fix(gl): derive View: URL from node instead of hardcoding gitlawb.com (#370)#377Gravirei wants to merge 10 commits into
Conversation
…Gitlawb#370) gl repo create and gl mirror print a View: link that was unconditionally pointed at gitlawb.com, which 404s for repos on self-hosted nodes. Make the node advertise an optional web_url on GET / (sourced from the new GITLAWB_WEB_URL env var). The CLI fetches GET / after repo creation and only prints View: when the node supplies web_url. Nodes without the config skip the line entirely, which is better than printing a broken link.

I read the diff on head 9ca4fcf, ran cargo test -p gl repo::tests::test_cmd_create_success (green, no View: because GET / is unmocked), and premise-mutated both sides: removing the server web_url insert left the full gitlawb-node suite green; removing the CLI View block or restoring the hardcoded gitlawb.com link also left test_cmd_create_success green. The core design is sound: stop hardcoding gitlawb.com, advertise web_url from the node, print View: only when present, trim trailing slashes on the CLI. CodeRabbit's normalization ask is already on head. I am declining their silent-omit ask: this matches the existing fail-soft pattern for optional post-success hints (repo.rs replica count).
One process note, not a finding: open PR #325 also touches crates/gitlawb-node/src/config.rs and is likely to land first. Expect a rebase conflict there, not a design rework.
Findings
-
[P2] Pin the View-URL behavior with load-bearing tests
crates/gl/src/repo.rs:838
test_cmd_create_success mocks only POST /api/v1/repos and never asserts stdout. Restoring the hardcoded gitlawb.com View line still passes. Add a mock GET / returning {"web_url":"https://example.com",...}, capture stdout, assert the View: line uses that base; add a case with no web_url (or failed GET /) asserting no View: and no gitlawb.com. Mirror should get the same treatment or share a small helper under test. -
[P2] Reject empty or whitespace-only GITLAWB_WEB_URL at boot
crates/gitlawb-node/src/config.rs:574
Clap maps GITLAWB_WEB_URL="" to Some("") not None, and the node advertises it whenever is_some(). Whitespace-only values produce a broken View: line. Add a Config::validate() check (trim, reject if empty) or normalize to None. -
[P3] Document GITLAWB_WEB_URL beside GITLAWB_PUBLIC_URL
.env.example:11
The struct field and clap help exist, but .env.example only documents GITLAWB_PUBLIC_URL. Operators need a one-line distinction: API reachability vs browser View base.
Not an ask, recorded only: gl peer add reading public_url from GET / is a pre-existing contract gap, not introduced here. Fleet deploy templates setting only GITLAWB_PUBLIC_URL means View links stay hidden until someone sets GITLAWB_WEB_URL separately; that is a deployment follow-up, not a blocker on this PR.
- Extract fetch_node_web_url() helper for testability; add 6 unit tests covering: web_url present, trailing-slash trim, absent, empty string, whitespace-only, and server error - Reject empty/whitespace-only GITLAWB_WEB_URL at boot in Config::validate() - Trim whitespace from web_url in the CLI helper (not just trailing slashes) - Document GITLAWB_WEB_URL in .env.example alongside GITLAWB_PUBLIC_URL - Mirror uses shared fetch_node_web_url() helper

…lawb#370) Both web_url validators now reject URLs carrying a query string or fragment: the CLI builds View links by string-appending /{owner}/{repo}, so "?a=1" would swallow the repo path into the query. The CLI also no longer swallows transport-level failures on GET / — a refused or failed connection warns on stderr like the other degraded-link paths.

