2020-02-06LibGfx: Unpublish Gfx::Rect from global namespaceAndreas Kling
2020-02-06LibGfx: Rename from LibDraw :^)Andreas Kling
2020-02-06LibDraw: Put all classes in the Gfx namespaceAndreas Kling
I started adding things to a Draw namespace, but it somehow felt really wrong seeing Draw::Rect and Draw::Bitmap, etc. So instead, let's rename the library to LibGfx. :^)
2020-02-05SystemMonitor: Fix building with clangjoshua stein
2020-02-02LibGUI: Put all classes in the GUI namespace and remove the leading GAndreas Kling
This took me a moment. Welcome to the new world of GUI::Widget! :^)
2020-02-02LibCore: Put all classes in the Core namespace and remove the leading CAndreas Kling
I've been wanting to do this for a long time. It's time we start being consistent about how this stuff works. The new convention is: - "LibFoo" is a userspace library that provides the "Foo" namespace. That's it :^) This was pretty tedious to convert and I didn't even start on LibGUI yet. But it's coming up next.
2020-02-02LibGUI: Add GHBoxLayout and GVBoxLayout convenience classesAndreas Kling
2020-01-30SystemMonitor: Unveil /devSergey Bugaev
DevicesModel wants to match devices supported by the kernel to device nodes in /dev.
2020-01-27LibGUI: Add 64-bit signed integer support to GVariantAndreas Kling
What was previously the "Int" type is now "Int32" and "Int64".
2020-01-24Meta: Claim copyright for files created by meSergey Bugaev
This changes copyright holder to myself for the source code files that I've created or have (almost) completely rewritten. Not included are the files that were significantly changed by others even though it was me who originally created them (think HtmlView), or the many other files I've contributed code to.
2020-01-23AK: Let's call decrementing reference counts "unref" instead of "deref"Andreas Kling
It always bothered me that we're using the overloaded "dereference" term for this. Let's call it "unreference" instead. :^)
2020-01-21SystemMonitor: Show process unveil() state as "Veil"Andreas Kling
A process has one of three veil states: - None: unveil() has never been called. - Dropped: unveil() has been called, and can be called again. - Locked: unveil() has been called, and cannot be called again.
2020-01-21SystemMonitor: Use unveil()Andreas Kling
2020-01-20SystemMonitor: Add an "Unveiled paths" section to the per-process tabsAndreas Kling
This shows the data from /proc/PID/unveil in a nice table view. :^)
2020-01-18Meta: Add license header to source filesAndreas Kling
As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.
2020-01-17Kernel: Add "accept" pledge promise for accepting incoming connectionsAndreas Kling
This patch adds a new "accept" promise that allows you to call accept() on an already listening socket. This lets programs set up a socket for for listening and then dropping "inet" and/or "unix" so that only incoming (and existing) connections are allowed from that point on. No new outgoing connections or listening server sockets can be created. In addition to accept() it also allows getsockopt() with SOL_SOCKET and SO_PEERCRED, which is used to find the PID/UID/GID of the socket peer. This is used by our IPC library when creating shared buffers that should only be accessible to a specific peer process. This allows us to drop "unix" in WindowServer and LookupServer. :^) It also makes the debugging/introspection RPC sockets in CEventLoop based programs work again.
2020-01-15SystemMonitor: Unbreak the memory stats graphAndreas Kling
It was never updating because we'd just seek the start of /proc/memstat over and over, which didn't generate new contents. Instead, open the file on every iteration.
