v0.5.0

Adopts Go 1.11 modules.

Improved error reporting in `sqlx` instrumentation

This change updates the sqlx instrumentation. When a DB call returns an error, it sets the db.error field to have the string of the error, fixing a bug where the field might only contain {} instead.

Adding Content-Encoding fields

Added support for content encoding fields to hnynethttp. Now users of the Go beeline will know which requests are gzipped!

Also updated hnypop.DB with context methods, which fixes the pop example.

Add getters for trace / span IDs

Add getter methods to Trace and Span structs.

• func (t *Span) GetTrace() *Trace
• func (t *Span) GetSpanID() string
• func (t *Span) GetParentID() string
• func (t *Trace) GetTraceID() string
• func (t *Trace) GetParentID() string

Add http response fields

Added the HTTP Content-Length and Content-Type values to auto-instrumentation for HTTP spans.

Add more database statistics

Add additional go database stats to hnysql and hnysqlx wrapppers. In go 1.11 and later, we additionally report db.conns_in_use, db.conns_idle, db.wait_count, and db.wait_duration. See https://golang.org/pkg/database/sql/#DB.Stats

Bugfix release

A few small fixes

• added missing Close function to the Stmt type
• renamed echo example binary for using the echo web framework so it doesn't collide with the builtin shell echo command
• updated transaction's QueryxContext to use a span instead of an event

Bugfix release

• Fixed db.error not being added by hnysql and hnysqlx wrappers.
• Reduction in heap allocations when creating a span.

Bugfix release

Fixes bug during initialization where the batch timeout was not correctly set.
