Incomplete stacktrace in `bazel mod show_repo`

laurentlb commented 1 month ago

Description of the bug:

The command bazel mod show_repo includes a stacktrace at the end of the output. In most cases, it just says <builtin> in <toplevel>, which doesn't give any information. I'd expect for example to get the line of bazel_dep in a MODULE.bazel file.

Example:

$ bazel mod show_repo rules_cc@0.0.9
## rules_cc@0.0.9:
# <builtin>
http_archive(
  name = "rules_cc~",
  urls = ["https://github.com/bazelbuild/rules_cc/releases/download/0.0.9/rules_cc-0.0.9.tar.gz"],
  integrity = "sha256-IDeHW5pEVtzkp50RKorohbvEqtlo5lh9ym5k86CQDN8=",
  strip_prefix = "rules_cc-0.0.9",
  remote_file_urls = {},
  remote_file_integrity = {},
  remote_patches = {"https://bcr.bazel.build/modules/rules_cc/0.0.9/patches/module_dot_bazel_version.patch": "sha256-mM+qzOI0SgAdaJBlWOSMwMPKpaA9b7R37Hj/tp5bb4g="},
  remote_patch_strip = 0,
)

We are actually not sure about what information should be shown, feel free to make a suggestion!

I guess it would be useful to print information to find where it comes from (e.g. lines in the MODULE file). I don't know if this information is available anywhere else.

But the same module could be referenced in different MODULE.bazel file. If you want to know, why a specific version of the module is selected, you can try bazel mod graph?
