Easy wiki spam removal?
by Rene Rivera 10 May '06

10 May '06

Simple question... Is there a really easy way to remove spam from the wiki? And I mean something like a "rollback to X version" or "delete Y revision" button? There's a whole bunch of pages just affected and copy+paste from the last good revision into a new revision is just painfully slow for doing it many times. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo

Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Kevin J Bluck (kbluck) Assigned to: Nobody/Anonymous (nobody) Summary: program_options: format_paragraph assert fails on long line Initial Comment: Boost 1.33.1, MSVC 8.0 When format_paragraph() in options_description.cpp attempts to format a line that will wrap because it is > 80 chars, it causes an assert failure in the standard library string iterator's operator+=(). The offending po:: code line is options_description.cpp Line 361: if (line_begin + (line_length - indent) > par_end) ... Relevant call stack attached. My guess is that the assert is complaining that the + operation has produced an iterator past the string's end(); this code seems to be assuming that the iterator object is a pointer. I believe it is officially undefined to advance an iterator past end(). One way of getting around this might be to use std::distance instead of comparing the iterators directly. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1485069&group_… ------------------------------------------------------- Using Tomcat but need to do more?

[Range] Expected complexity constraints
by David Abrahams 09 May '06

09 May '06

I note that the range library still supports the following: * treating null-terminated strings as Ranges where the complexity of end(s) is O(N) * treating pairs of non-random-access iterators as Ranges where the complexity of size(p) is O(N) In my view both of these would ideally be eliminated. The argument for the latter is slightly weaker because of prcedent in the std, although the LWG is considering removing it. Possible alternatives distinguish the ranges that actually give the expected complexity: a. Provide separate concepts for O1EndRange and O1SizeRange b. Provide traits to detect has_o1_end and has_o1_size Probably you'd want to do both. By the way, you can get back O(1) for end(s) where s is a null-terminated string if you allow the end iterator to have a different type from the begin iterator... but those ranges don't play well with the standard algorithms. -- Dave Abrahams Boost Consulting www.boost-consulting.com

I am quite new to programming, however, I decided to install the boost library as it looks very good. The first two lines of my program are: #include "boost/filesystem/operations.hpp" #include "boost/filesystem/fstream.hpp" Yet when I include the statement: using boost::filesystem; just after, I get an error message saying: "error C2873: 'boost::filesystem' : symbol cannot be used in a using-declaration" I am using Microsoft Visual Studio 2005. Where could I have gone wrong? I have tried to find documentation that will help, but I haven't found anything.
