[Mono-list] Configuration.SectionGroups type cast problem

[Danny Gorton]

Hello all.  I searched the list archives (using google) and couldn't find
anything related to this issue.

My environment is:

Linux raspberrypi 3.12.35+ #730 PREEMPT Fri Dec 19 18:31:24 GMT 2014 armv6l
GNU/Linux and Mono JIT compiler version 3.2.8 (Debian 3.2.8+dfsg-4+rpi1).
I develop on Windows with VS.NET and automate builds on Linux/Mono and test
on Windows and Raspbian (ARM) and Ubuntu.  Most of the time it *just
works*, but every once in a while I run into some weird differences between
.NET and Mono.

My product is a daemon with ServiceStack 3.9.x embedded to provide web
services.  I have features for altering server configuration options
through a web UI.  When that web service is called it looks for specific
ConfigurationSection instances (some custom, some standard) by iterating
the configuration hierarchy, through the SectionGroups
(ConfigurationSectionGroupCollection) on downward until it finds a match.
Here is one example:

foreach (Config.ConfigurationSectionGroup group in
_config.SectionGroups)
{
..
}

In this code _config is a System.Configuration.Configuration instance and
this code works on .NET (Windows 7), but breaks on Mono on the foreach line
with:

System.InvalidCastException: Cannot cast from source type to destination
type.

For some reason the contents of SectionGroups don't seem to be
ConfigurationSectionGroup objects. So I put in some debug logging like this:

if (_log.IsDebugEnabled)
{
StringBuilder sb = new StringBuilder();
sb.AppendLine(string.Format("Configuration has [{0}]
section groups:", _config.SectionGroups.Count));
foreach(object o in _config.SectionGroups)
{
sb.AppendLine(string.Format("\tSectionGroup of type:
[{0}] is [{1}]", o.GetType().FullName, o));
}
_log.Debug(sb.ToString());
}

The output on .NET shows the right types (don't have an example handy right
now).  The output on Mono looks like:

2015-08-23 21:59:14,945 [Threadpool worker] DEBUG raspberrypi
ConfigurationHandler.getSection (line 0) - Configuration has [5] section
groups:
SectionGroup of type: [System.String] is [system.web]
SectionGroup of type: [System.String] is [system.net]
SectionGroup of type: [System.String] is [system.serviceModel]
SectionGroup of type: [System.String] is [system.transactions]
SectionGroup of type: [System.String] is [apac]

As you can see, the types are string and the values are the names of the
section groups in question.  I've looked at the code history for
ConfiguratoinSectionGroupCollection and Configuration.SectionGroups and I
don't see where either was ever written to store just simple strings,
though I may be missing something.

My  element is:
  

  
  

  


  
  
  

Anyone have any idea why this would be happening?

and is working):

I'm thinking that this could be a permissions error somewhere, but

Re: [Mono-list] string equals method

[Danny]

The mono question is easy to answer by looking at their sources.  The 
.NET question is easy to answer by using Reflector/ILSpy/or similar.  I 
won't answer the .NET question here b/c I don't want to cause any IP 
issues with posting .NET internal information on a mono site.

The thing I'd like to know:  Ordinal string comparison tends to be an
expensive thing to do.  This can be skipped under certain circumstances,
such as, if ReferenceEquals returns true, or if the two string length's
are different.

Can anybody authoritatively say, under the hood, that .Net or mono
actually do this sort of acceleration in the string.Equals() method?

Re: [Mono-list] Help debugging program failing randomly

[Danny]

(Sent this earlier, but it didn't post to the list)
Thanks to Ian and Alan for the replies.  I have done some further 
elimination (by removing runtime components) and I don't think it is the 
new board interface causing this.  I think it is another component, that 
isn't quite as new, but I had forgotten is new in this context (ubuntu 
server).  This component periodically uses a graphing library (ZedGraph) 
to generate line graphs from the data collected from the input boards. 
I have included the entire capture of the stack trace that mono sends to 
stdout.  Note that this is a capture of the console, not a log file or 
core dump (which I'd like to know how to get from monoservice2), so it 
includes system status messages from my code as well - I left them in 
for context, whether it matters or not.


http://pastebin.com/kQFF4TUB

I currently have a test running that eliminates this graphing component, 
but includes the new board component, and it seems promising so far. 
I'll feel better after it runs for a week though, since I've had it run 
for almost 5 days before it crashed.


