Guido van Rossum 747596a491 When a recycled frame has more local+stack slots than needed, 
give the extra slots to the stack rather than than forgetting about
them (this reduces the number of reallocs done).
 1997-01-24 04:00:21 +00:00
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.
 1997-01-23 19:39:29 +00:00
Guido van Rossum e0e696282f Added PyCObject_Import. 1997-01-22 20:48:48 +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 3bb63a8dbe Bugfix: remove ref to fast before it's defined. 1997-01-20 04:29:16 +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.

Guido van Rossum a412d24be0 Intern the various string objects created to speed up lookups. 1997-01-18 07:59:12 +00:00
Guido van Rossum b56933ed2e Intern the strings "__builtins__". 1997-01-18 07:58:41 +00:00
Guido van Rossum c6d0670f1b Intern the strings created in getattr() and setattr(). 1997-01-18 07:57:16 +00:00
Guido van Rossum 2a61e7428d String interning. 1997-01-18 07:55:05 +00:00
Guido van Rossum 792fd435ec Comment out extend_stack() -- it is no longer needed. 1997-01-17 21:07:57 +00:00
Guido van Rossum 7d18159614 Rewrote lookmapping() according to suggestions by Jyrki Alakuijala. 1997-01-16 21:06:45 +00:00
Guido van Rossum 6f72f97c03 Increased buffer sizes used by hex() and oct() -- on 64-bit or 128-bit 
machines, the string may get longer than 20 characters!
 1997-01-14 15:43:41 +00:00
Guido van Rossum ebee0256f3 Changed hex() and oct() again, to never emit a '-' sign. 1997-01-12 19:48:03 +00:00
Guido van Rossum 919cf1aff1 New, better hash for floating point and complex 1997-01-11 19:26:21 +00:00
Guido van Rossum 80dd9b6672 Subtle change to hex/oct formatting so the largest negative number 
does not receive a minus sign.
 1997-01-10 17:39:30 +00:00
Guido van Rossum 541cdd84ac Fix overflow test for multiply to catch some cases it missed. 
Added warning about dependency of float/complex hash on int hash.
 1997-01-06 22:53:20 +00:00
Guido van Rossum 53756b1097 Added PyLong_FromUnsignedLong() and PyLong_AsUnsignedLong(). 1997-01-03 17:14:46 +00:00
Guido van Rossum babab6869f Removed all traces of accessobject.c. 1996-12-25 19:22:49 +00:00
Barry Warsaw f90eddef5d PySequence_Index(): set exception when object is not found in 
sequence, otherwise

operator.indexOf([4, 3, 2, 1], 9) would raise a SystemError!

Note: it might be wise to double check all these functions.  I haven't
done that yet.
 1996-12-18 19:32:18 +00:00
Guido van Rossum 0969ad213d Better tuple hash function. 1996-12-16 17:55:46 +00:00
Guido van Rossum cc15b42e59 Change comment about MINSIZE -- 10 is optimal for Python. 1996-12-16 03:32:39 +00:00
Guido van Rossum 3176bb1df2 Some more tuning of quicksort: use pointers instead of indexing. 1996-12-11 23:57:39 +00:00
Guido van Rossum 3f236dee3a Added new quicksort implementation, tailored to sorting arrays of 
object pointers.  Should be a bit faster than the C library's qsort(),
and doesn't have the prohibition on recursion that Solaris qsort() has
in the threaded version of their C library.

Thanks to discussions with Tim Peters.
 1996-12-10 23:55:39 +00:00

Guido van Rossum 472c04f18f Fix newlongobject so it will work for 64-bit as well as 32-bit hardware 
(although for 32-bit hardware it's a bit slower than it was).

Make gcc -Wall happy.
 1996-12-05 21:57:21 +00:00
Guido van Rossum a0a69b8b42 Experimental new implementation of dictionary comparison. This 
defines that a shorter dictionary is always smaller than a longer one.
For dictionaries of the same size, the smallest differing element
determines the outcome (which yields the same results as before,
without explicit sorting).
 1996-12-05 21:55:55 +00:00
Guido van Rossum 685a38ea94 Make gcc -Wall happy. 1996-12-05 21:54:17 +00:00

