[Mono-dev] [PATCH] CodeGenerator/CodeDom classes
Hi monkeys, Could somebody please review my patch for the System.CodeDom classes? This is the fourth time I'm posting this and nobody provided any feedback so far. I'm sending this via my gmail account now, in case my previous mails did not reach the list subscribers (they _did_ reach the list itself). I've created a enhancement bug which contains the code: https://bugzilla.novell.com/show_bug.cgi?id=356657 ChangeLog entries are included, all unit tests pass. Please review (or at least comment...) - Juraj ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

[Mono-dev] Using IDispatch as an Argument in Invoke.
Hi, I've embbed mono into an application that Im working on. The function in my Assembly has a IDispatch pointer as its first argument, how can I pass this value throught to my mono class? If it cannot be done, is there any timeframe?

[Mono-dev] System.Collections.Generic.Dictionary`2 bug?
Hi,
I got he following problem: When i change the values of a Dictionary`2
enumerating the keys i get an exception. for example:
Dictionarystring,int test = new Dictionarystring,int ();
test.Add (foo, 2);
test.Add (bar, 3);
foreach (string key in test.Keys) {
test [key] = 5;
}
throws:
System.InvalidOperationException : out of sync
at System.Collections.Generic.Dictionary`2
+Enumerator[System.String,System.Int32].VerifyState () [0x0]
at System.Collections.Generic.Dictionary`2
+Enumerator[System.String,System.Int32].MoveNext () [0x0]
at System.Collections.Generic.Dictionary`2+KeyCollection
+Enumerator[System.String,System.Int32].MoveNext () [0x0]
It looks like the KeyCollection enumerator uses the Enumerator of the
Dictionary which might invalidate when i change the values, but is this
intended?
MSDN says:
«The foreach statement is a wrapper around the enumerator, which allows
only reading from the collection, not writing to it.»
So do i have to understand this in the way that i am also not allowed to
change the values ehen enumerating the keys?
If it is a bug, please tll me i will then try to fix it, if not i will
change my code to use a copy of the key list or something.

Re: [Mono-dev] Questions About Mono in Second Life
Hello, I do not speak for Linden, you should direct these questions at them, but here are some guesses: May I ask questions about Mono in Second Life as below? 1. Which language will residents input for script after Mono is applied ? LSL. 2. I know LSL still works. But can it still be inputted as a supported language? Yes, your LSL code now gets JITed using Mono instead of being intepreted. 3. Do residents have to download software for Mono ? Or just input the language Mono supports as simple as what LSL does currently. They can keep doing it in the same way; My understanding is that you only need to check a checkbox in the SecondLife viewer, and your LSL script will be executed with Mono instead of the current LSL engine. 4. Is the language Mono supports more difficult than LSL and thereby most of residents can't work well on it? Currently only LSL is supported; I believe they plan on opening up SecondLife to new languages in the future. 5, May I understand the language is still LSL for residents, but the virtual-machine changes into Mono ? Its an internal change that offers more speed for now; More features will be available in the future. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
[Mono-dev] Monodevelop doesn't run...
Hi to all,
I'm new to mono and monodevelop.
I've just installed them on my Ubuntu 7.10 from sources:

Everything seemed to be ok, but when I try to run monodevelop, it fails with
this message:

[Mono-dev] Problems getting mono running on a Asus Eee
Note: I'm a linux newbie and I hope this is on topic for the list and apologies to folks that have seen this already in the forums at gotmono.com Hi, I've been trying to get mono working on an Asus Eee. I can use the Xandros repository versions of mono without a problem, but I'd like to move onto 1.2.6 using a tarball compile with the --with-tls=pthread. Prior to running 'make install' I have removed the Xandros version of mono with apt-get remove. The first thing I do with mono after a reboot works fine, the second hangs, if I set the MONO_LOG_LEVEL to debug then run a simple helloworld.cs app using mono 'helloworld.exe' then the first time the trace looks like this: [snip] Mono-INFO: Config attempting to parse: '/usr/etc/mono/assemblies/mscorlib/mscorlib.config'. Mono-INFO: Config attempting to parse: '/home/user/.mono/assemblies/mscorlib/mscorlib.config'. Mono-INFO: Assembly mscorlib 0x821ae80 added to domain helloworld.exe, ref_count=1 [snip] If I run it a second time the trace looks like this just before it hangs: [snip] Mono-INFO: Config attempting to parse: '/usr/etc/mono/assemblies/mscorlib/mscorlib.config'. Mono-INFO: Config attempting to parse: '/home/user/.mono/assemblies/mscorlib/mscorlib.config'. ^-- shell hangs here Starting a new instance of the shell doesn't fix the problem, but I can run 'make check' which works but it seems to do a lot of messing with PATHS and stuff and I'm not sure which bits of the mono runtime it's using. I'm a complete linux newbie so I'm struggling a bit to figure out what to do next and how I should go about debugging this with gdb?

