daf9f6499f i18n: builtin/pull.c: split strings marked for translation
Split string "If you wish to set tracking information
for this branch you can do so with:\n" to match occurring string in
git-parse-remote.sh. In this case, the translator handles it only once.

On the other hand, the translations of the string that were already made
are mark as fuzzy and the translator needs to correct it herself.

a127331cd8 mv: allow moving nested submodules
When directories are moved using `git mv` all files in the directory
have been just moved, but no further action was taken on them. This
was done by assigning the mode = WORKING_DIRECTORY to the files
inside a moved directory.

submodules however need to update their link to the git directory as
well as updates to the .gitmodules file. By removing the condition of
`mode != INDEX` (the remaining modes are BOTH and WORKING_DIRECTORY) for
the required submodule actions, we perform these for submodules in a
moved directory.

f5cc612916 Merge branch 'jk/branch-shortening-funny-symrefs'
A change back in version 2.7 to "git branch" broke display of a
symbolic ref in a non-standard place in the refs/ hierarchy (we
expect symbolic refs to appear in refs/remotes/*/HEAD to point at
the primary branch the remote has, and as .git/HEAD to point at the
branch we locally checked out).

3604242f08 submodule: port init from shell to C
By having the `submodule init` functionality in C, we can reference it
easier from other parts in the code in later patches. The code is split
up to have one function to initialize one submodule and a calling function
that takes care of the rest, such as argument handling and translating the
arguments to the paths of the submodules.

This is the first submodule subcommand that is fully converted to C
except for the usage string, so this is actually removing a call to
the `submodule--helper list` function, which is supposed to be used in
this transition. Instead we'll make a direct call to `module_list_compute`.

An explanation why we need to edit the prefixes in cmd_update in
git-submodule.sh in this patch:

By having no processing in the shell part, we need to convey the notion
of wt_prefix and prefix to the C parts, which former patches punted on
and did the processing of displaying path in the shell.

`wt_prefix` used to hold the path from the repository root to the current
directory, e.g. wt_prefix would be t/ if the user invoked the
`git submodule` command in ~/repo/t and ~repo is the GIT_DIR.

`prefix` used to hold the relative path from the repository root to the
operation, e.g. if you have recursive submodules, the shell script would
modify the `prefix` in each recursive step by adding the submodule path.

We will pass `wt_prefix` into the C helper via `git -C <dir>` as that
will setup git in the directory the user actually called git-submodule.sh
from. The `prefix` will be passed in via the `--prefix` option.

Having `prefix` and `wt_prefix` relative to the GIT_DIR of the
calling superproject is unfortunate with this patch as the C code doesn't
know about a possible recursion from a superproject via `submodule update
--init --recursive`.

To fix this, we change the meaning of `wt_prefix` to point to the current
project instead of the superproject and `prefix` to include any relative
paths issues in the superproject. That way `prefix` will become the leading
part for displaying paths and `wt_prefix` will be empty in recursive
calls for now.

The new notion of `wt_prefix` and `prefix` still allows us to reconstruct
the calling directory in the superproject by just traveling reverse of
`prefix`.

63e95beb08 submodule: port resolve_relative_url from shell to C
Later on we want to automatically call `git submodule init` from
other commands, such that the users don't have to initialize the
submodule themselves.  As these other commands are written in C
already, we'd need the init functionality in C, too.  The
`resolve_relative_url` function is a large part of that init
functionality, so start by porting this function to C.

To create the tests in t0060, the function `resolve_relative_url`
was temporarily enhanced to write all inputs and output to disk
when running the test suite. The added tests in this patch are
a small selection thereof.

40d71940b6 builtin/merge.c: fix a bug with trivial merges
If read_tree_trivial() succeeds and produces a tree that is already
in the object store, then the index is not written to disk, leaving
it out-of-sync with both HEAD and the working tree.

In order to write the index back out to disk after a merge,
write_index_locked() needs to be called.  For most merge strategies, this
is done from try_merge_strategy().  For fast forward updates, this is
done from checkout_fast_forward().  When trivial merges work, the call to
write_index_locked() is buried a little deeper:

  merge_trivial()
  -> write_tree_trivial()
     -> write_cache_as_tree()
        -> write_index_as_tree()
           -> write_locked_index()

However, it is only called when !cache_tree_fully_valid(), which is how
this bug is triggered.  But that also shows why this bug doesn't affect
any other merge strategies or cases.

