9dd330e6ca rerere: release lockfile in non-writing functions
There's a bug in builtin/am.c in which we take a lock on
MERGE_RR recursively. But rather than fix am.c, this patch
fixes the confusing interface from rerere.c that caused the
bug. Read on for the gory details.

The setup_rerere() function both reads the existing MERGE_RR
file, and takes MERGE_RR.lock. In the rerere() and
rerere_forget() functions, we end up in write_rr(), which
will then commit the lock file.

But for functions like rerere_clear() that do not write to
MERGE_RR, we expect the caller to have handled
setup_rerere(). That caller would then need to release the
lockfile, but it can't; the lock struct is local to
rerere.c.

For builtin/rerere.c, this is OK. We run a single rerere
operation and then exit immediately, which has the side
effect of rolling back the lockfile.

But in builtin/am.c, this is actively wrong. If we run "git
am -3 --skip", we call setup-rerere twice without releasing
the lock:

  1. The "--skip" causes us to call am_rerere_clear(), which
     calls setup_rerere(), but never drops the lock.

  2. We then proceed to the next patch.

  3. The "--3way" may cause us to call rerere() to handle
     conflicts in that patch, but we are already holding the
     lock. The lockfile code dies with:

     BUG: prepare_tempfile_object called for active object

We could fix this by having rerere_clear() call
rollback_lock_file(). But it feels a bit odd for it to roll
back a lockfile that it did not itself take. So let's
simplify the interface further, and handle setup_rerere in
the function itself, taking away the question from the
caller over whether they need to do so.

We can give rerere_gc() the same treatment, as well (even
though it doesn't have any callers besides builtin/rerere.c
at this point). Note that these functions don't take flags
from their callers to pass along to setup_rerere; that's OK,
because the flags would not be meaningful for what they are
doing.

Both of those functions need to hold the lock because even
though they do not write to MERGE_RR, they are still writing
and should be protected from a simultaneous "rerere" run.
But rerere_remaining(), "rerere diff", and "rerere status"
are all read-only operations. They want to setup_rerere(),
but do not care about taking the lock in the first place.
Since our update of MERGE_RR is the usual atomic rename done
by commit_lock_file, they can just do a lockless read. For
that, we teach setup_rerere a READONLY flag to avoid the
lock.

As a bonus, this pushes builtin/rerere.c's setup_rerere call
closer to the functions that use it. Which means that "git
rerere totally-bogus-command" will no longer silently
exit(0) in a repository without rerere enabled.

5c99995df8 trailer: support multiline title
We currently ignore the first line passed to `git interpret-trailers`,
when looking for the beginning of the trailers.

Unfortunately this does not work well when a commit is created with a
line break in the title, using for example the following command:

git commit -m 'place of
code: change we made'

That's why instead of ignoring only the first line, it is better to
ignore the first paragraph.

ce11360467 log: diagnose empty HEAD more clearly
If you init or clone an empty repository, the initial
message from running "git log" is not very friendly:

  $ git init
  Initialized empty Git repository in /home/peff/foo/.git/
  $ git log
  fatal: bad default revision 'HEAD'

Let's detect this situation and write a more friendly
message:

  $ git log
  fatal: your current branch 'master' does not have any commits yet

We also detect the case that 'HEAD' points to a broken ref;
this should be even less common, but is easy to see. Note
that we do not diagnose all possible cases. We rely on
resolve_ref, which means we do not get information about
complex cases. E.g., "--default master" would use dwim_ref
to find "refs/heads/master", but we notice only that
"master" does not exist. Similarly, a complex sha1
expression like "--default HEAD^2" will not resolve as a
ref.

But that's OK. We fall back to a generic error message in
those cases, and they are unlikely to be used anyway.
Catching an empty or broken "HEAD" improves the common case,
and the other cases are not regressed.

475a34451f commit: don't rewrite shared index unnecessarily
Remove a cache invalidation which would cause the shared index to be
rewritten on as-is commits.

When the cache-tree has changed, we need to update it.  But we don't
necessarily need to update the shared index.  So setting
active_cache_changed to SOMETHING_CHANGED is unnecessary.  Instead, we
let update_main_cache_tree just update the CACHE_TREE_CHANGED bit.

