Re: [Mono-dev] Shutdown hangs
Switching to mono 4.0.5 seems a little better, but the problem (or a similar problem) is still there, and I get segfaults and other problems with 4.0. Does anyone have any suggestions for brute-force ways to fix this problem? E.g., can I modify ves_icall_System_Environment_Exit or similar to just call exit()? I haven't looked at the code but from the call stacks it seems like this happens in an attempt to make an orderly shutdown of threads. While that would be nice, it's much more important to me for the application to actually exit. If I have to, I'll make the process kill itself with SIGKILL, but I'd rather not since then I lose the actual exit code. chris -Original Message- From: mono-devel-list-boun...@lists.ximian.com [mailto:mono-devel-list-boun...@lists.ximian.com] On Behalf Of Chris Swiedler Sent: Monday, June 13, 2016 9:55 AM To: mono-devel-list <mono-devel-list@lists.ximian.com> Subject: [Mono-dev] Shutdown hangs I'm getting semi-reliable shutdown hangs in a mono command-line app using mono 4.2.3 on Centos 7 64-bit.

Re: [Mono-dev] High threadpool CPU usage
Well, looking at some pstack+top output, I’m not sure it’s GC anymore. I ran pstack and top as close to simultaneously as I could, and the high-cpu threads were just in pthread_cond_timedwait. Is it possible we get into a scenario where mono_cond_timedwait_ms is sleeping with a timeout_ms that's extremely short? Is there an easy way to force the compiler (#pragma or something?) to not optimize out the timeout_ms value? I'd rather not build all of mono with optimizations off, but I could disable optimizations for a few files. chris PID USER PR NIVIRTRESSHR S %CPU %MEM TIME+ COMMAND 17369 hydrogen 20 0 6491744 157928 17216 S 53.3 0.1 0:05.08 Threadpool work 17385 hydrogen 20 0 6491744 157928 17216 S 46.7 0.1 0:09.38 Threadpool work Thread 8 (Thread 0x7f52c65fc700 (LWP 17369)): #0 pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:238 #1 0x00618817 in mono_cond_timedwait_ms (cond=cond@entry=0x7f52c65fbdc0, mutex=0x2887808, timeout_ms=) at mono-mutex.c:181 #2 0x00586f28 in worker_park () at threadpool-ms.c:509 Thread 4 (Thread 0x7f528a7fe700 (LWP 17385)): #0 pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:238 #1 0x00618817 in mono_cond_timedwait_ms (cond=cond@entry=0x7f528a7fddc0, mutex=0x2887808, timeout_ms=) at mono-mutex.c:181 #2 0x00586f28 in worker_park () at threadpool-ms.c:509 From: Rodrigo Kumpera [mailto:kump...@gmail.com] Sent: Friday, May 27, 2016 5:07 PM To: Chris Swiedler <cswied...@trionworlds.com> Cc: Ludovic Henry <ludo...@xamarin.com>; mono-devel-list <mono-devel-list@lists.ximian.com> Subject: Re: [Mono-dev] High threadpool CPU usage Chris, Can you at least enable GC logging?

Re: [Mono-dev] High threadpool CPU usage
Thanks. I’ll try to use the profiler, but this problem doesn’t happen at startup, and running the application under profiling for eight hours is probably infeasible. I see that at one point mono support signal-based enabling/disabling of the profiler, like how SIGUSR2 toggles the trace mechanism on and off. Is that sort of functionality ever going to be re-added? Currently there’s the heapshot option via the TCP listener, perhaps there could be enable/disable commands via that mechanism? chris From: Ludovic Henry [mailto:ludo...@xamarin.com] Sent: Friday, May 27, 2016 1:27 AM To: Chris Swiedler <cswied...@trionworlds.com>; mono-devel-list <mono-devel-list@lists.ximian.com> Subject: Re: [Mono-dev] High threadpool CPU usage Hi Chris, The signal handler you are seeing is the GC signalling every thread to suspend them. So yes you are right, that's the sgen collector stopping the world. To track down the large number of allocation, I would encourage you to try the log profiler (documentation: http://www.mono-project.com/docs/debug+profile/profile/profiler/ ). That should give you some more insights in where the allocations are coming from.

Hi Chris,
I don't think we are keeping this counters up to date in the threadpool. Some
of them are kept up to date, but as we imported the threadpool implementation
from referencesources since 4.2, we must have missed this performance counter.
So you are certainly not doing something wrong.
If you want, you should fill a bug with the information you have so we have a
look at it as soon as possible.
Thank you very much,

