Thanks for the review on the previous round!
This v2 is mostly a reorganization of v1, largely based off Jonathan's
feedback in [1]. As such, nearly all of v1's cover letter still applies
(except for the "Patch Overview" section [2]) so this cover letter omits
those bits that have already been covered. The first non-RFC version will
get rerolled with full cover letter.
Since a lot of this series removes the config_reader stuff from
gc/config-parsing-cleanup, it might be useful to diff this with "master"
right before that:
git diff 0a8c337394 HEAD -- config.c
= Changes since v1
* Reorganize patches in a (hopefully) easier-to-review way.
* Squash bugs in builtin/config.c that became apparent during the refactor.
These could have been fixed in v1, but they dropped off my radar.
= Patch overview
* 1-5/14 add the "kvi" parameter to the config_fn_t signature. These are
mostly unchanged from v1.
* 6-11/14 converts the config.c machinery off "config_reader.config_kvi"
and "config_reader.source" and onto the new "kvi" arg. Most of the
changes from v1 are here.
In v1, we converted all of the config.c machinery first, making the "kvi"
arg available everywhere before the refactor. Thus we could convert all
callers of the current_*() API to the "kvi" arg in a single step. However
(as Jonathan rightfully pointed out), some of the changes to the
machinery are non-trivial, and it's quite difficult to spot bugs in the
intermediate patches.
In v2, 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 6/14 "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 (compared to v1's machinery changes), 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.
* 8-9/14 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.
* 12-14/14 remove config_reader by taking advantage of the "kvi" parameter
and doing some other light plumbing.

## Commit message ##
- config: remove current_config_(line|name|origin_type)
+ config.c: pass kvi in configsets
- Trivially replace current_config_(line|name|origin_type) by reading the
- corresponding values from "struct key_value_info". This includes some
- light "kvi" plumbing for builtin/config.c, and for *origin_type,
- splitting out a function that turns "enum config_origin_type" into the
- human-readable string that callbacks actually want.
+ Trivially pass "struct key_value_info" to config callbacks in
+ configset_iter(). Then, in config callbacks that are only used with
+ configsets, use the "kvi" arg to replace calls to current_config_*(),
+ and delete current_config_line() because it has no remaining callers.
- Signed-off-by: Glen Choo <chooglen@xxxxxxxxxx>
+ This leaves builtin/config.c and config.c as the only remaining users of
+ current_config_*().

## Commit message ##
- config: use kvi for config files
+ config: provide kvi with config files
- Plumb "struct key_value_info" and use "kvi_fn()" when parsing config
- files. As a result, "config_reader.kvi" is now always set correctly, so
- we can remove "config_reader.scope" (but not the ".source" member since
- that's still needed by some non-parsing machinery). This requires
- plumbing an additional "enum config_scope" arg through
- "git_config_from_file_with_options()" and the underlying machinery to
- make up for the fact that "struct key_value_info" has a ".scope" member,
- but "struct config_source" does not.
+ Refactor out the configset logic that caches "struct config_source" and
+ "enum config_scope" as a "struct key_value_info", and use it to pass the
+ "kvi" arg to config callbacks when parsing config files. Get the "enum
+ config_scope" value by plumbing an additional arg through
+ git_config_from_file_with_options() and the underlying machinery.
- To handle "include" directives correctly, use push/pop semantics for
- "config_reader.config_kvi" (instead of "set" semantics) like we do for
- "config_reader.source". Otherwise, "config_reader.config_kvi" won't be
- set correctly when we finish parsing an included config file and we want
- to "pop" it to resume parsing the original file. This distinction only
- matters while there is a global "kvi", i.e. it will be obsolete at the
- end of the series.
+ We do not exercise the "kvi" arg yet because the remaining
+ current_config_*() callers may be used with config_with_options(), which
+ may read config from parameters, but parameters don't pass "kvi" yet.

## Commit message ##
- config.c: use kvi for CLI config
+ config.c: provide kvi with CLI config
- Plumb "struct key_value_info" and use "kvi_fn()" when parsing CLI
- config. Do this by refactoring out and reusing the logic that sets the
- "struct key_value_info" members when caching CLI config in a configset.
+ Refactor out kvi_from_param() from the logic that caches CLI config in
+ configsets, and use it to pass the "kvi" arg to config callbacks when
+ parsing CLI config. Now that "kvi" is always present when config
+ machinery calls config callbacks, plumb "kvi" so that we can replace
+ nearly all calls to current_config_*(). (The exception is an edge case
+ where trace2/*.c calls current_config_scope(). That will be handled in a
+ later commit.) Note that this results in "kvi" containing a different,
+ more complete set of information than the mocked up "struct
+ config_source" in git_config_from_parameters().
- This lets us get rid of the fake "struct config_source" in
- "git_config_from_parameters()", so we now only have to maintain one
- implementation. Additionally, this plumbing also reveals that
- "git_config_parse_parameter()" hasn't been setting either
- "the_reader.source" or "the_reader.config_kvi", so any calls to
- "current_*" would either BUG() or return *_UNKNOWN values.
+ Plumbing "kvi" reveals a few places where we've been doing the wrong
+ thing:
- Also, get rid of the BUG() checks that forbid setting ".config_kvi" and
- ".source" at the same time, since we will run afoul of that check. They
- will soon be unnecessary when we remove ".source".
+ * git_config_parse_parameter() hasn't been setting config source
+ information, so plumb "kvi" there too.
+
+ * "git config --get-urlmatch --show-scope" iterates config to collect
+ values, but then attempts to display the scope after config iteration.
+ Fix this by copying the "kvi" arg in the collection phase so that it
+ can be read back later. This means that we can now support "git config
+ --get-urlmatch --show-origin" (we don't allow this combination of args
+ because of this bug), but that is left unchanged for now.
+
+ * "git config --default" doesn't have config source metadata when
+ displaying the default value. Fix this by treating the default value
+ as if it came from the command line (e.g. like we do with "git -c" or
+ "git config --file"), using kvi_from_param().

## Commit message ##
- config: remove config_reader from configset_add_value
+ config.c: remove config_reader from configsets
- Since we now get "kvi" from the config callback, we can stop passing it
- via "*data". Now "struct config_reader" has no more references, so get
- rid of it.
+ Remove the last usage of "struct config_reader" from configsets by
+ copying the "kvi" arg instead of recomputing "kvi" from
+ config_reader.source. Since we no longer need to pass both "struct
+ config_reader" and "struct config_set" in a single "void *cb", remove
+ "struct configset_add_data" too.

config.c, but this refactor is okay because this function has only ever
been (and probably ever will be) used internally by config.c.
- This removes the last user of "config_reader.source", so remove it too.
+ As a result, the_reader isn't used anywhere, so "struct config_reader"
+ is obsolete (it was only intended to be used with the_reader). Remove
+ them.
