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.	2 months 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.	2 months 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.	2 months 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 months ago

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 months 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	3 months ago

Yuichiro Yamashita	c4daa490bb	fix: include wrapping parentheses in `{@const}` declarator end (#18436) ... `{@const x = (a)}` (and any `{@const}` whose initializer is wrapped in parentheses, e.g. `(a = b)`, `({ ... })`) produced a `VariableDeclarator` whose `end` fell before the closing `)`. `read_expression` strips the wrapping parens from the returned node but advances the parser past them, so `init.end` excludes the `)` while the parser position does not. Use the parser position for the declarator `end` instead. Fixes source slices / tooling that rely on the node range (the range previously yielded invalid, unbalanced source). <img width="2064" height="1746" alt="image" src="https://github.com/user-attachments/assets/64153ee5-d543-442d-8018-d3668acfd7a7" /> ### Before submitting the PR, please make sure you do the following - [x] It's really useful if your PR references an issue where it is discussed ahead of time.

Nic Polumeyv	0510174bc0	fix: make `SvelteURLSearchParams` notifications accurate (#18425) ... `SvelteURLSearchParams` has two notification bugs that surface through `SvelteURL`. The first is over-notification. Setting `url.href` always rebuilds the params and bumps their version signal, even when the search string didn't change at all. Effects that read `size` (or any params method) re-run on every unrelated `href` write, which is #17218, where it caused infinite effect loops in a router. The fix is a guard in the internal replace path that bails out when the incoming params serialize identically to the current ones. The second is under-notification, and it's sneakier. Every read method tracks the version signal, `get`, `getAll`, `has`, `keys`, `values`, `entries`, `toString`, `size`, the iterator... except `forEach`, which was never overridden. The inherited platform method reads the internal list directly and subscribes to nothing, so a template that renders params via `forEach` never updates: ```js $effect(() => { url.searchParams.forEach((value, key) => entries.push(`${key}=${value}`)); // never re-runs }); ``` We found this one in the wild while making `page.url` a `SvelteURL` in sveltejs/kit#16031. Kit's own test suite renders query params with `forEach`, and the coarse object-identity signal that previously masked the gap went away, leaving stale UI after client-side navigations. The fix is the same one-line tracking pattern every other read method already uses. Fixes #17218 --- - [x] It's really useful if your PR references an issue where it is discussed ahead of time.

dependabot[bot]	8ea3ee8c62	chore(deps-dev): bump esbuild from 0.25.11 to 0.28.1 (#18427) ... Bumps [esbuild](https://github.com/evanw/esbuild) from 0.25.11 to 0.28.1. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/evanw/esbuild/releases">esbuild's releases</a>.</em></p> <blockquote> <h2>v0.28.1</h2> <ul> <li> <p>Disallow <code>\</code> in local development server HTTP requests (<a href="https://github.com/evanw/esbuild/security/advisories/GHSA-g7r4-m6w7-qqqr">GHSA-g7r4-m6w7-qqqr</a>)</p> <p>This release fixes a security issue where HTTP requests to esbuild's local development server could traverse outside of the serve directory on Windows using a <code>\</code> backslash character. It happened due to the use of Go's <code>path.Clean()</code> function, which only handles Unix-style <code>/</code> characters. HTTP requests with paths containing <code>\</code> are no longer allowed.</p> <p>Thanks to <a href="https://github.com/dellalibera"><code>@​dellalibera</code></a> for reporting this issue.</p> </li> <li> <p>Add integrity checks to the Deno API (<a href="https://github.com/evanw/esbuild/security/advisories/GHSA-gv7w-rqvm-qjhr">GHSA-gv7w-rqvm-qjhr</a>)</p> <p>The previous release of esbuild added integrity checks to esbuild's npm install script. This release also adds integrity checks to esbuild's Deno install script. Now esbuild's Deno API will also fail with an error if the downloaded esbuild binary contains something other than the expected content.</p> <p>Note that esbuild's Deno API installs from <code>registry.npmjs.org</code> by default, but allows the <code>NPM_CONFIG_REGISTRY</code> environment variable to override this with a custom package registry. This change means that the esbuild executable served by <code>NPM_CONFIG_REGISTRY</code> must now match the expected content.</p> <p>Thanks to <a href="https://github.com/sondt99"><code>@​sondt99</code></a> for reporting this issue.</p> </li> <li> <p>Avoid inlining <code>using</code> and <code>await using</code> declarations (<a href="https://redirect.github.com/evanw/esbuild/issues/4482">#4482</a>)</p> <p>Previously esbuild's minifier sometimes incorrectly inlined <code>using</code> and <code>await using</code> declarations into subsequent uses of that declaration, which then fails to dispose of the resource correctly. This bug happened because inlining was done for <code>let</code> and <code>const</code> declarations by avoiding doing it for <code>var</code> declarations, which no longer worked when more declaration types were added. Here's an example:</p> <pre lang="js"><code>// Original code { using x = new Resource() x.activate() } <p>// Old output (with --minify)<br /> new Resource().activate();</p> <p>// New output (with --minify)<br /> {using e=new Resource;e.activate()}<br /> </code></pre></p> </li> <li> <p>Fix module evaluation when an error is thrown (<a href="https://redirect.github.com/evanw/esbuild/issues/4461">#4461</a>, <a href="https://redirect.github.com/evanw/esbuild/pull/4467">#4467</a>)</p> <p>If an error is thrown during module evaluation, esbuild previously didn't preserve the state of the module for subsequent module references. This was observable if <code>import()</code> or <code>require()</code> is used to import a module multiple times. The thrown error is supposed to be thrown by every call to <code>import()</code> or <code>require()</code>, not just the first. With this release, esbuild will now throw the same error every time you call <code>import()</code> or <code>require()</code> on a module that throws during its evaluation.</p> </li> <li> <p>Fix some edge cases around the <code>new</code> operator (<a href="https://redirect.github.com/evanw/esbuild/issues/4477">#4477</a>)</p> <p>Previously esbuild incorrectly printed certain edge cases involving complex expressions inside the target of a <code>new</code> expression (specifically an optional chain and/or a tagged template literal). The generated code for the <code>new</code> target was not correctly wrapped with parentheses, and either contained a syntax error or had different semantics. These edge cases have been fixed so that they now correctly wrap the <code>new</code> target in parentheses. Here is an example of some affected code:</p> <pre lang="js"><code>// Original code new (foo()`bar`)() new (foo()?.bar)() <p>// Old output<br /> new foo()<code>bar</code>();<br /> new (foo())?.bar();</p> <p></code></pre></p> </li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...

sijie-Z	71a6515bd6	fix: check boundary exists before calling error handler in async derived (#18384) ... fixes #18383 I traced the issue to `packages/svelte/src/internal/client/error-handling.js`, specifically the `invoke_error_boundary` function. The problem is at line 56 where `effect.b.error(error)` is called without checking if `effect.b` exists. What happens is: when an async `$derived` rejects inside a `<svelte:boundary>`, the error is handled correctly the first time. But if the boundary is destroyed before the rejection fully settles (e.g. component unmounts), a subsequent settle tries to call `effect.b.error()` on a destroyed boundary where `effect.b` is `null`, causing a `TypeError`. The fix adds a null check for `effect.b` before calling `error()`. If the boundary has been destroyed, we skip it and continue bubbling up to the parent boundary. This way the error still gets handled properly instead of crashing. This could also be tested by creating a component with an async `$derived` that rejects after the component unmounts, but I wanted to get the fix up first for review. --------- Co-authored-by: Rich Harris <rich.harris@vercel.com>	3 months ago
