ce026cc7e2 t5528: do not fail with FreeBSD shell
The FreeBSD shell converts this expression:

  git ${1:+-c push.default="$1"} push

to this when "$1" is not empty:

  git "-c push.default=$1" push

which causes git to fail.  To avoid this we simply break up the
expansion into two parts so that the whitespace which creates
two arguments instead of one is outside the ${...} like so:

  git ${1:+-c} ${1:+push.default="$1"} push

This has the desired effect on all platforms allowing the test
to pass on FreeBSD.

51ff0f27bc log: decorate HEAD with branch name
Currently, log decorations do not indicate which branch is checked out
and whether HEAD is detached.

When branch foo is checked out, change the "HEAD, foo" part of the
decorations to "HEAD -> foo". This serves to indicate both ref
decorations (helped by the spacing) as well as their relationshsip.
As a consequence, "HEAD" without any " -> " denotes a detached HEAD now.

6a536e2076 git: treat "git -C '<path>'" as a no-op when <path> is empty
'git -C ""' unhelpfully dies with error "Cannot change to ''",
whereas the shell treats `cd ""' as a no-op.  Taking the shell's

28c8cfc363 rebase-interactive: suppress whitespace preceding item count
97f05f43 (Show number of TODO items for interactive rebase, 2014-12-10)
taught rebase-interactive to compute an item count with 'wc -l' and
display it in the instruction list comments:

    # Rebase 46640c6..5568fd5 onto 46640c6 (4 TODO item(s))

On Mac OS X, however, it renders as:

    # Rebase 46640c6..5568fd5 onto 46640c6 (       4 TODO item(s))

since 'wc -l' indents its output with leading spaces. Fix this.

4b06318664 branch: name detached HEAD analogous to status
"git status" carefully names a detached HEAD "at" resp. "from" a rev or
ref depending on whether the detached HEAD has moved since. "git branch"
always uses "from", which can be confusing, because a status-aware user
would interpret this as moved detached HEAD.

Make "git branch" use the same logic and wording.

17d65f03e1 sequencer: preserve commit messages
sequencer calls "commit" with default options, which implies
"--cleanup=default" unless the user specified something else in their
config. This leads to cherry-picked commits getting a cleaned up commit
message, which is usually not an intended side-effect.

Make the sequencer use "--cleanup=verbatim" so that it preserves commit
messages independent of the default, unless the user has set config for "commit"
or the message is amended with -s or -x.

4055500093 commit/status: show the index-worktree diff with -v -v
git commit and git status in long format show the diff between HEAD
and the index when given -v. This allows previewing a commit to be made.

They also list tracked files with unstaged changes, but without a diff.

Introduce '-v -v' which shows the diff between the index and the
worktree in addition to the HEAD index diff. This allows a review of unstaged
changes which might be missing from the commit.

In the case of '-v -v', additonal header lines

Changes to be committed:

Changes not staged for commit:

part; the latter preceded by 50*"-" to make it stick out more.

ec8a896eb5 t7508: .gitignore 'expect' and 'output' files
These files are used to observe the behaviour of the 'status'
command and if there weren't any such observer, the expected
output from 'status' wouldn't even mention them.

Place them in .gitignore to unclutter the output expected by the
tests.  An added benefit is that future tests can add such files
that are purely for use by the observer, i.e. the tests themselves,
by naming them as expect-foo and/or output-bar.

4aff646d17 archive-zip: mark text files in archives
Set the text flag for ZIP archive entries that look like text files so
that unzip -a can be used to perform end-of-line conversions.  Info-ZIP
zip does the same.

Detect binary files the same way as git diff and git grep do, namely by
checking for the attribute "diff" and its negation "-diff", and if none
is found by falling back to checking for the presence of NUL bytes in
the first few bytes of the file contents.

7-Zip, Windows' built-in ZIP functionality and Info-ZIP unzip without
the switch -a are not affected by the change and still extract text
files without doing any end-of-line conversions.

NB: The actual end-of-line style used in the archive entries doesn't
matter to unzip -a, as it converts any CR, CRLF and LF to the line end
characters appropriate for the platform it is running on.

5ee875852e log --decorate: do not leak "commit" color into the next item
In "git log --decorate", you would see the commit header like this:

    commit ... (HEAD, jc/decorate-leaky-separator-color)

where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.

If you wanted to paint the HEAD and local branch name in the same
color as the body text (perhaps because cyan and green are too faint
on a black-on-white terminal to be readable), you would not want to
have to say

    [color "decorate"]
        head = black
        branch = black

because that you would not be able to reuse same configuration on a
white-on-black terminal.  You would naively expect

    [color "decorate"]
        head = normal
	branch = normal

to work, but unfortunately it does not.  It paints the string "HEAD"
and the branch name in the same color as the opening parenthesis or
comma between the decoration elements.  This is because the code
forgets to reset the color after printing the "prefix" in its own
color.

It theoretically is possible that some people were expecting and
relying on that the attribute set as the "diff.commit" color, which
is used to draw these opening parenthesis and inter-item comma, is
inherited by the drawing of branch names, but it is not how the
coloring works everywhere else.

ab27389aff diff --shortstat --dirstat: remove duplicate output

The same duplication happens for --shortstat together with --dirstat=files, but
not for --shortstat together with --dirstat=lines.

4d6be03b95 diffcore-rename: avoid processing duplicate destinations
The rename code cannot handle an input where we have
duplicate destinations (i.e., more than one diff_filepair in
the queue with the same string in its pair->two->path). We
end up allocating only one slot in the rename_dst mapping.
If we fill in the diff_filepair for that slot, when we
re-queue the results, we may queue that filepair multiple
times. When the diff is finally flushed, the filepair is
processed and free()d multiple times, leading to heap
corruption.

This situation should only happen when a tree diff sees
duplicates in one of the trees (see the added test for a
detailed example). Rather than handle it, the sanest thing
is just to turn off rename detection altogether for the
diff.

817d03e105 test_ln_s_add: refresh stat info of fake symbolic links
We have a helper function test_ln_s_add that inserts a symbolic link
into the index even if the file system does not support symbolic links.
There is a small flaw in the emulation path: the added entry does not
pick up stat information of the fake symbolic link from the file system,
as a consequence, the index is not exactly the same as for the "regular"
path (where symbolic links are available). To fix this, just call
git update-index again.

This flaw was revealed by the earlier change that tightened
compare_diff_raw(), because a test case in t4008 depends on the
correctly updated index.

86ceb337ec connect.c: allow ssh://user@[2001:db8::1]/repo.git
The ssh:// syntax was added in 2386d658 (Add first cut at "git
protocol" connect logic., 2005-07-13), it accepted
ssh://user@2001:db8::1/repo.git, which is now legacy.

Over the years the parser was improved to support [] and port numbers,
but the combination of ssh://user@[2001:db8::1]:222/repo.git did
never work.

The only only way to use a user name, a literall IPV6 address and a port
number was ssh://[user@2001:db8::1]:222/repo.git

(Thanks to Christian Taube <lists@hcf.yourweb.de> for reporting this long
standing issue)

New users would use ssh://user@[2001:db8::1]:222/repo.git,
so change the parser to handle it correctly.

Support the old legacy URLs as well, to be backwards compatible,
and avoid regressions for users which upgrade an existing installation
to a later Git version.

b485373052 daemon: sanitize incoming virtual hostname
We use the daemon_avoid_alias function to make sure that the
pathname the user gives us is sane. However, after applying
that check, we might then interpolate the path using a
string given by the server admin, but which may contain more
untrusted data from the client. We should be sure to
sanitize this data, as well.

We cannot use daemon_avoid_alias here, as it is more strict
than we need in requiring a leading '/'. At the same time,
we can be much more strict here. We are interpreting a
hostname, which should not contain slashes or excessive runs
of dots, as those things are not allowed in DNS names.

Note that in addition to cleansing the hostname field, we
must check the "canonical hostname" (%CH) as well as the
port (%P), which we take as a raw string.  For the canonical
hostname, this comes from an actual DNS lookup on the
accessed IP, which makes it a much less likely vector for
problems. But it does not hurt to sanitize it in the same
way. Unfortunately we cannot test this case easily, as it
would involve a custom hostname lookup.

We do not need to check %IP, as it comes straight from
inet_ntop, so must have a sane form.

a933c23e66 commit: avoid race when creating orphan commits
If HEAD doesn't point at anything during the initial check, then we
should make sure that it *still* doesn't point at anything when we are
ready to update the reference. Otherwise, another process might commit
while we are working (e.g., while we are waiting for the user to edit
the commit message) and we will silently overwrite it.

a908a31c34 commit: add tests of commit races
Committing involves the following steps:

1. Determine the current value of HEAD (if any).
2. Create the new commit object.
3. Update HEAD.

Please note that step 2 can take arbitrarily long, because it might
involve the user editing a commit message.

If a second process sneaks in a commit during step 2, then the first
commit process should fail. This is usually done correctly, because
step 3 verifies that HEAD still points at the same commit that it
pointed to during step 1.

However, if there is a race when creating an *orphan* commit, then the
test in step 3 is skipped.

Add tests for proper handling of such races. One of the new tests
fails. It will be fixed in a moment.

bd9150b7e5 t/diff-lib: check exact object names in compare_diff_raw

stripping away the object names as well.

