Grouped write of manifest, lock and vendor: could not stat file that VerifyVendor claimed existed: stat "path to package inside vendor": no such file or directory

Running dep ensure
again re-created the vendor folder with all required dependencies.
This can sometimes also be resolved by fixing up the folder permissions, but deleting the folder seems to be the easiest way to fix this.
QUESTION
I'm using https://github.com/coocood/freecache to cache database results, but currently I need to dump bigger chunks on every delete, which costs multiple microseconds extra compared to targeted deletion. fmt.Sprintf("%d_%d_%d")
for a pattern like #SUBJECT_#ID1_#ID2
also costs multiple microseconds. Even tho that doesn't sound like much, in the current ratio of the cache's response time that a multitude slower than it currently is.
I was thinking of using the library's SetInt
/GetInt
which works with int64
keys instead of strings.
So let's say I'm storing in a #SUBJECT_#ID1_#ID2
pattern. The Subject is a table or query-segment-range in my code (e.a. everything concern ACL or Productfiltering).
Let's take an example of Userright.id
is #ID1
and User.id
is #ID2
and Subject ACL
. I would build it as something like this:
