Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: Joseph Heled (pepster) Assigned to: Nobody/Anonymous (nobody) Summary: pdb 'next' does not skip list comprehension Initial Comment: pdb next command forces you to step over each list element. This seem to be a reincarnation of this old bug. https://sourceforge.net/tracker/?func=detail&atid=105470&aid=523995&group_id=5470 Version: Python 2.4.1 (#2, Mar 30 2005, 21:51:10) [GCC 3.3.5 (Debian 1:3.3.5-8ubuntu2)] on linux2 ---------------------------------------------------------------------- Comment By: Ilya Sandler (isandler) Date: 2005-07-30 17:33 Message: Logged In: YES user_id=971153 I changed bdb.py to print the kind of event it receives as well as as line numbers and here is a session which illustrates the bug... bagira:~/python/dist/src/bug-next1248119> cat t #../python y=[1,2,3,4] x=[ i+1 for i in y] print x bagira:~/python/dist/src/bug-next1248119> ../python -m pdb t event: call; line 1, file <string> event: line; line 1, file <string> event: call; line 2, file t event: line; line 2, file t > /home/ilya/python/dist/src/bug-next1248119/t(2)?() -> y=[1,2,3,4] (Pdb) n event: line; line 3, file t > /home/ilya/python/dist/src/bug-next1248119/t(3)?() -> x=[ i+1 for i in y] (Pdb) n event: line; line 3, file t > /home/ilya/python/dist/src/bug-next1248119/t(3)?() -> x=[ i+1 for i in y] (Pdb) n event: line; line 3, file t > /home/ilya/python/dist/src/bug-next1248119/t(3)?() -> x=[ i+1 for i in y] (Pdb) event: line; line 3, file t > /home/ilya/python/dist/src/bug-next1248119/t(3)?() -> x=[ i+1 for i in y] So it appears that the interpreter generates "line" events for every iteration of the loop.. Would this be a bug in the interpreter (and not in pdb/bdb)? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1248119&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
