This BUGS list hasn't been updated since the release of Python 1.2!
It is useless. My real bugs database is currently being maintained with GNATS.

THIS LIST DOES NOT CLAIM COMPLETENESS.
|
||||
|
||||
==> Status indicators: (-) not fixed; (*) fixed; (?) not sure.
|
||||
|
||||
======================================================================
|
||||
|
||||
Problems that are difficult to solve
|
||||
------------------------------------
|
||||
|
||||
(-) "f()=0" generates syntax error msg without line number
|
||||
|
||||
(-) tkinter seems to leave an exception around sometime which breaks
|
||||
unmarshalling code objects [hard to reproduce, have added a trap to
|
||||
marshal.c to catch it]
|
||||
|
||||
(-) destroying all modules may destroy __builtin__ (or other modules)
|
||||
while destructors of other modules may still need it [hard to fix --
|
||||
could maintain a list of all modules in order of importation so we can
|
||||
destroy them in reverse order??? really hopeless -- would have to
|
||||
destroy objects in a module in reverse order too...]
|
||||
|
||||
(-) doneimport() should be called *before* the Py_AtExit code is
|
||||
called [problem: what if other threads are still active?]
|
||||
|
||||
Known portability problems
|
||||
--------------------------
|
||||
|
||||
(-) arraymodule doesn't compile under Ultrix (FPROTO macro)
|
||||
|
||||
(-) makesetup assumes CCC is the C++ compiler -- not portable
|
||||
|
||||
(-) "make depend" assumes mkdep exists -- not portable
|
||||
|
||||
(-) regen calls h2py which isn't defined by default
|
||||
|
||||
(-) HP doesn't compile out of the box (needs LIBS=-ldld or
|
||||
LIBS=/usr/lib/libdld.sl) [hard to test without a HP machine handy]
|
||||

||||
--------------------------------------
|
||||
|
||||
(*) extraneous fclose() in run_script() in pythonrun.c for .pyc file

||||
(*) posix.utime gives problems on problems on platforms where struct
|
||||
utime members are bitfields
|
||||
|
||||
(*) leak in regex module.c:reg_dealloc() -- should free compiled pattern
|
||||
|

(*) many uses of macros from <ctype.h> fail with signed characters
|

|
||||
(*) compilation on NeXT requires manual editing of the Makefile
|

|
||||
create it
|
||||
|
||||
(*) a file with unmatched triple quotes causes a loop in the scanner
|
||||
|
||||
(*) [X]DECREF can cause the interpreter to be called recursively (for
|
||||
__del__ disciplines) -- so list and dict implementation calls doing
|
||||
DECREF can cause recursive calls to methods of the object being
|
||||
modified. Other files too.
|
||||
|
||||
(*) if __getattr__ or __repr__ prints something, calling repr(x) from
|
||||

|
||||
|
||||
(*) pow(int, int, long) does wrong series of DECREF() calls.

|
||||
(*) flushline() may clear the exception condition so shouldn't be

called before print_error()
|
||||
|
||||

|

some calls aren't thread safe)
|
||||
|
||||

|
||||
(*) threadmodule.c leaks 'res' in t_bootstrap
|

|
||||
(*) errors.c shouldn't declare strerror() on NT
|
||||
|
||||
(*) DECREF can cause the interpreter to be called recursively (for
|
||||
__del__ disciplines) -- so list and dict implementation calls doing
|
||||
DECREF can cause recursive calls to methods of the object being
|
||||
modified. Other files too. (Only partially fixed.)
|
||||
|
||||
(*) tkinter dereferences NULL if timer callback raises an exception

|
||||
|
||||
(*) '%s' % a, where a is a class instance, fails
|
||||
|
||||
(*) "make test" won't find freshly built dynamically loaded modules --
|
||||
should add ./Modules to TESTPATH
|

|
||||
(*) lshift calls __rshift__ instead of __rlshift__
|
||||
|
||||
(*) memory leak in creation of sys.builtin_module_names
|
||||
|
||||
(*) Bugs in instance_dealloc(): (a) memory leak for exception
|
||||
type+value; (2) should save+restore traceback as well
|
||||
|
||||
(*) modsupport.c(vmkvalue): on systems where va_list is an array, the
|
||||
calls to do_mkvalue and do_mktuple don't want an "&" before va.