for consistency with the way other characters are compared.
 1996-10-23 14:19:40 +00:00
Guido van Rossum 8bcf369cf9 Support passing in an empty dictionary of keywords to newinstanceobject. 1996-10-21 15:12:32 +00:00
Guido van Rossum e449af7da9 Ellipses -> Ellipsis rename (the dictionary really says that it should 
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.
 1996-10-11 16:25:41 +00:00
Guido van Rossum 336c699236 Fix subtle bug detected by Jim F. 1996-09-30 22:00:50 +00:00

may get inc_count sanity check abort).
 1995-09-18 10:49:04 +00:00
Sjoerd Mullender 6ec3c653da Implemented two new functions in sys: 
getcounts() returns a list of counts of allocations and
		deallocations for all different object types.
	getobjects(n [, type ]) returns a list of recently allocated
		and not-yet-freed objects of the given type (all
		objects if no type given).  Only the n most recent
		(all if n==0) objects are returned.
getcounts is only available if compiled with -DCOUNT_ALLOCS,
getobjects is only available if compiled with -DTRACE_REFS.  Note that
everything must be compiled with these options!

Guido van Rossum 29ca26eebf added getattr(), supporting __doc__ and _name__ 1995-01-07 11:58:15 +00:00
Guido van Rossum 016564ab51 attribute-less object is AttributeError, not TypeError 1995-01-07 11:54:44 +00:00
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 efc8713428 * Objects/mappingobject.c (mappingremove): don't call 
lookmapping() for empty dictionary
 1995-01-02 19:42:39 +00:00
Guido van Rossum d7047b395e Lots of minor changes. Note for mappingobject.c: the hash table pointer 
can now be NULL.
 1995-01-02 19:07:15 +00:00
Guido van Rossum bb3c5f7406 fix comparison of instances without _-cmp__ 1994-11-10 22:31:02 +00:00
Sjoerd Mullender b9a6d12498 Comparison of two class instances without __cmp__ or __rcmp__ methods 
was broken.
 1994-10-19 15:11:52 +00:00
Guido van Rossum 03093a248d * Include/classobject.h, Objects/classobject.c, Python/ceval.c: 
entirely redone operator overloading.  The rules for class
	instances are now much more relaxed than for other built-in types
	(whose coerce must still return two objects of the same type)

	* Objects/floatobject.c: add overflow check when converting float
	to int and implement truncation towards zero using ceil/float

	* Objects/longobject.c: change ValueError to OverflowError when
	converting to int

