These functions return the deprecated `Core::File` class, so let's mark
it as such to avoid possible confusion between future non try_*
functions which will use Core::Stream family classes and to possibly
grab someone's attention. :^)
When we were asked to make a new preview text, we first generated the
whole file in the /tmp directory and then read the first 8 lines to put
them in a text box. This was doing a bit of unnecessary work at first,
but more importantly, didn't work on a given file descriptor from
FileSystemAccessServer as we were copying a file to a filename instead,
meaning that we also had to unveil the whole home directory.
Anyway, previews will be written now to a MemoryStream by the generator,
which will limit to 8 lines. File saves will omit /tmp entirely,
allowing us to tighten program unveil list a little. :^)
This change allows for cursor navigation of a forumula while editing
rather than having to use the mouse to edit the cursor position within
a cell. Tab and Enter still allow you to navigate out of the cell to
next row or columns. :)
Rip that bandaid off!
This does the following, in one big, awkward jump:
- Replace all uses of `set_main_widget<Foo>()` with the `try` version.
- Remove `set_main_widget<Foo>()`.
- Rename the `try` version to just be `set_main_widget` because it's now
the only one.
The majority of places that call `set_main_widget<Foo>()` are inside
constructors, so this unfortunately gives us a big batch of new
`release_value_but_fixme_should_propagate_errors()` calls.
In 7c5e30daaa, the focus was "only" on
Userland/Libraries/, whereas this commit cleans up the remaining
headers in the repo, and any new badly-formatted include.
Using set_fixed_width prevents the splitter from resizing, so it has
been changed to set_preferred_width. Added a FIXME that I'm not
familiar enough with the codebase to tackle yet.
This addresses issue #16589
This constructor was easily confused with a copy constructor, and it was
possible to accidentally copy-construct Objects in at least one way that
we dicovered (via generic ThrowCompletionOr construction).
This patch adds a mandatory ConstructWithPrototypeTag parameter to the
constructor to disambiguate it.
`Core::Stream::File` shouldn't hold any utility methods that are
unrelated to constructing a `Core::Stream`, so let's just replace the
existing `Core::File::exists` with the nicer looking implementation.
Note that js_rope_string() has been folded into this, the old name was
misleading - it would not always create a rope string, only if both
sides are not empty strings. Use a three-argument create() overload
instead.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Before this change, each AST node had a 64-byte SourceRange member.
This SourceRange had the following layout:
filename: StringView (16 bytes)
start: Position (24 bytes)
end: Position (24 bytes)
The Position structs have { line, column, offset }, all members size_t.
To reduce memory consumption, AST nodes now only store the following:
source_code: NonnullRefPtr<SourceCode> (8 bytes)
start_offset: u32 (4 bytes)
end_offset: u32 (4 bytes)
SourceCode is a new ref-counted data structure that keeps the filename
and original parsed source code in a single location, and all AST nodes
have a pointer to it.
The start_offset and end_offset can be turned into (line, column) when
necessary by calling SourceCode::range_from_offsets(). This will walk
the source code string and compute line/column numbers on the fly, so
it's not necessarily fast, but it should be rare since this information
is primarily used for diagnostics and exception stack traces.
With this, ASTNode shrinks from 80 bytes to 32 bytes. This gives us a
~23% reduction in memory usage when loading twitter.com/awesomekling
(330 MiB before, 253 MiB after!) :^)
C++20 can automatically synthesize `operator!=` from `operator==`, so
there is no point in writing such functions by hand if all they do is
call through to `operator==`.
This fixes a compile error with compilers that implement P2468 (Clang
16 currently). This paper restores the C++17 behavior that if both
`T::operator==(U)` and `T::operator!=(U)` exist, `U == T` won't be
rewritten in reverse to call `T::operator==(U)`. Removing `!=` operators
makes the rewriting possible again.
See https://reviews.llvm.org/D134529#3853062
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
We previously put the generated headers in SOURCES, which did not mark
them as GENERATED (and did not produce a proper dependency).
