f616db6a5c builtin/pack-objects.c: mark more strings for translation
Most of these are straight forward. GETTEXT_POISON does catch the last
string in cmd_pack_objects(), but since this is --progress output, it's
not supposed to be machine-readable.

1a07e59c3e Update messages in preparation for i18n
Many messages will be marked for translation in the following
commits. This commit updates some of them to be more consistent and
reduce diff noise in those commits. Changes are

- keep the first letter of die(), error() and warning() in lowercase
- no full stop in die(), error() or warning() if it's single sentence
  messages
- indentation
- some messages are turned to BUG(), or prefixed with "BUG:" and will
  not be marked for i18n
- some messages are improved to give more information
- some messages are broken down by sentence to be i18n friendly
  (on the same token, combine multiple warning() into one big string)
- the trailing \n is converted to printf_ln if possible, or deleted
  if not redundant
- errno_errno() is used instead of explicit strerror()

The code to try seeing if a fetch is necessary in a submodule

9d2e330b17 ewah_read_mmap: bounds-check mmap reads
The on-disk ewah format tells us how big the ewah data is,
and we blindly read that much from the buffer without
considering whether the mmap'd data is long enough, which
can lead to out-of-bound reads.

Let's make sure we have data available before reading it,
both for the ewah header/footer as well as for the bit data
itself. In particular:

  - keep our ptr/len pair in sync as we move through the
    buffer, and check it before each read

  - check the size for integer overflow (this should be
    impossible on 64-bit, as the size is given as a 32-bit
    count of 8-byte words, but is possible on a 32-bit
    system)

  - return the number of bytes read as an ssize_t instead of
    an int, again to prevent integer overflow

  - compute the return value using a pointer difference;
    this should yield the same result as the existing code,
    but makes it more obvious that we got our computations
    right

The included test is far from comprehensive, as it just
picks a static point at which to truncate the generated
bitmap. But in practice this will hit in the middle of an
ewah and make sure we're at least exercising this code.

cf317877e3 t3200: clarify description of --set-upstream test
Support for the --set-upstream option was removed in 52668846ea
(builtin/branch: stop supporting the "--set-upstream" option,
2017-08-17). The change did not completely remove the command
due to an issue noted in the commit's log message.

So, a test was added to ensure that a command which uses the
'--set-upstream' option fails instead of silently acting as an alias
for the '--set-upstream-to' option due to option parsing features.

To avoid confusion, clarify that the option is disabled intentionally
in the corresponding test description.

The test is expected to be around as long as we intentionally fail
on seeing the '--set-upstream' option which in turn we expect to
do for a period of time after which we can be sure that existing
users of '--set-upstream' are aware that the option is no
longer supported.

037714252f tests: clean after SANITY tests
Some of our tests try to make sure Git behaves sensibly in a
read-only directory, by dropping 'w' permission bit before doing a
test and then restoring it after it is done.  The latter is needed
for the test framework to clean after itself without leaving a
leftover directory that cannot be removed.

Ancient parts of tests however arrange the above with

	chmod a-w . &&
	... do the test ...
	status=$?
	chmod 775 .
	(exit $status)

which obviously would not work if the test somehow dies before it
has the chance to do "chmod 775".  Rewrite them by following a more
robust pattern recently written tests use, which is

	test_when_finished "chmod 775 ." &&
	chmod a-w . &&
	... do the test ...

c12c9df527 fetch-pack: test explicitly that --all can fetch tag references pointing to non-commits
Fetch-pack --all became broken with respect to unusual tags in
5f0fc64513 (fetch-pack: eliminate spurious error messages, 2012-09-09),
and was fixed only recently in e9502c0a7f (fetch-pack: don't try to fetch
peel values with --all, 2018-06-11). However the test added in
e9502c0a7f does not explicitly cover all funky cases.

In order to be sure fetching funky tags will never break, let's
explicitly test all relevant cases with 4 tag objects pointing to 1) a
blob, 2) a tree, 3) a commit, and 4) another tag objects. The referenced
tag objects themselves are referenced from under regular refs/tags/*
namespace. Before e9502c0a7f `fetch-pack --all` was failing e.g. this way:

3deed5e078 git-p4: auto-size the block
git-p4 originally would fetch changes in one query. On large repos this
could fail because of the limits that Perforce imposes on the number of
items returned and the number of queries in the database.

