Add configurable row-level exception handler

[jarednorman]

This add a new "row_exception_handler" preference which can be set to anything callable and is invoked when exceptions happen during row processing after the critical step of marking the context as unsuccessful and recording the message.

This can be used to report exceptions and the associated context to an error reporting services, something like:

SolidusImporter::Config.row_exception_handler = -> (e, context) {
  Sentry.capture_exception(e)
}

This addresses #50.

This needs a little more time in the oven.

Specs are failing just because factory loading is currently broken.

Specs are failing just because factory loading is currently broken.

@jarednorman I know a fix will be released for 2.11 in the next days, is it ok if we wait until then? After that we can update/fix the factory config and merge with a green CI

[jarednorman]

Yep, no rush. I tried out my branch in a staging env yesterday and will be taking it to production today, so we'll be able to merge it with extra confidence then as well. 🙂

@elia I rebased this against the latest master and fixed the conflict in process_row.rb, otherwise it is the same change as before.

[elia]

@jarednorman can you try rebasing again, now that master is green?

@jarednorman I think this is good to go but there are some annoying rubocop offenses, not sure how to proceed but I'd love to merge this improvement. WDYT?

[jarednorman]

I can take a pass an correct those offenses.

[jarednorman]

Oh, I thought I did this. 😅

[jarednorman]

I'm ready to throw my computer out a window if this set of changes doesn't pass on CI. 🤞🏻

[jarednorman]

Uh oh, it's not going to.

[jarednorman]

😌

[jarednorman]

Alright, I addressed the new incompatibility with Solidus master's version preferences in the most crude way, but should be fine for now.

Hey, I would like to use this. Is there anything else that needs to happen before this can be merged?

[jarednorman]

@benjaminwil You could point it at our branch until this gets merged and a new release cut: https://github.com/supergoodsoft/solidus_importer/tree/jardo/configurable-exception-handler
