da02ca508b check_path(): allow symlinked directories to checkout-index --prefix
Merlyn noticed that Documentation/install-doc-quick.sh no longer correctly
removes old installed documents when the target directory has a leading
path that is a symlink.  It turns out that "checkout-index --prefix" was
broken by recent b6986d8 (git-checkout: be careful about untracked
symlinks, 2009-07-29).

I suspect has_symlink_leading_path() could learn the third parameter
(prefix that is allowed to be symlinked directories) to allow us to retire
a similar function has_dirs_only_path().

Another avenue of fixing this I considered was to get rid of base_dir and
base_dir_len from "struct checkout", and instead make "git checkout-index"
when run with --prefix mkdir the leading path and chdir in there.  It
might be the best longer term solution to this issue, as the base_dir
feature is used only by that rather obscure codepath as far as I know.

But at least this patch should fix this breakage.

db137fe91e read-tree: Fix regression with creation of a new index file.
Reading the index into an empty file has been broken by
5a56da5806, since it causes the existing
index to always be loaded first, and dies if it's an empty file:

$ GIT_INDEX_FILE=`mktemp` git read-tree master
fatal: index file smaller than expected

It breaks for instance committing from git.el. This patch reverts to the
previous behavior of only loading the index when merging it.

13354f5377 docs: describe impact of repack on "clone -s"
The effects of repacking on a repository with alternates are a bit
subtle. The two main things users will want are:

  1. Not to waste disk space by accidentally copying objects which could
     be shared.

  2. Copying all objects explicitly to break the dependency on the source
     repo.

This patch describes both under the "clone -s" documentation. It makes
sense to put it there rather than in git-repack.txt for both cases.

For (1), we are warning the user who is using "clone -s" about what _not_
to do, so we need to get their attention when reading about "clone -s".

For (2), we are telling them how git-repack can be used to accomplish a
task, but until they know that git-repack is the right tool, they have no
reason to look at the repack documentation.

dda1f2a5c3 Implement 'git stash save --patch'
This adds a hunk-based mode to git-stash.  You can select hunks from
the difference between HEAD and worktree, and git-stash will build a
stash that reflects these changes.  The index state of the stash is
the same as your current index, and we also let --patch imply
--keep-index.

Note that because the selected hunks are rolled back from the worktree
but not the index, the resulting state may appear somewhat confusing
if you had also staged these changes.  This is not entirely
satisfactory, but due to the way stashes are applied, other solutions
would require a change to the stash format.

4f353658b9 Implement 'git checkout --patch'
This introduces a --patch mode for git-checkout.  In the index usage

  git checkout --patch -- [files...]

it lets the user discard edits from the <files> at the granularity of
hunks (by selecting hunks from 'git diff' and then reverse applying
them to the worktree).

We also accept a revision argument.  In the case

  git checkout --patch HEAD -- [files...]

we offer hunks from the difference between HEAD and the worktree, and
reverse applies them to both index and worktree, allowing you to
discard staged changes completely.  In the non-HEAD usage

  git checkout --patch <revision> -- [files...]

it offers hunks from the difference between the worktree and
<revision>.  The chosen hunks are then applied to both index and
worktree.

The application to worktree and index is done "atomically" in the
sense that we first check if the patch applies to the index (it should
always apply to the worktree).  If it does not, we give the user a
choice to either abort or apply to the worktree anyway.

d002ef4d94 Implement 'git reset --patch'
This introduces a --patch mode for git-reset.  The basic case is

  git reset --patch -- [files...]

which acts as the opposite of 'git add --patch -- [files...]': it
offers hunks for *un*staging.  Advanced usage is

  git reset --patch <revision> -- [files...]

which offers hunks from the diff between the index and <revision> for
forward application to the index.  (That is, the basic case is just
<revision> = HEAD.)

3d792161b1 add -p: do not attempt to coalesce mode changes
In 0392513 (add-interactive: refactor mode hunk handling, 2009-04-16),
we merged the interaction loops for mode changes and hunk staging.
This was fine at the time, because 0beee4c (git-add--interactive:
remove hunk coalescing, 2008-07-02) removed hunk coalescing.

However, in 7a26e65 (Revert "git-add--interactive: remove hunk
coalescing", 2009-05-16), we resurrected it.  Since then, the code
would attempt in vain to merge mode changes with diff hunks,
corrupting both in the process.

