-# Netdata ini config files
-
-Configuration files `netdata.conf` and `stream.conf` are Netdata ini files.
-
-## Motivation
-
-The whole idea came up when we were evaluating the documentation involved
-in maintaining a complex configuration system. Our intention was to give
-configuration options for everything imaginable. But then, documenting all
-these options would require a tremendous amount of time, users would have
-to search through endless pages for the option they need, etc.
-
-We concluded then that **configuring software like that is a waste of time
-and effort**. Of course there must be plenty of configuration options, but
-the implementation itself should require a lot less effort for both the
-developers and the users.
-
-So, we did this:
-
-1. No configuration is required to run Netdata
-2. There are plenty of options to tweak
-3. There is minimal documentation (or no at all)
-
-## Why this works?
-
-The configuration file is a `name = value` dictionary with `[sections]`.
-Write whatever you like there as long as it follows this simple format.
-
-Netdata loads this dictionary and then when the code needs a value from
-it, it just looks up the `name` in the dictionary at the proper `section`.
-In all places, in the code, there are both the `names` and their
-`default values`, so if something is not found in the configuration
-file, the default is used. The lookup is made using B-Trees and hashes
-(no string comparisons), so they are super fast. Also the `names` of the
-settings can be `my super duper setting that once set to yes, will turn the world upside down = no`
-
-- so goodbye to most of the documentation involved.
-
-Next, Netdata can generate a valid configuration for the user to edit.
-No need to remember anything or copy and paste settings. Just get the
-configuration from the server (`/netdata.conf` on your Netdata server),
-edit it and save it.
-
-Last, what about options you believe you have set, but you misspelled?
-When you get the configuration file from the server, there will be a
-comment above all `name = value` pairs the server does not use.
-So you know that whatever you wrote there, is not used.

- * This section manages ini config files, like netdata.conf and stream.conf
- *
- * It is organized like this:
- *
- * struct config (i.e. netdata.conf or stream.conf)
- * .sections = a linked list of struct section
- * .mutex = a mutex to protect the above linked list due to multi-threading
- * .index = an AVL tree of struct section
- *
- * struct section (i.e. [global] or [health] of netdata.conf)
- * .value = a linked list of struct config_option
- * .mutex = a mutex to protect the above linked list due to multi-threading
- * .value_index = an AVL tree of struct config_option
- *
- * struct config_option (ie. a name-value pair for each ini file option)
- *
- * The following operations on name-value options are supported:
- * SET to set the value of an option
- * SET DEFAULT to set the value and the default value of an option
- * GET to get the value of an option
- * EXISTS to check if an option exists
- * MOVE to move an option from a section to another section, and/or rename it
- *
- * GET and SET operations are provided for the following data types:
- * STRING
- * NUMBER (long long)
- * FLOAT (long double)
- * BOOLEAN (false, true)
- * BOOLEAN ONDEMAND (false, true, auto)
- *
- * GET and SET operations create struct config_option, if it is not already present.
- * This allows netdata to run even without netdata.conf and stream.conf. The internal
- * defaults are used to create the structure that should exist in the ini file and the config
- * file can be downloaded from the server.
- *
- * Also 2 operations are supported for the whole config file:
- *
- * LOAD To load the ini file from disk
- * GENERATE To generate the ini file (this is used to download the ini file from the server)
- *
- * For each option (name-value pair), the system maintains 4 flags:
- * LOADED to indicate that the value has been loaded from the file
- * USED to indicate that netdata used the value
- * CHANGED to indicate that the value has been changed from the loaded value or the internal default value
- * CHECKED is used internally for optimization (to avoid an strcmp() every time GET is called).
- *
- * TODO:
- * 1. The linked lists and the mutexes can be removed and the AVL trees can become DICTIONARY.
- * This part of the code was written before we add traversal to AVL.
- *
- * 2. High level data types could be supported, to simplify the rest of the code:
- * MULTIPLE CHOICE to let the user select one of the supported keywords
- * this would allow users see in comments the available options
- *
- * SIMPLE PATTERN to let the user define netdata SIMPLE PATTERNS
- *
- * 3. Sorting of options should be supported.
- * Today, when the ini file is downloaded from the server, the options are shown in the order
- * they appear in the linked list (the order they were added, listing changed options first).
- * If we remove the linked list, the order they appear in the AVL tree will be used (which is
- * random due to simple_hash()).
- * Ideally, we support sorting of options when generating the ini file.
- *
- * 4. There is no free() operation. So, memory is freed on netdata exit.
- *
- * 5. Avoid memory fragmentation
- * Since entries are created from multiple threads and a lot of allocations are required
- * for each config_option, fragmentation can be a problem for IoT.
- *
- * 6. Although this way of managing options is quite flexible and dynamic, it wastes memory
- * for the names of the options. Since most of the option names are static, we could provide
- * a method to allocate only the dynamic option names.
