Process-separated symbolication was cute, but ultimately the threat
model is kinda silly. We're already *running* the binary, but we're
afraid to parse its symbol table? :^)
This commit makes SystemMonitor and bt do symbolication in-process.
SymbolServer and the symbol user will be removed separately.
This changes (context) menus across the system to conform to titlecase
capitalization and to not underline the same character twice (for
accessing actions with Alt).
We were leaking the "view source" and "downloading file" windows for
some reason, presumably it was necessary when these were first added.
Since they are owned by the spawning browser window, there's no need
to leak them.
Problem:
- `typedef`s are read backwards making it confusing.
- `using` statements can be used in template aliases.
- `using` provides similarity to most other C++ syntax.
- C++ core guidelines say to prefer `using` over `typedef`:
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rt-using
Solution:
- Switch these where appropriate.
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.
This unifies how 3DFileViewer handles the initial file when starting
the application and when opening files later on via the menu.
Errors are shown both for the initial load as well as when loading
files later on. An error during file load no longer clears the
existing model.
It also adds support for specifying the filename as a command-line
argument.
The opened file's name is shown in the titlebar.
The HTML and Markdown preview modes both use an OutOfProcessWebView to
render the preview pane, and we were instantiating this view from GML.
This caused us to always spawn a WebContent process alongside every
TextEditor instance.
Fix this by deferring the OOPWV construction until we actually need it.
This makes launching TextEditor on a text file quite a bit faster. :^)
This makes a few modifications to the statusbar text generation:
* Use the canonical U+XXXX representation of unicode characters.
* For control characters, display their alias instead of whitespace.
* Substitute RTL codepoints with U+FFFD so the text paints correctly.
* Only show the glyph's dimensions if it actually exists in the font.
This fixes#7286.
Previously, this code would create a bitmap with the size of the screen
resolution, draw the new wallpaper into it, and then scale it down for
display inside the MonitorWidget.
This was done on every paint event, which made the code quite slow and
allocation-happy.
Instead of this, we now scale down the new wallpaper to a miniature
of the same scale as the little MonitorWidget screen. The miniature is
then used for tiling, etc. The miniature is cached and reused across
paint events if nothing else changes.
An application that allows opening arbitrary files from the filesystem
needs to allow itself to access the filesystem, otherwise there's no
point in supporting the feature. :^)
And the "thread" pledge is needed for background thumbnail generation.
It is too complex because it supports many options that are not
used by the search engine. It just makes format validation more
complicated.
Additionaly, now it's possible to have { } characters in search
engine URL (although they are not valid URL characters) :)
Previously <AK/Function.h> also included <AK/OwnPtr.h>. That's about to
change though. This patch fixes a few build problems that will occur
when that change happens.
When reloading a page multiple times, it was also added multiple
times to the history. This commit prohibits an url to be added
twice in a row.
Fixes#7264

It was very confusing for every Tab to have their own GUI::Menubar that
got dynamically swapped in/out when switching tabs.
This change moves us to a single menubar per window, and BrowserWindow
is the owner of its own menubar.
When holding ctrl and scrolling, the page will be zoomed in an out.
When zoomed in on a page, scrolling with move vertically up and down
the page (or horizontally if shift is being held).
In order to speed up zooming, zoomed bitmaps are cached per-page at
each distinct zoom level. This cache is cleared every 30 seconds to
prevent OOM problems.
When right-clicking with no selected row in the process list,
SystemMonitor would still show a context menu. This disables
the context menu if index is invalid and also disables Alt+Enter
so that build_process_window() is never called with a PID of -1.
Fixes#7167.
Having so much the logic and lambdas in main() was getting unwieldy.
Moving it into a class simplifies this, and also opens up a path
towards supporting "Open in New Window" :^)
Previously ByteBuffer would internally hold a RefPtr to the byte
buffer and would behave like a reference type, i.e. copying a
ByteBuffer would not create a duplicate byte buffer, but rather
two objects which refer to the same internal buffer.
This also changes ByteBuffer so that it has some internal capacity
much like the Vector<T> type. Unlike Vector<T> however a byte
buffer's data may be uninitialized.
With this commit ByteBuffer makes use of the kmalloc_good_size()
API to pick an optimal allocation size for its internal buffer.
Previously deleting an animated image wouldn't make the animation timer
stop. This resulted in the animation still running in the ViewWidget.