This commit moves all generated headers into GENERATED_SOURCES, and
removes useless header SOURCES.
This is a partial revert of commit 7af5eef. After 97d15e9, the 'proc'
promise is not needed for operations using getsid().
This also fixes launching several applications in which 7af5eef added
the 'proc' promise only in the second call to pledge().
This commit does three things atomically:
- switch over Core::Account+SystemServer+LoginServer to sid based socket
names.
- change socket names with %uid to %sid.
- add/update necessary pledges and unveils.
Userland: Switch over servers to sid based sockets
Userland: Properly pledge and unveil for sid based sockets
URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.

This has two advantages: First the picker no longer changes the active
window state of its parent. Visually this is an additional hint that the
dialog is "fragile" and will close on loss of focus. Second, because
it contains a search box, its own input won't be preempted by global
application shortcuts when typing (pending #15129). This is a problem
in apps like PixelPaint which use shortcuts without modifiers.
Currently, LibUnicodeData contains the generated UCD and CLDR data. Move
the UCD data to the main LibUnicode library, and rename LibUnicodeData
to LibLocaleData. This is another prepatory change to migrate to
LibLocale.
And adjust some GML properties. Since a808cfa, splitters grow
opportunistically. Setting them to fixed sizes now quite literally
fixes them in place. Fixes immovable splitters missed in the
aforementioned commit.
Intrinsics, i.e. mostly constructor and prototype objects, but also
things like empty and new object shape now live on a new heap-allocated
JS::Intrinsics object, thus completing the long journey of taking all
the magic away from the global object.
This represents the Realm's [[Intrinsics]] slot in the spec and matches
its existing [[GlobalObject]] / [[GlobalEnv]] slots in terms of
architecture.
In the majority of cases it should now be possibly to fully allocate a
regular object without the global object existing, and in fact that's
what we do now - the realm is allocated before the global object, and
the intrinsics between both :^)
with the CaptureInput WindowMode. This mode will serve the same
function as accessories: redirecting input while allowing parent
windows to remain active.
The basic idea is that a global object cannot just come out of nowhere,
it must be associated to a realm - so get it from there, if needed.
This is to enforce the changes from all the previous commits by not
handing out global objects unless you actually have an initialized
realm (either stored somewhere, or the VM's current realm).
- Prefer VM::current_realm() over GlobalObject::associated_realm()
- Prefer VM::heap() over GlobalObject::heap()
- Prefer Cell::vm() over Cell::global_object()
- Prefer Wrapper::vm() over Wrapper::global_object()
- Inline Realm::global_object() calls used to access intrinsics as they
will later perform a direct lookup without going through the global
object
This is needed so that the allocated NativeFunction receives the correct
realm, usually forwarded from the Object's initialize() function, rather
than using the current realm.
Global object initialization is tightly coupled to realm creation, so
simply pass it to the function instead of relying on the non-standard
'associated realm' concept, which I'd like to remove later.
This works essentially the same way as regular Object::initialize() now.
Additionally this allows us to forward the realm to GlobalObject's
add_constructor() / initialize_constructor() helpers, so they set the
correct realm on the allocated constructor function object.
This is a continuation of the previous six commits.
The global object is only needed to return it if the execution context
stack is empty, but that doesn't seem like a useful thing to allow in
the first place - if you're not currently executing JS, and the
execution context stack is empty, there is no this value to retrieve.
This is a continuation of the previous five commits.
A first big step into the direction of no longer having to pass a realm
(or currently, a global object) trough layers upon layers of AOs!
Unlike the create() APIs we can safely assume that this is only ever
called when a running execution context and therefore current realm
exists. If not, you can always manually allocate the Error and put it in
a Completion :^)
In the spec, throw exceptions implicitly use the current realm's
intrinsics as well: https://tc39.es/ecma262/#sec-throw-an-exception
This is a continuation of the previous three commits.
Now that create() receives the allocating realm, we can simply forward
that to allocate(), which accounts for the majority of these changes.
Additionally, we can get rid of the realm_from_global_object() in one
place, with one more remaining in VM::throw_completion().