2020-01-12Applications+DevTools+MenuApplets: Drop "unix" pledge when possibleAndreas Kling
Now that the "unix" pledge is no longer required for socket I/O, we can drop it after making the connections we need in a program. In most GUI program cases, once we've connected to the WindowServer by instantiating a GApplication, we no longer need "unix" :^)
2020-01-12SystemMonitor: Add "proc" pledge so we can send signals to processesAndreas Kling
2020-01-11SystemMonitor: Use pledge()Andreas Kling
2020-01-11SystemMonitor+LibCore: Show process pledges in SystemMonitor :^)Andreas Kling
2020-01-11SystemMonitor: Display mount flagsSergey Bugaev
2020-01-08SystemMonitor: Put the Frequency menu items in an action groupAndreas Kling
This makes them look like radio buttons in the menu, which is a very nice increase in polish. :^)
2020-01-02Kernel: Create support for PCI ECAMLiav A
The new PCI subsystem is initialized during runtime. PCI::Initializer is supposed to be called during early boot, to perform a few tests, and initialize the proper configuration space access mechanism. Kernel boot parameters can be specified by a user to determine what tests will occur, to aid debugging on problematic machines. After that, PCI::Initializer should be dismissed. PCI::IOAccess is a class that is derived from PCI::Access class and implements PCI configuration space access mechanism via x86 IO ports. PCI::MMIOAccess is a class that is derived from PCI::Access and implements PCI configurtaion space access mechanism via memory access. The new PCI subsystem also supports determination of IO/MMIO space needed by a device by checking a given BAR. In addition, Every device or component that use the PCI subsystem has changed to match the last changes.
2020-01-01AK: Move the userspace SharedBuffer from LibC to AKAndreas Kling
This always felt out-of-place in LibC.
2020-01-01Applications: Add new keyboard shortcuts & update few existing onesJami Kettunen
2019-12-31Applications: Space out SystemMonitor & TextEditor in AboutDialogsJami Kettunen
2019-12-30Kernel: Refactor scheduler to use dynamic thread prioritiesAndreas Kling
Threads now have numeric priorities with a base priority in the 1-99 range. Whenever a runnable thread is *not* scheduled, its effective priority is incremented by 1. This is tracked in Thread::m_extra_priority. The effective priority of a thread is m_priority + m_extra_priority. When a runnable thread *is* scheduled, its m_extra_priority is reset to zero and the effective priority returns to base. This means that lower-priority threads will always eventually get scheduled to run, once its effective priority becomes high enough to exceed the base priority of threads "above" it. The previous values for ThreadPriority (Low, Normal and High) are now replaced as follows: Low -> 10 Normal -> 30 High -> 50 In other words, it will take 20 ticks for a "Low" priority thread to get to "Normal" effective priority, and another 20 to reach "High". This is not perfect, and I've used some quite naive data structures, but I think the mechanism will allow us to build various new and interesting optimizations, and we can figure out better data structures later on. :^)
2019-12-29Kernel+SystemMonitor: Expose amount of per-process clean inode memoryAndreas Kling
This is memory that's loaded from an inode (file) but not modified in memory, so still identical to what's on disk. This kind of memory can be freed and reloaded transparently from disk if needed.
2019-12-29Kernel+SystemMonitor: Expose amount of per-process dirty private memoryAndreas Kling
Dirty private memory is all memory in non-inode-backed mappings that's process-private, meaning it's not shared with any other process. This patch exposes that number via SystemMonitor, giving us an idea of how much memory each process is responsible for all on its own.
2019-12-25Build: support library and generator dependenciesjoshua stein
Instead of directly manipulating LDFLAGS, set LIB_DEPS in each subdirectory Makefile listing the libraries needed for building/linking such as "LIB_DEPS = Core GUI Draw IPC Core". This adds each library as an -L and -l argument in LDFLAGS, but also adds the library.a file as a link dependency on the current $(PROGRAM). This causes the given library to be (re)built before linking the current $(PROGRAM), but will also re-link any binaries depending on that library when it is modified, when running make from the root directory. Also turn generator tools like IPCCompiler into dependencies on the files they generate, so they are built on-demand when a particular directory needs them. This all allows the root Makefile to just list directories and not care about the order, as all of the dependency tracking will figure it out.
