The --full-history traversal keeps all merges in addition to non-merge
commits that touch paths in the given pathspec. This is useful to view
both sides of a merge in a topology like this:
A---M---o
/ /
---O---B
even when A and B makes identical change to the given paths. The revision
traversal without --full-history aims to come up with the simplest history
to explain the final state of the tree, and one of the side branches can
be pruned away.
The behaviour to keep all merges however is inconvenient if neither A nor
B touches the paths we are interested in. --full-history reduces the
topology to:
---O---M---o
in such a case, without removing M.
This adds a post processing phase on top of --full-history traversal to
remove needless merges from the resulting history.
The idea is to compute, for each commit in the "full history" result set,
the commit that should replace it in the simplified history. The commit
to replace it in the final history is determined as follows:
* In any case, we first figure out the replacement commits of parents of
the commit we are looking at. The commit we are looking at is
rewritten as if the replacement commits of its original parents are its
parents. While doing so, we reduce the redundant parents from the
rewritten parent list by not just removing the identical ones, but also
removing a parent that is an ancestor of another parent.
* After the above parent simplification, if the commit is a root commit,
an UNINTERESTING commit, a merge commit, or modifies the paths we are
interested in, then the replacement commit of the commit is itself. In
other words, such a commit is not dropped from the final result.
The first point above essentially means that the history is rewritten in
the bottom up direction. We can rewrite the parent list of a commit only
after we know how all of its parents are rewritten. This means that the
processing needs to happen on the full history (i.e. after limit_list()).

We used to set the TOPOSORT flag of commits during the topological
sorting, but we can just as well use the member "indegree" for it:
indegree is now incremented by 1 in the cases where the commit used
to have the TOPOSORT flag.
This is the same behavior as before, since indegree could not be
non-zero when TOPOSORT was unset.
Incidentally, this fixes the bug in show-branch where the 8th column
was not shown: show-branch sorts the commits in topological order,
assuming that all the commit flags are available for show-branch's
private matters.
But this was not true: TOPOSORT was identical to the flag corresponding
to the 8th ref. So the flags for the 8th column were unset by the
topological sorting.

A wildcard refspec is internally parsed into a refspec structure with src
and dst strings. Many parts of the code assumed that these do not include
the trailing "/*" when matching the wildcard pattern with an actual ref we
see at the remote. What this meant was that we needed to make sure not
just that the prefix matched, and also that a slash followed the part that
matched.
But a codepath that scans the result from ls-remote and finds matching
refs forgot to check the "matching part must be followed by a slash" rule.
This resulted in "refs/heads/b1" from the remote side to mistakenly match
the source side of "refs/heads/b/*:refs/remotes/b/*" refspec.
Worse, the refspec crafted internally by "git-clone", and a hardcoded
preparsed refspec that is used to implement "git-fetch --tags", violated
this "parsed widcard refspec does not end with slash" rule; simply adding
the "matching part must be followed by a slash" rule then would have
broken codepaths that use these refspecs.
This commit changes the rule to require a trailing slash to parsed
wildcard refspecs. IOW, "refs/heads/b/*:refs/remotes/b/*" is parsed as
src = "refs/heads/b/" and dst = "refs/remotes/b/". This allows us to
simplify the matching logic because we only need to do a prefixcmp() to
notice "refs/heads/b/one" matches and "refs/heads/b1" does not.

If a user passes "--template=", then our template parameter
is blank. Unfortunately, copy_templates() assumes it has at
least one character, and does all sorts of bad things like
reading from template[-1] and then proceeding to link all of
'/' into the .git directory.
This patch just checks for that condition in copy_templates
and aborts. As a side effect, this means that --template=
now has the meaning "don't copy any templates."

Commands which use parse_options() but also call setup_revisions()
must do their parsing in a two step process:
1. first, they parse all options. Anything unknown goes to
parse_revision_opt() (which calls handle_revision_opt), which
may claim the option or say "I don't recognize this"
2. the non-option remainder goes to setup_revisions() to
actually get turned into revisions
Some revision options are "non-options" in that they must be
parsed in order with their revision counterparts in
setup_revisions(). For example, "--all" functions as a
pseudo-option expanding to all refs, and "--no-walk" affects refs
after it on the command line, but not before. The revision option
parser in step 1 recognizes such options and sets them aside for
later parsing by setup_revisions().
However, the return value used from handle_revision_opt indicated
"I didn't recognize this", which was wrong. It did, and it took
appropriate action (even though that action was just deferring it
for later parsing). Thus it should return "yes, I recognized
this."
Previously, these pseudo-options generated an error when used with
parse_options parsers (currently just blame and shortlog). With
this patch, they should work fine, enabling things like "git
shortlog --all".