At any rate, if it is this new component and the graphing library
causing this issue, I need figure out how to fix it.  Also, I have used 
ZedGraph for a very long time to generate images like this, but the 
frequency used to be limited to once per day.  Now it can be once per 
minute.  The once/day generation is done in yet another component, so it 
could be the two 'walking' on each other if the underlying code isn't
thread-safe.  I would expect some kind of time correlation if that was 
the case, and I just don't see that.  I have some ideas on how to
serialize all of these operations to a single thread, but I'd need to be 
fairly sure of the problem before I went to the effort to implement that.


If I could get a good bead on what I'm doing that causes this error I
can work around it.

Thanks again for the help,
Danny

[Mono-list] Help debugging program failing randomly

[Danny]

Hello,

I'm having a difficult time with an application I have written.  I 
recently made some changes and I'm having a problem with it failing at 
seemingly random times and locations (within the code), with sigsegv 
errors.  This is a multithreaded plugin-style daemon/service (can be 
launched from CLI) and I recently added a new component to it to poll a 
data acquisition board via USB using FTDI.


Almost all of our integrations like this use a shared library (or DLL on 
Windows) and p/invoke to access hardware.  I have done dozens of these 
integrations over USB without a persistent issue like this.  But still 
at first I suspected this new component, as I had initially thought it 
was trashing RAM because of the problems I had developing the shared library


However, at the same time as I made this addition, I was also (somewhat) 
forced to upgrade our base OS to the latest LTS Ubuntu 12.04 (was on 
10.04).  So unfortunately, I have more than one variable changing at a 
time.  So I confirmed, with a configuration that eliminates the newly 
developed component, that this problem occurs without that running.


That's good and bad, since now it seems likely that the offending code 
is out of my control.  I am hoping to get some information on the 
error(s) I was able to capture, or some advice on how to debug the root 
cause of this problem.


I have a couple of stack traces captured and I'll include what I believe 
is the crucial part of one here.  It's worth noting that not all of the 
stack traces are the same.  It's also worth noting that I have seen 
libgdiplus.so in other traces that I didn't get captured.


I tried setting up a 10.04 machine to test with, but one of our newer 
dependencies (ServiceStack) introduced a class that is not in the 
default mono on that platform, giving a startup error trying to resolve 
the IgnoreDataMemberAttribute class.  So I then got the latest mono set 
up on that machine now, but fear that this will result in the same error 
I am reporting (ie: I believe this to be a mono problem), since it 
should be the same mono framework running there.


Any help is greatly appreciated.

Re: [Mono-list] Cross-platform user settings files

[Danny]

The built-in app.config features work fine cross-platform.  Even custom 
configuration sections and all of that.  Our system uses them 
extensively for system composition (ie: defining which components should 
be started at runtime) on both .NET and Mono.  But that type of setting 
setup is per-application; it doesn't make an ideal per-user 
configuration system unless you create your own construct within it. 
Totally feasible, but probably not what the OP was getting at.

strongly-typed access to all the properties.

Would the solution require setting file access permissions during

Where is the best location on Linux/Mac OSX to store such setting files?

You can add this to your app.config file using the  element and it

The  element is a child of .

You can add this to your app.config file using the  element and it 
will get appended to the system's default set.  An example from my 
system that uses Firebird...

Re: [Mono-list] C# app with makefile n executable

[Danny]

I'm not sure about the makefile, since I never build C# code with make - 
it probably calls in to msc or similar though.

But the 'executable' file is just a bash script that will run the 
compiled EXE using mono on Linux.  It doesn't need an extension, and you 
might name it like your program, without the extension.  Just make sure 
the executable bit is set on that script.

Re: [Mono-list] Difficulty with DllImport in mono - config.AG_Config file is not in load-path.

[Danny]

Without seeing your wrapper code, I'd guess that your DllImport 
statements include the file extension (.dll).  To make the lookup work 
properly on Linux/Mono you either need to exclude the file extension 
(ie: just use 'ag_gui' - both .NET and Mono will resolve this correctly 
if the file is in a proper search path) so the native naming schemes can 
be used on the respective platforms, or use a DllMap in your config file 
to tell mono how to map ag_gui.dll (and others).

Re: [Mono-list] Creating a Daemon un Linux

[Danny]

You want to look into implementing a standard 'Windows' service (using 
the service template is easiest, but since you didn't mention your dev 
environment I can't say how you'd go about it) where you subclass 
ServiceBase and then control it with mono-service or mono-service2 and 
an init.d script.

Last time I did this, a long time ago, I had to piece my solution 
together from information about each of these parts.  But it isn't 
terribly difficult, just kind of obscure at the moment so getting a full 
end-to-end explanation doesn't seem easy.

