Please let's avoid sending mails containing HTML parts
by Jens Seidel 01 May '08

01 May '08

Hi, I noticed that Boost's mailing list rules don't forbid sending useless HTML attachments which is not a good idea for discussion lists. Please let's extent http://www.boost.org/more/discussion_policy.htm to avoid this. Advantages: * Smaller messages * Faster opening (difference between text and HTML parts can be factor 10 and more!) * More consistent display formatting (no differences between text and HTML can occur without HTML) * There is absolutely no need to send HTML stuff. If one really depends on pictures or similar stuff the person should use normal attachments or even better upload the data to a remote site Omitting HTML parts is just a common rule for many lists, strange that Boost didn't enforce it yet.

Status of property_tree library
by Marcin Kalicinski 01 May '08

01 May '08

I'll try to shed some light on what has happened to property_tree since review and why it's been dragging. Since review I had some feedback about the library. The issue raised most frequently was unsatisfactory performance. Ptree does too many memory allocations, and thus is fairly slow and unsuitable for many users. Plus some of the original parsers (XML parser specifically) were really slow and took ages to compile, especially on gcc. Because this is headers only library that is supposed to be lightweight, this was a serious problem. To solve it I spent some months implementing a very fast in-situ XML parser for the library (called rapidxml - see rapidxml project on sourceforge). This was finished in August last year and integrated with property tree. It works very well and is so fast that time to parse XML is now totally insignificant compared to the time it takes to build a ptree from the parsed data. The allocations problem remains. I have been unable to come up with a scheme that would reduce the number of allocations without compromising simplicty of the library. The key point is that I want to maintain validity of iterators in presence of insertions/erases. This rules out array based containers. The best I can think of is a custom list implementation. That has potential to reduce number of allocations by roughly 30%, which is not enough IMO. On top of that I'm not sure whether the heavy type-parametrization of the library (i.e. lots of template parameters everywhere) is a good thing. It definitely makes it harder to document, use and understand. In all the the feedback I got there is no evidence of anyone actually using these template parameters. So IMO these should be reduced to just the character type. Otherwise the library pretends to be a generic tree container, which it wasn't supposed to be. Finally, probably the main reason the library is dragging is docs. The original docs (still available at http://kaalus.atspace.com/ptree/doc/index.html) were written in a gargantuan effort manually in HTML. This was a horrible experience that I do not wish to repeat. Some sort of automated docs generation is needed. I know about QuickBook and I like its wiki syntax. About a year ago I even managed to setup the toolchain correctly (including doxygen). The output of [code->doxygen->quickbook->boostbook->xml->xslt->html] pipe was not very satisfactory though, the reference entries were badly formatted and scattered all over the place in a disorganized fashion. I wouldn't like to give up the library because I still work on it occasionally. But as I wasn't able to solve major problems (docs tools, performance) satisfactorily, the work towards the release has ground to a halt. IMO the issues that should be addressed before release are: - Simplification by removing some of the template arguments (arguable - maybe someone is using that?) - Figure out which parsers are unneccessary and get rid of them (cmdline parser?) - Get some docs toolchain to work properly and provide up-to-date docs. Lots of the text can be ported over (and my monkey english corrected :-) from the original docs. - Speedup through use of a custom container (to replace std::list, needs some profiling work if it's even worth it) If someone could help with the docs toolchain (Quickbook experts? Any alternatives?) I'm happy to do the rest. I should probably give up on trying to speed it up further and concentrate on getting it into releasable state. thanks, Marcin

