The filter_data used in the list-objects-filter (which manages a

Johannes Schindelin b09364c47a clean: show an error message when the path is too long
When `lstat()` failed, `git clean` would abort without an error
message, leaving the user quite puzzled.

In particular on Windows, where the default maximum path length is
quite small (yet there are ways to circumvent that limit in many
cases), it is very important that users be given an indication why
their command failed because of too long paths when it did.

This test case makes sure that a warning is issued that would have
helped the user who reported this issue:

	https://github.com/git-for-windows/git/issues/521

Note that we temporarily set `core.longpaths = false` in the regression
test; this ensures forward-compatibility with the `core.longpaths`
feature that has not yet been upstreamed from Git for Windows.

Junio C Hamano b2b1f615ce rm: resolving by removal is not a warning-worthy event
When resolving a conflict on a path in favor of removing it, using
"git rm" on it is the standard way to do so.  The user however is
greeted with a "needs merge" message during that operation:

	$ git merge side-branch
	$ edit conflicted-path-1
	$ git add conflicted-path-1
	$ git rm conflicted-path-2
	conflicted-path-2: needs merge
	rm 'conflicted-path-2'

The removal by "git rm" does get performed, but an uninitiated user
may find it confusing, "needs merge? so I need to resolve conflict
before being able to remove it???"

The message is coming from "update-index --refresh" that is called
internally to make sure "git rm" knows which paths are clean and
which paths are dirty, in order to prevent removal of paths modified
relative to the index without the "-f" option.  We somehow ended up
not squelching this message which seeped through to the UI surface.

Use the same mechanism used by "git commit", "git describe", etc. to
squelch the message.

Johannes Schindelin eb7c786314 mingw: support spawning programs containing spaces in their names
On some older Windows versions (e.g. Windows 7), the CreateProcessW()
function does not really support spaces in its first argument,
lpApplicationName. But it supports passing NULL as lpApplicationName,
which makes it figure out the application from the (possibly quoted)
first argument of lpCommandLine.

Let's use that trick (if we are certain that the first argument matches
the executable's path) to support launching programs whose path contains
spaces.

We will abuse the test-fake-ssh.exe helper to verify that this works and
does not regress.

Varun Naik 02638d1e11 read-cache.c: do not die if mmap fails
do_read_index() mmaps the index, or tries to die with an error message
on failure. It should call xmmap_gently(), which returns MAP_FAILED,
rather than xmmap(), which dies with its own error message.

An easy way to cause this mmap to fail is by setting $GIT_INDEX_FILE to
a path to a directory and then invoking any command that reads from the
index.

Emily Shaffer 3bca1e7f9f transport-helper: enforce atomic in push_refs_with_push
Teach transport-helper how to notice if skipping a ref during push would
violate atomicity on the client side. We notice that a ref would be
rejected, and choose not to send it, but don't notice that if the client
has asked for --atomic we are violating atomicity if all the other
pushes we are sending would succeed. Asking the server end to uphold
atomicity wouldn't work here as the server doesn't have any idea that we
tried to update a ref that's broken.

The added test-case is a succinct way to reproduce this issue that fails
today. The same steps work fine when we aren't using a transport-helper
to get to the upstream, i.e. when we've added a local repository as a
remote:

  git remote add ~/upstream upstream

Johannes Schindelin 3aef54e8b8 diff: munmap() file contents before running external diff
When running an external diff from, say, a diff tool, it is safe to
assume that we want to write the files in question. On Windows, that
means that there cannot be any other process holding an open handle to
said files, or even just a mapped region.

So let's make sure that `git diff` itself is not holding any open handle
to the files in question.

In fact, we will just release the file pair right away, as the external
diff uses the files we just wrote, so we do not need to hold the file
contents in memory anymore.

SZEDER Gábor af8ed04778 ci: disable Homebrew's auto cleanup
Lately Homebrew learned to automagically clean up information about
outdated packages during other 'brew' commands, which might be useful
for the avarage user, but is a waste of time in CI build jobs, because
the next build jobs will start from the exact same image containing
the same outdated packages anyway.

Export HOMEBREW_NO_INSTALL_CLEANUP=1 to disable this auto cleanup feature,
shaving off about 20-30s from the time needed to install dependencies
in our macOS build jobs on Travis CI.

