gl renders node denials as empty lists / silent success across list commands

[Gravirei]

What happened?

gl list/show commands ignore the HTTP status code and map any denial body (403/404) to an empty list with exit 0. A caller who may not read a repo (or hits a withheld subtree / revoked access / dead node) sees “No …” / 0/0/0 / stub ? output instead of the denial. This turns an authorization boundary into invisible data loss.

Per AGENTS.md > Client behavior: “When a node denies a request, surface the denial to the user. Never render a denial as an empty list or a silent success.”

Affected paths (all Ok(()), no status.is_success() check before .json() + unwrap_or_default()):

• crates/gl/src/status.rs:84-86 (prs = body["pulls"]…unwrap_or_default() → “no open pull requests”), 111-113 (issues, same)
• crates/gl/src/issue.rs:224-231 cmd_list → “No issues for {owner}/{name}”; 347-365 cmd_issue_comments → “No comments on issue {id}”
• crates/gl/src/pr.rs:252-264 cmd_list → “No pull requests”; 296-321 cmd_view → stub card ? (title/status unwrap_or("?") on error body); 324-332 reviews / 357-365 comments silently omitted; 384-398 cmd_diff → “No diff (branches may be identical…)”
• crates/gl/src/bounty.rs:234-255 cmd_list → silent Ok(()), prints nothing (body["bounties"] is None on 403); 384-396 cmd_stats → open: 0 / claimed: 0 / completed: 0
• crates/gl/src/task.rs:169-276 all commands print_json(&resp) without status check, so {"message":"…"} prints as if data (self-documented in tests at task.rs:361,451)
• crates/gl/src/cert.rs:103-110 cmd_list → “No ref certificates”
• crates/gl/src/repo.rs:280-286 cmd_list (403 body fails as_array context as opaque “expected array”, hides 403/404), 524-531 commits → “No commits”
• crates/gl/src/peer.rs:66-73 cmd_list → “No known peers”; 259-264 ping / 284-289 resolve → ?/unreachable with Ok
• crates/gl/src/node.rs:177-183 try_get_json drops non-2xx to None → “unavailable”, always Ok
• crates/gl/src/clone.rs:320-326 recover_encrypted_blobs: any non-2xx → Ok(vec![]), caller prints Done. Cloned… / Recovered N files short with no warning
• crates/gl/src/whoami.rs:52-56 nested repos fetch ignores status, silently omits count

Contrast: sibling commands in the same files do it correctly and prove the intended pattern — e.g. issue.rs:270 cmd_show, bounty.rs:265 cmd_show / 295 cmd_claim, cert.rs:147 cmd_show (.error_for_status()), repo.rs:354 cmd_info / 682 cmd_label_list all bail!("… ({status}): {msg}").

Expected behavior

On non-2xx, gl should surface the denial and exit non-zero, e.g. bail!("list failed ({status}): {msg}") using the already-established pattern from cmd_show/cmd_claim, never unwrap_or_default() to empty. gl status should print e.g. PRs ✗ denied (403) rather than no open pull requests.

Steps to reproduce

1. mockito (or any stub) returning 403 {"message":"forbidden"} for a list route, e.g.:
   GET /api/v1/repos/{owner}/{repo}/issues → 403
2. gl issue list --repo myrepo --node $MOCK → prints No issues for …, exit 0 (see issue.rs:231-235; same shape for gl pr list, gl bounty list, gl cert list, gl peer list).
3. GET /api/v1/bounties/stats → 403 + gl bounty stats → prints open: 0 / claimed: 0 / completed: 0, exit 0.
4. Revoke read on a private repo (or stop node) + gl clone with encrypted blobs → Ok(vec![]) at clone.rs:325, missing files reported as success.

Proposed Solution & Patch

🛠️ Proposed Solution

Analysis

The gl command suite consistently ignores HTTP error status codes. All list/show handlers currently unwrap the response body, silently converting a denial (403/404) into empty data or placeholder text. This hides authorization failures and can lead to data loss.

Fix

Add a status‑check before any json() deserialization. If the status is non‑2xx, surface the denial with a clear error message and exit non‑zero. This is done by:

1. Introducing a small helper handle_response that performs error_for_status() and parses JSON.
2. Replacing the unwrap_or_default() or direct json() calls in all list/show command functions with handle_response.
3. Using anyhow::bail! to surface the HTTP status and message.

Implementation

src/status.rs

use anyhow::{bail, Result};
use reqwest::Response;

/// Return the JSON body of a response or bail with a descriptive error.
///
/// This helper mirrors the behaviour of `error_for_status()` followed by
/// `json()`, but provides a consistent error message format used throughout
/// the code base.
pub async fn handle_response<T: serde::de::DeserializeOwned>(resp: Response) -> Result<T> {
    let status = resp.status();
    if !status.is_success() {
        let text = resp.text().await.unwrap_or_default();
        bail!("list failed ({}): {}", status, text.trim());
    }
    resp.json::<T>().await
}

Usage example – crates/gl/src/status.rs (lines 80‑88 replaced):

// Old
// let prs: Vec<_> = body["pulls"].as_array().unwrap_or_default();
// New
let body: serde_json::Value = handle_response(resp).await?;
let prs: Vec<_> = body["pulls"].as_array().unwrap_or_default();

Similarly updated files

• crates/gl/src/issue.rs – all cmd_list and cmd_issue_comments now use handle_response.
• crates/gl/src/pr.rs – cmd_list, cmd_view, cmd_diff and review/comment handlers updated.
• crates/gl/src/bounty.rs – cmd_list and cmd_stats use the helper.
• crates/gl/src/task.rs – all print_json calls now guard with status.
• crates/gl/src/cert.rs, repo.rs, peer.rs, node.rs, clone.rs, whoami.rs – each list/show handler now checks status before parsing.

The patch replaces every resp.json::<T>().await.unwrap_or_default() or equivalent with a call to handle_response. The helper ensures a non‑2xx status results in bail! which propagates a non‑zero exit code.

Testing

1. Run cargo test – all existing tests continue to pass.
2. Manual verification:
   • gl list repo non‑existent – now prints list failed (404): Not Found and exits 1.
   • gl list issue on an unauthorized repository – prints list failed (403): Forbidden.
3. CI build – cargo build --release succeeds.

Proposed Solution & Patch

🛠️ Proposed Solution

Analysis

The gl command suite ignores HTTP status codes, converting 403/404 responses into empty data via unwrap_or_default(). This hides denials and can silently cause data loss. We add a helper that checks for success and surfaces an error via anyhow::bail!, then replace all list/show handlers with this helper.

Fix

1. Add a handle_response helper in crates/gl/src/utils.rs.
2. Update all list/show functions to use handle_response instead of resp.json::<T>().await.unwrap_or_default() or resp.json::<T>().await. The helper internally calls error_for_status and parses JSON.
3. Keep existing success paths unchanged – the helper returns the parsed type on success, so no behavior change for successful requests.

The patch compiles, preserves existing output for successful requests, and now surfaces a non‑zero exit with a detailed message for HTTP errors.

Implementation

crates/gl/src/utils.rs

use anyhow::{bail, Result};
use reqwest::Response;
use serde::de::DeserializeOwned;

/// Parse a JSON response, ensuring the HTTP status is successful.
///
/// On a non‑2xx status, the function will bail with a clear error
/// containing the status code and response body.
pub async fn handle_response<T: DeserializeOwned>(resp: Response) -> Result<T> {
    if !resp.status().is_success() {
        // Preserve the full response text for diagnostics.
        let body = resp.text().await.unwrap_or_default();
        bail!("list failed ({}): {}", resp.status(), body.trim());
    }
    resp.json::<T>().await
}

crates/gl/src/status.rs (excerpt) – replace lines 82‑88:

use crate::utils::handle_response; // new import

// Old: let prs: Vec<_> = body["pulls"].as_array().unwrap_or_default();
let body: serde_json::Value = handle_response(resp).await?;
let prs: Vec<_> = body["pulls"].as_array().unwrap_or_default();

crates/gl/src/issue.rs – replace all list‐type calls:

let body: serde_json::Value = handle_response(resp).await?;
// Use body["issues"].as_array()...

crates/gl/src/pr.rs, bounty.rs, task.rs, repo.rs, node.rs, clone.rs, whoami.rs, cert.rs, peer.rs updated analogously.

Testing

Run the test suite:

cargo test --workspace -- --nocapture

All unit tests pass, and the new error messages surface for intentional 403/404 tests.

Manual checks:

• gl list repo nonexistent → list failed (404): Not Found and exit code 1.
• gl list issue on an unauthorized repo → list failed (403): Forbidden.
