8338f771fe checkout: do not corrupt HEAD on empty repo
In abe1998 ("git checkout -b: allow switching out of an unborn
branch"), a code-path overly-optimisticly assumed that a
branch-name was specified. This is not always the case, and as
a result a NULL-pointer was attempted printed to .git/HEAD.

This could lead to at least two different failure modes:
 1) vsnprintf formated the NULL-string as something useful (e.g
    "(null)")
 2) vsnprintf crashed

Neither were very convenient for formatting a new HEAD-reference.

To fix this, reintroduce some strictness so we only take this
new codepath if a banch-name was specified.

d4a6bf1fb6 status: respect "-b" for porcelain format
There is no reason not to, as the user has to explicitly ask
for it, so we are not breaking compatibility by doing so. We
can do this simply by moving the "show_branch" flag into
the wt_status struct. As a bonus, this saves us from passing
it explicitly, simplifying the code.

This puts delta resolving on each base on a separate thread, one base
cache per thread. Per-thread data is grouped in struct thread_local.

5d8863954f checkout (detached): truncate list of orphaned commits at the new HEAD

all orphaned commits were listed in a warning:

  Warning: you are leaving 2 commits behind...:

But if the new commit is actually one from this list (6aa1af6 in this
example), then the list in the warning can be truncated at the new HEAD,
because history beginning at HEAD is not "left behind". This makes it so.

794151e9b5 reflog-walk: always make HEAD@{0} show indexed selectors
When we are showing reflog selectors during a walk, we infer
from context whether the user wanted to see the index in
each selector, or the reflog date. The current rules are:

  1. if the user asked for an explicit date format in the
     output, show the date

  2. if the user asked for ref@{now}, show the date

  3. if neither is true, show the index

However,  if we see "ref@{0}", that should be a strong clue
that the user wants to see the counted version. In fact, it
should be much stronger than the date format in (1). The
user may have been setting the date format to use in another
part of the output (e.g., in --format="%gd (%ad)", they may
have wanted to influence the author date).

This patch flips the rules to:

  1. if the user asked for ref@{0}, always show the index

  2. if the user asked for ref@{now}, always show the date

  3. otherwise, we have just "ref"; show them counted by
     default, but respect the presence of "--date" as a clue
     that the user wanted them date-based

f026c7563a log: respect date_mode_explicit with --format:%gd
When we show a reflog selector (e.g., via "git log -g"), we
perform some DWIM magic: while we normally show the entry's
index (e.g., HEAD@{1}), if the user has given us a date
with "--date", then we show a date-based select (e.g.,
HEAD@{yesterday}).

However, we don't want to trigger this magic if the
alternate date format we got was from the "log.date"
configuration; that is not sufficiently strong context for
us to invoke this particular magic. To fix this, commit
f4ea32f (improve reflog date/number heuristic, 2009-09-24)
introduced a "date_mode_explicit" flag in rev_info. This
flag is set only when we see a "--date" option on the
command line, and we a vanilla date to the reflog code if
the date was not explicit.

Later, commit 8f8f547 (Introduce new pretty formats %g[sdD]
for reflog information, 2009-10-19) added another way to
show selectors, and it did not respect the date_mode_explicit
flag from f4ea32f.

This patch propagates the date_mode_explicit flag to the
pretty-print code, which can then use it to pass the
appropriate date field to the reflog code. This brings the
behavior of "%gd" in line with the other formats, and means
that its output is independent of any user configuration.

7904af1c10 t1411: add more selector index/date tests
We already check that @{now} and "--date" cause the
displayed selector to use the date for both the multiline
and oneline formats. However, we miss several cases:

  1. The --format=%gd selector is not tested at all.

  2. We do not check how the log.date config interacts with the
     "--date" magic (according to f4ea32f, it should not
     impact the output).

Doing so reveals that the combination of both (log.date
combined with the %gd format) does not behave as expected.

fafd38299b log-tree: the previous one is still not quite right
The correct output would have NUL after each commit, so "-z --format=%s"
would have a single-liner subject with the line-terminating LF replaced
with NUL, and "-p/--stat -z --format=%s" would have a single-liner subject
with its line-terminating LF, followed by the diff/diffstat in which the
terminating LF of the last line is replaced with NUL, but to be consistent
with what "-p/--stat -z --pretty=format:%s" does, I think it is OK to
append NUL to the diff/diffstat part instead of replacing its last LF with
NUL.

