builtin/merge.c - cleanup of code in for-cycle that tests strategies

The cmd_merge() function has a loop that tries different
merge strategies in turn, and stops when a strategy gets a
clean merge, while keeping the "best" conflicted merge so
far.

Make the loop easier to follow by moving the code around,
ensuring that there is only one "break" in the loop where
an automerge succeeds. Also group the actions that are
performed after an automerge succeeds together to a single
location, outside and after the loop.

t3420: remove progress lines before comparing output

Some of the tests check the output of rebase is what we expect. These
were added after a regression that added unwanted stash output when
using --autostash. They are useful as they prevent unintended changes to
the output of the various rebase commands. However they also include all
the progress output which is less useful as it only tests what would be
written to a dumb terminal which is not the normal use case. The recent
changes to fix clearing the line when printing progress necessarily
meant making an ugly change to these tests. Address this my removing the
progress output before comparing it to the expected output. We do this
by removing everything before the final "\r" on each line as we don't
care about the progress indicator, but we do care about what is printed
immediately after it.

and (although slightly broken) in the git-wrapper.

Even unrelated projects such as GitExtensions and TortoiseGit need to

gettext: always use UTF-8 on native WindowsKarsten Blees Wed, 3 Jul 2019 20:46:04 +0000 (13:46 -0700)

gettext: always use UTF-8 on native Windows

On native Windows, Git exclusively uses UTF-8 for console output (both
with MinTTY and native Win32 Console). Gettext uses `setlocale()` to
determine the output encoding for translated text, however, MSVCRT's
`setlocale()` does not support UTF-8. As a result, translated text is
encoded in system encoding (as per `GetAPC()`), and non-ASCII chars are
mangled in console output.

Side note: There is actually a code page for UTF-8: 65001. In practice,
it does not work as expected at least on Windows 7, though, so we cannot
use it in Git. Besides, if we overrode the code page, any process
spawned from Git would inherit that code page (as opposed to the code
page configured for the current user), which would quite possibly break
e.g. diff or merge helpers. So we really cannot override the code page.

In `init_gettext_charset()`, Git calls gettext's
`bind_textdomain_codeset()` with the character set obtained via
`locale_charset()`; Let's override that latter function to force the
encoding to UTF-8 on native Windows.

In Git for Windows' SDK, there is a `libcharset.h` and therefore we
define `HAVE_LIBCHARSET_H` in the MINGW-specific section in
`config.mak.uname`, therefore we need to add the override before that
conditionally-compiled code block.

Rather than simply defining `locale_charset()` to return the string
`"UTF-8"`, though, we are careful not to break `LC_ALL=C`: the
`ab/no-kwset` patch series, for example, needs to have a way to prevent
Git from expecting UTF-8-encoded input.

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.

ci: don't update HomebrewSZEDER Gábor Wed, 3 Jul 2019 10:47:47 +0000 (12:47 +0200)

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.

cherry-pick/revert: add --skip option

git am or rebase have a --skip flag to skip the current commit if the
user wishes to do so. During a cherry-pick or revert a user could
likewise skip a commit, but needs to use 'git reset' (or in the case
of conflicts 'git reset --merge'), followed by 'git (cherry-pick |
revert) --continue' to skip the commit. This is more annoying and
sometimes confusing on the users' part. Add a `--skip` option to make
skipping commits easier for the user and to make the commands more
consistent.

sequencer: rename reset_for_rollback to reset_merge

We are on a path to teach cherry-pick/revert how to skip commits. To
achieve this, we could really make use of existing functions.
reset_for_rollback is one such function, but the name does not
intuitively suggest to use it to reset a merge, which it was born to
perform, see 539047c ("revert: introduce --abort to cancel a failed
cherry-pick", 2011-11-23). Change the name to reset_merge to make
it more intuitive.

So detect when .keep files exist and stop enabling bitmaps

check_everything_connected: assume alternate ref tips... Jeff King Mon, 1 Jul 2019 13:18:15 +0000 (09:18 -0400)

check_everything_connected: assume alternate ref tips are valid

When we receive a remote ref update to sha1 "X", we want to check that
we have all of the objects needed by "X". We can assume that our
repository is not currently corrupted, and therefore if we have a ref
pointing at "Y", we have all of its objects. So we can stop our
traversal from "X" as soon as we hit "Y".