Re: [Mono-list] C# First port of application to mono

[Danny]

Actually, that *is* right, with some important notes.  Firstly, if your 
p/invoke calls are decorated with the full DLL name (MediaInfoLib.dll) 
then on Linux you must use Mono's dllmap to get it to find your native 
code due to the different naming conventions for shared object libraries.

For native libs that I control the source for and I can decide the 
compiled file names, I always make the 'root' of the names the same and 
p/invoke with just the file name, no extension.  Eg: MyCode.dll becomes 
libMyCode.so on Linux and the p/invoke DllIMport attributes use 'MyCode' 
as the dllName.  This can apply for 3rd party native libs too if their 
libraries are thusly named.  After that, the .NET and mono search 
algorithms work just fine on their respective platforms, as long as the 
native libs are in standard place (/lib, /usr/lib, local dir, system32) 
- see the docs for specific info on those search algorithms.  If not, 
again dllmap is your friend.

[Mono-list] Mono and Dallas/Maxim 1-Wire

[Danny Gorton]

Hello list,

This may be slightly off-topic for the Mono list, but I'm making a
cross-platform product on Windows/Linux using .NET/Mono and have until now
had really good successes with making my components work seamlessly on the
two platforms using the appropriate native libraries and P/Invoke
(DllImport).  Now I'm trying to integrate 1-Wire sensors into the mix and
I'm having trouble finding the code module(s) I need.  It may be due to my
lack of a traditional C background, or whatever.

I just wanted to make a quick poll to see if anyone knows of a
cross-platform version, or at least a dynamic library, of the 1-Wire
interface:  http://www.maxim-ic.com/products/1-wire/software/.  I've looked
at all of these (except Java, which isn't an option) and they seem to be
really geared toward Windows - the .NET components P/Invoke Windows (or CE)
libraries for serial comms.  I don't have enough C-foo to make a dynamic
library out of the public domain component(s), but that is what I intend to
tackle if I can't find that it has already been done.

I *can* make distinct plug-ins for *nix and Windows if necessary, but would
rather not.  At any rate, I need to target Linux first, and at the moment
I'm stuck. So before I dig in to get really dirty I figured I'd ping this
list.  Also, I have noticed owfs (http://owfs.org/), which got me excited
until I realized that it put me in nearly the same boat - no dynamic library
that I can call from C#.

Any and all help is appreciated, even if it poses a way to solving the
problem I haven't mentioned or alluded to.

Thanks in advance,
Danny

Re: [Mono-list] Application port to .Net, including Mono

[Danny]

FWIW, I have used interop on both MS.NET and Mono on Ubuntu with no
problems.  I think you're more likely to run into interop problems due
to the native library signatures than any platform oddities.  Just leave
off the DLL extension in your DllImport declarations and build one
version of the native code for Windows, the other for *nix and deploy
accordingly.  I think there is some weirdness there WRT to MAC (Apple)
OS's file naming, but I've no direct experience there.

As for #2, I'd make an wrapper assembly that is solely responsible for
interoping your native library.  That leaves the web service code
responsible for ONLY web service necessities, and gives you the ability
to host your component in a non-web-service host, such as a Windows
service (daemon) without copying core code around - or having to
refactor later - and the only real worrisome part being managing object
serialization properly, which is no big deal really.

Use interfaces to define your messages and your client side component
becomes a proxy object to the remoted server, web service or otherwise.
With web services you get proxy generation for free based on the WSDL
and with standard remoting you just use the configuration infrastucture
to get your proxy object instance of your interface.  This is more
nuts-n-bolts than WCF, which I never bothered to really learn, but we
use this approach alot and it works well.  Though you have more
components to manage in the long run, it gives you almost complete
control over how you can deploy the service using a once-and-only-once
and separation-of-concerns paradigm.

Hi,

You could have a look at Mono.Addins; or scripting languages like Boo,

afterwards. Works nicely.

[Mono-list] JSON not working when using WebServiceHost (returning XML)

[Danny Haak]

Hi all,

I am trying to implement the example at 
http://www.developmentalmadness.com/2008/05/intro-to-wcf-for-ajax.html (want to 
make a RESTful webservice using JSON). The example is working, but instead of 
JSON, it returns XML. Is this example correct (bit tough to find an easy 
example on the interwebs); or is is it a bug (using Mono 2.4.2.3 at Mac OS X 
10.6)?

Thanks!

[Mono-list] monolinker and web apps

[Danny Waite]

Hi All,

 

We run a platform that has both a mono daemon/console app and a web user 
interface that users mod_mono.

