Doug, - try us. I hereby grant you permission to use XEP to format Boost project's documentation in server environment until our VP of Sales - Kevin Brown, contacts Boost and emails our formal license for such purpose. Kevin should do it either tonight or in several days (he's out of town). He will also send you a license for DevKit that includes API. I think you will find it useful. Let me know if you need anything else: Java PDF, Docbook PDF related tools: www.renderx.com/tools our new development - DiType: http://moin.renderx.com/rxwiki We always like to work with technology people who promote open standards.

[Probability] version 0.2.3 released
by Brook Milligan 20 Aug '07

20 Aug '07

In order to better motivate the need for the Boost Probability library, I have updated the documentation, which is accessible at http://biology.nmsu.edu/software/probability/ Although this constitutes a new release, the only difference is in documentation. As a result, the contents of v0.2.2 in the Boost Vault still reflect exactly the most recent release and I haven't uploaded a new copy. The new motivational example is taken from the problem of ascertaining the long-term trend of global climate. One database used to assess this is available from the NOAA National Climate Data Center (http://www.ncdc.noaa.gov/oa/climate/ghcn-monthly/index.php) It contains monthly data for thousands of stations worldwide, in many cases for decades. Today's version, for example, contains 590,543 records of mean temperature. A typical likelihood calculation evaluating a model of climate would involve a product of likelihoods across all of these records, almost certainly yielding a result on the order of 10^{-600,000} or less. Such numbers cannot be handled using typical floating point representations, so specialized solutions of some form are required. The natural method is to accumulate the sum of logarithms of likelihoods, rather than the product of likelihoods, across the dataset. This keeps the values within suitable bounds, but requires keeping track of the fact that different types of values (probabilities, likelihoods, and log likelihoods) are being used throughout a typical program. If these are all represented using native types, such as double, it is easy to lose track of the fact that they have different semantics. A real solution of this problem would include modules taking care of calculating the probability of each individual data record and modules taking care of accumulating that information across the records. The problem is complex enough that each of these responsibilities would realistically be divided across many units and it would not be unreasonable to expect development to be divided among many programmers. In such situations it is all too easy to lose track of what semantics apply to a specific value when the only information available in the code is the data type (e.g., double) which provides little help and some (perhaps untrustworthy) comments that may or may not be read and in any case cannot affect the compiler. Using the Probability library, one can encode the exact semantics using the type system in a way that lends itself to generic programming. The resulting clarity, safety, and maintainability is retained regardless of how large the code base becomes and how the operations are distributed across modules and/or programmers. As a result of these features, I feel that this library makes a significant contribution to solving a well-defined set of problems that occur in certain types of scientific programming and modeling. I hope you will take a serious look at its capabilities and provide me with further feedback. I am especially interested in improving the portability of the code and need testers with access to compilers other than g++. I look forward to your comments, suggestions, and general discussion. Thank you. Cheers, Brook

SVN commit emails per-project
by Vladimir Prus 20 Aug '07

20 Aug '07

Is there any way to have per-project SVN commit emails? Say, I'd like all commits in tools/jam and tools/build/v2 to go to a dedicated mailing list. We used to have boost-build(a)lists.sourceforge.net mailing list for that, but not it obviously does not work. Thanks, Volodya

[Important] Boost Subversion repository is now online
by Douglas Gregor 20 Aug '07

20 Aug '07

Hello all, The Boost Subversion repository is now back online. All of the files in CVS (including their histories) have been imported into the Subversion repository. CVS is still available for anonymous, read- only access for now, but will not be updated. The main Boost development branch is available via anonymous, read- only checkout at: http://svn.boost.org/svn/boost/trunk/ Or for developer read/write access at: https://svn.boost.org/svn/boost/trunk/ Information about accessing the Boost Subversion repository is available at: http://svn.boost.org/trac/boost/wiki/BoostSubversion Please report any problems to me to the main Boost list, and we will try to resolve them as quickly as possible. We still need help porting the regression-testing script over to use Subversion. See Trac ticket #1122: http://svn.boost.org/trac/boost/ticket/1122 Also, there is more documentation that will need to be updated within the Boost tree. - Doug Subversion tip: when you commit a change to Subversion that fixes ticket number NNN, include the text "Fixes #NNN" in your commit log. Trac will automatically close the ticket and cross-reference the commit with the ticket. See, for example, http://svn.boost.org/trac/ boost/changeset/38330