If we make the same non-corruption assumption about any repositories we
use to store alternates, then we can also use their ref tips to shorten
the traversal.

This is especially useful when cloning with "--reference", as we
otherwise do not have any local refs to check against, and have to
traverse the whole history, even though the other side may have sent us
few or no objects. Here are results for the included perf test (which
shows off more or less the maximal savings, getting one new commit and
sharing the whole history):

Test HEAD^ HEAD

object-store.h: move for_each_alternate_ref() from transport.h

There's nothing inherently transport-related about enumerating the
alternate ref tips. The code has lived in transport.[ch] because the
only use so far had been advertising available tips during transport.
But it could be used for more, and a future patch will teach rev-list to
access these refs.

Let's move it alongside the other alt-odb code, declaring it in
object-store.h with the implementation in sha1-file.c.

This lets us drop the inclusion of transport.h from receive-pack, which
perhaps shows how it was misplaced (though receive-pack is about
transporting objects, transport.h is mostly about the client side).

t7814: do not generate same commits in different repos

t7814 has repo tree like this

initial-repo
submodule
sub

In each repo 'submodule' and 'sub', a commit is made to add the same
initial file 'a' with the same message 'add a'. If tests run fast
enough, the two commits are made in the same second, resulting
identical commits.

There is nothing wrong with that per-se. But it could make the test
flaky. Currently all submodule odbs are merged back in the main
one (because we can't, or couldn't, access separate submodule repos
otherwise). But eventually we need to access objects from the right
repo.

Because the same commit could sometimes be present in both 'submodule'
and 'sub', if there is a bug looking up objects in the wrong repo,
sometimes it will go unnoticed because it finds the needed object in the
wrong repo anyway.

Fix this by changing commit time after every commit. This makes all
commits unique. Of course there are still identical blobs in different
repos, but because we often lookup commit first, then tree and blob,
unique commits are already quite safe.

ref-filter.c: find disjoint pattern prefixesTaylor Blau Wed, 26 Jun 2019 22:41:48 +0000 (17:41 -0500)

ref-filter.c: find disjoint pattern prefixes

Since cfe004a5a9 (ref-filter: limit traversal to prefix, 2017-05-22),
the ref-filter code has sought to limit the traversals to a prefix of
the given patterns.

That code stopped short of handling more than one pattern, because it
means invoking 'for_each_ref_in' multiple times. If we're not careful
about which patterns overlap, we will output the same refs multiple
times.

For instance, consider the set of patterns 'refs/heads/a/*',
'refs/heads/a/b/c', and 'refs/tags/v1.0.0'. If we naïvely ran:

for_each_ref_in("refs/heads/a/*", ...);
for_each_ref_in("refs/heads/a/b/c", ...);
for_each_ref_in("refs/tags/v1.0.0", ...);

we would see 'refs/heads/a/b/c' (and everything underneath it) twice.

Instead, we want to partition the patterns into disjoint sets, where we
know that no ref will be matched by any two patterns in different sets.
In the above, these are:

- {'refs/heads/a/*', 'refs/heads/a/b/c'}, and
- {'refs/tags/v1.0.0'}

Given one of these disjoint sets, what is a suitable pattern to pass to
'for_each_ref_in'? One approach is to compute the longest common prefix
over all elements in that disjoint set, and let the caller cull out the
refs they didn't want. Computing the longest prefix means that in most
cases, we won't match too many things the caller would like to ignore.

The longest common prefixes of the above are:

- {'refs/heads/a/*', 'refs/heads/a/b/c'} -> refs/heads/a/*
- {'refs/tags/v1.0.0'} -> refs/tags/v1.0.0

We instead invoke:

for_each_ref_in("refs/heads/a/*", ...);
for_each_ref_in("refs/tags/v1.0.0", ...);

Which provides us with the refs we were looking for with a minimal
amount of extra cruft, but never a duplicate of the ref we asked for.

Implemented here is an algorithm which accomplishes the above, which
works as follows:

1. Lexicographically sort the given list of patterns.

2. Initialize 'prefix' to the empty string, where our goal is to
build each element in the above set of longest common prefixes.

3. Consider each pattern in the given set, and emit 'prefix' if it
reaches the end of a pattern, or touches a wildcard character. The
end of a string is treated as if it precedes a wildcard. (Note that
there is some room for future work to detect that, e.g., 'a?b' and
'abc' are disjoint).

