8 // Unified method of accessing configuration values from environment variables,
9 // registry and config file.
11 // Given any config knob below that looks like this example:
12 // RETAIL_CONFIG_DWORD_INFO(INTERNAL_LogEnable, W("LogEnable"), 0, "Turns on the traditional CLR log.")
15 // --------------------
18 // You can set an environment variable COMPlus_LogEnable=1 to enable it.
20 // See below for more details
22 //*****************************************************************************
24 // IMPORTANT: Before adding a new config value, please read up on naming conventions (see
25 // code:#NamingConventions)
30 // * How to define config values (see code:#Define)
31 // * How to access config values (see code:#Access)
32 // * Naming conventions (see code:#NamingConventions)
35 // =====================================
36 // #Define - Use one of the following macros to define config values. (See code:#DWORDs and code:#Strings)
37 // =====================================
39 // By default, all macros are DEBUG ONLY. Add the "RETAIL_" prefix to make the config value available in retail builds.
42 // --------------------------------------------------------------------------
43 // CONFIG_DWORD_INFO(symbol, name, defaultValue, description)
44 // --------------------------------------------------------------------------
45 // Use this macro to define a basic DWORD value. CLRConfig will look in environment variables (adding
46 // COMPlus_ to the name) for this value. To customize
47 // where CLRConfig looks, use the extended version of the macro below. IMPORTANT: please follow the
48 // code:#NamingConventions for the symbol and the name!
50 // Example: CONFIG_DWORD_INFO(INTERNAL_AllowCrossModuleInlining, W("AllowCrossModuleInlining"), 0, "")
52 // --------------------------------------------------------------------------
53 // CONFIG_DWORD_INFO_EX(symbol, name, defaultValue, description, lookupOptions)
54 // --------------------------------------------------------------------------
55 // To customize where CLRConfig looks to get a DWORD, use the extended (_EX) version of the macro. For a list
56 // of options and their descriptions, see code:CLRConfig.LookupOptions
58 // Example: CONFIG_DWORD_INFO_EX(INTERNAL_EnableInternetHREFexes, W("EnableInternetHREFexes"), 0, "",
59 // (CLRConfig::LookupOptions) (CLRConfig::LookupOptions::DontPrependPrefix))
62 // --------------------------------------------------------------------------
63 // CONFIG_STRING_INFO(symbol, name, description)
64 // --------------------------------------------------------------------------
65 // Defines a string value. Same rules apply as DWORDs.
67 // --------------------------------------------------------------------------
68 // CONFIG_STRING_INFO_EX(symbol, name, description, lookupOptions)
69 // --------------------------------------------------------------------------
70 // Extended version of the String macro. Again, similar to the DWORD extended macro.
73 // ===============================================================
74 // #Access - Use the following overloaded method to access config values.
75 // ===============================================================
76 // From anywhere, use CLRConfig::GetConfigValue(CLRConfig::<symbol>) to access any value defined in this
80 // ===============================================================
82 // ===============================================================
84 // #Symbol - used to access values from the source. (using CLRConfig::<symbol>)
86 // The symbol for each config value is named as such:
87 // ### <Class>_<feature area>_<name> ###
89 // <Class> indicates which of the following buckets the value is in:
90 // * INTERNAL ? this value is for internal (CLR team) use only
91 // * UNSUPPORTED ? this value is available to partners/developers, but is not officially supported
92 // * EXTERNAL ? this value is available for anyone to use and is publicly documented
95 // * INTERNAL_Security_FullAccessChecks
96 // * UNSUPPORTED_Security_DisableTransparency
97 // * EXTERNAL_Security_LegacyHMACMode
100 // #Name - the name of the registry value or environment variable that CLRConfig looks up.
102 // The name of each value is the same as the symbol, with one exception. Names of external values do NOT
103 // contain the EXTERNAL prefix.
105 // For compatibility reasons, current names do not follow the convention.
108 // * W("INTERNAL_Security_FullAccessChecks")
109 // * W("UNSUPPORTED_Security_DisableTransparency")
110 // * W("Security_LegacyHMACMode") <---------------------- (No EXTERNAL prefix)
