I ran into an issue where I had a `build_test` that was only compatible with a particular platform. I had annotated the target with `target_compatible_with` but continued to get builds on the incompatible platform. This came down to my `bazel test //...` invocation picking up the `{name}_{idx}__deps` targets and building the dependency anyway. This change updates these targets to account for newer common attributes and tags them as manual so they're only built when the user facing test target is built.
After some thought, I have to say that forcing a local strategy for
copy_file/copy_directory is inappropriate. The point of a sandbox is to
catch hermeticity bugs; disabling the sandbox may be useful for
performance, but it's up to the user to do it if they trust us - and
they can do it via flag. The default should be paranoia and safety.
And on the subject of strategies - using a genrule to create an empty
directory fails in environments where genrules run remote by default
(and thus, copy_directory tests fail). We could, of course, set local=1,
but that disables the sandbox and causes scary warnings. Instead, add a
proper empty_directory rule to test with.
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.
* copy_file: Add parameter to allow symlinks
This change adds a new parameter `allow_symlinks` to `copy_file` that
allows the action to create a symlink instead of doing an expensive
copy if the execution platform (host) allows it.
Updates #248
* Update docs
* Refactor `is_executable` into attribute
* Fix typo
* s/_impl/_copy_file_impl/
* Create a helper rule for selecting a file from outputs of another rule or a filegroup by subpath
* Add tests
* Address code review comments
* + formatting

* make the tarball 555
* Split the bins out from the rest of the package and combine the
packages.
This solution is horrible. The better solution is
- We need something like pkgfilegroup in rules_pkg, so we can specify
exectuable mode next to the file.
- But we do not want rules_pkg to appear in the rules/BUILD file
because that would make a runtime dependency.
So we need to
- rewrite rules/BUILD when going into the package.
- or provide magic mapping of files names to mode bits
- or something entirely different.
* add empty CHANGELOG.md to try to reuse bazel release.sh
* checkpoint a new distribution method
* Update CHANGELOG.
* checkpoint relnew
* get the tarball working
* fix visibilyt
* whitespace
* punctuation typos
* buildify
* linty fresh
This rule is an alternative for genrule(): it can
run a binary with the desired arguments,
environment, inputs, and outputs, as a single
build action, without shelling out to Bash.

native_binary() wraps a pre-built binary or script
in a *_binary rule interface. Rules like genrule
can tool-depend on it, and it can be executed with
"bazel run". This rule can also augment the binary
with runfiles.
native_test() is similar, but creates a testable
rule instead of a binary rule.
Fixes https://github.com/bazelbuild/bazel-skylib/issues/148
RELNOTES[NEW]: The new `native_binary()` and `native_test()` rules let you wrap a pre-built binary in a binary and test rule respectively.
The user can specify which line endings they want
write_file to use. This helps avoiding line ending
mismatches with diff_test.
Example: diff_test verifies that a rule generates
correct output by comparing it to a checked-in
"golden" file. Both files are text files, and the
user builds on Windows but the golden file was
written on Linux and git checkout preserved
original line endings.
Without explicitly specifying which line endings
to use, this diff_test would fail on an otherwise
good output.
With explicit line endings we don't need to check
in the golden file to git, we can just generate it
with "auto" line endings.
