* Fix memory leaks during "tail -r" of an irregular fileAlan Somers2017-01-104-77/+309
| | | | | | | | | | | | | | | | | * Rewrite r_buf to use standard tail queues instead of a hand-rolled circular linked list. Free dynamic allocations when done. * Remove an optimization for the case where the file is a multiple of 128KB in size and there is a scarcity of memory. * Add ATF tests for "tail -r" and its variants.

| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | 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)! MFC after: 3 weeks Notes: svn path=/head/; revision=193488

* Better handle the -F case:Marcel Moolenaar2006-10-211-7/+5
| | | | | | | | | | | | | | | | | | | | o When stat(2) fails (i.e. the file has been moved) there's no new file with the same name yet, so keep showing the file that's open. This yields the same behaviour as -f, for which we don't stat(2). o When a new file with the same name has been created (i.e stat(2) succeeds but the inode or device numbers differ from the opened file), show any new lines in the opened file (i.e. the old or rotated file) before reopening the new file. These changes fix the observed behaviour that tail(1) doesn't show the very last lines of the rotated (log) files.

| | | | | | | | | | | | | | files is usually the first direct block pointer. Since FreeBSD does automatic block reallocation to reduce filesystem fragmentation, the file being tailed can be relocated to different blocks 'on-the-fly', making the check for st_rdev unreliable. The result of this bug is tail -F pseudo-randomnly thinking the file was rotated when it wasn't, and as a result, spews out the entire file trying to catch up.
