merge-recursive: handle D/F conflict case more carefully.
When a path D that originally was blob in the ancestor was
modified on our branch while it was removed on the other branch,
we keep stages 1 and 2, and leave our version in the working
tree. If the other branch created a path D/F, however, that
path can cleanly be resolved in the index (after all, the
ancestor nor we do not have it and only the other side added),
but it cannot be checked out. The issue is the same when the
other branch had D and we had renamed it to D/F, or the ancestor
had D/F instead of D (so there are four combinations).
Do not stop the merge, but leave both D and D/F paths in the
index so that the user can clear things up.
merge-recursive: do not barf on "to be removed" entries.
When update-trees::threeway_merge() decides that a path that
exists in the current index (and HEAD) is to be removed, it
leaves a stage 0 entry whose mode bits are set to 0. The code
mistook it as "this stage wants the blob here", and proceeded
to call update_file_flags() which ended up trying to put the
mode=0 entry in the index, got very confused, and ended up
barfing with "do not know what to do with 000000".
Since threeway_merge() does not handle case #10 (one side
removes while the other side does not do anything), this is not
a problem while we refuse to merge branches that have D/F
conflicts, but when we start resolving them, we would need to be
able to remove cache entries, and at that point it starts to
matter.
Treat D/F conflict entry more carefully in unpack-trees.c::threeway_merge()
This fixes three buglets in threeway_merge() regarding D/F
conflict entries.
* After finishing with path D and handling path D/F, some stages
have D/F conflict entry which are obviously non-NULL. For the
purpose of determining if the path D/F is missing in the
ancestor, they should not be taken into account.
* D/F conflict entry is a marker to say "this stage does _not_
have the path", so do not send them to keep_entry().
Case #10 is not handled with unpack-trees.c:threeway_merge()
internally, unless under the agressive rule, and it is not a
bug. As the test expects, ND (one side did not do anything,
other side deleted) case was meant to be handled by the caller's
policy (e.g. git-merge-one-file or git-merge-recursive).
Some oneline descriptions are just too long. In shortlog, it looks much
nicer when they are wrapped. Since print_wrapped_text() is UTF-8 aware,
it also works with those descriptions.

Unlike 'patch --fuzz=NUM', which specifies the number of lines allowed

add_cache_entry(): removal of file foo does not conflict with foo/bar
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.
git-push to multiple locations does not stop at the first failure
When pushing into multiple repositories with git push, via
multiple URL in .git/remotes/$shorthand or multiple url
variables in [remote "$shorthand"] section, we used to stop upon
the first failure. Continue the operation and report the
failure at the end.
This came up on #git when somebody was getting 'unable to create
./objects/tmp_oXXXX' but sweared he had write permission to that
directory. It turned out that the repository URL was changed
and he was accessing a repository he does not have a write
permission anymore.
I am not sure how much this would have helped somebody who
believed he was accessing location when the permission of that
location was changed while he was looking the other way, though.
But giving more information on the error path would be better,
and the next change would be helped with this as well.

This moves the knowledge about .git/config usage out of refs.c and into

This function was not called "add_file_to_cache()" only because
an ancient program, update-cache, used that name as an internal
function name that does something slightly different. Now that
is gone, we can take over the better name.
The plan is to name all functions that operate on the default
index xxx_cache(). Later patches create a variant of them that
take an explicit parameter xxx_index(), and then turn
xxx_cache() functions into macros that use "the_index".
Rename internal function "add_file_to_cache" in builtin-update-index.c
I'd like to consistently name all index-layer functions that
operate on the default index xxx_cache(), and this application
specific function interferes with the plan.
Propagate cache error internal to refresh_cache() via parameter.
The function refresh_cache() is the only user of cache_errno
that switches its behaviour based on what internal function
refresh_cache_entry() finds; pass the error status back in a
parameter passed down to it, to get rid of the global variable
cache_errno.
Fix bogus error message from merge-recursive error path
This error message should not usually trigger, but the function
make_cache_entry() called by add_cacheinfo() can return early
without calling into refresh_cache_entry() that sets cache_errno.
Also the error message had a wrong function name reported, and
it did not say anything about which path failed either.
Previously, a binary file in the diffstat would show as:
some-binary-file.bin | Bin
The space after the "Bin" was never used. This patch changes binary
lines in the diffstat to be:
some-binary-file.bin | Bin 12345 -> 123456 bytes
The very nice "->" notation was suggested by Johannes Schindelin, and
shows the before and after sizes more clearly than "+" and "-" would.
If a size is 0 it's not shown (although it would probably be better to
treat no-file differently from zero-byte-file).
The user can see what changed in the binary file, and how big the new
file is. This is in keeping with the information in the rest of the
diffstat.
The diffstat_t members "added" and "deleted" were unused when the file
was binary, so this patch loads them with the file sizes in
builtin_diffstat(). These figures are then read in show_stats() when
the file is marked binary.

Fix lost-found to show commits only referenced by reflogs
Prior to 1.5.0 the git-lost-found utility was useful to locate
commits that were not referenced by any ref. These were often
amends, or resets, or tips of branches that had been deleted.
Being able to locate a 'lost' commit and recover it by creating a
new branch was a useful feature in those days.
Unfortunately 1.5.0 added the reflogs to the reachability analysis
performed by git-fsck, which means that most commits users would
consider to be lost are still reachable through a reflog. So most
(or all!) commits are reachable, and nothing gets output from
git-lost-found.
Now git-fsck can be told to ignore reflogs during its reachability
analysis, making git-lost-found useful again to locate commits
that are no longer referenced by a ref itself, but may still be
referenced by a reflog.

This loosens the over-eager verify_absent() check that gets

from the other branch, which is a tad expensive but this is a
less common case.

This corrects the interface mistake of the previous one, and

We can add the calls to set_alternate_index_output() to other
plumbing commands that update the index if/when needed.
_GIT_INDEX_OUTPUT: allow plumbing to output to an alternative index file.
When defined, this allows plumbing commands that update the
index (add, apply, checkout-index, merge-recursive, mv,
read-tree, rm, update-index, and write-tree) to write their
resulting index to an alternative index file while holding a
lock to the original index file. With this, git-commit that
jumps the index does not have to make an extra copy of the index
file, and more importantly, it can do the update while holding
the lock on the index.
However, I think the interface to let an environment variable
specify the output is a mistake, as shown in the documentation.
If a curious user has the environment variable set to something
other than the file GIT_INDEX_FILE points at, almost everything
will break. This should instead be a command line parameter to
tell these plumbing commands to write the result in the named
file, to prevent stupid mistakes.
