[gsoc][signal_network] Signal Network update: improved use of Boost.Fusion, new generic components, enhanced docs and tests

Hello, A quick update on the status of the Signal Network GSoC project (a set of components and connection mechanisms based on Boost.Signals and geared towards dataflow-oriented programming): * Docs The documentation now has more introductory and motivational material. If you don't know what this library is about or why to use it, you can check it the Introduction section out (and please let me know if it's providing you with useful information - it would be very helpful feedback!). The URL is: http://dancinghacker.com/code/signet/ * Boost.Fusion Since changing the internal implementation of all of the components to use Boost.Fusion, I have added support of fused signals in addition to the regular unfused ones. For example, you may choose to transmit the signals the unfused way "as usual" (say via boost::signal<void (float, int &, const string &)>, or you may choose to transmit them fused (say via boost::signal<const fusion::vector<float, int &, const string &> &>). After running some simple timing tests, fused signals tend to be much more efficient in parameter forwarding, although I might be able to cut down the difference some after I look into where all I'm creating unnecessary temporaries in the unfused case. Note: if you want to test the code in the sandbox, note that it includes a small change to the Fusion library necessary if you're using the signet::storage component with a signal that carries a reference (as the timing_example does). If you're using the sort of compiler that complains about multiply defined copy constructors, blame the warnings on me and not the authors of fusion :-) * Components Pretty much all components now offer both a fused and unfused version. Perhaps the most exciting advance (to me) is the introduction of four generic components: * modifier: applies a member function object to any incoming signal and outputs the result * applicator: applies a function object to a member object each time it forwards a signal (say, it increases a counter) * instantiator: instantiates an object from a member object each time it forwards a signal (say, it instantiates a scoped_lock over a mutex) * conditional: forwards a signal if a function object evaluates to true * Tests tests have now been separated into different files, and cover most of the new fused / unfused functionality. all pass on OS X/darwin and Win/MSVC 8.0 The GSoC wiki page might have some more info and some proposed next steps. If you have anything to add, please feel free to update the wiki, or reply here (or off the list if you prefer): http://svn.boost.org/trac/boost/wiki/soc/2007/SignalNetwork All feedback is much appreciated! Thanks, Stjepan

ANNOUNCE: Complexity analyzer for C++
by Eddy Pronk 14 Jun '07

14 Jun '07

GNOCCHI - A COMPLEXITY ANALYSER FOR C++ Gnocchi calculates cyclomatic and the NPATH complexity measures. USES boost.graph boost.program_options boost.filesystem DESCRIPTION It reads the coverage information produced by GCC and determines the complexity of all functions. If code is compiled with -fprofile-arcs or -ftest-coverage (depending on compiler version) GCC creates a .gcno file for every object file. example: gcc -fprofile-arcs -ftest-coverage -c test_input.c ./gnocchi --threshold 4 test_input.gcno outputs: test_input.c:118: mccabe=5 npath=5 test_input.c:89: mccabe=5 npath=16 test_input.c:67: mccabe=9 npath=80 you can find the first release here: http://gnocchi.sf.net http://sourceforge.net/projects/gnocchi Eddy

[uuid] uuid::create() function
by Andy 14 Jun '07

14 Jun '07

Other than the current approach (which I agree is not acceptable), I see 6 alternatives to the uuid::create() function. I believe all of them have been mentioned before. 1. Make the random number generator a static object. Document the function as not thread safe. This will be fast, but easy to use incorrectly (e.g. in a multi-threaded program). 2. Make the random number generator a static object and protect calls to it with a mutex. This is a thread safe solution, but it will be slow because of the mutex. 3. Make the random number generator live in thread local storage. This will be a thread safe solution, but requires Boost.Thread. 4. Use the current seed as the random numbers directly. Will this solution provide 'good' uuids? That is, is this source of random numbers good enough? 5. Create a function object (that has the random number generator as a member) that produces uuids. Is this too complicated? i.e.: class uuid_generator { public: uuid_generator() { engine.seed(get_seed()); } uuid operator() const; private: Engine& engine; }; 6. Create a CAS/lock-free random number generator. This is hard to implement. I am favoring number 4, unless it will not produce good uuids. Then I favor number 5. I guess I am looking for direction as to how to proceed. Andy.

[fusion] unpack into constructor?
by Eric Niebler 14 Jun '07

14 Jun '07

I have a Fusion sequence. I want to create an object of type T using the elements of the sequence as arguments to the constructor. Is there an easy way? I can't tell my looking at the docs. I looked at the stuff in fusion/functional and couldn't find what I was looking for. -- Eric Niebler Boost Consulting www.boost-consulting.com

(I'll explain why the wiki link didn't work in a second). All of the discussion I've seen/participated so far (I didn't look through much of the discussions that occurred before I joined the mailing list in late March) Boost documentation was the most immediate benefactor from the work done here. I signed up for this GSoC project, so in some sense, I'm making what the customer ordered :P... but it is not a waste in any sense of the word. The images produced are vector graphics, making them just as sharp at any level of magnification, the image format is open and robust, the image is written in plaintext (so the images can be indexed by browsers). Image sizes are usually smaller than .jpegs and .gifs, which save on bandwidth. From a web standpoint, that's huge. Also, (probably something I will do after the GSoC project ends), it will be possible for the svg_plot class to parse an existing document. This will allow changes to be made to individual elements of existing plots, which is not something that could so easily be accomplished in a jpeg, gif, or a bitmap! I have nothing against SVG but (for example): > - the picture on the wiki didn't show up correctly event after I installed > a > plugin, I needed to clic on it for them to display on a lank page (I use > IE7, like a majority of users). Also, I took the plugin from adobe and it > seems they don't plan to support it anymore after the end of the year. Adobe will keep the link for the SVG plugin available through the year 2008 (but will stop updating it in the beginning of 2008), and hopefully a year and a half is enough time for me to make this work in another format ;). The Renesis project is also working on SVG plugins, and when Adobe's is no longer available, I expect their solution to be just as good. SVG support was one of the big request items in the IE7 bug tracker before they "temporarily" closed it. They mention SVG when talking about "The Future Beyond IE7" (http://blogs.msdn.com/ie/archive/2006/02/22/537123.aspx) All of their major publicity recently is focused on web standards, but then again, who knows? I didn't embed the SVG image into an <embed> or <object> tag because I have Firefox, and I was hoping I could hold off making an example page with embedded images for a little while. If I embedded it into the page like you would a Flash image, it would show up fine for you. I'll set up an example page on my @ tcnj.edu site soon (as in tonight or tomorrow), and you will see the images in their full glory. - If I want to put the svg in a latex document, I would need to convert it > to ps/eps.

The whole point of GSoC is to get people interested in contributing for communities, and I'd like to keep going after this is done. Everybody I deal with has been helpful and intelligent. I intend to extend these headers and make them usable by the broadest category of people I can, but it'll be a while before I get to these use cases. (I'm only one person!) When I start doing that, I may change the architecture, but for now it's convenient to deal with it in an inherited manner (as, after all, a svg_plot "IS A" svg document). At the current point in time, I'm not considering putting it up for final review immediately after GSoC ends, because there will still be a lot I'll want to do with it that I couldn't pull off in 3 months, so if and when it is accepted into Boost, it will have addressed a lot of your concerns. You brought up some very important, big-picture points, and I thank you for doing this so that I can consider these things early instead of later in the project. Lastly, please excuse my poor English. I don't use English very often. I understood everything you said.. no worries! Jake
