* added streaming senders to global stats
* prevent division by zero
* added clock_init() to external C plugins
* added freebsd and macos plugins
* added freebsd and macos to global statistics

- Variable "hostname" going out of scope leaks the storage it points to.
- Null-checking "rd->name" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.

allocations (#12841)
* fix mismatches of the use of the z functions for allocations
* when there was no memory; the original name of the dimensions was freed, and with mismatching deallocator..
* fixed memory leak at rrdeng_load_metric_*() functions
* fixed memory leak on exit of plugins.d parser
* fixed memory leak on plugins and streaming receiver threads exit
* fixed compiler warnings

|
* Add chart filtering in the allmetrics API call
* Fix compilation warnings
* Remove unnecessary function
* Update the documentation

* inject removed events when missing from sqlite
* pass flag
* remove log message
|
|
* Optimize linking of foreach alarms to dimensions.
Keep the write-lock on host but use read-lock for charts because it's
easy to verify that they aren't modified by the linking of foreach
alarms to dimensions.
* Protect alarm log modifications with write-lock.

* Set the thread name for libuv threads to LIBUV_WORKER
* Make sure the dbengine thread has the correct name

* initial attempt at metric correlations
* fix loop
* simplify struct
* change json
* get points from query
* comment
* dont lock the host as much
* add a configuration option to enable/disable metric correlations
* remove KSfbar from header file
* lock charts
* add timeout
* cast multiplication
* add licencing info
* better licencing
* use onewayalloc
* destroy owa

* Try to queue dimension always when:
Trying to clean obsolete charts
If chart has been sent and liveness apparently changed
* delay rotation and skip chart check if not send to cloud
* No need to CLEAR flag during database rotation
Do not clear chart ACLK status for dimension requests
* Change payload_sent to return timestamp of submitted message
* Clear the dimension ACLK flag if we are processing all the charts again
* Check if dimension is already queued to ACLK and ignore it
If queue fails then reset it to retry
Already try to queue the dimension
* Improve dimension cleanup during the retention message calculation
* Change queue_dimension_to_aclk to return void
* If no time range for this dimension then assume it is deleted
* Start streaming for inactive nodes
* Remove dead code
* Correctly report hostname in the access log
* Schedule a dimension deletion without trying to submit a message immediately
* Enable dimension cleanup -- also delete dimension if not found in the dbengine files
Free hostname

After https://github.com/netdata/netdata/pull/12209 per-chart configuration
was used for (a) enabling/disabling a chart, and (b) renaming dimensions.
Regarding the first use case: We already have component-specific
configuration options|flags to finely control how a chart should behave.
Eg. "send charts matching" in streaming, "charts to skip from training"
in ML, etc. If we really need the concept of a disabled chart, we can
add a host-level simple pattern to match these charts.
Regarding the second use case: It's not obvious why we'd need to provide
support for remapping dimension names through a chart-specific configuration
from the core agent. If the need arises, we could add such support at
the right place, ie. a exporter/streaming config section.
This will allow each flag to act indepentendly from each other and
avoid managing flag-state manually at various places, eg:
```
if(unlikely(!rrdset_flag_check(st, RRDSET_FLAG_ENABLED))) {
rrdset_flag_clear(st, RRDSET_FLAG_UPSTREAM_SEND);
rrdset_flag_set(st, RRDSET_FLAG_UPSTREAM_IGNORE);
} ...
```

* rrd: move API structures out of rrddim_volatile
In C, unlike C++, it's not possible to reference a nested structure
from outside this structure.
Since we later want to use rrddim_query_ops and rrddim_collect_ops
separately from rrddim_volatile, move these nested structures out.
* rrd: use opaque handle types for different memory modes
|
|
* check for chart obsoletion on children connections
* use rrdset_is_obsolete
|
|
* one way allocator to speed up context queries
* fixed a bug while expanding memory pages
* reworked for clarity and finally fixed the bug of allocating memory beyond the page size
* further optimize allocation step to minimize the number of allocations made
* implement strdup with memcpy instead of strcpy
* added documentation
* prevent an uninitialized use of owa
* added callocz() interface
* integrate onewayalloc everywhere - apart sql queries
* one way allocator is now used in context queries using archived charts in sql
* align on the size of pointers
* forgotten freez()
* removed not needed memcpys
* give unique names to global variables to avoid conflicts with system definitions
|
|
* filter
* update filter
* queue removed directly
* more
* logging
* cleanup
* cleanup 2
* cleanup 3
* finalize instead of reset
|
|
If memory mode is save, map or ram the set's flags are initialized to 0.
Otherwise, the set is calloc'd which will make the set have 0 flags.
|
|
They are used extensively throughout our code base, and not having
support for them does not generate a thread-safe agent.
