Fixes #18

Summary

Adds a public factory package. It imports the providers and returns a ready Client, so a caller can pass any repo URL and get the right forge back. Domains the client hasn't seen are detected and registered on first use.

client := factory.NewClient(forges.WithToken("git.example.com", token))

f, owner, repo, err := client.ForgeForURL(ctx, "https://git.example.com/octocat/hello-world")

Changes

factory package

• NewClient(opts...) registers github.com, gitlab.com, codeberg.org, bitbucket.org and tangled.org, and enables detection for every other domain. WithToken and WithHTTPClient reach the default forges. A domain registered with WithForge keeps that registration.
• DefaultForges(token, hc) and Builders() expose the same wiring. internal/resolve now uses them instead of its own copy, and its behaviour doesn't change: it still registers the same forges with the same tokens and HTTP client.

Root package

The root package can't import providers, so first-use detection is opt-in:

• WithDetection(builders) turns it on. Clients without it behave as before: an unknown domain is an error and nothing is probed.
• Client.ForgeForURL(ctx, repoURL) returns the forge, owner and repo.
• FetchRepository, FetchTags, ResolveCommit and ListRepositories use the same lookup, so they detect on first use too. ForgeFor(domain) stays a plain registry lookup, because it has no context to probe with.

Decisions to check

• Scheme: detection always uses https, whatever the scheme of the URL. A plain-HTTP instance has to be registered explicitly with RegisterDomain(ctx, "http://host", ...).
• Tokens: the probes themselves don't send the token. It goes to the forge built after detection, which is always https.
• Untrusted URLs: detection makes requests to whatever host the URL names. The WithDetection docs warn callers who handle untrusted URLs.
• Failures: failed detection isn't cached, so a transient failure can recover on the next call, and each retry probes again.
• Concurrency: lookups can now write to the registry, so a mutex guards the forge and token maps. If two goroutines detect the same new domain at once, both probe and build the same https forge, so the last registration winning is harmless.
• Tokens() behaviour change: it now returns a copy, because returning the live map would race with registration. Nothing in this repo calls it, but outside code that mutated the returned map would no longer affect the client.

Testing

• factory/factory_test.go covers default forge registration, options reaching the default forges, WithForge precedence, detection against an httptest TLS server (a single probe, the token reaching the API), an http:// URL followed by an https:// one on a host with a token (every request is https and the registration is https), detection failure, and concurrent first use under -race.
• forges_test.go covers no probing without the option, base URL selection for each URL form, invalid URLs, first-use detection through all four Client methods, and the Tokens() copy.
• Switching detection back to http or removing the detection fallback makes these tests fail.
• A throwaway read-only smoke test (not committed) ran FetchRepository through factory.NewClient against github.com, gitea.com, gitlab.gnome.org (detected as GitLab) and an scp-like codeberg.org URL, and all four returned the right repository.
• gofmt and go vet on the changed packages, go test -race . ./factory ./internal/resolve ./internal/cli, and GOOS=js and GOOS=wasip1 builds of ./factory pass. I didn't run the full matrix or golangci-lint locally.

Summary by CodeRabbit

• New Features
  • Added automatic detection of supported forges for HTTPS repository URLs on previously unregistered domains. Plain-HTTP instances require explicit registration.
  • Added a ready-to-use client with defaults for GitHub, GitLab, Codeberg, Bitbucket Cloud, and Tangled, while preserving custom forge registrations.
  • Repository operations, including commit resolution, can select a forge from a repository URL.
  • Domain matching in forge and configuration lookups is now case-insensitive.
• Documentation
  • Added examples for creating a client, selecting a forge from a repository URL, and registering an HTTP domain.

Merge Risk: Moderate · up to 1cd40

A redirected request could expose a configured token over HTTP, and concurrent detection could replace an explicitly configured forge or token. Address these risks before merging.

Security architecture risk: Moderate · up to 1cd40

Automatic discovery expands network access and credential use. Redirect handling, registration precedence, and conflicting domain configuration can weaken expected controls. Exposure is bounded by each application's adoption, configured credentials, and network policy; existing clients do not enable discovery automatically.

Retained concerns

• Medium · security · inferred: Automatic discovery starts with HTTPS but does not preserve an HTTPS-only credential boundary across redirects. For a newly detected Gitea or Forgejo host with a configured token, repository requests use an ordinary HTTP client. A same-host redirect to HTTP retains Authorization under the pinned Go redirect implementation, exposing the credential to an observer on the plaintext path. This requires such a redirect and is prevented by a restrictive caller-supplied policy. The transport behavior existed for explicit registrations; this PR makes it reachable through automatic first-use operations.
• Medium · security · inferred: Automatic registration does not preserve canonical identity and explicit authority through its commit. ListRepositories accepts a raw domain: a value such as git.example.com/ misses the registry, but RegisterDomain normalizes it to git.example.com and can replace that host's existing forge and token; the final lookup still fails on the original slash-suffixed key. Separately, an in-flight detection can overwrite a newer explicit registration with its earlier token snapshot. Both paths can replace an explicitly selected identity or provider policy. Construction-time WithForge preservation and mutex-protected writes do not prevent these transitions.
• Medium · security · inferred: Case normalization silently merges previously distinct configuration sections without deterministic conflict handling. For example, a lowercase section containing a token and scheme=https can now combine with a case-variant section containing scheme=http; map iteration determines the resulting scheme while retaining the token. The resolver can consequently send that credential over HTTP where the base selected the lowercase HTTPS section. This is limited to conflicting local user configuration, not a demonstrated remote configuration-write capability. SetDomain's preference for existing lowercase keys does not govern loadFile.