In order to test this, make test-dump-split-index not segfault on
missing replace_bitmap/delete_bitmap.  This new codepath is not called
now that the test passes, but is necessary to avoid a segfault when the
new test is run with the old builtin/commit.c code.

b43702ac56 git-p4: fix P4 label import for unprocessed commits
With --detect-labels enabled, git-p4 will try to create tags
using git fast-import by writing a "tag" clause to the
fast-import stream.

If the commit that the tag references has not yet actually
been processed by fast-import, then the tag can't be created
and git-p4 fails to import the P4 label.

Teach git-p4 to use fast-import "marks" when creating tags
which reference commits created during the current run of the
program.

Commits created before the current run are still referenced
in the old way using a normal git commit.

a0a50d873c git-p4: honor core.ignorecase when using P4 client specs
Perforce depot may record paths in mixed cases, e.g. "p4 files" may
show that there are these two paths:

   //depot/Path/to/file1
   //depot/pATH/to/file2

and with "p4" or "p4v", these end up in the same directory, e.g.

   //depot/Path/to/file1
   //depot/Path/to/file2

which is the desired outcome on case insensitive systems.

If git-p4 is used with client spec "//depot/Path/...", however, then
all files not matching the case in the client spec are ignored (in
the example above "//depot/pATH/to/file2").

Fix this by using the path case that appears first in lexicographical
order when core.ignorecase is set to true. This behavior is consistent
with "p4" and "p4v".

88329ca809 archive-zip: support more than 65535 entries
Support more than 65535 entries cleanly by writing a "zip64 end of
central directory record" (with a 64-bit field for the number of
entries) before the usual "end of central directory record" (which
contains only a 16-bit field).  InfoZIP's zip does the same.
Archives with 65535 or less entries are not affected.

Programs that extract all files like InfoZIP's zip and 7-Zip
ignored the field and could extract all files already.  Software
that relies on the ZIP file directory to show a list of contained
files quickly to simulate to normal directory like Windows'
built-in ZIP functionality only saw a subset of the included files.

Windows supports ZIP64 since Vista according to
https://en.wikipedia.org/wiki/Zip_%28file_format%29#ZIP64.

19ee29401d t5004: test ZIP archives with many entries
A ZIP file directory has a 16-bit field for the number of entries it
contains.  There are 64-bit extensions to deal with that.  Demonstrate
that git archive --format=zip currently doesn't use them and instead
overflows the field.

InfoZIP's unzip doesn't care about this field and extracts all files
anyway.  Software that uses the directory for presenting a filesystem
like view quickly -- notably Windows -- depends on it, but doesn't
lend itself to an automatic test case easily.  Use InfoZIP's zipinfo,
which probably isn't available everywhere but at least can provides
*some* way to check this field.

To speed things up a bit create and commit only a subset of the files
and build a fake tree out of duplicates and pass that to git archive.

2bd07065c3 describe --contains: default to HEAD when no commit-ish is given
'git describe --contains' doesn't default to HEAD when no commit is
given, and it doesn't produce any output, not even an error:

  ~/src/git ((v2.5.0))$ ./git describe --contains
  ~/src/git ((v2.5.0))$ ./git describe --contains HEAD
  v2.5.0^0

Unlike other 'git describe' options, the '--contains' code path is
implemented by calling 'name-rev' with a bunch of options plus all the
commit-ishes that were passed to 'git describe'.  If no commit-ish was
present, then 'name-rev' got invoked with none, which then leads to the
behavior illustrated above.

Porcelain commands usually default to HEAD when no commit-ish is given,
and 'git describe' already does so in all other cases, so it should do
so with '--contains' as well.

Pass HEAD to 'name-rev' when no commit-ish is given on the command line
to make '--contains' behave consistently with other 'git describe'
options.  While at it, use argv_array_pushv() instead of the loop to
pass commit-ishes to 'git name-rev'.

'git describe's short help already indicates that the commit-ish is
optional, but the synopsis in the man page doesn't, so update it
accordingly as well.

  git: 'foo_bar' is not a git command. See 'git --help'.

You cannot name an alias with an underscore. And if you have
an external command with one, you cannot configure its
pager.

