Conan version ranges not working with loosely names packages.

To help us debug your issue please explain:

• I’ve read the CONTRIBUTING guide.
• I’ve specified the Conan version, operating system version and any tool that can be relevant.
• I’ve explained the steps to reproduce the error or the motivation/use case of the question/suggestion.

Conan Version 1.12.2 Distributor ID: Ubuntu Description: Ubuntu 16.04.5 LTS Release: 16.04 Codename: xenial

This is a workaround for: https://github.com/conan-io/conan/issues/4600, see latest comments

Conan version ranges don’t work as expected with include_prerelease=True I’m expecting it to be able to find my latest package, but it does not.

I have the following packages on artifactory: CastleConanCommon/0.0.3@master/latest CastleConanCommon/0.0.4-3-gff22b81@master/latest The 0.0.4 is now using git describe to uniquely version every commit.

a test conanfile with

class testConanfile(ConanFile):
    name = "testConanfile"
    version = "1.0.0"
    generators = "virtualenv"
    build_requires = "CastleConanCommon/[>=0.0.4, include_prerelease=True]@master/latest"

This results in the conan install . -u to fail

# conan install . -u 
Configuration:
[settings]
arch=x86_64
build_type=Debug
compiler=gcc
compiler.libcxx=libstdc++
compiler.version=5
os=Linux
[options]
[build_requires]
[env]

ERROR: Version range '>=0.0.4, include_prerelease=True' from requirement 'CastleConanCommon/[>=0.0.4, include_prerelease=True]@master/latest' required by 'virtual' could not be resolved

However, if I change the build_requires to build_requires = "CastleConanCommon/[>=0.0.3, include_prerelease=True]@master/latest" it works…

I’d expect that semver would recognized the first part 0.0.4-3-gff22b81 as 0.0.4 and be able to find the package.

@jgsogo here is the code I’m using to restructure the git tag to fit the node-semver if it’s useful for the documentation. We are using tags with vX.Y.Z pattern on our master branches. As mentioned, this was a workaround until the upcoming package revision feature is out (to enforce dependency tree rebuilds on every commit with full_package_mode). See https://github.com/conan-io/conan/issues/4600 for details.

def get_version_git_tag():
    try:
        git = tools.Git()
        gitTag = git.run("describe --tags --match 'v*.*.*' --long")
        gitTag = gitTag[1:]
        #we are renaming the package to fit prerelease versioning requirements
        gitTagRe = '([0-9]+\.[0-9]+\.[0-9]+)\-([0-9]+)\-([a-zA-Z0-9]+)'
        r = re.search(gitTagRe, gitTag)
        version = "%s-%s+%s" % (r.group(1), r.group(2), r.group(3))
        return version
    except:
        return None
