A `url` can be very large, in particular if it is a data: url, so using it as a key for lookups whenever we load a few bytes is not a very good idea. This patch introduces an intermediate `LoadKey` (internally, an u64) that makes hashmap lookups faster. Somewhere along the way, we also get rid of a few calls to `url.clone()`.
Reasons behind existing unstable features:
std_misc:
- `Handle` usage (API will be replaced and is perhaps broken)
path_ext:
- Checking if a file exists. This is doable from the File directly, but slightly longer
core:
- `FnBox`
alloc:
- `boxed::into_raw()` (naming)
image fragments.
This also changes the way the placeholder is handled in the image cache
task to decode it up front instead of each time an image fails to load,
both because it was more convenient to implement that way and because
it saves CPU cycles to do so.
This matches the behavior of Gecko and WebKit. It improves the look of
our cached copy of Wikipedia.
* Simpler image cache API for clients to use.
* Significantly fewer threads.
* One thread for image cache task (multiplexes commands, decoder threads and async resource requests).
* 4 threads for decoder worker tasks.
* Removed ReflowEvent hacks in script and layout tasks.
* Image elements pass a Trusted<T> to image cache, which is used to dirty nodes via script task. Previous use of Untrusted addresses was unsafe.
* Image requests such as background-image on layout / paint threads trigger repaint only rather than full reflow.
* Add reflow batching for when multiple images load quickly.
* Reduces the number of paints loading wikipedia from ~95 to ~35.
* Reasonably simple to add proper prefetch support in a follow up PR.
* Async loaded images always construct Image fragments now, instead of generic.
* Image fragments support the image not being present.
* Simpler implementation of synchronous image loading for reftests.
* Removed image holder.
* image.onload support.
* image NaturalWidth and NaturalHeight support.
* Updated WPT expectations.
I decided to use the old Netscape broken image link icon (later we may
replace the image asset for something more trendier). The ref test will
expect that a failed load should display the rippy image.
ImageCacheTask users can define if a placeholder image should be loaded
at start up or not. This enables both the new behavior (e.g. always
return an image even for broken urls) as also the previous one.
- Most of util::memory has been moved into profile::mem, though the
`SizeOf` trait and related things remain in util::memory. The
`SystemMemoryReporter` code is now in a submodule
profile::mem::system_reporter.
- util::time has been moved entirely into profile::time.
This used to conflict with the util crate from the standard library, which
has long since been removed.
The import in layout has not been changed because of a conflict with the
util mod there.
- Added TargetedLoadResponse and ResponseSenders
- LoadData constructor contains the next consumer which means
SnifferManager doesn't need the next consumer to start
- New SnifferTask is created at new resource_task creation
- Update Unit Tests
