[question] assert is_consumer --> AssertionError --> ERROR:

[Peddaahh]

assert is_consumer --> AssertionError. Why does this happen and what does it do?

conan version

version: 2.0.17
python
  version: 3.10.11
  sys_version: 3.10.11 (tags/v3.10.11:7d4cc5a, Apr  5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)]

OS: Windows 11 x64 23H2

I am using conan for a another programminglanguage, where dependencies are compiled libraries equivalent to DLLs. So I wrote these two conanfiles to kind of wrap such a compiled library to a conanpackage to manage it via Artifactory. Analyzing the Package build folder, everyrthing should work fine. However there is an issue when deploying it via conan install. I have attached the two conanfiles and my used commands below. The .dll gets sucessfully deployed in the directory where the install conanfile is, within the subfolder libs,

but during the deploy() step, I get the following error:

PS C:\_work\repos\_conantest\testinstall> conan install . --deployer-package=*

Even after trying to understand what the code does where the error is happening, I could not fix the issue.

My conanfile which I execute with conan create .

from conan import ConanFile
from conan.tools.env import VirtualBuildEnv, VirtualRunEnv
from conan.tools.files import copy, download
from conan.tools.files.symlinks import absolute_to_relative_symlinks

class DLLBuild(ConanFile):
    name = "pkg"
    version = "0.1"

    def source(self):
        download(self,'http://localhost/pkg.dll', 'pkg.dll')

    def package(self):
        copy(self, "pkg.dll", src=self.source_folder, dst=self.package_folder)
        absolute_to_relative_symlinks(self, self.package_folder)

    def deploy(self):
        copy(self, "*.dll", src=self.package_folder, dst='lib')

The deploy conanfile which I execute with conan install . --deployer-package=*

from conan import ConanFile


class DLLDependencies(ConanFile):
    def requirements(self):
        self.requires("pkg/0.1")

Have you read the CONTRIBUTING guide?

Hi @Peddaahh

I am trying to reproduce, but this works:

def test_deploy_assert_error():
    c = TestClient()
    dep = textwrap.dedent("""
        from conan import ConanFile
        from conan.tools.files import copy, download
        from conan.tools.files.symlinks import absolute_to_relative_symlinks

        class DLLBuild(ConanFile):
            name = "pkg"
            version = "0.1"

            def source(self):
                pass # download(self,'http://localhost/pkg.dll', 'pkg.dll')

            def package(self):
                copy(self, "pkg.dll", src=self.source_folder, dst=self.package_folder)
                absolute_to_relative_symlinks(self, self.package_folder)

            def deploy(self):
                copy(self, "*.dll", src=self.package_folder, dst='lib')
            """)
    app = textwrap.dedent("""
        from conan import ConanFile

        class DLLDependencies(ConanFile):
            def requirements(self):
                self.requires("pkg/0.1")
                """)
    c.save({"dep/conanfile.py": dep,
            "app/conanfile.py": app})
    c.run("create dep")
    c.run("install app --deployer-package=*")

Checking the code, it seems that this has already been fixed in Conan 2.1. Can you please upgrade to Conan 2.1 and try again?
Thanks.

Oh, I see you are right.

This has been fixed in #15737, that belongs to 2.2, not to 2.1.

It will be released today, so I am closing this as solved in Conan 2.2, please update when it is out and let us know if the issue persist. Thanks!

[Peddaahh]

@memsharded can confirm, seems to be fixed and working fine now.

Thanks!
