* | 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.

* | 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.

* Cleanup: SmallMemmove nullify should also be limited to 15 bytesGravatar Martijn Vels2022-09-30
| | | | | | | | | The current implementation correctly copies up to 15 bytes of data, but the nullify code clears up to 16 bytes, which was likely motivated by the assumption that the length indicator is always the last byte. This changes limits the nullify to 15 bytes as well removing this layout specific assumption from cord.h, making future platform specific internal layout changes easier to land.
