The plugins build that runs on master currently uses the same ccache key
as non-plugin builds in PRs. This means all clang PR builds are not able
to use ccache.
Move the plugins build to a separate job. This job also has sanitizers
disabled to make the plugins build quicker.
Before this change, :hover wouldn't match anything outside the shadow
boundary when hovering elements inside a shadow tree. This was most
noticeable when hovering the text inside an input element and hover
styles disappearing from the hosting input element itself.
This creates a TimeZoneWatcher in the UI process to inform all open
WebContent processes when the time zone changes. The WebContent process
will clear its time zone cache to retrieve a fresh zone the next time
it is asked for one.
This creates platform-dependent monitors to detect when the system time
zone changes. On Linux, we use a file watcher to monitor files such as
/etc/localtime for changes. On macOS, this uses CFNotificationCenter to
be notified by the OS when the time zone changes.
Note: the macOS implementation requires running in a process which is
running the CoreFoundation event loop. Both the AppKit and Qt chromes
are doing so in the UI process, but this means we cannot run this
monitor in the WebContent process.
It's expensive to determine the system time zone from disk each time it
is requested. This makes LibUnicode cache the result, and provides an
API to clear that cache. This will let us set up a monitor to watch for
system time zone changes in platform-dependent ways.
When asked to monitor a file (not a directory), we often need to instead
monitor the parent directory to receive FS events. For example, when a
symbolic link is deleted/created, we don't receive any events unless we
are watching the parent.
The monitored files can be internally removed by inotify. If we then try
to explicitly remove them, the inotify_rm_watch call will fail. We do
this when the file is deleted and we receive an IN_DELETE event. This
ensures we clean up the monitored files.
According to the inotify man page, this event is always generated after
a IN_DELETE, which we separately handle. Just ignore IN_IGNORED events
to avoid spamming stderr.
We *could* even skip creating a paintable for hidden nodes, but that
means that dynamic updates to the CSS visibility property would require
mutating the paint tree, so let's keep it simple for now.
Previously, only DOM nodes with `is_editable()` allowed selection via
the mouse. This had the unwanted consequence, that read-only
input/textarea elements did not allow selection.
Now, `EventHandler::handle_mousedown()` asks the node's non-shadow
parent element over the new virtual method `is_child_node_selectable()`,
if selection of the node is allowed.
This method is overridden for `HTMLButtonElement` and
`HTMLInputElement`, to disallow selection of buttons and placeholders.
Fixes#579
We were incorrectly looking at the CSS computed values for width and
height to determine the natural size of <svg> root elements.
This meant that elements where the attribute and computed value were
different values would end up with incorrect natural size.
The spec requires that "multipart/form-data" Content-Type headers also
include a boundary directive. This allows the content server to validate
the submitted form data.
Google Lens, for example, rejects forms missing this directive.
