In Git 2.0, "git add -u" and "git add -A" without any pathspec will
update the index for all paths, including those outside the current
directory, making it more consistent with "commit -a". To help the
migration pain, a warning is issued when the differences between the
current behaviour and the upcoming behaviour matters, i.e. when the
user has local changes outside the current directory.

pretty: support %>> that steal trailing spacesNguyễn Thái Ngọc Duy Thu, 18 Apr 2013 23:08:52 +0000 (09:08 +1000)

pretty: support %>> that steal trailing spaces

This is pretty useful in `%<(100)%s%Cred%>(20)% an' where %s does not
use up all 100 columns and %an needs more than 20 columns. By
replacing %>(20) with %>>(20), %an can steal spaces from %s.

%>> understands escape sequences, so %Cred does not stop it from
stealing spaces in %<(100).

pretty: support padding placeholders, %< %> and %><

Either %<, %> or %>< standing before a placeholder specifies how many
columns (at least as the placeholder can exceed it) it takes. Each
differs on how spaces are padded:

%< pads on the right (aka left alignment)
%> pads on the left (aka right alignment)
%>< pads both ways equally (aka centered)

The (<N>) follows them, e.g. `%<(100)', to specify the number of
columns the next placeholder takes.

However, if '|' stands before (<N>), e.g. `%>|(100)', then the number
of columns is calculated so that it reaches the Nth column on screen.

pretty: two phase conversion for non utf-8 commitsNguyễn Thái Ngọc Duy Thu, 18 Apr 2013 23:08:47 +0000 (09:08 +1000)

pretty: two phase conversion for non utf-8 commits

Always assume format_commit_item() takes an utf-8 string for string
handling simplicity (we can handle utf-8 strings, but can't with other
encodings).

If commit message is in non-utf8, or output encoding is not, then the
commit is first converted to utf-8, processed, then output converted
to output encoding. This of course only works with encodings that are
compatible with Unicode.

This also fixes the iso8859-1 test in t6006. It's supposed to create
an iso8859-1 commit, but the commit content in t6006 is in UTF-8.
t6006 is now converted back in UTF-8 (the downside is we can't put
utf-8 strings there anymore).

parse_commit_header() provides the commit encoding for '%e' and it
reads it from the re-encoded message, which contains the new encoding,
not the original one in the commit object. This never happens because
--pretty=format:xxx never respects i18n.logoutputencoding. But that's
a different story.

git add: rework the logic to warn "git add <pathspec... Junio C Hamano Wed, 17 Apr 2013 19:32:21 +0000 (12:32 -0700)

git add: rework the logic to warn "git add <pathspec>..." default change

The earlier logic to warn against "git add subdir" that is run
without "-A" or "--no-all" was only to check any <pathspec> given
exactly spells a directory name that (still) exists on the
filesystem. This had number of problems:

* "git add '*dir'" (note that the wildcard is hidden from the
shell) would not trigger the warning.

* "git add '*.py'" would behave differently between the current
version of Git and Git 2.0 for the same reason as "subdir", but
would not trigger the warning.

* "git add dir" for a submodule "dir" would just update the index
entry for the submodule "dir" without ever recursing into it, and
use of "-A" or "--no-all" would matter. But the logic only
checks the directory-ness of "dir" and gives an unnecessary
warning.

Rework the logic to detect the case where the behaviour will be
different in Git 2.0, and issue a warning only when it matters.
Even with the code before this warning, "git add subdir" will have
to traverse the directory in order to find _new_ files the index
does not know about _anyway_, so we can do this check without adding
an extra pass to find if <pathspec> matches any removed file.

This essentially updates the "add_files_to_cache()" public API to
"update_files_in_cache()" API that is internal to "git add", because
with the "--all" option, the function is no longer about "adding"
paths to the cache, but is also used to remove them.

There are other callers of the former from "checkout" (used when
"checkout -m" prepares the temporary tree that represents the local
modifications to be merged) and "commit" ("commit --include" that
picks up local changes in addition to what is in the index). Since
ADD_CACHE_IGNORE_ERRORS (aka "--no-all") is not used by either of
them, once dust settles after Git 2.0 and the warning becomes
unnecessary, we may want to unify these two functions again.

cat-file: print tags raw for "cat-file -p"Jeff King Wed, 17 Apr 2013 21:00:48 +0000 (17:00 -0400)

cat-file: print tags raw for "cat-file -p"

When "cat-file -p" prints commits, it shows them in their
raw format, since git's format is already human-readable.
For tags, however, we print the whole thing raw except for
one thing: we convert the timestamp on the tagger line into a
human-readable date.

