This is CVS 1.3, RCS 5.6, GNU diff and patch for Linux.
This should be everything you need to do decent version control.
CVS is a frontend to RCS, which in turn uses diff and patch.
pcl-cvs, an Emacs frontend to CVS is also included.
If you extract this in your root directory, you need to
setenv CVSROOT /home/Master (csh users, in ~/.login)
or
export CVSROOT=/home/Master (bash/zsh, in ~/.{,z}profile)
Then get your favourite software package (e.g. Linux) and do
cd /tmp
tar xvzf linux-0.99.14.tar.gz
cd linux
cvs import -m LINUX_0_99_14 linux LINUX LINUX_0_99_14
cd ..
rm -rf linux
tar xvzf ALPHA-pl14a.tar.gz
cd linux
cvs import -m LINUX_0_99_14A linux LINUX LINUX_0_99_14A
cd ..
rm -rf linux
tar xvzf ALPHA-pl14b.tar.gz
cd linux
cvs import -m LINUX_0_99_14B linux LINUX LINUX_0_99_14B
cd ..
rm -rf linux
... and so on. To see the diffs between LINUX_0_99_14A and LINUX_0_99_14B
do
cvs rdiff -u -r LINUX_0_99_14A -r LINUX_0_99_14B linux
If you want to compile/hack the kernel, do
cd /usr/src
mv linux linux.old
cvs checkout linux
cd linux
[ hack away ... ]
If you want to see what you have changed:
cvs diff -u
or
cvs diff -u <file_or_dir>
When you feel confident that you want to commit your changes:
cd /usr/src/linux
cvs commit -m 'Your log message goes here'
cvs tag my_hacked_version_of_pl14b
Then look at your diffs:
cvs rdiff -u -r LINUX_0_99_14B -r my_hacked_version_of_pl14b
If you get conflicts after importing a new version (pl14c :-) ):
cd /usr/src/linux
cvs update -jLINUX:yesterday -jLINUX
which should do the same as
cvs update -j LINUX_0_99_14B -j LINUX_0_99_14C
and resolve the conflicts manually. Conflicts look like this
<<<<
your hack version...
||||
what patch expected...
====
the new stuff
>>>
You might want to do (in Emacs)
M-x dired /usr/src/linux
M-x grep -n '^<<<' `find -type f .`
or
M-x grep -n '^<<<' **/*(.) for zsh users
to correct the conflicts. Use C-x ` to go to the next conflict.
RTFM!!!! Really.
CVS/RCS is *not* trivial. Read the papers about CVS and RCS in the
/usr/doc directory.
I also uploaded the CVS paper as cvs-paper.ps.gz
Have fun,
Dirk
