cpython / BUGS

Sorry, this list does not claim completeness.  If I fixed a bug
immediately upon receiving the first complaint I usually did not
nother to make an entry in this file, unless it was a serious bug
(core dump or infinite loop).

==> Status indicators: (-) not fixed; (*) fixed; (?) don't know what to do.

BUGS found in 1.0.3 and not yet fixed

(-) print_error raises and then masks an error if softspace is not
    defined (can't reproduce this one?)

(*) Syntax errors are reported in a silly way if multi-line tokens are

(*) 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?)

(*) various memory leaks (see purify report from anthony.baxter@aaii.oz.au)
(several leaks fixed anyway :-)

BUGS found in 1.0.3 and fixed in 1.1

(*) 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!

Bugs found in 1.0.2 and not yet fixed

(?) compiler warnings about argument type of uname() on ULTRIX
machines (don't know what to do about it)

(?) 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

(?) Sunos4.0.2 / 386 configure bugs:
	- timelocal instead of mktime
	- unistd.h doesn't declare some functions
(don't know what to do about this)

Bugs found in 1.0.2 and fixed in 1.0.3

(*) 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()

(*) Parser/myreadline.my_fgets: #endif EINTR misplaced

(*) new IP address for ftp.cwi.nl !!!

(*) typing vars() to interactive prompt runs into infinite loop
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

Bugs found in 1.0.1 and not yet fixed

(?) 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.
(don't know what to do about this)

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

(*) threads cause myreadline.c's readline() to think it sees an EOF.
(I *think* I've fixed this, by testing for EINTR)

(?) 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

Bugs found in 1.0.1 and fixed in 1.0.2

(*) core dump when parser.parsefile() called

(*) man page contains a mess before -d option

(*) threads don't work on IRIX 4

(*) wrong cast of svideo_getattr in svmodule.c

(*) bad return value in runpython.c's run_tty_1()

(*) creating dict of 100,000 objects gets MemoryError or dumps core

(*) freeze script doesn't work

BUGS found in 1.0.0 and not yet fixed

(?) On NeXT, need to define _POSIX_SOURCE.

(?) there appears to be something wrong with gcc and -ldl on some
SunOS 4.1.3 systems

(?) jredfords reports core dump with float literals

BUGS found in 1.0.0 and fixed in 1.0.1

(*) On SGI IRIX 4 using cc, compilation errors in md5module.c.

(*) In cdmodule.c, getattr initialized with (destructor)!

(*) Lib/tzparse.py runs test() on import

(*) Lib/filewin.py belongs in Lib/stdwin

(*) lib and man install targets don't use $(srcdir)

(*) Modules/rgbimgmodule.c: exception name contains comma instead of dot

(*) The FAQ still references misc/EXTENDING and misc/DYNLOAD etc

(*) The FAQ still describes how to work around a problem in 0.9.9 exec()

(*) Lib/aifc.py, returns float rate, should be int

(*) Lib/sunau.py, incorrectly cumputes byte count from frame rate

(*) README should mention possibility of passing OPT=-g to make

(*) dynamic loading on sunos 4.1.3 must call dlopen(..., 1)

(*) use of <varargs.h> vs. <stdarg.h> should depend on

(*) Doc/README refers to Misc/FTP which in fact does not exist any more

(*) filter(None, 'abcdefg') dumps core

(*) once you interrupt time.sleep(), there is no interrupt handler!
