2.6 preview 1

[Andrew Jorgensen-4]

The first preview build of 2.6 has been published to http://mono.ximian.com/monobuild/preview/download-preview/

The windows installer in this build is known to contain a number of problems, including but not limited to:
* Has an older build (2.4.x) of gluezilla
* Does not contain mono-tools (monodoc browser, gsharp, gendarme, etc.) or gnome-sharp
* Is larger than it was previously despite missing mono-tools, etc.

We are working through these problems but felt that it was more important to get the build (and the preview tarballs) out into your hands.

SLE_10 and openSUSE_10.3 binary packages have been dropped (mono-tools now requires a more recent gtk than available in SLE_10 and 10.3 will be end-of-life around the time we publish 2.6-final).

The DRAFT release notes are here: http://www.mono-project.com/Release_Notes_Mono_2.6

Small typing error on the "Release Notes"

Users of mkbundle can now pass runtime options to the generated
executable by setting the <codet>MONO_BUNDLED_OPTIONS</code>
environment variable.

Where is "<codet>" it should be "<code>", I think.

Is the Mono for Windows installer bigger now because it includes the mono.dll and mono static libraries like libmono.a which non-embedders do not need?

I think maybe there should be two installers for mono on windows.

1. Normal. (Mono/Gtk+/Gtk# Runtime and Compilers and Tools).
2. Embedded.  This would require the first installer. The embedded can include the extra mono.dll and libmono.a and other libraries needed for embedding mono.  This would also be the version you would need to build mono or gtk# from source.

This will make the Normal installer smaller.

Mono.dll is required by the Windows build, so it cannot be omitted.
Libmono.a is of no use under Windows and it should not be distributed
anyway. Mono.lib (I believe it's still not distributed) would be just
a tiny import library.

Has the Task Parallel Library been performance tested on OSX? I've been having a tough time getting any kind of performance out of my threads on the Mac+Mono platform. Maybe this is the solution?

I never heard of it tested under OSX.

Unlikely. I mean this in a constructive way, but the problem is more likely just a bad threading implementation. Altering how you split data up between threads and/or how you manage the threads would likely be the best way of improving performance. Performance of Mac + Mono should be very close to Linux + Mono. If you're seeing a huge difference in the exact same code it might be worth filing a bug.

Hey Alan,

I understand. I've been through the algorithm and it's very sound. It screams on Microsoft .net, runs nicely (but a little slower) on Mono runtime and Linux. Bogs down like crazy on Mono + Mac. I have a sneaky suspicion it's the way the calling thread is waiting for the worker threads to finish (WaitHandle.WaitAll(...)). Maybe Mono's Mac implementation of this is very inefficient?

-L

I'm going to prepare a compact test case that illustrates the behavior.

I haven't seen much chatter (on mono-devel-list) recently about the 2.6
release.

I wondered, is it would be possible to get a fix for
https://bugzilla.novell.com/show_bug.cgi?id=495957, a regression from 2.2,
into the 2.6 release?

Many Thanks!
Anthony

I just applied the patch to mono-2-4, mono-2-6 and trunk.

[Erven Rohou-2]

Hello,

I tried to build the preview 2.6 on Sparc and PowerPC. It failed on both,
apparently because of problems in GC, but for different reasons.

The problem on powerpc looks similar to
https://bugzilla.redhat.com/show_bug.cgi?id=494026 in Mono-2.4.

I may well be missing something...
