b586744a86 test: skip clean-up when running under --immediate mode
Some tests try to be too careful about cleaning themselves up and
do

    test_expect_success description '
        set-up some test refs and/or configuration &&
        test_when_finished "revert the above changes" &&
	the real test
    '

Which is nice to make sure that a potential failure would not have
unexpected interaction with the next test. This however interferes when
"the real test" fails and we want to see what is going on, by running the
test with --immediate mode and descending into its trash directory after
the test stops. The precondition to run the real test and cause it to fail
is all gone after the clean-up procedure defined by test_when_finished is
done.

Update test_run_ which is the workhorse of running a test script
called from test_expect_success and test_expect_failure, so that we do not
run clean-up script defined with test_when_finished when a test that is
expected to succeed fails under the --immediate mode.

34840db834 rebase: do not print lots of usage hints after an obvious error message
When a non-existent branch was specified to be rebased, the complete
usage information is printed after the error message that carries the
relevant piece of information:

   $ git rebase master topci
   fatal: no such branch: topci
   usage: git rebase [-i] [options] [--onto <newbase>] [<upstream>] [<branch>]
      or: git rebase [-i] [options] --onto <newbase> --root [<branch>]
      or: git-rebase [-i] --continue | --abort | --skip

   Available options are
   [30 lines of usage stripped]

The error message was introduced recently by 4ac5356c (rebase: give a
better error message for bogus branch, 2011-01-27), and the result was
acceptable because the usage text was just two lines. But 45e2acf3
(rebase: define options in OPTIONS_SPEC, 2011-02-28) made things worse
because the usage text is now 35 lines.

Just drop the usage information because it does not add value to the
error message.

27269fc5f2 Documentation/i18n: quote double-dash for AsciiDoc
As explained in v1.7.3-rc0~13^2 (Work around em-dash handling in newer
AsciiDoc, 2010-08-23), if double dashes in names of commands are not
escaped, AsciiDoc renders them as em dashes.

While fixing that, spell the command name as "git sh-i18n--envsubst"
(2 words) instead of emphasizing the name of the binary (one
hyphenated name) and format it in italics.

The double-dash in the title should be escaped, too, to avoid spurious
em dashes in the header:

  .TH "GIT\-SH\-I18N\(emENVSUB" "1" "06/26/2011" "Git 1\&.7\&.6" "Git Manual"

AsciiDoc 8.6.4 with DocBook XSL 1.76.0-RC1 copes fine and writes
"GIT\-SH\-I18N\-\-ENVSUB" even without this change, which is why it
was missed before.

565e135a1e Documentation: quote double-dash for AsciiDoc
AsciiDoc versions since 5.0.6 treat a double-dash surrounded by spaces
(outside of verbatim environments) as a request to insert an em dash.
Such versions also treat the three-character sequence "\--", when not
followed by another dash, as a request to insert two literal minus
signs.  Thus from time to time there have been patches to add
backslashes to AsciiDoc markup to escape double-dashes that are meant
to be represent '--' characters used literally on the command line;
see v1.4.0-rc1~174, Fix up docs where "--" isn't displayed correctly,
2006-05-05, for example.

AsciiDoc 6.0.3 (2005-04-20) made life harder by also treating
double-dashes without surrounding whitespace as markup for an em dash,
though only when formatting for backends other than the manpages
(e.g., HTML).  Many pages needed to be changed to use a backslash
before the "--" in names of command-line flags like "--add" (see
v0.99.6~37, Update tutorial, 2005-08-30).

AsciiDoc 8.3.0 (2008-11-29) refined the em-dash rule to avoid that
requirement.  Double-dashes without surrounding spaces are not
rendered as em dashes any more unless bordered on both sides by
alphanumeric characters.  The unescaped markup for option names (e.g.,
"--add") works fine, and many instances of this style have leaked into
Documentation/; git's HTML documentation contains many spurious em
dashes when formatted by an older toolchain.  (This patch will not
change that.)

The upshot: "--" as an isolated word and in phrases like "git
web--browse" must be escaped if it is not to be rendered as an em dash
by current asciidoc.  Use "\--" to avoid such misformatting in
sentences in which "--" represents a literal double-minus command line
argument that separates options and revs from pathspecs, and use
"{litdd}" in cases where the double-dash is embedded in the command
name.  The latter is just for consistency with v1.7.3-rc0~13^2 (Work
around em-dash handling in newer AsciiDoc, 2010-08-23).

List of lines to fix found by grepping manpages for "(em".

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.

2cd9de3e18 submodule add: always initialize .git/config entry
When "git submodule add $path" is run to add a subdirectory $path to the
superproject, and $path is already the top of the working tree of the
submodule repository, the command created submodule.$path.url entry in the
configuration file in the superproject. However, when adding a repository
$URL that is outside the respository of the superproject to $path that
does not exist (yet) with "git submodule add $URL $path", the command
forgot to set it up.

