The first "grep -C1" test in t7002 does not pass on my SunOS-5.11-i86pc,
and that is not because our way to spawn external grep is broken, but
because the native grep does not understand -C<n>.
It turns out that Peff was also using this option himself because our
Makefile doesn't do that automatically. Brandon Casey uses SUNWspro
compiler without having to set this, and it turns out that the compiler
does not define preprocessor macro __unix__ which made him always use the
built-in grep, never an external one.
Let's be more explicit and say that we do not use external grep on Suns.

When you have grafts that pretend that a given commit has different
parents than the ones recorded in the commit object, it is dangerous
to let 'git repack' remove those hidden parents, as you can easily
remove the graft and end up with a broken repository.
So let's play it safe and keep those parent objects and everything
that is reachable by them, in addition to the grafted parents.
As this behavior can only be triggered by git pack-objects, and as that
command handles duplicate parents gracefully, we do not bother to cull
duplicated parents that may result by using both true and grafted
parents.

'git branch' looks at _all_ the refs, and verifies them. Which means that
during cold-cache situations with a slow disk (and lots of tags, for
example) it can take several very annoying seconds (7.5s according to a
report by Carlos R. Mafra).
This avoids most of it by simply doing the filtering before looking up
the commits, by using the "raw" version of for_each_ref.

Relying on SVN::Core::INVALID_REVNUM (-1) as the "start"
argument to SVN::Ra::get_log() proved unreliable with http(s)
URLs so the result of SVN::Ra::get_latest_revnum() is used as
the "start" argument instead.

f8948e2 (remote prune: warn dangling symrefs, 2009-02-08) introduced a
more dangerous variant of for_each_ref() family that skips the check for
dangling refs, but it also made another unrelated check optional by
mistake.
The check to see if a ref points at 0{40} is not about brokenness, but is
about a possible future plan to represent a deleted ref by writing 40 "0"
in a loose ref when there is a stale version of the same ref already in
.git/packed-refs, so that we can implement deletion of a ref without
having to rewrite the packed refs file excluding the ref being deleted.
This check has to live outside of the conditional.

The "action" parameters for these two tests were supplied incorrectly for
the way the tests were implemented. The tests check whether a program
which calls hstrerror() or basename() successfully links when -lresolv or
-lgen are used, respectively. A successful linking would result in
NEEDS_RESOLV or NEEDS_LIBGEN being unset, and failure would result in
setting the respective variable.
Aside from that issue, the tests did not handle the case where neither
library was necessary for accessing the functions in question. So solve
both of these issues by re-working the two tests so that their form is like
the NEEDS_SOCKET test which attempts to link with just the c library, and
if it fails then assumes that the additional library is necessary and sets
the appropriate variable.
Also an entry in the config.mak.in file is necessary for the NEEDS_LIBGEN
variable to appear in the config.mak.autogen file with the value assigned
by the configure script. Without it, the generated shell script would
contain a snippet like this:
for ac_lib in ; do
...
which is incorrect.

It is useful to grep directories non-recursively, e.g. when one wants to

This patch adds support for --max-depth <depth> option to git-grep. If it is

specified on the command line.
Note that if path specified on command line contains wildcards, this option
makes no sense, e.g.
$ git grep -l --max-depth 0 GNU -- 'contrib/*'
(note the quotes) will search all files in contrib/, even in
subdirectories, because '*' matches all files.

If a patch adds a new line to the end of a file and this line ends with
one trailing whitespace character and has no newline, then
'--whitespace=fix' currently does not remove that trailing whitespace.
This patch fixes this by removing the check for trailing whitespace at

When combine-diff inspected the diff from one parent to the merge result,
it misinterpreted a header in the form @@ -l,k +0,0 @@.
This hunk header means that K lines were removed from the beginning of the
file, so the lost lines must be queued to the sline that represents the
first line of the merge result, but we incremented our pointer incorrectly
and ended up queuing it to the second line, which in turn made the lossage

happen after all the existing matches (in this case "two"). The code used
a naïve O(n^2) algorithm to compute this by scanning the whole removal

This patch remembers where the next scan should be started in the existing

In a rebase with --onto, the correct test for whether we can skip
rewriting a commit is if it is already on top of $ONTO, not $UPSTREAM.
Without --onto, this distinction does not exist and the behavior does
not change.
In a situation with two merged branches on a common base X:
X---o---o---o---M
\ /
x---x---x---x
Y
if we try to move the branches from their base on X to be based on Y,
so as to get
X
Y---o'--o'--o'--M'
\ /
x'--x'--x'--x'
then we fail. The command `git rebase -p --onto Y X M` moves only the
first-parent chain, like so:
X
\
x---x---x---x
\
Y---o'--o'--o'--M'
because it mistakenly drops the other branch(es) x---x---x---x from
the TODO file. This tests and fixes this behavior.

