Makefile: Change the default compiler from "gcc" to "cc"

Ever since the very first commit to git.git we've been setting CC to
"gcc". Presumably this is behavior that Linus copied from the Linux
Makefile.

However unlike Linux Git is written in ANSI C and supports a multitude
of compilers, including Clang, Sun Studio, xlc etc. On my Linux box
"cc" is a symlink to clang, and on a Solaris box I have access to "cc"
is Sun Studio's CC.

Both of these are perfectly capable of compiling Git, and it's
annoying to have to specify CC=cc on the command-line when compiling
Git when that's the default behavior of most other portable programs.

So change the default to "cc". Users who want to compile with GCC can
still add "CC=gcc" to the make(1) command-line, but those users who
don't have GCC as their "cc" will see expected behavior, and as a
bonus we'll be more likely to smoke out new compilation warnings from
our distributors since they'll me using a more varied set of compilers
by default.

add -e: do not show difference in a submodule that is merely dirty

When the HEAD of the submodule matches what is recorded in the index of
the superproject, and it has local changes or untracked files, the patch
offered by "git add -e" for editing shows a diff like this:

diff --git a/submodule b/submodule
<header>
-deadbeef...
+deadbeef...-dirty

Because applying such a patch has no effect to the index, this is a
useless noise. Generate the patch with IGNORE_DIRTY_SUBMODULES flag to
prevent such a change from getting reported.

This patch also loses the "-dirty" suffix from the output when the HEAD of
the submodule is different from what is in the index of the superproject.
As such dirtiness expressed by the suffix does not affect the result of
the patch application at all, there is no information lost if we remove
it. The user could still run "git status" before "git add -e" if s/he
cares about the dirtiness.

branch --edit-description: protect against mistyped branch name

It is very easy to mistype the branch name when editing its description,
e.g.

$ git checkout -b my-topic master
: work work work
: now we are at a good point to switch working something else
$ git checkout master
: ah, let's write it down before we forget what we were doing
$ git branch --edit-description my-tpoic

The command does not notice that branch 'my-tpoic' does not exist. It is
not lost (it becomes description of an unborn my-tpoic branch), but is not
very useful. So detect such a case and error out to reduce the grief
factor from this common mistake.

This incidentally also errors out --edit-description when the HEAD points
at an unborn branch (immediately after "init", or "checkout --orphan"),
because at that point, you do not even have any commit that is part of
your history and there is no point in describing how this particular
branch is different from the branch it forked off of, which is the useful
bit of information the branch description is designed to capture.

We may want to special case the unborn case later, but that is outside the
scope of this patch to prevent more common mistakes before 1.7.9 series
gains too much widespread use.

merge: do not create a signed tag merge under --ff-only option

Starting at release v1.7.9, if you ask to merge a signed tag, "git merge"
always creates a merge commit, even when the tag points at a commit that
happens to be a descendant of your current commit.

Unfortunately, this interacts rather badly for people who use --ff-only to
make sure that their branch is free of local developments. It used to be
possible to say:

$ git checkout -b frotz v1.7.9~30
$ git merge --ff-only v1.7.9

and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka
the commit tagged as v1.7.9), but this fails with the updated Git with:

fatal: Not possible to fast-forward, aborting.

because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by
fast forwarding.

We could teach users that now they have to do

$ git merge --ff-only v1.7.9^0

but it is far more pleasant for users if we DWIMmed this ourselves.

When an integrator pulls in a topic from a lieutenant via a signed tag,
even when the work done by the lieutenant happens to fast-forward, the
integrator wants to have a merge record, so the integrator will not be
asking for --ff-only when running "git pull" in such a case. Therefore,
this change should not regress the support for the use case v1.7.9 wanted
to add.

parse_date(): '@' prefix forces git-timestampJunio C Hamano Thu, 2 Feb 2012 21:41:43 +0000 (13:41 -0800)

parse_date(): '@' prefix forces git-timestamp

The only place that the issue this series addresses was observed
where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE
in order to replay a commit with an ancient timestamp.

