error if running multiple commands from different shells about mcfly

Thanks, I'll try to fix it.

Hi @pmarreck, I'm sorry to hear that. I haven't seen this before. According to this StackOverflow page, you could try copying the DB and moving it back:

mv ~/.mcfly/history.db temp.db
cp temp.db ~/.mcfly/history.db

Or something similar.

Sorry for the delay. This does sound like a real issue. Odd that I haven't had it happen myself.

I can attest that this happens frequently with me as well. I am using v0.3.3.

I've been unable to reproduce this, but have a possible fix in #60. Would it be easy for either of you to test #60?

Can you provide a snapshot? I don't have Rust installed.
I don't have a reproducer for this issue. I just can use a snapshot and see if the issue reoccurs.

[cantino]

Sure! I included it in this release: https://github.com/cantino/mcfly/releases/tag/v0.3.4

ran into the same issue. and mcfly is generally taking many dozens of seconds after each command to return shell control to me. I've already limited the max history to 10K. Anything else I can do to either start over from a known-good place or repair the sqlite DB or...?

thread 'main' panicked at 'McFly error: Unable to create schema_versions db table (database is locked)', src/history/schema.rs:105:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

FWIW I'm on NixOS currently.

Tried that, didn't help, but I realized that all of my disk operations seem slow as well, so I may have a disk issue; I'm going to look into how to troubleshoot slow disk ops in Linux (any tips welcome of course)
