Just because the files backend can't retain reflogs for deleted
references is no reason that they shouldn't be supported by the
virtual method interface. Also, `delete_ref()` and `refs_delete_ref()`
have already gained `msg` parameters. Now let's add them to
`delete_refs()` and `refs_delete_refs()`.

The test of failing `git rm -f` removes the write permissions on the
test directory, but fails to restore them if the test fails. This
means that the test temporary directory cannot be cleaned up, which
means that subsequent attempts to run the test fail mysteriously.
Instead, do the cleanup in a `test_when_finished` block so that it
can't be skipped.

Convert parse_tree_indirect to take a pointer to struct object_id.

Update tests to pass under GETTEXT_POISON (a mechanism to ensure

The GETTEXT_POISON=YesPlease compile-time testing option added in my
bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly
translator", 2011-02-22) has been slowly bitrotting as strings have
been marked for translation, and new tests have been added without
running it.
I brought this up on the list ("[BUG] test suite broken with
GETTEXT_POISON=YesPlease", [1]) asking whether this mode was useful at
all anymore. At least one person occasionally uses it, and Lars
Schneider offered to change one of the the Travis builds to run in
this mode, so fix up the failing ones.
My test setup runs most of the tests, with the notable exception of
skipping all the p4 tests, so it's possible that there's still some
lurking regressions I haven't fixed.

t0027: tests are not expensive; remove t0025

The purpose of t0027 is to test all CRLF related conversions at "git
checkout" and "git add". Running t0027 under Git for Windows takes
3-4 minutes, so the whole script had been marked as "EXPENSIVE".
However, the "Git for Windows" fork overrides this since 2014:
"t0027 is marked expensive, but really, for MinGW we want to run
these tests always."
The test seems not to be expensive on other platforms at all: it
takes less than 14 seconds under Linux, and 63 seconds under Mac Os
X, and this is more or less the same with a SSD or a spinning disk.
So let's drop the "EXPENSIVE" prereq.
While at it, retire t0025; recent "stress" tests show that t0025 is
flaky, reported by Lars Schneider <larsxschneider@gmail.com>, but
all tests in t0025 are covered by t0027 already.

The receive-pack program now makes sure that the push certificate

In commit f6a4e61 ("push: accept push options", 2016-07-14), send-pack
was taught to include push options both within the signed cert (if the
push is a signed push) and outside the signed cert; however,
receive-pack ignores push options within the cert, only handling push
options outside the cert.
Teach receive-pack, in the case that push options are provided for a
signed push, to verify that the push options both within the cert and
outside the cert are consistent.
This sets in stone the requirement that send-pack redundantly send its
push options in 2 places, but I think that this is better than the
alternatives. Sending push options only within the cert is
backwards-incompatible with existing Git servers (which read push
options only from outside the cert), and sending push options only
outside the cert means that the push options are not signed for.

The recent change that introduced autodecorating of refs accidentally
broke the ability of users to set log.decorate = false to override it.
When the git_log_config was traversed a second time with an option other
than log.decorate, the decoration style would be set to the automatic
style, even if the user had already overridden it. Instead of setting
the option in config parsing, set it in init_log_defaults instead.
Add a test for this case. The actual additional config option doesn't
matter, but it needs to be something not already set in the
configuration file.

Commit cf9e55f494 ("submodule: prevent backslash expantion in submodule
names", 07-04-2017) added a test which creates a git repository with
some backslash characters in the name. On windows, where the backslash
character is a directory separator, it is not possible to create a
repository with the name 'sub\with\backslash'. (The NTFS filesystem would
probably allow it, but the win32 api does not). The MinGW and Git for
Windows versions of git actually create a repository called 'backslash'
in the sub-directory 'sub/with'.
On cygwin, however, due to the slightly schizophrenic treatment of the
backslash character by cygwin-git, this test fails at the 'git init'
stage. The git-init command does not recognise the directory separators
in the input path (eg. is_dir_sep('\\') is false), so it does not
attempt to create the leading directories 'sub/with'. (The call to
mkdir('sub\\with\\backslash') actually does recognise the directory
separators, but fails because the 'sub/with' directory doesn't exist).
In order to suppress the test failure (for now), add the !CYGWIN test
prerequisite.