With the previous patch alone, "git commit --date='20100917 +0900'"
can be misinterpreted to mean an ancient timestamp, not September in
year 2010. Guard this codepath by requring an extra '@' in front of
the raw git timestamp on the parsing side. This of course needs to
be compensated by updating get_author_ident_from_commit and the code
for "git commit --amend" to prepend '@' to the string read from the
existing commit in the GIT_AUTHOR_DATE environment variable.

parse_date(): allow ancient git-timestampJunio C Hamano Thu, 2 Feb 2012 21:41:42 +0000 (13:41 -0800)

parse_date(): allow ancient git-timestamp

The date-time parser parses out a human-readble datestring piece by
piece, so that it could even parse a string in a rather strange
notation like 'noon november 11, 2005', but restricts itself from
parsing strings in "<seconds since epoch> <timezone>" format only
for reasonably new timestamps (like 1974 or newer) with 10 or more
digits. This is to prevent a string like "20100917" from getting
interpreted as seconds since epoch (we want to treat it as September
17, 2010 instead) while doing so.

The same codepath is used to read back the timestamp that we have
already recorded in the headers of commit and tag objects; because
of this, such a commit with timestamp "0 +0000" cannot be rebased or
amended very easily.

Teach parse_date() codepath to special case a string of the form
"<digits> +<4-digits>" to work this issue around, but require that
there is no other cruft around the string when parsing a timestamp
of this format for safety.

Note that this has a slight backward incompatibility implications.

If somebody writes "git commit --date='20100917 +0900'" and wants it
to mean a timestamp in September 2010 in Japan, this change will
break such a use case.

tests: add write_script helper functionJunio C Hamano Sat, 4 Feb 2012 06:29:01 +0000 (01:29 -0500)

tests: add write_script helper function

Many of the scripts in the test suite write small helper
shell scripts to disk. It's best if these shell scripts
start with "#!$SHELL_PATH" rather than "#!/bin/sh", because
/bin/sh on some platforms is too buggy to be used.

However, it can be cumbersome to expand $SHELL_PATH, because
the usual recipe for writing a script is:

cat >foo.sh <<-\EOF
#!/bin/sh
echo my arguments are "$@"
EOF

To expand $SHELL_PATH, you have to either interpolate the
here-doc (which would require quoting "\$@"), or split the
creation into two commands (interpolating the $SHELL_PATH
line, but not the rest of the script). Let's provide a
helper function that makes that less syntactically painful.

While we're at it, this helper can also take care of the
"chmod +x" that typically comes after the creation of such a
script, saving the caller a line.

request-pull: explicitly ask tags/$name to be pulled

When asking for a tag to be pulled, disambiguate by leaving tags/ prefix
in front of the name of the tag. E.g.

... in the git repository at:

git://example.com/git/git.git/ tags/v1.2.3

for you to fetch changes up to 123456...

This way, older versions of "git pull" can be used to respond to such a
request more easily, as "git pull $URL v1.2.3" did not DWIM to fetch
v1.2.3 tag in older versions. Also this makes it clearer for humans that
the pull request is made for a tag and he should anticipate a signed one.

git-completion: workaround zsh COMPREPLY bug

zsh adds a backslash (foo\ ) for each item in the COMPREPLY array if IFS
doesn't contain spaces. This issue has been reported[1], but there is no
solution yet.

This wasn't a problem due to another bug[2], which was fixed in zsh
version 4.3.12. After this change, 'git checkout ma<tab>' would resolve
to 'git checkout master\ '.

Aditionally, the introduction of __gitcomp_nl in commit a31e626
(completion: optimize refs completion) in git also made the problem
apparent, as Matthieu Moy reported.

