Re: [Mono-dev] mono embed: passing arrays from and to unmanaged code
thank you, that was really useful!
now my problem is that i'd need to pass an array of struct.
a very simple struct like this one
- in C
typedef struct atom_simple
{
int a_type;
float float_value;
MonoString *string_value;
};
- in C#
[StructLayout (LayoutKind.Sequential)]
public struct Atom
{
public int type;
public float float_value;
public string string_value;
}
I'd like to put those struct in an array but i need a MonoClass to create
the MonoArray, something like:
MonoClass *c = mono_class_from_name (image, PureData, Atom);
mono_array_new (domain, c, argc);
but is this the right thing to do? i mean does mono_class_from_name () work
on struct also?
if not, is there another way i can create a monoarray ?
sadly the examples in samples/embed don't cover this.
thank you,
Davide.

See mono/docs/internal-calls.
An array argument passed to an icall will look like a MonoArray*
argument on the C side.
A MonoArray* is a reference so it is passed to managed functions like
any other reference. See mono/samples/embed/*.c for many invocation
examples.

Yes. After you've allocated the array, you can fill it up using
the mono_array_* macros declared in metadata/object.h.

[Mono-dev] AJAX problem with Mono
Hello all, I am having some problems installing AJAX in conjunction with Mono. Everything seems to have went well up until I tried to call a serverside _javascript_ function. I got an error saying object undefined. I then tried to navigate the SRC of the apparently created _javascript_ include, and there was nothing. I got an error saying file not found. I think I configured my http handlers correctly, at first I was placing the app in the subdirectory of another Mono app, and so changed it to its own space on my server. Still generated problems. Ajax is either creating the files and placing them where I cant see them, or its not creating them at all. I followed the instructions that came with AJAX implicitly and I am still having problems. Can AJAX even be installed on MONO? Does anyone have any success stories? I know I am calling the registerAjax function properly, because I get the output in my source. I just cant see where the outputted JS files are being place. Another thing too, is AJAX supposed to place the JS include code right before a FORM object or in the head? It outputs the JS include right after a form element, could this be a problem? Any help would be greatly appreciated.

RE: [Mono-list] Profiling web app to find where memory is going
I'm not sure if this is related but there are some terrible inefficiencies in
following two classes

mcs/class/System.Web/System.Web/HttpWriter.cs
I've not had a chance to make a patch yet, so I'll explain so someone else can
if they want to get it done before I can. But suffice to say that how one calls
Write on a TextWriter output stream in XSP/Mod_mono can double your
connections/sec (as it did for me)!
It comes down to this method in TextWriter.cs
public virtual void Write (char[] value)
{
if (value != null) {
for (int i = 0; i value.Length; ++i)
Write (value [i]);
}
}
Which I think should look like this
public virtual void Write (char[] value)
{
// No if statement needed since TextWriter is abstract
// the implementing class should take care of checking for null.
Write(value, 0, value.Length);
}
And then in HttpWriter.cs you have the following method:
public override void Write (char ch)
{
Write(new string (ch, 1));
}
Which was being called by the TextWriter method at the top and was causing a
class creation explosion. I'm not sure what's the best way to fix this method
but by calling the Write(char[] c, int index, int count) instead I was able to
double the connections/sec for my app on XSP.

RE: [Mono-list] Mono 1.1.13 has been released.
El mié, 11-01-2006 a las 19:35 +, Bill Seddon escribió: Hi Bill, I have a couple of questions arising from my trials. The first is to ask whether I am the only Windows user of Mono and, if not, am I alone in experiencing problems trying to get applications to run? I think you are not alone, we are producing applications running on top of mono and using Gtk# because we want to run .NET applications on Windows and Linux. I think the main problem you have is that you are using Windows Forms that is still not complete in mono. It's reasonable to ask why someone should be interested in running Mono on Windows when the original .NET is available. Many reasons, first because you can run the same code (we are actually doing so) on windows [1] and linux platforms. Obviously, something could fail. What it could be done is to track and report those failures found so next releases gets better. From our experience, using Mono + Gtk# to produce windows applications is getting more a more stable. From the initial releases we started to use (1.0.5) until now, Mono have increased its quality, and stability. But the point is: how alone is a .NET developer when it gets outside Windows platform? This is critical point to keep in mind if you are going to be a .NET developer. My reason is that Mono applications can be run without an install. .NET requires a lengthy installation (and a reboot with 1.1 SP) that many administrators (if not users) will not consider. Mono can be copied on (or even run from a memory stick). This is a good reason. The second is to ask if there is enough testing being on Windows. The error in the trivial example below results from trying to return the root folder of the drive on which an assembly is located. If there is no real motivation to support Windows, I'd welcome a statement to that effect so that know to look for an alternative solution. Of course, I'd like Windows to be a supported platform but I can understand that it may not be priority for Novell. Maybe it is not a main target for Novell to have a mono platform running on Windows, but I'm not wrong when I say you that there are lot of interest on making mono running on Windows. Cheers!

