Please describe the problem.

When adding plenty of files to my git annex repository, I encounter recurring sqlite errors.

What steps will reproduce the problem?

Create a git annex repo, add thousands of annexed binary files, and add thousands of small files tracked only with git.

What version of git-annex are you using? On what operating system?

Triying to solve this problem, I found a part of answer in the form of a similar problem encountered here :

Deleting git annex databases and running git annex fsck didnt do the trick:

rm -rf .git/annex/keys/db .git/annex/keys/db-wal
git annex fsck --incremental -J4
git add $(git ls-files --others | grep txt)
# Again, plenty of sqlite errors :()

It seems like a big overhead to add files tracked only by git in git annex repo. I know there are hooks/filters that catch and recover annexed files after modification but is it possible to disable these git annex hooks/filters when adding files that shouldn't be annexed ?

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Oh yeah, I am still discovering this powerfull git annex tool.

In fact, collegues and I are forming a group during the process to exchange about different use cases, encountered problems and help each other.

This bug still exists, and there's a more recent bug report documenting how it behaves in WSL now.

So I don't think there's any point leaving this open, closing as a duplicate. done --Joey