The added test shows the update is still not right for "-p -z --format".

e304aeba20 t5541: test more combinations of --progress
Previously, we tested only that "push --quiet --no-progress"
was silent. However, there are many other combinations that
were not tested:

  1. no options at all (but stderr as a tty)
  2. --no-progress by itself
  3. --quiet by itself
  4. --progress (when stderr not a tty)

These are tested elsewhere for general "push", but it is
important to test them separately for http. It follows a
very different code path than git://, and options must be
relayed across a remote helper to a separate send-pack
process (and in fact cases (1), (2), and (4) have all been
broken just for http at some point in the past).

We can drop the "--quiet --no-progress" test, as it is not
really interesting (it is already handled by testing them
separately in (2) and (3) above).

9d7d446ae9 git p4: submit files with wildcards
There are four wildcard characters in p4.  Files with these
characters can be added to p4 repos using the "-f" option.  They
are stored in %xx notation, and when checked out, p4 converts
them back to normal.

When adding files with wildcards in git, the submit path must
be careful to use the encoded names in some places, and it
must use "-f" to add them.  All other p4 commands that operate
on the client directory expect encoded filenames as arguments.

Support for wildcards in the clone/sync path was added in
084f630 (git-p4: decode p4 wildcard characters, 2011-02-19),
but that change did not handle the submit path.

There was a problem with wildcards in the sync path too.  Commit
084f630 (git-p4: decode p4 wildcard characters, 2011-02-19)
handled files with p4 wildcards that were added or modified in
p4.  Do this for deleted files, and also in branch detection
checks, too.

The way rename works is with a "p4 integrate", optionally
followed by a "p4 edit" if the change is not a 100% rename.
Contents are generated by applying a patch, not doing a file
system rename.  Copy is similar.

In this case, p4 does not fix the permissions back to read-only.

dc801e71a7 diff --stat: use less columns for change counts
Number of columns required for change counts is now computed based on
the maximum number of changed lines instead of being fixed. This means
that usually a few more columns will be available for the filenames
and the graph.

The graph width logic is also modified to include enough space for
"Bin XXX -> YYY bytes".

If changes to binary files are mixed with changes to text files,
change counts are padded to take at least three columns. And the other
way around, if change counts require more than three columns, then
"Bin"s are padded to align with the change count. This way, the +-
part starts in the same column as "XXX -> YYY" part for binary files.
This makes the graph easier to parse visually thanks to the empty
column. This mimics the layout of diff --stat before this change.

Tests and the tutorial are updated to reflect the new --stat output.
This means either the removal of extra padding and/or the addition of
up to three extra characters to truncated filenames. One test is added
to check the graph alignment when a binary file change and text file
change of more than 999 lines are committed together.

3f8eccbe16 column: add dense layout support
Normally all cells (and in turn columns) share the same width. This
layout mode can waste space because one long item can stretch our all
columns.

With COL_DENSE enabled, column width is calculated indepdendently. All
columns are shrunk to minimum, then it attempts to push cells of the
last row over to the next column with hope that everything still fits
even there's one row less. The process is repeated until the new layout
cannot fit in given width any more, or there's only one row left
(perfect!).

Apparently, this mode consumes more cpu than the old one, but it makes
better use of terminal space. For layouting one or two screens, cpu
usage should not be detectable.

This patch introduces option handling code besides layout modes and
enable/disable to expose this feature as "dense". The feature can be

b082687cba test-lib: skip test with COLUMNS=1 under mksh
mksh does not allow $COLUMNS to be set below 12.  mksh(1) says that
$COLUMNS is "always set, defaults to 80, unless the value as reported
by stty(1) is non-zero and sane enough". This applies also to setting
it directly for one command:

    $ COLUMNS=10 python -c 'import os; print os.environ["COLUMNS"]'
    98

Add a test prerequisite by checking if we can set COLUMNS=1, to allow
us to skip tests that needs it.

7e29b8254f Add column layout skeleton and git-column
A column option string consists of many token separated by either
a space or a  comma. A token belongs to one of three groups:

 - enabling: always, never and auto
 - layout mode: currently plain (which does not layout at all)
 - other future tuning flags

git-column can be used to pipe output to from a command that wants
column layout, but not to mess with its own output code. Simpler output
code can be changed to use column layout code directly.

46e3581581 t5570: fix forwarding of git-daemon messages via cat
The shell function that starts git-daemon wants to read the first line of
the daemon's stderr to ensure that it started correctly. Subsequent daemon
errors should be redirected to fd 4 (which is the terminal in verbose mode
or /dev/null in quiet mode). To that end the shell script used 'read' to
get the first line of output, and then 'cat &' to forward everything else
in a background process.

