In-Portal has scheduled tasks section, where all actions that are performed
automatically are specified.
There are 2 ways to invoke these actions: -
- when somebody visits a page (default) - no way to ensure that
...
- scheduled task will be executed on time
...
- via cron - complete control and scheduled task protection
Setting for changing to cron invocation mode is located somewhere in
"Configuration -> Website -> Advanced" page and I bet nobody goes specially
and checks it.
I see several problems with it now: -
- scheduled task invocation method selected by default isn't optimal
...
- if user enabled "Run Scheduled Tasks from Cron" setting and don't add
...
- proper line (we don't show exact line anywhere) to crontab, then nothing
...
- would work (but user could think it works)
I propose, that we:
...
Solution
- write last time, when cron.php script was executed and it's execution
...
- method: web/cli;
...
- on scheduled task page:
...
- ask user to enable scheduled task execution via cron (quick link,
...
- like with Change Logs section) if we know
...
- that cron is running;
...
- if cron isn't running, then show exact crontab line, that user
...
- must add to it;
...
- if cron is running, but it's interval is larger, then 1
...
- minute (compare last recorded date with current execution date), then
...
- show warning, that it must be changed (on some hosting it's not allowed to run cron once per minute);
...
- show last cron execution date (right now I need to look at
...
- all scheduled tasks and find out which one was executed last);
...
- show relative scheduled task last/next run dates, e.g "5 min ago"
...
- or "in 10 hours", since it's easier to understand then comparing
...
- all scheduled task dates with current date (which even isn't shown on that page).
- highlight "last run date" in red if scheduled task was late (was executed not in between 2 last execution intervals); this in most cases would indicate that
