Re: CVS diff after a rename

Hi Torsten/Jacob,
 
This can be cause by either TortoiseCVS or by CVSNT Server.
 
Performing 'checkout' on a renamed file is a very tricky operation - and
each version of CVSNT Server does it quite differently - the difficulty
is finding the correct name of the file for the given circumstances of
the checkout - Tony rarely checks out individual files - so the logic
works when you checkout a directory - but individual files often have
weird errors.  eg: some versions require that the 'original' name always
be used, other versions will get the name right/except sometimes... 
 
Therefore it is very important to include the CVSNT Server version
number with any error report for rename.
 
I think I have also seen this caused by TortoiseCVS on older builds -
though I haven't tried to test it on the recent 1.12.x.  In this case if
I rename a file then fire up revision graph and then choose a revision
'before' the rename - TortoiseCVS doesn't use the previous name of the
file to 'checkout' the old revision - so it cannot be found.  Or if I
checkout a 'branch' (that uses the old name of the file) and try do diff
the 'HEAD' (where it is renamed) then TortoiseCVS doesn't use the 'new'
name of the file.
 
I've often wondered if there is a more 'efficient' way to do a
side-by-side diff than checking out two complete revisions.  eg: copy
the existing sandbox file, perform a 'cvs diff' and then running 'patch'
to create the second file (would only work for text files)- or copy the
existing sandbox, perform a 'cvs up -r' (would work for text and binary
files - and the protocol would use a 'diff' patch algorithm).
 
Regards,
 
 
Arthur

		In TortoiseCVS, version 1.10.10, I went ahead and
renamed a file, despite the warning I was presented.  Now, whenever I
attempt a diff through TortoiseCVS, I get an error from the CVS server,
saying "cannot find module 'blah/blah/blah' - ignored."  The "blahs" in
the path correctly reflect my directory and file names.  Strangely, I
can do a cvs diff from the command line, and everything works fine.  Is
there any way I can restore diffability for my renamed files?

	Please describe the exact command that TortoiseCVS runs, and the
command that you run yourself.
