Lacking reliable symlinks, the instructions in the tutorial did not work
in a cygwin setup. Also, a few outputs were not correct.
This patch fixes these, and adds a test case which follows the
instructions of the tutorial (except git-clone, -fetch and -push, which I
have not done yet).

Make sure 'make install' does not have to rebuild templates.
The dependency rule in templates directory forced 'make install'
that immediately followed 'make all' to rebuild boilerplates.
This was problematic for a workflow that built first as yourself
and then installed as root, from a working tree that is on an
NFS mounted filesystem that is unwritable by root.
git-status truncates filenames up to the first occurrence of a whitespace
character when displaying. More precisely, it displays the filename up to any
field seperator defined in $IFS.
This patch fixes a bug in git-ls-tree in which the wrong filenames are
listed if the exact same file and directory contents are present in
another location in the tree.
Added a new series of test cases for directory and filename handling.

upload-pack: Do not choke on too many heads request.
Cloning from a repository with more than 256 refs (heads and tags
included) will choke, because upload-pack has a built-in limit of
feeding not more than MAX_NEEDS (currently 256) heads to underlying
git-rev-list. This is a problem when cloning a repository with many
tags, like http://www.linux-mips.org/pub/scm/linux.git, which has 290+
tags.
This commit introduces a new flag, --all, to git-rev-list, to include
all refs in the repository. Updated upload-pack detects requests that
ask more than MAX_NEEDS refs, and sends everything back instead.
We may probably want to tweak the definitions of MAX_NEEDS and
MAX_HAS, but that is a separate topic.
When we updated the marker for new files from 'N' to 'A', we forgot to
notice that the letter is already taken by the All-Or-None mark.
Change the All-Or-None marker to '*' to resolve this conflict.
git-diff-tree -r --diff-filter='R*' -M

that have renames, in comparison with:
git-diff-tree -r --diff-filter='R' -M
shows the same set of changes but the diff output are limited only to
renaming changes.
There was a leftover use of sed that attempted to remove the commit ID
output from git-diff-tree, which turned into an expensive no-op when
git-diff-tree output header format changed about three months ago.
Drop it.
Error message from get_sha1() on ambiguous short SHA1.
Unlike cases where "no such object exists", the case where specified

[PATCH] Enable and fix support for base less merges.
Let the merge strategies handle the base less case if they are able to
do it. It also fixes git-resolve.sh to die if no common ancestors
exists, instead of doing the wrong thing. Furthermore, it contains a
small independent fix for git-merge.sh and a fix for a base less code
path in gitMergeCommon.py.
With this it's possible to use
git merge -s recursive 'merge message' A B
to do a base less merge of A and B.

This makes "git-update-index" avoid the new index file write if it didn't
make any changes to the index.
It still doesn't make things like "git status" be read-only operations in

least avoid making unnecessary changes.

Instead of "git status" ignoring (and hiding) potential errors from the
"git-update-index" call, make it exit if it fails, and show the error.
In order to do this, use the "-q" flag (to ignore not-up-to-date files)
and add a new "--unmerged" flag that allows unmerged entries in the index
without any errors.
This also avoids marking the index "changed" if an entry isn't actually
modified, and makes sure that we exit with an understandable error message
if the index is corrupt or unreadable. "read_cache()" no longer returns an
error for the caller to check.
Finally, make die() and usage() exit with recognizable error codes, if we
ever want to check the failure reason in scripts.

This adds the counterpart of git-update-ref that lets you read
and create "symbolic refs". By default it uses a symbolic link
to represent ".git/HEAD -> refs/heads/master", but it can be compiled
to use the textfile symbolic ref.
The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah
.git/HEAD' have been converted to use new git-symbolic-ref command, so
that they can deal with either implementation.
[PATCH] Allow reading "symbolic refs" that point to other refs
This extends the ref reading to understand a "symbolic ref": a ref file
that starts with "ref: " and points to another ref file, and thus
introduces the notion of ref aliases.
This is in preparation of allowing HEAD to eventually not be a symlink,
but one of these symbolic refs instead.
[jc: Linus originally required the prefix to be "ref: " five bytes
and nothing else, but I changed it to allow and strip any number of
leading whitespaces to match what update-ref.c does.]

