When we send a value to store_write_pair(), make sure that the value
that gets read out matches the one passed in. This means that for any
value that contains leading or trailing whitespace or any comment
character (# and ;), we need to surround it in quotes.

We have a number of badly checked write() calls. Often we are
expecting write() to write exactly the size we requested or fail,
this fails to handle interrupts or short writes. Switch to using
the new write_in_full(). Otherwise we at a minimum need to check
for EINTR and EAGAIN, where this is appropriate use xwrite().
Note, the changes to config handling are much larger and handled
in the next patch in the sequence.

We recently introduced a write_in_full() which would either write
the specified object or emit an error message and fail. In order
to fix the read side we now want to introduce a read_in_full()
but without an error emit. This patch cleans up the naming
of this family of calls:
1) convert the existing write_or_whine() to write_or_whine_pipe()
to better indicate its pipe specific nature,
2) convert the existing write_in_full() calls to write_or_whine()
to better indicate its nature,
3) introduce a write_in_full() providing a write or fail semantic,
and
4) convert write_or_whine() and write_or_whine_pipe() to use
write_in_full().

With this patch, cvsimport will skip commits made
in the last 10 minutes. The recent-ness test is of
5 minutes + cvsps fuzz window (5 minutes default).
When working with a CVS repository that is in use,
importing commits that are too recent can lead to
partially incorrect trees. This is mainly due to
- Commits that are within the cvsps fuzz window may later
be found to have affected more files.
- When performing incremental imports, clock drift between
the systems may lead to skipped commits.
This commit helps keep incremental imports of in-use
CVS repositories sane.

This updates the way diffcore represents an unmerged pair
somewhat. It used to be that entries with mode=0 on both sides
were used to represent an unmerged pair, but now it has an
explicit flag. This is to allow diff-index --cached to report
the entry from the tree when the path is unmerged in the index.
This is used in updating "git reset <tree> -- <path>" to restore
absense of the path in the index from the tree.

Since we use the reachability tracking machinery now, we should
keep the already checked trees and commits whose completeness is
known, to avoid checking the same thing over and over again.
Signed-off-by: Junio C Hamano <junkio@cox.net>
The logic in an earlier round to detect reflog entries that
point at a broken commit was not sufficient. Just like we do
not trust presense of a commit during pack transfer (we trust
only our refs), we should not trust a commit's presense, even if
the tree of that commit is complete.
A repository that had reflog enabled on some of the refs that
was rewound and then run git-repack or git-prune from older
versions of git can have reflog entries that point at a commit
that still exist but lack commits (or trees and blobs needed for
that commit) between it and some commit that is reachable from
one of the refs.
This revamps the logic -- the definition of "broken commit"
becomes: a commit that is not reachable from any of the refs and
there is a missing object among the commit, tree, or blob
objects reachable from it that is not reachable from any of the
refs. Entries in the reflog that refer to such a commit are
expired.
Since this computation involves traversing all the reachable
objects, i.e. it has the same cost as 'git prune', it is enabled
only when a new option --fix-stale. Fortunately, once this is
run, we should not have to ever worry about missing objects,
because the current prune and pack-objects know about reflogs
and protect objects referred by them.
Unfortunately, this will be absolutely necessary to help people
migrate to the newer prune and repack.

This moves major part of builtin-prune into a separate file,
reachable.c. It is used to mark the objects that are reachable
from refs, and optionally from reflogs.
The patch looks very large, but if you look at it with diff -C,
which this message is formatted in, most of them are copied
lines and there are very little additions.

I want to make the first part of 'git prune' that marks the

first step toward the goal by making the callchain to pass
