[Mono-list] Fatal error when running a simple application under Mono

How did you open the port?
In linux you must use "/dev/ttyS0" as port name:
-
System.IO.Ports.SerialPort serialport = new
System.IO.Ports.SerialPort("/dev/ttyS0",
br,
System.IO.Ports.Parity.None,
8,
System.IO.Ports.StopBits.One);

[Mono-list] ADO.NET 2.0 and SqlClient
Can anyone give the status of SQLClient development? The MS-SQL/SQLClient page ( http://mono-project.com/SQLClient http://mono-project.com/SQLClient ), under the "action plan" section, lists: - Add support for ADO.NET 2.0 Does that mean ADO.NET 2.0 is not supported with the current implementation of System.Data.SqlClient?

[Mono-list] ODBC troubles when upgrading from 1.9.1
I was hoping someone might be able to help me solve this problem. I have no troubles running the DBTest app when I have mono 1.9.1 installed. However, when I upgrade to 2.2 or even 2.4 the app is no longer able to connect and execute. At first I received an error that looked like a total garbage japanese character string but when I replaced the System.Data.dll with the 1.9.1 version the error message coming out is connection timeout. I have a C program that runs fine and can connect to the datasource so I know it isn't a connection issue. There is just some difference after 1.9.1. Is there any UNICODE changes that might start causing this? If anyone has any ideas of something I can try to solve this I would surely appreciate it. -- View this message in context: http://www.nabble.com/ODBC-troubles-when-upgrading-from-1.9.1-tp22190969p22190969.html Sent from the Mono - General mailing list archive at Nabble.com. ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

Some more research points to the garbage collector. It appears the GC suspends all threads while it is running. Two facts indicate that this is the case: 1. the threads appear to be suspended for the 10% that they are idle; and 2. the amount of time the threads are idle corresponds exactly to the amount of time spent in the GC in the other threads. This is a huge problem for me. It essentially means that any code that is hard on the GC will diminish the ability of the process to run multiple threads. Could anyone confirm whether this is the case? And if so, is there anything I can do to alleviate the problem? -- View this message in context: http://www.nabble.com/Multiple-threads-slower-than-multiple-processes--tp22177940p22179952.html Sent from the Mono - General mailing list archive at Nabble.com. ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
[Mono-list] Multiple threads slower than multiple processes?
I'm trying to research some threading issues. I've created a simple application that does word count on a file. That application can create multiple threads to do multiple word counts in parallel. There is no communication between the threads; it's just running the exact same thing multiple times at once. I'm running that application against a randomly generated 2GB file. If I run it with 1 thread, this takes about 205 seconds and I'm seeing 100% CPU usage. If I run two instances of the application simultaneously on the same system it takes 205 seconds for each, and I'm seeing 200% CPU (100% for each process). However, when I use two threads in the same process (which does exactly the same thing as just running two instances of the application).It takes 290 seconds, a whopping 40% slower! CPU usage is only about 180%, 90% per thread, and the CPU time consumed by each thread is also more than the CPU time consumed by the single-thread process. This strikes me as extremely weird, and is very worrying for what I'm using Mono for. Is there anyone who can shed some more light on the situation? Here's the program I'm using: http://www.nabble.com/file/p22177940/WordCountTest.cs WordCountTest.cs The system I'm testing this on has two Xeon E5410 quad core CPUs (so 8 cores total in the system). It's running Debian, kernel 2.6.18-6-amd64. Mono 2.2, compiled from the source tarball. Any help would be immensely appreciated. -- View this message in context: http://www.nabble.com/Multiple-threads-slower-than-multiple-processes--tp22177940p22177940.html Sent from the Mono - General mailing list archive at Nabble.com. ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
[Mono-list] Conversation Problem in BinaryReader.ReadInt16 & BinaryReader.ReadByte
Hi,
I'd like to report a but, however I am not quite sure about it because I am
not yet coding that long in Mono. In addition I am pretty new to
networkcoding. Basicly, the following code does not what I expect it to do:
BinaryReader r = new BinaryReader();
byte[] data = {0,0,1,68};
int cnt=0;
while(cnt<4) {
data[cnt]=r.ReadByte();
Console.Write("|{0}",data[cnt++]);
}
Bytestream => Single Output
byte[] data = {0,0,1,68}; => |0|0|0|68
byte[] data = {0,0,1,128}; => |0|0|0|128
...
As you can see, I am missing a "1" regularly. I cant really explain that.
You can follow the Inputstream with Wireshark, so you can be sure about the
source.
In addition, exactly the same happens if you try to read the stream with
r.ReadInt16. Strange.
Did anyone encounter that kind of problem before? I hope it is not related
to any kind of stupidity :-P
PS: Running OpenSuse 11.1 x86_64 with Mono 2.0.1 from official repositories.
Thanks in advance,
Jenzo

