Make git checkout (and other unpack_tree operations) preserve the
untracked cache. This is valuable for two reasons:
1. Often, an unpack_tree operation will not touch large parts of the
working tree, and thus most of the untracked cache will continue to be
valid.
2. Even if the untracked cache were entirely invalidated by such an
operation, the user has signaled their intention to have such a cache,
and we don't want to throw it away.

The shell version of rebase -i silences the status output from 'git
stash apply' when restoring the autostashed changes. The C version
does not.
Having the output from git stash apply on the screen is
distracting as it makes it difficult to find the message from git
rebase saying that the rebase succeeded. Also the status information
that git stash prints talks about looking in .git/rebase-merge/done to
see which commits have been applied. As .git/rebase-merge is removed
shortly after the message is printed before rebase -i exits this is

ref-filter: resolve HEAD when parsing %(HEAD) atom
If the user asks to display (or sort by) the %(HEAD) atom,
ref-filter has to compare each refname to the value of HEAD.
We do so by resolving HEAD fresh when calling populate_value()
on each ref. If there are a large number of refs, this can
have a measurable impact on runtime.
Instead, let's resolve HEAD once when we realize we need the
%(HEAD) atom, allowing us to do a simple string comparison
for each ref. On a repository with 3000 branches (high, but
an actual example found in the wild) this drops the
best-of-five time to run "git branch >/dev/null" from 59ms
to 48ms (~20% savings).

Earlier dddbad72 ("timestamp_t: a new data type for timestamps",
2017-04-26) updated all in-core variables, fields and function
return values that are used to store "seconds since epoch" to a new
type timestamp_t. Unfortunately one variable "cutoff", which is
used to keep track of the oldest timestamp of commit we saw on the
command line, was "long" and left behind.
If a commit message is edited with the "verbose" option, the buffer
will have a cut line and diff after the log message, like so:
my subject
# ------------------------ >8 ------------------------
# Do not touch the line above.
# Everything below will be removed.
diff --git a/foo.txt b/foo.txt
index 5716ca5..7601807 100644
--- a/foo.txt
+++ b/foo.txt
@@ -1 +1 @@
-bar
+baz
"git interpret-trailers" is unaware of the cut line, and assumes the
trailer block would be at the end of the whole thing. This can easily
be seen with:
Teach "git interpret-trailers" to notice the cut-line and ignore the
remainder of the input when looking for a place to add new trailer
block. This makes it consistent with how "git commit -v -s" inserts a
new Signed-off-by: line.
This can be done by the same logic as the existing helper function,
wt_status_truncate_message_at_cut_line(), uses, but it wants the caller
to pass a strbuf to it. Because the function ignore_non_trailer() used
by the command takes a <pointer, length> pair, not a strbuf, steal the
logic from wt_status_truncate_message_at_cut_line() to create a new
wt_status_locate_end() helper function that takes <pointer, length>
pair, and make ignore_non_trailer() call it to help "interpret-trailers".
Since there is only one caller of wt_status_truncate_message_at_cut_line()
in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead
and remove the old helper that no longer has any caller.

One test in t5400 examines the packet exchange between git-push and
git-receive-pack. The latter inherits the GIT_TRACE_PACKET environment
variable, so that both processes dump trace data into the same file
concurrently. This should not be a problem because the trace file is
opened with O_APPEND.
On Windows, however, O_APPEND is not atomic as it should be: it is
emulated as lseek(SEEK_END) followed by write(). For this reason, the
test is unreliable: it can happen that one process overwrites a line
that was just written by the other process. As a consequence, the test
sometimes does not find one or another line that is expected (and it is
also successful occasionally).
The test case is actually only interested in the output of git-push.
To ensure that only git-push writes to the trace file, override the
receive-pack command such that it does not even open the trace file.

config: complain about --local outside of a git repo
The "--local" option instructs git-config to read or modify
the repository-level config. This doesn't make any sense if
you're not actually in a repository.
Older versions of Git would blindly try to read or write
".git/config". For reading, this would result in a quiet
failure, since there was no config to read (and thus no
matching config value). Writing would generally fail
noisily, since ".git" was unlikely to exist. But since b1ef400ee (setup_git_env: avoid blind fall-back to ".git",
2016-10-20), we catch this in the call to git_pathdup() and
die with an assertion.
Dying is the right thing to do, but we should catch the
problem early and give a more human-friendly error message.
Note that even without --local, git-config will sometimes
default to using local repository config (e.g., when
writing). These cases are already protected by similar
checks, and covered by a test in t1308.

Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
There's a convention in Git's code base to write assertions
as:
if (...some_bad_thing...)
die("BUG: the terrible thing happened");
with the idea that users should never see a "BUG:" message
(but if they, it at least gives a clue what happened). We
use die() here because it's convenient, but there are a few
draw-backs:
1. Without parsing the messages, it's hard for callers to
distinguish BUG assertions from regular errors.
For instance, it would be nice if the test suite could
check that we don't hit any assertions, but
test_must_fail will pass BUG deaths as OK.
2. It would be useful to add more debugging features to
BUG assertions, like file/line numbers or dumping core.
3. The die() handler can be replaced, and might not
actually exit the whole program (e.g., it may just
pthread_exit()). This is convenient for normal errors,
but for an assertion failure (which is supposed to
never happen), we're probably better off taking down
the whole process as quickly and cleanly as possible.
We could address these by checking in die() whether the
error message starts with "BUG", and behaving appropriately.
But there's little advantage at that point to sharing the
die() code, and only downsides (e.g., we can't change the
BUG() interface independently). Moreover, converting all of
the existing BUG calls reveals that the test suite does
indeed trigger a few of them.
Instead, this patch introduces a new BUG() function, which
prints an error before dying via SIGABRT. This gives us test
suite checking and core dumps. The function is actually a
macro (when supported) so that we can show the file/line
number.
We can convert die("BUG") invocations to BUG() in further
patches, dealing with any test fallouts individually.

usability: don't ask questions if no reply is required
There has been a bug report by a corporate user that stated that
"spelling mistake of stash followed by a yes prints character 'y'
infinite times."
This analysis was false. When the spelling of a command contains
errors, the git program tries to help the user by providing candidates
which are close to the unexisting command. E.g Git prints the
following:
git: 'stahs' is not a git command. See 'git --help'.
Did you mean this?
stash
and then exits.
The problem with this hint is that it is not formally indicated as an
hint and the user is in fact encouraged to reply to the question,
whereas the Git command is already finished.
The user was unlucky enough that it was the command he was looking
for, and replied "yes" on the command line, effectively launching the
`yes` program.
The initial error is that the Git programs, when launched in
command-line mode (without interaction) must not ask questions,
because these questions would normally require a user input as a reply
that they won't handle indeed. That's a source of confusion on UX
level.
To improve the general usability of the Git suite, the following rule
was applied:
if the sentence
* appears in a non-interactive session
* is printed last before exit
* is a question addressing the user ("you")
the sentence is turned into affirmative and proposes the option.
The basic rewording of the question sentences has been extended to
other spots found in the source.

trailing slash 'prune_cache()' will be overeager and prune a submodule
'sub' if the common prefix is 'sub/'. To correct this behavior, only
prune entries which don't match up to, but not including, a trailing
slash of the common prefix.

verbatim insertion. And it can cause confusion with the
expanding of the path itself via things like "~".
Let's clarify when we are referring to the contents versus
the filename, and use appropriate verbs in each case.

travis-ci: add job to run tests with GETTEXT_POISON
Add a job to run Git tests with GETTEXT_POISON. In this job we don't run
the git-p4, git-svn, and HTTPD tests to save resources/time (those tests
are already executed in other jobs). Since we don't run these tests, we
can also skip the "before_install" step (which would install the
necessary dependencies) with an empty override.

The command that made the "prove cache" persistent across builds was
executed in the "before_install" step. Consequently, every job that
wanted to make use of the cache had to run this step.
The "prove cache" is only used in the "script" step for the
"make test" command. Therefore, we should configure the "prove cache"
in this step.
This change is useful for a subsequent patch that adds a job which does
not need the "before_install" step but wants to run the "script" step to
execute the tests.

tests: fix tests broken under GETTEXT_POISON=YesPlease
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

I brought this up on the list ("[BUG] test suite broken with

all anymore. At least one person occasionally uses it, and Lars
Schneider offered to change one of the the Travis builds to run in

read-tree: "read-tree -m --empty" does not make sense
fb1bb965 ("read-tree: deprecate syntax without tree-ish args",
2010-09-10) wanted to deprecate "git read-tree" without any tree,
which used to be the way to empty the index, and encourage use of
"git read-tree --empty" instead.
However, when used with "-m", "--empty" does not make any sense,
either, simply because merging 0 trees will result in a different
error anyway.
Omit the deprecation warning and let the code to emit real error
message diagnose the error.
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.

t4051: mark supporting files as requiring LF-only line endings
The test t4051-diff-function-context.sh passes on Linux when
core.autocrlf=true even without marking its support files as LF-only,
but they fail when core.autocrlf=true in Git for Windows' SDK.
The reason is that `grep ... >file.c.new` will keep CR/LF line endings
on Linux (obviously treating CRs as if they were regular characters),
but will be converted to LF-only line endings with MSYS2's grep that is
used in Git for Windows.
As we do not want to validate the way the available `grep` works, let's
just mark the input as LF-only and move on.

