f70d0586d6 Documentation/rev-list-options.txt: Fix missing line in example history graph
In the detailed explanation of how the revision machinery does history
simplification, the current text presents an example history and explains
how various options of the revision machinery affect the resulting list
of commits. The first simplification mode mentioned is the default mode,
in which a number of commits is omitted from the example graph according
to the history simplification rules. The text states (among other things)
that commit "C was considered via N, but is TREESAME", and therefore
omitted. However, the accompanying graph does not list the effect on the
implicit parentage, i.e. that commit I takes C's place as a parent of N.

Running 'git rev-list --parents P' does indeed list I as a second parent
of N, and the accompanying graph should therefore also show this line.

By default reflogs are always created for new local branches by
"checkout -b".  But by setting core.logAllRefUpdates to false this will
not be true anymore.

In that case you only create the reflogs when you use -l switch with

2de03ebe06 t9129: fix UTF-8 locale detection
The UTF-8 prerequisite test checked explicitly for en_US.utf8 in the
output from "locale -a", but the tests that are actually protected by the
prerequisite were asking LC_ALL=en_US.UTF-8 from the system.

This inconsistency leads the tests to fail on platforms that do not know
both en_US.UTF-8 and en_US.utf8 (thanks you, Yann Droneaud, for bringing
this up with an initial patch).

Instead, pick a locale with ".UTF-8" (with or without hyphen, spelled in
either upper or lowercase) in its name from "locale -a" output, and use it
for running the test.

78646987e4 git-instaweb: Add support for running gitweb via 'plackup'
PSGI is an interface between Perl web applications and web servers, and
Plack is a Perl module and toolkit that contains PSGI middleware, helpers
and adapters to web servers; see http://plackperl.org

PSGI and Plack are inspired by Python's WSGI and Ruby's Rack (and
probably JavaScript's Jack/JSGI).

Plack core distribution includes HTTP::Server::PSGI, a reference PSGI
standalone web server implementation.  'plackup' is a command line
launcher to run PSGI applications from command line, connecting web
app to a web server via Plack::Runner module.  By default it uses
HTTP::Server::PSGI as a web server.

git-instaweb generates gitweb.psgi wrapper (in $GIT_DIR/gitweb).  This
wrapper uses Plack::App::WrapCGI to compile gitweb.cgi (which is a CGI
script) into a PSGI application using CGI::Compile and CGI::Emulate::PSGI.
git-instaweb then runs this wrapper, using by default HTTP::Server::PSGI
standalone Perl server, via Plack::Runner.

The configuration for 'plackup' is currently embedded in generated
gitweb.psgi wrapper, instead of using httpd.conf ($conf).

To run git-instaweb with '--httpd=plackup', you need to have instaled
Plack core, CGI::Emulate::PSGI, CGI::Compile.  Those modules have to be
available for Perl scripts (which can be done for example by setting
PERL5LIB environment variable).  This is currently not documented.

d94775e1f9 git-instaweb: Wait for server to start before running web browser
Add generic httpd_is_ready subroutine, which busy-waits for web server to
be started, by checking if $port is opened on localhost.  This is used to
avoid situation where web browser is started before web server is ready to
accept connection, and fails.

It uses IO::Socket::INET module, which is core Perl module since v5.6.0.

Alternate solution, possible for those web servers that can run arbitrary
code hooks after they bind the listen socket (after they start accepting
connections), would be to use some kind of blocking mechanism: FIFO or
lockfile, see
  http://thread.gmane.org/gmane.comp.version-control.git/147337/focus=147566

This can be always added later, as a web server specific branch in
httpd_is_ready function.

d1127622f5 git-instaweb: Remove pidfile after stopping web server
This way running e.g. "git instaweb" after "git instaweb --stop" would
not try to kill already stopped web server.

