2
3Infer the owner of a path based on the owner of its nearest existing parent
4
5## USAGE
6
7```js
8const inferOwner = require('infer-owner')
9
10inferOwner('/some/cache/folder/file').then(owner => {
11 // owner is {uid, gid} that should be attached to
12 // the /some/cache/folder/file, based on ownership
13 // of /some/cache/folder, /some/cache, /some, or /,
14 // whichever is the first to exist
15})
16
17// same, but not async
18const owner = inferOwner.sync('/some/cache/folder/file')
19
20// results are cached! to reset the cache (eg, to change
21// permissions for whatever reason), do this:
22inferOwner.clearCache()
23```
24
25This module endeavors to be as performant as possible. Parallel requests
26for ownership of the same path will only stat the directories one time.
27
28## API
29
30* `inferOwner(path) -> Promise<{ uid, gid }>`
31
32 If the path exists, return its uid and gid. If it does not, look to
33 its parent, then its grandparent, and so on.
34
35* `inferOwner(path) -> { uid, gid }`
36
37 Sync form of `inferOwner(path)`.
38
39* `inferOwner.clearCache()`
40
41 Delete all cached ownership information and in-flight tracking.
