[Boost][Reflection] [Extension] Update
by Jeremy Pack 12 Feb '08

12 Feb '08

Hi All! The proposed Boost.Extension and Boost.Reflection libraries are back in active development, after a few months of inactivity. For those wishing to follow their progress, I am tracking the status of the libraries at: boost-extension.blogspot.com I've posted docs as well (also linked from the website): <tr_1202836009932>Boost.Extension docs<http://redshoelace.dlinkddns.com:9080/boost/doc/extension/index.html> The Reflection docs only have one useful section, detailing interoperability between Boost.Extension and Boost.Reflection: Reflection/Extension interoperability<http://redshoelace.dlinkddns.com:9080/boost/doc/reflection/boost_reflection…> It should contain enough information to show basic usage of the library. For more detailed code, you can look in the /test/ and /examples/ directories for both projects in the Subversion repository: http://svn.boost.org/trac/boost/browser/sandbox/libs/extension/ http://svn.boost.org/trac/boost/browser/sandbox/libs/reflection/ These libraries provide shared library (dll, so, dylib etc.) loading, and instantiation of classes in those libraries. Boost.Extension can load any class that inherits from a base class in the main module, whereas Boost.Reflection can load arbitrary classes. Feel free to try out the code in the sandbox. Current work: - Reflection documentation - Examples of using Extension with Boost.Functional/Factory - Advanced options for calling functions that have been reflected - calling functions when the function signature is unknown. If you have questions or feature requests, let me know. Thanks! Jeremy Pack boost-extension.blogspot.com

Review of Logging library begins today February 4th
by Gennadiy Rozental 12 Feb '08

12 Feb '08

The formal review of Logging library, proposed by John Torjo, begins today and will run till Feb 13: *Description/Motivation:* Applications today are becoming increasingly complex. Part of making them easier to develop/maintain is to do logging. Logging allows you to see what happened in your application. It can be a great help when debugging and/or testing it. The great thing about logging is that you can use it on systems in production and/or in use - if an error occurs, by examining the log, you can get a picture of where the problem is. Good logging is mandatory in support projects, you simply can't live without it. Used properly, logging is a very powerful tool. Besides aiding debugging/ testing, it can also show you how your application is used (which modules, etc.), how time-consuming certain parts of your program are, how much bandwidth your application consumes, etc. - it's up to you how much information you log, and where. *Online docs:* http://torjo.com/log2/doc/html *Download:* Package for download is available here: http://torjo.com/code/log2.zip (version v0.22.7 is targeted for review) or you can get the library from svn http://svn.boost.org/svn/boost/sandbox/logging/ *Compilation:* The Boost Logging Lib has been tested with the following compilers: VC 2005 VC 2003 gcc 3.4.2 gcc 4.1 Compiling using bjam is covered here: http://torjo.com/log2/doc/html/miscelaneous.html#misc_bjam What to include in Review Comments ================================== Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. Here are some questions you might want to answer in your review: * What is your evaluation of the design? * What is your evaluation of the implementation? * What is your evaluation of the documentation? * What is your evaluation of the potential usefulness of the library? * Did you try to use the library? With what compiler? Did you have any problems? * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? * Are you knowledgeable about the problem domain? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. Gennadiy Rozental - Review Manager -

[logging] lots of warnings
by Phil Endecott 11 Feb '08

11 Feb '08

I get lots of warnings when I compile code using the logging library with g++ 4.1.3 with -W -Wall. I think they're all "class with virtual functions has non-virtual destructor", e.g. /usr/local/src/boost-logging/boost/logging/detail/logger_base.hpp: In instantiation of ‘boost::logging::detail::default_cache_keeper<boost::logging::detail::cache_before_init<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >’: /usr/local/src/boost-logging/boost/logging/detail/logger_base.hpp:126: instantiated from ‘boost::logging::logger_base<boost::logging::gather::ostream_like::return_str<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> > >, boost::logging::default_, boost::logging::override>’ /usr/local/src/boost-logging/boost/logging/detail/logger.hpp:214: instantiated from ‘boost::logging::logger<boost::logging::gather::ostream_like::return_str<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> > >, boost::logging::default_>’ Session.cc:203: instantiated from here /usr/local/src/boost-logging/boost/logging/detail/logger_base.hpp:53: warning: ‘struct boost::logging::detail::default_cache_keeper<boost::logging::detail::cache_before_init<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >’ has virtual functions but non-virtual destructor /usr/local/src/boost-logging/boost/logging/detail/logger_base.hpp: In instantiation of ‘boost::logging::logger_base<boost::logging::gather::ostream_like::return_str<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> > >, boost::logging::default_, boost::logging::override>’: /usr/local/src/boost-logging/boost/logging/detail/logger.hpp:214: instantiated from ‘boost::logging::logger<boost::logging::gather::ostream_like::return_str<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> > >, boost::logging::default_>’ Session.cc:203: instantiated from here /usr/local/src/boost-logging/boost/logging/detail/logger_base.hpp:126: warning: ‘struct boost::logging::logger_base<boost::logging::gather::ostream_like::return_str<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> > >, boost::logging::default_, boost::logging::override>’ has virtual functions but non-virtual destructor These are too verbose to ignore, even if they are harmless. Can they be fixed? Phil.

interest in run-time typechecked replacement of void pointer ?
by Matus Chochlik 11 Feb '08