[Mono-dev] Compiling, running mod_mono on OS X (10.5.1)
I've been trying for 3 1/2 days to get mod_mono up and running on my MacBook running Mac OS X 10.5.1 (detailed specs at end of message). The install appears to run smoothly, and files are definitely written to the disk, etc., but when I go to restart Apache, I receive the following error: 2/1/08 8:41:38 AM org.apache.httpd[7391] httpd: Syntax error on line 492 of /private/etc/apache2/httpd.conf: Cannot load /opt/local/apache2/ modules/mod_mono.so into server: dlopen(/opt/local/apache2/modules/ mod_mono.so, 10): image not found I read a message somewhere about this same message on PPC Macs, but I never found a resolution. And mine is definitely Intel. My own investigations have found that the install script creates a mod_mono.so in the correct folder (/opt/local/apache2/modules), but that it's a symlink/alias to mod_mono.0.0.0.so, which does not exist. I have already (apparently successfully) installed and run mono and xsp. At least, they report that they were installed correctly and are actively listening, etc. I have tried installing the DarwinPorts version (which is older and never actually completes), as well as the manual install.

So, I do not see where I am wrong and not following the code convention.
Then I can't help much.
All the expression class contain readonly things with only getter an
nothing
to set it. In all other expression inherited class we have the same
behaviour and same system. So it is quite easy to add what is missing.
And you managed to propose wrong constructors in the patch you sent to

Anyway, I don't see much interest in pursuing this conversation.

[Mono-dev] Lang Theory Question
I'm a sucker for syntactic sugar. There is one little trick which I've
been trying and failing to do - it turns about to be impossible - but
as a language theory exercise, I thought I'd work out what would be
needed to let me do this thing.
One nice thing about nullable types is the non-standard behavior of
the assignment (=) operator. For example:
int? val = 5;
val = 6;
is shorthand for:
Nullableint val = new Nullableint (5);
val.Value = 6;
I am working with a struc similar to Nullable and I'd like to be able
to use the assignment operator in a similar way. Unfortunately, the
assignment (=) operator cannot be overloaded. The struct, SchemaEntry,
is used to store and retrieve configuration data from some backend
(gconf, the Windows registry, an XML file, c.). Here's essentially
how I currently use the struct:
SchemaEntryint entry = new SchemaEntryint (DbVersion);
int version = entry.Get ();
if (version 2) {
MigrateDb ();
entry.Set (2);
}
I would like to be able to do the above with this code:
SchemaEntryint entry = new SchemaEntryint (DbVersion);
int version = entry;
if (version 2) {
MigrateDb ();
entry = 2;
}
This is how I envision writing the code to allow me to do that:
public struct SchemaEntryT
{
public SchemaEntry (string name)
{
//...
}
//...
public static SchemaEntryT operator =(SchemaEntryT entry, T value)
{
entry.Set (value);
return entry;
}
public static implicit operator T (SchemaEntryT entry)
{
return entry.Get ();
}
}
This is obviously not possible because C# forbids overloading =. A
potential problem is as follows:
SchemaEntryint entry = 5;
As you can see in the outline of SchemaEntry above, there is no
parameterless constructor, so this code is clearly problematic. One
solution to treat this as:
SchemaEntryint entry.Set(5);
and throw a use of unassigned variable compiler error. If you wanted
to allow this syntax (in the way that Nullable uses this syntax), you
could allow for overloading of the new operator like so:
public static NullableT operator new(T value)
{
return new NullableT(value);
}
Another problem is allowing overloading assignment between the same type:
public class Foo
{
public static Foo operator =(Foo f1, Foo f2)
{
f1 = f2; // recursive fail
}
}
I can think of a few possible solutions:
1) Require that the two parameters to the overload function be of
different types. This would still allow the safe use of generics (as
with SchemaEntry).
2) Stipulate that any use of the assignment operator inside of an
assignment operator overload function will perform a standard bitwise
copy.
3) I had other solutions, but I actually think these two cover it pretty nicely.
I prefer solution 1. I've given it a little think and no problems jump
out at me. So I post this to solicit counter cases. If you'd like to
tell me that this kind of syntax is a) confusing, b) unnecessary, c)
evil, d) all of the above, have at me, but I am more interested in
disastrous corner case in my above proposal. And if you too yearn to
save yourself precious parenthesis, feel free to chime in too!

[Mono-dev] Mono 1.9 (r94604) Stalls on Exits?
I've compiled Mono 1.9 r94604 from source on an ubuntu gutsy amd 64 machine today. I've encountered some wierdness where my application will stall on exit, sometimes up to 10 seconds, sometimes not at all. At various times I've seen this message after/while it manages to exit...: ./a.sh: line 3: 22356 Real-time signal 1 mono a.exe $@ Does this make any sense? Naturally if I call Application.Exit(0); the application exits cleanly EVERY TIME. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
