I'm mostly wondering how file integrity is ensured. + +Let's say you want to migrate foo.txt from (say) md5 to sha256. Does git annex simply sha256sum foo.txt and rename it in the .git/objects folder to the new sum? Or does it md5sum foo.txt, verify that it's the not corrupt, then sha256sum it and rename to the new sum? + +You could run into problems if you migrate without first verifying; if the file is corrupt and you simply sha256sum and rename it, then the file wouldn't seem corrupt at your next fsck. + +I'm sure you've considered this during the basic design phase of git-annex, but I'd just like to be sure. I'm kind of paranoid when it comes to data integrity. =P |
