Changes
Fixed handling of trailing directory separators in the
cpcommand. When a target path ends with/or\, the command now validates that the directory exists before copying. If the directory doesn't exist, it returns a clear error message instead of failing later.Added a helper function
hasTrailingDirSeparatorto detect trailing directory separators for both Unix-style (/) and Windows-style (\) paths.Why
Previously, the
cpcommand didn't properly handle trailing directory separators. When users specified a target path liketarget/dir/(expecting it to be treated as a directory), the command would not validate that the directory exists first, leading to confusing error messages later in the copy process. This change ensures that trailing directory separators are explicitly treated as indicating a directory target, and validates that the directory exists upfront.Tests
Added unit tests in
integration/cmd/fs/cp_test.go:TestFsCpFileToNonExistentDir: Tests copying files to both existing and non-existent directories with trailing slashesTestFsCpFileToNonExistentDirWindowsPaths: Windows-specific tests for trailing backslashes (\) and forward slashes (/) on WindowsThe tests verify that:
/) and Windows-style (\) separators are handled correctly
