Questions about sub workspaces and query command

[Anna Ström]

Hi,

I have some questions about subworkspaces. First is a description of the environment and then the questions in the end.

Our environment

===============

Repo where we run the bazel commands from 

/bazel/...

Test repos added to bazel repo WORKSPACE file as follows:

local_repository(

    name = "world",

    path = "../../bbi/testarea/tutorialFromBazel/54322/Norden/World",

)

 

local_repository(

    name = "norden",

    path = "../../bbi/testarea/tutorialFromBazel/54322/Norden",

)

 

Our test repos

==============

Norden

├── BUILD

├── HelloNorden.cc

├── HelloNorden.hh

├── WORKSPACE

└── World

    ├── BUILD

    ├── HelloWorld.cc

    ├── HelloWorld.hh

    └── WORKSPACE

 

WORKSPACE File for Norden:

 

local_repository(

    name = "europe",

    path = "../Europe",

)

 

local_repository(

    name = "world",

    path = "World",

)

 

BUILD for Norden:

cc_binary(

    name = "HelloNorden",

    srcs = ["HelloNorden.cc", "HelloNorden.hh"],

    deps = ["@europe//:HelloEurope", "@world//:HelloWorld"],

    visibility = ["//visibility:public"],

)

WORKSPACE for World:

Empty

 

BUILD for World:

cc_library(

    name = "HelloWorld",

    srcs = ["HelloWorld.cc"],

    hdrs = ["HelloWorld.hh"],

    visibility = ["//visibility:public"],

   

)

======================================

 

Questions:

 

1. Is the structure of the test repos above with a subworkspaces like "World" valid?

2.

We run the following command standing in the bazel workspace

> bazel query 'attr(visibility, "//visibility:public", @norden//...)'

 

What is the correct result:

@norden//World:HelloWorld

@norden//:HelloNorden

 

or

 

@norden//:HelloNorden

 

3. Where does bazel search for valid packages when  using a label like @norden//...?

When I added traces it seems like  it searches in any directory in both bazel directory and in the test repos including following the cache and the available direcories there including external.
