* ♻️ 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}

* 🐛 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.

* ♻️ 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.
