Greetings Boost Developers and Users,
It's my pleasure to announce that the review of Ion Gaztañagas' Move library starts May 10th and lasts until May 24th, 2010, unless an extension occurs.
What is it? ===========
The Boost.Move library would supply an emulated C++1x Move semantics interface, aka RValue References, allowing for a wide variety of easy to use and easy to add in optimization abilities.
The most used function it would add would be:
val_b = boost::move( val_a );
Which would move val_a to val_b; val_a should not be used after this line. This semantic allows for a vast amount of optimizations, especially in regards to temporaries, see the documentation for further examples and use.
Other patterns emulated are && rvalue references for functions/members and constructors. There are also a number of STL containers in the sandbox that support move semantics using this library for higher efficiency.
Getting the library ===================
The latest version of this library may be downloaded from
SVN: http://svn.boost.org/svn/boost/sandbox/move/
and the docs may be viewed here
Docs: http://igaztanaga.drivehq.com/libs/move/doc/html/index.html
and do note, this library is header-only and is designed to be absolutely generic to be useful in all areas of C++ programming.
Writing a review ================
If you feel this is an interesting library, then please submit your review to the developer list (preferably), or to the review manager.
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.
Special considerations ======================
If you want or need a primer on the subject, please look at the working draft for C++1x. This linked site has also been shown to be quite useful in describing move usefulness:
Want Speed? Pass by Value.: http://cpp-next.com/archive/2009/08/want-speed-pass-by-value/ Move It With Rvalue References: http://cpp-next.com/archive/2009/09/move-it-with-rvalue-references/
And there are further links in that series, but those two will get you started in the domain.
Best regards,
OvermindDL1, Review Manager (Boost.Move)
There have been a couple of review submissions so far, so at this point I will keep the review on track for its normal ending period, thus it ends tomorrow night. I will go through the reviews and create an overall summary shortly thereafter (I already have time set aside for Tuesday for this). Do note, thus far there have been a few issues brought up about this library, I will see how these continue, but you may expect me to ask for feedback on them as there seems to be a possible conditional acceptance for this library, and at least one (gcc related) bug-fix due to how this library implements something that is not well defined in the standard. If at all possible, please finish up discussion soon, but do not feel rushed, I can delay the final decision, this is an important library for older compilers and it needs to be very well fleshed out.