Review Requests: shifted_ptr, list, stack & roofof
by Phil Bouchard 01 May '08

01 May '08

Greetings Boost: I am happy re-submitting after 4 years my final design and implementation proposal of "shifted_ptr" which includes very useful tools named "list", "stack" and "roofof". The new containers consisting of STL-like ones but offering external access to the nodes, removing the need of dynamically allocated nodes and thus offers multi-dimensional control over their elements. "roofof" is a one line helper function used in conjunction with the mentionned containers to find the root address of the class housing the member used by the container in question. In contrast with its previous submission, "shifted_ptr" now relates to a memory manager of constant complexity and of size: sizeof(void *) * 2. It take advantage of the low-memory consuption, fast execution and very versatile interface. It proposes a very different concept, removes the need of current functions such as: "enable_shared_from_this", destroys the "cyclic pointer" problem and is now perfectly type-safe. The former reference counted smart pointer was renamed to "shifted_ptr_base" and merged properly with Boost standards. Morever "shiifted_ptr" is closely tied to the current "shared_ptr" that uses objects derived from "sp_counted_base". This was extended to objects deriving from "owned_base", which includes the necessary information that is handled by the smart pointer plus a smart destructer that differentiates arrays from standard objects and destroys the object accordingly. I have not yet written entirely its documentation but I have included a well documented reference to its API. I would like to schedule a review for now and by then the documentation shall be completed. I am also aware the library doesn't yet handle multi-threaded applications but I would like to start with getting the library better known. The theory behind is perfectly reliable but I can't say I forgot technical issues. The library is located at: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filenam… Thank you, Phil Bouchard

[exception] enable_exception_cloning.hpp should include <new>
by Boris Gubenko 29 Apr '08

29 Apr '08

boost/exception/enable_exception_cloning.hpp uses std::bad_alloc without #include'ing <new>. Because of this, some exception library tests fail to compile on HP-UX. Thanks, Boris

Summer of Code 2008 Ideas
by Mikael Olenfalk 26 Apr '08

26 Apr '08

Hi everybody! I saw that you are starting to think about SoC 08 and I have a couple of ideas: I cannot vouch for the usefulness of any of these proposals :) 1. Boost.Asio 1. add support for SCTP (Stream Control Transmission Protocol) besides TCP and UDP - more information on SCTP can be found on http://www.sctp.org/rfcs.html - I have not yet used SCTP anywhere so I cannot actually judge its importance, the *NIXes seem to support SCTP for some time now, I am unsure about Windows but it looks like Vista and Server 2008 do support SCTP - All *NIXes use the SCTP socket api - I do not know what the API on windows for SCTP looks like 1. add support for BEEP on top of TCP - BEEP is an "application protocol framework", basically it is just a set of guidelines packaged for application protocol design, which solves common problems one faces when designing new application protocols - http://beepcore.org/doc.html contains more information - http://beepcore.org/beep-toolkits.html lists current toolkits for BEEP 2. Boost.Serialization 1. add archive types for ASN.1 encoding rules, e.g. BER, DER, EDER, XER, etc. to be used together with Boost.Asio or perhaps even Boost.Asio.Beep (not that beep forces you to use any specific encoding) 2. Wikipedia has links and information: 1. http://en.wikipedia.org/wiki/Abstract_Syntax_Notation_One 2. http://en.wikipedia.org/wiki/Basic_Encoding_Rules 3. http://en.wikipedia.org/wiki/Canonical_Encoding_Rules 4. http://en.wikipedia.org/wiki/Distinguished_Encoding_Rules 5. http://en.wikipedia.org/wiki/XML_Encoding_Rules 6. http://en.wikipedia.org/wiki/Packed_Encoding_Rules 7. http://en.wikipedia.org/wiki/Generic_String_Encoding_Rules 3. Boost.Asn1 (for lack of better name) 1. Boost.Spirit-like DSEL for embedding ASN.1 notation directly in C++; then you could "easily" implement ASN.1 based protocols without the need for code generation outside of your C++ compiler 2. see http://en.wikipedia.org/wiki/Abstract_Syntax_Notation_Onefor more information on ASN.1 3. This might overlap with proposal 2 for Boost.Serialization 4. Finish Boost.Process (I think that it was a SoC 2007 or 2006 project) With kind regards, Mikael Olenfalk

Compiling Boost c++ library in Mementics in QNX
by Lakshmi Narasaiah 15 Apr '08

15 Apr '08

Hi, Actually we have to compile a program with Boost C++ in QNX(Gcc 2.95.3) using momentics. We have downloaded Boost C++ version 1.34.1. In QNX the Gcc version 2.95.3 is there along with QCC. First we have installed Boost C++ by following the commands. 1) ./configure --with-toolset = gcc, and 2) make install Some targets are skipped, some are not built and some more are built. In Momentics IDE(with GCC 2.95.3), we wrote one sample program with Boost C++, while compiling, it took much time and around 100 errors were there. These errors are from the Boost C++ library. We wrote a small program as follows <boost/filesystem.hpp> int main () { return 0; } We set the "extra include path" in the compiler option in momentics as /usr/local/include/boost-1_34_1 where we have the boost directory and in that we have the FileSystem.hpp file. Also in the boost directory we have the following directory filesystem which contains the convenience.hpp and operations.hpp. Kindly let us know if we are heading in the right direction. The errors and the console o/p are attached. Regards, Lakshmi. --------------------------------- Now you can chat without downloading messenger. Click here to know how.

