289b62732b Fix issue with alternating flex direction and percent postions (#1663)
Summary:
X-link: https://github.com/facebook/react-native/pull/44792

Pull Request resolved: https://github.com/facebook/yoga/pull/1663

Fixing https://github.com/facebook/yoga/issues/1658. We had a problem where if a child had a different flex direction than its parent, and it also set a position as a percent, it would look at the wrong axis to evaluate the percent. What was happening was we were passing in the container's mainAxis size and crossAxis size to use to evaluate the position size if it was a percent. However, we matched these sizes with the main/cross axis of the child - which is wrong if the flex direction is different.

I changed it so that the function just takes in ownerWidth and ownerHeight then calls isRow to determine which one to use for the main/cross axis position. This reduces the ambiguity quite a bit imo.

72b7e5b5cf Fix issue where % width would be wrong if physical and relative padding defined on parent (#1662)
Summary:
X-link: https://github.com/facebook/react-native/pull/44791

Pull Request resolved: https://github.com/facebook/yoga/pull/1662

This should fix https://github.com/facebook/yoga/issues/1657. Rather insidious bug but we had code like

```
  // The total padding/border for a given axis does not depend on the direction
  // so hardcoding LTR here to avoid piping direction to this function
  return node->style().computeInlineStartPaddingAndBorder(
             axis, Direction::LTR, widthSize) +
      node->style().computeInlineEndPaddingAndBorder(
          axis, Direction::LTR, widthSize);
```

That comment is NOT true if someone sets both the physical edge and relative edge. So like paddingLeft and paddingEnd for RTL. This diff simply pipes the direction to that spot to use instead of hardcoding LTR. Every file changed is just to pipe `direction`.

Pull Request resolved: https://github.com/facebook/yoga/pull/1641

Yoga has quirk where newly constructed nodes are clean, which isn't really correct. Normally never shows in in real code because setting a style or children  will dirty. Fabric doesn't use the public APIs that do this dirtying, so it ends up getting creative instead.

We should fix so that newly constructed nodes are dirty. Copy-constructed Nodes (also only a Fabric thing, will retain original dirty flag.

Summary:
X-link: https://github.com/facebook/react-native/pull/43752

Gentest tests started failing because Chrome changed behavior of overflowed align-content container. Spec says should fallback to "safe center", which is really just "start", instead of previous "center" behavior. This changes behavior accordingly.

There is one bit where I think we are doing the wrong thing wrt alignment of flex start vs start (which we don't support yet), but couldn't repro a failing chrome test.

28975a6053 Remove public APIs for YGNodePrint and YGConfigSetPrintTreeFlag (#1567)
Summary:

Pull Request resolved: https://github.com/facebook/yoga/pull/1567

We are planning on overhauling NodeToString to output JSON instead of HTML for the purposes of better benchmarking and capturing trees in JSON format to benchmark later. This gives us a bit of a headache as we have to revise several build files to ensure this new library works, ensure that it is only included in certain debug builds, and deal with the benchmark <-> internal cross boundary that arises as the benchmark code (which is a separate binary) tries to interact with it.

On top of it all this is really not used at all.

The plan is to rip out this functionality and just put it in a separate binary that one can include if they really want to debug. That means that it cannot exist in the public API, so I am removing it here.

Private internals come next

67154d47a3 Replace CompactValue with StyleValueHandle and StyleValuePool (#1534)
Summary:
X-link: https://github.com/facebook/react-native/pull/42131

Pull Request resolved: https://github.com/facebook/yoga/pull/1534

Now that the storage method is a hidden implementation detail, this changes the underlying data structure used to store styles, from `CompactValue` (a customized 32-bit float with tag bits), to `StyleValuePool`.

This new structure operates on 16-bit handles, and a shared small buffer. The vast majority of real-world values can be stored directly in the handle, but we allow arbitrary 32 bit (and soon 64-bit) values to be stored, where the handle then becomes an index into the styles buffer.

This results in a real-world memory usage win, while also letting us store the 64-bit values we are wanting to use for math function support (compared to doubling the storage requirements).

This does seem to make style reads slower, which due to their heavy frequency, does have a performance impact observable by synthetics. In an example laying out a tree of 10,000 nodes, we originally read from `StyleValuePool` 2.4 million times.

