5313827f7e i18n: notes: mark strings for translation
Mark strings of messages for the user as translatable.

Update tests t3310-notes-merge-manual-resolve.sh and
t3320-notes-merge-worktrees.sh to reflect new translatable messages.

Tests that grep for .git/NOTES_MERGE_WORKTREE reflect the translatable
string "Automatic notes merge failed. Fix conflicts in %s and [...]".

8785c42532 i18n: advice: internationalize message for conflicts
Mark message for translation telling the user she has conflicts to
resolve. Expose each particular use case, in order to enable translating
entire sentences which would facilitate translating into other
languages.

Change "Pull" to lowercase to match other instances. Update test
t5520-pull.sh, that relied on the old error message, to use the new one.

Although we loose in source code conciseness, we would gain better
translations because translators can 1) translate the entire sentence,
including those terms concerning Git (committing, merging, etc) 2) have
leeway to adapt to their languages.

070b7e4416 i18n: builtin/remote.c: fix mark for translation
The second string inside _() was not being extracted for translation by
xgettext, meaning that, although the string was passed to gettext, there
was no translation available.

Mark each individual string instead of marking the result of ternary if.

Many commands normalize command line arguments from NFD to NFC

90a78b83e0 diff: run arguments through precompose_argv
When running diff commands, a pathspec containing decomposed
unicode code points is not converted to precomposed unicode form
under Mac OS X, but we normalize the paths in the index and the
history to precomposed form on that platform.  As a result, the
pathspec would not match and no diff is shown.

Unlike many builtin commands, the "diff" family of commands do
not use parse_options(), which is how other builtin commands
indirectly call precompose_argv() to normalize argv[] into
precomposed form on Mac OSX.  Teach these commands to call
precompose_argv() themselves.

Note that precomopose_argv() normalizes not just paths but all
command line arguments, so things like "git diff -G $string"
when $string has the decomposed form would first be normalized
into the precomposed form and would stop hitting the same string
in the decomposed form in the diff output with this change.

It is not a problem per-se, as "log" family of commands already use
parse_options() and call precompose_argv()--we can think of this
change as making the "diff" family of commands behave in a similar
way as the commands in the "log" family.

50b26f5612 Merge branch 'jc/commit-tree-ignore-commit-gpgsign'
"git commit-tree" plumbing command required the user to always sign
its result when the user sets the commit.gpgsign configuration
variable, which was an ancient mistake.  Rework "git rebase" that
relied on this mistake so that it reads commit.gpgsign and pass (or
not pass) the -S option to "git commit-tree" to keep the end-user
expectation the same, while teaching "git commit-tree" to ignore
the configuration variable.  This will stop requiring the users to
sign commit objects used internally as an implementation detail of
"git stash".

89044baa8b submodule: stop sanitizing config options
The point of having a whitelist of command-line config
options to pass to submodules was two-fold:

  1. It prevented obvious nonsense like using core.worktree
     for multiple repos.

  2. It could prevent surprise when the user did not mean
     for the options to leak to the submodules (e.g.,
     http.sslverify=false).

For case 1, the answer is mostly "if it hurts, don't do
that". For case 2, we can note that any such example has a
matching inverted surprise (e.g., a user who meant
http.sslverify=true to apply everywhere, but it didn't).

So this whitelist is probably not giving us any benefit, and
is already creating a hassle as people propose things to put
on it. Let's just drop it entirely.

Note that we still need to keep a special code path for
"prepare the submodule environment", because we still have
to take care to pass through $GIT_CONFIG_PARAMETERS (and
block the rest of the repo-specific environment variables).

We can do this easily from within the submodule shell
script, which lets us drop the submodule--helper option
entirely (and it's OK to do so because as a "--" program, it
is entirely a private implementation detail).

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag.  It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge.  The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."

6694856153 commit-tree: do not pay attention to commit.gpgsign
ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) introduced a
"signed commit" by teaching the --[no]-gpg-sign option and the
commit.gpgsign configuration variable to various commands that
create commits.

Teaching these to "git commit" and "git merge", both of which are
end-user facing Porcelain commands, was perfectly fine.  Allowing
the plumbing "git commit-tree" to suddenly change the behaviour to
surprise the scripts by paying attention to commit.gpgsign was not.

Among the in-tree scripts, filter-branch, quiltimport, rebase and
stash are the commands that run "commit-tree".  If any of these
wants to allow users to always sign every single commit, they should
offer their own configuration (e.g. "filterBranch.gpgsign") with an
option to disable signing (e.g. "git filter-branch --no-gpgsign").

Ignoring commit.gpgsign option _obviously_ breaks the backward
compatibility, but it is easy to follow the standard pattern in
scripts to honor whatever configuration variable they choose to
follow.  E.g.

	case $(git config --bool commit.gpgsign) in
	true) sign=-S ;;
	*) sign= ;;
	esac &&
	git commit-tree $sign ...whatever other args...