The user is expressing the interest in the submodule and wants to keep a
checkout, the "submodule add" command should consistently set up the
submodule.$path.url entry in either case.

As a result "git submodule init" can't simply skip the initialization of
those submodules for which it finds an url entry in the git./config
anymore. That lead to problems when adding a submodule (which now sets the
url), add the "update" setting to .gitmodules and expect init to copy that
into .git/config like it is done in t7406. So change init to only then
copy the "url" and "update" entries when they don't exist yet in the
.git/config and do nothing otherwise.

ccee60862b submodule sync: do not auto-vivify uninteresting submodule
Earlier 33f072f (submodule sync: Update "submodule.<name>.url" for empty
directories, 2010-10-08) attempted to fix a bug where "git submodule sync"
command does not update the URL if the current superproject does not have
a checkout of the submodule.

However, it did so by unconditionally registering submodule.$name.url to
every submodule in the project, even the ones that the user has never
showed interest in at all by running 'git submodule init' command. This
caused subsequent 'git submodule update' to start cloning/updating submodules
that are not interesting to the user at all.

Update the code so that the URL is updated from the .gitmodules file only
for submodules that already have submodule.$name.url entries, i.e. the
ones the user has showed interested in having a checkout.

787513027a stash: Add --include-untracked option to stash and remove all untracked files
The --include-untracked option acts like the normal "git stash save" but
also adds all untracked files in the working directory to the stash and then
calls "git clean --force --quiet" to restore the working directory to a
pristine state.

This is useful for projects that need to run release scripts. With this
option, the release scripts can be from the main working directory so one
does not have to maintain a "clean" directory in parallel just for
releasing. Basically the work-flow becomes:

   $ git tag release-1.0
   $ git stash --include-untracked
   $ make release
   $ git clean -f
   $ git stash pop

"git stash" alone is not enough in this case--it leaves untracked files
lying around that might mess up a release process that expects everything to
be very clean or might let a release succeed that should actually fail (due
to a new source file being created that hasn't been committed yet).

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.

6ee9033d67 gitweb: Refactor git_header_html
Extract the following parts into separate subroutines:

 * finding correct MIME content type for HTML pages (text/html or
   application/xhtml+xml?) into get_content_type_html()
 * printing <link ...> elements in HTML head into print_header_links()
 * printing navigation "breadcrumbs" for given action into
   print_nav_breadcrumbs()
 * printing search form into print_search_form()

This reduces git_header_html to two pages long (53 lines), making gitweb
code easier to read.

d9a25fca5f Makefile: Track changes to LDFLAGS and relink when necessary
Some profiling tools (e.g., google-perftools and mutrace) work by
linking in a new library into the executables. When using these tools
it is convenient to only relink instead of doing a full make clean;
make cycle.

This change complements the auto-detection of changes to CFLAGS that
we already have. Tracking of more variables that affect the build can
be added when the need arise.

1ae05be4aa gitweb: Make git_search_* subroutines render whole pages
Move git_header_html() and git_footer_html() invocation from git_search()
to individual git_search_* subroutines.

While at it, reorganize search-related code a bit, moving invoking of git
commands before any output is generated.

This has the following advantages:

  * gitweb now shows an error page if there was unknown search type
    (evaluate_and_validate_params checks only that it looks sanely);
    remember that we shouldn't call die_error after any output.

  * git_search_message is now safe agains die_error in parse_commits
    (though this is very unlikely).

  * gitweb now can check errors while invoking git commands and show
    error page (again, quite unlikely).

882541b87d gitweb: Clean up code in git_search_* subroutines
Replace sequence of

       $foo .= "bar";
       $foo .= "baz";

with

       $foo .= "bar" .
	       "baz";

Use href(-replay=>1, -page=>undef) for first page of a multipl-page view.

Wrap some lines to reduce their length. Some lines still have more than 80
characters, but lines are shorter now.

No functional changes intended.

16f20725bb gitweb: Split body of git_search into subroutines
Create separate subroutines for handling each of aspects of searching
the repository:

 * git_search_message ('commit', 'author', 'committer')
 * git_search_changes ('pickaxe')
 * git_search_content_of_files ('grep')

Almost pure code movement (and unindent), which you can check e.g. via

  $ git blame -w --date=short -C -C HEAD^..HEAD -- gitweb/gitweb.perl |
    grep -C 3 -e '^[^^]' | less -S

No functional changes intended.

e0ca364551 gitweb: Check permissions first in git_search
Check first if relevant features: 'search', 'pickaxe', 'grep', as
appropriate, are enabled before doing anything else in git_search.
This should make git_search code more clear.

While at it, expand a bit error message (e.g. 'Pickaxe' ->
'Pickaxe search').
