When a conflicting file contains a line that begin with "=======", rerere
failed to parse conflict markers. This result to a wrong preimage file and
an unexpected error for the user. The boundary between ours and theirs
not just begin with 7 equals, but is followed by either a SP or a LF.
This patch enforces parsing rules so that markers match in the right order,
and when ambiguous, the command does not autoresolve the conflicted file.
Especially because we are introducing rerere.autoupdate configuration
(which is off by default for safety) that automatically stages the
resolution made by rerere, it is necessary to make sure that we do not
autoresolve when there is any ambiguity.

7ebd52a (Merge branch 'dz/apply-again', 2008-07-01) taught "git-apply" to
grok a (non-git) patch that is a concatenation of separate patches that
touch the same file number of times, by recording the postimage of patch
application of previous round and using it as the preimage for later
rounds.
This "incremental" mode of patch application fundamentally contradicts
with the way git rename/copy patches are designed. When a git patch talks
about a file A getting modified, and a new file B created out of A, like
this:
diff --git a/A b/A
--- a/A
+++ b/A
... change text here ...
diff --git a/A b/B
copy from A
copy to B
--- a/A
+++ b/B
... change text here ...
the second change to produce B does not depend on what is done to A with
the first change in any way. This is explicitly done so for reviewability
of individual patches.
With this commit, we do not look at 'fn_table' that records the postimage
of previous round when applying a patch to produce a new file out of an
existing file.

When the user specifies a ref by a reflog entry older than
one we have (e.g., "HEAD@{20 years ago"}), we issue a
warning and give them the "from" value of the oldest reflog
entry. That is, we say "we don't know what happened before
this entry, but before this we know we had some particular
SHA1".
However, the oldest reflog entry is often a creation event
such as clone or branch creation. In this case, the entry
claims that the ref went from "00000..." (the null sha1) to
the new value, and the reflog lookup returns the null sha1.
While this is technically correct (the entry tells us that
the ref didn't exist at the specified time) it is not
terribly useful to the end user. What they probably want
instead is "the oldest useful sha1 that this ref ever had".
This patch changes the behavior such that if the oldest ref
would return the null sha1, it instead returns the first
value the ref ever had.
We never discovered this problem in the test scripts because
we created "fake" reflogs that had only a specified segment
of history. This patch updates the tests with a creation
event at the beginning of history.

If git attempts to delete a ref, but the unlink of the ref
file fails, we print a message to stderr. This is usually a
good thing, but if the error is ENOENT, then it indicates
that the ref has _already_ been deleted. And since that's
our goal, it doesn't make sense to complain to the user.
This harmonizes the error reporting behavior for the
unpacked and packed cases; the packed case already printed
nothing on ENOENT, but the unpacked printed unconditionally.
Additionally, send-pack would, when deleting the tracking
ref corresponding to a remote delete, print "Failed to
delete" on any failure. This can be a misleading
message, since we actually _did_ delete at the remote side,
but we failed to delete locally. Rather than make the
message more precise, let's just eliminate it entirely; the
delete_ref routine already takes care of printing out a much
more specific message about what went wrong.

When working with a lot of people who backport patches all day long, every
once in a while I get a patch that modifies the same file more than once
inside the same patch. git-apply either fails if the second change relies
on the first change or silently drops the first change if the second change
is independent.
The silent part is the scary scenario for us. Also this behaviour is
different from the patch-utils.
I have modified git-apply to create a table of the filenames of files it
modifies such that if a later patch chunk modifies a file in the table it
will buffer the previously changed file instead of reading the original file
from disk.
Logic has been put in to handle creations/deletions/renames/copies. All the
relevant tests of git-apply succeed.
A new test has been added to cover the cases I addressed.
The fix is relatively straight-forward.

Resetting a selected set of index entries is done with
"git reset -- paths" syntax, but we did not allow -- to be omitted
even when the command is unambiguous.
This updates the command to follow the general rule:
* When -- appears, revs come before it, and paths come after it;
* When there is no --, earlier ones are revs and the rest are paths, and
we need to guess. When lack of -- marker forces us to guess, we
protect from user errors and typoes by making sure what we treat as
revs do not appear as filenames in the work tree, and what we treat as
paths do appear as filenames in the work tree, and by erroring out if
that is not the case. We tell the user to disambiguate by using -- in
such a case.
which is employed elsewhere in the system.
When this rule is applied to "reset", because we can have only zero or one
rev to the command, the check can be slightly simpler than other programs.
We have to check only the first one or two tokens after the command name
and options, and when they are:
-- A:
no explicit rev given; "A" and whatever follows it are paths.
A --:
explicit rev "A" given and whatever follows the "--" are paths.
A B:
"A" could be rev or path and we need to guess. "B" could
be missing but if exists that (and everything that follows) would
be paths.
So we apply the guess only in the last case and only to "A" (not "B" and
what comes after it).
* As long as "A" is unambiguously a path, index entries for "A", "B" (and
everything that follows) are reset to the HEAD revision.
* If "A" is unambiguously a rev, on the other hand, the index entries for
"B" (and everything that follows) are reset to the "A" revision.

The shell version used to use "mkdir -p" to create the repo
path, but the C version just calls "mkdir". Let's replicate
the old behavior. We have to create the git and worktree
leading dirs separately; while most of the time, the
worktree dir contains the git dir (as .git), the user can
override this using GIT_WORK_TREE.
We can reuse safe_create_leading_directories, but we need to
make a copy of our const buffer to do so. Since
merge-recursive uses the same pattern, we can factor this
out into a global function. This has two other cleanup
advantages for merge-recursive:
1. mkdir_p wasn't a very good name. "mkdir -p foo/bar" actually
creates bar, but this function just creates the leading
directories.
2. mkdir_p took a mode argument, but it was completely
ignored.
