Split "git-pull-script" into two parts Separate out the merge resolve from the actual getting of the data. Also, update the resolve phase to take advantage of the fact that we don't need to do the commit->tree object lookup by hand, since all the actors involved happily just act on a commit object these days.

Introduce GIT_DIR environment variable. During the mailing list discussion on renaming GIT_ environment variables, people felt that having one environment that lets the user (or Porcelain) specify both SHA1_FILE_DIRECTORY (now GIT_OBJECT_DIRECTORY) and GIT_INDEX_FILE for the default layout would be handy. This change introduces GIT_DIR environment variable, from which the defaults for GIT_INDEX_FILE and GIT_OBJECT_DIRECTORY are derived. When GIT_DIR is not defined, it defaults to ".git". GIT_INDEX_FILE defaults to "$GIT_DIR/index" and GIT_OBJECT_DIRECTORY defaults to "$GIT_DIR/objects". Special thanks for ideas and discussions go to Petr Baudis and Daniel Barkalow. Bugs are mine ;-) Signed-off-by: Junio C Hamano <junkio@cox.net>

# Resolve two trees.

Add "git-sh-setup-script" for common git shell script setup It sets up the normal git environment variables and a few helper functions (currently just "die()"), and returns ok if it all looks like a git archive. So use it something like . git-sh-setup-script || die "Not a git archive" to make the rest of the git scripts more careful and readable.

. git-sh-setup-script || die "Not a git archive"
[PATCH] git-resolve-script: Add LAST_MERGE and use git-rev-parse Make git-resolve-script only write MERGE_HEAD if a merge actually occurred. All merge failures leave ORIG_HEAD and LAST_MERGE behind (instead of ORIG_HEAD and MERGE_HEAD). Use git-rev-parse to expand arguments (and check for bad ones).

Clean up different special *HEAD handling We codify the following different heads (in addition to the main "HEAD", which points to the current branch, of course): - FETCH_HEAD Populated by "git fetch" - ORIG_HEAD The old HEAD before a "git pull/resolve" (successful or not) - LAST_MERGE The HEAD we're currently merging in "git pull/resolve" - MERGE_HEAD The previous head of a unresolved "git pull", which gets committed by a "git commit" after manually resolving the result We used to have "MERGE_HEAD" be populated directly by the fetch, and we removed ORIG_HEAD and LAST_MERGE too aggressively.

More work on merging with git-read-tree.. Add a "-u" flag to update the tree as a result of a merge. Right now this code is way too anal about things, and fails merges it shouldn't, but let me fix up the different cases and this will allow for much smoother merging even in the presense of dirty data in the working tree.

Fix git-resolve-script. I'd stupidly forgotten one merge_head -> merge conversion, and all my tests were for the fast-forward case that never triggered the bug.
