        wrong.

2010-05-27  Jb Evain  <jbevain@novell.com>

        for Moonlight Elevated Trust

2010-03-23  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager_2_1.cs: Add an internal HasElevatedPermissions

        * SecurityContext.cs: Don't use WindowsIdentity under NET_2_1

2009-09-09  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs, SecurityManager_2_1.cs: Replace existing

2009-03-19  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Remove VerificationException (not used from
        the runtime anymore) and add FieldAccessException (which is now, 
        or soon will be, required/used by the runtime).

2009-02-19  Rodrigo Kumpera  <rkumpera@novell.com>

        * SecurityManager.cs: Make core-clr work under non 2.1 profiles.

2008-09-15  Jb Evain  <jbevain@novell.com>

        * SecuritySafeCriticalAttribute.cs: Include SecuritySafeCritical in

        * SecurityElement.cs
        * SecurityContext.cs
        * NamedPermissionSet.cs
        * HostProtectionException.cs: Fix parameter names

2008-01-02  Sebastien Pouliot  <sebastien@ximian.com> 

        * SecureString.cs: Fix InsertAt buffer calculation. Fix #350820

2008-01-02  Sebastien Pouliot  <sebastien@ximian.com>

        * SecureString.cs: Don't forget length in Copy. Fix #350840

2007-11-07  Atsushi Enomoto  <atsushi@ximian.com>

        * SecurityElement.cs :
          set_Text() should unescape the input string. get_Text() should
          return unescaped string. It also applies to attribute value.
          ToString() should return valid (escaped) XML.

2007-10-14  Gert Driesen  <drieseng@users.sourceforge.net>

        * SecurityElement.cs: In ctors, do not assign to Tag property to
        ensure exception message match that of MS. In Tag property, set name
        of parameter in ArgumentNullException and do not filter out
        namespace prefixes. Modified Text property to allow null values
        after change to IsValidText that no longer considers null value as
        valid. Avoid NRE in Escape.

2007-08-28  Mark Probst  <mark.probst@gmail.com>

        * SecurityManager.cs: Changed method argument of
        LinkDemandSecurityException to IntPtr and removed the assembly
        argument (which can be gotten to via the method), to avoid having
        to embed reference object values in the native code.

2007-08-20  Mark Probst  <mark.probst@gmail.com>

        * SecurityManager.cs: Changed arguments of MethodAccessException
        to IntPtr, to avoid having to embed reference object values in the
        native code.

2007-08-20  Mark Probst  <mark.probst@gmail.com>

        * SecurityManager.cs: Added two methods needed for CoreCLR
        security.

2007-08-08  Atsushi Enomoto  <atsushi@ximian.com>

        * SecureString.cs : commenting out internal call. It somehow seems
          to cause timeout on the buildbots :(

2007-08-07  Atsushi Enomoto  <atsushi@ximian.com>

        * SecureString.cs : adding notes that ProtectedMemory is not
          implemented for non-windows environment.

2007-08-07  Atsushi Enomoto  <atsushi@ximian.com>

        * SecureString.cs : Decrypt() and Encrypt() now use icall wrapper
          to ProtectedMemory in System.Security.dll.

2007-02-23  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionSet.cs: Fix InvalidCastException on non-CAS permissions.
        Fix bug #80936.

2006-06-16  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityContext.cs: Don't skip the calling callBack if we don't call
        CompressedStack.Run (#78652).

2006-06-15  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityContext.cs: Don't call CompressedStack.Run if we don't have
        a compressed stack in the context (which can now happen because of 
        #78652). This should fix MWF bug #78652 (BeginInvoke under 2.0).

2006-04-07  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityException.cs: Show Evidence correctly (it's a collection) 
        but avoid showing the Hash evidence (it's way too big to be useful).

2005-11-11  Sebastien Pouliot  <sebastien@ximian.com> 

        * SecureString.cs: Completed InsertAt, fixed Alloc not to re-alloc a
        block of the same size. Fixed missing encryption for the char* ctor.
        Only missing is access to ProtectedMemory do to the [en|de]cryption.

2005-10-30  Sebastien Pouliot  <sebastien@ximian.com> 
 
        * PermissionSet.cs: Forgot to remove virtual from 2.0 IsSubsetOf.

2005-10-29  Sebastien Pouliot  <sebastien@ximian.com> 
 
        * PermissionSet.cs: Another update to corcompare shows that even more
        methods are not virtual in 2.0 final.

