Only dedupe pagination queries if the variables match

[AlecAivazis]

This PR adds a new argument to the @dedupe directive: match which takes 3 values: Variables, Operation, and None. This gives the user more fine-grained control over how the deduping happens. Most importantly, for paginated queries, @dedupe comes with match set to Variables.

Can we also either have the option to opt in/out of dedupe behaviour? Or at least disable it for SSR? Currently all my tests are failing when running in parallel mode, because when multiple requests hit my endpoint that uses a @loading directive it throws a 500 with Aborted.

@half2me it should only be automatically deduping pagination queries. are you seeing something different?

Yes I am. Since I upgraded to this, a lot of tests started failing with the server returning status 500 Aborted error, for any page where I'm using pagination.

This definitely has something to do with multiple requests hitting the same page, since if I disable parallel workers for my tests, and run them just one at a time, they all work fine. Its only when simultaneous requests hit the same page that they break.,

@SeppahBaws i think i fixed what was wrong

@half2me i added a new config value supressPaginationDeduplication that you can set to prevent the deduplication

[half2me]

Amazing, I will rerun the tests and let you know. @AlecAivazis is there an easy way I can pin the houdini package in my package.json to point to this branch?

[SeppahBaws]

Ah awesome, I'll give this a shot once it's calmed down a bit more at work...

@half2me you can clone and build the repo locally, and then link it locally to your repo with npm/pnpm link: https://docs.npmjs.com/cli/v6/commands/npm-link https://pnpm.io/cli/link

(on npm you can also specify the package version as "file:../path/to/houdini/packages/houdini" - I did find that this messes up in pnpm though)