4. Otherwise, recurse on step (3) with the slice of the list
corresponding to our current prefix (i.e., the subset of patterns
that have our prefix as a literal string prefix.)

This algorithm is 'O(kn + n log(n))', where 'k' is max(len(pattern)) for
each pattern in the list, and 'n' is len(patterns).

By discovering this set of interesting patterns, we reduce the runtime
of multi-pattern 'git for-each-ref' (and other ref traversals) from
O(N) to O(n log(N)), where 'N' is the total number of packed references.

Running 'git for-each-ref refs/tags/a refs/tags/b' on a repository with
10,000,000 refs in 'refs/tags/huge-N', my best-of-five times drop from:

real 0m5.805s
user 0m5.188s
sys 0m0.468s

to:

real 0m0.001s
user 0m0.000s
sys 0m0.000s

On linux.git, the times to dig out two of the latest -rc tags drops from
0.002s to 0.001s, so the change on repositories with fewer tags is much
less noticeable.

progress: use term_clear_line()SZEDER Gábor Mon, 24 Jun 2019 18:13:18 +0000 (20:13 +0200)

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.

rebase: fix garbled progress display with '-x'SZEDER Gábor Thu, 27 Jun 2019 13:42:48 +0000 (15:42 +0200)

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.

mingw: use Unicode functions explicitlyJohannes Schindelin Thu, 27 Jun 2019 09:37:19 +0000 (02:37 -0700)

mingw: use Unicode functions explicitly

Many Win32 API functions actually exist in two variants: one with
the `A` suffix that takes ANSI parameters (`char *` or `const char *`)
and one with the `W` suffix that takes Unicode parameters (`wchar_t *`
or `const wchar_t *`).

The ANSI variant assumes that the strings are encoded according to
whatever is the current locale. This is not what Git wants to use on
Windows: we assume that `char *` variables point to strings encoded in
UTF-8.

There is a pseudo UTF-8 locale on Windows, but it does not work
as one might expect. In addition, if we overrode the user's locale, that
would modify the behavior of programs spawned by Git (such as editors,
difftools, etc), therefore we cannot use that pseudo locale.

Further, it is actually highly encouraged to use the Unicode versions
instead of the ANSI versions, so let's do precisely that.

Note: when calling the Win32 API functions _without_ any suffix, it
depends whether the `UNICODE` constant is defined before the relevant
headers are #include'd. Without that constant, the ANSI variants are
used. Let's be explicit and avoid that ambiguity.

mingw: embed a manifest to trick UAC into Doing The... Cesar Eduardo Barros Thu, 27 Jun 2019 08:49:33 +0000 (01:49 -0700)

mingw: embed a manifest to trick UAC into Doing The Right Thing

On Windows >= Vista, not having an application manifest with a
requestedExecutionLevel can cause several kinds of confusing behavior.

The first and more obvious behavior is "Installer Detection" of the
"User Account Control" (also known as "UAC") feature, where Windows
sometimes decides (by looking at things like the file name and even
sequences of bytes within the executable) that an executable is an
installer and should run elevated (causing the well-known popup dialog
to appear). In Git's context, subcommands such as "git patch-id" or "git
update-index" fall prey to this behavior.

The second and more confusing behavior is "File Virtualization". It
means that when files are written without having write permission, it
does not fail (as expected), but they are instead redirected to
somewhere else. When the files are read, the original contents are
returned, though, not the ones that were just written somewhere else.
Even more confusing, not all write accesses are redirected; Trying to
write to write-protected .exe files, for example, will fail instead of
redirecting.

In addition to being unwanted behavior, File Virtualization causes
dramatic slowdowns in Git (see for instance
http://code.google.com/p/msysgit/issues/detail?id=320).

A third unwanted behavior of Windows >= Vista is that it lies about the
Windows version when calling `GetWindowsVersionEx()`.

There are two ways to prevent these unwanted behaviors: Either you embed
an application manifest (which really is an XML document conforming to a
specific schema) within all your executables, or you add an external
manifest (a file with the same name followed by `.manifest`) to all your
executables. Since Git's builtins are hardlinked (or copied), it is
simpler and more robust to embed a manifest.

Recent enough MSVC compilers already embed a working internal manifest,
and building with mingw-w64 (which is the case in Git for Windows' SDK)
does it, too, but for MinGW you have to do so by hand.

