copy_file currently includes the copied file in its runfiles even if it is not executable, which makes every rule depending on it have the file as a runfile (e.g. a `cc_library` depending on a copied header file via the hdrs attribute).
In an ideal world, according to https://docs.bazel.build/versions/main/skylark/rules.html#runfiles-features-to-avoid, `copy_file` would not need to specify any runfiles in the `DefaultInfo` it returns - specifying `files` should suffice. However, due to the existence of rules with legacy behavior, this would break compatibility (actually, already with `sh_test` in skylib's unit tests).
As a compromise that preserves compatibility with legacy rules but nevertheless cleans up the runfiles tree of depending rules, use the `data_runfiles` attribute of `DefaultInfo` if the copied file is not executable.
Followup to #330: remove the wrapper macro and export the rule directly; the macro
does not serve any useful function. As a side effect, this fixes the inability to
set tags etc., since the macro did not support **kwargs.
This attribute is incorrectly being built in the host configuration when
(like any test) it will run in the target configuration. This means that
cross compilation will be broken and options that differ between host
and target (e.g. `NDEBUG`) will not be as set by the user.
I confirmed that without this fix, a test binary with `assert(false)`
passes when run under `native_test`.
Additionally, the use of `allow_single_file` precludes rules that return
multiple files in their DefaultInfo (like `py_binary`). Instead, we can
use `allow_files` and access via `ctx.executable`.
The current implementation misses the runfiles from the binary itself
since the attribute for it is called `src` not `srcs` and it makes use
of the discouraged `collect_data` and `collect_default` parameters which
depend on hardcoded attribute names.
I find it more ergonomic to add notes or a description about a test to a `doc` attribute, similar to other rules, vs a comment block above it or in the `impl` function docstring. Hopefully this can improve the readability of test rules.
This is a relatively simple addition to unittest that statically creates rules
that either explicitly fail or not depending on if the test case is valid during
LOADING phase of bazel. The test conditions are evaluated entirely in loading
phase, but if we want an actual test to fail rather than just `fail()` killing
the build, we can use this to assert state and report test failures.

In particular, this allows us to use a modern Stardoc release to fix generated md docs.
And we can remove internal_deps.bzl/internal_setup.bzl - it's unnecessary complexity
needed only for deprecated Federation setup.
Due to grep having dropped support for handling line-ending matches in a cross-platform way, grepping for `...$` will now fail on Windows, as it no longer ignores the CR part of the CRLF line endings on Windows.
This should turn this project green again on Bazel CI.
* Enable unittest.suite to accept partial calls of rules
This permits using `unittest.suite` with test rules that have nondefault
attributes, while retaining compatibility with current usage.
For instance, this permits setting a `timeout` on each test in a
`unittest.suite`. Previously, all tests in a `unittest.suite` would
have the default timeout, with no good way to alter this. This
made it hard to eliminate all the warnings produced from using the
`--test_verbose_timeout_warnings` bazel option.
While timeouts were the motivation, the solution here is not specific
to timeouts. It will permit arbitrary additional arguments to the test
rules in a `unittest.suite`.
Fixes #98
* Respond to review feedback.
* Document a breaking change in bazel that this code needs to be aware of.
`@bazel_tools` is tricky since it is effectively a part of the standard
library that can not have a `bzl_library` attached to it. As a simple
fix for this, `bzl_library` can have a srcs dependency on it so that it
includes the transitive closure of all of its dependencies.
`@bazel_tools` imports are rewritten into the `srcs` attribute since
they are `exports_files`ed from the @bazel_tools.