Some platforms have ulong that is smaller than time_t, and our
historical use of ulong for timestamp would mean they cannot
represent some timestamp that the platform allows. Invent a
separate and dedicated timestamp_t (so that we can distingiuish
timestamps and a vanilla ulongs, which along is already a good
move), and then declare uintmax_t is the type to be used as the
timestamp_t.

Git's source code assumes that unsigned long is at least as precise as
time_t. Which is incorrect, and causes a lot of problems, in particular
where unsigned long is only 32-bit (notably on Windows, even in 64-bit
versions).
So let's just use a more appropriate data type instead. In preparation
for this, we introduce the new `timestamp_t` data type.
By necessity, this is a very, very large patch, as it has to replace all
timestamps' data type in one go.
As we will use a data type that is not necessarily identical to `time_t`,
we need to be very careful to use `time_t` whenever we interact with the
system functions, and `timestamp_t` everywhere else.

Currently, Git's source code treats all timestamps as if they were
unsigned longs. Therefore, it is okay to write "%lu" when printing them.
There is a substantial problem with that, though: at least on Windows,
time_t is *larger* than unsigned long, and hence we will want to switch
away from the ill-specified `unsigned long` data type.
So let's introduce the pseudo format "PRItime" (currently simply being
defined to "lu") to make it easier to change the data type used for
timestamps.

Currently, Git's source code represents all timestamps as `unsigned
long`. In preparation for using a more appropriate data type, let's
introduce a symbol `parse_timestamp` (currently being defined to
`strtoul`) where appropriate, so that we can later easily switch to,
say, use `strtoull()` instead.

Git's source code refers to timestamps as unsigned long, which is
ill-defined, as there is no guarantee about the number of bits that
data type has.
In preparation of switching to another data type that is large enough
to hold "far in the future" dates, we need to prepare the t0006-date.sh
script for the case where we *still* cannot format those dates if the
system library uses 32-bit time_t.

Git's source code refers to timestamps as unsigned longs. On 32-bit
platforms, as well as on Windows, unsigned long is not large enough to
capture dates that are "absurdly far in the future".
It is perfectly valid by the C standard, of course, for the `long` data
type to refer to 32-bit integers. That is why the `time_t` data type
exists: so that it can be 64-bit even if `long` is 32-bit. Git's source
code simply uses an incorrect data type for timestamps, is all.
The earlier quick fix 6b9c38e14cd (t0006: skip "far in the future" test
when unsigned long is not long enough, 2016-07-11) papered over this
issue simply by skipping the respective test cases on platforms where
they would fail due to the data type in use.
This quick fix, however, tests for *long* to be 64-bit or not. What we
need, though, is a test that says whether *whatever data type we use for
timestamps* is 64-bit or not.
The same quick fix was used to handle the similar problem where Git's
source code uses `unsigned long` to represent size, instead of `size_t`,
conflating the two issues.
So let's just add another prerequisite to test specifically whether
timestamps are represented by a 64-bit data type or not. Later, after we
switch to a larger data type, we can flip that prerequisite to test
`time_t` instead of `long`.

"git clone --config" uses the following incantation to add an item to
a config file, instead of replacing an existing value:
git_config_set_multivar_gently(key, value, "^$", 0)
As long as no existing value matches the regex ^$, that works as
intended and adds to the config. When a value is empty, though, it
replaces the existing value.
Noticed while trying to set credential.helper during a clone to use a
specific helper without inheriting from ~/.gitconfig and
/etc/gitconfig. That is, I ran
git clone -c credential.helper= \
-c credential.helper=myhelper \
https://example.com/repo
intending to produce the configuration
[credential]
helper =
helper = myhelper
Without this patch, the 'helper =' line is not included and the
credential helper from /etc/gitconfig gets used.

Write a zip64 extended information extra field for big files as part of
their local headers and as part of their central directory headers.
Also write a zip64 version of the data descriptor in that case.
If we're streaming then we don't know the compressed size at the time we
write the header. Deflate can end up making a file bigger instead of
smaller if we're unlucky. Write a local zip64 header already for files
with a size of 2GB or more in this case to be on the safe side.
Both sizes need to be included in the local zip64 header, but the extra
field for the directory must only contain 64-bit equivalents for 32-bit
values of 0xffffffff.

