PR: bin/176886 2011-08-14T13:37:38Z Jilles Tjoelker jilles@FreeBSD.org 2011-08-14T13:37:38Z urn:sha1:54d34ff63deb6b929444de83db4c9fa96e7ba6e5 If tail notices that a file it is following no longer exists (because stat() fails), it will output any final lines and then close the file. If the read operation also causes an error, such as when the filesystem is forcefully unmounted, it closes the file as well, leading to fclose(NULL) and a segmentation fault.

Fix this, so we can bump WARNS as well. 2009-11-02T12:35:38Z Christian Brueffer brueffer@FreeBSD.org 2009-11-02T12:35:38Z urn:sha1:cf6c5eebe7a6f0f1e8b75d249a54989c5fa3bcdc Submitted by: Ulrich Spoerlein 2009-06-05T09:08:53Z Brian Somers brian@FreeBSD.org 2009-06-05T09:08:53Z urn:sha1:22da50cfc88081e487465042b96f969349ecb6c5 trying to open files rather than giving up when it encounters an error. ENOENT errors are not reported. As a result, files that are moved away then recreated are not at risk of being 'lost' to tail. Files that are recreated and temporarily have unreadable permissions will be shown when they are fixed. This behaviour is consistent with the GNU version of tail but without the verbiage that goes with the GNU version. This change also fixes error messages accompanying -f and -F. They no longer report problems with (null)!
