Since commit 8eca0b47ff, it is possible
for read_sha1_file() to return NULL even with existing objects when they
are corrupted. Previously a corrupted object would have terminated the
program immediately, effectively making read_sha1_file() return NULL
only when specified object is not found.
Let's restore this behavior for all users of read_sha1_file() and
provide a separate function with the ability to not terminate when
bad objects are encountered.

This change makes "submodule add" much more strict in the arguments it
takes, and is intended to address confusion as recently noted on the
git-list. With this change, the required syntax is:
$ git submodule add URL path
Specifically, this eliminates the form
$ git submodule add URL
which was confused by more than one person as
$ git submodule add path
With this patch, the URL locating the submodule's origin repository can be
either an absolute URL, or (if it begins with ./ or ../) can express the
submodule's repository location relative to the superproject's origin.
This patch also eliminates a third form of URL, which was relative to the
superproject's top-level directory (not its repository). Any URL that was
neither absolute nor matched ./*|../* was assumed to point to a
subdirectory of the superproject as the location of the submodule's origin
repository. This URL form was confusing and does not seem to correspond
to an important use-case. Specifically, no-one has identified the need to
clone from a repository already in the superproject's tree, but if this is
needed it is easily done using an absolute URL: $(pwd)/relative-path. So,
no functionality is lost with this patch. (t6008-rev-list-submodule.sh did
rely upon this relative URL, fixed by using $(pwd).)
Following this change, there are exactly four variants of
submodule-add, as both arguments have two flavors:
URL can be absolute, or can begin with ./|../ and thus names the
submodule's origin relative to the superproject's origin.
Note: With this patch, "submodule add" discerns an absolute URL as
matching /*|*:*: e.g., URL begins with /, or it contains a :. This works
for all valid URLs, an absolute path in POSIX, as well as an absolute path
on Windows).
path can either already exist as a valid git repo, or will be cloned from
the given URL. The first form here eases creation of a new submodule in
an existing superproject as the submodule can be added and tested in-tree
before pushing to the public repository. However, the more usual form is
the second, where the repo is cloned from the given URL.
This specifically addresses the issue of
$ git submodule add a/b/c
attempting to clone from a repository at "a/b/c" to create a new module
in "c". This also simplifies description of "relative URL" as there is now
exactly *one* form: a URL relative to the parent's origin repo.

find-rev and rebase error out on svm because git-svn doesn't trace the

This fixes Git::SVN::find_by_url to find branches based on the

There are two cases for preserving merges:
1. The merge base is outside the trunk that is to be rebased.
Then commits of those other parents must not be picked.
2. The merge base is inside the trunk that is to be rebased.
Then all the commits related to that merge must be picked
and the merge must be redone.
The "preserve merges with -p" test case tested for case 1 only.
This patch adds case 2.

If you want to reuse the rerere cache in another repository, and set
a symbolic link to it, you do not want to have the two repositories
interfer with each other by accessing the _same_ MERGE_RR.
For example, if you use contrib/git-new-workdir to set up a second
working directory, and you have a conflict in one working directory,
but commit in the other working directory first, the wrong "resolution"
will be recorded.
The easy solution is to move MERGE_RR out of the rr-cache/ directory,
which also corresponds with the notion that rr-cache/ contains cached
resolutions, not some intermediate temporary states.

The test created an initial commit, made .git/objects unwritable and then
exercised various codepaths to create loose commit, tree and blob objects
to make sure the commands notice failures from these attempts.
However, the initial commit was not preceded with test_tick, which made
its object name depend on the timestamp. The names of all the later tree
and blob objects the test tried to create were static. If the initial
commit's object name happened to begin with the same two hexdigits as the
tree or blob objects the test later attempted to create, the fan-out
directory in which these tree or blob would be created is already created
when the initial commit was made, and the object creation succeeds, and
commands being tested should not notice any failure --- in short, the test
was bogus.
This makes the fan-out directories also unwritable, and adds test_tick
before the commit object creation to make the test repeatable.
The contents of the file to create a blob from "a" to "60" is to force the
name of the blob object to begin with "1b", which shares the fan-out
directory with the initial commit that is created with the test. This was
useful when diagnosing the breakage of this test.

06cbe85 (Make core.sharedRepository more generic, 2008-04-16) broke the
traditional setting of core.sharedRepository to true, which was to make
the repository group writable: with umask 022, it would clear the
permission bits for 'other'. (umask 002 did not exhibit this behaviour
since pre-chmod() check in adjust_shared_perm() fails in that case.)
The call to adjust_shared_perm() should only loosen the permission.
If the user has umask like 022 or 002 that allow others to read, the
resulting files should be made readable and writable by group, without
restricting the readability by others.
This patch fixes the adjust_shared_perm() mode tweak based on Junio's
suggestion and adds the appropriate tests to t/t1301-shared-repo.sh.

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.
