Originally, if remote.<name>.tagopt was set, the --tags and option would
have no effect when given to git fetch. So if
tagopt="--no-tags"
git fetch --tags
would not actually fetch tags.
This patch changes this behavior to only follow what is written in the
config if there is no option passed by the command line.

Commit cd035b1c introduced the exec command to interactive rebase. In
doing so, it modified the way that skip_unnecessary_picks iterates through
the list of rebase commands so that it avoided collapsing multiple spaces
into a single space. This is necessary for example if the argument to the
exec command contains a path with multiple spaces in it.
The way it did this was by reading each line of rebase commands into a
single variable, and then breaking the individual components out using
echo, sed, and cut. It used the individual broken-out components for
decision making, and was still able to write the original line to the
output file from the variable it had saved it in. But, since we only
really need to look at anything other than the first element of the line
when a 'pick' command is encountered, and even that is only necessary when
we are still searching for "unnecessary" picks, and since newer rebase
commands like 'exec' may not even require a sha1 field, let's make our read
statement parse its input into a "command" variable, and a "rest" variable,
and then only break out the sha1 from $rest, and call git-rev-parse, when
absolutely necessary.
I think this future proofs this subroutine, avoids calling git-rev-parse
unnecessarily, and possibly with bogus arguments, and still accomplishes
the goal of not mangling the $rest of the rebase command.

Usually, diff frontends populate the output queue with filepairs without
any rename information and call diffcore_std() to sort the renames out.
When --follow is in effect, however, diff-tree family of frontend has a
hack that looks like this:
diff-tree frontend
-> diff_tree_sha1()
. populate diff_queued_diff
. if --follow is in effect and there is only one change that
creates the target path, then
-> try_to_follow_renames()
-> diff_tree_sha1() with no pathspec but with -C
-> diffcore_std() to find renames
. if rename is found, tweak diff_queued_diff and put a
single filepair that records the found rename there
-> diffcore_std()
. tweak elements on diff_queued_diff by
- rename detection
- path ordering
- pickaxe filtering
We need to skip parts of the second call to diffcore_std() that is related
to rename detection, and do so only when try_to_follow_renames() did find
a rename. Earlier 1da6175 (Make diffcore_std only can run once before a
diff_flush, 2010-05-06) tried to deal with this issue incorrectly; it
unconditionally disabled any second call to diffcore_std().
This hopefully fixes the breakage.

The "--follow" logic is called from diff_tree_sha1() function, but the
input trees to diff_tree_sha1() are not necessarily the top-level trees
(compare_tree_entry() calls it while it recursively descends into
subtrees). When a newly created path lives in somewhere deep in the
source hierarchy, e.g. "platform/", but the rename source is in a totally
different place in the destination hierarchy, e.g. "lang-api/src/com/...",
running "try_to_find_renames()" while base is set to "platform/" is a
wasted call.
We only need to run the rename following at the very top level.

Prior to c85c792 (pull --rebase: be cleverer with rebased upstream
branches, 2008-01-26), pull --rebase would run
git rebase $merge_head
which resulted in a call to
git format-patch ... --ignore-if-in-upstream $merge_head..$cur_branch
This resulted in patches from $merge_head..$cur_branch being applied, as
long as they did not already exist in $cur_branch..$merge_head.
Unfortunately, when upstream is rebased, $merge_head..$cur_branch also
refers to "old" commits that have already been rebased upstream, meaning
that many patches that were already fixed upstream would be reapplied.
This could result in many spurious conflicts, as well as reintroduce
patches that were intentionally dropped upstream.
So the algorithm was changed in c85c792 (pull --rebase: be cleverer with
rebased upstream branches, 2008-01-26) and d44e712 (pull: support rebased
upstream + fetch + pull --rebase, 2009-07-19). Defining $old_remote_ref to
be the most recent entry in the reflog for @{upstream} that is an ancestor
of $cur_branch, pull --rebase was changed to run
git rebase --onto $merge_head $old_remote_ref
which results in a call to
git format-patch ... --ignore-if-in-upstream $old_remote_ref..$cur_branch
The whole point of this change was to reduce the number of commits being
reapplied, by avoiding commits that upstream already has or had.
In the rebased upstream case, this change achieved that purpose. It is
worth noting, though, that since $old_remote_ref is always an ancestor of
$cur_branch (by its definition), format-patch will not know what upstream
is and thus will not be able to determine if any patches are already
upstream; they will all be reapplied.
In the non-rebased upstream case, this new form is usually the same as the
original code but in some cases $old_remote_ref can be an ancestor of
$(git merge-base $merge_head $cur_branch)
meaning that instead of avoiding reapplying commits that upstream already
has, it actually includes more such commits. Combined with the fact that
format-patch can no longer detect commits that are already upstream (since
it is no longer told what upstream is), results in lots of confusion for
users (e.g. "git is giving me lots of conflicts in stuff I didn't even
change since my last push.")
Cases where additional commits could be reapplied include forking from a
commit other than the tracking branch, or amending/rebasing after pushing.
Cases where the inability to detect upstreamed commits cause problems
include independent discovery of a fix and having your patches get
upstreamed by some alternative route (e.g. pulling your changes to a third
machine, pushing from there, and then going back to your original machine
and trying to pull --rebase).
Fix the non-rebased upstream case by ignoring $old_remote_ref whenever it
is contained in $(git merge-base $merge_head $cur_branch). This should
have no affect on the rebased upstream case.

