status: refactor null_termination option

This option is passed separately to the wt_status printing
functions, whereas every other formatting option is
contained in the wt_status struct itself. Let's do the same
here, so we can avoid passing it around through the call
stack.

commit: refactor option parsing

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
further cleanups.

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

When git checkout switches from a detached HEAD to any other commit, then
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

because history beginning at HEAD is not "left behind". This makes it so.

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.

t5541: test more combinations of --progress

Previously, we tested only that "push --quiet --no-progress"

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).

teach send-pack about --[no-]progress

The send_pack function gets a "progress" flag saying "yes,
definitely show progress" or "no, definitely do not show
progress". This gets set properly by transport_push when
send_pack is called directly.

However, when the send-pack command is executed separately
(as it is for the remote-curl helper), there is no way to
tell it "definitely do this". As a result, we do not
properly respect "git push --no-progress" for smart-http
remotes; you will still get progress if stderr is a tty.

This patch teaches send-pack --progress and --no-progress,
and teaches remote-curl to pass the appropriate option to
override send-pack's isatty check. This fixes the
--no-progress case above, and as a bonus, also makes "git
push --progress" work when stderr is not a tty.

send-pack: show progress when isatty(2)

The send_pack_args struct has two verbosity flags: "quiet"
and "progress". Originally, if "quiet" was set, we would
tell pack-objects explicitly to be quiet, and if "progress"
was set, we would tell it to show progress. Otherwise, we
told it neither, and it relied on isatty(2) to make the
decision itself.

However, commit 01fdc21 changed the meaning of these
variables. Now both "quiet" and "!progress" instruct us to
tell pack-objects to be quiet (and a non-zero "progress"
means the same as before). This works well for transports
which call send_pack directly, as the transport code copies
transport->progress into send_pack_args->progress, and they
both have the same meaning.

However, the code path of calling "git send-pack" was left
behind. It always sets "progress" to 0, and thus always
tells pack-objects to be quiet. We can work around this by
checking isatty(2) ourselves in the cmd_send_pack code path,
restoring the original behavior of the send-pack command.

t5570: fix forwarding of git-daemon messages via catJohannes Sixt Thu, 26 Apr 2012 21:00:39 +0000 (23:00 +0200)

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.

docs: stop using asciidoc no-inline-literalJeff King Thu, 26 Apr 2012 08:51:57 +0000 (04:51 -0400)

docs: stop using asciidoc no-inline-literal

In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.

It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:

1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.

2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.

This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).

Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:

- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")

- some code examples used the right-arrow character
instead of '->' because they failed to quote

- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:

<tt><sub></tt> foo <tt></sub>bar</tt>

which caused some parsers to choke and omit whole
sections of the page.

- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)

- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com

- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".

- using "prime" notation like:

commit `C` and its replacement `C'`

confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes

- asciidoc got confused by the escaping of some of our
asterisks. In particular,

`credential.\*` and `credential.<url>.\*`

properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

bundle: remove stray single-quote from error message

After running rev-list --boundary to retrieve the list of boundary
commits, "git bundle create" runs its own revision walk. If in this
stage git encounters an unfamiliar option, it writes a message with an
unbalanced quotation mark:

error: unrecognized argument: --foo'

Drop the stray quote to match the "unrecognized argument: %s" message
used elsewhere and save translators some work.

This is mostly a futureproofing measure: for now, the "rev-list

above message is not seen unless you try something esoteric like "git

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.

gc: use argv-array for sub-commandsJeff King Wed, 18 Apr 2012 21:10:19 +0000 (14:10 -0700)

gc: use argv-array for sub-commands

git-gc executes many sub-commands. The argument list for
some of these is constant, but for others we add more
arguments at runtime. The latter is implemented by allocating
a constant extra number of NULLs, and either using a custom
append function, or just referencing unused slots by number.

As of commit 7e52f56, which added two new arguments, it is
possible to exceed the constant number of slots for "repack"
by running "git gc --aggressive", causing "git gc" to die.