This patch respects and sets the rev.shown_one member to
prepend a blank line before showing a second item. We use
this member of rev_info instead of a local flag, because the
log_tree_commit we call into for showing commits already
respects and sets that flag. Meaning that everything will be
spaced properly if you intermix commits and tags, like:
$ git show v1.6.3 v1.6.2 HEAD
In that case, a single blank line will separate the first
tag, the commit it points to, the second tag, the commit
that one points to, and the final commit.
While we're at it, let's also support trees, so that even
something as crazy as
$ git show HEAD^{tree} HEAD~1^{tree} HEAD
will also be spaced in an easy-to-read way. However, we
intentionally do _not_ insert blank lines for blobs, so
that specifying multiple blobs gives a strict concatenation.

When showing a tag, our header parsing finishes with the
offset pointing to the newline separating the tag header
from the tag body. This means that the printed body will
always start with a newline.
However, we also add an extra newline when printing the

$ git show v1.6.3

This patch removes the extra newline from the end of the
tagger headers. This is a better solution than suppressing
the separator newline, because it retains the behavior for
tags which have no tagger. E.g., "git show v0.99" will
continue to look like:
$ git show v0.99
tag v0.99

You cannot do a "git pull --rebase" with a rebased upstream, if you have

In other words, find the fork point of the current branch, where
the tip of upstream branch used to be, and use it as the upstream
parameter of "git rebase".
This patch computes the fork point by walking the reflog to find the first
commit which is an ancestor of the current branch. Maybe there are

When we switch branches with "checkout -f", unpack_trees() feeds two
cache_entries to oneway_merge() function in its src[] array argument. The
zeroth entry comes from the current index, and the first entry represents
what the merge result should be, taken from the tree recorded in the
commit we are switching to.
When we have a blob (either regular file or a symlink) in the index and in
the work tree at path "foo", and the switched-to tree has "foo/bar",
i.e. "foo" becomes a directory, src[0] is obviously that blob currently
registered at "foo". Even though we do not have anything at "foo" in the
switched-to tree, src[1] is _not_ NULL in this case.
The unpack_trees() machinery places a special marker df_conflict_entry
to signal that no blob exists at "foo", but it will become a directory
that may have somthing underneath it (namely "foo/bar"), so a usual 3-way
merge can notice the situation.
But oneway_merge() codepath failed to notice this and passed the special
marker directly to merged_entry(). This happens to remove the "foo" in
the end because the df_conflict_entry does not have any name (hence the
"error" message) and its addition in add_index_entry() is rejected, but it
is wrong.

Some mailing lists are configured add prefix "[listname] " to all their

We cannot stop people from mucking with the subject line, and with the

happens. People have depended on the leading [bracketed string] removal.
In our 'oneway_merge()' we always do an 'lstat()' to see if we might
need to mark the entry for updating.
But we really shouldn't need to do that when the cache entry is already
marked as being ce_uptodate(), and this makes us do unnecessary lstat()

For some reason, I ended up doing
git show HEAD~5..
as an odd way of asking for a log. I realize I should just have used "git
log", but at the same time it does make perfect conceptual sense. After
all, you _could_ have done
git show HEAD HEAD~1 HEAD~2 HEAD~3 HEAD~4
and saying "git show HEAD~5.." is pretty natural. It's not like "git show"
only ever showed a single commit (or other object) before either! So
conceptually, giving a commit range is a very sensible operation, even
though you'd traditionally have used "git log" for that.
However, doing that currently results in an error
fatal: object ranges do not make sense when not walking revisions
which admittedly _also_ makes perfect sense - from an internal git
implementation standpoint in 'revision.c'.
However, I think that asking to show a range makes sense to a user, while
saying "object ranges no not make sense when not walking revisions" only
makes sense to a git developer.
So on the whole, of the two different "makes perfect sense" behaviors, I
think I originally picked the wrong one. And quite frankly, I don't really
see anybody actually _depending_ on that error case. So why not change it?
So rather than error out, just turn that non-walking error case into a
"silently turn on walking" instead.
