-                             CVS port to VMS
-
-DISCLAIMER: This port must be considered experimental.  Although
-previous versions have been in use at one large site since about
-October, 1995, and the port is believed to be quite usable, various
-VMS-specific quirks are known and the port cannot be considered as
-mature as the ports to, say, Windows NT or unix.  As always, future
-progress of this port will depend on volunteer and customer interest.
-
-This port is of the CVS client only.  Or in other words, the port
-implements the full set of CVS commands, but cannot access
-repositories located on the local machine.  The repository must live
-on another machine (a Unix box) which runs a complete port of CVS.
-
-Most (all?) work to date has been done on OpenVMS/AXP 6.2.  Other VMS
-variants might work too.
-
-You will also need GNU patch installed on your system.  Here's a list
-of ftp servers which have VMS GNU resources, taken from
-
-    ftp://prep.ai.mit.edu/pub/gnu/vms.README
-
-    mvb.saic.com
-    wuarchive.wustl.edu
-    ftp.wku.edu
-    ftp.spc.edu
-    ftp.stacken.kth.se
-
-Please send bug reports to bug-cvs@prep.ai.mit.edu.
-
-As of CVS 1.5.something, this port passed most of the tests in
-[.src]sanity.sh.  I say "most" because some tests to not apply to the
-CVS client.  The tests were run by hand because the VMS POSIX shell
-was incapable of running the script.  The tests that sanity.sh
-provides are not conclusive but at least provides some assurance that
-the client is usable.
-
-To compile, you will need DEC C (CC), DEC UCX, and of course DCL
-installed on your machine.  Just type "@build" in the top level
-directory.  This will build the sources in each subdirectory, and link
-the executable [.src]cvs.exe
-
-Copy the executable to an appropriate directory, and define the symbol "CVS"
-in a .COM file which everyone running CVS will need to run.  Here's an example
-of what needs to be done.
-
-$ CVS :== $YOUR_DEVICE:[YOUR.DIRECTORY.CVS]CVS.EXE
-
-Accessing a remote repository can happen in several ways.
-
-1. pserver
-2. rsh - privileged (default)
-3. rsh - unprivileged (on VMS side)
-
-Here's how to do each of the above:
-
--------------------------------------------------------------------------------
-1.  pserver.  This is the preferred way.  It works just as it is
-documented in the CVS manual (see the README file in the CVS
-distribution for more information on the manual).
-
--------------------------------------------------------------------------------
-2. Using CVS internal rsh support (privileged)
-
-VMS's RSH is unusable for CVS's purposes (that is, the one in UCX.
-Don't know about Multinet).  However, there is code within CVS to
-emulate RSH for purposes of contacting a CVS server "in the usual way"
-via rshd.  Unfortunately, this requires the VMS CVS client to be
-installed with OPER privilege, by your system administrator.
-
-RSH uses privileged ports and trusted software/hosts to determine
-which user on the client side is trying to connect.  Part of this
-security is due to the fact that on VMS or UNIX, a non privileged
-process is not permitted to bind a socket to a privileged port.
-
-If rshd receives a connection on a non-privileged port, the connection is
-immediately aborted.  Only connections arriving from a privileged port will
-be authenticated and served.  The CVS client will therefore need privileges
-under VMS to produce such a connection.
-
-*** Please note that no careful examination has been done of the security
-    implications of installing CVS with the OPER privilege.  If some hole
-    exists, then by doing so, you will enable users who are already on
-    your system to gain unauthorized privileges ***
-
--------------------------------------------------------------------------------
-3. Using CVS internal rsh support (non-privileged)
-
-There is a workaround, but this is one case where I think the cure is worse
-than the disease.  If you patch an rshd to not care that the RSH originating
-port is "non-privileged", the CVS VMS client will allow you to define the
-logical CVS_RCMD_PORT to the port number where this patched rshd will be
-listening.  I leave the talk of patching rshd to the gentle reader and his/her
-friendly system administrator.
-
-If I put an entry in my /etc/services file:
-
-cvs_rcmd            4381/tcp        cvs_rcmd
-
-And add a line to /etc/inetd.conf, then restart inetd via "kill -1"
-
-cvs_rcmd  stream  tcp  nowait root /usr/sbin/tcpd  /usr/local/sbin/cvs_rcmd
-
-On the VMS side, you will have to do this:
-
-$ define CVS_RCMD_PORT 4381
-
-Then run CVS in the "usual way".
-
-Note that the patched rshd will need to be invoked via inetd as root, so it can
-authenticate and _become_ the intended user, the same as the regular rshd.
-
-***Please note that you will be installing a security hole by doing this.***
-
-Please also note that this security hole is no larger than allowing a
-Macintosh, PC (OS/2, NT, etc.) to have it's hostname in any .rhosts file,
-as any user can create a privileged socket without authentication, under these
-environments.  In fact, existing ports of CVS to these environment use this
-to their advantage.
-
--------------------------------------------------------------------------------
-Wildcard expansion is not yet implemented (i.e. CVS COMMIT *.c won't
-work.)  I think that expand_wild should be calling lib$findfile
-(util.c in gzip is said to provide an example), but noone has gotten
-around to implementing this.
-
-Log messages must be entered on the command line using -m or -F.  You
-can use -e or define the logical EDITOR to cause CVS to try other
-editors (TPU.EXE or any other editor which wants DCL command parsing
-will not work) if you want to test what's available on your system.  I
-haven't tested this, but if you install vi or emacs, chances are it
-will probably work.  Just make sure the .EXE files are in a directory
-listed in VAXC$PATH (is this a typo for DCL$PATH?  Also, will a
-logical name work?).  If someone gets around to implementing it, we
-should probably be using the callable editors (e.g. TPU$TPU), although
-of course we also need interface(s) which are not locked into any
-particular editors.
-
-----------------------------------------
-
-Notes regarding compiling on VAX/VMS 6.2 (not Alpha) (These are items
-which hopefully will have cleaner solutions in the future, but here is
-how to get around them for now):
-
-* Need to compile lib/getdate.c with vaxc instead of decc to avoid a
-compiler bugcheck.  Therefore one must add SYS$LIBRARY:VAXCRTL/LIBRARY
-to the link.
-
-* In src/ignore.c, change lstat to stat.  In vms/filesubr.c, change
-"#ifdef S_ISLNK" to "#if 0".
-
-* Ignore the warnings in vms/vmsmunch.c; the system include file
-declares something as an int when it should be void *.  Not *our*
-fault!

