Requirements for publishing a mobile app

[J. Landman Gay]

A web app runs in a browser; that's the main difference. LC Create makes 
web apps.

It occurred to me that you will need to deal with race conditions, whether 
the app is a web app or a standalone that reads a stack from a server. A 
race condition is when more than one person is using the app at the same 
time. One person saves changes and it is uploaded to the server. If another 
person is using the app simultaneously and then saves their own changes, it 
will overwrite the first person's changes. To deal with that you'll need to 
set some sort of flag that the standalone checks before sending changes to 
the server. Usually the flag is just a plain text file. If the flag is set 
to true, the app needs to wait until the flag is false before redownloading 
the changed stack, applying the second user's changes, and then uploading 
the revised stack to the server again.

I've never had to deal with that since all my own work has been static and 
the working stack has always been read-only (mostly educational materials.) 
I remember that Andre was very cautious about race conditions and posted 
his technique on the mailing list some years ago but unfortunately I didn't 
save it.