	* Objects/rangeobject.c: modernized

	* Objects/stringobject.c: use HAVE_LIMITS instead of __STDC__

	* Objects/xxobject.c: changed to use new style (not finished?)
 1994-09-28 15:51:32 +00:00
Guido van Rossum 9776adf565 rearranged code in debugging version of DELREF to avoid touching data 
after it has been freed.
 1994-09-07 14:36:45 +00:00
Guido van Rossum 52ca98a390 Yet another version (by me) of __getattr__ etc. 1994-09-05 07:32:29 +00:00
Guido van Rossum e773754ae5 Mods (really diffs to 2.29) by Michael Scharf for alternative __getattr__ etc. 1994-09-05 07:31:41 +00:00
Guido van Rossum 1d5735e846 Merge back to main trunk 1994-08-30 08:27:36 +00:00
Guido van Rossum 013142a95f fix nasty bug in resizing (formatstring) 1994-08-30 08:19:36 +00:00
Guido van Rossum bf8c0e336f mods by Andrew Kuchling to implement 
pow(x,y,z) == pow(x,y)%z, but without incurring overflow
Correct problems found by THINK C 6.0
 1994-08-29 12:48:32 +00:00
Guido van Rossum eb1fafcec1 New patches by Andrew to fix various problems 
Add cast for Lance
 1994-08-29 12:47:19 +00:00
Guido van Rossum 6cd2fe043b Correct problems found by THINK C 6.0 1994-08-29 12:45:32 +00:00
Guido van Rossum f0171a1626 * configure.in, */Makefile*.in: OPT can now be specified in the 
env at configure time and will then be put in all Makefiles as
	default
	* */Makefile*.in: remove lib*.a before adding to it
 1994-08-23 14:06:18 +00:00
Guido van Rossum 91ab4a8353 If an attribute is deleted, __setattr__ is called with 2 instead of 3 
arguments (adding __delattr__ was deemed too much overhead)
 1994-08-16 22:13:47 +00:00
Guido van Rossum 0b7d02a36f New patches by Andrew to fix various problems 1994-08-12 12:52:35 +00:00
Guido van Rossum e149fa2a1e * Objects/classobject.c, Include/classobject.h: added __getattr__ 
and __setattr__ support to override getattr(x, name) and
	setattr(x, name, value) for class instances.  This uses a special
	hack whereby the class is supposed to be static: the __getattr__
	and __setattr__ methods are looked up only once and saved in the
	instance structure for speed
 1994-08-12 12:49:46 +00:00
Guido van Rossum b6775db241 Merge alpha100 branch back to main trunk 1994-08-01 11:34:53 +00:00
Guido van Rossum 2e1d433e43 Added getmaxint() so sys can initialize sys.maxint. 
Added Makefile.in.
 1993-12-24 10:22:45 +00:00
Guido van Rossum 7d6aa51b56 * rangeobject.[ch], bltinmodule.c: incorporate new version of range 
object (unchanged from source except "range" -> "xrange").
 1993-12-21 22:50:31 +00:00
Guido van Rossum 455b87d457 New file 1993-12-20 11:43:21 +00:00
Guido van Rossum 590baa4a7a * import.c (get_module): pass .py filename to parse_file, not .pyc filename! 
* funcobject.c (func_repr): don't call getstringvalue(None) for anonymous
  functions.
* bltinmodule.c: removed lambda (which is now a built-in function);
  removed implied lambda for string arg to filter/map/reduce.
* Grammar, graminit.[ch], compile.[ch]: replaced lambda as built-in
  function by lambda as grammar entity: instead of "lambda('x: x+1')" you
  write "lambda x: x+1".
* Xtmodule.c (checkargdict): return 0, not NULL, for error.
 1993-11-30 13:40:46 +00:00
Guido van Rossum 8732d6aeea Fix lay-out of previous fix. 1993-11-23 17:54:03 +00:00
Guido van Rossum b376a4ad18 * timemodule.c: Add hack for Solaris 2. 
* posixmodule.c: don't prototype getcwd() -- it's not portable...
* mappingobject.c: double-check validity of last_name_char in
  dict{lookup,insert,remove}.
* arraymodule.c: need memmove only for non-STDC Suns.
* Makefile: comment out HTML_LIBS and XT_USE by default
* pythonmain.c: don't prototype getopt() -- it's not standardized
* socketmodule.c: cast flags arg to {get,set}sockopt() and addrbuf arg to
  recvfrom() to (ANY*).
* pythonrun.c (initsigs): fix prototype, make it static
* intobject.c (LONG_BIT): only #define it if not already defined
* classobject.[ch]: remove all references to unused instance_convert()
* mappingobject.c (getmappingsize): Don't return NULL in int function.
 1993-11-23 17:53:17 +00:00
Guido van Rossum c45611d0e3 * import.c (get_module): total rewrite, to ensure proper search order: for 
each dir in sys.path, try each possible extension.  (Note: C extensions
  are loaded before Python modules in the same directory, to allow having
  a C version used when dynamic loading is supported and a Python version
  as a back-up.)
* import.c (reload_module): test for error from getmodulename()
* moduleobject.c: implement module name as dict entry '__name__' instead
  of special-casing it in module_getattr(); this way a module (or
  function!) can access its own module name, and programs that know what
  they are doing can rename modules.
* stdwinmodule.c (initstdwin): strip ".py" suffix of argv[0].
 1993-11-17 22:58:56 +00:00
Guido van Rossum 71e57d090d Fix the fix :-( 1993-11-11 15:03:51 +00:00
Guido van Rossum 6938a297da Three micro fixes to formatstring 1993-11-11 14:51:57 +00:00
Guido van Rossum 52f2c05401 * parsermodule.c, Makefile, config.c: rudimentary interface to the Python 
parser.
* mappingobject.c (lookmapping): 'freeslot' was never used due to a bug in
