fix(gl): make doctor exit non-zero on Fail-class checks (#357) - #547
gl doctor printed per-row ✓/⚠/✗ status and the Some checks failed prose, but its exit code was always 0. A diagnostic whose exit status cannot express failure is a trap waiting for the first gl doctor && ... to land somewhere it shouldn't (#357).
Continues #391 (the commits are carried over unchanged; main was merged in as a separate commit, with one conflict in doctor.rs resolved by keeping the extracted gitlawb_node_env_check helper, which already contains the loopback handling added on main).
Scripts and CI read gl doctor's exit code to decide whether a machine is usable; printing failures while exiting 0 made that contract a lie.
Kind of change
Bug fix
What changed
Re-tier GITLAWB_NODE unset from Fail to Warn. The CLI's --node flag defaults to https://node.gitlawb.com (PUBLIC_NODE) and the CLI works fine without the env var, so an unset env is advisory, not a failure. Without this re-tier the obvious "return non-zero on any failure" change would have flipped gl doctor to exit 1 on a stock working install, which is exactly the regression the issue warns against.
Route the exit-code decision through a new has_failures(&[Check]) helper: exit 1 if and only if at least one row is Fail-class. Warn-class rows (iCaptcha offline, version drift, shell-alias shadowing, GITLAWB_NODE unset) keep the process at exit 0. Use std::process::exit(1) directly rather than returning Err so anyhow's error frame does not duplicate the user-facing summary that already prints.
Unit tests pin the new predicate against the three regimes: all-Ok, warn-only, and a single Fail row tripping the exit. The warn-only case is the regression guard for the re-tier: if anyone flips GITLAWB_NODE back to Fail, exit_predicate_is_false_for_warn_only fails too, so the two halves of the fix cannot drift apart. A binary probe test (tests/doctor_exit.rs) runs the real binary end to end so the exit-code wiring itself cannot be gutted silently.
Why these tiers
Per the issue, the Fail-class checks are: identity missing or unparseable, registration missing or malformed, node unreachable or non-2xx, git-remote-gitlawb absent, git absent. The Warn-class checks are: iCaptcha reachability, shell-alias shadowing, version drift, and now GITLAWB_NODE unset.
How a reviewer can verify
cargo test -p gl
cargo test -p gl doctor::
cargo test -p gl --test doctor_exit
Before you request review
Scope is one logical change; no unrelated churn
cargo test --workspace passes locally
New behavior is covered by tests (required for fixes)
cargo fmt --all and cargo clippy --workspace --all-targets -- -D warnings are clean
Commit titles use Conventional Commits (feat(...), fix(...), docs(...))
Docs / .env.example updated if behavior or config changed (or N/A)
Checked existing PRs so this isn't a duplicate
Protocol & signing impact
Touches DID / did:key, Ed25519 / RFC 9421 signatures, UCAN, ref certs, or P2P wire formats
Discussed in an issue before implementation
Backward-compatible with existing nodes and previously signed history
The first box is left unchecked: this is a CLI diagnostic exit code, which touches no signing surface or wire format.
Notes for reviewers
The GITLAWB_NODE re-tier is the load-bearing half, not a detail: without it, exit-on-any-fail would break every stock install that relies on the --node default.
Summary by CodeRabbit
Bug Fixes
gl doctor now exits with a failure status when any check fails; warning-only results exit successfully.
Results distinguish failures from warnings, and the guided-setup prompt appears only when failures are found.
Unset or empty node settings are reported as warnings, while configured loopback and nonempty node URLs pass their environment checks.
Empty or whitespace-only node URLs use the public node for connectivity checks, and results display the effective URL.
gl doctor printed per-row status and 'Some checks failed' prose, but its
exit code was always 0. A diagnostic whose exit status cannot express
failure is a trap waiting for the first 'gl doctor && ...' to land
somewhere it should not (#357).
Three changes:
1. Re-tier the 'GITLAWB_NODE unset' check from Fail to Warn. The CLI's
--node flag defaults to https://node.gitlawb.com (PUBLIC_NODE) and the
CLI works fine without the env var, so an unset env is advisory, not
a failure. Without this re-tier the obvious 'return non-zero on any
failure' change would have flipped gl doctor to exit 1 on a stock
working install, which is exactly the regression the issue warns
against.
