@ -2,4 +2,12 @@ to work around [[forum/original_filename_on_s3/]], i need to get the key from a
could i optimise this by simply doing a `readlink` call on the git checkout? it sure looks like `readlink | basename` is all I really need, and that can probably be done below 10ms (4ms in my tests). how reliable are those links anyways, and is that what lookupkey does?
similarly, i wonder if it's safe to bypass git-annex and talk straight with git to extract location tracking? i can jump from 90ms to below 10ms for such requests if I turn `git annex find <file>` into the convoluted:
<pre>
git annex lookupkey $file
printf $key | md5sum
git cat-file -p refs/heads/git-annex:$hash/${key}.log
</pre>
