Add dependencies to package output info when binary is not found (close #3316) by jgsogo · Pull Request #3438 · conan-io/conan

jgsogo · 2018-08-30T08:36:58Z

close Better information on mismatch in dependency tree #3316
I've read the Contributing guide.
I've followed the PEP8 style guides for Python code.
Add test

Current (1.7) ouput is:

Or read "http://docs.conan.io/en/latest/faq/troubleshooting.html#error-missing-prebuilt-package"

we can easily improve the output listing the dependencies:

Looks good, thanks. Please add a test for it.

+        self.client.save({"conanfile.py": dep1_conanfile.format(version="1.0")}, clean_first=True)


Instead of parameterizing the template, name and version, remove them and do conan create . PkgName/version@user/channel

Didn't realize that this was possible, lesson learned!

Don't extract it to the setUp(), unless it is clear common code shared by several tests in the fixture. Just put the preparation code in the test itself.

+        self.client.run("create . lasote/testing", ignore_error=True)


This is exactly the place you have to check the returned error from run()

ok, I check for the return value. I thought that checking for the text itself in the following lines would be enough, but no, you are right, it is important to check that the command has failed

+class FooPkg(ConanFile):
+    name = "foo"
+    version = "1.0"
+    requires = "dep1/{dep1_version}@lasote/testing", "dep2/1.0@lasote/testing"


why 2 dependencies? The test can be perfectly done with 1.

The issue we are testing is that dep2/1.0 (which depends on dep1/1.0) is not available when we bump dep1/1.0 to dep1/2.0 inside foo package.

It could be tested such output, even if the binary is missing for another reason, so not really necessary to have such complex dependency graph. But I agree, it is nicer to test the full case, just in case.

yes, you are right, we can remove dep1/1.0 from the repo and it should provide the same kind of information in the output message. It wouldn't fail for the same reason (override of transitive dependencies) but that behavior should have been tested at some other place.

I can leave here the minimum test and maybe create a new test module to store those tests that are 1-to-1 related to an specific issue.

No need to do 2 tests, I think this one is ok here, just with some improvements.

+        self.servers = {"myremote": test_server}


Finally, there is no upload, so you can remove the server.

Do not use self.client if client is possible

Name also unnecessary.

I know, but I prefer to keep the name in the recipe... at least to know but that conanfile.py is about. Is there any reason (internal to the machinery of Conan) to leave it out?

Fair enough, you can leave the name.

Unused imports. Try to enable a linter (like pep8, pycodestyle) in your IDE, it typically warns about unused imports (and unused variables, etc).

Also, try to follow the import order: first python ones, then dependencies, then conan imports.