2. Route the exit-code decision through a new has_failures(&[Check])
helper: exit 1 if and only if at least one row is Fail-class.
Warn-class rows (iCaptcha offline, version drift, shell-alias
shadowing, GITLAWB_NODE unset) keep the process at exit 0 because
those conditions are still printed to the user and the obvious
'&& pipeline' pattern stays valid. Use std::process::exit(1) rather
than returning Err so anyhow's error frame does not duplicate the
user-facing summary that already prints.
3. Three unit tests pin the new predicate against the three regimes:
all-Ok, warn-only, and a single Fail row tripping the exit. The
warn-only case is the regression guard for the re-tier: if anyone
flips GITLAWB_NODE back to Fail, exit_predicate_is_false_for_warn_only
fails too, so the two halves of the fix cannot drift apart.
Verified end-to-end against the public gitlawb node:
* unset GITLAWB_NODE, missing identity/registration -> exit 1
* unset GITLAWB_NODE, full healthy install -> exit 0 (warn)
* missing git-remote-gitlawb -> exit 1
- Extract GITLAWB_NODE env classification into gitlawb_node_env_check()
so unit tests can pin the Warn tier directly; the previous
has_failures-only tests built their own Check::warn rows and could not
see a re-tier back to Fail.
- Add three unit tests for the extracted helper (unset/empty is Warn,
set is Pass, loopback is Pass).
- Add integration probe crates/gl/tests/doctor_exit.rs that drives the
real binary with a temp --dir and --node http://127.0.0.1:1 and asserts
exit 1. Deleting the std::process::exit(1) gate keeps the unit suite
green but breaks this probe, closing the gap reviewer noted.
Co-authored-by: review fix for #391
gl doctor now exits with status 1 when any check fails. Unset or empty GITLAWB_NODE values produce warnings. The node probe uses the public node for blank URLs and reports the effective URL. Warning-only and all-passing runs exit with status 0.
Changes: Doctor check results
Layer / File(s)
Summary
Check classification and failure detection crates/gl/src/doctor.rs
Unset or empty GITLAWB_NODE values now produce warnings. Loopback and nonempty values pass. A shared predicate identifies failed checks.
Blank node URLs resolve to the public node. Success and error details identify the effective probe URL.
Result reporting and exit status crates/gl/src/doctor.rs, crates/gl/tests/doctor_exit.rs
The summary distinguishes failures from warning-only results, and the guided-setup prompt appears only when checks fail. The command exits with status 1 when any check fails. Unit and binary-level tests cover classification and exit behavior.
The current warning-only behavior appears correct, but a binary regression test would help ensure warnings continue to exit successfully. This gap does not block merging.

Explanation
The title "fix(gl): make doctor exit non-zero on Fail-class checks (#357)" names the main change: gl doctor now exits 1 when any Fail-class check fails. It follows Conventional Commits and is specific and concise. The title is a single sentence and the changeset matches it: the exit-code predicate, the GITLAWB_NODE re-tier to Warn, and the binary-level exit test all serve this change.
Full details: Description check
Explanation
The description follows the repository template. It includes a Summary, Motivation & context with a Closes #357 link, Kind of change with Bug fix checked, What changed with concrete numbered items naming the crate and files, reviewer verification commands, the Before you request review checklist, and the Protocol & signing impact section with a justified unchecked box. The Notes for reviewers section is filled in. The description is detailed and specific. The only gap is that the template's comment asks that the crate touched be noted; the description implies gl through the commands and title but does not name the crate in the What changed list explicitly. This is a minor gap, so the description is mostly complete.
