Re: [RavenDB] Math.Random() in Patch scripts

[Oren Eini (Ayende Rahien)]

a) You cannot create a guid using random.

b) You can use this: http://stackoverflow.com/questions/424292/seedable-javascript-random-number-generator

Hi all,

Every call to Math.Random() in a patch script returns the same number.
I'm using Math.Random() to create GUIDs, so I need some unique numbers.
What can I do? Is this to be considered a bug?

no wonder it gives back the same result when it gets the same seed, doh! Sorry!

Hi,

I traced this problem to a bug in Jint version 2.4, which RavenDB is still using. It was fixed in 2.4.1 in this commit: https://github.com/mediaclip/jint/commit/a74013b5e66fecd01df1d483823b8766a892db7a.

I've attempted to use several of these pseudo-rng libraries but Jint fails to parse them in the ScriptedPatchRequest, giving no error. Have you been successful in including it in a JS patch?

Thanks,

George