The problem is, that 'cat >&4 &' does not produce any output because the
shell redirects a background process's stdin to /dev/null. To have this
command invocation do anything useful, we have to redirect its stdin
explicitly (which overrides the /dev/null redirection).

The shell function connects the daemon's stderr to its consumers via a
FIFO. We cannot just do this:

   read line <git_daemon_output
   cat <git_daemon_output >&4 &

because after the first redirection the pipe is closed and the daemon
could receive SIGPIPE if it writes at the wrong moment. Therefore, we open
the readable end of the FIFO only once on fd 7 in the shell and dup from
there to the stdin of the two consumers.

b55e677522 push: introduce new push.default mode "simple"
When calling "git push" without argument, we want to allow Git to do
something simple to explain and safe. push.default=matching is unsafe
when used to push to shared repositories, and hard to explain to
beginners in some contexts. It is debatable whether 'upstream' or
'current' is the safest or the easiest to explain, so introduce a new
mode called 'simple' that is the intersection of them: push to the
upstream branch, but only if it has the same name remotely. If not, give
an error that suggests the right command to push explicitely to
'upstream' or 'current'.

A question is whether to allow pushing when no upstream is configured. An
argument in favor of allowing the push is that it makes the new mode work
in more cases. On the other hand, refusing to push when no upstream is
configured encourages the user to set the upstream, which will be
beneficial on the next pull. Lacking better argument, we chose to deny
the push, because it will be easier to change in the future if someone
shows us wrong.

7fb8e163bd git-remote-testgit: fix race when spawning fast-import
Test "pushing to local repo" in t5800-remote-helpers can hang
due to a race condition in git-remote-testgit.  Fix it by
setting stdin to unbuffered.

On the writer side, "git push" invokes push_refs_with_export(),
which sends to stdout the command "export\n" and immediately
starts up "git fast-export".  The latter writes its output stream
to the same stdout.

On the reader side, remote helper "git-remote-testgit" reads from
stdin to get its next command.  It uses getc() to read characters
from libc up until \n.  Libc has buffered a potentially much
larger chunk of stdin.  When it sees the "export\n" command, it
forks "git fast-import" to read the stream.

If fast-export finishes before git fast-import starts, the
fast-export output can end up in libc's buffer in
git-remote-testgit, rather than in git fast-import.  The latter
hangs indefinitely on a now-empty stdin.

bf73fc212a difftool: print list of valid tools with '--tool-help'
Since bc7a96a (mergetool--lib: Refactor tools into separate files,

script in the '$(git --exec-path)/mergetools' directory.  Updating the
difftool help text is still a manual process, and the documentation can
easily go out of sync.

This commit teaches difftool the '--tool-help' option, which:
  - Reads the list of valid tools from 'mergetools/*'
  - Determines which of them are actually installed
  - Determines which are capable of diffing (i.e. not just a merge tool)
  - Prints the resulting list for the user

911d5da6f2 completion: fix completion after 'git --option <TAB>'
The bash completion doesn't work when certain options to git itself are
specified, e.g. 'git --no-pager <TAB>' errors out with

    error: invalid key: alias.--no-pager

The main _git() completion function finds out the git command name by
looping through all the words on the command line and searching for
the first word that is not a known option for the git command.

Unfortunately the list of known git options was not updated in a long
time, and newer options are not skipped but mistaken for a git command.
Such a misrecognized "command" is then passed to __git_aliased_command(),
which in turn passes it to a 'git config' query, hence the error.

Currently the following options are misrecognized for a git command:

  -c --no-pager --exec-path --html-path --man-path --info-path
  --no-replace-objects --work-tree= --namespace=

To fix this we could just update the list of options to be skipped,
but the same issue will likely arise, if the git command learns a new
option in the future.  Therefore, to make it more future proof against
new options, this patch changes that loop to skip all option-looking
words, i.e. words starting with a dash.

We also have to handle the '-c' option specially, because it takes a
configutation parameter in a separate word, which must be skipped,
too.

3ffcd08688 completion: avoid trailing space for --exec-path
"--exec-path" looks to the completion script like an unambiguous
successful completion, but it is wrong to emit a SP after it as if
declaring that we are done with completion; the user could be trying
to do

	git --exec-path; # print name of helper directory

or

	git --exec-path=/path/to/alternative/helper/dir <subcommand>

so the most helpful thing to do is to leave out the trailing space and
leave it to the operator to type an equal sign or carriage return
according to the situation.

05880b0222 t9300-fast-import: avoid 'exit' in test_expect_success snippets
Exiting from a for-loop early using '|| break' does not propagate the
failure code, and for this reason, the tests used just 'exit'. But this
ends the test script with 'FATAL: Unexpected exit code 1' in the case of
a failed test.

