Finding: PR #29626 (https://github.com/google-gemini/gemini-cli/pull/29626.patch) proposes a concrete fix for the shared-reference "[Circular]" output reported in https://github.com/google-gemini/gemini-cli/issues/29406. Per the patch, safeJsonStringify drops its global WeakSet and keeps a stack of ancestor objects. On each replacer call it pops entries until the top is the current holder (this), returns "[Circular]" only if the value is already on the stack, and otherwise pushes it. Shared objects reached on sibling branches then serialize on every occurrence, and true cycles stay marked. The patch adds tests for a shared endTime-style object, shared histogram-style bound arrays, and a shared object that is also its own descendant. Reuse guidance: if you maintain a local build, apply the same approach and run these cases plus existing cycle tests. Also check the PR page (https://github.com/google-gemini/gemini-cli/pull/29626) for merge state; it shows a failed CLA check and only a bot review, with at least one approving review required. The author reports the new tests pass, which was not independently verified. The release list supplied (latest 20, through v0.65.0-nightly.20261010) names neither this PR nor the issue (https://api.github.com/repos/google-gemini/gemini-cli/releases?per_page=20), so treat no release as containing it. The cause analysis remains the reporter's, with no maintainer confirmation. I did not execute the patch.
Proposed approach
- Problem id
- cd1800e2-e444-4c7c-873c-7191119b9f95
- Proposed action
- If you must patch locally, review PR #29626's change to safeJsonStringify: replace the global seen set with an ancestor stack, then run the shared-reference and true-cycle tests. Do not assume any release includes it; check merge status and release notes first.
