Commit 83bbf9b92e (mergetool--lib: improve support for vimdiff-style tool
variants, 2020-07-29) introduced a regression in the output of `git mergetool
--tool-help` and `git difftool --tool-help` [1].
In function 'show_tool_names' in git-mergetool--lib.sh, we loop over the
supported mergetools and their variants and accumulate them in the variable
'variants', separating them with a literal '\n'.
The code then uses 'echo $variants' to turn these '\n' into newlines, but this
behaviour is not portable, it just happens to work in some shells, like
dash(1)'s 'echo' builtin.
For shells in which 'echo' does not turn '\n' into newlines, the end
result is that the only tools that are shown are the existing variants
(except the last variant alphabetically), since the variants are
separated by actual newlines in '$variants' because of the several
'echo' calls in mergetools/{bc,vimdiff}::list_tool_variants.
Fix this bug by embedding an actual line feed into `variants` in
show_tool_names(). While at it, replace `sort | uniq` by `sort -u`.
To prevent future regressions, add a simple test that checks that a few
known tools are correctly shown (let's avoid counting the total number
of tools to lessen the maintenance burden when new tools are added or if
'--tool-help' learns additional logic, like hiding tools depending on
the current platform).

The last test of t4129 creates a directory and expects its setgid bit
(g+s) to be off. But this makes the test fail when the parent directory
has the bit set, as setgid's state is inherited by newly created
subdirectories.
One way to solve this problem is to allow the presence of this bit when
comparing the return of `test_modebits` with the expected value. But
then we may have the same problem in the future when other tests start
using `test_modebits` on directories (currently t4129 is the only one)
and forget about setgid. Instead, let's make the helper function more
robust with respect to the state of the setgid bit in the test directory
by removing this bit from the returning value. There should be no
problem with existing callers as no one currently expects this bit to be
on.
Note that the sticky bit (+t) and the setuid bit (u+s) are not
inherited, so we don't have to worry about those.

p7519 measures the performance of the fsmonitor code. To do this, it
uses the installed copy of Watchman. If Watchman isn't installed, a noop
integration script is installed in its place.
When in the latter mode, it is expected that the script should not write
a "last update token": in fact, it doesn't write anything at all since
the script is blank.
Commit 33226af42b (t/perf/fsmonitor: improve error message if typoing
hook name, 2020-10-26) made sure that running 'git update-index
--fsmonitor' did not write anything to stderr, but this is not the case
when using the empty Watchman script, since Git will complain that:
$ which watchman
watchman not found
$ cat .git/hooks/fsmonitor-empty
$ git -c core.fsmonitor=.git/hooks/fsmonitor-empty update-index --fsmonitor
warning: Empty last update token.
Prior to 33226af42b, the output wasn't checked at all, which allowed
this noop mode to work. But, 33226af42b breaks p7519 when running it
without a 'watchman(1)' on your system.
Handle this by only checking that the stderr is empty only when running
with a real watchman executable. Otherwise, assert that the error
message is the expected one when running in the noop mode.

Git's background maintenance uses cron by default, but this is not
available on Windows. Instead, integrate with Task Scheduler.
Tasks can be scheduled using the 'schtasks' command. There are several
command-line options that can allow for some advanced scheduling, but
unfortunately these seem to all require authenticating using a password.
Instead, use the "/xml" option to pass an XML file that contains the
configuration for the necessary schedule. These XML files are based on
some that I exported after constructing a schedule in the Task Scheduler
GUI. These options only run background maintenance when the user is
logged in, and more fields are populated with the current username and
SID at run-time by 'schtasks'.
Since the GIT_TEST_MAINT_SCHEDULER environment variable allows us to
specify 'schtasks' as the scheduler, we can test the Windows-specific
logic on other platforms. Thus, add a check that the XML file written
by Git is valid when xmllint exists on the system.
Since we use a temporary file for the XML files sent to 'schtasks', we
prefix the random characters with the frequency so it is easier to
examine the proper file during tests. Instead of an exact match on the
'args' file, we 'grep' for the arguments other than the filename.
There is a deficiency in the current design. Windows has two kinds of
applications: GUI applications that start by "winmain()" and console
applications that start by "main()". Console applications are attached
to a new Console window if they are not already associated with a GUI
application. This means that every hour the scheudled task launches a
command window for the scheduled tasks. Not only is this visually
obtrusive, but it also takes focus from whatever else the user is
doing!
A simple fix would be to insert a GUI application that acts as a shim
between the scheduled task and Git. This is currently possible in Git
for Windows by setting the <Command> tag equal to
C:\Program Files\Git\git-bash.exe
with options "--hide --no-needs-console --command=cmd\git.exe"
followed by the arguments currently used. Since git-bash.exe is not
included in Windows builds of core Git, I chose to leave out this
feature. My plan is to submit a small patch to Git for Windows that
converts the use of git.exe with this use of git-bash.exe in the
short term. In the long term, we can consider creating this GUI
shim application within core Git, perhaps in contrib/.