This originally resulted in a ~10% regression, but when combined with the changes in the last diff, most style reads become simple bitwise operations on the handle, and we are actually 14% faster than before.

8c3e01166b Remove row-reverse errata (#1547)
Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1547

X-link: https://github.com/facebook/react-native/pull/42251

Yoga has an odd behavior, where `start`/`end` edges under row-reverse are relative to flex-direction, instead of writing direction.

While Yoga doesn't actually document what this behavior is supposed to be, it goes against CK documentation, historic RN documentation, and the behavior valid on the web. It is also applied inconsistently (e.g. sometimes only on container, sometimes on child). It really is a bug, instead of an intended behavior.

We changed the default behavior for Yoga, but left the existing one behind an errata (so existing fbsource users got old behavior). We have previously seen this behavior show up in product code, including CK when running on FlexLayout.

`row-reverse` is surprisingly uncommon though:
1. Litho has <40 usages
2. RN has ~40 usages in `RKJSModules`,~30 in `arvr/js`, ~6 in `xplat/archon`
3. CK has ~80 usages
4. NT has ~40 usages

There are few enough, mostly simple components, that we can inspect through each of them, looking for signs they will hit the issue (at the potential chance of missing some).

CK accounts for 10/14 usages that I could tell would trigger the issue, since it only exposes start/end edge, and not left/right. It might make sense to make it preserve behavior instead, to reduce risk a bit.

FlexLayout is now separately powering Bloks, which wasn't surveyed, so I didn't touch CK behavior under Bloks.

There could also be other usages in other frameworks/bespoke usages, and this has implications for OSS users. But based on our own usage, of many, many components, this seems rare.

3b0545b15d Add tests for cycles with percentage dimensions (#1530)
Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1530

Yoga has a shortcut where if a min dimension and max dimension are the same, the value acts as a definite length.

I was curious how browsers handled this.

CSS 2.1 said:
> If the containing block's width depends on this element's width, then the resulting layout is undefined

This is superceded in the CSS box sizing spec. https://www.w3.org/TR/css-sizing-3/#sizing-values

> If, in a particular axis, the containing block’s size depends on the box’s size, see the relevant layout module for special rules on how to resolve percentages. Negative values are invalid.

And later:
https://www.w3.org/TR/css-sizing-3/#cyclic-percentage-contribution

> Sometimes the size of a percentage-sized box’s containing block depends on the intrinsic size contribution of the box itself, creating a cyclic dependency. When calculating the intrinsic size contribution of such a box (including any calculations for a content-based automatic minimum size), a percentage value that resolves against a size in the same axis as the intrinsic size contribution (a cyclic percentage size) is resolved specially:

> If the box is non-replaced, then the entire value of any max size property or preferred size property (width/max-width/height/max-height) specified as an expression containing a percentage (such as 10% or calc(10px + 0%)) that is cyclic is treated for the purpose of calculating the box’s intrinsic size contributions only as that property’s initial value. For example, given a box with width: calc(20px + 50%), its max-content contribution is calculated as if its width were auto. (The percentage is honored as usual, however, during the actual sizing of the box itself; see below.)

> Otherwise, the percentage is resolved against the containing block’s size. (The containing block’s size is not re-resolved based on the resulting size of the box; the contents might thus overflow or underflow the containing block).

So, for the purpose of sizing the parent, the child sized using a percentage does not contribute, but we should be sizing children based on that size.

Yoga does not really work like this right now, but gets the answer right answer for half of these tests.

192016a0a8 Make CompactValue internal detail of yoga::Style (#1492)
Summary:
X-link: https://github.com/facebook/react-native/pull/41776
Pull Request resolved: https://github.com/facebook/yoga/pull/1492

# Summary

In preparation to replace `CompactValue`, this fully encapsulates it as an implementation detail of `yoga::Style`.

The internal API now always operates on `Style::Length`, converted to `YGValue` at the public API boundary.

In the next step, we can plug in a new representation within `Style`, which should enable 64 bit values, and lower memory usage.