Re-read head 57276ca. CI is green except cargo audit (fleet advisory). The #370 core is in place: nodes advertise optional web_url, the CLI prints View: only when present, and validate_web_url rejects empty, scheme-less, and non-http(s) values at boot. 57276ca also adds transport-error warnings on GET / and rejects query/fragment web_urls on both sides. I ran a rustc probe against validate_web_url: "https://git lawb.com" fails parse, but "https://example.com/\x1b[31m" still passes with control bytes in the stored string.
Open PRs #285, #324, #325, #173, and #330 also touch config.rs; expect a rebase conflict when those land, not a design rework.
Findings
- [P2] Cap and sanitize web_url before terminal output
crates/gl/src/repo.rs:249
fetch_node_web_url still calls info_resp.json().await on the full GET / body and returns the raw JSON string for println without sanitize_node_msg. peer.rs already treats caller-chosen node replies as the least trusted bytes in gl: read_body_capped(resp, 8 * 1024) then defang before the terminal (peer.rs:198-202, http.rs:209-236). A hostile node can pass http(s) url::Url parse with ANSI, bell, or bidi controls in the path; those bytes reach View: in both cmd_create and mirror.rs. Mirror the peer pattern here: cap the body, parse from the cap, run sanitize_node_msg on the accepted base before return/print, and add a unit test with control bytes in the mock web_url asserting they do not reach the returned string. The malformed-web_url stderr path should sanitize trimmed the same way.
Not an ask, recorded only: test_cmd_create_success still does not mock GET / or assert stdout; the helper unit tests cover #370 at the function level.
Superseded by review on head 57276ca
…#370) Treat GET / like every other caller-chosen node reply: bound the body read at 8 KiB and parse from the cap (peer.rs precedent). A web_url containing control or bidi characters — which passes URL parsing but would reach the terminal verbatim through the View: line — is now rejected as malformed, with a defanged preview in the warning.
h2 0.4.13 is vulnerable to unbounded empty DATA frames (remote DoS); 0.4.16+ carries the fix. Lockfile-only bump, no manifest change.

If a successful response has invalid JSON, or contains a present non-string web_url, this helper returns None silently. The command then looks the same as a node that correctly has no web frontend.

Re-read head 6c40812. CI is green. The cap-and-sanitize round from my last review is on head: fetch_node_web_url caps GET / at 8 KiB (read_body_capped), rejects C0 controls and bidi-format chars, and cargo test -p gl fetch_node_web_url is 11/11 green including test_fetch_node_web_url_rejects_control_bytes. Node boot validation, .env.example, and the shared helper wiring in mirror.rs all look right for #370.
One gap remains in the same terminal-safety class.
Findings
- [P2] Reject U+2028 and U+2029 in advertised web_url before printing View:
crates/gl/src/repo.rs:274
fetch_node_web_urlgates onis_control()andis_bidi_format(), but U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR are neither (rustc: bothis_control=false, not inis_bidi_format). I mocked GET / withweb_urlcontaining U+2028; the helper returnedSome("https://example.com/\u{2028}evil"), which would reachprintln!(" View: ...")in bothcmd_createandmirror.rs. Those code points break the terminal line the same way a newline would. Extend the rejection predicate to cover them and add a unit-test case; optionally mirror the same rule invalidate_web_urlat boot so the node does not advertise them on GET /.
One process note, not a finding: open PRs #285, #324, and #325 also touch crates/gitlawb-node/src/config.rs. Expect a rebase conflict when those land.
Not an ask, recorded only: I am declining CodeRabbit's warn-on-invalid-JSON thread again. A 200 with unparseable JSON is the same fail-soft contract as a missing web_url field for this optional hint. Node boot validate_web_url does not yet reject control/bidi bytes the client already blocks; defense in depth only, not blocking here. The read_body_capped call is present but not proven load-bearing by an oversized-body case in the helper tests; the implementation matches the peer.rs precedent.

Re-read head a6113fd after the main merge. CI is red workspace-wide: crates/gitlawb-node/src/config.rs is missing a closing } after web_url_rejects_non_absolute_or_non_browser_urls (~line 1529), so the next test nests inside it and the crate does not compile. I counted braces in mod tests: 47 open, 46 close. Prior head 6c40812 was green on the node web_url tests; this is a merge regression, not a logic revert.
When the tree compiles, the #370 core from my last round is still there: optional GITLAWB_WEB_URL with boot validation, GET / advertises it, fetch_node_web_url caps the body at 8 KiB, warns on transport/status/malformed advertisement, and rejects control/bidi bytes before any View: line. Query/fragment rejection is symmetric between node validate_web_url and the CLI helper.