  the code.
 1993-11-10 12:53:24 +00:00
Guido van Rossum a3d78fb268 * posixmodule.c: added set{uid,gid}. 
* {tuple,list,mapping,array}object.c: call printobject with 0 for flags
* compile.c (parsestr): use quote instead of '\'' at one crucial point
* arraymodule.c (array_getattr): Added __members__ attribute
 1993-11-10 09:23:53 +00:00
Guido van Rossum c600411755 * mpzmodule.c: removed redundant mpz_print function. 
* object.[ch], bltinmodule.c, fileobject.c: changed str() to call
  strobject() which calls an object's __str__ method if it has one.
  strobject() is also called by writeobject() when PRINT_RAW is passed.
* ceval.c: rationalize code for PRINT_ITEM (no change in function!)
* funcobject.c, codeobject.c: added compare and hash functionality.
  Functions with identical code objects and the same global dictionary are
  equal.  Code objects are equal when their code, constants list and names
  list are identical (i.e. the filename and code name don't count).
  (hash doesn't work yet since the constants are in a list and lists can't
  be hashed -- suppose this should really be done with a tuple now we have
  resizetuple!)
 1993-11-05 10:22:19 +00:00
Guido van Rossum 2e8f8a398e Added compare operations for functions and code objects. 
(Also hash, but it doesn't work yet.)
 1993-11-05 10:20:10 +00:00
Guido van Rossum 4199facacd Added getmappingsize(). (Needed by previous checkin of posixmodule.c) 1993-11-05 10:18:44 +00:00
Guido van Rossum b73cc04e62 * ceval.c, longobject.c, methodobject.c, listnode.c, arraymodule.c, 
pythonrun.c: added static forward declarations
* pythonrun.h, ceval.h, longobject.h, node.h: removed declarations of
  static routines
 1993-11-01 16:28:59 +00:00
Guido van Rossum 82d410e733 * fileobject.c (softspace): fix bug if called with NULL file. 1993-11-01 16:26:16 +00:00
Guido van Rossum 2586bf0a34 * rangeobject.{c,h}, bltinmodule.c: removed non-essential ops from range 
object.
 1993-11-01 16:21:44 +00:00
Sjoerd Mullender 615194a352 Fixed bugs in resizetuple and extended the interface. 
Added ifdefs in stringobject.c for shared strings of length 1.
Renamed free_list in tupleobject.c to free_tuples.
 1993-11-01 13:46:50 +00:00
Guido van Rossum dc4b93db70 * listobject.c (list_ass_slice): XDECREF instead of DECREF so 
setlistslice() can be used to cut the unused part out of a freshly made
  slice (as done by bagof()).  [needed by the next mod!]
* structural changes to bagof(), map() etc.
 1993-10-27 14:56:44 +00:00
Guido van Rossum 12d12c5faf * compile.[ch]: support for lambda() 
* PROTO.h, mymalloc.h: added #ifdefs for TURBOC and GNUC.
* allobjects.h: added #include "rangeobject.h"
* Grammar: added lambda_input; relaxed syntax for exec.
* bltinmodule.c: added bagof, map, reduce, lambda, xrange.
* tupleobject.[ch]: added resizetuple().
* rangeobject.[ch]: new object type to speed up range operations (not
  convinced this is needed!!!)
 1993-10-26 17:58:25 +00:00
Guido van Rossum 444fc7c90c Add some necessary casts; use double quotes to represent strings in 
some cases.
 1993-10-26 15:25:16 +00:00
Guido van Rossum 72481a3497 Changes to make range checks portable to 64-bit machines. 1993-10-26 15:21:51 +00:00
Guido van Rossum 5a2a683e72 * filemodule.c: added writelines() -- analogous to readlines() 
* import.c: fixed core dump when out-of-date .pyc file encountered (again!)
 1993-10-25 09:59:04 +00:00
Sjoerd Mullender 52c1f51554 import.c: When something is wrong with the .pyc, properly open the .py 
file.
object.c: Write allocation statistics to stderr.
 1993-10-25 08:40:52 +00:00
Sjoerd Mullender 3bb8a05947 Several optimizations and speed improvements. 
cstubs: Use Matrix type instead of float[4][4].
 1993-10-22 12:04:32 +00:00
Guido van Rossum db3165e655 * bltinmodule.c: removed exec() built-in function. 
* Grammar: add exec statement; allow testlist in expr statement.
* ceval.c, compile.c, opcode.h: support exec statement;
  avoid optimizing locals when it is used
* fileobject.{c,h}: add getfilename() internal function.
 1993-10-18 17:06:59 +00:00
Sjoerd Mullender 842d2ccdcd intobject.c: Save references to small integers, so that they can be 
shared.  The default is to save references to the integers in
	the range -1..99.  The lower limit can be set by defining
	NSMALLNEGINTS (absolute value of smallest integer to be saved)
	and NSMALLPOSINTS (1 more than the largest integer to be
	saved).
tupleobject.c: Save a reference to the empty tuple to be returned
	whenever a tuple of size 0 is requested.  Tuples of size 1
	upto, but not including, MAXSAVESIZE (default 20) are put in
	free lists when deallocated.  When MAXSAVESIZE equals 1, only
	share references to the empty tuple, when MAXSAVESIZE equals
	0, don't include the code at all and revert to the old
	behavior.
object.c: Print some more statistics when COUNT_ALLOCS is defined.
 1993-10-15 16:18:48 +00:00
Guido van Rossum 21d335ed9e Makefile, import.c: Lance's alternative module search (allow .pyc file 
without .py file); Bill's dynamic loading for SunOS using shared
libraries.

