Simon Holthausen	99858221ec	fix: reset context after waiting on blockers of `@const` expressions ... Regression from #18039 - we need to have each await expression (and waiting on blockers is one) in its own entry of `(renderer.)run`. Else context is not restored correctly and if the synchronous expression afterwards requires it stuff breaks. Fixes #18098	2 days ago
github-actions[bot]	4a50e8ea3b	Version Packages (#18085) ... This PR was opened by the [Changesets release](https://github.com/changesets/action) GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated. # Releases ## svelte@5.55.3 ### Patch Changes - fix: ensure proper HMR updates for dynamic components ([#18079](https://github.com/sveltejs/svelte/pull/18079)) - fix: correctly calculate `@const` blockers ([#18039](https://github.com/sveltejs/svelte/pull/18039)) - fix: freeze deriveds once their containing effects are destroyed ([#17921](https://github.com/sveltejs/svelte/pull/17921)) - fix: defer error boundary rendering in forks ([#18076](https://github.com/sveltejs/svelte/pull/18076)) - fix: avoid false positives for reactivity loss warning ([#18088](https://github.com/sveltejs/svelte/pull/18088)) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>	3 days ago
Simon H	15588f5fbf	fix: avoid false positives for reactivity loss warning (#18088) ... Avoids two categories of false positives for reactivity loss warning: 1. if you have synchronously read signals already as part of invoking the async_derived function, then it shouldn't warn when these signals are read after an await if we know they haven't changed (we check the write version for that) 2. `track_reactivity_loss` kept the `reactivity_loss_tracker` around indefinitely, both when invoking the async operation as well as when it's finished. The former is buggy because while the async operation happens unrelated reads as part of other reactivity work can happen, the latter is buggy because if it's the last in a chain of awaits it's kept around until the next async work starts.

Rich Harris	0e9e76f292	fix: freeze deriveds once their containing effects are destroyed (#17921) ... Per https://github.com/sveltejs/svelte/pull/17862#issuecomment-4049752548, this freezes the value of a derived if it was created inside a parent effect that is now destroyed. This prevents the sort of bug where a derived reads `foo.bar` even though `foo` is now `undefined`. If the derived is dirty, a warning will be printed. This PR also gets rid of some weirdness around `derived.parent` — it can only ever be an `Effect | null`, and there's no need for `get_derived_parent_effect`. Blocked on https://github.com/sveltejs/kit/pull/15533 and a follow-up that switches remote functions to use `$effect.root` (since this effectively undoes #17171), hence draft. ### Before submitting the PR, please make sure you do the following - [x] It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs - [x] Prefix your PR title with `feat:`, `fix:`, `chore:`, or `docs:`. - [x] This message body should clearly illustrate what problems it solves. - [x] Ideally, include a test that fails without this PR but passes with it. - [x] If this PR changes code within `packages/svelte/src`, add a changeset (`npx changeset`). ### Tests and linting - [x] Run the tests with `pnpm test` and lint the project with `pnpm lint` --------- Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com> Co-authored-by: Simon H <5968653+dummdidumm@users.noreply.github.com>	4 days ago
Simon H	3937ec03bd	fix: correctly calculate `@const` blockers (#18039) ... Move the calculation of blockers into the analysis phase and then only push the right thunks in the transform phase - similar to how we already do it with top level `$.run` Fixes #18024 The solution is a tiny bit brittle (not much more than the top level one we already have) and I tried to make it a bit more robust but ended up in a rabbit hole in #18032 - we can revisit that solution once all the old stuff is gone. Until then this is the most pragmatic/non-invasive change. --------- Co-authored-by: Rich Harris <rich.harris@vercel.com>	4 days ago
Simon H	7be1a0247f	fix: ensure proper HMR updates for dynamic components (#18079) ... The BranchManager in `branches.js` does create a temporary anchor when creating a new branch offscreen, and deletes it once the branch is committed. Normally this is fine, but the combination of HMR and dynamic components leads to a bug: Since `svelte-component.js` passes the temporary anchor along to the component it generates, which is the HMR wrapper, this wrapper will have an obsolete, disconnected anchor on updates, leading to the content disappearing. The fix is to add a dev-only symbol which we set on the original (then obsolete) anchor to tell about the updated anchor that should be used for HMR updates. Fixes https://github.com/sveltejs/kit/issues/14699 Fixes #17211	5 days ago
Simon H	a4ce776070	fix: defer error boundary rendering in forks (#18076) ... RIght now, when an async error occurs inside a fork, the error UI will show immediately. This change defers the removal of the current content etc until the fork is committed. The BranchManager logic cannot be reused here since this is not about pending work, and we cannot wait for other pending work to complete if the fork commits. Instead, batches now have a "on fork commit" callback set which the boundary pushes to. The boundary's effects are skipped in the fork until it's committing, at which point we "resume" the error logic (calling onerror, transforming it, etc) Fixes #18060	5 days ago

