`handle_prompt_end` is calling `is_device` and `is_directory` on the
path chosen by the user. However, this path is not necessarily unveiled.
Meaning that it the both functions results in an illegal operation.
This is a regression introduced with the usage of LibFileSystem in
1d24f394. This patch, revert the behavior at its previous state, i.e.
calling both functions with the fd provided by the FSAS.
This was previously a slightly confusing API. Even when there was no EOL
marker at the current location, we would still consume one byte.
It will now consume either EOL or nothing at all.
We would previously assume that, following the header, there must be a
valid PDF object that could be a linearization dict.
However, if the file is not linearized, this is not necessarily true.
We now try to detect if there even is an object, and don't treat
parsing errors as fatal.
As the current goal is to make our best effort loading documents, we
might as well ignore a broken header and power through, giving the user
a warning.
The stored ValueRecord in the font file only contains the fields
specified in the valueFormat field of the PairPosFormat1 table.
This means we need to construct the ValueRecord dynamically at runtime
and cannot bit_cast it to a struct.
read_value_record(u16 value_format, FixedMemoryStream& stream) takes
a bitmask value_format that describes the available fields of
the ValueRecord and a FixedMemoryStream at the location of the
next ValueRecord. It then advances the stream and returns a complete
ValueRecord.
When we create a Date object from a timestamp, or set its value by way
of Date.prototype.setTime, the timestamp is interpreted as UTC. Change
test expecatations against such instances to use UTC as well.
If it is default-initialized to 0, mktime will assume that DST is not in
effect for the specified time. Setting it to a negative value instructs
mktime to determine for itself whether DST is in effect.
At the moment, we only understand lookup type 2 (pair adjustment)
so let's ignore lookup tables with other types.
This fixes an issue where we'd choke on Noto Sans versions that come
with a chained context positioning lookup table (type 8).
Fixes#17924
The spec states that creating new windows "must be done without invoking
the focusing steps for the created browsing context". It also states we
should do so by "running the window open steps", but nowhere in those
steps is there an option to invoke or skip any focusing steps. So we do
so with a custom WebContent IPC parameter.
