Now ref creation codepath in lock_ref_sha1() and friends notices
the directory/file conflict situation, we do not do this by hand
in git-branch anymore.
This implements deletion of a packed ref. Since it is a very
rare event to delete a ref compared to looking up, creating and
updating, this opts to remove the ref from the packed-ref file
instead of doing any of the filesystem based "negative ref" trick
to optimize the deletion path.
lock_ref_sha1(): do not sometimes error() and sometimes die().
This cleans up the error path in the function so it does not
die() itself sometimes while signalling an error with NULL some
other times which was inconsistent and confusing.
Once we read packed and loose refs, for_each_ref() and friends
kept using them even after write_ref_sha1() and delete_ref()
changed the refs. This adds invalidate_cached_refs() as a way
to flush the cached information.
ref locking: allow 'foo' when 'foo/bar' used to exist but not anymore.
It is normal to have .git/refs/heads/foo directory which is
empty after the last branch whose name starts with foo/ is
removed. Make sure we notice this case and allow creation of
branch foo by removing the empty directory.
gitweb: tree view: hash_base and hash are now context sensitive
In tree view, by default, hash_base is HEAD and hash is the

git-diff/git-apply: make diff output a bit friendlier to GNU patch (part 1)
Somebody was wondering on #git channel why a git generated diff
does not apply with GNU patch when the filename contains a SP.
It is because GNU patch expects to find TAB (and trailing timestamp)
on ---/+++ (old_name and new_name) lines after the filenames.
The "diff --git" output format was carefully designed to be
compatible with GNU patch where it can, but whitespace
characters were always a pain.
We can make our output a bit more GNU patch friendly by adding an
extra TAB (but not trailing timestamp) to old/new name lines when
the filename as a SP in it. This updates git-apply to prepare
ourselves to accept such a patch, but we still do not generate
output that is patch friendly yet. That change needs to wait
until everybody has this change.
When a filename contains a real tab, "diff --git" format
always c-quotes it as discussed on the list with GNU patch
maintainer previously:
The distinction between BASIC_ vs ALL_ is still kept, since it
is not Git.xs specific -- we could face the same issue when we
do other language bindings (e.g. Python).
Fix approxidate() to understand 12:34 AM/PM are 00:34 and 12:34
It just simplifies the whole thing to say
"hour = (hour % 12) + X"
where X is 12 for PM and 0 for AM.
It also fixes the "exact date" parsing, which didn't parse AM at all, and
as such would do the same "12:30 AM" means "12:30 24-hour-format" bug. Of
course, I hope that no exact dates use AM/PM anyway, but since we support
the PM format, let's just get it right.

diff --stat: ensure at least one '-' for deletions, and one '+' for additions
The number of '-' and '+' is still linear. The idea is that
scaled-length := floor(a * length + b) with the following constraints: if
length == 1, scaled-length == 1, and the combined length of plusses
and minusses should not be larger than the width by a small margin. Thus,
a + b == 1
and
a * max_plusses + b + a * max_minusses + b = width + 1
The solution is
a * x + b = ((width - 1) * (x - 1) + max_change - 1)
/ (max_change - 1)

gitweb: Don't use quotemeta on internally generated strings
Do not use quotemeta on internally generated strings
such as filenames of snapshot, blobs, etc.
quotemeta quotes any characters not matching /A-Za-z_0-9/.
Which means that we get strings like this:
When displaying a list of rows (difftree, shortlog, etc),
the first entry is now printed shaded, i.e. alternate is
initialized to 1, as opposed to non-shaded (alternate
initialized to 0).
This solves the problem when there is only one row to
display -- it is displayed shaded to visually indicate that
it is "active", part of a "list", etc.
(Compare this to the trivial case of more than one entry,
where the rows have alternating shade, thus suggesting
being part of a "list" of "active" entries, etc.)

svnimport: add support for parsing From: lines for author
When commiting a non-signed off contribution you cannot just add
a Signed-off-by: from the author as they did not sign it off.
But if you then commit it, and necessarily sign it off yourself,
the change appears to be yours. In this case it is common to use
the following form:
Commentry
From: originator <email> Signed-of-by: me <my email>
Now that we have support for parsing Signed-off-by: for author
information it makes sense to handle From: as well. This patch
adds a new -F which will handle From: lines in the comments. It
may be used in combination with -S.

