digitalmars.D - DustMite updated

I played with some algorithms today and got about a 7x 
improvement in reduction time for my test case. The data is now 
arranged into a binary tree, and the progress indicator was 
changed to reflect that. Let me know if I broke anything in the 
process.

No new features have been added. Still thinking about how to 
handle lists.

I can't test for these easily (I wish DMD on Windows had -m64 working with -o-).

As a Windows guy on a 32-bit machine (yes, yea, I know, I know, "that's old", "you should upgrade", etc), I always test 64-bit (on a 64-bit machine that I at least have access to) by using a 64-bit Debian 6 LiveDVD with USB persistence: http://www.linuxquestions.org/questions/debian-26/live-dvd-but-save-to-usb-913698/#post4526688 I use that to do 64-bit testing right before any release. Not nearly as nice as -m64, but it works well enough for me. It sucks that you can't run a 64-bit OS in a VM without hardare virtualization (which many Intels don't have), even on a 64-bit machine with a 64-bit host OS (Hmm...or is that restriction only on 64-bit machines with 32-bit host OSes...? I forgot...).

I pushed out another large update today[1]. Changes include 
comma-separated list support (no more stray empty modules), a 
better progress indicator, a more useful/intuitive --noremove 
option, several bugfixes, as well as a large internal overhaul 
and the arrival to the bottom of my to-do list :) So, I consider 
DustMite completed for the moment.

It's reproducible in 2.058 too. Reduced test-case: http://paste.pocoo.org/show/560891/ That ran really really fast compared to older versions of dustmite. Great work Vlad. :)

Just play around with AA's a bit and you'll run into lots of them. ;-) Especially unusual AA's, like unusual key types.

Oh don't worry, I'm all too familiar with ICEs. :) They do mostly show up when doing metaprogramming and not that often in regular code.

I ran into an ICE today and decided to try DustMite. I couldn't compile it though: chad Hugin ~/dprojects/dustmite $ dmd dustmite.d dsplit.d dustmite.d(873): expression expected, not '>' dustmite.d(873): found 'regex' when expecting ')' following template argument list dustmite.d(873): semicolon expected following auto declaration, not ')' dustmite.d(873): found ')' instead of statement DMD32 D Compiler v2.057 on Gentoo Linux If it's because my compiler is a version behind, then don't worry about it too much. I haven't updated because issue 5278 (http://d.puremagic.com/issues/show_bug.cgi?id=5278) makes it a pain for me to upgrade the dmd.

 If it's because my compiler is a version behind, then don't worry about
 it too much.  I haven't updated because issue 5278
 (http://d.puremagic.com/issues/show_bug.cgi?id=5278) makes it a pain for

If you find any problems with the ebuilds, don't hesitate write an email to me for DMD2 or Julian "hasufell" Ospald for DMD1. (See http://overlays.gentoo.org/proj/sunrise/browser/reviewed/dev-lang/dmd/ChangeLog ) for the email address. They are taken from the discontinued d-overlay and updated to meet Portage ebuild writing standards. We may be able to sort out some Gentoo specific issues for already released versions of DMD via patches. I also keep the three most recent releases in the tree, so you can downgrade in case of problems. -- Marco