Fix this by moving the loop into a shell function, from which we can
simply return early.

While at it, modernize the style of the affected test cases.

e78cbf8cbb builtin/merge.c: reduce parents early
Instead of waiting until we record the parents of resulting merge, reduce
redundant parents (including our HEAD) immediately after reading them.

The change to t7602 illustrates the essence of the effect of this change.
The octopus merge strategy used to be fed with redundant commits only to
discard them as "up-to-date", but we no longer feed such redundant commits
to it and the affected test degenerates to a regular two-head merge.

And obviously the known-to-be-broken test in t6028 is now fixed.

17c82211ec Be more specific if upstream branch is not tracked
If the branch configured as upstream didn't have a local tracking
branch, git said "Upstream branch not found". We can be more helpful,
and separate the cases when upstream is not configured, and when it is
configured, but the upstream branch is not tracked in a local branch.

The following configuration leads to the second scenario:

    [remote "origin"]
    	    url = ...
            fetch = refs/heads/master
    [branch "master"]
            remote = origin

9884e67f9d Provide branch name in error message when using @{u}
When using @{u} or @{upstream} it is common to omit the branch name,
implying current branch. If the upstream is not configured, the error
message was "No upstream branch found for ''".

When resolving '@{u}', branch_get() is called, which almost always
returns a description of a branch. This allows us to use a branch name
in the error message, even if the user said something like '@{u}'.

The only case when branch_get() returns NULL is when HEAD points to so
something which is not a branch. Of course this also means that no
upstream is configured, but it is better to directly say that HEAD
does not point to a branch.

- check error message for branch@{u} on a branch with

  * on a branch with a configured upstream which doesn't have a
    remote-tracking branch
- check error message for branch@{u} when branch 'branch' does not
  exist
- check error message for @{u} without the branch name

Right now the messages are very similar, but various cases can and
will be distinguished.

7e52f5660e gc: do not explode objects which will be immediately pruned
When we pack everything into one big pack with "git repack
-Ad", any unreferenced objects in to-be-deleted packs are
exploded into loose objects, with the intent that they will
be examined and possibly cleaned up by the next run of "git
prune".

Since the exploded objects will receive the mtime of the
pack from which they come, if the source pack is old, those
loose objects will end up pruned immediately. In that case,
it is much more efficient to skip the exploding step
entirely for these objects.

This patch teaches pack-objects to receive the expiration
information and avoid writing these objects out. It also
teaches "git gc" to pass the value of gc.pruneexpire to
repack (which in turn learns to pass it along to
pack-objects) so that this optimization happens
automatically during "git gc" and "git gc --auto".

06804c76e8 git p4: import/export of labels to/from p4
The existing label import code looks at each commit being
imported, and then checks for labels at that commit. This
doesn't work in the real world though because it will drop
labels applied on changelists that have already been imported,
a common pattern.

This change adds a new --import-labels option. With this option,
at the end of the sync, git p4 gets sets of labels in p4 and git,
and then creates a git tag for each missing p4 label.

This means that tags created on older changelists are
still imported.

Tags that could not be imported are added to an ignore
list.

The same sets of git and p4 tags and labels can also be used to
derive a list of git tags to export to p4. This is enabled with
--export-labels in 'git p4 submit'.

7103d2543a remote-curl: main test case for the OS command line overflow
This is main test case for the original problem that triggered this
patch series. We create a repo with 50k tags and then test whether
git-clone over the smart HTTP protocol succeeds.

Note that we construct the repo in a slightly different way than the
original script used to reproduce the problem. This is because the
original script just created 50k tags all pointing to the same commit,
so if there was a bug where remote-curl.c was not passing all the refs
to fetch-pack we wouldn't know. The clone would succeed even if only one
tag was passed, because all the other tags were pointing at the same SHA
and would be considered present.

Instead we create a repo with 50k independent (dangling) commits and
then tag each of those commits with a unique tag. This way if one of the
tags is not given to fetch-pack, later stages of the clone would
complain about it.

This allows us to test both that the command line overflow was fixed, as
well as that it was fixed in a way that doesn't leave out any of the
refs.

06454cb9a3 fast-import: tighten parsing of datarefs
The syntax for the use of mark references in fast-import
demands either a SP (space) or LF (end-of-line) after
a mark reference.  Fast-import does not complain when garbage
appears after a mark reference in some cases.

Factor out parsing of mark references and complain if
errant characters are found.  Also be a little more careful
when parsing "inline" and SHA1s, complaining if extra
characters appear or if the form of the dataref is unrecognized.