Add a direct call to write_index_locked() from merge_trivial() to fix
this issue.  Since the indirect call to write_locked_index() was
conditional on cache_tree_fully_valid(), it won't be written twice.

27014cbc04 commit: do not ignore an empty message given by -m ''
When f9568530 (builtin-commit: resurrect behavior for multiple -m
options, 2007-11-11) converted a "char *message" to "struct strbuf
message" to hold the messages given with the "-m" option, it
incorrectly changed the checks "did we get a message with the -m
option?" to "is message.len 0?".  Later, we noticed one breakage
from this change and corrected it with 25206778 (commit: don't start
editor if empty message is given with -m, 2013-05-25).

However, "we got a message with -m, even though an empty one, so we
shouldn't be launching an editor" was not the only breakage.

 * "git commit --amend -m '' --allow-empty", even though it looks
   strange, is a valid request to amend the commit to have no
   message at all.  Due to the misdetection of the presence of -m on
   the command line, we ended up keeping the log messsage from the
   original commit.

 * "git commit -m "$msg" -F file" should be rejected whether $msg is
   an empty string or not, but due to the same bug, was not rejected
   when $msg is empty.

 * "git -c template=file -m "$msg"" should ignore the template even
   when $msg is empty, but it didn't and instead used the contents
   from the template file.

Correct these by checking have_option_m, which the earlier 25206778
introduced to fix the same bug.

d281b45d75 builtin/verify-tag.c: ignore SIGPIPE in gpg-interface
The verify_signed_buffer() function may trigger a SIGPIPE when the
GPG child process terminates early (due to a bad keyid, for example)
and Git tries to write to it afterwards.  Previously, ignoring
SIGPIPE was done in builtin/verify-tag.c to avoid this issue.

However, any other caller who wants to call verify_signed_buffer()
would have to do the same.

Use sigchain_push(SIGPIPE, SIG_IGN) in verify_signed_buffer(),
pretty much like in sign_buffer(), so that any caller is not
required to perform this task.

This will avoid possible mistakes by further developers using
verify_signed_buffer().

Since commit c4805393 (autocrlf: Make it work also for un-normalized

95c38fb0ed branch: fix shortening of non-remote symrefs
Commit aedcb7d (branch.c: use 'ref-filter' APIs, 2015-09-23)
adjusted the symref-printing code to look like this:

    if (item->symref) {
	    skip_prefix(item->symref, "refs/remotes/", &desc);
	    strbuf_addf(&out, " -> %s", desc);
    }

This has three bugs in it:

  1. It always skips past "refs/remotes/", instead of
     skipping past the prefix associated with the branch we
     are showing (so commonly we see "refs/remotes/" for the
     refs/remotes/origin/HEAD symref, but the previous code
     would skip "refs/heads/" when showing a symref it found
     in refs/heads/.

  2. If skip_prefix() does not match, it leaves "desc"
     untouched, and we show whatever happened to be in it
     (which is the refname from a call to skip_prefix()
     earlier in the function).

  3. If we do match with skip_prefix(), we stomp on the
     "desc" variable, which is later passed to
     add_verbose_info(). We probably want to retain the
     original refname there (though it likely doesn't matter
     in practice, since after all, one points to the other).

The fix to match the original code is fairly easy: record
the prefix to strip based on item->kind, and use it here.
However, since we already have a local variable named "prefix",
let's give the two prefixes verbose names so we don't
confuse them.

70999e9cec branch -m: update all per-worktree HEADs
When renaming a branch, currently only the HEAD of current working tree

This is the current behavior, /path/to/wt's HEAD is not updated:

  % git worktree list
  /path/to     2c3c5f2 [master]
  /path/to/wt  2c3c5f2 [oldname]

  % git worktree list

1ea4d9b7c8 submodule--helper: do not borrow absolute_path() result for too long
absolute_path() is designed to allow its callers to take a brief
peek of the result (typically, to be fed to functions like
strbuf_add() and relative_path() as a parameter) without having to
worry about freeing it, but the other side of the coin of that
memory model is that the caller shouldn't rely too much on the
result living forever--there may be a helper function the caller
subsequently calls that makes its own call to absolute_path(),
invalidating the earlier result.

Use xstrdup() to make our own copy, and free(3) it when we are done.

so parse_binary() can return -1, because that's what error() returns.

Also parse_binary_hunk() sets "status" to -1 in case of error and
parse_binary() does "if (status) return status;".

In this case parse_chunk() should not add -1 to the patchsize it computes.

c6777563cd git-send-pack: fix --all option when used with directory
When using git send-pack with --all option
and a target repository specification ([<host>:]<directory>),
usage message is being displayed instead of performing
the actual transmission.

