Occasionally seeing problems loading migrations in the pg test harness #56

Closed jayvdb closed 5 months ago

jayvdb commented 1 year ago

line 22 below is 

butane::migrations::copy_migration(disk_current, mem_current).unwrap();

Intermittent failure:

Also occurred earlier today for Running tests/basic.rs ..., same error, only pg.

Note to self, it occurred when modifying butane_core/src/*.rs

Electron100 commented 1 year ago

I suspect that if we go forward with #60 this will be solved as a side-effect since the time of file IO to the migration structures on disk will be more tightly controlled.

jayvdb commented 1 year ago

I havent seen this in quite a while, and was wondering if it had fixed itself, but just saw it now in r2d2_pq test.

jayvdb commented 5 months ago

I tried to reproduce this by repeatedly running tests in butane/ to no avail.

Then repeating tests in / (all projects), it quickly appeared, but still takes many repeats.

I added a bunch of .unwrap() and it fails in self.lock_shared() here:

impl Migration for FsMigration {
    fn db(&self) -> Result<ADB> {
        let _lock = self.lock_shared().unwrap();
        let mut db = ADB::new();
        self.ensure_dir().unwrap();

With https://github.com/Electron100/butane/pull/213 (first commit; "Create dir before lock"), the problem now occurs a bit later in the pg helper

I can reliably trigger this by running the tests repeatedly in the console without rust-analyzer running, and then opening VS code with rust-analyzer doing its thing on startup.

This would explain why it never occurs in CI.

jayvdb commented 5 months ago

so im pretty confident it is https://github.com/Electron100/butane/blob/master/butane/build.rs doing the deleting. curious it is never sqlite tests which fail.

jayvdb commented 5 months ago

A quite easy way to reduce this to negligible effect is to update build.rs to find the latest updated timestamp of files in butane/tests , and only delete files in butane/.butane/ if they are older than that. I'll look into that.
