Andrey Antukh	b99157a246	🐛 Prevent thumbnail frame recursion overflow (#8763) ... Cache in-progress frame traversals before following parent frame links so thumbnail updates stop recursing forever on cyclic or transiently inconsistent shape graphs. Add a regression test that covers cyclic frame-id chains and keeps the expected frame/component extraction behavior intact. Signed-off-by: Andrey Antukh <niwi@niwi.nz>	2026-04-07 15:09:54 +02:00
Andrey Antukh	3ff1acfb6a	🐛 Fix vector index out of bounds in viewer zoom-to-fit/fill (#8834) ... Clamp the frame index to the valid range in zoom-to-fit and zoom-to-fill events before accessing the frames vector. When the URL query parameter :index exceeds the number of frames on the page (e.g. index=1 with a single frame), nth would throw "No item 1 in vector of length 1". Also adds unit tests covering the boundary condition.	2026-04-02 09:49:33 +02:00
Andrey Antukh	3767ee05bb	✨ Add retry mechanism for idenpotent get repo requests on frontend (#8792) ... * ♻️ Handle fetch-error gracefully with toast instead of full-page error Network-level failures (lost connectivity, DNS failure, etc.) on RPC calls were propagating as :internal/:fetch-error to the global error handler, which replaced the entire UI with a full-page error screen. Now the :internal handler distinguishes :fetch-error from other internal errors and shows a non-intrusive toast notification instead, allowing the user to continue working. * ✨ Add automatic retry with backoff for idempotent RPC requests Idempotent (GET) RPC requests are now automatically retried up to 3 times with exponential back-off (1s, 2s, 4s) when a transient error occurs. Retryable errors include: network-level failures (:fetch-error), 502 Bad Gateway, 503 Service Unavailable, and browser offline (status 0). Mutation (POST) requests are never retried to avoid unintended side-effects. Non-transient errors (4xx client errors, auth errors, validation errors) propagate immediately without retry. * ♻️ Make retry helpers public with configurable parameters Make retryable-error? and with-retry public functions, and replace private constants with a default-retry-config map. with-retry now accepts an optional config map (:max-retries, :base-delay-ms) enabling callers and tests to customize retry behavior. * ✨ Add tests for RPC retry mechanism Comprehensive tests for the retry helpers in app.main.repo: - retryable-error? predicate: covers all retryable types (fetch-error, bad-gateway, service-unavailable, offline) and non-retryable types (validation, authentication, authorization, plain errors) - with-retry observable wrapper: verifies immediate success, recovery after transient failures, max-retries exhaustion, no retry for non-retryable errors, fetch-error retry, custom config, and mixed error scenarios * ♻️ Introduce :network error type for fetch-level failures Replace the awkward {:type :internal :code :fetch-error} combination with a proper {:type :network} type in app.util.http/fetch. This makes the error taxonomy self-explanatory and removes the special-case branch in the :internal handler. Consequences: - http.cljs: emit {:type :network} instead of {:type :internal :code :fetch-error} - errors.cljs: add a dedicated ptk/handle-error :network method (toast); restore :internal handler to its original unconditional full-page error form - repo.cljs: simplify retryable-types and retryable-error? — :network replaces the former :internal special-case, no code check needed - repo_test.cljs: update tests to use {:type :network} * 📚 Add comment explaining the use of bit-shift-left	2026-03-30 12:20:02 +02:00
Andrey Antukh	b6524881e0	🐛 Fix crash in apply-text-modifier with nil selrect or modifier (#8762) ... * 🐛 Fix crash in apply-text-modifier with nil selrect or modifier Guard apply-text-modifier against nil text-modifier and nil selrect to prevent the 'invalid arguments (on pointer constructor)' error thrown by gpt/point when called with an invalid map. - In text-wrapper: only call apply-text-modifier when text-modifier is not nil (avoids unnecessary processing) - In apply-text-modifier: handle nil text-modifier by returning shape unchanged; guard selrect access before calling gpt/point * 📚 Add tests for apply-text-modifier in workspace texts Add exhaustive unit tests covering all paths of apply-text-modifier: - nil modifier returns shape unchanged (identity) - modifier with no recognised keys