Category: test Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Beman Dawes (beman_dawes) Summary: Log level names wrong in documentation Initial Comment: The documentation for the Boost Test Library gives incorrect names for at least two of the log levels. On the page http://boost.org/libs/test/doc/components/utf/parameters/log_level.html (entitled "The 'log level' parameter) it lists the log levels "warnings" and "messages", which do not work. By random chance I happened on what appear to be the correct names, "warning" and "message". -- Kevin S.

what's up with regression testing?
by Arkadiy Vertleyb 25 Apr '06

25 Apr '06

Hi all, It seems that the regression testing for CVS HEAD has mostly stopped a while ago: http://tinyurl.com/mrgwh Also, is the RC_1_34_0 being regression tested? If yes, where are the results available? Thanks, Arkadiy

[program_options] variables_map documentation
by Chris Weed 25 Apr '06

25 Apr '06

Hi, The program_options tutorial shows an example using the count member function of variables_map, but I don't see that function in the documentation for variables_map <http://www.boost.org/doc/html/variables_map.html> or in the documentation for abstract_variables_map <http://www.boost.org/doc/html/abstract_variables_map.html> Chris

[property_tree] How can I design a real-world configuration component around ptree?
by Leif.Reichert 24 Apr '06

24 Apr '06

One important part of our Software is a rather sophisticated "ParamTree" (that's our name for property_tree) which comprises all those facilities that Gennadiy suspected the property_tree to more or less focus on: - Runtime parameter facility - Permanent Storage facility - XML Parser (Because we want the format to be human-readable and also editable if need be) I'm not too happy with our ParamTree, so I couldn't wait for the property_tree, whose interface I believe to be elegant and concise. I wanted to redesign our ParamTree around the property_tree, with just a thin wrapper to cater for our following requirements: - The application is multithreaded, so access to the property tree must be thread-safe and iterators from different threads must not interfere (usually done by ref-counting techniques) - It must be possible to navigate towards the root of the tree - In case of acess errors, it must be possible to retrieve the name of the file, from which the data was loaded - The component must have an abstract base class interface I'm well aware that these requirements are not in the spirit of the STL, and would never want them to be part of the property_tree. What I usualy do in these cases is 1. Design the abstract interface 2. Code a small wrapper class that implements the interface with the aid of on aggreagated STL-compliant container, boost::mutex etc. When I sat down to do design such a wrapper for the property_tree, I realized I couldn't. Not because of a property_tree deficiency, so I think, but because of the very nature of the recursive tree structure: I can't have a single class instance with a property_tree at its core, but I would need an instance for every tree node/leaf. However, I have no idea how canI "inject" my own node type into the property_tree or conversely put a wrapper around every ptree? The only viable solution I see at the moment is to take the traditional approach of designing my own node class, that aggregates a multi_index container, a mutex etc. and looking for the most suitable xml parser for building up the tree. Our ParamTree's redesign would hugely benefit from Marcin's excellent ideas, but it would not be using property_tree; and suddenly, I'm in the camp of those who argue towards a boost::xml_parser, an improved multi_index etc., rather than towards a lean component that does it all. Can someone please help me and point out how to design a wrapper around a tree structure such as ptree? I could then further participate in the review based on my experience implementing such a wrapper. Regards Leif

[multi_index] Is it safe to use detail::scope_guard?
by Alexei Alexandrov 24 Apr '06

24 Apr '06

Hi, there is a very nifty thing in multi_index details - the scope_guard. I'm using it but recently I noticed that it's not being used anywhere in the multi_index itself. Is it going to disappear any time soon?

Boost.Python broken in latest CVS
by Ralf W. Grosse-Kunstleve 24 Apr '06

24 Apr '06

Boost.Python doesn't compile anymore after a cvs update (a few minutes ago). The gcc 3.4.2 error is attached. I haven't done any digging yet. It looks like property_map.hpp has not changed recently. The error must be deeper down. I'd be grateful for any clues.

Re: [boost] [Boost Review] Property Tree Library
by Trent Nelson 24 Apr '06

24 Apr '06

> - was the library's design flexible enough? If not, how would you > suggest it should be redesigned to broaden its scope of use? Very promising looking library. I think we've all had to roll some sort of config parser in the past, so there is a lot of potential for this to gain widespread adoption if its functionality exceeds home-grown versions. Two things that I had to roll into my config system: a) ability to include other files b) inline variable expansion, e.g. site.root = c:\dev site.home = ${site.root}\home The former is important for me as I'll often have a lot of common configuration files shared between products, but I don't want client code having to care about opening half a dozen conf files to find a particular setting. Instead, client code opens '<productname>.conf', and that file happens to 'include(...)' all the other config files necessary, The latter is very Java-.properties-esque, but I don't see any reason why it couldn't be used here. It's extremely flexible, especially if you leave evaluation of inline properties to the very last minute, such that you can consult the entire property tree for the corresponding value (rather than expanding the value as soon as you come into contact with it, restricting you to reference values that have been defined before your reference occurs). What are your thoughts on this being included in your library? Anyone else need to do this type of stuff, or would find this useful? Trent. -- http://www.onresolve.com
