git-mergetool: Make default selection of merge-tool more intelligent
Make git-mergetool prefer meld under GNOME, and kdiff3 under KDE. When
considering emerge and vimdiff, check $VISUAL and $EDITOR to see which the
user might prefer.
When refactoring code to split one iteration of a too deeply
nested loop into a separate function, it inevitably makes the
indentation levels shallower (that's the sole point of such a
refactoring). With "git blame -w", you can ignore such
re-indentation and pass blame for such moved lines to the
parent.
When two branches are merged that modify a subdirectory (possibly in
different intermediate steps) such that both end up identical, then
rev-list chooses only one branch. But when we filter history, we want to
keep both branches. Therefore, we must use --full-history.

With git-filter-branch --subdirectory-filter <subdirectory> you can
get at the history, as seen by a certain subdirectory. The history
of the rewritten branch will only contain commits that touched that
subdirectory, and the subdirectory will be rewritten to be the new
project root.

remote.c: "git-push frotz" should update what matches at the source.
Earlier, when the local repository has a branch "frotz" and the
remote repository has a tag "frotz" (but not branch "frotz"),
"git-push frotz" mistakenly updated the tag at the remote side.
This was because the partial refname matching code was applied
independently on both source and destination side.
With this fix, when a colon-less refspec is given to git-push,
we first match it with the refs in the source repository, and
update the matching ref in the destination repository.
remote.c: fix "git push" weak match disambiguation
When "git push A:B" is given, and A (or B) is not a full refname
that begins with refs/, we require an unambiguous match with an
existing ref. For this purpose, a match with a local branch or
a tag (i.e. refs/heads/A and refs/tags/A) is called a "strong
match", and any other match is called a "weak match". A partial
refname is unambiguous when there is only one strong match with
any number of weak matches, or when there is only one weak match
and no other match.
However, as reported by Sparse with Ramsay Jones recently,
count_refspec_match() function had a bug where a variable in an
inner block masked a different variable of the same name, which
caused the weak matches to be ignored.
When checking what ref the source refspec matches, we have no
business setting the default for the destination, so move that
code lower. Also simplify the result from the code block that
matches the source side by making it set matched_src only upon
unambiguous match.
Make command description imperative statement, not third-person present.
In several of the text messages, the tense of the verb is inconsistent.
For example, "Add" vs "Creates". It is customary to use imperative for
command description.
Make git-cvsserver understand some options inspired by
git-daemon, namely --base-path, --export-all, --strict-paths.
Also allow the caller to specify a whitelist of allowed
directories, again similar to git-daemon.
While already adding option parsing also support the common
--help and --version options.
Rationale:
While the gitcvs.enabled configuration option already
offers means to limit git-cvsserver access to a repository,
there are some use cases where other methods of access
control prove to be more useful.
E.g. if setting up a pserver for a collection of public
repositories one might want limit the exported repositories
to exactly the directory this collection is located whithout
having to worry about other repositories that might lie around
with the configuration variable set (never trust your users ;)

cvsserver: Make req_Root more critical of its input data
The path submitted with the Root request has to be absolute
(cvs does it this way and it may save us some sanity checks
later)
If multiple roots are specified (e.g. because we use
pserver authentication which will already include the
root), ensure that they say all the same.
Probably neither is a security risk, and neither should ever
be triggered by a sane client, but when validating
input data, it's better to be save than sorry.

checkout: do not get confused with ambiguous tag/branch names
Although it is not advisable, we have always allowed a branch
and a tag to have the same basename (i.e. it is not illegal to
have refs/heads/frotz and refs/tags/frotz at the same time).
When talking about a specific commit, the interpretation of
'frotz' has always been "use tag and then check branch",
although we warn when ambiguities exist.
However "git checkout $name" is defined to (1) first see if it
matches the branch name, and if so switch to that branch; (2)
otherwise it is an instruction to detach HEAD to point at the
commit named by $name. We did not follow this definition when
$name appeared under both refs/heads/ and refs/tags/ -- we
switched to the branch but read the tree from the tagged commit,
which was utterly bogus.
will consider references in "refs/heads" of the remote repository
"remote-name", instead of the ones in "refs/remotes/other", which
the given refspec clearly means.

