REGRESSION(309394@main): [GLib] Web process launch aborts for unix:
PULSE_SERVER values and abstract D-Bus addresses
https://bugs.webkit.org/show_bug.cgi?id=326070
Reviewed by Adrian Perez de Castro.
Two conversions from C string handling to spans in 309394@main lose
information at the edges of the string:
bindPulse() takes the socket path with span().subspan(5), which drops the
null terminator, so UTF8CStringView::fromUTF8() fails its RELEASE_ASSERT and
the UI process aborts as soon as a web process is launched with
PULSE_SERVER=unix:/path. Take the subspan from spanIncludingNullTerminator().
directoryContainingDBusSocket() tests the result of StringView::find() for
truth, but notFound is SIZE_MAX. For a unix: address without a path=
component, such as the unix:abstract= addresses dbus-launch produces, the
offset wraps to 4 and the function hands bubblewrap a relative path under the
current directory, which does not exist. The xdg-dbus-proxy launch then fails
and the UI process aborts with "Failed to fully launch dbus-proxy". Compare
against notFound, restoring the pre-309394@main behaviour of binding nothing.
