Junio C Hamano 01754769ab Don't force everybody to call setup_ident().
Back when only handful commands that created commit and tag were
the only users of committer identity information, it made sense
to explicitly call setup_ident() to pre-fill the default value
from the gecos information.  But it is much simpler for programs
to make the call automatic when get_ident() is called these days,
since many more programs want to use the information when updating
the reflog.

Junio C Hamano cb280e1075 Allow non-developer to clone, checkout and fetch more easily.
The code that uses committer_info() in reflog can barf and die
whenever it is asked to update a ref.  And I do not think
calling ignore_missing_committer_name() upfront like recent
receive-pack did in the aplication is a reasonable workaround.

What the patch does.

 - git_committer_info() takes one parameter.  It used to be "if
   this is true, then die() if the name is not available due to
   bad GECOS, otherwise issue a warning once but leave the name
   empty".  The reason was because we wanted to prevent bad
   commits from being made by git-commit-tree (and its
   callers).  The value 0 is only used by "git var -l".

   Now it takes -1, 0 or 1.  When set to -1, it does not
   complain but uses the pw->pw_name when name is not
   available.  Existing 0 and 1 values mean the same thing as
   they used to mean before.  0 means issue warnings and leave
   it empty, 1 means barf and die.

 - ignore_missing_committer_name() and its existing caller
   (receive-pack, to set the reflog) have been removed.

 - git-format-patch, to come up with the phoney message ID when
   asked to thread, now passes -1 to git_committer_info().  This
   codepath uses only the e-mail part, ignoring the name.  It
   used to barf and die.  The other call in the same program
   when asked to add signed-off-by line based on committer
   identity still passes 1 to make sure it barfs instead of
   adding a bogus s-o-b line.

 - log_ref_write in refs.c, to come up with the name to record
   who initiated the ref update in the reflog, passes -1.  It
   used to barf and die.

The last change means that git-update-ref, git-branch, and
commit walker backends can now be used in a repository with
reflog by somebody who does not have the user identity required
to make a commit.  They all used to barf and die.

I've run tests and all of them seem to pass, and also tried "git
clone" as a user whose GECOS is empty -- git clone works again
now (it was broken when reflog was enabled by default).

But this definitely needs extra sets of eyeballs.

Jeff King 90f70a910a format-patch: fix bug with --stdout in a subdirectory
We set the output directory to the git subdirectory prefix if one has
not already been specified. However, in the case of --stdout, we
explicitly _don't_ want the output directory to be set. The result was
that "git-format-patch --stdout" in a directory besides the project root
produced the "standard output, or directory, which one?" error message.

Junio C Hamano d2c11a38c4 UTF-8: introduce i18n.logoutputencoding.
It is plausible for somebody to want to view the commit log in a
different encoding from i18n.commitencoding -- the project's
policy may be UTF-8 and the user may be using a commit message
hook to run iconv to conform to that policy (and either not have
i18n.commitencoding to default to UTF-8 or have it explicitly
set to UTF-8).  Even then, Latin-1 may be more convenient for
the usual pager and the terminal the user uses.

The new variable i18n.logoutputencoding is used in preference to
i18n.commitencoding to decide what encoding to recode the log
output in when git-log and friends formats the commit log message.

Junio C Hamano 52883fbd76 Teach log family --encoding
Updated commit objects record the encoding used in their
encoding header.  This updates the log family to reencode it
into the encoding specified in i18n.commitencoding (or the
default, which is "utf-8") upon output.

To force a specific encoding that is different, log family takes
command line flag --encoding=<encoding>; giving --encoding=none
entirely disables the reencoding and lets you view log messges
in their original encoding.

 (3) system headers that are included in "git-compat-util.h"

 (4) "git-compat-util.h" does not have to include subsystem
     specific header files (e.g. expat.h).

Andy Parkins a159ca0cb7 Allow subcommand.color and color.subcommand color configuration
While adding colour to the branch command it was pointed out that a
config option like "branch.color" conflicts with the pre-existing
"branch.something" namespace used for specifying default merge urls and
branches.  The suggested solution was to flip the order of the
components to "color.branch", which I did for colourising branch.

This patch does the same thing for
  - git-log (color.diff)
  - git-status (color.status)
  - git-diff (color.diff)
  - pager (color.pager)

I haven't removed the old config options; but they should probably be
deprecated and eventually removed to prevent future namespace
collisions.  I've done this deprecation by changing the documentation
for the config file to match the new names; and adding the "color.XXX"
options to contrib/completion/git-completion.bash.

Unfortunately git-svn reads "diff.color" and "pager.color"; which I
don't like to change unilaterally.

Rene Scharfe 2b60356da5 Make git-cherry handle root trees
This patch on top of 'next' makes built-in git-cherry handle root
commits.

It moves the static function log-tree.c::diff_root_tree() to
tree-diff.c and makes it more similar to diff_tree_sha1() by
shuffling around arguments and factoring out the call to
log_tree_diff_flush().  Consequently the name is changed to
diff_root_tree_sha1().  It is a version of diff_tree_sha1() that
compares the empty tree (= root tree) against a single 'real' tree.

This function is then used in get_patch_id() to compute patch IDs
for initial commits instead of SEGFAULTing, as the current code
does if confronted with parentless commits.