We add a check to the coalescing loop to ensure it only looks at diff
hunks, thus skipping mode changes.

5fd448f114 git stash: Give friendlier errors when there is nothing to apply
The change makes sure a stash (given or default) exists before
checking if the working tree is dirty.

If the default stash is requested, the old message was scary and
included a 'fatal' error from rev-parse:
     fatal: Needed a single revision
     : no valid stashed state found

It is replaced with a friendlier 'Nothing to apply' error, similar to
'git stash branch'.

If a specific stash is specified, the 'Needed a single revision' errors
from rev-parse are suppressed.

9a217391e9 Fix "unpack-objects --strict"
When unpack-objects is run under the --strict option, objects that have
pointers to other objects are verified for the reachability at the end, by
calling check_object() on each of them, and letting check_object to walk
the reachable objects from them using fsck_walk() recursively.

The function however misunderstands the semantics of fsck_walk() function
when it makes a call to it, setting itself as the callback.  fsck_walk()
expects the callback function to return a non-zero value to signal an
error (negative value causes an immediate abort, positive value is still
an error but allows further checks on sibling objects) and return zero to
signal a success.  The function however returned 1 on some non error
cases, and to cover up this mistake, complained only when fsck_walk() did
not detect any error.

To fix this double-bug, make the function return zero on all success
cases, and also check for non-zero return from fsck_walk() for an error.

9bf3acfada gitk: Parse arbitrary commit-ish in SHA1 field
We only accepted either SHA1s or heads/tags that have been read.  This
meant the user could not, e.g., enter HEAD to go back to the current
commit.

This adds code to call out to git rev-parse --verify if all other
methods of interpreting the string the user entered fail.
(git-rev-parse alone is not enough as we really want a single
revision.)

The error paths change slighly, because we now know from the rev-parse
invocation whether the expression was valid at all.  The previous
"unknown" path is now only triggered if the revision does exist, but
is not in the current view display.

2b1fbf90aa gitk: Fix direction of symmetric difference in optimized mode
ee66e08 (gitk: Make updates go faster, 2008-05-09) implemented an
optimized mode where gitk parses the arguments with rev-parse, and
manually reads history in chunks.  As mentioned in the commit message,
symmetric differences are a problem there:

    One wrinkle is that we have to turn symmetric diff arguments (of the
    form a...b) back into symmetric diff form so that --left-right still
    works, as git rev parse turns a...b into a b ^merge_base(a,b).

However, git-rev-parse returns a...b in the swapped order

    b a ^merge_base(a,b)

This has been the case since at least 1f8115b (the state of master at
the time of the abovementioned ee66e08; Merge branch 'maint',
2008-05-08).  So gitk flipped the sides of symmetric differences
whenever it was in optimized mode.

Fix this by swapping the sides of the reconstruction code.

the end users call via the "git" top-level program. We should refer them
as "git programs" when we discuss the fact that the commands are
implemented as separate programs, but in other contexts, it is better to
use the term "git commands" consistently.

merge only requires one <remote>, so "<remote>..." should be used in the

These two structures are of the same type, but we'd better be consistent.

19a7fcbf16 allow pull --rebase on branch yet to be born
When doing a "pull --rebase", we check to make sure that the index and
working tree are clean. The index-clean check compares the index against
HEAD. The test erroneously reports dirtiness if we don't have a HEAD yet.

In such an "unborn branch" case, by definition, a non-empty index won't
be based on whatever we are pulling down from the remote, and will lose
the local change.  Just check if $GIT_DIR/index exists and error out.

660231aa97 block-sha1: support for architectures with memory alignment restrictions
This is needed on architectures with poor or non-existent unaligned memory
support and/or no fast byte swap instruction (such as ARM) by using byte
accesses to memory and shifting the result together.

This also makes the code portable, therefore the byte access methods are
the defaults.  Any architecture that properly supports unaligned word
accesses in hardware simply has to enable the alternative methods.

dc52fd2973 block-sha1: split the different "hacks" to be individually selected
This is to make it easier for them to be selected individually depending
on the architecture instead of the other way around i.e. having each
architecture select a list of hacks up front.  That makes for clearer
documentation as well.