While we do not want to require the exact object names the tests
expect to be maintained, as it would be seen as an extra burden,
this would have prevented us catching a silly bug such as showing
non 0{40} object name on the preimage side of an addition or on the
postimage side of a deletion, because all [0-9a-f]{40} strings were
considered equally OK.

e0d201b616 apply: do not touch a file beyond a symbolic link
Because Git tracks symbolic links as symbolic links, a path that
has a symbolic link in its leading part (e.g. path/to/dir/file,
where path/to/dir is a symbolic link to somewhere else, be it
inside or outside the working tree) can never appear in a patch
that validly applies, unless the same patch first removes the
symbolic link to allow a directory to be created there.

Detect and reject such a patch.

Things to note:

 - Unfortunately, we cannot reuse the has_symlink_leading_path()
   from dir.c, as that is only about the working tree, but "git
   apply" can be told to apply the patch only to the index or to
   both the index and to the working tree.

 - We cannot directly use has_symlink_leading_path() even when we
   are applying only to the working tree, as an early patch of a
   valid input may remove a symbolic link path/to/dir and then a
   later patch of the input may create a path path/to/dir/file, but
   "git apply" first checks the input without touching either the
   index or the working tree.  The leading symbolic link check must
   be done on the interim result we compute in-core (i.e. after the
   first patch, there is no path/to/dir symbolic link and it is
   perfectly valid to create path/to/dir/file).

   Similarly, when an input creates a symbolic link path/to/dir and
   then creates a file path/to/dir/file, we need to flag it as an
   error without actually creating path/to/dir symbolic link in the
   filesystem.

Instead, for any patch in the input that leaves a path (i.e. a non
deletion) in the result, we check all leading paths against the
resulting tree that the patch would create by inspecting all the
patches in the input and then the target of patch application
(either the index or the working tree).

This way, we catch a mischief or a mistake to add a symbolic link
path/to/dir and a file path/to/dir/file at the same time, while
allowing a valid patch that removes a symbolic link path/to/dir and
then adds a file path/to/dir/file.

c536c0755f apply: reject input that touches outside the working area
By default, a patch that affects outside the working area (either a
Git controlled working tree, or the current working directory when
"git apply" is used as a replacement of GNU patch) is rejected as a
mistake (or a mischief).  Git itself does not create such a patch,
unless the user bends over backwards and specifies a non-standard
prefix to "git diff" and friends.

When `git apply` is used as a "better GNU patch", the user can pass
the `--unsafe-paths` option to override this safety check. This
option has no effect when `--index` or `--cached` is in use.

The new test was stolen from Jeff King with slight enhancements.
Note that a few new tests for touching outside the working area by
following a symbolic link are still expected to fail at this step,
but will be fixed in later steps.

b0a4264277 sha1_file: fix iterating loose alternate objects
The string in 'base' contains a path suffix to a specific object;
when its value is used, the suffix must either be filled (as in
stat_sha1_file, open_sha1_file, check_and_freshen_nonlocal) or
cleared (as in prepare_packed_git) to avoid junk at the end.

660c889e (sha1_file: add for_each iterators for loose and packed
objects, 2014-10-15) introduced loose_from_alt_odb(), but this did
neither and treated 'base' as a complete path to the "base" object
directory, instead of a pointer to the "base" of the full path
string.

The trailing path after 'base' is still initialized to NUL, hiding
the bug in some common cases.  Additionally the descendent
for_each_file_in_obj_subdir() function swallows ENOENT, so an error
only shows if the alternate's path was last filled with a valid
object (where statting /path/to/existing/00/0bjectfile/00 fails).

5e0be134d3 config: do not ungetc EOF
When we are parsing a config value, if we see a carriage
return, we fgetc the next character to see if it is a
line feed (in which case we silently drop the CR). If it
isn't, we then ungetc the character, and take the literal
CR.

But we never check whether we in fact got a character at
all. If the config file ends in CR, we will get EOF here,
and try to ungetc EOF. This works OK for a real stdio
stream. The ungetc returns an error, and the next fgetc will
then return EOF again.

However, our custom buffer-based stream is not so fortunate.
It happily rewinds the position of the stream by one
character, ignoring the fact that we fed it EOF. The next
fgetc call returns the final CR again, over and over, and we
end up in an infinite loop.

This gives git servers a chance to display remote error messages in

8b9c2dd4de dumb-http: do not pass NULL path to parse_pack_index
Once upon a time, dumb http always fetched .idx files
directly into their final location, and then checked their
validity with parse_pack_index. This was refactored in
commit 750ef42 (http-fetch: Use temporary files for
pack-*.idx until verified, 2010-04-19), which uses the
following logic:

  1. If we have the idx already in place, see if it's
     valid (using parse_pack_index). If so, use it.

  2. Otherwise, fetch the .idx to a tempfile, check
     that, and if so move it into place.

  3. Either way, fetch the pack itself if necessary.

However, it got step 1 wrong. We pass a NULL path parameter
to parse_pack_index, so an existing .idx file always looks
broken. Worse, we do not treat this broken .idx as an
opportunity to re-fetch, but instead return an error,
ignoring the pack entirely. This can lead to a dumb-http
fetch failing to retrieve the necessary objects.

This doesn't come up much in practice, because it must be a
packfile that we found out about (and whose .idx we stored)
during an earlier dumb-http fetch, but whose packfile we
_didn't_ fetch. I.e., we did a partial clone of a
repository, didn't need some packfiles, and now a followup
fetch needs them.

2988289f2c apply: make update_pre_post_images() sanity check the given postlen
"git apply --whitespace=fix" used to be able to assume that fixing
errors will always reduce the size by e.g. stripping whitespaces at
the end of lines or collapsing runs of spaces into tabs at the
beginning of lines.  An update to accomodate fixes that lengthens
the result by e.g. expanding leading tabs into spaces were made long
time ago but the logic miscounted the necessary space after such
whitespace fixes, leading to either under-allocation or over-usage
of already allocated space.

Illustrate this with a runtime sanity-check to protect us from
future breakage.  The test was stolen from Kyle McKay who helped
to identify the problem.

edb72d5511 rebase -i: use full object name internally throughout the script
In earlier days, the abbreviated commit object name shown to the end
users were generated with hardcoded --abbrev=7; 56895038 (rebase
-i: respect core.abbrev, 2013-09-28) tried to make it honor the user
specified core.abbrev, but it missed the very initial invocation of
the editor.

These days, we try to use the full 40-hex object names internally to
avoid ambiguity that can arise after rebase starts running.  Newly
created objects during the rebase may share the same prefix with
existing commits listed in the insn sheet.  These object names are
shortened just before invoking the sequence editor to present the
insn sheet to the end user, and then expanded back to full object
names when the editor returns.

But the code still used the shortened names when preparing the insn
sheet for the very first time, resulting "7 hexdigits or more"
output to the user.  Change the code to use full 40-hex commit
object names from the very beginning to make things more uniform.

33cae5428a transport-helper: do not request symbolic refs to remote helpers
A typical remote helper will return a `list` of refs containing a symbolic
ref HEAD, pointing to, e.g. refs/heads/master. In the case of a clone, all
the refs are being requested through `fetch` or `import`, including the
symbolic ref.

While this works properly, in some cases of a fetch, like `git fetch url`
or `git fetch origin HEAD`, or any fetch command involving a symbolic ref
without also fetching the corresponding ref it points to, the fetch command
fails with:

  fatal: bad object 0000000000000000000000000000000000000000
  error: <remote> did not send all necessary objects

(in the case the remote helper returned '?' values to the `list` command).

This is because there is only one ref given to fetch(), and it's not
further resolved to something at the end of fetch_with_import().

While this can be somehow handled in the remote helper itself, by adding
a refspec for the symbolic ref, and storing an explicit ref in a private
namespace, and then handling the `import` for that symbolic ref
specifically, very few existing remote helpers are actually doing that.

So, instead of requesting the exact list of wanted refs to remote helpers,
treat symbolic refs differently and request the ref they point to instead.
Then, resolve the symbolic refs values based on the pointed ref.
This assumes there is no more than one level of indirection (a symbolic
ref doesn't point to another symbolic ref).

eae69530ae tests: correct misuses of POSIXPERM
POSIXPERM requires that a later call to stat(2) (hence "ls -l")
faithfully reproduces what an earlier chmod(2) did.  Some
filesystems cannot satisify this.

SANITY requires that a file or a directory is indeed accessible (or
inaccessible) when its permission bits would say it ought to be
accessible (or inaccessible).  Running tests as root would lose this
prerequisite for obvious reasons.

Fix a few tests that misuse POSIXPERM.

t0061-run-command.sh has two uses of POSIXPERM.

 - One checks that an attempt to execute a file that is marked as
   unexecutable results in a failure with EACCES; I do not think
   having root-ness or any other capability that busts the
   filesystem permission mode bits will make you run an unexecutable
   file, so this should be left as-is.  The test does not have
   anything to do with SANITY.

 - The other one expects 'git nitfol' runs the alias when an
   alias.nitfol is defined and a directory on the PATH is marked as
   unreadable and unsearchable.  I _think_ the test tries to reject
   the alternative expectation that we want to refuse to run the
   alias because it would break "no alias may mask a command" rule
   if a file 'git-nitfol' exists in the unreadable directory but we
   cannot even determine if that is the case.  Under !SANITY that
   busts the permission bits, this test no longer checks that, so it
   must be protected with SANITY.

t1509-root-worktree.sh expects to be run on a / that is writable by
the user and sees if Git behaves "sensibly" when /.git is the
repository to govern a worktree that is the whole filesystem, and
also if Git behaves "sensibly" when / itself is a bare repository
with refs, objects, and friends (I find the definition of "behaves
sensibly" under these conditions hard to fathom, but it is a
different matter).

