This script creates two separate histories, A and B, each of
which does:
(A0, B0): create fileA and subdir/fileB
(A1, B1): modify fileA
(A2, B2): modify subdir/fileB
and then grafts them together to make B0 a child of A2. So
the final history looks like (time flows from top to bottom):
true parent touches subdir?
A0 none yes (creates it)
A1 A0 no
A2 A1 yes
B0 none yes (different from what's in A2)
B1 B0 no
B2 B1 yes
"git rev-list --parents --pretty=raw B2" would give "fake"
parents on the "commit " header lines while "parent " header
lines show the parent as recorded in the commit object (i.e. B0
appears to have A2 as its parent on "commit " header but there
is no "parent A2" header line in it).
When you have path limiters, we simplify history to omit
commits that do not affect the specified paths.
So "git rev-list --parents --pretty=raw B2 subdir" would return
"B2 B0 A2 A0" (because B1 and A1 do not touch the path). When
it does so, the "commit " header lines have "fake" parents
(i.e. B2 appears to have B0 as its parent on "commit " header),
but you can still get the true parents by looking at "parent "
header.

If the user has configured core.filemode=0 then we shouldn't set
the execute bit in the index when adding a new file as the user
has indicated that the local filesystem can't be trusted.
This means that when adding files that should be marked executable
in a repository with core.filemode=0 the user must perform a
'git update-index --chmod=+x' on the file before committing the
addition.

In "git-apply", we have a few sanity checks and heuristics that
expects that the patch fed to us is a unified diff with at least
one line of context.
* When there is no leading context line in a hunk, the hunk
must apply at the beginning of the preimage. Similarly, no
trailing context means that the hunk is anchored at the end.
* We learn a patch deletes the file from a hunk that has no
resulting line (i.e. all lines are prefixed with '-') if it
has not otherwise been known if the patch deletes the file.
Similarly, no old line means the file is being created.
And we declare an error condition when the file created by a
creation patch already exists, and/or when a deletion patch
still leaves content in the file.
These sanity checks are good safety measures, but breaks down
when people feed a diff generated with --unified=0. This was
recently noticed first by Matthew Wilcox and Gerrit Pape.
This adds a new flag, --unified-zero, to allow bypassing these
checks. If you are in control of the patch generation process,
you should not use --unified=0 patch and fix it up with this
flag; rather you should try work with a patch with context. But
if all you have to work with is a patch without context, this
flag may come handy as the last resort.

If GIT_TRACE is set to an absolute path (starting with a
'/' character), we interpret this as a file path and we
trace into it.
Also if GIT_TRACE is set to an integer value greater than
1 and lower than 10, we interpret this as an open fd value
and we trace into it.
Note that this behavior is not compatible with the
previous one.
We also trace whole messages using one write(2) call to
make sure messages from processes do net get mixed up in
the middle.
This patch makes it possible to get trace information when
running "make test".

The intention of the test seems to be to build a long chain of
clones that locally borrow objects from their parents and see the
system give up dereferencing long chains. There were two problems:
(1) it did not test the right repository;
(2) it did not build a chain long enough to trigger the limitation.
I do not think it is a good test to make sure the limitation the
current implementation happens to have still exists, but that is
a topic at a totally different level.
At least this fixes the broken test.

We used to find the first match of the pattern and then if the
match is not for the entire word, declared that the whole line
does not match.
But that is wrong. The command "git grep -w -e mmap" should
find that a line "foo_mmap bar mmap baz" matches, by tring the
second instance of pattern "mmap" on the same line.

The cmd_usage() routine was causing warning messages due to a NULL
format parameter being passed in three out of four calls. This is a
problem if you want to compile with -Werror. A simple solution is to
simply remove the GNU __attribute__ format pragma from the cmd_usage()
declaration in the header file. The function interface was somewhat
muddled anyway, so re-write the code to finesse the problem.
[jc: this incidentally revealed that t9100 test assumed that the output

"Usage" to "usage". Update the test not to rely on "git help" output.]

These changes were originally part of the next patch, but have been
split out since they were peripheral to the main purpose of that patch.
- update comment describing the signature format to reflect
the current code.
- remove trailing \n in calls to error(), since a \n is already
provided by error().
- remove redundant call to get_sha1_hex().
- call sha1_to_hex(sha1) to convert to ascii, rather than attempting
to print the raw sha1.

to git-mktag in this and the next patch.

Alex Riesen (raa.lkml@gmail.com) recently observed that git branch
would fail with no error message due to unexpected situations with
regards to refs. For example, if .git/refs/heads/gu is a file but
"git branch -b refs/heads/gu/fixa HEAD" was invoked by the user
it would fail silently due to refs/heads/gu being a file and not
a directory.
This change adds a test for trying to create a ref within a directory
that is actually currently a file, and adds error printing within
the ref locking routine should the resolve operation fail.
The error printing code probably belongs at this level of the library
as other failures within the ref locking, writing and logging code
are also currently at this level of the code.

Linus:
get_pathspec() does turn '.' into an empty string (which is
correct - git internally does _not_ ever understand the notion of
"." as the current working directory), but it doesn't ever do the
optimization of noticing that a pathspec that consists solely of
an empty string is "equivalent" to an empty pathspec.
The test is to ensure that this behaviour stays.

I've found that git apply is incapable of handling patches
involving object type changes to the same path.
Of course git itself is perfectly capable of making commits that
generate these changes, as it only tracks trees states. It's
just that the diffs between them are less useful if they can't
be applied.
Some of these are rare, but I've hit one of them (file becoming
a symlink) recently in real-world usage, and was inspired to
find more potential breakages :)
I'm not sure when I'll have time to fix these myself and I'm not
very familiar with the apply code. So if someone could get
some or all of these cases working, they would be my hero :)
Some of these are what I would refer to as corner-cases from
hell. Most (if not all) other systems fail some of these. In
fact, they aren't even capable of representing most of these
changes in their histories; much less being able to handle
patches to that effect.

If committing a merge (.git/MERGE_HEAD exists), an initial tree
(no HEAD) or using --amend to amend the prior commit then denote
the subtype of commit in the reflog. This helps to distinguish
amended or merge commits from normal commits.
In the case of --amend the prior sha1 is probably the commit which
is being thrown away in favor of the new commit. Since it is likely
that the old commit doesn't have any ref pointing to it anymore
it can be interesting to know why that the commit was replaced
and orphaned.
In the case of a merge the prior sha1 is probably the first parent
of the new merge commit. Consequently having its prior sha1 in the
reflog is slightly less interesting but its still informative to
know the commit was the result of a merge which had to be completed
by hand.