 

Most of the functionilty is contained in the console app and we've successfully 
used linker and mkbundle to create a single binary containing all libs etc.  
Great! I can now remove the mono framework and save some much needed disk space.

 

Then I realised about the web app...!

 

How would I go about running the web app (which is pre-compiled) since the mono 
framework will no longer exist?  Can I link this too?

 

Help, as always, is very much appreciated.

 

Regards,

Danny

Re: [Mono-list] Serial Ports

[Danny Haak]

Hi Glenn,

My experience is that serial ports work using the same code in Windows
and Linux - with the only change being the port name. Does your serial
device need RTS/CTS lines? Are they set right? Is the timeout set
correctly? 

Best regards,
Danny Haak

We have a peice of code that is working without a hitch on windows.
However on Mono (Ubuntu Jaunty; runtime 2.4) We get nothing. No
exceptions, no errors but also its not connecting. Are there any
settings or configuration options, any gotchas that i need to know when
handling Serial ports on Mono on Linux? We have switched our code to use
the ubuntu device name (/dev/ttyS1) and have verified the device exixts
and works on that port, weve tested with PUTTY.

Re: [Mono-list] USB hardware detection using Mono on Linux

[Danny Haak]

Hi,

That seems like a good approach, but on the HAL site it states that "HAL
is in maintenance mode - no new features are added. All future
development focuses on Software/DeviceKit-disks,
Software/DeviceKit-power, NetworkManager, PulseAudio, udev, ... " [1].
Therefore, it seems not a good idea to me to use it in new software.

Best regards,
Danny

I believe you can attach to the system D-BUS and you will receive HAL
events.   <http://www.ndesk.org/DBus_Documentation>

[Mono-list] USB hardware detection using Mono on Linux

[Danny Haak]

Hi all,

I am currently writing a piece of software that needs to detect which
USB devices are attached to the computer. Event-based notifications of
attaching and detaching hardware while the software is running is nice,
but not required.

I first used DeviceKit-Sharp (by Ben Gamari), but when observing a bug
and asking the DeviceKit mailing-list, Kay Sievers answered: "The
DeviceKit daemon is dead and will not run, or be installed on any usual
system. You need to use libudev, or the GUdev to retrieve this
information." This is a pity, because DeviceKit was working nicely,
despite the bug in the daemon.

I can't find any Mono-bindings for libudev, and diving deeper in the
documentation, libudev seems quite low-level and talking to HAL. Looking
for HAL abstractions, I discovered that HAL will be obsolete as well in
the near future. This leaves me completely confused about 'the way to
go' for hardware detection in Mono on Linux. Is there anybody who can
suggest a (sort of) future-proof approach to this?

Thanks, best regards,
Danny Haak

Thanks alot.  Indeed it does look pretty vanilla in term of the remoting

I'd like to second that.  I use the same techniques with good results. 
However, *occasionally* I have problems with my remoting listener 
holding open the TCP socket after shutdown (in which I unregister the 
marshalled object(s)).

If you don't mind me asking, do you do anything specific or special to 
clean up your remoting channel?

Re: [Mono-list] Need High-Level Graphics Library

One of the references found here

Not sure about your requirement in Canvas so it may not meet them; it is 
used as a control in Winforms or WebForms.   It does nice graphs in a 
flexible way and supports zooming, etc.  I use it for both static graphs 
and graphing live data.

I've now pre-compiled my web app using VS2008 and Web Deployment Tool.
 
When I browse to the URL I get:
 
"This is a marker file generated by the precompilation tool".
 
What needs to be done to the apache configuration, ie. which extensions should

I know I'm missing something very silly.

Re: [Mono-list] Remoting Puzzle

[Danny]

Not sure if this helps or not, but I've seen cross-platform remoting 
issues caused by serialization incompatibility - private member names 
differ across implementations so SerializationInfo contains different 
keys.  Could it be that a SerializationException is getting 'eaten' due 
to multi-threading or similar situation?

Re: [Mono-list] cannot find metadata file

[Danny Waite]

Fantastic, thanks Pedro, I'll give that a try!
 
Any other considerations or tips you can add, sounds like you've got things 
working really well for you.

Danny

Re: [Mono-list] cannot find metadata file

[Danny Waite]

Interesting!  Thanks Pedro.  What do you mean by precompile?  I'm using the 
publish function in Visual Studio (gulp) I saw that there is better support for 
that in 2.4 however maybe thats a bad way to do things.

