repack: place temporary packs under .git/objects/pack/

git-pack-objects is already careful to start out its temporary packs
under .git/objects/pack/ (cf. 8b4eb6b, Do not perform cross-directory
renames when creating packs, 2008-09-22), but git-repack did not
respond in kind so the effort was lost when the filesystem boundary is
exactly at that directory.

Let git-repack pass a path under .git/objects/pack/ as the base for
its temporary packs.

This means we might need the $PACKDIR sooner (before the pack-objects
invocation), so move the mkdir up just to be safe.

Also note that the only use of *.pack is in the find invocation way
before the pack-objects call, so the temporary packs will not suddenly
show up in any wildcards because of the directory change.

fast-import: tighten M 040000 syntaxJonathan Nieder Mon, 18 Oct 2010 01:08:53 +0000 (20:08 -0500)

fast-import: tighten M 040000 syntax

When tree_content_set() is asked to modify the path "foo/bar/",
it first recurses like so:

tree_content_set(root, "foo/bar/", sha1, S_IFDIR) ->
tree_content_set(root:foo, "bar/", ...) ->
tree_content_set(root:foo/bar, "", ...)

And as a side-effect of 2794ad5 (fast-import: Allow filemodify to set
the root, 2010-10-10), this last call is accepted and changes
the tree entry for root:foo/bar to refer to the specified tree.

That seems safe enough but let's reject the new syntax (we never meant
to support it) and make it harder for frontends to introduce pointless
incompatibilities with git fast-import 1.7.3.

push: pass --progress down to git-pack-objects

When pushing via builtin transports (like file://, git://), the

Fix this, and update the tests to reflect this.

Note that according to the git-pack-objects documentation, we can safely
apply the usual --progress semantics for the transport commands like
clone and fetch (and for pushing over other smart transports).

test_terminal: ensure redirections work reliablyJonathan Nieder Sun, 17 Oct 2010 00:38:07 +0000 (19:38 -0500)

test_terminal: ensure redirections work reliably

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).

$ test_terminal.perl sh -c 'test -t 1 && echo >&2 YES' >out
YES
$ sh -c 'test -t 1 && echo >&2 YES' >out
$

So:

- 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
than being swallowed up by an unrelated redireciton.

test_terminal: catch use without TTY prerequisite

It is easy to forget to declare the TTY prerequisite when
writing tests on a system where it would always be satisfied
(because IO::Pty is installed; see v1.7.3-rc0~33^2, 2010-08-16

test_terminal: need to declare TTY prerequisite

test_terminal returns status 127 in this case to simulate
not being available.

Also replace the SIMPLEPAGERTTY prerequisite on one test with
"SIMPLEPAGER,TTY", since (1) the latter is supported now and
(2) the prerequisite detection relies on the TTY prereq being

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

Saying "pack-objects died with strange error" after "pack-objects died
of signal 13" seems kind of redundant. The latter message was
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
error: pack-objects died of signal 13
error: failed to push some refs to 'ssh://sf.net/gitroot/project/project'
$

Or in the "controlled exit" case (contrived example):

[...]
fatal: delta size changed
error: failed to push some refs to 'ssh://example.com/foo/bar'
$

mailmap: fix use of freed memory

On an x86_64 system (F13-based), I ran these commands in an empty directory:

git init
printf '%s\n' \
'<jdoe@example.com> <jdoe@example.COM>' \
'John <jdoe@example.com>' > .mailmap
git shortlog < /dev/null

Here's the result:

(reading log message from standard input)
*** glibc detected *** git: free(): invalid pointer: 0x0000000000f53730 ***
======= Backtrace: =========

git[0x4b9858]
...
zsh: abort (core dumped) git shortlog

What happened?

Some .mailmap entry is of the <email1> <email2> form,
while a subsequent one looks like "User Name <Email2>,
and the two email addresses on the right are not identical
but are "equal" when using a case-insensitive comparator.

Then, when add_mapping is processing the latter line, new_email is NULL
and we free me->email, yet do not replace it with a new strdup'd string.
Thus, when later we attempt to use the buffer behind that ->email pointer,
we reference freed memory.

The solution is to free ->email and ->name only if we're about to replace them.

fast-import: Allow filemodify to set the root

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,

M 040000 4b825dc642cb6eb9a060e54bf8d69288fbee4904 ""

is a synonym for the deleteall command and the fast-import equivalent of

git read-tree 4b825dc642cb6eb9a060e54bf8d69288fbee4904

bash: support pretty format aliasesSZEDER Gábor Sun, 10 Oct 2010 22:06:22 +0000 (00:06 +0200)

bash: support pretty format aliases

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'SZEDER Gábor Sun, 10 Oct 2010 21:48:58 +0000 (23:48 +0200)

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

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.

Also make sure that a merge which fails due to

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

major restructuring. See the following thread for

gitweb: Improve behavior for actionless path_info gitweb URLs

Eli Barzilay noticed that

http://server/gitweb/project/<commit-sha1>

link goes to 'shortlog' view, while 'commit' view would be more
useful, but that 'shortlog' action is more apropriate for

http://server/gitweb/project/<commit-sha1>..<other-commit-sha1>

links.