2005-10-28  Sebastien Pouliot  <sebastien@ximian.com> 
 
        * PermissionSet.cs: Some methods are no more virtual in 2.0 final.

2005-10-28  Sebastien Pouliot  <sebastien@ximian.com>

        * SecureString.cs: Changed the previous (and partial) managed 
        implementation to one (that will be) based on ProtectedMemory. Work in
        progress...

2005-10-17  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionSet.cs: If the current permission set is unrestricted then
        we must allow "permit only" for unrestricted (all other case are known
        to be too restrictive).

2005-09-22  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Added [Obsolete] on SecurityEnabled for 2.0 (as 
        it cannot be turned off on MS runtime anymore). Removed dependecies
        on PermissionSetCollection as this class (related to *Choice actions)
        didn't make it to 2.0 RC.

2005-09-02  Sebastien Pouliot  <sebastien@ximian.com>
 
        * CodeAccessPermission.cs: Fix Deny for permissions that do not return
        null for empty intersection (common on flags-based permissions).
        * PermissionBuilder.cs: Add an helper call to create an empty 
        (PermissionState.None) permission from a type.
        * SecurityManager.cs: Added AppDomain support in InheritanceDemand. 
        Fixed some another small difference between 1.x and 2.0 (wrt 
        unrestricted permissions). Fixed error reporting for InheritanceDemand
        (was LinkDemand).

2005-06-30  Sebastien Pouliot  <sebastien@ximian.com> 

        * SecurityManager.cs: Fixed inheritance demands for 1.x.

2005-06-22  Sebastien Pouliot  <sebastien@ximian.com> 

        * CodeAccessPermission.cs: Fix Unrestricted PermitOnly (which is like
        a no-op). Speed up Assert if Unrestricted.
        * HostSecurityManager.cs: Updated FIXME description.
        * PermissionSet.cs: Remove Copy() of the permission set when non-CAS
        permissions are used (replaced by an array of bools). Completed Assert
        support by re-using the array of bools. Updated TODO descriptions.
        * SecurityException.cs: Added evidence (if available) in the ToString
        description of the exception.
        * SecurityManager.cs: Reworked CheckExecutionRights to get the correct
        behavior.

2005-06-20  Sebastien Pouliot  <sebastien@ximian.com> 

        * CodeAccessPermission.cs: Removed redundant and unrequired TODO.
        * PermissionSet.cs: Some 2.0 optimizations (because sets are simpler
        without the special case for identity permissions).
        * SecurityManager.cs: Shortcut for ResolveIdentityPermissions (in 2.0)
        and some more declarative security syntax updates.

2005-06-16  Sebastien Pouliot  <sebastien@ximian.com> 

        * PermissionSet.cs: Added support for non-CAS permissions in the
        IsSubsetOf method.
        * SecurityManager.cs: Simplified IsGranted and added support for 2.0
        (where all permissions support unrestricted). Changed desclarative 
        security syntax not to use flags (like the rest of the source code).

2005-06-16  Sebastien Pouliot  <sebastien@ximian.com> 
 
        * NamedPermissionSet.cs: A default NamedPermissionSet is Unrestricted.
        * SecurityManager.cs: Simplified LinkDemandFullTrust as FullTrust is
        immutable.

2005-06-14  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Added ResolvingPolicyLevel property to enable
        support for FullTrustAssemblies during policy resolution. Reworked
        (simplified) locking. Moved check for CheckExecutionRights to the 
        "right" place.
        * PermissionSet.cs: Added shortcut in GetPermission(Type).

2005-06-08  Sebastien Pouliot  <sebastien@ximian.com>

        * AllowPartiallyTrustedCallersAttribute.cs, HostSecurityManagerFlags.cs
        IEvidenceFactory.cs, IPermission.cs, ISecurityEncodable.cs,
        ISecurityPolicyEncodable.cs, IStackWalk.cs, NamedPermissionSet.cs,
        PolicyLevelType.cs, SecureString.cs, SecurityElement.cs, 
        SecurityZone.cs, UnverifiableCodeAttribute.cs, VerificationException.cs
        XmlSyntaxException.cs: Fix 2.0 beta2 API changes (which is mostly 
        adding ComVisible attributes to classes).

2005-06-01  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionBuilder.cs: Removed unification stuff. This is done at a 
        lower level.
        * SecurityManager.cs: Split loading PolicyLevel in two phases. The
        PolicyHierarchy is now available after phase 1 which ensures we can
        load permission from outside corlib.

