New submission from Xavier de Gaye <xdeg...@gmail.com>: When a breakpoint is set anywhere (in which case the global system's trace function is set), interrupting the debuggee causes Pdb to stop into its own code. See the following pdb session run with python on the current head of the default branch from the repo.
=== main.py ================================= import time def bar(): i = 1 while i: time.sleep(.100) bar() ================================================= $ python -m pdb main.py > /path_to/main.py(1)<module>() -> import time (Pdb) import sys; print(sys.version) 3.3.0a3+ (default:4e9680570be8, May 11 2012, 12:09:15) [GCC 4.3.2] (Pdb) break bar Breakpoint 1 at /path_to/main.py:2 (Pdb) continue > /path_to/main.py(3)bar() -> i = 1 (Pdb) continue ^C Program interrupted. (Use 'cont' to resume). --Call-- > /home/xavier/src/cpython/cpython-hg-default/Lib/bdb.py(212)set_trace() -> def set_trace(self, frame=None): (Pdb) where /home/xavier/src/cpython/cpython-hg-default/Lib/bdb.py(405)run() -> exec(cmd, globals, locals) <string>(1)<module>() /path_to/main.py(7)<module>() -> bar() /path_to/main.py(5)bar() -> time.sleep(.100) /home/xavier/src/cpython/cpython-hg-default/Lib/pdb.py(196)sigint_handler() -> self.set_trace(frame) > /home/xavier/src/cpython/cpython-hg-default/Lib/bdb.py(212)set_trace() -> def set_trace(self, frame=None): (Pdb) quit ================================================= The attached patch fixes the problem and includes a test case. This fix is the same as the one proposed at issue 14743 to fix another problem, except that the set_step call is moved at the end of the sigint_handler method for the sake of robustness. ---------- components: Library (Lib) files: pdb_default.patch keywords: patch messages: 160467 nosy: xdegaye priority: normal severity: normal status: open title: Pdb debugs itself after ^C and a breakpoint is set anywhere type: behavior versions: Python 3.2 Added file: http://bugs.python.org/file25547/pdb_default.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14788> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