[test] reporting problems from tests
by Maxim Yanchenko 14 Apr '08

14 Apr '08

Hi Gennadiy! I'm using Boost.Test 1.34.1. I have some questions: 1) Is it possible to customize the output? As I see in boost/test/impl/compiler_log_formatter.ipp: void compiler_log_formatter::print_prefix( std::ostream& output, const_string file, std::size_t line ) { output << file << '(' << line << "): "; } This is MSVC compiler output syntax, and integrates with MSVS only. But many other compilers (at least gcc, suncc) and unix tools like grep print their messages in the form "filename:line: ", and there are many tools/IDEs supporting exactly this format but not "filename(line): ". Is it possible to customize it? Maybe by using Boost.Format, or any kind of config #define, or anything else. 2) timeout. You working with timeout using SIGALRM, but this interferes affects sleep(), alarm() etc. You can read about it here: http://www.opengroup.org/onlinepubs/000095399/functions/sleep.html To me, it looks dangerous as there are many applications calling sleep(). What do you think? 3) --catch_system_errors Is it possible to set it to false by default? Everybody wants to have a core dump if the program crashed, the only scenario when cores are unwelcome - huge test suits with many-many binaries, when crashing tests can just exhaust disk space. But such huge test suits will be run from scripts where the number of parameters doesn't matter. But when I run a single test manually - I (and everybody I know) expect it to crash, to have a possibility to dive into the core with the debugger. You know the errors leading to crashes are usually very hard to reproduce, so it's quite frustrating when you lose a chance to understand an error just because you forgot to type this "--catch_system_errors=no" or forgot to setup environment variable. I just faced this problem. The test crashed but no core was dumped. Immediate rerun gave no crash. So I just ran the test in cycle and only after two(!) hours it finally crashed. That's why I'm voting for setting crash the default option. For now I just went to the boost sources and changed the code to make "no" default option. But I'm looking for more elegant solution. For example, why not to place all default values to config defines like BOOST_TEST_DEFAULT_SOMETHING? 4) I finally found the problem in the crashing test - it crashed inside Boost.Test due to parallel calls to Boost.Test checks. Any plans to do anything with this? 5) Printing objects in failed tests For example, what if I have BOOST_CHECK_EQUAL(a,b) and there is no operator<< defined in the classes? Or they're defined, but do something that I don't want to see in this particular test output (because it dumps the object in binary form, for example)? Is it possible to customize this somehow, e.g. by passing a printing functor as a third parameter, or any other way? Bests, Maxim

[review][proto]suggest doc debug & category guided design
by Larry Evans 09 Apr '08

