Every process keeps its own ELF executable mapped in memory in case we
need to do symbol lookup (for backtraces, etc.)
Until now, it was mapped in a way that made it accessible to the
program, despite the program not having mapped it itself.
I don't really see a need for userspace to have access to this right
now, so let's lock things down a little bit.
This patch makes it inaccessible to userspace and exposes that fact
through /proc/PID/vm (per-region "user_accessible" flag.)
The squad is complete :^)
You can find the equation for the triangle wave here:
https://en.wikipedia.org/wiki/Triangle_wave
We're using this one:
|x mod 4 - 2| - 1
Modifications have been made to correct the frequency and phase:
|(4x + 1) mod 4 - 2| - 1
The white noise is generated by calling rand() and dividing it by
RAND_MAX to get a value from 0 to 1. Then it's adjusted to fit between
-1 and 1.
This adds a context menu to the TreeView with the ability to copy/paste, create
new directories, etc. This does not address the issue mentioned above where
using the global application shortcut does not apply to whatever view has
focus.
This patch exposes some fields about purgeable memory regions.
We now also show total purgeable volatile and non-volatile memory in
the big process table.
Using int was a mistake. This patch changes String, StringImpl,
StringView and StringBuilder to use size_t instead of int for lengths.
Obviously a lot of code needs to change as a result of this.
Ref: #826
Right-clicking a directory no longer has the "Open in TextEditor" entry.
Right-clicking the directory view now allows you to create a new directory.
Currently, when `set_text()` is called on GTextDocument a change is
triggered and all clients registered get a document_did_set_text
call. This in turn causes the TextEditorWidget to mark the document
as dirty even on the first open, which makes for a weird experience.
This is a tiny bar at the left of the taskbar where you can put
your most used apps to launch them with a single click. In a way,
it's another replacement for the Launcher, in addition to the app
menu. Unlike the launcher and the menu, it's not meant to be the
primary way to launch apps; it's only a faster way to launch a few
most often used utilities.
We now show a quick window outline animation when going in/out of
minimized state. It's a simple 10 frame animation at 60fps, just to
give a visual cue of what's happening with the window.
The Taskbar sends over the corresponding button rect for each window
to the WindowServer using a new WM_SetWindowTaskbarRect message.
Note that when unminimizing, we still *show* the window right away,
and don't hold off until the animation has finished. This avoids
making the desktop feel slow/sluggish. :^)
Fixes#825
The logic already existed. I just moved it to a separate lambda then added it
to the appropriate action. Note that when the tree view refreshes, it seems to
randomly open trees. I would like to fix this in a separate PR.
This patch introduces code generation for the WindowServer IPC with
its clients. The client/server endpoints are defined by the two .ipc
files in Servers/WindowServer/: WindowServer.ipc and WindowClient.ipc
It now becomes significantly easier to add features and capabilities
to WindowServer since you don't have to know nearly as much about all
the intricate paths that IPC messages take between LibGUI and WSWindow.
The new system also uses significantly less IPC bandwidth since we're
now doing packed serialization instead of passing fixed-sized structs
of ~600 bytes for each message.
Some repaint coalescing optimizations are lost in this conversion and
we'll need to look at how to implement those in the new world.
The old CoreIPC::Client::Connection and CoreIPC::Server::Connection
classes are removed by this patch and replaced by use of ConnectionNG,
which will be renamed eventually.
Goodbye, old WindowServer IPC. You served us well :^)
This patch adds these I/O counters to each thread:
- (Inode) file read bytes
- (Inode) file write bytes
- Unix socket read bytes
- Unix socket write bytes
- IPv4 socket read bytes
- IPv4 socket write bytes
These are then exposed in /proc/all and seen in SystemMonitor.
Previously it was not possible to see what each thread in a process was
up to, or how much CPU it was consuming. This patch fixes that.
SystemMonitor and "top" now show threads instead of just processes.
"ps" is gonna need some more fixing, but it at least builds for now.
Fixes#66.
This opens the source of the current document in TextEditor.
For file:// URLs, we open the local file, but for all other protocols,
a temporary file is generated, containing the document source.
Longer-term we should build some kind of viewer into the Browser app
instead. That would avoid silly problems like how this forgets to
delete the temporary files, for instance :^)
Instead of implicitly copying whatever you select, and pasting when you
middle-click, let's have traditional copy and paste actions bound to
Ctrl+Shift+C and Ctrl+Shift+V respectively.
This patch adds pthread_create() and pthread_exit(), which currently
simply wrap our existing create_thread() and exit_thread() syscalls.
LibThread is also ported to using LibPthread.
The Launcher's functionality has been replaced by the app shortcuts in
the system menu.
There were various window management hacks to ensure that the launcher
stayed below all other windows while also being movable, etc.