[Mono-list] cannot find metadata file

[Danny Waite]

Hi All,
 
I've been through various mono versions over time and have seen this error 
throughout and it really has been beaten!  It's an ASP.NET web app, quite a 
simple one.  It works well for a while until we get the following error.
 
If we kill the mod-mono-server2.exe process or restart apache, it stops.
 
Could anyone shed any light onto it before I pull my hair out! :-)
 
Best,
Danny

Re: [Mono-list] Dock Panel Control (WinForms) for Mono

[Danny]

I would be very interested in a version of DockPanel with these changes 
made...to the point of helping out as needed.  I very quickly looked at 
DockPanel on Mono and decided to use it in spite of the p/invokes, 
hoping they could be factored out.

I have very little time in the short term, but if I can pitch in with 
some specific tasks or research don't hesitate to let me know.  If this 
isn't done now, I'll eventually have to get to it myself.  Though other 
(more pressing) things currently prevail, and will for some time, it 
would save me lots of time later to help out now.

TIA,
Danny

Re: [Mono-list] FileSystemWatcher on Linux to monitor a remote NTFS share

[Danny]

I think if you use a mount point, the FileSystemWatcher would then be 
unaware of the fact that the directory being watched is in fact on a 
Windows machine (abstraction) and that seems like a logical thing to try 
to me.  The only thing I'm wondering is whether the mount type needed 
(cifs) will support the FileSystemWatcher's needs, which I am not 
familiar with.

Re: [Mono-list] Mono and its limitations

[Danny]

All of the answers so far are right on.  And it's funny that you should 
ask about those specific things because right now that's about ALL my 
application does.  It polls data from COM ports (soon to be USB ports 
too) and stores it in a home-grown XML data store, which makes heavy use 
of streams for file read and write access.  Other than that it also 
provides a client interface via remoting, which is the only part I had 
any portability issues with.

For things such as you mention - port names and file paths - I push them 
out to configuration where the 'platform-specificness' of them doesn't 
matter.

Hope that helps,
Danny

Re: [Mono-list] Mono and its limitations

[Danny]

You English seems pretty OK to me.  To your question (which others may 
be able to answer with greater detail): I've been successfully writing 
code on Windows and running it on Linux (Ubuntu+Mono) for over a year 
now.  It seems that the Mono guys have done a pretty good job at making 
a runtime that is compatible with any CLR assembly - at least those 
produced with current C# and VB compilers.

It stands to reason that they would also produce compatible assemblies 
with their development tools, so the reverse (Running code on Windows FW 
that was created on Linux+Mono) should be true as well.  There have been 
a few small 'gotchas' but overall very easy.

Re: [Mono-list] SoC project idea - PLPlot#

[Danny]

Have you looked at http://zedgraph.org?  I believe it can be used as you 
suggest, and it's all managed so should run on Mono.  I currently have 
only tested it on MS.NET as a UI control, but have need shortly to use 
it as a class library for generating static graphs from within my 
server-side component.  So I'll be vetting that part of it on Linux+Mono 
in the near term.

Re: [Mono-list] Dictionary`2 compatibility

[Danny]

One of the few areas of incompatibility I've had with Mono is binary 
serialization.  It's to be expected given the nature of that beast.

The way I handle it is to implement ISerializable in my code and 
serialize my members myself.  Then all the private names of the members 
stored in the SerializationInfo match on the inbound side.  If you do 
this, check the docs and don't forget the deserializing constructor.

[Mono-list] Compiling AOT

[Danny Waite]

Hi Guys,

 

I'm compiling my libraries AOT for the first time.  I notice the .so file is 
created is of simiar size to the original library so that begs the question, 
does compiling AOT double the footprint needs? (ie. if I compile all the mono 
libraries and my own libraries)

 

Thanks in advance.

[Mono-list] Build .sln from mono/monodevelop

[Danny Waite]

Hi All,
 
I'm trying to build an entire solution (.sln)
 
So far I have done the following:
 
mdtool project-export ./Solution.sln
 
once done I expect to run:
 
mdtool build
 
However the project-export returns:
 
Unknown file format: /root/Xrio.Standalone/Standalone.sln
 
Any ideas anyone?  Maybe its the version of Visual Studio the .sln was created 
from?

Re: [Mono-list] Run C# app on the server

[Danny]

Well, it is confusing - at least until you understand it.  I'd always 
noticed it, but never realized what it was.  At least now I understand 
it and can try to not add undue clutter.  There's nothing more annoying 
when you're in hot pursuit.

Anyway, thanks for the education Sandy.