The simplest and most generic solution is to hide all the changes we do
to IFS, so that "foo \nbar " is recognized by zsh as "foo bar". This
works on versions of git before and after the introduction of
__gitcomp_nl (a31e626), and versions of zsh before and after 4.3.12.

Once zsh is fixed, we should conditionally disable this workaround to
have the same benefits as bash users.

submodule add: fix breakage when re-adding a deep submodule

Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there.

When the same submodule is added on a branch where it wasn't present so
far (it is not found in the .gitmodules file), the name is not initialized
from the path as it should. This leads to a wrong path entered in the
gitfile when the .git/modules/<name> directory is found, as this happily
uses the - now empty - name. It then always points only a single directory
up, even if we have a path deeper in the directory hierarchy.

Fix that by initializing the name of the submodule early in module_clone()
if module_name() returned an empty name and add a test to catch that bug.

In threaded mode, git-grep emits file breaks (enabled with context, -W

required. The output collection thread then uses skip_first_line to
skip the first such line in the output, which would otherwise be at

This is wrong when the user also specified -l/-L/-c, in which case
every line is relevant. While arguably giving these options together
doesn't make any sense, git-grep has always quietly accepted it. So

remote-curl: Fix push status report when all branches... Shawn O. Pearce Fri, 20 Jan 2012 03:12:09 +0000 (19:12 -0800)

remote-curl: Fix push status report when all branches fail

The protocol between transport-helper.c and remote-curl requires
remote-curl to always print a blank line after the push command
has run. If the blank line is ommitted, transport-helper kills its
container process (the git push the user started) with exit(128)
and no message indicating a problem, assuming the helper already
printed reasonable error text to the console.

However if the remote rejects all branches with "ng" commands in the
report-status reply, send-pack terminates with non-zero status, and
in turn remote-curl exited with non-zero status before outputting
the blank line after the helper status printed by send-pack. No
error messages reach the user.

This caused users to see the following from git push over HTTP
when the remote side's update hook rejected the branch:

$ git push http://... master
Counting objects: 4, done.
Delta compression using up to 6 threads.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 301 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)
$

Always print a blank line after the send-pack process terminates,
ensuring the helper status report (if it was output) will be
correctly parsed by the calling transport-helper.c. This ensures
the helper doesn't abort before the status report can be shown to
the user.

Making pathspec limited log play nicer with --first... Junio C Hamano Thu, 19 Jan 2012 19:58:45 +0000 (11:58 -0800)

Making pathspec limited log play nicer with --first-parent

In a topic branch workflow, you often want to find the latest commit that
merged a side branch that touched a particular area of the system, so that
a new topic branch to work on that area can be forked from that commit.
For example, I wanted to find an appropriate fork-point to queue Luke's
changes related to git-p4 in contrib/fast-import/.

"git log --first-parent" traverses the first-parent chain, and "-m --stat"
shows the list of paths touched by commits including merge commits. We
could ask the question this way:

# What is the latest commit that touched that path?
$ git log --first-parent --oneline -m --stat master |
sed -e '/^ contrib\/fast-import\/git-p4 /q' | tail

The above finds that 8cbfc11 (Merge branch 'pw/p4-view-updates',
2012-01-06) was such a commit.

But a more natural way to spell this question is this:

$ git log --first-parent --oneline -m --stat -1 master -- \
contrib/fast-import/git-p4

Unfortunately, this does not work. It finds ecb7cf9 (git-p4: rewrite view
handling, 2012-01-02). This commit is a part of the merged topic branch
and is _not_ on the first-parent path from the 'master':

$ git show-branch 8cbfc11 ecb7cf9
! [8cbfc11] Merge branch 'pw/p4-view-updates'
! [ecb7cf9] git-p4: rewrite view handling
--
- [8cbfc11] Merge branch 'pw/p4-view-updates'
+ [8cbfc11^2] git-p4: view spec documentation
++ [ecb7cf9] git-p4: rewrite view handling

The problem is caused by the merge simplification logic when it inspects
the merge commit 8cbfc11. In this case, the history leading to the tip of
'master' did not touch git-p4 since 'pw/p4-view-updates' topic forked, and
the result of the merge is simply a copy from the tip of the topic branch
in the view limited by the given pathspec. The merge simplification logic
discards the history on the mainline side of the merge, and pretends as if
the sole parent of the merge is its second parent, i.e. the tip of the
topic. While this simplification is correct in the general case, it is at
least surprising if not outright wrong when the user explicitly asked to
show the first-parent history.