Full details: Linked Issues check
Explanation
[#357] Exit gate: run() calls has_failures(&checks) and calls std::process::exit(1) when it returns true. has_failures() matches only CheckState::Fail. Fail-class checks keep Check::fail: identity, registration, node unreachable or non-2xx, git-remote-gitlawb absent, and git absent. These hunks are unchanged in the whole-PR diff. [#357] GITLAWB_NODE re-tier: gitlawb_node_env_check(None) and Some("") return Check::warn. Loopback and non-empty values return Check::pass. Unit tests gitlawb_node_env_unset_is_warn, gitlawb_node_env_set_is_pass, and gitlawb_node_env_loopback_is_pass cover this. [#357] Warn-class checks stay non-fatal: iCaptcha, version drift, and shell-alias shadowing remain Check::warn. Unit test exit_predicate_is_false_for_warn_only covers this. Binary test crates/gl/tests/doctor_exit.rs runs the real binary with no identity, an unreachable node, and GITLAWB_NODE removed, and asserts exit code 1. Limits: the incremental diff from previous reviewed head could not be read because changed blobs were missing. This assessment uses the whole-PR diff from merge base to head. The tests were not executed. Minor observation, not a requirement failure: gitlawb_node_env_check treats whitespace-only GITLAWB_NODE as Pass, while effective_node_url normalizes it for the probe. The doc comment says check 3 groups empty with unset, which is true only for the empty string. No exit-code effect follows, because the probe dials PUBLIC_NODE and the env row is Ok.
Full details: Out of Scope Changes check
Explanation
All whole-PR changes trace to #357. Changed files are crates/gl/src/doctor.rs and the new crates/gl/tests/doctor_exit.rs. In doctor.rs: all_ok is replaced by has_failures(), which drives both the prose selection and the exit gate. The GITLAWB_NODE check is extracted to gitlawb_node_env_check() so its Warn tier can be unit-tested. Its hint uses the PUBLIC_NODE constant. The new effective_node_url() normalizes empty or whitespace-only node values for the connectivity probe. It supports #357 because, without it, an empty GITLAWB_NODE would bind args.node to an empty URL, the node check would Fail, and the exit code would become 1 for an env row that only Warns. The module doc comment is updated for the re-tier. The new unit tests and the binary test support the exit-code objective. No hunks change check_version, the shell-alias check, or other #197 / PR #198 code. Non-code note: the PR description names the default node as https://node.gitlawb.com, while PUBLIC_NODE and the module doc name node.twigpine.com. This is a description inaccuracy and does not change any scope or requirement outcome.

Merge readiness
Checks: Required jobs largely green on the latest push (fmt + clippy, build --release, MSRV, Windows non-blocking, cargo audit). Some matrix jobs were still pending when this review ran; treat full test (stable) / test (beta) / Docker smoke as the merge gate.
Reviews:mergeStateStatus is BLOCKED pending human approval. CodeRabbit left one actionable inline on the default-node hint (same defect as the finding below).
Duplicate work: PR #391 (same title) is closed; this branch continues that work with a main merge. No duplicate open PR found for #357.
Bot nits: CodeRabbit “docstring coverage” on new helpers is advisory unless the repo enforces it in required CI.
Drift and scope audit
Reviewer challenge: whether findings are real, in scope, or pre-existing / scope drift.
#357 exit wiring (has_failures, process::exit(1), Warn stays exit 0): Verified on head. No finding — matches issue intent; not pre-existing debt. Missing warn-only binary probe was considered and withdrawn (unit tests + helper tests satisfy #357; no demonstrated head failure).
Operator URL (below):Real and in scope. Wrong host string is introduced by this diff at re-tier time; merge-base Fail hint already used https://node.twigpine.com (git show 61d8a4f8:crates/gl/src/doctor.rs). Not a request to fix repo-wide gitlawb.com in bootstrap/infra (pre-existing split) — only surfaces this PR changed in doctor.rs.
Module check-3 line: Wording unchanged on both sides of the diff but made inaccurate by this PR’s Fail→Warn change; fixing it with the hint is in scope, not a docs sweep.
Withdrawn as drift or out of scope: workspace PUBLIC_NODE realignment, process::exit in async main, install-script exit semantics (intended behavior change per #357), cargo test -p gl doctor:: not selecting doctor_exit.rs.
Findings
🟡 P2 — Align GITLAWB_NODE operator copy with PUBLIC_NODE on every surface this PR touched
At merge-base the Fail-tier hint correctly used https://node.twigpine.com; this PR regressed that string when re-tiering to Warn.
