2057: fix(dump): Uncompress the dump IN the data.ms r=irevoire a=irevoire When loading a dump with docker, we had two problems. After creating a tempdirectory, uncompressing and re-indexing the dump: 1. We try to `move` the new “data.ms” onto the currently present one. The problem is that if the `data.ms` is a mount point because that's what peoples do with docker usually. We can't override a mount point, and thus we were throwing an error. 2. The tempdir is created in `/tmp`, which is usually quite small AND may not be on the same partition as the `data.ms`. This means when we tried to move the dump over the `data.ms`, it was also failing because we can't move data between two partitions. ------------------ 1 was fixed by deleting the *content* of the `data.ms` and moving the *content* of the tempdir *inside* the `data.ms`. If someone tries to create volumes inside the `data.ms` that's his problem, not ours. 2 was fixed by creating the tempdir *inside* of the `data.ms`. If a user mounted its `data.ms` on a large partition, there is no reason he could not load a big dump because his `/tmp` was too small. This solves the issue; now the dump is extracted and indexed on the same partition the `data.ms` will lay. fix #1833 Co-authored-by: Tamo <tamo@meilisearch.com>
