Subject: [PATCH 11/15] job-runner: use config for loop interval
Date: Fri, 03 Apr 2020 20:48:10 +0000	[thread overview]
Message-ID: <2c3c9d28a903e23c37e44f9783299f3c001f574e.1585946894.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.597.git.1585946894.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The 'git job-runner' process uses a sleep(X) call to pause its
operation between iterations of the job loop. This defaults to 30
minutes, but is now available to be done with longer or shorter
intervals according to the job.loopInterval config option. For
example, a user may want the job loop to run once every five
minutes while another wants the job loop to run once every six
hours.

This config value is checked immediately before the sleep(X) call,
which allows users to see the effect without restarting the
job-runner process. However, the process will be paused until the
previous sleep(X) call returns and the job loop is executed.

RFC QUESITON: Is this use of sleep(X) the best way to do this?
Is there a better way to delay the process for a time interval, or
until a specified time? This just seemed like the simplest option.
The job-runner is doing low-priority work on an unpredictable
schedule by design, so sleep(X) seemd appropriate.
