[PR] MWAR-471: normalize file permissions on dependencies copied to WEB-INF/lib [maven-war-plugin]
elharo opened a new pull request, #634:
URL: https://github.com/apache/maven-war-plugin/pull/634
When building on Windows with WSL sharing a disk with the local repository, dependency jars copied to WEB-INF/lib may inherit executable permissions from the local repository.
This normalizes file permissions on copied files to:
- Not executable
- Readable by everyone
- Writable only by owner
Fixes #539

@elharo No new commit landed (head still `e8f0732439`), so the `||` short-circuit is unchanged. The ask: pull the three `set*` calls out of the `if` and apply all three unconditionally, then log if any failed. Re-review as soon as it's in — thanks!

Review Comment:
This test assumes POSIX-style executable bits can be reliably set/cleared via java.io.File. On non-POSIX file systems (notably Windows), File#setExecutable/canExecute semantics differ and this can fail or become flaky. Consider guarding the test with a JUnit assumption that the underlying filesystem supports the "posix" attribute view.
This issue also appears on line 69 of the same file.

Review Comment:
The permission normalization calls ignore the boolean return values from File#setExecutable/#setReadable/#setWritable. On filesystems/OSes that don't support these operations, this will silently fail and the jar may remain executable. Consider checking the return values and logging (at debug) when normalization could not be applied, so the behavior is diagnosable in the environments this change targets.

Review Comment:
The PR description states copied dependencies should be normalized to: not executable, readable by everyone, and writable only by the owner. The tests currently only assert the executable bit; adding an assertion on the full POSIX permissions (e.g., 0644) would better cover the intended behavior.
