t4034: bulk verify builtin word regex sanity

The builtin word regexes should be tested with some simple examples
against simple issues. Do this in bulk.

Mainly due to a lack of language knowledge and inspiration, most of
the test cases (cpp, csharp, java, objc, pascal, php, python, ruby)
are directly based off a C operator precedence table to verify that
all operators are split correctly. This means that they are probably
incomplete or inaccurate except for 'cpp' itself.

Still, they are good enough to already have uncovered a typo in the
python and ruby patterns.

'fortran' is based on my anecdotal knowledge of the DO10I parsing
rules, and thus probably useless. The rest (bibtex, html, tex) are an
ad-hoc test of what I consider important splits in those languages.

t0000 contains two snippets of actual test output. This causes
problems when passing -v to the test[*]: the test infrastructure
echoes the tests before running them, and the TAP parser then sees
this test output and concludes that two tests failed and that the TAP
output was badly formatted.

Guard against this by quoting the output in the source.

t9010: svnadmin can fail even if available

If svn is built against one version of SQLite and run against another,
libsvn_subr needlessly errors out in operations that need to make a
commit.

That is clearly not a bug in git but let us consider the ramifications for
the test suite. git-svn uses libsvn directly and is probably broken by
that bug; it is right for git-svn tests to fail. The vcs-svn lib, on the
other hand, does not use libsvn and the test t9010 only uses svn to check
its work. This points to two possible improvements:

- do not disable most vcs-svn tests if svn is missing.
- skip validation rather than failing it when svn fails.

Bring about both by putting the svn invocations into a single test that
builds a repo to compare the test-svn-fe result against. The test will
always pass but only will set the new SVNREPO test prereq if svn succeeds;
and validation using that repo gets an SVNREPO prerequisite so it only
runs with working svn installations.

The documentation for the post-rewrite hook contains a paragraph from

versions of the series implemented notes copying as a core feature.

Thus mentioning post-rewrite-copy-notes was never correct. As the

unless they ship a sample hook in either templates or contrib, we

The test using the conflict_hunks helper function (test 9) fails

gitweb: remove unnecessary test when closing file descriptor

It happens that closing file descriptor fails whereas the blob is
perfectly readable. According to perlman the reasons could be:

If the file handle came from a piped open, "close" will additionally
return false if one of the other system calls involved fails, or if the
program exits with non-zero status. (If the only problem was that the
program exited non-zero, $! will be set to 0.) Closing a pipe also waits
for the process executing on the pipe to complete, in case you want to
look at the output of the pipe afterwards, and implicitly puts the exit
status value of that command into $?.

Prematurely closing the read end of a pipe (i.e. before the process writ-
ing to it at the other end has closed it) will result in a SIGPIPE being
delivered to the writer. If the other end can't handle that, be sure to
read all the data before closing the pipe.

In this case we don't mind that close fails.

lib-git-svn.sh: Move web-server handling code into separate function

This library file is currently sourced by 57 test files, of which
only four may (optionally) start a web-server in order to access
the svn repo via an http url, rather than a file url.

In addition to isolating the current web-server handling code from
the majority of tests, in a new prepare_httpd function, we also
add some more error checking and reporting code to validate the
apache installation. Only those tests which attempt to start the
web-server, by calling start_httpd, will execute this code.

Note that it is important for start_httpd to return an error
indication, if prepare_httpd fails, so that the failure to use
the web-server, as requested by the user, should not go unnoticed.
(Unless the svnrepo variable is set to an http url at the end of
start_httpd, the remaining tests will use file urls, without
comment.)

cvsimport: handle the parsing of uppercase config options

The current code leads to

fatal: bad config value for 'cvsimport.r' in .git/config

for a standard use case with cvsimport.r set.

cvsimport sets internal variables by checking the config for each
possible command line option. The problem is that config items are case
insensitive, so config.r and config.R are the same. The ugly error is
due to that fact that cvsimport expects a bool for -R (and thus
config.R) but a remote name for -r (and thus config.r).

