diffs for all successive versions of a file?
I have a file, let's say blah.txt, which contains a line that's
something like:
xyz=37
In some previous versions of the file, it had different numbers there.
Maybe in one version, it was:
xyz=392384
And in another:
xyz=-9932
I would like to find out all values that it has ever had. Obviously I
can use "svn log" to find all revisions at which the file was changed,
and then do "svn diff -r N:M" for each successive pair. However, due to
the number of revisions, this would be somewhat of a pain.
So, what I would like is an easy way to automatically show all changes
ever on this file. I could then feed it to grep to get exactly what I
want. So, something like:
svn diffForEverySuccessiveRevision blah.txt | grep xyz
I could write a script to do this, based off of the "svn log" / "svn
diff -r N:M" method mentioned above, but I am hoping that there is
already an existing easy way to do it.
Thanks in advance for any help.

The script I was thinking of back then has been found (on another thread) by

Not exactly what the author was looking for, but this is an interesting
visual implementation in java I ran across recently:

This won't be much help, but maybe it'll jog someone elses memory:
I recall reading (a few months back, somewhere on the internet) about
a python script which did a sort of extended "svn blame", showing each
version of every line back to the first revision of the file. Problem
is, I can't remember what the script was called or where I read about
it. Maybe someone else has better memory than I.

I assume that for each "svn diff" invocation, the server has to do
all the necessary work from scratch. Couldn't this be implemented
on the server side in O(N) where N is the number of revisions for
which the file has changed?

Yes, use
http://svn.collab.net/repos/svn/trunk/contrib/client-side/svn_all_diffs.pl
which I wrote :)
