Summary

  • remember credential and local vector save choices for repeated saves of the current project
  • reset remembered choices when a new, loaded, or duplicated project changes the project generation
  • stop an in-progress save if the project changes while a prompt is open

Testing

  • npm run test:frontend
  • npm run build
  • pre-commit run --all-files
  • Playwright verification with us_cities.geojson and a credential-bearing XYZ layer in light and dark themes

Fixes #1934

Summary by CodeRabbit

  • New Features

    • Save preferences for credentials and local vector data are remembered within the current project.
    • Large embedded vector-data exports require renewed confirmation when needed.
  • Bug Fixes

    • Preferences reset when switching projects, preventing choices from applying to the wrong project.
    • Stale save prompts and responses are canceled when the project changes.
    • HTML exports are canceled if the active project changes during export.
    • Save and export results no longer update the newly active project after a switch.

📝 Walkthrough

Walkthrough

The save flow remembers credential and vector-data decisions for the active project generation. Project changes clear those decisions and cancel pending prompts or stale save and export operations.

Changes

Save-choice persistence

Layer / File(s) Summary
Project-scoped choice state
apps/geolibre-desktop/src/lib/project-save-choices.ts, tests/project-save-choices.test.ts
Defines credential and vector-data choices, scopes them to a project generation, merges new choices, and tests clearing, warning acknowledgment, and non-restoration across project changes.
Prompt generation tracking
apps/geolibre-desktop/src/hooks/useProjectFileActions.ts
Records the originating project generation on credential, vector-data, and file-name prompts. Removes stale prompts when the active project changes.
Save and export stale-operation guards
apps/geolibre-desktop/src/hooks/useProjectFileActions.ts
Reuses and persists remembered choices. Rejects stale answers and prevents replaced projects from receiving save paths, state, or export results.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 76102

The project save behavior changes are merge-ready after normal checks and review; no actionable merge-blocking risk remains.

Bugs

  • resolveLayersForSave captures state/state.projectGeneration before the await materializeEmbeddableVectorLayers(...) call, which can take real time. If the project is switched during that await, the remembered-choice lookup and saveChoicesRef.current write still operate on the stale generation, which can clobber already-remembered choices for the project that's actually loaded — forcing an unexpected extra prompt later. The new post-prompt generation guard doesn't cover this earlier gap. Not a data-leak (the stray prompt still self-cancels via the new useEffect), just a correctness gap in the "remember" bookkeeping. Confidence: medium. (inline comment)

Security

  • Once a "keep credentials" or "embed vector data" choice is remembered for a project generation, it's silently reapplied on every later save without re-prompting — including when the save now contains different/more credentials or substantially more embeddable data than when the choice was made. This appears to be the intended behavior per the linked issue (Desktop: Save prompts for credentials and local vector data reappear on every Cmd+S #1934), but is worth calling out since it means secrets can keep being written to disk, or large embeds keep growing past the documented LARGE_EMBED_WARNING_BYTES danger threshold (GeoLibre#1829), with no further confirmation until the project is reloaded. Confidence: low — plausibly an accepted tradeoff of the feature. (related inline comment on the embed-size case)

Performance

  • No issues found. materializeEmbeddableVectorLayers/estimateEmbedBytes costs are unchanged from before this PR; the remembered-choice path just adds a cheap generation comparison.

Quality

  • The new project-save-choices.ts module is a clean, dependency-free leaf module with its own focused test file — a good fit for this repo's coverage-floor conventions (avoids the "first test pulls in a huge transitive import graph" pitfall called out in CLAUDE.md). No issues found.
  • Logic in saveChoicesForProject/rememberProjectSaveChoices is straightforward and well-covered by tests/project-save-choices.test.ts.

CLAUDE.md

  • No violations found: no new user-facing strings requiring i18n, no MapLibre control styling, no touched files subject to the documented mirrored-constant rules, and the change stays within apps/geolibre-desktop.

Code review

Bugs

  • No logic errors found. The generation-guard checks in resolveLayersForSave/runSaveProject/handleExportHtml are placed correctly relative to their await points (every check follows the async gap it guards, and precedes any write to saveChoicesRef or the store), and the new useEffect correctly cancels stale prompts by comparing each prompt's captured projectGeneration to the live store value. Traced through all combinations of remembered/fresh choices for credentials and vector-data embedding, including the large-embed-warning re-confirmation logic in reusableVectorDataChoice, and didn't find a case where a stale generation's answer leaks into the new project or where a prompt gets double-resolved. High confidence.