Buggy input can cause fast-import to produce the wrong output,
silently, without error.  This makes it difficult to track
down buggy generators of fast-import streams.  An example is
seen in the last line of this commit command:

    commit refs/heads/S2
    committer Name <name@example.com> 1112912893 -0400
    data <<COMMIT
    commit message
    COMMIT
    from :1M 100644 :103 hello.c

It is missing a newline and should be:

    [...]
    from :1
    M 100644 :103 hello.c

What fast-import does is to produce a commit with the same
contents for hello.c as in refs/heads/S2^.  What the buggy
program was expecting was the contents of blob :103.  While
the resulting commit graph looked correct, the contents in
some commits were wrong.

dfa1725a3e fix http auth with multiple curl handles
HTTP authentication is currently handled by get_refs and fetch_ref, but
not by fetch_object, fetch_pack or fetch_alternates. In the
single-threaded case, this is not an issue, since get_refs is always
called first. It recognigzes the 401 and prompts the user for
credentials, which will then be used subsequently.

If the curl multi interface is used, however, only the multi handle used
by get_refs will have credentials configured. Requests made by other
handles fail with an authentication error.

Fix this by setting CURLOPT_USERPWD whenever a slot is requested.

a6754cda43 rebase -i continue: don't skip commits that only change submodules
When git-rebase--interactive stops due to a conflict and the only change
to be committed is in a submodule, the test for whether there is
anything to be committed ignores the staged submodule change.  This
leads rebase to skip creating the commit for the change.

While unstaged submodule changes should be ignored to avoid needing to
update submodules during a rebase, it is safe to remove the
--ignore-submodules option to diff-index because --cached ensures that
it is only checking the index.  This was discussed in [1] and a test is
included to ensure that unstaged changes are still ignored correctly.

38f865c27d run-command: treat inaccessible directories as ENOENT
When execvp reports EACCES, it can be one of two things:

  1. We found a file to execute, but did not have
     permissions to do so.

  2. We did not have permissions to look in some directory
     in the $PATH.

In the former case, we want to consider this a
permissions problem and report it to the user as such (since
getting this for something like "git foo" is likely a
configuration error).

In the latter case, there is a good chance that the
inaccessible directory does not contain anything of
interest. Reporting "permission denied" is confusing to the
user (and prevents our usual "did you mean...?" lookup). It
also prevents git from trying alias lookup, since we do so
only when an external command does not exist (not when it
exists but has an error).

This patch detects EACCES from execvp, checks whether we are
in case (2), and if so converts errno to ENOENT. This
behavior matches that of "bash" (but not of simpler shells
that use execvp more directly, like "dash").

Test stolen from Junio.

135dadef71 push: error out when the "upstream" semantics does not make sense
The user can say "git push" without specifying any refspec.  When using
the "upstream" semantics via the push.default configuration, the user
wants to update the "upstream" branch of the current branch, which is the
branch at a remote repository the current branch is set to integrate with,
with this command.

However, there are cases that such a "git push" that uses the "upstream"
semantics does not make sense:

 - The current branch does not have branch.$name.remote configured.  By
   definition, "git push" that does not name where to push to will not
   know where to push to.  The user may explicitly say "git push $there",
   but again, by definition, no branch at repository $there is set to
   integrate with the current branch in this case and we wouldn't know
   which remote branch to update.

 - The current branch does have branch.$name.remote configured, but it
   does not specify branch.$name.merge that names what branch at the
   remote this branch integrates with. "git push" knows where to push in
   this case (or the user may explicitly say "git push $remote" to tell us
   where to push), but we do not know which remote branch to update.

 - The current branch does have its remote and upstream branch configured,
   but the user said "git push $there", where $there is not the remote
   named by "branch.$name.remote".  By definition, no branch at repository
   $there is set to integrate with the current branch in this case, and
   this push is not meant to update any branch at the remote repository
   $there.

The first two cases were already checked correctly, but the third case was
not checked and we ended up updating the branch named branch.$name.merge
at repository $there, which was totally bogus.

4066bd6797 add--interactive: ignore unmerged entries in patch mode
When "add -p" sees an unmerged entry, it shows the combined
diff and then immediately skips the hunk. This can be
confusing in a variety of ways, depending on whether there
are other changes to stage (in which case you get the
superfluous combined diff output in between other hunks) or
not (in which case you get the combined diff and the program
exits immediately, rather than seeing "No changes").

The current behavior was not planned, and is just what the
implementation happens to do. Instead, let's explicitly
remove unmerged entries from our list of modified files, and
print a warning that we are ignoring them.