In the long run, we may develop a different config scheme
for these features. But in the near term (and because we'll
need to support the existing scheme indefinitely), we should
at least squelch the error messages shown above.

These errors come from git_config_parse_key. Ideally we
would pass a "quiet" flag to the config machinery, but there
are many layers between the pager code and the key parsing.
Passing a flag through all of those would be an invasive
change.

Instead, let's provide a config function to report on
whether a key is syntactically valid, and have the pager and
alias code skip lookup for bogus keys. We can build this
easily around the existing git_config_parse_key, with two
minor modifications:

  1. We now handle a NULL store_key, to validate but not
     write out the normalized key.

  2. We accept a "quiet" flag to avoid writing to stderr.
     This doesn't need to be a full-blown public "flags"
     field, because we can make the existing implementation
     a static helper function, keeping the mess contained
     inside config.c.

dc5d553b55 trailer: ignore first line of message
When looking for the start of the trailers in the message
we are passed, we should ignore the first line of the message.

The reason is that if we are passed a patch or commit message
then the first line should be the patch title.
If we are passed only trailers we can expect that they start
with an empty line that can be ignored too.

This way we can properly process commit messages that have
only one line with something that looks like a trailer, for
example like "area of code: change we made".

959b5455d0 submodule: implement a config API for lookup of .gitmodules values
In a superproject some commands need to interact with submodules. They
need to query values from the .gitmodules file either from the worktree
of from certain revisions. At the moment this is quite hard since a
caller would need to read the .gitmodules file from the history and then
parse the values. We want to provide an API for this so we have one
place to get values from .gitmodules from any revision (including the
worktree).

The API is realized as a cache which allows us to lazily read
.gitmodules configurations by commit into a runtime cache which can then
be used to easily lookup values from it. Currently only the values for
path or name are stored but it can be extended for any value needed.

It is expected that .gitmodules files do not change often between
commits. Thats why we lookup the .gitmodules sha1 from a commit and then
either lookup an already parsed configuration or parse and cache an
unknown one for each sha1. The cache is lazily build on demand for each
requested commit.

This cache can be used for all purposes which need knowledge about
submodule configurations. Example use cases are:

 * Recursive submodule checkout needs to lookup a submodule name from
   its path when a submodule first appears. This needs be done before
   this configuration exists in the worktree.

 * The implementation of submodule support for 'git archive' needs to
   lookup the submodule name to generate the archive when given a
   revision that is not checked out.

 * 'git fetch' when given the --recurse-submodules=on-demand option (or
   configuration) needs to lookup submodule names by path from the
   database rather than reading from the worktree. For new submodule it
   needs to lookup the name from its path to allow cloning new
   submodules into the .git folder so they can be checked out without
   any network interaction when the user does a checkout of that
   revision.

3ecc7040ef am --skip/--abort: merge HEAD/ORIG_HEAD tree into index
After running "git am --abort", and then running "git reset --hard",
files that were not modified would still be re-checked out.

This is because clean_index() in builtin/am.c mistakenly called the
read_tree() function, which overwrites all entries in the index,
including the stat info.

"git am --skip" did not seem to have this issue because am_skip() called
am_run(), which called refresh_cache() to update the stat info. However,
there's still a performance penalty as the lack of stat info meant that
refresh_cache() would have to scan all files for changes.

Fix this by using unpack_trees() instead to merge the tree into the
index, so that the stat info from the index is kept.

73f9145fbf untracked cache: fix entry invalidation
First, the current code in untracked_cache_invalidate_path() is wrong
because it can only handle paths "a" or "a/b", not "a/b/c" because
lookup_untracked() only looks for entries directly under the given
directory. In the last case, it will look for the entry "b/c" in
directory "a" instead. This means if you delete or add an entry in a
subdirectory, untracked cache may become out of date because it does not
invalidate properly. This is noticed by David Turner.

The second problem is about invalidation inside a fully untracked/excluded
directory. In this case we may have to invalidate back to root. See the
comment block for detail.

2e5910f276 untracked-cache: fix subdirectory handling
Previously, some calls lookup_untracked would pass a full path.  But
lookup_untracked assumes that the portion of the path up to and
including to the untracked_cache_dir has been removed.  So
lookup_untracked would be looking in the untracked_cache for 'foo' for
'foo/bar' (instead of just looking for 'bar').  This would cause
untracked cache corruption.

