This file-locking API is intended to map directly to the native locking facility of the underlying operating system. Thus the locks held on a file should be visible to all programs that have access to the file, regardless of the language in which those programs are written.

Thanks, I’ll try the FileLock again. I tried it before, but I thought it didn’t work properly across processes.

Interesting. So far concurrency semantics of the replikativ libraries where done inside the JVM, konserve does not support safe multi-process write access yet.

Cool. I’ve got this figured out now with clj-kondo using FileLock
borkdude 2019-04-01T18:33:32.037300Z
it’s pretty easy actually to lock a whole dir

Ok. Feel free to send a link to the soure code where you do it when you are ready. I would transfer it to the JVM filestore.

We integrated the latest changes of the datascript code base into datahike and released it as a beta version 0.2.0-beta. Feel free to test and comment.
