Add "--" in the "git rev-list" command line so that if there is a bug
and the revisions cannot be found, the error message is a bit less

555bdc66ea git-svn: Demonstrate a bug with root commits in mergeinfo ranges
If a svn:mergeinfo range starts at a commit that was converted as a
git root commit (e.g., r1 or a branch that was created out of thin
air), then there is an error when git-svn tries to run

    git rev-list "$bottom_commit^..$top_commit"

because $bottom_commit (the git commit corresponding to r1) has no
parent.

5ad6d387f1 git-instaweb: Check that correct config file exists for (re)start
Currently start/restart does not generate any configuration files for
spawning a new instance.  This means that

  $ git instaweb --http=<server> --start

might pick up stale 'httpd.conf' file for a different web server
(e.g. for default lighttpd when requesting apache2).

This commit changes that, and makes git-instaweb generate web server
config file and/or gitweb config file if don't exists.

This required naming config files after the name of web server
(alternate solution would be to somehow mark for which web server was
config file generated).

Note that web servers that embed configuration in server script file,
namely webrick and plackup, and which delete "$conf" in their *_conf
function, would have their config (server script) always regenerated.

Note: this commit introduces a bit of code repetition (but only a few
lines).

c0175f92c7 git-instaweb: Move all actions at the end of script
As a nice side-effect now the order of parameters does not matter:

  $ git instaweb --httpd=apache2 --start

is now (after this patch) the same as

  $ git instaweb --start --httpd=apache2

Before this commit --start, --stop, --restart (and their subcommand
versions start, stop, restart) exited immediately.

This is preparatory work for making start/restart check that correct
configuration is set up; this change was required to have access in
start_httpd to requested web browser etc.

0aceb22097 git-remote.txt: avoid sounding as if loose refs are the only ones in the world
It was correct to say "The file $GIT_DIR/refs/heads/master stores the
commit object name at the tip of the master branch" in the older days,
but not anymore, as refs can be packed into $GIT_DIR/packed-refs file.

Update the document to talk in terms of a more abstract concept "ref" and
"symbolic ref" where we are not describing the underlying implementation
detail.

This on purpose leaves two instances of $GIT_DIR/ in the git-remote
documentation; they do talk about $GIT_DIR/remotes/ and $GIT_DIR/branches/
file hierarchy that used to be the place to store configuration around
remotes before the configuration mechanism took them over.

it is convenient to only relink instead of doing a full make clean;

This change complements the auto-detection of changes to CFLAGS that

84054f79de clone: accept config options on the command line
Clone does all of init, "remote add", fetch, and checkout
without giving the user a chance to intervene and set any
configuration. This patch allows you to set config options
in the newly created repository after the clone, but before
we do any other operations.

In many cases, this is a minor convenience over something
like:

  git clone git://...
  git config core.whatever true

But in some cases, it can bring extra efficiency by changing
how the fetch or checkout work. For example, setting
line-ending config before the checkout avoids having to
re-checkout all of the contents with the correct line
endings.

It also provides a mechanism for passing information to remote
helpers during a clone; the helpers may read the git config
to influence how they operate.

1c2c9bee1b config: die on error in command-line config
The error handling for git_config is somewhat confusing. We
collect errors from running git_config_from_file on the
various config files and carefully pass them back up. But
the two odd things are:

  1. We actually die on most errors in git_config_from_file.
     In fact, the only error we actually pass back up is if
     fopen() fails on the file.

  2. Most callers of git_config do not check the error
     return at all, but will continue if git_config reports
     an error.

When the code for "git -c core.foo=bar" was added, it
dutifully passed errors up the call stack, only for them to
be eventually ignored. This makes it inconsistent with the
file-parsing code, which will die when it sees malformed
config. And it's somewhat unsafe, because it means an error
in parsing a typo like:

  git -c clean.requireforce=ture clean

will continue the command, ignoring the config the user
tried to give.

28fc3a6857 strbuf_split: add a max parameter
Sometimes when splitting, you only want a limited number of
fields, and for the final field to contain "everything
else", even if it includes the delimiter.

This patch introduces strbuf_split_max, which provides a
"max number of fields" parameter; it behaves similarly to
perl's "split" with a 3rd field.

The existing 2-argument form of strbuf_split is retained for
compatibility and ease-of-use.

7ddc2710b9 Add profile feedback build to git
Add a gcc profile feedback build option "profile-all" to the main
Makefile. It simply runs the test suite to generate feedback data and the
recompiles the main executables with that. The basic structure is similar
to the existing gcov code.

gcc is often able to generate better code with profile feedback data. The
training load also doesn't need to be too similar to the actual load, it
still gives benefits.

The test suite run is unfortunately quite long. It would be good to find a
suitable subset that runs faster and still gives reasonable feedback.

For now the test suite runs single threaded (I had some trouble running
the test suite with -jX)

I tested it with git gc and git blame kernel/sched.c on a Linux kernel
tree. For gc I get about 2.7% improvement in wall clock time by using the
feedback build, for blame about 2.4%.  That's not gigantic, but not shabby
either for a very small patch.

If anyone has any favourite CPU intensive git benchmarks feel free to try
them too.

I hope distributors will switch to use a feedback build in their packages.

the call from potentially overwriting other variables that are initialized
from the configuration.

12bf828348 rebase -i -p: include non-first-parent commits in todo list
Consider this graph:

        D---E    (topic, HEAD)
       /   /
  A---B---C      (master)
   \
    F            (topic2)

and the following three commands:
  1. git rebase -i -p A
  2. git rebase -i -p --onto F A
  3. git rebase -i -p B

Currently, (1) and (2) will pick B, D, C, and E onto A and F,
respectively.  However, (3) will only pick D and E onto B, but not C,
which is inconsistent with (1) and (2).  As a result, we cannot modify C
during the interactive-rebase.

The current behavior also creates a bug if we do:
  4. git rebase -i -p C

In (4), E is never picked.  And since interactive-rebase resets "HEAD"
to "onto" before picking any commits, D and E are lost after the
interactive-rebase.

This patch fixes the inconsistency and bug by ensuring that all children
of upstream are always picked.  This essentially reverts the commit:
  d80d6bc146

When compiling the todo list, commits reachable from "upstream" should
never be skipped under any conditions.  Otherwise, we lose the ability
to modify them like (3), and create a bug like (4).

Two of the tests contain a scenario like (3).  Since the new behavior
added more commits for picking, these tests need to be updated to
account for the additional pick lines.  A new test has also been added
for (4).

36bfb0e5f6 tests: link shell libraries into valgrind directory
When we run tests under valgrind, we symlink anything
executable that starts with git-* or test-* into a special
valgrind bin directory, and then make that our
GIT_EXEC_PATH.

However, shell libraries like git-sh-setup do not have the
executable bit marked, and did not get symlinked.  This
means that any test looking for shell libraries in our
exec-path would fail to find them, even though that is a
fine thing to do when testing against a regular git build
(or in a git install, for that matter).

t2300 demonstrated this problem. The fix is to symlink these
shell libraries directly into the valgrind directory.

all platforms (SunOS 5.7) and will cause a compilation failure.  So, let's
remove it.