This is probably important only for those web servers that are
"daemonized" by git-instaweb itself, i.e. for those where it is
git-instaweb that creates pidfile.  Currently it is includes only
'mongoose' web server, but it would also include 'plackup' web server
(added in later commit).

7e2bfd3f99 revert: allow cherry-picking more than one commit
This makes it possible to pass many commits or ranges of
commits to "git cherry-pick" and to "git revert" to process
many commits instead of just one.

In fact commits are now enumerated with an equivalent of

	git rev-list --no-walk "$@"

so all the following are now possible:

	git cherry-pick master~2..master
	git cherry-pick ^master~2 master
	git cherry-pick master^ master

The following should be possible but does not work:

	git cherry-pick -2 master

because "git rev-list --no-walk -2 master" only outputs
one commit as "--no-walk" seems to take over "-2".

And there is currently no way to continue cherry-picking or
reverting if there is a problem with one commit. It's also
not possible to abort the whole process. Some future work
should provide the --continue and --abort options to do
just that.

53dfac44c9 git-request-pull.sh: remove -e switch to shell interpreter which breaks ksh
The -e option causes the shell to exit immediately when a command exits
with a non-zero exit status.  This does not seem to cause a problem for
Bash, but it does cause a problem for the Korn shell, like Solaris's
xpg4/sh, whose unset utility returns non-zero if it is passed a variable
name which was not previously set.  When using xpg4/sh, git-request-pull
exits while sourcing git-sh-setup since git-sh-setup tries to unset the
CDPATH environment variable.

When git-request-pull was originally written, it did not do any error
checking and it used this shell feature to exit when an error occurred.
This script now performs proper error checking and provides useful error
messages, so this -e option appears to be merely a historical artifact and
can be removed.

Kudos to Jonathan Nieder for introducing t5150 which exercises the
request-pull code path.

5853caec96 DWIM 'git show -5' to 'git show --do-walk -5'
To show the last two commits with one command, one might try

 1) git show -s master~2..
 2) git show -s ^master~2 master
 3) git show -s master^ master
 4) git show -s -2 master

Choice (3) works because both commits are listed on the command line.
Choices (1) and (2) have worked ever since v1.6.4-rc~3 (Make 'git
show' more useful, 2009-07-13) disabled --no-walk in this case because
there is no other useful meaning for them to have.  Unfortunately, (4)
does not work: it outputs only one commit, because --no-walk stays on.

So disable --no-walk in this case so ‘git show’ and future ‘git
cherry-pick’ can behave as expected.

As a side effect, this unfortunately changes the meaning of
‘git log --oneline --decorate --no-walk -5 --all’: instead of listing
five refs, after this patch that command would list the five most
recent commits.

4297c0aeb5 Make --color-words work well with --graph
'--color-words' algorithm can be described as:

  1. collect a the minus/plus lines of a diff hunk, divided into
     minus-lines and plus-lines;

  2. break both minus-lines and plus-lines into words and
     place them into two mmfile_t with one word for each line;

  3. use xdiff to run diff on the two mmfile_t to get the words level diff;

And for the common parts of the both file, we output the plus side text.
diff_words->current_plus is used to trace the current position of the plus file
which printed. diff_words->last_minus is used to trace the last minus word
printed.

For '--graph' to work with '--color-words', we need to output the graph prefix
on each line of color words output. Generally, there are two conditions on
which we should output the prefix.

  1. diff_words->last_minus == 0 &&
     diff_words->current_plus == diff_words->plus.text.ptr

     that is: the plus text must start as a new line, and if there is no minus
     word printed, a graph prefix must be printed.

  2. diff_words->current_plus > diff_words->plus.text.ptr &&
     *(diff_words->current_plus - 1) == '\n'

     that is: a graph prefix must be printed following a '\n'

b5a4de9d50 graph.c: register a callback for graph output
It will look better if the 'git log --graph' print
the graph pading lines before the diff output just
like what it does for commit message.
And this patch leverage the new diff prefix callback
function to achieve this.