The reason for this issue is that destination and refspecs are being set
in the same conditional and are populated from argv. When a target
repository is passed, refspecs is being populated as well with its value.
This makes the check for refspecs not being NULL to always return true,
which, in conjunction with the check for --all or --mirror options,
is always true as well and returns usage message instead of proceeding.

This ensures that send-pack will stop execution only when --all
or --mirror switch is used in conjunction with any refspecs passed.

e379fdf34f merge: refuse to create too cool a merge by default
While it makes sense to allow merging unrelated histories of two
projects that started independently into one, in the way "gitk" was
merged to "git" itself aka "the coolest merge ever", such a merge is
still an unusual event.	 Worse, if somebody creates an independent
history by starting from a tarball of an established project and
sends a pull request to the original project, "git merge" however
happily creates such a merge without any sign of something unusual
is happening.

Teach "git merge" to refuse to create such a merge by default,
unless the user passes a new "--allow-unrelated-histories" option to
tell it that the user is aware that two unrelated projects are
merged.

Because such a "two project merge" is a rare event, a configuration
option to always allow such a merge is not added.

We could add the same option to "git pull" and have it passed
through to underlying "git merge".  I do not have a fundamental
opposition against such a feature, but this commit does not do so
and instead leaves it as low-hanging fruit for others, because such
a "two project merge" would be done after fetching the other project
into some location in the working tree of an existing project and
making sure how well they fit together, it is sufficient to allow a
local merge without such an option pass-through from "git pull" to
"git merge".  Many tests that are updated by this patch does the
pass-through manually by turning:

	git pull something

into its equivalent:

	git fetch something &&
	git merge --allow-unrelated-histories FETCH_HEAD

If somebody is inclined to add such an option, updated tests in this
change need to be adjusted back to:

	git pull --allow-unrelated-histories something

This regression was introduced in 74703a1e4d (submodule: rewrite
`module_list` shell function in C, 2015-09-02), as we changed the
order of checking in new module listing to first check whether it is
a gitlin before feeding it to match_pathspec().  It used to be that
a pathspec that does not match any path were diagnosed as an error,
but the new code complains for a pathspec that does not match any
submodule path.

Arguably the new behaviour may give us a better diagnosis, but that
is inconsistent with the suggestion "deinit" gives, and also this
was an unintended accident.  The new behaviour hopefully can be
redesigned and implemented better in future releases, but for now,
switch these two checks to restore the same behavior as before.  In
an empty repository, giving the pathspec '.' will still get the same
"did not match" error, but that is the same bug we had before 1.7.0.

2824e1841b list-objects: pass full pathname to callbacks
When we find a blob at "a/b/c", we currently pass this to
our show_object_fn callbacks as two components: "a/b/" and
"c". Callbacks which want the full value then call
path_name(), which concatenates the two. But this is an
inefficient interface; the path is a strbuf, and we could
simply append "c" to it temporarily, then roll back the
length, without creating a new copy.

So we could improve this by teaching the callsites of
path_name() this trick (and there are only 3). But we can
also notice that no callback actually cares about the
broken-down representation, and simply pass each callback
the full path "a/b/c" as a string. The callback code becomes
even simpler, then, as we do not have to worry about freeing
an allocated buffer, nor rolling back our modification to
the strbuf.

This is theoretically less efficient, as some callbacks
would not bother to format the final path component. But in
practice this is not measurable. Since we use the same
strbuf over and over, our work to grow it is amortized, and
we really only pay to memcpy a few bytes.

dc06dc8800 list-objects: drop name_path entirely
In the previous commit, we left name_path as a thin wrapper
around a strbuf. This patch drops it entirely. As a result,
every show_object_fn callback needs to be adjusted. However,
none of their code needs to be changed at all, because the
only use was to pass it to path_name(), which now handles
the bare strbuf.

85975c0c7f grep: turn off gitlink detection for --no-index
If we are running "git grep --no-index" outside of a git
repository, we behave roughly like "grep -r", examining all
files in the current directory and its subdirectories.
However, because we use fill_directory() to do the
recursion, it will skip over any directories which look like
sub-repositories.

For a normal git operation (like "git grep" in a repository)
this makes sense; we do not want to cross the boundary out
of our current repository into a submodule. But for
"--no-index" without a repository, we should look at all
files, including embedded repositories.

