Overview

There have been some suggestions for api-incompatible improvements recently especially with regards to the new python generator.

This page is here to keep track of such proposals so that they aren't lost. Discussion about the items happens on the xcb mailing list and the status, comments and different points of view should be tracked here.

Cleanup iterators stuff [Christoph Pfister / new]

  • Reasons: reduce confusion because sometimes you have to advance the pointer in the iterator struct yourself and sometimes you must not
  • Proposal: provide _next() functions for every kind of iterator so you never have to modify the content of an iterator yourself

Normalization of naming with regards to numbers [Thomas Hunger / new]

  • Proposal: always have numbers stick to the previous word (handle them as lower case letters)
  • Reasons: consistency

Remove *request_t and the opcodes from the public API [Christoph Pfister (originally by Thomas Hunger) / new]

  • Reasons: less lines needed to keep stable / not needed for using xcb / compile time speedup

Cleanup iterators stuff [Christoph Pfister / postponed till next major API breaking release]

  • Reasons: it should be possible to reduce the number of *iterator_t structs and helper functions which would decrease the size of the headers and the code
  • Proposal: if elements occupy adjacent memory positions you have two functions: one to get the number of elements and one to get a pointer to the first element (you advance by incrementing the pointer); else you have an iterator struct which contains only a pointer to the data and three functions: one to get the number of elements, one to get an iterator and one to advance it
  • Caveats: not checked whether all stuff can be handled this way
