[proto] minor issue: unnecessary typedefs _arg*
by Markus Werle 18 Mar '08

18 Mar '08

Hi! This is a minor issue, but nevertheless I'd like to share my opinion on this: The longer I think about _arg0 and its brothers and sisters the more I get the impression that they should be banned from proto. 1. Especially the typedefs for _arg, _left and _right should be removed from the library, because they duplicate the interface and bring more confusion than convenience. While rereading through the docs I tried to replace those typedefs with their arg_c<> substitutes before my inner eyes - et voila, the approach to the design is much easier now. I think _left and _right are in for historic reason (you always start thinking about ET as binary trees, e.g. while reading Veldhuizen's paper), but one thing should have one name in a general purpose library. Also it is a very good approach to proto, to repeat 100 times every morning that any operator is nothing but an oddly written function call. For function calls it makes no sense to talk about left and right. So a minor argument is didactic clarity. The major argument is: No fat interface here! This is not std::string, this is boost::prior(std::etl). Summary: I strongly vote against _arg, _left and _right. 2. From a user's point of view I still cannot see the advantage of using argSOME_NUMBER instead of arg_c<SOME_NUMBER>. Couldn't you make arg_c<XX> a first class citizen of namespace proto? So even if it makes it easier to write the boilerplate parts of proto itself, names based on MACROS are still evil enough to remove them from the _interface_ and for me _argSOME_NUMBER is part of the interface. IMHO templates with integer arguments scale well enough not to introduce PP garbage here. I have the suspicion that _argSOME_NUMBER is only inside because you have all those BOOST_PP_MAKE_MY_CODE_WRITE_ONCE_NEVER_UNDERSTAND_LATER. Note that this is not a show stopper for me, I propose the ban, but in contrast to _arg, _left and _right I can live with those, since transform::arg_c<I> is at hand and I will use those right from the beginning and ban _arg0 from my own code consequently. <kidding>Eric, you will only have to pay for all those extra "transform::" I have to type all the time. Let's say $0.02 for every occurence ... OK?</kidding> Eric, please classify right from the beginning, whether issue #2 takes on "bike shed characteristics" and/or disclose your rationale for _argSOME_NUMBER. Markus

Hi, I'd like to submit an application that has been proudly using Boost since v1.33: Application: Remobo Company: AWIT Systems, Inc. URL: http://www.remobo.com Remobo creates an Instant Private Network (IPN) between your computers and your friends. It's a COMPUTER Network based on your Social Network. With IPN service, you and your friends can work or play together over Internet as if you were sitting on the same office or home LAN (Local Area Network). Boost Libraries used: Asio, Bind, DateTime, File System, Function, Lexical Cast, Non-Copyable, Ref, Regex, Serialization, Smart Pointer, StateChart, Threads, Tokenizer, Tribool, Tuples, Utility, Variant We have been using boost for fault-tolerant, large-scale distributed systems with complex multi-threaded networking protocols. Boost Libraries has been a reliable & indispensable part of this cross-platform systems for the past years. We at the Remobo development team would like to thank everyone in the Boost community for their hard work that creates this high-quality project. Cheers, --- Jeffrey

Hi, there is a serious bug in the circular_buffer library (http://svn.boost.org/trac/boost/ticket/1692) which makes it unusable in the release mode (there are several more methods affected not only erase() as described in the ticket).

Support Requests in Trac

As we get close to the 1.35 release, I'd appreciate it if the people with open "Support Requests" in Trac (or anyone who wants to help out!) take a look at them and resolve them - or set a milestone for them to be resolved.

[TR1] Hash test failures on VC9

A couple of the TR1/Hash tests (http://tinyurl.com/3bjkrv, http://tinyurl.com/3cud5g) are failing on VC9 due to a bug in the MS libraries (see http://tinyurl.com/2vekxc for details). Do those tests need to be marked as expected failures? Thanks, Richard Webb

[1.35] Serialization shared_ptr_132 headers cause compilation error with g++ 4.1.0
by Clif Houck 18 Mar '08

18 Mar '08

Hi, I'm trying to update a code base to use boost 1.35 from boost 1.32. From what I've gathered, 1.35's code is frozen and considered to be fairly stable, so I figured that I wouldn't run into any errors caused by boost, just general changes that occurred between 1.32 and 1.35. Instead, it looks like I've definitely run into a bug being caused by 1.35, in particular, the serialization headers for shared_ptr. The following code: #include <boost/serialization/shared_ptr_132.hpp> #include <boost/serialization/shared_ptr.hpp> int main() { return 0; } Causes the following errors: g++ what.cc -o what -I /usr/local/include/boost-1_35/ -lboost_serialization-gcc41-mt-1_35 /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp: In function ‘void boost::serialization::load(Archive&, boost::shared_ptr<U>&, unsigned int)’: /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: ‘null_deleter’ is not a member of ‘boost::archive::detail’ /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: ‘null_deleter’ is not a member of ‘boost::archive::detail’ /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: template argument 2 is invalid /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: expected `>' before ‘*’ token /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: expected `(' before ‘*’ token /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:124: error: expected primary-expression before ‘>’ token Looking at the documentation included with 1.35 says to retain backwards-compatibility for 1.32's shared_ptr by including both headers in the order I have included them, so I'm at a complete loss. I must retain compatibility with shared_ptr from 1.32 since there is a lot of serialized data floating around from 1.32, and its not feasible to find all of it and convert it mechanically. I hope someone can lend a helping hand. Thanks, Clif Houck

[1.35.0] Links to version history?
by Beman Dawes 18 Mar '08

18 Mar '08

The version history for 1.35.0 is currently located at http://beta.boost.org/users/history/2008-01-23-version_1_35_0. Presumably that will translate to http://www.boost.org/users/history/2008-01-23-version_1_35_0. Why is the date part of the version name? That creates a problem for links from the release, since they have to be changed if the date changes? Would it be possible to change the location to plain http://www.boost.org/users/history/version_1_35_0? Presumably the same pattern should be followed for subsequent releases. Thanks, --Beman

[threads|interprocess] thread_locking_policy and process_locking_policy
by vicente.botet 18 Mar '08

18 Mar '08

Hello, I'm defining a class Locally Unique Identifier (see http://lists.boost.org/Archives/boost/2008/03/134088.php) that has a locking policy. This locking policy needs to define a mutex_type and a scoped_lock types. This could be null_locking_policy for monothreaded usage, thread_locking_policy for multi-threaded access and process_locking_policy for multi-process access. The problem is that when I try to initialize the scoped lock with a try_to_lock the types and variables are differents, even if both mùean the same. And so I need to add a function try_to_lock in the policy. struct thread_locking_policy { typedef boost::mutex mutex_type; typedef boost::mutex::scoped_lock scoped_lock; static const boost::try_to_lock_t try_to_lock() {return boost::try_to_lock;} }; struct process_locking_policy { typedef boost::interprocess::interprocess_mutex mutex_type; typedef boost::interprocess::scoped_lock<mutex_type> scoped_lock; static boost::interprocess::detail::try_to_lock_type try_to_lock() { return boost::interprocess::try_to_lock; } }; IMO we need to armonize the threads and interprocess synchronization interfaces. I don't know where these types and variables could be, but we need that both libraries use the same type and variable. Anyway, these trivial classes will be redone by each user defining a class that manage the synchronization in a wide context. Is there an interest in these locking policies classes. We can add recursive_thread_locking_policy and recursive_process_locking_policy . Where these classes could be placed. Why not in an new boost/sync directory? Please, let me know if there is a better solution already present on boost. Regards _____________________ Vicente Juan Botet Escriba
