- * ADAPTIVE RE-SORTABLE LIST
- * This structure allows netdata to read a file of NAME VALUE lines
- * in the fastest possible way.
- *
- * It maintains a linked list of all NAME (keywords), sorted in the
- * same order as found in the source data file.
- * The linked list is kept sorted at all times - the source file
- * may change at any time, the list will adapt.
- *
- * The caller:
- *
- * 1. calls arl_create() to create a list
- *
- * 2. calls arl_expect() to register the expected keyword
- *
- * Then:
- *
- * 3. calls arl_begin() to initiate a data collection iteration.
- * This is to be called just ONCE every time the source is re-scanned.
- *
- * 4. calls arl_check() for each line read from the file.
- *
- * Finally:
- *
- * 5. calls arl_free() to destroy this and free all memory.
- *
- * The program will call the processor() function, given to
- * arl_create(), for each expected keyword found.
- * The default processor() expects dst to be an unsigned long long *.
- *
- * LIMITATIONS
- * DO NOT USE THIS IF THE A NAME/KEYWORD MAY APPEAR MORE THAN
- * ONCE IN THE SOURCE DATA SET.

-// How backends work in netdata:
-//
-// 1. There is an independent thread that runs at the required interval
-// (for example, once every 10 seconds)
-//
-// 2. Every time it wakes, it calls the backend formatting functions to build
-// a buffer of data. This is a very fast, memory only operation.
-//
-// 3. If the buffer already includes data, the new data are appended.
-// If the buffer becomes too big, because the data cannot be sent, a
-// log is written and the buffer is discarded.
-//
-// 4. Then it tries to send all the data. It blocks until all the data are sent
-// or the socket returns an error.
-// If the time required for this is above the interval, it starts skipping
-// intervals, but the calculated values include the entire database, without
-// gaps (it remembers the timestamps and continues from where it stopped).
-//
-// 5. repeats the above forever.

-/*
- * procfile is a library for reading kernel files from /proc
- *
- * The idea is this:
- *
- * - every file is opened once with procfile_open().
- *
- * - to read updated contents, we rewind it (lseek() to 0) and read again
- * with procfile_readall().
- *
- * - for every file, we use a buffer that is adjusted to fit its entire
- * contents in memory, allowing us to read it with a single read() call.
- * (this provides atomicity / consistency on the data read from the kernel)
- *
- * - once the data are read, we update two arrays of pointers:
- * - a words array, pointing to each word in the data read
- * - a lines array, pointing to the first word for each line
- *
- * This is highly optimized. Both arrays are automatically adjusted to
- * fit all contents and are updated in a single pass on the data:
- * - a raspberry Pi can process 5.000+ files / sec.
- * - a J1900 celeron processor can process 23.000+ files / sec.

-// TODO
-//
-// 1. the default tracking cookie expires in 1 year, but the persons are not
-// removed from the db - this means the database only grows - ideally the
-// database should be cleaned in registry_db_save() for both on-disk and
-// on-memory entries.
-//
-// Cleanup:
-// i. Find all the PERSONs that have expired cookie
-// ii. For each of their PERSON_URLs:
-// - decrement the linked MACHINE links
-// - if the linked MACHINE has no other links, remove the linked MACHINE too
-// - remove the PERSON_URL
-//
-// 2. add protection to prevent abusing the registry by flooding it with
-// requests to fill the memory and crash it.
-//
-// Possible protections:
-// - limit the number of URLs per person
-// - limit the number of URLs per machine
-// - limit the number of persons
-// - limit the number of machines
-// - [DONE] limit the size of URLs
-// - [DONE] limit the size of PERSON_URL names
-// - limit the number of requests that add data to the registry,
-// per client IP per hour
-//
-// 3. lower memory requirements
-//
-// - embed avl structures directly into registry objects, instead of DICTIONARY
-// [DONE for PERSON_URLs, PENDING for MACHINE_URLs]
-// - store GUIDs in memory as UUID instead of char *
-// - do not track persons using the demo machines only
-// (i.e. start tracking them only when they access a non-demo machine)
-// - [DONE] do not track custom dashboards by default
