# infer-owner
|
||
|
|
||
|
Infer the owner of a path based on the owner of its nearest existing parent
|
||
|
|
||
|
## USAGE
|
||
|
|
||
|
```js
|
||
|
const inferOwner = require('infer-owner')
|
||
|
|
||
|
inferOwner('/some/cache/folder/file').then(owner => {
|
||
|
// owner is {uid, gid} that should be attached to
|
||
|
// the /some/cache/folder/file, based on ownership
|
||
|
// of /some/cache/folder, /some/cache, /some, or /,
|
||
|
// whichever is the first to exist
|
||
|
})
|
||
|
|
||
|
// same, but not async
|
||
|
const owner = inferOwner.sync('/some/cache/folder/file')
|
||
|
|
||
|
// results are cached! to reset the cache (eg, to change
|
||
|
// permissions for whatever reason), do this:
|
||
|
inferOwner.clearCache()
|
||
|
```
|
||
|
|
||
|
This module endeavors to be as performant as possible. Parallel requests
|
||
|
for ownership of the same path will only stat the directories one time.
|
||
|
|
||
|
## API
|
||
|
|
||
|
* `inferOwner(path) -> Promise<{ uid, gid }>`
|
||
|
|
||
|
If the path exists, return its uid and gid. If it does not, look to
|
||
|
its parent, then its grandparent, and so on.
|
||
|
|
||
|
* `inferOwner(path) -> { uid, gid }`
|
||
|
|
||
|
Sync form of `inferOwner(path)`.
|
||
|
|
||
|
* `inferOwner.clearCache()`
|
||
|
|
||
|
Delete all cached ownership information and in-flight tracking.