2005-05-28  Sebastien Pouliot  <sebastien@ximian.com>

        * HostSecurityManager.cs: Added check for ActivationArguments in 
        application evidences.

2005-05-27  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Allow unrestricted identity permissions in
        2.0.
        * PermissionBuilder.cs: New. Internal class to help create permission
        instances from XML or with a fully qualified name. This class also 
        deals with unification.
        * PermissionSet.cs: Use PermissionBuilder to create permissions in 
        FromXml method. Many 2.0 fixes (mostly to support unrestricted 
        identity permissions)

2005-05-26  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Fix typo for PermitOnly. Added ComVisible 
        attribute for NET_2_0 profile.
        * PermissionSet.cs: Changed static string to const. Added ComVisible 
        attribute for NET_2_0 profile.
        * SecurityContext.cs: Capture the identity token but don't create a 
        WindowsIdentity instance unless required (e.g. Run). This requires 
        less privileges (so it runs better that way under CAS).

2005-05-25  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityException.cs: PermissionState isn't always serialized 
        (depending on the security policy) so it cannot always be deserialized
        too (and this must work without throwing exceptions).

2005-05-20  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityContext.cs: Includes more methods in NET_1_1 to enable 
        ThreadPool.UnsafeQueueUserWorkItem to work properly (i.e. without
        stack propagation).

2005-05-16  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionSet.cs: Add support for "hidden" read-only mode (as used
        by PolicyStatement).
        * SecurityFrame.cs: Add some debugging code in the ToString method.
        * SecurityManager.cs: Changed internal API so we can display the 
        permission that failed in a PermissionSet (e.g. assembly or appdomain).

2005-05-11  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: GetZoneAndOrigin is present in 1.1 too (but is 
        hidden from mono-api-info because of the LinkDemand for ECMA key).

2005-05-09  Sebastien Pouliot  <sebastien@ximian.com> 
 
        * SecurityContext.cs: That was the wrong place to capture the stack.

2005-05-09  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityContext.cs: Capture the CompressedStack when the current 
        context one is empty.
        * SecurityManager.cs: Class is now static (2.0).
        * SecurityTreatAsSafeAttribute.cs: Fixed AttributeTargets.

2005-05-06  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Reworked frames check to check only for
        the stack modifiers. Throwing a SecurityException now calls Assembly.
        UnprotectedGetName () to avoid throwing (recursively) other 
        SecurityExceptions.
        * PermissionSet.cs: Reworked frames check to include Assembly (moved) 
        and AppDomain (new) transitions.
        * SecurityFrame.cs: Added Domain member to match the runtime structure
        definition. Removed debugging code (will be moved into the runtime 
        later) as it can cause SecurityException is some cases.
        * SecurityManager.cs: Added a method to check if a PermissionSet is
        granted by an AppDomain.

2005-04-28  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionSetCollection.cs: Updated wrt beta2. Seems this will be
        removed before 2.0 final.
        * HostProtectionException.cs: Updated wrt beta2. Added TODO as it 
        isn't support by the runtime.
        * SecurityContext.cs: Updated wrt beta2. Class is now internal in 
        NET_1_1 to allow the compressed stack propagation to other threads.
        * SecurityCriticalAttribute.cs: Added support for property Scope.
        * SecurityException.cs: Removed PermitOnlySetInstance property to 
        match beta2.
        * SecurityTransparentAttribute.cs: Fixed AttributeUsage. Added TODO
        as it isn't support by the runtime.
        * SuppressUnmanagedCodeSecurityAttribute.cs: Added delegates to usage
        in NET_2_0.

2005-04-27  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityCriticalScope.cs: New. Enum introduced in 2.0 beta2.
        * SecurityTreatAsSafeAttribute.cs: New. Attribute introducted in 2.0
        beta2.

2005-04-25  Sebastien Pouliot  <sebastien@ximian.com>

        * HostSecurityManager.cs: Now refers to HostSecurityManagerOptions.
        * HostSecurityManagerFlags.cs: Renamed enum to 
        HostSecurityManagerOptions.

2005-03-31  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityException.cs: Added try/catch in GetObjectData because the
        PermissionState property is serialized only if both ControlEvidence 
        and ControlPolicy are granted.

