lukem 8bfad4ad7a Use sleep(1) instead of usleep(1000000) to sleep for a second, since
usleep() doesn't support an argument >= 1000000.
Problem noted & fix provided in [bin/20644] from Dave Huang.

jdolecek 64275c4aaf use kqueue to watch the file if possible
from FreeBSD via Luke Mewburn

this specifically does NOT include FreeBSD rev. 1.28 change; it's
my understanding -F is specifically meant to only detect removal
of the tailed file, not to watch for intermediate path changes

explorer a3c923dc72 make tail -f and tail -10000 work on files > those which can be mmap()ed whole. tail -r will still not function on large files. 2001-11-21 06:47:07 +00:00
cgd b02d81404c avoid repeated error messages by making bytes(), lines() and rlines() return
meaningful values, which can then be checked to avoid another error message.

cjs 59a47ce7be Remove tracking of file size by how many characters were output.
This succumbs to a race condition where data are written to the
file while the sleep is occurring. If a stat is done immediately
after, lastsize is updated but the file pointer wasn't pointing at
the end of the file, so the number of bytes between the current
pointer and the end of the file is added to the lastsize when
lastsize already points to the end of the file.

ghudson bd8bd7340f Don't rely on select() not to modify the timeval argument. Also,
simplify the code by passing in NULL rather than an empty fd_set to
indicate no file descriptors.
