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.
We now try to open image files dropped on us from FileManager. :^)
The QuickShow code is not exactly well-factored, and should be fixes up
to not do the same thing twice, etc.
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.
This simple helper escapes '<', '>' and '&' so they can be used in HTML
text without interfering with the parser.
Use this in IRCClient to prevent incoming messages from messing with
the DOM :^)
Renamed "Position" to "Elapsed". "channel/channels" automatically
changes now when more than one channel exist. The current file name
is now displayed in the window title.
This seemed like a perfect fit for LibHTML. We can now style the IRC
channels and queries however we like with the power of HTML and CSS.
This patch doesn't do much in the way of styling, it just gets the
basic mechanism into place.
When attempting to open a file that doesnt exist or has permission
problems, the application would end after hitting OK on the message
box instead of starting up to an empty editor.
I believe this has something to do with the dialog event loop
interfering with the application event loop, or possibly the fact
that the window creation code is in the show() method.
To work around this I now call the open_file() method after the
show() method.
Instead of quitting the application immediately when the pty gives an
EOF, fire an on_command_exit hook so the TerminalWidget client can
decide for himself what to do.
Instead, have TerminalWidget provide an on_title_change hook.
This allows embedders to decide for themselves what to do if we receive
a "set terminal title" escape sequence.
When embedding a TerminalWidget, you might not want it to automatically
update its own size policy based on the exact terminal buffer size.
This behavior is now passed as a flag to the TerminalWidget constructor
which makes it behave nicely both inside HackStudio and in Terminal.
If you had made a change to the first 4 bits of a byte and then changed
your offset via keyboard or menu option it would change the last 4 bits
of the new offset the next time you made a change and would not show that
the byte had been changed at the new offset.
This patch implements basic support for <a href="#foo"> fragment links.
To figure out where we actually want to scroll to, we have to do
something different based on the layout node's box type. So if it's a
regular LayoutBox we can just use the LayoutBox::position().
However, if it's an inline layout node, we use the position of the
first line box fragment in the containing block contributed by this
layout node or one of its descendants.
HtmlView will now invoke the on_link_hover hook when the cursor enters
or leaves a DOM node that has an enclosing link element.
This patch also updates the meaning of Node::enclosing_link_element()
to find the nearest HTMLAnchorElementAncestor *with an href attribute*.
Minor patch, but I was watching one of your videos on YouTube and
thought that the pop-up was unecessary/annoying in this case. Love
your enthusiasm for the project :^)
The layout root is now kept alive via Document::m_layout_root.
This will allow us to do more layout-related things inside the inner
layer of LibHTML without reaching out to the HtmlView.
I'd like to keep HtmlView at a slightly higher level, to prevent it
from getting too complex.
This patch also fixes accidental disconnection of the layout tree from
the DOM after doing a layout tree rebuild. ~LayoutNode() now only
unsets the DOM node's layout_node() if it's itself.
For now this is simply a counter+hook exposed by ResourceLoader and
shown in the Browser status bar.
This is not very nuanced, and it would be nice to expose more info so
we could eventually do something like a progress bar.
Node.normalize() is a standard DOM API that coalesces Text nodes.
To avoid clashing with that, rename it to fixup().
This patch also makes it happen automagically as part of parsing.
Instead of HtmlView clients having to worry about parsing and loading
the default CSS, just take care of it inside StyleResolver.
The default style is automatically inserted into the stylesheet list,
at the very start, so everyone else gets a chance to override it.
We now use GLazyWidget for all the secondary tabs, which makes the
program start up way faster than before.
There's a noticeable delay when you click on the "PCI Devices" tab
for the first time, but that's definitely better than always eating
that delay before seeing a window at all. :^)
If we resize/maximize the window, we might end up with some lines in
history that had a different length than the current terminal width.
That's okay, so let's not crash because of it.
Fixes#620.
