I don't see any fundamental reason why not, but I think it would be a significant amount of work. There are two main issues: 1. With CVS, it is possible to change things retroactively, such as changing which version of a file is included in a tag, or adding a new file to a tag, or changing whether a file is text vs. binary. And many people copy and/or rename files within the CVS repository itself (to get around CVS's inability to rename a file). This makes it look like the file has *always* existed under the new name and *never* existed under the old name. An incremental conversion tool would have to look carefully for such changes and either handle them properly or complain loudly and abort. 2. cvs2svn uses a lot of repository-wide information to make decisions about how to group CVSItems into changesets, and a lot of these decisions are based on heuristics. Incremental conversion would require that the decisions made in one cvs2svn run are recorded and treated as unalterable in subsequent runs. This hasn't been a priority in the Subversion world, because, frankly, what reason would a person have to stick with CVS instead of switching to Subversion, given that (1) they are intentionally so similar in workflow, an (2) there is no significant competition from other centralized SCMs? But of course until the distributed SCM playing field has been thinned out a bit, people will probably be reluctant to commit to one or the other. I don't expect to have time to implement incremental conversions in cvs2svn in the near future. (I'd much rather work on output back ends to other distributed SCMs.) But if any volunteers step forward (hint, hint) I would be happy to help them get started and answer their questions. I think that cvs2svn is quite hackable now, so the learning curve is hopefully much less frightening than when I started on the project :-) Michael - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
