plus a couple of minor changes.. Some highlights of the new stuff that was not in the old version: - remote access support.. full checkout/commit/log/etc.. - much improved dead file support.. - speed improvements - better $CVSROOT handling - $Name$ support - support for a "cvsadmin" group to cut down rampant use of "cvs admin -o" - safer setuid/setgid support - many bugs fixed.. :-) - probably some new ones.. :-( - more that I cannot remember offhand..

(footnote 1)
|
|
AIX 4.1 systems fail to run "configure" due to bugs in their
|
|
"/bin/sh" implementation. You might want to try feeding the
|
|
configure script to "bash" ported to AIX 4.1. (about 1.4A2).
|
|
|
|
(footnote 2)
|
|
Some Irix 4.0 systems may core dump in malloc while running
|
|
CVS. We believe this is a bug in the Irix malloc. You can
|
|
workaround this bug by linking with "-lmalloc" if necessary.
|
|
(about 1.4A2).
|
|
|
|
(footnote 3)
|
|
There are some warnings about pointer casts which can safely be
|
|
ignored. (about 1.4.90).

-------------------------------------------------------------------------------
|
|
|
|
Installation under Unix:
|
|
|
|
1) Run "configure":
|
|
|
|
$ ./configure
|
|
|
|
You can specify an alternate destination to override the default with
|
|
the --prefix option:
|
|
|
|
$ ./configure --prefix=/usr/local/gnu
|
|
|
|
or some path that is more appropriate for your site. The default prefix
|
|
value is "/usr/local", with binaries in sub-directory "bin", manual
|
|
pages in sub-directory "man", and libraries in sub-directory "lib".
|
|
|
|
This release of CVS also requires RCS commands to be installed in
|
|
the user's PATH (or a path you have configured in src/options.h).
|
|
If you don't have RCS, you will need to get it from GNU as well. It
|
|
is best to get the version 5.7 (or later) version of RCS, available
|
|
from prep.ai.mit.edu in the file pub/gnu/rcs-5.7.tar.gz. It is best
|
|
(although not essential) to avoid RCS versions 5.6.[5-7] beta
|
|
because the rcsmerge therein defaults to -A instead of -E which
|
|
affects the way CVS handles conflicts (this is fixed in RCS 5.6.8
|
|
and RCS 5.7).
|
|
|
|
Along with RCS, you will want to run GNU diffutils. This will allow
|
|
revision control of files with binary data (a real nice feature).
|
|
You will need at least version 1.15 of GNU diff for this to work.
|
|
The current version of GNU diffutils is 2.7, and it is also
|
|
available from prep.ai.mit.edu in the file pub/gnu/diffutils-2.7.tar.gz.
|
|
|
|
WARNING: Be sure that you (have) configure(d) RCS to work correctly
|
|
with GNU diff to avoid other configuration problems.
|
|
|
|
Configure will attempt to discern the location of your most capable
|
|
version of diff, and tries to find the GNU Diffutils version first.
|
|
You can explicitly tell configure to use the diffutils that's
|
|
installed in the same place you intend to install CVS:
|
|
|
|
$ ./configure --with-diffutils
|
|
|
|
Or, if you've installed it somewhere else, you can give configure
|
|
the full pathname:
|
|
|
|
$ ./configure --with-diffutils=/usr/gnu/bin/diff
|
|
|
|
Configure will also try to find a version of grep that supports the
|
|
'-s' option, and tries to find the GNU Grep version first. You can
|
|
similarly tell it where to find GNU Grep:
|
|
|
|
$ ./configure --with-gnugrep
|
|
$ ./configure --with-gnugrep=/usr/gnu/bin/grep
|
|
|
|
If you are using the remote client, you will need a version of patch
|
|
which understands unidiffs (such as any recent version of GNU
|
|
patch). Configure does not yet check to see if you've got this, so
|
|
be careful!
|
|
|
|
NOTE: The configure program will cache the results of the previous
|
|
configure execution. If you need to re-run configure from scratch, you
|
|
may need to run "make distclean" first to remove the cached
|
|
configuration information.
|
|
|
|
Try './configure --help' for further information on its usage.
