gitweb: Fix 'history' view for deleted files with history
When asked for history of a file which is not present in given branch
("HEAD", i.e. current branch, or given by transient $hash_hase ('hb')
parameter), but is present deeper in the history (meaning that "git
rev-list --full-history $hash_base -- $file_name" is not empty), and
there is no $hash ('h') parameter set for a file, gitweb would spew
multiple of "Use of uninitialized value" warnings, and some links
would be missing. This commit fixes this bug.
This bug occurs in the rare cases when "git log -- <path>" is empty
and "git log --full-history -- <path>" is not, or to be more exact in
the cases when full-history starts later than given branch. It can
happen if you are using handcrafted gitwb URL, or if you follow
generic 'history' link or bookmark for a file which got deleted.
Gitweb tried to get file type ('tree', or 'blob', or even 'commit')
from the commit we start searching from (where the file was not
present), and not among found commits. This was the cause of "Use of
uninitialized value" warnings.
This commit also add tests for such situation to t9500 test.
While we are it, return HTTP error if there is _no_ history; it means
that file or directory was not found (for given branch). Also error
out if type of item could not be found: it should not happen now, but
better be sure.

Document that WebDAV doesn't need git on the server, and works over SSL
I managed to set up a Git repository on a preconfigured WebDAV server,
and using HTTPS, without installing Git on it or changing the server
configuration. This works through a proxy too. This patch reflects
this (it previously stated that Git was _necessary_ on the server,
which isn't true). Also give a few hints to troubleshoting.

git-remote: reject adding remotes with invalid names
This can happen if the arguments to git-remote add is switched by the

Fix it by using the refspec parsing engine to check if the requested

git-bisect: make "start", "good" and "skip" succeed or fail atomically
Before this patch, when "git bisect start", "git bisect good" or
"git bisect skip" were called with many revisions, they could fail
after having already marked some revisions as "good", "bad" or
"skip".
This could be especilally bad for "git bisect start" because as
the file ".git/BISECT_NAMES" would not have been written, there
would have been no attempt to clear the marked revisions on a
"git bisect reset". That's because if there is no
".git/BISECT_NAMES" file, nothing is done to clean things up, as
the bisect session is not supposed to have started.
While at it, let's also create the ".git/BISECT_START" file, only
after ".git/BISECT_NAMES" as been created.

When the Subject: line is empty for whatever reason, git-am was fooled by
it and left an empty line at the beginning of the resulting commit log
message.
This moves the logic around so that we do not keep $SUBJECT in a separate
variable. Instead, $dotest/msg-clean, which used to be the log message
body extracted from the message and then trailing whitespaces cleansed
out, now contains the subject line followed by a blank line at the
beginning for normal messages, and we use the first line from the file as
the summary line throughout the program.

bisect: squelch "fatal: ref HEAD not a symref" misleading message
To get the current HEAD when we start bisecting using for example
"git bisect start", we first try "git symbolic-ref HEAD" to get a
nice name, and if it fails, we fall back to "git rev-parse
--verify HEAD".
The problem is that when "git symbolic-ref HEAD" fails, it
displays "fatal: ref HEAD not a symref", so it looks like "git
bisect start" failed and does not accept detached HEAD, even if
in fact it worked fine.
This patch adds "-q" option to the "git symbolic-ref" call to
get rid of the misleading error message.

Clarify documentation of git-cvsserver, particularly in relation to git-shell
For SSH clients restricted to git-shell, CVS_SERVER does not have to be
specified, because git-shell understands the default value of 'cvs' to
mean git-cvsserver'. This makes it totally transparent to CVS users, but
the instruction to set up CVS access for people with real shell access
does not apply.
Previous wording mentioning GIT_AUTHOR, GIT_COMMITTER variables was
unclear that we really meant GIT_AUTHOR_(NAME|EMAIL), etc.
Note that the .ssh/environment file is a good place to set these, and that
the .bashrc is shell-specific. Add a bit of text to differentiate cvs -d
(setting CVSROOT) from cvs co -d (setting the name of the newly checked
out directory). Removed an extra 'Example:' string.

When git clean is run from a subdirectory it should follow the normal

The fix is to send len which could be shorter than ent->len because we

git-submodule - possibly use branch name to describe a module
This changes the search logic for describing a submodule from:
- annotated tag
- any tag
- tag on a subsequent commit
- commit id
to
- annotated tag
- any tag
- tag on a subsequent commit
- local or remote branch
- commit id
The change is describing with respect to a branch before falling
back to the commit id. By itself, git-submodule will maintain submodules
as headless checkouts without ever making a local branch. In
general, such heads can always be described relative to the remote branch
regardless of existence of tags, and so provides a better fallback
summary than just the commit id.
This requires inserting an extra describe step as --contains is
incompatible with --all, but the latter can be used with --always
to fall back to a commit ID. Also, --contains implies --tags, so the
latter is not needed.

It seems that "git bisect good" and "git bisect skip" have never
properly checked arguments that have been passed to them. As soon
as one of them can be parsed as a SHA1, no error or warning would
be given.
This is because 'git rev-parse --revs-only --no-flags "$@"' always
"exit 0" and outputs all the SHA1 it can found from parsing "$@".
This patch fix this by using, for each "bisect good" argument, the
same logic as for the "bisect bad" argument.
While at it, this patch teaches "bisect bad" to give a meaningfull
error message when it is passed more than one argument.
Note that if "git bisect good" or "git bisect skip" is given some
proper revs and then something that is not a proper rev, then the
first proper revs will still have been marked as "good" or "skip".

There was code in update_local_ref for handling this case,

git-svn: fix following renamed paths when tracking a single path

With tcl/tk8.5 the lset command seems to behave differently. When

3. Then filter-branch invokes 'git clean' to remove exactly those
left-overs. But here it does not remove the directory.

diff-index: careful when inspecting work tree items
Earlier, if you changed a staged path into a directory in the work tree,
we happily ran lstat(2) on it and found that it exists, and declared that
the user changed it to a gitlink.
This is wrong for two reasons:
(1) It may be a directory, but it may not be a submodule, and in the
latter case, the change we need to report is "the blob at the path
has disappeared". We need to check with resolve_gitlink_ref() to be
consistent with what "git add" and "git update-index --add" does.
(2) lstat(2) may have succeeded only because a leading component of the
path was turned into a symbolic link that points at something that
exists in the work tree. In such a case, the path itself does not
exist anymore, as far as the index is concerned.
This fixes these breakages in diff-index that the previous patch has
exposed.
Add corner case tests for diff-index and diff-files
diff-index and diff-files can get confused in corner cases when an indexed
blob turns into something else in the work tree. This patch adds tests to
expose such breakages.
The test is classified under t2XXX series instead of t4XXX series, because
the ultimate objective is to fix "add -u" (and "commit -a" that shares the
same issue).
Allow git-cvsserver database table name prefix to be specified.

any non-alphabetic characters are replaced with underscores.
A typo found in contrib/completion/git-completion.bash is also fixed.