Re: [boost] ScopeExit Review Begins Today
by Küppers, Ben 20 Aug '07

20 Aug '07

Alexander, I understand your gripes about the lambda syntax, but to be perfectly frank, I have never used lambda expressions in combination with the scope guard (which is maybe why your arguments have so far been unable to convince me). My clean up actions tend to be trivial function calls or functors that don't require any lambda syntax. Moreover, I am convinced any lambda expression wouldn't get through our code inspection for exactly the reasons you bring up. However, I fear that I will face similar resistance to your syntax. It's hard to argue that a macro with (seemingly) un-typed arguments, a code block between curly braces followed by another macro, look anything like C++ (and arguing its correctness based on a future language standard probably won't do me much good either). I think the scope guard functionality is an essential tool for many programmers so its syntax needs to be accessible to the masses. A quick glimpse through some of the other reviews seems to indicate that I am not the only one with this concern. -Ben This e-mail and any attachment is for authorised use by the intended recipient(s) only.

I was just curious what servers you had tested on. No need to apologise. Personally I would rather you implement the protocols then spend time testing against servers! ;) At the end of the day the end users (ie those interested in using the library) will test and provide feedback on how well it works. The main reason I was asking about support for IIS7, was it will be easier for me to test against this configuration (I am planning on setting up a virtual machine running server 2008 (I got a beta 3 disk at TechEd)). > > 2.

The main reason for this would be for portability; Note: I am making the assumption that the support for pipes would be *nix only. Peter.

Logically they are implementing different standards. I know there is some overlap in behaviour and use. Maybe this could be in a boost::cgi::common namespace and be pulled into each of the distinct namespaces. Peter.

Looking for ScopeExit Reviews
by Jody Hagins 19 Aug '07

19 Aug '07

The review ends in three days (on Wednesday). The current collection of reviews is very small, thus I am asking for more reviews of this library. Thanks! >From the original announcement... The review period for Scope Exit Time Series, submitted by Alexander Nasonov, runs from Monday, August 13 until Wednesday, August 22. >From the documentation: Nowadays, every C++ developer is familiar with RAII technique. It binds resource acquisition and release to initialization and destruction of a variable that holds the resource. But there are times when writing a special class for such variable is not worth the effort. This is when ScopeExit macro comes into play. You put resource acquisition directly in your code and next to it you write a code that releases the resource. Note that ScopeExit uses PP macros and relies on Boost.Typeof. The latest version can is here: http://boost-consulting.com/vault/index.php?action=downloadfile&filename=sc… It's available also at http://tinyurl.com/2z6qg2 Online documentation is here: http://194.6.223.221/~nasonov/scope_exit-0.04/libs/scope_exit/doc/html/inde… >From the review guidelines here: http://boost.org/more/formal_review_process.htm ... Boost mailing list members are encouraged to submit Formal Review comments: * Publicly on the mailing list. * Privately to the Review Manager. Private comments to a library submitter may be helpful to her or him, but won't help the Review Manager reach a decision, so the other forms are preferred. 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. Thanks in advance to every for your participation in this review.

Calling library maintainers
by Marshall Clow 19 Aug '07

19 Aug '07

I was doing some cleanup on the boost Trac this morning - trying to make sure that bugs were getting to the right people, and I have bugs that I want to assign to libraries (and maintainers), but the maintainers are not users on the Trac system. I would appreciate it if all library maintainers would create accounts for themselves on Trac. Instructions can be found here: <http://svn.boost.org/trac/boost/>. Doing bug triage this morning, I was looking for user names for: Ion Gaztanaga (interprocess) Thorsten Ottosen (range, ptr_container) Stephen Cleary (pool) Jaakko Jarvi (lambda) Fernando Cacciola (optional) Alexander Nasonov (any) John R. Bandela (tokenizer) If I've got any of these names wrong or if someone else is now maintaining these libraries, please let me know (they came from "libs/maintainers.txt") Thanks in advance! -- -- Marshall Marshall Clow Idio Software <mailto:marshall@idio.com> It is by caffeine alone I set my mind in motion. It is by the beans of Java that thoughts acquire speed, the hands acquire shaking, the shaking becomes a warning. It is by caffeine alone I set my mind in motion.

