Add worker.setInterval, clearInterval, setTimeout, clearTimeout by extracting
the scheduling logic from Window and making it use Execution rather than Frame.
We want to take in account the pending frame in Runner._tick to continue
to process. If we use only the current frame, we will immediately return
in case of navigation.
During a root navigation, we keep the existing page active until we get
the headers callback from the pending page. Then
Session.commitPendingPage makes the switch.
It delays the deinit of CPD execution context to handle JS execution in
the meantime.
Now session has an array of two pages, _active_idx points to the main
page.
Both active and pending pages share the same frame_id, it must remains
stable. So this PR adds a Request.protect_from_abort to avoid removing
the request form the pending page when deinit the previous active page.
Follows previous changes to make a WebAPI worker-compatible by replacing any
dependency on *Frame with *js.Execute, *Page and/or *Session. The changes here
are relatively minor since most of the existing supporting WebApis (e.g. Blob,
Response, Request) have already been migrated.
Currently, variables (`attempt`, `listeners`) can be read/written to
concurrently from 2 threads (main + the sighandler thread). This opens up
some undefined behavior. More practically, what I'm seeing is that if I ctrl-c
quickly after a `zig build run` launch, the program appears to terminate but
remains running in the background.
Per HTML §4.11.1.2, a <summary>'s activation behavior runs the
toggle-details-state algorithm on its parent <details>, but only when
the summary is the first summary child of that details.
Frame.handleClick previously had no arm for .generic, so summary clicks
fell into `else => {}` and details.open never changed. Add a .generic
arm gated on `_tag == .summary` that walks the parent's element
children to confirm first-summary-child, then flips details.open via
the existing Details.setOpen.
Out of scope (tracked separately): firing ToggleEvent on the parent
(no ToggleEvent type yet); activating when a descendant of <summary>
is clicked (same gap exists for <a>/<label>; needs a broader walk-up
refactor of handleClick).
Tests: src/browser/tests/element/html/summary_click.html covers
closed→open, open→closed, non-first summary no-op, and orphan summary
no-op.
This comes from a WPT crash in /content-security-policy/blob/self-doesnt-match-blob.sub.html
The core issue is double-free on the request header list. This is a fundamental
issue about ambiguous ownership. On error, who's responsible for freeing the
request? The caller or the HttpClient. Answer: it depends when/where the error
happens. That just doesnt' work, and needs to be fixed. BUT....
There's also the issue that this specific test is failing because we aren't
properly encoding script URLs. This is a real and separate issue that also needs
to be fixed. That's what this commit does. In some ways, it's a bit superficial
because there's a real double-free issue, but this is a real issue to fix.
Follow up to https://github.com/lightpanda-io/browser/pull/2335 which hooks
into the tick's GC hint to close any closed window (rather than having to wait
until page unload).
Also, use schedule task for dispatchLoad which removes an check in every tick.
- Cache `ValidityState` per element so repeated `el.validity` access
returns the same instance (also avoids allocating a struct per
per-keystroke call).
- Use `Event.initTrusted` for the `invalid` event — browser-generated.
- Use `frame.dupeString(message)` (interns short strings) instead of
`frame.arena.dupe(u8, message)` for `setCustomValidity` storage.
- Cascade `*const Input` / `*const Select` through `getValidationMessage`,
`suffersValueMissing`, and Select.effectiveOption.
- Factor radio-group walking into a shared `radioGroupIterator`; add the
same-form check to `radioGroupHasChecked` (was only in
`uncheckRadioGroup`). The form comparison uses a frame-less helper so
it can run from the const validation path.
- Narrow `numericRangeBreach` to `.number, .range` — date/time/month/
week/datetime-local need type-specific conversion before comparison
(was silently returning false). TODO comment left in place.
- Add `getMinLength`/`setMinLength` getters to Input and TextArea, plus
`getMaxLength`/`setMaxLength` to TextArea (Input already had them).
Used internally by `suffersTooLong`/`suffersTooShort` and exposed via
IDL.
- TODO prefix on the file-input value-missing comment so the limitation
is greppable.
Tests cover the new IDL surface (`minLength`/`maxLength` on Input and
TextArea), the validity-state caching guarantee
(`el.validity === el.validity`), and the trusted-event flag on the
`invalid` event for Input, Select, TextArea, and Button.
Cannot Frame.deinit in window.close() as that's happening inside JS runtime.
Instead, defer on Page.deinit. This is MUCH later than necessary, but I'd like
to address the timing separately. This commit, as-is, prevents real crashes.
This is a follow up to https://github.com/lightpanda-io/browser/pull/2290. That
PR spit ScriptManager into ScriptManager and ScriptManagerBase, with the
goal of letting a Worker have a ScriptManagerBase that works without needing
a frame.
But the Script object was still a large object meant to work with any type of
script invocation, e.g. it has a nullable element. This commit swaps out these
fields for a better-typed "extra" union field. So that Element only exists in
the extra.frame tag. In the end, it just makes it more explicit about what
fields are valid under specific conditions.