Fix this by making cvsimport expect long names for uppercase options.

config options for cvsimport have been undocumented so far, though
present in the code and advertised in several tutorials. So one may read
"enhance" for "fix". Similarly, the names for the options are
"documented" in the code, waitiing for their lowercase equivalents to be
transformed into long config options, as well.

being run for this purpose from the presence of the --serve command
line flag.

When running with <ok_path> arguments, the --serve flag is treated
as one of the path arguments and the special child behavior does
not kick in. So the child becomes an ordinary git daemon process,
notices that all the addresses it needs are in use, and exits with
the message "fatal: unable to allocate any listen sockets on port
9418".

Fix it by putting --serve at the beginning of the command line,
where the flag cannot be mistaken for a path argument.

t9001: use older Getopt::Long boolean prefix '--no' rather than '--no-'

The '--no-chain-reply-to' option is a Getopt::Long boolean option. The
'--no-' prefix (as in --no-chain-reply-to) for boolean options is not
supported in Getopt::Long version 2.32 which was released with Perl 5.8.0.
This version only supports '--no' as in '--nochain-reply-to'. More recent
versions of Getopt::Long, such as version 2.34, support either prefix. So
use the older form in the tests.

Fix false positives in t3404 due to SHELL=/bin/false

If the user's shell in NSS passwd is /bin/false (eg as found during Gentoo's
package building), the git-rebase exec tests will fail, because they call
$SHELL around the command, and in the existing testcase, $SHELL was not being
cleared sufficently.

This lead to false positive failures of t3404 on systems where the package
build user was locked down as noted above.

diff: funcname and word patterns for perl

The default function name discovery already works quite well for Perl
code... with the exception of here-documents (or rather their ending).

sub foo {
print <<END
here-document
END
return 1;
}

The default funcname pattern treats the unindented END line as a
function declaration and puts it in the @@ line of diff and "grep
--show-function" output.

With a little knowledge of perl syntax, we can do better. You can
try it out by adding "*.perl diff=perl" to the gitattributes file.

setup_work_tree: adjust relative $GIT_WORK_TREE after moving cwd

When setup_work_tree() is called, it moves cwd to $GIT_WORK_TREE and
makes internal copy of $GIT_WORK_TREE absolute. The environt variable,
if set by user, remains unchanged. If the variable is relative, it is
no longer correct because its base dir has changed.

Instead of making $GIT_WORK_TREE absolute too, we just say "." and let
subsequent git processes handle it.

Regular expressions in awk have been extended somewhat...
One sequence that is not supported is hexadecimal value escapes

t0001: test git init when run via an alias

Add some tests to document the correct behavior of (possibly aliased)
init when run within and outside a git directory.

If I set up a simple git alias “quietinit = init --quiet”, usually it
will work just like ‘git init --quiet’.

There are some differences, unfortunately, since in the process of
checking for aliases, git has to look for a .git/config file. If ‘git
quietinit’ is run from a subdirectory of an existing git repository,
that repository’s configuration will affect the configuration of the
new repository. In particular, the new repository can inherit
bogus values for core.bare and core.worktree.

is to handle that. The extra code can now be retired.

Also note that setup_explicit assignment is removed, worktree setting

setup: limit get_git_work_tree()'s to explicit setup case only

get_git_work_tree() takes input as core.worktree, core.bare,
GIT_WORK_TREE and decides correct worktree setting.

Unfortunately it does not do its job well. core.worktree and
GIT_WORK_TREE should only be taken into account, if GIT_DIR is set
(which is handled by setup_explicit_git_dir). For other setup cases,
only core.bare matters.

Add a temporary variable setup_explicit to adjust get_git_work_tree()
behavior as such. This variable will be gone once setup_* rework is
done.

Also remove is_bare_repository_cfg check in set_git_work_tree() to
ease the rework. We are going to check for core.bare and core.worktree
early before setting worktree. For example, if core.bare is true, no
need to set worktree.