This patch adds three separate per-process fault counters:
- Inode faults
An inode fault happens when we've memory-mapped a file from disk
and we end up having to load 1 page (4KB) of the file into memory.
- Zero faults
Memory returned by mmap() is lazily zeroed out. Every time we have
to zero out 1 page, we count a zero fault.
- CoW faults
VM objects can be shared by multiple mappings that make their own
unique copy iff they want to modify it. The typical reason here is
memory shared between a parent and child process.
GFilePicker
- Fixed GFilePicker to use new ref-counted construct method to stop crashing on open dialog.
- PaintBrush is still crashing on open dialog due to an unrelated issue.
PaintBrush
- Created 16x16 icon for PaintBrush
- Moved Open option into App menu.
- Changed help menu to make use of the standardized About dialog.
GEventLoop was just a dummy subclass of CEventLoop anyway. The only
thing it actually did was make sure a GWindowServerConnectionw was
instantiated. We now take care of that in GApplication instead.
CEventLoop is now non-virtual and a little less confusing. :^)
Okay, I've spent a whole day on this now, and it finally kinda works!
With this patch, CObject and all of its derived classes are reference
counted instead of tree-owned.
The previous, Qt-like model was nice and familiar, but ultimately also
outdated and difficult to reason about.
CObject-derived types should now be stored in RefPtr/NonnullRefPtr and
each class can be constructed using the forwarding construct() helper:
auto widget = GWidget::construct(parent_widget);
Note that construct() simply forwards all arguments to an existing
constructor. It is inserted into each class by the C_OBJECT macro,
see CObject.h to understand how that works.
CObject::delete_later() disappears in this patch, as there is no longer
a single logical owner of a CObject.
Subclasses of CNetworkJob handle this by overriding shutdown().
This patch implements it for CHttpJob by simply tearing down the
underlying socket.
We also automatically call shutdown() after the job finishes,
regardless of success or failure. :^)
The C_OBJECT macro now also inserts a static construct(...) helper into
the class. Now we can make the constructor(s) private and instead call:
auto socket = CTCPSocket::construct(arguments);
construct() returns an ObjectPtr<T>, which we'll later switch to being
a NonnullRefPtr<T>, once everything else in in place for ref-counting.
The delete action now actually deletes files (after asking the user for
confirmation, of course.) Deleting directories is not yet supported.
Fixes#541.
Fix a crash when opening a folder, and another one when trying to open
a newly created folder.
It was not safe to modify a GModelSelection while it's being iterated over.
Fixes#536.
When the user has scrolled up and begins typing, the scrollbar will
automatically return them to the current cursor position so that they
can see what they're typing.
The program will now automatically select the user's currently
chosen resolution when it is loaded up, however it is not
"visually selected" in the `GListView`
Moved the `resolution_list` list to be on the top to keep it consistent
with the wallpaper tab.
As was mentioned in #556, the `DisplayProperties` Wallpaper tab
contained a lot of "extra space", in which half the tab was taken up
by the list of wallpapers. The rest of that space is now reserved for
a wallpaper preview, so the user can see the selected image before
applying it.
When copying a list of files to the clipboard, we now use the special
data type "file-list".
This allows us to have the paste action's enabled state reflect the
actual ability to paste something. :^)
Based on whether something is selected or not. I added a FIXME about
the paste action, since that will require some more coordination with
the system clipboard.
An interactive application to modify the current display settings, such as
the current wallpaper as well as the screen resolution. Currently we're
adding the resolutions ourselves, because there's currently no way to
detect was resolutions the current display adapter supports (or at least
I can't see one... Maybe VBE does and I'm stupid). It even comes with
a very nice template'd `ItemList` that can support a vector of any type,
which makes life much simpler.
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)
This is not as perfect as it is elsewhere in the system, as we cannot
really change how terminal "thinks about" characters and bytes. What
we can do though, and what this commit does, is to *render* emojis, but
make it seem as if they take up all the space, and all the columns their
bytes would take if they were all regular characters.