BUGS found in 1.1 and fixed in 1.1.1

||||
------------------------------------
|
||||
|
||||
(*) printing name of lambda in traceback dereferences NULL
|
||||

|
||||
|
||||
(*) newgetargs() dumps core in compat mode when NULL is passed in but
|
||||
max is >0
|
||||
|
||||
(*) pow() should be declared varargs since it uses newgetargs
|
||||
|
||||
(*) newmodule.c doesn't compile on SunOS 4.1.3 due to non-K&R backslashes
|
||||
|
||||
(*) some typos in tut.tex
|
||||
|
||||
(*) test for broken static forward is not strong enough
|
||||
|
||||
(*) Doc/Makefile assumes . is in $PATH in call to whichlibs
|
||||
|
||||
(*) math module misses hypot() function
|
||||
|
||||
(*) structmember.h should include stddef.h (for offsetof macro)

======================================================================
|
||||
BUGS found in 1.0.3 and fixed in 1.1
|
||||
------------------------------------
|
||||
|
||||
(*) 2 specific leaks: 1 PYTHONPATH; 2 reading code from .pyc
|
||||
|
||||
(*) If class C doesn't define __cmp__, cmp(a,b) will return -2 and
|
||||
[a,b].sort() will fail
|
||||
|
||||
(*) Syntax errors are reported in a silly way if multi-line tokens are
|
||||
involved.
|
||||
|
||||
(*) SyntaxError exception for compile('...') are reported wrongly
|
||||
(lineno is always zero and offset is offset into the whole string).
|
||||
|
||||
(*) freeze script needs major rewrite to cope with multiple extensions
|
||||
(Jack seems to have fixed it now -- where is it?)
|
||||
|
||||
(*) unwanted entries in stack trace if err_clear() clears an error
|
||||
that also set a stack trace
|
||||
|
||||
(*) i, x[i] = a, b assigns b to x[a] rather than to x[i] as expected
|
||||
(documented with a warning in ref6.tex!)
|
||||
|
||||
(*) etags no longer supports -t flag
|
||||
|
||||
(*) compile.c:com_argdefs() references unalloc'ed memory for def
|
||||
f(a=1,): ...
|
||||
|
||||
(*) If you have a python binary in your path like
|
||||
/ufs/guido/bin/sgi/python then the default prefix option computed by
|
||||
the configure script is bogus!
|
||||
|
||||
(*) Make rule for making lib*.a should remove the lib*.a file first.
|
||||
|
||||
(*) vars() error message is wrong (copied from dir() obviously).
|
||||
|
||||
(*) socket.gethostname() is undocumented.
|
||||
|
||||
(*) rfc822.py: getfirst* dies when multiple headers occur
|
||||
|
||||
(*) urllib caching is wrong (should use date from Expires header)
|
||||
|
||||
(*) On a related matter: regexpr.c still has two malloc()s the results
|
||||
of which are not tested for being NULL (lines 1253 and 1530). There
|
||||
are also some in rgbimagemodule.c. Am I overlooking something or is
|
||||
this a crasher?
|
||||
|
||||
(*) strop.rindex('abc', '') returns 0 instead of 3
|
||||
|
||||
(*) sunaudiodevmodule.o is too long!
|
||||
|
||||
(*) toplevel README needs new text on PC and Mac builds
|
||||
|
||||
(*) long(0x80000000) has wrong value!

||||

|
||||
-------------------------------------
|
||||
|
||||
(?) compiler warnings about argument type of uname() on ULTRIX
|
||||
machines (don't know what to do about it) [could be fixed by fix for
|
||||
bitfields in struct uname]
|
||||
|
||||
(?) syntax error for interactive input prints garbage instead of last
|
||||
source line on some systems (e.g. AIX) (impossible to test/reproduce)
|
||||
[I think I've found this one -- a missing INCREF in print_error]
|
||||
|
||||
(?) (maybe) a bad .pyc file (with old magic number) causes the .py
|
||||
file to be ignored [should be fixed by rewrite of import.c]
|
||||
|
||||
(?) Sunos4.0.2 / 386 configure bugs:
|
||||
- timelocal instead of mktime
|
||||
- unistd.h doesn't declare some functions

||||
|
||||
(*) nasty bug in string formatting (see test_types.py, search for %)
|
||||
|
||||
(*) if a triple-quoted string ends in a quote followed by a newline
|
||||
(followed immediately by the terminating 3 quotes) then a syntax error
|
||||
or system error ensues
|
||||
|
||||
(*) bug in socket.listen: clipping backlog to >= 1 doesn't work
|
||||
|
||||
(*) two bogus XDEL's in Modules/regexmodule.reg_dealloc()
|

|
||||
because of '_'
|
||||
|
||||
(*) tokenizer/tok_nextc() runs into infinite loop when file does not
|
||||
end in linefeed
|
||||
|
||||
(*) Sunos4.0.2 / 386 configure bugs:
|
||||
(*) - use size_t at some places without including sys/types.h
|
||||
(*) - missing clock_t
|
||||
(*) - uses SEEK_SET in some places that don't include unistd.h

|
||||
(?) threads are slow on Solaris 2
|
||||
(so what?)
|

|
||||
(?) min() on PC version generates wrong result (i.e. same as max())
|
||||
[this happens on SoftPC -- don't know about other systems]
|
||||
(can't find the reason -- may be SoftPC bug)
|
||||
|
||||
(*) flp.py cache bug: if the cache only contains one form, asking for
|
||||
all forms returns only the cached form
|
||||
|