Security

Performance

  • None found; the added checks are cheap object comparisons and closures.

Quality

  • Good extraction of the pure remember/forget logic into project-save-choices.ts, which is thoroughly unit-tested (4 tests covering scoping, generation reset, and the large-embed acknowledgment). This matches the project's documented preference (CLAUDE.md) for testing a small leaf module rather than the large hook file. Comments throughout useProjectFileActions.ts clearly explain the why for each new guard. No naming or readability issues.

CLAUDE.md

  • No violations found: no changes to CSP-allowlisted hosts, mirrored WASM constants, i18n strings (existing translation keys are reused), or the Whitebox menu catalog.

Both inline comments posted. Now finalizing the summary.

Code review

Bugs

  • reusableCredentialChoice reuses a remembered "keep" decision purely by comparing credential counts, not identity — swapping a credentialed layer for a different one (or removing one and adding another) while the count stays the same or drops re-uses "keep" without ever asking about the new credential, silently writing it to disk in plain text. Since the remembered choice persists across arbitrary edits within the same projectGeneration (not just identical repeat saves), this looks reachable in normal use. Medium confidence. (apps/geolibre-desktop/src/lib/project-save-choices.ts:84-91)

Quality

  • reusableVectorDataChoice's largeEmbedWarningAcknowledged is a one-shot boolean rather than tracking the acknowledged size, so once a user accepts the large-embed warning once, arbitrarily larger data on later saves is silently embedded with no further warning. Same shape of gap as the credential issue above, but lower severity and may be an intentional simplification per the adjacent code comment. Low-medium confidence. (apps/geolibre-desktop/src/lib/project-save-choices.ts:62-71)

Correctness of the generation-guarding mechanism (no issues found)

  • Traced all projectGeneration checks in useProjectFileActions.ts (resolveLayersForSave, runSaveProject, handleExportHtml) against every await point, and the stale-prompt-cancelling useEffect. Each async gap that could span a project switch is followed by a check before either prompting again or touching disk/state, including the case where resolveLayersForSave's own trailing buildEmbeddedLayers await isn't re-checked internally but is caught immediately by the caller with no intervening await. newProject/loadProject (the only two paths that bump projectGeneration in the store) are used consistently by every project-replacing action found (handleDuplicate, collaboration, share, startup, embed API, etc.), so the guard should cover all the scenarios the PR describes.

Security

  • No new injection, unsafe-input, or secret-leak issues found beyond the credential-reuse heuristic noted above.

Performance

  • Nothing notable; the added useAppStore.getState() calls and generation checks are O(1) and don't introduce extra renders or re-fetches.

CLAUDE.md

  • The new test (tests/project-save-choices.test.ts) targets the new leaf module project-save-choices.ts only, rather than importing the larger useProjectFileActions.ts hook — consistent with the repo's guidance to avoid coverage-floor regressions by testing leaf modules. No violations found.

- Track which credentials an explicit Keep covered, not how many. The
  redaction pass now returns a `path=hash` fingerprint per redacted path,
  and a remembered Keep is reused only when every credential this save
  would write is one the user was shown. Swapping one credentialed layer
  for another leaves the count unchanged, so the previous count check
  silently wrote a secret the user never approved.
- Re-warn when embedded vector data outgrows the acknowledged size.
  `largeEmbedWarningAcknowledged` became `acknowledgedEmbedBytes`, and the
  remembered Embed choice is reused only up to twice the size the user
  actually saw. Only a prompted answer records the size, so a silent reuse
  cannot ratchet the allowance in either direction.

Code review

Bugs

  • project-save-choices.ts:76-86reusableVectorDataChoice re-confirms "embed" when data grows past the acknowledged size, but a remembered "noembed" is reused forever regardless of size or which layers are involved. On the web build this means "Save without data" picked once for a small layer silently discards all local vector data on every subsequent save in that project session, including layers added later that the user would want embedded — with no re-prompt and no indication the choice is being remembered. Medium confidence; may be intentional but the failure mode looks real.

Security

  • packages/core/src/credentials.ts:88-103fingerprintValue is a non-cryptographic 32-bit hash used to decide whether a remembered "Keep credentials" answer can be silently reused. A collision (most plausible in the catch fallback, where different unserializable values both stringify to "[object Object]") would cause a missed re-confirmation rather than the "extra prompt" the adjacent comment claims. Low confidence/low severity — the secret would already be kept either way, this only affects whether the user is re-asked.