[Mono-list] Application performance question
This is my first foray into Mono (and C#), and I'm impressed. The developers
have done a wonderful job getting things running. I'm sorry if this question
seems lame or has come up before, but I haven't seen it addressed yet;
hopefully somebody can give me some insight.
I have Mono deployed on a Linux Pentium 4 3.2Ghz system with HyperThreading.
Plenty of RAM. Mono version from Web site as of yesterday, using GMCS.
I'm trying to write a performance-sensitive application, so I'm doing some
load testing at a fundamental level. I wrote the fairly simple application
attached below this message. It's pretty obvious. It just creates a collection
keyed with a ulong, and stores 100,000 items in it. It then references 200,000
keys, changing a field if the entry exists, adding a new entry if it doesn't.
(Net 100,000 changed, 100,000 added.) Finally, it deletes all 200,000 of the
keys.
There are two blocks of code. One uses a traditional Hashtable. The other uses
the generic Dictionary class.
I'm confused. My understanding is that Dictionary is supposed to be much more
efficient here because it doesn't box and unbox. But, when I run the generic
version, it takes 4.18s to run on average, while the Hashtable version takes
2.54s to run. Despite the boxing, the Hashtable runs MUCH faster. This is
running with --optimize=all (doesn't seem to change anything either way).
On a Windows 2000 system with a 3.0GHz non-HyperThreading processor and Visual
Studio 2005, I get what I expect. The Hashtable version still takes about 2.5s
(just slightly faster), but the Dictionary version blows it away at 1.48s,
which is what you'd expect by eliminating the boxing.
My questions is why the Dictionary is so much slower on Linux. Can others
replicate this behavior?
If so, is it a fixable bug, or some other type of problem? I know generics are
part of the IL itself, so perhaps Mono isn't just handling them efficiently?
If that's the case, I can cope with it. I'll just use Hashtable for now, which
provides at least acceptable (and similar) performance across both platforms.
But if I'm doing something wrong, or there's something I can try/fix, I'd love
to know about it.
Regards,
Chad

Mono's Dictionary implementation performs very well under MS.NET 2.0 (about 70% of the performance of MS' implementation).

[Mono-list] Partiting cpanel in fedoracore
Hi Folks I'm running fedoracore 4 on a acer aspire 3610 laptop I have an 80 GB harddrive. ? how do i partition the cpanel scheme. The following partition scheme is recommended: NOTE: Different partition schemes are suitable for different types of hosting. Some servers may require space to be allocated in different ways than others. This recommended scheme is an attempt to provide enough space for many different types of hosting but it is no substitution for real world experience. This partition scheme may need to be varied to suit the needs of your specific setup. /boot 35 Megabytes (Mb) /usr 4096+ Mb (If you have a 60 gig drive try 6144 for /usr, 8192 if you have an 80 gig drive, etc.) /var 1500+ Mb /tmp512+ Mb / 1024 Mb /home grow to fill disk swap2x memory size NOTE: The /tmp directory is a special directory that is required to be writeable by all users and processes on the system. In general, directories that are writable by all users and processes are cause for security concern, however this directory is a special case. To minimize any security impact as a result of having an unsecured /tmp directory, it is recommended that /tmp be mounted on a seperate partition in order to take advantage of the no exec option available under both Linux and FreeBSD. If a separate mount point exists for /tmp, then the installer will verify and potentially remount the partition with the no exec option. Additionally, the installer will ensure that the sticky bit is set on the directory and that the other permissions are correct. If /tmp is not mounted on a separate partition, the installer will create a file system disk image of 512 Mb and mount /tmp on the newly created disk image with the no exec directive. Under most circumstances, 512 Mb is sufficient for the /tmp partition; however, your system may require additional space. It is therefore recommended that you include a separate partition for the /tmp mount point (sized according to your size specification) prior to installing cPanel.

Re: [Mono-list] Help installing mono
Thanks Paul that's great info, very helpful. It would be great if there was a link on the wiki for it, I think it would help a lot of people that go to the mono website looking for compilation help. Paddy Hi, In order to compile mono I had to have a working mcs so I installed the mono-core rpm (I'm running FC4 here). Do I need to remove this package before installing my compiled version of mono? Compiling mono from source can be a bit hectic to say the least and happily, it's now part of FC5. For help, http://www.all-the-johnsons.co.uk/mono/mono-building.html (or is it building-mono - I can't remember!) should have everything you need. Basically libgdiplus, make, make install mono/mcs, make get-monolite-latest, make, make install And that's the core done. What you do next is up to you.
