Build-in merge-recursive This makes write_tree_from_memory(), which writes the active cache as a tree and returns the struct tree for it, available to other code. It also makes available merge_trees(), which does the internal merge of two trees with a known base, and merge_recursive(), which does the recursive internal merge of two commits with a list of common ancestors. The first two of these will be used by checkout -m, and the third is presumably useful in general, although the implementation of checkout -m which entirely matches the behavior of the shell version does not use it (since it ignores the difference of ancestry between the old branch and the new branch).

merge-recursive: introduce merge_options This makes it possible to avoid passing the labels of branches as arguments to merge_recursive(), merge_trees() and merge_recursive_generic(). It also takes care of subtree merge, output buffering, verbosity, and rename limits - these were global variables till now in merge-recursive.c. A new function, named init_merge_options(), is introduced as well, it clears the struct merge_info, then initializes with default values, finally updates the default values based on the config and environment variables.

struct merge_options {
merge_trees(): add ancestor label parameter for diff3-style output Commands using the merge_trees() machinery will present conflict hunks in output something like what ‘diff3 -m’ produces if the merge.conflictstyle configuration option is set to diff3. The output lacks the name of the merge base on the ||||||| line of the output, and tools can misparse the conflict hunks without it. Add a new o->ancestor parameter to merge_trees() for use as a label for the ancestor in conflict hunks. If o->ancestor is NULL, the output format is as before. All callers pass NULL for now. If o->ancestor is non-NULL and both branches renamed the base file to the same name, that name is included in the conflict hunk labels. Even if o->ancestor is NULL I think this would be a good change, but this patch only does it in the non-NULL case to ensure the output format does not change where it might matter.

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.

MERGE_RECURSIVE_OURS,
enums: omit trailing comma for portability Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.
