I'm going to continue working on it in the spring, so who knows what'll happen? I would submit a proposal to continue working on it during the summer, but I don't think I can participate in another GSoC (I graduate as the summer starts).

The precise GC is going to continue to hang until it can be tweaked to be as fast or faster than the conservative GC we have now. Me working on it has effectively stalled because school takes up much of my time and I'm still pretty lacking in experience with garbage collection. That's pretty much why I'm doing the study.
Independent Study at my university using D
Something pretty exciting happened yesterday: I registered for an independent study to build a basic garbage collector in D at my university. This is exciting for me because I really enjoyed the work I did during the last GSoC, so I'm hoping to learn more about garbage collection and contribute to D's garbage collector more in the future. This is especially exciting for the D community because my professor wants me to give a presentation at the end, which will expose more professors and students to this language. I don't have many details about it, but I'm hoping to have it recorded so it can be posted.

However I must have either failed to hit 'save' or the save itself failed (I will assume the later since that makes me look less incompetent). To make matters worse I got an automated email from Google at 3am the morning of the deadline warning me, but since I had a particularly busy day at work on the 9th I didn't get a chance to check my email until shortly after noon on Feb 9th. At which point it was too late. So I want to apologize to the D community for this mix up on my part, and in particular to those who invested time in helping get ready for this year's GSoC and to you students who were looking forward to applying. However, for anyone who did work on the Ideas page that can at least be re-used and we now have a much fuller list. Regards Craig Not sure how viable this is, but would the D Foundation be able to do its own version of the Summer of Code? The D Summer of Code? Depending on how much money it has, it could pick some students that were working on proposals and pay them what Google would have paid them based on performance like in the real GSoC.

My open PR for the actual inclusion of the precise GC is here: https://github.com/dlang/druntime/pull/1603 So what's its current state, how is it different from the version Rainer had years ago? Is stack scan precise? Are closures scanned precisely? What about unions? The version in the pull request is not different from the one Rainer presented at all. It's actually the same one, just updated with what has been changed in druntime recently and my attempts at making the marking phase faster. It isn't any faster, but I didn't realize this due to benchmarking differences on AMD and Intel platforms. I should correct this in the next couple of days and performance can be assessed again. Scanning the stack would require some support from the compiler. Precisely scanning unions is tricky since they could mix pointer and non pointer types. I'm not sure about closures. If I've done anything with closures I'm not aware of it. I have yet to actually work with the compiler, but in the future I will have to I suppose. We'd be happy to see some overview of this version, what it does and how it succeeds (or fails). It is essentially in a similar state that it was when Rainer presented it at DConf2013. I spent a lot of time doing research on techniques to improve its performance and I did start working on a sort of proof of concept for some of these ideas, but implementing it in a cohesive way would have required a lot more than was possible in the GSoC timeframe and it just didn't happen. It's pretty late for me here, but I will definitely explain more about some of these things later. It's essentially stuff that I do on my own time.
[GSoC] Precise GC
Hi everyone, I know I'm super late to the party for this, and sorry for that. While my work on the precise GC didn't go as planned, it is closer than it was to be getting merged. My open PR for the actual inclusion of the precise GC is here: https://github.com/dlang/druntime/pull/1603 Even though GSoC is over and it isn't quite ready to be merged, I will still continue working on it in the hopes it'll get in. I have about a month until school starts up again, and I'm going to try to get it merged before that point. Through the work I did and the research of a couple of GC topics, I discovered that I really enjoyed working on the garbage collector and I plan on continuing that. I was recently accepted to the University of Washington's computer science program and I am currently working on getting some independent study classes set up for future GC work. Once I have some better programming chops I'm hoping to help take D's GC to new heights. Thanks to Martin Nowak and Adam Wilson for being my mentors and for keeping me going, to Rainer Schuetze for doing a significant portion of code review, and to the D community for giving me the opportunity to do this work.

GSoC 2016 - Precise GC
Hi everyone! I'm a little late to the party as far as my announcement goes, but I have been busy reading code and doing research for my project. I was selected for this year's GSoC to implement a Precise GC, but I'm also planning to remove the lock on allocations as outlined in my proposal: https://drive.google.com/file/d/0B-UTFTbYro4vV0ljMUlSTEc2eEU/view?usp=sharing My repository for the code can be found here: https://github.com/Jebbs/druntime I will be posting of my progress in this thread throughout the course of the summer, but right now I am mainly focusing on familiarizing myself with all of the GC code since there is quite a lot of it. You will probably see me pushing some updates to documentation between now and when GSoC officially starts, but I hope to have already started making progress before then. I'll do my best to not let you all down!

DSFML reaches version 2.1
It is my pleasure to announce that DSFML hit version 2.1! This version has been a long time coming, but this represents a huge milestone for DSFML (and for me!) DSFML(along with its backend DSFMLC) is a binding and a wrapper for SFML - the Simple and Fast Multimedia Library. It does input(mouse, keyboard, joysticks/gamepads), audio (buffered playback, streamed playback, recording), networking(tcp/udp sockets, ftp, http), window and OpenGL context creation, and simple 2D graphics using OpenGL (sprites, text, shapes, shaders, and vertex arrays). Currently works on Linux, Windows, and OS X. Reasons that this took so long was: - Many bug fixes - Finally passed all included unit tests - Things make more sense - Created a website - Added documentation - Added tutorials - School's a bitch Visit the website at http://dsfml.com to view tutorials, documentation, forum, and downloads. Just a heads up, I have never gotten a project to a point like this. I have never had to put a website or tutorials together for anything, and this is the first "real" release. I'm sure some things don't make as much sense as I think they do. Go easy on me ;) Plans for the future: - Make things more idiomatic to D - Update to most recent version of SFML - Better everything (tests, documentation, tutorials, website) Check it out, have fun, and most importantly let me know if you have issues! https://github.com/Jebbs/DSFML https://github.com/Jebbs/DSFMLC http://code.dlang.org/packages/dsfml

Apparently MinGW doesn't like to do static links to these libraries? Maybe I'll rebuild it with VC instead. Digging a bit, it looks like this happens in the CMake stuff. Basically, in normal SFML, the CMake file doesn't allow you to statically link to the std libs if you're building a .dll. I felt like with D we don't care as much about that, so I disabled the check. As far as I can tell it should work fine when built with VC(it forces /MT), but nothing special happens with MinGW so it still links dynamically to everything. I think I can fix it to work automatically, but for now I'll instead simply redo the packages to include those files. Thanks for catching that.

If the application exits somewhat cleanly (through return from main or even a thrown exception in D), it will run, though I'm not sure if that's guaranteed or just an implementation convenience. However, if the application exits differently, they won't necessarily be run. For example, a Unix signal terminating the process skips all the D cleanup tasks. Often, this doesn't matter because the operating system will clean up a lot of resources anyway. But if you are using something like shared memory with another process, or expect a file to be written to in a destructor, you'll find those things never happen. I had this problem once in simpledisplay.d. When it died by ctrl+c, the unix SIGINT was sent, and that skipped the destructors for shared images. As a result, the system eventually ran out of shared handles and most GUI programs wouldn't start up anymore until I cleaned it up some other way. Yikes, that's good to know. Still, I feel like it could be worded a little better in the docs and anywhere else they are talked about. I feel like it is just far too ambiguous.

Upcoming changes to DSFML
Hey all, I have been working on a lot of things for DSFML, namely getting it updated to 2.1(which is the most current official version). Some of these changes will break existing code in a couple of places, so I wanted to make an announcement before I started pushing the new code into the repo's master branch. This announcement is mainly targeted at DUB users. Please be aware that it will update your local copy of the repo and that might start breaking things with out your realizing. To prevent this from happening, and to allow yourself to continue with your DSFML projects like nothing is happening, simply change your DSFML dependencies in your dub.json to use ~2.0 instead of ~master. I'll wait a couple of days to actually commit the code just in case. I'm really excited about this upcoming release of the project as it improves the stability of the library and fixes many problems. As always, feel free to email me or open up issues on github if you have any problems with DSFML. project: https://github.com/Jebbs/DSFML email: dehaan.jerem...@gmail.com
