Based on [ebalint](https://github.com/ebalint)'s original patch, this commit implements the linear and radial gradients for the canvas. The PR also includes test cases.
Depends on #4623 and servo/rust-azure#136.
This fixes a bug in finding the top left corner of an RTL block in physical
coordinates. (The old code used the `start` point of the `position` rect,
which is not always the top left.)
It also fixes the setting of `position.start.i` in certain mixed LTR/RTL
cases.
There is still a bug related to `position.size` for RTL blocks with margins.
See the FIXME comments for details.
Implements view-source protocol by having a view-source handler, and modifying the content type to be text/plain if that is used.
Implements text/plain handling. This allows view-source content to display as plain text.
Example usage:
./mach run http://cd.pn/x.txt
./mach run view-source:http://tinyvid.tv/
This fixes issue #4181. Issue #3649 includes "support text/plain" so this possibly fixes some of that issue as well.
If the root layer has a zero size rectangle, it will never be
painted, so assume the pipeline is idle in that case.
Re-enable two reftests that were disabled due to this issue.
@jdm This initial version has a few outstanding issues that I wanted to invite input on. Specifically:
1. I had some difficulty finding a home for the `StorageType` enum. Structs defined outside of the `script` module don't seem to be able to use the `#[jstraceable]` annotation and the `net` module (where `StorageTask` lives) doesn't have access to `script`. Per Simon Sapin's suggestion, I worked around this temporarily by creating a `TraceableStorageType` stand-in struct that was traceable and which could be translated into a regular `StorageType` when being sent to the `StorageTask`. Unsure of the best way to resolve this hack. Thoughts?
2. Apart from the `Storage` constructor used in `Window::SessionStorage` and the new `Window::LocalStorage`, there's also a method called `Storage::Constructor`. I'm unclear on what (if anything) will actually invoke this, so I'm not sure which variant of `StorageType` to use here. I've temporarily created an `Unknown` variant of `StorageType` as a placeholder.
3. I discovered that the web platform tests directory's localStorage tests. Many of them now pass despite the configured expectation that they fail. However, several do not pass. Is there a good way for me to add debug logging or otherwise get a sense of which assertion failed / what went wrong?
Thanks for your continued help!
`./mach test tests/wpt/web-platform-tests/html/browsers/history/the-location-interface/security_location_0.sub.htm` is still failing with the same message as reported in #3219.
Table layout code has been refactored to push the spacing down to
rowgroups and rows; this will aid the implementation of
`border-collapse` as well.
r? @SimonSapin
`cellspacing` attribute per HTML5 § 14.3.9.
Table layout code has been refactored to push the spacing down to
rowgroups and rows; this will aid the implementation of
`border-collapse` as well.
This commit also fixes two nasty issues in table layout:
* In fixed layout, extra space would not be divided among columns that
had auto width but had nonzero minimum width.
* In automatic layout, extra space would be distributed to constrained
columns as well even if unconstrained columns with percentage equal to
zero were present.
This patch enables the use of `arc()` on the canvas.
I couldn't add reftest this time, as it involves some antialiasing issues, and so the reference doesn't match.
§ 12.3-12.5.
Only simple alphabetic and numeric counter styles are supported. (This
is most of them though.)
Although this PR adds a sequential pass to layout, I verified that on
pages that contain a reasonable number of ordered lists (Reddit
`/r/rust`), the time spent in generated content resolution is dwarfed by
the time spent in the parallelizable parts of layout. So I don't expect
this to negatively affect our parallelism expect perhaps in pathological
cases.
...and vice-versa. This is not a complete fix for all mixed-direction layout
cases, but it fixes enough problems to make some simple test cases pass, like
tha attached reftest.
There are FIXME comments for many of the remaining issues. In particular,
this does not yet handle RTL layout of fixed/absolute elements.
A race condition exists where pipelines that are removed from a document
may not ever trigger a paint for that pipeline. The compositor relies
on a paint occurring for each pipeline before outputting the image when
in reftest mode.