09 Apr '08

It's all in the attachment. I had several other topics I wanted to explore; however, this will have to do for now. NOTE: The following is based on a download on 2007-02-17 of proto.zip from boost vault. * What is your evaluation of the design? Fair. One problem is the "mixing" of grammars with transforms. As stated here: <boost-root>/libs/proto/doc/html/boost_proto/users_guide/expression_transformation/canned_transforms/pass_through.html all expression generator meta-functions (For example, posit<>, shift_right<>, function<>, nary_expr<>, etc.) have a pass-through transform by default. which means that when, for example, matches<posit<_>,Expr> is compiled, the associated pass-through transform is not used. If it's not used in matches, then it should be eliminated. Of course it is used when the transform is applied; however, a transform template class taking a grammar as argument (the proto::when template seems appropriate) should be used to do that. This would make it clearer what the programmer's intention is. That means another template instantiation, thus slowing compile times; however, I think the time saved in understanding the code would compensate for that. Of course that's a judgment call. This "unused transform" feature is especially obvious with and_. Only the last transform (call it Xn) associated with the list of and_ args can ever be used. If transforms were eliminated from the and_ args and and_ was only used for matches, then: when<and_<G1,...,Gn>,Xn> could be used with the same effect as and_ with transforms associated with the args. Here, when is more obviously a transform, Tn,enabled by condition and_<G1,...,Gn>. Hm..., but that "looks" (based on what if means in c++) more like proto::if_, however I've never used proto::if_ and haven't read proto::if_ docs; hence, maybe that conclusion is all wrong. I have read somewhere that proto::if_'s 1st argument is a transform, which seems odd when the if_ name would suggest it's a grammar with a noop (unused) transform. What about proto::or_<T0,T1,...,Tn>? If the T0,T1,...,Tn were changed to "pure" grammars, G0,G1,...,Gn, then how would the *very* useful examples of transforms such as CalcArity in: <boost-root>/libs/proto/doc/html/boost_proto/users_guide/expression_transformation/example__calculator_arity_transform.html be done? Well, as explained in the in-source comments to proto::switch_ in matches.hpp, proto::switch_<Cases> could be used instead. OOPS, looking at switch_ shows it contains: template<typename This, typename Expr, typename State, typename Visitor> struct result<This(Expr, State, Visitor)> { typedef typename Cases::template case_<typename Expr::proto_tag> which; typedef typename which::template result<void(Expr, State, Visitor)>::type type; }; and, along with the example in code in /libs/proto/test/matches.cpp, shows that the only test is on the tag of the grammar and not the children. So.. maybe switch_ should be renamed to switch_tag and a new template, switch_gram, which does what the current or_ does except the template argument's are instances of a new template, proto::case_, where proto::case_ is like the current proto::when except: 1) The first arguments don't have to have a transform associated with them. 2) There's a default 2nd argument to proto::case_ which is identity_t (identity transform, which is the same as the transform part of the current proto::terminal): struct identity_t { template<typename Sig> struct result; template<typename This, typename Expr, typename State, typename Visitor> struct result<This(Expr, State, Visitor)> { typedef Expr type; }; template<typename Expr, typename State, typename Visitor> Expr const &operator ()(Expr const &expr, State const &, Visitor &) const { return expr; } } So, with these additional templates, the CalcArity might be: struct CalcArity : switch_gram< case_< terminal_g< placeholder1 >, mpl::int_<1>() > , case_< terminal_g< placeholder2 >, mpl::int_<2>() > , case_< terminal_g<_>, mpl::int_<0>() > , case_< unary_expr_g<_, CalcArity>, CalcArity(_arg) > , case_< binary_expr_g<_, CalcArity, CalcArity>, mpl::max<CalcArity(_left), CalcArity(_right)>() > > {}; where: XXX_g, for XXX={terminal,unary_expr,binary_expr}, is the "grammar part" of the current XXX template. However, even here there's a sortof mixture of grammar and transform. The "source" grammar of the transform is the one that appeared earlier on the example__calculator_arity_transform.html page (here, renamed CalcGram and with XXX->XXX_g [see where: paragraph under CalcArity above]): struct CalcGram : or_< terminal_g< placeholder1 > , terminal_g< placeholder2 > , terminal_g< _ > , unary_expr_g< _, CalcGram > , binary_expr_g< _, CalcGram, CalcGram > > {}; In order to completely separate the grammar from the transforms, something like an algebraic homomorphism: http://planetmath.org/encyclopedia/HomomorphismBetweenAlgebraicSystems.html is needed. Each function name, w_A, in source algebra in that reference would correspond to some grammar, G_w, in the or_: or_<G1,G2,...,Gn> The bad thing about that is that the function names would be sorta a duplication of the grammars, I think (I haven't thought it thru really). The only way I can be more certain of