Re: [Mono-dev] status of System.Messaging in Mono
Hi, I am actively working on implementing System.Messaging for Mono using RabbitMQ as a messaging bus implementation, which should be included in the latest builds. It should be considered as alpha at the moment. I am really in need of active users to help find bugs and give me an idea of which features are the most important. Most of the basic messaging features are implemented, but a caveat is that MS's System.Messaging library makes some assumptions about how a messaging bus should work, so some of the more esoteric features can't be supported. To try out our implementation you will need the following dlls from the mono build: System.Messaging.dll Mono.Messaging.dll Mono.Messaging.RabbitMQ.dll RabbitMQ.Client.dll You will need to install RabbitMQ from (http://www.rabbitmq.com), it's Free and Open Source and a decent messaging bus, theory it should work with QPid or OpenAMQ, but hasn't been tested. You will need to make sure that you have the following environment variable set: MONO_MESSAGING_PROVIDER=Mono.Messaging.RabbitMQ.RabbitMQMessagingProvider,Mono.Messaging.RabbitMQ If anything doesn't work, start raising bugs (https://bugzilla.novell.com/), this is the best way to make sure Mono has a decent Messaging implementation.

Re: [Mono-dev] Memory usage on Mono remoting
Hi Gonzalo, Testing PlasticSCM under really heavy load (hundreds of clients against a single server delivering hundreds of Gb over the network). So no profiling... Comparing the same code, the same hardware and the same test under Linux and Windows. On Windows we run under .NET, and the test passes successfully. Dick (in CC) is looking into GC problems. System.Web uses unmanaged chunks of memory together with an unmanaged memory based stream. That's what I need. Can you point me to the right class? It's HttpResponseStream.cs all the *Bucket classes that then use an IntPtrStream. I still don't think that allocating MemoryStream (256 bytes by default) is hurting that bad. Considering Boehm GC seems to have really hard times releasing memory and we're delivering GBs of data... it could be. I'm not 100% sure, but it seems reusing buffers could be a very good idea. A wild guess is that the BufferedStream wrapping the NetworkStream is allocating much more memory (4kB by default). But if the code is rewritten following what xsp does, this should not be a problem any more. Ok, I'm not familiar with xsp, I'll take a look. I've just noticed that you use send from libc instead of the socket functions... I guess it is due to performance reasons, right? Also, you mentioned in a previous email that the TcpChannel should be changed so it uses Asynch sockets. I've seen you use AsyncCallBack on XSP. My question is: I guess AsynchCallback will use a thread underneath, won't it? If so: what's the advantage over launching threads to accept calls? You mentioned it is better to use the default ThreadPool instead of the internal one in the TcpChannel, why is it going to be better?

gedit is a GTK application. Do you have any (GUI) mono-based
applications running on that box ? if so which ones ?
FYI: this is on RHEL5.3 64 bit.

Hello Jon,
The exception from your previous email* shows the problem:
[r...@localhost BTOAD]# mono RMScreenShot.exe test.jpg
BTOStudio RM Client ScreenShot Utility
ERROR Fatal Error: System.NotImplementedException: 0bbp
depth not
supported.
So for some reason (is X running? remote access??) the current visual
returns 0bbp which is unusable to create a screenshot.
Are you able to run GUI (e.g. SWF) apps from your terminal session ?

On Tue, 2009-07-14 at 11:12 +0200, pablosantosl...@terra.es wrote: Hi Gonzalo, Testing PlasticSCM under really heavy load (hundreds of clients against a single server delivering hundreds of Gb over the network). So no profiling... Comparing the same code, the same hardware and the same test under Linux and Windows. On Windows we run under .NET, and the test passes successfully. Oh, when I said profiling I meant the mono --profile=stat or similar that can tell you what and where is being allocated. [...] It's HttpResponseStream.cs all the *Bucket classes that then use an IntPtrStream. I still don't think that allocating MemoryStream (256 bytes by default) is hurting that bad. Considering Boehm GC seems to have really hard times releasing memory and we're delivering GBs of data... it could be. Delivering GBs of data and having hundreds of connections should not be a problem. Years ago, when testing iFolder under those conditions everything worked just fine. But it was mod-mono-server/apache. I'm not 100% sure, but it seems reusing buffers could be a very good idea. Xsp does it too and it's much better than allocating 32kB for every request every time. A wild guess is that the BufferedStream wrapping the NetworkStream is allocating much more memory (4kB by default). But if the code is rewritten following what xsp does, this should not be a problem any more. Ok, I'm not familiar with xsp, I'll take a look. I've just noticed that you use send from libc instead of the socket functions... I guess it is due to performance reasons, right? That's because I wanted to use the TCP_CORK option to avoid sending headers and the beginning of the content in separate packets. Also, you mentioned in a previous email that the TcpChannel should be changed so it uses Asynch sockets. I've seen you use AsyncCallBack on XSP. My question is: I guess AsynchCallback will use a thread underneath, won't it? If so: what's the advantage over launching threads to accept calls? Your guess is wrong. Those asynchronous calls from Socket are treated as if they were a WorkItem for a ThreadPool, only that when they are made, the socket is added to an epoll fd (if you're on linux with support for epoll). And when there's an event in the socket, there's a dedicated IO threadpool to take care of reading/writing data and invoking the callbacks. The advantages: if you have 10k connections, you don't need 10k threads, threads are reused (no creation overhead), ... You mentioned it is better to use the default ThreadPool instead of the internal one in the TcpChannel, why is it going to be better? Coupled with asynchronous I/O, it will make better use of the resources available. There's no need to create 100 threads for 100 client or having 1 threadpool thread blocking on a socket asynchronous operation,... Also, if you're thinking of reusing buffers, this helps too, as the number of buffers will be bound to the maximum number of threads in the threadpool, ... -Gonzalo ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