Moreover the timer wasn't stopped when loading different images, which
led to high CPU usage when going from an animated image to a
non-animated one.
Previously some actions like Rotate/Flip/Set as Desktop Wallpaper would
make the application crash if no image was loaded. Now image actions are
enabled/disabled based on whether an image has been loaded or not.
By using fstatat during file system analyzation instead of lstat, we
reduce the amount of work the kernel has to do for each stat call.
During profiling it came up that the kernel was spending a lot of time
resolving paths. Because each call to stat passed an absolute path the
kernel had to do the same work over and over again.
When using relative paths the kernel only has to resolve the relative
part as it can reuse the already resolved path of the base directory.
Instead of parsing untrusted and potentially malicious image files in
the ImageViewer GUI process, take advantage of the ImageDecoder service
that we already have on the system to sandbox the decode.
This prevents bugs in our image decoding libraries from being used as
an exploitation vector when viewing files in ImageViewer.
Single-process Browser forces a connection to these services early on,
to avoid having to unveil their paths. I'm suspicious of the benefits
of this (and the comment about it wasn't even accurate) but let's keep
it for now.
In multi-process mode, there's no need to do this, and in fact it was
causing us to spawn two extra totally unused processes.
Since applications using Core::EventLoop no longer need to create a
socket in /tmp/rpc/, and also don't need to listen for incoming
connections on this socket, we can remove a whole bunch of pledges!
It's frustrating when the system is under heavy load and you want to
investigate using SystemMonitor, but SystemMonitor chokes on the lag.
Let's at give it a fighting chance by maxing out the main thread prio.
Not sure why some menus did have one and others didn't, even in the
same application - now they all do. :^)
I added character shortcuts to some menu actions as well.
Seeing " - Browser" for loading pages is annoying, so let's do something
more sensible instead for empty tab document titles: "<URL> - Browser".
Also consolidate the two places where this code is used into a lambda to
make any future changes easier.
Instead of having the window non-resizable, it now defaults to a frame
size of 200 x 200 pixels but is user-resizable. The shown screenshot
updates its size accordingly. :^)
Sometimes we might need a larger view, or a non-square shape.
Introduce the ability to hide the Analog Clock window borde. With this
feature enabled it looks like the clock is floating and integrated into
the desktop.
The "Cube Demo" has the same feature, and was used as inspiration when
implementing the feature in the Analog Clock.
UndoStack will now merge adjacent commands *if they want to be merged*
instead of bundling everything you push onto it until you tell it
to "finalize the combo."
This uses less memory and gives applications full control over how
their undo stacks end up. :^)
This was quite unreliable before. Changes to the undo stack's modified
state are now reflected in the document's modified state, and the
GUI::TextEditor widget has its undo/redo actions updated automatically.
UndoStack is still a bit hard to understand due to the lazy coalescing
of commands, and that's something we should improve upon (e.g with more
explicit, incremental command merging.) But for now, this is a nice
improvement and undo/redo finally behaves in a way that feels natural.
Only keep track of that (and eventually close() it) internally instead.
This argument is not present on other systems, so we were running into
compatibility issues with ports.
Also bring the implementation closer to Linux and OpenBSD by making sure
to close the slave pty fd in the fork()'d child as well as _exit()'ing
on login_tty() failure - it's non-POSIX, so those are our references
here. :^)
* Remove unnecessary #include statements
* Move it into the TextEditor namespace
* Mark the single-argument constructor explicit
* Use move() to avoid some unnecessary copies
This also moves Widget::load_from_json into Core::Object as a virtual
function in order to allow loading non-widget objects in GML (e.g.
BoxLayout).

This changes client methods so that they return the IPC response's
return value directly - instead of the response struct - for IPC
methods which only have a single return value.
This commit unifies methods and method/param names between the above
classes, as well as adds [[nodiscard]] and ALWAYS_INLINE where
appropriate. It also renamed the various move_by methods to
translate_by, as that more closely matches the transformation
terminology.
This allows the user to specify a specific line and column number to
start at when opening a file in TextEditor through the terminal, by
adding a colon after the file name.
For example, `TextEditor ReadMe.md:10:5` will open ReadMe.md and put
the cursor on line 10 at column 5.
To ensure that the user isn't trying to open a file that actually has
colons in its name, it checks if the file exists before parsing.
Replaces the feature added in b474f49164Closes#5589
Instead of tracking this stuff ourselves at the application level,
we now just act as an intermediary and pass along the information to
the windowing system.