Namely, just before AppDomain.Unload is called, the dynamic base directory (where the .dll and code files created while compiling the .as?x are kept) is cleared which may, under certain time conditions, cause the build manger (and possibly other code) to fail because the files it expected to find are no longer there. The commits to svn trunk, revision 128602, and to the 2.4 branch, revision 128603 should fix that. best regards, marek signature.asc Description: This is a digitally signed message part ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
[Mono-list] Unstable XSP 2.4 RC1
Hello, We have several applications running on mono on a beta stage. We recently migrated from win to mono and we have the following setup: » nginx + mono fastcgi server » only one instance of fastcgi-mono-server2 but with several applications (4) >From our current experience we noticed that when deploying, fastcgi-mono-server2 becomes unstable and/or crashes. So at this moment every time we deploy something we also restart fastcgi-mono-server2. This is inconvenient but we get ok with it. The other problem is that without any apparent reason, mono starts throwing errors that we don't understand. For example, this page: http://manual.orionsbelt.eu/en/Battles/BattleConcepts.aspx When we restart mono it displays ok. After some time it may display an error. I copied the error to here: http://manual.orionsbelt.eu/en/Battles/BattleConcepts.Error.aspx It isn't only this page, this is an example. However, it seams to be only with this application. After having this error for the first time we start to get it on several pages, but if we restart fastcgi-mono-server2 it starts to work ok. After some time the error comes again. Is there anything else I can do to help fixing this? I have gathered two related exceptions from our logs: - ERROR -- System.Web.Compilation.CompilationException: CS0006: cannot find metadata file `/tmp/root-temp-aspnet-0/6f3f8f0/App_global.asax.f105942.dll' at System.Web.Compilation.AssemblyBuilder.BuildAssembly (System.Web.VirtualPath virtualPath, System.CodeDom.Compiler.CompilerParameters options) [0x0] at System.Web.Compilation.AssemblyBuilder.BuildAssembly (System.Web.VirtualPath virtualPath) [0x0] at System.Web.Compilation.BuildManager.GenerateAssembly (System.Web.Compilation.AssemblyBuilder abuilder, System.Collections.Generic.List`1 buildItems, System.Web.VirtualPath virtualPath, BuildKind buildKind) [0x0] at System.Web.Compilation.BuildManager.BuildAssembly (System.Web.VirtualPath virtualPath) [0x0] at System.Web.Compilation.BuildManager.GetCompiledType (System.String virtualPath) [0x0] at System.Web.Compilation.BuildManager.CreateInstanceFromVirtualPath (System.String virtualPath, System.Type requiredBaseType) [0x0] at System.Web.UI.PageParser.GetCompiledPageInstance (System.String virtualPath, System.String inputFile, System.Web.HttpContext context) [0x0] at System.Web.UI.PageHandlerFactory.GetHandler (System.Web.HttpContext context, System.String requestType, System.String url, System.String path) [0x0] at System.Web.HttpApplication.GetHandler (System.Web.HttpContext context, System.String url, Boolean ignoreContextHandler) [0x0] at System.Web.HttpApplication.GetHandler (System.Web.HttpContext context, System.String url) [0x0] at System.Web.HttpApplication+c__Iterator2.MoveNext () [0x0] - ERROR -- System.Web.Compilation.CompilationException: : at System.IO.Directory.GetCurrentDirectory () [0x0] at System.Web.Compilation.AssemblyBuilder.BuildAssembly (System.Web.VirtualPath virtualPath, System.CodeDom.Compiler.CompilerParameters options) [0x0] at System.Web.Compilation.AssemblyBuilder.BuildAssembly (System.Web.VirtualPath virtualPath) [0x0] at System.Web.Compilation.BuildManager.GenerateAssembly (System.Web.Compilation.AssemblyBuilder abuilder, System.Collections.Generic.List`1 buildItems, System.Web.VirtualPath virtualPath, BuildKind buildKind) [0x0] at System.Web.Compilation.BuildManager.BuildAssembly (System.Web.VirtualPath virtualPath) [0x0] at System.Web.Compilation.BuildManager.GetCompiledType (System.String virtualPath) [0x0] at System.Web.Compilation.BuildManager.CreateInstanceFromVirtualPath (System.String virtualPath, System.Type requiredBaseType) [0x0] at System.Web.UI.PageParser.GetCompiledPageInstance (System.String virtualPath, System.String inputFile, System.Web.HttpContext context) [0x0] at System.Web.UI.PageHandlerFactory.GetHandler (System.Web.HttpContext context, System.String requestType, System.String url, System.String path) [0x0] at System.Web.HttpApplication.GetHandler (System.Web.HttpContext context, System.String url, Boolean ignoreContextHandler) [0x0] at System.Web.HttpApplication.GetHandler (System.Web.HttpContext context, System.String url) [0x0] at System.Web.HttpApplication+c__Iterator2.MoveNext () [0x0] -- -- Pedro Santos Home - http://psantos.zi-yu.com Work - http://www.pdmfc.com The future - http://www.orionsbelt.eu ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
