rhizofs's Issues

Edit a file in mounted directory using a text editor, notice that changes are updated but not the timestamp. GThis filke was just updated:

This is an issue when using make.

rhizofs crashes on MacOS when a server public key is used for encryption

This seems to be limited to MacOS, and only happens with encryption. Furthermore, from the lldb output it's also limited to the case where no keypair is set for the client, so it generates its own on the fly. I finally got some data to work on:

Command line was: rhizofs -f --pubkeyfile=/Users/okurth/.config/rhizofs/ubuntu2-devel.key tcp://192.168.249.164:1234 ./ubuntu2-devel

Somehow it runs into this:

    frame #3: 0x000000010909bfdf libsodium.23.dylib`sodium_misuse + 63

but following the code in libsodium I wasn't able to find where sodium_misuse() is called and why. The function calls abort() unless a handler is set.
