e2c6f7cd5a Fix definition of ARRAY_SIZE for non-gcc builds
The improved ARRAY_SIZE macro uses BARF_UNLESS_AN_ARRAY which expands
to a valid check for recent gcc versions and to 0 for older gcc
versions but is not defined on non-gcc builds.

Non-gcc builds need this macro to expand to 0 as well. The current outer
test (defined(__GNUC__) && (__GNUC__ >= 3)) is a strictly weaker
condition than the inner test (GIT_GNUC_PREREQ(3, 1)) so we can omit the
outer test and cause the BARF_UNLESS_AN_ARRAY macro to be defined
correctly on non-gcc builds as well as gcc builds with older versions.

1335f73289 fsck: support ignoring objects in git fsck via fsck.skiplist
Identical to support in `git receive-pack for the config option
`receive.fsck.skiplist`, we now support ignoring given objects in
`git fsck` via `fsck.skiplist` altogether.

This is extremely handy in case of legacy repositories where it would
cause more pain to change incorrect objects than to live with them
(e.g. a duplicate 'author' line in an early commit object).

cd94c6f91e fsck: git receive-pack: support excluding objects from fsck'ing
The optional new config option `receive.fsck.skipList` specifies the path
to a file listing the names, i.e. SHA-1s, one per line, of objects that
are to be ignored by `git receive-pack` when `receive.fsckObjects = true`.

This is extremely handy in case of legacy repositories where it would
cause more pain to change incorrect objects than to live with them
(e.g. a duplicate 'author' line in an early commit object).

The intended use case is for server administrators to inspect objects
that are reported by `git push` as being too problematic to enter the
repository, and to add the objects' SHA-1 to a (preferably sorted) file
when the objects are legitimate, i.e. when it is determined that those
problematic objects should be allowed to enter the server.

2becf00ff7 fsck: support demoting errors to warnings
We already have support in `git receive-pack` to deal with some legacy
repositories which have non-fatal issues.

Let's make `git fsck` itself useful with such repositories, too, by
allowing users to ignore known issues, or at least demote those issues
to mere warnings.

Example: `git -c fsck.missingEmail=ignore fsck` would hide
problems with missing emails in author, committer and tagger lines.

In the same spirit that `git receive-pack`'s usage of the fsck machinery
differs from `git fsck`'s – some of the non-fatal warnings in `git fsck`
are fatal with `git receive-pack` when receive.fsckObjects = true, for
example – we strictly separate the fsck.<msg-id> from the
receive.fsck.<msg-id> settings.

upgraded to errors by specifying `invalidTagName` and
`missingTaggerEntry` in the receive.fsck.<msg-id> config setting.

Incidentally, the missing tagger warning is now really shown as a warning
(as opposed to being reported with the "error:" prefix, as it used to be
the case before this commit).

efaba7cc77 fsck: optionally ignore specific fsck issues completely
An fsck issue in a legacy repository might be so common that one would
like not to bother the user with mentioning it at all. With this change,
that is possible by setting the respective message type to "ignore".

This change "abuses" the missingEmail=warn test to verify that "ignore"
is also accepted and works correctly. And while at it, it makes sure
that multiple options work, too (they are passed to unpack-objects or
index-pack as a comma-separated list via the --strict=... command-line
option).

When fsck_tag() identifies a problem with the commit, it should try
to make it possible to continue checking the commit object, in case the
user wants to demote the detected errors to mere warnings.

Just like fsck_commit(), there are certain problems that could hide other

encountered in the correct position, the 'tag' line – if there is any –
would not be handled at all.

c9ad147f83 fsck: handle multiple authors in commits specially
This problem has been detected in the wild, and is the primary reason
to introduce an option to demote certain fsck errors to warnings. Let's
offer to ignore this particular problem specifically.

Technically, we could handle such repositories by setting
receive.fsck.<msg-id> to missingCommitter=warn, but that could hide
missing tree objects in the same commit because we cannot continue
verifying any commit object after encountering a missing committer line,
while we can continue in the case of multiple author lines.

When fsck_commit() identifies a problem with the commit, it should try
to make it possible to continue checking the commit object, in case the
user wants to demote the detected errors to mere warnings.

Note that some problems are too problematic to simply ignore. For
example, when the header lines are mixed up, we punt after encountering
an incorrect line. Therefore, demoting certain warnings to errors can
hide other problems. Example: demoting the missingauthor error to
a warning would hide a problematic committer line.

