| | | | | | | | | | | escaping vs unescaping: * Move table documenting escaping conversions to be next to the internal escaping code that implements it. Mention it from the internal _un_escaping code (which reverses it) too. * Centralize the two arrays which map from normal chars to escaped chars (k(WebSafe)Base64Chars), and make bidirectional documentation links between them and their reverse (unescaping) maps (kUn(WebSafe)Base64). * Remove redundant list of escaping/unescaping methods in the public escaping.cc.

* Remove possible UB from CopyRaw()Gravatar Martijn Vels2022-12-07
| | | | | | | This change removes the 'create by single memcpy' CopyRaw() logic to avoid potential UB from the atomic refcount data being included in the memcpy. While we know this works on all supported platforms, it is officially UB, and we should change it to something else. This change changes the CopyRaw() method to explicitly create a (default initialized) instance, initialize `length` and `refcount`, and then memcpy the remaining contents which are trivial uint8_t and CordRep* values.

* Support logging of user-defined types that implement `AbslStringify()`Gravatar Phoebe Liang2022-11-02
| | | | | | | | | If a user-defined type has `AbslStringify()` defined, it will always be used for logging over `operator<<`. `HasAbslStringify` now uses the empty class `UnimplementedSink` for its checks instead of `StringifySink` in order to make it work in cases involving other sinks.

* Reorganize InlineData into an inner Rep structure.Gravatar Martijn Vels2022-10-13
| | | | | | | | | | | | | | | | This moves inlined code around a bit without changing anything bar the names of things. The purpose for all this is that it greatly simplifies the process of adding memory poisining to Cord / InlineData. InlineData can have scoped poison / unpoison regions around the interface, calling into rep for the 'real code'. I.e.: Rep::as_chars() { return &inline_data[1]; } InlineData::as_chars() { Unpoisoned self(this); return rep_.as_chars(); } Likewise, it greatly simplifies intercepting the code for constructors, copy constructors and operator= logic.
