[geclipse-dev] LFC Status

[Mateusz Pabiś <uranium@xxxxxxxxxxxxx>]

Hi,

I'm testing today's build, and since GRIA isn't working ;-)
I switched to play around with LFC.

Here is the status:

mount LFC from other services is working,
opening a file, editing it and save works - at least if there is replica 
which allows to open a file(*)

changing checksum value works (only files)
changing comment works (both dirs and files)

deleting entries works (notice: it will remove all replica entries, but 
files on SE are kept intact), also removing directories works

creating directory works, but I encountered problems while listing empty 
 ones, registering replica in them, see (**)

renaming files and directories failed (it worked yesterday)

drag&drop from LFC works
drag&drop to LFC does not

creating new file on LFC (from context menu -> create new) does not work


(*) I've just noticed that SRM return SRM_FAILURE when attempted to open 
some (not all) 0-sized files. Szymon and me are investigating this. Any 
exception from SRM is populated to LFC.

(**) newly created directories have right permissions set to d---------, 
I'm still looking which parameter describes right management for this 
command, I found a solution for files few days ago, so maybe this is the 
same issue.

Known Issues:
- fetching replica information for each file (not directories) takes ~6 
seconds, therefore be patient while listing directory with many files 
inside. Fortunately, LFC runs in threads so GUI stays interactive.

- register a file in replica is tricky.
  1. right click on the LFC node (any, but not the root one),
	this makes LFC to remeber to which LFC server register,
  2. go to any SRM file, right click -> register file
  3. enter name (keep proposed path, or enter new one),

  WARNING: it is allowed to have only one catalogue entry for every 
file  on srm. Therefore, if SRM file is already registered as a replica 
in LFC then it's impossible to register it as another entry. *There is 
no exception saying this happens*, It just creates entry, but without 
any replicas registered.

- opening a file will open first replica that didn't throw an exception 
(or none if this condition is not fulfilled)

- adding more replicas to the file failed without any exception (I'll 
investigate this after this mail)

- registering a file, ends with filesize set to 0 (working on this)

- in 90% there is no information if something went wrong

If you find more issues, please fill a bugzilla item and assign it 
directly to me, thanks.