# Test Plan

1. Existing tests (inc for style, invalidation, CompactValue) pass
2. Check that constexpr `yoga::isinf()` produces same assembly under Clang as `std::isinf()`
3. Fabric Android builds
4. Yoga benchmark does style reads

# Performance

Checking whether a style is defined, then reading after, is a hot path, and we are doubling any space style lengths take in the stack (but not long-term on the node). After a naive move, on one system, the Yoga benchmark creating, laying out, and destroying a tree, ran about 8-10%  slower in the "Huge nested flex" example. We are converting in many more cases instead of doing undefined check, but operating on accessed style values no longer needs to do the conversion multiple times.

I changed the `CompactValue` conversion to YGValue/StyleLength path to check for undefined as the common case (since we always convert, instead of calling `isUndefined` directly on CompactValue. That seemed to get the difference down to ~5-6% when I was playing with it then. We can optimistically make some of this up with ValuePool giving better locality, and fix this more holistically if we reduce edge and value resolution.

On another machine where I tested this, the new revision went the opposite direction, and was about 5% faster, so this isn't really a cut and dry regression, but we see different characteristics than before.

a1751127ef Fix align-content of cross-stretched container (#1524)
Summary:
X-link: https://github.com/facebook/react-native/pull/41964

Pull Request resolved: https://github.com/facebook/yoga/pull/1524

D52087013 (#1513) fixed some issues, including where measuring under max-content or fit-content, align-content stretch would consume the entire available cross-dimensions, instead of only sizing to definite dimension, like the spec dicates.

I missed a case, where flexbox considers a container as having a definite cross-size if it is being stretched, even if it doesn't have a definite length.

https://www.w3.org/TR/css-flexbox-1/#definite-sizes

> 3. Once the cross size of a flex line has been determined, items in auto-sized flex containers are also considered definite for the purpose of layout;

> 1. If a single-line flex container has a definite cross size, the outer cross size of any stretched flex items is the flex container’s inner cross size (clamped to the flex item’s min and max cross size) and is considered definite.

We handle `align-items: stretch` of a flex container after cross-size determination by laying out the child under stretch-fit (previously YGMeasureModeExactly) constraint. This checks that case, and sizing the line container to specified cross-dim if we are told to stretch to it.

We could probably afford to merge this a bit with later with what is currently step 9, where we end up redoing some of this same math.

Fixes https://github.com/facebook/yoga/issues/1008

This fixes a smattering of issues related to both sizing and aligment of multi-line-containers:

1. We were previously incorrectly bounding the size of each flex line to the min/max of the entire container.
2. Per-line leads were sometimes incorrectly contributing to alignment within the line
3. The cross dim size used for multi-line alignment is not correct, or correctly clamped. If the available size comes from a max constraint, that was incorrectly used instead of a definite size, or size of content. Leads were entirely skipped for min constraint.

Need to test how breaking this is, to see if it might need to go behind an errata.

c93734f579 Fix issue in gentest where border-<edge> would add a border to test (#1496)
Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1496

Gentest code has a problem where we try to apply a border in our test when the web browser is not actually adding one. This happens when we do something like `border-top: 10px`. This will actually set the style of the border to `initial` which is just `none`, so nothing renders. This is causing at least 1 test to pass when it actually fails.

I changed it so we ignore setting this value if the style is one of these values. I then re-ran the gentest code and excluded the now failing test (which gets fixed in my static stack).

Pull Request resolved: https://github.com/facebook/yoga/pull/1454

One of the most basic aspects of statically positioned nodes is that [insets do not apply to them](https://developer.mozilla.org/en-US/docs/Web/CSS/position#static). So I put a guard inside `Node::relativePosition` where we take that into account when setting the position.

aca02406ef CompactValue -> Style::Length (#1458)
Summary:
X-link: https://github.com/facebook/react-native/pull/41392

Pull Request resolved: https://github.com/facebook/yoga/pull/1458

We're moving `CompactValue` to be an internal detail of `yoga::Style`, where users outside of the style will be dealing with a resolved/non-compact representation.

This change renames usages of `CompactValue` to `Style::Length`, which will be Yoga's representation for CSS input lengths. Right now one is just a type alias of the other, but this will let us change the internals of CompactValue with the rest of the world looking the same.

A few factory functions are added to `yoga::value` for creating CSS values. There are some shenanigans around how we want to represent CSS pixels (one YGUnitPoint), when we also end up adding CSS points (slightly larger than one YGUnitPoint). For now, I reused `point` until making other changes.

f2c8acad2c Allow lazy resolution of edge dimension values (#1453)
Summary:
X-link: https://github.com/facebook/react-native/pull/41347

Pull Request resolved: https://github.com/facebook/yoga/pull/1453

This follows the previous patterns used for `Gutters` and `Dimension`, where we hide CompactValue array implementation from `yoga::Style` callers.