Currently git-cvsimport tries to create tag objects directly via git-mktag
in a very broken way, e.g the stuff it writes into the tagger field of
the tag object doesn't really resemble the GIT_COMMITTER_IDENT. This makes
gitweb and possibly other tools that try to interpret tag objects to be
confused about tag date and authorship.
Fix this by calling git-tag instead. This also has a nice side effect of
not creating the tag object but only the lightweight tag as that's the only
thing CVS has anyways.

setup_gdg is used as abbreviation for setup_git_directory_gently.
The work tree can be specified using the environment variable
GIT_WORK_TREE and the config option core.worktree (the environment
variable has precendence over the config option). Additionally
there is a command line option --work-tree which sets the
environment variable.
setup_gdg does the following now:
GIT_DIR unspecified
repository in .git directory
parent directory of the .git directory is used as work tree,
GIT_WORK_TREE is ignored
GIT_DIR unspecified
repository in cwd
GIT_DIR is set to cwd
see the cases with GIT_DIR specified what happens next and
also see the note below
GIT_DIR specified
GIT_WORK_TREE/core.worktree unspecified
cwd is used as work tree
GIT_DIR specified
GIT_WORK_TREE/core.worktree specified
the specified work tree is used
Note on the case where GIT_DIR is unspecified and repository is in cwd:
GIT_WORK_TREE is used but is_inside_git_dir is always true.
I did it this way because setup_gdg might be called multiple
times (e.g. when doing alias expansion) and in successive calls
setup_gdg should do the same thing every time.
Meaning of is_bare/is_inside_work_tree/is_inside_git_dir:
(1) is_bare_repository
A repository is bare if core.bare is true or core.bare is
unspecified and the name suggests it is bare (directory not
named .git). The bare option disables a few protective
checks which are useful with a working tree. Currently
this changes if a repository is bare:
updates of HEAD are allowed
git gc packs the refs
the reflog is disabled by default
(2) is_inside_work_tree
True if the cwd is inside the associated working tree (if there
is one), false otherwise.
(3) is_inside_git_dir
True if the cwd is inside the git directory, false otherwise.
Before this patch is_inside_git_dir was always true for bare
repositories.
When setup_gdg finds a repository git_config(git_default_config) is
always called. This ensure that is_bare_repository makes use of
core.bare and does not guess even though core.bare is specified.
inside_work_tree and inside_git_dir are set if setup_gdg finds a
repository. The is_inside_work_tree and is_inside_git_dir functions
will die if they are called before a successful call to setup_gdg.

The map() function can be used by filters to map a commit id to its

In the rewrite loop, this mapping is also needed, but was done

filter-branch: Use rev-list arguments to specify revision ranges.
A subset of commits in a branch used to be specified by options (-k, -r)
as well as the branch tip itself (-s). It is more natural (for git users)
to specify revision ranges like 'master..next' instead. This makes it so.
If no range is specified it defaults to 'HEAD'.
As a consequence, the new name of the filtered branch must be the first
non-option argument. All remaining arguments are passed to 'git rev-list'
unmodified.
The tip of the branch that gets filtered is implied: It is the first
commit that git rev-list would print for the specified range.

cvsimport: add support for new style remote layout
cvsimport creates any branches found in the remote CVS repository
in the refs/heads namespace. This makes sense for a repository
conversion. When using git as a sane interface to a remote CVS
repository, that repository may well remain as the 'master'
respository. In this model it makes sense to import the CVS
repository into the refs/remotes namespace.
Add a new option '-r <remote>' to set the remote name for
this import. When this option is specified branches are named
refs/remotes/<remote>/branch, with HEAD named as master matching
git-clone separate remotes layout. Without branches are placed
ion refs/heads, with HEAD named origin as before.