To fix this, git-p4 learned to query changes in blocks of 512 changes,
However, this can be very slow - if you have a few million changes,
with each chunk taking about a second, it can be an hour or so.

Although it's possible to tune this value manually with the
"--changes-block-size" option, it's far from obvious to ordinary users
that this is what needs doing.

This change alters the block size dynamically by looking for the
specific error messages returned from the Perforce server, and reducing
the block size if the error is seen, either to the limit reported by the
server, or to half the current block size.

That means we can start out with a very large block size, and then let
it automatically drop down to a value that works without error, while
still failing correctly if some other error occurs.

f55b87c1c7 git-p4: add options --commit and --disable-rebase
On a daily work with multiple local git branches, the usual way to
submit only a specified commit was to cherry-pick the commit on
master then run git-p4 submit.  It can be very annoying to switch
between local branches and master, only to submit one commit.  The
proposed new way is to select directly the commit you want to
submit.

Add option --commit to command 'git-p4 submit' in order to submit
only specified commit(s) in p4.

On a daily work developping software with big compilation time, one
may not want to rebase on his local git tree, in order to avoid long
recompilation.

Add option --disable-rebase to command 'git-p4 submit' in order to
disable rebase after submission.

e9502c0a7f fetch-pack: don't try to fetch peel values with --all
When "fetch-pack --all" sees a tag-to-blob on the remote, it
tries to fetch both the tag itself ("refs/tags/foo") and the
peeled value that the remote advertises ("refs/tags/foo^{}").
Asking for the object pointed to by the latter can cause
upload-pack to complain with "not our ref", since it does
not mark the peeled objects with the OUR_REF (unless they
were at the tip of some other ref).

Arguably upload-pack _should_ be marking those peeled
objects. But it never has in the past, since clients would
generally just ask for the tag and expect to get the peeled
value along with it. And that's how "git fetch" works, as
well as older versions of "fetch-pack --all".

The problem was introduced by 5f0fc64513 (fetch-pack:
eliminate spurious error messages, 2012-09-09). Before then,
the matching logic was something like:

  if (refname is ill-formed)
     do nothing
  else if (doing --all)
     always consider it matched
  else
     look through list of sought refs for a match

That commit wanted to flip the order of the second two arms
of that conditional. But we ended up with:

  if (refname is ill-formed)
    do nothing
  else
    look through list of sought refs for a match

  if (--all and no match so far)
    always consider it matched

That means tha an ill-formed ref will trigger the --all
conditional block, even though we should just be ignoring
it. We can fix that by having a single "else" with all of
the well-formed logic, that checks the sought refs and
"--all" in the correct order.

47cc91310a fsck: avoid looking at NULL blob->object
Commit 159e7b080b (fsck: detect gitmodules files,
2018-05-02) taught fsck to look at the content of
.gitmodules files. If the object turns out not to be a blob
at all, we just complain and punt on checking the content.
And since this was such an obvious and trivial code path, I
didn't even bother to add a test.

Except it _does_ do one non-trivial thing, which is call the
report() function, which wants us to pass a pointer to a
"struct object". Which we don't have (we have only a "struct
object_id"). So we erroneously pass a NULL object to
report(), which gets dereferenced and causes a segfault.

It seems like we could refactor report() to just take the
object_id itself. But we pass the object pointer along to
a callback function, and indeed this ends up in
builtin/fsck.c's objreport() which does want to look at
other parts of the object (like the type).

So instead, let's just use lookup_unknown_object() to get
the real "struct object", and pass that.

431acd2de8 t7415: don't bother creating commit for symlink test
Early versions of the fsck .gitmodules detection code
actually required a tree to be at the root of a commit for
it to be checked for .gitmodules. What we ended up with in
159e7b080b (fsck: detect gitmodules files, 2018-05-02),
though, finds a .gitmodules file in _any_ tree (see that
commit for more discussion).

As a result, there's no need to create a commit in our
tests. Let's drop it in the name of simplicity. And since
that was the only thing referencing $tree, we can pull our
tree creation out of a command substitution.

b221b5ab9b completion: collapse extra --no-.. options
The commands that make use of --git-completion-helper feature could
now produce a lot of --no-xxx options that a command can take. This in
many case could nearly double the amount of completable options, using
more screen estate and also harder to search for the wanted option.