[P2] Pin the #370 premise with a cmd_create integration test
crates/gl/src/repo.rs:904
test_cmd_create_successmocks onlyPOST /api/v1/reposand neverGET /. Ifcmd_createwent back to hardcodinghttps://gitlawb.comforView:, that test would still pass. The tenfetch_node_web_url_*tests cover the helper, not the command path. Add a test that mocks both routes: withweb_urladvertised, assert stdout containsView: https://.../{owner}/{name}; without it, assert noView:line. That is the load-bearing check for issue #370.
Not an ask, recorded only: CodeRabbit's two unresolved threads (warn on invalid JSON / non-string web_url; reject bidi in node validate_web_url) are reasonable polish. Invalid JSON on a 200 GET / is already fail-soft with no warning by design; bidi in operator config is trusted and the CLI already rejects bidi on the advertised value before print. Neither blocks merge once CI is green.
One process note, not a finding: rebase may conflict with #285/#324/#325 on config.rs; resolve against whichever of those merges first.
…with integration test The a6113fd merge onto Gitlawb#370 left the workspace red: a missing closing `}` in `web_url_rejects_non_absolute_or_non_browser_urls` so the next test nested inside it (config.rs), a duplicate `url = "2"` workspace dep (Cargo.toml, one from the redirect-rule PR, one from Gitlawb#370), and `fetch_node_web_url` derefing `CappedBody` as `&str` instead of `.text` (repo.rs, regression in the same merge). All three are straightforward to repair; the brace was the only one blocking CI. The new `cmd_create_view_url_tracks_node_advertisement` integration test drives the real `gl repo create` binary against a mockito node that answers both `POST /api/v1/repos` and `GET /`, and asserts the printed `View:` line tracks the advertised web_url — present with the advertised origin when set, absent when the node omits it. The helper-level `fetch_node_web_url_*` tests would still pass if `cmd_create` reverted to a hardcoded URL; this one would not, so it is the load-bearing check for Gitlawb#370.

I found issues that need to be addressed before this is ready.
Findings
-
[P2] Normalize the configured URL before advertising it
crates/gitlawb-node/src/config.rs:782validate_web_urlintentionally accepts surrounding whitespace by parsingraw.trim(), but it does not normalizeConfig.web_url. Bothnode_infoanddegraded_node_infothen serialize the original string. As a result,GITLAWB_WEB_URL=" https://git.example "starts successfully even thoughGET /advertises a value with leading/trailing whitespace rather than the valid absolute URL that was actually checked. The currentglhelper hides this inconsistency by trimming a second time, but any other node-info consumer that parsesweb_urldirectly can reject it or generate a broken browser link.Please fix the root cause at the configuration boundary: define one canonical representation for
web_url, store that normalized representation after validation, and use it for both normal and degraded node-info responses. Alternatively, reject any input that is not already canonical. Keep the existing support for valid HTTP(S) bases with paths and ports, and retain the CLI’s defensive validation for remote nodes. -
[P2] Reject credentials in advertised web URLs
crates/gitlawb-node/src/config.rs:790The new validation accepts URL userinfo because it only checks scheme, query, and fragment. For example,
https://user:secret@example.comis accepted asGITLAWB_WEB_URL; the node publishes that exact value from publicGET /, andfetch_node_web_urlreturns the original string for bothgl repo createandgl mirrorto print in theirView:lines. That exposes an accidentally configured password or token in public metadata, terminal scrollback, CI logs, and any captured command output.Please address this at the root cause by treating
web_urlas a credential-free browser origin/path, not an arbitrary HTTP URL. Reject URLs whose parsed representation contains a username or password during node startup validation, and enforce the same constraint when the CLI consumes an advertisement from a remote node. Add regression coverage for user-only and user-plus-password forms, and preserve support for ordinary host, port, and path base URLs.

Re-read head 4c48511. CI is 12/12 green. The merge-regression items from my last round are fixed: the config test module compiles, and cmd_create_view_url integration test pins the #370 premise (hardcoding gitlawb.com fails it RED). The core design still looks right: optional GITLAWB_WEB_URL, advertised on GET /, CLI prints View: only when present.
Two gaps remain at the configuration boundary before this can merge.
Findings