5d477a334a fsck (receive-pack): allow demoting errors to warnings
For example, missing emails in commit and tag objects can be demoted to
mere warnings with

	git config receive.fsck.missingemail=warn

The value is actually a comma-separated list.

In case that the same key is listed in multiple receive.fsck.<msg-id>
lines in the config, the latter configuration wins (this can happen for
example when both $HOME/.gitconfig and .git/config contain message type
settings).

As git receive-pack does not actually perform the checks, it hands off
the setting to index-pack or unpack-objects in the form of an optional
argument to the --strict option.

0282f4dced fsck: offer a function to demote fsck errors to warnings
There are legacy repositories out there whose older commits and tags
have issues that prevent pushing them when 'receive.fsckObjects' is set.
One real-life example is a commit object that has been hand-crafted to
list two authors.

Often, it is not possible to fix those issues without disrupting the
work with said repositories, yet it is still desirable to perform checks
by setting `receive.fsckObjects = true`. This commit is the first step
to allow demoting specific fsck issues to mere warnings.

The `fsck_set_msg_types()` function added by this commit parses a list
of settings in the form:

	missingemail=warn,badname=warn,...

Unfortunately, the FSCK_WARN/FSCK_ERROR flag is only really heeded by
git fsck so far, but other call paths (e.g. git index-pack --strict)
error out *always* no matter what type was specified. Therefore, we need
to take extra care to set all message types to FSCK_ERROR by default in
those cases.

78cc1a540b Revert "diff-lib.c: adjust position of i-t-a entries in diff"
This reverts commit d95d728aba.

It turns out that many other commands that need to interact with the
result of running diff-files and diff-index, e.g.  "git apply", "git
rm", etc., need to be adjusted to the new world order it brings in.
For example, it would break this sequence to correct a whitespace
breakage in the parts you changed:

	git add -N file
	git diff --cached file | git apply --cached --whitespace=fix
	git checkout file

In the old world order, "diff" showed a patch to modify an existing
empty file by adding its full contents, and "apply" updated the
index by modifying the existing empty blob (which is what an
Intent-to-Add entry records in the index) with that patch.

In the new world order, "diff" shows a patch to create a new file
with its full contents, but because "apply" thinks that the i-t-a
entry already exists in the index, it refused to accept a creation.

Adjusting "apply" to this new world order is easy, but we need to
assess the extent of the damage to the rest of the system the new
world order brought in before going forward and adjust them all,
after which we can resurrect the commit being reverted here.

d417c244ec contrib/subtree: fix broken &&-chains and revealed test error
This fixes two instances where a &&-chain was broken in the subtree
tests and fixes a test error that was revealed because of this.

Many tests in t7900-subtree.sh make a commit and then use 'undo' to
reset the state for the next test. In the 'check hash of split' test,
an 'undo' was being invoked after a 'subtree split' even though the
particular invocation of 'subtree split' did not actually make a commit.
The subsequent check_equal was failing, but this failure was masked by
that broken &&-chain.

Removing this undo causes the failing check_equal to succeed but breaks
the a check_equal later on in the same test.

It turns out that an earlier test ('check if --message for merge works
with squash too') makes a commit but doesn't 'undo' to the state
expected by the remaining tests. None of the intervening tests cared
enough about the state of the test repo to fail and the spurious 'undo'
in 'check hash of split' restored the expected state for any remaining
test that might care.

Adding the missing 'undo' to 'check if --message for merge works
with squash too' and removing the spurious one from 'check hash of
split' fixes all tests once the &&-chains are completed.

with Git coding guidelines resolve the inconsistency in favour of tabs.

2a514ed805 parse-options: move unsigned long option parsing out of pack-objects.c
The unsigned long option parsing (including 'k'/'m'/'g' suffix
parsing) is more widely applicable.  Add support for OPT_MAGNITUDE
to parse-options.h and change pack-objects.c use this support.

The error behavior on parse errors follows that of OPT_INTEGER.  The
name of the option that failed to parse is reported with a brief
message describing the expect format for the option argument and
then the full usage message for the command invoked.

This differs from the previous behavior for OPT_ULONG used in
pack-objects for --max-pack-size and --window-memory which used to
display the value supplied in the error message and did not display
the full usage message.
