Before writing a replacement merge strategy for recursive, I decided
to first cleanup the merge API -- streamlining merge-recursive.h and
making it more readable.
Thanks to Dscho and Junio for feedback on v1 & v2.
Changes since v2:
* Addressed feedback from Junio and Dscho
* splitting a couple patches they highlighted as needing splitting
* fixed up several commit messages
* refactored cache-tree write-index-as-tree functions to share code
* created a separate commit with more sanity checks for merge_options
* Rebased on master (due to en/disable-dir-rename-in-recursive-merge)
* Found and fixed a minor bug in checkout; put this and related patches
at the beginning of the series
* Incorporated a patch from Stolee, though I removed the repo-settings
bits to make our patch series independent, and modified it to update
more existing code to use the new enum values.
Things I'd like reviewers to focus on, in priority order:
* Patch 12 -- I'm still unsure about cache-tree stuff
* The new patches (2, 3, 5, 23); in more detail:
* Patch 5 from Stolee -- I modified his original patch a fair amount
but left him as author; it's a simple patch, but extra eyes to
verify I didn't blame him for some nasty mistake of mine would be
good.
* Patch 2 fixes a minor issue with checkout -m
* Patch 23 is the more thorough sanity checks Junio suggested
* Patch 3 was mostly split out from what is now patch 4, so it was
mostly reviewed before but it now ties in nicely with patch 2.

@@ Commit message
1: <abbreviated commit hash>
0: "<empty tree>"
- Also, the code in merge_3way making use of opt->ancestor was overly
- complex because it tried to handle the case of opt->ancestor being NULL.
- We always set it first, though, so just add an assert that opt->ancestor
- is not NULL and simplify the surrounding code.
-
Tests have also been added to check that we get the right ancestor name
for each of the three cases.
+ Also, since merge_recursive() and merge_trees() have polar opposite
+ pre-conditions for opt->ancestor, document merge_recursive()'s
+ pre-condition with an assertion. (An assertion was added to
+ merge_trees() already a few commits ago.) The differences in
+ pre-conditions stem from two factors: (1) merge_trees() does not recurse
+ and thus does not have multiple sub-merges to worry about -- each of
+ which would require a different value for opt->ancestor, (2)
+ merge_trees() is only passed trees rather than commits and thus cannot
+ internally guess as good of a label. Thus, while external callers of
+ merge_trees() are required to provide a non-NULL opt->ancestor,
+ merge_recursive() expects to set this value itself.

- merge-recursive: fix minor memory leak in error condition
+ merge-recursive: future-proof update_file_flags() against memory leaks
- Returning before freeing the allocated buffer is suboptimal; as with
- elsewhere in the same function, make sure buf gets free'd.
+ There is a 'free_buf' label to which all but one of the error paths in
+ update_file_flags() jump; that error case involves a NULL buf and is
+ thus not a memory leak. However, make that error case execute the same
+ deallocation code anyway so that if anyone adds any additional memory
+ allocations or deallocations, then all error paths correctly deallocate
+ resources.

So, load the index in builtin/merge-recursive.c, reload the in-memory
index in builtin/stash.c, and modify the t3030 testcase to correctly
setup the index and make sure that the test fails in the expected way
- (meaning it reports a rename/rename conflict).
+ (meaning it reports a rename/rename conflict). This makes sure that

merge_finalize() function to make sure that all three entry points run
this function.
+ Note that there are two external callers of merge_trees(), one in

+ the limit kicks in and none are detected, it may help to have an
