Adds new package that can be used by client and server RPC endpoints to
facilitate monitoring based off of a logger
clean up old code
small comment about write
rm old comment about minsize
rename to Monitor
Removes connection logic from monitor command
Keep connection logic in endpoints, use a channel to send results from
monitoring
use new multisink logger and interfaces
small test for dropped messages
update go-hclogger and update sink/intercept logger interfaces
Adds nomad monitor command. Like consul monitor, this command allows you
to stream logs from a nomad agent in real time with a a specified log
level
add endpoint tests
Upgrade go-hclog to latest version
The current version of go-hclog pads log prefixes to equal lengths
so info becomes [INFO ] and debug becomes [DEBUG]. This breaks
hashicorp/logutils/level.go Check function. Upgrading to the latest
version removes this padding and fixes log filtering that uses logutils
Check
AgentMonitor is an endpoint to stream logs for a given agent. It allows
callers to pass in a supplied log level, which may be different than the
agents config allowing for temporary debugging with lower log levels.
Pass in logWriter when setting up Agent
Golang 1.13 is pickier with importpaths and aliasing and fails
compilation currently.
Here, for go-msgpack dependency, we use upstream ugorji/go with a single
change
23165f7bc3
.
For consistency and to ease noticing descripency, I made ugorji/go and
hashicorp/go-msgpack reference the same sha.
This is a dependency management update and has no functional change to
product.
* ar: refactor network bridge config to use go-cni lib
* ar: use eth as the iface prefix for bridged network namespaces
* vendor: update containerd/go-cni package
* ar: update network hook to use TODO contexts when calling configurator
* unnecessary conversion
This upgrades hcl2 library dependency to pick up
https://github.com/hashicorp/hcl2/pull/113 .
Prior to this change, parsing and decoding array attributes containing
invalid errors (e.g. references to unknown variables) are silently
dropped, with `cty.Unknown` being assigned to the bad element. Rather
than showing a type/meaningful error from hcl2, we get a very decrypted
error message from msgpack layer trying to handle `cty.unknown`.
This ensures that we propagate diagnostics correctly and report
meaningful errors to users.

Our testing so far indicates that ugorji/go/codec maintains backward
compatiblity with the version we are using now, for purposes of Nomad
serialization.
Using latest ugorji/go allows us to get back to using upstream library,
get get the optimizations benefits in RPC paths (including code
generation optimizations).
ugorji/go introduced two significant changes:
* time binary format in debb8e2d2e. Setting `h.BasicHandle.TimeNotBuiltin = true` restores old behavior
* ugorji/go started honoring `json` tag as well:
v1.1.4 is the latest but has a bug in handling RawString that's fixed in
d09a80c1e0
.
* client/metrics: modified metrics to use (updated) client copy of allocation instead of (unupdated) server copy
* updated armon/go-metrics to address race condition in DisplayMetrics
