core.abbrevguard: Ensure short object names stay unique a bit longer
Even though git makes sure that it uses enough hexdigits to show an
abbreviated object name unambiguously, as more objects are added to the
repository over time, a short name that used to be unique will stop being
unique. Git uses this many extra hexdigits that are more than necessary
to make the object name currently unique, in the hope that its output will
stay unique a bit longer.
When git checkout -p from the index or HEAD is run in edit mode, the

make pack-objects a bit more resilient to repo corruption
Right now, packing valid objects could fail when creating a thin pack
simply because a pack edge object used as a preferred base is corrupted.
Since preferred base objects are not strictly needed to produce a valid
pack, let's not consider the inability to read them as a fatal error.
Delta compression may well be attempted against other objects in the
search window. To avoid warning storms (we are in the inner loop of
the delta search window) a warning is emitted only on the first
occurrence.

The git_config() function signals error by returning -1 in
two instances:
1. An actual error occurs in opening a config file (parse
errors cause an immediate die).
2. Of the three possible config files, none was found.
However, this second case is often not an error at all; it
simply means that the user has no configuration (they are
outside a repo, and they have no ~/.gitconfig file). This
can lead to confusing errors, such as when the bash
completion calls "git config --list" outside of a repo. If
the user has a ~/.gitconfig, the command completes
succesfully; if they do not, it complains to stderr.
This patch allows callers of git_config to distinguish
between the two cases. Error is signaled by -1, and
otherwise the return value is the number of files parsed.
This means that the traditional "git_config(...) < 0" check
for error should work, but callers who want to know whether
we parsed any files or not can still do so.

For terminal tests that capture output/stderr, the TTY prerequisite
warning does not quite work for commands like
test_terminal foo >out 2>err
because the warning gets "swallowed" up by the redirection that's
supposed only to be done by the subcommand.
Even worse, the outcome depends on whether stdout was already a
terminal (in which case test_terminal is a noop) or not (in which case
test_terminal introduces a pseudo-tty in the middle of the pipeline).
- use the test_terminal script even when running with "-v".
- skip tests that require a terminal when the test_terminal
script is unusable because IO::Pty is not installed.
- write the "need to declare TTY prerequisite" message to fd 4,
where it will be printed when running tests with -v, rather

send-pack: avoid redundant "pack-objects died with strange error"
Saying "pack-objects died with strange error" after "pack-objects died

introduced when the run-command API changed to report abnormal exits
on behalf of the caller (v1.6.5-rc0~86^2~5, 2009-07-04).
Similarly, after a controlled pack-objects failure (detectable as a
normal exit with nonzero status), a "died with strange error" message
would be redundant next to the message from pack-objects itself.
So leave off the "strange error" messages.
The result should look something like this:
$ git push sf master
Counting objects: 21542, done.
Compressing objects: 100% (4179/4179), done.
fatal: Unable to create temporary file: Permission denied

Point in many directions in the hope of helping the reader find what
is needed more quickly.
This commit also removes the summary attached to the SEE ALSO entry
for difftool, to avoid making the SEE ALSO list too verbose. If the
reader wants a summary of the commands referred to, she can always
look to the top of the named pages or to the table of contents on the
main git(1) page.

The code paths for showing commits in "git log" and "git
rev-list --graph" correctly handle embedded NULs by looking
only at the resulting strbuf's length, and never treating it
as a C string. The code path for regular rev-list, however,
used printf("%s"), which resulted in truncated output. This
patch uses fwrite instead, like the --graph code path.

submodule sync: Update "submodule.<name>.url" for empty directories
If a submodule directory has not been filled by "git submodule update"
yet, then "git submodule sync" must still update the super-project's
configuration for submodule.<name>.url.
This situation occurs when switching between branches with a module from
different urls and other branches without the submodule.

apply: Recognize epoch timestamps with : in the timezone
Some patches have a timezone formatted like ‘-08:00’ instead of
‘-0800’ (e.g. http://lwn.net/Articles/131729/), so git apply would
fail to recognize the epoch timestamp of deleted files and would
create empty files instead. Teach it to support both formats, and add
a test case.

completion: Support the DWIM mode for git checkout
Ever since commit 70c9ac2 (DWIM: "git checkout frotz" to "git checkout
-b frotz origin/frotz"), git checkout has supported a DWIM mode where
it creates a local tracking branch for a remote branch if just the name
of the remote branch is specified on the command-line and only one remote
has a branch with that name. Teach the bash completion script to understand
this DWIM mode and provide such remote-tracking branch names as possible
completions.

