How do I list the root rules?

[oharboe]

In a github CI action, I want to check that everything builds, so I started by adding a bazelisk build ..., but this downloads all artifacts for all rules from our configured remote cache even when all builds are successful and there is nothing to do.

After thinking about it, I realized that in CI I don't want to build, I want to verify that everything builds. I can do this by building only the root rules in the dependency tree.

But how do I enumerate all the root rules that do not have the tags=["manual"] set?

I have come up with an incantation that does seem to do the trick, but it is a bit of an eyesore...

bazelisk query 'kind(rule, deps(kind(rule, //...))) except kind(test, //...) except attr(tags, manual, ...)' --output=maxrank | grep "^0 " | cut -f 2 -d' ' | grep -v "^@"

I have a simular situation with bazelisk test ..., it downloads artifacts that are not needed for targets that have tags=["manual"] set, so I replaced bazelisk test ... with:

bazelisk test $(bazelisk query 'kind(test, ...) except attr(tags, manual, ...)')

Have you tried building with `--remote_download_minimal` to avoid downloading remote artifacts into the output tree?

This seems to work, avoids lots of downloads:

bazel build --remote_download_minimal ...

However, for testing lots of artifacts that are not needed (the root tests pass) are still downloaded and built:

bazel test --remote_download_minimal ...

However, that could be an unrelated problem where tags=["manual"] are not respected unless I manually prune the tests:

bazelisk test --remote_download_minimal $(bazelisk query 'kind(test, ...) except attr(tags, manual, ...)')
