In the meantime, I've made some progress too. I made ls-tree, which will just convert the tree object to a human readable (and script processable) form, and wrapper gitls.sh, which will also try to guess the tree ID. parent-id will just return the commit ID(s) of the previous commit(s), practical if you want to diff against the previous commit easily etc. And finally, there is gitdiff.sh, which will produce a diff of any two trees. Everything is again available at <a href="http://pasky.or.cz/~pasky/dev/git/">http://pasky.or.cz/~pasky/dev/git/</a> and again including .dircache, even though it's invisible in the index. The cumulative patch (against 0.03) is there as well as below, generated by the ./gitdiff.sh 0af20307bb4c634722af0f9203dac7b3222c4a4f command. The empty entries are changed modes (664 vs 644), I will yet have to think about how to denote them if the content didn't change; or I might ignore them altogether...? You can obviously fetch any arbitrary change by doing the appropriate gitdiff.sh call. You can find the ids in the ChangeLog, which was generated by the plain ./gitlog.sh command. (That is for HEAD. 0af20307bb4c634722af0f9203dac7b3222c4a4f is the last commit on the Linus' branch, pass that to gitlog.sh to get his ChangeLog. ;-) Next, I will probably do some bk-style pull tool. Or perhaps first a gitpatch.sh which will verify the sha1s and do the mode changes. Linus, could you please have a look and tell me what do you think about it so far?