This dates all the way back to a0f15fa (Pretty-print tagger
dates, 2006-03-01). At that time there was no other way to
pretty-print a tag. These days, however, neither of those
matters much. The normal way to pretty-print a tag is with
"git show", which is much more flexible than "cat-file -p".

Commit a0f15fa also built "verify-tag --verbose" (and
subsequently "tag -v") around the "cat-file -p" output.
However, that behavior was lost in commit 62e09ce (Make git
tag a builtin, 2007-07-20), and we went back to printing
the raw tag contents. Nobody seems to have noticed the bug
since then (and it is arguably a saner behavior anyway, as
it shows the actual bytes for which we verified the
signature).

Let's drop the tagger-date formatting for "cat-file -p". It
makes us more consistent with cat-file's commit
pretty-printer, and as a bonus, we can drop the hand-rolled
tag parsing code in cat-file (which happened to behave
inconsistently with the tag pretty-printing code elsewhere).

This is a change of output format, so it's possible that
some callers could considered this a regression. However,
the original behavior was arguably a bug (due to the
inconsistency with commits), likely nobody was relying on it
(even we do not use it ourselves these days), and anyone
relying on the "-p" pretty-printer should be able to expect
a change in the output format (i.e., while "cat-file" is
plumbing, the output format of "-p" was never guaranteed to
be stable).

run-command: use thread-aware die_is_recursing routineJeff King Tue, 16 Apr 2013 19:50:07 +0000 (15:50 -0400)

run-command: use thread-aware die_is_recursing routine

If we die from an async thread, we do not actually exit the
program, but just kill the thread. This confuses the static
counter in usage.c's default die_is_recursing function; it
updates the counter once for the thread death, and then when
the main program calls die() itself, it erroneously thinks
we are recursing. The end result is that we print "recursion
detected in die handler" instead of the real error in such a
case (the easiest way to trigger this is having a remote
connection hang up while running a sideband demultiplexer).

This patch solves it by using a per-thread counter when the
async_die function is installed; we detect recursion in each
thread (including the main one), but they do not step on
each other's toes.

Other threaded code does not need to worry about this, as
they do not install specialized die handlers; they just let
a die() from a sub-thread take down the whole program.

Since we are overriding the default recursion-check
function, there is an interesting corner case that is not a
problem, but bears some explanation. Imagine the main thread
calls die(), and then in the die_routine starts an async
call. We will switch to using thread-local storage, which
starts at 0, for the main thread's counter, even though
the original counter was actually at 1. That's OK, though,
for two reasons:

1. It would miss only the first level of recursion, and
would still find recursive failures inside the async
helper.

2. We do not currently and are not likely to start doing
anything as heavyweight as starting an async routine
from within a die routine or helper function.

usage: allow pluggable die-recursion checksJeff King Tue, 16 Apr 2013 19:46:22 +0000 (15:46 -0400)

usage: allow pluggable die-recursion checks

When any git code calls die or die_errno, we use a counter
to detect recursion into the die functions from any of the
helper functions. However, such a simple counter is not good
enough for threaded programs, which may call die from a
sub-thread, killing only the sub-thread (but incrementing
the counter for everyone).

Rather than try to deal with threads ourselves here, let's
just allow callers to plug in their own recursion-detection
function. This is similar to how we handle the die routine
(the caller plugs in a die routine which may kill only the
sub-thread).

read_revisions_from_stdin: make copies for handle_revision_arg

read_revisions_from_stdin() has passed pointers to its read buffer
down to handle_revision_arg() since its inception way back in 42cabc3
(Teach rev-list an option to read revs from the standard input.,
2006-09-05). Even back then, this was a bug: through
add_pending_object, the argument was recorded in the object_array's
'name' field.

Fix it by making a copy whenever read_revisions_from_stdin() passes an
argument down the callchain. The other caller runs handle_revision_arg()
on argv[], where it would be redundant to make a copy.

http: set curl FAILONERROR each time we select a handleJeff King Tue, 16 Apr 2013 00:30:38 +0000 (20:30 -0400)

http: set curl FAILONERROR each time we select a handle

Because we reuse curl handles for multiple requests, the
setup of a handle happens in two stages: stable, global
setup and per-request setup. The lifecycle of a handle is
something like:

1. get_curl_handle; do basic global setup that will last
through the whole program (e.g., setting the user
agent, ssl options, etc)

2. get_active_slot; set up a per-request baseline (e.g.,
clearing the read/write functions, making it a GET
request, etc)

3. perform the request with curl_*_perform functions

4. goto step 2 to perform another request

Breaking it down this way means we can avoid doing global
setup from step (1) repeatedly, but we still finish step (2)
with a predictable baseline setup that callers can rely on.

