🐞 bug report

Affected Rule

py_{test,binary,library}

Is this a regression?

I'm not sure. I think things work differently between venvs_site_packages=yes and venvs_site_packages=no. I started seeing this issue when switching over to venvs_site_packages=yes.

Description

The "Using PyPI" section in rules_python-documentation says:

‘Extras’ dependencies
Any “extras” specified in the requirements lock file will be automatically added as transitive dependencies of the package. In the example above, you’d just put requirement("useful_dep") or @pypi//useful_dep.

After switching to using venvs_site_packages=yes, I see that the above is not the case for all packages. For example, consider the following simple requirements.in:

etils[eapp,epath]

and its compiled requirements.txt as follows:

Based on the documentation referred to above, I'd expect the following py_test target to run without problems:

Details
load("@rules_python//python:defs.bzl", "py_test")
py_test(
name="etils_test",
srcs= ["etils_test.py"],
deps= [
"@pypi//etils",

)

where etils_test.py is defined as:

frometilsimporteappfrometilsimportepatheapp.better_logging()

However, I get the following error:

          🐞 bug report
          Affected Rule
          py_{test,binary,library}
          Is this a regression?
          I'm not sure. I think things work differently between venvs_site_packages=yes and venvs_site_packages=no. I started seeing this issue when switching over to venvs_site_packages=yes.
          Description
          The "Using PyPI" section in rules_python-documentation says:
          ‘Extras’ dependencies
          
Any “extras” specified in the requirements lock file will be automatically added as transitive dependencies of the package. In the example above, you’d just put requirement("useful_dep") or @pypi//useful_dep.
          After switching to using venvs_site_packages=yes, I see that the above is not the case for all packages. For example, consider the following simple requirements.in:
          etils[eapp,epath]

          and its compiled requirements.txt as follows:

          Based on the documentation referred to above, I'd expect the following py_test target to run without problems:
          Details
          load("@rules_python//python:defs.bzl", "py_test")
py_test(

          where etils_test.py is defined as:
          frometilsimporteappfrometilsimportepatheapp.better_logging()
          However, I get the following error:

          To make this target work, I need to add several transitive dependency packages to the rule manually. The following target works:
          load("@rules_python//python:defs.bzl", "py_test")
py_test(
name="etils_test",
srcs= ["etils_test.py"],
deps= [
"@pypi//absl_py",
"@pypi//etils",
"@pypi//simple_parsing",
"@pypi//importlib_resources",
],
)
          Note how absl_py is clearly a transitive dependency of etils, as can be seen from the compiled requirements.txt. I wonder if I just misunderstand what the documentation means about extras. It's unclear what the useful_dep in the documentation example is because I don't see any reference to useful_dep "in the example above" in the documentation.

              load("@rules_python//python:defs.bzl", "py_test")
py_test(

              Note how absl_py is clearly a transitive dependency of etils, as can be seen from the compiled requirements.txt. I wonder if I just misunderstand what the documentation means about extras. It's unclear what the useful_dep in the documentation example is because I don't see any reference to useful_dep "in the example above" in the documentation.

                  🐞 bug report
                  Affected Rule
                  py_{test,binary,library}
                  Is this a regression?
                  I'm not sure. I think things work differently between venvs_site_packages=yes and venvs_site_packages=no. I started seeing this issue when switching over to venvs_site_packages=yes.
                  Description
                  The "Using PyPI" section in rules_python-documentation says:
                  ‘Extras’ dependencies
                  
Any “extras” specified in the requirements lock file will be automatically added as transitive dependencies of the package. In the example above, you’d just put requirement("useful_dep") or @pypi//useful_dep.
                  After switching to using venvs_site_packages=yes, I see that the above is not the case for all packages. For example, consider the following simple requirements.in:
                  etils[eapp,epath]

                  and its compiled requirements.txt as follows:

                      Affected Rule
                      py_{test,binary,library}
                      Is this a regression?
                      I'm not sure. I think things work differently between venvs_site_packages=yes and venvs_site_packages=no. I started seeing this issue when switching over to venvs_site_packages=yes.
                      Description
                      The "Using PyPI" section in rules_python-documentation says:
                      ‘Extras’ dependencies
                      
Any “extras” specified in the requirements lock file will be automatically added as transitive dependencies of the package. In the example above, you’d just put requirement("useful_dep") or @pypi//useful_dep.
                      After switching to using venvs_site_packages=yes, I see that the above is not the case for all packages. For example, consider the following simple requirements.in:
                      etils[eapp,epath]

                      and its compiled requirements.txt as follows:

                      Based on the documentation referred to above, I'd expect the following py_test target to run without problems:
                      Details
                      load("@rules_python//python:defs.bzl", "py_test")

                      However, I get the following error:

                      To make this target work, I need to add several transitive dependency packages to the rule manually. The following target works:
                      load("@rules_python//python:defs.bzl", "py_test")
py_test(
name="etils_test",
srcs= ["etils_test.py"],
deps= [
"@pypi//absl_py",
"@pypi//etils",
"@pypi//simple_parsing",
"@pypi//importlib_resources",
],
)
                      Note how absl_py is clearly a transitive dependency of etils, as can be seen from the compiled requirements.txt. I wonder if I just misunderstand what the documentation means about extras. It's unclear what the useful_dep in the documentation example is because I don't see any reference to useful_dep "in the example above" in the documentation.

                          To make this target work, I need to add several transitive dependency packages to the rule manually. The following target works:
                          load("@rules_python//python:defs.bzl", "py_test")
py_test(
name="etils_test",
srcs= ["etils_test.py"],
deps= [
"@pypi//absl_py",
"@pypi//etils",
"@pypi//simple_parsing",
"@pypi//importlib_resources",
],
)
                          Note how absl_py is clearly a transitive dependency of etils, as can be seen from the compiled requirements.txt. I wonder if I just misunderstand what the documentation means about extras. It's unclear what the useful_dep in the documentation example is because I don't see any reference to useful_dep "in the example above" in the documentation.

                              py_{test,binary,library}
                              Is this a regression?
                              I'm not sure. I think things work differently between venvs_site_packages=yes and venvs_site_packages=no. I started seeing this issue when switching over to venvs_site_packages=yes.
                              Description
                              The "Using PyPI" section in rules_python-documentation says:
                              ‘Extras’ dependencies
                              
Any “extras” specified in the requirements lock file will be automatically added as transitive dependencies of the package. In the example above, you’d just put requirement("useful_dep") or @pypi//useful_dep.
                              After switching to using venvs_site_packages=yes, I see that the above is not the case for all packages. For example, consider the following simple requirements.in:
                              etils[eapp,epath]

                              and its compiled requirements.txt as follows:

                              Note how absl_py is clearly a transitive dependency of etils, as can be seen from the compiled requirements.txt. I wonder if I just misunderstand what the documentation means about extras. It's unclear what the useful_dep in the documentation example is because I don't see any reference to useful_dep "in the example above" in the documentation.
