fix: gateway conformance improvements #85

Title

fix: gateway conformance improvements

Description

A lot of changes here to fix requests from the gateway-conformance tests. This PR unblocks the ability to start improving
the gateway conformance of @helia/verified-fetch because most requests are now fully received and responded to by our basic-server.

This change depends on a bug fix in @helia/utils, ipfs/helia#542

Fixes ipfs/service-worker-gateway#266
Fixes #84

Summary of changes

gateway-conformance changes
- Implement IPFS_NS_MAP resolution
  - dnslinks are resolved with local dns resolver
  - ipns records are loaded into Helia datastore (this could likely be improved, but TestGatewayIPNSPath is passing at 100% now)
- removes reverse-proxy.js since it's no longer needed (less moving parts.. closer to verified-fetch)
- fixes shutdown logic of basic-server and test fixtures.
- Implements a HACK for gateway-conformance lack of support for subdomains with ports. see fixingGwcAnnoyance in basic-server.js
  - related to bug: gateway-conformance subdomains are inflexible and setup is not clear gateway-conformance#185 (comment)
- adds request url suffix to logger in basic-server.js to help debug issues with the gateway conformance tests.
- constructs explicit Helia instance that is passed to verified-fetch so we can override things as necessary
  - remove delegated routing (we don't want remote work)
  - customize datastore so we can load/resolve ipns records
- changes individual tests we run that are substrings of other individual test names to explicitly skip the longer name (so the tests are more isolated). e.g. TestTrustlessRaw should not run TestTrustlessRawRanges tests.
verified-fetch changes
- Added getRedirectResponse util that is called prior to calling codecHandlers in order to satisfy the gateway conformance tests
  - We will likely need to adjust this logic because this dropped successRate of TestDagPbConversion and others.
- Re-orders the REGEX order in matchURLString to resolve /ipns/ paths trigger false-positive DNSLink lookup service-worker-gateway#266 and adds a test for it
- Returns a 404 for raw requests that have a path, since we can't walk paths on raw IPFS content.
  - Fixes test is passed a filename from a deep traversal if it is available that broke when implementing this change to actually construct a folder with nested content.

Notes & open questions

Returns a 404 for raw requests that have a path, since we can't walk paths on raw IPFS content.

Are there any nuances with the fix I added here we need to handle? maybe something with query/search handler.. but i believe that's already being handled elsewhere (e.g. parseUrl/resource)

Change checklist

I have performed a self-review of my own code
I have made corresponding changes to the documentation if necessary (this includes comments as well)
I have added tests that prove my fix is effective or that my feature works

How come some of these tests have a lower sucessRate threshold?

Honestly not 100% sure but i think its because requests werent making it to the endpoint and we had false negatives.

Since gwc is still being fleshed out & unit tests &interop are passing i think this is acceptable for now.

This should be the last time we have to adjust successRate to satisfy wishy-washy issues.

It would be nice to be able to output gwc failing/successful tests so we could compare more easily than manually parsing the json

Why do you abort here?

To kill verified-fetch work that may still be ongoing (session findProvider loop is one I can think of that may still be going)

Got it, this seems a little counter intuitive that there may still be ongoing requests even after the promise is resolved.

Maybe it's something worth documenting with regards to sessions?

What do you think about adding a test for this function that illustrate when it redirects?

Suggested change

export async function getRedirectResponse ({ resource, options, logger, cid }: GetRedirectResponse): Promise<null | Response> {

// See https://specs.ipfs.tech/http-gateways/path-gateway/#location-response-header

export async function getRedirectResponse ({ resource, options, logger, cid }: GetRedirectResponse): Promise<null | Response> {

It really should have a test, but gwc tests it, so i figured it was fine for now. Since we already have gwc tests, redoing all that coverage in unit tests is not ideal.

Ill add a basic test

Added some comments and suggestions. No major objections from me as this in essence should increase confidence with the tests

unsure about this one, but tests seem to work for now. I would like to leave this until i'm sure gwc tests don't depend on it. If we are debugging a test failure and end up here, it may trigger idea for a fix.