🔎 Root cause: The re-tier and new comments cite node.gitlawb.com, but the authoritative default in this file is PUBLIC_NODE (node.twigpine.com). Operator surfaces in the same PR were not kept in sync.
📜 Stated contract:
PUBLIC_NODE is https://node.twigpine.com and is the DoctorArgs.node default when GITLAWB_NODE is unset.
🏷️ Attribution:PR-introduced regression on the fix hint (verified vs merge-base); PR-activated inaccuracy on unchanged module check-3 text once unset env became Warn (#357).
Inline comments claiming --node defaults to https://node.gitlawb.com
Module doc line still describing check 3 as requiring a set non-localhost GITLAWB_NODE (no longer true after Warn tier)
🔒 Unchanged on main: Every other gl subcommand’s default_value = "https://node.twigpine.com" pattern — do not rebrand the workspace in this PR.
🔧 Required correction: Drive the export suggestion from PUBLIC_NODE (or the same literal) and rewrite comments + module check-3 text to match Warn-on-unset semantics and the twigpine default, e.g.:
format!("export GITLAWB_NODE={PUBLIC_NODE}")
Add a unit assertion that the unset/empty warn fix contains PUBLIC_NODE if helpful.
🛠️ Author fix: Fix every row under In this PR in one pass — hint, comments, and module header — without editing unrelated crates or bootstrap peer docs.
🚫 Out of scope: Replacing PUBLIC_NODE workspace-wide with node.gitlawb.com, or changing bootstrap peer URLs in infra files; adding subprocess exit-0 probes beyond what #357 already tests in unit tests.
Stale URL fixed in f9c661b: the GITLAWB_NODE Warn hint now builds from PUBLIC_NODE (format!("export GITLAWB_NODE={PUBLIC_NODE}")) so it cannot drift again, the comments name node.twigpine.com, and the doctor tests pass locally.

Fix stays inside doctor.rs (normalize empty/whitespace probe URL via PUBLIC_NODE); not a repo-wide URL rebrand.
Issue-only scope note: GitHub #357 names unset stock installs, not GITLAWB_NODE="". The remaining finding binds this PR’s in-diff copy and gitlawb_node_env_unset_is_warn (Some("")). Dropping empty from tests/copy would remove the stated contract for that item; keeping empty≡unset obliges aligning check 4.
Withdrawn as drift or out of scope: warn-only binary exit-0 probe mandate, process::exit in async run, workspace PUBLIC_NODE rebrand, whitespace-only env URL validation, check-3 vs --node override semantics (pre-existing clap).
Findings
🟡 P2 — Empty GITLAWB_NODE must match unset for Warn tier and node probe
💥 What fails: On an otherwise healthy doctor run, unset vs exported-empty env diverge on the node row and exit code.
Unset:
Check 3: Warn
Check 4: probes https://node.twigpine.com (clap default_value when the variable is absent)
GITLAWB_NODE="":
Check 3: Warn (this PR treats Some("") like unset)
Check 4: args.node is "" → Fail (unreachable: GET /) → exit 1
So a warn-only-shaped install for unset (exit 0) is not achievable for empty when connectivity would succeed with the public default.
🔎 Root cause: This PR aligns check 3 for None and Some("") but does not apply the same effective URL to check 4; clap still supplies "" when the env var is present and empty.
📜 Stated contract:
PR description: "Unset or empty GITLAWB_NODE values are reported as warnings rather than failures."
gitlawb_node_env_unset_is_warn pins gitlawb_node_env_check(Some("")) as CheckState::Warn.
(#357 itself requires unset advisory tier + exit 0 on stock installs; empty is this PR’s extension via the test and description above.)
🏷️ Attribution:PR-activated inconsistency. Merge-base: empty env was Fail on check 3; clap already set args.node to "" and the node row failed; exit was always 0. Head: empty is Warn on check 3 while check 4 behavior is unchanged; exit 1 when the node row fails.