Updated Spreadsheet to use the new way of converting a number to a
String represenation using the alphabet.
The code responsible for this conversion now lives in AK/String, so it
gets deleted from Spreadsheet.cpp.
We had some inconsistencies before:
- Sometimes "The", sometimes "the"
- Sometimes trailing ".", sometimes no trailing "."
I picked the most common one (lowecase "the", trailing ".") and applied
it to all copyright headers.
By using the exact same string everywhere we can ensure nothing gets
missed during a global search (and replace), and that these
inconsistencies are not spread any further (as copyright headers are
commonly copied to new files).
If you start a URL with a '?' character, the Browser will use the
user-selected search engine (none by default).
For now, there are several engines hardcoded and there is no support
for custom search engines.
The current ProtocolServer was really only used for requests, and with
the recent introduction of the WebSocket service, long-lasting
connections with another server are not part of it. To better reflect
this, this commit renames it to RequestServer.
This commit also changes the existing 'protocol' portal to 'request',
the existing 'protocol' user and group to 'request', and most mentions
of the 'download' aspect of the request to 'request' when relevant, to
make everything consistent across the system.
Note that LibProtocol still exists as-is, but the more generic Client
class and the more specific Download class have both been renamed to a
more accurate RequestClient and Request to match the new names.
This commit only change names, not behaviors.
The WebSocket bindings match the original specification from the
WHATWG living standard, but do not match the later update of the
standard that involves FETCH. The FETCH update will be handled later
since the changes would also affect XMLHttpRequest.
This patch implements a couple of enhancements to the synthesizer
engine:
* Each track has a volume control.
* The input and tooltips for all controls are improved.
* The noise channel is pitched, which allows for basic drum synthesis.
As many macros as possible are moved to Macros.h, while the
macros to create a test case are moved to TestCase.h. TestCase is now
the only user-facing header for creating a test case. TestSuite and its
helpers have moved into a .cpp file. Instead of requiring a TEST_MAIN
macro to be instantiated into the test file, a TestMain.cpp file is
provided instead that will be linked against each test. This has the
side effect that, if we wanted to have test cases split across multiple
files, it's as simple as adding them all to the same executable.
The test main should be portable to kernel mode as well, so if
there's a set of tests that should be run in self-test mode in kernel
space, we can accomodate that.
A new serenity_test CMake function streamlines adding a new test with
arguments for the test source file, subdirectory under /usr/Tests to
install the test application and an optional list of libraries to link
against the test application. To accomodate future test where the
provided TestMain.cpp is not suitable (e.g. test-js), a CUSTOM_MAIN
parameter can be passed to the function to not link against the
boilerplate main function.
Instead of storing the function names (in a badly named Vector<String>)
and source ranges separately, consolidate them into a new struct:
TracebackFrame. This makes it both easier to use now and easier to
extend in the future.
Unlike before we now keep each call frame's current node source range
in the traceback frame next to the function name, meaning we can display
line and column numbers outside of the VM and after the call stack is
emptied.
The Piano application used to perform very poorly due to unnecessary
draw calls. This is solved with two optimziations:
1. Don't draw the widgets as often as possible. The widgets are instead
at least updated every 150ms, except for other events.
2. Don't re-draw the entire piano roll sheet. The piano roll background,
excluding in-motion objects (notes, the play cursor), is only re-drawn
when its "viewport" changes.
A minor drawback of this change is that notes will appear on top of the
pitch labels if placed at the left edge of the roll. This is IMO
acceptable or may be changed by moving the text to the "foreground".
GlyphBitmap width is currently limited to twiddling 32 bits so
abide by a 32x36 standard for now. Fixes incorrect line values and
ranges and removes unused RefPtr.

Problem:
- `constexpr` functions are additionally decorated with `inline`
keyword. This is redundant since `constexpr` implies `inline`.
Solution:
- Remove redundancies.
did_error() caused the program to crash since the DialogBox tried to
run its own Notifier with the same - now invalid because closed - fd.
In addition to setting the member that is the Notifier to nullptr we
also tell the Notifier that it is not enabled anymore.
This replaces the glyph width spinbox in the font editor with a
checkbox when editing fixed width fonts that indicates if the
currently selected character's glyph is present in the edited font
(For variable width fonts a non zero width implies presence)
This commit also changes the background color of glyphs in the glyph
map based on the presence of each specific glyph in the font.