SZEDER Gábor f2f4715033 ci: don't update Homebrew
Lately our GCC macOS build job on Travis CI has been erroring out
while installing dependencies with:

  +brew link gcc@8
  Error: No such keg: /usr/local/Cellar/gcc@8
  The command "ci/install-dependencies.sh" failed and exited with 1 during .

Now, while gcc@8 is still pre-installed (but not linked) and would be
perfectly usable in the Travis CI macOS image we use [1], it's at
version 8.2.  However, when installing dependencies we first
explicitly run 'brew update', which spends over two minutes to update
itself and information about the available packages, and it learns
about GCC 8.3.  After that point gcc@8 exclusively refers to v8.3,
and, unfortunately, 'brew' is just too dumb to be able to do anything
with the still installed 8.2 package, and the subsequent 'brew link
gcc@8' fails.  (Even 'brew uninstall gcc@8' fails with the same
error!)

Don't run 'brew update' to keep the already installed GCC 8.2 'brew
link'-able.  Note that in addition we have to 'export
HOMEBREW_NO_AUTO_UPDATE=1' first, because 'brew' is so very helpful
that it would implicitly run update for us on the next 'brew install
<pkg>' otherwise.

Disabling 'brew update' has additional benefits:

  - It shaves off 2-3mins from the ~4mins currently spent on
    installing dependencies, and the macOS build jobs have always been
    prone to exceeding the time limit on Travis CI.

  - Our builds won't suddenly break because of the occasional Homebrew
    breakages [2].

The drawback is that we'll be stuck with slightly older versions of
the packages that we install via Homebrew (Git-LFS 2.5.2 and Perforce
2018.1; they are currently at 2.7.2 and 2019.1, respectively).  We
might want to reconsider this decision as time goes on and/or switch
to a more recent macOS image as they become available.

SZEDER Gábor 5b12e3123b progress: use term_clear_line()
To make sure that the previously displayed progress line is completely
covered up when the new line is shorter, commit 545dc345eb (progress:
break too long progress bar lines, 2019-04-12) added a bunch of
calculations to figure out how many characters it needs to overwrite
with spaces.

Use the just introduced term_clear_line() helper function to, well,
clear the last line, making all these calculations unnecessary, and
thus simplifying the code considerably.

Three tests in 't5541-http-push-smart.sh' 'grep' for specific text
shown in the progress lines at the beginning of the line, but now
those lines begin either with the ANSI escape sequence or with the
terminal width worth of space characters clearing the line.  Relax the
'grep' patterns to match anywhere on the line.  Note that only two of
these three tests fail without relaxing their 'grep' pattern, but the
third looks for the absence of the pattern, so it still succeeds, but
without the adjustment would potentially hide future regressions.

Note also that with this change we no longer need the length of the
previously displayed progress line, so the strbuf added to 'struct
progress' in d53ba841d4 (progress: assemble percentage and counters in
a strbuf before printing, 2019-04-05) is not strictly necessary
anymore.  We still keep it, though, as it avoids allocating and
releasing a strbuf each time the progress is updated.

SZEDER Gábor d7d90885e0 rebase: fix garbled progress display with '-x'
When running a command with the 'exec' instruction during an
interactive rebase session, or for a range of commits using 'git
rebase -x', the output can be a bit garbled when the name of the
command is short enough:

  $ git rebase -x true HEAD~5
  Executing: true
  Executing: true
  Executing: true
  Executing: true
  Executing: true)
  Successfully rebased and updated refs/heads/master.

Note the ')' at the end of the last line.  It gets more garbled as the
range of commits increases:

  $ git rebase -x true HEAD~50
  Executing: true)
  [ repeated 3 more times ]
  Executing: true0)
  [ repeated 44 more times ]
  Executing: true00)
  Successfully rebased and updated refs/heads/master.

Those extra numbers and ')' are remnants of the previously displayed
"Rebasing (N/M)" progress lines that are usually completely
overwritten by the "Executing: <cmd>" lines, unless 'cmd' is short and
the "N/M" part is long.

Make sure that the previously displayed "Rebasing (N/M)" line is
cleared by using the term_clear_line() helper function added in the
previous patch.  Do so only when not being '--verbose', because in
that case these "Rebasing (N/M)" lines are not printed as progress
(i.e. as lines with '\r' at the end), but as "regular" output (with
'\n' at the end).

