[nhibernate-issues] [JIRA] Created: (NH-820) External serializer

[NHibernate J. <mik...@us...>]

External serializer
-------------------

         Key: NH-820
         URL: http://jira.nhibernate.org/browse/NH-820
     Project: NHibernate
        Type: Improvement
  Components: Core  
    Versions: 1.2.0.Beta2    
    Reporter: Fabio Maulo
    Priority: Minor


What about to add a config parameter to have an external serializer?

In NHb we can actually use SerializationHelper, we can sill use SerializationHelper like default and we can have an external serializer.

We can introduce a new interface:	
public interface ISerializer
	{

		byte[] Serialize(object obj);
		object Deserialize(byte[] data);
	}

Using an adapter the user can have he's own optimized serializer.

[nhibernate-issues] [JIRA] Closed: (NH-815) SQLQueryImpl fails to bind parameter lists

> The SQLQueryImpl class does not bind parameter lists properly.  This is very easy to reproduce with a simple SQLQuery that has a single named parameter in the WHERE clause (e.g. "where id in (:idList)") and then use the ISQLQuery.SetParameterList("idList", someCollection).  This works with an IQuery but fails with an ISQLQuery.
> I debugged through the source of the 1.2.0 Beta2 and the fix appears very straightforward.  See the code snippet below that indicates where the method argument "parameters" should probably be used instead of the class's NamedParams property.

[nhibernate-issues] [JIRA] Updated: (NH-817) DetachedCriteria Serializable

---------------------------------

    Description: 
DetachedCriteria is serializable in H3.2.
I post the test for DetachedCriteria serializable (NHibernate.Test.Criteria.DetachedCriteriaSerializable).
I'm working to pass the test.

N.B. CriteriaImpl is marked serializable but can't be serialized because RootEntityResultTransformer is not serializable.

  was:
DetechedCriteria is serializable in H3.2.
I post the test for DetachedCriteria serializable (NHibernate.Test.Criteria.DetachedCriteriaSerializable).
I'm working to pass the test.

N.B. CriteriaImpl is marked serializable but can't be serialized because RootEntityResultTransformer is not serializable.

[nhibernate-issues] [JIRA] Commented: (NH-813) CacheKey key is invalid - memcached fails to store objects.

--------------------------------------

A better fix would be to alter MemCachedClient.KeyAsString method to do the right thing for keys of type CacheKey instead of just calling their ToString method.

> The CacheKey derives from IdentifierSpace, which is EntityMetaModel.RootTypeAssemblyQualifiedName.  This name contains spaces, which causes an issue with MemCache, in the 'set' command.  With the spaces in the key, an invalid command is sent to the memcached server.
> I have provided a patch that exposes a new property on EntityMetaModel, RootName (to match the property name in Hibernate), which simply replaces the spaces with underscores '_'.  Now memcached caching works fine.

[nhibernate-issues] [JIRA] Created: (NH-819) Memcached.Client library is using log4net 1.2.9, instead of 1.2.10

[NHibernate J. <mik...@us...>]

Memcached.Client library is using log4net 1.2.9, instead of 1.2.10
------------------------------------------------------------------

         Key: NH-819
         URL: http://jira.nhibernate.org/browse/NH-819
     Project: NHibernate
        Type: Bug
  Components: Contrib  
    Versions: 1.2.0.Beta2    
    Reporter: Ayende Rahien
 Assigned to: Ayende Rahien 
     Fix For: 1.2.0.CR1


This disable the use of MemCached caching with NH 1.2
Temporary solution may be to compile Memcached client ourself, but we lose the strong name that way.
I am going to contact the developers and see if they can push a version with 1.2.10, and then move to that.

DetechedCriteria is serializable in H3.2.
I post the test for DetachedCriteria serializable (NHibernate.Test.Criteria.DetachedCriteriaSerializable).
I'm working to pass the test.

N.B. CriteriaImpl is marked serializable but can't be serialized because RootEntityResultTransformer is not serializable.

[nhibernate-issues] [JIRA] Commented: (NH-814) Resetting of properties after initial set violates constraints we want to protect

Ayende Rahien commented on NH-814:
----------------------------------

Accessing the fields directly usually means either reflection or dynamic co=
de generaion, not something that your everyday code is going to be able to =
do.

I don't agree with this approach of handling security, since if you have ma=
licious code in your appdomain that is able to make calls, you are in a bad=
 state already. But, this discussion is not for the JIRA.

Given the constraints that you have set, I would create an access strategy =
where the strategy would inform the object that it is being modified by NHi=
bernate, and disallow any modifications not done this way.
A simple approach may be setting a flag to say that NHibernate is now doing=
 modification to the object, and having the object check that flag.
Securing this approach is possible by putting the flag in a base class and =
making it internal, so only the access strategy could access it.

[nhibernate-issues] [JIRA] Commented: (NH-814) Resetting of properties after initial set violates constraints we want to protect

[NHibernate J. <mik...@us...>]

Jim Showalter commented on NH-814:
----------------------------------

If nhibernate can access fields directly, then so can anyone/anything else.=
 If they can do that, then the constraints aren't protected. So field acces=
s is deliberately shut off using declarative security. So nosetter doesn't =
work.

Think of nhibernate in the context of a high-security application. For exam=
ple, a banking application. We don't want malicious code to be able to call=
 a method to change a person's account balance. But we have to allow nhiber=
nate to set that balance when it reads an object back from the database. So=
 we have to allow the balance to be set once by nhibernate. But we don't wa=
nt anything that isn't authorized to do so to set that balance again.
