In many scripted Porcelain commands, we find this idiom:
if test "$(git rev-parse --verify A)" = "$(git merge-base A B)"
then
... A is an ancestor of B ...
fi
But you do not have to compute exact merge-base only to see if A is
an ancestor of B. Give them a more direct way to use the underlying
machinery.

When 'git log' is passed the --no-walk option, no revision walk takes
place, naturally. Perhaps somewhat surprisingly, however, the provided
revisions still get sorted by commit date. So e.g 'git log --no-walk
HEAD HEAD~1' and 'git log --no-walk HEAD~1 HEAD' give the same result
(unless the two revisions share the commit date, in which case they
will retain the order given on the command line). As the commit that
introduced --no-walk (8e64006 (Teach revision machinery about
--no-walk, 2007-07-24)) points out, the sorting is intentional, to
allow things like
git log --abbrev-commit --pretty=oneline --decorate --all --no-walk
to show all refs in order by commit date.
But there are also other cases where the sorting is not wanted, such
as
<command producing revisions in order> |
git log --oneline --no-walk --stdin
To accomodate both cases, leave the decision of whether or not to sort
up to the caller, by allowing --no-walk={sorted,unsorted}, defaulting
to 'sorted' for backward-compatibility reasons.

Branch names are usually in ASCII so they are not the problem. The
problem most likely comes from "(no branch)" translation, which is
in UTF-8 and makes display-width calculation just wrong. Clarify
this by renaming the field "len" in struct ref_item to "width", as
it stores the display-width and is used to compute the width of the
screen needed to show the names of all the branches, and compute the
display width using utf8_strwidth(), not byte-length with strlen().
Update document to mention the fact that we may want ref names in
UTF-8. Encodings that produce invalid UTF-8 are safe as utf8_strwidth()
falls back to strlen(). The ones that incidentally produce valid UTF-8
sequences will cause misalignment.

Either end of revision range operator can be omitted to default to HEAD,
as in "origin.." (what did I do since I forked) or "..origin" (what did
they do since I forked). But the current parser interprets ".." as an
empty range "HEAD..HEAD", and worse yet, because ".." does exist on the
filesystem, we get this annoying output:
$ cd Documentation/howto
$ git log .. ;# give me recent commits that touch Documentation/ area.
fatal: ambiguous argument '..': both revision and filename
Use '--' to separate filenames from revisions
Surely we could say "git log ../" or even "git log -- .." to disambiguate,
but we shouldn't have to.

The existing --set-uptream option can cause confusion, as it uses the
usual branch convention of assuming a starting point of HEAD if none
is specified, causing
git branch --set-upstream origin/master
to create a new local branch 'origin/master' that tracks the current
branch. As --set-upstream already exists, we can't simply change its
behaviour. To work around this, introduce --set-upstream-to which
accepts a compulsory argument indicating what the new upstream branch
should be and one optinal argument indicating which branch to change,
defaulting to HEAD.
The new options allows us to type
git branch --set-upstream-to origin/master
to set the current branch's upstream to be origin's master.

The --access-hook option to "git daemon" specifies an external
command to be run every time a client connects, with
- service name (e.g. "upload-pack", etc.),
- path to the repository,
- hostname (%H),
- canonical hostname (%CH),
- ip address (%IP),
- tcp port (%P)
as its command line arguments. The external command can decide to
decline the service by exiting with a non-zero status (or to allow it
by exiting with a zero status). It can also look at the $REMOTE_ADDR
and $REMOTE_PORT environment variables to learn about the requestor
when making this decision.
The external command can optionally write a single line to its
standard output to be sent to the requestor as an error message when
it declines the service.

The current code tries to get a list of documented commands
by doing "ls Documentation/git*txt" and culling a bunch of
special cases from the result. Looking for "git-*.txt" would
be more accurate, but would miss a few commands like
"gitweb" and "gitk".
Fortunately, Documentation/Makefile already knows what this
list is, so we can just ask it. Annoyingly, we still have to
post-process its output a little, since make will print
extra cruft like "GIT-VERSION-FILE is up to date" to stdout.
Now that our list is accurate, we can remove all of the ugly
special-cases.

While we're at it, let's capitalize the first letter of
their one-line summaries to match the rest of the git
manpages.
The credential-cache--daemon command is somewhat special. It
is already ignored by check-docs because it contains a "--",
marking it as a non-interesting implementation detail. It
is, in fact, documented, but since the documentation
basically just redirects you to a more appropriate command
anyway, let's explicitly omit it so it is not mentioned in

When asciidoc converts a listing block like:
----------------------
$ git log --merge
----------------------
it marks it to be displayed in a monospace font. This works
fine when generating HTML output. However, when generating
docbook output, we override the expansion of a listingblock
to work around bugs in some versions of the docbook
toolchain. Our override did not mark the listingblock with
the "monospaced" class.
The main output that uses docbook as an intermediate format
is the manpages. We didn't notice any issue there because
the monospaced class seems to be ignored when generating
roff from the docbook manpages.
However, when generating texinfo to make info pages, docbook
does respect this class. The resulting texinfo output
properly uses "@example" blocks to display the listing in
this case. Besides possibly looking prettier in some texinfo
backends, one important effect is that the monospace font
suppresses texinfo's expansion of "--" and "---" into
en-dashes and em-dashes. With the current code, the example
above ends up looking like "git log -merge", which is
confusing and wrong.

The grep.extendedRegexp configuration setting enables the -E flag on grep

Rather than adding an additional setting for grep.fooRegexp for current

can accept appropriate values for modifying the default grep pattern
matching behavior. The current values are "basic", "extended", "fixed",
"perl" and "default" for setting -G, -E, -F, -P and the default behavior
respectively.
When grep.patternType is set to a value other than "default", the
grep.extendedRegexp setting is ignored. The value of "default" restores
the current default behavior, including the grep.extendedRegexp
behavior.
