Hi there, this is the official changelog page of FastCron.

Notify when cronjob succeeds after failed

New

Hi,

I've added a new feature to enable email/Slack notifications when your cronjob succeeds after it failed before.

It's enabled by default for new cronjobs.

To enable it, edit (or batch edit) your cronjobs, at the section Notifications, check the box Notify me: when cronjob fails, and when cronjob succeeds after failed.

notify

After that, when your cronjob fails, you'll receive an email/Slack notification. When your cronjob is okay again, you'll receive another message.

Notifications for several cronjobs may be combined into a single email, i.e. you may receive one failure notification for several cronjobs, and then one success notification for several cronjobs.

Slack messages won't be combined. You'll receive a separate Slack message for each cronjob.

Webhook requests are only sent for failed executions.

By default, FastCron always sends email/Slack notifications when your cronjobs are disabled because of multiple consecutive failures, and another message when they're okay again.

Feb 2024 updates

Hi,

I'll post the small updates in February 2024 below:

Thuan Thuan · 8w · 1017

Select all cron jobs

By default, the select-all checkbox only selects cronjobs with no group.

You can now select all cronjobs in your account under the Batch button.

select-all

After that, you can edit, run, enable, disable, or delete all cronjobs in your account.

Thuan Thuan · 17w · 1922

Ignore HTTP errors

See List of HTTP status codes.

If your cronjob URL returns an HTTP status code other than 2xx, FastCron will mark the cronjob execution as failed.

When editing your cronjobs, you can check the box HTTP error: Ignore redirects (3xx) and server errors (5xx). This will make FastCron ignore HTTP status codes 3xx and 5xx, and continue to execute your cronjob as usual.

http-error

FastCron will no longer ignore 4xx errors and will mark your cronjob as failed.

2 Thuan Thuan · 18w · 1982

Export CSV / ICS

You can now export your cronjobs as a CSV file. You can open it with Google Sheets or Excel. It's great for comparing cronjobs settings.

export

I also added the ability to export as ICS (calendar file), which you can view or import to your calendar. It'll show the times each cronjob executes.
You can upload it to https://larrybolt.github.io/online-ics-feed-viewer/, select list or month display to view the scheduled execution times.

Thuan Thuan · 18w · 1998

Max instances / overlapping executions

FastCron runs cronjobs at the scheduled times by default, regardless of ongoing executions. If a cronjob takes more time to run than its interval, it leads to overlapping executions.

Before, you could prevent cronjob executions from overlapping by enabling the Single instance feature.

Now, you can allow up to 5 overlapping executions by adjusting the Max instances: instances

The table below shows running executions when you allow up to 3 overlaps:

Time Running executions Events
1 1
2 1,2
3 1,2,3
4 1,2,3 4 is skipped
5 1,3,5 2 complete
6 3, 5, 6 1 is removed
7 3, 5, 6 7 is skipped
8 6, 8 3 and 5 complete
9 9 6 and 8 complete
  • When there are 3 running executions, new executions are skipped.
  • When one execution is complete, another execution starts running.
  • When you remove a running execution (visit the Running tab, delete a running execution), another execution starts running.

Please note that removing a running execution just deletes it from our database. The execution will continue to run until it's complete or timed out.

API function cron_add and cron_edit update: single is deprecated, please use instances instead.

November 2023 Update

Improved

Hi, here are some changes in this November:

Changes

  • Recurring cronjob limit has been added to the Platinum and Diamond accounts. No action is required.
  • The free account is now free forever. No action is required.
  • You can now choose multiple servers to execute your cronjobs from. If you choose Any server, it'll be executed from any server.

  • Password field now can be toggled (show/hide password).
  • After adding a new cronjob/group, scroll to the newly created item.
  • Add links to upgrade your account to enable premium features (custom HTTP headers and user agent string, single instance, retry failures, output pattern matches).

Bypass cache by adding __random__ to your cronjob URL

Improved

The server cache stores the script output and sends it back to users. It'll make your website faster. But, it also stops FastCron from running your cronjobs.

To bypass the server cache, you can add the __random__ keyword to your cronjob URL like this https://example.com/cron.php?__random__
or
https://example.com/cron.php?name=value&__random__

FastCron can do it for you automatically.
Just visit the Account settings page, and check the box Automatically update cronjob URL with __random__ to bypass cache.

