fix(upload, raf): fix transformFiles crash and #824 follow-ups - #1092
upload: transformFiles crash (regression from #1058)
#1058 changed transformFiles to iterate the FileList with for...in. That also visits the list's length and item members, so files[NaN] is undefined and .name throws on every call, even for an empty list. This breaks createFileUploader, the fileUploader directive and every createDropzone handler.
It now uses Array.from(files, file => ({ ... })).
New test/helpers.test.ts covers null, a real (empty) FileList, and a populated FileList-shaped object that includes length and item. The new tests fail on the current code.
Patch changeset.
Release order matters.main has upload at 0.1.6 from the last Version Packages run. That publish failed (npm E404), so 0.1.6 never reached npm. With this changeset the next release is 0.1.7. Please merge this before fixing npm publishing or re-running the failed release job; otherwise the broken 0.1.6 gets published.
useGlobalRAF registers a separate entry per call. Before, two owners registering the same callback shared one set entry, so one owner's remove() or cleanup unregistered the other's.
remove() only stops the shared loop when it removed the last callback. Before, disposing a callback that was never added stopped a loop started manually.
add and remove run untracked.
createCallbacksSet returns a callback typed (...args: Parameters<T>) => void instead of casting it as T.
The createScheduledLoop docs say schedule must keep repeating the callback until cancelled.
The README's useGlobalRAF examples no longer name the factory createScheduledLoop.
Tests:
Removed createRoot(async ...) with await vi.waitUntil, whose assertions ran after the test had finished.
Dispose a root that leaked, and tear down the singleton between tests.
Added regression tests for both useGlobalRAF bugs.
One assertion changed from 1 to 2 requestAnimationFrame calls: start() makes one request and the frame that runs makes another. The old value only passed because state leaked from the previous test; run on its own, the old test fails.
…follow-ups
upload: transformFiles iterated the FileList with for...in, which also
visits its `length` and `item` members, so it threw on every call
(regression from solidjs-community#1058, staged but unpublished as 0.1.6). Use
Array.from(files, ...) and add tests.
raf (follow-up to solidjs-community#824, unreleased):
- useGlobalRAF registers a separate entry per call, so two owners
registering the same callback no longer unregister each other
- remove() only stops the shared loop when it removed the last callback
- createCallbacksSet's dispatcher is typed (...args: Parameters<T>) => void
- document that createScheduledLoop's scheduler must repeat the callback
- fix tests whose assertions ran after the test ended, dispose leaked
roots, add regression tests
- add the new primitives to primitive.list and add a changeset

Walkthrough
The RAF package updates callback typing and global registration behavior, with corresponding tests, documentation, and package metadata. The upload package changes transformFiles to map FileList entries with Array.from and adds tests for null, empty, and populated inputs.
Changes: RAF callback handling
Layer / File(s)
Summary
Callback registration and loop behavior packages/raf/src/index.ts, packages/raf/test/index.test.ts, .changeset/raf-frameloop-utils.md
The callback dispatcher accepts the callback’s parameter tuple. useGlobalRAF stores a separate entry for each registration and stops the shared loop only when removal deletes the final entry. Tests cover independent registrations, removal, and synchronous cancellation.
Scheduler guidance and package metadata packages/raf/README.md, packages/raf/package.json
The README describes scheduler repetition and cancellation requirements, updates callback typing and examples, and package metadata lists the RAF utilities.
Upload FileList transformation
Layer / File(s)
Summary
FileList mapping and validation packages/upload/src/helpers.ts, packages/upload/test/helpers.test.ts, .changeset/upload-transform-files-crash.md
transformFiles maps FileList entries with Array.from and retains the existing output fields. Tests cover null and empty inputs, plus mapping populated input.
The changes fix the FileList crash in transformFiles and make useGlobalRAF registrations independent. Documentation, metadata, changesets, and tests are consistent with that behavior. No actionable merge-blocking risk remains.