Re: [Mono-list] [MonoDevelop] webservice debugging question

[Danny]

Isn't that what Cassini is?  I mangled that code some time ago to allow 
it to accept requests from non-local hosts and to serve out SVG.  It was 
a while ago, but I think I got it running on Mono, though don't hold me 
to that one.

I think this post has links to 3 versions of that sample web server:
http://blogs.msdn.com/dmitryr/archive/2006/03/09/548131.aspx

Also not sure about licensing issues; since I was only experimenting 
with it I didn't investigate too far.

[Mono-list] Using Grep

[Danny Waite]

Hi guys,
 
I'm using System.Diagnostic.Process to execute a command and I'd like to pipe 
through grep.
 
If I set proc.StartInfo.Arguments to something like "| grep blah" the 
referenced binary does not understand the command.
 
Has anyone seen this problem before?

[Mono-list] Olive/REST/WCF

[Danny Waite]

Hi All,
 
I'm looking at the possibility of using REST together with mono and wondering 
if anyone has any experience with this.
 
.NET 3.5 provides such functionality using System.ServiceModel.Web however I'm 
unsure if this functionality is implemented in Olive yet.
 
I see there are a number of REST libraries around that might do the trick, but 
before I dive in I want to see if anyone else has been on this path.
 
Any help/comments are appreciated.

[Mono-list] Web Service Extensions in mono 1.9.1

[Danny]

Firstly, I hope this is the right list.  If not please redirect me as 
needed.

I've been searching on the mono site and the 'Tubes in general for a 
couple of days now and can't seem to nail down anything definitive about 
how to get web service extensions working on Ubuntu Linux 8.04.  I've 
seen some posts stating that it's not available on Ubuntu, and others 
stating that it should be in mono 1.9.1, which is what I have.  I 
suspect I'm not knowledgeable enough about it to use the right key words 
- the obvious ones don't help much.

Specifically, I'm trying to consume a web service from JavaScript (using 
Dojo if it matters).  I have it working on Windows under IIS.  When I 
move it to mod_mono under Apache2 on Linux it fails with:

Failed to load httpHandler type 
`System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, 
Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35'

So System.Web.Extensions.dll obviously isn't there, and I could not 
locate it (any version of it) on the machine.

After not being able find any info on that assembly I tried copying the 
one from Windows over to my the web service bin, without much hope, and 
it actually worked, a little.  It would process an HTTPGET request, but 
fails on an HTTPPOST with a NullReferenceException originating down in
WebServiceData:

System.NullReferenceException: Object reference not set to an instance 
of an object
   at System.Web.Script.Services.WebServiceData.GetWebServiceData 
(System.Web.HttpContext context, System.String virtualPath, Boolean 
failIfNoData, Boolean pageMethods) [0x0]
   at System.Web.Script.Services.WebServiceData.GetWebServiceData 
(System.Web.HttpContext context, System.String virtualPath) [0x0]
   at System.Web.Script.Services.RestHandler.CreateHandler 
(System.Web.HttpContext context) [0x0]
   at System.Web.Script.Services.RestHandlerFactory.GetHandler 
(System.Web.HttpContext context, System.String requestType, 
System.String url, System.String pathTranslated) [0x0]
   at System.Web.Script.Services.ScriptHandlerFactory.GetHandler 
(System.Web.HttpContext context, System.String requestType, 
System.String url, System.String pathTranslated) [0x0]
   at System.Web.HttpApplication.GetHandler (System.Web.HttpContext 
context, System.String url) [0x0]
   at System.Web.HttpApplication+<>c__CompilerGenerated2.MoveNext () 
[0x0]

I reflected that assembly and it looks like the only obvious thing that 
might cause this is a null context.  Not sure what might cause that.

It could very well be my web service configuration and/or implementation 
- at this point I'm not sure what to think.  I hacked the thing together 
from bits and pieces of info I found here and there.  I am very familiar 
with web services both server-side and client/proxy, but I'm fairly new 
to mono, mostly I just write apps on Windows and move them to Linux and 
they work (which rocks BTW), and I've never written a web service client 
in JavaScript before.  So I have too many unknowns to be able to deduce 
the solution on my own - but most things point to my mono setup.

However, I know it COULD work, and the current prototype I have on 
Windows kind of proves that.  Can anyone suggest how I might get this 
functionality working in this config?   I need to know if it SHOULD work 
before proceeding further because I must deploy to Linux and will have 
to tackle client-side data updates some other way if it's not possible. 
  More info on specific config settings, et al will be provided ASAP and 
as necessary.