This allows a single read of a style to only need access to the resolved values of a single edge, vs all edges. This is cheap now because the interface is the representation, but gets expensive if `StyleValuePool` is the actual implementation.

This prevents us from needing to resolve nine dimensions, in order to read a single value like `marginLeft`. Doing this, in the new style, also lets us remove `IdxRef` from the API.

We unroll the structure dependent parts in the props parsing code, for something more verbose, but also a bit clearer.

283e3203f6 Fix issue where absolute children of row-reverse containers would inset on the wrong side (#1446)
Summary:
X-link: https://github.com/facebook/react-native/pull/41293

Pull Request resolved: https://github.com/facebook/yoga/pull/1446

NickGerleman pointed out that my recent changes to fix the slew of row-reverse problems in Yoga actually ended up regressing some parts. Specifically, absolute children of row-reverse containers would have their insets set to the wrong side. So if you set left: 10 it would apply it to the right.

Turns out, in `layoutAbsoluteChild` there were cases where we were applying inlineStart/End values to the flexStart/End edge, which can never be right. So I changed the values to also be flexStart/End as the fix here.

484118c89b Change gentest to only write position relative to parent
Summary:
`child.offsetLeft/Top` calculates the offset from child to its nearest positioned ancestor, not its direct parent. These are often the same and have not mattered in the past since we have not supported position static. Since are are in the process of supporting that, we would like our tests to be usable so this adjusts the gentest methodology to only speak the same language as Yoga - that is left/top are always relative to direct parents.

It works by using `getBoundingClientRect().left/top` instead. Then we pass that down to children and subtract it from the childs `getBoundingClientRect()` to get the position relative to the parent. Note we have to round the final result as `child.offsetLeft/Top` is rounded.

6cc9e58246 Add more tests to eventually test position: static
Summary:
Doing some test-driven-development to support this feature, so I will start by adding a ton of tests to ensure the nuance of position: static is captured in Yoga. Specifically I have a slew of tests to capture:

* Insets have no effect on static elements
* Insets are relative to the nearest non-static ancestor
* Percentage values for insets, padding, and margin of absolute children respect the correct dimension of the nearest non-static ancestor
  * Also added similar ones for static and relative children which should just respect their ancestor (static only because it is a flexbox by default)
  * This rule does NOT apply to border
* The containing block for absolute children is the padding box of their nearest non-static ancestor
* The containing block for static children is the content box of their parent (because all elements are flex containers in yoga, at least right now)

2ea4c043fd gentest support for position: static + initial test
Summary:
I am about to embark on supporting `position: static` in Yoga. The enum exists already (and is the default position type, lol) but does not actually do anything and just behaves like `position: relative`.

My approach here is to write a bunch of tests to test for the various behaviors of static positions and then develop on Yoga afterwards to get those tests passing. To do this, we need to make a few changes to the gentest files as there is not support for adding `position: static` at the moment:

* Make it so that the gentest code can physically write `YGPositionTypeStatic` if it encounters `position: static` in the style
* Make it so that gentest.js knows that Yoga's default is actually static. This way the code generated in the tests will actually label nodes for non default values
* Explicitly label the position type even when it is not declared in the style prop (with the exception of the default)
* Regenerate all the tests

Additionally I added the first, basic test: making sure insets do nothing on a statically positioned element.

2668e8e70c Fix row-reverse flex direction fixtures
Summary:
These tests were a bit weird for testing something with position. The gentest setup makes it so that the fixtures are wrapped in a absolutely positioned container with height and width bot 0. However, the generated yoga tests do NOT do this and instead have the root node as the fixture itself with no wrapping container.

This causes a problem when testing left/right/top/bottom position insets. Because left/right/top/bottom will position the element relative to its containing block when position is absolute, we will get different values on yoga and chrome even if the implementation is correct: https://developer.mozilla.org/en-US/docs/Web/CSS/right#description

To fix this, we just wrap the fixture in a set size div that is also absolutely positioned.

The file was also formatted.