A couple of other rebase commands print similar messages, e.g.
"Stopped at <abbrev-oid>... <subject>" for the 'edit' or 'break'
commands, or the "Successfully rebased and updated <full-ref>." at the
very end.  These are so long that they practically always overwrite
that "Rebasing (N/M)" progress line, but let's be prudent, and clear
the last line before printing these, too.

In 't3420-rebase-autostash.sh' two helper functions prepare the
expected output of four tests that check the full output of 'git
rebase' and thus are affected by this change, so adjust their
expectations to account for the new line clearing.

Note that this patch doesn't completely eliminate the possibility of
similar garbled outputs, e.g. some error messages from rebase or the
"Auto-merging <file>" message from within the depths of the merge
machinery might not be long enough to completely cover the last
"Rebasing (N/M)" line.  This patch doesn't do anything about them,
because dealing with them individually would result in way too much
churn, while having a catch-all term_clear_line() call in the common
code path of pick_commits() would hide the "Rebasing (N/M)" line way
too soon, and it would either flicker or be invisible.

Jonathan Tan 8d45ad8c29 t5551: test usage of chunked encoding explicitly
When run using GIT_TEST_PROTOCOL_VERSION=2, a test in t5551 fails
because 4 POSTs (probe, ls-refs, probe, fetch) are sent instead of 2
(probe, fetch).

One way to resolve this would be to relax the condition (from "= 2" to
greater than 1, say), but upon further inspection, the test probably
shouldn't be counting the number of POSTs. This test states that large
requests are split across POSTs, but this is not correct; the main
change is that chunked transfer encoding is used, but the request is
still contained within one POST. (The test coincidentally works because
Git indeed sends 2 POSTs in the case of a large request, but that is
because, as stated above, the first POST is a probing RPC - see
post_rpc() in remote-curl.c for more information.)

Therefore, instead of counting POSTs, check that chunked transfer
encoding is used. This also has the desirable side effect of passing
with GIT_TEST_PROTOCOL_VERSION=2.

SZEDER Gábor e532a90a9f t5551: use 'test_i18ngrep' to check translated output
The two tests 'invalid Content-Type rejected' and 'server-side error
detected' in 't5551-http-fetch-smart.sh' use "plain" 'grep' to check
that 'git clone' failed with the expected error message, but the
messages they are checking are translated, and, consequently, these
tests fail when the test script is run with GIT_TEST_GETTEXT_POISON
enabled.

Use 'test_i18ngrep' instead.

Morian Sonnet 30db18b148 submodule foreach: fix recursion of options
Calling

    git submodule foreach --recursive <subcommand> --<option>

leads to an error stating that the option --<option> is unknown to
submodule--helper. That is of course only, when <option> is not a valid
option for git submodule foreach.

The reason for this is, that above call is internally translated into a
call to submodule--helper:

    git submodule--helper foreach --recursive \
        -- <subcommand> --<option>

This call starts by executing the subcommand with its option inside the
first level submodule and continues by calling the next iteration of
the submodule foreach call

    git --super-prefix <submodulepath> submodule--helper \
      foreach --recursive <subcommand> --<option>

inside the first level submodule. Note that the double dash in front of
the subcommand is missing.

This problem starts to arise only recently, as the
PARSE_OPT_KEEP_UNKNOWN flag for the argument parsing of git submodule
foreach was removed in commit a282f5a906. Hence, the unknown option is
complained about now, as the argument parsing is not properly ended by
the double dash.

This commit fixes the problem by adding the double dash in front of the
subcommand during the recursion.

SZEDER Gábor cd1096b282 pager: add a helper function to clear the last line in the terminal
There are a couple of places where we want to clear the last line on
the terminal, e.g. when a progress bar line is overwritten by a
shorter line, then the end of that progress line would remain visible,
unless we cover it up.

