There was a problem hiding this comment.
If we're seeking from the end, the offset will already be negative.

Actually, this was wrong. It should have been Nvm. Seeking to the end is correctly done with a s.size-1+offset.Seek(-1, SeekEnd).

Build and tested with commit 361bb5f. |

Thanks for catching that (and bugging me to write a test)! |

(ok, there's definitely a bug here, I'll look into it when I get a chance) |
Fixes symlink sizes.
1. Require files to have known sizes. We can add support for unknown sizes _later_ but we can't use ServeContent for those files. 2. Replace the `sizeReadSeeker` with a `lazySeeker`. This one makes no assumptions about how it's used so we're less likely to run into weird bugs.
We should be _resolving_ symlinks (sometimes, still need to figure out when to do this WRT IPNS). However, that's a larger feature.
