RRD structures managed by dictionaries (#13646)
* rrdset - in progress
* rrdset optimal constructor; rrdset conflict
* rrdset final touches
* re-organization of rrdset object members
* prevent use-after-free
* dictionary dfe supports also counting of iterations
* rrddim managed by dictionary
* rrd.h cleanup
* DICTIONARY_ITEM now is referencing actual dictionary items in the code
* removed rrdset linked list
* Revert "removed rrdset linked list"
This reverts commit 690d6a588b4b99619c2c5e10f84e8f868ae6def5.
* removed rrdset linked list
* added comments
* Switch chart uuid to static allocation in rrdset
Remove unused functions
* rrdset_archive() and friends...
* always create rrdfamily
* enable ml_free_dimension
* rrddim_foreach done with dfe
* most custom rrddim loops replaced with rrddim_foreach
* removed accesses to rrddim->dimensions
* removed locks that are no longer needed
* rrdsetvar is now managed by the dictionary
* set rrdset is rrdsetvar, fixes https://github.com/netdata/netdata/pull/13646#issuecomment-1242574853
* conflict callback of rrdsetvar now properly checks if it has to reset the variable
* dictionary registered callbacks accept as first parameter the DICTIONARY_ITEM
* dictionary dfe now uses internal counter to report; avoided excess variables defined with dfe
* dictionary walkthrough callbacks get dictionary acquired items
* dictionary reference counters that can be dupped from zero
* added advanced functions for get and del
* rrdvar managed by dictionaries
* thread safety for rrdsetvar
* faster rrdvar initialization
* rrdvar string lengths should match in all add, del, get functions
* rrdvar internals hidden from the rest of the world
* rrdvar is now acquired throughout netdata
* hide the internal structures of rrdsetvar
* rrdsetvar is now acquired through out netdata
* rrddimvar managed by dictionary; rrddimvar linked list removed; rrddimvar structures hidden from the rest of netdata
* better error handling
* dont create variables if not initialized for health
* dont create variables if not initialized for health again
* rrdfamily is now managed by dictionaries; references of it are acquired dictionary items
* type checking on acquired objects
* rrdcalc renaming of functions
* type checking for rrdfamily_acquired
* rrdcalc managed by dictionaries
* rrdcalc double free fix
* host rrdvars is always needed
* attempt to fix deadlock 1
* attempt to fix deadlock 2
* Remove unused variable
* attempt to fix deadlock 3
* snprintfz
* rrdcalc index in rrdset fix
* Stop storing active charts and computing chart hashes
* Remove store active chart function
* Remove compute chart hash function
* Remove sql_store_chart_hash function
* Remove store_active_dimension function
* dictionary delayed destruction
* formatting and cleanup
* zero dictionary base on rrdsetvar
* added internal error to log delayed destructions of dictionaries
* typo in rrddimvar
* added debugging info to dictionary
* debug info
* fix for rrdcalc keys being empty
* remove forgotten unlock
* remove deadlock
* Switch to metadata version 5 and drop
chart_hash
chart_hash_map
chart_active
dimension_active
v_chart_hash
* SQL cosmetic changes
* do not busy wait while destroying a referenced dictionary
* remove deadlock
* code cleanup; re-organization;
* fast cleanup and flushing of dictionaries
* number formatting fixes
* do not delete configured alerts when archiving a chart
* rrddim obsolete linked list management outside dictionaries
* removed duplicate contexts call
* fix crash when rrdfamily is not initialized
* dont keep rrddimvar referenced
* properly cleanup rrdvar
* removed some locks
* Do not attempt to cleanup chart_hash / chart_hash_map
* rrdcalctemplate managed by dictionary
* register callbacks on the right dictionary
* removed some more locks
* rrdcalc secondary index replaced with linked-list; rrdcalc labels updates are now executed by health thread
* when looking up for an alarm look using both chart id and chart name
* host initialization a bit more modular
* init rrdlabels on host update
* preparation for dictionary views
* improved comment
* unused variables without internal checks
* service threads isolation and worker info
* more worker info in service thread
* thread cancelability debugging with internal checks
* strings data races addressed; fixes https://github.com/netdata/netdata/issues/13647
* dictionary modularization
* Remove unused SQL statement definition
* unit-tested thread safety of dictionaries; removed data race conditions on dictionaries and strings; dictionaries now can detect if the caller is holds a write lock and automatically all the calls become their unsafe versions; all direct calls to unsafe version is eliminated
* remove worker_is_idle() from the exit of service functions, because we lose the lock time between loops
* rewritten dictionary to have 2 separate locks, one for indexing and another for traversal
* Update collectors/cgroups.plugin/sys_fs_cgroup.c

* Update collectors/cgroups.plugin/sys_fs_cgroup.c
Co-authored-by: Vladimir Kobal <vlad@prokk.net>
* Update collectors/proc.plugin/proc_net_dev.c
Co-authored-by: Vladimir Kobal <vlad@prokk.net>
* fix memory leak in rrdset cache_dir
* minor dictionary changes
* dont use index locks in single threaded
* obsolete dict option
* rrddim options and flags separation; rrdset_done() optimization to keep array of reference pointers to rrddim;
* fix jump on uninitialized value in dictionary; remove double free of cache_dir
* addressed codacy findings
* removed debugging code
* use the private refcount on dictionaries
* make dictionary item desctructors work on dictionary destruction; strictier control on dictionary API; proper cleanup sequence on rrddim;
* more dictionary statistics
* global statistics about dictionary operations, memory, items, callbacks
* dictionary support for views - missing the public API
* removed warning about unused parameter
* chart and context name for cloud
* chart and context name for cloud, again
* dictionary statistics fixed; first implementation of dictionary views - not currently used
* only the master can globally delete an item
* context needs netdata prefix
* fix context and chart it of spins
* fix for host variables when health is not enabled
* run garbage collector on item insert too
* Fix info message; remove extra "using"
* update dict unittest for new placement of garbage collector
* we need RRDHOST->rrdvars for maintaining custom host variables
* Health initialization needs the host->host_uuid
* split STRING to its own files; no code changes other than that
* initialize health unconditionally
* unit tests do not pollute the global scope with their variables
* Skip initialization when creating archived hosts on startup. When a child connects it will initialize properly
