Format-patch generates emails with the "From" address set to the
author of each patch. If you are going to send the emails, however,
you would want to replace the author identity with yours (if they
are not the same), and bump the author identity to an in-body
header.
Normally this is handled by git-send-email, which does the
transformation before sending out the emails. However, some
workflows may not use send-email (e.g., imap-send, or a custom
script which feeds the mbox to a non-git MUA). They could each
implement this feature themselves, but getting it right is
non-trivial (one must canonicalize the identities by reversing any
RFC2047 encoding or RFC822 quoting of the headers, which has caused
many bugs in send-email over the years).
This patch takes a different approach: it teaches format-patch a
"--from" option which handles the ident check and in-body header
while it is writing out the email. It's much simpler to do at this
level (because we haven't done any quoting yet), and any workflow
based on format-patch can easily turn it on.

In the current code, callers are expected to fill in the
pretty_print_context, and then the pretty.c functions simply
read from it. This leaves no room for the pretty.c functions
to communicate with each other by manipulating the context
(e.g., data seen while printing the header may impact how we
print the body).
Rather than introduce a new struct to hold modifiable data,
let's just drop the const-ness of the existing context
struct.

Users can set submodule.$name.update to '!command' which will cause
'command' to be run instead of checkout/merge/rebase. This allows
the user finer-grained control over how the update is done.
The primary motivation for this was interoperability with stgit;
however being able to intercept the submodule update process may
prove useful for integrating with or extending other tools.

These three options mean "favor fast-forwarding when possible,
without creating an unnecessary merge", "never fast-forward and
always create a merge commit even when the commit being merged is a
strict descendant", and "we do not want to create any merge commit;
update only when the merged commit is a strict descendant".
They are "pick one out of these three possibilities" options, and
correspond to "merge.ff" configuration that is tri-state (yes, no
and only).
However, the implementation did not follow the usual convention for
the command line options (later one wins, and command line overrides
what is in the configuration).
Fix this by consolidating two variables (fast_forward_only and
allow_fast_forward) used in the implementation into one enum that
can take one of the three possible values.

When we call find_common to start finding common ancestors
with the remote side of a fetch, the first thing we do is
insert the tip of each ref into our rev_list linked list. We
keep the list sorted the whole time with
commit_list_insert_by_date, which means our insertion ends
up doing O(n^2) timestamp comparisons.
We could teach rev_list_push to use an unsorted list, and
then sort it once after we have added each ref. However, in
get_rev, we process the list by popping commits off the
front and adding parents back in timestamp-sorted order. So
that procedure would still operate on the large list.
Instead, we can replace the linked list with a heap-based
priority queue, which can do O(log n) insertion, making the
whole insertion procedure O(n log n).
As a result of switching to the prio_queue struct, we fix
two minor bugs:
1. When we "pop" a commit in get_rev, and when we clear
the rev_list in find_common, we do not take care to
free the "struct commit_list", and just leak its
memory. With the prio_queue implementation, the memory
management is handled for us.
2. In get_rev, we look at the head commit of the list,
possibly push its parents onto the list, and then "pop"
the front of the list off, assuming it is the same
element that we just peeked at. This is typically going
to be the case, but would not be in the face of clock
skew: the parents are inserted by date, and could
potentially be inserted at the head of the list if they
have a timestamp newer than their descendent. In this
case, we would accidentally pop the parent, and never
process it at all.
The new implementation pulls the commit off of the
queue as we examine it, and so does not suffer from
this problem.
With this patch, a fetch of a single commit into a
repository with 50,000 refs went from:
real 0m7.984s
user 0m7.852s
sys 0m0.120s
to:
real 0m2.017s
user 0m1.884s
sys 0m0.124s
Before this patch, a larger case with 370K refs still had
not completed after tens of minutes; with this patch, it
completes in about 12 seconds.

We insert the commit pointed to by each ref one-by-one into
the "complete" commit_list using insert_by_date. Because
each insertion is O(n), we end up with O(n^2) behavior.
This typically doesn't matter, because the number of refs is
reasonably small. And even if there are a lot of refs, they
often point to a smaller set of objects (in which case the
optimization in commit ea5f220 keeps our "n" small).
However, in pathological repositories (hundreds of thousands
of refs, each pointing to a unique commit), this quadratic
behavior can make a difference. Since we do not care about
the list order until we have finished building it, we can
simply keep it unsorted during the insertion phase, then
sort it afterwards.
On a repository like the one described above, this dropped
the time to do a no-op fetch from 2.0s to 1.7s. On normal
repositories, it probably does not matter at all, but it
does not hurt to protect ourselves from pathological cases.

One test in t1512 that expects a failure incorrectly passed. The
test prepares a commit whose object name begins with ten "0"s, and
also prepares a tag that points at the commit. The object name of
the tag also begins with ten "0"s. There is no other commit-ish
object in the repository whose name begins with such a prefix.
Ideally, in such a repository:
$ git rev-parse --verify 0000000000^{commit}
should yield that commit. If 0000000000 is taken as the commit
0000000000e4f, peeling it to a commmit yields that commit itself,
and if 0000000000 is taken as the tag 0000000000f8f, peeling it to a
commit also yields the same commit, so in that twisted sense, the
extended SHA-1 expression 0000000000^{commit} is unambigous. The
test that expects a failure is to check the above command.
The reason the test expects a failure is that we did not implement
such a "unification" of two candidate objects. What we did (or at
least, meant to) implement was to recognise that a commit-ish is
required to expand 0000000000, and notice that there are two succh
commit-ish, and diagnose the request as ambiguous.
However, there was a bug in the logic to check the candidate
objects. When the code saw 0000000000f8f (a tag) that shared the
shortened prefix (ten "0"s), it tried to make sure that the tag is a
commit-ish by looking at the tag object. Because it incorrectly
used lookup_object() when the tag has not been parsed, however, we
incorrectly declared that the tag is _not_ a commit-ish, leaving the
sole commit in the repository, 0000000000e4f, that has the required
prefix as "unique match", causing the test to pass when it shouldn't.
This fixes the logic to inspect the type of the object a tag refers
to, to make the test that is expected to fail correctly fail.

"stash save" is about saving the local change to the working tree,
but also about restoring the state of the last commit to the working
tree. When a local change is to turn a non-directory to a directory,
in order to restore the non-directory, everything in the directory
needs to be removed.
Which is fine when running "git stash save --include-untracked",
but without that option, untracked, newly created files in the
directory will have to be discarded, if the state you are restoring
to has a non-directory at the same path as the directory.
Introduce a safety valve to fail the operation in such case, using
the "ls-files --killed" which was designed for this exact purpose.
The "stash save" is stopped when untracked files need to be
discarded because their leading path ceased to be a directory, and
the user is required to pass --force to really have the data
removed.

When the working tree walker encounters a directory, it asks the
function treat_directory() if it should descend into it, show it as
an untracked directory, or do something else. When the directory is
the top of the submodule working tree, we used to say "That is an
untracked directory", which was bogus.
It is an entity that is tracked in the index of the repository we
are looking at, and that is not to be descended into it. Return
path_none, not path_untracked, to report that.
The existing case that path_untracked is returned for a newly
discovered submodule that is not tracked in the index (this only
happens when DIR_NO_GITLINKS option is not used) is unchanged, but
that is exactly because the submodule is not tracked in the index.
