I have committed a patch that make sure that bash is used to run the testsuite. It fixes all the tests, except tst-cancel7.out and tst-cancelx7.out. Those two failures are due to the behavior of dash versus bash. The test tries to test that system() is cancellable. system() invokes /bin/sh (and this is hard-coded, not changeable via any environment variable). When doing /bin/bash -c "/bin/echo foo", bash is clever enough to invoke /bin/echo with execve() without forking. When system() kills the subprocess, it kills the intended subprocess. But dash forks a further subprocess and waits, so system() just kills dash, not dash's subprocess. I don't know what is the best way (if there is a way) to fix this problem with dash. -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