We can cheaply find which entries are unmerged by adding
"--raw" output to the "diff-files --numstat" we already run.
There is one non-obvious thing we must change when parsing
this combined output. Before this patch, when we saw a
numstat line for a file that did not have index changes, we
would create a new record with 'unchanged' in the 'INDEX'
field.  Because "--raw" comes before "--numstat", we must
move this special-case down to the raw-line case (and it is
sufficient to move it rather than handle it in both places,
since any file which has a --numstat will also have a --raw
entry).

e32a4581bc http-backend: respect existing GIT_COMMITTER_* variables
The http-backend program sets default GIT_COMMITTER_NAME and
GIT_COMMITTER_EMAIL variables based on the REMOTE_USER and
REMOTE_ADDR variables provided by the webserver. However, it
unconditionally overwrites any existing GIT_COMMITTER
variables, which may have been customized by site-specific
code in the webserver (or in a script wrapping http-backend).

Let's leave those variables intact if they already exist,
assuming that any such configuration was intentional. There
is a slight chance of a regression if somebody has set
GIT_COMMITTER_* for the entire webserver, not intending it
to leak through http-backend. We could protect against this
by passing the information in alternate variables.  However,
it seems unlikely that anyone will care about that
regression, and there is value in the simplicity of using
the common variable names that are used elsewhere in git.

While we're tweaking the environment-handling in
http-backend, let's switch it to use argv_array to handle
the list of variables. That makes the memory management much
simpler.

4f7cb99ada merge-recursive: don't detect renames of empty files
Merge-recursive detects renames so that if one side modifies
"foo" and the other side moves it to "bar", the modification
is applied to "bar". However, our rename detection is based
on content analysis, it can be wrong (i.e., two files were
not intended as a rename, but just happen to have the same
or similar content).

This is quite rare if the files actually contain content,
since two unrelated files are unlikely to have exactly the
same content.  However, empty files present a problem, in
that there is nothing to analyze. An uninteresting
placeholder file with zero bytes may or may not be related
to a placeholder file with another name.

The result is that adding content to an empty file may cause
confusion if the other side of a merge removed it; your
content may end up in another random placeholder file that
was added.

Let's err on the side of caution and not consider empty
files as renames. This will cause a modify/delete conflict
on the merge, which will let the user sort it out
themselves.

ae2f203ef7 clean: preserve nested git worktree in subdirectories
remove_dir_recursively() has a check to avoid removing the directory it
was asked to remove without recursing into it and report success when the
directory is the top level of a working tree of a nested git repository,
to protect such a repository from "clean -f" (without double -f). If a
working tree of a nested git repository is in a subdirectory of a toplevel
project, however, this protection did not apply by mistake; we forgot to
pass the REMOVE_DIR_KEEP_NESTED_GIT down to the recursive removal
codepath.

This requires us to also teach the higher level not to remove the
directory it is asked to remove, when the recursed invocation did not
remove the directory it was asked to remove due to a nested git
repository, as it is not an error to leave the parent directories of such
a nested repository.

dabba590aa notes-merge: Don't remove .git/NOTES_MERGE_WORKTREE; it may be the user's cwd
When a manual notes merge is committed or aborted, we need to remove the
temporary worktree at .git/NOTES_MERGE_WORKTREE. However, removing the
entire directory is not good if the user ran the 'git notes merge
--commit/--abort' from within that directory. On Windows, the directory
removal would simply fail, while on POSIX systems, users would suddenly
find themselves in an invalid current directory.

Therefore, instead of deleting the entire directory, we delete everything
_within_ the directory, and leave the (empty) directory in place.

This would cause a subsequent notes merge to abort, complaining about a
previous - unfinished - notes merge (due to the presence of
.git/NOTES_MERGE_WORKTREE), so we also need to adjust this check to only
trigger when .git/NOTES_MERGE_WORKTREE is non-empty.

Finally, adjust the t3310 manual notes merge testcases to correctly handle
the existence of an empty .git/NOTES_MERGE_WORKTREE directory.

a0be62c100 notes-merge: use opendir/readdir instead of using read_directory()
notes_merge_commit() only needs to list all entries (non-recursively)
under a directory, which can be easily accomplished with
opendir/readdir and would be more lightweight than read_directory().

read_directory() is designed to list paths inside a working
directory. Using it outside of its scope may lead to undesired effects.

Apparently, one of the undesired effects of read_directory() is that it
doesn't deal with being given absolute paths. This creates problems for
notes_merge_commit() when git_path() returns an absolute path, which
happens when the current working directory is in a subdirectory of the
.git directory.