When merging an early part of a branch, e.g. "git merge xyzzy~20", we were
supposed to say "branch 'xyzzy' (early part)", but it incorrectly said
"branch 'refs/heads/xy' (early part)" instead.
The logic was supposed to first strip away "~20" part to make sure that
what follows "~" is a non-zero posint, prefix it with "refs/heads/" and
ask resolve_ref() if it is a ref. If it is, then we know xyzzy was a
branch, and we can give the correct message.
However, there were a few bugs. First of all, the logic to build this
"true branch refname" did not count the characters correctly. At this
point of the code, "len" is the number of trailing, non-name part of the
given extended SHA-1 expression given by the user, i.e. number of bytes in
"~20" in the above example.
In addition, the message forgot to skip "refs/heads/" it prefixed from the
output.

Suppose you have this topology, and you are trying to make an octopus
across A, B and C (you are at C and merging A and B into your branch).
The protoccol between "git merge" and merge strategies is for the former
to pass common ancestor(s), '--' and then commits being merged.
git-merge-octopus does not produce the final merge in one-go. It
iteratively produces pairwise merges. So the first step might be to come
up with a merge between B and C:
o---o---o---o---C
/ :
/ o---o---o---B..(M)
/ /
---1---2---o---o---o---A
and for that, "1" is used as the merge base, not because it is the base
across A, B and C but because it is the base between B and C. For this
merge, A does not matter.
I drew M in parentheses and lines between B and C to it in dotted line
because we actually do _not_ create a real commit --- the only thing we
need is a tree object, in order to proceed to the next step.
Then the final merge result is obtained by merging tree of (M) and A using
their common ancestor. For that, we _could_ still use "1" as the merge
base.
But if you imagine a case where you started from A and M, you would _not_
pick "1" as the merge base; you would rather use "2" which is a better
base for this merge.
That is why git-merge-octopus ignores the merge base given by "merge" but
computes its own.
The comment at the end of git-merge-octopus talks about "merge reference
commit", that we used to update it to common found in this round, and that
that updating was pointless. After the first round of merge to produce
the tree for M (but without actually creating the commit object M itself),
in order to figure out the merge base used to merge that with A in the
second round, we used to use A and "1" (which was merge base between B and
C). That was pointless --- "merge-base A 1" is guaranteed to give a base
that is no better than either "merge-base A B" or "merge-base A C". So
the current code keeps using the original head (iow, MRC=C, because in
this case we are starting from C and merging B and then A into it).
This trickerly was necessary only because we avoided creating the extra
merge commit object M.
Side note. An alternative implementation could have been to
actually record it as a real merge commit M, and then let the
two-commit merge-base compute the base between A and M when
merging A to the result of the previous round, but we avoided
creating M, at the expense of potentially using suboptimal base in
the later rounds.
But we do not have to be that pessimistic. We can instead accumulate the
commits we have merged so far in MRC, and have merge_bases_many() compute
the merge base for the new head being merged and the heads we have
processed so far, which can give a better base than what we currently do.

The ie_modified() function is the workhorse for refresh_cache_entry(),
i.e. checking if an index entry that is stat-dirty actually has changes.
After running quicker check to compare cached stat information with
results from the latest lstat(2) to answer "has modification" early, the
code goes on to check if there really is a change by comparing the staged
data with what is on the filesystem by asking ce_modified_check_fs().
However, this function always said "no change" for any gitlinks that has a
directory at the corresponding path. This made ie_modified() to miss
actual changes in the subproject.
The patch fixes this first by modifying an existing short-circuit logic
before calling the ce_modified_check_fs() function. It knows that for any
filesystem entity to which ie_match_stat() says its data has changed, if
its cached size is nonzero then the contents cannot match, which is a
correct optimization only for blob objects. We teach gitlink objects to
this special case, as we already know that any gitlink that
ie_match_stat() says is modified is indeed modified at this point in the
codepath.
With the above change, we could leave ce_modified_check_fs() broken, but
it also futureproofs the code by teaching it to use ce_compare_gitlink(),
instead of assuming (incorrectly) that any directory is unchanged.

This patch makes two small changes to improve the output of --inline

The first is to write a newline preceding the boundary. This is needed because
MIME defines the encapsulation boundary as including the preceding CRLF (or in
this case, just LF), so we should be writing one. Without this, the last
newline in the pre-diff content is consumed instead.
The second change is to always write the line termination character
(default: newline) even when using --inline or --attach. This is simply to
improve the aesthetics of the resulting message. When using --inline an email
client should render the resulting message identically to the non-inline
version. And when using --attach this adds a blank line preceding the
