beorn7 b82bcfe55f Add a package promauto that provides auto-registering metrics 
Finally, I found an easy solution to provide the "evil"
auto-registration without getting death threats from the wardens of Go
purity. The reasoning can be found in the package's doc comment.

beorn7 d892fd2b51 Add test to expose interface upgrade bug 
In principle, we needed to iterate through all permutations, mirroring
the same that is happening in the code. For lack of time, I only
picked one of the cases currently buggy.

As said, this really needs code generation, should we ever find
ourselves touching this again.

Fix delegator return value for single hijacker
 2018-02-02 15:21:57 +01:00
Torin Sandall 44a8a1218c Fix delegator return value for single hijacker 
Previously, the pickDelegator function was not returning a
*hijackerDelegator so the return value did not implement the Hijacker
interface. As a result, code that attempts to hijack the connection
would fail when using a type assertion.

All the other cases returned the hijackerDelegator correctly.

Create goroutines adaptively during metrics gathering

beorn7 4957f7bba4 Add a safety goroutine budget 
This makes sure we don't spin up a possibly infinite number of
goroutines in `Gather`, which could theoretically happen with unlucky
scheduling.

Merge pull request #367 from prometheus/beorn7/counter 
Make Counter faster for simple Inc or Add with an integer
 2018-01-19 19:46:57 +01:00
beorn7 a2facc3074 Iterate on a proposed performance improvement for counters 
Original discussion see
https://github.com/prometheus/client_golang/pull/362 .

Assuming that the most frequently used method of a `Gauge` is `Set`
and the most frequently used method of a `Conuter` is `Inc`, this
separates the implementation of both metric types. `Inc` and integral
`Add` of a counter is now handled in a separate `uint64`. This would
create a race in `Set`, but luckily, there is no `Set` anymore in a
counter.

All attempts to solve above race (to use the same idea for a `Gauge`)
slow down `Set`, So we just stick with the old implementation
(formerly `value`) for `Gauge`.
