It is a descriptive rather than prescriptive doc; that is, we want to +describe how things work in practice rather than explicitly recommending any +particular process or changes to the current process. + +Here we document how the project makes decisions for discussions +(with or without patches), in scale larger than an individual patch +series (which is fully covered by the SubmittingPatches document). + + +Larger Discussions (with patches) +--------------------------------- +As with discussions on an individual patch series, starting a larger-scale +discussion often begins by sending a patch or series to the list. This might +take the form of an initial design doc, with implementation following in later +iterations of the series (for example, +link:https://lore.kernel.org/git/0169ce6fb9ccafc089b74ae406db0d1a8ff8ac65.1688165272.git.steadmon@google.com/[adding unit tests] or +link:https://lore.kernel.org/git/20200420235310.94493-1-emilyshaffer@google.com/[config-based hooks]), +or it might include a full implementation from the beginning. +In either case, discussion progresses the same way for an individual patch series, +until consensus is reached or the topic is dropped. + + +Larger Discussions (without patches) +------------------------------------ +Occasionally, larger discussions might occur without an associated patch series. +These may be very large-scale technical decisions that are beyond the scope of +even a single large patch series, or they may be more open-ended, +policy-oriented discussions (examples: +link:https://lore.kernel.org/git/ZZ77NQkSuiRxRDwt@nand.local/[introducing Rust] +or link:https://lore.kernel.org/git/YHofmWcIAidkvJiD@google.com/[improving submodule UX]). +In either case, discussion progresses as described above for general patch series. + +For larger discussions without a patch series or other concrete implementation, +it may be hard to judge when consensus has been reached, as there are not any +official guidelines. If discussion stalls at this point, it may be helpful to +restart discussion with an RFC patch series (such as a partial, unfinished +implementation or proof of concept) that can be more easily debated. + +When consensus is reached that it is a good idea, the original +proposer is expected to coordinate the effort to make it happen, +with help from others who were involved in the discussion, as +needed. + +For decisions that require code changes, it is often the case that the original +proposer will follow up with a patch series, although it is also common for +other interested parties to provide an implementation (or parts of the +implementation, for very large changes). + +For non-technical decisions such as community norms or processes, it is up to +the community as a whole to implement and sustain agreed-upon changes. +The project leadership committe (PLC) may help the implementation of +policy decisions. + + +Other Discussion Venues +----------------------- +Occasionally decision proposals are presented off-list, e.g. at the semi-regular +Contributors' Summit. While higher-bandwidth face-to-face discussion is often +useful for quickly reaching consensus among attendees, generally we expect to +summarize the discussion in notes that can later be presented on-list. For an +example, see the thread +link:https://lore.kernel.org/git/AC2EB721-2979-43FD-922D-C5076A57F24B@jramsay.com.au/[Notes +from Git Contributor Summit, Los Angeles (April 5, 2020)] by James Ramsay. + +We prefer that "official" discussion happens on the list so that the full +community has opportunity to engage in discussion.

Things apply cleanly but does not build or test fails, or things do +not apply cleanly. ++ +In the latter case, you have textual or semantic conflicts coming from +the difference between the old base and the base you used to build in +(1). Identify what caused the breakages (e.g., a topic or two may have +merged since the base used by (2) until the base used by (1)). ++ +Check out the latest 'origin/master' (which may be newer than the base +used by (2)), "merge --no-ff" the topics you newly depend on in there, +and use the result of the merge(s) as the base, rebuild the series and +test again.