The implementation of the test is very much problematic.

 - It requires POSIXPERM, but it does not do chmod or checks modes
   in any way.

 - It runs "rm /*" and "rm -fr /refs /objects ..." in one of the
   tests, and also does "cd / && git init --bare".  If done on a
   live system that takes advantages of the "feature" being tested,
   these obviously will clobber the system.  But there is no guard
   against such a breakage.

 - It uses "test $UID = 0" to see rootness, which now should be
   spelled "! test_have_prereq NOT_ROOT"

1767c51787 t/lib-httpd: switch SANITY check for NOT_ROOT
The SANITY prerequisite is really about whether the
filesystem will respect the permissions we set, and being
root is only one part of that. But the httpd tests really
just care about not being root, as they are trying to avoid
weirdness in apache (see a1a3011 for details).

Let's switch out SANITY for a new NOT_ROOT prerequisite,
which will let us tweak SANITY more freely.

We implement NOT_ROOT by checking `id -u`, which is in POSIX
and seems to be available even on MSYS.  Note that we cannot
just call this "ROOT" and ask for "!ROOT". The possible
outcomes are:

  1. we know we are root

  2. we know we are not root

  3. we could not tell, because `id` was not available

We should conservatively treat (3) as "does not have the
prerequisite", which means that a naive negation would not
work.

d0a042a186 t1050-large: generate large files without dd
For some unknown reason, the dd on my Windows box segfaults randomly,
but since recently, it does so much more often than it used to, which
makes running the test suite burdensome.

Use printf to write large files instead of dd. To emphasize that three
of the large blobs are exact copies, use cp to allocate them.

The new code makes the files a bit smaller, and they are not sparse
anymore, but the tests do not depend on these properties. We do not want
to use test-genrandom here (which is used to generate large files
elsewhere in t1050), so that the files can be compressed well (which
keeps the run-time short).

The files are now large text files, not binary files. But since they
are larger than core.bigfilethreshold they are diagnosed as binary
by Git. For this reason, the 'git diff' tests that check the output
for "Binary files differ" still pass.

22dfa8a23d log: teach --invert-grep option
"git log --grep=<string>" shows only commits with messages that
match the given string, but sometimes it is useful to be able to
show only commits that do *not* have certain messages (e.g. "show
me ones that are not FIXUP commits").

Originally, we had the invert-grep flag in grep_opt, but because
"git grep --invert-grep" does not make sense except in conjunction
with "--files-with-matches", which is already covered by
"--files-without-matches", it was moved it to revisions structure.
To have the flag there expresses the function to the feature better.

When the newly inserted two tests run, the history would have commits
with messages "initial", "second", "third", "fourth", "fifth", "sixth"
and "Second", committed in this order.  The commits that does not match
either "th" or "Sec" is "second" and "initial". For the case insensitive
case only "initial" matches.

b6160d950c for-each-ref: always check stat_tracking_info()'s return value
The code handling %(upstream:track) and %(upstream:trackshort)
assumed that it always had a valid branch that had been sanitized
earlier in populate_value(), and thus did not check the return value
of the call to stat_tracking_info().

While there is indeed some sanitization code that basically
corresponds to stat_tracking_info() returning 0 (no base branch
set), the function can also return -1 when the base branch did exist
but has since then been deleted.

In this case, num_ours and num_theirs had undefined values and a
call to `git for-each-ref --format="%(upstream:track)"` could print
spurious values such as

  [behind -111794512]
  [ahead 38881640, behind 5103867]

even for repositories with one single commit.

Verify stat_tracking_info()'s return value and do not print anything
if it returns -1. This behavior also matches the documentation ("has
no effect if the ref does not have tracking information associated
with it").

0855331941 receive-pack: support push-to-checkout hook
When receive.denyCurrentBranch is set to updateInstead, a push that
tries to update the branch that is currently checked out is accepted
only when the index and the working tree exactly matches the
currently checked out commit, in which case the index and the
working tree are updated to match the pushed commit.  Otherwise the
push is refused.

This hook can be used to customize this "push-to-deploy" logic.  The
hook receives the commit with which the tip of the current branch is
going to be updated, and can decide what kind of local changes are
acceptable and how to update the index and the working tree to match
the updated tip of the current branch.

For example, the hook can simply run `git read-tree -u -m HEAD "$1"`
in order to emulate 'git fetch' that is run in the reverse direction
with `git push`, as the two-tree form of `read-tree -u -m` is
essentially the same as `git checkout` that switches branches while
keeping the local changes in the working tree that do not interfere
with the difference between the branches.

102fc80d32 test-lib.sh: do tests for color support after changing HOME
If ncurses needs ~/.terminfo for the current $TERM, then tput will
succeed before changing HOME to $TRASH_DIRECTORY but fail afterward.
Move the tests that determine whether there is color support after
changing HOME so that color=t is set if and only if tput would succeed
when say_color() is run.

Note that color=t is now set after --no-color is processed, so the
condition to set color=t has changed:  it is now set only if
color has not already been set to the empty string by --no-color.

This disables color support for those that need ~/.terminfo for
their TERM, but it's better than filling the screen with:

    tput: unknown terminal "custom-terminal-name-here"

An alternative would be to symlink or copy the user's terminfo
database into $TRASH_DIRECTORY, but this is tricky due to the lack of
a standard name for the terminfo database (for example, instead of a
~/.terminfo directory, NetBSD uses a ~/.terminfo.cdb database file).

0120b8c85c git-prompt.sh: allow to hide prompt for ignored pwd
Optionally set __git_ps1 to display nothing when present working
directory is ignored, triggered by the new environment variable
GIT_PS1_HIDE_IF_PWD_IGNORED. This environment variable may be
overridden on any repository by setting bash.hideIfPwdIgnored to
"false". In the absence of GIT_PS1_HIDE_IF_PWD_IGNORED this change
has no effect.

Many people manage e.g. dotfiles in their home directory with git.
This causes the prompt generated by __git_ps1 to refer to that "top
level" repo while working in any descendant directory. That can be
distracting, so this patch helps one shut off that noise.

d91175b212 update-server-info: create info/* with mode 0666
Prior to d38379e (make update-server-info more robust, 2014-09-13),
we used a straight "fopen" to create the info/refs and
objects/info/packs files, which creates the file using mode 0666
(less the default umask).

In d38379e, we switched to creating the file with mkstemp to get a
unique filename. But mkstemp also uses the more restrictive 0600
mode to create the file. This was an unintended side effect that we
did not want, and causes problems when the repository is served by a
different user than the one running update-server-info (it is not
readable by a dumb http server running as `www`, for example).

We can fix this by using git_mkstemp_mode and specifying 0666 to
make sure that the umask is honored.

Note that we could also say "just use core.sharedrepository", as we
do call adjust_shared_perm on the result before renaming it into
place.  But that should not be necessary as long as everybody
involved is using permissive umask to allow HTTP server to read
necessary files.

d05c77cca2 t1301: set umask in reflog sharedrepository=group test
The t1301 script sets the umask globally before many of the
tests. Most of the tests that care about the umask then set
it explicitly at the start of the test. However, one test
does not, and relies on the 077 umask setting from earlier
tests. This is fragile and can break if another test is
added in between. Let's be more explicit.

6aaf956b08 is_hfs_dotgit: loosen over-eager match of \u{..47}
Our is_hfs_dotgit function relies on the hackily-implemented
next_hfs_char to give us the next character that an HFS+
filename comparison would look at. It's hacky because it
doesn't implement the full case-folding table of HFS+; it
gives us just enough to see if the path matches ".git".

At the end of next_hfs_char, we use tolower() to convert our
32-bit code point to lowercase. Our tolower() implementation
only takes an 8-bit char, though; it throws away the upper
24 bits. This means we can't have any false negatives for
is_hfs_dotgit. We only care about matching 7-bit ASCII
characters in ".git", and we will correctly process 'G' or
'g'.

However, we _can_ have false positives. Because we throw
away the upper bits, code point \u{0147} (for example) will
look like 'G' and get downcased to 'g'. It's not known
whether a sequence of code points whose truncation ends up
as ".git" is meaningful in any language, but it does not
hurt to be more accurate here. We can just pass out the full
32-bit code point, and compare it manually to the upper and
lowercase characters we care about.

74c4de5832 checkout-index: fix --temp relative path mangling
checkout-index --temp only properly prints relative paths which are
descendants of the current directory. Paths in ancestor or sibling
directories (or their children) are often printed in mangled form. For
example:

    mkdir a bbb &&
    >file &&
    >bbb/file &&
    git update-index --add file bbb/file &&
    cd a &&
    git checkout-index --temp ../file ../bbb/file

prints:

    .merge_file_ooblek  le
    .merge_file_igloo0  b/file

rather than the correct:

    .merge_file_ooblek  ../file
    .merge_file_igloo0  ../bbb/file

Internally, given the above example, checkout-index prefixes each input
argument with the name of the current directory ("a/", in this case),
and then assumes that it can simply skip forward by strlen("a/") bytes
to recover the original name. This works for files in the current
directory or its descendants, but fails for files in ancestors or
siblings (or their children) due to path normalization.

