Not yet bsd diff and bsd diff3 are very far from mature, however the sdiff(1)
part has landed as I have finished it. I still have plans for other diff
components.

So no affect.

Also no effect. Is our diff3 still the gpl'd one, or has bsd-diff
finally grown that functionality?

Works for me. I didn't even know this existed. From mall evidence I
can find, it looks like I stopped using RCS entirely in about 1999,
and that's 5 years after I moved to CVS for most things.

This is in line with what we've told people in the past. If I want to
play rogue, I have to install a port...

If people want it, they can make it a port...

Works for me.

+1 to removing GNU RCS.

FWIW;

I did bring OpenRCS to the vendor area:

https://svnweb.freebsd.org/base/vendor/OpenBSD/dist/usr.bin/rcs/

And I have a patch so that it builds on FreeBSD:

https://people.freebsd.org/~pfg/patches/openrcs.diff

It is known to NOT pass the GNU RCS testsuite and I lost interest in it.

Err... yeah. :-/  I was using RCS before it was GPLed :-(

Right; I'm one of those (folks who use RCS for local config files and
the like).  As well as Web pages, xfig files

Hmm  If there were a FreeBSD port for OpenRCS, I'd be interested in
poking at it  I'm not even at all sure that I need "100%
compatib[ility]" with any version of a GPLed RCS.  (Indeed; I may not
*want* such compatibility)

OK; warning received. :-}  Thanks

I forgot to say freebsd-update uses merge(1) and which I will replaced with
diff3(1).

[RFC] remove GNU rcs from FreeBSD 12

[Baptiste Daroussin]

hi,

For long we are planning to remove GNU rcs from base, after a failed attempt
before FreeBSD 10.0. Let see where we are to be able to remove it from FreeBSD
12.

GNU rcs is a GPLv2 software with newer version being GPLv3 preventing any
updates/fixes.

From previous discussions there were issues that has been raised in previous
attempts:
- ident(1) is still useful given we still have Keywords in our sources. It has
  been replaced by a BSD Licensed version (enhanced to improve compatibility
  with Subversion Keyword) for FreeBSD 11. So that tool will remain in base
  after removal of GNU rcs.
- etc-update uses merge(1) from GNU rcs, this has been changed in head to use
  diff3 instead.
- rc.subr allows to use rcs for the backup file functionality. This
  functionality is off by default as such I plan to make a warning if rcs is not
  installed and recommand to install rcs from base (or if noone claim using the
  feature I will just remove the functionality and only keep the default
  behaviour aka keep one backup copy).
- people uses rcs to handle configuration files in /etc for example. for those
  multiple compatible alternatives are available in ports:
  * rcs57: a copy of the latest version of GNU rcs in base before removal
(GPLv2)
  * rcs: latest GNU rcs version (GPLv3)

I haven't gone the direction of importing OpenRCS (BSD licensed version from
OpenBSD) as it needs way more work to be 100% compatible with latest version of
GNU rcs.

How to proceed:
- First turn off GNU rcs by default for a couple of month.
- Totally remove GNU rcs if no blockers has been raised.

Best regards,
Bapt