(base + k) << m->shift

When an error is encountered, it calls add_rejected_file() which either
- directly displays the error message and stops if in plumbing mode
(i.e. if show_all_errors is not initialized at 1)
- or stores it so that it will be displayed at the end with display_error_msgs(),
Storing the files by error type permits to have a list of files for
which there is the same error instead of having a serie of almost
identical errors.
As each bind_overlap error combines a file and an old file, a list cannot be

The typical usage pattern would be to run a test (or simply a compilation
command) at given points in history.
The shell command is ran (from the worktree root), and the rebase is
stopped when the command fails, to give the user an opportunity to fix
the problem before continuing with "git rebase --continue".
This needs a little rework of skip_unnecessary_picks, which wasn't robust
enough to deal with lines like
exec >"file name with many spaces"
in the todolist. The new version extracts command, sha1 and rest from
each line, but outputs the line itself verbatim to avoid changing the

There are two ways a user might want to use "diff --relative":
1. For a file in a directory, like "subdir/file", the user
can use "--relative=subdir/" to strip the directory.
2. To strip part of a filename, like "foo-10", they can
use "--relative=foo-".
We currently handle both of those situations. However, if the user passes
"--relative=subdir" (without the trailing slash), we produce inconsistent
results. For the unified diff format, we collapse the double-slash of
"a//file" correctly into "a/file". But for other formats (raw, stat,
name-status), we end up with "/file".
We can do what the user means here and strip the extra "/" (and only a
slash). We are not hurting any existing users of (2) above with this
behavior change because the existing output for this case was nonsensical.

In the spirit of v1.4.2-rc3~34^2^2 (Call setup_git_directory() much
earlier, 2006-07-28), let run_builtin() take care of searching for a
repository for built-ins that want to make use of one if present.
So now you can mark your command with RUN_SETUP_GENTLY and use
nongit = !startup_info->have_repository;
in place of
prefix = setup_git_directory_gently(&nongit);
and everything will be the same, except the repository is
discovered a little sooner.
As v1.7.2~16^2 (2010-07-14) explains, this should allow more commands
to robustly use features like "git --paginate" that look at local
configuration before the command is actually run.

As v1.7.2~16^2 (git --paginate: paginate external commands

do not use RUN_SETUP are not finding GIT_DIR set correctly when
it is time to launch the pager from run_builtin(). If they
were to search for a repository sooner, then the outcome of such
early repository accesses would be more predictable and reliable.
The cmd_*() functions learn whether a repository was found through the
*nongit_ok return value from setup_git_directory_gently(). If
run_builtin() is to take care of the repository search itself, that
datum needs to be retrievable from somewhere else. Use the
startup_info struct for this.

The startup_info struct will collect information managed by the git
setup code, such as the prefix for relative paths passed on the
command line (i.e., path to the starting cwd from the toplevel of

In other words, startup_info is intended to be a collection of global
variables with results that were previously returned from setup
functions. This state is global anyway (since the cwd is), even
if it is not currently tracked that way. Letting these values persist
means there is more flexibility in deciding when to run setup.
For now, the struct is empty.

Sparse checkout narrows worktree down based on the skip-worktree bit
before and after $GIT_DIR/info/sparse-checkout application. If it does
not have that bit before but does after, a narrow is detected and the
file will be removed from worktree.
New files added by merge, however, does not have skip-worktree bit. If
those files appear to be outside checkout area, the same rule applies:
the file gets removed from worktree even though they don't exist in
worktree.
Just pretend they have skip-worktree before in that case, so the rule