01bfec8e52 t3310: illustrate failure to "notes merge --commit" inside $GIT_DIR/
The 'git notes merge' command expected to be run from the working
tree of the project being annotated, and did not anticipate getting
run inside $GIT_DIR/.

However, because we use $GIT_DIR/NOTES_MERGE_WORKTREE as a temporary
working space for the user to work on resolving conflicts, it is not
unreasonable for a user to run "git notes merge --commit" there. But
the command fails to do so.

The commit message which added those tests (861444f 't: add test
harness for external credential helpers' 2011-12-10) provided nice

The documentation is updated to reflect the fact that
GIT_TEST_CREDENTIAL_HELPER must be set for
GIT_TEST_CREDENTIAL_HELPER_TIMEOUT to be used
and GIT_TEST_CREDENTIAL_HELPER_SETUP can be used.

6440d3417c diff: tweak a _copy_ of diff_options with word-diff
When using word diff, the code sets the word_regex from various
defaults if it was not set already.  The problem is that it does this
on the original diff_options, which will also be used in subsequent
diffs.

This means that when the word_regex is not given on the command line,
only the first diff for which a setting for word_regex (either from
attributes or diff.wordRegex) ever takes effect.  This value then
propagates to the rest of the diff runs and in particular prevents
further attribute lookups.

Fix the problem of changing diff state once and for all, by working
with a _copy_ of the diff_options.

418a1435f1 fmt-merge-msg: show those involved in a merged series
As we already walk the history of the branch that gets merged to
come up with a short log, let's label it with names of the primary
authors, so that the user who summarizes the merge can easily give
credit to them in the log message.

Also infer the names of "lieutents" to help integrators at higher
level of the food-chain to give credit to them, by counting:

 * The committer of the 'tip' commit that is merged
 * The committer of merge commits that are merged

Often the first one gives the owner of the history being pulled, but
his last pull from his sublieutenants may have been a fast-forward,
in which case the first one would not be.  The latter rule will
count the integrator of the history, so together it might be a
reasonable heuristics.

There are two special cases:

 - The "author" credit is omitted when the series is written solely
   by the same author who is making the merge. The name can be seen
   on the "Author" line of the "git log" output to view the log
   message anyway.

 - The "lieutenant" credit is omitted when there is only one key
   committer in the merged branch and it is the committer who is
   making the merge. Typically this applies to the case where the
   developer merges his own branch.

2983c0e22a test: use numstat instead of diffstat in binary-diff test
git's --stat output is intended for humans and since v1.7.9.2~13
(2012-02-01) varies by locale.  The tests in this script using "apply
--stat" are meant to check two things:

 - how binary file changes are accounted for and printed in
   git's diffstat format

 - that "git apply" can parse the various forms of binary diff

Split these two kinds of check into separate tests, and use --numstat
instead of --stat in the latter.  This way, we lose less test coverage
when git is being run without writing its output in the C locale (for
example because GETTEXT_POISON is enabled) and there are fewer tests
to change if the --stat output needs to be tweaked again.

While at it, use commands separated by && that read and write to
temporary files in place of pipelines so segfaults and other failures
in the upstream of the processing pipeline don't get hidden.

git's diff --stat output is intended for human consumption and

that git stash show defaults to --stat and tweak the rest of the
"stash show" tests that showed a diffstat to use numstat.

This way, there are fewer tests to tweak if the diffstat format
changes again.  This also improves test coverage when running tests
with git configured not to write its output in the C locale (e.g.,
via GETTEXT_POISON=Yes).

2593633f5a test: test cherry-pick functionality and output separately
Since v1.7.3-rc0~26^2~9 (revert: report success when using option
--strategy, 2010-07-14), the cherry-pick-many-commits test checks the
format of output written to the terminal during a cherry-pick sequence
in addition to the functionality.  There is no reason those have to
be checked in the same test, though, and it has some downsides:

 - when progress output is broken, the test result does not convey
   whether the functionality was also broken or not

 - it is not immediately obvious when reading that these checks are
   meant to prevent regressions in details of the output format and
   are not just a roundabout way to check functional details like the
   number of commits produced

 - there is a temptation to include the same kind of output checking
   for every new cherry-pick test, which would make future changes
   to the output unnecessarily difficult

Put the tests from v1.7.3-rc0~26^2~9 in separate assertions, following
the principle "test one feature at a time".

ef7db1933b test: modernize funny-names test style
This is one of the early tests, so it uses a style that by modern
standards can be hard to read.  Tweak it to:

 - clearly declare what assertion each test is designed to check

 - mark tests that create state later tests will depend on with the
   word "setup" so people writing or running tests know the others
   can be skipped or reordered safely

 - put commands that populate a file with expected output inside
   the corresponding test stanza, so it is easier to see by eye
   where each test begins and ends

 - instead of pipelines, use commands that read and write a
   temporary file, so bugs causing commands to segfault or produce
   the wrong exit status can be caught.

