Revert "[config] Move global config alongside core configuration" (#32659)
Reverts grpc/grpc#30788 (it breaks grpc_objc_bazel_test (see https://github.com/grpc/grpc/pull/30788#issuecomment-1476372187) and also seems to be breaking some other internal stuff).pull/32663/head^2

|

|
// How to use global configuration variables:
|
||||||
|
//
|
||||||
|
// Defining config variables of a specified type:
|
||||||
|
// GPR_GLOBAL_CONFIG_DEFINE_*TYPE*(name, default_value, help);
|
||||||
|
//
|
||||||
|
// Supported TYPEs: BOOL, INT32, STRING
|
||||||
|
//
|
||||||
|
// It's recommended to use lowercase letters for 'name' like
|
||||||
|
// regular variables. The builtin configuration system uses
|
||||||
|
// environment variable and the name is converted to uppercase
|
||||||
|
// when looking up the value. For example,
|
||||||
|
// GPR_GLOBAL_CONFIG_DEFINE(grpc_latency) looks up the value with the
|
||||||
|
// name, "GRPC_LATENCY".
|
||||||
|
//
|
||||||
|
// The variable initially has the specified 'default_value'
|
||||||
|
// which must be an expression convertible to 'Type'.
|
||||||
|
// 'default_value' may be evaluated 0 or more times,
|
||||||
|
// and at an unspecified time; keep it
|
||||||
|
// simple and usually free of side-effects.
|
||||||
|
//
|
||||||
|
// GPR_GLOBAL_CONFIG_DEFINE_*TYPE* should not be called in a C++ header.
|
||||||
|
// It should be called at the top-level (outside any namespaces)
|
||||||
|
// in a .cc file.
|
||||||
|
//
|
||||||
|
// Getting the variables:
|
||||||
|
// GPR_GLOBAL_CONFIG_GET(name)
|
||||||
|
//
|
||||||
|
// If error happens during getting variables, error messages will
|
||||||
|
// be logged and default value will be returned.
|
||||||
|
//
|
||||||
|
// Setting the variables with new value:
|
||||||
|
// GPR_GLOBAL_CONFIG_SET(name, new_value)
|
||||||
|
//
|
||||||
|
// Declaring config variables for other modules to access:
|
||||||
|
// GPR_GLOBAL_CONFIG_DECLARE_*TYPE*(name)
|
||||||
|
//
|
||||||
|
// * Caveat for setting global configs at runtime
|
||||||
|
//
|
||||||
|
// Setting global configs at runtime multiple times is safe but it doesn't
|
||||||
|
// mean that it will have a valid effect on the module depending configs.
|
||||||
|
// In unit tests, it may be unpredictable to set different global configs
|
||||||
|
// between test cases because grpc init and shutdown can ignore changes.
|
||||||
|
// It's considered safe to set global configs before the first call to
|
||||||
|
// grpc_init().
|
||||||
|
|
||||||
|
// --------------------------------------------------------------------
|
||||||
|
// How to customize the global configuration system:
|
||||||
|
//
|
||||||
|
// How to read and write configuration value can be customized.
|
||||||
|
// Builtin system uses environment variables but it can be extended to
|
||||||
|
// support command-line flag, file, etc.
|
||||||
|
//
|
||||||
|
// To customize it, following macros should be redefined.
|
||||||
|
//
|
||||||
|
// GPR_GLOBAL_CONFIG_DEFINE_BOOL
|
||||||
|
// GPR_GLOBAL_CONFIG_DEFINE_INT32
|
||||||
|
// GPR_GLOBAL_CONFIG_DEFINE_STRING
|
||||||
|
//
|
||||||
|
// These macros should define functions for getting and setting variable.
|
||||||
|
// For example, GPR_GLOBAL_CONFIG_DEFINE_BOOL(test, ...) would define two
|
||||||
|
// functions.
|
||||||
|
//
|
||||||
|
// bool gpr_global_config_get_test();
