The obsolete ttyname and ptsname syscalls are removed.
LibC doesn't rely on these anymore, and it helps simplifying the Kernel
in many places, so it's an overall an improvement.
In addition to that, /proc/PID/tty node is removed too as it is not
needed anymore by userspace to get the attached TTY of a process, as
/dev/tty (which is already a character device) represents that as well.
Previously, the ProjectBuilder searched for serenity library definitions
under Userland/Libraries.
However, not all libraries are defined there. For example, LibShell is
under Userland/Shell.
This helps make the overall codebase consistent. `class_name()` in
`Kernel` is always `StringView`, but not elsewhere.
Additionally, this results in the `strlen` (which needs to be done
when printing or other operations) always being computed at
compile-time.
Core::command() takes care of inserting the program name as the first
element in argv, and so we shouldn't include the program name in the
argument vector we give it.
The Shell's argument parsing logic tolerated the extra argument,
until 83609ad.
This fixes building serenity components in Hack Studio.
This will move the editors inside a tab widget and the user
will be able to add new editors as tabs as well as add new
tab widgets. The user will be able to easily switch between
editors as well as the tab widgets.
Currently we have a 'Project' menu with a 'New' menu in it, this tries
to organize things by just having one 'New...' sub-menu in the 'File'
menu that creates new files, projects and directories.
To solve conflicts, move 'Semantic Highlighting' to the 'View' menu.
As a result of both of these changes, remove 'Project' menu.
This commit adds "Filesystem Events" View to the Profiler. This tab
will present combined information for recorded Filesystem events.
Currently only accumulated count and duration is presented.
Duration amount currently only shows events that took over 1ms,
which means that in most cases 0 is show.
This matches the rename of RGBA32 to ARGB32. It also makes more sense
when you see it used with 32-bit hexadecimal literals:
Before:
Color::from_rgba(0xaarrggbb)
After:
Color::from_argb(0xaarrggbb)
...and implement SoftCPU::read_memory<T> with it.
This allows the MMU to read a typed object (using 1-byte reads), which
is significantly nicer to use than reading the struct fields manually.
Instead of making it hold the shadow data as another `T`, make it hold
the data as a byte array, and allow it to read the byte array as `T`.
This makes it much easier to make a "read_typed" function in the MMU.
Use the ErrorOr pattern with the Core::System wrappers to propagate more
errors from the TerminalWrapper.
The run_command method, when called with WaitForExit::Yes now returns an
error on command failure.
We now validate that the provided tag names are valid XML tag names,
and otherwise throw an "invalid character" DOM exception.
2% progression on ACID3. :^)
Also renames ServerConnectionWrapper=>ConnectionToServerWrapper
and ServerConnectionInstances=>ConnectionToServerInstances
This was done with CLion's automatic rename feature.
While trying out `ue --profile` today, I received an invalid json
profile. After poking around at the file it looks like we never close
the `events: [..` array that we generate, and thus end up with an
invalid document.
The fix is straight forward, always emit the closing brace.
Different thread highlights between widgets lead to different
visual weights between splitters, even when they have the same
width or height. This means some splitters look best at odd
sizes while others even. This sets the default spacing to the
most commonly used, depending on orientation, and adjusts
spacing for a few apps based on the new paint rect.
The most consistent look across apps requires some manual
tweaking occassionally. Knurlheads, use your discretion!
Splitters could be resized in such an order that all their remaining
children were fixed size, leading to unfillable gaps on resize events.
HackStudio and TextEditor already had logic to handle this edge case,
so this patch factors it into a general solution for all Splitters.
At least one widget is now guaranteed to be resizeable after a child
is removed.
Previously, the names of declarations where stored as a simple
StringView.
Because of that, we couldn't parse out-of-line function definitions,
which have qualified names.
For example, we couldn't parse the following snippet:
```
void MyClass::foo(){}
```
To fix this, we now store the name of a declaration with a
ASTNode::Name node, which represents a qualified named.
Previously there was some inconsistency between the apps when clicking
the "Open" action while the file wasn't saved.
Some programs (Font Editor) immediately asked you if you wanted to save
the modified file, while others (Text Editor, Hex Editor and Playground)
would show the save dialog only *after* you selected a file.
I think it's better to ask a user right away if they want to save file,
because a dialog after selecting a file should be generally related to
that selected file, like an error opening a file, an import window etc.
Previously, we stored a RefPtr to the HackStudioWidget in the
global scope.
This led to a destruction-order related use-after-free bug, where the
global HackStudioWidget instance destructed after the static-local
GUI::Clipboard instance.
When HackStudioWidget destructs it attempts to use the global Clipboard
instance, which had already been freed.
This caused the Hack Studio process to spin endlessly on exit because
it attempted to access the HashTable of the freed Clipboard object.
We now store a global WeakPtr to the HackStudioWidget instead, and
limit the lifetime of the object to the main function scope.
I've attempted to handle the errors gracefully where it was clear how to
do so, and simple, but a lot of this was just adding
`release_value_but_fixme_should_propagate_errors()` in places.
When requesting a parameter hint message with `Ctrl + p` in a file that
doesn't have a language server, we would crash.
Now, rather than verifying that we have a language server, we return
early if we don't have one.
Because the wake pipe is thread-local, it was previously not possible
to wake an event loop across a thread. Therefore, this commit
rearchitects event loop waking by making the wake function a member of
the event loop itself and having it keep a pointer to its thread's wake
pipe. The global wake() function calls wake on the current thread's
event loop.
This also fixes a bug in BackgroundAction: it should wake the event loop
it was created on, instead of the current thread's event loop.