Therefore for the case when we don't have either action, or filename,
or parent hash [base] in path_info-based URL, i.e. for

http://server/gitweb/project/<object-id>

link, instead of using 'shortlog' view we allow dispatch() subroutine
to detect type of object and use appropriate action (in most case it
would be either 'commit' action, or 'tag', or 'tree' for top
directory).

test-lib: make test_expect_code a test command

Change test_expect_code to be a normal test command instead of a
top-level command.

As a top-level command it would fail in cases like:

test_expect_code 1 'phoney' '
foo && bar && (exit 1)
'

Here the test might incorrectly succeed if "foo" or "bar" happened to
fail with exit status 1. Instead we now do:

test_expect_success 'phoney' '
foo && bar && test_expect_code 1 "(exit 1)"
'

Which will only succeed if "foo" and "bar" return status 0, and "(exit
1)" returns status 1. Note that test_expect_code has been made slightly
noisier, as it reports the exit code it receives even upon success.

Some test code in t0000-basic.sh relied on the old semantics of
test_expect_code to test the test_when_finished command. I've
converted that code to use an external test similar to the TODO test I
added in v1.7.3-rc0~2^2~3.

Support case folding for git add when core.ignorecase... Joshua Jensen Sun, 3 Oct 2010 09:56:45 +0000 (09:56 +0000)

Support case folding for git add when core.ignorecase=true

When MyDir/ABC/filea.txt is added to Git, the disk directory MyDir/ABC/
is renamed to mydir/aBc/, and then mydir/aBc/fileb.txt is added, the
index will contain MyDir/ABC/filea.txt and mydir/aBc/fileb.txt. Although
the earlier portions of this patch series account for those differences
in case, this patch makes the pathing consistent by folding the case of
newly added files against the first file added with that path.

In read-cache.c's add_to_index(), the index_name_exists() support used
for git status's case insensitive directory lookups is used to find the
proper directory case according to what the user already checked in.
That is, MyDir/ABC/'s case is used to alter the stored path for
fileb.txt to MyDir/ABC/fileb.txt (instead of mydir/aBc/fileb.txt).

This is especially important when cloning a repository to a case
sensitive file system. MyDir/ABC/ and mydir/aBc/ exist in the same
directory on a Windows machine, but on Linux, the files exist in two
separate directories. The update to add_to_index(), in effect, treats a
Windows file system as case sensitive by making path case consistent.

Add case insensitivity support when using git ls-filesJoshua Jensen Sun, 3 Oct 2010 09:56:44 +0000 (09:56 +0000)

Add case insensitivity support when using git ls-files

When mydir/filea.txt is added, mydir/ is renamed to MyDir/, and
MyDir/fileb.txt is added, running git ls-files mydir only shows
mydir/filea.txt. Running git ls-files MyDir shows MyDir/fileb.txt.
Running git ls-files mYdIR shows nothing.

With this patch running git ls-files for mydir, MyDir, and mYdIR shows
mydir/filea.txt and MyDir/fileb.txt.

Wildcards are not handled case insensitively in this patch. Example:
MyDir/aBc/file.txt is added. git ls-files MyDir/a* works fine, but git
ls-files mydir/a* does not.

Add case insensitivity support for directories when... Joshua Jensen Sun, 3 Oct 2010 09:56:43 +0000 (09:56 +0000)

Add case insensitivity support for directories when using git status

When using a case preserving but case insensitive file system, directory
case can differ but still refer to the same physical directory. git
status reports the directory with the alternate case as an Untracked
file. (That is, when mydir/filea.txt is added to the repository and
then the directory on disk is renamed from mydir/ to MyDir/, git status
shows MyDir/ as being untracked.)

Support has been added in name-hash.c for hashing directories with a
terminating slash into the name hash. When index_name_exists() is called
with a directory (a name with a terminating slash), the name is not
found via the normal cache_name_compare() call, but it is found in the
slow_same_name() function.

Additionally, in dir.c, directory_exists_in_index_icase() allows newly
added directories deeper in the directory chain to be identified.

Ultimately, it would be better if the file list was read in case
insensitive alphabetical order from disk, but this change seems to
suffice for now.

The end result is the directory is looked up in a case insensitive
manner and does not show in the Untracked files list.

Case insensitivity support for .gitignore via core... Joshua Jensen Sun, 3 Oct 2010 09:56:42 +0000 (09:56 +0000)

Case insensitivity support for .gitignore via core.ignorecase

This is especially beneficial when using Windows and Perforce and the
git-p4 bridge. Internally, Perforce preserves a given file's full path
including its case at the time it was added to the Perforce repository.
When syncing a file down via Perforce, missing directories are created,
if necessary, using the case as stored with the filename. Unfortunately,
two files in the same directory can have differing cases for their
respective paths, such as /diRa/file1.c and /DirA/file2.c. Depending on
sync order, DirA/ may get created instead of diRa/.

It is possible to handle directory names in a case insensitive manner
without this patch, but it is highly inconvenient, requiring each
character to be specified like so: [Bb][Uu][Ii][Ll][Dd]. With this patch, the
gitignore exclusions honor the core.ignorecase=true configuration
setting and make the process less error prone. The above is specified
like so: Build
