// In Bun, process.cwd() doesn't affect the behavior of `path.resolve()` (it uses
|
|
// getcwd(2)). This has the following implications:
|
|
// 1. overriding process.cwd() has no affect on path.resolve();
|
|
// 2. getcwd isn't affected by $CWD, so it cannot be removed that way;
|
|
// 3. The Bun CLI caches cwd on BunProcess.m_cachedCwd at startup, so deleting
|
|
// it after the process starts keeps `process.cwd()` at the original value;
|
|
// 4. If the current directory is deleted before starting bun, the CLI catches
|
|
// it and exits with an error code.
|
|
//
|
|
// Because of all this, I cannot reproduce a scenario where cwd is empty, so
|
|
// this test is commented out.