[Intrusive] More compile time parameters
by Rei Thiessen 18 Aug '07

18 Aug '07

Hello, (my version of the library is intrusive.2007-03-04.zip. Is there a more recent version?) I have three suggestions: 1) The containers uses a modulo operation to map the hash value range into the bucket index domain. When using a bucket size that is an order of 2, the excess cost of the div instruction is unneeded. This was a critical issue for me. There can be a new templated type parameter for specifying a functor that takes the hash output value and the bucket size as inputs and outputs the bucket index. The default type of this template parameter can simply be std::modulus. 2) Each container stores the bucket size. This is too an unneeded excess in certain circumstances. If the containers had a (optional) templated constant parameter that determined its bucket size, then the container memory footprint can be reduced at the expense of bloating the code segments with multiple instantiations. This memory saving is crucial when deploying numerous small hash container objects. This new templated constant parameter has interface ramifications. We would require two specializations of the container class: the run-time bucket size specialization is what we have today; for the compile-time bucket size container, the constructors would not have "size_type buckets_len" parameters. 3) Now, if we add another templated type parameter for specifying a functor that takes the object 'this' pointer as input and outputs the memory address of the bucket array, then we can reduce the memory cost of each container to zero. Combining 2) and 3), we can develop a single concept: As an example... struct default_bucket_info { /* appropriate constructors... */ bucket_ptr buckets_; size_type buckets_len_; template<class T> bucket_ptr buckets( T* container ) const { return buckets_; } size_type buckets_len() const { return buckets_len_; } } Realizing 2): template< unsigned n > struct bucket_info_size_n { /* appropriate constructors... */ bucket_ptr buckets_; template<class T> bucket_ptr buckets( T* container ) const { return buckets_; } size_type buckets_len() const { return 1<<n; } } Realizing 2) and 3): template< unsigned n > struct bucket_info_in_place_size_n { template<class T> bucket_ptr buckets( T* container ) const { return (bucket_ptr)container; } size_type buckets_len() const { return 1<<n; } } Applying these concepts, I think we can reach a balance between having a concrete container class and having a collection of free container algorithm functions. (If only C++ would adopt C99's VLAs, 3) can be far more elegant...) Are there any drawbacks to extending the unordered associative container classes with these concepts? (I will be modifying my copy of the library with these changes for my personal needs) RT

