fix: preserve interrupted DynamoDB loads - #311
Conversation
- retain the paused load owner through nested context overlays - cover settings and saved-view returns without duplicate resumes
WalkthroughThe change adds cycle-safe overlay traversal, preserves return destinations across nested overlays, removes duplicate CloudFormation traversal, clears stale loading state after region changes, and adds regression coverage for stacked overlays and interrupted DynamoDB loads. ChangesContext overlay flow
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to A regression test still depends on direct AWS client setup rather than a mock, which can make validation environment-sensitive. The PR is mergeable with owner awareness and follow-up to isolate the test from external AWS configuration. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

The changes correctly implement the preservation of interrupted DynamoDB loads when navigating through nested overlays (Settings/Views → Context Picker). The refactored condition logic properly handles both settings and views screens, and the new test coverage validates the expected behavior comprehensively. No blocking issues found.

[P2] Preserve the paused load through stacked overlays —
internal/app/app.go:693returnsToContextPickeronly recognizes an overlay whose immediateprevScreenis the context picker. Settings and Saved Views can open each other through their global shortcuts, soDynamoDB loading → C → Settings → Saved Views → Cleavesviews.prevScreen == screenSettings; this branch then overwritesctxPrevScreenwithscreenViewListand clearsctxPrevWasLoading. Escaping the reopened picker returns to Saved Views instead of restarting DynamoDB, and further Esc presses cycle through Saved Views → Settings → Context Picker → Saved Views. Preserve the existing interrupted-load owner across any non-committing overlay chain (for example, whilectxPrevWasLoadingis already true), and add regressions for bothS → V → CandV → S → C.

[P2] Clear the interrupted load after a committed region switch —
internal/app/app.go:696The new
!m.ctxPrevWasLoadingguard preserves the old DynamoDB return target whenever the flag is set, even after navigation has left the context-picker overlay chain. With a multi-region context, reproduce this as: start a DynamoDB load →C→S(orV) →R→ choose a different region →C→ Esc.regionSwitchedMsgreturns to the service list without clearingctxPrevWasLoading, so the laterCno longer records the service list as its return screen; Esc then callsresumeLoadingand unexpectedly opens DynamoDB in the newly selected region. Clear the interrupted-load flag when the region switch is committed (or restrict preservation to overlay chains that still lead back to the context picker), and add this sequence as a regression test.

[P2] Preserve the original return through stacked non-loading overlays —
internal/app/app.go:696returnsToContextPickeronly follows the immediate overlay parent, while the newctxPrevWasLoadingguard only protects stacked paths that began by interrupting DynamoDB. From the service list,C → S → V → CleavesctxPrevWasLoading == falseandviews.prevScreen == screenSettings, so this branch overwritesctxPrevScreenwithscreenViewList. Esc then cycles through Context Picker → Saved Views → Settings → Context Picker instead of returning to the service list;C → V → S → Chas the same problem. Preserve the originalctxPrevScreenwhenever the active Settings/Saved Views chain ultimately originated at the context picker (independent of the DynamoDB flag), and add non-loading regressions for both stacked orderings that verify Esc reaches the original screen without cycling.

[P2] Preserve the context return through repeated overlay alternation —
internal/app/app.go:721The new traversal handles one Settings/Saved Views nesting, but a third alternating overlay overwrites the only parent slot and creates a cycle before this check runs. From the service list,
C → S → V → S → CleavessettingsPrevScreen == screenViewListandviews.prevScreen == screenSettings;overlayChainMatchestherefore detects theSettings ↔ Saved Viewscycle and returns false, so this branch replacesctxPrevScreenwith Settings. Canceling the picker then loops through Settings and Saved Views instead of returning to the service list. The symmetricC → V → S → V → Cpath has the same regression. Preserve a stable root return target (or avoid replacing a parent when doing so creates this cycle), and add regressions for both repeated alternations.

No actionable findings. The cycle-safe overlay traversal resolves the prior stacked Settings/Saved Views return failures, and committed navigation paths clear the interrupted-load marker.
Validation passed: focused regressions, make test, make build, and git diff --check.

[P2] Keep the command-palette parent stable too —
internal/app/screen_palette.go:90openPalettestill unconditionally overwritespalette.prevScreen, so the repeated-overlay cycle remains when the palette participates. From the service list,C → P → S → P → Cmakespalette.prevScreen == screenSettingswhilesettingsPrevScreen == screenCommandPalette;overlayChainMatchesdetects that cycle and returns false, and the finalCrecords the palette asctxPrevScreen. Esc then cycles Palette ↔ Settings instead of returning to the service list. Apply the same stable-parent guard used for Settings and Saved Views to the palette, and add regressions for Palette with both Settings and Saved Views.

The code changes correctly extract duplicate overlay chain matching logic into a shared utility function. The refactoring improves maintainability by removing code duplication between CloudFormation and context picker flows. All tests pass and the implementation properly handles overlay traversal with cycle detection.

[P2] Traverse the region picker when preserving overlay parents —

In a multi-region context,C → S → R → Cmakes the secondCtreat the Region picker as a new root and overwritectxPrevScreen; successive Esc presses then loop Context Picker → Region → Settings → Context Picker instead of returning to the service list. Reopening Settings or Saved Views through Region can similarly form a mutual cycle because theRhandler at line 741 always replacesregionPrevScreen. FollowregionPrevScreenin this traversal and preserve its stable parent using the same guard as the other overlays, with a regression covering the no-switch/cancel path.

No actionable findings. The shared cycle-safe traversal preserves stable overlay parents across Settings, Saved Views, Command Palette, and Region Picker, while committed region switches clear the interrupted DynamoDB resume state.

The changes correctly preserve interrupted DynamoDB loads when Settings or Saved Views reopen the context picker, preventing overlay return cycles. The implementation properly reuses the overlayChainMatches utility function across CloudFormation, command palette, and saved views screens. The ctxPrevWasLoading flag is appropriately reset after region switches. The comprehensive test coverage validates all the edge cases for overlay interactions and context switches.
