# This file defines all supported Apache per-directory configuration options. The
# build system automatically generates the corresponding Apache module boilerplate
# code from the definitions in this file.
#
# Main configuration options are not defined in this file, but are defined in
# src/apache2_module/Configuration.cpp instead.
#
# The following boilerplate code is generated:
#
#  * command_rec array members (ConfigGeneral/AutoGeneratedDefinitions.cpp.cxxcodebuilder)
#  * Global (server-wide) struct fields (ServerConfig/AutoGeneratedStruct.cpp.cxxcodebuilder)
#  * Per-directory struct (DirConfig/AutoGeneratedStruct.h.cxxcodebuilder)
#  * Per-directory struct fields initialization code (DirConfig/AutoGeneratedCreateFunction.cpp.cxxcodebuilder)
#  * Per-directory struct fields merging code (DirConfig/AutoGeneratedMergeFunction.cpp.cxxcodebuilder)
#  * Struct field setter functions (ConfigGeneral/AutoGeneratedSetterFuncs.cpp.cxxcodebuilder)
#  * Apache module <-> Core headers serialization code (ConfigGeneral/AutoGeneratedHeaderSerialization.cpp.cxxcodebuilder)
#
# Options:
#
#  * name - The configuration option name. Required.
#  * context - The context in which this configuration option is valid.
#              Allowed values:
#              :global -- Global configuration
#              :application -- Per-application configuration (default)
#              :location -- Per-location/per-request configuration
#  * htaccess_context - If `context` is set to :location, then this
#              defines whether -- and in which -- .htaccess contexts it is allowed.
#              This is an array of `OR_` macro names.
#              Default: ['OR_OPTIONS']
#  * type - This configuration option's value type. Allowed types:
#           :string, :integer, :flag, :string_array, :string_keyval, :string_set
#  * field - The name that should be used for the auto-generated field in
#            the configuration structure. Defaults to the configuration
#            name without the 'Passenger' prefix, and in camel case. Set this
#            to nil if you do not want a structure field to be auto-generated.
#  * min_value - If `type` is :integer, then this specifies the minimum
#                allowed value. When nil (the default), there is no minimum.
#  * default - A static default value. Set during configuration merging,
#              and reported in the tracking code that generates the
#              configuration manifest.
#  * default_expr - If `default` is set, but you don't want the value
#                   to appear in the autogenerated code (e.g. you want the
#                   autogenerated code to contain the corresponding constant name)
#                   when you can use this option to override what gets written in the
#                   autogenerated code.
#  * dynamic_default - If this option has a default, but it's dynamically inferred
#              (and not a static value) then set this option to a human-readable
#              description that explains how the default is dynamically inferred.
#              Reported in the tracking code that generates the configuration
#              manifest.
#  * desc - A description for this configuration option. Required.
#  * header - The name of the corresponding CGI header. By default CGI header
#             generation code is automatically generated, using the configuration
#             option's name in uppercase as the CGI header name.
#             Setting this to nil will disable auto-generation of CGI header
#             generation code. You are then responsible for writing CGI header
#             passing code yourself in Hooks.cpp.
#  * header_expression - The expression to be passed to `addHeader()`.
#  * function - If nil, a setter function will be automatically generated. If
#               non-nil, must be the name of the setter function.
#  * obsolete - Whether this is an obsolete option. Defaults to false.
#  * obsoletion_message - If the `obsolete` option is true, then
#               specify the obsoletion warning message here. This is optional:
#               there is a default obsoletion message.