Test the creation of ZIP archives bigger than 4GB and containing files
bigger than 4GB. They are marked as EXPENSIVE because they take quite a
while and because the first one needs a bit more than 4GB of disk space
to store the resulting archive.
The big archive in the first test is made up of a tree containing
thousands of copies of a small file. Yet the test has to write out the
full archive because unzip doesn't offer a way to read from stdin.
The big file in the second test is provided as a zipped pack file to
avoid writing another 4GB file to disk and then adding it.

Add a --no-tags option to clone without fetching any tags.
Without this change there's no easy way to clone a repository without
also fetching its tags.
When supplying --single-branch the primary remote branch will be
cloned, but in addition tags will be followed & retrieved. Now
--no-tags can be added --single-branch to clone a repository without
tags, and which only tracks a single upstream branch.
This option works without --single-branch as well, and will do a
normal clone but not fetch any tags.
Many git commands pay some fixed overhead as a function of the number
of references. E.g. creating ~40k tags in linux.git will cause a
command like `git log -1 >/dev/null` to run in over a second instead
of in a matter of milliseconds, in addition numerous other things will
slow down, e.g. "git log <TAB>" with the bash completion will slowly
show ~40k references instead of 1.
The user might want to avoid all of that overhead to simply use a
repository like that to browse the "master" branch, or something like
a CI tool might want to keep that one branch up-to-date without caring
about any other references.
Without this change the only way of accomplishing this was either by
manually tweaking the config in a fresh repository:
git init git &&
cat >git/.git/config <<EOF &&
[remote "origin"]
url = git@github.com:git/git.git
tagOpt = --no-tags
fetch = +refs/heads/master:refs/remotes/origin/master
[branch "master"]
remote = origin
merge = refs/heads/master
EOF
cd git &&
git pull
Which requires hardcoding the "master" name, which may not be the main
--single-branch would have retrieved, or alternatively by setting
tagOpt=--no-tags right after cloning & deleting any existing tags:
git clone --single-branch git@github.com:git/git.git &&
cd git &&
git config remote.origin.tagOpt --no-tags &&
git tag -l | xargs git tag -d
Which of course was also subtly buggy if --branch was pointed at a
tag, leaving the user in a detached head:
git clone --single-branch --branch v2.12.0 git@github.com:git/git.git &&
cd git &&
git config remote.origin.tagOpt --no-tags &&
git tag -l | xargs git tag -d
Now all this complexity becomes the much simpler:
git clone --single-branch --no-tags git@github.com:git/git.git
Or in the case of cloning a single tag "branch":
git clone --single-branch --branch v2.12.0 --no-tags git@github.com:git/git.git

When git-status shows tracking data for the current branch
in the long format, we try to end the stanza with a blank
line. When status.displayCommentPrefix is true, we call
color_fprintf_ln() to do so. But when it's false, we call
the enigmatic:
fputs("", s->fp);
which does nothing at all! This is a bug from 7d7d68022
(silence a bunch of format-zero-length warnings,
2014-05-04). Prior to that, we called fprintf_ln() with an
empty string. Switching to fputs() meant we needed to
include the "newline in the string, but we didn't.
So you see:
On branch jk/status-tracking-newline
Your branch is ahead of 'origin/master' by 1 commit.
Changes not staged for commit:
modified: foo
Untracked files:
bar
whereas there should be a blank line before the "Changes not
staged" line.
The fix itself is a one-liner. But we never noticed this
bug because t7508 doesn't exercise the ahead/behind code at
all. So let's configure an upstream during the initial
setup, which means that the code will be exercised as part
of all of the various invocations in that script. This makes
the diff rather noisy, but should give us good coverage.

When encountering a commit message that does not end in a newline,
sequencer does not complete the line before determining if a blank line
should be added. This causes the "(cherry picked..." and sign-off lines
to sometimes appear on the same line as the last line of the commit
message.
This behavior was introduced by commit 967dfd4 ("sequencer: use
trailer's trailer layout", 2016-11-29). However, a revert of that commit
would not resolve this issue completely: prior to that commit, a
conforming footer was deemed to be non-conforming by
has_conforming_footer() if there was no terminating newline, resulting
in both conforming and non-conforming footers being treated the same
when they should not be.
Resolve this issue, both for conforming and non-conforming footers, and
in both do_pick_commit() and append_signoff(), by always adding a
newline to the commit message if it does not end in one before checking
the footer for conformity.

added this function in order to update HEADs of all relevant

It, as a public ref api, kind of breaks abstraction when it uses
internal functions of files backend. With the introduction of

70999e9cec, where create_symref() was used for updating HEAD.

