Notifying a Resource's clients may lead to arbitrary JS execution,
so we can't rely on the ResourceClient pointers remaining valid.
Use WeakPtr to avoid this problem.
This patch introduces a caching mechanism in ResourceLoader. It's keyed
on a LoadRequest object which is what you provide to load_resource()
when you want to load a resource.
We currently never prune the cache, so resources will stay in there
forever. This is obviously not gonna stay that way, but we're just
getting started here. :^)
This should drastically reduce the number of requests when loading
some sites (like Twitter) that reuse the same images over and over.
A Resource represents a resource that we're loading, have loaded or
will soon load. Basically, it's a downloadable resource that can be
shared by multiple clients.
A typical usecase is multiple <img> elements with the same src.
In a future patch, we will try to make sure that those <img> elements
get the same Resource if possible. This will reduce network usage,
memory usage, and CPU usage. :^)
For now, this first patch simply introduces the mechanism.
You get a Resource by calling ResourceLoader::load_resource().
To get notified about changes to a Resource's load status, you inherit
from ResourceClient and implement the callbacks you're interested in.
This patch turns HTMLImageElement into a ResourceClient.
This commit makes LibLine handle interrupts (as reported via
interrupted() and resized()) again.
There is a little catch with the shell:
```
$ ls |
pipe> <C-c> (prompt stays here until a key is pressed)
```
You can still run the old parser with "br -O", but the new one is good
enough to be the default parser now. We'll fix issues as we go and
eventually remove the old one completely. :^)
When parsing JavaScript, we can get pretty much any sequnce of tokens,
and we shouldn't crash if it's not something that we normally expect.
Instead, emit syntax errors.
In C++, it's invalid to cast a block of memory to a complex type without
invoking its constructor. It's even more invalid to simply cast a pointer to a
block of memory to a pointer to *an abstract type*.
To fix this, make sure FreelistEntry is a concrete type, and call its
constructor whenever appropriate.
This rewrite drastically increases the accuracy of object literals.
Additionally, an "assertIsSyntaxError" function has been added to
test-common.js to assist in testing syntax errors.
Since we're not keeping compatibility with OpenBSD about what promises are
required for which syscalls, tighten things up so that they make more sense.
This patch adds a context menu to variables in the debugger variable
tree view that has an option to set the value of a variable. An input
box will pop up asking for the new value of the variable, which
is then parsed and used to set the actual variable.
We were not setting the DMA transfer mode correctly. I have absolutely
no clue how this could ever have worked, but it did work for months
until it suddenly didn't.
Anyways, this fixes that. The sound is still a little bit glitchy and
that could probably be fixed by using the SB16's auto-initialized mode.
You can now request an update of the terminal's window progress by
sending this escape sequence:
<esc>]9;<value>;<max_value>;<escape><backslash>
I'm sure we can find many interesting uses for this! :^)
If a window in the taskbar has progress, we'll now draw that progress
in the form of a progress bar behind the window title on the taskbar
button for the window.
Each window now has an associated progress integer that can be updated
via the SetWindowProgress IPC call.
This can be used by clients to indicate the progress of ongoing tasks.
Any number in the range 0 through 100 indicate a progress percentage.
Any other number means "no progress"
