beorn7 03adbe57e4 discovery/marathon: Fix race conditions in test 
The concurrency applied before is in most cases not even needed. With
a cap=1 channel, most tests are much cleaner.

TestMarathonSDRunAndStop was trickier. It could even have blocked
before.

This also includes a general refactoring of the whole file.

Fabian Reinartz d15adfc917 Preserve target state across reloads. 
This commit moves Scraper handling into a separate scrapePool type.
TargetSets only manage TargetProvider lifecycles and sync the
retrieved updates to the scrapePool.

TargetProviders are now expected to send a full initial target set
within 5 seconds. The scrapePools preserve target state across reloads
and only drop targets after the initial set was synced.

Federico Baldo d14d2429ea Minor improvements to ec2 sd: 
1. static credentials replaced with defaults.DefaultChainCredentials.
This change ensures that credentials are sourced form all possible
providers available with the aws sdk,           in the following order:
env variables, shared awsconfig file in user folder, ec2 instance role.

2. Added a few labels: AvailabilityZone, PublicDns, VpcId (if
available), SubnetId (if in Vpc)

Julius Volz d88aea7e6f Fix SD mechanism source prefix handling. 
The prefixed target provider changed a pointerized target group that was
reused in the wrapped target provider, causing an ever-increasing chain
of source prefixes in target groups from the Consul target provider.

We now make this bug generally impossible by switching the target group
channel from pointer to value type and thus ensuring that target groups
are copied before being passed on to other parts of the system.

I tried to not let the depointerization leak too far outside of the
channel handling (both upstream and downstream) because I tried that
initially and caused some nasty bugs, which I want to minimize.

Fix flakey FileSD test.
 2015-08-26 13:25:00 +02:00
Julius Volz 3fd5826589 Fix flakey FileSD test. 
When the test ends, all files matching the watcher's glob are removed
via defer. In that moment, the draining goroutine may still be running
and then detect no files matching the configured glob just before the
test exits.

This is now solved by waiting for the draining goroutine to finish
before leaving the test function and thus causing the deferred file
removal.

otherwise it uses whatever datacenter was set to.
