Support portable objects in the fedify CLI - #1199
Merged
Merged
Conversation
The fedify CLI did not use Fedify's FEP-ef61 support at all: lookup failed on ap: IDs without making a request, compatible identifiers were refused as cross-origin objects, inbox -f could not follow portable actors, -a of inbox and relay could not match them, and webfinger rejected portable IDs as invalid handles. This commit includes the following changes: - fedify lookup passes a portable object verifier to every lookupObject() and traverseCollection() call. The verifier always uses the follow-up loader, so documents it discovers, such as the owner of an unsecured collection, obey -p/--allow-private-address. - A new --gateway option for lookup, inbox, and webfinger gives the gateways for portable IDs without @gateway location hints. A hintless portable ID without --gateway fails before any request. - The lookup diagnostics record why a portable object was rejected and report it, e.g., an invalid integrity proof, or the loader failure that made the owner of a collection unavailable. - fedify lookup --recurse now goes through the same diagnostics for the first object and for linked objects, so a timeout is reported as a timeout instead of suggesting -a/--authorized-fetch. - inbox -f follows actors through Context.lookupObject(), and matchesActor() compares canonical portable IDs, so ap:, ap+ef61:, and compatible identifiers match regardless of location hints. It no longer treats a handle that cannot be looked up as a non-match, so a reject list fails closed. - fedify webfinger looks up a portable actor first, then its WebFinger address derived from its first gateway, and checks that the response links back to the actor. Its -p option was also ignored before, as the option was forwarded under the wrong name. - Generated vocabulary classes inspect IRIs with formatIri(), so the default output of fedify lookup shows ap+ef61://did:key:... instead of the percent-encoded URL form, falling back to URL.href for URLs that cannot be formatted. - docs/cli.md documents portable objects and the --gateway option.

The ID in "Rejected the portable object ..." came straight from the document a gateway served, so a percent-encoded ID such as ap://did%3Akey%3A.../note was printed as is, unlike the other portable diagnostics and contrary to docs/cli.md. It now goes through the same formatIdentifier() helper, which falls back to the raw string when the ID cannot be parsed. fedify-dev#1199 (comment) Assisted-by: Claude Code:claude-opus-5-5

Closes #1156, part of #288.
The CLI never passed a portable object verifier to
lookupObject()ortraverseCollection(), so it could not look up FEP-ef61 objects at all. This PR passes it throughfedify lookup,inbox,relay, andwebfinger, and makes--recursereport failures the way the other lookups do.How it works
Every lookup goes through
lookupWithDiagnostics()in packages/cli/src/diagnostics.ts, which now also wraps the verifier. When a lookup returnsnull, the CLI can report an invalid proof, an unsecured collection served by a gateway its owner does not list, or the timeout that made a collection's owner unreachable.lookupObject()only logs these failures.--recursenow uses the same path for the first object and for linked objects, so a timeout is reported as a timeout instead of a hint to try-a.The verifier always fetches with the follow-up loader, never with the loader
lookupObject()hands it. That loader allows private addresses for URLs given on the command line, and I did not want a remote collection to extend that permission to an owner it names. So documents discovered during verification follow-plike any other discovered URL.A new
--gatewayoption, built on #1158, supplies gateways for portable IDs without@gatewayhints. For command-line targets it replaces hints, as in the library. For--recurseit is only a fallback for links without hints, since a reply chain usually crosses DIDs. An ID with neither fails before any request rather than in the loader.fedify webfingercannot query a portable ID directly, as the ID has no host. It looks up the actor, derivesacct:preferredUsername@gatewayfrom its first gateway as FEP-ef61 says, and checks that the response links back to the actor. The actor'sgatewaysare its own claim, so the address counts only if the gateway confirms it.matchesActor()compares canonical portable IDs, soap:,ap+ef61:, and compatible IDs on any gateway match the same actor. When a handle lookup fails, it rethrows unless another entry matches, so arelay -rreject list fails closed.Outside the CLI
The default output of
fedify lookupisutil.inspect(), so printingap+ef61://did:key:…instead ofap+ef61://did%3Akey%3A…meant changing the generated inspector in packages/vocab-tools/src/inspector.ts. The generated inspector falls back toURL.hrefwhenformatIri()rejects a URL. Snapshots are updated for all three runtimes.While testing, I found that
fedify webfinger -pnever worked: the option was forwarded asallowPrivateAddresses, notallowPrivateAddress. It is fixed here; it might be worth backporting.Tests
packages/cli/src/portable.test.ts runs
fedify lookupagainst local gateways that serve objects signed with a realdid:key. It covers every identifier form, traversal through trusted and untrusted gateways, tampered proofs, gateway fallback, the private-address boundary, and--recursetimeouts with and without-T.