Teach update-ref about a symbolic ref stored in a textfile.
A symbolic ref is a regular file whose contents is "ref:", followed by
optional leading whitespaces, followed by a GIT_DIR relative pathname,
followed by optional trailing whitespaces (the optional whitespaces
are unconditionally removed, so you cannot have leading nor trailing
whitespaces). This can be used in place of a traditional symbolic
link .git/HEAD that usually points at "refs/heads/master". You can
instead have a regular file .git/HEAD whose contents is
"ref: refs/heads/master".
[jc: currently the code does not enforce the symbolic ref to begin with
refs/, unlike the symbolic link case. It may be worthwhile to require
either case to begin with refs/ and not have any /./ nor /../ in them.]
[jc: The original by Linus fetched and overwrote branch heads with
--all, which felt dangerous and wrong, so I removed it. Also this
version does not use any refs that resulted as --tags for later
merge. ]

Add the sanity checks discussed on the list with Nick Hengeveld in

* unlink of previous and rename from temp to previous can fail for
reasons other than benign ones (missing previous and missing temp).
Report these failures when we encounter them, to make diagnosing
problems easier.

truncate the file.

The archive generated with git-tar-tree had 0755 and 0644 mode bits.

A patch that contains no actual diff, and that doesn't change any
meta-data is bad. It shouldn't be a patch at all, and git-apply shouldn't
just accept it.
This caused a corrupted patch to be silently applied as an empty change in
the kernel, because the corruption ended up making the patch look empty.
An example of such a patch is one that contains the patch header, but
where the initial fragment header (the "@@ -nr,.." line) is missing,
causing us to not parse any fragments.
The real "patch" program will also flag such patches as bad, with the
message
patch: **** Only garbage was found in the patch input.

After seeing Jeff's guide, I changed my mind about the
big-rename transition plan. Even if Porcelains are kept up to
date, those web documents that describes older world order would
live longer and people will stumble across them via google
searches. And who knows how many mirrored copies there are.
The backward compatible symbolic links *will* be removed before
1.0. But that will not happen in 0.99.8.
This again makes git-pull to use git-merge, so that different merge
strategy can be specified from the command line. Without explicit
strategy parameter, it defaults to git-merge-resolve if only one
remote is pulled, and git-merge-octopus otherwise, to keep the
default behaviour of the command the same as the original.
Also this brings another usability measure: -n flag from the command
line, if given, is passed to git-merge to prevent it from running the
diffstat at the end of the merge.
This uses the git-update-ref command in scripts for safer updates.
Also places where we used to read HEAD ref by using "cat" were fixed
to use git-rev-parse. This will matter when we start using symbolic
references.

The refspecs specified in the .git/remotes/<remote> on the "Pull: "
lines are for fetching multiple heads in one go, but most of the time
making an Octopus out of them is not what is wanted. Make git-fetch
leave the marker in .git/FETCH_HEAD file so that later stages can
tell which heads are for merging and which are not.
Tom Prince made me realize how stupid the original behaviour was.
It still talked about "the proposed alternative semantics" but we have
used those alternative semantics for quite some time. Update them to
avoid confusion.
The new option --stdin reads list of paths to be updated from the
standard input. As usual, -z means the paths are terminated with NUL
characters, as opposed to LF without that option.
This is useful to use git-diff-files -z and git-ls-files -z when the
platform xargs does not support -0 option, and obviously saves one
process even when xargs can take -0.
With the --recover option, we verify that we have absolutely
everything reachable from the target, not assuming that things
reachable from refs will be complete.

Do not require clean tree when reverting and cherry-picking.
My stupidity deserved to be yelled at by Linus ... there is no reason
to require the working tree to be clean when merging -- the only
requirements are index to match HEAD commit and the paths involved in
merge are up to date in the working tree. Revert and cherry-pick are
just specialized forms of merge, and the requirements should be the
same.
Remove the 'general purpose routine to make sure tree is clean' from
git-sh-setup, to prevent me from getting tempted again.
Being able to try multiple strategies and automatically picking one
that seems to give less conflicting result may or may not much sense
in practice. At least that should not force normal use case to
additionally require the working tree to be fully clean. As Linus
shouted, local changes do not matter unless they interfere with the
merge.
This commit changes git-merge not to require a clean working tree.
Only when we will iterate through more than one merge strategies,
local changes are stashed away before trying the first merge, and
restored before second and later merges are attempted.
The index file must be in sync with HEAD in any case -- otherwise the
merge result would contain changes since HEAD that was done locally
and registered in the index. This check is already enforced by
three-way read-tree existing merge strategies use, but is done here as
a safeguard as well.
