2016-11-22Compare size before data when ordering cache bucket entriesJulian Andres Klode
This has the effect of significantly reducing actual string comparisons, and should improve the performance of FindGrp a bit, although it's hardly measureable (callgrind says it uses 10% instructions less now).
2016-03-24Set hidden visibility for StringViewJulian Andres Klode
This avoids templates using StringView to be exported, such as std::vector<StringView*>::emplace_back(). Gbp-Dch: ignore
2016-01-15string_view: Drop constexpr constructor for standard compatibilityJulian Andres Klode
APT::StringView is supposed to be a temporary measure, until support for the standardized string_view is widely available. Introducing additional unstandardized features just makes porting to the standard version harder. The constexpr constructor also won't have any real effect on most systems, as the compiler will happily optimise the strlen() call away for constant strings. Gbp-Dch: ignore
2016-01-15provide a constexpr char[] overload for APT::StringViewDavid Kalnischkies
The commit also adds a few trivial tests Git-Dch: Ignore
2016-01-15return correct position in APT::StringView::(r)findDavid Kalnischkies
The position returned is supposed to be the position of the character counted from the start of the string, but if we used the substr calling overloads the skipped over prefix wasn't considered. The pos parameter of rfind had also the wrong semantic.
2016-01-08operator==(char*, StringView) use StringView.operator==Julian Andres Klode
Use the same path for both comparisons, as the operator== path is faster than just calling compare() - it avoids any comparison if the size differs. Gbp-Dch: ignore
2016-01-07StringView: rfind: pos should be end of substr, not startJulian Andres Klode
Gbp-Dch: ignore
2016-01-07StringView: pos argument default should be nposJulian Andres Klode

2016-01-07StringView::rfind(): Call rfind() instead of find() on substJulian Andres Klode
Thanks: Niels Thykier for reporting on IRC Gbp-Dch: ignore
2016-01-07Introduce internal APT::StringView classJulian Andres Klode
The class APT::StringView implements a drop-in replacement for a subset of C++17 std::string_view() features. It will be dropped at a later point and may not be used in public interfaces.