Linus Torvalds db6296a566 Call setup_git_directory() early
Any git command that expects to work in a subdirectory of a project, and
that reads the git config files (which is just about all of them) needs to
make sure that it does the "setup_git_directory()" call before it tries to
read the config file.

This means, among other things, that we need to move the call out of
"init_revisions()", and into the caller.

This does the mostly trivial conversion to do that.

Junio C Hamano ef1d9c5aa4 log and diff family: honor config even from subdirectories
There currently is an unfortunate circular dependency between
what init_revisions (the command line revision specification
parser) does and setting up the log and diff options.  The
function uses setup_git_directory() to find the root of the
project relative to the current directory and calls diff_setup()
to prepare diff generation.  However, some of the things that
diff_setup() does needs to depend on the configuration variable,
which needs to be read after setup_git_directory() is called.

This patch is a low impact workaround.  It first lets
init_revisions() to run and do its thing, then uses git_config()
and diff_setup() after it returns, so that configuration
variables that affects the diff operation can be used from
subdirectories.

Junio C Hamano 83ad63cfeb diff: do not use configuration magic at the core-level
The Porcelainish has become so much usable as the UI that there
is not much reason people should be using the core programs by
hand anymore.  At this point we are better off making the
behaviour of the core programs predictable by keeping them
unaffected by the configuration variables.  Otherwise they will
become very hard to use as reliable building blocks.

For example, "git-commit -a" internally uses git-diff-files to
figure out the set of paths that need to be updated in the
index, and we should never allow diff.renames that happens to be
in the configuration to interfere (or slow down the process).

The UI level configuration such as showing renamed diff and
coloring are still honored by the Porcelainish ("git log" family
and "git diff"), but not by the core anymore.

Linus Torvalds 1f1e895fcc Add "named object array" concept
We've had this notion of a "object_list" for a long time, which eventually
grew a "name" member because some users (notably git-rev-list) wanted to
name each object as it is generated.

That object_list is great for some things, but it isn't all that wonderful
for others, and the "name" member is generally not used by everybody.

This patch splits the users of the object_list array up into two: the
traditional list users, who want the list-like format, and who don't
actually use or want the name. And another class of users that really used
the list as an extensible array, and generally wanted to name the objects.

The patch is fairly straightforward, but it's also biggish. Most of it
really just cleans things up: switching the revision parsing and listing
over to the array makes things like the builtin-diff usage much simpler
(we now see exactly how many members the array has, and we don't get the
objects reversed from the order they were on the command line).

One of the main reasons for doing this at all is that the malloc overhead
of the simple object list was actually pretty high, and the array is just
a lot denser. So this patch brings down memory usage by git-rev-list by
just under 3% (on top of all the other memory use optimizations) on the
mozilla archive.

It does add more lines than it removes, and more importantly, it adds a
whole new infrastructure for maintaining lists of objects, but on the
other hand, the new dynamic array code is pretty obvious. The change to
builtin-diff-tree.c shows a fairly good example of why an array interface
is sometimes more natural, and just much simpler for everybody.

Eric W. Biederman 6c4cca1c72 Fix git-format-patch -s
When git-format-patch was converted to a builtin an appropriate call
to setup_ident was missed and thus git-format-patch -s fails because
it doesn't look up anything in the password file.

Linus Torvalds cb115748ec Some more memory leak avoidance
This is really the dregs of my effort to not waste memory in git-rev-list,
and makes barely one percent of a difference in the memory footprint, but
hey, it's also a pretty small patch.

It discards the parent lists and the commit buffer after the commit has
been shown by git-rev-list (and "git log" - which already did the commit
buffer part), and frees the commit list entry that was used by the
revision walker.

The big win would be to get rid of the "refs" pointer in the object
structure (another 5%), because it's only used by fsck. That would require
some pretty major surgery to fsck, though, so I'm timid and did the less
interesting but much easier part instead.

This (percentually) makes a bigger difference to "git log" and friends,
since those are walking _just_ commits, and thus the list entries tend to
be a bigger percentage of the memory use. But the "list all objects" case
does improve too.

Linus Torvalds 9202434cbd gitweb.cgi history not shown
This does:

 - add a "rev.simplify_history" flag which defaults to on
 - it turns it off for "git whatchanged" (which thus now has real
   semantics outside of "git log")
 - it adds a command line flag ("--full-history") to turn it off for
   others (ie you can make "git log" and "gitk" etc get the semantics if
   you want to.

Now, just as an example of _why_ you really really really want to simplify
history by default, apply this patch, install it, and try these two
command lines:

	gitk --full-history -- git.c
	gitk -- git.c

and compare the output.

So with this, you can also now do

	git whatchanged -p -- gitweb.cgi
	git log -p --full-history -- gitweb.cgi

and it will show the old history of gitweb.cgi, even though it's not
relevant to the _current_ state of the name "gitweb.cgi"

NOTE NOTE NOTE! It will still actually simplify away merges that didn't
change anything at all into either child. That creates these bogus strange
discontinuities if you look at it with "gitk" (look at the --full-history
gitk output for git.c, and you'll see a few strange cases).

So the whole "--parent" thing ends up somewhat bogus with --full-history
because of this, but I'm not sure it's worth even worrying about. I don't
think you'd ever want to really use "--full-history" with the graphical
representation, I just give it as an example exactly to show _why_ doing
so would be insane.

I think this is trivial enough and useful enough to be worth merging into
the stable branch.