Until commit 6d052d7 (http: add HTTP_KEEP_ERROR option,
2013-04-05), setting curl's FAILONERROR option was a global
setup; we never changed it. However, 6d052d7 introduced an
option where some requests might turn off FAILONERROR. Later
requests using the same handle would have the option
unexpectedly turned off, which meant they would not notice
http failures at all.

This could easily be seen in the test-suite for the
"half-auth" cases of t5541 and t5551. The initial requests
turned off FAILONERROR, which meant it was erroneously off
for the rpc POST. That worked fine for a successful request,
but meant that we failed to react properly to the HTTP 401
(instead, we treated whatever the server handed us as a
successful message body).

The solution is simple: now that FAILONERROR is a
per-request setting, we move it to get_active_slot to make
sure it is reset for each request.

dir.c: git-status --ignored: don't scan the work tree... Karsten Blees Mon, 15 Apr 2013 19:15:03 +0000 (21:15 +0200)

dir.c: git-status --ignored: don't scan the work tree twice

'git-status --ignored' still scans the work tree twice to collect
untracked and ignored files, respectively.

fill_directory / read_directory already supports collecting untracked and
ignored files in a single directory scan. However, the DIR_COLLECT_IGNORED
flag to enable this has some git-add specific side-effects (e.g. it
doesn't recurse into ignored directories, so listing ignored files with
--untracked=all doesn't work).

The DIR_SHOW_IGNORED flag doesn't list untracked files and returns ignored
files in dir_struct.entries[] (instead of dir_struct.ignored[] as
DIR_COLLECT_IGNORED). DIR_SHOW_IGNORED is used all throughout git.

We don't want to break the existing API, so lets introduce a new flag
DIR_SHOW_IGNORED_TOO that lists untracked as well as ignored files similar
to DIR_COLLECT_FILES, but will recurse into sub-directories based on the
other flags as DIR_SHOW_IGNORED does.

In dir.c::read_directory_recursive, add ignored files to either
dir_struct.entries[] or dir_struct.ignored[] based on the flags. Also move
the DIR_COLLECT_IGNORED case here so that filling result lists is in a
common place.

In wt-status.c::wt_status_collect_untracked, use the new flag and read
results from dir_struct.ignored[]. Remove the extra fill_directory call.

builtin/check-ignore.c doesn't call fill_directory, setting the git-add
specific DIR_COLLECT_IGNORED flag has no effect here. Remove for clarity.

Update API documentation to reflect the changes.

Performance: with this patch, 'git-status --ignored' is typically as fast
as 'git-status'.

dir.c: git-status --ignored: don't scan the work tree three times

'git-status --ignored' recursively scans directories up to three times:

1. To collect untracked files.

2. To collect ignored files.

3. When collecting ignored files, to check that an untracked directory
that potentially contains ignored files doesn't also contain untracked
files (i.e. isn't already listed as untracked).

Let's get rid of case 3 first.

Currently, read_directory_recursive returns a boolean whether a directory
contains the requested files or not (actually, it returns the number of
files, but no caller actually needs that), and DIR_SHOW_IGNORED specifies
what we're looking for.

To be able to test for both untracked and ignored files in a single scan,
we need to return a bit more info, and the result must be independent of
the DIR_SHOW_IGNORED flag.

Reuse the path_treatment enum as return value of read_directory_recursive.
Split path_handled in two separate values path_excluded and path_untracked
that don't change their meaning with the DIR_SHOW_IGNORED flag. We don't
need an extra value path_untracked_and_excluded, as directories with both
untracked and ignored files should be listed as untracked.

Rename path_ignored to path_none for clarity (i.e. "don't treat that path"
in contrast to "the path is ignored and should be treated according to
DIR_SHOW_IGNORED").

Replace enum directory_treatment with path_treatment. That's just another
enum with the same meaning, no need to translate back and forth.

In treat_directory, get rid of the extra read_directory_recursive call and
all the DIR_SHOW_IGNORED-specific code.