Performance

  • None found.

Quality

  • The Embed/Keep dialogs (ProjectFileDialogs.tsx, unchanged by this PR) never tell the user their choice will be remembered for the rest of the session, which compounds the "noembed" stickiness issue above — a user has no cue that a one-time click became a standing policy.
  • Otherwise the refactor of redactProjectCredentials/redactConfigurationValue to thread a single RedactionAccumulator is a clean, behavior-preserving simplification, and the generation-guard checks added throughout useProjectFileActions.ts are consistently placed after every await that could race with a project switch.

CLAUDE.md

  • No violations noted (no new UI strings, no touched allowlists/catalogs/mirrors relevant to this change).

- Reconfirm "Save without data" for layers the user never agreed to lose.
  A remembered noembed was reused unconditionally, so one click for a
  throwaway layer silently discarded every local vector layer added
  afterwards on the web build. The choice now records the layer ids it
  covered and re-asks when the save would drop one outside that set.
  Desktop discards nothing (it writes file references), so it stays silent.
- Fail closed when a credential cannot be fingerprinted. A collision costs
  a missed confirmation rather than an extra one, so the lossy
  String(value) fallback (every unserializable value collapsing onto
  "[object Object]") is gone: such values are reported through
  hasUnfingerprintableCredential and force a fresh Keep confirmation. The
  digest is also 64 bits now rather than 32, and the comment that had the
  collision impact backwards is corrected.

Code review

I reviewed useProjectFileActions.ts, the new project-save-choices.ts module, the credentials.ts fingerprinting changes, and both test files. The generation-based invalidation (cancelling stale prompts, bailing out of resolveLayersForSave/runSaveProject/handleExportHtml whenever projectGeneration drifts mid-flow) is applied consistently at every await boundary, and the remembered-choice reuse logic (reusableVectorDataChoice/reusableCredentialChoice) matches its accompanying tests exactly when hand-traced (growth-factor doubling, per-layer discard tracking, fingerprint-covered "keep" reuse, fail-closed on unfingerprintable/circular values). I did not find a functional bug.

Bugs: None found with meaningful confidence. Traced all the generation-mismatch race windows (embed prompt, credential prompt, save-name prompt, post-picker path assignment) and each is guarded correctly; the isSavingRef guard prevents saveProject/handleExportHtml from ever running concurrently, so saveChoicesRef can't be mutated by overlapping calls.

Security: None found. The new credential fingerprinting (fingerprintValue in packages/core/src/credentials.ts) only ever stores non-reversible hash digests in memory (never written to disk or the remembered-choices object as plaintext), and correctly fails closed (hasUnfingerprintableCredential) for values that can't be serialized (e.g. circular references), forcing re-confirmation rather than silently reusing a stale "keep".

Performance: No concerns; the redaction pass and fingerprinting are linear in project size, unchanged in complexity from before.

Quality: Very minor, low confidence — the comment on fingerprintValue (packages/core/src/credentials.ts) describes the two hash lanes as "two FNV-1a lanes," but the second lane's multiplier (0x85ebca6b) is a MurmurHash3 constant rather than the canonical FNV-1a prime. This has no functional impact (the hash is only ever used for equality comparison, not persisted or security-critical), so not flagging inline.

CLAUDE.md adherence: Good — the new project-save-choices.ts logic is tested via a dedicated leaf-module test file (tests/project-save-choices.test.ts) rather than through the larger hook, exactly the pattern the coverage-floor guidance calls for.

- Describe the fingerprint hash accurately. The second lane uses a
  MurmurHash3 mixing constant, not the FNV prime, so calling both lanes
  FNV-1a was wrong. Comment only, no behavior change.

Code review

I read through the full diff and the surrounding source (useProjectFileActions.ts, the new project-save-choices.ts module, and the credentials.ts fingerprinting changes), traced the generation-check/prompt-cancellation flow, and cross-checked the remembering/reconfirmation logic against its test suite.