Rich Harris	8966601dcd	fix: handle parens in template expressions more robustly (#18075) ... While looking into #17954 I realised that a) our code for handling parentheses in expressions is unnecessarily convoluted and b) it doesn't handle the case where you have an opening parent outside the first comment — this fails to parse: ```svelte {(/**/ 42)} ``` This fixes it and simplifies the code a good bit. ### 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.

Simon H	0395ef0df7	fix: unskip branches of earlier batches after commit (#18048) ... Fixes #17571 where the situation is the following: A derived creates a new query. That query initializes loading with true. This means the if block is marked for destruction (therefore effects inside branch are skipped), but it's not doing that yet because the query promise is pending. Then query resolves and loading is set back to false right before resolving, but it's not the same tick so `loading=false` is a separate thing. Because that later batch doesn't see any overlap with an earlier batch (the earlier batch did set loading to true but not via set but indirectly via recreating the query) it doesn't wait on it and flushes right away. Now the if block is marked as visible again but the earlier batch doesn't know that if noone unskips its branch. If we don't do that the render effect that is now dirty as part of that batch will not run.	7 days ago

Simon H	d86cb5cc32	fix: skip rebase logic in non-async mode (#18040) ... Fixes part of #17940 (the hydration->error thing still needs a repro). Essentially in sync mode render effects are executed during traversing the effect tree, and when flushSync is called during that it can cause the timing of things getting out of sync such that you end up wanting to rebase another branch, which is never needed in sync mode. So we just skip that logic in sync mode. Another way would be to adjust flushSync such that it does appends itself to the end of the current flushing cycle if it notices processing is already ongoing. This will not work when you pass a callback function to `flushSync` though - another indicator that we should probably remove that callback argument. --------- Co-authored-by: Rich Harris <rich.harris@vercel.com> Co-authored-by: Rich Harris <hello@rich-harris.dev>	7 days ago
Simon H	adba758067	fix: don't reset status of uninitialized deriveds (#18054) ... If a new branch is created (e.g. if block becomes truthy) inside a fork and a derived is read inside the new branch for the first time, it will get reactions but its true value will stay uninitialized due to the fork. If the fork then commits, it will NOT change its value because it will not reexecute: there is no effect running after commit telling it to do that, because it was only read inside new effects which already ran while still inside the fork. Now, when that branch is removed (e.g. if block becomes falsy), the derived loses its reactions again and becomes disconnected, at which point the status is reset. So we end up with a maybe_dirty or clean derived and an uninitialized value, causing breakage if it's called again afterwards. The fix is to not reset the status in this case.

We will likely want to put other stuff in `AGENTS.md` in future but I figured we could start with something immediately useful.

dagecko	e0f925116c	fix: pin 9 actions to commit SHA (#18025) ... Re-submission of #18017. Had a problem with my fork and had to delete it, which closed the original PR. Apologies for the noise. ## Summary This PR pins all GitHub Actions to immutable commit SHAs instead of mutable version tags. - Pin 9 unpinned actions to full 40-character SHAs - Add version comments for readability ## Changes by file | File | Changes | |------|---------| | autofix.yml | Pinned actions to SHA | | ci.yml | Pinned actions to SHA | | pkg.pr.new.yml | Pinned actions to SHA | | release.yml | Pinned actions to SHA | ## A note on internal action pinning This PR pins all actions including org-owned ones. Best practice is to pin everything — the tj-actions/changed-files attack was an internally maintained action that was compromised, and every repo referencing it by tag silently executed attacker code. That said, it's your codebase. If you'd prefer to leave org-owned actions unpinned, let us know and we'll adjust the PR. ## How to verify Review the diff — each change is mechanical and preserves workflow behavior: - **SHA pinning**: `action@v3` becomes `action@abc123 # v3` — original version preserved as comment - No workflow logic, triggers, or permissions are modified I wrote a scanner called Runner Guard and open sourced it [here](https://github.com/Vigilant-LLC/runner-guard).

