the number of children of a node exceeds the max possible value for
the short that is used to count them. The Python runtime converts
this parser error into the SyntaxError "expression too long."
need two phase init or fini of the builtin module. Change the call of
_PyBuiltin_Init_1() to _PyBuiltin_Init(). Add a call to
init_exceptions().
Py_Finalize(): Don't call _PyBuiltin_Fini_1(). Instead call
fini_exceptions() but move this to before the thread state is
cleared.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode. I'm also holding back on his
change to main.c, which seems unnecessary to me.)
remaining object references if the environment variable PYTHONDUMPREFS
exists. The default behaviour caused problems for background or
otherwise invisible processes that use the debug build of Python.
v temporary variable was never decref'd. Test this by starting up the
interpreter, hitting C-c, then immediately exiting.
Same potential leak can occur if error is E_NOMEM, since the return is
done in the case block. Added Py_XDECREF(v); to both blocks, just
before the return.
think we have our own DOS box (i.e. we're not started from a command
line shell), we print a message and wait for the user to hit a key
before the DOS box is closed.
The hacky heuristic for determining whether we have our *own* DOS box
(due to Mark Hammond) is to test whether we're on line zero...
- Add Py_FrozenFlag, intended to suppress error messages fron
getpath.c in frozen binaries.
- Add Py_GetPythonHome() and Py_SetPythonHome(), intended to allow
embedders to force a different PYTHONHOME.
- Add new interface PyErr_PrintEx(flag); same as PyErr_Print() but
flag determines whether sys.last_* are set or not. PyErr_Print()
now simply calls PyErr_PrintEx(1).
1) The __builtins__ variable in the __main__ module is set to the
__builtin__ module instead of its __dict__.
2) Get rid of the SIGHUP and SIGTERM handlers. They can't be made to
work reliably when threads may be in use, they are Unix specific, and
Python programmers can now program this functionality is a safer way
using the signal module.
Setting interp->builtins to the __builtin__ module instead of to its
dictionary had the unfortunate side effect of always running in
restricted execution mode :-(
I will check in a different way of setting __main__.__builtins__ to
the __builtin__ module later.
Also, there was a typo -- a comment was unfinished, and as a result
some finalizations were not being executed.
In Bart Simpson style,

- The interp->builtins variable (and hence, __main__.__builtins__) is
once again initialized to the built-in *module* instead of its
dictionary.
- The finalization order is once again changed. Signals are finalized
relatively early, because (1) it DECREF's the signal handlers, and if
a signal handler happens to be a bound method, deleting it could cause
problems when there's no current thread around, and (2) we don't want
to risk executing signal handlers during finalization.
- Changed semantics for initialized flag (again); forget the ref
counting, forget the fatal errors -- redundant calls to
Py_Initialize() or Py_Finalize() calls are simply ignored.
- Automatically import site.py on initialization, unless a flag is set
not to do this by main().
the -X command line option.
Py_Initialize(): Handle the two phase initialization of the built-in
module.
Py_Finalize(): Handle the two phase finalization of the built-in
module.
parse_syntax_error(): New function which parses syntax errors that
PyErr_Print() will catch. This correctly parses such errors
regardless of whether PyExc_SyntaxError is an old-style string
exception or new-fangled class exception.
PyErr_Print(): Many changes:
1. Normalize the exception.
2. Handle SystemExit exceptions which might be class based. Digs
the exit code out of the "code" attribute. String based
SystemExit is handled the same as before.
3. Handle SyntaxError exceptions which might be class based. Digs
the various information bits out of the instance's attributes
(see parse_syntax_error() for details). String based
SyntaxError still works too.
4. Don't write the `:' after the exception if the exception is
class based and has an empty string str() value.
for more!).
- The global flags that can be set from environment variables are now
set in Py_Initialize (except the silly Py_SuppressPrint, which no
longer exists). This saves duplicate code in frozenmain.c and main.c.
- Py_GetProgramName() is now here; added Py_SetProgramName(). An
embedding program should no longer provide Py_GetProgramName(),
instead it should call Py_SetProgramName() *before* calling
Py_Initialize().
Py_FdIsInteractive(). The flag is supposed to be set by the -i
command line option. The function is supposed to be called instead of
isatty(). This is used for Lee Busby's wish #1, to have an option
that pretends stdin is interactive even when it really isn't.
- Assume files of types 'PYC ' and 'APPL' are compiled python code
- For mwerks, show status line when program has terminated while
keeping window open.
bltinmodule.c: fixed coerce() nightmare in ternary pow().
modsupport.c (initmodule2): pass METH_FREENAME flag to newmethodobject().
pythonrun.c: move flushline() into and around print_error().
mac/macsetfiletype.c: changes by Jack to execute .pyc file passed
as command line argument. On the Mac .pyc files are given a
special type so they can be double-clicked
* 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.
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.
* 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.
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.
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
* 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.
* 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
* 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