Re: [Mono-dev] Cross Platform on Linux/Windows with Mono.Posix reference on Linux
Why not just include references to Mono.Posix.dll in the Windows build? You don't have to install the full framework. We have a similar issue with server apps that are developed on Windows and run on Linux. We just put a win32 build of Mono into our source tree and added Mono.Posix as a reference. Everywhere we invoke any Posix code, we just wrap the statements in something like "if (Environment.OSVersion.Platform == PlatformID.Unix)". chris -Original Message- From: mono-devel-list-boun...@lists.ximian.com [mailto:mono-devel-list-boun...@lists.ximian.com] On Behalf Of Edward Ned Harvey (mono) Sent: Tuesday, March 29, 2016 5:49 AM To: Greg Young <gregoryyou...@gmail.com>; Jason Curl <jcurln...@arcor.de> Cc: mono-devel-list@lists.ximian.com Subject: Re: [Mono-dev] Cross Platform on Linux/Windows with Mono.Posix reference on Linux > From: mono-devel-list-boun...@lists.ximian.com > [mailto:mono-devel-list- boun...@lists.ximian.com] On Behalf Of Greg > Young > > /> (for clarification of my previous response, because I was asked for clarification off-list) If you have some code that calls Mono.Posix.Something(), and you have a conditional reference to Mono.Posix in the project, then you're able to build on Mono, but on windows, without the reference, your call to Mono.Posix.Something() will not compile, which prevents you from building, even though at runtime you might never make that call. In order to compile on windows, you'll need to comment-out your Mono.Posix.Something() line, via #if or [Conditional], which means you need a compiler symbol to indicate whether you're building on mono or windows. This could be either separate project files, or multiple build configurations. (Or dynamically generated project files). Maybe you can have a conditional reference to Mono.Posix on mono, and have a separate conditional reference to ../../ExtraClassLibraries/Mono.Posix.dll on windows, with copy-to-destination, so you can get the same code to build on both mono and windows, resulting in an effectively identical cross-platform binary... But I'm almost certain I recall somebody on this list telling me, that the JIT compiler can or will or might in the future, eagerly link assemblies at runtime (or just before runtime), so the Mono.Posix.dll file must be present on windows at runtime in order to avoid runtime exceptions, even though the runtime code execution will never execute that path. You avoid all these problems by abstracting the functionality you want into an interface or abstract class, and using a factory to perform a runtime dynamic load of a mono-specific or windows-specific assembly with a derivative class. You can build the mono-specific assembly on mono, or maybe you can use the double-conditional described above and get the mono-specific assembly to also be buildable on windows. No need to copy Mono.Posix.dll to the destination, because Mono.Posix will only be called at runtime when run on mono. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

[Mono-dev] Debugging Mono applications under GDB
We have a server application that's being developed under Visual Studio and run under Mono 3.12. We're generating .mdb files from the .pdbs that VS creates. With those deployed next to the executable, mono will give full callstacks with source and line information when logging exceptions, so I believe the .mdbs are correct. I've read http://www.mono-project.com/docs/debug+profile/debug/ so many times I can quote it by heart, but I still can't get gdb to give me any useful symbols. I'm using gdb 7.6.1, so according to the docs, it should just use the JIT interface to get symbols. Is there any way to troubleshoot the loading of symbols by gdb? There are examples for how to generate xdb shared object files (I've tried them, but as doesn't like some of the assembly that MONO_XDEBUG generates) but nothing on the new JIT interface other than "it should work".

[Mono-list] Debugging Mono applications under GDB
We have a server application that's being developed under Visual Studio and run under Mono 3.12. We're generating .mdb files from the .pdbs that VS creates. With those deployed next to the executable, mono will give full callstacks with source and line information when logging exceptions, so I believe the .mdbs are correct. I've read http://www.mono-project.com/docs/debug+profile/debug/ so many times I can quote it by heart, but I still can't get gdb to give me any useful symbols. I'm using gdb 7.6.1, so according to the docs, it should just use the JIT interface to get symbols. Is there any way to troubleshoot the loading of symbols by gdb? There are examples for how to generate xdb shared object files (I've tried them, but as doesn't like some of the assembly that MONO_XDEBUG generates) but nothing on the new JIT interface other than "it should work". I do get errors like "../../gdb/dwarf2-frame.c:683: internal-error: Unknown CFI encountered." I'm not sure if those are relevant to my problem. A sample gdb session is below.

[Mono-list] Fwd: [PATCH] mono-4.xx.inc: disable parallel make
Hello.
I had posted last week about issues during the install phase of a
build due to the same file being installed multiple times.
From another user with the same issue it looks like the issue may be
related to parallel make.
Is this a known limitation when building mono?

To: chmor...@gmail.com
Cc: Richard Tollerton rich.toller...@ni.com,
ajlen...@dynamicdevices.co.uk, yo...@yoctoproject.org
A race was observed during `make install` of mono-native under
PARALLEL_MAKE=-j6:
/usr/bin/install: cannot change permissions of
build/tmp-glibc/work/x86_64-linux/mono-native/4.0.2.4-r0/image/
build/tmp-glibc/sysroots/x86_64-linux/usr/lib/mono/xbuild-frameworks/
.NETFramework/v4.5/RedistList/FrameworkList.xml: No such file or
directory
This is definitely a race, because FrameworkList.xml was present once
the failed build completed.
The present mono build doesn't appear to build much of anything in
parallel in the first place, and I would guess that this issue applies
equally to the mono and mono-native builds. So the correct place for the
workaround ought to be in the shared .inc file.

Re: [Mono-list] Does Properties.Settings.Default.Save() work under Linux
Thanks for replying. The first thing is, don't expect windows forms to be cross platform compatible. They're kinda sorta implemented in mono, but not good. The recommendation is to either design the business logic to be cross-platform, and then design the GUI separately for each platform (probably GTK# for linux), or use something that's intended to be cross-platform, such as Eto.Forms, or XWT. Yes, I understand that the implementation of windows forms is incomplete and not good, hence the question, Does Properties.Settings.Default.Save() work under Linux. Does the Save method work on mono? I am just trying to port an existing application to Linux and everything works fine except this.

Re: [Mono-dev] Update on Build System
It’s been about a year and thought I’d loop back on this thread since it’s still something I could really use. Are we yet to a point where we can build Mono using the Microsoft compilers only?

There are still a number of problems that I need to address: * Installing the resulting binaries * Signing (currently we are skipping this) * Ensure the binaries produced are identical with Make and msbuild * Add assertions to ensure that flags that we currently ignore are caught, in case we add new features in the future * Fix the C# compiler build (currently disabled) * Extend this to other components, so we can have the entire setup in a solution.

Are there any plans to update the build system to allow us to compile the runtime itself using Visual Studio (i.e. a Microsoft compiler)? Now before everyone starts with the eye rolling and “why the hell would you want to do that?” questions, let me explain. As of today, we can create applications in C# that will run on Windows and a large array of Linux machines (including Android) but Windows CE has been orphaned. Microsoft is not putting any effort into the Compact Framework, but there are still people developing for Windows CE devices. I’d like to put a last nail in the coffin of the Compact Framework by getting Mono supported on Windows CE so we can all move into using technology from the current decade, not the last one. I don’t see any real path for getting the runtimes to compile for Windows CE for ARM and 586 (not 686, since we have new Intel processors now that are 586 based). There is an old (last touch in 2009) CeGCC project that might be a step, but I was hoping for something a little simpler.