For instance, given "../file", "a/" is prepended, giving "a/../file".
Path normalization folds out "a/../", resulting in "file". Attempting
to recover the original name by skipping strlen("a/") bytes gives the
incorrect "le" rather than the desired "../file".

Fix this by taking advantage of write_name_quoted_relative() to recover
the original name properly, rather than assuming that it can be
recovered by skipping strlen(prefix) bytes.

As a bonus, this also fixes a bug in which checkout-index --temp
accessed and printed memory beyond the end-of-string. For instance,
within a subdirectory named "subdirectory", and given argument
"../file", prefixing would give "subdirectory/../file", which would
become "file" after normalization. checkout-index would then attempt to
recover the original name by skipping strlen("subdirectory/") bytes of
"file", which placed it well beyond end-of-string. Despite this error,
it often appeared to give the correct result, but only due to an
accident of implementation which left an apparently correct copy of the
path in memory following the normalized value. In particular, handed
"subdirectory/../file", in-place processing by normalize_path_copy_len()
resulted in "file\0rectory/../file". When checkout-index skipped
strlen("subdirectory/") bytes, it ended up back at "../file" and thus
appeared to give the correct answer, despite being past end-of-string.

052b2551ad t2004: demonstrate broken relative path printing
checkout-index --temp only properly prints relative paths which are
descendants of the current directory. Paths in ancestor or sibling
directories (or their children) are often printed in mangled form. For
example:

    mkdir a bbb &&
    >file &&
    >bbb/file &&
    git update-index --add file bbb/file &&
    cd a &&
    git checkout-index --temp ../file ../bbb/file

prints:

    .merge_file_ooblek  le
    .merge_file_igloo0  b/file

rather than the correct:

    .merge_file_ooblek  ../file
    .merge_file_igloo0  ../bbb/file

Unfortunately, testing is complicated slightly by relative paths
sometimes _appearing_ to be printed correctly, but this is an accident
of implementation in which a "correct" copy of the string exists in
memory beyond the end of the real string, and that "correct" copy gets
printed. This test takes care to avoid the accidentally "correct"
behavior by testing with a filename longer than the directory name in
which checkout-index is invoked.

d69360c6b1 t0090: tweak awk statement for Solaris /usr/xpg4/bin/awk
The awk statements previously used in this test weren't compatible
with the native versions of awk on Solaris:

    echo "dir" | /bin/awk -v c=0 '$1 {++c} END {print c}'
    awk: syntax error near line 1
    awk: bailing out near line 1

    echo "dir" | /usr/xpg4/bin/awk -v c=0 '$1 {++c} END {print c}'
    0

Even though we do not cater to tools in /usr/bin on Solaris that
have and are overridden by corresponding ones in /usr/xpg?/bin,
in this case, even the XPG version does not work correctly.

With GNU awk for comparison:

    echo "dir" | /opt/csw/gnu/awk -v c=0 '$1 {++c} END {print c}'
    1

which is what this test expects (and is in line with POSIX; non-empty
string is true and an empty string is false).

Work this issue around by using $1 != "" to state more explicitly
that we are skipping empty lines.

d08c13b947 fsck: complain about NTFS ".git" aliases in trees
Now that the index can block pathnames that can be mistaken
to mean ".git" on NTFS and FAT32, it would be helpful for
fsck to notice such problematic paths. This lets servers
which use receive.fsckObjects block them before the damage
spreads.

Note that the fsck check is always on, even for systems
without core.protectNTFS set. This is technically more
restrictive than we need to be, as a set of users on ext4
could happily use these odd filenames without caring about
NTFS.

However, on balance, it's helpful for all servers to block
these (because the paths can be used for mischief, and
servers which bother to fsck would want to stop the spread
whether they are on NTFS themselves or not), and hardly
anybody will be affected (because the blocked names are
variants of .git or git~1, meaning mischief is almost
certainly what the tree author had in mind).

Ideally these would be controlled by a separate
"fsck.protectNTFS" flag. However, it would be much nicer to
be able to enable/disable _any_ fsck flag individually, and
any scheme we choose should match such a system. Given the
likelihood of anybody using such a path in practice, it is
not unreasonable to wait until such a system materializes.

2b4c6efc82 read-cache: optionally disallow NTFS .git variants
The point of disallowing ".git" in the index is that we
would never want to accidentally overwrite files in the
repository directory. But this means we need to respect the
filesystem's idea of when two paths are equal. The prior
commit added a helper to make such a comparison for NTFS
and FAT32; let's use it in verify_path().

We make this check optional for two reasons:

  1. It restricts the set of allowable filenames, which is
     unnecessary for people who are not on NTFS nor FAT32.
     In practice this probably doesn't matter, though, as
     the restricted names are rather obscure and almost
     certainly would never come up in practice.

  2. It has a minor performance penalty for every path we
     insert into the index.

This patch ties the check to the core.protectNTFS config
option. Though this is expected to be most useful on Windows,
we allow it to be set everywhere, as NTFS may be mounted on
other platforms. The variable does default to on for Windows,
though.

We do not allow ".git" to enter into the index as a path
component, because checking out the result to the working
tree may causes confusion for subsequent git commands.
However, on case-insensitive file systems, ".Git" or ".GIT"
is the same. We should catch and prevent those, too.

Note that technically we could allow this for repos on
case-sensitive filesystems. But there's not much point. It's

b0f4c9087e t: support clang/gcc AddressSanitizer
When git is compiled with "-fsanitize=address" (using clang
or gcc >= 4.8), all invocations of git will check for buffer
overflows. This is similar to running with valgrind, except
that it is more thorough (because of the compiler support,
function-local buffers can be checked, too) and runs much
faster (making it much less painful to run the whole test
suite with the checks turned on).

Unlike valgrind, the magic happens at compile-time, so we
don't need the same infrastructure in the test suite that we
did to support --valgrind. But there are two things we can
help with:

  1. On some platforms, the leak-detector is on by default,
     and causes every invocation of "git init" (and thus
     every test script) to fail. Since running git with
     the leak detector is pointless, let's shut it off
     automatically in the tests, unless the user has already
     configured it.

  2. When apache runs a CGI, it clears the environment of
     unknown variables. This means that the $ASAN_OPTIONS
     config doesn't make it to git-http-backend, and it
     dies due to the leak detector. Let's mark the variable
     as OK for apache to pass.

With these two changes, running

    make CC=clang CFLAGS=-fsanitize=address test

works out of the box.

0e729c7ed5 update-ref: fix "verify" command with missing <oldvalue>
If "git update-ref --stdin" was given a "verify" command with no
"<newvalue>" at all (not even zeros), the code was mistakenly setting
have_old=0 (and leaving old_sha1 uninitialized). But this is
incorrect: this command is supposed to verify that the reference
doesn't exist. So in this case we really need old_sha1 to be set to
null_sha1 and have_old to be set to 1.

Moreover, since have_old was being set to zero, *no* check of the old
value was being done, so the new value of the reference was being set
unconditionally to the value in new_sha1. new_sha1, in turn, was set
to null_sha1 in the expectation that that was the old value and it
shouldn't be changed. But because the precondition was not being
checked, the result was that the reference was being deleted
unconditionally.

So, if <oldvalue> is missing, set have_old unconditionally and set
old_sha1 to null_sha1.

8e9faf27c1 pkt-line: allow writing of LARGE_PACKET_MAX buffers
When we send out pkt-lines with refnames, we use a static
1000-byte buffer. This means that the maximum size of a ref
over the git protocol is around 950 bytes (the exact size
depends on the protocol line being written, but figure on a sha1
plus some boilerplate).

This is enough for any sane workflow, but occasionally odd
things happen (e.g., a bug may create a ref "foo/foo/foo/..."
accidentally).  With the current code, you cannot even use
"push" to delete such a ref from a remote.

Let's switch to using a strbuf, with a hard-limit of
LARGE_PACKET_MAX (which is specified by the protocol).  This
matches the size of the readers, as of 74543a0 (pkt-line:
provide a LARGE_PACKET_MAX static buffer, 2013-02-20).
Versions of git older than that will complain about our
large packets, but it's really no worse than the current
behavior. Right now the sender barfs with "impossibly long
line" trying to send the packet, and afterwards the reader
will barf with "protocol error: bad line length %d", which
is arguably better anyway.

Note that we're not really _solving_ the problem here, but
just bumping the limits. In theory, the length of a ref is
unbounded, and pkt-line can only represent sizes up to
65531 bytes. So we are just bumping the limit, not removing
it.  But hopefully 64K should be enough for anyone.

As a bonus, by using a strbuf for the formatting we can
eliminate an unnecessary copy in format_buf_write.

This change allows git-svn to support setting subversion properties.

It is useful for manually setting properties when committing to a
subversion repo that *requires* properties to be set without requiring
moving your changeset to separate subversion checkout in order to
set props.

This change is initially from David Fraser, appearing at:

  http://mid.gmane.org/1927112650.1281253084529659.JavaMail.root@klofta.sjsoft.com>

They are now forward-ported to most recent git along with fixes to
deal with files in subdirectories.

Style and functional changes from Eric Wong have been taken
in their entirety from:

  http://mid.gmane.org/20141201094911.GA13931@dcvr.yhbt.net

There is a nit to point out: the code does not support
adding props unless there are also content changes to the files as
well.  This is demonstrated in the testcase.

