Improve branch name sanitization and refresh UI state

Summary

  • Tightens GitBranchNameSanitizer.sanitize to enforce Git branch naming rules.
  • Improves background refresh/UI update behavior across SyncState and file status views to reduce stale or unnecessary re-renders.

Changes

Branch name sanitization (macgit/Models/GitBranchNameSanitizer.swift)

  • Replaces forbidden characters (~ ^ : ? * [ \, control characters) with -, and @{ with -.
  • Collapses .. sequences to -.
  • Strips leading - / / (branch names are stricter than refs) and re-runs sanitization if a leading dash remains.
  • Splits on / and per component: strips leading ., trailing .lock, and trailing ., dropping empty components.
  • Appends -branch when the result is @ or HEAD.

Refresh / state (macgit/Services/SyncState.swift)

  • refreshedLocalStatuses is now @Published private(set), and its entry is only updated when the status actually changes.
  • Adds backgroundPollingInterval (5s), shortens autoFetchInterval from 60s to 15s.
  • Background loop now tracks a ContinuousClock and only performs a local refresh once backgroundRefreshInterval (10s) has elapsed, sleeping for the shorter polling interval in between.

File status views

  • FileStatusNativeList.swift: splits scaleChanged and structureChanged handling. On structure change it computes an id difference, performs batched row remove/insert inside an NSAnimationContext (duration 0), then restores the viewport. Row-change detection now matches rows by file.id via a previous-rows dictionary instead of comparing by index.
  • FileStatusView.swift: replaces the .repositoryLocalStateDidRefresh notification subscription with a syncState.$refreshedLocalStatuses publisher keyed by repositoryURL; adds a statusLoadGeneration counter to guard async status loads; loads LFS paths and recent commits into locals before applying.

Sidebar

  • SidebarView+Loading.swift and SidebarView.swift were modified (diff content for these files was not included in the truncated patch).

Notes / uncertainty

  • The supplied patch is truncated, so the body of SidebarView+Loading.swift, SidebarView.swift, and the remainder of loadStatus() in FileStatusView.swift are not visible; behavior changes there are not described.
  • No test changes are present in the supplied diff, so automated verification is not evidenced.

Summary by CodeRabbit

  • New Features
    • Pull request details open in a separate resizable window, with controls to open or merge the request when available.
    • Pull request conversations include a refresh control and comment composer.
  • Improvements
    • Pull request changes show additions and deletions in green and red, and folder icons appear blue.
    • Automatic sync checks run more frequently, and matching branch updates refresh in the sidebar.
    • Cached pull request details can appear while fresh data loads; existing lists remain visible during refresh errors.
  • Bug Fixes
    • Branch names are cleaned up to avoid invalid Git characters and formatting.
    • File status updates display more reliably when rows move or text size changes, and stale loads are less likely to overwrite newer status.

Sanitize forbidden characters, consecutive dots, and .lock suffixes in branch names.
Use structure-aware row updates in file status list to avoid full reloads.
Publish refreshed local statuses and poll background sync more frequently.

📝 Walkthrough

The changes expand Git branch-name sanitization, adjust repository refresh and file-status updates, and change pull-request caching and detail presentation. Pull-request details now open in managed windows.

Changes: Branch-name sanitization

Layer / File(s) Summary
Normalize Git branch names
macgit/Models/GitBranchNameSanitizer.swift, macgitTests/GitFlowLitePhase1Tests.swift
sanitize replaces disallowed characters, normalizes slash-separated components, and adds a suffix when the result is @ or HEAD. Tests cover trailing periods and repeated .lock suffixes.

Repository and file-status refresh

Layer / File(s) Summary
Publish and schedule local status refreshes
macgit/Services/SyncState.swift
Local status refreshes publish changed values. Polling uses a 5-second interval, local refreshes are gated to 10 seconds, and automatic fetches use a 15-second interval.
Apply status loads and snapshots
macgit/Views/FileStatus/FileStatusView.swift
Status loads reject superseded results. Accepted loads update changed files, and background snapshots update status, refresh affected line counts, restore selection, and request a full refresh.
Update native file-status rows
macgit/Views/FileStatus/FileStatusNativeList.swift
Row insertions and removals use file IDs. Changed rows are matched by file ID, and updates restore the viewport.
Reload sidebar branches and sync status
macgit/Views/MainWindow/SidebarView+Loading.swift, macgit/Views/MainWindow/SidebarView.swift
Branch reloads reset status tracking. Status dictionaries are assigned only when changed. Matching refresh notifications force-reload branches; remote reloads remain limited to user-initiated notifications.

Pull-request details and cache

Layer / File(s) Summary
Load and retain pull-request cache data
macgit/Services/PullRequestDiskCache.swift, macgit/App/PullRequestController.swift
Cache entries store fetch and expiry timestamps. The controller displays cached list and detail data, retains loaded lists after fetch errors, and refreshes expired detail entries.
Manage pull-request detail windows
macgit/App/PullRequestDetailWindowController.swift, macgit/Views/PullRequests/PullRequestListView.swift
Selecting a pull request opens or activates a managed detail window. Its content displays loading, detail, or error states, and closing clears the selection and detail state.
Update detail actions and overview layout
macgit/Views/PullRequests/PullRequestDetailHeader.swift, macgit/Views/PullRequests/PullRequestListView.swift
The detail header provides open and merge actions. The overview uses a persistent resizable split for conversation and metadata.
Update pull-request change summaries
macgit/Views/PullRequests/PullRequestChangesView.swift
Folder icons use blue styling, and file additions and deletions appear as separate green and red counts.

Reopening a pull-request list within its cache lifetime can make an unnecessary network request and show an avoidable error. This is a bounded issue suitable for a follow-up.

Cache entry expiry now drives detail refresh decisions.
Retain loaded list state on fetch errors.
Preserve fetched entries past expiration and surface refresh errors without clearing the loaded list.

Honor the list cache expiry before fetching.

When diskCache.entry returns a fresh page and forceRefresh is false, apply the cached page and return. Continue fetching for expired entries and forced refreshes. The current flow always calls service.listPullRequests, so opening the list within its 120-second TTL makes a redundant provider request and can show an error despite fresh cached data.