Those working on libraries that had cross dependencies will enjoy reliable and working builds. If you make a change in say System, and you type make in mcs/class/System, it will make sure that all the dependencies are properly compiled and the result will be stable. #2 MSBuild setup Based on the work above, I have updated the MSBuild setup, and it is now possible to build most of the managed code with xbuild. This means that you can use this from Visual Studio or Xamarin Studio. Since xbuild does not support passing /keyfile to the C# compiler, I still have to fix about 6-7 assemblies that use -keyfile to be signed. Once that happens, you should be able to build all of Mono's managed code with: xbuild msvc/scripts/net_4_5.sln Currently I disabled generating project files for profiles other than 4.5, just because it is easier to debug this way. I am also a bit sad that our xbuild does not have any support for parallel builds, it would have been a neat hack to make the xbuild-based build system parallel and get this for free. #3 Future Parallel Work - Makefiles I tried to implement parallel builds for mcs/class/Facades, and while it works, it regressed some of the other standard targets that we have (the other -local). I will have to revisit this later. But the principle behind the patch that enabled this could be used for mcs/class and parallelize all the builds as well. We only need to (a) generate the assembly dependencies [1] and (b) we need to figure out the -local target breakage (same stuff I broke for Facades).

[Mono-dev] Text Input Source Services
Hello,
I would like to access Text Input Source Services from a mono app. I would
like to get the id, localized name, and primary language of all the currently
configured keyboard input sources. I also want to change the selected keyboard
input source during my application depending on which field is being typed in
(it is an app that manages lexicon information and we want to change the
keyboard depending on the writing system of the field being typed in).
Text Input Source Services lives in the Carbon.framework but is not a Carbon
API.
Here is the Objective-C code that I would like to write in C#:
const void *keys[] = { kTISPropertyInputSourceCategory };
const void *values[] = { kTISCategoryKeyboardInputSource };
CFDictionaryRef filter = CFDictionaryCreate(kCFAllocatorDefault, keys,
values, 1, NULL, NULL);
NSArray *sources = CFBridgingRelease(TISCreateInputSourceList(filter,
FALSE));
for (NSUInteger i = 0; i sources.count; ++i) {
TISInputSourceRef source = (__bridge TISInputSourceRef)sources[i];
NSString *Id = (__bridge NSString *)TISGetInputSourceProperty(source,
kTISPropertyInputSourceID);
NSString *LocalizedName = (__bridge NSString
*)TISGetInputSourceProperty(source, kTISPropertyLocalizedName);
NSArray *Languages =
CFBridgingRelease(TISGetInputSourceProperty(source,
kTISPropertyInputSourceLanguages));
NSString *primaryLanguage = NULL;
if ([Languages count] 0) {
primaryLanguage = [Languages objectAtIndex:0];
}
// Do something with these properties in C# code
NSLog(@Id=%@, LocalizeName=%@, Primary Language=%@, Id,
LocalizedName, primaryLanguage);
}
CFRelease(filter);
The challenge I saw with this is exposing constants (from TextInputSources.h).
For example:
extern const CFStringRef kTISPropertyInputSourceCategory;
Are there any examples of this? I don’t know how the API implementation is
doing comparisons (pointer value or string comparisons--and it could change
over time).
Another options is to use the Cocoa API NSTextInputContext (from
monomac/src/appkit.cs):
[Static]
[Export (localizedNameForInputSource:)]
string LocalizedNameForInputSource (string
inputSourceIdentifier);
[Export (keyboardInputSources)]
NSArray /* NSString [] */ KeyboardInputSources { get; }
[Export (selectedKeyboardInputSource)]
string SelectedKeyboardInputSource { get; set; }
The first one (LocalizedNameForInputSource) already exists. I added the last
two in a local build and they worked correctly. They only thing missing from
the Cocoa API is getting the primary language of a keyboard input source based
on the input source identifier.
So my questions are:
1) What is the proper way to expose Text Input Source Services to Mono code?
2) OR Is there a Cocoa way to get the language of a Keyboard Input Source?
3) OR should a create a Objective-C Library that wraps Text Input Source
Services and make a interop for that library?
Thanks,
Chris Hubbard

I’ve been working on this for a while and I’ve come to the conclusion that I probably won’t finish it without help: https://www.dropbox.com/s/1qc0dozzqmhsemw/SpeechSynthesizer.zip?dl=0 https://www.dropbox.com/s/1qc0dozzqmhsemw/SpeechSynthesizer.zip?dl=0 The original motivation for this work was to get the Telerik Captcha control working on the Mac platform. I knew Mac OS X had a built-in speech synthesizer that could be utilized to provide this functionality. In order to access this functionality, I built wrapper classes for the necessary AudioToolbox, CoreFoundation, and SpeechSynthesis API calls. Along the way, I noticed that the SoundPlayer class did not work on OS X. I’ve implemented the basic functionality to play a file and play a stream but I haven’t implemented all features supported by the SoundPlayer class. I’ve tried to match existing .NET class functionality and behaviour whenever possible. I’ve also tried to unit test where appropriate but more could be written. I believe the code should be compatible with OS X 10.8 on-ward, but that’s a guess. This would be my first contribution to the mono project. How would work like this be integrated typically?

