t4030, t4031: work around bogus MSYS bash path conversion
Recall that MSYS bash converts POSIX style absolute paths to Windows style
absolute paths. Unfortunately, it converts a program argument that begins
with a double-quote and otherwise looks like an absolute POSIX path, but
in doing so, it strips everything past the second double-quote[*]. This
case is triggered in the two test scripts. The work-around is to place the
Windows style path returned by $(pwd) between the quotes to avoid the path
conversion.
[*] It is already bogus that a conversion is even considered when a program
argument begins with a double-quote because it cannot be an absolute POSIX
path.

Currently textconv helpers are run directly. Running through
the shell is useful because the user can provide a program
with command line arguments, like "antiword -f".
It also makes textconv more consistent with other parts of
git, most of which run their helpers using the shell.
The downside is that textconv helpers with shell
metacharacters (like space) in the filename will be broken.

On Windows, we need the shbang line to correctly invoke shell scripts via
a POSIX shell, except when the script is invoked via 'sh -c' because sh (a
bash) does "the right thing". But the clean and smudge filters will not
always be invoked via 'sh -c'; to futureproof, we should mark the the one
in t0021-conversion with #!$SHELL_PATH.

The %.o: %.S pattern rule should depend on GIT-CFLAGS to avoid
trouble when ALL_CFLAGS changes.
The pattern only applies to one file (ppc/sha1ppc.S) and that
file does not use any #ifdefs, so leaving the dependency out is
probably harmless. Nevertheless, it is safer to include the
dependency in case future code's behavior does depend on the
build flags.

When the ancestor used to have a blob "P", your tree removed it, and the
tree you are merging with also removed it, the agressive three-way cleanly
merges to remove that blob. If the other tree added a new blob "P/Q"
while removing "P", it should also merge cleanly to remove "P" and create
"P/Q" (since neither the ancestor nor your tree could have had it, so it
is a typical "created in one").
The "aggressive" rule is not new anymore. Reword the stale comment.
traverse_trees() is supposed to call its callback with all the matching
entries from the given trees. The current algorithm keeps a pointer to
each of the tree being traversed, and feeds the entry with the earliest
name to the callback.
This breaks down if the trees being traversed looks like this:
A B
t-1 t
t-2 u
t/a v
When we are currently looking at an entry "t-1" in tree A, and tree B has
returned "t", feeding "t" from the B and not feeding anything from A, only
because "t-1" sorts later than "t", will miss an entry for a subtree "t"
behind the current entry in tree A.
This introduces extended_entry_extract() helper function that gives what
name is expected from the tree, and implements a mechanism to look-ahead
in the tree object using it, to make sure such a case is handled sanely.
Traversal in tree A in the above example will first return "t" to match
that of B, and then the next request for an entry to A then returns "t-1".
This roughly corresponds to what Linus's "prepare for one-entry lookahead"
wanted to do, but because this does implement look ahead, t6035 and one more
test in t1012 reveal that the approach would not work without adjusting the
side that walks the index in unpack_trees() as well.
Commit 9e8ecea (Add 'merge' mode to 'git reset', 2008-12-01) disallowed
"git reset --merge" when there was unmerged entries. But it wished if
unmerged entries were reset as if --hard (instead of --merge) has been
used. This makes sense because all "mergy" operations makes sure that
any path involved in the merge does not have local modifications before
starting, so resetting such a path away won't lose any information.
The previous commit changed the behavior of --merge to accept resetting
unmerged entries if they are reset to a different state than HEAD, but it
did not reset the changes in the work tree, leaving the conflict markers
in the resulting file in the work tree.
Fix it by doing three things:
- Update the documentation to match the wish of original "reset --merge"
better, namely, "An unmerged entry is a sign that the path didn't have
any local modification and can be safely resetted to whatever the new
HEAD records";
- Update read_index_unmerged(), which reads the index file into the cache
while dropping any higher-stage entries down to stage #0, not to copy
the object name from the higher stage entry. The code used to take the
object name from the a stage entry ("base" if you happened to have
stage #1, or "ours" if both sides added, etc.), which essentially meant
that you are getting random results depending on what the merge did.
The _only_ reason we want to keep a previously unmerged entry in the
index at stage #0 is so that we don't forget the fact that we have
corresponding file in the work tree in order to be able to remove it
when the tree we are resetting to does not have the path. In order to
differentiate such an entry from ordinary cache entry, the cache entry
added by read_index_unmerged() is marked as CE_CONFLICTED.
- Update merged_entry() and deleted_entry() so that they pay attention to
cache entries marked as CE_CONFLICTED. They are previously unmerged
entries, and the files in the work tree that correspond to them are
resetted away by oneway_merge() to the version from the tree we are
resetting to.
reset: use "unpack_trees()" directly instead of "git read-tree"
This patch makes "reset_index_file()" call "unpack_trees()" directly
instead of forking and execing "git read-tree". So the code is more
efficient.
And it's also easier to see which unpack_tree() options will be used,
as we don't need to follow "git read-tree"'s command line parsing
which is quite complex.
As Daniel Barkalow found, there is a difference between this new
version and the old one. The old version gives an error for
"git reset --merge" with unmerged entries, and the new version does
not when we reset the entries to some states that differ from HEAD.
Instead, it resets the index entry and succeeds, while leaving the
conflict markers in the corresponding file in the work tree (which
will be corrected by the next patch).