Time Series review results
by John Phillips 17 Aug '07

17 Aug '07

I am pleased to announce that the Time Series library, submitted by Eric Neibler and developed by him along with Daniel Egloff, Matthias Troyer, David Abrahams and Daniel Wallin using funding provided by Zurcher Kantonalbank has been accepted into boost. As seen in the review, there are some important issues that need to be addressed before the library is ready for boost distribution, however I am confident that this is a very good library. Although the donation of time and funding for Time Series by Zurcher Kantonalbank is laudable and something we would like to encourage more companies to do, the fact that it was donated is not important to the review process. Something that is important is the well-established reputation of the involved lead developer. Eric has a number of very high quality libraries already in boost and has shown his willingness to support them thoroughly and improve them continually. He has been very responsive to user feedback and has an obvious desire to have only high quality work committed to boost with his name on it. For this reason, I am giving him a little more leeway than might be given to a developer without his reputation to address the issues in this review and enter the revised version into boost without a fast tracked second review. Many thanks to the participants in the review: Tom Brinkman, Hugo Duncan, Andrey Tcherepanov, Matthias Schabel, Steven Watanabe, Stjepan Rajko, Matias Capeletto, Matthias Schabel, Lewis Hyatt, Paul Bristow, Tobias Schwinger, Matthias Troyer, Phil Endecott, Zach Laine, Dave Abrahams, Michael Marcin, and Michael Fawcett for their time and attention. The discussions held in this review provided a strong foundation for improving the library, and the variety of domains of expertise represented by the participants shows how broad the desire for a library of this sort is. Most of the points raised in the review have been directly addressed by Eric and discussed until a solution that is acceptable to all involved parties was reached. Eric has acknowledged many as now either fixed in his version or on his To-Do list. However, for the sake of easy reference I will list the major points and my current understanding of what to do about them below. The order in which the points are presented should not be taken as a rating of importance: it is just the order I made notes about them as I reviewed the discussion. 1) Fix the floating-point offset issues – The answer to this may be a change in how they are implemented or a complete scrapping of the floating point offsets as an indexing type. In either case, it would be a good idea to provide a view facade for time series that applies a constant multiplicative factor (or possibly a more general function) to an offset. This may even be a sufficient answer to all the floating-point issues, but it is not yet clear to me (or to anyone else that I noticed in the review) what the best answer is. I expect there will be continued discussion on the developer list to clarify this issue. 2) Polish and include the rolling window average example sent to the list – This is a very good example of a very potent design idiom for this library, and one that would help a lot of people better understand the potential of the library. The use of the circular buffer to collect multiple points is necessary for many filters. It is such a good case that you should consider not only including it in the library, but also making a tutorial out of it that shows how new algorithms can be added to the library. Ideally, many algorithms that are specific to domains that the authors are not specialists in will be donated by users who develop and polish them for inclusion. A very clear tutorial will make this more likely. 3) If the rolling average is not developed as a tutorial example, some other filter should be – There is no way the library can include all the filters in use by programmers in all the various use domains, so the expectation is that writing your own filters will be common. The documentation needs to support this very well. 4) The documentation needs improvement in a number of ways – Reorganization to build from foundational ideas and uses to the more complex issues is important, as is the addition of overview, tutorial and rationale sections, as well as a substantial increase in the number of examples. The learning curve is currently too steep and that seems to be discouraging users who might find the library a very good fit. An important step along the way is to add good examples and good pictures in many places in the documentation. This general note is reinforced in some of the other comments. 5) Small toy examples for each of the algorithms would make the documentation of them far more clear 6) Since you maintain both libraries, it would be useful to add to the documentation for both the Time Series and the Accumulators libraries some notes on how a user should select between them for specific jobs. This came up in discussions before the review, so it is likely to be a problem for more future users. 7) Well chosen pictures can help the readers of this documentation immensely – Especially in your attempts to clarify the documentation of the discretization, the offset and sample values, good pictures will be invaluable. 8) Expand the focus of the documentation so it doesn't appear to a casual reader that this is purely for econometric/financial time series – The library has potential uses in a wide variety of fields, so it is important that potential future users can tell that from even a light skimming of the documentation. 