Instead, treat_directory learns to track the base length of the parent
directory, so that only the last path component is passed to
lookup_untracked.

Teach notes about a new "notes.<name>.mergeStrategy" option for
configuring the notes merge strategy when merging into
refs/notes/<name>. This option allows for the selection of merge
strategy for particular notes refs, rather than all notes ref merges, as
user may not want cat_sort_uniq for all refs, but only some. Note that
the <name> is the local reference we are merging into, not the remote
ref we merged from. The assumption is that users will mostly want to
configure separate local ref merge strategies rather than strategies
depending on which remote ref they merge from.

b5e823594c am: let --signoff override --no-signoff
After resolving a conflicting patch, a user may wish to sign off the
patch to declare that the patch has been modified. As such, the user
will expect that running "git am --signoff --continue" will append the
signoff to the commit message.

However, the --signoff option is only taken into account during the
mail-parsing stage. If the --signoff option is set, then the signoff
will be appended to the commit message. Since the mail-parsing stage
comes before the patch application stage, the --signoff option, if
provided on the command-line when resuming, will have no effect at all.

We cannot move the append_signoff() call to the patch application stage
as the applypatch-msg hook and interactive mode, which run before patch
application, may expect the signoff to be there.

Fix this by taking note if the user explictly set the --signoff option
on the command-line, and append the signoff to the commit message when
resuming if so.

852a171018 am: let command-line options override saved options
When resuming, git-am mistakenly ignores command-line options.

For instance, when a patch fails to apply with "git am patch",
subsequently running "git am --3way" would not cause git-am to fall
back on attempting a threeway merge.  This occurs because by default
the --3way option is saved as "false", and the saved am options are
loaded after the command-line options are parsed, thus overwriting
the command-line options when resuming.

Fix this by moving the am_load() function call before parse_options(),
so that command-line options will override the saved am options.

The purpose of supporting this use case is to enable users to "wiggle"
that one conflicting patch. As such, it is expected that the
command-line options do not affect subsequent applied patches. Implement
this by calling am_load() once we apply the conflicting patch
successfully.

18d8c26930 test_terminal: redirect child process' stdin to a pty
When resuming, git-am detects if we are trying to feed it patches or not
by checking if stdin is a TTY.

However, the test library redirects stdin to /dev/null. This makes it
difficult, for instance, to test the behavior of "git am -3" when
resuming, as git-am will think we are trying to feed it patches and
error out.

Support this use case by extending test-terminal.perl to create a
pseudo-tty for the child process' standard input as well.

Note that due to the way the code is structured, the child's stdin
pseudo-tty will be closed when we finish reading from our stdin. This
means that in the common case, where our stdin is attached to /dev/null,
the child's stdin pseudo-tty will be closed immediately. Some operations
like isatty(), which git-am uses, require the file descriptor to be
open, and hence if the success of the command depends on such functions,
test_terminal's stdin should be redirected to a source with large amount
of data to ensure that the child's stdin is not closed, e.g.

	test_terminal git am --3way </dev/zero

77b9b1d13a add_to_alternates_file: don't add duplicate entries
The add_to_alternates_file function blindly uses
hold_lock_file_for_append to copy the existing contents, and
then adds the new line to it. This has two minor problems:

  1. We might add duplicate entries, which are ugly and
     inefficient.

  2. We do not check that the file ends with a newline, in
     which case we would bogusly append to the final line.
     This is quite unlikely in practice, though, as we call
     this function only from git-clone, so presumably we are
     the only writers of the file (and we always add a
     newline).

Instead of using hold_lock_file_for_append, let's copy the
file line by line, which ensures all records are properly
terminated. If we see an extra line, we can simply abort the
update (there is no point in even copying the rest, as we
know that it would be identical to the original).

As a bonus, we also get rid of some calls to the
static-buffer mkpath and git_path functions.

bc192300c4 t5700: modernize style
The early part of this test is rather old, and does not
follow our usual style guidelines. In particular:

  - the tests liberally chdir, and expect out-of-test "cd"
    commands to return them to a sane state

  - test commands aren't indented at all

  - there are a lot of minor formatting nits, like the
    opening quote of the test block on the wrong line,
    spaces after ">", etc

This patch fixes the style issues, and uses a few helper
functions, along with subshells and "git -C", to avoid
changing the cwd of the main script.