this is to try and implement it; however, I'm already way late in doing this review, so, that suggestion about complete separation of grammar from transform is just *highly* speculative. * What is your evaluation of the implementation? Not done. * What is your evaluation of the documentation? Good. However: 1) Some transform template's are barely documented or not documented (except in-source) at all (e.g. switch_). There really needs a full toc like the mpl one here: http://www.boost.org/libs/mpl/doc/refmanual/refmanual_toc.html I almost always go there when I want to figure out what mpl templates do. 2) Some transform documents are verify formally documented. IOW, they have almost a set of rules for guiding the reader, step-by-step, into how the transforms work. Each step in the process is described by a table in documentation of the outermost template. These tables have the before expression in the 1st column and the step's resulting expression in the 2nd column. This is very good. I used it to help me understand parts of proto. However, manual execution of rules on a given expression is hard because the user has to keep track in his mind the intermediates steps, and that's a lot of mental bookkeeping. It would be very helpful if there was a "proto-debugger" which, given an source expression, executes each of these steps (noting which table is being executed) and shows the correspondence between names in the "rules tables" with names in the source expression or intermediate expression, and finally stops when the expression cannot be reduced further. Maybe even proto could be used to do this. A sorta "self-aware" proto ;) This ability to take an expression and simply it using a set of rules would have uses in other domains, as shown by Task 3 in Markus' post: http://lists.boost.org/Archives/boost/2008/03/134376.php There's a prototype of doing something similar (although no association is shown between rules and tables) for language grammar analysis in the vault: http://www.boost-consulting.com/vault/index.php?&directory=Strings%20-%20Te… It just uses proto::eval to go through the steps until not further change is possible. 2) There needs to be a more detailed description of how the 1st argument, the expression argument, of proto::matches "relates" to the 2nd argument, the grammar argument. The description here: <boost-root>/libs/proto/doc/html/boost/proto/result_of/matches.html only uses "expression grammars" but makes no mention of proto meta-functions for generating expressions: <boost-root>/libs/proto/doc/html/boost_proto/users_guide /expression_construction/tags_and_meta_functions.html Judging from the example of using a terminal grammar, terminal<X>, to generate an expression by appending ::type: terminal<X>::type I jumped to the rash conclusion that a similar technique would work for binary_expr<Tag,L,R>. IOW, an expression could be generated by: binary_expr<Tag,L,R>::type However, this is only true if L and R are already expression. This rash conclusion lead to a time consuming "debugging of my thinking" as evidenced by the thread: http://lists.boost.org/Archives/boost/2008/03/133715.php Instead, the ::type appending must be propagated to all sub grammar expressions, as done by the morphism template attached to: http://lists.boost.org/Archives/boost/2008/03/134964.php Avoiding the rash conclusion mentioned above would probably be easier if proto grammars were prominently classified on some page into the following grammar subtypes: 1) expression grammars: These are the grammars appearing in the matches.html page mentioned above. These also are expression types; hence, the can also be used as the first argument to matches. In contrast to the meta-function grammars [2) below], for any expression grammar, E, the following expression fails to compile: E::type (Digression to design review: This "schizophrenic" feature of expression grammars makes understanding match harder in a similar way that untyped variables in an interpreted language makes understanding that code's functions harder. If there were an as_gram<ExprType> meta-function which returned the corresponding meta-function grammar generator, and only meta-function and predicate grammars [see below] were allowed as the 2nd argument to matches, then this would ease understanding and probably debugging [since, hopefully, deciphering compiler error messages would be easier]. Alternately, there could be an is_gram<ExprType> that when used in some kinda debug mode, diagnosed, with clearer error messages than the compilers, that ExprType was not a valid grammar. This is_gram could implemented using the boost concept checking library, AFAICT. ) 2) meta-function grammar: These (except for the nullary ones) appear in the last column of the table on: <boost-root>/libs/proto/doc/html/boost_proto/users_guide /expression_construction/tags_and_meta_functions.html As the name, meta-function, implies, they all have a nested ::type which returns the corresponding expression type [a.k.a. expression grammar, see 1) immediately above]. These are classified as nullary and non-nullary depending on the number of "sub-grammars": nullary) These are the ones formed by the proto::op::terminal template. They have no sub-grammars. non-nullary) These have an associated number (the arity) defining the number of sub-grammars. Each non-nullary template also is associated with its own c++ operator. The arity of the grammars is the same as the arity of the associated c++ operator. definition: meta-function grammar instance: basis-step) A nullary meta-function grammar is an meta-function grammar instance. induction-step) If O is a non-nullary meta-function grammar template with arity, N, and O1_inst,O2_inst, ... ,ON_inst are all meta-function grammar instances, then O<O1_inst,O2_inst, ... ,ON_inst> is an meta-function grammar instance. 