    - improve shell portability for tests

7add441984 fsck: properly bound "invalid tag name" error message
When we detect an invalid tag-name header in a tag object,
like, "tag foo bar\n", we feed the pointer starting at "foo
bar" to a printf "%s" formatter. This shows the name, as we
want, but then it keeps printing the rest of the tag buffer,
rather than stopping at the end of the line.

Our tests did not notice because they look only for the
matching line, but the bug is that we print much more than
we wanted to. So we also adjust the test to be more exact.

Note that when fscking tags with "index-pack --strict", this
is even worse. index-pack does not add a trailing
NUL-terminator after the object, so we may actually read
past the buffer and print uninitialized memory. Running
t5302 with valgrind does notice the bug for that reason.

e5e73ff20b for_each_reflog_ent_reverse: fix newlines on block boundaries
When we read a reflog file in reverse, we read whole chunks
of BUFSIZ bytes, then loop over the buffer, parsing any
lines we find. We find the beginning of each line by looking
for the newline from the previous line. If we don't find
one, we know that we are either at the beginning of
the file, or that we have to read another block.

In the latter case, we stuff away what we have into a
strbuf, read another block, and continue our parse. But we
missed one case here. If we did find a newline, and it is at
the beginning of the block, we must also stuff that newline
into the strbuf, as it belongs to the block we are about to
read.

The minimal fix here would be to add this special case to
the conditional that checks whether we found a newline.
But we can make the flow a little clearer by rearranging a
bit: we first handle lines that we are going to show, and
then at the end of each loop, stuff away any leftovers if
necessary. That lets us fold this special-case in with the
more common "we ended in the middle of a line" case.

59b386526a credential: let helpers tell us to quit
When we are trying to fill a credential, we loop over the
set of defined credential-helpers, then fall back to running
askpass, and then finally prompt on the terminal. Helpers
which cannot find a credential are free to tell us nothing,
but they cannot currently ask us to stop prompting.

This patch lets them provide a "quit" attribute, which asks
us to stop the process entirely (avoiding running more
helpers, as well as the askpass/terminal prompt).

This has a few possible uses:

  1. A helper which prompts the user itself (e.g., in a
     dialog) can provide a "cancel" button to the user to
     stop further prompts.

  2. Some helpers may know that prompting cannot possibly
     work. For example, if their role is to broker a ticket
     from an external auth system and that auth system
     cannot be contacted, there is no point in continuing
     (we need a ticket to authenticate, and the user cannot
     provide one by typing it in).

df56607dff git-common-dir: make "modules/" per-working-directory directory
Each working directory of main repository has its own working directory
of submodule, and in most cases they should be checked out to different
revisions. So they should be separated.

It looks logical to make submodule instances in different working
directories to reuse the submodule directory in the common dir of
the main repository, and probably this is how "checkout --to" should
initialize them called on the main repository, but they also should work
fine being completely separated clones.

Testfile t7410-submodule-checkout-to.sh demostrates the behavior.

3473ad0cf6 checkout: don't require a work tree when checking out into a new one
For normal use cases, it does not make sense for 'checkout' to work on
a bare repository, without a worktree. But "checkout --to" is an
exception because it _creates_ a new worktree. Allow this option to
run on bare repositories.

People who check out from a bare repository should remember that
core.logallrefupdates is off by default and it should be turned back
on. `--to` cannot do this automatically behind the user's back because
some user may deliberately want no reflog.

For people interested in repository setup/discovery code,
is_bare_repository_cfg (aka "core.bare") is unchanged by this patch,
which means 'true' by default for bare repos. Fortunately when we get
the repo through a linked checkout, is_bare_repository_cfg is never
used. So all is still good.

6cfbdcb2ab git_path(): keep "info/sparse-checkout" per work-tree
Currently git_path("info/sparse-checkout") resolves to
$GIT_COMMON_DIR/info/sparse-checkout in multiple worktree mode. It
makes more sense for the sparse checkout patterns to be per worktree,
so you can have multiple checkouts with different parts of the tree.

With this, "git checkout --to <new>" on a sparse checkout will create
<new> as a full checkout. Which is expected, it's how a new checkout
is made. The user can reshape the worktree afterwards.

23af91d102 prune: strategies for linked checkouts
(alias R=$GIT_COMMON_DIR/worktrees/<id>)

 - linked checkouts are supposed to keep its location in $R/gitdir up
   to date. The use case is auto fixup after a manual checkout move.

 - linked checkouts are supposed to update mtime of $R/gitdir. If
   $R/gitdir's mtime is older than a limit, and it points to nowhere,
   worktrees/<id> is to be pruned.

 - If $R/locked exists, worktrees/<id> is not supposed to be pruned. If
   $R/locked exists and $R/gitdir's mtime is older than a really long
   limit, warn about old unused repo.

 - "git checkout --to" is supposed to make a hard link named $R/link
   pointing to the .git file on supported file systems to help detect
   the user manually deleting the checkout. If $R/link exists and its
   link count is greated than 1, the repo is kept.

c7b3a3d2fe $GIT_COMMON_DIR: a new environment variable
This variable is intended to support multiple working directories
attached to a repository. Such a repository may have a main working
directory, created by either "git init" or "git clone" and one or more
linked working directories. These working directories and the main
repository share the same repository directory.

In linked working directories, $GIT_COMMON_DIR must be defined to point
to the real repository directory and $GIT_DIR points to an unused
subdirectory inside $GIT_COMMON_DIR. File locations inside the
repository are reorganized from the linked worktree view point:

 - worktree-specific such as HEAD, logs/HEAD, index, other top-level
   refs and unrecognized files are from $GIT_DIR.

 - the rest like objects, refs, info, hooks, packed-refs, shallow...
   are from $GIT_COMMON_DIR (except info/sparse-checkout, but that's
   a separate patch)

Scripts are supposed to retrieve paths in $GIT_DIR with "git rev-parse
--git-path", which will take care of "$GIT_DIR vs $GIT_COMMON_DIR"
business.

The redirection is done by git_path(), git_pathdup() and
strbuf_git_path(). The selected list of paths goes to $GIT_COMMON_DIR,
not the other way around in case a developer adds a new
worktree-specific file and it's accidentally promoted to be shared
across repositories (this includes unknown files added by third party
commands)

The list of known files that belong to $GIT_DIR are:

ADD_EDIT.patch BISECT_ANCESTORS_OK BISECT_EXPECTED_REV BISECT_LOG
BISECT_NAMES CHERRY_PICK_HEAD COMMIT_MSG FETCH_HEAD HEAD MERGE_HEAD
MERGE_MODE MERGE_RR NOTES_EDITMSG NOTES_MERGE_WORKTREE ORIG_HEAD
REVERT_HEAD SQUASH_MSG TAG_EDITMSG fast_import_crash_* logs/HEAD
next-index-* rebase-apply rebase-merge rsync-refs-* sequencer/*
shallow_*

Path mapping is NOT done for git_path_submodule(). Multi-checkouts are
not supported as submodules.

557bd833bb git_path(): be aware of file relocation in $GIT_DIR
We allow the user to relocate certain paths out of $GIT_DIR via
environment variables, e.g. GIT_OBJECT_DIRECTORY, GIT_INDEX_FILE and
GIT_GRAFT_FILE. Callers are not supposed to use git_path() or
git_pathdup() to get those paths. Instead they must use
get_object_directory(), get_index_file() and get_graft_file()
respectively. This is inconvenient and could be missed in review (for
example, there's git_path("objects/info/alternates") somewhere in
sha1_file.c).

This patch makes git_path() and git_pathdup() understand those
environment variables. So if you set GIT_OBJECT_DIRECTORY to /foo/bar,
git_path("objects/abc") should return /foo/bar/abc. The same is done
for the two remaining env variables.

"git rev-parse --git-path" is the wrapper for script use.

This patch kinda reverts a0279e1 (setup_git_env: use git_pathdup
instead of xmalloc + sprintf - 2014-06-19) because using git_pathdup
here would result in infinite recursion:

  setup_git_env() -> git_pathdup("objects") -> .. -> adjust_git_path()
  -> get_object_directory() -> oops, git_object_directory is NOT set
  yet -> setup_git_env()

I wanted to make git_pathdup_literal() that skips adjust_git_path().
But that won't work because later on when $GIT_COMMON_DIR is
introduced, git_pathdup_literal("objects") needs adjust_git_path() to
replace $GIT_DIR with $GIT_COMMON_DIR.

00a6fa0720 push: truly use "simple" as default, not "upstream"
The plan for the push.default transition had all along been
to use the "simple" method rather than "upstream" as a
default if the user did not specify their own push.default
value. Commit 11037ee (push: switch default from "matching"
to "simple", 2013-01-04) tried to implement that by moving
PUSH_DEFAULT_UNSPECIFIED in our switch statement to
fall-through to the PUSH_DEFAULT_SIMPLE case.

When the commit that became 11037ee was originally written,
that would have been enough. We would fall through to
calling setup_push_upstream() with the "simple" parameter
set to 1. However, it was delayed for a while until we were
ready to make the transition in Git 2.0.

And in the meantime, commit ed2b182 (push: change `simple`
to accommodate triangular workflows, 2013-06-19) threw a
monkey wrench into the works. That commit drops the "simple"
parameter to setup_push_upstream, and instead checks whether
the global "push_default" is PUSH_DEFAULT_SIMPLE. This is
right when the user has explicitly configured push.default
to simple, but wrong when we are a fall-through for the
"unspecified" case.

We never noticed because our push.default tests do not cover
the case of the variable being totally unset; they only
check the "simple" behavior itself.

