Add the --set-upstream option to git pull/fetch
which lets the user set the upstream configuration
(branch.<current-branch-name>.merge and
branch.<current-branch-name>.remote) for the current branch.
A typical use-case is:
git clone http://example.com/my-public-fork
git remote add main http://example.com/project-main-repo
git pull --set-upstream main master
or, instead of the last line:
git fetch --set-upstream main master
git merge # or git rebase
This is mostly equivalent to cloning project-main-repo (which sets
upsteam) and then "git remote add" my-public-fork, but may feel more
natural for people using a hosting system which allows forking from
the web UI.
This functionality is analog to "git push --set-upstream".

A pax extended header record starts with a decimal number. Its value
is the length of the whole record, including its own length.
The calculation of that number in strbuf_append_ext_header() is off by
one in case the length of the rest is close to a higher order of
magnitude. This affects paths and link targets a bit shorter than 1000,
10000, 100000 etc. characters -- paths with a length of up to 100 fit
into the tar header and don't need a pax extended header.
The mistake has been present since the function was added by ae64bbc18c
("tar-tree: Introduce write_entry()", 2006-03-25).

If opt->buffer_output is less than 2, then merge_trees(),
merge_recursive(), and merge_recursive_generic() are all supposed to
flush the opt->obuf output buffer to stdout and release any memory it
holds. merge_trees() did not do this. Move the logic that handles this
for merge_recursive_internal() to merge_finalize() so that all three
methods handle this requirement.
Note that this bug didn't cause any problems currently, because there
are only two callers of merge_trees() right now (a git grep for
'merge_trees(' is misleading because builtin/merge-tree.c also defines a
'merge_tree' function that is unrelated), and only one of those is
called with buffer_output less than 2 (builtin/checkout.c), but it set
opt->verbosity to 0, for which there is only currently one non-error
message that would be shown: "Already up to date!". However, that one
message can only occur when the merge is utterly trivial (the merge base
tree exactly matches the merge tree), and builtin/checkout.c already
attempts a trivial merge via unpack_trees() before falling back to
merge_trees().
Also, if opt->buffer_output is 2, then the caller is responsible to
handle showing any output in opt->obuf and for free'ing it. This
requirement might be easy to overlook, so add a comment to
merge-recursive.h pointing it out. (There are currently two callers
that set buffer_output to 2, both in sequencer.c, and both of which
handle this correctly.)

We provided users with the ability to state whether they wanted rename

these fields had multiple configuration parameters for setting them,
with one being a fallback and the other being an override. However,
instead of implementing the logic for how to combine the multiple
source locations into the appropriate setting at config loading time,
we loaded and tracked both values and then made the code combine them
every time it wanted to check the overall value. This had a few
minor drawbacks:
* it seems more complicated than necessary
* it runs the risk of people using the independent settings in the
future and breaking the intent of how the options are used
together
* it makes merge_options more complicated than necessary for other
potential users of the API

Alternatively, you can view this as "make the merge functions behave
more similarly." merge-recursive has three different entry points:
merge_trees(), merge_recursive(), and merge_recursive_generic(). Two of
these would call diff_warn_rename_limit(), but merge_trees() didn't.
This lead to callers of merge_trees() needing to manually call
diff_warn_rename_limit() themselves. Move this to the new
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
sequencer.c and one in builtin/checkout.c. The one in sequencer.c is
cleaned up by this patch and just transfers where the call to
diff_warn_rename_limit() is made; the one in builtin/checkout.c is for
switching to a different commit and in the very rare case where the
warning might be triggered, it would probably be helpful to include
(e.g. if someone is modifying a file that has been renamed in moving to
the other commit, but there are so many renames between the commits that
the limit kicks in and none are detected, it may help to have an
explanation about why they got a delete/modify conflict instead of a
proper content merge in a renamed file).

We had a rule to enforce that the index matches head, but it was found

check wasn't triggered by merge_recursive() until it had first finished
all the intermediate merges to create virtual merge bases. That is a
potentially huge amount of computation (and writing of intermediate
merge results into the .git/objects directory) before it errors out and
says, in effect, "Sorry, I can't do any merging because you have some
local changes that would be overwritten."
Further, not enforcing this requirement earlier allowed other bugs (such
as an unintentional unconditional dropping and reloading of the index in
merge_recursive() even when no recursion was necessary), to mask bugs in
other callers (which were fixed in the commit prior to this one).

