Specifically, import the diff from commit e745bd4c10ab to commit 83563783cc2 in https://github.com/vixie/cron.git My sole motivation is changing to the common MIT license. The old license, especially the "buildable source" clause, is unfriendly for commercial users of this code. Simply changing the license without importing [most of] the code accompanying that license seemed legally dubious. The most regrettable change is losing Paul's uucp path. I partially atone for this loss by restoring the upstream $Id$ tags, since $FreeBSD$ is no longer useful. This is [intended to be] a complete list of the functional changes in this commit. Some changes were made so that we could consider vixie cron to be our upstream and reduce our diffs against it, while others were simply a good idea. - main() - use putenv instead of setenv for PATH - open_pidfile no longer needs snprintf to build pidfile - crontab main() - abort() on impossible errors - check for truncation when building strings with snprintf - getdtablesize() -> sysconf(_SC_OPEN_MAX) These changes were not taken from upstream's 4.0 diff because they [could] actually change behavior. Some of them might be beneficial, but should be taken separately. - config.h - sendmail args: remove -oi and add -or0s - call setlocale(LC_ALL, "") at the top of main() - acquire_daemonlock - we already use pidfile - cast getpid(), uid_t, and gid_t to long for printf - remove unnecessary braces - I consider them beneficial - BSDi support - glue_strings() - use snprintf(), as we often already did MFC after: on demand Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D40260

Read the comments at the top of the Makefile, then edit the area marked
|
|
'configurable stuff'.
|
|
|
|
Edit config.h. The stuff I expect you to change is down a bit from the
|
|
top of the file, but it's clearly marked. Also look at pathnames.h.
|
|
|
|
You don't have to create the /var/cron or /var/cron/tabs directories, since
|
|
both the daemon and the `crontab' program will do this the first time they
|
|
run if they don't exist. You do need to have a /var, though -- just "mkdir
|
|
/var" if you don't have one, or you can "mkdir /usr/var; ln -s /usr/var /var"
|
|
if you expect your /var to have a lot of stuff in it.
|
|
|
|
You will also need /usr/local/etc and /usr/local/bin directories unless you
|
|
change the Makefile. These will have to be created by hand, but if you are
|
|
a long-time Usenet user you probably have them already. /usr/local/man is
|
|
where I keep my man pages, but I have the source for `man' and you probably
|
|
do not. Therefore you may have to put the man pages into /usr/man/manl,
|
|
which will be hard since there will be name collisions. (Note that the man
|
|
command was originally written by Bill Joy before he left Berkeley, and it
|
|
contains no AT&T code, so it is in UUNET's archive of freely-distributable
|
|
BSD code.)
|
|
|
|
LINUX note: /usr/include/paths.h on some linux systems shows _PATH_SENDMAIL
|
|
to be /usr/bin/sendmail even though sendmail is installed in /usr/lib.
|
|
you should check this out.
|
|
|
|
say:
|
|
make all
|
|
|
|
su and say:
|
|
make install
|
|
|
|
Note that if I can get you to "su and say" something just by asking, you have
|
|
a very serious security problem on your system and you should look into it.
|
|
|
|
Edit your /usr/lib/crontab file into little pieces -- see the CONVERSION file
|
|
for help on this.
|
|
|
|
Use the `crontab' command to install all the little pieces you just created.
|
|
Some examples (see below before trying any of these!)
|
|
|
|
crontab -u uucp -r /usr/lib/uucp/crontab.src
|
|
crontab -u news -r /usr/lib/news/crontab.src
|
|
crontab -u root -r /usr/adm/crontab.src
|
|
|
|
Notes on above examples: (1) the .src files are copied at the time the
|
|
command is issued; changing the source files later will have no effect until
|
|
they are reinstalled with another `crontab -r' command. (2) The crontab
|
|
command will affect the crontab of the person using the command unless `-u
|
|
USER' is given; `-u' only works for root. When using most `su' commands
|
|
under most BSD's, `crontab' will still think of you as yourself even though
|
|
you may think of yourself as root -- so use `-u' liberally. (3) the `-r'
|
|
option stands for `replace'; check the man page for crontab(1) for other
|
|
possibilities.
|
|
|
|
Kill your existing cron daemon -- do `ps aux' and look for /etc/cron.
|
|
|
|
Edit your /etc/rc or /etc/rc.local, looking for the line that starts up
|
|
/etc/cron. Comment it out and add a line to start the new cron daemon
|
|
-- usually /usr/local/etc/cron, unless you changed it in the Makefile.
|
|
|
|
Start up this cron daemon yourself as root. Just type /usr/local/etc/cron
|
|
(or whatever); no '&' is needed since the daemon forks itself and the
|
|
process you executed returns immediately.
|
|
|
|
ATT notes: for those people unfortunate enough to be stuck on a AT&T UNIX,
|
|
you will need the public-domain "libndir", found in the B News source and in
|
|
any comp.sources.unix archive. You will also need to hack the code some.