Bugs

  • No high-confidence correctness bugs found. The projectGeneration staleness guards are applied consistently at every await boundary in resolveLayersForSave/runSaveProject/handleExportHtml, and the remembered-choice invalidation rules (embed growth factor, discarded-layer set, credential fingerprints) were traced through their edge cases (partial reuse, switching choices between saves, cancel paths) without finding a case where a stale or unintended choice gets silently applied. (Confidence: medium-high, based on manual trace rather than exhaustive testing.)
  • Low-confidence/cosmetic: the stale-prompt cancellation runs in useEffect rather than useLayoutEffect, so a modal could theoretically remain visible for one paint after the underlying project changes (see inline comment). Not a data-safety issue since the modal doesn't show project-identifying content and the promise still resolves to "cancel".

Security

  • Credential fingerprinting (fingerprintValue in credentials.ts) is a non-cryptographic 64-bit hash used only for in-memory equality comparison during a session; it's never persisted or transmitted, and a hash collision only causes a missed reconfirmation (not a spurious "safe to keep"), which is explicitly documented and an accepted tradeoff. No injection, leak, or unsafe-input issues found in the diff.

Performance

  • No material regressions. The credential-redaction pass now also hashes each redacted value, but existing isGeoJsonPayload short-circuiting (unchanged) still prevents descending into large embedded GeoJSON blobs, so the added hashing only touches small credential-sized values.

Quality

  • Minor duplication between the new stale-prompt-cancellation effect and the existing resolveCredentialStripPrompt/resolveEmbedVectorDataPrompt/cancelSaveNamePrompt handlers (see inline comment) — both implement the same "resolve + clear state" pattern independently.
  • The rest of the new code (project-save-choices.ts, the credential-fingerprint accumulator) is clearly commented, has matching unit tests for essentially every branch (growth-factor boundary, discarded-layer set changes, fingerprint mismatch/unfingerprintable fail-closed), and follows existing conventions in the file.

CLAUDE.md

  • No violations found: no new user-facing strings requiring i18n, no touches to any of the mirrored-constant invariants (Whitebox catalog, PMTiles zoom caps, etc.), and the new test file is correctly placed under tests/*.test.ts.

- Cancel stale save prompts in `useLayoutEffect` instead of `useEffect`, so a
  dialog belonging to a replaced project is gone in the same commit that
  swapped the project rather than lingering for one paint.
- Extract `settleCredentialStripPrompt` / `settleEmbedVectorDataPrompt` /
  `settleSaveNamePrompt` so the resolve-and-clear pattern lives in one place.
  The dialog handlers and the generation-change cancellation now share it and
  cannot drift apart; the helpers close over only their setters, so the effect
  still re-runs only when a prompt or the generation changes.

Code review

I reviewed the three substantive changes: the project-generation-aware prompt cancellation and remembered-choice wiring in useProjectFileActions.ts, the new pure-function module project-save-choices.ts, and the credential fingerprinting added to credentials.ts. I traced every projectGeneration guard, the saveChoicesRef read/write sequence across the async await points, and the reusableVectorDataChoice/reusableCredentialChoice reuse conditions against their test cases.

Bugs

  • None found. The generation checks after each await (in resolveLayersForSave, runSaveProject, handleExportHtml) correctly cover every point where the project could be replaced mid-flow, and the useLayoutEffect-based prompt cancellation is consistent with those checks. The single-flight isSavingRef guard (shared between save and export) rules out the overlapping-prompt races the new settle* helpers are designed to prevent.

Security

  • Low confidence: fingerprintValue in credentials.ts uses a non-cryptographic 64-bit hash (two FNV/Murmur-style lanes) to decide whether a "Keep credentials" choice can be silently reused. A hash collision would let a rotated/different secret be written to disk without re-prompting. The tradeoff is explicitly documented in the code comments and the practical risk is minimal (the "attacker" would need to control the user's own credential values), so this is more of a documented design tradeoff than a defect.

Performance

  • No concerns. Fingerprinting only runs over already-redacted, typically small credential fields during an explicit save/export action, not on a hot path.

Quality

  • Very low confidence: fingerprintValue relies on JSON.stringify key ordering for object/array credential values (e.g. headers), so two semantically-identical values with different key insertion order would fingerprint differently and force an unnecessary re-prompt. This fails in the safe direction (over-asking, not under-asking) and is unlikely to occur in practice since these objects are built consistently by the app, so it's not worth a code change.

CLAUDE.md

  • No violations. No new user-facing strings were added (existing i18n keys are reused), no new external hosts, no touched files subject to the WASM/plugin-version mirror rules, and no uv.lock/pyproject changes.

I did not find anything meeting the bar for an inline comment, so none were posted.