2019-12-24LibGUI+LibDraw: Add "Palette" concept for scoped color themingAndreas Kling
GApplication now has a palette. This palette contains all the system theme colors by default, and is inherited by a new top-level GWidget. New child widgets inherit their parents palette. It is possible to override the GApplication palette, and the palette of any GWidget. The Palette object contains a bunch of colors, each corresponding to a ColorRole. Each role has a convenience getter as well. Each GWidget now has a background_role() and foreground_role(), which are then looked up in their current palette when painting. This means that you no longer alter the background color of a widget by setting it directly, rather you alter either its background role, or the widget's palette.
2019-12-24SystemMonitor: Remove uneeded cast from unsigned to intShannon Booth
GVariant now supports unsigned ints :^)
2019-12-23WindowServer+LibGUI: Implement basic color themingAndreas Kling
Color themes are loaded from .ini files in /res/themes/ The theme can be switched from the "Themes" section in the system menu. The basic mechanism is that WindowServer broadcasts a SharedBuffer with all of the color values of the current theme. Clients receive this with the response to their initial WindowServer::Greet handshake. When the theme is changed, WindowServer tells everyone by sending out an UpdateSystemTheme message with a new SharedBuffer to use. This does feel somewhat bloated somehow, but I'm sure we can iterate on it over time and improve things. To get one of the theme colors, use the Color(SystemColor) constructor: painter.fill_rect(rect, SystemColor::HoverHighlight); Some things don't work 100% right without a reboot. Specifically, when constructing a GWidget, it will set its own background and foreground colors based on the current SystemColor::Window and SystemColor::Text. The widget is then stuck with these values, and they don't update on system theme change, only on app restart. All in all though, this is pretty cool. Merry Christmas! :^)
2019-12-21Kernel: Expose region executable bit in /proc/PID/vmAndreas Kling
Also show it in SystemMonitor's process memory map table (as 'X') :^)
2019-12-20Build: clean up build system, use one shared Makefilejoshua stein
Allow everything to be built from the top level directory with just 'make', cleaned with 'make clean', and installed with 'make install'. Also support these in any particular subdirectory. Specifying 'make VERBOSE=1' will print each ld/g++/etc. command as it runs. Kernel and early host tools (IPCCompiler, etc.) are built as object.host.o so that they don't conflict with other things built with the cross-compiler.
2019-12-15Kernel+SystemMonitor: Prevent userspace access to process ELF imageAndreas Kling
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.)
2019-12-15SystemMonitor: Make the memory map the "default view"Andreas Kling
The memory map is a lot more interesting than the "open files" view :^)
2019-12-15Kernel+SystemMonitor: Expose the number of set CoW bits in each RegionAndreas Kling
This number tells us how many more pages in a given region will trigger a CoW fault if written to.
2019-12-09LibGUI: Make GMenu inherit from CObjectAndreas Kling
This is primarily to make it possible to pass a GMenu* where a CObject* is expected.
2019-12-09SystemMonitor: Show information about purgeable memoryAndreas Kling
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.
2019-12-08SystemMonitor: Show thread name instead of process nameAndrew Kaster
Add the thread name to CThreadStatistics and display it in the system monitor's process model instead of the process name.
2019-12-02SystemMonitor: Enable sorting by column in the process memory map viewAndreas Kling
2019-12-02SystemMonitor: Update the process memory map once every secondAndreas Kling
2019-12-01Kernel+SystemMonitor: Log amounts of I/O per threadAndreas Kling
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.
2019-11-26Kernel: Make syscall counters and page fault counters per-threadAndreas Kling
Now that we show individual threads in SystemMonitor and "top", it's also very nice to have individual counters for the threads. :^)
2019-11-26Kernel: Expose per-thread information in /proc/allAndreas Kling
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.
2019-11-17Kernel+SystemMonitor: Show VM region "shared" and "stack" bits in UIAndreas Kling
Expose these two region bits through /proc/PID/vm and show them in the SystemMonitor process memory map view.
2019-11-09Kernel+SystemMonitor: Publish can_read/write state for open filesAndreas Kling
The can_read() and can_write() states for file descriptions are now published in /proc, allowing SystemMonitor to display it.
2019-11-04SystemMonitor: Add device column to filesystems tabYour Name