4d7a5ceacc t5516: more tests for receive.denyCurrentBranch=updateInstead
The previous one tests only the case where a path to be updated by
the push-to-deploy has an incompatible change in the target's
working tree that has already been added to the index, but the
feature itself wants to require the working tree to be a lot cleaner
than what is tested.  Add a handful more tests to protect the
feature from future changes that mistakenly (from the viewpoint of
the inventor of the feature) loosens the cleanliness requirement,
namely:

 - A change only to the working tree but not to the index is still a
   change to be protected;

 - An untracked file in the working tree that would be overwritten
   by a push-to-deploy needs to be protected;

 - A change that happens to make a file identical to what is being
   pushed is still a change to be protected (i.e. the feature's
   cleanliness requirement is more strict than that of checkout).

Also, test that a stat-only change to the working tree is not a
reason to reject a push-to-deploy.

8d81408435 git-send-email: add --transfer-encoding option
The thread at http://thread.gmane.org/gmane.comp.version-control.git/257392
details problems when applying patches with "git am" in a repository with
CRLF line endings.  In the example in the thread, the repository originated
from "git-svn" so it is not possible to use core.eol and friends on it.

Right now, the best option is to use "git am --keep-cr".  However, when
a patch create new files, the patch application process will reject the
new file because it finds a "/dev/null\r" string instead of "/dev/null".

The problem is that SMTP transport is CRLF-unsafe.  Sending a patch by
email is the same as passing it through "dos2unix | unix2dos".  The newly
introduced CRLFs are normally transparent because git-am strips them. The
keepcr=true setting preserves them, but it is mostly working by chance
and it would be very problematic to have a "git am" workflow in a
repository with mixed LF and CRLF line endings.

The MIME solution to this is the quoted-printable transfer enconding.
This is not something that we want to enable by default, since it makes
received emails horrible to look at.  However, it is a very good match
for projects that store CRLF line endings in the repository.

The only disadvantage of quoted-printable is that quoted-printable
patches fail to apply if the maintainer uses "git am --keep-cr".  This
is because the decoded patch will have two carriage returns at the end
of the line.  Therefore, add support for base64 transfer encoding too,
which makes received emails downright impossible to look at outside
a MUA, but really just works.

The patch covers all bases, including users that still live in the late
80s, by also providing a 7bit content transfer encoding that refuses
to send emails with non-ASCII character in them.  And finally, "8bit"
will add a Content-Transfer-Encoding header but otherwise do nothing.

bba5fccc03 t5000 on Windows: do not mistake "sh.exe" as "sh"
In their effort to emulate POSIX as close as possible, the MSYS tools
and Cygwin treat the file name "foo.exe" as "foo" when the latter is
asked for, but not present, but the former is present.

Following this rule, 'cp /bin/sh a/bin' actually copies the file
/bin/sh.exe, so that we now have a/bin/sh.exe in the repository. This
difference did not matter in the tests in the past because we were only
interested in the equality of contents generated in various ways. But
recently added tests check file names, in particular, the presence of
"a/bin/sh". This test fails on Windows, as we do not have a file by this
name, but "a/bin/sh.exe".

Use test-genrandom to generate the large binary file in the repository
under the expected name.

We could change the guilty line to 'cat /bin/sh >a/bin/sh', but it is
better for test reproducibility to ensure that the test data is the same
across platforms, which test-genrandom can guarantee.

53de742470 t/README: justify why "! grep foo" is sufficient
We require use of test_must_fail to check expected non-zero exit by
Git itself, but discourage test_must_fail to be used for checking
exit status of non Git commands that are supplied by the system.
The current text explains the reason for the former but not the
latter.

1d31e5a2cd add: ignore only ignored files
"git add foo bar" adds neither foo nor bar when bar is ignored, but dies
to let the user recheck their command invocation. This becomes less
helpful when "git add foo.*" is subject to shell expansion and some of
the expanded files are ignored.

"git add --ignore-errors" is supposed to ignore errors when indexing
some files and adds the others. It does ignore errors from actual
indexing attempts, but does not ignore the error "file is ignored" as
outlined above. This is unexpected.

Change "git add foo bar" to add foo when bar is ignored, but issue
a warning and return a failure code as before the change.

That is, in the case of trying to add ignored files we now act the same
way (with or without "--ignore-errors") in which we act for more
severe indexing errors when "--ignore-errors" is specified.

ff40d185d2 parse_color: recognize "no$foo" to clear the $foo attribute
You can turn on ANSI text attributes like "reverse" by
putting "reverse" in your color spec. However, you cannot
ask to turn reverse off.

For common cases, this does not matter. You would turn on
"reverse" at the start of a colored section, and then clear
all attributes with a "reset". However, you may wish to turn
on some attributes, then selectively disable others. For
example:

  git log --format="%C(bold ul yellow)%h%C(noul) %s"

underlines just the hash, but without the need to re-specify
the rest of the attributes. This can also help third-party
programs, like contrib/diff-highlight, that want to turn
some attribute on/off without disrupting existing coloring.

Note that some attribute specifications are probably
nonsensical (e.g., "bold nobold"). We do not bother to flag
such constructs, and instead let the terminal sort it out.

880ef58b3d t960[34]: mark cvsimport tests as requiring perl
Git-cvsimport is written in perl, which understandably
causes the tests to fail if you build with NO_PERL (which
will avoid building cvsimport at all). The earlier cvsimport
tests in t9600-t9602 are all marked with a PERL
prerequisite, but these ones are not.

The one in t9603 was likely not noticed because it is an
expected failure anyway.

The ones in t9604 have been around for a long time, but it
is likely that the combination of NO_PERL and having cvsps
installed is rare enough that nobody noticed.

1f32ecffd8 create_default_files(): don't set u+x bit on $GIT_DIR/config
Since time immemorial, the test of whether to set "core.filemode"
has been done by trying to toggle the u+x bit on $GIT_DIR/config,
which we know always exists, and then testing whether the change
"took".  I find it somewhat odd to use the config file for this
test, but whatever.

The test code didn't set the u+x bit back to its original state
itself, instead relying on the subsequent call to git_config_set()
to re-write the config file with correct permissions.

But ever since

    daa22c6f8d config: preserve config file permissions on edits (2014-05-06)

git_config_set() copies the permissions from the old config file to
the new one.  This is a good change in and of itself, but it
invalidates the create_default_files()'s assumption, causing "git
init" to leave the executable bit set on $GIT_DIR/config.

Reset the permissions on $GIT_DIR/config when we are done with the
test in create_default_files().

d37239536c approxidate: allow ISO-like dates far in the future
When we are parsing approxidate strings and we find three
numbers separate by one of ":/-.", we guess that it may be a
date. We feed the numbers to match_multi_number, which
checks whether it makes sense as a date in various orderings
(e.g., dd/mm/yy or mm/dd/yy, etc).

One of the checks we do is to see whether it is a date more
than 10 days in the future. This was added in 38035cf (date
parsing: be friendlier to our European friends.,
2006-04-05), and lets us guess that if it is currently April
2014, then "10/03/2014" is probably March 10th, not October
3rd.

This has a downside, though; if you want to be overly
generous with your "--until" date specification, we may
wrongly parse "2014-12-01" as "2014-01-12" (because the
latter is an in-the-past date). If the year is a future year
(i.e., both are future dates), it gets even weirder. Due to
the vagaries of approxidate, months _after_ the current date
(no matter the year) get flipped, but ones before do not.

This patch drops the "in the future" check for dates of this
form, letting us treat them always as yyyy-mm-dd, even if
they are in the future. This does not affect the normal
dd/mm/yyyy versus mm/dd/yyyy lookup, because this code path
only kicks in when the first number is greater than 70
(i.e., it must be a year, and cannot be either a date or a
month).

The one possible casualty is that "yyyy-dd-mm" is less
likely to be chosen over "yyyy-mm-dd". That's probably OK,
though because:

  1. The difference happens only when the date is in the
     future. Already we prefer yyyy-mm-dd for dates in the
     past.

  2. It's unclear whether anybody even uses yyyy-dd-mm
     regularly. It does not appear in lists of common date
     formats in Wikipedia[1,2].

  3. Even if (2) is wrong, it is better to prefer ISO-like
     dates, as that is consistent with what we use elsewhere
     in git.

c5326bd62b checkout $tree: do not throw away unchanged index entries
When we "git checkout $tree", we pull paths from $tree into
the index, and then check the resulting entries out to the
worktree. Our method for the first step is rather
heavy-handed, though; it clobbers the entire existing index
entry, even if the content is the same. This means we lose
our stat information, leading checkout_entry to later
rewrite the entire file with identical content.

Instead, let's see if we have the identical entry already in
the index, in which case we leave it in place. That lets
checkout_entry do the right thing. Our tests cover two
interesting cases:

  1. We make sure that a file which has no changes is not
     rewritten.

  2. We make sure that we do update a file that is unchanged
     in the index (versus $tree), but has working tree
     changes. We keep the old index entry, and
     checkout_entry is able to realize that our stat
     information is out of date.

aae828b911 t1410: fix breakage on case-insensitive filesystems
Two tests recently added to t1410 create branches "a" and
"a/b" to test d/f conflicts on reflogs. Earlier, unrelated
tests in that script create the path "A/B" in the working
tree.  There's no conflict on a case-sensitive filesystem,
but on a case-insensitive one, "git log" will complain that
"a/b" is both a revision and a working tree path.

