From c6b39ab8f67f2c120d99c95fe4bb604c0b805348 Mon Sep 17 00:00:00 2001 From: Douglas Parker Date: Tue, 10 Oct 2023 07:16:13 -0700 Subject: [PATCH] fix: always include files from the same workspace as the build target in `copy_to_directory()` (#360) * fix: always include files from the same workspace as the build target in `copy_to_directory` Fixes #359. This updates the `copy_to_directory` tool to accept a workspace name representing the workspace of the target it is executing under. Any files in this workspace are automatically included, regardless of the `include_external_repositories` option. This makes it support usage within an external target (such as `@wksp//:dir`). * test: add e2e test which uses `copy_to_directory` within an external workspace Refs #359. This should catch regressions where no files are copied when built within an external workspace and not using `include_external_repositories`. * ci: fix stray workspace refs --------- Co-authored-by: Alex Eagle --- .aspect/workflows/config.yaml | 1 + .github/workflows/ci.yaml | 1 + docs/copy_to_directory.md | 2 +- e2e/external_copy_to_directory/.bazelignore | 1 + e2e/external_copy_to_directory/.bazelrc | 0 e2e/external_copy_to_directory/.bazelversion | 1 + e2e/external_copy_to_directory/BUILD.bazel | 13 +++++++ e2e/external_copy_to_directory/WORKSPACE | 28 +++++++++++++++ e2e/external_copy_to_directory/app/.bazelrc | 0 .../app/.bazelversion | 1 + .../app/BUILD.bazel | 6 ++++ e2e/external_copy_to_directory/app/WORKSPACE | 31 ++++++++++++++++ e2e/external_copy_to_directory/app/test.sh | 19 ++++++++++ e2e/external_copy_to_directory/directory.bzl | 36 +++++++++++++++++++ e2e/external_copy_to_directory/foo.txt | 1 + lib/private/copy_to_directory.bzl | 4 +-- 16 files changed, 142 insertions(+), 3 deletions(-) create mode 100644 e2e/external_copy_to_directory/.bazelignore create mode 100644 e2e/external_copy_to_directory/.bazelrc create mode 120000 e2e/external_copy_to_directory/.bazelversion create mode 100644 e2e/external_copy_to_directory/BUILD.bazel create mode 100644 e2e/external_copy_to_directory/WORKSPACE create mode 100644 e2e/external_copy_to_directory/app/.bazelrc create mode 120000 e2e/external_copy_to_directory/app/.bazelversion create mode 100644 e2e/external_copy_to_directory/app/BUILD.bazel create mode 100644 e2e/external_copy_to_directory/app/WORKSPACE create mode 100755 e2e/external_copy_to_directory/app/test.sh create mode 100644 e2e/external_copy_to_directory/directory.bzl create mode 100644 e2e/external_copy_to_directory/foo.txt diff --git a/.aspect/workflows/config.yaml b/.aspect/workflows/config.yaml index fb625a2..2afdc53 100644 --- a/.aspect/workflows/config.yaml +++ b/.aspect/workflows/config.yaml @@ -7,6 +7,7 @@ workspaces: - e2e/smoke - e2e/coreutils - e2e/copy_to_directory + - e2e/external_copy_to_directory bazel: flags: - --remote_download_minimal diff --git a/.github/workflows/ci.yaml b/.github/workflows/ci.yaml index a3ad141..d8f76c5 100644 --- a/.github/workflows/ci.yaml +++ b/.github/workflows/ci.yaml @@ -90,6 +90,7 @@ jobs: - "." - "e2e/coreutils" - "e2e/copy_to_directory" + - "e2e/external_copy_to_directory" - "e2e/smoke" exclude: # Don't test Bazel 5.3 with bzlmod.

Creating hardlinks is much faster than making copies of files with the caveat that hardlinks share file permissions with their source.