[P2] Store and advertise a canonical web_url
crates/gitlawb-node/src/config.rs:782
validate_web_urlvalidatesraw.trim()but leavesConfig.web_urlas the operator typed it.node_infoanddegraded_node_infothen serialize that raw string on publicGET /. I setweb_urlto" https://git.example "in a config test and validation passes while the advertised value still carries padding. The CLI trims again infetch_node_web_url, which hides the bug on the View line, but any other consumer that parsesweb_urldirectly gets a non-canonical base. Normalize to one stored form after validation (or reject non-canonical input outright) and use that everywhere you advertise it. -
[P2] Reject userinfo in web_url values
crates/gitlawb-node/src/config.rs:790
Validation checks scheme, query, and fragment only.https://user:secret@example.compasses boot, is published verbatim onGET /, andfetch_node_web_urlreturns the original string forView:output. That puts an accidentally configured password into public metadata, terminal scrollback, and CI logs. Treatweb_urlas a credential-free browser base: reject URLs with a username or password at node startup and in the CLI when consuming a remote advertisement. Add regression tests for user-only and user-plus-password forms.
Not an ask, recorded only: cmd_create_view_url.rs should call assert_async() on its mockito mocks when you touch tests again; the house pattern elsewhere in gl does.
… review) Two P2s from the Gitlawb#370 review addressed at the configuration boundary. `Config::validate()` now rewrites `self.web_url` to the canonical `url::Url::to_string()` after `validate_web_url` succeeds, so the regular and degraded `GET /` handlers advertise the same string that was actually validated instead of the operator-typed one. The CLI trims a second time in `fetch_node_web_url`, which hid the divergence on the View: line, but any other consumer parsing `web_url` directly would see a non-canonical base. `validate` is now `&mut self` to carry the write; the one non-test caller already binds `mut` and the two test bindings are updated to match. Both `validate_web_url` (node) and `fetch_node_web_url` (CLI) now reject URLs with a non-empty username or a password: the configured value is published on public `GET /` and reprinted on the View: line, so an accidentally configured `https://user:secret@example.com` would land in public metadata, terminal scrollback, and CI logs. New regression tests cover user-only and user+password forms on both sides, plus a normalization test that the stored value matches the canonical form (with and without operator padding).

Re-read head 10da6f6. CI is 12/12 green on this head. I ran cargo test -p gl fetch_node_web_url (12 pass), cargo test -p gl --test cmd_create_view_url (1 pass), and cargo test -p gitlawb-node web_url (3 pass). Premise mutation on cmd_create (hardcoded gitlawb.com instead of fetch_node_web_url) turned cmd_create_view_url_tracks_node_advertisement RED; restoring the fetch path turned it green again. Vacuity on the validate_web_url userinfo guard turned web_url_rejects_non_absolute_or_non_browser_urls RED.
jatmn's two P2s from 4c485112 are on head: Config::validate now rewrites web_url to the canonical url::Url::to_string() form, and both node boot validation and fetch_node_web_url reject userinfo. Normal and degraded GET / both emit the same post-validate string. web_url is browser metadata, not server egress, so skipping is_public_http_url is correct for self-hosted front-ends.
Open PRs #285, #325, and #324 will move config.rs before this lands; expect a rebase, not a design redo.
Not an ask, recorded only: node-side validate_web_url could mirror the CLI's control/bidi rejection so misconfigured GITLAWB_WEB_URL never publishes terminal-dangerous bytes on public GET / for non-CLI consumers. The View: path is already protected client-side.
Not an ask, recorded only: a 200 GET / with invalid JSON still omits View: without a stderr warning (transport and HTTP failures do warn). Cosmetic degrade, not a regression from #370.
Summary
gl repo create and gl mirror print a
View:link unconditionally pointed atgitlawb.com, which 404s for repos on self-hosted nodes.Motivation & context
Closes #370
After
gl repo createon a self-hosted node, theView:URL resolves throughgitlawb.com→explorer.gitlawb.com, which can only see repos on the main network. Self-hosted repos silently 404. The fix lets nodes advertise an optionalweb_urlso the CLI only prints a working link.Kind of change

When set, the node advertises it inGET /.node_infoconditionally includesweb_urlin the response.DegradedState,build_degraded_router,run_degraded_server, anddegraded_node_infopropagate and includeweb_url.GET /and only printsView:when the node suppliesweb_url.View:whenweb_urlis present.How a reviewer can verify

Notes for reviewers
web_urlis entirely opt-in: nodes that don't setGITLAWB_WEB_URLomit it fromGET /, and the CLI silently skips theView:line. No behavior change for existing deployments.GET /endpoint is already public (no auth), consistent with how node identity info is served.Summary by CodeRabbit