Thanks in advance,
Danny

[Mono-list] Debugging Mono Apps developed on Windows/VStudio

[Danny Waite]

Hi All,
 
I prefer to develop apps on Visual Studio, build them and then SFTP to my Linux 
box to test.  It gets quite tedious when in the final stages of testing because 
you are making small tweaks and have to keep transferring them across.
 
I just wondered what other people were doing in this scenario?  I guess the 
problem is that I'm making a lot of system calls so the code really needs to 
execute on the linux box itself.  Is there any kind of remote debugging 
supported?
 
Thanks in Advance,

Re: [Mono-list] Pash - cross platform PowerShell is out in the wild!Announcement.

[Danny Waite]

Fantastic! I've been waiting for this for a long while now. Great work Igor, 
I'll be playing around with this at the weekend.  I think this project has lots 
of mileage. 


From: Igor Moochnick 
Sent: Monday, April 07, 2008 4:23 PM
To: [EMAIL PROTECTED] ; mono-list@lists.ximian.com 
Subject: [Mono-list] Pash - cross platform PowerShell is out in the 
wild!Announcement.


Pash - http://pash.sourceforge.net/

PowerShell open source cross-platform reimplementation.


About the name
Pash = PoSH (PowerShell) + bash (one of the Unix shells)


Goals
The main goal is to provide a rich shell environment for other operating 
systems as well as to provide a hostable scripting engine for rich 
applications. The user experience should be seamless for people who are used to 
Windows version of PowerShell. The scrips, cmdlets and providers should runs 
AS-IS (if they are not using Windows-specific functionality). The rich 
applications that host PowerShell should run on any other operating system 
AS-IS. Secondary goal: the scripts should run across the machines and different 
OS's seamlesly (but following all the security guidelines).


Environment
The current implementation of Pash is written using pure .Net 2.0. It compiles 
on VS 2008 as well as on Mono. So all the developers can choose the environment 
that fits their needs and preferences. The produced assemblies can be executed 
"right out of the box" on Windows, Linux, Mac (or others) without any 
additional recompilation. Note: for Windows Mobile and Windows CE the produced 
code should be recompiled against the .NET Compact Framework.


Progress
You're welcome to get the source code and contribute to the Pash public effort 
@ http://sourceforge.net/projects/pash. 

~50% of public PowerShell classes defined. 

~40% of framework functionality operational.

[Mono-list] Linux IP Networking Wrapper

[Danny Waite]

Hi All,

I'm about to start to build an help around the Linux "ip" command that is used 
to configure links, tunnels, IP addressing etc. and just wondered if there was 
anything available already, to prevent reinventing the wheel.

This seems like a fairly common requirement but it seems projects like Zeroconf 
do not cover it.

I came across the excellent http://code.google.com/p/sharpknocking/ that 
provides a great wrapper around iptables/netfilter but could see nothing in the 
way of the above.

Because all the various Linux distro's have their own way of configuring the IP 
stack, I guess this would be a really helpful library.

[Mono-list] Forms Authentication

[Danny Waite]

Hi guys,
 
I'm trying to use Forms authentication but am getting strange problems.  I 
understand from a previous port that System.Web relies on System.Windows.Forms 
which I guess then relies on gdiplus.  When I load a page that references the 
 component I get a strange message "Color X is not a valid color."  
If I take out all the colours I then get "System.DllNotFoundException: 
gdiplus.dll".  I dont have this on the system for some reason but I added 
gdiplus.s to /usr/lib and called ldconfig but still get the same.
 
 
Help! is appreciated.

[Mono-list] Finding out the required dependencies

[Danny Waite]

Hi guys,
 
I'm running XSP2 in an embedded system when the disk space is sparse at best.  
How do I find out what libraries my app is running and remove all the rest from 
the GAC?  Is there a quick and easy way to do this.  I tried removing the ones 
I 'know' I am not using like Windows.Forms but seems there are hidden 
references in the dependency chain.
 
Thanks in advance.

Hi Robert,
 
Thanks for that, actually the problem was that I needed #!/bin/sh at the top of 
the script.  I'll move the proc.WaitForExit(). to the end.

[Mono-list] Executing shell scripts from XSP2

[Danny Waite]

Hi guys,
 
I'm having a hard time trying to call a shell script from XSP2, it seems to 
work on somethings and not others.  What is the best way to do this?  I've 
included my code below...
 