We aren't storage constrained, so 100MB+ for us was ok. System with an arm cortex a8 processor, the beaglebone black actually. Found out that for every instance of mono we had running that there was some 17MB of ram overhead. In addition, there is a little bit of a startup time delay, a second or so, before the the runtime is running our code. I had asked here about the ram overhead but there wasn't any response about how to shrink it down or what might be contributing to it a bit. We would have been ok with maybe 5MB per process. Keep in mind that I was testing with a pretty trivial application, it wasn't doing lots of memory allocations, so nothing in the application could explain why 50k of memory allocations translated to 17MB of overhead. We ended up rewriting four or five smallish utility applications from c# into c++ and leaving a single application of high complexity as our sole c# application that will run on the system. This dropped off 17MB * 4 of ram and reduced startup time for these applications to fractions of a second.

Re: [Mono-dev] What's the most efficient way to do XOR two byte arrays?
There is virtually no difference between Array.Copy and Buffer.BlockCopy when dealing with large buffers. If you are rapidly calling Array.Copy with smaller buffers, then yes, you can save some milliseconds if you switch to Buffer.BlockCopy, because it skips checks / makes less function calls, and there's less overhead. As I said, the difference comes to play when we are dealing with very small data rapidly. That said, you can make some serious gains when you're dealing with large buffers. You just need to parallelize it, and make sure there is no false cache sharing. The other trick is to see what Mono.Simd offers. I don't see a reason why Xoring 128-bit blocks at once shouldn't be possible. You want something similiar: http://stackoverflow.com/questions/15067119/how-can-i-use-simd-to-accelerate-xor-two-blocks-of-memory Note I have absolutely no experience with Mono.Simd but I imagine it's pretty cool. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

[Mono-dev] Building mono on Windows issues.
Hello all, I have question regarding building mono on windows, namely I've tried a lot of times, and had a lot of different problems(such as missing some dependencies, git converting *.sh files to CRLF ending and cygwin not being able to interpret them, etc..) however I've reached now to a point where I can run `make` for a little while, and then receive the error: In file included from socket-io.c:30:0: /usr/i686-pc-mingw32/sys-root/mingw/include/ws2tcpip.h:38:2: error: #error ws2tcpip.h is not compatible with winsock.h.

I ran a grep to look for winsock.h from mono dir, but there's nothing about that. That file seems to be crawling in from some arbitrary place?! After that, I tried to compile with DISABLE_SOCKETS, and then I arrived to this place: ./.libs/libmini.a(libmini_la-debugger-agent.o): In function `socket_transport_connect': /cygdrive/c/GITHUB/mono/mono/mini/debugger-agent.c:1236: undefined reference to `mono_network_init' At this point, I have no idea what to do.

[Mono-aspnet-list] Mono ASP.NET vs MS VS
Hi, I am trying to build an ASP.NET website in C# using Razor templates in MS Visual Studio that will then run in Mono on Linux. I have never attempted to run an ASP.NET site with Mono before now, and I only played with MonoDevelop briefly when I last explored Mono a couple years ago. I have mono-complete and mono-fastcgi-server4 installed from Xamarin's deb on my Xubuntu 14.04 desktop VM (running in VirtualBox): sudo add-apt-repository 'deb http://download.mono-project.com/repo/debian wheezy main' # etc When I use Xamarin Studio 5.4 in Windows 7 (downloaded 5.0.1.3 from monodevelop.com and then upgraded in-app) to create a new solution of type C# ASP.NET ASP.NET MVC Razor Project, and then copy the bin dir, Views dir and Global.asax + Web.config + package.config files into my Linux machine's /var/www/ directory, and finally run xsp4 there, everything works fine. Fine here meaning that I open localhost:9000 and see a simple page that says: Welcome to ASP.NET MVC 5.2 on Mono! (Note that I can also accomplish this with nginx + mono-fastcgi-server4.) When I then use Visual Studio 2013 Professional Update 3 in Windows 7 to create a new solution of type Visual C# Web ASP.NET Web Application Empty check MVC, and then copy from the Xamarin solution I just created (for demo purposes): Controllers/HomeController and all the contents of the Views dir except Web.config (note that MS VS uses web and Mono/Xamarin uses Web, if ever that might matter). I then right click on the project in MS VS and then Publish Custom (name it) Publish method: File System Target location: (somewhere). Once that is published locally, I will then copy that dir into my /var/www in Linux and finally run xsp4 there, where I see this error displayed in the browser when I open localhost:9000 : System.InvalidCastException Cannot cast from source type to destination type. Description: HTTP 500.Error processing request. Details: Non-web exception. Exception origin (name of application or object): System.Web.WebPages.Razor.

Confirm that the path in the Import declaration is correct, and that the file exists on disk. C:\Users\Chris\Documents\Visual Studio 2013\Projects\MonoSite\MonoSite\MonoSite.csproj Now, I am an experienced C# developer and used to do C and C++ once upon a time, so I would like to contribute / help myself here: 1) If there is something easy and obvious that I am missing in my config, please let me know. (e.g. the global or Views web.config files are different between MS VS and Mono, for sure, but I am not an expert with these files to know exactly what is needs to be changed in the MS VS one, if anything, to fix this situation) 2) Otherwise, any advice on how I could figure out exactly where this error is coming from? What dll is missing or what line in my config xml is not right, etc? How can I debug an ASP.NET application in Mono -- using xsp4 or monodevelop anything else? 3) What do I need to do to get an ASP.NET solution created in MonoDevelop to open in MS VS? (Hopefully this is the same solution as getting my MS VS ASP.NET site to work in Mono/xsp4.) 4) Any advice on where Mono might already have a Publish feature like MS VS has in MonoDevelop? Or else where I should go add one if no such feature yet exists, if it acceptable to the team in charge of this product (I don't want to do it, submit a pull request and be told it is an undesired feature). Such a feature would very helpful for me. Thanks! --- Chris Rogus ___ Mono-aspnet-list mailing list Mono-aspnet-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-aspnet-list

Yes you need things to be updated and made to work so you get people wanting to use the platform.

