Joe Schafer	d0dbe1a480	perf: skip quadratic blocker analysis when no top-level await (#18548 ) Skip function reference tracing in `calculate_blockers` when a component has no top-level `await`. Blockers only represent dependencies on top-level async statements. Without a top-level `await`, no binding can have a blocker, so tracing every top-level function cannot affect the generated output. In large components with many functions and transitive assignments, that unnecessary work can become quadratic.	5 days ago

Simon H	22e0adb75a	fix: rerun derived that had an abort controller on reconnection (#18551 ) Follow-up to #18400 - we need to mark a derived with an abort signal that is frozen as dirty so it is guaranteed to rerun when it reconnects/is re-requested. Else you could return a stale value, or worse, you returned a promise from the derived which you aborted, and it's now in the rejected state until you update one of its dependencies.	5 days ago

Simon H	edeef1f9f7	chore: add some failing tests (#18528 ) During my explorations I collected these new tests which are currently failing. Two of them work on the incremental-batches branch, all of them (adjusted for new behavior) pass on my uncommitted entangle batches branch, and all of them also pass on another uncommitted experimental branch of overlaying deriveds which will likely not land.	7 days ago

Simon H	af6f1d309b	chore: run every benchmark in its own process (#18542 ) While benchmarking it became apparent that when running the full `pnpm bench:compare` suite results could be wildly different compared to only comparing single benchmarks. The reason (most likely) is that the heap/GC/JIT state from one benchmark contaminates the others. Therefore this adjusts the runners such that each benchmark entry is run in its own forked process, not just each branch. This should give better, more stable results. Also a little fix to compare results by name; I made the mistake of adding a new benchmark to main which wasn't present on other branches yet, which made the results really confusing.	1 week ago

Ivan	5edd8b0602	fix: chain preprocessor sourcemaps with an empty sources[0] (#18518 ) ## Summary Fixes #18491 — the compiler discards an upstream plugin's sourcemap when it's generated without a `source` option (e.g. `new MagicString(code).generateMap()`), producing wrong devtools/stack-trace positions. ### Root cause `compile()` already supports composing an incoming sourcemap into its output via `options.sourcemap` (`merge_with_preprocessor_map` → `apply_preprocessor_sourcemap` → `combine_sourcemaps` in `packages/svelte/src/compiler/utils/mapped_code.js`). This is the same mechanism `preprocess()` uses internally, and it's the documented contract for tools that transform a `.svelte` file before compiling it (see `CompileOptions.sourcemap`'s doc comment). `combine_sourcemaps` composes maps by matching `sourcefile === filename` (the basename of the file being compiled). A sourcemap produced by `new MagicString(code).generateMap()` without a `source` option — which is exactly what the reporter's Vite plugin does — has `sources: ['']`. That empty string never equals `filename`, so `remapping()` treats the node as a leaf (the "original" file) instead of a branch to keep chaining through, and the whole incoming map is silently dropped. The result: every position that flows through that segment resolves to `{ source: null, line: null, column: null }`, which is what produces the wrong/missing devtools mapping described in the issue. Vite itself already has to handle this exact ambiguity: in `pluginContainer.ts`'s `_getCombinedSourcemap`, an empty `sources[0]` from a MagicString-based transform is patched to refer to the file being transformed before Vite uses it internally. This PR applies the same normalization on svelte's side, so the contract holds regardless of whether the caller happens to pass a `source` option to `generateMap()`. ### Fix In `apply_preprocessor_sourcemap`, normalize an incoming map's `sources: ['']` (or `[null]`/`[undefined]`) to `[filename]` before calling `combine_sourcemaps`, so the chain-matching step can actually find it.	2 weeks ago

Paolo Ricciuti	8fb7ceeba5	fix: don't treat declaration tags as parts inside each blocks (#18507 ) Closes #18506 Declaration tags in the scope of an each block were considered "parts" and transformed to use their value instead of the signal itself. We can safely check on the `kind` of the binding since a `kind` of `state`, `state_raw` or `derived` in the each scope needs to be a declaration tag (and it's a stable reference so we can use them directly)	2 weeks ago

Simon H	36ae0622a8	fix: always unset reactivity context after restoring it (#18453 ) When calling `save`, we restore the context after the promise resolves. But we do not unset it after the subsequent synchronous execution. That means that until `unset_context` runs in `async_derived` we will not have the correct (nulled) context. That causes problems if the `save` isn't the last promise contributing to the `async_derived`, because it means the context is not properly unset until the promise _after_ the `save` within the `async_derived` settles. This can cause all sorts of mixups, including a wrong mutation error. fixes #18441	4 weeks ago