2005-03-24  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Fixed PermitOnly when used in a set. Added
        an InheritanceDemand for ControlEvidence and ControlPolicy on the 
        class.
        * PermissionSet.cs: Added an InheritanceDemand for MS public key on 
        class.
        * SecurityException.cs: Moved PermissionType up in ToString as this
        property isn't restricted (i.e. will be part of the output even if
        the other properties can't make it).

2005-03-15  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Fixed depth for starting the stack walk
        (imperative) and fixed assert condition.
        * PermissionSet.cs: Fixed depth for starting the stack walk.
        * SecurityFrame.cs: Reversed stack. Added optional debugging code.

2005-03-14  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Fix CodeAccessPermissionTest.CustomCAS unit test
        when --security is enabled (code was over-optimized ;-).

2005-03-11  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Added methods to support reflection query and 
        invoke for LinkDemand and InheritanceDemand. Added method to do a
        stack walk (demand) when a p/invoking (called by JIT generated code).

2005-03-02  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs,
        * PermissionSet.cs: Don't throw NotSupportedException if the security 
        manager (SecurityManager.SecurityEnabled) is off.

2005-02-25  Sebastien Pouliot  <sebastien@ximian.com> 

        * CodeAccessPermission.cs: Implement Equals for NET_2_0 profile.
        * PermissionSet.cs: Added code to decode the metadata format used for
        declarative security in 2.0 (except enums and arrays now).
        * PermissionSetCollection.cs: Added code to decode from the new metadata
        format used for declarative security in 2.0.
        * SecurityManager.cs: Added support for LinkDemandChoice, Inheritance
        DemandChoice and DemandChoice (2.0). Added support for reflected 
        LinkDemand (promotes the demand to a full Demand).

2005-02-15  Sebastien Pouliot  <sebastien@ximian.com> 

        * SecurityException.cs: Show the method informations when displaying a
        SecurityException.
        * SecurityManager.cs: Reworked InheritanceDemand implementation. Added
        a new method to throw a SecurityException for an InheritanceDemand.

2005-02-10  Sebastien Pouliot  <sebastien@ximian.com> 
 
        * SecurityManager.cs: Reduced the number of parameters for LinkDemand.
        Removed a (forgotten) debugging message.

2005-02-10  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityException.cs: Show more information when a SecurityException
        occurs to help debugging.
        * SecurityManager.cs: Reworked LinkDemand implementation. Supply more
        informations when throwing a SecurityException for LinkDemand.
        * PermissionSet.cs: Remove (now) unused code for LinkDemand.

2005-02-08  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Updated code for LinkDemand (and it's special
        cases).

2005-01-27  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Process Deny for empty PermissionSet (e.g.
        an unrestricted permission set must deny all permissions).
        * SecurityException.cs: Added missing HResult to NET_2_0 constructors.
        Added securiy permissions for GrantedSet, RefusedSet and 
        PermissionState properties (to avoid leaking policy informations). 
        Make sure that ToString() always works.
        * SecurityManager.cs: Remove outdated comments (now that the 
        declarative attributes are in place).

2005-01-25  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Now use Environment.InternalGetFolderPath to
        avoid recursion when initializing security policies.

2005-01-24  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Made ThrowSecurityException static so it 
        can be reused from PermissionSet.
        * SecurityManager.cs: Use the new icalls for SecurityEnabled and
        CheckExecutionRights properties. Fix IsGranted for unrestricted 
        permissions. Set type correctly when loading policy files.
        * PermissionSet.cs: Now supports unrestricted permission set when
        evaluating demands.

2005-01-22  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityFrame.cs: Keep RuntimeDeclSecurityEntry enum in sync with
        runtime (added index to allow AOT to work with declarative security).

2005-01-19  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Fix the regressions on NET_1_1 introduced by my
        refactoring 10 days ago.

2005-01-11  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionSet.cs: Simplified GetHashCode as two exact copies may 
        have different hash codes (documented as such). This fix some unit
        tests for 2.0.

2005-01-10  Sebastien Pouliot  <sebastien@ximian.com>

        * HostSecurityManager.cs: Fix signature as DetermineApplicationTrust
        doesn't return a boolean anymore.
        * SecurityElement.cs: The attributes and children elements are not
        indented in 2.0. This fix many unit tests that do string compares.
        * PermissionSetCollection.cs: We can't trust all IList implementations
        to throw the ArgumentOutOfRangeException - so we better do it here.