In read_directory_recursive, decide whether to dir_add_name path_excluded
or path_untracked paths based on the DIR_SHOW_IGNORED flag.

The return value of read_directory_recursive is the maximum path_treatment
of all files and sub-directories. In the check_only case, abort when we've
reached the most significant value (path_untracked).

dir.c: git-status: avoid is_excluded checks for tracked files

Checking if a file is in the index is much faster (hashtable lookup) than
checking if the file is excluded (linear search over exclude patterns).

Skip is_excluded checks for files: move the cache_name_exists check from
treat_file to treat_one_path and return early if the file is tracked.

This can safely be done as all other code paths also return path_ignored
for tracked files, and dir_add_ignored skips tracked files as well.

There's just one line left in treat_file, so move this to treat_one_path
as well.

dir.c: unify is_excluded and is_path_excluded APIs

The is_excluded and is_path_excluded APIs are very similar, except for a
few noteworthy differences:

is_excluded doesn't handle ignored directories, results for paths within
ignored directories are incorrect. This is probably based on the premise
that recursive directory scans should stop at ignored directories, which
is no longer true (in certain cases, read_directory_recursive currently
calls is_excluded *and* is_path_excluded to get correct ignored state).

is_excluded caches parsed .gitignore files of the last directory in struct
dir_struct. If the directory changes, it finds a common parent directory
and is very careful to drop only as much state as necessary. On the other
hand, is_excluded will also read and parse .gitignore files in already
ignored directories, which are completely irrelevant.

is_path_excluded correctly handles ignored directories by checking if any
component in the path is excluded. As it uses is_excluded internally, this
unfortunately forces is_excluded to drop and re-read all .gitignore files,
as there is no common parent directory for the root dir.

is_path_excluded tracks state in a separate struct path_exclude_check,
which is essentially a wrapper of dir_struct with two more fields. However,
as is_path_excluded also modifies dir_struct, it is not possible to e.g.
use multiple path_exclude_check structures with the same dir_struct in
parallel. The additional structure just unnecessarily complicates the API.

Teach is_excluded / prep_exclude about ignored directories: whenever
entering a new directory, first check if the entire directory is excluded.
Remember the excluded state in dir_struct. Don't traverse into already
ignored directories (i.e. don't read irrelevant .gitignore files).

Directories could also be excluded by exclude patterns specified on the
command line or .git/info/exclude, so we cannot simply skip prep_exclude
entirely if there's no .gitignore file name (dir_struct.exclude_per_dir).
Move this check to just before actually reading the file.

is_path_excluded is now equivalent to is_excluded, so we can simply
redirect to it (the public API is cleaned up in the next patch).

The performance impact of the additional ignored check per directory is
hardly noticeable when reading directories recursively (e.g. 'git status').
However, performance of git commands using the is_path_excluded API (e.g.
'git ls-files --cached --ignored --exclude-standard') is greatly improved
as this no longer re-reads .gitignore files on each call.

Here's some performance data from the linux and WebKit repos (best of 10
runs on a Debian Linux on SSD, core.preloadIndex=true):

dir.c: git-clean -d -X: don't delete tracked directories

The notion of "ignored tracked" directories introduced in 721ac4ed "dir.c:
Make git-status --ignored more consistent" has a few unwanted side effects:

- git-clean -d -X: deletes ignored tracked directories. git-clean should
never delete tracked content.

- git-ls-files --ignored --other --directory: lists ignored tracked
directories instead of "other" directories.

- git-status --ignored: lists ignored tracked directories while contained
files may be listed as modified. Paths listed by git-status should be
disjoint (except in long format where a path may be listed in both the
staged and unstaged section).

Additionally, the current behaviour violates documentation in gitignore(5)
("Specifies intentionally *untracked* files to ignore") and Documentation/
technical/api-directory-listing.txt ("DIR_SHOW_OTHER_DIRECTORIES: Include
a directory that is *not tracked*.").

In dir.c::treat_directory, remove the special handling of ignored tracked
directories, so that the DIR_SHOW_OTHER_DIRECTORIES flag only affects
"other" (i.e. untracked) directories. In dir.c::dir_add_name, check that
added paths are untracked even if DIR_SHOW_IGNORED is set.

When bisect successfully finds a single revision, the first bad commit
should be shown to human readers of 'git bisect log'.

transport-helper: pass --signed-tags=warn-strip to fast-export

Currently, attempting to push a signed tag to a remote helper which uses
fast-export results in the remote helper failing because the default
fast-export action for signed tags is "abort". This is not helpful for
users because there is no way to pass additional arguments to
fast-export here, either from the remote helper or from the command
line.