|
|
|
|
NOTE ON CVS's USE OF NDBM:
|
|
|
|
By default, CVS uses some built-in ndbm emulation code to allow
|
|
CVS to work in a heterogeneous environment. However, if you have
|
|
a very large modules database, this may not work well. You will
|
|
need to edit src/options.h to turn off the MY_NDBM #define and
|
|
re-run configure. If you do this, the following comments apply.
|
|
If not, you may safely skip these comments.
|
|
|
|
If you configure CVS to use the real ndbm(3) libraries and
|
|
you do not have them installed in a "normal" place, you will
|
|
probably want to get the GNU version of ndbm (gdbm) and install
|
|
that before running the CVS configure script. Be aware that the
|
|
GDBM 1.5 release does NOT install the <ndbm.h> header file included
|
|
with the release automatically. You may have to install it by hand.
|
|
|
|
If you configure CVS to use the ndbm(3) libraries, you cannot
|
|
compile CVS with GNU cc (gcc) on Sun-4 SPARC systems. However, gcc
|
|
2.0 may have fixed this limitation if -fpcc-struct-return is
|
|
defined. When using gcc on other systems to compile CVS, you *may*
|
|
need to specify the -fpcc-struct-return option to gcc (you will
|
|
*know* you have to if "cvs checkout" core dumps in some ndbm
|
|
function). You can do this as follows:
|
|
|
|
$ CC='gcc -fpcc-struct-return' ./configure
|
|
|
|
for sh, bash, and ksh users and:
|
|
|
|
% setenv CC 'gcc -fpcc-struct-return'
|
|
% ./configure
|
|
|
|
for csh and tcsh users.
|
|
|
|
END OF NOTE FOR NDBM GUNK.
|
|
|
|
2) Edit src/options.h. Appropriate things to look at may be the
|
|
invocation locations of programs like DIFF, GREP, RM, and SORT.
|
|
Also glance at the default values for the environment variables
|
|
that CVS uses, in particular, the RCSBIN variable, which holds the
|
|
path to where the RCS programs live on your system. The
|
|
likelihood is that you don't have to change anything here, except
|
|
perhaps adding the -a option to DIFF if you are using GNU diff.
|
|
|
|
3) Try to build it:
|
|
|
|
$ make
|
|
|
|
This will (hopefully) make the needed CVS binaries within the "src"
|
|
directory. If something fails for your system, using the "cvsbug"
|
|
script submit your "config.status" file together with your host
|
|
type, operating system and compiler information, make output, and
|
|
anything else you think will be helpful.
|
|
|
|
You may also wish to validate the correctness of the new binary by
|
|
running the regression tests:
|
|
|
|
$ make check
|
|
|
|
Note that if your /bin/sh doesn't support shell functions, you'll
|
|
have to try something like this, where "/bin/sh5" is replaced by the
|
|
pathname of a shell which handles normal shell functions:
|
|
|
|
$ make SHELL=/bin/sh5 check
|
|
|
|
WARNING: This test can take quite a while to run, esp. if your
|
|
disks are slow or over-loaded.
|
|
|
|
If you receive any un-expected output from the regression tests,
|
|
using the "cvsbug" script please submit your "config.status" file,
|
|
together with your host type, operating system and compiler
|
|
information, the contents of /tmp/cvs-sanity/check.log, and any
|
|
"make check" output.
|
|
|
|
4) Install the binaries/documentation:
|
|
|
|
$ make install
|
|
|
|
Depending on your installation's configuration, you may need to be
|
|
root to do this.
|
|
|
|
5) Take a look at the CVS documentation.
|
|
|
|
$ man cvs
|
|
|
|
and
|
|
|
|
$ info cvs
|
|
|
|
See what it can do for you, and if it fits your environment (or can
|
|
possibly be made to fit your environment). If things look good,
|
|
continue on...
|
|
|
|
6) Setup the master source repository. Choose a directory with ample disk
|
|
space available for source files. This is where the RCS ",v" files
|
|
will be stored. Note that this should be some shared directory for your
|
|
site. It should probably be auto-mounted, if you're running NFS.
|
|
|
|
Say you choose "/src/master" as the root of your source repository.
|
|
Run the "cvsinit" script to help you set it up. It will ask you to
|
|
enter the path to your CVSROOT area. You would enter /src/master in
|
|
this example.