Do so to make sure that "git rebase" keeps paying attention to the
configuration variable, which unfortunately is a documented mistake.

Reroute the output of stdout to stderr as it is just informative
messages, not to be consumed by machines.

This should not regress any scripts that try to parse the
current output, as the output is already internationalized

We want to init submodules from the helper for `submodule update`
in a later patch and the stdout output of said helper is consumed
by the parts of `submodule update` which are still written in shell.
So we have to be careful which messages are on stdout.

4638728c63 submodule--helper: move config-sanitizing to submodule.c
These functions should be used by any code which spawns a
submodule process, which may happen in submodule.c (e.g.,
for spawning fetch). Let's move them there and make them
public so that submodule--helper can continue to use them.

Since they're now public, let's also provide a basic overview
of their intended use.

9cea46cdda pack-objects: warn on split packs disabling bitmaps
It can be tempting for a server admin to want a stable set of
long-lived packs for dumb clients; but also want to enable bitmaps
to serve smart clients more quickly.

Unfortunately, such a configuration is impossible; so at least warn
users of this incompatibility since commit 21134714 (pack-objects:
turn off bitmaps when we split packs, 2014-10-16).

Tested the warning by inspecting the output of:

	make -C t t5310-pack-bitmaps.sh GIT_TEST_OPTS=-v

bb52995f3e format-patch: introduce format.useAutoBase configuration
This allows to record the base commit automatically, it is equivalent
to set --base=auto in cmdline.

The format.useAutoBase has lower priority than command line option,
so if user set format.useAutoBase and pass the command line option in
the meantime, base_commit will be the one passed to command line
option.

3de665175f format-patch: introduce --base=auto option
Introduce --base=auto to record the base commit info automatically, the
base_commit will be the merge base of tip commit of the upstream branch
and revision-range specified in cmdline.

fa2ab86d18 format-patch: add '--base' option to record base tree info
Maintainers or third party testers may want to know the exact base tree
the patch series applies to. Teach git format-patch a '--base' option
to record the base tree info and append it at the end of the first
message (either the cover letter or the first patch in the series).

The base tree info consists of the "base commit", which is a well-known
commit that is part of the stable part of the project history everybody
else works off of, and zero or more "prerequisite patches", which are
well-known patches in flight that is not yet part of the "base commit"
that need to be applied on top of "base commit" in topological order
before the patches can be applied.

The "base commit" is shown as "base-commit: " followed by the 40-hex of
the commit object name.  A "prerequisite patch" is shown as
"prerequisite-patch-id: " followed by the 40-hex "patch id", which can
be obtained by passing the patch through the "git patch-id --stable"
command.

Imagine that on top of the public commit P, you applied well-known
patches X, Y and Z from somebody else, and then built your three-patch
series A, B, C, the history would be like:

---P---X---Y---Z---A---B---C

With "git format-patch --base=P -3 C" (or variants thereof, e.g. with
"--cover-letter" of using "Z..C" instead of "-3 C" to specify the
range), the base tree information block is shown at the end of the
first message the command outputs (either the first patch, or the
cover letter), like this:

base-commit: P
prerequisite-patch-id: X
prerequisite-patch-id: Y
prerequisite-patch-id: Z

d22eb04475 clone: add --shallow-submodules flag
When creating a shallow clone of a repository with submodules, the depth
argument does not influence the submodules, i.e. the submodules are done
as non-shallow clones. It is unclear what the best default is for the
depth of submodules of a shallow clone, so we need to have the possibility
to do all kinds of combinations:

* shallow super project with shallow submodules
  e.g. build bots starting always from scratch. They want to transmit
  the least amount of network data as well as using the least amount
  of space on their hard drive.
* shallow super project with unshallow submodules
  e.g. The superproject is just there to track a collection of repositories
  and it is not important to have the relationship between the repositories
  intact. However the history of the individual submodules matter.
* unshallow super project with shallow submodules
  e.g. The superproject is the actual project and the submodule is a
  library which is rarely touched.

The new switch to select submodules to be shallow or unshallow supports
all of these three cases.

It is easy to transition from the first to the second case by just
unshallowing the submodules (`git submodule foreach git fetch
--unshallow`), but it is not possible to transition from the second to the
first case (as we would have already transmitted the non shallow over
the network). That is why we want to make the first case the default in
case of a shallow super project. This leads to the inconvenience in the
second case with the shallow super project and unshallow submodules,
as you need to pass `--no-shallow-submodules`.

f276cae187 Merge branch 'en/merge-trivial-fix'
When "git merge" notices that the merge can be resolved purely at
the tree level (without having to merge blobs) and the resulting
tree happens to already exist in the object store, it forgot to
update the index, which lead to an inconsistent state for later
operations.