Rohit Nair P	4879f9da99	fix: improve duplicate module import error message (#18016) ... ## Description **While investigating the compiler analysis phase for errors or missing lines, I located an explicit `TODO fix the message here` comment in the source code (`packages/svelte/src/compiler/phases/2-analyze/visitors/shared/utils.js`).** ### Triggering Code ```svelte <script module> import { foo } from './somewhere.js'; </script> <script> let foo = 'conflict'; // Triggers the duplicate module import error </script> ``` ## The Bug When a component author creates a local `let` declaration in the instance `<script>` block that shadows a variable imported in the `<script module>` block, the compiler emits a `declaration_duplicate_module_import` error. However, the error message text was misleading. It stated: ```diff - Cannot declare a variable with the same name as an import inside `<script module>` + Cannot declare a variable with the same name as an import from `<script module>` ``` This incorrectly implies that the duplicate declaration itself is happening *inside* the module script block, rather than colliding with an import *from* that block. ## Changes Made | Action | Target (File / Function) | Description | | :--- | :--- | :--- | | **Template Fix** | `packages/svelte/messages/compile-errors/script.md` | Changed "inside" to "from" to accurately reflect the nature of the shadow collision. | | **Regenerated Errors** | `packages/svelte/src/compiler/errors.js` | Ran `pnpm generate` to apply the updated markdown template into the dictionary list. | | **Removed TODO** | `ensure_no_module_import_conflict` function | Removed the original `// TODO fix the message here` notation from the validator. | | **Test Adjustments** | `illegal-variable-declaration/errors.json` | Updated the validator test suite snapshots to assert against the correct error message format. | ## Validation Results * The error correctly throws when a user replicates this component structure. * Vitest suite `tests/validator/test.ts` successfully asserts the new, clearer message. --- ### 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.

Simon H	1773cb5b59	fix: ensure HMR wrapper forwards correct start/end nodes to active effect (#17985) ... Fixes #17982 (two issues reported there) Adding the start/end statically at the end once does not work because it's going to be stale when there's a HMR reload of the wrapped component. For reasons not completely clear to me it also fails in another case. So instead of wrapping the HMR with comments we just forward the nodes of the inner effect to the outer active effect, pretending the wrapper isn't there from a "remove dom nodes"-perspective.	3 weeks ago

moaaz	a94924b677	fix: export TweenOptions, SpringOptions, SpringUpdateOptions and Updater from svelte/motion (#17967) ... Exports `TweenedOptions`, `SpringOpts`, `SpringUpdateOpts`, and `Updater` from `svelte/motion`. These types are required for the public method signatures of `spring` and `tweened` (e.g., as parameters for `.set()` and `.update()`). This PR makes them accessible to TypeScript users, following the established pattern in modules like `svelte/store` and `svelte/transition`. Internal implementation details like `TickContext` remain private as they do not appear in any public-facing signatures.

Abishek Raj R R	7123bf3a13	fix: remove trailing semicolon from {@const} tag printer (#17962) ... Fixes #17720 ## Problem The `{@const}` tag was being printed with a trailing semicolon, producing invalid Svelte syntax like: {@const a = 1;} This happened because the `ConstTag` visitor in the printer was delegating to esrap's `VariableDeclaration` handler, which always appends a semicolon (correct for JS, but wrong for Svelte template syntax). ## Solution Instead of delegating to `VariableDeclaration`, the `ConstTag` visitor now manually prints the tag by: - Writing `{@const ` directly - Iterating through declarators and visiting each one - Separating multiple declarations with commas - Closing with `}` — no trailing semicolon ## Before {@const a = 1;} {@const a = 1, b = 2;} ## After {@const a = 1} {@const a = 1, b = 2} ## Changes - `packages/svelte/src/compiler/print/index.js` — fixed `ConstTag` visitor - `packages/svelte/tests/print/samples/const-tag/output.svelte` — updated expected test output --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Rich Harris <hello@rich-harris.dev> Co-authored-by: Rich Harris <rich.harris@vercel.com>	3 weeks ago