9) The prenamed discretizations seem to cause more problems than they solve – Initial testing of the boost::units library to provide discretization units looks hopeful. If this stands up under testing, not only remove the current prenamed discretizations, but also document using boost::units. A good example could do for this. 10) It is only possible to assign across series with the same discretization type – This should be made more explicit in the documentation and also since a good example of trouble that would be caused by trying to assign series with different discretization types showed up during the review, it might be added to the rationale section so users can see why the choice is a good one. 11) The reasoning behind having unit series for types that have no obvious unit member should also appear in the rationale – In general, there were many good explanations for design choices that should appear in the rationale section. Many of these reasons are compelling but not obvious to a developer who has not tried writing a time series library. Thus they are ideal rationale entries. 12) Currently non-entries in a dense time series are recorded as zeros. This does not seem to be the best idea in all cases. In specific, in some time series, the difference between a value of zero an unknown is very important. Investigate the best choice for a non-entry. Zero gives simple arithmetic for multiplication (though not addition) that gives the unknown value placeholder when multiplied with anything. Some non-zero value would have to have special arithmetic rules, probably. A universal answer may not be feasible. If not, consider making the unknown value a parameter available for the user to set. 13) Consider a name change from delta_series to dirac_delta_series and a link in the documentation to what a Dirac delta function is. 14) Consider renaming the inverse_series to reciprocal_series or some other more illustrative name. 15) Consider reorganizing to expose the storage containers to outside developers – They are likely to be useful for a number of applications aside from time series and this would prevent others from needing to reinvent the wheel as often. 16) Since the usage of time series is spread across a variety of different problem domains, there will be terms that aren't familiar to many of the readers of the documentation. Consider including links to definitions and descriptions for many of the terms used. Paul's example of users who don't know what amortized constant complexity implies is unfortunately not extreme for what you should expect. 17) ordered_inserter is not a great name for the operation it performs - Determine a better name and change to that. Also consider moving to named parameters for the start, stop and value arguments to the ordered_inserter. After all this, the ordered_inserter is a lower level interface than most users want in most circumstances. Add another layer for doing appends on top of this interface, and include a push_back method where sensible for more stl-like syntax. 18) There is a confusion between the template parameter discretization and the constructor parameter discretization. Consider changing the name for the template parameter to something like Discretization_type. 19) Include in the documentation a clear description of what it means for two discretizations to be the same, and point out that the runtime check for this is an assertion, not an exception. Explain why in the rationale section, if nowhere else. 20) A number of reviewers found the concepts of discretization, offset and run to be hard to grasp from the documentation. Work to improve this. 21) The comparison operators for the time_series_facade currently are tied to the time_series_base class. This could be generalized to remove that dependency. If this is done, the documentation should no longer say that time_series_base is the base for all time_series classes, but instead that it provides a convenient base for implementing time_series classes. If this isn't done, the documentation should clearly state the need to inherit from time_series_base. 22) A large number of specific documentation edits were provided in posts by Steven, Paul and Zach. 23) Fix the documentation to clearly show what kind of iterator the series_stl_iterator is. 24) This is outside the scope of this review for a complete answer, but there are questions about the behavior of non-MSVC compilers that define the _MSC_VER macro to masquerade as MS compilers. Is there a way to know which (if any) share the behaviors of the actual MS compilers they pose as, and what is the best way to test for them in code. While the pursuit of this answer is not part of this library, using it is, so if a good answer is found it should become part of this library. 25) Provide versions of the fine_grain and coarse_grain functions that allow for the user to easily provide a sampling function - This is likely to be a very common use case for this library, so it should be well supported. An example in the documentation of how to do this is a good idea. 26) If the review of floating point offsets concludes that they should remain in the library, the dense series reference page should explicitly point out that floating point offsets are not usable with dense series. 27) What is the appropriate handling of zero width points. They are a part of the library in the delta_series, so having them is unavoidable. They should be on firm conceptual ground if possible. 28) Make the existence and use of the set_at function more obvious in the documentation – Reviewers didn't notice it and missed the functionality, so others will, as well. 29) Consider whether it is valuable to provide versions of the transform algorithm that take more than two series as arguments. I can't think of a good application off hand, but there may be some. However, the same reviewer who requested the feature said earlier in the review that he almost never works on more than one series at a time. 30) Provide an example of using a single pass data stream with a circular buffer based algorithm. 31) Consider a better name for the scaled_storage_tag. 32) Consider whether users need access to the metafunctions used to determine return types. If so, consider how they could be exposed in a user friendly way. Once again, my thanks to the reviewers and the developers for the work, time and attention put into this library and congratulations to Eric for the accepted work. John Phillips Review Manager