In general, the signature will be invalidated by whatever transformation
a remote helper performs on a tag to push it to a repository in a
different format so the correct behaviour is to strip the tag. Doing
this silently may surprise people, so use "warn-strip" to issue a
warning when a signed tag is encountered.

with another meaning: to add back all files in <paths> that are

The $test variable is used as an interim buffer for

later code does not accidentally use it, thinking the two

t/test-lib.sh: fix TRASH_DIRECTORY handling

After the location of $TRASH_DIRECTORY is adjusted by
$TEST_OUTPUT_DIRECTORY, we go on to use the $test variable to make the
trash directory and cd into it. This means that when
$TEST_OUTPUT_DIRECTORY is not "." and an absolute --root has not been
specified, we do not remove the trash directory once the tests are
complete (remove_trash is set to $TRASH_DIRECTORY).

Fix this by always referring to the trash directory as $TRASH_DIRECTORY.

completion: inline __gitcomp_1 to its sole callsite

There is no point in calling a separate function that is only used
in one place. Especially considering that there's no need to call
compgen, and we traverse the words ourselves both in __gitcompadd,
and __gitcomp_1.

Let's squash the functions together, and traverse only once.

This improves performance. For N number of words:

new: 0.000s
== 10 ==

completion: get rid of compgen

The functionality we use from compgen is not much, we can do the same
manually, with drastic improvements in speed, especially when dealing
with only a few words.

This patch also has the sideffect that brekage reported by Jeroen Meijer
and SZEDER Gábor gets fixed because we no longer expand the resulting
words.

Here are some numbers filtering N amount of words:

== 1 ==
original: 0.002s
new: 0.000s
== 10 ==
original: 0.002s
new: 0.000s
== 100 ==
original: 0.003s
new: 0.002s
== 1000 ==
original: 0.012s
new: 0.011s
== 10000 ==
original: 0.056s
new: 0.066s
== 100000 ==
original: 2.669s
new: 0.622s

If the results are not narrowed:

== 1 ==
original: 0.002s
new: 0.000s
== 10 ==
original: 0.002s
new: 0.001s
== 100 ==
original: 0.004s
new: 0.004s
== 1000 ==
original: 0.020s
new: 0.015s
== 10000 ==
original: 0.101s
new: 0.355s
== 100000 ==
original: 2.850s
new: 31.941s

So, unless 'git checkout <tab>' usually gives you more than 10000
results, you'll get an improvement :)

Other possible solutions perform better after 1000 words, but worst if
less than that:

COMPREPLY=($(awk -v cur="$3" -v pre="$2" -v suf="$4"
'$0 ~ cur { print pre$0suf }' <<< "$1" ))

COMPREPLY=($(printf -- "$2%s$4\n" $1 | grep "^$2$3"))

The idea is to never touch the COMPREPLY variable directly.

This allows other completion systems (i.e. zsh) to override
__gitcompadd, and do something different instead.

Also, this allows further optimizations down the line.

doc/http-backend: match query-string in apache half... Jeff King Sat, 13 Apr 2013 03:33:36 +0000 (23:33 -0400)

doc/http-backend: match query-string in apache half-auth example

When setting up a "half-auth" repository in which reads can
be done anonymously but writes require authentication, it is
best if the server can require authentication for both the
ref advertisement and the actual receive-pack POSTs. This
alleviates the need for the admin to set http.receivepack in
the repositories, and means that the client is challenged
for credentials immediately, instead of partway through the
push process (and git clients older than v1.7.11.7 had
trouble handling these challenges).

Since detecting a push during the ref advertisement requires
matching the query string, and this is non-trivial to do in
Apache, we have traditionally punted and instructed users to
just protect "/git-receive-pack$". This patch provides the
mod_rewrite recipe to actually match the ref advertisement,
which is preferred.

While we're at it, let's add the recipe to our test scripts
so that we can be sure that it works, and doesn't get broken
(either by our changes or by changes in Apache).

- Use printf instead of echo -e

Use UTF-8 code points which are not decomposed by the filesystem:
Code points like "á" will be decomposed by Mac OS X.
bzr is unable to find the file "á" on disk.
Use code points from unicode which can not be decomposed.
In other words, the precompsed form use the same bytes as decomposed.
