[IO] Just a little status update.
by Sebastian Redl 28 Sep '07

28 Sep '07

Hi, Some people might remember that I had plans for a new I/O system. Well, today I finished two important milestones, so I thought I'd give a very brief update as to what I was up to. By now, I've designed and implemented: 1) Concepts for reading, writing, mark/reset and tell/seek. 2) Various forms of in-memory sources and sinks, fully tested. 3) Various forms of file sources and sinks, implemented for POSIX and Win32 but as of yet untested. 4) A read-ahead buffer. (Reads a big block and serves further requests out of that.) 5) A chaining system to conveniently build chains out of these components. 6) A type erasure source to hide type complexity. Right now, it is possible to construct a buffered in-memory source (yeah, like that's useful) with this code: source<octet> src( read_mem_unowned(sample_data, sample_size) | buffer<8>() ); This construct a source that reads octets from the memory area at sample_data (which has a size of sample_size units), buffered by an 8-byte read-ahead buffer. The resulting sink uses type erasure to get the short type. Overhead is exactly one virtual call for every operation. If that's too much for you, you can specify the full type of the source: fixed_readahead_buffer_filter<non_owned_mem_source<octet>, 8> If you do that, GCC inlines the entire read operation under -O3 - it all boils down to a few memmoves. (It's a few because buffering in-memory operations only adds overhead without benefit. But whatever.) Conversely, if you wanted to write data, you could do this (not yet implemented): sink<octet> snk( write_mem() | buffer<8>() ); The chaining system is powerful enough to allow the chain stubs to select the appropriate type. The full type of the generated sink is: fixed_write_collect_buffer_filter<mem_sink<octet>, 8> The problem here is getting the data out. I've thought of a system for doing that in such a case, but that's for a separate post. For now, you could just construct the sink separately and then chain it in: mem_sink<octet> data_sink; sink<octet> snk( chain(data_sink) | buffer<8>() ); Now snk holds a reference to data_sink. (So data_sink must stay valid.) And you can get at the sink's underlying vector by calling data_sink.data(). If you don't like the operators, you can use chain() instead: chain(write_mem()).chain(buffer<8>()) Under C++0x, you can get use auto and decltype to get the exact type with less typing with something like this: auto sink_spec(write_mem() | buffer<8>()); decltype(sink_spec)::stream_type snk(sink_spec); Also not implemented, but planned, are text streams. Reading an ISO-8859-1 text file in the finished library would look like this: source< text<utf_8> > src( // A source of UTF-8 text. read_file(filename) | buffer<1024>() | text_decode<utf_8>("ISO-8859-1") ); Things I have to do now: 1) Implement type erasures for sinks and bidi-devices. 2) Make type erasures gracefully handle missing functionality in the underlying devices. That is, if a device can't handle seeking, it shouldn't have to implement no-op or throwing stubs for the seek methods. The erasure should do that. 3) Implement lots more components. 4) Test the file devices. 5) Make writing components easier. Right now, using components is easy, but writing them a bit of a mess due to the chain system. 6) Get started on the text parts. I hope I'll be back soon with more to tell. Sebastian Redl

Continuations in C++
by Daniel Gutson 28 Sep '07

28 Sep '07

Hi Boost community, Despite I´m a newby using Boost, I wanted to ask some users about a very old yet useful idea: the continuations. As an experiment, I made an extremely simple example of how a continuation could look like in C++, and now I was wondering either how can Boost and this concept make benefit of each other: in the case of the concept, what´s the best way to implement continuations using boost, and in the case of boost, whether a new library or extension to functional can be extended to support this feature. The design goals I setted are: - avoid usage of stack and recursion - basic design principles (such as Law of Demeter) compliancy - avoid complex iterative functions for implementing iterative algorithms - provide both a standard way of implementing this, and a platform-specific calling convention with compiler hacks - maximize simplicity In order to test the idea, I made a very simple test implementing a classic factorial using continuations. The ´library´ part of my code is: template <class INFO> class Caller { public: typedef void Continuation(Caller<INFO>& caller, INFO& info); private: INFO& info; Continuation* next; public: Caller(Continuation* ini, INFO& init_info) : info(init_info), next(ini) {} void operator()() { while (next != NULL) next(*this, info); } void stop_calling() { next = NULL; } void set_next(Continuation* cont) { next = cont; } }; /////////////////////////// And the factorial example is: //////////// struct Info { int level; int result; }; void fun2(Caller<Info>& caller, Info& info) { if (info.level > 0) { info.result *= info.level; info.level--; } else caller.stop_calling(); } void fun1(Caller<Info>& caller, Info& info) { info.result = 1; info.level = 5; caller.set_next(fun2); } int main() { Info info; Caller<Info> c(fun1, info); c(); cout << info.result << endl; } Now the three questions: - how can this be best implemented using boost? - is this of enough interest so to be an enhancement of functional, or even a new library? - could Boost provide a mix of calling-convention plus library implementation (compiler-specific) so the above example could be even simpler? I can think of some g++ hacks. Thanks, and my apologies if this isn´t the proper place to post this. Sincerely, Daniel Gutson.

Re: [boost] Proposal: Polymorphic Value Objects

Hello, I am trying to respond on the discussion (in the developer's list) on the indicated topic which were in 3-7 Sept. 2007. Not sure my e-mail will go by the right way (because of some technical troubles). But trying... Mathias Gaunard wrote: > Edd Dawson wrote: > > I'm confused.

These statements (from Mathias Gaunard) are very similar to those which I was trying to popularize in this news group a few years ago and first time even some 5-7 years ago. Though it seemed that I could not convince the majority (in particular that the shared pointers are in general unnecessary). But I am myself still convinced, although admit that shared pointer is acceptable in some rare exclusive circumstances. But, the content of Foo class, which Mathias Gaunard proposed in its first mail, is not clear for me. May be I am behind progress, but I do not know a way to make cloning pointer (or that Mathias' value object, but this seems to be the same in principle) to be non-intrusive. You anyway need virtual cloning function in each class of the hierarchy. I am trying to maintain an Internet page about these things, see http://cern.ch/ismirnov/safetl Regards Igor Smirnov
