[Mono-dev] compilation error in building mono, cygwin
Hi All I ran into a compilation error when building mono in cygwin. The steps I did are: 1) remove all gcc 4.x stuff 2) run autogen.sh CFLAGS=-g -O0 CXXFLAGS=-g -O0 3) make Then error happened: mono-semaphore.c:37: error: storage size of 'ts' isn't known The statement for this error in source file is TIMESPEC ts, copy; And before this location, there is type declaration for TIMESPEC controlled by HAVE_SEMAPHORE_H, which declared in Config.h So I think there might be config error, any help?

[Mono-dev] System.Diagnostics.Process.Start() crashes when trying to allocate more than 255 processes
Dear all,
my linux application needs to start a big number (400) of processes. Each
process is a mono application.
I found the when trying to run more then 255 processes the runtime generates an
exception.
The problem does NOT arise when executing other processes, like e.g. bash.
Example
The following two executables classes are a simple proof of concept.
Just compile the second class and put in into the /tmp folder
MAIN PROGRAM
using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;
namespace CrashTester
{
class Program
{
static void Main(string[] args)
{
///In the real application this dictionary
/// contains useful data. When a process dies,
/// it can be started again with the same input parameters
try
{
for (int i = 0; i 260; i++)
{
Console.Error.WriteLine(STARTING PROCESS:
+(i+1).ToString());
ProcessStartInfo startinfo = new ProcessStartInfo();
startinfo.FileName = /usr/local/bin/mono;
startinfo.Arguments = /tmp/ToCrash.exe +(i+1).ToString();
startinfo.UseShellExecute = false;
startinfo.RedirectStandardError = false;
startinfo.RedirectStandardOutput = false;
Process p = new Process();
p.StartInfo = startinfo;
p.Start();
}
}
catch (Exception ex)
{
Console.Error.WriteLine(ex.Message);
Console.Error.WriteLine(ERROR IN START PROCESS!);
}
Console.ReadKey();
}
}
}
CHILD PROCESSES

{
class Program
{
static void Main(string[] args)
{
if((args!=null)amp;amp;(args.Length0))
{
Console.WriteLine(args[0]);
}
Console.ReadLine();
}
}

Hi, There are two reasons I chose to use Mono.Debugging: 1) Expression evaluation. 2) Nicer interface for VM events (all the socket stuff is abstracted away).

I will look into this some more when I get a chance but I created a sample Hello World program where the problem would happen. So I am not completely on board with the idea that this might actually solve the problem I am running into. I partly believe that it has something to do with how I am building mono and was hoping that someone would have seen this and said: you built the package wrong and step # was where you made a mistake.

Re: [Mono-dev] I: Re: System.Diagnostics.Process.Start() crashes when trying to allocate more than 255 processes
Might it have to do with the fact that Mono only allows 256 shared handles? See _WAPI_HANDLE_INITIAL_COUNT in wapi-private.h and the /* FIXME: grow the arrays */ in handles.c _wapi_handle_real_new(). We ran into a problem like this on a build box that exec'd a lot of processes but we worked around it by using GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); to clean up the handles.
