Bug 52699 – Allow Fixed Length values to be floating point

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Simon Fraser (smfr)]

All Fixed Length values are currently truncated to ints. This is an issue for transforms, where the Length arguments to the various transform functions should really be floating point. Since we also interpolate through Lengths, this means that interpolated values are rounded to integers too.

Extends the Length class so it can store floating point values.

The Length class now stores 8 bits for floating point and 16 for integer. This changes loses the range of values that this class takes and gives a limited range for floating. Another way of fixing this would be to add a union, but this would increase the memory footprint.

In that case the patch needs to include new results for all the affected tests.

This changelog entry needs to mention the changes in Length behavior.

I don't think it's acceptable to change the max and min int values that Length can store. That might break websites (which do things like z-index: 999999999).

That doesn't work today either. Length can store at most 134217472 which is less than 999999999. The class also doesn't do bounds checking, so the larger value will overflow and become garbage.

It seems that making it a full int or float is the correct solution. Is it acceptable that the class takes up 4 more bytes?

Bounds checking should happen elsewhere (e.g. in CSSPrimitiveValue methods).

I don't know; we pass Lengths by value all over the place.

I wasn't thinking of stack space. Is that a concern?
It was more about heap space if a lot of length objects are stored.

I've reimplemented my changes and the browser seems to render content fine, but I can't get a clean layout test. I reverted all my changes and tests are still failing.

Do I need to do more than sync everything and get the fonts?

[Rik Cabanier]

My new implementation of length can store an int or float. 
It should behave the same for integer content.

[Rik Cabanier]

I think the falures are because I don't have the right fonts on my system.
I'll try to get them installed or start developing on my mac.

I would just make the Length always be a float and not have it be both.  Also the bitfield is completely useless now if you use the full 32 bits for the number (it's not saving you any space), so you can just turn those into bools.

Lots of style errors too.  You might want to flag for review just so you can see the style errors and fix them.

I was trying to minimize changes to the code. By having it behave differently only when the object is constructed with a float, we keep existing behavior.

My first attempt was to move to just float, but it actually changes the result of a large number of operations. It resulted in a lot of changes all over the code and numerous problems and differences in the layout tests.
Float also has less significant digits than int...

The bitfield is actually still necessary because part of the table logic multiplies by 128. If the value was maxint, it results in overflows which cause incorrect layout.

I will look at the style errors.

[Dave Hyatt]

You can just ditch rawValue also instead of keeping it.  It has no meaning if the value isn't being hacked.

[Dave Hyatt]

I guess the union is fine for now.  The engine's eventually going to move to floats, though, but if you want to keep ints in the underlying storage temporarily I suppose that's fine.

I removed the setRawValue calls. However, I didn't remove the getRawValue because parts of the code use this to extract percentage values in fixed notation.

http://trac.webkit.org/changeset/79784 might have broken GTK Linux 32-bit Debug

[Adam Roben (:aroben)]

This patch is causing assertion failures on Windows. See bug 55321.

[Adam Roben (:aroben)]

Since the assertion failures have been happening for many days now, and a fix is not imminent, we're rolling out the change. Bug 55386 tracks the rollout.

[Adam Roben (:aroben)]

Reopening since this change is getting rolled out.
