Stefan Beller 109cd76dd3 object: add repository argument to parse_object
Add a repository argument to allow the callers of parse_object
to be more specific about which repository to act on. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.

Jeff King 368b4e5906 index-pack: handle --strict checks of non-repo packs
Commit 73c3f0f704 (index-pack: check .gitmodules files with
--strict, 2018-05-04) added a call to add_packed_git(), with
the intent that the newly-indexed objects would be available
to the process when we run fsck_finish().  But that's not
what add_packed_git() does. It only allocates the struct,
and you must install_packed_git() on the result. So that
call was effectively doing nothing (except leaking a
struct).

But wait, we passed all of the tests! Does that mean we
don't need the call at all?

For normal cases, no. When we run "index-pack --stdin"
inside a repository, we write the new pack into the object
directory. If fsck_finish() needs to access one of the new
objects, then our initial lookup will fail to find it, but
we'll follow up by running reprepare_packed_git() and
looking again. That logic was meant to handle somebody else
repacking simultaneously, but it ends up working for us
here.

But there is a case that does need this, that we were not
testing. You can run "git index-pack foo.pack" on any file,
even when it is not inside the object directory. Or you may
not even be in a repository at all! This case fails without
doing the proper install_packed_git() call.

We can make this work by adding the install call.

Note that we should be prepared to handle add_packed_git()
failing. We can just silently ignore this case, though. If
fsck_finish() later needs the objects and they're not
available, it will complain itself. And if it doesn't
(because we were able to resolve the whole fsck in the first
pass), then it actually isn't an interesting error at all.

Nguyễn Thái Ngọc Duy 431bb23a27 am: move advice.amWorkDir parsing back to advice.c
The only benefit from this move (apart from cleaner code) is that
advice.amWorkDir should now show up in `git help --config`. There
should be no regression since advice config is always read by the
git_default_config().

While at there, use advise() like other code. We now get "hint: "
prefix and the output is stderr instead of stdout (which is also the
reason for the test update because stderr is checked in a following
test and the extra advice can fail it).

Nguyễn Thái Ngọc Duy 3ac68a93fd help: add --config to list all available config
Sometimes it helps to list all available config vars so the user can
search for something they want. The config man page can also be used
but it's harder to search if you want to focus on the variable name,
for example.

This is not the best way to collect the available config since it's
not precise. Ideally we should have a centralized list of config in C
code (pretty much like 'struct option'), but that's a lot more work.
This will do for now.

Nguyễn Thái Ngọc Duy a73b3680c4 Add and use generic name->id mapping code for color slot parsing
Instead of hard coding the name-to-id mapping in C code, keep it in an
array and use a common function to do the parsing. This reduces code
and also allows us to list all possible color slots later.

This starts using C99 designated initializers more for convenience
(the first designated initializers have been introduced in builtin/clean.c
for some time without complaints)

Nguyễn Thái Ngọc Duy 3fe735e723 completion: suppress some -no- options
Most --no- options do have some use, even if rarely to negate some
option that's specified in an alias.

These options --no-ours and --no-theirs however have no clear
semantics. If I specify "--ours --no-theirs", the second will reset
writeout stage and is equivalent of "--no-ours --no-theirs" which is
not that easy to see. Drop them. You can either switch from --ours to
--theirs and back but you can never negate them.

Nguyễn Thái Ngọc Duy 0231ae71d3 diff: turn --ita-invisible-in-index on by default
Due to the implementation detail of intent-to-add entries, the current
"git diff" (i.e. no treeish or --cached argument) would show the
changes in the i-t-a file, but it does not mark the file as new, while
"diff --cached" would mark the file as new while showing its content
as empty.

     $ git diff                     | $ diff --cached
    --------------------------------|-------------------------------
     diff --git a/new b/new         | diff --git a/new b/new
     index e69de29..5ad28e2 100644  | new file mode 100644

     +haha                          |

One evidence of the current output being wrong is that, the output
from "git diff" (with ita entries) cannot be applied because it
assumes empty files exist before applying.

Turning on --ita-invisible-in-index [1] [2] would fix this. The result
is "new file" line moving from "git diff --cached" to "git diff".

     $ git diff                     | $ diff --cached
    --------------------------------|-------------------------------
     diff --git a/new b/new         |

This option is on by default in git-status [1] but we need more fixup
in rename detection code [3]. Luckily we don't need to do anything
else for the rename detection code in diff.c (wt-status.c uses a
customized one).

Jeff King ff417260cf make show-index a builtin
The git-show-index command is built as its own separate
program. There's really no good reason for this, and it
means we waste extra space on disk (and CPU time running the
linker). Let's fold it in to the main binary as a builtin.

The history here is actually a bit amusing. The program
itself is mostly self-contained, and doesn't even use our
normal pack index code. In a5031214c4 (slim down "git
show-index", 2010-01-21), we even stopped using xmalloc() so
that it could avoid libgit.a entirely. But then 040a655116
(cleanup: use internal memory allocation wrapper functions
everywhere, 2011-10-06) switched that back to xmalloc, which
later become ALLOC_ARRAY().

Making it a builtin should give us the best of both worlds:
no wasted space and no need to avoid the usual patterns.

Elijah Newren 0ed556d38f rev-parse: check lookup'ed commit references for NULL
Commits 2122f8b963 ("rev-parse: Add support for the ^! and ^@ syntax",
2008-07-26) and 3dd4e7320d ("Teach rev-parse the ... syntax.", 2006-07-04)
taught rev-parse new syntax, and used lookup_commit_reference() as part of
their logic.  Neither usage checked the returned commit to see if it was
non-NULL before using it.  Check for NULL and ensure an appropriate error
is reported to the user.

Reported by Florian Weimer and Todd Zullinger.
