Re: [Mono-list] Binary serialization
I've attached a document that describes the format. There are some gaps in some tables of codes, so if you find a meaning for the missing codes, please contact me and I'll update the document. Is it possible to check the document in CVS as well? Yes. In which folder should it be added? Another difference is how primitive types are serialized. I've noticed that MS uses the codes of the enum TypeCode to identify primitive types. I did the same, but the codes of mono's TypeCode enum are different, so the formatter gets confused when reading values of an object serialized with MS runtime. I've also seen that decimal values are serialized using a different format. However, this should be easy to solve. This seems like a bug in our runtime. The TypeCode enumeration should in principle have the same values. If it does not, that is our mistake. Do you know which values are wrong? (Or all of it?) I think most of them are wrong. I'll correct them and I'll send a patch. Lluis. ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list

RE: [Mono-list] Binary serialization
The values the binary serializer uses is not the same, the serializer uses a own enum.

You are right! The enum is ok. It seems that MS .NET does not use TypeCode values to encode the primitive types, as I assumed. In may initial tests I used ints and chars, and casually those types are encoded using its TypeCode value, but it is not true for the rest of the primitive types. I'll correct it.

Re: [Mono-list] Binary serialization
Microsoft continues to amaze. I bet that the values are similar to DCOM stuff.

I suppose those are enum(s) in System.Runtime.Serialization.Formatters, InternalPrimitiveTypeE etc? They were available in the alpha version of the ECMA specs file, but were removed lately.

Re: [Mono-list] Binary serialization
Hi, these are really excellent news :-) I was already waiting for a working serialization support because I want to use it in the debugger to allow people to save their breakpoint settings etc. to disk. -- Martin Baulig [EMAIL PROTECTED] [EMAIL PROTECTED] ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list

Re: [Mono-list] Binary serialization
Hello Lluis, I've just commited the implementation of BinaryFormatter and other support classes. Now Mono has support for binary serialization!! Your documentation work is amazing! The research you have done is amazing. I will comment later on as well. I've attached a document that describes the format. There are some gaps in some tables of codes, so if you find a meaning for the missing codes, please contact me and I'll update the document. Is it possible to check the document in CVS as well? However, it does not mean that mono serialization is fully compatible with microsoft's runtime. Although the format is the same, objects may have a different internal structure. For example, mono's ArrayList stores elements in an object array named dataArray, while in MS runtime, it is named _items. An ArrayList serialized using mono is currently not deserializable with MS and vice-versa. I think it happens the same with many other classes, and changing all of them may be a lot of work. If it is just a matter of the fields having compatible names, it might be worth just changing the names in our implementation. It would be more difficult if we need more fields to be serialized though. We should try things one at a time, and see how far we can get. Another difference is how primitive types are serialized. I've noticed that MS uses the codes of the enum TypeCode to identify primitive types. I did the same, but the codes of mono's TypeCode enum are different, so the formatter gets confused when reading values of an object serialized with MS runtime. I've also seen that decimal values are serialized using a different format. However, this should be easy to solve. This seems like a bug in our runtime. The TypeCode enumeration should in principle have the same values. If it does not, that is our mistake. Do you know which values are wrong? (Or all of it?) Now, I'll try to plug this into Remoting ;-) Excellent work Lluis, excellent. Miguel ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list
