Submodules: Use "ignore" settings from .gitmodules too for diff and status
The .gitmodules file is parsed for "submodule.<name>.ignore" entries
before looking for them in .git/config. Thus settings found in .git/config
will override those from .gitmodules, thereby allowing the local developer
to ignore settings given by the remote side while also letting upstream
set defaults for those users who don't have special needs.

Submodules: Add the new "ignore" config option for diff and status
The new "ignore" config option controls the default behavior for "git
status" and the diff family. It specifies under what circumstances they
consider submodules as modified and can be set separately for each
submodule.
The command line option "--ignore-submodules=" has been extended to accept
the new parameter "none" for both status and diff.
Users that chose submodules to get rid of long work tree scanning times
might want to set the "dirty" option for those submodules. This brings
back the pre 1.7.0 behavior, where submodule work trees were never
scanned for modifications. By using "--ignore-submodules=none" on the
command line the status and diff commands can be told to do a full scan.
This option can be set to the following values (which have the same name
and meaning as for the "--ignore-submodules" option of status and diff):
"all": All changes to the submodule will be ignored.
"dirty": Only differences of the commit recorded in the superproject and
the submodules HEAD will be considered modifications, all changes
to the work tree of the submodule will be ignored. When using this
value, the submodule will not be scanned for work tree changes at
all, leading to a performance benefit on large submodules.
"untracked": Only untracked files in the submodules work tree are ignored,
a changed HEAD and/or modified files in the submodule will mark it
as modified.
"none" (which is the default): Either untracked or modified files in a
submodules work tree or a difference between the subdmodules HEAD
and the commit recorded in the superproject will make it show up
as changed. This value is added as a new parameter for the
"--ignore-submodules" option of the diff family and "git status"
so the user can override the settings in the configuration.

t/{t5541,lib-httpd}: replace problematic '!()' notation with test_must_fail
The '!()' notation is interpreted as a pattern-list on Ksh. The Ksh man

!(pattern-list)

Ksh performs a file glob using the pattern-list and then tries to execute
the first file in the list. If a space is added between the '!' and the
open parens, then Ksh will not interpret it as a pattern list, but in this
case, it is preferred to use test_must_fail, so lets do so.

73e25e7c (git --paginate: do not commit pager choice too early,
2010-06-26) failed to take some cases into account.
1b. Builtins that do not use RUN_SETUP (like git config) do
not find GIT_DIR set correctly when the pager is launched
from run_builtin(). So the core.pager configuration is
not honored from subdirectories of the toplevel for them.
4a. External git commands (like git request-pull) relied on the
early pager launch to take care of handling the -p option.
Ever since 73e25e7c, they do not honor the -p option at all.
4b. Commands invoked through ! aliases (like ls) were also relying
on the early pager launch.
Fix (4a) by launching the pager (if requested) before running such a
“dashed external”. For simplicity, this still does not search for a
.git directory before running the external command; when run from a
subdirectory of the toplevel, therefore, the “[core] pager”
configuration is still not honored.
Fix (4b) by launching pager if requested before carrying out such an
alias. Actually doing this has no effect, since the pager (if any)
would have already been launched in a failed attempt to try a
dashed external first. The choice-of-pager-not-honored-from-
subdirectory bug still applies here, too.
(1b) is not a regression. There is no need to fix it yet.

In 456156d a shortcut to priming the index tree reference was
introduced, but the justification for it was completely bogus.
"read-tree -m A B" is to take the index (and the working tree)
that is largely based on (but does not have to match exactly) A
and update it to B, while carrying the local change that does
not overlap the difference between A and B, so there is no reason
to expect that the resulting index should match the tree B.
Reorganize `git-log' man page to clarify common diff options.
This will reduce considerably the common confusion where people miss the
`--follow' option, and wonder why `-M'/`-C' is not working.
* Move the diff options include to after the log-specific flags, and add
a "Common diff options" subtitle before them. (These options apply
only when patches are shown, which is not a common use case among
newbies, so having them first is confusing.)
* Move the `--follow' description to the top of the listed options. The
options before that seem less important: `--full-diff' applies only
when patches are shown, `--source' and `--decorate' are less useful
with many common commit specifications.

do not write out index when status does not have to

Makefile: work around ksh's failure to handle missing list argument to for loop
ksh does not like it when the list argument is missing in a 'for' loop.
This can happen when NO_CURL is set which causes REMOTE_CURL_ALIASES to be
unset. In this case, the 'for' loop in the Makefile is expanded to look
like this:
for p in ; do
and ksh complains like this:
/bin/ksh: syntax error at line 15 : `;' unexpected
The existing attempt to work around this issue, introduced by 70b89f87,
tried to protect the 'for' loop by first testing whether REMOTE_CURL_ALIASES
was empty, but this does not work since, as Johannes Sixt explains, "Before
the test for emptyness can happen, the complete statement must be parsed,
but ksh finds a syntax error in the statement and, therefore, cannot even
begin to execute the statement. (ksh doesn't follow POSIX in this regard,
where this would not be a syntax error.)".
Make's $(foreach) function could be used to avoid this shell glitch, but
since it has already caused a problem once before by generating a command
line that exceeded the maximum argument list length on IRIX, let's adopt
Bruce Stephens's suggestion for working around this issue in the same way
the OpenSSL folks have done it. This solution first assigns the contents
of the REMOTE_CURL_ALIASES make variable to a shell variable and then
supplies the shell variable as the list argument in the 'for' loop. This
satisfies ksh and has the expected behavior even if $(REMOTE_CURL_ALIASES)
is empty.

parse_date: fix signedness in timezone calculation

However, our timestamp is stored as an unsigned integer,

and our numeric timezone is in the millions of hours. You

git submodule add <url> hlagh
git-submodule will get as far as checking out the remote repository
into hlagh, but it'll die right afterwards when it fails to add the
new path:
The following paths are ignored by one of your .gitignore files:
hlagh
Use -f if you really want to add them.
fatal: no files added
Failed to add submodule 'hlagh'
Currently there's no way to add a submodule in this situation other
than to remove the ignored path from the .gitignore while I'm at it.
That's silly, when you run `git submodule add' you're explicitly
saying that you want to add something *new* to the repository. Instead
it should just add the path with `git add --force'.
Initially I implemented this by adding new -f and --force options to
`git submodule add'. But if the --force option isn't supplied it'll
get as far as cloning `hlagh', but won't add it.
So the first thing the user has to do is to remove `hlagh' and then
try again with the --force option.
That sucks, it should just add the path to begin with. I can't think
of any usecase where you've gone through the trouble of typing out
`git submodule add ..', but wish to be overriden by a `gitignore'. The
submodule semantics should be more like `git init', not `git add'.

Add a "Do's, don'ts & things to keep in mind" subsection to the
"Writing Tests" documentation. Much of this is based on Junio C
Hamano's "Test your stuff" section in
<7vhbkj2kcr.fsf@alter.siamese.dyndns.org>.
I turned it into a list of do's and don'ts to make it easier to skim
it, and integrated my note that a TAP harness will get confused if you
print "ok" or "not ok" at the beginning of a line.
