CVS import: Changing/cleaning authors and committers

CVS import: Changing/cleaning authors and committers

[Robert Haines]

Hi all,

I am very new to git, but already impressed! I am in the process of  
converting my old CVS repos into git. So far so good, it all works  
with 'git cvsimport' but I was wondering about the author and  
committer names. All mine have come out as the username of the person  
who committed the change into CVS:

author xxcguxx <xxcguxx>
committer xxcguxx <xxcguxx>

I was wondering if it would be able to go through and change all that  
to:

author Name <email@address>
etc

Is this something that can be retrospectively done? Is it something  
that can be done during cvsimport? Is it even doable?

Any suggestions gratefully received!

Best wishes,
Rob

If everything else fails, read the documentation.

man git-cvsimport

[...]
	-A <author-conv-file>
	    CVS by default uses the Unix username when writing its
	    commit logs. Using this option and an author-conv-file
	    in this format

David already answered the second question, and it is probably simpler
to just redo the import with -A unless there is some complication with
that (like you no longer have access to the CVS files).

However, to answer your first question: it can be fixed after the fact
by rewriting history within the git repository; see git-filter-branch.

So ideally I would have spotted the -A flag originally! I have had  
something of an information overload with git, gitweb and so on  
recently.

I decided to re-import with the -A flag as there is (much) less  
chance of me mucking it up!

Thanks,
Rob