CVS Server: Support reading base and roots from environment
The Gitosis single-account Git/ssh hosting system runs git commands
through git-shell after confirming that the connecting user is
authorized to access the requested repository. This works well for
upload-pack and receive-pack, which take a repository argument through
git-shell. This doesn't work so well for `cvs server', which is passed
through literally, with no arguments. Allowing arguments risks
sneaking in `--export-all', so that restriction should be maintained.
Despite that, passing a repository root is necessary for per-user
access control by the hosting software, and passing a base path
improves usability without weakening security. Thus, git-cvsserver
needs to come up with these values at runtime by some other
means. Since git-shell preserves the environment for other purposes,
the environment can carry these arguments as well.
Thus, modify git-cvsserver to read $GIT_CVSSERVER_{BASE_PATH,ROOT} in
the absence of equivalent command line arguments.

reset: improve mixed reset error message when in a bare repo
When running a "git reset --mixed" in a bare repository, the
message displayed is something like:
fatal: This operation must be run in a work tree
fatal: Could not reset index file to revision 'HEAD^'.
This message is a little bit misleading because a mixed reset is
ok in a git directory, so it is not absolutely needed to run it in
a work tree.
So this patch improves upon the above by changing the message to:
fatal: mixed reset is not allowed in a bare repository
And if "git reset" is ever sped up by using unpack_tree() directly
(instead of execing "git read-tree"), this patch will also make
sure that a mixed reset is still disallowed in a bare repository.

Commit 952dfc6 tried to tighten the safety valves for doing
a "reset --hard" in a bare repository or outside the work

This patch unbreaks it.
Most git commands which need a work tree simply use
NEED_WORK_TREE in git.c to die before they get to their
cmd_* function. Reset, however, only needs a work tree in
some cases, and so must handle the work tree itself. The
error that 952dfc6 made was to simply forbid certain
operations if the work tree was not set up; instead, we need
to do the same thing that NEED_WORK_TREE does, which is to
call setup_work_tree(). We no longer have to worry about dying
in the non-worktree case, as setup_work_tree handles that
for us.

Input to "grep" is supposed to be "text", but we deliberately feed output

resolve-undo: teach "update-index --unresolve" to use resolve-undo info
The update-index plumbing command had a hacky --unresolve implementation
that was written back in the days when merge was the only way for users to
end up with higher stages in the index, and assumed that stage #2 must
have come from HEAD, stage #3 from MERGE_HEAD and didn't bother to compute
the stage #1 information.
There were several issues with this approach:
- These days, merge is not the only command, and conflicts coming from
commands like cherry-pick, "am -3", etc. cannot be recreated by looking
at MERGE_HEAD;
- For a conflict that came from a merge that had renames, picking up the
same path from MERGE_HEAD and HEAD wouldn't help recreating it, either;
- It may have been Ok not to recreate stage #1 back when it was written,
because "diff --ours/--theirs" were the only availble ways to review
conflicts and they don't need stage #1 information. "diff --cc" that
was invented much later is a lot more useful way but it needs stage #1.
We can use resolve-undo information recorded in the index extension to
solve all of these issues.
resolve-undo: "checkout -m path" uses resolve-undo information
Once you resolved conflicts by "git add path", you cannot recreate the
conflicted state with "git checkout -m path", because you lost information
from higher stages in the index when you resolved them.
Since we record the necessary information in the resolve-undo index
extension these days, we can reproduce the unmerged state in the index and
check it out.
resolve-undo: allow plumbing to clear the information
At the Porcelain level, operations such as merge that populate an
initially cleanly merged index with conflicted entries clear the
resolve-undo information upfront. Give scripted Porcelains a way
to do the same, by implementing "update-index --clear-resolve-info".
With this, a scripted Porcelain may "update-index --clear-resolve-info"
first and repeatedly run "update-index --cacheinfo" to stuff unmerged
entries to the index, to be resolved by the user with "git add" and
stuff.
Make sure that resolving a failed merge with git add records
the conflicted state, committing the result keeps that state,
and checking out another commit clears the state.
"git ls-files" learns a new option --resolve-undo to show the
recorded information.
resolve-undo: record resolved conflicts in a new index extension section
When resolving a conflict using "git add" to create a stage #0 entry, or
"git rm" to remove entries at higher stages, remove_index_entry_at()
function is eventually called to remove unmerged (i.e. higher stage)
entries from the index. Introduce a "resolve_undo_info" structure and
keep track of the removed cache entries, and save it in a new index
extension section in the index_state.
Operations like "read-tree -m", "merge", "checkout [-m] <branch>" and
"reset" are signs that recorded information in the index is no longer
necessary. The data is removed from the index extension when operations
start; they may leave conflicted entries in the index, and later user
actions like "git add" will record their conflicted states afresh.
Instead of using the low-level index_state interface, use the bog standard
active_cache and active_nr macros to access the cache entries when using the
default one.

As shown, git-svn has some problems; not all svn merges are correctly
detected, and cherry picks may incorrectly be detected as real merges.
These test cases will be marked as _success once the relevant fixes are in.

git svn: fix --revision when fetching deleted paths
When using the -r/--revision argument to fetch deleted history,
calling SVN::Ra::get_log() from an SVN::Ra object initialized
to track the deleted URL will fail.
We now ignore errors from SVN::Ra::get_log() here because using
--revision will always override the value of $head here if
(and only if) we're tracking deleted directories.

rebase -i: abort cleanly if the editor fails to launch

rebase -i: abort cleanly if the editor fails to launch
If the user's configured editor is emacsclient, the editor
will fail to launch if emacs is not running and the git
command that tried to lanuch the editor will abort. For most
commands, all you have to do is to start emacs and repeat
the command.
The "git rebase -i" command, however, aborts without cleaning
the "$GIT_DIR/rebase-merge" directory if it fails to launch the
editor, so you'll need to do "git rebase --abort" before
repeating the rebase command.
Change "git rebase -i" to terminate using "die_abort" (instead of
with "die") if the initial launch of the editor fails.
