An Unmanaged Package for installation into a sandbox or scratch org

Upload the code with SFDX. To be expanded upon later!

Configuration

1. Go to Custom Code > Custom Metadata
2. Click "Manage Records" on "Sentry Config"
3. Click "Edit" on "Default"
4. Put in your Sentry DSN in the "DSN" field
5. Save!

Additional configuration

There is also a Custom Setting which you can use.

1. Go to Custom Code > Custom Settings
2. Click "Manage Records" on "Sentry Active Config"
3. Click "New"
4. Environment Name is the name of the environment that will show up in Sentry.
5. Debug turns on developer debugging for the Salesforce for Sentry internals.
6. Is Issue Creation Disabled turns off sending errors to Sentry.
7. Sentry Config DeveloperName takes the DeveloperName of a Sentry Config entry, and uses that configuration. This makes it easy to have sentry disabled by default in cloned sandboxes. Just make a Sentry Config for Production, and set the Sentry Config DeveloperName to that in your Production environment.

Usage

try {
    doSomethingExceptional();
} catch (Exception e) {
    Sentry.record(e);
    throw e;
}

WAIT WHAT?! THAT WON'T WORK!

Behind the scenes, the exception is serialized, and published immediately to the EventBus, via the Sentry_Error__c event.

After that, an Apex Trigger is listening for new Sentry_Error__e after inserts, and hands them off to a @Future which makes the API calls to Sentry.

This means you can record exceptions AND throw them, to prevent bad things from happening.

Stack Traces

By default, Custom Exceptions in Apex do not get the privilege of having stack traces. See the known issue - no fix report for more details about that.

Don't give up hope, though! All is not lost!

If you use the Sentry_Exception class included in this package, you will have stack traces exposed. It requires two steps to work correctly:

1. Extend your custom exception from Sentry_Exception instead of Exception.
2. Create your exception instances using the Sentry_ExceptionFactory.

Here's an example from Sentry_TestingThrower.cls:

public with sharing class Sentry_TestingThrower {
    class MyException extends Sentry_Exception {}

    public void throwException() {
        MyException ex = (MyException) Sentry_ExceptionFactory.build(MyException.class);
        ex.setMessage('Something broke.');
        throw ex;
    }
}

Logging

There is an included Sentry_Log class with methods for logging Error, Warn, Info, Debug, and Trace messages.

At some point this will get wired up to Sentry's breadcrumbs, to pass additional data through to your Sentry report.

Testing

Do you have everything configured and ready to go? Open up the Sentry Testing tab and click on that Trigger an exception! button.

You will see the sort of error you would expect with an uncaught exception being thrown.

Now check Sentry, and you should see an error present!

Contributing code

Help is definitely welcome! This does the basics, but it could be so much better!

Right now, it seriously needs some tests. Seriously.

The biggest tips I can give you for testing additional development work are:

1. Turn on Debug in the Active Sentry Config Custom Setting. It will make everything produce a lot more logs.
2. If you're working on something in the Sentry_Error_Handler, be sure to go to the Developer Console > Debug > Change Log Levels, and add the Automated Process user in the User Tracing for All Users section. The query to find the User Id you need is SELECT Id FROM User WHERE Name = 'Automated Process'.