92722efec0 clone: do not use port number as dir name
If the URI contains a port number and the URI's path component is
empty we fail to guess a sensible directory name. E.g. cloning a
repository 'ssh://example.com:2222/' we guess a directory name
'2222' where we would want the hostname only, e.g. 'example.com'.

We need to take care to not drop trailing port-like numbers in
certain cases. E.g. when cloning a repository 'foo/bar:2222.git'
we want to guess the directory name '2222' instead of 'bar'.
Thus, we have to first check the stripped URI for path separators
and only strip port numbers if there are path separators present.
This heuristic breaks when cloning a repository 'bar:2222.git',
though.

e895986727 clone: do not include authentication data in guessed dir
If the URI contains authentication data and the URI's path
component is empty, we fail to guess a sensible directory name.
E.g. cloning a repository 'ssh://user:password@example.com/' we
guess a directory name 'password@example.com' where we would want
the hostname only, e.g. 'example.com'.

The naive way of just adding '@' as a path separator would break
cloning repositories like 'foo/bar@baz.git' (which would
currently become 'bar@baz' but would then become 'baz' only).
Instead fix this by first dropping the scheme and then greedily
scanning for an '@' sign until we find the first path separator.

db2e220447 clone: use computed length in guess_dir_name
Commit 7e837c6 (clone: simplify string handling in
guess_dir_name(), 2015-07-09) changed clone to use
strip_suffix instead of hand-rolled pointer manipulation.
However, strip_suffix will strip from the end of a
NUL-terminated string, and we may have already stripped some
characters (like directory separators, or "/.git"). This
leads to commands like:

  git clone host:foo.git/

failing to strip the ".git".

We must instead convert our pointer arithmetic into a
computed length and feed that to strip_suffix_mem, which will
then reduce the length further for us.

It would be nicer if we could drop the pointer manipulation
entirely, and just continually strip using strip_suffix. But
that doesn't quite work for two reasons:

  1. The early suffixes we're stripping are not constant; we
     need to look for is_dir_sep, which could be one of
     several characters.

  2. Mid-way through the stripping we compute the pointer
     "start", which shows us the beginning of the pathname.
     Which really give us two lengths to work with: the
     offset from the start of the string, and from the start
     of the path. By using pointers for the early part, we
     can just compute the length from "start" when we need
     it.

d6a31e08cd clone: add tests for output directory
When we run "git clone $url", clone guesses from the $url
what to name the local output directory. We don't have any
test coverage of this, so let's add some basic tests.

This reveals a few problems:

  - cloning "foo.git/" does not properly remove the ".git";
    this is a recent regression from 7e837c6 (clone:
    simplify string handling in guess_dir_name(), 2015-07-09)

  - likewise, cloning foo/.git does not seem to handle the
    bare case (we should end up in foo.git, but we try to
    use foo/.git on the local end), which also comes from
    7e837c6.

  - cloning the root is not very smart about URL parsing,
    and usernames and port numbers may end up in the
    directory name

All of these tests are marked as failures.

578625fa91 config: add '--name-only' option to list only variable names
'git config' can only show values or name-value pairs, so if a shell
script needs the names of set config variables it has to run 'git config
--list' or '--get-regexp' and parse the output to separate config
variable names from their values.  However, such a parsing can't cope
with multi-line values.  Though 'git config' can produce null-terminated
output for newline-safe parsing, that's of no use in such a case, becase
shells can't cope with null characters.

Even our own bash completion script suffers from these issues.

Help the completion script, and shell scripts in general, by introducing
the '--name-only' option to modify the output of '--list' and
'--get-regexp' to list only the names of config variables, so they don't
have to perform error-prone post processing to separate variable names
from their values anymore.

9b5fe78b34 test-lib: disable trace when test is not verbose
The "-x" test-script option turns on the shell's "-x"
tracing, which can help show why a particular test is
failing. Unfortunately, this can create false negatives in
some tests if they invoke a shell function with its stderr
redirected. t5512.10 is such a test, as it does:

    test_must_fail git ls-remote refs*master >actual 2>&1 &&
    test_cmp exp actual

The "actual" file gets the "-x" trace for the test_must_fail
function, which prevents it from matching the expected
output.

