bazelbuild/bazel@6a8ddb7 changed the prefix for runfiles from the main
repo when Bzlmod is enabled. Because all uses of rlocation were
hardcoded to use "bazel_skylib", tests requiring runfiles stopped
working with Bzlmod enabled. This commit updates calls to rlocation to
instead use the TEST_WORKSPACE env var to get the repo name.
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.
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.
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.
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.
This should fix some buildkite CI flows, ensuring success of
this test is no longer tied to the current compilation_mode.
It also improves the error message of the offending evaluation.
* 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/
Specifically:
selects.config_setting_group(
name = "always_true",
match_any = ["//conditions:default"],
)
and
selects.config_setting_group(
name = "always_true",
match_all = ["//conditions:default"],
)
These should, as expected, always evaluate to True.
Their implementation had a bug that failed the build outright.
* 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

The output directories for the target under test may differ when the target is under a config transition (config_settings is passed to analysistest.make). Since analysis tests may assert about the command-line of generated actions, and those command-lines may contain paths to output files, this is useful information to expose.
* Add sets.is_set() to test whether an arbitrary object is a set.
Since using sets requires special API, it can be useful to determine
whether an object is a set so special handling can be used.
For example, if a method wants to be able to take a list or a set.
* Make sets.bzl point to new_sets.bzl instead of old_sets.bzl
new_sets.bzl and old_sets.bzl should be removed in the following skylib release.
Fixes #155.
* update and rename test suites
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.
* Fix a number of misc issues to allow google usage of bazel-skylib
1. Missing copyright header
2. Shell test fixes to use TEST_TMPDIR to have write access to directories
3. diff_test fix to use TEST_SRCDIR
* added a comment as to why diff_test_tests is local
* ran buildifier
This new test rule compares two files and passes
if the files match.
On Linux/macOS/non-Windows, the test compares
files using 'diff'.
On Windows, the test compares files using
'fc.exe'. This utility is available on all Windows
versions I tried (Windows 2008 Server, Windows
2016 Datacenter Core).
