Glen, if you can, rebase the patches *before* updating them based on my comments so that it's easier for reviewers to see if my comments have been addressed. (My comments are minor, so they should still be relevant even after rebasing.) Overall the patch set looks good aside from some minor comments that I've given as replies to the patches.

Thanks for a quick review (and thank you, Glen, for working on it).

Junio: I rebased this onto a newer "master". I assume this is a noop for you - I noticed that the RFC versions weren't applied anyway (good). Thanks for the thoughtful review on the last round, all. This is the first non-RFC reroll, and hopefully the last ;) This is basically the RFC v2 with the post-RFC cleanups I've been talking about, plus review comments. I did a decent amount of experimentation with Phillip's alternative config_fn_t signatures, and while I think they make sense in the long term (when we add additional helpers, make structs opaque, etc), they introduce a lot of distracting churn but don't really change the status quo, so I've left them out of this series. A major departure from the RFC is that the large refactoring patches have now been squashed together. If you'd would like to meaningfully range-diff those commits against v2, you can use: git fetch https://github.com/chooglen/git/ config/no-global-unsquashed-cocci which uses the same base as v1 and v2. = Changes since v2 * Rebase onto a newer version of "master" * To accomodate future changes to config_fn_t, use "const struct config_context *ctx" (which has a .kvi member) instead of directly referencing "kvi". * Add appropriate comments to config.h. * .kvi is now const. * Introduce KVI_INIT as a safer default to "= { 0 }". * Incorporate wording suggestions = Description This series removes all global state from config iteration, i.e. parsing config and iterating configsets, by passing config metadata as a "struct key_value_info" to the "config_fn_t" callbacks. This allows us to get rid of: * "the_reader" (formerly "cf", "current_parsing_scope", "current_config_kvi"), and the config.c machinery that maintained it. This only needed to be global because it was read by... * The "current_*" functions that read metadata about the 'current' config value ("current_config_scope", "current_config_name", etc), which are replaced by reading values from the "struct key_value_info" passed to the callbacks. As a result: * Config iterating code can be moved to into its own library with few modifications. C.f. libification efforts [1]. * The config iterating code can be safely called in parallel. * We expose and fix instances where the "current_*" functions were being called outside of config callbacks. We've had this idea of doing this "config_fn_t" refactor for a long time [2], but we've never attempted it because we wanted to avoid churn. After attempting it, though, I'm quite convinced that this is the right way forward for config, since the lack of global state makes things much easier to reason about. The churn is also quite manageable: * The vast majority of changes can be handled with cocci. * The few cases that aren't covered by cocci have obvious fixes. * The change is simple enough for in-flight topics to perform and conflicts will be caught at build time anyway. To avoid _future_ churn (if we want to change config_fn_t again), I opted to pass a config_context arg instead of using key_value_info directly. We can make changes we want to that arg while leaving the signature untouched. = Patch overview * 1-3/12 add the "ctx" parameter to the config_fn_t signature. * 4-9/12 converts the config.c machinery off "config_reader.config_kvi" and "config_reader.source" and onto ctx->kvi. We convert the config.c machinery from "config_reader" to "kvi" one-by-one: configsets, then files, then CLI. To exercise the "kvi" arg as soon as possible, we convert from current_*() to "kvi" as soon as it is available. For example, in 4/12 "kvi" is available only in configsets, so we convert the current_*() call sites that are only reached via configsets and leave the others untouched. This means that we have a mix of current_*() and "kvi" in the middle, but auditing the changes is relatively easy, since you only need to verify that a callback isn't relying on the "kvi" arg before it is available, and that current_*() and "kvi" give the same value. * 6-7/12 squashes some bugs where builtin/config.c was calling the current_*() API outside of config callbacks. The "kvi" plumbing doesn't just make the bugs apparent, it also provides an obvious way to fix the bugs (by injecting "kvi" into the right places in builtin/config.c). These would have been nontrivial to fix if we were still using global state. * 10-12/12 remove config_reader by taking advantage of "kvi" and doing some other light plumbing. = Alternatives considered Ævar suggested in [3] that we might be able to do the refactor incrementally by having both the old "config_fn_t" and the new "config_fn_t with kvi", which lets us convert some of config iterating (e.g. configsets) without touching the others (e.g. config parsing). I experimented with that for a bit, and it turned out that doing it all at once is actually less work because we don't have to worry about the case where the same "config_fn_t" is used in both git_config() and git_config_from_file(). Jonathan Tan suggested in [4] that to reduce churn, we might be able to convert many of the config_fn_t-s to the config set API before attempting this refactor. But (hopefully), these patches show that the churn is manageable even without this preparatory step.

To reduce the dependence on "config_reader.source", add a new "key_value_info.path" member and use that instead of - "config_source.path". + "config_source.path". This allows us to remove a "struct config_reader + *" field from "struct config_include_data", which will subsequently + allow us to remove "struct config_reader" entirely.
