* {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
* 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!)
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.
* 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!!!)
* 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.
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.
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.
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.
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.
* 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.
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().
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.)
* 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!)
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.
(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.)
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
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.]
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.
* 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
* 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.
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.
* 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
stdwinmodule.c: wsetfont can now return an error

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
* 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.
* 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.)
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.
* 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.
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).
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)
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.
* 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.

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
* 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
arguments crashed in INCREF() calls which should be XINCREF() calls.
timemodule.c: fix for SEQUENT port (sys/select, struct timezone) by
Jaap Vermeulen
xxobject.c: include modsupport.h
must (pretend to) support all operations except assignments;
if you don't want to support an operation you have to provide
a dummy function that raises an exception...
