Avoid overstepping bounds in config file parsing

2021-02-03T16:43:13Z

Our configuration files are not security relevant, but having a parser which avoids crashing on them even if they are seriously messed up is not a bad idea anyway. It is also a good opportunity to brush up the code a bit avoiding a few small string copies with our string_view.

StringView: Implement operator ""_sv

2020-02-03T11:54:42Z

This allows us to define constexpr string view literals.

Allow comparing string to StringView

2019-06-11T12:45:55Z

Make APT::StringView public

Reformat and sort all includes with clang-format

2017-07-12T11:57:51Z

This makes it easier to see which headers includes what. The changes were done by running git grep -l '#\s*include' \ | grep -E '.(cc|h)$' \ | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/' To modify all include lines by adding a space, and then running ./git-clang-format.sh.

Compare size before data when ordering cache bucket entries

2016-11-22T21:58:19Z

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).

Set hidden visibility for StringView

2016-03-24T14:16:00Z

This avoids templates using StringView to be exported, such as std::vector::emplace_back(). Gbp-Dch: ignore

string_view: Drop constexpr constructor for standard compatibility

2016-01-15T18:18:29Z

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

provide a constexpr char[] overload for APT::StringView

2016-01-15T17:19:16Z

The commit also adds a few trivial tests Git-Dch: Ignore

return correct position in APT::StringView::(r)find

2016-01-15T17:19:16Z

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.