In 'progress.c' we did this by always appending a fixed number of
space characters to the next line (even if it was not shorter than the
previous), but as it turned out that fixed number was not quite large
enough, see the fix in 9f1fd84e15 (progress: clear previous progress
update dynamically, 2019-04-12).  From then on we've been keeping
track of the length of the last displayed progress line and appending
the appropriate number of space characters to the next line, if
necessary, but, alas, this approach turned out to be error prone, see
the fix in 1aed1a5f25 (progress: avoid empty line when breaking the
progress line, 2019-05-19).  The next patch in this series is about to
fix a case where we don't clear the last line, and on occasion do end
up with such garbage at the end of the line.  It would be great if we
could do that without the need to deal with that without meticulously
computing the necessary number of space characters.

So add a helper function to clear the last line on the terminal using
an ANSI escape sequence, which has the advantage to clear the whole
line no matter how wide it is, even after the terminal width changed.
Such an escape sequence is not available on dumb terminals, though, so
in that case fall back to simply print a whole terminal width (as
reported by term_columns()) worth of space characters.

In 'editor.c' launch_specified_editor() already used this ANSI escape
sequence, so replace it with a call to this function.

SZEDER Gábor 077b979891 t3404: make the 'rebase.missingCommitsCheck=ignore' test more focused
The test 'rebase -i respects rebase.missingCommitsCheck = warn' is
mainly interested in the warning about the dropped commits, but it
checks the whole output of 'git rebase', including progress lines and
what not that are not at all relevant to 'rebase.missingCommitsCheck',
but make it necessary to update this test whenever e.g. the way we
show progress is updated (as it will happen in one of the later
patches of this series).

Modify the test to verify only the first four lines of 'git rebase's
output that contain all the important lines, notably the line
containing the "Warning:" itself and the oneline log of the dropped
commit.

In 't3404-rebase-interactive.sh' the expected output of several tests

Move these here documents into the corresponding 'test_expect_success'

René Scharfe 39c575c969 config: simplify parsing of unit factors
Just return the value of the factor or zero for unrecognized strings
instead of using an output reference and a separate return value to
indicate success.  This is shorter and simpler.

It basically reverts that function to before c8deb5a146 ("Improve error
messages when int/long cannot be parsed from config", 2007-12-25), while
keeping the better messages, so restore its old name, get_unit_factor(),
as well.

René Scharfe 664178e8e2 config: don't multiply in parse_unit_factor()
parse_unit_factor() multiplies the number that is passed to it with the
value of a recognized unit factor (K, M or G for 2^10, 2^20 and 2^30,
respectively).  All callers pass in 1 as a number, though, which allows
them to check the actual multiplication for overflow before they are
doing it themselves.

Ignore the passed in number and don't multiply, as this feature of
parse_unit_factor() is not used anymore.  Rename the output parameter to
reflect that it's not about the end result anymore, but just about the
unit factor.

René Scharfe 3fb72c7b4d config: use unsigned_mult_overflows to check for overflows
parse_unit_factor() checks if a K, M or G is present after a number and
multiplies it by 2^10, 2^20 or 2^30, respectively.  One of its callers
checks if the result is smaller than the number alone to detect
overflows.  The other one passes 1 as the number and does multiplication
and overflow check itself in a similar manner.

This works, but is inconsistent, and it would break if we added support
for a bigger unit factor.  E.g. 16777217T is 2^64 + 2^40, i.e. too big
for a 64-bit number.  Modulo 2^64 we get 2^40 == 1TB, which is bigger
than the raw number 16777217 == 2^24 + 1, so the overflow would go
undetected by that method.

Let both callers pass 1 and handle overflow check and multiplication
themselves.  Do the check before the multiplication, using
unsigned_mult_overflows, which is simpler and can deal with larger unit
factors.

Johannes Schindelin ed33bd8f30 t0001: fix on case-insensitive filesystems
On a case-insensitive filesystem, such as HFS+ or NTFS, it is possible
that the idea Bash has of the current directory differs in case from
what Git thinks it is. That's totally okay, though, and we should not
expect otherwise.

On Windows, for example, when you call

	cd C:\GIT-SDK-64

in a PowerShell and there exists a directory called `C:\git-sdk-64`, the
current directory will be reported in all upper-case. Even in a Bash
that you might call from that PowerShell. Git, however, will have
normalized this via `GetFinalPathByHandle()`, and the expectation in
t0001 that the recorded gitdir will match what `pwd` says will be
violated.

Let's address this by comparing these paths in a case-insensitive
manner when `core.ignoreCase` is `true`.
