QDomDocument toString() producing different results

[goldstar2154]

Hi everyone.

So situation is:

QDomDocument::toString()

producing different results.
This happens cause of QHash now have random seeding (against hash attacks).

Problem is - we generate sign based on xml-string produced by toString() , so when we check sign we got sign mismatch because of different strings.

Possible solutions like

qSetGlobalQHashSeed(0);

is not solution because it works only at same machine but not work on different machines.

So is there are way produce identical xml-strings on different PCs?

The only possibility I see is to find-and-replace QHash with QMap inside QDomDocument sources and re-compile Qt. This would also have licensing implications though

Thanks for idea, i think we can build our own QDom* classes and make lib for application.
Also possible solution is canonical serializer, that will save xml in right way, but both solutions require much more code than .toString() :)