Here is an attempt to fix this issue, by not allowing us to compare the
merge result with anything but the first parent when --first-parent is in
effect, to avoid the history traversal veering off to the side branch.

diff-index: enable recursive pathspec matching in unpack_trees

The pathspec structure has a few bits of data to drive various operation
modes after we unified the pathspec matching logic in various codepaths.
For example, max_depth field is there so that "git grep" can limit the
output for files found in limited depth of tree traversal. Also in order
to show just the surface level differences in "git diff-tree", recursive
field stops us from descending into deeper level of the tree structure
when it is set to false, and this also affects pathspec matching when
we have wildcards in the pathspec.

The diff-index has always wanted the recursive behaviour, and wanted to
match pathspecs without any depth limit. But we forgot to do so when we
updated tree_entry_interesting() logic to unify the pathspec matching
logic.

credential-cache: ignore "connection refused" errors

The credential-cache helper will try to connect to its
daemon over a unix socket. Originally, a failure to do so
was silently ignored, and we would either give up (if
performing a "get" or "erase" operation), or spawn a new
daemon (for a "store" operation).

But since 8ec6c8d, we try to report more errors. We detect a
missing daemon by checking for ENOENT on our connection
attempt. If the daemon is missing, we continue as before
(giving up or spawning a new daemon). For any other error,
we die and report the problem.

However, checking for ENOENT is not sufficient for a missing
daemon. We might also get ECONNREFUSED if a dead daemon
process left a stale socket. This generally shouldn't
happen, as the daemon cleans up after itself, but the daemon
may not always be given a chance to do so (e.g., power loss,
"kill -9").

The resulting state is annoying not just because the helper
outputs an extra useless message, but because it actually
blocks the helper from spawning a new daemon to replace the
stale socket.

Fix it by checking for ECONNREFUSED.

Two "^" characters were incorrectly being interpreted as markup for
superscripting. Fix them by writing them as attribute references
"{caret}".

Although a single "^" character in a paragraph cannot be
misinterpreted in this way, also write other "^" characters as
"{caret}" in the interest of good hygiene (unless they are in literal
paragraphs, of course, in which context attribute references are not
recognized).

Spell "{}" consistently, namely *not* quoted as "\{\}". Since the
braces are empty, they cannot be interpreted as an attribute
reference, and either spelling is OK. So arbitrarily choose one
variation and use it consistently.

thin-pack: try harder to use preferred base objects... Jeff King Thu, 12 Jan 2012 22:32:34 +0000 (17:32 -0500)

thin-pack: try harder to use preferred base objects as base

When creating a pack using objects that reside in existing packs, we try
to avoid recomputing futile delta between an object (trg) and a candidate
for its base object (src) if they are stored in the same packfile, and trg
is not recorded as a delta already. This heuristics makes sense because it
is likely that we tried to express trg as a delta based on src but it did
not produce a good delta when we created the existing pack.

As the pack heuristics prefer producing delta to remove data, and Linus's
law dictates that the size of a file grows over time, we tend to record
the newest version of the file as inflated, and older ones as delta
against it.

When creating a thin-pack to transfer recent history, it is likely that we
will try to send an object that is recorded in full, as it is newer. But
the heuristics to avoid recomputing futile delta effectively forbids us
from attempting to express such an object as a delta based on another
object. Sending an object in full is often more expensive than sending a
suboptimal delta based on other objects, and it is even more so if we
could use an object we know the receiving end already has (i.e. preferred
base object) as the delta base.