This is the bug that just won't die; there always seems to be another
form of it somewhere. See the commit message of 55f39cf755 ("merge:
fix misleading pre-merge check documentation", 2018-06-30) for a more
detailed explanation), but in short:
<quick summary>
builtin/merge.c contains this important requirement for merge
strategies:
...the index must be in sync with the head commit. The strategies are
responsible to ensure this.
This condition is important to enforce because there are two likely
failure cases when the index isn't in sync with the head commit:
* we silently throw away changes the user had staged before the merge
* we accidentally (and silently) include changes in the merge that
were not part of either of the branches/trees being merged
Discarding users' work and mis-merging are both bad outcomes, especially
when done silently, so naturally this rule was stated sternly -- but,
unfortunately totally ignored in practice unless and until actual bugs
were found. But, fear not: the bugs from this were fixed in commit
ee6566e8d7 ("[PATCH] Rewrite read-tree", 2005-09-05)
through a rewrite of read-tree (again, commit 55f39cf755 has a more
detailed explanation of how this affected merge). And it was fixed
again in commit
160252f816 ("git-merge-ours: make sure our index matches HEAD", 2005-11-03)
...and it was fixed again in commit
3ec62ad9ff ("merge-octopus: abort if index does not match HEAD", 2016-04-09)
...and again in commit
65170c07d4 ("merge-recursive: avoid incorporating uncommitted changes in a merge", 2017-12-21)
...and again in commit
eddd1a411d ("merge-recursive: enforce rule that index matches head before merging", 2018-06-30)
...with multiple testcases added to the testsuite that could be
enumerated in even more commits.
Then, finally, in a patch in the same series as the last fix above, the
documentation about this requirement was fixed in commit 55f39cf755
("merge: fix misleading pre-merge check documentation", 2018-06-30), and
we all lived happily ever after...
</quick summary>
Unfortunately, "ever after" apparently denotes a limited time and it
expired today. The merge-recursive rule to enforce that index matches
head was at the beginning of merge_trees() and would only trigger when
opt->call_depth was 0. Since merge_recursive() doesn't call
merge_trees() until after returning from recursing, this meant that the
check wasn't triggered by merge_recursive() until it had first finished
all the intermediate merges to create virtual merge bases. That is a
potentially HUGE amount of computation (and writing of intermediate
merge results into the .git/objects directory) before it errors out and
says, in effect, "Sorry, I can't do any merging because you have some
local changes that would be overwritten."
Trying to enforce that all of merge_trees(), merge_recursive(), and
merge_recursive_generic() checked the index == head condition earlier
resulted in a bunch of broken tests. It turns out that
merge_recursive() has code to drop and reload the cache while recursing
to create intermediate virtual merge bases, but unfortunately that code
runs even when no recursion is necessary. This unconditional dropping
and reloading of the cache masked a few bugs:
* builtin/merge-recursive.c: didn't even bother loading the index.
* builtin/stash.c: feels like a fake 'builtin' because it repeatedly
invokes git subprocesses all over the place, mixed with other
operations. In particular, invoking "git reset" will reset the
index on disk, but the parent process that invoked it won't
automatically have its in-memory index updated.
* t3030-merge-recursive.h: this test has always been broken in that it
didn't make sure to make index match head before running. But, it
didn't care about the index or even the merge result, just the
verbose output while running. While commit eddd1a411d
("merge-recursive: enforce rule that index matches head before
merging", 2018-06-30) should have uncovered this broken test, it
used a test_must_fail wrapper around the merge-recursive call
because it was known that the merge resulted in a rename/rename
conflict. Thus, that fix only made this test fail for a different
reason, and since the index == head check didn't happen until after
coming all the way back out of the recursion, the testcase had
enough information to pass the one check that it did perform.
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). This makes sure that
all callers actually make the index match head. The next commit will
then enforce the condition that index matches head earlier so this
problem doesn't return in the future.

In commit 7ca56aa076 ("merge-recursive: add a label for ancestor",
2010-03-20), a label was added for the '||||||' line to make it have
the more informative heading '|||||| merged common ancestors', with
the statement:
It would be nicer to use a more informative label. Perhaps someone
will provide one some day.
This chosen label was perfectly reasonable when recursiveness kicks in,
i.e. when there are multiple merge bases. (I can't think of a better
label in such cases.) But it is actually somewhat misleading when there
is a unique merge base or no merge base. Change this based on the
number of merge bases:
>=2: "merged common ancestors"
1: <abbreviated commit hash>
0: "<empty tree>"
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.

Instead of relying on magic values of -1, 0, and 1, split these

defaults for these config settings.

To avoid data loss, 'git worktree remove' refuses to delete a worktree
if it's dirty or contains untracked files. However, the error message
only mentions that the worktree "is dirty", even if the worktree in
question is in fact clean, but contains untracked files:
$ git worktree add test-worktree
Preparing worktree (new branch 'test-worktree')
HEAD is now at aa53e60 Initial
$ >test-worktree/untracked-file
$ git worktree remove test-worktree/
fatal: 'test-worktree/' is dirty, use --force to delete it
$ git -C test-worktree/ diff
$ git -C test-worktree/ diff --cached
$ # Huh? Where are those dirty files?!
Clarify this error message to say that the worktree "contains modified
or untracked files".

Completing configuration sections and variable names for the stuck
argument of 'git clone --config=<TAB>' requires a bit of extra care
compared to doing the same for the unstuck argument of 'git clone
--config <TAB>', because we have to deal with that '--config=' being
part of the current word to be completed.
Add an option to the __git_complete_config_variable_name_and_value()
and in turn to the __git_complete_config_variable_name() helper
functions to specify the current section/variable name to be
completed, so they can be used even when completing the stuck argument
of '--config='.
__git_complete_config_variable_value() already has such an option, and
thus no further changes were necessary to complete possible values
after 'git clone --config=section.name=<TAB>'.

The previous commits taught the completion script how to complete
configuration section, variable names, and their valus after 'git -c
<TAB>', and with a bit of foresight encapsulated all that in a
dedicated helper function. Use that function to complete the unstuck
argument of 'git config -c|--config <TAB>', which expect configuration
variables and values in the same 'section.name=value' form.
Note that handling the struck argument for 'git clone --config=<TAB>'
requires some extra care, so it will be done a separate patch.

'git config' expects a configuration variable's name and value in
separate options, so we complete values as they stand on their own on
the command line. 'git -c', however, expects them in a single option
joined by a '=' character, so we should be able to complete values
when they are following 'section.name=' in the same word.
Add new options to the __git_complete_config_variable_value() function
to allow callers to specify the current word to be completed and the
configuration variable whose value is to be completed, and use these
to complete possible values after 'git -c 'section.name=<TAB>'.
