completion: split __git_ps1 into a separate script

bash-completion 1.90 shipped with support to load completions
dynamically[1], which means the git completion script wouldn't be loaded
until the user types 'git <tab>'--this creates a problem to people using
__git_ps1(); that function won't be available when the shell is first
created.

For now distributions have workarounded this issue by moving the git
completion to the "compatdir"[2]; this of course is not ideal.

The solution, proposed by Kerrick Staley[3], is to split the git script
in two; the part that deals with __git_ps1() in one (i.e.
git-prompt.sh), and everything else in another (i.e.
git-completion.bash).

Another benefit of this is that zsh user that are not interested in the
bash completion can use it for their prompts, which has been tried
before[4].

The only slight issue is that __gitdir() would be duplicated, but this
is probably not a big deal.

So let's go ahead and move __git_ps1() to a new file.

While at this, I took the liberty to reformat the help text in the new
file.

checkout: do not corrupt HEAD on empty repoErik Faye-Lund Tue, 8 May 2012 17:22:33 +0000 (19:22 +0200)

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.

dir: convert to strbuf

The functions read_directory_recursive() and treat_leading_path() both
use buffers sized to fit PATH_MAX characters. The latter can be made to
overrun its buffer, e.g. like this:

$ a=0123456789abcdef
$ a=$a$a$a$a$a$a$a$a
$ a=$a$a$a$a$a$a$a$a
$ a=$a$a$a$a$a$a$a$a
$ git add $a/a

Instead of trying to add a check and potentionally forgetting to address
similar cases, convert the involved functions and their helpers to use
struct strbuf. The patch is suprisingly large because the helpers
treat_path() and treat_one_path() modify the buffer as well and thus need
to be converted, too.

status: refactor colopts handlingJeff King Mon, 7 May 2012 19:35:03 +0000 (15:35 -0400)

status: refactor colopts handling

The current code reads the config and command-line options
into a separate "colopts" variable, and then copies the
contents of that variable into the "struct wt_status". We
can eliminate the extra variable and copy just write
straight into the wt_status struct.

This simplifies the "status" code a little bit.
Unfortunately, it makes the "commit" code one line more
complex; a side effect of the separate variable was that
"commit" did not copy the colopts variable, so any
column.status configuration had no effect.

The result still ends up cleaner, though. In the previous
version, it was unclear whether commit simply forgot to copy
the colopt variable, or whether it was intentional. Now it
explicitly turns off column options. Furthermore, if commit

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.

The options are declared as a static global, but really they
need only be accessible from cmd_commit. Additionally,
declare the "struct wt_status" in cmd_commit and cmd_status
as static at the top of each function; this will let the
options lists reference them directly, which will facilitate

reflog-walk: always make HEAD@{0} show indexed selectorsJeff King Fri, 4 May 2012 05:27:25 +0000 (01:27 -0400)

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

reflog-walk: clean up "flag" field of commit_reflog... Jeff King Fri, 4 May 2012 05:26:26 +0000 (01:26 -0400)

reflog-walk: clean up "flag" field of commit_reflog struct

When we prepare to walk a reflog, we parse the specification
and pull some information from it, such as which reflog to
look in (e.g., HEAD), and where to start (e.g., HEAD@{10} or
HEAD@{yesterday}). The resulting struct has a "recno" field
to show where in the reflog we are starting. It also has a
"flag" field; if true, it means the recno field came from
parsing a date like HEAD@{yesterday}.

There are two problems with this:

1. "flag" is an absolutely terrible name, as it conveys
nothing about the meaning

2. you can tell "HEAD" from "HEAD@{yesterday}", but you
can't differentiate "HEAD" from "HEAD{0}"

This patch converts the flag into a tri-state (and gives it
a better name!).

log: respect date_mode_explicit with --format:%gdJeff King Fri, 4 May 2012 05:25:18 +0000 (01:25 -0400)

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.

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.

the NULL pointer would already have issued an error message, so simply
returning early with an error status without issuing a new message is