Security review details

Security Blast Radius

• inferred — A detection-enabled client can initiate requests to caller-selected hosts reachable through its HTTP transport, including internal destinations unless the embedding application restricts them. Registration effects are scoped to that client and canonical host. Credential exposure is bounded by the selected host's token and its downstream permissions; no deployed tenant, service, or environment scope was established.

Security Findings and Attack Paths

• inferred — For a configured Gitea or Forgejo credential, an automatically detected provider can send Authorization on a repository request and follow a same-host HTTPS-to-HTTP redirect without stripping it. A plaintext-path observer could obtain the credential. The initial TLS endpoint must produce the redirect, and a caller-supplied redirect restriction can block the path. This is an inherited transport weakness newly reached by automatic lookup, not evidence of an observed compromise.
• inferred — A caller able to supply a noncanonical raw domain to ListRepositories can trigger registration against a different key from the lookup key. Successful detection can then replace an existing host registration even though the outer operation returns an error. Concurrent first-use detection provides another route for older state to replace newer explicit credentials. Repository-URL parsing avoids the slash alias by extracting the host, but it does not prevent the concurrent commit problem.

Trust Boundaries and Controls

• observed — Discovery is an explicit root-client capability, and its documentation places untrusted-URL validation on callers. Existing registrations bypass discovery on an exact canonical lookup, factory construction preserves caller registrations, and injected HTTP clients provide a place for transport restrictions. These controls do not themselves supply a destination allowlist or an HTTPS-only redirect policy.

Resilience and Maintainability Implications

• inferred — Domain canonicalization needs a security-policy conflict rule, not merely a common spelling. Configuration loading can combine credentials and transport settings from different case variants, whereas SetDomain uses a different merge precedence. Scheme and token settings remain restricted to user configuration, limiting this concern to local configuration migration and control drift rather than an established project-file privilege escalation.

Hardening Proposals

• proposed — Define a discovery transport policy that rejects HTTPS downgrade and unauthorized origin changes for both probes and authenticated provider requests. Applications accepting untrusted repository URLs should additionally constrain destinations and effective redirect targets through their HTTP transport or egress policy.
• proposed — Validate and canonicalize domain identity before lookup, then commit automatic detection only if the same registration generation is still unclaimed. Preserve explicit registration authority without holding locks across network calls or builders. Apply one deterministic conflict policy to configuration loading and persistence, preferably rejecting conflicting credential or transport settings.

Full details: Out of Scope Changes check

Explanation

The factory wiring, root-client detection, and internal/resolve reuse implement [18]. Registry locking and token-copy behavior support concurrent first-use registration. Domain case normalization in the client, resolver, and config keeps host lookups consistent. The documentation and tests support these changes. No unrelated change is established.

Full details: Linked Issues check

Explanation

[18] factory.NewClient registers the five requested default domains and enables first-use detection. ForgeForURL and the repository methods use that detection path. However, forgeOrDetect always probes https:// plus the domain and discards the input URL scheme. An unseen HTTP-only domain therefore cannot be detected from its repository URL, although [18] asks callers to pass a repo URL and get the right forge with first-use detection.

Resolution

Use the explicit http:// scheme when detecting an HTTP repository URL, while retaining HTTPS detection for HTTPS and schemeless URLs. Add an automated test with an HTTP-only server that verifies first-use detection and registration.

[andrew]

Thanks for this. One thing needs changing before it can go in.

In ForgeForURL, the scheme of the first URL seen for an unregistered host decides how that host is registered, and the token from WithToken goes into that forge. So a single http://git.example.com/a/b registers the host over plain HTTP, and every later call sends the token in cleartext, including calls made from https:// URLs. The main input here is repository URLs from package metadata, which the caller doesn't control, so one stray http:// URL is enough. Because forgeOrDetect goes through RegisterDomain, which always overwrites, a late HTTP detection can also replace an HTTPS registration that another goroutine just made.

Please always detect over https and drop the scheme check in ForgeForURL. Plain-HTTP instances can still be registered explicitly with RegisterDomain(ctx, "http://host", ...). That also makes the concurrent overwrite harmless, since both sides build the same forge. If you'd rather keep HTTP detection, it needs to skip the token for http and only install when no entry exists, so an HTTP registration can't replace an HTTPS one.

Either way, add a test that uses an http:// URL on a host with a configured token before an https:// one, and checks that no token is sent over HTTP and the registration is https.

