    fix Access denied issue on windows

    I tried to use single mode in Store configuration, it worked fine on linux but fails on windows with this error

    'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 5, kind: PermissionDenied, message: "Access is denied." }
    

    when investigated found that the issue is rename function which tries to rename a file still oppened. so changed it to be the last call and dropped the values of tem_file and file to close the oppened files and then connect them, also there are some problems in unit testing for windows, specially with multthreading for these methods

  • Q: Is the single file json store mode safe for use through multiple processes at once?

    Q: Is the single file json store mode safe for use through multiple processes at once?

    Thank you for the awesome library!

    I am trying to write a CLI where JFS is used. Users might invoke this CLI in parallel. I can see unit tests for validating multi threaded access, but I couldn't see anything concrete for multi process access.

  • Derive debug trait for public structs

    Derive debug trait for public structs

    I think it'll be good to have a default implementation. Without this, users cannot use #[derive(Debug)] on their structs that use JFS as a field. Hence users have to implement debug for the whole struct manually due to just one field.

    Also see:

  • Generify paths

    Generify paths

    This looks like a great project. I'm looking at using it, thanks for the work.

    I cleaned up a few things in the tests related to where the data is stored. Always put it in target/ so that there's no pollution in the local dir.

    I also generified the constructors so that you can pass in Path based parameters. I need to build some wrappers on the actual DB file, so this was going to be important. Added some docs on those methods too.

  • Force flush changes to filesystem

    Force flush changes to filesystem

    👋 Thank you for writing JFS! I am using it as an alternative store for a side project. While running my tests, I noticed that my delete case would sporadically fail. It does a bunch of inserts, then a bunch of deletes and then reads to see if they still there.

    I think adding a f.sync_all()? at the end of save_object_to_file should at least alleviate the case.

    I can open a PR if you want.
