oelint.var.suggestedvar

severity: info

Example

In my-recipe_1.0.bb

A = "2"

Why is this bad?

A few variables are suggested to be added, as it adds more information what the recipe is about. In terms of CVE_PRODUCT it also helps to avoid false positives of the CVE check functionality.

Ways to fix it

The following variables are suggested to be added to each recipe

• AUTHOR
• BUGTRACKER
• BBCLASSEXTEND
• CVE_PRODUCT
• SECTION

AUTHOR = "me <me@mine.org>"
BUGTRACKER = "https://my-homepage/issues"
CVE_PRODUCT = "me/lib"
SECTION = "graphics"

BBCLASSEXTEND = "native"

Fine tuning

To fine tuned the behavior on the rule, you can apply the following constants

• oelint-suggestedvar/pkggroup-excludes to skip suggestedvar variables in a packagegroup
• oelint-suggestedvar/image-excludes to skip suggestedvar variables in images
• oelint-suggestedvar/{varname}-exclude-classes to skip {varname}, because of a class inherited that defines the variable already

e.g. if your custom class foo.bbclass contains

BUGTRACKER = "https://my-homepage/issues"
CVE_PRODUCT ?= "my/product"

but resides in a different layer than the current, you can run the linter with

oelint-adv --constantmods=+.my-custom-src-uri-classes.json <other options> <file>...

with .my-custom-src-uri-classes.json being

{
    "oelint-suggestedvar": {
        "BUGTRACKER-exclude-classes": [
            "foo"
        ],
        "CVE_PRODUCT-exclude-classes": [
            "foo"
        ]
    }
}

to let the linter know that this is fine in the given context.

See also the Configuration file option to automatically apply that to the layer.