In any case, it is better to be explicit about this manifest, that way
changes in the compiler toolchain won't surprise us (as mingw-w64 once
did when it broke `GetWindowsVersionEx()` by mistake).

between the performance impact and the provided safety.

status: do not report errors in sequencer/todo

commit 4a72486de9 ("fix cherry-pick/revert status after commit",
2019-04-16) used parse_insn_line() to parse the first line of the todo
list to check if it was a pick or revert. However if the todo list is
left over from an old cherry-pick or revert and references a commit that
no longer exists then parse_insn_line() prints an error message which is
confusing for users [1]. Instead parse just the command name so that the
user is alerted to the presence of stale sequencer state by status
reporting that a cherry-pick or revert is in progress.

Note that we should not be leaving stale sequencer state lying around
(or at least not as often) after commit b07d9bfd17 ("commit/reset: try
to clean up sequencer state", 2019-04-16). However the user may still
have stale state that predates that commit.

Also avoid printing an error message if for some reason the user has a
file called `sequencer` in $GIT_DIR.

sequencer: factor out todo command name parsingPhillip Wood Thu, 27 Jun 2019 14:12:45 +0000 (07:12 -0700)

sequencer: factor out todo command name parsing

Factor out the code that parses the name of the command at the start of
each line in the todo file into its own function so that it can be used
in the next commit.

As I don't want to burden other callers with having to pass in a pointer
to the end of the line the test for an abbreviated command is
changed. This change should not affect the behavior. Instead of testing
`eol == bol + 1` the new code checks for the end of the line by testing
for '\n', '\r' or '\0' following the abbreviated name. To avoid reading
past the end of an empty string it also checks that there is actually a
single character abbreviation before testing if it matches. This
prevents it from matching '\0' as the abbreviated name and then trying
to read another character.

t5551: test usage of chunked encoding explicitlyJonathan Tan Wed, 5 Jun 2019 19:26:24 +0000 (12:26 -0700)

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.

submodule foreach: fix recursion of optionsMorian Sonnet Mon, 24 Jun 2019 20:26:55 +0000 (22:26 +0200)

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.

msvc: avoid debug assertion windows in Debug Mode

For regular debugging, it is pretty helpful when a debug assertion in a
running application triggers a window that offers to start the debugger.

However, when running the test suite, it is not so helpful, in
particular when the debug assertions are then suppressed anyway because
we disable the invalid parameter checking (via invalidcontinue.obj, see
the comment in config.mak.uname about that object for more information).

So let's simply disable that window in Debug Mode (it is already
disabled in Release Mode).

msvc: support building Git using MS Visual C++Jeff Hostetler Tue, 25 Jun 2019 14:49:39 +0000 (07:49 -0700)

msvc: support building Git using MS Visual C++

With this patch, Git can be built using the Microsoft toolchain, via:

make MSVC=1 [DEBUG=1]

Third party libraries are built from source using the open source
"vcpkg" tool set. See https://github.com/Microsoft/vcpkg

On a first build, the vcpkg tools and the third party libraries are
automatically downloaded and built. DLLs for the third party libraries
are copied to the top-level (and t/helper) directory to facilitate
debugging. See compat/vcbuild/README.

A series of .bat files are invoked by the Makefile to find the location
of the installed version of Visual Studio and the associated compiler
tools (essentially replicating the environment setup performed by a
"Developer Command Prompt"). This should find the most recent VS2015 or
VS2017 installation. Output from these scripts are used by the Makefile
to define compiler and linker pathnames and -I and -L arguments.

The build produces .pdb files for both debug and release builds.

Note: This commit was squashed from an organic series of commits
developed between 2016 and 2018 in Git for Windows' `master` branch.
This combined commit eliminates the obsolete commits related to fetching
NuGet packages for third party libraries. It is difficult to use NuGet
packages for C/C++ sources because they may be built by earlier versions
of the MSVC compiler and have CRT version and linking issues.

Additionally, the C/C++ NuGet packages that we were using tended to not
be updated concurrently with the sources. And in the case of cURL and
OpenSSL, this could expose us to security issues.

pager: add a helper function to clear the last line... SZEDER Gábor Mon, 24 Jun 2019 18:13:16 +0000 (20:13 +0200)

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.

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.

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.

t0001: fix on case-insensitive filesystemsJohannes Schindelin Mon, 24 Jun 2019 17:40:05 +0000 (19:40 +0200)

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`.
