Empty slice found error #88

Closed Focshole closed 11 months ago

After inspecting the logs, I noticed an occasional error on a db file during prefetching. It happened occasionally since the 28th of may, always with the community.db file:

ago 01 03:00:04 testmachine pacoloco[727]: repo_db_mirror.go:234: An error occurred for mirror {/repo/archlinux/community/os/x86_64/community.db archlinux 2023-07-16 06:00:01.198244598 +0200 +0200} :empty slice found

The error is generated here https://github.com/anatol/pacoloco/blob/4995568b3e8a062efbee64a410b17b918a31dab0/repo_db_mirror.go#L234

But I suspect the error is being emitted here: https://github.com/anatol/pacoloco/blob/4995568b3e8a062efbee64a410b17b918a31dab0/repo_db_mirror.go#L210

GORM usually emits this error when some fields are missing I suppose. Maybe we should check that this array is not empty, as gorm may fail to save an empty array, but this is just guessing: https://github.com/anatol/pacoloco/blob/4995568b3e8a062efbee64a410b17b918a31dab0/repo_db_mirror.go#L205

Could you post exact error message here?

You can change the code and see where exactly the error happens and whether it fixes the issue.

I believe it is a dup of #86

Oh sorry, I just noticed it was not visible!

It is a different error which happens occasionally, I'll open a PR for the fix when I'll have some time to write it