I'm as frustrated with the current process as most as I've been waiting for the MVC5 stuff to be fixed and merged for a while. What I would say is though, I'd prefer for MVC4 to continue working as is, than some MVC5 stuff work and MVC4 become unstable. You have to appreciate the position Miguel and the mono team are in. They have a commercial product to maintain, that without that, they wouldn't be able to eat (or put on what I've been told are awesome parties). At the end of the day, having mono is better than not. Also, it's better maintained than some other open source projects. That said, I think that there isn't enough time, currently, dedicated to code that isn't useful to Xamarin. They have taken stewardship of a platform that goes beyond mobile platforms, and are controlling the elements that are not part of their core business, however, they are acting as a bottleneck for those. In short, there is a lot room for improvement, but where we are is by no means a bad position. Just my two (or possibly four) cents.

If using Debian I believe they also have packages for arm. I looked at running mono applications on the bbb but quickly ran into an issue where each instance of mono is using ~14MB of ram. With only 512MB of ram available this overhead was high enough that we've switched away from mono and back to c++11. I'd be interested in what you see for memory overhead when running on the embedded side. My testing so far when looking at memory is on the desktop side so I'm not sure if the memory overhead will be present on the embedded side.

[Mono-dev] Debugging on a remote (non-Android) Linux Device
I have a Mono project that mirrors a desktop project (same code, same projects, etc). Most development and debugging is done in Visual Studio and the Linux/Mono deployment is done on the build server with a command-line call to compile the Mono build. Generally speaking this all works just fine. Occasionally, however, we find behavioral differences between the .NET Framework and Mono. For example, right now I have code that works fine on the desktop, but under Mono it's failing (it's a socket call out to SSL, and yes, I've added a handler for ServicePointManager.ServerCertificateValidationCallback as a test but it still fails). When I run into these types of problems, I use Xamarin Studio to add in Console.Writeline calls, build, copy via USB, reiterate cycles and try narrowing the problem down. It's extremely slow and painful. Xamarin Studio can connect and live debug against iOS and Android. Is there a way to configure Xamarin Studio (or Visual Studio) and my Linux device to do the same? I would suspect that someone out there has tried debugging against a Raspberry Pi or something and this would be an analogous situation. If it matters, the Mono build I'm using is not off-the-shelf - I had to compile it myself since we're targeting the i586-cored Quark processors. I used to have a license for both Xamarin iOS and Xamarin Android, but really we don't target those devices so I let them lapse. I'm hoping that the debugging pieces aren't wrapped up in those. -Chris ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

“Let a real web server be the web server” isn’t much of an answer. It’s likely that the solution doesn’t allow the use of a “real” web server or he likely wouldn’t be asking the question. I have a similar scenario where I’m going to need to serve up over SSL and I can’t use one so I, too, am interested in how this will work out. I’ve probably got a little time until I have to fully commit to a solution, but it sounds like several of us are trying to solve the same problem. -Chris From: Edward Ned Harvey (mono)mailto:edward.harvey.m...@clevertrove.com Sent: Friday, August 8, 2014 9:28 AM To: DrGusmanmailto:geni...@gmail.com, mono-list@lists.ximian.commailto:mono-list@lists.ximian.com From: mono-list-boun...@lists.ximian.com [mailto:mono-list- boun...@lists.ximian.com] On Behalf Of DrGusman I will add the patches you said on the previous postto my mono branch and will give it a try, if found it's really unstable or troublesome then I will use one of my backup plans, add a nginx router which will do the ssl decryption or using also nginx connect through FastCGI. Oh yeah. I would expect, if you want to run C# on a web server, it's almost certainly best for you to do some of the ASP stuff, fastcgi, or similar. In other words, let a real web server be the web server, because they're focused on making web servers stable, secure, and supportable. I hope with the Xamarin boom the mono project get more alive as novell left it semi abandoned when was sold, the las 3.7 mono version is really a giant leap and Miguel and it's team seem to be working really hard (I am also a Xamarin customer, got MT and MD). Maybe. But I'm doubtful. It seems to me that Xamarin is focused only on mobile devices and basically nothing else. (Even coverage for mono on OSX is very sparse.) I'm curious, what do you plan to do to stop using the SslSocket? We need to make at least a small research project into that. I'm guessing it will probably be Bouncy Castle. Not 100% sure yet. Perhaps openssl - but since they're really C++ with a crude managed wrapper around it, we might not use openssl for that reason. Bouncy Castle is at least *meant* to be managed code, but I recently uncovered a kind of major flaw with their SecureRandom, which apparently gets used all over the place, so we'll see.

[Mono-dev] Mono, TDS and SQL Server 2012
I'm trying to add SQL Server support to the Mono (on Linux, not Android if it
matters) version of one of our products.
I have a codebase that works fine on Windows, but under Mono, it's not
behaving. We're using SQL Authentication, not NT.
I am able to get back a list of table names, so I know it's talking to the
database, but when I attempt to query rows from a table I get this:
[ERROR] FATAL UNHANDLED EXCEPTION: System.Exception: Unknown packet type 129

So it looks like the TDS version in Mono is old, maybe? Packet type 129 looks
like it's a result packet:
http://www.freetds.org/tds.html#t129
And it's been in use since SQL Server 7, which itself is pretty far from
recent.
So my questions, I guess, Are:
- Is connecting to a SQL Server 2012 database from a Mono app a
supported scenario?
- Is there a newer version of TDS on the System.Data.* stuff available
that adds support?
- Has anyone had any luck connecting to a modern version of SQL
Server?
- Any thoughts on how to proceed (other than debugging and attempting
to implement this stuff myself)?