leaves shape unchanged - :width / :height modifiers resize shape correctly - nil :width / :height keys are skipped - both dimensions applied simultaneously - :position-data is set and nil-guarded - position-data coordinates translated by delta on resize - shape with nil selrect + nil modifier does not throw - position-data-only modifier on shape without selrect is safe - selrect origin preserved when no dimension changes - result always carries required shape keys * 🐛 Fix zero-dimension selrect crash in change-dimensions-modifiers When a text shape is decoded from the server via map->Rect (which bypasses make-rect's 0.01 minimum enforcement), its selrect can have width or height of exactly 0. change-dimensions-modifiers and change-size were dividing by these values, producing Infinity scale factors that propagated through the transform pipeline until calculate-selrect / center->rect returned nil, causing gpt/point to throw 'invalid arguments (on pointer constructor)'. Fix: before computing scale factors, guard sr-width / sr-height (and old-width / old-height in change-size) against zero/negative and non-finite values. When degenerate, fall back to the shape's own top-level :width/:height so the denominator and proportion-lock base remain consistent. Also simplify apply-text-modifier's delta calculation now that the transform pipeline is guaranteed to produce a valid selrect, and update the test suite to test the exact degenerate-selrect scenario that triggered the original crash. Signed-off-by: Andrey Antukh <niwi@niwi.nz> * ♻️ Simplify change-dimensions-modifiers internal logic - Remove the intermediate 'size' map ({:width sr-width :height sr-height}) that was built only to be assoc'd and immediately destructured back into width/height; compute both values directly instead. - Replace the double-negated condition 'if-not (and (not ignore-lock?) …)' with a clear positive 'locked?' binding, and flatten the three-branch if-not/if tree into two independent if expressions keyed on 'attr'. - Call safe-size-rect once and reuse its result for both the fallback sizes and the scale computation, eliminating a redundant call. - Access :transform and :transform-inverse via direct map lookup rather than destructuring in the function signature, consistent with how the rest of the let-block reads shape keys. - Clean up change-size to use the same destructuring style as the updated function ({sr-width :width sr-height :height}). - Fix typo in comment: 'havig' -> 'having'. * ✨ Add tests for change-size and change-dimensions-modifiers Cover the main behavioural contract of both functions: change-size: - Scales both axes to the requested target dimensions. - Sets the resize origin to the shape's top-left point. - Nil width/height each fall back to the current dimension (scale 1 on that axis); both nil produces an identity resize that is optimised away. - Propagates the shape's transform and transform-inverse matrices into the resulting GeometricOperation. change-dimensions-modifiers: - Changing :width without proportion-lock only scales the x-axis (y scale stays 1), and vice-versa for :height. - With proportion-lock enabled, changing :width adjusts height via the inverse proportion, and changing :height adjusts width via the proportion. - ignore-lock? true bypasses proportion-lock regardless of shape state. - Values below 0.01 are clamped to 0.01 before computing the scale. - End-to-end: applying the returned modifiers via gsh/transform-shape yields the expected selrect dimensions. * ✨ Harden safe-size-rect with additional fallbacks The previous implementation could still return an invalid rect in several edge cases. The new version tries four sources in order, accepting each only if it passes a dedicated safe-size-rect? predicate: 1. :selrect – used when width and height are finite, positive and within [-max-safe-int, max-safe-int]. 2. points->rect – computed from the shape corner points; subject to the same predicate. 3. Top-level shape fields (:x :y :width :height) – present on all rect, frame, image, and component shape types. 