When viewing the code side-by-side with the spec, it's much nicer when
everything is in the same order.
Also fixes the spec link for Date.prototype.getMilliseconds (it pointed
at setMilliseconds by mistake).
If the tzname is unknown, fall back to UTC for now. Unknown time zones
are most likely due to not parsing RULE entries yet, but at the very
least, it only makes sense for current_time_zone to return a time zone
that LibTimeZone actually knows about.
The only purpose of the remap() in Region::try_clone() is to ensure
non-writable page table entries for CoW regions. If a region is already
non-writable, there's no need to waste time updating the page tables.
When mapping or unmapping completely inaccessible memory regions,
we don't need to update the page tables at all. This saves a bunch of
time in some situations, most notably during dynamic linking, where we
make a large VM reservation and immediately throw it away. :^)
We were already only tracking kernel regions, this patch just makes it
more clear by having it reflected in the name of the registration
helpers.
We also stop calling them for userspace regions, avoiding some spinlock
action in such cases.
This optimization was added when region lookup was O(n), before we had
the O(log n) RedBlackTree. Let's remove it to simplify the code, as we
have no evidence that it remains valuable.
Since the build now happens in Build/$SERENITY_ARCH/ and not in Build/,
this updates check-symbols.sh to use the correct directory to check the
LibC symbols in. For some reason, the constant failures did not show
up as errors in CI.
Previously we would only remove them from the map if they were attached
to an AddressSpace, even though we would always add them to the map on
construction. This results in an assertion failure on destruction if
the page directory was never attached to an AddressSpace. (for example,
on an allocation failure of said AddressSpace)
This change unfortunately cannot be atomically made without a single
commit changing everything.
Most of the important changes are in LibIPC/Connection.cpp,
LibIPC/ServerConnection.cpp and LibCore/LocalServer.cpp.
The notable changes are:
- IPCCompiler now generates the decode and decode_message functions such
that they take a Core::Stream::LocalSocket instead of the socket fd.
- IPC::Decoder now uses the receive_fd method of LocalSocket instead of
doing system calls directly on the fd.
- IPC::ConnectionBase and related classes now use the Stream API
functions.
- IPC::ServerConnection no longer constructs the socket itself; instead,
a convenience macro, IPC_CLIENT_CONNECTION, is used in place of
C_OBJECT and will generate a static try_create factory function for
the ServerConnection subclass. The subclass is now responsible for
passing the socket constructed in this function to its
ServerConnection base; the socket is passed as the first argument to
the constructor (as a NonnullOwnPtr<Core::Stream::LocalServer>) before
any other arguments.
- The functionality regarding taking over sockets from SystemServer has
been moved to LibIPC/SystemServerTakeover.cpp. The Core::LocalSocket
implementation of this functionality hasn't been deleted due to my
intention of removing this class in the near future and to reduce
noise on this (already quite noisy) PR.
Similar to File::adopt_fd, this function creates a new LocalSocket with
an existing fd. The main use of this function is to create LocalSocket
objects from fds that have been passed to us by SystemServer to take
over.
This uses recv with MSG_DONTWAIT to disable blocking operation for a
single call. LibIPC uses this to read in a non-blocking manner from an
otherwise blocking socket.
Implements support for `glRasterPos` and updating the raster position's
window coordinates through `glBitmap`. The input for `glRasterPos` is
an object position that needs to go through the same vertex
transformations as our regular triangles.
Aplay's documentation is updated to reflect the new -s flag.
Additionally, "sound" has been replaced by "audio", reflecting the
application name. (It's also a more general term in my opinion, but
that's debatable.)
By default, aplay now prints the played time, the remaining time and the
total duration of the file in seconds and minutes. This is much more
intuitive. The old sample-based format is kept and hidden behind the -s
flag.
The format of these names is "Full Abbreviation (.fileformat)". For
example: "FLAC (.flac)", "RIFF WAVE (.wav)", "MPEG Layer III (.mp3)",
"Vorbis (.ogg)" The reasoning is that the container and therefore the
file ending may differ significantly from the actual format, and the
format should be given as unambiguously as possible and necessary.