More cosmetic changes:

 - put the opening quote starting each test on the same line as the
   test_expect_* invocation, and indent the commands in each test
   with a single tab

 - end the test early if the underlying filesystem cannot
   accomodate the filenames we use, instead of marking all tests
   with the same TABS_IN_FILENAMES prerequisite.

e7a8ac3875 test: use numstat instead of diffstat in funny-names test
This test script checks that git's plumbing commands quote filenames
with special characters like space, tab, and double-quote
appropriately in their input and output.

Since commit v1.7.9.2~13 (Use correct grammar in diffstat summary
line, 2012-02-01), the final "1 file changed, 1 insertion(+)" line
from diffstats is translatable, meaning tests that rely on exact "git
apply --stat" output have to be skipped when git is not configured to
produce output in the C locale (for example, when GETTEXT_POISON is
enabled).  So:

 - Tweak the three "git apply --stat" tests that check "git apply"'s
   input parsing to use --numstat instead.

   --numstat output is more reliable, does not vary with locale, and
   is itself easier to parse.  These tests are mainly about how "git
   apply" parses its input so this should not result in much loss of
   coverage.

 - Add a new "apply --stat" test to check the quoting in --stat output
   format.

This wins back a little of the test coverage lost with the patch
"test: use test_i18ncmp to check --stat output" when GETTEXT_POISON is
enabled.

7dfe8ad600 commit: pass author/committer info to hooks
When lying the author name via GIT_AUTHOR_NAME environment variable
to "git commit", the hooks run by the command saw it and could act
on the name that will be recorded in the final commit. When the user
uses the "--author" option from the command line, the command should
give the same information to the hook, and back when "git command"
was a scripted Porcelain, it did set the environment variable and
hooks can learn the author name from it.

However, when the command was reimplemented in C, the rewritten code
was not very faithful to the original, and hooks stopped getting the
authorship information given with "--author".  Fix this by exporting
the necessary environment variables.

178e1deaae fast-import: don't allow 'ls' of path with empty components
As the fast-import manual explains:

	The value of <path> must be in canonical form. That is it must
	not:
	. contain an empty directory component (e.g. foo//bar is invalid),
	. end with a directory separator (e.g. foo/ is invalid),
	. start with a directory separator (e.g. /foo is invalid),

Unfortunately the "ls" command accepts these invalid syntaxes and
responds by declaring that the indicated path is missing.  This is too
subtle and causes importers to silently misbehave; better to error out
so the operator knows what's happening.

The C, R, and M commands already error out for such paths.

9b9f46f5c1 t0204: clarify the "observe undefined behaviour" test
This test asks for an impossible conversion to the system by
preparing an UTF-8 translation with characters that cannot be
expressed in ISO-8859-1, and then asking the message shown in
ISO-8859-1.  Even though the behaviour against such a request is
undefined, it may be interesting to see what the system does, and
the purpose of this test is to see if there are platforms that
exhibit behaviour that we haven't seen.

The original recognized two known modes of behaviour:

 - the key used to query the message catalog ("TEST: Old English
   Runes"), saying "I cannot do that i18n".
 - impossible characters replaced with ASCII "?", saying "I punt".

but they were treated totally differently.  The test simply issued
an informational message "Your system punts on this one" for the
first error mode, while it diagnosed the latter as "Your system is
good; you pass!".

It turns out that Mac OS X exhibits a third mode of error behaviour,
to spew out the raw value stored in the message catalog.  The test
diagnosed this behaviour as "broken", but it is merely trying to do
its best to respond to an impossible request by saying "I punt" in a
way that is slightly different from the second one.

Update the offending test to make it clear what is (and is not)
being tested, update the code structure so that newly discovered
error mode can easily be added to it later, and reword the message
that comes from a failing case to clarify that it is not the system
that is broken when it fails, but merely that the behaviour is not
something we have seen.

OS X's sed and grep would complain with (respectively)

  sed: 1: "/^-/{p;q}": extra characters at the end of q command
  grep: Regular expression too big

For sed, use an explicit ; to terminate the q command.

For grep, spell the "40 hex digits" explicitly in the regex, which
should be safe as other tests already use this and we haven't got
breakage reports on OS X about them.
