; always make save/restore
  thread functions available (for dynloaded modules)
* cdmodule.c, listobject.c: don't include compile.h
* flmodule.c: include ceval.h
* import.c: include eval.h instead of ceval.h
* cgen.py: add forground(); noport(); winopen(""); to initgl().
* bltinmodule.c, socketmodule.c, fileobject.c, posixmodule.c,
  selectmodule.c:
  adapt to threads (add BGN/END SAVE macros)
* stdwinmodule.c: adapt to threads and use a special stdwin lock.
* pythonmain.c: don't include getpythonpath().
* pythonrun.c: use BGN/END SAVE instead of direct calls; also more
  BGN/END SAVE calls etc.
* thread.c: bigger stack size for sun; change exit() to _exit()
* threadmodule.c: use BGN/END SAVE macros where possible
* timemodule.c: adapt better to threads; use BGN/END SAVE; add
  longsleep internal function if BSD_TIME; cosmetics
1992-08-05 19:58:53 +00:00
Guido van Rossum 1984f1e1c6 * Makefile adapted to changes below.
* split pythonmain.c in two: most stuff goes to pythonrun.c, in the library.
* new optional built-in threadmodule.c, build upon Sjoerd's thread.{c,h}.
* new module from Sjoerd: mmmodule.c (dynamically loaded).
* new module from Sjoerd: sv (svgen.py, svmodule.c.proto).
* new files thread.{c,h} (from Sjoerd).
* new xxmodule.c (example only).
* myselect.h: bzero -> memset
* select.c: bzero -> memset; removed global variable