The existing mechanism for scheduling background maintenance is done
through cron. The 'crontab -e' command allows updating the schedule
while cron itself runs those commands. While this is technically
supported by macOS, it has some significant deficiencies:
1. Every run of 'crontab -e' must request elevated privileges through
the user interface. When running 'git maintenance start' from the
Terminal app, it presents a dialog box saying "Terminal.app would
like to administer your computer. Administration can include
modifying passwords, networking, and system settings." This is more
alarming than what we are hoping to achieve. If this alert had some
information about how "git" is trying to run "crontab" then we would
have some reason to believe that this dialog might be fine. However,
it also doesn't help that some scenarios just leave Git waiting for
a response without presenting anything to the user. I experienced
this when executing the command from a Bash terminal view inside
Visual Studio Code.
2. While cron initializes a user environment enough for "git config
--global --show-origin" to show the correct config file information,
it does not set up the environment enough for Git Credential Manager
Core to load credentials during a 'prefetch' task. My prefetches
against private repositories required re-authenticating through UI
pop-ups in a way that should not be required.
The solution is to switch from cron to the Apple-recommended [1]
'launchd' tool.
[1] https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/ScheduledJobs.html
The basics of this tool is that we need to create XML-formatted
"plist" files inside "~/Library/LaunchAgents/" and then use the
'launchctl' tool to make launchd aware of them. The plist files
include all of the scheduling information, along with the command-line
arguments split across an array of <string> tags.
For example, here is my plist file for the weekly scheduled tasks:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0"><dict>
<key>Label</key><string>org.git-scm.git.weekly</string>
<key>ProgramArguments</key>
<array>
<string>/usr/local/libexec/git-core/git</string>
<string>--exec-path=/usr/local/libexec/git-core</string>
<string>for-each-repo</string>
<string>--config=maintenance.repo</string>
<string>maintenance</string>
<string>run</string>
<string>--schedule=weekly</string>
</array>
<key>StartCalendarInterval</key>
<array>
<dict>
<key>Day</key><integer>0</integer>
<key>Hour</key><integer>0</integer>
<key>Minute</key><integer>0</integer>
</dict>
</array>
</dict>
</plist>
The schedules for the daily and hourly tasks are more complicated
since we need to use an array for the StartCalendarInterval with
an entry for each of the six days other than the 0th day (to avoid
colliding with the weekly task), and each of the 23 hours other
than the 0th hour (to avoid colliding with the daily task).
The "Label" value is currently filled with "org.git-scm.git.X"
where X is the frequency. We need a different plist file for each
frequency.
The launchctl command needs to be aligned with a user id in order
to initialize the command environment. This must be done using
the 'launchctl bootstrap' subcommand. This subcommand is new as
of macOS 10.11, which was released in September 2015. Before that
release the 'launchctl load' subcommand was recommended. The best
source of information on this transition I have seen is available
at [2]. The current design does not preclude a future version that
detects the available fatures of 'launchctl' to use the older
commands. However, it is best to rely on the newest version since
Apple might completely remove the deprecated version on short
notice.
[2] https://babodee.wordpress.com/2016/04/09/launchctl-2-0-syntax/
To remove a schedule, we must run 'launchctl bootout' with a valid
plist file. We also need to 'bootout' a task before the 'bootstrap'
subcommand will succeed, if such a task already exists.
The need for a user id requires us to run 'id -u' which works on
POSIX systems but not Windows. Further, the need for fully-qualitifed
path names including $HOME behaves differently in the Git internals and
the external test suite. The $HOME variable starts with "C:\..." instead
of the "/c/..." that is provided by Git in these subcommands. The test
therefore has a prerequisite that we are not on Windows. The cross-
platform logic still allows us to test the macOS logic on a Linux
machine.
We can verify the commands that were run by 'git maintenance start'
and 'git maintenance stop' by injecting a script that writes the
command-line arguments into GIT_TEST_MAINT_SCHEDULER.
An earlier version of this patch accidentally had an opening
"<dict>" tag when it should have had a closing "</dict>" tag. This
was caught during manual testing with actual 'launchctl' commands,
but we do not want to update developers' tasks when running tests.
It appears that macOS includes the "xmllint" tool which can verify
the XML format. This is useful for any system that might contain
the tool, so use it whenever it is available.
We strive to make these tests work on all platforms, but Windows caused
some headaches. In particular, the value of getuid() called by the C
code is not guaranteed to be the same as `$(id -u)` invoked by a test.
This is because `git.exe` is a native Windows program, whereas the
utility programs run by the test script mostly utilize the MSYS2 runtime,
which emulates a POSIX-like environment. Since the purpose of the test
is to check that the input to the hook is well-formed, the actual user
ID is immaterial, thus we can work around the problem by making the the
test UID-agnostic. Another subtle issue is the $HOME environment
variable being a Windows-style path instead of a Unix-style path. We can
be more flexible here instead of expecting exact path matches.

t6016 manually reconstructs git log --graph output by using the reported
commit hashes from `git rev-parse`. Each tag is converted into an
environment variable manually, and then `echo`-ed to an expected output
file, which is in turn compared to the actual output.
The expected output is difficult to read and write, because, e.g.,
each line of output must be prefaced with echo, quoted, and properly
escaped. Additionally, the test is sensitive to trailing whitespace,
which may potentially be removed from graph log output in the future.
In order to reduce duplication, ease troubleshooting of failed tests by
improving readability, and ease the addition of more tests to this file,
port the operations to `lib-log-graph.sh`, which is already used in
several other tests, e.g., t4215. Give all merges a simple commit

single simple assignment, with no need for looping or recursion.
Therefore, simplify the implementation.
While at it, take advantage of the fact that variable names to be
