Yes, they are possible. In fact, they sound a lot like the final
assignment for the half-day subversion introduction we're putting
together at my place of work.
OK. Let's assume you start with an empty repository. I've got one
here, and I'm accessing it using the "file" protocol. It's called
"lcs-repos".
Here's what my org-source looks like. Yours will be different, of
course:
org-source/adam.txt
org-source/ben.txt
org-source/charles.txt
org-source/daria.txt
First, I'm going to import modified-source into the repository as
"trunk"
$ svn import . file:///Users/bsmith/tmp/lcs-repos/trunk
Adding charles.txt
Adding adam.txt
Adding ben.txt
Adding daria.txt
Committed revision 1.
OK, in order to tag this I'll need a place to put the tag in your
repository. A tags directory will do the trick:
$ svn mkdir file:///Users/bsmith/tmp/lcs-repos/tags
Committed revision 2.
Now I'll tag trunk by copying it to tags under a new name
$ svn cp file:///Users/bsmith/tmp/lcs-repos/trunk \
file:///Users/bsmith/tmp/lcs-repos/tags/VERSION1
Committed revision 3.
Now we're going to need to check out a copy of trunk so that we can
modify it with the sources from modified-source.
$ svn co file:///Users/bsmith/tmp/lcs-repos/trunk trunk
A trunk/charles.txt
A trunk/adam.txt
A trunk/ben.txt
A trunk/daria.txt
Checked out revision 3.
This is what my modified-source looks like. You'll notice that
ben.txt is missing and elric.txt is new.
modified-source/adam.txt
modified-source/charles.txt
modified-source/daria.txt
modified-source/elric.txt
Now, I *could* just copy the contents of modified-source over those
in the copy of trunk that I just checked out, except this wouldn't
detect deletions. I'd miss the fact that modified-source no longer
contains ben.txt.
Instead, I'm going to first remove all working files from trunk.
Notice that this doesn't disturb the .svn administrative directory.
That's important.
$ cd trunk
trunk $ ls
adam.txt ben.txt charles.txt daria.txt
trunk $ rm *.txt
Now, I'll copy the contents of modified-source into the working
copy. Note what svn status tells me once this has been done.
trunk $ cp ../modified-source/*.txt .
trunk $ svn status
? elric.txt
M charles.txt
! ben.txt
M daria.txt
This means that 'elric.txt' is new in modified-source and needs to be
added. 'ben.txt' is missing in modified source and needs to be removed.
trunk $ svn add elric.txt
A elric.txt
trunk $ svn remove ben.txt
D ben.txt
Now svn status comes up clean:
trunk $ svn status
M charles.txt
D ben.txt
A elric.txt
M daria.txt
So, now we commit the changes and tag the result.
trunk $ svn ci .
Deleting ben.txt
Sending charles.txt
Sending daria.txt
Adding elric.txt
Transmitting file data ...
Committed revision 4.
$ svn cp file:///Users/bsmith/tmp/lcs-repos/trunk \
file:///Users/bsmith/tmp/lcs-repos/tags/VERSION2
Committed revision 5.
You can now ask the repository for a list of the differences between
your two versions by comparing the tags. I'm using the '--summarize'
option of svn diff, which was introduced in the 1.4 series. If
you're running an older version of svn, just leave it off and you'll
get the full textual differences of the files that have changed.
$ svn --summarize diff file:///Users/bsmith/tmp/lcs-repos/tags/
VERSION1 \
file:///Users/bsmith/tmp/lcs-repos/tags/VERSION2
D file:///Users/bsmith/tmp/lcs-repos/tags/VERSION1/ben.txt
M file:///Users/bsmith/tmp/lcs-repos/tags/VERSION1/charles.txt
A file:///Users/bsmith/tmp/lcs-repos/tags/VERSION1/elric.txt
M file:///Users/bsmith/tmp/lcs-repos/tags/VERSION1/daria.txt