We could fix this by using a "--" to disambiguate, but we
are probably better off using names that are less confusing
to make it more clear that they are unrelated to the working
tree files.  This patch turns "a/b" into "one/two".

9233887cce ignore stale directories when checking reflog existence
When we update a ref, we have two rules for whether or not
we actually update the reflog:

  1. If the reflog already exists, we will always append to
     it.

  2. If log_all_ref_updates is set, we will create a new
     reflog file if necessary.

We do the existence check by trying to open the reflog file,
either with or without O_CREAT (depending on log_all_ref_updates).
If it fails, then we check errno to see what happened.

If we were not using O_CREAT and we got ENOENT, the file
doesn't exist, and we return success (there isn't a reflog
already, and we were not told to make a new one).

If we get EISDIR, then there is likely a stale directory
that needs to be removed (e.g., there used to be "foo/bar",
it was deleted, and the directory "foo" was left. Now we
want to create the ref "foo"). If O_CREAT is set, then we
catch this case, try to remove the directory, and retry our
open. So far so good.

But if we get EISDIR and O_CREAT is not set, then we treat
this as any other error, which is not right. Like ENOENT,
EISDIR is an indication that we do not have a reflog, and we
should silently return success (we were not told to create
it). Instead, the current code reports this as an error, and
we fail to update the ref at all.

Note that this is relatively unlikely to happen, as you
would have to have had reflogs turned on, and then later
turned them off (it could also happen due to a bug in fetch,
but that was fixed in the previous commit). However, it's
quite easy to fix: we just need to treat EISDIR like ENOENT
for the non-O_CREAT case, and silently return (note that
this early return means we can also simplify the O_CREAT
case).

Our new tests cover both cases (O_CREAT and non-O_CREAT).
The first one already worked, of course.

72549dfd5d fetch: load all default config at startup
When we start the git-fetch program, we call git_config to
load all config, but our callback only processes the
fetch.prune option; we do not chain to git_default_config at
all.

This means that we may not load some core configuration
which will have an effect. For instance, we do not load
core.logAllRefUpdates, which impacts whether or not we
create reflogs in a bare repository.

Note that I said "may" above. It gets even more exciting. If
we have to transfer actual objects as part of the fetch,
then we call fetch_pack as part of the same process. That
function loads its own config, which does chain to
git_default_config, impacting global variables which are
used by the rest of fetch. But if the fetch is a pure ref
update (e.g., a new ref which is a copy of an old one), we
skip fetch_pack entirely. So we get inconsistent results
depending on whether or not we have actual objects to
transfer or not!

Let's just load the core config at the start of fetch, so we
know we have it (we may also load it again as part of
fetch_pack, but that's OK; it's designed to be idempotent).

Our tests check both cases (with and without a pack). We
also check similar behavior for push for good measure, but
it already works as expected.

fa137f67a4 lockfile.c: store absolute path
Locked paths can be saved in a linked list so that if something wrong
happens, *.lock are removed. For relative paths, this works fine if we
keep cwd the same, which is true 99% of time except:

- update-index and read-tree hold the lock on $GIT_DIR/index really
  early, then later on may call setup_work_tree() to move cwd.

- Suppose a lock is being held (e.g. by "git add") then somewhere
  down the line, somebody calls real_path (e.g. "link_alt_odb_entry"),
  which temporarily moves cwd away and back.

During that time when cwd is moved (either permanently or temporarily)
and we decide to die(), attempts to remove relative *.lock will fail,
and the next operation will complain that some files are still locked.

Avoid this case by turning relative paths to absolute before storing
the path in "filename" field.

261f315beb merge & sequencer: turn "Conflicts:" hint into a comment
Just like other hints such as "Changes to be committed" we show in
the editor to remind the committer what paths were involved in the
resulting commit to help improving their log message, this section
is merely a reminder.

Traditionally, it was not made into comments primarily because it
has to be generated outside the wt-status infrastructure, and also
because it was meant as a bit stronger reminder than the others
(i.e. explaining how you resolved conflicts is much more important
than mentioning what you did to every paths involved in the commit).

d55aeb7687 strbuf_add_commented_lines(): avoid SP-HT sequence in commented lines
The strbuf_add_commented_lines() function passes a pair of prefixes,
one to be used for a non-empty line, and the other for an empty
line, to underlying add_lines().  The former is set to a comment
char followed by a SP, while the latter is set to just the comment
char.  This is designed to give a SP after the comment character,
e.g. "# <user text>\n", on a line with some text, and to avoid
emitting an unsightly "# \n" for an empty line.

Teach this machinery to also use the latter space-less prefix when
the payload line begins with a tab, to show e.g. "#\t<user text>\n";
otherwise we will end up showing "# \t<user text>\n" which is
similarly unsightly.

6936b5859c diff -B -M: fix output for "copy and then rewrite" case
Starting from a single file, A, if you create B as a copy of A (and
possibly make some edit) and then make extensive change to A, you
will see:

    $ git diff -C --name-status
    C89    A    B
    M      A

which is expected.  However, if you ask the same question in a
different way, you see this:

    $ git diff -B -M --name-status
    R89    A    B
    M100   A

telling us that A was rename-edited into B (as if "A will no longer
exist as the result") and at the same time A itself was extensively
edited.

In this case, because the resulting tree still does have file A
(even if it has contents vastly different from the original), we
should use "C"opy, not "R"ename, to avoid hinting that A somehow
goes away.

Two existing tests were depending on the wrong behaviour, and fixed.

2113471478 pack-objects: turn off bitmaps when we split packs
If a pack.packSizeLimit is set, we may split the pack data
across multiple packfiles. This means we cannot generate
.bitmap files, as they require that all of the reachable
objects are in the same pack. We check that condition when
we are generating the list of objects to pack (and disable
bitmaps if we are not packing everything), but we forgot to
update it when we notice that we needed to split (which
doesn't happen until the actual write phase).

The resulting bitmaps are quite bogus (they mention entries
that do not exist in the pack!) and can cause a fetch or
push to send insufficient objects.

c90f9e13ab repack: pack objects mentioned by the index
When we pack all objects, we use only the objects reachable
from references and reflogs. This misses any objects which
are reachable from the index, but not yet referenced.

By itself this isn't a big deal; the objects can remain
loose until they are actually used in a commit. However, it
does create a problem when we drop packed but unreachable
objects. We try to optimize out the writing of objects that
we will immediately prune, which means we must follow the
same rules as prune in determining what is reachable. And
prune uses the index for this purpose.

This is rather uncommon in practice, as objects in the index
would not usually have been packed in the first place. But
it could happen in a sequence like:

  1. You make a commit on a branch that references blob X.

  2. You repack, moving X into the pack.

  3. You delete the branch (and its reflog), so that X is
     unreferenced.

  4. You "git add" blob X so that it is now referenced only
     by the index.

  5. You repack again with git-gc. The pack-objects we
     invoke will see that X is neither referenced nor
     recent and not bother loosening it.

It's not unreasonable to have a tag that points to a blob
that is not part of the normal history. We do this in
git.git to distribute gpg keys. However, we never explicitly
checked in our test suite that this actually works (i.e.,
that pack-objects actually sends the blob because of the tag
mentioning it).

It does in fact work fine, but a recent patch under
discussion broke this, and the test suite didn't notice.

33d4221c79 write_sha1_file: freshen existing objects
When we try to write a loose object file, we first check
whether that object already exists. If so, we skip the
write as an optimization. However, this can interfere with
prune's strategy of using mtimes to mark files in progress.

For example, if a branch contains a particular tree object
and is deleted, that tree object may become unreachable, and
have an old mtime. If a new operation then tries to write
the same tree, this ends up as a noop; we notice we
already have the object and do nothing. A prune running
simultaneously with this operation will see the object as
old, and may delete it.

We can solve this by "freshening" objects that we avoid
writing by updating their mtime. The algorithm for doing so
is essentially the same as that of has_sha1_file. Therefore
we provide a new (static) interface "check_and_freshen",
which finds and optionally freshens the object. It's trivial
to implement freshening and simple checking by tweaking a
single parameter.

abcb86553d pack-objects: match prune logic for discarding objects
A recent commit taught git-prune to keep non-recent objects
that are reachable from recent ones. However, pack-objects,
when loosening unreachable objects, tries to optimize out
the write in the case that the object will be immediately
pruned. It now gets this wrong, since its rule does not
reflect the new prune code (and this can be seen by running
t6501 with a strategically placed repack).

Let's teach pack-objects similar logic.

d3038d22f9 prune: keep objects reachable from recent objects
Our current strategy with prune is that an object falls into
one of three categories:

  1. Reachable (from ref tips, reflogs, index, etc).

  2. Not reachable, but recent (based on the --expire time).

  3. Not reachable and not recent.

We keep objects from (1) and (2), but prune objects in (3).
The point of (2) is that these objects may be part of an
in-progress operation that has not yet updated any refs.

However, it is not always the case that objects for an
in-progress operation will have a recent mtime. For example,
the object database may have an old copy of a blob (from an
abandoned operation, a branch that was deleted, etc). If we
create a new tree that points to it, a simultaneous prune
will leave our tree, but delete the blob. Referencing that
tree with a commit will then work (we check that the tree is
in the object database, but not that all of its referred
objects are), as will mentioning the commit in a ref. But
the resulting repo is corrupt; we are missing the blob
reachable from a ref.