📌 In this PR:
gitlawb_node_env_check_ arm (Warn for None and Some(""))
🔒 Unchanged on main: Whitespace-only or garbage non-loopback env strings still pass check 3 via !v.is_empty() without trim — do not expand into full URL validation in this PR.
🔧 Required correction: Before the node HTTP probe, treat an empty or whitespace-only effective URL like unset: use PUBLIC_NODE. Optionally distinguish operator copy for empty vs unset. Add regression coverage that empty env matches unset on check 4 and exit 0 on an otherwise healthy fixture.
let node_url = if args.node.trim().is_empty(){PUBLIC_NODE}else{
args.node.as_str()};let client = NodeClient::new(node_url,None);
🛠️ Author fix: Close every In this PR row in one pass — helper tier, connectivity target, and operator strings — without editing unrelated crates or rebranding URLs outside doctor.rs.
🚫 Out of scope: Repo-wide gitlawb.com vs twigpine.com cleanup, mandatory warn-only subprocess tests, replacing process::exit with Result, or fixing pre-existing check-3 vs --node override semantics.

Check 4: args.node is "" → Fail (unreachable: GET /) → exit 1
So a warn-only-shaped install for unset (exit 0) is not achievable for empty when connectivity would succeed with the public default.
🔎 Root cause: This PR aligns check 3 for None and Some("") but does not apply the same effective URL to check 4; clap still supplies "" when the env var is present and empty.
📜 Stated contract:
PR description: "Unset or empty GITLAWB_NODE values are reported as warnings rather than failures."
gitlawb_node_env_unset_is_warn pins gitlawb_node_env_check(Some("")) as CheckState::Warn.
(#357 itself requires unset advisory tier + exit 0 on stock installs; empty is this PR’s extension via the test and description above.)
🏷️ Attribution:PR-activated inconsistency. Merge-base: empty env was Fail on check 3; clap already set args.node to "" and the node row failed; exit was always 0. Head: empty is Warn on check 3 while check 4 behavior is unchanged; exit 1 when the node row fails.
📌 In this PR:
gitlawb_node_env_check_ arm (Warn for None and Some(""))
🔒 Unchanged on main: Whitespace-only or garbage non-loopback env strings still pass check 3 via !v.is_empty() without trim — do not expand into full URL validation in this PR.
🔧 Required correction: Before the node HTTP probe, treat an empty or whitespace-only effective URL like unset: use PUBLIC_NODE. Optionally distinguish operator copy for empty vs unset. Add regression coverage that empty env matches unset on check 4 and exit 0 on an otherwise healthy fixture.
let node_url = if args.node.trim().is_empty(){PUBLIC_NODE}else{
args.node.as_str()};let client = NodeClient::new(node_url,None);
🛠️ Author fix: Close every In this PR row in one pass — helper tier, connectivity target, and operator strings — without editing unrelated crates or rebranding URLs outside doctor.rs.
🚫 Out of scope: Repo-wide gitlawb.com vs twigpine.com cleanup, mandatory warn-only subprocess tests, replacing process::exit with Result, or fixing pre-existing check-3 vs --node override semantics.
Small housekeeping: my 03:37 UTC changes-requested review referred to me in the third person by mistake. Please use the latest changes-requested review on this head (same substance, first-person wording + drift audit). The 79d2285 URL finding remains resolved on f9c661be.
Check 3 groups an empty env with unset (Warn), but clap still binds
args.node to "" and the connectivity probe dialed it verbatim, so a
GITLAWB_NODE="" install showed a Fail row and exited 1. effective_node_url
normalizes empty or whitespace-only input to PUBLIC_NODE before the
probe so empty matches unset on check 4.
Empty-env case fixed in 9135f57: a set-but-empty GITLAWB_NODE binds args.node to "" through clap, so the connectivity probe now normalizes empty or whitespace-only input to PUBLIC_NODE via effective_node_url before dialing, matching what check 3 already groups with unset. A new unit test pins empty and blank inputs to PUBLIC_NODE, and the doctor tests pass locally.
The current binary fixture always has Fail-class checks. An exit gate that also treats warnings as failures could pass this test and the predicate tests.