There is one exception, though: we probably should _not_
descend into ".git" directories. Doing so is inefficient and
unlikely to turn up useful hits.

This patch drops our use of dir.c's gitlink-detection, but
we do still avoid ".git". That makes us more like tools such
as "ack" or "ag", which also know to avoid cruft in .git.

As a bonus, this also drops our usage of the ref code
when we are outside of a repository, making the transition
to pluggable ref backends cleaner.

f1c126bd8b setup: set startup_info->have_repository more reliably
When setup_git_directory() is called, we set a flag in
startup_info to indicate we have a repository. But there are
a few other mechanisms by which we might set up a repo:

  1. When creating a new repository via init_db(), we
     transition from no-repo to being in a repo. We should
     tweak this flag at that moment.

  2. In enter_repo(), a stricter form of
     setup_git_directory() used by server-side programs, we
     check the repository format config. After doing so, we
     know we're in a repository, and can set the flag.

With these changes, library code can now reliably tell
whether we are in a repository and act accordingly. We'll
leave the "prefix" field as NULL, which is what happens when
setup_git_directory() finds there is no prefix.

As we create the .keep file with O_CREAT|O_EXCL, and we do so after
we write the .idx file, we luckily do not clobber the .idx file, but
because we deliberately ignored EEXIST when creating .keep file
(which is justifiable because only the existence of .keep file
matters), nobody noticed this mistake so far.

14111fc492 git: submodule honor -c credential.* from command line
Due to the way that the git-submodule code works, it clears all local
git environment variables before entering submodules. This is normally
a good thing since we want to clear settings such as GIT_WORKTREE and
other variables which would affect the operation of submodule commands.
However, GIT_CONFIG_PARAMETERS is special, and we actually do want to
preserve these settings. However, we do not want to preserve all
configuration as many things should be left specific to the parent
project.

Add a git submodule--helper function, sanitize-config, which shall be
used to sanitize GIT_CONFIG_PARAMETERS, removing all key/value pairs
except a small subset that are known to be safe and necessary.

Replace all the calls to clear_local_git_env with a wrapped function
that filters GIT_CONFIG_PARAMETERS using the new helper and then
restores it to the filtered subset after clearing the rest of the
environment.

fc7d47f0dd rev-parse: let some options run outside repository
Once upon a time, you could use "--local-env-vars" and
"--resolve-git-dir" outside of any git repository, but they
had to come first on the command line. Commit 68889b4
(rev-parse: remove restrictions on some options, 2013-07-21)
put them into the normal option-parsing loop, fixing the
latter. But it inadvertently broke the former, as we call
setup_git_directory() before starting that loop.

We can note that those options don't care even conditionally
about whether we are in a git repo. So it's fine if we
simply wait to setup the repo until we see an option that
needs it.

However, there is one special exception we should make:
historically, rev-parse will set up the repository and read
config even if there are _no_ options. Some of the
tests in t1300 rely on this to check "git -c $config"
parsing. That's not mirroring real-world use, and we could
tweak the test.  But t0002 uses a bare "git rev-parse" to
check "are we in a git repository?". It's plausible that
real-world scripts are relying on this.

So let's cover this case specially, and treat an option-less
"rev-parse" as "see if we're in a repo".

47fe3f6ef0 nth_packed_object_offset: bounds-check extended offset
If a pack .idx file has a corrupted offset for an object, we
may try to access an offset in the .idx or .pack file that
is larger than the file's size.  For the .pack case, we have
use_pack() to protect us, which realizes the access is out
of bounds. But if the corrupted value asks us to look in the
.idx file's secondary 64-bit offset table, we blindly add it
to the mmap'd index data and access arbitrary memory.

We can fix this with a simple bounds-check compared to the
size we found when we opened the .idx file.

Note that there's similar code in index-pack that is
triggered only during "index-pack --verify". To support
both, we pull the bounds-check into a separate function,
which dies when it sees a corrupted file.

It would be nice if we could return an error, so that the
pack code could try to find a good copy of the object
elsewhere. Currently nth_packed_object_offset doesn't have
any way to return an error, but it could probably use "0" as
a sentinel value (since no object can start there). This is
the minimal fix, and we can improve the resilience later on
top.

5404c116aa diff: activate diff.renames by default
Rename detection is a very convenient feature, and new users shouldn't
have to dig in the documentation to benefit from it.

Potential objections to activating rename detection are that it
sometimes fail, and it is sometimes slow. But rename detection is
already activated by default in several cases like "git status" and "git
merge", so activating diff.renames does not fundamentally change the
situation. When the rename detection fails, it now fails consistently
between "git diff" and "git status".