The next time your cronjob executes, FastCron will add the __random__ keyword if it detects a server cache.

Thuan Thuan · 23w · 2622

Default cronjob settings

New

Hi,

I've added a new tab to change the default cronjob settings.

account-settings

You can now change:

  • Default timezone, which is also account timezone.
  • Cron server, if you'd like to run cronjobs from a specific server IP
  • Auto delete stopped cronjobs
  • Auto delete failed cronjobs
  • Auto add __random__ to cron job URLs to bypass cache.

For new users only: FastCron will now automatically delete stopped cronjobs after 30 days, and failed cronjobs 365 days. You can change it on the account settings page.

Thuan Thuan · 25w · 2912

Platinum and Diamond recurring cronjob limit

Hi,

On November 19, 2023, I will add a recurring cronjob limit to the Platinum and Diamond accounts.

No action is required. Your existing cronjobs will continue to work fine.

Recurring cronjobs are cron jobs that run repeatedly. Disabled, failed, and one-time cron jobs don't count.

It'll be the same as your yearly price. If you have a Platinum plan at $50/year, you can add up to 50 recurring cronjobs. If you already have more than 50 cronjobs, I'll adjust the limit so it can accommodate your usage and some more.

If you need more recurring cronjobs, you can get a special deal on the Billing page.

Thuan Thuan · 26w · 3034

One-time cronjob time settings

Fixed

If you're setting cronjobs to run once at a specific time, please ensure that it's at least 15 seconds into the future.

In the background, FastCron generates queued executions every 5 seconds. It also loads your cronjobs 3-5 seconds before the scheduled time to send to the cron servers and execute at the exact time.

For example, if it's 09:01:33, please set it to run after 09:01:47.

FastCron will now automatically adjust the scheduled time by 15 - 20 seconds if you set it to run too close to the present.

Also, as FastCron loads cronjob every 5 seconds, the scheduled time will be changed to the nearest available second value. In the example above, your cronjob will be scheduled to run at 09:01:50 instead of 09:01:47.

I hope this helps.

Thuan Thuan · 26w · 2950

Time filter

New

By default, the crontab uses OR when the day of the week and day of the month are specified.

For, example, 7 0 12 * Fri will run your cronjob at 00:07 on Friday OR on day 12 of each month.

dow-or-dom

It would be impossible to require matching of both the day of the week and the day of the month using either crontab syntax or time expression.

For example, run cronjobs on Friday the 12th, or run on Tuesday and Wednesday from day 10 to day 20.

To solve this, FastCron now supports the Time filter.

filter To show the Time filter, click on the Filter button.

It supports simple expressions with 5 variables:

  • minute: integer, from 0 to 59
  • hour: integer, from 0 to 23
  • day: integer, from 1 to 31
  • month: integer, from 1 to 12
  • weekday: string, including Mon, Tue, Wed, Thu, Fri, Sat, and Sun

It supports a lot of operators. See the full list here.

Here are some examples for you:

  • Run on Friday the 12th, at 8:00: set the expression to 1 day 8:00 (or 0 8 * * *) and the filter to day == 12 and weekday == 'Fri'
  • Run only on Tuesday and Wednesday, from day 10 to 20: (weekday == 'Tue' or weekday == 'Wed') and day >= 10 and day <= 20 or weekday in ['Tue', 'Wed'] and day >= 10 and day <= 20

This feature is available for the Indie, Team, and Business plans.

If you need some custom time settings, comment below and I'll help.

I've found and fixed a bug that updated your account's member limit incorrectly.

Enable login throttling

New

A common brute-force attack against web applications consists of an attacker submitting a login form many times with the hope of eventually guessing the password of some user account.

One of the best countermeasures to these attacks is called "login throttling", which denies a user from attempting logins after a certain number of failed attempts.

From now on, FastCron allows only 5 login attempts per minute.

38w · 4010

Run another cronjob after execution

New

You can now run another cronjob after a cronjob's successful execution. You should also disable the target cronjob if you want it to completely depend on the source cronjob.

This will double the daily execution count in the source cronjob. The feature is available in the premium plans.

run-cronjob

38w · 4018

Downgrade to free

Your account will be automatically downgraded to free 1 month after its expiration.

You can also choose to downgrade your account when it expires or has less than 7 days remaining.