11 Feb '08

NOTE: Code to be discussed can be found in the Boost Vault in directory Memory/RawPtr, archive rawptr-draft-0.xx.zip (where xx is the current version of the draft) Shorter version: A class raw_ptr as a replacement for plain void* [void pointer] is suggested that does run-time typechecking in a similar way as Boost.Any does but follows syntax of void* as much as possible. Thus in the ideal case allowing find-replace substitution of void* in code without introducing syntax errors. A new cast type; raw_cast is suggested to replace static_cast when casting from untyped to typed pointer When a bad cast is detected (at run-time) a compile-time defined policy (by default calling of abort()) is executed. Longer version: Even though the use of untyped pointers in cpp applications is discouraged and can be usualy avoided by using templates or by other means, (like Boost.Any) there are situations where an untyped pointer ''must be used'' or is the best option. The disadvantages are obvious, by using the void* we are deprived of all information about the type the pointer points to. This can lead to hard to find, persistent bugs in larger programs. However in many applications that resort to using untyped pointers the code follows pattern shown by this pseudo-code: typedef <some-type> T; T* ptr_x = acquire_ptr_to<T>([argument-list]); ... void* raw_ptr_x = ptr_x; store(raw_ptr_x, key_to_x); ... T* ptr_x_2 = static_cast<T*>(retrieve(key_to_x)); use(ptr_x_2); i.e.: 1) Create or get a pointer to an instance of a known type. 2) Store or pass the address of the instance by the means of an untyped pointer. 3) Let the code logic to determine the correct type and cast the pointer back by the means of static_cast Even if the logic behind points 1) 2) and 3) is consistent subtle bugs can be introduced that may cause undefined behavior or application crashes. The proposed raw_ptr class that does the typechecking in a similar way as Boost.Any does and allows to detect bad casts from void* to typed pointer and act accoding to a policy defined at compile-time (i.e. throw an exception, call abort(), do nothing, etc.) The main difference between the proposed raw_ptr and ::boost::any is that raw_ptr tries to follow the syntactic properties of void* as much as possible. A new cast type, namely raw_cast<T>(x) is proposed to replace static_cast, when casting from raw_ptr to typed pointer.

This deadlocks on Linux but not on Windows
by Clark Sims 11 Feb '08

11 Feb '08

I would like it to deadlock on windows, because I just wrote a large header file, which assumes that a deadlock will occur. In fact, I don't know how I am going to program mutex's and locks, if they act like recursive locks on windows, but scoped locks on linux. #include <boost/thread/thread.hpp> #include <iostream> using namespace std; void hello() { cerr << "this should deadlock" << endl; boost::mutex foo; boost::mutex::scoped_lock lock1(foo); boost::mutex::scoped_lock lock2(foo); cerr << "if you see this, then there was no deadlock" << endl; } int main(int argc, char* argv[]) { boost::thread thrd(&hello); thrd.join(); return 0; } --------------------------------- Never miss a thing.

[asio] read_until.cpp fails to compile on HP-UX_ia64_gcc
by Boris Gubenko 11 Feb '08

11 Feb '08

A couple of days ago (don't know exactly when), two asio library tests based on single source -- read_until.cpp -- started to fail to compile on HP-UX_ia64_gcc as the following: ../boost/asio/detail/socket_ops.hpp: In function 'int boost::asio::detail::socket_ops::select(int, fd_set*, fd_set*, fd_set*, timeval*, boost::system::error_code&)': ../boost/asio/detail/socket_ops.hpp:634: error: cannot convert 'fd_set*' to 'int*' for argument '2' to 'int select(size_t, int*, int*, int*, const timeval*)' While compilation error is obvious and can be eliminated by compiling with _XOPEN_SOURCE_EXTENDED macro defined, I could not figure out by looking at SVN log what changes have caused it. I verified that with _XOPEN_SOURCE_EXTENDED macro defined, all asio library tests pass on HP-UX_ia64_gcc. On another HP-UX/gcc platform participating in Boost testing -- HP-UX_pa_risc_gcc -- they pass with and without this macro defined. The platform details: HP-UX_ia64_gcc : HP-UX 11.23 ia64 with gcc 4.2.1 HP-UX_pa_risc_gcc : HP-UX 11.11 PA-RISC with gcc 3.4.2 Is it expected that asio library tests on HP-UX/gcc should be compiled with _XOPEN_SOURCE_EXTENDED macro defined? (for example, for SOLARIS, asio/test/Jamfile.v2 defines _XOPEN_SOURCE=500 and __EXTENSIONS__) And what was the change that broke HP-UX_ia64_gcc ? Thanks, Boris

Review - Logging Library
by Tom Brinkman 11 Feb '08

11 Feb '08

* What is your evaluation of the design? Introduces alot of new concepts for something relatively simple, logging. A study of the headers suggests a boostified functional style, but with lots of macros, which some developers here have no objection over. I on the other hand would like to see less, or even no macros in the public interface. A functional, lambda style logging interface should be adequate. If a macro is needed, suggest it as a work-around, but dont force it on the user in the example(s). * What is your evaluation of the implementation? No issues. Author appears to be knowlegable in the problem domain. * What is your evaluation of the documentation? Overall, I didnt like the informal style, but I was able to get the information I needed. Author tries to be too "cute" or "friendly". Author should get rid of informal comments and replace them with more professional language. An example of informal language is: "Yup, we have other examples as well. We also have a starter project." * What is your evaluation of the potential usefulness of the library? Potential is high. Would I use this library. As it stands, no. The tradeoff/benefits still suggest to me that logging requirements are too application specific, and this library doesnt change that equation. If it had a simple, boostified, lambda interface, with no macros, and no learning curve, I would probably use it. As it stands, its too complicated, with too little benefit for me to us it. Sorry. * Did you try to use the library? With what compiler? Did you have any problems? It compiled on GCC, linux, ubuntu, with some warnings, which I ignored. * How much effort did you put into your evaluation? Three hours * Are you knowledgeable about the problem domain? Yes. * Do you think the library should be accepted as a Boost library? No. I would evaluate it again, if the author would create a more boost friendly, lambda style public interface. Tom Brinkman
