Avoid constructing ill-formed `std::basic_string_view`

2025-10-27T10:44:56Z

Since libc++19, only `std::char_traits` is defined: https://github.com/llvm/llvm-project/commit/e30a148b098d462d0267c479cd9e4783363c2761 This makes usage of `std::char_traits`, `std::char_traits`, etc invalid. C++20 deduction guides are now used to infer proper `Char` type; while also avoiding being overly specific with `type_traits`. commit_hash:c5ffaef9ef1c8b462d2fdf0e080a43d5cd4c4ca7

StringSplitter: splitting an empty string should always produce exactly one token

2025-10-21T22:00:33Z

Previously, the split operation would produce incorrect results if the bound of the user-provided string overlaps with the address of a default-constructed string. Introduce a sentinel value to ensure that such overlap are no longer possible. Use additional boolean flag to check for the similar problem in the iterator-based version of algorithm. commit_hash:6590787dc4c0319375efa3630a7146e31eed5e89

Use 'size' instead of 'ysize'.

[util] track the lifetime of strings passed through the StripString function family

2025-03-07T21:29:30Z

Specialize StripString functions for the std::string_view and TStringBuf types. An example of erroneous code in which the compiler will be able to detect a problem with the lifetime of temporary string: ``` TStringBuf sb = StripString(TStringBuf{" abc "s}); Use(sb); // segfault ``` commit_hash:ad47648de30fd1a7e59d39a8ec3918fd1484a0ba
