flysystem-webdav - WebDAVAdapter.php - createDirectory() not working allways

[chris5560]

In "WebDAVAdapter.php" file, the function "createDirectory" does not work,
if a directory specified for "$path" starts with a "." or "/". The function will "return" directly.
Line 219 says "return" it must be "continue" and everything works fine.
Please fix it.
Thanks Christian

This would not only affect WebDAV, but at least also InMemory, StaticInMemory and ZipArchive.

Example test:

/**
 * @test
 *
 * @dataProvider directoryPrefixProvider
 */
public function ensure_prefixed_directories_are_created_issue_1689(string $path): void
{
    $this->runScenario(function () use ($path) {
        $adapter = $this->adapter();

        $adapter->createDirectory(
            $path.'test',
            new Config()
        );

        $this->assertTrue($adapter->directoryExists('test'));
    });
}

public static function directoryPrefixProvider(): iterable
{
    yield [ './'];
    yield [ '/'];
    yield [ '/./'];
}

And what about creating a file ./my_fily.txt. This results into errors, too.

If you think it's worth, feel free to create a PR to fix it.