Tweak the recomputation avoidance logic, so that we do not punt on
computing delta against a preferred base object.

The effect of this change can be seen on two simulated upload-pack
workloads. The first is based on 44 reflog entries from my git.git
origin/master reflog, and represents the packs that kernel.org sent me git
updates for the past month or two. The second workload represents much
larger fetches, going from git's v1.0.0 tag to v1.1.0, then v1.1.0 to
v1.2.0, and so on.

The table below shows the average generated pack size and the average CPU
time consumed for each dataset, both before and after the patch:

dataset
| reflog | tags
---------------------------------
before | 53358 | 2750977
size after | 32398 | 2668479
change | -39% | -3%
---------------------------------
before | 0.18 | 1.12
CPU after | 0.18 | 1.15
change | +0% | +3%

This patch makes a much bigger difference for packs with a shorter slice
of history (since its effect is seen at the boundaries of the pack) though
it has some benefit even for larger packs.

word-diff: ignore '\ No newline at eof' marker

The word-diff logic accumulates + and - lines until another line type
appears (normally [ @\]), at which point it generates the word diff.
This is usually correct, but it breaks when the preimage does not have
a newline at EOF:

$ printf "%s" "a a a" >a
$ printf "%s\n" "a ab a" >b
$ git diff --no-index --word-diff a b
diff --git 1/a 2/b

[-a a a-]
No newline at end of file

Because of the order of the lines in a unified diff

@@ -1 +1 @@
-a a a
\ No newline at end of file
+a ab a

the '\' line flushed the buffers, and the - and + lines were never
matched with each other.

A proper fix would defer such markers until the end of the hunk.
However, word-diff is inherently whitespace-ignoring, so as a cheap
fix simply ignore the marker (and hide it from the output).

We use a prefix match for '\ ' to parallel the logic in
apply.c:parse_fragment(). We currently do not localize this string
(just accept other variants of it in git-apply), but this should be
future-proof.

unix-socket: do not let close() or chdir() clobber errno during cleanup

unix_stream_connect and unix_stream_listen return -1 on error, with
errno set by the failing underlying call to allow the caller to write
a useful diagnosis.

Unfortunately the error path involves a few system calls itself, such
as close(), that can themselves touch errno.

This is not as worrisome as it might sound. If close() fails, this
just means substituting one meaningful error message for another,
which is perfectly fine. However, when the call _succeeds_, it is
allowed to (and sometimes might) clobber errno along the way with some
undefined value, so it is good higiene to save errno and restore it
immediately before returning to the caller. Do so.

enumeration of all the transformations. Specifically, it was missing
the whitespace normalization (run of isspace(c) -> ' ') and the
removal of leading ':'.

t2203: fix wrong commit command

Add commit message to avoid commit's aborting due to the lack of
commit message, not because there are INTENT_TO_ADD entries in index.

request-pull: use the real fork point when preparing the message

The command takes the "start" argument and computes the merge base
between it and the commit to be pulled so that we can show the diffstat,
but uses the "start" argument as-is when composing the message

The following changes since commit $X are available

to tell the integrator which commit the work is based on. Giving "origin"
(most of the time it resolves to refs/remotes/origin/master) as the start
argument is often convenient, but it is usually not the fork point, and
does not help the integrator at all.

Use the real fork point, which is the merge base we already compute, when
composing that part of the message.

attr: drop misguided defensive coding

In prepare_attr_stack, we pop the old elements of the stack
(which were left from a previous lookup and may or may not
be useful to us). Our loop to do so checks that we never
reach the top of the stack. However, the code immediately
afterwards will segfault if we did actually reach the top of
the stack.

Fortunately, this is not an actual bug, since we will never
pop all of the stack elements (we will always keep the root
gitattributes, as well as the builtin ones). So the extra
check in the loop condition simply clutters the code and
makes the intent less clear. Let's get rid of it.
