[Yanel-dev] yarep symlinks

[Josias Thöny]

Hi all,

Some yarep implementations seem to allow some kind of symlinks, i.e. two 
or more different paths which have the same uuid and therefore point to 
the same file.

Example:
path1: /foo/            -> uuid: 1234
path2: /foo/index.html  -> uuid: 1234

Now index.html is a child node of foo, so foo is basically a child of 
itself, which leads to some problems.
For example if someone wants to delete all children of /foo but not /foo 
itself, the repository will delete /foo/index.html, which means that the 
file 1234 is deleted, but /foo still points to it, and the repository is 
  broken...

I'm not sure how to fix this.
My question is, do we really need symlinks, and what are they used for?
I guess they are used to allow calling the urls /foo/ or /foo/index.html 
and both should return the same page.
But should that really be handled in the repository layer? My feeling is 
that it does not belong there.
WDYT?