4. grc/empty-rect – a 0,0 0.01×0.01 unit rect used as last resort so callers always receive a usable, non-crashing value. The out-of-range check (> max-safe-int) is new: it rejects coordinates that pass d/num? (finite) but exceed the platform integer boundary defined in app.common.schema, which previously slipped through undetected. Tests cover all four fallback paths, including the NaN, zero-dimension, and max-safe-int overflow cases. * ⚡ Optimise safe-size-rect for ClojureScript performance - Replace (when (some? rect) ...) with (and ^boolean (some? rect) ...) to keep the entire predicate as a single boolean expression without introducing an implicit conditional branch. - Replace keyword access (:width rect) / (:height rect) with dm/get-prop calls, consistent with the hot-path style used throughout the rest of the namespace. - Add ^boolean type hints to every sub-expression of the and chain in safe-size-rect? (d/num?, pos?, <=) so the ClojureScript compiler emits raw JS boolean operations instead of boxing the results through cljs.core/truth_. - Replace (when (safe-size-rect? ...) value) in safe-size-rect with (and ^boolean (safe-size-rect? ...) value), avoiding an extra conditional and keeping the or fallback chain free of allocated intermediate objects. * ✨ Use safe-size-rect in apply-text-modifier delta-move computation safe-size-rect was already used inside change-dimensions-modifiers to guard the resize scale computation. However, apply-text-modifier in texts.cljs was still reading (:selrect shape) and (:selrect new-shape) directly to build the delta-move vector via gpt/point. gpt/point raises "invalid arguments (on pointer constructor)" when given a nil value or a map with non-finite :x/:y, which can happen when a shape's selrect is missing or degenerate (e.g. decoded from the server via map->Rect, bypassing make-rect's 0.01 floor). Changes: - Promote safe-size-rect from defn- to defn in app.common.types.modifiers so it can be reused by consumers outside the namespace. - Replace the two raw (:selrect …) accesses in the delta-move computation with (ctm/safe-size-rect …), which always returns a valid, finite rect through the established four-step fallback chain. - Add two frontend tests covering the delta-move path with a fully degenerate (zero-dimension) selrect, ensuring neither a bare position-data modifier nor a combined width+position-data modifier throws. * ♻️ Ensure all test shapes are proper Shape records in modifiers-test All shapes in safe-size-rect-fallbacks tests now start from a proper Shape record built by cts/setup-shape (via make-shape) instead of plain hash-maps. Each test that mutates geometry fields (selrect, points, width, height) does so via assoc on the already-initialised record, which preserves the correct type while isolating the field under test. A (cts/shape? shape) assertion is added to each fallback test to make the type guarantee explicit and guard against regressions. The unused shape-with-selrect helper (which built a bare map) is removed. * 🔥 Remove dead code and tighten visibility in app.common.types.modifiers Dead functions removed (zero callers across the entire codebase): - modifiers->transform-old: superseded by modifiers->transform; only ever appeared in a commented-out dev/bench.cljs entry. - change-recursive-property: no callers anywhere. - move-parent-modifiers, resize-parent-modifiers: convenience wrappers for the parent-geometry builder functions; never called. - remove-children-modifiers, add-children-modifiers, scale-content-modifiers: single-op convenience builders; never called. - select-structure: projection helper; only referenced by select-child-geometry-modifiers which is itself dead. - select-child-geometry-modifiers: no callers anywhere. Functions narrowed from defn to defn- (used only within this namespace): - valid-vector?: assertion helper called only by move/resize builders. - increase-order: called only by add-modifiers. - transform-move!, transform-resize!, transform-rotate!, transform!: steps of the modifiers->transform pipeline. - modifiers->transform1: immediate helper for modifiers->transform; the doc-string describing it as 'multiplatform' was also removed since it is an implementation detail. - transform-text-node, transform-paragraph-node: leaf helpers for scale-text-content. - update-text-content, scale-text-content, apply-scale-content: internal scale-content pipeline; all called only by apply-modifier. - remove-children-set: called only by apply-modifier. - select-structure: demoted to defn- rather than deleted because it is still called by select-child-structre-modifiers, which has external callers. * ✨ Add more tests for modifiers --------- Signed-off-by: Andrey Antukh <niwi@niwi.nz>	2026-03-30 11:04:54 +02:00