Re: [Mono-dev] Mono, TDS and SQL Server 2012
Martin,
Thanks. Here are the details:
- Running on Wind River Linux 3.4.43.5 on a Quark processor
- Mono 3.2.7, built from source by me, specifically for 586 processors
- CLR Version 4.0.30319.1720
Repro is actually pretty simple. Create a SqlCommand and the call this:
command.ExecuteScalar(“SELECT SERVERPROPERTY('productversion')”);
And it goes south. It also fails if you use ExecuteReader with the same
statement and try to read the first field of the first row.

Couple of things that will help.
Mono version, platform and whether it was compiled from source or installed by
soke other means
Sample app (not your entire codename, just a basic console app that replicates
the issue).
In the first instance I would look at replicating this using basic stuff, I.e.
Just a basic datareader on the table in a bear console app.
I believe it does work against 2012 though. So I could be a specific data type
or possibly specific data that's causing it.
I can possibly try to replicate on Sunday if you don't get any further
response, but I think it's highly likely it's data or configuration specific
not sql version.

Re: [Mono-dev] Debian CI PPA for Ubuntu/Debian
Agreed. My major pain point with the distro right now is in CI. I'm using Jenkins on a Windows machine to build our C# application products and installers for both Windows and Linux platforms. I have it all working, including generating tarballs for Linux. The one problem is that I don't have it pulling and rebuilding Mono, because my steps for that are done on a separate Ubuntu VM. That makes it a manual (i.e. not done very often because I'm too busy) process. It also seems inefficient because anyone else looking for a scaled down (we customize what goes into the build to exclude winforms and a lot of crusft that simply isn't needed for a headless embedded device), 586 device like the Intel Galileo dev system is unlikely to ever find our Mono tarball on our public FTP. A central CI system and a central repository for builds would be very useful in reducing fragmentation. -Chris From: bobsummerw...@gmail.com [mailto:bobsummerw...@gmail.com] On Behalf Of Bob Summerwill Sent: Monday, June 16, 2014 10:03 AM To: Miguel de Icaza Cc: Chris Tacke; mono-devel Subject: Re: [Mono-dev] Debian CI PPA for Ubuntu/Debian Hey Chris and Miguel, I need to support an extra platform too, for Tizen (see http://monotizen.com).

It is great that Xamarin is bringing Linux support back up to first-class support, but there will always be a role for community supported lesser platforms, and there is no need or benefit in trying to do those in the same way as the core platforms.

Re: [Mono-dev] Update on Build System
Miguel, This is great news. Are there any plans to update the build system to allow us to compile the runtime itself using Visual Studio (i.e. a Microsoft compiler)? Now before everyone starts with the eye rolling and “why the hell would you want to do that?” questions, let me explain. As of today, we can create applications in C# that will run on Windows and a large array of Linux machines (including Android) but Windows CE has been orphaned. Microsoft is not putting any effort into the Compact Framework, but there are still people developing for Windows CE devices. I’d like to put a last nail in the coffin of the Compact Framework by getting Mono supported on Windows CE so we can all move into using technology from the current decade, not the last one. I don’t see any real path for getting the runtimes to compile for Windows CE for ARM and 586 (not 686, since we have new Intel processors now that are 586 based). There is an old (last touch in 2009) CeGCC project that might be a step, but I was hoping for something a little simpler. I’m up for any suggestions. -Chris Tacke From: mono-devel-list-boun...@lists.ximian.com [mailto:mono-devel-list-boun...@lists.ximian.com] On Behalf Of Miguel de Icaza Sent: Friday, May 23, 2014 9:59 PM To: mono-devel Subject: [Mono-dev] Update on Build System Hey guys, #1 Makefile Build System Update So the clean staged setup has been added to mono/master and in practice most of you will never notice an improvement. Those working on libraries that had cross dependencies will enjoy reliable and working builds. If you make a change in say System, and you type make in mcs/class/System, it will make sure that all the dependencies are properly compiled and the result will be stable. #2 MSBuild setup Based on the work above, I have updated the MSBuild setup, and it is now possible to build most of the managed code with xbuild. This means that you can use this from Visual Studio or Xamarin Studio. Since xbuild does not support passing /keyfile to the C# compiler, I still have to fix about 6-7 assemblies that use -keyfile to be signed. Once that happens, you should be able to build all of Mono's managed code with: xbuild msvc/scripts/net_4_5.sln Currently I disabled generating project files for profiles other than 4.5, just because it is easier to debug this way. I am also a bit sad that our xbuild does not have any support for parallel builds, it would have been a neat hack to make the xbuild-based build system parallel and get this for free. #3 Future Parallel Work - Makefiles I tried to implement parallel builds for mcs/class/Facades, and while it works, it regressed some of the other standard targets that we have (the other -local). I will have to revisit this later. But the principle behind the patch that enabled this could be used for mcs/class and parallelize all the builds as well. We only need to (a) generate the assembly dependencies [1] and (b) we need to figure out the -local target breakage (same stuff I broke for Facades).

[Mono-dev] Running autogen.sh from outside of source tree?
Hello. I'm trying to build mono under Yocto. Recently (so I've heard) there were some changes such that the autotools scripts are being run from outside of the source tree. I presume this is something like: cd mono mkdir monobuild cd monobuild ../autogen.sh [cmorgan@localhost monobuild]$ ../autogen.sh --prefix=/home/cmorgan/mono-prefix grep: configure.in: No such file or directory ../autogen.sh: line 125: mono/mini/Makefile.am: No such file or directory ../autogen.sh: line 126: mono/metadata/Makefile.am: No such file or directory Running aclocal -I m4 -I . ... aclocal: error: 'configure.ac' is required **Error**: aclocal failed. This may mean that you have not installed all of the packages you need, or you may need to set ACLOCAL_FLAGS to include -I $prefix/share/aclocal for the prefix where you installed the packages whose macros were not found This doesn't appear to work because several things in autogen.sh assume that the files are present in the current working directory. Some other steps however do use $srcdir. My question is whether it seems like a reasonable idea to correct autogen.sh to remove the assumption that builddir == sourcedir. If so then I'll go down this route and send a patch. If not then I'll use a Yocto work around for projects that don't/can't support doing that. I'm not big on papering over issues so I do prefer the first option but I didn't want to start work if it turns out that it may be a nearly impossible task.

