You're welcome. I hadn't done it before because I couldn't figure out a 
reasonable way of implementing it.

I don't know if you are talking about DMD being in a public repo, the
contract inheritance or both. But anyway, I'm glad you could finally do
both =)

Thanks Walter.

;)

Now, thanks to the public svn we can track changes easily. This will help 
development of gdc too!

Btw today Michael merged dmd 1.035 and i'm close to finish dmd 2.015

See you.

I'm glad you guys have picked up gdc.

There are some tricky bits to doing contract inheritance, I hope gdc and 
ldc don't have trouble with it.

It's outlined in the code comments, but it's implemented by making the 
contract code a nested function. The overriding function calls those 
nested functions of the overridden function(s). In order for this to 
work successfully, the 'this' pointer and the stack parameters must wind 
up in the same relative position on the stack.

I'm still none the wiser about why it absolutely has to be done like 
this instead of the simpler solution I proposed years ago.  But in any 
case, thank you for finally getting round to it!

Can you refresh my memory?

(The nested function approach is fairly simple in terms of lines of code 
to implement.)

Seems straightforward to find to me, but here it is:

http://www.digitalmars.com/d/archives/digitalmars/D/31595.html


 (The nested function approach is fairly simple in terms of lines of code 
 to implement.)



I can imagine how it works now.  Essentially it's a function that can 
act as a nested function to the function for which it is originally 
defined or any override of it, which works since a nested function is 
really just a function with a pointer to the outer function's stack 
frame as a parameter.  Correct?

BTW I just rediscovered this old thread

http://www.digitalmars.com/d/archives/digitalmars/D/9775.html

which is making me think we probably ought to enable contracts on 
bodyless functions some time.

'this' pointer could be passed as a regular argument just like stack pointer.

Actually, there are no D2 compilers for 64 bit. GDC's support for D2 is 
very minimal, I don't know how it compares to LDC's, but I'd guess they 
were about the same (GDC might be slightly further ahead actually, I've 
never tried it). Either way, DMD is pretty much the only choice for a D2 
compiler currently.

Now that DMD is under version control it should be fairly easy for me to 
adapt the automated build system used for ldc for dmd. I can set it up 
to automatically build dmd after a commit, and run dstress/build popular 
projects and libraries, even package up dmd for "Nightly" builds and 
maybe even post the results to the D newsgroups/IRC channels.

If you'd be interested to see this Walter, let me know what exactly you 
want automating/how and where you want results and I'll see about 
setting it up for you.

The problem is if some package fails, then I have a large debugging 
problem trying to figure out unfamiliar code.

Or it could just inform the owner of the lib and they can cut out a test 
cases or even do most of the detective work for you.

What exactly would you like setting up? Currently I'm thinking:

* Automated builds of dmd 1 and 2
* Automated builds of druntime, phobos and tango
* Automated DStress runs
* Automated dmd test suite runs (if you're willing to provide me access 
to the test suite)
* Automated builds of more popular projects from dsource (with 
permission from the maintainers obviously)

Is there anything else you want?

I also need to know how you would like results to be reported. Would you 
like them to sit on a web page with an RSS feed, email the results to a 
specified list of email addresses, post to the nextgroups, post to IRC?

I suggest setting it up to email the maintainers of the packages being 
compiled any problems with compiling them.

I think it would be best to have a newsgroup/mailing list/RSS for this.
At least being able to see the result in a website.

I'm very curious, I'd love to be able to see the results of this automated
tests =)

It's open to everyone and don't spam the mail folder
in times of broken code.

I think that'd be fantastic. It'd be helpful if you could at least get 
dstress to run after the main releases. The dstress test page from LDC 
doesn't seem to operate any more.

http://www.incasoftware.de/~kamm/ldc/tests/index.html

I'd really like to see the results for the latest DMD, almost all of the 
  "ERROR" (segfault/ICE) bugs should be fixed now.

Walter doesn't necessarily ever have to look at it, but it'd be good as 
a pre-release check.

There are quite a few incorrect dstress tests. I've been making tickets 
for them as I find them.

This page gets updated manually by Christian as he feels fit. For more 
up to date pages, see:

http://ldc.octarineparrot.com/x86-32/web/
http://ldc.octarineparrot.com/x86-64/web/

For x86-32 and x86-64 respectively (these aren't completely automated 
yet, they require me to run a command to generate them every now and 
again... I'll sort this out when I get it set up for dmd). They still 
compare to dmd 1.045 as ldc still uses the 1.045 front end (I believe 
there were some regressions from 1.046+, not sure on the current status 
of this).

Agreed.

I believe Christian is the maintainer for the dstress project on 
dsource, he should be able to give you commit access if you have patches.

That's true. I've updated the front page with my email address and the

LDC2 does not work at all on my 64bit GNU/Linux box, while GDC works

Sure, old version of D2 is supported so many cool features are missing,  
that is why I hoped some more up-to-date version of GDC will soon be  
released.

D is loosing in popularity these days. Personally, i think one of the  
major reasons is the stale development of GDC. (Yes I am aware of the LDC  
project, but it is quite new one, and lacks working D2 support).