[graph] csr_graph_test.

Boost building with CMake
by Bill Hoffman 17 Aug '07

17 Aug '07

Hi, I noticed the "boost development process / scope" thread on your list. A CMake user posted a link to your discussion. There is significant interest in the CMake community to help boost transition to CMake. Several people on the CMake list have volunteered to help, and Kitware is willing to put about 2 man weeks of effort into the conversion. I think that CMake has all the features to do what you need at this point, but if any bugs or issues are discovered during the process, we can fix them and/or provide work-arounds for the issues. I realize you have not yet decided on moving to CMake, but I thought I would put out this offer so that you could consider "free" support as one of the benefits you will receive from the port to CMake. I can see this happening in two ways. One would be for a CMake developer to create initial cmake files for boost, and get the basics working. Then, the work would be turned over to the Boost community. The other way would be to have a boost developer create the build files with help and support from the CMake community. Either way works for me. Of course, no one will want to do anything unless there is a commitment to actually use CMake. I will stay on this list while you decide, and answer any questions about CMake that may come up. Thanks, and I look forward to working with the boost community in the future. -Bill

Possible bug with mpl::joint_view working on two mpl::maps
by Martin Apel 17 Aug '07

17 Aug '07

Hi all, I have two mpl maps like this: typedef map<pair<int_<1>, int_<42> >, pair<int_<2>, int_<43> >, pair<int_<3>, int_<44> > > Map1; typedef map<pair<int_<4>, int_<44> >, pair<int_<5>, int_<45> >, pair<int_<6>, int_<46> > > Map2; I try to join them using "joint_view" as follows: typedef joint_view<Map1, Map2>::type JointMap; which works fine. Then I do std::cout << at<JointMap, int_<2> >::type::value << "\n"; which gives the following compiler error: error: 'value' is not a member of 'boost::mpl::pair<mpl_::int_<3>, mpl_::int_<44> >' I tried this with gcc 3.4.6 and 4.2 under Linux, Boost version is 1.34.0. It seems "at" returns the entry after the searched entry, and not only the right half, but the complete pair. Has anybody got any hints on this? To me it looks like a bug in MPL, but I might be wrong. Best Regards, Martin ____________ Virus checked: AVKB 17.336 from 12.08.2007

[Announcement] Boost joins the Software Freedom Conservancy
by Beman Dawes 16 Aug '07

16 Aug '07

Effective August 10th, 2007, Boost became a member project of the Software Freedom Conservancy, http://conservancy.softwarefreedom.org. This means that Boost is now part of a legal entity under US law, and tax-exempt under section 501(c)(3) of the US tax regulations. Although this doesn't have much short-term effect, it lets us move forward with BoostCon 2008 planning with less administrative delay. Long-term, being part of a non-profit organization allows Boost to continue to grow and prosper, and to raise money if that becomes useful. After considering the option of starting our own foundation (a huge amount of work), the Boost moderators decided that joining the Software Freedom Conservancy was a better option. The SFC provides the same legal abilities of a foundation at NO cost to the Boost project. It also minimizes the amount of legal and administrative hassles for project members -- allowing us to stay focused on technical matters rather than tax law. In addition, we are free to leave the SFC and create our own foundation at a later time if we decide that the SFC is not serving us well. Boost is not alone -- some other well known open source projects have also joined the SFC (eg: Samba, Wine). For those interested in the details, see a copy of the legal agreement at svn.boost.org/svn/boost/trunk/more/BoostSponsorshipAgreement.pdf I signed for Boost, since I was the founder and am the owner of the boost.org domain name. Dave Abrahams gets the credit for working out the details of the SFC agreement, with the help of the other moderators. --Beman

ScopeExit Review Reminder
by Jody Hagins 16 Aug '07

16 Aug '07

We have received only a few reviews so far. The review ends in less than a week, so time is running short. Thanks! >From the original announcement... The review period for Scope Exit Time Series, submitted by Alexander Nasonov, runs from Monday, August 13 until Wednesday, August 22. >From the documentation: Nowadays, every C++ developer is familiar with RAII technique. It binds resource acquisition and release to initialization and destruction of a variable that holds the resource. But there are times when writing a special class for such variable is not worth the effort. This is when ScopeExit macro comes into play. You put resource acquisition directly in your code and next to it you write a code that releases the resource. Note that ScopeExit uses PP macros and relies on Boost.Typeof. The latest version can is here: http://boost-consulting.com/vault/index.php?action=downloadfile&filename=sc… It's available also at http://tinyurl.com/2z6qg2 Online documentation is here: http://194.6.223.221/~nasonov/scope_exit-0.04/libs/scope_exit/doc/html/inde… >From the review guidelines here: http://boost.org/more/formal_review_process.htm ... Boost mailing list members are encouraged to submit Formal Review comments: * Publicly on the mailing list. * Privately to the Review Manager. Private comments to a library submitter may be helpful to her or him, but won't help the Review Manager reach a decision, so the other forms are preferred. 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. Thanks in advance to every for your participation in this review.