Contributed bash completion support for core Git tools.
This is a set of bash completion routines for many of the
popular core Git tools. I wrote these routines from scratch
after reading the git-compl and git-compl-lib routines available
from the gitcompletion package at http://gitweb.hawaga.org.uk/
and found those to be lacking in functionality for some commands.
Consequently there may be some similarities but many differences.
Since these are completion routines only for tools shipped with
core Git and since bash is a popular shell on many of the native
core Git platforms (Linux, Mac OS X, Solaris, BSD) including these
routines as part of the stock package would probably be convienent
for many users.

When creating branch c/d check that branch c does not already exists.
With packed refs, there may not be a ".git/refs/heads/c" file
when branch c exists. And currently in this case, there is no check
to prevent creation of branch c/d.
This should probably be rewritten in C and done after the ref lock
has been taken to make sure no race exists though.

grep: fix --fixed-strings combined with expression.
"git grep --fixed-strings -e GIT --and -e VERSION .gitignore"
misbehaved because we did not notice this needs to grab lines
that have the given two fixed strings at the same time.
and then grafts them together to make B0 a child of A2. So
the final history looks like (time flows from top to bottom):
true parent touches subdir?
A0 none yes (creates it)
A1 A0 no
A2 A1 yes
B0 none yes (different from what's in A2)
B1 B0 no
B2 B1 yes
"git rev-list --parents --pretty=raw B2" would give "fake"
parents on the "commit " header lines while "parent " header
lines show the parent as recorded in the commit object (i.e. B0
appears to have A2 as its parent on "commit " header but there
is no "parent A2" header line in it).
When you have path limiters, we simplify history to omit
commits that do not affect the specified paths.
So "git rev-list --parents --pretty=raw B2 subdir" would return
"B2 B0 A2 A0" (because B1 and A1 do not touch the path). When
it does so, the "commit " header lines have "fake" parents
(i.e. B2 appears to have B0 as its parent on "commit " header),
but you can still get the true parents by looking at "parent "
header.
This converts receive-pack to use the standard ref locking code
instead of its own. As a side effect, it automatically records
the "push" event to ref-log if enabled.
This updates the use of git-update-ref in git-branch, git-tag
and git-commit to make them safer in a few corner cases as
demonstration.
- git-tag makes sure that the named tag does not exist, allows
you to edit tag message and then creates the tag. If a tag
with the same name was created by somebody else in the
meantime, it used to happily overwrote it. Now it notices
the situation.
- git-branch -d and git-commit (for the initial commit) had the
same issue but with smaller race window, which is plugged
with this.
This adds -d flag to update-ref to allow safe deletion of ref.
Before deleting it, the command checks if the given <oldvalue>
still matches the value the caller thought the ref contained.
Similarly, it also accepts 0{40} or an empty string as <oldvalue>
to allow safe creation of a new ref.

I've seen some users get into situtations where their HEAD
symbolic-ref is pointing at a non-existant ref. (Sometimes this
happens during clone when the remote repository lacks a 'master'
branch.) If this happens the user is unable to use git-checkout
to switch branches as there is no prior commit to merge from.
So instead of giving the user low-level errors about how HEAD
can't be resolved and how not a single revision was given change
the type of checkout to be a force and go through with the user's
request anyway.

let the GIT native protocol use offsets to delta base when possible
There is no reason not to always do this when both ends agree.

pack data reuse yet.
The idea is to allow for the fetch protocol to use an extension flag
to notify the remote end that --delta-base-offset can be used with
git-pack-objects. Eventually git-repack will always provide this flag.
With this, all delta base objects are now pushed before deltas that depend
on them. This is a requirements for OBJ_OFS_DELTA. This is not a

This adds a new object, namely OBJ_OFS_DELTA, renames OBJ_DELTA to
OBJ_REF_DELTA to better make the distinction between those two delta
objects, and adds support for the handling of those new delta objects
in sha1_file.c only.
The OBJ_OFS_DELTA contains a relative offset from the delta object's
position in a pack instead of the 20-byte SHA1 reference to identify
the base object. Since the base is likely to be not so far away, the
relative offset is more likely to have a smaller encoding on average
than an absolute offset. And for those delta objects the base must
always be stored first because there is no way to know the distance of
later objects when streaming a pack. Hence this relative offset is
always meant to be negative.
The offset encoding is slightly denser than the one used for object
size -- credits to <linux@horizon.com> (whoever this is) for bringing
it to my attention.
This allows for pack size reduction between 3.2% (Linux-2.6) to over 5%
(linux-historic). Runtime pack access should be faster too since delta
replay does skip a search in the pack index for each delta in a chain.

So clicking repeatedly on "Prev" would show you the blame

of that particular line whose "Prev" you're clicking on.
The "Diff" column shows "Diff" which is a link to blobdiff
between "Prev" and "Commit" commits _for that line_.