This remote helper invokes external command and passes raw smart transport
stream through it. This is useful for instance for invoking ssh with
one-off odd options, connecting to git services in unix domain
sockets, in abstract namespace, using TLS or other secure protocols,
etc...

This remote helper reflects raw smart remote transport stream back to the
calling program. This is useful for example if some UI wants to handle
ssh itself and not use hacks via GIT_SSH.

v1.7.3-rc0~75^2 (Teach fast-import to import subtrees named by tree id,
2010-06-30) has a shortcoming - it doesn't allow the root to be set.
Extend this behaviour by allowing the root to be referenced as the
empty path, "".
For a command (like filter-branch --subdirectory-filter) that wants
to commit a lot of trees that already exist in the object db, writing
undeltified objects as loose files only to repack them later can
involve a significant amount of overhead.
(23% slow-down observed on Linux 2.6.35, worse on Mac OS X 10.6)
Fortunately we have fast-import (which is one of the only git commands
that will write to a pack directly) but there is not an advertised way
to tell fast-import to commit a given tree without unpacking it.
This patch changes that, by allowing
M 040000 <tree id> ""
as a filemodify line in a commit to reset to a particular tree without
any need to parse it. For example,
Users can have their own pretty format aliases since 8028184 (pretty:
add aliases for pretty formats, 2010-05-02), so let's offer those
after '--pretty=' and '--format=' for 'log' and 'show', too.
Similar to the completion of aliases, this will invoke 'git config'
each time pretty aliases needs to be completed, so changes in pretty.*
configuration will be reflected immediately.

bash: support more 'git notes' subcommands and their options
The current completion function for 'git notes' only supported the
'edit' and 'show' subcommands and none of their options. This patch
adds support for all missing subcommands, options, and their arguments
(files or refs), if any.
The code responsible for completing subcommand looks different
compared to the completion functions of other git commands with
subcommands. This is because of the '--ref <notes-ref>' option which
comes before the subcommand (i.e. git notes --ref <notes-ref> add).

bisect: check for mandatory argument of 'bisect replay'
'git bisect replay' has a mandatory logfile argument, but the current
implementation doesn't check whether the user has specified one. When
the user omits the logfile argument, this leads to the following
unhelpful error message:
cannot read for replaying
So, check for the mandatory argument first, and provide a more
meaningful error message when it is omitted.

bisect: improve error msg of 'bisect reset' when original HEAD is deleted
'git bisect reset' (without the optional <commit> argument) returns to
the original HEAD from where the bisection was started. However,
when, for whatever reason, the user deleted the original HEAD before
invoking 'git bisect reset', then all he gets is an error message from
'git checkout':
fatal: invalid reference: somebranch
Let's try to be more helpful with an error message better describing
what went wrong and a suggestion about how to resolve the situation:
Could not check out original HEAD 'somebranch'. Try 'git bisect reset <commit>'.

bisect: improve error message of 'bisect log' while not bisecting
'git bisect log' is implemented by a direct invocation of 'cat
"$GIT_DIR/BISECT_LOG"', without any sanity checks. Consequently,
running 'git bisect log' while not bisecting leads to an error,
because the bisect logfile doesn't exists. The accompanying error
message
cat: /path/to/repo/.git/BISECT_LOG: No such file or directory
is neither very helpful nor very friendly.
Instead of blindly trying to cat the log file, first check whether
there is a bisection going on (i.e. the bisect logfile exists), and
die with a more appropriate error message when not.

t7607: use test-lib functions and check MERGE_HEAD
Use the test_commit and test_path_is_missing
functions from the test library.
Also make sure that a merge which fails due to
pre-merge checks aborts properly and does not
leave MERGE_HEAD behind.
The "will not overwrite removed file" test is an
exception to this. It notices the untracked file
at a stage where the merge is already well under
way. Therefore we cannot abort the merge without
major restructuring. See the following thread for
more details.
