René Scharfe	10a3fb00eb	match-trees: factor out fill_tree_desc_strict Deduplicate code by moving tree_desc initialization into a helper function, fill_tree_desc_strict. It is like fill_tree_descriptor, except that it only accepts tree hashes and no tree references (tags, commits). No functional change.

René Scharfe	d8febde370	match-trees: simplify score_trees() using tree_entry() Convert the loop in score_trees() to tree_entry(). The code becomes shorter and simpler because the calls to update_tree_entry() are not needed any more. Another benefit is that we need less variables to track the current tree entries; as a side-effect of that the compiler has an easier job figuring out the control flow and thus can avoid false warnings about uninitialized variables. Using struct name_entry also allows the use of tree_entry_len() for finding the path length instead of strlen(), which may be slightly more efficient. Also unify the handling of missing entries in one of the two trees (i.e. added or removed files): Just set cmp appropriately first, no matter if we ran off the end of a tree or if we actually have two entries to compare, and check its value a bit later without duplicating the handler code.

Junio C Hamano	85e51b783c	Make "subtree" part more orthogonal to the rest of merge-recursive. This makes "subtree" more orthogonal to the rest of recursive merge, so that you can use subtree and ours/theirs features at the same time. For example, you can now say: git merge -s subtree -Xtheirs other to merge with "other" branch while shifting it up or down to match the shape of the tree of the current branch, and resolving conflicts favoring the changes "other" branch made over changes made in the current branch. It also allows the prefix used to shift the trees to be specified using the "-Xsubtree=$prefix" option. Giving an empty prefix tells the command to figure out how much to shift trees automatically as we have always done. "merge -s subtree" is the same as "merge -s recursive -Xsubtree=" (or "merge -s recursive -Xsubtree"). Based on an old patch done back in the days when git-merge was a script; Avery ported the script part to builtin-merge.c. Bugs in shift_tree() is mine.

Junio C Hamano	a6080a0a44	War on whitespace This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

Junio C Hamano	68faf68938	A new merge stragety 'subtree'. This merge strategy largely piggy-backs on git-merge-recursive. When merging trees A and B, if B corresponds to a subtree of A, B is first adjusted to match the tree structure of A, instead of reading the trees at the same level. This adjustment is also done to the common ancestor tree. If you are pulling updates from git-gui repository into git.git repository, the root level of the former corresponds to git-gui/ subdirectory of the latter. The tree object of git-gui's toplevel is wrapped in a fake tree object, whose sole entry has name 'git-gui' and records object name of the true tree, before being used by the 3-way merge code. If you are merging the other way, only the git-gui/ subtree of git.git is extracted and merged into git-gui's toplevel. The detection of corresponding subtree is done by comparing the pathnames and types in the toplevel of the tree. Heuristics galore! That's the git way ;-).