[SVN] Mime types on check in
by Robert Ramey 16 Aug '07

16 Aug '07

I'm having problems checking in a couple of file types: *.vcproj // text xml for VC projects *.sln // text xml for VC solutions These don't appear in my local SVN configuration. And the pre-commit script is complaining about them. Could this be fixed please? Robert Ramey

pool allocator question
by Steve Kettle 15 Aug '07

15 Aug '07

I have a question about the memory pool allocation that boost implements. Suppose we do the following: std::vector<int, boost::pool_allocator<int> > v; for (int i = 0; i < 10; ++i) v.push_back(-1); And the std::vector<int> is implemented so that it starts out with reserved space of 1 and doubles space every time. So At the end of the above loop v will have size 10 and reserved size 16. Does the boost allocator mean that there will memory arrays lieing around of size 1,2,4,8 that can be reused ? Eg if you do this: std::vector<int, boost::pool_allocator<int> > v; for (int i = 0; i < 10; ++i) v.push_back(-1); std::vector<int, boost::pool_allocator<int> > v2; for (int i = 0; i < 8; ++i) v2.push_back(-1); There will be no system call needed to get more memory - v2 will just reuse the memory in the pool_allocator<int> ? Thanks. Steve. --------------------------------- Take the Internet to Go: Yahoo!Go puts the Internet in your pocket: mail, news, photos & more.

[rfc] proposal to add enable_if_defined to Boost.Utility
by Stjepan Rajko 15 Aug '07

15 Aug '07

Hello, I have found the following little snippet of code quite useful (it is modeled closely after enable_if, but it enables if the given type has been defined, kind of like enable_if + HAS_XXX but simpler and more general). I am curious whether you think this functionality is useful in general, whether the implementation is OK, and whether you think it might be useful to add it to the Utility library (if the functionality is not somewhere else in boost already): // if T is a valid type enable_if_defined result is Result, otherwise specialization failure template<typename T, typename Result=void> struct enable_if_defined { typedef Result type; }; struct void_; // if we need to test for multiple types, we can use all_of template<typename T0=void_, typename T1=void_, typename T2=void_, typename T3=void_, typename T4=void_, typename T5=void_> struct all_of { }; Some examples of how I've been using it: /// Example 1: specialize a template if the type has a trait: template<typename T, typename Enable=void> struct producer_category_of { }; // if T has the producer_category trait, use it to specify producer_category_of template<typename T> struct producer_category_of<T, typename detail::enable_if_defined<typename T::producer_category >::type > { typedef typename T::producer_category type; }; /// Example 2: specialize a type if the type has a couple of metafunctions defined for it: template<typename T, typename Enable=void> struct is_producer : public boost::false_type {}; // If T has both producer_category_of and producer_type_of specified, it is_producer template<typename T> struct is_producer<T, typename detail::enable_if_defined<detail::all_of< typename producer_category_of<T>::type, typename produced_type_of<T>::type > >::type > : public boost::true_type {}; There is some overlap between the proposed enable_if_defined with the existing enable_if in combination with mpl's HAS_XXX. Advantages of enable_if_defined: * unlike enable_if+HAS_XXX, there is no need to define a separate metafunction for each trait to be tested * enable_if_defined can be used to test any type expression that will work with SFINAE Disadvantages of enable_if_defined: * there is no corresponding disable_if_defined * can't be directly used with MPL - if you need a boolean metafunction corresponding to an enable_if_defined, then you do need to define one. * probably not compatible with as many compilers as enable_if+HAS_XXX Any feedback welcome - if this is not a good approach please tell me why so I can stop using it. Thanks, Stjepan
