dear all,
we had a dramatic incident last evening, one of the group.xmls got
corrupted by two parallel requests doing exactly the same thing.
I described the whole use case and solution propsal including a workaround
here:
https://github.com/wyona/security/issues/1
This is just to let Yanel customers know that highly multi-threaded realms
should be aware that most Yarep-Methods are not multi-threadable and must
be synchronized in the realm's code.
The code proposal to solve it is included in the issue description above.
If really needed, I can also create a pull request for this. But I think
the idea is clear how to fix it.
Cheers
Balz