2005-01-09  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: CheckAssert, CheckDemand, CheckDeny and
        CheckPermitOnly are no more publicly avaiable in Fx 2.0 and have been
        changed to internal for all profiles. Updated comments to reflect the
        (better) documentation available with 2.0.
        * HostSecurityManager.cs: Updated to Dec CTP specs. There is missing
        documentation (and/or classes) to implement completly the 
        DetermineApplicationTrust method at this point.
        * PermissionSetCollection.cs: Completed implementation.
        * PermissionSet.cs: Fix the case where Assert, Deny and PermitOnly 
        must be ignored for non-CAS permissions.
        * SecurityManager.cs: Refactored resolve methods to implements 
        ResolveSystemPolicy (a resolve without the AppDomain policy level).
        Added a default implementation for GetZoneAndOrigin (empty ArrayList) 
        which seems to be right (at least) for FullTrust. 

2005-01-08  Sebastien Pouliot  <sebastien@ximian.com>

        * AllowPartiallyTrustedCallersAttribute.cs: Cleanup;
        * HostSecurityManagerFlags.cs: Updated flags for 2.0 Dec CTP.
        * SecurityCriticalAttribute.cs: New. New 2.0 attribute.
        * SecurityTransparentAttribute.cs: New. New 2.0 attribute.
        * SuppressUnmanagedCodeSecurityAttribute.cs: Cleanup;

2004-12-20  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Refactored to play more nicely with 
        PermissionSet and the new functionalities in the runtime.
        * PermissionSet.cs: Modified to use the new functionalities in the
        runtime. This allows the declarative stack modifiers to work in a 
        stack walk.
        * SecurityFrame.cs: New. This is the managed representation of the
        security informations associated with a stack frame. This current
        version only support declarative stack modifiers.
        * SecurityManager.cs: Modified to use the new functionalities in the
        runtime.

2004-11-30  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs:
        * NamedPermissionSet.cs:
        * PermissionSet.cs:
        * SecurityElement.cs:
        * SecurityException.cs:
                Added ComVisible attributes to match 2.0 October Preview.
        * SecureString.cs: Added an internal method to get the unencrypted 
        string (required to use the string inside mscorlib).

2004-10-19  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Changed private static methods to use a single
        parameter (as method permissions overrides class permissions for
        demand, assert, deny and permitonly).

2004-10-15  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Implemented stubs (soon to be icalls) to
        get/set/clear the current security frame on the stack. Implemented
        Assert, Deny and PermitOnly with the new methods. Changed Demand to
        use the CheckAssert, CheckDeny, CheckPermitOnly and CheckDemand 
        introduced in 2.0.
        * PermissionSet.cs: Fixed IsEmpty using documentation from 2.0 beta 1.
        Implemented immediate (i.e. no stack walk) caller demand (CAS and 
        non-CAS) required for LinkDemand and InheritanceDemand. Implemented
        Assert, Deny and PermitOnly using CodeAccessPermission new methods.
        Re-implement Demand to separate CAS and non-CAS permissions.
        * SecurityManager.cs: Added new private static methods that will 
        either be called by the JIT (linkdemand), runtime (inheritancedemand)
        or by code emitted by the JIT (demand, assert, deny and permitonly).

2004-10-15  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityException.cs: Provide more details when a security exception
        is raised (to help debugging).

2004-09-02  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionSet.cs: Updated to match latest unit tests, i.e. match
        Fx 1.1 on NET_1_1 and Fx 2.0 (beta 1) in NET_2_0.
        * SecurityElement.cs: FromString is now internal before NET_2_0.

2004-09-01  Sebastien Pouliot  <sebastien@ximian.com>

        * NamedPermissionSet.cs: FromXml now calls base class instead of an
        internal method of PermissionSet. This should allow class to inherit
        from NamedPermissionSet properly.
        * PermissionSet.cs: Added an internal PolicyLevel property to allow
        policy file class name resolution. Fixed IsEmpty to return true if
        the list contains "empty" permissions. Fixed Copy to copy permissions
        even for unrestricted sets (again because of IUnrestrictedPermission).
        * SecurityManager.cs: Fixed Resolve(Evidence) because permission 
        classes Intersect methods can either return null or an empty 
        PermissionSet.  Fixed ResolvePolicy(Evidence[]) for null (NET_2_0).

2004-08-31  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionSet.cs: Fixed RemovePermission and Intersect (due to typos
        in unit tests). Fixed SetPermission (null).