One way to solve this is to be more thorough when
referencing a sha1: make sure that not only do we have that
sha1, but that we have objects it refers to, and so forth
recursively. The problem is that this is very expensive.
Creating a parent link would require traversing the entire
object graph!

Instead, this patch pushes the extra work onto prune, which
runs less frequently (and has to look at the whole object
graph anyway). It creates a new category of objects: objects
which are not recent, but which are reachable from a recent
object. We do not prune these objects, just like the
reachable and recent ones.

This lets us avoid the recursive check above, because if we
have an object, even if it is unreachable, we should have
its referent. We can make a simple inductive argument that
with this patch, this property holds (that there are no
objects with missing referents in the repository):

  0. When we have no objects, we have nothing to refer or be
     referred to, so the property holds.

  1. If we add objects to the repository, their direct
     referents must generally exist (e.g., if you create a
     tree, the blobs it references must exist; if you create
     a commit to point at the tree, the tree must exist).
     This is already the case before this patch. And it is
     not 100% foolproof (you can make bogus objects using
     `git hash-object`, for example), but it should be the
     case for normal usage.

     Therefore for any sequence of object additions, the
     property will continue to hold.

  2. If we remove objects from the repository, then we will
     not remove a child object (like a blob) if an object
     that refers to it is being kept. That is the part
     implemented by this patch.

     Note, however, that our reachability check and the
     actual pruning are not atomic. So it _is_ still
     possible to violate the property (e.g., an object
     becomes referenced just as we are deleting it). This
     patch is shooting for eliminating problems where the
     mtimes of dependent objects differ by hours or days,
     and one is dropped without the other. It does nothing
     to help with short races.

Naively, the simplest way to implement this would be to add
all recent objects as tips to the reachability traversal.
However, this does not perform well. In a recently-packed
repository, all reachable objects will also be recent, and
therefore we have to look at each object twice. This patch
instead performs the reachability traversal, then follows up
with a second traversal for recent objects, skipping any
that have already been marked.

fb1d6dabce clone: --dissociate option to mark that reference is only temporary
While use of the --reference option to borrow objects from an
existing local repository of the same project is an effective way to
reduce traffic when cloning a project over the network, it makes the
resulting "borrowing" repository dependent on the "borrowed"
repository.  After running

	git clone --reference=P $URL Q

the resulting repository Q will be broken if the borrowed repository
P disappears.

The way to allow the borrowed repository to be removed is to repack
the borrowing repository (i.e. run "git repack -a -d" in Q); while
power users may know it very well, it is not easily discoverable.

Teach a new "--dissociate" option to "git clone" to run this
repacking for the user.

d0f810f0bc refs.c: allow listing and deleting badly named refs
We currently do not handle badly named refs well:

  $ cp .git/refs/heads/master .git/refs/heads/master.....@\*@\\.
  $ git branch
    fatal: Reference has invalid format: 'refs/heads/master.....@*@\.'
  $ git branch -D master.....@\*@\\.
    error: branch 'master.....@*@\.' not found.

Users cannot recover from a badly named ref without manually finding
and deleting the loose ref file or appropriate line in packed-refs.
Making that easier will make it easier to tweak the ref naming rules
in the future, for example to forbid shell metacharacters like '`'
and '"', without putting people in a state that is hard to get out of.

So allow "branch --list" to show these refs and allow "branch -d/-D"
and "update-ref -d" to delete them.  Other commands (for example to
rename refs) will continue to not handle these refs but can be changed
in later patches.

Details:

In resolving functions, refuse to resolve refs that don't pass the
git-check-ref-format(1) check unless the new RESOLVE_REF_ALLOW_BAD_NAME
flag is passed.  Even with RESOLVE_REF_ALLOW_BAD_NAME, refuse to
resolve refs that escape the refs/ directory and do not match the
pattern [A-Z_]* (think "HEAD" and "MERGE_HEAD").

In locking functions, refuse to act on badly named refs unless they
are being deleted and either are in the refs/ directory or match [A-Z_]*.

Just like other invalid refs, flag resolved, badly named refs with the
REF_ISBROKEN flag, treat them as resolving to null_sha1, and skip them
in all iteration functions except for for_each_rawref.

Flag badly named refs (but not symrefs pointing to badly named refs)
with a REF_BAD_NAME flag to make it easier for future callers to
notice and handle them specially.  For example, in a later patch
for-each-ref will use this flag to detect refs whose names can confuse
callers parsing for-each-ref output.

In the transaction API, refuse to create or update badly named refs,
but allow deleting them (unless they try to escape refs/ and don't match
[A-Z_]*).

62a2d52514 branch -d: avoid repeated symref resolution
If a repository gets in a broken state with too much symref nesting,
it cannot be repaired with "git branch -d":

 $ git symbolic-ref refs/heads/nonsense refs/heads/nonsense
 $ git branch -d nonsense
 error: branch 'nonsense' not found.

Worse, "git update-ref --no-deref -d" doesn't work for such repairs
either:

 $ git update-ref -d refs/heads/nonsense
 error: unable to resolve reference refs/heads/nonsense: Too many levels of symbolic links

Fix both by teaching resolve_ref_unsafe a new RESOLVE_REF_NO_RECURSE
flag and passing it when appropriate.

Callers can still read the value of a symref (for example to print a
message about it) with that flag set --- resolve_ref_unsafe will
resolve one level of symrefs and stop there.

014e7db3f5 reflog test: test interaction with detached HEAD
A proposed patch produced broken HEAD reflog entries when checking out
anything other than a branch.  The testsuite still passed, so it took
a few days for the bug to be noticed.

Add tests checking the content of the reflog after detaching and
reattaching HEAD so we don't have to rely on manual testing to catch
such problems in the future.

[jn: using 'log -g --format=%H' instead of parsing --oneline output,
 resetting state in each test so they can be safely reordered or
 skipped]

2b2b1e4d27 mv test: recreate mod/ directory instead of relying on stale copy
The tests for 'git mv moves a submodule' functionality often run
commands like

	git mv sub mod/sub

to move a submodule into a subdirectory.  Just like plain /bin/mv,
this is supposed to succeed if the mod/ parent directory exists
and fail if it doesn't exist.

Usually these tests mkdir the parent directory beforehand, but some
instead rely on it being left behind by previous tests.

More precisely, when 'git reset --hard' tries to move to a state where
mod/sub is not present any more, it would perform the following
operations:

	rmdir("mod/sub")
	rmdir("mod")

The first fails with ENOENT because the test script removed mod/sub
with "rm -rf" already, so 'reset --hard' doesn't bother to move on to
the second, and the mod/ directory is kept around.

Better to explicitly remove and re-create the mod/ directory so later
tests don't have to depend on the directory left behind by the earlier
ones at all (making it easier to rearrange or skip some tests in the
file or to tweak 'reset --hard' behavior without breaking unrelated
tests).

Noticed while testing a patch that fixes the reset --hard behavior
described above.

05e73682cd checkout: report upstream correctly even with loosely defined branch.*.merge
When checking out a branch that is set to build on top of another
branch (often, a remote-tracking branch), "git checkout" reports how
your work relates to the other branch, e.g.

    Your branch is behind 'origin/master', and can be fast-forwarded.

Back when this feature was introduced, this was only done for
branches that build on remote-tracking branches, but 5e6e2b48 (Make
local branches behave like remote branches when --tracked,
2009-04-01) added support to give the same report for branches that
build on other local branches (i.e. branches whose branch.*.remote
variables are set to '.').  Unlike the support for the branches
building on remote-tracking branches, however, this did not take
into account the fact that branch.*.merge configuration is allowed
to record a shortened branch name.

When branch.*.merge is set to 'master' (not 'refs/heads/master'),
i.e. "my branch builds on the local 'master' branch", this caused
"git checkout" to report:

    Your branch is based on 'master', but the upstream is gone.

The upstream is our repository and is definitely not gone, so this
output is nonsense.

The fix is fairly obvious; just like the branch name is DWIMed when
"git pull" merges from the 'master' branch without complaint on such
a branch, the name of the branch the current branch builds upon
needs to be DWIMed the same way.

a136f6d8ff test-lib.sh: support -x option for shell-tracing
Usually running a test under "-v" makes it clear which
command is failing. However, sometimes it can be useful to
also see a complete trace of the shell commands being run in
the test. You can do so without any support from the test
suite by running "sh -x tXXXX-foo.sh". However, this
produces quite a large bit of output, as we see a trace of
the entire test suite.

This patch instead introduces a "-x" option to the test
scripts (i.e., "./tXXXX-foo.sh -x"). When enabled, this
turns on "set -x" only for the tests themselves. This can
still be a bit verbose, but should keep things to a more
manageable level. You can even use "--verbose-only" to see
the trace only for a specific test.

The implementation is a little invasive. We turn on the "set
-x" inside the "eval" of the test code. This lets the eval
itself avoid being reported in the trace (which would be
long, and redundant with the verbose listing we already
showed). And then after the eval runs, we do some trickery
with stderr to avoid showing the "set +x" to the user.

We also show traces for test_cleanup functions (since they
can impact the test outcome, too). However, we do avoid
running the noop ":" cleanup (the default if the test does
not use test_cleanup at all), as it creates unnecessary
noise in the "set -x" output.

sha1_pos() dies and reports that the lower and upper limits of the

is wrong because the remaining two bytes could still differ.

Furthermore: It wouldn't be a problem if they actually were the same,
i.e. if all entries have the same SHA1.  The code already handles
