  24 // IMPORTANT: Before adding a new config value, please read up on naming conventions (see
  25 // code:#NamingConventions)
  26 //
  27 // ==========
  28 // CONTENTS
  29 // ==========
  30 // * How to define config values (see code:#Define)
  31 // * How to access config values (see code:#Access)
  32 // * Naming conventions (see code:#NamingConventions)
  33 //
  34 //
  35 // =====================================
  36 // #Define - Use one of the following macros to define config values. (See code:#DWORDs and code:#Strings)
  37 // =====================================
  38 //
  39 // By default, all macros are DEBUG ONLY. Add the "RETAIL_" prefix to make the config value available in retail builds.
  40 //
  41 // #DWORDs:
  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!
  49 //
  50 // Example: CONFIG_DWORD_INFO(INTERNAL_AllowCrossModuleInlining, W("AllowCrossModuleInlining"), 0, "")
  51 //
  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
  57 //
  58 // Example: CONFIG_DWORD_INFO_EX(INTERNAL_EnableInternetHREFexes, W("EnableInternetHREFexes"), 0, "",
  59 // (CLRConfig::LookupOptions) (CLRConfig::LookupOptions::DontPrependPrefix))
  60 //
  61 // #Strings:
  62 // --------------------------------------------------------------------------
  63 // CONFIG_STRING_INFO(symbol, name, description)
  64 // --------------------------------------------------------------------------
  65 // Defines a string value. Same rules apply as DWORDs.
  66 //
  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.
  71 //
  72 //
  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
  77 // file.
  78 //
  79 //
  80 // ===============================================================
  81 // #NamingConventions
  82 // ===============================================================
  83 // ----------------
  84 // #Symbol - used to access values from the source. (using CLRConfig::<symbol>)
  85 // ----------------
  86 // The symbol for each config value is named as such:
  87 // ### <Class>_<feature area>_<name> ###
  88 //
  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
  93 //
  94 // Examples:
  95 // * INTERNAL_Security_FullAccessChecks
  96 // * UNSUPPORTED_Security_DisableTransparency
  97 // * EXTERNAL_Security_LegacyHMACMode
  98 //
  99 // ----------------
 100 // #Name - the name of the registry value or environment variable that CLRConfig looks up.
 101 // ----------------
 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.
 104 //
 105 // For compatibility reasons, current names do not follow the convention.
 106 //
 107 // Examples:
 108 // * W("INTERNAL_Security_FullAccessChecks")
 109 // * W("UNSUPPORTED_Security_DisableTransparency")
 110 // * W("Security_LegacyHMACMode") <---------------------- (No EXTERNAL prefix)