2004-08-30  Sebastien Pouliot  <sebastien@ximian.com>

        * NamedPermissionSet.cs: Fixed Description in copies, GetHashCode and
        Equals (for NET_2_0). Fixed handling of null Name when deserialized 
        from XML.
        * PermissionSet.cs: AddPermission now unions permissions of the same
        type. CopyTo throw (most) exceptions only if there are items in the
        set. Implemented Demand (but without support for Assert, Deny and 
        PermitOnly). Fixed deserialized from XML when no class is specified.
        Started implementation of ConvertPermissionSet (error cases). Fixed
        Intersect to be compatible (including bugs like FDBK14612) with MS.
        RemovePermission now compatible with MS (bug? FDBK14622). Fixed Union
        to work with permissions that do not implement IUnrestrictedPermission.

2004-08-26  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityElement.cs: Fixed the new Copy() in Fx 2.0 as it isn't a 
        deep copy. Throw proper exceptions in FromString (Fx 2.0).
        * SecurityManager.cs: Throw a NullReference exception in 
        SavePolicyLevel as MS won't fix it (FDBK13121).

2004-08-19  Atsushi Enomoto  <atsushi@ximian.com>

        * CodeAccessPermission.cs : csc build fix. Currently mcs has bugs on
          CS0136 error detection (variable identifiers in switch cases share
          the scope).

2004-08-17  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Added common methods to help building all
        Permissions classes in corlib. Most are declared static as they can 
        also help non CodeAccessPermission-derived permissions.

2004-08-12  Sebastien Pouliot  <sebastien@ximian.com>

        * SecurityManager.cs: Change ResolvePolicy to only care about host
        provided evidence to create identity permissions.
        * SecurityContextSwitcher.cs: Added missing [ReliabilityContract] to 
        Undo method.

2004-08-11  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Basic implementation for Demand (without
        full stack trace, i.e. Assert, Deny and PermitOnly aren't considered).
        Added TODO to unimplemented NET_2_0 methods.
        * HostSecurityManager.cs: Added comments (as it looked not implemented
        even to myself).
        * PermissionSet.cs: Fixed Unrestricted when copied. Changed exception
        ordering in Copy (ArgumentNullException couldn't work). Made IsEmpty
        more robust.
        * SecurityManager.cs: Implemented IsGranted using Assembly.Demand. 
        Basic implementation for policy resolution.

2004-08-03  Sebastien Pouliot  <sebastien@ximian.com>

        * PermissionSetCollection.cs: New class in Fx 2.0.
        * SecureString.cs: New class in Fx 2.0. Not yet encrypted.

2004-08-02  Sebastien Pouliot  <sebastien@ximian.com>

        * PolicyTypeLevel.cs: Removed duplicate license.
        * SecurityManager.cs: Moved secuirty demands as attributes (but mcs 
        doesn't seem to encode them properly as they show up in corcompare).
        Implemented IsGranted, ResolvePolicy (but some code is still missing
        in related classes) and SavePolicy/SavePolicyLevel.

2004-07-14  Sebastien Pouliot  <sebastien@ximian.com>

        * CodeAccessPermission.cs: Added CheckAssert, CheckDemand, CheckDeny,
        CheckPermitOnly, Equals and GetHashCode to NET_2_0 profile. Actualized
        TODOs. Removed duplicate license.
        * NamedPermissionSet.cs: Added Equals/GetHashCode to NET_2_0 profile.
        Removed duplicate license.
        * PermissionSet.cs: Added Equals/GetHashCode to NET_2_0 profile. 
        Removed duplicate license.
        * SecurityElement.cs: Added Copy and FromString methods to NET_2_0 
        profile. Removed duplicate license.
        * SecurityException.cs: Added new constructors and properties to 
        NET_2_0 profile. Removed duplicate license.
        * SecurityManager.cs: Added GetZoneAndOrigin and ResolvePolicy to 
        NET_2_0 profile. Removed duplicate license.
        * VerificationException.cs: Implements _Exception for NET_2_0 profile.
        Removed duplicate license.
        * XmlSyntaxException.cs: Implements _Exception for NET_2_0 profile. 
        Removed duplicate license.