Re: [Mono-dev] sending smtp email under SSL
Try setting the certificate validation callback.
If you're running mono from HEAD (if you don't know what this is, you
are not):
---
// This will trust *any* certificate
ServicePointManager.ServerCertificateValidationCallback +=
delegate(object sender, X509Certificate certificate, X509Chain
chain, SslPolicyErrors sslPolicyErrors)
{
return true;
}
-
If you're running mono 2.4.2.1 or earlier check out
http://www.mono-project.com/UsingTrustedRootsRespectfully and here's the
sample:
public class NoCheckCertificatePolicy : ICertificatePolicy {
public bool CheckValidationResult (ServicePoint a, X509Certificate
b, WebRequest c, int d)
{
return true;
}
}
...
ServicePointManager.CertificatePolicy = new NoCheckCertificatePolicy ();

[Mono-dev] Performance of TextWriter.ReadToEnd()
I'm playing around with some of the language shootout game benchmarks
at http://shootout.alioth.debian.org,
and I noticed a striking performance issue;
I'm testing on mono 2.4 build 6 / vista64 vs .NET 3.5 sp1. Test code:
static void Main() {
var sequence = Console.In.ReadToEnd();
Console.WriteLine(sequence.Length);
}
test input is a 50MB file.
results.
$ time ./test.exe ../fasta5M.in.txt
real0m1.352s
user0m0.015s
sys 0m0.000s
$ time mono test.exe ../fasta5M.in.txt
real0m18.154s
user0m0.015s
sys 0m0.000s
I see the ReadToEnd() is implemented along the lines of
char[] buffer;
while(Read(buffer) 0)
stringbuilder.append(buffer)
Just as a rudimentarytest using a temp string instead of char[]:
string buffer;
while((buffer = ReadLine()) != null)
stringbuilder.Append(buffer)
is much faster (~10x, similar to the .NET performance), but I'd
imagine this generates more garbage.
not being familiar with the mono codebase, I wasn't sure if the
problem was with StreamReader.Read(char[],int,int) or with
StringBuilder.Append(char[],int,int).
Can anyone shed some insight on this problem?

[Mono-dev] library vs module
Another one of those VS hides the details questions: I'm trying to build a library from A.cs and B.cs, where B.cs uses types from A.cs. It looks like I want to build A.cs to a module, then somehow build the library from B.cs and the A.netmodule, but I can't seem to figure out the gmcs command line syntax. (I can also imagine that I might need C.cs, where C.cs uses type from both B.cs and A.cs ) Anyhow, can some kind soul throw me a tip? ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

Re: [Mono-dev] library vs module
Thanks - someone sent me that privately, and it did the trick. Perhaps `gmcs --help` could explain this better. It gave me the strong impression that all options came before all file names. -Original Message- From: Stefanos A.

That must be a Mono on windows issue. I tried this:
gonz...@laptop:/tmp$ ls -l output2 output3
-rw-r--r-- 1 gonzalo gonzalo 5132004 2009-07-14 20:06 output2
-rw-r--r-- 1 gonzalo gonzalo 596 2009-07-14 20:07 output3
gonz...@laptop:/tmp$ time -p mono rl.exe output2
5132004
real 0.43
user 0.36
sys 0.05
gonz...@laptop:/tmp$ time -p mono rl.exe output3
596
real 0.41
user 0.35
sys 0.08
---
output2 has ~800k lines with a number.
output3 is almost the same but with everything in one single line.