-The enclosed two messages describe a bug in GNU diff 2.6 and 2.7 which
-may cause CVS to perform an erroneous merge.  You may wish to use GNU
-diff 2.5 or apply the patch supplied by Loren James Rittle below.  It
-would be nice to add this to the CVS testsuite, but I haven't done so

-Subject: diffutils 2.7 -- diff3 merge bug
-Date: Tue, 29 Oct 96 17:02:54 CST
-
-I believe a change first introduced in GNU diff 2.6 causes diff3 sometimes
-to produce incorrect merges.
-
-Since this is a not a bug in CVS itself but can cause commits to CVS
-repositories to be incorrect, am warning info-cvs@prep.ai.mit.edu as
-well as reporting the bug to bug-gnu-utils@prep.ai.mit.edu.
-
-I am including a simple test case as well as some sample outputs from
-different versions of `diff' and `diff3' in the enclosed shar archive.
-In addition, the file DESCRIPTION in that archive describes the problem
-more fully.
-
-If anyone has any advice for how to fix or to work around this bug, I would
-appreciate it.  Using diff 2.5 seems like the most immediately obvious
-solution, but I don't know if it will introduce other problems.
-I do not understand the algorithms used by GNU diff well enough to suggest
-any patches.
-
-Unshar and enjoy.  ;-)

-Subject: Re: diffutils 2.7 -- diff3 merge bug
-
-Noah,
-
-I have seen the problem you discuss in your e-mail, however I fail to
-see how this situation is as critical as might be implied since it can
-never arise without at least some user involvement (an update that
-caused a merge is never automatically followed by a commit --- the
-user has a chance to inspect the merged file).  However, I will agree
-that I don't always look very closely at non-conflicted merges before
-checking them back in.
-
-You didn't give the exact CVS commands used to create a lossage,
-but I added the following to your Makefile, to help me see the problem
-in a CVS usage context:
-
-t-older: testcase-older
-	cp testcase-older t-older
-
-t-yours: testcase-yours
-	cp testcase-yours t-yours
-
-t-mine: testcase-mine
-	cp testcase-mine t-mine
-
-# Assume cvs-1.9
-cvs-test: t-older t-yours t-mine
-	rm -rf /tmp/cvs-test-root x x2
-	cvs -d /tmp/cvs-test-root init
-	mkdir x
-	cp t-older x/testcase
-	cd x; cvs -d /tmp/cvs-test-root import -m '' x X X1
-	rm -rf x
-	cvs -d /tmp/cvs-test-root co x
-	cvs -d /tmp/cvs-test-root co -d x2 x
-	cp t-yours x/testcase
-	cp t-mine x2/testcase
-	cd x; cvs ci -m ''
-	-cd x2; cvs ci -m ''
-	cd x2; cvs update
-	cat x2/testcase # at this point, user may commit blindly
-
-It looks like whomever added shift_boundaries() in analyze.c, which
-seems to be the source of the diff3 induced mischief, already provided
-a means to disable the boundary shifting optimization (at least with
-a recompile).
-
-Here is the patch I applied to diff to disable this (currently)
-overaggressive optimization:
-
-[ rittle@supra ]; diff -c analyze.c-old analyze.c    
-*** analyze.c-old       Wed Oct 30 14:10:27 1996
---- analyze.c   Wed Oct 30 13:48:57 1996
-***************
-*** 616,622 ****
-     but usually it is cleaner to consider the following identical line
-     to be the "change".  */
-  
-! int inhibit;
-  
-  static void
-  shift_boundaries (filevec)

