a8740f82eb CHttpJob: Collect the payload as a list of buffers during download 
Instead of growing the payload buffer as-we-go. This avoids wasting a
ton of time on buffer reallocation for non-trivial payloads.

3eb1a7f8f8 AK: Add a benchmark for parsing 4chan catalog JSON 
I was able to get parsing time down to about 1/3 of the original time
by using callgrind+kcachegrind. There's definitely more improvements
that can be made here, but I'm gonna be happy with this for now. :^)

b62a12c687 JsonParser: Some minor optimizations 
- Return more specific types from parse_array() and parse_object().
- Don't create a throwaway String in extract_while().
- Use a StringView in parse_number() to avoid a throwaway String.

93596dc00d JsonObject: Add move constructors for JsonObject(Json{Array,Object}&&) 
This also helps avoid JsonValue copying during parse.

82826104e0 Json: Add efficient copy and move constructors for Json{Array,Object} 
This helps avoid copying JsonValues during parsing.

cce2ea9bb0 AK: Add StringView::to_int() 
This is a shameless copy-paste of String::to_int(). We should find some
way to share this code between String and StringView instead of having
two duplicate copies like this.

c55129e573 JsonParser: Use Vector<char, 1024> instead of StringBuilder in parsing 
This is a 10-12% speedup on the 4chan thread catalog JSON.

030891531b ChanViewer: Start working on a simple read-only 4Chan viewer 
Since they are nice enough to provide a JSON API over HTTP, this makes
for a perfect way to exercise our networking code a bit. :^)

210550d4b3 JsonArray: Expose the value vector to the outside for convenience 
Sometimes it's easier to just work with a const Vector<JsonValue>&,
so give clients the option of doing that.

675aa550a4 Kernel: Put IPv4 and TCP related debug spam behind flags 
...and turn those flags off for now, to make it possible to write some
networking code without being spammed to death.

273d9d6cf5 CHttpJob: If no "Content-Length" header was received, read until EOF 
Instead of aborting after receiving the first chunk, we have to keep
reading until EOF.

f37c8f618b Terminal: Paint bold text with a bold font. 
This was really straightforward since all the necessary pieces were
already in place. This patch just passes a bold font to draw_glyphs()
for buffer cells with the bold attribute set. :^)
 2019-08-04 08:15:30 +02:00
Andreas Kling
7d08116a6d LibDraw: Add Font::default_bold_fixed_width_font() 
We need a way to get a bold version of the default fixed-width font.

116d551f82 IPCCompiler: Don't generate "OwnPtr<void>" as a handle() return type 
This was happening for async (response-less) messages, since they were
returning void and were were always just wrapping the return type in
an OwnPtr no matter what.

0f0b00dc1f Lagom: Add a simple IPC client and server for host-side testing 
Add LibIPC to the Lagom build, and also implement two little test apps
so we can run IPC tests on other systems.

8e684f0959 AudioServer: Port to the new generated IPC mechanism 
Fork the IPC Connection classes into Server:: and Client::ConnectionNG.
The new IPC messages are serialized very snugly instead of using the
same generic data structure for all messages.

Remove ASAPI.h since we now generate all of it from AudioServer.ipc :^)
 2019-08-03 19:49:19 +02:00

3519b6c201 IPCCompiler: More work towards AudioServer bringup 
- Add IEndpoint::handle(IMessage), a big switch table on message type.
  handle() will return a response message for synchronous messages,
  and return nullptr otherwise.
- Use i32 instead of int for everything
- Make IMessage::encode() const
- Make IEndpoint::decode_message() static, this allows template code to
  decode messages without an endpoint instance on hand.

18aeda2e0d BufferStream: It's not an error to read up to the very end of a buffer 
Don't signal an error before we've reached the very end of the buffer.
 2019-08-03 19:20:05 +02:00
Andreas Kling
6e956f2a0b BufferStream: Add operator<<(const char*) overload 
Ext2FS was relying on the presence of a (StringView) overload here and
when I added a (bool) overload, it started choosing that for literals.
 2019-08-03 19:02:48 +02:00
Andreas Kling
3c1bad99a2 AudioServer: Link against LibIPC 
We're not using any of the functionality yet, but soon...