Fix the remaining tests that failed with core.autocrlf=true
The test suite is mainly developed on Linux and MacOSX, which is the
reason that nobody thought to mark files as LF-only as needed.
The symptom is a test suite that fails left and right when being checked
out using Git for Windows (which defaults to core.autocrlf=true).
Mostly, the problems stem from Git's (LF-only) output being compared to
hard-coded files that are checked out with line endings according to
core.autocrlf (which is of course incorrect). This includes the two test
files in t/diff-lib/, README and COPYING.
This patch can be validated even on Linux by using this cadence:
git config core.autocrlf true

On Windows, the default line endings are denoted by a Carriage Return
byte followed by a Line Feed byte, while Linux and MacOSX use a single
Line Feed byte to denote a line ending.
To help with this situation, Git introduced several mechanisms over the
last decade, most prominently the `core.autocrlf` setting.
Sometimes, however, a single setting is incorrect, e.g. when certain
files in the source code are to be consumed by software that can handle
only LF line endings, while other files can use whatever is appropriate
for the current platform.
To allow for that, Git added the `eol` option to its .gitattributes
handling, expecting every user of Git to mark their source code
appropriately.
Bash assumes that line-endings of scripts are denoted by a single Line
Feed byte. Therefore, shell scripts in Git's source code are one example
where that `eol=lf` option is *required*.
When generating common-cmds.h, the Unix tools we use generally operate on
the assumption that input and output deliminate their lines using LF-only
line endings. Consequently, they would happily copy the CR byte verbatim
into the strings in common-cmds.h, which in turn makes the C preprocessor
barf (that interprets them as MacOS-style line endings). Therefore, we
have to mark the input files as LF-only: command-list.txt and
Documentation/git-*.txt.
Quite a bit belatedly, this patch brings Git's own source code in line
with those expectations by setting those attributes to allow for a
correct build even when core.autocrlf=true.
This patch can be validated even on Linux, by using this cadence:

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.

pack-objects: disable pack reuse for object-selection options
If certain options like --honor-pack-keep, --local, or
--incremental are used with pack-objects, then we need to
feed each potential object to want_object_in_pack() to see
if it should be filtered out. But when the bitmap
reuse_packfile optimization is in effect, we do not call
that function at all, and in fact skip adding the objects to
the to_pack list entirely. This means we have a bug: for
certain requests we will silently ignore those options and
include objects in that pack that should not be there.
The problem has been present since the inception of the
pack-reuse code in 6b8fda2db (pack-objects: use bitmaps when
packing objects, 2013-12-21), but it was unlikely to come up
in practice. These options are generally used for on-disk
packing, not transfer packs (which go to stdout), but we've
never allowed pack reuse for non-stdout packs (until 645c432d6, we did not even use bitmaps, which the reuse
optimization relies on; after that, we explicitly turned it
off when not packing to stdout).
We can fix this by just disabling the reuse_packfile
optimization when the options are in use. In theory we could
teach the pack-reuse code to satisfy these checks, but it's
not worth the complexity. The purpose of the optimization is
to keep the amount of per-object work we do to a minimum.
But these options inherently require us to search for other
copies of each object, drowning out any benefit of the
pack-reuse optimization. But note that the optimizations
from 56dfeb626 (pack-objects: compute local/ignore_pack_keep
early, 2016-07-29) happen before pack-reuse, meaning that
specifying "--honor-pack-keep" in a repository with no .keep
files can still follow the fast path.
There are tests in t5310 that check these options with
bitmaps and --stdout, but they didn't catch the bug, and
it's hard to adapt them to do so.
One problem is that they don't use --delta-base-offset;
without that option, we always disable the reuse
optimization entirely. It would be fine to add it in (it
actually makes the test more realistic), but that still
isn't quite enough.
The other problem is that the reuse code is very picky; it
only kicks in when it can reuse most of a pack, starting
from the first byte. So we'd have to start from a fully
repacked and bitmapped state to trigger it. But the tests
for these options use a much more subtle state; they want to
be sure that the want_object_in_pack() code is allowing some
objects but not others. Doing a full repack runs counter to
that.
So this patch adds new tests at the end of the script which
create the fully-packed state and make sure that each option
is not fooled by reusable pack.

archive-tar: fix a sparse 'constant too large' warning
Commit dddbad728c ("timestamp_t: a new data type for timestamps",
26-04-2017) introduced a new typedef 'timestamp_t', as a synonym for an
unsigned long, which was used at the time to represent timestamps in
git. A later commit 28f4aee3fb ("use uintmax_t for timestamps",
26-04-2017) changed the typedef to use an 'uintmax_t' for the timestamp
representation type.
When building on a 32-bit Linux system, sparse complains that a constant
(USTAR_MAX_MTIME) used to detect a 'far-future mtime' timestamp, is too
large; 'warning: constant 077777777777UL is so big it is unsigned long
long' on lines 335 and 338 of archive-tar.c. Note that both gcc and
clang only issue a warning if this constant is used in a context that
requires an 'unsigned long' (rather than an uintmax_t). (Since TIME_MAX
is no longer equal to 0xFFFFFFFF, even on a 32-bit system, the macro
USTAR_MAX_MTIME is set to 077777777777UL, which cannot be represented as
an 'unsigned long' constant).
In order to suppress the warning, change the definition of the macro
constant USTAR_MAX_MTIME to use an 'ULL' type suffix.
In a similar vein, on systems which use a 64-bit representation of the
'unsigned long' type, the USTAR_MAX_SIZE constant macro is defined with
the value 077777777777ULL. Although this does not cause any warning
messages to be issued, it would be more appropriate for this constant
to use an 'UL' type suffix rather than 'ULL'.
