Thanks! I'll give it a try tomorrow.
So now "rio_rw.c" has almost all the needed code to get the tags
of a (temporary or fids0/*/??0) file and update the requiered
properties of some fid. Therefore, in order to implement full
tune copy-to capabilities in lkarmafs, I propose to add a new
function in rio_rw.c such as:
int lk_rio_updatePropsFromTags(
int rio, uint32_t fid, const char *filename);
For a given `fid', lkarmafs will decide whether to create a
(head-tail) temp file somewhere or to just use the fids0/*/??0
name for the `filename' argument. Unless someone has some
comments against, I'll start with this idea tomorrow.
It's a pity that we can not use the just-uploaded file under the
(virtual) lkarmafs filesystem hierarchy, because this would make
things much simpler (in lkarmafs). I'll dig a bit more into the
low-level FUSE lib functions to see if there is some additional
possibility that we've missed so far...
Best,
EV.