8dd07c3075 IPCCompiler: Emit message parameter getters 
For simplicity's sake, they are all "const type& name() const"

c255cedd7a IPCCompiler: Make decode_message() return nullptr for unknown messages 2019-08-03 17:06:24 +02:00

925c8f42f8 IPCCompiler: Generate message decoding functions 
An endpoint now knows how to decode a ByteBuffer into an IMessage.

4fc15c9e6e AudioServer: The EnqueueBuffer response needs a success boolean 
This was already in the current version of the code, I'm just updating
the soon-to-be-current IPC protocol version of it. :^)

36b352554e IPCCompiler: Emit message constructors + include ID in serialization 2019-08-03 16:35:49 +02:00
Andreas Kling
05e08afcd8 IPCCompiler: Generate getters for message ID's and message names 
Each endpoint namespace will have an enum class MessageID where you can
find all of its messages.
 2019-08-03 16:19:14 +02:00
Andreas Kling
fae3091999 IPCCompiler: Typedef the response message types as "ResponseType" 
Each message will now have a typedef called ResponseType as an alias
for the expected response type. This will aid in implementing the sync
messaging code.
 2019-08-03 16:06:40 +02:00
Andreas Kling
016335edde IPCCompiler: Generate endpoint and message classes 
These are not entirely finished but it's starting to take shape. :^)

a40e763b2a LibIPC: Start fleshing out a separate IPC library 
This will be a place to put object serialization/deserialization logic,
message parsing, endpoint management, etc.
 2019-08-03 15:29:40 +02:00
Andreas Kling
aa8a3d4a89 IPCCompiler: Start working on a simple IPC definition language 
Instead of doing everything manually in C++, let's do some codegen.
This patch adds a crude but effective IPC definition parser, along
with two initial definition files for the AudioServer's client and
server endpoints.

c5903ec4bb AK: Remove two redundant RefPtr constructors. 
We already have constructors for "const T*" and "const T&" so we don't
need to have non-const variants.

69281c22d4 FontEditor(UI): Update the groupbox to have the right background color 2019-08-03 11:39:34 +02:00

47511b5930 GWidget: Implement set_backcolor() and set_forecolor() 
These are set-color-from-string variants used by the VisualBuilder's
code generator.
 2019-08-03 11:35:10 +02:00
Andreas Kling
54c77cb714 GVariant: Try to do color string parsing in GVariant::to_color() 
If the underlying variant type is a String, try to parse out a color
when to_color() is called.

This makes VisualBuilder apply the saved colors when loading forms.
 2019-08-03 11:34:02 +02:00
Andreas Kling
e43b27a3fa LibDraw: Add Color::from_string(StringView) 
This parses hex colors in either #RRGGBBAA or #RRGGBB format.
No other formats are supported at the moment.

f511421aaa Kernel+ProcessManager: Add some more info to /proc/PID/fds 
- "seekable": whether the fd is seekable or sequential.
- "class": which kernel C++ class implements this File.
- "offset": the current implicit POSIX API file offset.
 2019-08-03 08:42:40 +02:00

7f25959fa2 LibCore: Make get_current_user_home_path() return String & close passwd 
This API was returning a "const char*" and it was unclear who took care
of the underlying memory. Returning a String makes that obvious.

Also make sure we close the /etc/passwd file when we're done with it.
 2019-08-03 08:32:07 +02:00
Andreas Kling
8a703c0076 ProcessManager: Add a new per-proces "open files" view showing open FDs 
This uses the data from /proc/PID/fds with ease now that it's JSON. :^)

33b0c4cfaf LibAudio: Explicitly ignore IPC postprocessing requests 
We don't need to do any IPC postprocessing in LibAudio (yet.)
This is the mechanism used by LibGUI to do repaint coalescing etc.

7c7343de98 Kernel: mount() should fail if the provided device is not a disk device 
In the future, we should allow mounting any block device. At the moment
there is too much filesystem code that depends on the underlying device
being a DiskDevice.

a6fb055028 Kernel: Generalize VFS metadata lookup and use it in mount() and stat() 
Refactored VFS::stat() into VFS::lookup_metadata(), which can now be
used for general VFS metadata lookup by path.

ae4d707684 Kernel: Align the KResult value storage appropriately. 
We should figure out how to convert this code to using AK::Result.
