Patch between different versions in CVS [message #263662]

How is it to create a patch from first project version to second? The project
shared with CVS. I tried to use "Create patch" wizard, but it works only with
local changes.

It is a little bit unusual use case - could you please tell me what are
you trying to do?

I think that it is impossible to create diff file between two
versions...

There is no automatic feature to create a patch between revisions from
the repository. You might be able to simulate it by initiating a merge
from the later version into the older one and choosing the newer files
to overwrite the older ones. Once you bring those changes into your
workspace, you can create a patch and it should (if my thinking is
correct) represent the differences between the newer version and the
older one. this nice thing about the way Eclipse does merging is that
you can preview it safely and even bring merged changes into your
workspace to see and play with them; it does not commit anything until
you tell it to and thus you can easily throw away the merge and get back
to a known good state.

Alternatively, you can use command-line CVS to create the patch, as
described in this earlier thread:
http://dev.eclipse.org/newslists/news.eclipse.tools.jdt/msg2 2573.html

Hope this helps,
Eric

I have two projects from different repositories. First repo (CVS) is the
master, not my own repo. The second repo (SVN) is my own repo, copy of the
master repo with some my patches. I need to merge the master repo and my own.
I think, it can be do by the following steps:
1. Create patch between two versions from the master
2. Apply the patch to the slave

I have not tried it but I have an idea. There are plugins like
"BeyondCVS (http://sourceforge.net/projects/beyondcvs)" and
"ExternalDiff (http://sourceforge.net/projects/externaldiff/)". You can
install one of them and provide console diff utility to print difference
which is actually a patch if right parameters are used.
