[Gnu-arch-users] [Bug] Cacherevs contain inode sigs

[Aaron Bentley]

Since cacherevs are meant to represent source trees, they shouldn't 
contain junk files.  But they contain inode signatures.  I've tested 
several archives, including address@hidden

This means that different results will be produced by downloading a 
cacherev and applying a changeset, versus downloading a cacherev for the 
exact revision.  Since only junk files will differ, tla delta would 
produce an empty changeset, but diff would see differences.

I've been generalizing in my head that a cacherev is a changeset too-- a 
targile being a kind of changeset between no directory and a full one. 
But since changesets don't affect junk files, this isn't accurate.

Inode sigs are a singularly useless thing to store in cacherevs, since 
they will always fail to match.  So this doesn't look intentional.  Must 
be a bug.