This patch converts all of the static argv lists to use
argv-array. In addition to fixing the overflow caused by
7e52f56, it has a few advantages:

1. We can drop the custom append function (which,
incidentally, had an off-by-one error exacerbating the
static limit).

2. We can drop the ugly magic numbers used when adding
arguments to "prune".

3. Adding further arguments will be easier; you can just
add new "push" calls without worrying about increasing
any static limits.

argv-array: refactor empty_argv initialization

An empty argv-array is initialized to point to a static
empty NULL-terminated array. The original implementation
separates the actual storage of the NULL-terminator from the
pointer to the list. This makes the exposed type a "const
char **", which nicely matches the type stored by the
argv-array.

However, this indirection means that one cannot use
empty_argv to initialize a static variable, since it is
not a constant.

Instead, we can expose empty_argv directly, as an array of
pointers. The only place we use it is in the ARGV_ARRAY_INIT
initializer, and it decays to a pointer appropriately there.

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.

merge tests: octopus with redundant parents

This happens when git merge is run to merge multiple commits that are
descendants of current HEAD (or are HEAD). We've hit this while updating
master to origin/master but accidentaly we called (while being on master):

$ git merge master origin/master

Here is a minimal testcase:

$ git init a && cd a
$ echo a >a && git add a
$ git commit -minitial
$ echo b >a && git add a
$ git commit -msecond
$ git checkout master^

$ git merge master master
Fast-forwarding to: master
Already up-to-date with master
Merge made by the 'octopus' strategy.

fetch: describe new refs based on where it came from

update_local_ref() used to say "[new branch]" when we stored a new ref
outside refs/tags/ hierarchy, but the message is more about what we
fetched, so use the refname at the origin to make that decision.

Also, only call a new ref a "branch" if it's under refs/heads/.

Adjust stat width calculations to take --graph output... Lucian Poston Mon, 16 Apr 2012 10:44:51 +0000 (03:44 -0700)

Adjust stat width calculations to take --graph output into account

The recent change to compute the width of diff --stat did not take into
consideration the output from --graph. The consequence is that when both
options are used, e.g. in 'log --stat --graph', the lines are too long.

Adjust stat width calculations to take --graph output into account.

diff: avoid stack-buffer-read-overrun for very long name

Due to the use of strncpy without explicit NUL termination,
we could end up passing names n1 or n2 that are not NUL-terminated
to queue_diff, which requires NUL-terminated strings.
Ensure that each is NUL terminated.

cherry-pick: do not expect file argumentsClemens Buchacher Sat, 14 Apr 2012 19:04:48 +0000 (21:04 +0200)

cherry-pick: do not expect file arguments

If a commit-ish passed to cherry-pick or revert happens to have a file
of the same name, git complains that the argument is ambiguous and
advises to use '--'. To make things worse, the '--' argument is removed
by parse_options, und so passing '--' has no effect.

Instead, always interpret cherry-pick/revert arguments as revisions.

properly keep track of current working directoryClemens Buchacher Thu, 12 Apr 2012 23:11:36 +0000 (01:11 +0200)

properly keep track of current working directory

Various failure modes in the repository detection code path currently
quote the wrong directory in their error message. The working directory
is changed iteratively to the parent directory until a git repository is
found. If the working directory cannot be changed to the parent
directory for some reason, the detection gives up and prints an error
message. The error message should report the current working directory.

Instead of continually updating the 'cwd' variable, which is actually
used to remember the original working directory, the 'offset' variable
is used to keep track of the current working directory. At the point
where the affected error handling code is called, 'offset' already
points to the end of the parent of the working directory, rather than
the current working directory.

Fix this by explicitly using a variable 'offset_parent' and update
'offset' concurrently with the call to chdir.

In a similar fashion, the function get_device_or_die() would print the
original working directory in case of a failure, rather than the current
working directory. Fix this as well by making use of the 'offset'
variable.

Lastly, replace the phrase 'mount parent' with 'mount point'. The former
appears to be a typo.
