Merge branch 'ds/maintenance-part-4'
Follow-up on the "maintenance part-3" which introduced scheduled maintenance tasks to support platforms whose native scheduling methods are not 'cron'. * ds/maintenance-part-4: maintenance: use Windows scheduled tasks maintenance: use launchctl on macOS maintenance: include 'cron' details in docs maintenance: extract platform-specific scheduling

@ -218,6 +218,122 @@ Further, the `git gc` command should not be combined with
|
|||
but does not take the lock in the same way as `git maintenance run`. If
|
||||
possible, use `git maintenance run --task=gc` instead of `git gc`.
|
||||
|
||||
The following sections describe the mechanisms put in place to run
|
||||
background maintenance by `git maintenance start` and how to customize
|
||||
them.
|
||||
|
||||
BACKGROUND MAINTENANCE ON POSIX SYSTEMS
|
||||
---------------------------------------
|
||||
|
||||
The standard mechanism for scheduling background tasks on POSIX systems
|
||||
is cron(8). This tool executes commands based on a given schedule. The
|
||||
current list of user-scheduled tasks can be found by running `crontab -l`.
|
||||
The schedule written by `git maintenance start` is similar to this:
|
||||
|
||||
-----------------------------------------------------------------------
|
||||
# BEGIN GIT MAINTENANCE SCHEDULE
|
||||
# The following schedule was created by Git
|
||||
# Any edits made in this region might be
|
||||
# replaced in the future by a Git command.
|
||||
|
||||
0 1-23 * * * "/<path>/git" --exec-path="/<path>" for-each-repo --config=maintenance.repo maintenance run --schedule=hourly
|
||||
0 0 * * 1-6 "/<path>/git" --exec-path="/<path>" for-each-repo --config=maintenance.repo maintenance run --schedule=daily
|
||||
0 0 * * 0 "/<path>/git" --exec-path="/<path>" for-each-repo --config=maintenance.repo maintenance run --schedule=weekly
|
||||
|
||||
# END GIT MAINTENANCE SCHEDULE
|
||||
-----------------------------------------------------------------------
|
||||
|
||||
The comments are used as a region to mark the schedule as written by Git.
|
||||
Any modifications within this region will be completely deleted by
|
||||
`git maintenance stop` or overwritten by `git maintenance start`.
|
||||
|
||||
The `crontab` entry specifies the full path of the `git` executable to
|
||||
ensure that the executed `git` command is the same one with which
|
||||
`git maintenance start` was issued independent of `PATH`. If the same user
|
||||
runs `git maintenance start` with multiple Git executables, then only the
|
||||
latest executable is used.
|
||||
|
||||
These commands use `git for-each-repo --config=maintenance.repo` to run
|
||||
`git maintenance run --schedule=<frequency>` on each repository listed in
|
||||
the multi-valued `maintenance.repo` config option. These are typically
|
||||
loaded from the user-specific global config. The `git maintenance` process
|
||||
then determines which maintenance tasks are configured to run on each
|
||||
repository with each `<frequency>` using the `maintenance.<task>.schedule`
|
||||
config options. These values are loaded from the global or repository
|
||||
config values.
|
||||
|
||||
If the config values are insufficient to achieve your desired background
|
||||
maintenance schedule, then you can create your own schedule. If you run
|
||||
`crontab -e`, then an editor will load with your user-specific `cron`
|
||||
schedule. In that editor, you can add your own schedule lines. You could
|
||||
start by adapting the default schedule listed earlier, or you could read
|
||||
the crontab(5) documentation for advanced scheduling techniques. Please
|
||||
do use the full path and `--exec-path` techniques from the default
|
||||
schedule to ensure you are executing the correct binaries in your
|
||||
schedule.
|
||||
|
||||
|
||||
BACKGROUND MAINTENANCE ON MACOS SYSTEMS
|
||||
---------------------------------------
|
||||
|
||||
While macOS technically supports `cron`, using `crontab -e` requires
|
||||
elevated privileges and the executed process does 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 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/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
|
||||
launchctl.plist(5) for more information.
|
||||
|
||||
|
||||
BACKGROUND MAINTENANCE ON WINDOWS SYSTEMS
|
||||
-----------------------------------------
|
||||
|
||||
Windows does not support `cron` and instead has its own system for
|
||||
scheduling background tasks. The `git maintenance start` command uses
|
||||
the `schtasks` command to submit tasks to this system. You can inspect
|
||||
all background tasks using the Task Scheduler application. The tasks
|
||||
added by Git have names of the form `Git Maintenance (<frequency>)`.
|
||||
The Task Scheduler GUI has ways to inspect these tasks, but you can also
|
||||
export the tasks to XML files and view the details there.
|
||||
|
||||
Note that since Git is a console application, these background tasks
|
||||
create a console window visible to the current user. This can be changed
|
||||
manually by selecting the "Run whether user is logged in or not" option
|
||||
in Task Scheduler. This change requires a password input, which is why
|
||||
`git maintenance start` does not select it by default.
|
||||
|
||||
If you want to customize the background tasks, please rename the tasks
|
||||
so future calls to `git maintenance (start|stop)` do not overwrite your
|
||||
custom tasks.