There's no way to avoid this without managing the
trace flag inside each sub-function, which isn't really a
workable solution. But unless you specifically care about
t5512.10, we can work around it by enabling tracing only for
the specific tests we want.

You can already do:

    ./t5512-ls-remote.sh -x --verbose-only=16

to see the trace only for a specific test. But that doesn't
_disable_ the tracing in the other tests; it just sends it
to /dev/null. However, there's no point in generating a
trace that the user won't see, so we can simply disable
tracing whenever it doesn't have a matching verbose flag.

The normal case of just "./t5512-ls-remote.sh -x" stays the
same, as "-x" already implies "--verbose" (and
"--verbose-only" overrides "--verbose", which is why this
works at all). And for our test, we need only check
$verbose, as maybe_setup_verbose will have already
set that flag based on the $verbose_only list).

2a01ef8ca3 test-lib: turn off "-x" tracing during chain-lint check
Now that GIT_TEST_CHAIN_LINT is on by default, running:

    ./t0000-basic.sh -x --verbose-only=1

starts with:

    expecting success:
            find .git/objects -type f -print >should-be-empty &&
            test_line_count = 0 should-be-empty

    + exit 117
    error: last command exited with $?=117
    + find .git/objects -type f -print
    + test_line_count = 0 should-be-empty
    + test 3 != 3
    + wc -l
    + test 0 = 0
    ok 1 - .git/objects should be empty after git init in an empty repo

This is confusing, as the "exit 117" line and the error line
(which is printed in red, no less!) are not part of the test
at all, but are rather in the separate chain-lint test_eval.
Let's unset the "trace" variable when eval-ing the chain
lint check, which avoids this.

Note that we cannot just do a one-shot variable like:

    trace= test_eval ...

as the behavior of one-shot variables for function calls
is not portable.

2bc31d1631 refs: support negative transfer.hideRefs
If you hide a hierarchy of refs using the transfer.hideRefs
config, there is no way to later override that config to
"unhide" it. This patch implements a "negative" hide which
causes matches to immediately be marked as unhidden, even if
another match would hide it. We take care to apply the
matches in reverse-order from how they are fed to us by the
config machinery, as that lets our usual "last one wins"
config precedence work (and entries in .git/config, for
example, will override /etc/gitconfig).

So you can now do:

  $ git config --system transfer.hideRefs refs/secret
  $ git config transfer.hideRefs '!refs/secret/not-so-secret'

to hide refs/secret in all repos, except for one public bit
in one specific repo. Or you can even do:

  $ git clone \
      -u "git -c transfer.hiderefs="!refs/foo" upload-pack" \
      remote:repo.git

to clone remote:repo.git, overriding any hiding it has
configured.

There are two alternatives that were considered and
rejected:

  1. A generic config mechanism for removing an item from a
     list. E.g.: (e.g., "[transfer] hideRefs -= refs/foo").

     This is nice because it could apply to other
     multi-valued config, as well. But it is not nearly as
     flexible. There is no way to say:

       [transfer]
       hideRefs = refs/secret
       hideRefs = refs/secret/not-so-secret

     Having explicit negative specifications means we can
     override previous entries, even if they are not the
     same literal string.

  2. Adding another variable to override some parts of
     hideRefs (e.g., "exposeRefs").

     This solves the problem from alternative (1), but it
     cannot easily obey the normal config precedence,
     because it would use two separate lists. For example:

       [transfer]
       hideRefs = refs/secret
       exposeRefs = refs/secret/not-so-secret
       hideRefs = refs/secret/not-so-secret/no-really-its-secret

     With two lists, we have to apply the "expose" rules
     first, and only then apply the "hide" rules. But that
     does not match what the above config intends.

     Of course we could internally parse that to a single
     list, respecting the ordering, which saves us having to
     invent the new "!" syntax. But using a single name
     communicates to the user that the ordering _is_
     important. And "!" is well-known for negation, and
     should not appear at the beginning of a ref (it is
     actually valid in a ref-name, but all entries here
     should be fully-qualified, starting with "refs/").