Add a fixture with valid identity and registration, a reachable mock node, and available Git binaries. Leave GITLAWB_NODE unset, then assert a warning is present, no Fail-class checks are present, and the exit code is 0.

Merge readiness
Target drift: Branch head 9135f572 does not contain live main tip 0189990 (fix(node): bound federated repository aggregation (#546)). git merge-base HEAD origin/main is 61d8a4f8. Rebase (or merge current main) before merge so CI runs against the same base reviewers expect.
Review state:reviewDecision is CHANGES_REQUESTED from jatmn on f9c661be (empty-env probe + operator URL). Both items are addressed on 9135f572. Maintainer should dismiss or re-approve after confirming this head; merge remains blocked until GitHub review state clears.
Checks: Required PR Checks jobs on the latest push are green on metadata capture (fmt + clippy, test (stable|beta), build --release, MSRV, Docker smoke, Analyze (rust)). CodeQL Swift was still in progress when artifacts were captured — confirm it finishes green if your gate requires the full matrix.
PR description hygiene (optional): Body still names https://node.gitlawb.com as the default node in places; implementation uses PUBLIC_NODE (https://node.twigpine.com). Doc-only description edit, not a code defect.
Bot nits: CodeRabbit “warn-only binary test” and “docstring coverage” are advisory; not demonstrated production failures on this head.
Operator URL (prior jatmn / CodeRabbit): Fixed on f9c661be+ — hint uses format!("export GITLAWB_NODE={PUBLIC_NODE}"); no node.gitlawb.com in doctor.rs.
Empty GITLAWB_NODE vs unset on check 4: Fixed on 9135f572 via effective_node_url + effective_node_url_treats_empty_and_blank_as_unset.
Withdrawn as drift / out of scope: mandatory warn-only subprocess exit-0 probe; whitespace-only GITLAWB_NODE row-3 tier (pre-existing !v.is_empty() without trim, not bound by #357 or in-diff tests); workspace-wide URL rebrand; process::exit in async run (intentional per #357).

Summary
gl doctorprinted per-row✓/⚠/✗status and theSome checks failedprose, but its exit code was always 0. A diagnostic whose exit status cannot express failure is a trap waiting for the firstgl doctor && ...to land somewhere it shouldn't (#357).Continues #391 (the commits are carried over unchanged; main was merged in as a separate commit, with one conflict in
doctor.rsresolved by keeping the extractedgitlawb_node_env_checkhelper, which already contains the loopback handling added on main).Closes #357
Motivation & context
Scripts and CI read
gl doctor's exit code to decide whether a machine is usable; printing failures while exiting 0 made that contract a lie.Kind of change
What changed
Re-tier
GITLAWB_NODEunset from Fail to Warn. The CLI's--nodeflag defaults tohttps://node.gitlawb.com(PUBLIC_NODE) and the CLI works fine without the env var, so an unset env is advisory, not a failure. Without this re-tier the obvious "return non-zero on any failure" change would have flippedgl doctorto exit 1 on a stock working install, which is exactly the regression the issue warns against.Route the exit-code decision through a new
has_failures(&[Check])helper: exit 1 if and only if at least one row is Fail-class. Warn-class rows (iCaptcha offline, version drift, shell-alias shadowing, GITLAWB_NODE unset) keep the process at exit 0. Usestd::process::exit(1)directly rather than returningErrso anyhow's error frame does not duplicate the user-facing summary that already prints.Unit tests pin the new predicate against the three regimes: all-Ok, warn-only, and a single Fail row tripping the exit. The warn-only case is the regression guard for the re-tier: if anyone flips
GITLAWB_NODEback to Fail,exit_predicate_is_false_for_warn_onlyfails too, so the two halves of the fix cannot drift apart. A binary probe test (tests/doctor_exit.rs) runs the real binary end to end so the exit-code wiring itself cannot be gutted silently.Why these tiers
Per the issue, the Fail-class checks are: identity missing or unparseable, registration missing or malformed, node unreachable or non-2xx,
git-remote-gitlawbabsent,gitabsent. The Warn-class checks are: iCaptcha reachability, shell-alias shadowing, version drift, and nowGITLAWB_NODEunset.How a reviewer can verify
