Multiple statements with flags

[gsnedders]

I managed to accidentally have the following in a PR:

"safari": [
  {
    "version_added": "16"
  },
  {
    "version_added": "preview",
    "flags": [
      {
        "type": "preference",
        "name": "CSS overflow: clip support"
      }
    ]
  }
],

This is somewhat clearly nonsense.

Per our logic, preview > 16, and it doesn't make sense for it to be added in 16, and also added in a later version behind a flag without being removed from the earlier version.

This should also be raising an error due to the ordering, given preview > 16.

Actually, looking at what the linter does, the origin of this issue isn't really about preview at all, as the following is equally accepted, contrary to #16287:

"safari": [
  {
    "version_added": "16"
  },
  {
    "version_added": "17",
    "flags": [
      {
        "type": "preference",
        "name": "CSS overflow: clip support"
      }
    ]
  }
],

#17005 added a lint for this but decided to ignore flags, so your above statements still pass in BCD today. We can debate if that's a good choice or not.

If you remove d.flags from this condition:

browser-compat-data/test/linter/test-multiple-statements.ts

Line 29 in 35bbaad

if (d.partial_implementation || d.version_removed || d.flags) {

your above examples will fail. In existing data, you'll only get very few failures in the CI:

So, we could investigate if these 6 are non-sense or if they actually make sense.

And it looks like those ML entries are indeed wrong:

• api.MLGraphBuilder is behind a flag since 112 (that's fine ✅ ):
  

  browser-compat-data/api/MLGraphBuilder.json

  Lines 10 to 19 in 0bcc104

  	"chrome": {
  	"version_added": "112",
  	"flags": [
  	{
  	"name": "#web-machine-learning-neural-network",
  	"type": "preference",
  	"value_to_set": "Enabled"
  	}
  	]
  	},

• api.MLGraphBuilder.abs is behind a flag since 121 and since 126 (that's wrong ❌ that doesn't look right):
  

  browser-compat-data/api/MLGraphBuilder.json

  Lines 108 to 130 in 0bcc104

  	"chrome": [
  	{
  	"version_added": "126",
  	"flags": [
  	{
  	"name": "#web-machine-learning-neural-network",
  	"type": "preference",
  	"value_to_set": "Enabled"
  	}
  	],
  	"notes": "Supported on CPUs, GPUs and NPUs on macOS."
  	},
  	{
  	"version_added": "121",
  	"flags": [
  	{
  	"name": "#web-machine-learning-neural-network",
  	"type": "preference",
  	"value_to_set": "Enabled"
  	}
  	],
  	"notes": "Supported on GPUs and NPUs on Windows."
  	},

Edit: The approach in MLGraphBuilder was suggested in #22569 (comment), because we don't support OS and device type dimensions.

[caugner]

Looking at Firefox support for http.headers.Service-Worker-Navigation-Preload shows a valid use case for having multiple "open" statements:

browser-compat-data/http/headers/Service-Worker-Navigation-Preload.json

Lines 17 to 31 in 0bcc104

	"firefox": [
	{
	"version_added": "preview"
	},
	{
	"version_added": "97",
	"flags": [
	{
	"type": "preference",
	"name": "dom.serviceWorkers.navigationPreload.enabled",
	"value_to_set": "true"
	}
	]
	}
	],

I think we might want to update the linter to forbid multiple "open" statements of the same "dimension", e.g.:

// Valid
[
  {
    "version_added": "preview"
  },
  {
    "version_added": "97",
    "flags": [
      {
        "type": "preference",
        "name": "dom.serviceWorkers.navigationPreload.enabled",
        "value_to_set": "true"
      }
    ]
  }
]

// Invalid
[
  ,
  {
    "version_added": "100",
    "flags": [
      {
        "type": "preference",
        "name": "dom.serviceWorkers.navigationPreload.enabled",
        "value_to_set": "true"
      }
    ]
  },
  {
    "version_added": "97",
    "flags": [
      {
        "type": "preference",
        "name": "dom.serviceWorkers.navigationPreload.enabled",
        "value_to_set": "true"
      }
    ]
  }
]

Effectively, this would forbid the approach used for the ML features.

[Elchi3]

The ML statements use this to record different compat data for different operating systems or chips (NPU, GPU, CPU) as BCD doesn't offer any other way.

[caugner]

Checked all non-ML features:

• ✅ api.ScreenOrientation.lock (1. partial, 2. flag)
• ✅ css.types.basic-shape.shape (1. preview, 2. flag)
• ❌ css.types.gradient.[repeating-]{conic,linear,radial}-gradient.hue_interpolation_method (1. stable, 2. flag)
• ❌ css.types.gradient.[repeating-]{conic,linear,radial}-gradient.interpolation_color_space
• ✅ http.headers.Service-Worker-Navigation-Preload (1. preview, 2. flag)

[caugner]

The ML statements use this to record different compat data for different operating systems or chips (NPU, GPU, CPU) as BCD doesn't offer any other way.

For api.MLGraphBuilder.abs, how about a single statement with notes grouped by device ...

{
  "version_added": "116",
  "flags": [
    {
      "name": "#web-machine-learning-neural-network",
      "type": "preference",
      "value_to_set": "Enabled"
    }
  ],
  "notes": [
    "Supports GPUs and NPUs since Chrome 121 (Windows) and Chrome 126 (macOS)",
    "Supports CPUs since Chrome 116 (Windows, ChromeOS and Linux) and Chrome 126 (macOS)."
  ]
}

... or by OS ...

{
  "version_added": "116",
  "flags": [
    {
      "name": "#web-machine-learning-neural-network",
      "type": "preference",
      "value_to_set": "Enabled"
    }
  ],
  "notes": [
    "Supports Windows since Chrome 116 (CPUs) and Chrome 121 (GPUs, NPUs).",
    "Supports macOS since Chrome 126 (CPUs, GPUs, NPUs).",
    "Supports ChromeOS since Chrome 116 (only CPUs).",
    "Supports Linux since Chrome 116 (only CPUs).",
  ]
}

I would argue that this is more readable/comprehensible than having multiple statements.

[Elchi3]

Single statements with multiple notes would work for me, too. I forgot if https://webmachinelearning.github.io/webnn-status/ was generated by BCD data or if it was the other way around and @ibelem was generating BCD data from https://webmachinelearning.github.io/webnn-status/.

@ibelem do you have thoughts on the BCD data structure? Would @caugner's structure in the comment above work for you?
