[bug] Requires ranges with version X.Y.Z.A sometimes can't be found in remote

Environment Details (include every applicable attribute)

• Operating System+version: Windows Server 2019
• Compiler+version: N/A
• Conan version: 1.41.0
• Python version: 3.8.2

Steps to reproduce

Some packages in our remote have versions of the form X.Y.Z.A (usually for third-party packages to which we’ve done small changes to so we know what was the base version and the A is versions of our changes). However, sometimes it seems like Conan can’t find the package when using ranges of the form [>=X.Y.Z] during the conan lock create command.

Logs (Executed commands with output)

conanfile.py in the test_conan directory:

from conans import ConanFile

class TestConan(ConanFile):
    name = "test-conan"

    def requirements(self):

        self.requires('aws-sdk-cpp/[>=1.6.53]@PORT/stable')
        self.requires('avro-cpp/[>=1.10.2]@PORT/stable')

Conan searches on the remote:

E:\alefebvr\test_conan>conan search aws-sdk-cpp -r bb-conan-buildall-stable
Existing package recipes:

aws-sdk-cpp/1.6.53.7@PORT/stable

E:\alefebvr\test_conan>conan search avro-cpp -r bb-conan-buildall-stable
Existing package recipes:

avro-cpp/1.9.1.9@PORT/stable
avro-cpp/1.9.1.10@PORT/stable
avro-cpp/1.10.2.0@PORT/stable

When running conan lock create command:

E:\alefebvr\test_conan>conan lock create ./conanfile.py --version 12345 --user PORT --channel stable --build=missing --lockfile-out=base_recipe_information_only.lock --base

ERROR: Version range '>=1.6.53' from requirement 'aws-sdk-cpp/[>=1.6.53]@PORT/stable' required by 'conanfile.py (test-conan/12345@PORT/stable)' could not be resolved in remote 'bb-conan-buildall-stable'

After commenting the line with self.requires('aws-sdk-cpp/[>=1.6.53]@PORT/stable') in the conanfile.py, rerunning the above command:

E:\alefebvr\test_conan>conan lock create ./conanfile.py --version 12345 --user PORT --channel stable --build=missing --lockfile-out=base_recipe_information_only.lock --base
[...]

Thank you @memsharded for the quick answer! Any idea why sometimes it works and sometimes it doesn’t?

Yes, the 4th digit is basically ignored. There could be some randomness in the data structures ordering associated to order of creation, upload, or just luck that makes it work some times.

We have taken ownership of version-ranges and implemented our own solution, covering more than 3 canonical major.minor.patch. This is solved and released in 2.0-alpha, please try it when possible and report if necessary.
