Category: Extension Modules Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Richard B. Kreckel (richyk) Assigned to: Nobody/Anonymous (nobody) Summary: Calling tparm from extension lib fails in Python 2.5 Initial Comment: Attached is a little C++ module that fetches the terminal capability string for turning off all attributes and runs it through tparm(). (All this is done in a static Ctor of a class without init function, but never mind.) Compile with: g++ -c testlib.cc g++ testlib.o -o testlib.so -shared -Wl,-soname,testlib.so -lncurses On SuSE Linux 10.1 (and older), I get the expected behavior: Python 2.4.2 (#1, Oct 13 2006, 17:11:24) [GCC 4.1.0 (SUSE Linux)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import testlib Terminal is "xterm" Dump of sgr0: 1b 5b 30 6d Dump of instance: 1b 5b 30 6d Traceback (most recent call last): File "<stdin>", line 1, in ? ImportError: dynamic module does not define init function (inittestlib) >>> However, on SuSE Linux 10.2, tparm creates a NULL pointer: Python 2.5 (r25:51908, Jan 9 2007, 16:59:32) [GCC 4.1.2 20061115 (prerelease) (SUSE Linux)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import testlib Terminal is "xterm" Dump of sgr0: 1b 5b 30 6d Rats! tparm made a NULL pointer! Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dynamic module does not define init function (inittestlib) >>> Why, oh why? ---------------------------------------------------------------------- >Comment By: Richard B.

(I've not enough time and my company doesn't let me access your SVN.) ---------------------------------------------------------------------- Comment By: Neal Norwitz (nnorwitz) Date: 2007-02-25 23:16 Message: Logged In: YES user_id=33168 Originator: NO Can you test with 2.5 from SVN and confirm your program works in the complete context? ---------------------------------------------------------------------- Comment By: Richard B. Kreckel (richyk) Date: 2007-02-22 13:25 Message: Logged In: YES user_id=1718463 Originator: YES The error message about the undefined init function is a red herring. The example is actually a stripped-down testcase from a much larger Boost.Python module, which of course does have an init function. The point here is the NULL pointer returned by tparm. ---------------------------------------------------------------------- Comment By: Martin v. Löwis (loewis) Date: 2007-02-14 22:24 Message: Logged In: YES user_id=21627 Originator: NO I fail to see the bug. The exception precisely describes the error in your code ImportError: dynamic module does not define init function (inittestlib) Why do you expect any meaningful behavior in the presence of this error? Your shared library isn't an extension module. If you think it is related to #1548092, please try out the subversion trunk, which has fixed this bug. ---------------------------------------------------------------------- Comment By: Richard B. Kreckel (richyk) Date: 2007-02-14 09:52 Message: Logged In: YES user_id=1718463 Originator: YES I suspect that this is a duplicate of Bug [1548092]. Note that, there it is asserted that tparm returns NULL on certain invalid strings. That does not seem to be true. It returns NULL for valid trivial strings, too. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1659171&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
