This changes the work we do for document.open() in the following ways:
- We no longer create a new Window when doing document.open().
We use the same Window but remove all the event listeners on the
existing DOM tree and Window before removing the document's existing
children to provide a clean slate document to use for .write().
- We no longer create a session history entry (previously would be a
wyciwyg URI). We now replace the current one, effectively losing the
entry for the original document.
- We now support document.open() on windowless documents.
list collisions when processing the background color of a table.
This is effectively #146 Part 3c to go along with the other 2 there.
This resolves#1308.
list items.
This patch does the following things:
1. Creates nsDisplayTableBorderCollapse that draws all collapse border
of tables.
2. Stops the use of nsDisplayTableBorderBackground.
3. Lets column and column group frames generate display items.
4. When traversing the table, also traverses the column and column group
frames.
5. For each type of table frame (col group, col, row group, row and
cell), draws their own background.
List of relevant patches applied:
1398537 part 2 - [css-multicol] Implement percentages for 'column-gap' (Gecko part).
1434478 part 1 - [css-grid] Stop back-computing percentage grid gaps when the percentage basis is indefinite. Treat them as zero sized instead.
1434478 part 2 - Stop back-computing percentage padding/margin when the percentage basis is indefinite. Treat them as zero sized instead.
1434478 part 3 - Remove IntrinsicISizeOffsetData::hPctPadding/hPctMargin members since they are now unused.
1434478 part 4 - Factor out constants like NS_UNCONSTRAINEDSIZE so they can be used in headers without needing nsIFrame.h (idempotent patch).
1434478 part 5 - Create nsLayoutUtils::ResolveToLength for resolving CSS <length-percentage> (idempotent patch).
1434478 part 6 - Propagate a percentage basis to nsIFrame::IntrinsicISizeOffsets for resolving padding/margin.
This is needed only for CSS Grid since in other cases we're only using IntrinsicISizeOffsets in the inline-axis and the percentage basis is always indefinite for *intrinsic sizing*. When calculating the intrinsic size of grid items in the grid container's block axis however, we do have a definite size for the grid area in the inline-axis and it should be used per: https://drafts.csswg.org/css-grid/#algo-overview "2. Next, the track sizing algorithm resolves the sizes of the grid rows, using the grid column sizes calculated in the previous step." (Percentage padding/margin for grid items is always resolved against the grid area's inline-size nowadays.)
Tag #1052 (backout).
Backed out for creating issues like #1191 and other issue-less problems
with e.g. losing the caret from text boxes. Of note: this was also
backed out from m-c for similar reasons in Bug 1332433.
This fixes#1191.
This reverts commit 3424afccaebc71c4acd4fa9eadf519c408c5965b.
UXP has:
MOZ_RELEASE_ASSERT(sAliveDisplayItemDatas && sAliveDisplayItemDatas >Contains(this));
sAliveDisplayItemDatas->RemoveEntry(this);
and this gets hit during frame destruction.
Combine these checks.
* Simplify the dispatch-to-content region
Simplify the dispatch-to-content region in nsDisplayLayerEventRegions::AddFrame() and AddInactiveScrollPort() if it starts to get large.
* tabs to spaces
This creates a number of stubs and leaves some surrounding code that may be irrelevant (eg. recorded time stamps, status variables).
Stub resolution/removal should be a follow-up to this.
nsTabSizes is non-trivial only because of the user-defined constructor. The idea desired here is certainly to zero all the members without listing them -- but the very act of doing so with a user-defined constructor, makes the idea impossible.
Arguably this is something that is permissible in the language, and that the warning should be tailored to permit. I don't think this falls afoul of any of the issues flagged in https://gcc.gnu.org/ml/gcc-patches/2017-06/msg01527.html for example. In the meantime, just explicitly zeroing the three member fields is easy and fixes the warnings.