Its to avoid having to use autotools-broken vs. autotools scripts when building mono in Yocto.

Re: [Mono-dev] Running autogen.sh from outside of source tree?
Hmm. I don't see any mention of NOCONFIGURE=1 in README.md. If it were possible to run autogen.sh from outside of tree it would make building under Yocto a little bit cleaner. Yocto is very particular about separating source from build from installed files so they can automate package generation, check for misbehaving packages etc. What is interesting is that a good portion of autogen.sh is ok with being run out of the source directory. Is it feasible to continue to improve autogen.sh to be run from outside of the source directory? If so, I can hack on it a bit tomorrow and see how I make out.

A key component of what I was told toay is that Xamarin are unable to work on Mono due to contractual obligations to Attachmate. As a result they are (I am told) abandoning Mono and doing something else which is the (presumably) VM underneath the Xamarin tooling. I guess I'm looking for confirmation that either this is true, or is some strange new form of FUD :) This comes from a discussion which was originally about Microsoft open sourcing (ish, bits of) .Net. I care, because I think Mono is pretty fantastic, it allows me to retarget products my business creates to embedded devices running Linux, and I want to see it continue and grow. If the death of Mono were to be a reality I would need to rethink some objectives. Which is why I asked you guys, because I figure if anybody can give me a categorical answer then it is the developers...

It also says as follows: ...the future of the project was questioned, since MonoTouch and Mono for Android would now be in direct competition with the existing commercial offerings owned by Attachmate. It was not known at the time how Xamarin would prove they had not illegally used technologies previously developed when they were employed by Novell for the same work. In the Mono project website (www.mono-project.comhttp://www.mono-project.com), you have three main offerings, Mono, Xamarin.iOS and Xamarin.Android, and you can find a link (at the bottom left corner of the page) to Xamarin's website. It is clear that this is a strategy by Xamarin to offer MonoTouch developers a migration path to Xamarin tools, and not much more than that. To be able to woo Mono developers to Xamarin, Novell (Attachmate) and Xamarin cut this deal, because it is of mutual convenience to the two of them. But from any real perspective of active development of the platform, Mono is dead. ...

Since the csproj files have dependencies presumably you create (ad-hoc?) solutions (which you don’t check-in?) whilst working on them?

[Mono-dev] Installing mono via copy
I have an embedded Linux platform on which I need to install Mono. The platform does not have any installer tools like apt or whatever. I have to custom build Mono for the platform for a variety of reasons. I am successfully building Mono from source under an Ubuntu machine. That works just fine. The problem I'm now facing is how to distribute the resulting build. Due to size contraints, I've compiled only the 4.5 stuff, plus I've pulled out a variety of things like System.Drawing, all of the WinForms stuff, etc. I've also stripped the binaries. What I did was: - set a custom prefix (and other stuff) during configure - make make install. - Go into the install folder and trim out stuff I don't need and strip binaries So now I have a set of folders that contain Mono. My hope was that I could tar these up, copy that to the destination, untar it in the /usr directory so that the mono bin files end up in /usr/bin, the mono lib files end up in /usr/lib etc. Doing this I success if I do a mono -V. I get version info. However, if I try to actually run a mono app, it complains about not finding mscorlib.dll. It's looking in the path where I set the prefix back on the build machine. How should I be going about doing an installation like this?

Yes, that's what I'm trying, but the target environment isn't getting set up properly. I tar it all up, install on the target device and I get errors when I try to run. The first error I'm seeing is that it can't find mscorelib.dll, but I suspect it's only the first of many because mono on the destination device isn't in the same location as it was on the build machine. -Chris -Original Message- From: Brandon Perry [mailto:bperry.volat...@gmail.com] Sent: Friday, December 13, 2013 10:19 AM To: Chris Tacke Cc: mono-devel-list@lists.ximian.com Subject: Re: [Mono-dev] Installing mono via copy Tarball?

[Mono-list] MonoObject reference changing to other object type
I'm embedding mono and it's in a threaded environment so was hoping that a simple explanation of what I'm doing might shed some light on where I am going wrong, before I post the code. I'm embedding in java 7 via the jruby ffi. I have a C function that calls mono_object_new and returns it as a pointer to jruby. Some time later I call another C function with the MonoObject, and when I call mono_class_get_name on the object's klass, I get back random classes. My function that creates the MonoObject is hard wired to a specific namespace/class. I'd say roughly 20% of the time I get back a random class, it's not always the same. The threading involved comes from Akka. I am creating the mono object in one thread and usually using it in another, but never is a mono object used concurrently by different threads. I'm also using mono_thread_attach liberally at this point. Anything obvious that sticks out? Seems like a threading issue of some type. If I'm missing a call to mono_thread_attach somewhere, would this behavior be expected? Chris ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

Re: [Mono-list] embeded mono segfaults without calling managed code
Hey thanks that solved most of the problem. I'm getting a segfault now when I call mono_thread_attach(mono_domain_get()) at some point later in a thread that's not the main thread. I have a functions to load the image, create objects, and call methods on those objects. What works is if I create the image and objects in the main thread, then make calls to the objects from any other java thread. What's strange is that when calling a method on the object in another thread, if I pass mono_domain_get() to mono_thread_attach it segfaults, but if I get the domain by calling mono_object_get_domain on the object I am calling a method on, it works fine. I'll post more info when I get it. This kind of stuff might be good to put in the embedding docs.