-  
-! int inhibit = 1;
-

-
-Now, diff-2.7 with the above patch produces:
-
-[ rittle@supra ]; make diff-mine-yours 'DIFF=/usr/src/diffutils-2.7/diff'

-<   public Button (int x, int y, int width, int height)
-<   {

-
-A better solution might be to disable the boundary shifting code
-unless explicitly turned on via command line argument.  That way
-programs, like diff3, expecting unoptimized diff regions will work
-correctly, yet users can get smaller diffs, if desired.  The problem
-is that diff3 doesn't properly track changes once they have been
-optimized.
-
-BTW, I never did like the look of the `optimized diff regions', so I
-consider this a good change for other reasons... :-)
-
-Enjoy!

----
-Old notes...
-
-* All sizing limits are gone.  The rest of these items were incidental
-  in that effort.
-
-* login name from history was duplicated.  taught existing routine to
-  cache and use that instead.  Also add routines to cache uid, pid,
-  etc.
-
-* ign strings were never freed.  Now they are.
-
-* there was a printf("... %s ...", cp) vs *cp bug in history.c.  Now
-  fixed.
-
-* The environment variables TMPDIR, HOME, and LOGNAME were not
-  honored.  Now they are.
-
-* extra line inserted by do_editor() is gone.  Then obviated.  Editor
-  is now called exactly once per checkin.
-
-* revised editor behaviour.  Never use /dev/tty.  If the editor
-  session fails, we haven't yet done anything.  Therefor the user can
-  safely rerun cvs and we should just fail.  Also use the editor for
-  initial log messages on added files.  Also omit the confirmation
-  when adding directories.  Adding directories will require an
-  explicit "commit" step soon.  Make it possible to prevent null login
-  messages using #define REQUIRE_LOG_MESSAGES
-
-* prototypes for all callbacks.
-
-* all callbacks get ref pointers.
-
-* do_recursion/start_recursion now use recusion_frame's rather than a
-  list of a lot of pointers and global variables.
-
-* corrected types on status_dirproc().
-
-* CONFIRM_DIRECTORY_ADDS
-
-* re_comp was innappropriate in a few places.  I've eliminated it.
-
-* FORCE_MESSAGE_ON_ADD
-
-* So I built a regression test.  Let's call it a sanity check to be
-  less ambitious.  It exposed that cvs is difficult to call from
-  scripts.

-WHAT THE "DEATH SUPPORT" FEATURES DO:
-
-(Some of the death support stuff is documented in the main manual, but
-this file is for stuff which noone has gotten around to adding to the
-main manual yet).
-
-CVS with death support can record when a file is active, or alive, and
-when it is removed, or dead.  With this facility you can record the
-history of a file, including the fact that at some point in its life
-the file was removed and then later added.
-
-Files can now be added or removed in a branch and later merged
-into the trunk.
-
-	cvs update -A
-	touch a b c
-	cvs add a b c ; cvs ci -m "added" a b c
-	cvs tag -b branchtag
-	cvs update -r branchtag
-	touch d ; cvs add d
-	rm a ; cvs rm a
-	cvs ci -m "added d, removed a"
-	cvs update -A
-	cvs update -jbranchtag
-
-Added and removed files may also be merged between branches.
-
-Files removed in the trunk may be merged into branches.
-
-Files added on the trunk are a special case.  They cannot be merged
-into a branch.  Instead, simply branch the file by hand.
