Simon H	bd5480b9d0	fix: reduce if block nesting (#17662) ... * fix: reduce if block nesting This reduces if block nesting similar to how we did it in #15250 (which got lost during the `await` feature introduction): If the if expression doesn't contain an await expression or is not dependent on a blocker that is not already resolved, then we can avoid creating a separate `$.if()` statement. The one trade-off is that we'll do re-invocations for all the conditions leading up to the condition that matches. Therefore non-simple if expressions are wrapper in `$.derived` to avoid excessive recomputations. closes #17659 (~320 markers in prod mode possible now; less in dev because of our "wrap this component with devtime info" method) helps with #15200 * tweak * feedback	3 days ago

Rich Harris	bc44975869	fix: properly hydrate already-resolved async blocks (alternative) (#17641) ... This is basically #17611, minus #17640, plus #17639. We need to add the $.next() call after render tags as well as components; rather than duplicating the logic, we can use is_standalone to determine when this is necessary (since this is what prevents $.append(...) from being used).

Artyom Alekseevich	a75866f34d	fix: detect store in each block expression regardless of AST shape (#17636) ... The store invalidation detection in each blocks only checked for Identifier and MemberExpression AST node types. This caused bind: on iteration variables to silently fail when the expression used logical operators (e.g. `{#each $store.items ?? [] as item}`). Use expression metadata dependencies instead of AST type checking to find store_sub bindings, which correctly handles all expression shapes. Fixes #14625	1 week ago

Simon H	bc4dc1d10d	fix: avoid erroneous async derived expressions for blocks (#17604) ... fixes #17595 When an if/key/etc block has an expression that depends on an async blocker (e.g., is inside a component with top level `await`), the compiler incorrectly treats the expression as async - even when the expression itself contains no `await`. This causes the expression to be added to `$.async`'s `expressions` array, which wraps it in an `async_derived`. This is not only unnecessary but also buggy: it breaks the direct reactive connection between the source and its dependent effects, causing inconsistent effect executions. The fix is to only add expressions to `$.async`'s `expressions` array when they actually contain an `await`. When a branch is speculatively marked for destruction (condition temporarily falsy), its child effects are reset to `CLEAN` to prevent them running in a doomed branch (as of #17581). However, if the branch survives (condition becomes truthy again), those effects remain `CLEAN` and never run - the source was already marked dirty before the reset, so no new dirty marking occurs. The fix is to change `skipped_effects` from a `Set` to a `Map` that tracks which child effects were dirty/maybe_dirty before being reset. When a branch is unskipped (survives), restore their status and reschedule them. --------- Co-authored-by: Rich Harris <rich.harris@vercel.com>	1 week ago