This setting does not affect plumbing commands, hence well-written
scripts will not be affected.

2f275207ce push: remove "push.default is unset" warning message
The warning was important before the 2.0 transition, and remained
important for a while after, so that new users get push.default
explicitly in their configuration and do not experience inconsistent
behavior if they ever used an older version of Git.

The warning has been there since version 1.8.0 (Oct 2012), hence we can
expect the vast majority of current Git users to have been exposed to
it, and most of them have already set push.default explicitly. The
switch from 'matching' to 'simple' was planned for 2.0 (May 2014), but
actually happened only for 2.3 (Feb 2015).

Today, the warning is mostly seen by beginners, who have not set their
push.default configuration (yet). For many of them, the warning is
confusing because it talks about concepts that they have not learned and
asks them a choice that they are not able to make yet. See for example

  http://stackoverflow.com/questions/13148066/warning-push-default-is-unset-its-implicit-value-is-changing-in-git-2-0

(1260 votes for the question, 1824 for the answer as of writing)

Remove the warning completely to avoid disturbing beginners. People who
still occasionally use an older version of Git will be exposed to the
warning through this old version.

Eventually, versions of Git without the warning will be deployed enough
and tutorials will not need to advise setting push.default anymore.

5545f057d4 fetch-pack: simplify add_sought_entry
We have two variants of this function, one that takes a
string and one that takes a ptr/len combo. But we only call
the latter with the length of a NUL-terminated string, so
our first simplification is to drop it in favor of the
string variant.

Since we know we have a string, we can also replace the
manual memory computation with a call to alloc_ref().

Furthermore, we can rely on get_oid_hex() to complain if it
hits the end of the string. That means we can simplify the
check for "<sha1> <ref>" versus just "<ref>". Rather than
manage the ptr/len pair, we can just bump the start of our
string forward. The original code over-allocated based on
the original "namelen" (which wasn't _wrong_, but was simply
wasteful and confusing).

50a6c8efa2 use st_add and st_mult for allocation size computation
If our size computation overflows size_t, we may allocate a
much smaller buffer than we expected and overflow it. It's
probably impossible to trigger an overflow in most of these
sites in practice, but it is easy enough convert their
additions and multiplications into overflow-checking
variants. This may be fixing real bugs, and it makes
auditing the code easier.

3733e69464 use xmallocz to avoid size arithmetic
We frequently allocate strings as xmalloc(len + 1), where
the extra 1 is for the NUL terminator. This can be done more
simply with xmallocz, which also checks for integer
overflow.

There's no case where switching xmalloc(n+1) to xmallocz(n)
is wrong; the result is the same length, and malloc made no
guarantees about what was in the buffer anyway. But in some
cases, we can stop manually placing NUL at the end of the
allocated buffer. But that's only safe if it's clear that
the contents will always fill the buffer.

In each case where this patch does so, I manually examined
the control flow, and I tried to err on the side of caution.

b32fa95fd8 convert trivial cases to ALLOC_ARRAY
Each of these cases can be converted to use ALLOC_ARRAY or
REALLOC_ARRAY, which has two advantages:

  1. It automatically checks the array-size multiplication
     for overflow.

  2. It always uses sizeof(*array) for the element-size,
     so that it can never go out of sync with the declared
     type of the array.

850d2fec53 convert manual allocations to argv_array
There are many manual argv allocations that predate the
argv_array API. Switching to that API brings a few
advantages:

  1. We no longer have to manually compute the correct final
     array size (so it's one less thing we can screw up).

  2. In many cases we had to make a separate pass to count,
     then allocate, then fill in the array. Now we can do it
     in one pass, making the code shorter and easier to
     follow.

  3. argv_array handles memory ownership for us, making it
     more obvious when things should be free()d and and when
     not.

Most of these cases are pretty straightforward. In some, we
switch from "run_command_v" to "run_command" which lets us
directly use the argv_array embedded in "struct
child_process".

30598ad06f config: rename git_config_set to git_config_set_gently
The desired default behavior for `git_config_set` is to die
whenever an error occurs. Dying is the default for a lot of
internal functions when failures occur and is in this case the
right thing to do for most callers as otherwise we might run into
inconsistent repositories without noticing.

As some code may rely on the actual return values for
`git_config_set` we still require the ability to invoke these
functions without aborting. Rename the existing `git_config_set`
functions to `git_config_set_gently` to keep them available for
those callers.
