[Mono-list] Question about XML-RPC.Net (CookComputing)

[Matthias Kestenholz]

Hi everyone,


I've been struggling with a bug (?) either in the WordPress xmlrpc
server or the CookComputing XML-RPC library for .NET

I have put up a .zip archive[1] on my webhost to demonstrate the problem
I'm having; the password has been changed.


When I try to use metaWeblog.getRecentPosts I get the following error:

$ ./rpctest.exe
Unhandled Exception: CookComputing.XmlRpc.XmlRpcTypeMismatchException:
response contains int value where boolean expected [response : array
mapped to type Post[] : element 0 : struct mapped to type Post : member
mt_allow_comments mapped to type Boolean]
[...]


Modifying MetaWeblogAPI.cs and recompiling doesn't really help:


$ diff MetaWeblogAPI-modified.cs MetaWeblogAPI.cs
49,51c49,51
<     public int mt_allow_comments;
<     public int mt_allow_pings;
<     public int mt_convert_breaks;
---
>     public bool mt_allow_comments;
>     public bool mt_allow_pings;
>     public bool mt_convert_breaks;


$ ./rpctest2.exe
*** glibc detected *** free(): invalid next size (fast): 0x084818d8 ***

The error happens somewhere inside the proxy.getRecentPosts(...) call.

The backtrace I get from gdb doesn't really help since I have no
debugging symbols (or I do not know how to find them; I am using mono
from Debian Unstable)

The only thing I see is that the backtrace is 1109 calls deep...



Thanks for any help or tips,
 - Matthias
