feat(sync): pull-first sync with 3-way merge (#918)
* feat(sync): implement pull-first synchronization strategy - Add --pull-first flag and logic to sync command - Introduce 3-way merge stub for issue synchronization - Add concurrent edit tests for the pull-first flow Ensures local changes are reconciled with remote updates before pushing to prevent data loss. * feat(sync): implement 3-way merge and state tracking - Implement 3-way merge algorithm for issue synchronization - Add base state storage to track changes between syncs - Add comprehensive tests for merge logic and persistence Ensures data consistency and prevents data loss during concurrent issue updates. * feat(sync): implement field-level conflict merging - Implement field-level merge logic for issue conflicts - Add unit tests for field-level merge strategies Reduces manual intervention by automatically resolving overlapping updates at the field level. * refactor(sync): simplify sync flow by removing ZFC checks The previous sync implementation relied on Zero-False-Convergence (ZFC) staleness checks which are redundant following the transition to structural 3-way merging. This legacy logic added complexity and maintenance overhead without providing additional safety. This commit introduces a streamlined sync pipeline: - Remove ZFC staleness validation from primary sync flow - Update safety documentation to reflect current merge strategy - Eliminate deprecated unit tests associated with ZFC logic These changes reduce codebase complexity while maintaining data integrity through the robust structural 3-way merge implementation. * feat(sync): default to pull-first sync workflow - Set pull-first as the primary synchronization workflow - Refactor core sync logic for better maintainability - Update concurrent edit tests to validate 3-way merge logic Reduces merge conflicts by ensuring local state is current before pushing changes. * refactor(sync): clean up lint issues in merge code - Remove unused error return from MergeIssues (never returned error) - Use _ prefix for unused _base parameter in mergeFieldLevel - Update callers to not expect error from MergeIssues - Keep nolint:gosec for trusted internal file path * test(sync): add mode compatibility and upgrade safety tests Add tests addressing Steve's PR #918 review concerns: - TestSyncBranchModeWithPullFirst: Verifies sync-branch config storage and git branch creation work with pull-first - TestExternalBeadsDirWithPullFirst: Verifies external BEADS_DIR detection and pullFromExternalBeadsRepo - TestUpgradeFromOldSync: Validates upgrade safety when sync_base.jsonl doesn't exist (first sync after upgrade) - TestMergeIssuesWithBaseState: Comprehensive 3-way merge cases - TestLabelUnionMerge: Verifies labels use union (no data loss) Key upgrade behavior validated: - base=nil (no sync_base.jsonl) safely handles all cases - Local-only issues kept (StrategyLocal) - Remote-only issues kept (StrategyRemote) - Overlapping issues merged (LWW scalars, union labels) * fix(sync): report line numbers for malformed JSON Problem: - JSON decoding errors when loading sync base state lacked line numbers - Difficult to identify location of syntax errors in large state files Solution: - Include line number reporting in JSON decoder errors during state loading - Add regression tests for malformed sync base file scenarios Impact: - Users receive actionable feedback for corrupted state files - Faster troubleshooting of manual configuration errors * fix(sync): warn on large clock skew during sync Problem: - Unsynchronized clocks between systems could lead to silent merge errors - No mechanism existed to alert users of significant timestamp drift Solution: - Implement clock skew detection during sync merge - Log a warning when large timestamp differences are found - Add comprehensive unit tests for skew reporting Impact: - Users are alerted to potential synchronization risks - Easier debugging of time-related merge issues * fix(sync): defer state update until remote push succeeds Problem: - Base state updated before confirming remote push completion - Failed pushes resulted in inconsistent local state tracking Solution: - Defer base state update until after the remote push succeeds Impact: - Ensures local state accurately reflects remote repository status - Prevents state desynchronization during network or push failures * fix(sync): prevent concurrent sync operations Problem: - Multiple sync processes could run simultaneously - Overlapping operations risk data corruption and race conditions Solution: - Implement file-based locking using gofrs/flock - Add integration tests to verify locking behavior Impact: - Guarantees execution of a single sync process at a time - Eliminates potential for data inconsistency during sync * docs: document sync architecture and merge model - Detail the 3-way merge model logic - Describe the core synchronization architecture principles * fix(lint): explicitly ignore lock.Unlock return value errcheck linter flagged bare defer lock.Unlock() calls. Wrap in anonymous function with explicit _ assignment to acknowledge intentional ignore of unlock errors during cleanup. * fix(lint): add sync_merge.go to G304 exclusions The loadBaseState and saveBaseState functions use file paths derived from trusted internal sources (beadsDir parameter from config). Add to existing G304 exclusion list for safe JSONL file operations. * feat(sync): integrate sync-branch into pull-first flow When sync.branch is configured, doPullFirstSync now: - Calls PullFromSyncBranch before merge - Calls CommitToSyncBranch after export This ensures sync-branch mode uses the correct branch for pull/push operations. * test(sync): add E2E tests for sync-branch and external BEADS_DIR Adds comprehensive end-to-end tests: - TestSyncBranchE2E: verifies pull→merge→commit flow with remote changes - TestExternalBeadsDirE2E: verifies sync with separate beads repository - TestExternalBeadsDirDetection: edge cases for repo detection - TestCommitToExternalBeadsRepo: commit handling * refactor(sync): remove unused rollbackJSONLFromGit Function was defined but never called. Pull-first flow saves base state after successful push, making this safety net unnecessary. * test(sync): add export-only mode E2E test Add TestExportOnlySync to cover --no-pull flag which was the only untested sync mode. This completes full mode coverage: - Normal (pull-first): sync_test.go, sync_merge_test.go - Sync-branch: sync_modes_test.go:TestSyncBranchE2E (PR#918) - External BEADS_DIR: sync_external_test.go (PR#918) - From-main: sync_branch_priority_test.go - Local-only: sync_local_only_test.go - Export-only: sync_modes_test.go:TestExportOnlySync (this commit) Refs: #911 * docs(sync): add sync modes reference section Document all 6 sync modes with triggers, flows, and use cases. Include mode selection decision tree and test coverage matrix. Co-authored-by: Claude <noreply@anthropic.com> * test(sync): upgrade sync-branch E2E tests to bare repo - Replace mocked repository with real bare repo setup - Implement multi-machine simulation in sync tests - Refactor test logic to handle distributed states Coverage: sync-branch end-to-end scenarios * test(sync): add daemon sync-branch E2E tests - Implement E2E tests for daemon sync-branch flow - Add test cases for force-overwrite scenarios Coverage: daemon sync-branch workflow in cmd/bd * docs(sync): document sync-branch paths and E2E architecture - Describe sync-branch CLI and Daemon execution flow - Document the end-to-end test architecture * build(nix): update vendorHash for gofrs/flock dependency New dependency added for file-based sync locking changes the Go module checksum. --------- Co-authored-by: Claude <noreply@anthropic.com>
