[question] conan2 local integrity check of cache contents based on manifest

[bbandix]

What is your question?

Hi!

We started an experimental migration of our packages to conan 2.x.

In our integration with conan 1.x we used the following to check the integrity of packages in the local cache based on the manifest:

conan upload --skip-upload --all -c '*'

In conan 2.x --skip-upload is gone, thus the above does not seem to be possible any more.

Question:

• Is a local integrity check based on the manifest possible in some other way or is the recommended way to implement a custom command for this?
• Perhaps a conan cache check PATTERN sub-command to conan cache would be the right place for such a feature

Have you read the CONTRIBUTING guide?

• I've read the CONTRIBUTING guide

Hi @bbandix

It is true that Conan 2.0 removed this "skip-upload" case that can be leveraged for checking packages checksums.
I think we might want to introduce this check, probably as a conan cache subcommand, labeling this as a possible feature.

In the meantime, it should be relatively easy to create your own custom command to do that, because the api exposes it, something like this could be enough:

    ref_pattern = ListPattern(args.reference, package_id="*", only_recipe=args.only_recipe)
    package_list = conan_api.list.select(ref_pattern, package_query=args.package_query)
    conan_api.cache.check_integrity(package_list)

The https://docs.conan.io/2/examples/extensions/commands/clean/custom_command_clean_revisions.html docs might help.

Hi @memsharded,
Thanks again for the quick answer!

[memsharded]

As this is quite straightforward, I am directly proposing it for built-in in #13502, lets see how it goes.

#13502 was merged, conan cache check-integrity will be in 2.0.3