This patch attempts to mitigate that by collapsing extra --no-
options, the ones that are added by --git-completion-helper and not in
original struct option arrays. The "--no-..." option will be displayed
in this case to hint about more options, e.g.

    > ~/w/git $ git clone --
    --bare                 --origin=
    --branch=              --progress
    --checkout             --quiet
    --config=              --recurse-submodules
    --depth=               --reference=
    --dissociate           --reference-if-able=
    --filter=              --separate-git-dir=
    --hardlinks            --shallow-exclude=
    --ipv4                 --shallow-since=
    --ipv6                 --shallow-submodules
    --jobs=                --shared
    --local                --single-branch
    --mirror               --tags
    --no-...               --template=
    --no-checkout          --upload-pack=
    --no-hardlinks         --verbose
    --no-tags

and when you complete it with --no-<tab>, all negative options will be
presented:

    > ~/w/git $ git clone --no-
    --no-bare                 --no-quiet
    --no-branch               --no-recurse-submodules
    --no-checkout             --no-reference
    --no-config               --no-reference-if-able
    --no-depth                --no-separate-git-dir
    --no-dissociate           --no-shallow-exclude
    --no-filter               --no-shallow-since
    --no-hardlinks            --no-shallow-submodules
    --no-ipv4                 --no-shared
    --no-ipv6                 --no-single-branch
    --no-jobs                 --no-tags
    --no-local                --no-template
    --no-mirror               --no-upload-pack
    --no-origin               --no-verbose
    --no-progress

Corner case: to make sure that people will never accidentally complete
the fake option "--no-..." there must be one real --no- in the first
complete listing even if it's not from the original struct option.

PS. This could could be made simpler with ";&" to fall through from
"--no-*" block and share the code but ";&" is not available on bash-3
(i.e. Mac)

2f3cbcd8c5 tests: make forging GPG signed commits and tags more robust
A couple of test scripts create forged GPG signed commits or tags to
check that such forgery can't fool various git commands' signature
verification.  All but one of those test scripts are prone to
occasional failures because the forgery creates a bogus GPG signature,
and git commands error out with an unexpected error message, e.g.
"Commit deadbeef does not have a GPG signature" instead of "...  has a
bad GPG signature".

't5573-pull-verify-signatures.sh', 't7510-signed-commit.sh' and
't7612-merge-verify-signatures.sh' create forged signed commits like
this:

  git commit -S -m "bad on side" &&
  git cat-file commit side-bad >raw &&
  sed -e "s/bad/forged bad/" raw >forged &&
  git hash-object -w -t commit forged >forged.commit

On rare occasions the given pattern occurs not only in the commit
message but in the GPG signature as well, and after it's replaced in
the signature the resulting signature becomes invalid, GPG will report
CRC error and that it couldn't find any signature, which will then
ultimately cause the test failure.

Since in all three cases the pattern to be replaced during the forgery
is the first word of the commit message's subject line, and since the
GPG signature in the commit object is indented by a space, let's just
anchor those patterns to the beginning of the line to prevent this
issue.

The test script 't7030-verify-tag.sh' creates a forged signed tag
object in a similar way by replacing the pattern "seventh", but the
GPG signature in tag objects is not indented by a space, so the above
solution is not applicable in this case.  However, in the tag object
in question the pattern "seventh" occurs not only in the tag message
but in the 'tag' header as well.  To create a forged tag object it's
sufficient to replace only one of the two occurences, so modify the
sed script to limit the pattern to the 'tag' header (i.e. a line
beginning with "tag ", which, because of the space character, can
never occur in the base64-encoded GPG signature).

Note that the forgery in 't7004-tag.sh' is not affected by this issue:
while 't7004' does create a forged signed tag kind of the same way,
it replaces "signed-tag" in the tag object, which, because of the '-'
character, can never occur in the base64-encoded GPG signarute.

9dd39821e3 t7510-signed-commit: use 'test_must_fail'
The two tests 'detect fudged signature' and 'detect fudged signature
with NUL' in 't7510-signed-commit.sh' check that 'git verify-commit'
errors out when encountering a forged commit, but they do so by
running

  ! git verify-commit ...

Use 'test_must_fail' instead, because that would catch potential
unexpected errors like a segfault as well.