The convention "$remove_trash is set to the trash directory that is
used during the test, so that it will be removed at the end, but
under --debug option we set the varilable to empty string to
preserve the directory" made sense back when it was introduced, as
there was no $TRASH_DIRECTORY variable. These days, since no tests
looks at the variable, it is obscure and even risks that by mistake
the variable gets used for something else (e.g. remove_trash=yes)
and cause us misbehave. Worse yet, remove_trash was not initialized
to an empty string at the beginning, so a stray environment variable
the user has could have affected the logic when "--debug" is in use.
Rewrite the clean-up sequence in test_done helper to explicitly
check the $debug condition and remove the trash directory using
the $TRASH_DIRECTORY variable.
Note that "go to the directory one level above the trash and then
remove it" is kept and this is deliverate; test_at_end_hook_ will
keep running from the expected location, and also some platforms may
not like a directory that is serving as the $cwd of a still-active
process removed.

The original did "does $remove_trash exist? Then go one level above
and remove it". There was no problem under "--debug", where
the variable is left empty, as the first "test -d $remove_trash" would
have said "No, it doesn't".
With the check implemented in the previous step, we'd always get an
error under "--debug".

We had two similar bugs in the tests sporadically triggering error
messages during the removal of the trash directory, see commits
bb05510e5 (t5510: run auto-gc in the foreground, 2016-05-01) and
ef09036cf (t6500: wait for detached auto gc at the end of the test
script, 2017-04-13). The test script succeeded nonetheless, because
these errors are ignored during housekeeping in 'test_done'.
However, such an error is a sign that something is fishy in the test
script. Print an error message and abort the test script when the
trash directory can't be removed successfully or is already removed,
because that's unexpected and we would prefer somebody notice and
figure out why.

We generally disallow null sha1s from entering the index,
due to 4337b5856 (do not write null sha1s to on-disk index,
2012-07-28). However, we loosened that in 83bd7437c
(write_index: optionally allow broken null sha1s,
2013-08-27) so that tools like filter-branch could be used
to repair broken history.
However, we should make sure that these broken entries do
not get propagated into new trees. For most entries, we'd
catch them with the missing-object check (since presumably
the null sha1 does not exist in our object database). But
gitlink entries do not need reachability, so we may blindly
copy the entry into a bogus tree.
This patch rejects all null sha1s (with the same "invalid
entry" message that missing objects get) when building trees
from the index. It does so even for non-gitlinks, and even
when "write-tree" is given the --missing-ok flag. The null
sha1 is a special sentinel value that is already rejected in
trees by fsck; whether the object exists or not, it is an
error to put it in a tree.
Note that for this to work, we must also avoid reusing an
existing cache-tree that contains the null sha1. This patch
does so by just refusing to write out any cache tree when
the index contains a null sha1. This is blunter than we need
to be; we could just reject the subtree that contains the
offending entry. But it's not worth the complexity. The
behavior is unchanged unless you have a broken index entry,
and even then we'd refuse the whole index write unless the
emergency GIT_ALLOW_NULL_SHA1 is in use. And even then the
end result is only a performance drop (any write-tree will
have to generate the whole cache-tree from scratch).
The tests bear some explanation.
The existing test in t7009 doesn't catch this problem,
because our index-filter runs "git rm --cached", which will
try to rewrite the updated index and barf on the bogus
entry. So we never even make it to write-tree. The new test
there adds a noop index-filter, which does show the problem.
The new tests in t1601 are slightly redundant with what
filter-branch is doing under the hood in t7009. But as
they're much more direct, they're easier to reason about.
And should filter-branch ever change or go away, we'd want
to make sure that these plumbing commands behave sanely.

t1450: avoid use of "sed" on the index, which is a binary file

The previous step added a path zzzzzzzz to the index, and then used
"sed" to replace this string to yyyyyyyy to create a test case where
the checksum at the end of the file does not match the contents.
Unfortunately, use of "sed" on a non-text file is not portable.
Instead, use a Perl script that seeks to the end and modifies the
last byte of the file (where we _know_ stores the trailing
checksum).
