Subject: [PATCH v2 3/4] maintenance: use launchctl on macOS
Date: Wed, 04 Nov 2020 20:06:07 +0000	[thread overview]
Message-ID: <0fafd75d100f343f7cff6471772ed9b12793f81e.1604520368.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.776.v2.git.1604520368.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

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].

[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.

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_CRONTAB.

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, so call it from the macOS-specific tests to ensure
the .plist files are well-formatted.

+BACKGROUND MAINTENANCE ON MACOS SYSTEMS
+---------------------------------------
+
+While macOS technically supports `cron`, using `crontab -e` requires
+elevated privileges and the executed process do not have a full user
+context. Without a full user context, Git and its credential helpers
+cannot access stored credentials, so some maintenance tasks are not
+functional.
+
+Instead, `git maintenance start` interacts with the `launchctl` tool,
+which is the recommended way to
+https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/ScheduledJobs.html[schedule timed jobs in macOS].
+
+Scheduling maintenance through `git maintenance (start|stop)` requires
+some `launchctl` features available only in macOS 10.11 or later.
+
+Your user-specific scheduled tasks are stored as XML-formatted `.plist`
+files in `~/Library/LaunchAgents/`. You can see the currently-registered
+tasks using the following command:
+
+-----------------------------------------------------------------------
+$ ls ~/Library/LaunchAgents/ | grep org.git-scm.git
+org.git-scm.git.daily.plist
+org.git-scm.git.hourly.plist
+org.git-scm.git.weekly.plist
+-----------------------------------------------------------------------
+
+One task is registered for each `--schedule=<frequency>` option. To
+inspect how the XML format describes each schedule, open one of these
+`.plist` files in an editor and inspect the `<array>` element following
+the `<key>StartCalendarInterval</key>` element.
+
+`git maintenance start` will overwrite these files and register the
+tasks again with `launchctl`, so any customizations should be done by
+creating your own `.plist` files with distinct names. Similarly, the
+`git maintenance stop` command will unregister the tasks with `launchctl`
+and delete the `.plist` files.
+
+To create more advanced customizations to your background tasks, see
+https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingLaunchdJobs.html#//apple_ref/doc/uid/TP40001762-104142[the `launchctl` documentation]
+for more information.