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = "/sbin/commit_config";
proc.StartInfo.Arguments = profile;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardOutput = true;
proc.Start();

proc.WaitForExit();
if (verbose)
  Console.WriteLine("result: " + proc.StandardOutput.ReadToEnd());
 
Could this be a permissions problem? When I run the shell script from within 
linux it works perfectly, but when run with within XSP2 the StandardOutput 
gives nothing.
 
Help!
 
Much appreciated,

Hi,

I saw this posting and wanted to reply. I am currently using SusE10.1
and enthousiastic on the YAST capabilities for the first installation.
But I was having some difficulties with the mono-basic package. It had
dependency problems. But installing the package using commandline RPM
there was no trouble at all.

Even updating new packages is quite easy actually.

Hi all,

I have done some small research and I got it working. Actually it is
quite easy;

I can mail how i have done it, perhaps that would be of interest.
perhaps some of you got some more tips on it.

[Mono-list] Howto: Build custom events

[Danny Stolle]

Hi all,

this perhaps sounds really dumb, but i have some trouble writing events
and raising them using C#. i have no trouble on writing classes having
its methods, properties, etc. but when it comes to events, i don't know
how to use them.

programming in VB6, I used Microsoft back then, was easy. you declared
the event you wanted, like: public event StatusOK(string message)
within the class you could raise the event by using: RaiseEvent
: e.g. RaiseEvent StatusOK.

Now I am off VB and using C#. But can somebody please point me out to
some good documentation on how to write custom events for classes and
how to raise them in your apps.

Thanx a lot.

Hi Ruben,

Sorry for the joke .. but perhaps installing from source? Would that be
an option? Or do you really want to install from packages?

Hi Janos,

Thanks for the reply ... I have checked my configurations; check your
Xml manifest. For example for the Monodevelop.MonoQyery:
/usr/monodevelop/AddIns/MonoQuery and open the xml file. The
Extensionpoints are part of the DLL files which are imported as assembly
in the beginning of the file (well I think they are if I think logically
:-) ) ... If the extensionpoint can not be traced, than perhaps the
DLL-files which are imported aren't correctly compiled. You can try by
removing the extensionline (be sure to make a copy of the original first ;-)

Hi,

I don't think I am getting the discussion here. Are you trying to start
MonoDevelop, so you've already installed the software on your computer?
Or are you trying to compile the software in order to install it on your
computer. Because Jeffry implies that it is a compile error, while I am
thinking you've already installed it and that there are errors during
initialization time during startup of the software.

Re: [Mono-list] gtksourceview-sharp / gtksourceview conflict on Fedora Core 3

[Danny Brugman]

Hi Thomas,

I encountered the exact same problem. The conflicting file
is 'vbnet.lang', which contains the syntax highlighting
definitions for the VB.NET language. This is used by 'gedit',
for example.

This file can safely be overridden by the one provided by
the 'gtksourceview-sharp-0.5-1.novell.9.1' package. Just
use the '-f' option of rpm to force an install, and overwrite
the file. It worked for me.

Kind regards,

Danny Brugman

Mono 1.0.6 is dependend on version 2.6 of the Unicode 'libicu' library.
The libicu version supplied in the Fedora Extras repository is
version 3.2. However, the 'DAG APT Repository' supplies version 2.6.
The URL for the DAG repository for your yum.conf is:
  http://dag.freshrpms.net/fedora/$releasever/en/$basearch/dag/
Supposing that you use the example yum.conf from www.fedorafaq.orf:
  http://www.fedorafaq.org/samples/yum.conf
You can issue the following command to install version 2.6 of libicu:
  yum --enablerepo=dag --disablerepo=extras install libicu
If you want to prevent that libicu is updated to version 3.0 with the
next 'yum update', add the following line to yum.conf:
  exclude=libicu
Now you should be able to install Mono from the 1.0.6. FC3 yum repo.
Hope this is helpful.
Kind regards,
Danny Brugman

However, this repostitory seems to be broken, I receive the following
error message:
  Cannot open/read repomd.xml file for repository: mono115

This problem seems to have occured before, with the 1.1.4 release:
http://archive.neotonic.com/archive/mono-list/browse_frm/thread/7923/25909
The 1.0.6 repository is valid, but trying to yum-install mono from
that repository results in:
Error: Missing Dependency: libicuuc.so.26 is needed by package mono-core
Error: Missing Dependency: libicudata.so.26 is needed by package mono-core
Error: Missing Dependency: libicui18n.so.26 is needed by package mono-core
Installing 'libicu' from the Fedora Extras repository doesn't fix this.
I hope somebody can help me out and fix the repositories.
Many thanks.