[NopeCharon]

Went with https only in 3402ce5. Detection now always probes over https, the scheme check in ForgeForURL is gone, and TestForgeForURLDetectsHTTPURLOverHTTPS uses an http:// URL before an https:// one on a host with a token and checks every request and the registration are https. I also rebased onto main, which needed Radicle added to factory.Builders().

Thanks, the https-only detection and the new test look right.

One more thing before this can go in. RegisterDomain only checks for a nil builder in the Gerrit, Tangled and Radicle cases; GitHub, GitLab and Gitea call the builder directly. That was already there, but WithDetection now runs it automatically for any host named in a repository URL. A caller who passes WithDetection(forges.ForgeBuilders{Gitea: gitea.New}) and then sees a URL for a host that answers with an X-GitHub-Request-Id header will hit a nil function call and panic. factory.Builders() fills every field, but WithDetection is public and the URLs come from package metadata the caller doesn't control.

Please add the same nil check to the GitHub, GitLab and Gitea cases so they return the "no builder registered" error, and add a test that uses a partial builder set against a host detected as one of those types and expects an error instead of a panic.

[NopeCharon]

Done in 037535e. RegisterDomain now picks the builder first and returns the "no builder registered" error for any forge type with a nil builder, and TestDetectionMissingBuilderReturnsError runs ForgeForURL with partial builders against hosts detected as GitHub, GitLab, Gitea and Forgejo and expects that error with nothing registered. I also rebased onto main.

Thanks, the nil-builder check and its test look right.

One more thing before this can go in. ParseRepoURL returns the host exactly as written, and the forge and token maps are keyed by that string. So with factory.NewClient, a URL like https://GitHub.com/octocat/hello-world misses the github.com entry and falls into forgeOrDetect. That probes https://GitHub.com, sees X-GitHub-Request-Id, and registers github.NewWithBase("https://GitHub.com", "") under the key GitHub.com. Every later call for that spelling then goes to https://GitHub.com/api/v3 as an Enterprise client, without the token configured for github.com. The same happens for GitLab.com, Codeberg.org, any self-hosted host that has a WithToken entry, and the domain argument of ListRepositories. The missing lowercasing was already there, but before WithDetection it gave a "no forge registered" error instead of a second, wrong registration. Mixed-case hosts are common in package metadata.

Please lowercase the host in ParseRepoURL (both the url.Parse path and the scp-like path) and in normalizeBaseURL, so lookup, token and registration all use the same key. Add a test that https://GitHub.com/owner/repo through factory.NewClient returns the default github.com forge and makes no probe request.

[NopeCharon]

Done in 85e420c. ParseRepoURL (both paths) and normalizeBaseURL now lowercase the host, and WithToken, WithForge, ForgeFor and the detection lookup use lowercased keys too, so ListRepositories with a mixed-case domain and --host style callers stay consistent. TestForgeForURLMatchesDefaultForgeCaseInsensitively checks that https://GitHub.com/owner/repo through factory.NewClient returns the default github.com forge without a probe.

[andrew]

Thanks, the host lowercasing and its tests look right for the library.

It has a knock-on effect in the CLI that needs fixing before this can go in. internal/config stores section names exactly as written, and configForgeType, configScheme, TokenForDomain, GitProtocolFor and DomainForSSHHost all match on the exact string. With a [Git.Example.com] section and a remote of git@Git.Example.com:owner/repo, ParseRepoURL used to return Git.Example.com and the section matched. It now returns git.example.com, so the token, type, scheme and git_protocol from that section are no longer found, and an ssh_host = Git.Example.com value stops matching the same way.

Please lowercase the section name when the config is loaded and in SetDomain, and compare ssh_host with strings.EqualFold in DomainForSSHHost. Add a test that resolves a mixed-case remote against a mixed-case config section and gets its token and type.

One smaller thing in RegisterDomain: the builder is called while c.mu is held, so a builder that calls c.Tokens() or c.ForgeFor() deadlocks. Call build(baseURL, token, c.httpClient) before taking the lock and do only the two map writes under it.

[NopeCharon]

Done in 1cd40c4. Config section names are lowercased on load and in SetDomain (which also folds an existing mixed-case section into the lowercase one), DomainForSSHHost uses strings.EqualFold, and the config lookups lowercase the domain. RegisterDomain now builds the forge before taking c.mu. Added tests for the mixed-case remote against a mixed-case section and for a builder that calls Tokens and ForgeFor.

Prevent detection from replacing an existing registration.

If explicit RegisterDomain completes while first-use detection is in progress, detection can overwrite its forge and token with the earlier token and an HTTPS forge. Later requests can then fail authentication or use the wrong endpoint.

Make detection insert the forge and token only if the domain is still unregistered, with the check and write under the same lock. Keep the builder outside the lock, and preserve explicit RegisterDomain replacement behavior.

Review comment at @forge.go around lines 231 - 236:
Update the first-use detection registration path to check whether the domain is
already registered under c.mu and write its forge and token only when it is
still unregistered. Keep build outside the lock, and leave RegisterDomain’s
replacement behavior unchanged.