pwdmodule.c (mkgrent): remove DECREF of uninitialized variable.

classobject.c (instance_getattr): Fix case when class lookup returns
unbound method instead of function.
 1993-10-15 13:01:11 +00:00
Sjoerd Mullender a9c3c22c33 * Extended X interface: pixmap objects, colormap objects visual objects, 
image objects, and lots of new methods.
* Added counting of allocations and deallocations of builtin types if
  COUNT_ALLOCS is defined.  Had to move calls to NEWREF down in some
  files.
* Bug fix in sorting lists.
 1993-10-11 12:54:31 +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 1fc238a813 Minor fixes / changes for Mac compatibility. 1993-07-29 08:25:09 +00:00
Guido van Rossum ed18fdc9fc * accessobject.c (ownercheck): allow a base class access to protected 
objects of its derived classes; allow anything that has an attribute
  named "__privileged__" access to anything.
* object.[ch]: added hasattr() -- test whether getattr() will succeed.
 1993-07-11 19:55:34 +00:00
Guido van Rossum f1dc566328 * Makefile: added all: and default: targets. 
* many files: made some functions static; removed "extern int errno;".
* frozenmain.c: fixed bugs introduced on 24 June...
* flmodule.c: remove 1.5 bw compat hacks, add new functions in 2.2a
  (and some old functions that were omitted).
* timemodule.c: added MSDOS floatsleep version .
* pgenmain.c: changed exit() to goaway() and added defn of goaway().
* intrcheck.c: add hack (to UNIX only) so interrupting 3 times
  will exit from a hanging program.  The second interrupt prints
  a message explaining this to the user.
 1993-07-05 10:31:29 +00:00
Guido van Rossum 234f942aef * Added gmtime/localtime/mktime and SYSV timezone globals to timemodule.c. 
Added $(SYSDEF) to its build rule in Makefile.
* cgensupport.[ch], modsupport.[ch]: removed some old stuff.  Also
  changed files that still used it...  And made several things static
  that weren't but should have been...  And other minor cleanups...
* listobject.[ch]: add external interfaces {set,get}listslice
* socketmodule.c: fix bugs in new send() argument parsing.
* sunaudiodevmodule.c: added flush() and close().
 1993-06-17 12:35:49 +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 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 8a0c3456c2 Fix bug in class instance hash (forgot to clear error condition). 1993-04-08 12:56:19 +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 4b1302bd1d Generalized version of dictionaries, with compatibility hacks. 1993-03-27 18:11:32 +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 9e51f9bec8 bltinmodule.c: added round(x, [n]); coerce() of two class instances 
will try to coerce anyway.
classobject.c: instance 'nonzero' should first try __nonzero__
only then __len__.
 1993-02-12 16:29:05 +00:00
Guido van Rossum bf80e5407f * stdwinmodule.c: various new commands: setwin{pos,size}, 
listfontnames, bitmap ops.
* listobject.c: use mkvalue() when possible; avoid weird error when
  calling append() without args.
* modsupport.c: new feature in getargs(): if the format string
  contains a semicolor the string after that is used as the error
  message instead of "bad argument list (format %s)" when there's an
  error.
 1993-02-08 15:49:17 +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 0b0db8e3a0 Added separate main program for the Mac: macmain.c 
stdwinmodule.c: wsetfont can now return an error
Makefile: add CL_USE and CL_LIB*S; config.c: move CL part around
New things in imgfile; also in Makefile.
longobject.c: fix comparison of negative long ints...  [REAL BUG!]
marshal.c: add dumps() and loads() to read/write strings
timemodule.c: make sure there's always a floatsleep()
posixmodule.c: rationalize struct returned by times()
Makefile: add test target, disable imgfile by default
thread.c: Improved coexistance with dl module (sjoerd)
stdwinmodule.c: Change include stdwin.h if macintosh
rotormodule.c: added missing last argument to RTR_?_region calls
confic.c: merged with configmac.c, added 1993 to copyright message
fileobject.c: int compared to NULL in writestring(); change fopenRF ifdef
timemodule.c: simplify times() using mkvalue; include myselect.h
  earlier (for sequent).
posixmodule: for sequent, include unistd.h instead of explicit
  extern definitions and don't define rename()
Makefile: change misleading/wrong MD5 comments
 1993-01-21 16:07:51 +00:00
Guido van Rossum e35399ea7b Checking in last-minute changes that are already part of release 0.9.8 1993-01-10 18:33:56 +00:00
Guido van Rossum a2b7f40513 * Configure.py: use #!/usr/local/bin/python 
* posixmodule.c: move extern function declarations to top
* listobject.c: cmp() arguments must be void* if __STDC__
* Makefile, allobjects.h, panelmodule.c, modsupport.c: get rid of
  strdup() -- it is a portability risk
* Makefile: enclosed ranlib command in parentheses for Sequent Make
  which aborts if the command is not found even if '-' is present
* timemodule.c: time() returns a floating point number, in microsecond
  precision if BSD_TIME is defined.
 1993-01-04 09:09:59 +00:00
Guido van Rossum de788b8261 fileobject.c: fix nasty bug; Makefile; turn on STROP and change lint flags. 1992-12-22 14:24:04 +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 7066dd75c5 * Makefile: added IMGFILE; moved some stuff around. 
* flmodule.c: added some missing functions; changed readonly flags of
  some data members based upon FORMS documentation.
* listobject.c: fixed int/long arg lint bug (bites PC compilers).
* several: removed redundant print methods (repr is good enough).
* posixmodule.c: added (still experimental) process group functions.
 1992-09-17 17:54:56 +00:00
Guido van Rossum 1899c2e055 Made builtins int(), long(), float(), oct() and hex() more generic. 1992-09-12 11:09:23 +00:00
Guido van Rossum 94472a0374 classobject.c moduleobject.c stdwinmodule.c xxobject.c: 
raise AttributeError, not KeyError, when attribute deletion fails.
sunaudiodevmodule.c: check for deletion before calling setmember.
 1992-09-04 09:45:18 +00:00
Guido van Rossum ba3690cd09 Remove outdated warning in comments. 1992-09-03 20:44:36 +00:00
Guido van Rossum 67daef567f Remove bogus type-and-refcnt setting from newsizedstringobject(). 1992-09-03 20:44:02 +00:00
Guido van Rossum ebc8c51cde Compare instance methods by comparing the object and the function. 1992-09-03 20:39:51 +00:00
Guido van Rossum 2e8f6140ff If a type has a repr function but no print function, printing it now 
calls the repr function.  When the refcount is bad, don't print
the object at all (chances of crashes).
Changes to checking and printing of references: the consistency
check is somewhat faster; don't print strings referenced once
(most occur in function's name lists).
 1992-09-03 20:32:55 +00:00
Guido van Rossum 1e28e5e596 * renamed malloc.h mymalloc.h, and added MALLARG as the type of the 
argument to malloc() (size_t or unsigned int)

