This is a simple getter and setter of the OscillatorType enum, with
error checking to not allow 'custom', as that should only be changed
through 'setPeriodicWave()'.
This is still missing a bunch of spec steps to construct the
audio node based on the parameters of the OscillatorNode, but it is at
least enough to construct an object to be able to add a basic test which
can get built upon as more is implemented.
If a function has the following properties:
- uses only local variables and registers
- does not use `this`
- does not use `new.target`
- does not use `super`
- does not use direct eval() calls
then it is possible to entirely skip function environment allocation
because it will never be used
This change adds gathering of information whether a function needs to
access `this` from environment and updates `prepare_for_ordinary_call()`
to skip allocation when possible.
For now, this optimisation is too aggressively blocked; e.g. if `this`
is used in a function scope, then all functions in outer scopes have to
allocate an environment. It could be improved in the future, although
this implementation already allows skipping >80% of environment
allocations on Discord, GitHub and Twitter.
Which currently will always throw an exception as it is unimplemented
under the hood - but this gives all of the plumbing we need in order to
create a oscillator node as used in the reduced turnstyle testcase.
An AudioNode is the fundamental building block used in 'Audio
Contexts'. In our immediate case, the audio node we are working towards
implementing is an oscillating source node.
This does two things:
* Clear exceptions when transferring control out of a finalizer
Otherwise they would resurface at the end of the next finalizer
(see test the new test case), or at the end of a function
* Pop one scheduled jump when transferring control out of a finalizer
This removes one old FIXME
Before this change both ExecutionContext and CallFrame were created
before executing function/module/script with a couple exceptions:
- executable created for default function argument evaluation has to
run in function's execution context.
- `execute_ast_node()` where executable compiled for ASTNode has to be
executed in running execution context.
This change moves all members previously owned by CallFrame into
ExecutionContext, and makes two exceptions where an executable that does
not have a corresponding execution context saves and restores registers
before running.
Now, all execution state lives in a single entity, which makes it a bit
easier to reason about and opens opportunities for optimizations, such
as moving registers and local variables into a single array.
The ReadableStreamPipeTo AO requires reading all chunks from a stream.
There actually isn't an AO defined to do that, so the "read all bytes"
implementation was changed to provide each chunk in a vector in commit
12cfa08a09.
This change makes reading all bytes a bit more uncomfortable in normal
use cases, as we now have to manually join the vector we receive. This
can also cause churn with huge allocations.
So instead, let's just provide an ad-hoc callback to receive each chunk
as they arrive.
Now that the chrome process is a singleton on all platforms, we can
safely add a cache to the CookieJar to greatly speed up access. The way
this works is we read all cookies upfront from the database. As cookies
are updated by the web, we store a list of "dirty" cookies that need to
be flushed to the database. We do that synchronization every 30 seconds
and at shutdown.
There's plenty of room for improvement here, some of which is marked
with FIXMEs in the CookieJar.
Before these changes, in a SQL database populated with 300 cookies,
browsing to https://twinings.co.uk/ WebContent spent:
19,806ms waiting for a get-cookie response
505ms waiting for a set-cookie response
With these changes, it spends:
24ms waiting for a get-cookie response
15ms waiting for a set-cookie response
When we try to start a long-running child process (e.g. a GUI app)
using a combination of the POSIX spawn and waitpid API, the Run
process ends up waiting for it to end before making any changes
to the path history. This leads to some confusion when trying to
fire up another Run process only to see that it did not save the
path to this program.
This PR resolves this by saving the path after it was created using
the POSIX spawn API.
This can cause issues with older versions of glibc warning when not
initializing the flexible array member for CMSG_DATA. Such as glibc
shipped with Ubuntu 20.04.
'set_frame_style' is what Frame itself uses to set the value, and a
significant number of GML files use 'frame_style' instead of just
'style', so let's switch to it and use it everywhere consistently.
Previously the GML compiler did not support object properties such as
`content_widget: @GUI::Widget{}` for GUI::ScrollableContainerWidget;
this commit adds support for such properties by simply calling
`set_<key>(<TProperty>&)` on the object.
This commit also removes the previous hack where
ScrollableContainerWidget was special-cased to have its singular child
used as the content widget; the only GML file using this behaviour was
also changed to be in line with 'proper' GML as handled by the GML
Playground.
