1b08d827a4 Rename GetMeter() to Meter() (#357) 2019-11-26 09:54:05 -08:00

9a2484c373 Implement support for NonAbsolute Measurement MaxSumCount (#335)
* Add tests for nonabsolute and varying sign values

* Implement support for NonAbsolute Measurement MaxSumCount

Previously, the MaxSumCount aggregator failed to work correctly with
negative numbers (e.g. MeasureKind Alternate()==true).

* Pass NumberKind to MaxSumCount New() function

Allows it to set the initial state (current.max) to the correct value
based on the NumberKind.

* Revert extraneous local change

* Pass full descriptor to msc New()

This is analagous to the DDSketch New() constructor

* Remember to run make precommit first

* Add tests for empty checkpoint of MaxSumCount aggregator

An empty checkpoint should have Sum() == 0, Count() == 0 and Max()
still equal to the numberKind.Minimum()

* Return ErrEmptyDataSet if no value set by the aggregator

Remove TODO from stdout exporter to ensure that if a maxsumcount or
ddsketch aggregator returns ErrEmptyDataSet from Max(), then the
entire record will be skipped by the exporter.

Added tests to ensure the exporter doesn't send any updates for
EmptyDataSet checkpoints - for both ddsketch and maxsumcount.

* Relayout Aggreggator struct to ensure int64s are 8-byte aligned

On 32-bit architectures, Go only guarantees that primitive
values are aligned to a 4 byte boundary. Atomic operations on 32-bit
machines require 8-byte alignment.

See https://github.com/golang/go/issues/599

* Addressing PR comments

The use of Minimum() for the default uninitialized Maximum value means
that in the unlikely condition that every recorded value for a measure
is equal to the same NumberKind.Minimum(), then the aggregator's Max()
will return ErrEmptyDataSet

3362421c9b Drop the registry package (#130)
This is to shrink the PR #100.

The only place where the registry.Variable type was used was metrics,
so just inline that type into its only user. The use of the
registry.Variable type in core.Key was limited to the Name field.

The stats package also used the registry.Variable type, but seems that
also only the Name field was used and the package is going to be
dropped anyway.

Event interface - it is used nowhere.

670b0365d8 Make tag.Map a concrete type. (#89)
This is to make tag.Map an immutable type, so it is safe to use
concurrently. The safety is not yet fully achieved because of the
functions returning contents of the map (Value and Foreach). The
functions give callers an access to core.Value objects, which contain
a byte slice, which has pointer like semantics. So to avoid accidental
changes, we will need to copy the value if it is of BYTES type.