|
|
|
|
$ ./cvsinit
|
|
|
|
The cvsinit script will setup a reasonable CVSROOT area to start with.
|
|
It is also valuable to folks who already have a CVSROOT area setup from
|
|
using earlier releases of CVS. It assumes that you have installed CVS
|
|
already (step 4) and that the RCS programs (co and ci) are in your
|
|
PATH. There are many ways to customize CVS for your site. Read the
|
|
cvs(5) manual page when you get the chance.
|
|
|
|
7) Have all users of the CVS system set the CVSROOT environment
|
|
variable appropriately to reflect the placement of your source
|
|
repository. If the above example is used, the following commands
|
|
can be placed in user's ~/.profile, ~/.bash_profile file; or in the
|
|
site-wide /etc/profile:
|
|
|
|
CVSROOT=/src/master; export CVSROOT
|
|
|
|
for sh/bash/ksh users, or place the following commands in the user's
|
|
~/.cshrc, ~/.login, or /etc/chsrc file:
|
|
|
|
setenv CVSROOT /src/master
|
|
|
|
for csh/tcsh users. If these environment variables are not already set
|
|
in your current shell, set them now (or source the login script you
|
|
just edited). You will need to have the CVSROOT environment variable
|
|
set to continue on to the next step.
|
|
|
|
8) It might be a good idea to jump right in and put the CVS distribution
|
|
directly under CVS control. From within the top-level directory of the
|
|
CVS distribution (the one that contains this README file) do the
|
|
following commands:
|
|
|
|
$ make distclean
|
|
$ cvs import -m 'CVS 1.6 distribution' cvs CVS CVS-1_6
|
|
|
|
9) Having done step 8, one should be able to checkout a fresh copy of the
|
|
CVS distribution and hack away at the sources with the following command:
|
|
|
|
$ cd
|
|
$ cvs checkout cvs
|
|
|
|
This will make the directory "cvs" in your current directory and
|
|
populate it with the appropriate CVS files and directories.
|
|
|
|
10) Remember to edit the modules file manually when sources are checked in
|
|
with "cvs import" or "cvs add". A copy of the modules file for editing
|
|
can usually be retrieved with the "cvs checkout modules" command, and
|
|
definitely with the "cvs checkout CVSROOT" command. See cvs(5).
|
|
|
|
11) Read the NEWS file to see what's new.
|
|
|
|
12) Hack away.

|
|
|
Detailed information about your interaction with "configure":
|
|
|
|
The "configure" script and its interaction with its options and the
|
|
environment is described here. For more detailed documentation about
|
|
"configure", please refer to the GNU Autoconf documentation.
|
|
|
|
Supported options are:
|
|
|
|
--srcdir=DIR Useful for compiling on many different
|
|
machines sharing one source tree.
|
|
--prefix=DIR The root of where to install the
|
|
various pieces of CVS (/usr/local).
|
|
--exec_prefix=DIR If you want executables in a
|
|
host-dependent place and shared
|
|
things in a host-independent place.
|
|
--with-diffutils[=PATH] Assume use of GNU diffutils is possible.
|
|
--with-gnugrep[=PATH] Assume use of GNU grep is possible.
|
|
|
|
The following environment variables override configure's default
|
|
behaviour:
|
|
|
|
CC If not set, tries to use gcc first,
|
|
then cc. Also tries to use "-g -O"
|
|
as options, backing down to -g
|
|
alone if that doesn't work.
|
|
INSTALL If not set, tries to use "install", then
|
|
"./install-sh" as a final choice.
|
|
RANLIB If not set, tries to determine if "ranlib"
|
|
is available, choosing "echo" if it doesn't
|
|
appear to be.
|
|
YACC If not set, tries to determine if "bison"
|
|
is available, choosing "yacc" if it doesn't
|
|
appear to be.
|
|
|
|
-------------------------------------------------------------------------------
|
|
Installation under Windows NT:
|
|
|
|
You may find interesting information in windows-NT/README.
|
|
|
|
1) Using Microsoft Visual C++ version 2.1, open the project `cvsnt.mak',
|
|
in the top directory of the CVS distribution.
|
|
2) Choose "Build cvs.exe" from the "Project" menu.
|
|
3) MSVC will place the executable file cvs.exe in WinDebug, or whatever
|
|
your target directory is.
|
