The primary problem with git-subtree was that I ended up with a temporary file directory containing 100+K files, which I tracked back to being used to manage the commit-to-tree mapping. On Windows, at least, that literally slowed down the process to a crawl. If one doesn't use replant, is your tool different from git-subtree? No, it is not different. However, my tool will use RAM, not diskspace to manage information. That is some valuable input. It can help improve git-subtree for Windows users, or replace it by something else.

Yngve N. Pettersen (Developer Opera Software ASA) venit, vidit, dixit 18.12.2012 15:51: Hello all, Today Opera Software released the Git-splitter, a small tool for sub-modularizing code in a git repo, with complete commit history, under the Apache 2.0 license. It's functionality is similar to git-subtree, but also include a command for reversing the process. Is there something keeping you technically from adding a join command to git-subtree? The code is hosted on GitHub: https://github.com/operasoftware/git-splitter We have announced the release as part of another announcement of released code at the Opera Security Group home page: http://my.opera.com/securitygroup/blog/2012/12/18/tls-prober-source-released-under-apache-2-0-license -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
