Don't discard invalidations when transformer throws an error #7547

mischnic · 2022-01-10T21:31:18Z

No invalidation gets added to the graph if runTransform throws an error. So instead catch it and return the error along with invalidations that were added along the way

Closes #6124

Somehow returning the ThrowableDiagnostic object as opposed to throwing it strips the diagnostics property on the other thread. Might be a difference between structured cloning vs v8's serialization...

mischnic · 2022-01-12T22:19:25Z

Turns out that when throwing an error the worker farm automatically serializes

parcel/packages/core/workers/src/WorkerFarm.js

Line 309 in 4745cd3

content: anyToDiagnostic(e),

and deserializes

parcel/packages/core/workers/src/WorkerFarm.js

Lines 337 to 339 in 4745cd3

    
           if (result.contentType === 'error') { 
        
             throw new ThrowableDiagnostic({diagnostic: result.content}); 
        
           }

the ThrowableDiagnostic. So I'm doing that manually now for that added error property on the return value.

Great, thank you so much folks <3 Do we have an idea when this will be released?

Edit: Sorry, I just realized it shipped along v2.2.1 already. And… it solved the very last issue I had with Parcel v2 🎉

You're amazing, keep up the good work 👍 🙏

parcel-bundler/parcel#7547 🎉

objarni · 2022-01-18T19:38:14Z

Thanks for your efforts!

Did some testing with parcel 2.2.1 and a small Elm app (https://github.com/objarni/KataDB/ ) with following setup:

npm install
npm start

npm start is a shorthand for "parcel".

Observations using Sublime Text's Ctrl+S to save and Firefox browser:

Modifying title in src/index.html hotreloads
Changing string "Filter by tag" in src/Main.elm hotreloads
Changing string "Most recently used" in src/KataDb.elm DOES NOT hotreload, however hitting Ctrl+R in Firefox does refresh the page/app, so rebuilding of the Elm app has probably happened "behind the scenes" but not percolated to the surface. Edit: indeed rebuilding does happen, I can see the terminal "Built in 66ms" flashing "Building" when saving KataDb.elm!

Hypothesis: hotreloading works for html files and the "first" Elm file (Main.elm), but not dependent .elm files like KataDb.

w0rm · 2022-01-19T07:59:56Z

@objarni I imagine hot reloading would keep the current model and swap out update and view. KataDb.elm contains a constant that is used to initiate the model, therefore changing it doesn't hot reload at runtime.

objarni · 2022-01-19T09:02:27Z

@w0rm that makes sense! Do you have any advice on what would trigger a re-init of the model except refreshing page?

w0rm · 2022-01-19T12:51:50Z

@objarni I think manually refreshing the page is probably acceptable in such cases. It is a non trivial task for the hot reload to tell apart this type of change.
