Hello, people. I've been reading this list for quite a while now, and trying to understand what's going on, and wandering around in the code. There are some concepts I'd like you to help me understand better: 1) What are plumbing and porcelain functions, methods, APIs... What's the meaning of that classification and difference between the two? 2) What's going on about cache-tree not being able to handle empty trees, or something like that? You mean Git doesn't store empty directories in repositories? 3) And what are symbolic references? Are they just an alias I can attach to branches and tags, like symbolic links in Linux that I can attach to folders and files? If you prefer, just a link to some material I can read to understand those concepts better would be great. :) Thank you very much! -- JoÃo Paulo Melo de Sampaio Computer Engineering Student @ UFSCar Website: http://www.jpmelos.com Twitter: twitter.com/jpmelos (@jpmelos) -- 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