3) predicate grammar: These are grammars with no corresponding c++ operators. In contrast to meta-function grammars, for any predicate grammar, B, the following expressions fail to compile: B::type tag_of<B>::type One reason for this is because there maybe be more than one type of proto expression that matches a given predicate grammar. For example, either an expression matching T0 or one matching T1 matches or_<T0,T1>. There one special case of a predicate grammar, the wild-card predicate: proto::wildcardns_::_ which matches any proto expression. This is analogous to a Boolean predicate always returning true no matter what the argument. Other important predicate grammars (in proto::control namespace) are not_, and_ and or_. AFAICT, just like any predicate logic expression can be constructed using: true not and or the equivalent of all other predicate grammars, such as: if_ can be constructed using just these four: _ not_ and_ or_ * What is your evaluation of the potential usefulness of the library? Very. * Did you try to use the library? With what compiler? Did you have any problems? Yes: http://www.boost-consulting.com/vault/index.php?&directory=Strings%20-%20Te… &filename=cfg_lookahead_extends.zip &filename=toy_attract.pair.zip * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? In-depth, although till have a long way to go. * Are you knowledgeable about the problem domain? Somewhat; however, I'm obviously unfamiliar with the specific problems proto was designed to solve. For example, I was unaware of some of proto viewpoints expressed by Eric in the last 2 paragraphs of this post: http://lists.boost.org/Archives/boost/2008/03/134959.php * 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. Eventually, but not yet. There needs to be more documentation debugging and also more exploration of alternative designs, in particular, designs guided by algebraic morphisms and category theory. One justification for this exploration is the morphism template in attachment to: http://lists.boost.org/Archives/boost/2008/03/134964.php Although that post observed that that morphism template: is correct in the limited case of those dual-purpose grammars-and-metafunctions. that doesn't mean it couldn't be extended to handle more general cases. In particular, in the case of expression grammars, I'd think the morphism template in the attachment could just be specialized to be an identity morphism: template < class Tag , class Args , int Arity > struct morphism < expr<Tag,Args,Arity> > { typedef expr<Tag,Args,Arity> type; }; Further specialization designed to error when given a predicate grammar would, AFAICT, correctly calculate from either a meta-function grammar or an expression grammar the matching expression type. Category theory *might* be used to guide the predicate grammar design, as suggested (very indirectly) by parts of: http://www.amazon.com/Algebraic-Approaches-Semantics-Monographs-Computer/dp… For Section 3.3, "The Boolean Algebra of Guards", contains: Pascal allows a statement of the form: if x>0 and not x=5 then S_1 else S_2 If S_1,S_2 are to be semantically interpreted as morphisms X->Y in a category _C_, how can "P and not Q" be interpreted, where P is "x>0" and Q is "x=5"? ... Equivalently, they [i.s. P and Q] may be represented as guard functions as in 1.5.20. ... for an object X in a partially additive category _C_, there is a subset, Guard(X) of _C_(X,X) of "guard morphisms" which form a Boolean algebra. On the same page where 1.5.20 mentioned in the above quote appears, there's: 22 Definition. let (p1,...,pn) be an n-way test on X and let f1,...,fn be in SC(X,Y). Then a natural generalization of the case statement in Pascal is: case(p1,...,pn)of(f1,...,fn)=f1 p1+...+fn pn where the p's correspond to the lhs of the when's in an or_ with elements decorated with transforms and the f's correspond to the transforms on rhs of the corresponding when's. In conclusion, the somewhat vague similarities, noted above, of proto with algebraic morphisms and, more generally, with category theory strongly suggests (to me at least) there could be a large benefit to trying to make these similarities more concrete and using that knowledge to improve proto's design.

async_read_until and \0
by Billy Chasen 06 Apr '08

06 Apr '08

Hello, I'm creating a server using boost:asio and am receiving data that ends with a \0 char (from flash sockets if you're curious) async_read_until seems to not like this as the delimiter. (If I switch to a diff delim like \r\n it works fine) How can I get async_read_until to work properly? thanks, billy