2004-07-14  Sebastien Pouliot  <sebastien@ximian.com>

        * HostProtectionException.cs: New class in Fx 2.0.
        * HostSecurityManager.cs: New class in Fx 2.0.
        * HostSecurityManagerFlags.cs: New enum in Fx 2.0.
        * SecurityContext.cs: New class in Fx 2.0.
        * SecurityContextSwitcher.cs: New structure in Fx 2.0.

2004-06-15  Gert Driesen <drieseng@users.sourceforge.net>

        * XmlSyntaxException.cs: added missing serialization ctor
        * SecurityException.cs: fixed typo

2004-03-05  Atsushi Enomoto <atsushi@ximian.com>

        * SecurityElement.cs : ignore prefix; this enables RSA.FromXmlString()
          to allow namespaced elements.

2004-01-27  Sebastien Pouliot  <spouliot@videotron.ca>

        * SecurityElement.cs: Attributes are now kept in an ArrayList (but
        still returned in an Hashtable) so the attributes order can be
        kept like MS implementation (but Hashtable cannot guarantee this).

2004-01-26  Sebastien Pouliot  <spouliot@videotron.ca>

        * NamedPermissionSet.cs: Changed internal constructor 
        NamedPermissionSet (SecurityElement e) to NamedPermissionSet ().
        * PermissionSet.cs: Changed internal constructor 
        PermissionSet (SecurityElement e) to PermissionSet ().

2004-01-24  David Sheldon <dave-mono@earth.li>

       * SecurityElement.cs: Changed indentation in ToString, it seems
        MS indent by 3 spaces, not 4. Also added NewLine to childless 
        elements.

2004-01-24  David Sheldon <dave-mono@earth.li>

       * SecurityElement.cs: Changed newline distribution in ToString.
         Matches MS better.

2004-01-06  Sebastien Pouliot  <spouliot@videotron.ca>

        * CodeAccessPermission.cs: Fixed Demand for custom permissions 
        (permissions that do not implement, the internal, IBuiltInPermission).
        Ref. http://bugzilla.ximian.com/show_bug.cgi?id=52626
        * SecurityException.cs: Fixed ToString() which could, when no 
        PermissionType where specified, throws a NullReferenceException.
        Ref. http://bugzilla.ximian.com/show_bug.cgi?id=52626

2004-01-05  Sebastien Pouliot  <spouliot@videotron.ca>

        * CodeAccessPermission.cs: Fixed Union to match 1.1/1.2 documentation. 
        Simplified ToString to match MS implementation. Added LAMESPEC to 
        Assert, Demand, Deny and PermitOnly as they aren't virtual.
        * NamedPermissionSet.cs: Added internal constructor for PolicyLevel. 
        * PermissionSet.cs: Added internal constructor for PolicyLevel. 
        * SecurityManager.cs: Moved some stuff to PolicyLevel class (e.g. Load).

2004-01-03  Sebastien Pouliot  <spouliot@videotron.ca>

        * SecurityManager.cs: Added some basic stuff to make some security unit
        tests works (mostly when using PolicyHierarchy).

2004-01-02  Sebastien Pouliot  <spouliot@videotron.ca>

        * AllowPartiallyTrustedCallersAttribute.cs: Fixed AttributeUsage using
        1.2 documentation (AllowMultiple=false, Inherited=false)
        * NamedPermissionSet.cs: Changes to match unit tests.
        * PermissionSet.cs: Implemented Copy, Intersect, IsSubsetOf and Union 
        methods. Corrected FromXml.
        * PolicyLevelType.cs: Added missing [Serializable].
        * SecurityElement.cs: Fixed constructor to match unit tests.

        documentation (AllowMultiple=true, Inherited=false)

2003-06-29  Sebastien Pouliot  <spouliot@videotron.ca>

        * PermissionSet.cs: Added missing "virtual" to Count, IsSynchronized 
        and SyncRoot.

2003-06-29  Nick Drochak  <ndrochak@gol.com>

        * NamedPermissionSet.cs : Fix buglet/typo/thinko. Thank you unit tests.

2003-06-28  Sebastien Pouliot  <spouliot@videotron.ca>

        documentation (present in monodoc). Added missing MonoTODO attrs.
        * NamedPermissionSet.cs : Changed some code from result of unit 
        tests. Updated MonoTODO attributes.

        from original 1.0 documentation (but inclufed in framework 1.0)

2002-06-10  Duncan Mak  <duncan@ximian.com>

        * IEvidenceFactory.cs (Evidence): Added missing method.
        
        * SuppressUnmanagedCodeSecurityAttribute.cs:
