fix(gl): truncate node-supplied display strings at a char boundary (#350) - #460
beardthelion wants to merge 2 commits into
Conversation
…itlawb#350) Every timestamp/id/SHA the CLI prints was cut with &s[..N] or &s[..N.min(s.len())]. The first panics on a short value, the second still panics when byte N is inside a multi-byte char. A shared text::truncate cuts at a char boundary and covers all sites, including two the issue did not name (node events, agent did) and the same shape in bounty, changelog, ipfs pin listing, and the merge-commit print.

Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~15 minutes Change: Bug fix · Severity of issue fixed: Low Merge Risk: ⚪ Minimal · up to This change replaces fixed-width string slicing with a safe, UTF-8-boundary-aware truncation helper used across CLI display output. The core helper logic was checked and correctly handles short, empty, and multibyte inputs without panicking, so this is ready to merge without known blocking risk. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Greptile SummaryThis PR centralizes truncation of node-supplied display strings and replaces panic-prone direct UTF-8 slicing across
Confidence Score: 4/5The PR appears safe to merge, with a non-blocking correction recommended so truncation actually honors its documented byte limit. The panic-prone slices are consistently replaced and regression-tested, but multibyte values can exceed the requested byte length because the helper counts Unicode characters. Files Needing Attention: crates/gl/src/text.rs

| Filename | Overview |
|---|---|
| crates/gl/src/text.rs | Adds the shared UTF-8-safe helper, but its character-count semantics do not enforce the promised byte limit. |
| crates/gl/src/issue.rs | Replaces unsafe timestamp and author slicing and adds focused malformed-timestamp regression coverage. |
| crates/gl/src/pr.rs | Replaces unsafe slicing for authors, reviewers, timestamps, and merge hashes with the shared helper. |
| crates/gl/src/repo.rs | Uses the shared helper for repository dates, replica dates, commit hashes, and commit dates. |

- Around line 9-10: The truncate helper currently limits characters instead of
bytes. In crates/gl/src/text.rs lines 9-10, update truncate to begin at
max.min(s.len()), move backward to a UTF-8 char boundary, and slice there;
update its documentation to describe byte limits. In crates/gl/src/text.rs lines
35-36, update the multibyte 10-byte test expectation to "2026-08-1".

Address PR review feedback: char_indices().nth(max) capped characters, so a multibyte char near the cut could exceed the byte limit. Start at max.min(len) and walk back to the nearest char boundary instead.

Summary
glslices node-supplied strings with&s[..10](and&s[..n.min(s.len())]variants) when rendering timestamps and identifiers inissue list,issue comments,pr list,node list,agent list,bounty list,changelog,ipfs,repo, andcertoutput. A timestamp shorter than 10 bytes, or one whose tenth byte falls mid-character, panics the CLI on data any node can return.Motivation & context
Closes #350
Kind of change
What changed
crates/gl/src/text.rswithtruncate(s, n): returns at mostnbytes, cut at a UTF-8 char boundary, so short and multibyte inputs render instead of panicking.text::truncate, including themin(len)variants which still panic on a char boundary.mcp.rs's four-byte parse is untouched: it is length-guarded and operates on a byte buffer, not a display string.How a reviewer can verify
The new test drives
gl issue listagainst a mock node returning short ("2026"), empty, and mid-char-boundarycreated_atvalues. Run against the old slice expression it panics atissue.rs:246(verified by reverting); on this branch it passes.Before you request review
