[Xerte] Re: XOT

Pat,

How about a table in MySQL that stores the open LO file name and a
session cookie file name (session cookie could store name of person
editing the LO) when it is opened/created. Then when someone else
attempts to open the LO, check the db for the session cookie name and
see if the cookie still exists? Deny access if the cookie still exists.
Garbage collection should handle deleting the cookie if the person
closes browser without logging out. Is that idea cunning enough?

Hi Jason,

It's great to see the The fire service using XOT.

I can only comment on the second point directly. 

When a shared project is edited, it creates a file on the system to stop
someone else editing it. The editor window closing should delete this
file. Sadly like on say Facebook, a user's session can expire and then
the system can't delete the file.

Whenever we tested it, it worked, but this problem came up so we made
the change to warn people - it used to stop people completely.

Without some cunning idea code wise to stop it, it's a headache but it's
probably the safest option - two people editing at once could corrupt a
file.

I know it's not the best answer, but will start off a chat on the
developer list to see what comes up.

Pat

the user, instead when the learner clicks on the scroll arrow the LO
turns grey and nothing is viewable. We have restricted to loading only 5
videos to each slide as an interim measure but wondered how we could fix
this please?

continue you could lose work(or similar)'. This has happened on a number
of occasions and each time we have confirmed through telephone calls
that the other person is not online & therefore not editing the LO. Is
there something we should be specifically doing when sharing objects to
close them down?

and not the true result of 4 out of 4, I attach a screen shot for you
that captures this.