[Mono-dev] Use of mono-sgen causes mono path detection fallback
I maintain a Linux build of mono (and F#) that is hosted via NFS, and used on a large number of machines, but the mount directory is not always identical. I have discovered that the mono-sgen binary does not properly detect the location of mscorlib on my systems, but the normal mono binary has no problems. This problem occurs in both 2.10.9 and 3.0.4. My simple test case (for mono 3.0) is to build the runtime, rename the output directory, and run the following: MONO_GAC_PREFIX=/tmp/mono-test/renamed \ PATH=$PATH:/tmp/mono-test/renamed/bin \ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/tmp/mono-test/renamed/lib \ /tmp/mono-test/renamed/bin/mono /tmp/mono-test/renamed/lib/mono/4.5/sn.exe MONO_GAC_PREFIX=/tmp/mono-test/renamed \ PATH=$PATH:/tmp/mono-test/renamed/bin \ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/tmp/mono-test/renamed/lib \ /tmp/mono-test/renamed/bin/mono-sgen /tmp/mono-test/renamed/lib/mono/4.5/sn.exe The first command succeeds (prints out the usage). The second command fails, returning: The assembly mscorlib.dll was not found or could not be loaded. It should have been installed in the `/source/on/build/server/lib/mono/4.5/mscorlib.dll' directory. I have traced the issue to mono/metadata/assembly.c:compute_base: /* Not a well known Mono executable, we are embedded, cant guess the base */ if (strcmp (p, /mono) strcmp (p, /monodis) strcmp (p, /mint) strcmp (p, /monodiet)) return NULL; By changing this as follows, the behavior is corrected: /* Not a well known Mono executable, we are embedded, cant guess the base */ if (strcmp (p, /mono) strcmp (p, /mono-sgen) strcmp (p, /monodis) strcmp (p, /mint) strcmp (p, /monodiet)) return NULL; I have not filed this as a bug or submitted a patch yet, because I am not sure if other binaries should be included in this test as well (e.g. pedump).

[Mono-list] ConfigurationErrorsException loading user settings (duplicate key)
A few years ago zidjian pointed out an issue on OSX where he was not able to read 'application' scoped settings from his app.config file. Attempting to do so resulted in a ConfigurationErrorsException which explained that there was a duplicate key for that 'application' scoped setting. I'm seeing this same issue on Ubuntu and would like to ask the general forum if there is a known solution for this. When zidjian asked he posted it in the OSX forum so there may have been limited visibility. In the end he solved the problem by changing the the scope from 'application' to 'user'.

Re: [Mono-list] ConfigurationErrorsException loading user settings (duplicate key)
I've resolved the issue. The source of my problem is that some of my settings had previously been 'user' scoped. For this reason the config file located in ~/.local/share/ set them to a default value. Like all settings they were also defined in the config file that sits alongside my executable. 'application' scoped settings should not be defined in multiple locations so an error was thrown when a duplicate key was found. In the end I was able to resolve the issue by deleting the config file in ~/.local/share/ and allowing it to be replaced by a file that does not mention the 'application' scoped settings. -- View this message in context: http://mono.1490590.n4.nabble.com/ConfigurationErrorsException-loading-user-settings-duplicate-key-tp4658540p4658541.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

Hi, I decided to take contributing to Mono seriously about 6 months ago. I've been working on an implementation of the System.Speech namespace in my spare time (which isn't much). The implementation right now is targeted at using the underlying Mac Speech API but I'm hoping it will expand to other platforms later. I typically do web development and use the Telerik controls extensively. I'd like to get the .NET 3.5 version of their controls officially supported, so I ran MoMa on their web DLL and pick this api to start with. The use of the System.Speech api in their case seems to be limited to speaking Captcha text.

Can you create your own links to the correct files? That might require a config script, but that is probably the correct way to handle the problem. It would be a huge pain. Users now just download the library, add it as a reference in their project and go. Adding a config script that would require root access to modify their filesystem would be a pain.

id=?oldId, conn);
da.DeleteCommand = new MySqlCommand(DELETE FROM mytable WHERE id=?id,
conn);
da.InsertCommand.Parameters.Add(?id, MySqlDbType.VarChar, 5, id);
da.InsertCommand.Parameters.Add(?name, MySqlDbType.VarChar, 40,
name);
da.UpdateCommand.Parameters.Add(?id, MySqlDbType.VarChar, 5, id);
da.UpdateCommand.Parameters.Add(?name, MySqlDbType.VarChar, 40,

da.UpdateCommand.Parameters.Add(?oldId, MySqlDbType.VarChar, 5,
id).SourceVersion = DataRowVersion.Original;
da.DeleteCommand.Parameters.Add(?id, MySqlDbType.VarChar, 5,
id).SourceVersion = DataRowVersion.Original;
return da;
}
When I run this code I get an error message saying that Column 'id' cannot
be null. Just like NpgSQL the update method is unable to populate the
Parameters properly. I have created a work around that seems to work, but
it makes me nervous so I would like see if I can't get the update method to
function properly. Here is the work around:
foreach (System.Data.DataTable dataTable in ds.Tables)
{
foreach (System.Data.DataRow row in dataTable.Rows)
{
//Update if the row was changed
if(row.RowState.Equals(System.Data.DataRowState.Modified))
{
foreach(NpgsqlParameter param in
da.UpdateCommand.Parameters)
{
param.Value = row[param.SourceColumn];
}
if(!da.UpdateCommand.Connection.State.Equals(System.Data.ConnectionState.Open))
{
da.UpdateCommand.Connection.Open();
}
da.UpdateCommand.ExecuteNonQuery();
}
//Then I repeat this for the Insert and the Delete Commands
}
}
As you can see the work around is kinda ugly and makes me nervous. Any help
getting DataAdapter.Update to work would be greatly appreciated!
Thanks,
Chris
