Previously, we had a special ASTNode for class members,
"MemberDeclaration", which only represented fields.
This commit removes MemberDeclaration and instead uses regular
Declaration nodes for representing the members of a class.
This means that we can now also parse methods, inner-classes, and other
declarations that appear inside of a class.

Previously, AK::Function would accept _any_ callable type, and try to
call it when called, first with the given set of arguments, then with
zero arguments, and if all of those failed, it would simply not call the
function and **return a value-constructed Out type**.
This lead to many, many, many hard to debug situations when someone
forgot a `const` in their lambda argument types, and many cases of
people taking zero arguments in their lambdas to ignore them.
This commit reworks the Function interface to not include any such
surprising behaviour, if your function instance is not callable with
the declared argument set of the Function, it can simply not be
assigned to that Function instance, end of story.

This changes the INI and GML lexers to conform to the now-fixed
rendering of syntax highlighting spans in GUI::TextEditor.
The other user of GMLToken::m_end, GMLAutocompleteProvider, has been
modified to take into account that end position columns have been
incremented by one.

Previously, when traversing the ClassView tree to find the parent of a
new node, we used the name of the node's declaration to find the path
to the parent in the tree.
However, some nodes in the tree do not have a matching declaration,
which caused a VERIFY failure.
To fix this, we now use the node's name when walking the tree.
We can do this because the node's name should be identical to the name
of its declaration.
Closes #7702.

This isn't used anymore so let's remove it entirely.

Previously Profiler was using timestamps to distinguish processes.
However it is possible that separate processes with the same PID exist
at the exact same timestamp (e.g. for execve). This changes Profiler
to use unique serial numbers for each event instead.

The previous check of looking at `/proc/PID` was not working, it would
always fail even if the process was indeed inspectable.
Commit 70117781 introduced a new IPC for asking InspectorServer whether
or not a given `pid` is actually inspectable.
If a process is not inspectable, the `GUI::ProcessChooser` is
redisplayed if it was previously displayed, otherwise it exits.
|
|
The profiler tried to be clever when handling process_exit events by
subtracting one from the timestamp. This was supposed to ensure that
events after a process' death would be attributed to the new process
in case the old process used execve(). However, if there was another
event (e.g. a CPU sample) at the exact same time the process_exit
event was recorded the profile would fail to load because we
didn't find the process anymore.
This changes introduces a new problem where samples would be attributed
to the incorrect process if a CPU sample for the old process, a
process_exit as well as a process_create event plus another CPU sample
event for the new process happened at the exact same time. I think
it's a reasonable compromise though.

This is a pretty fundamental refactor of the way
CppComprehensionEngine works.
Previously, in order to answer queries such as "goto definition" or
"autocomplete", we would do ad-hoc logic of walking the AST,
collecting available declaration nodes, computing scopes, and so on.
This commit introduces an architectural change where each Document
builds a hashmap of symbols on creation.
With these hashmaps, it's easier to iterate over all of the available
symbols, and to answer a query such as "which symbols are defined in
this scope".

They were sorta unneeded. :^)

Previously Profiler (e.g. when started via the context menu in
SystemMonitor) would request logging _all_ event types. While this
might be useful at a later point in time the lack of event type
filtering in the profile viewer makes this less useful because
showing different event types in the same timeline shows an inaccurate
picture of what was really going on.
Some event types (like kmalloc) happen more frequently than others
(e.g. CPU samples) and while they don't carry the same weight they
would still dominate the samples graph.
This changes the Profiler app to just do CPU sampling for now.

This adds __attribute__((used)) to the function declaration so the
compiler doesn't discard it. It also makes the function NEVER_INLINE
so that we don't end up with multiple copies of the function. This
is necessary because the function uses inline assembly to define some
unique labels.
|
|
This fixes a null dereference when toggling the "top functions" mode
while a top-level process node was selected.
|
|
This looks a lot nicer than starting with a plain GUI::Widget.
|
|
Since the introduction of multi-select, we have had both `on_selection`
and `on_selection_change`, the latter of which was only invoked when a
change in selection came in through the model.
This removes `AbstractView::on_selection` and replaces it usage with
the more explicit `on_selection_change` everywhere.
|
|
|
|
We had two functions for doing mostly the same thing. Combine both
of them into String::find() and use that everywhere.
Also add some tests to cover basic behavior.

Previously each malloc size class would keep around a limited number of
unused blocks which were marked with MADV_SET_VOLATILE which could then
be reinitialized when additional blocks were needed.
This changes malloc() so that it also keeps around a number of blocks
without marking them with MADV_SET_VOLATILE. I termed these "hot"
blocks whereas blocks which were marked as MADV_SET_VOLATILE are called
"cold" blocks because they're more expensive to reinitialize.
In the worst case this could increase memory usage per process by
1MB when a program requests a bunch of memory and frees all of it.
Also, in order to make more efficient use of these unused blocks
they're now shared between size classes.

The HashMap API was overkill and made using this less ergonomic than
it should be.
|

|
|
This is no longer used by any of our IPC pairs.

|
There's no need to wait for a response after we've sent the project
path to a newly connected language server.

|
We were not taking the width of the process headers into account when
computing the scrollable content size of the timeline.
Fix this by passing the header width to AbstractScrollableWidget's
set_size_occupied_by_fixed_elements().

I've had a couple of instances where a profile was missing process
creation events for a PID. I don't know how to reproduce it yet,
so this patch merely adds a helpful debug message so you know why
Profiler is failing to load the file.
|
|
This patch adds an additional level of hierarchy to the call tree:
Every process gets its own top-level node. :^)
Before this, selecting multiple processes would get quite confusing
as all the call stacks from different processes were combined together
into one big tree.
|
|
Also rename the "LibThread" namespace to "Threading"

The C++ language-server can now autocomplete include paths.
Paths that start with '<' will be searched in /usr/include, and paths
that start with '"' will be searched in the project's root directory.
|
|
|
|
autocomplete_property => try_autocomplete_property
autocomplete_name => try_autocomplete_name
This makes it more clear that these variants may fail because e.g
the node is not a property / not a name.

Problem:
- Default destructors (and constructors) are in `.cpp` files. This
prevents the compiler's optimizer from inlining them when it thinks
inlining is appropriate (unless LTO is used).
- Forward declarations can prevent some optimizations, such as
inlining of constructors and destructors.
Solution:
- Remove them or set them to `= default` and let the compiler handle
the generation of them.
- Remove unneeded forward declarations.

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).

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.

Instead use default_font().bold_variant() in cases where we want a bold
variant of the default font. :^)

Previously, ASTNode::dump() used outln() for output, which meant it
always wrote its output to stdout.
After this commit, ASTNode::dump() receives an 'output' argument (which
is stdout by default). This enables writing the output to somewhere
else.
This will be useful for testing the LibCpp Parser with the output of
ASTNode::dump.
|
|
This is similar to the LibJS test data that resides in
/home/anon/js-tests.
It's more convenient than storing the test programs as raw strings
in the code.