* listobject.c: check for overflow of the size of the object,
  so things like range(0x7fffffff) will raise MemoryError instead
  of calling malloc() with -4 (and then crashing -- malloc's fault)
 1992-08-19 16:46:30 +00:00
Guido van Rossum 2c475427c2 oct(0) should return '0', not '00' 1992-08-14 15:13:07 +00:00
Guido van Rossum 6d946f98bd * macmodule.c: include allobjects.h, not .c 
* timemodule.c: the mac has no unistd.h
* classobject.c: fixed several cases of return NULL that should be
  return -1 !!!
 1992-08-14 13:49:30 +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 70d7a310a9 * xxobject.c: added tp_as_number, tp_as_sequence, tp_as_mapping to 
the type object.
 1992-08-14 12:04:19 +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

Guido van Rossum d7297e61df Makefile: added instann rules and $(*DEST*) defines. 
fileobject.c: report more moeaningful error for I/O on closed files;
user getargs() everywhere.
 1992-07-06 14:19:26 +00:00
Guido van Rossum ed233a5696 Changes for new UNIX-specific built-in module 'select' and new header for 
interfaces to variants of select() system call, "myselect.h".  This includes
adding fileno() methods to files, sockets and stdwin.
 1992-06-23 09:07:03 +00:00
Guido van Rossum 5dc8eb0914 sysmodule.c: calling sys.settrace() or sys.setprofile() without 
arguments crashed in INCREF() calls which should be XINCREF() calls.
