Brian Flad 9fd352a821 Migrate from GitHub HashiBot to GitHub Actions
GitHub HashiBot is being decommissioned. This migrates the crash issue labeling and waiting-reply label removal to GitHub Actions. The stale issue handling is not migrated as neither behavior appears to be actively in use.

Daniel Nephin eb0c0d7740 stream: remove bufferItem.NextLink
Both NextLink and NextNoBlock had the same logic, with slightly
different return values. By adding a bool return value (similar to map
lookups) we can remove the duplicate method.

generate a single debug file for a long duration capture (#10279)
* debug: remove the CLI check for debug_enabled

The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.

Also:
- fix the API client to return errors on non-200 status codes for debug
  endpoints
- improve the failure messages when pprof data can not be collected

Co-Authored-By: Dhia Ayachi <dhia@hashicorp.com>

* remove parallel test runs

parallel runs create a race condition that fail the debug tests

* snapshot the timestamp at the beginning of the capture

- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures
- capture append to the file if it already exist

* Revert "snapshot the timestamp at the beginning of the capture"

This reverts commit c2d03346

* Refactor captureDynamic to extract capture logic for each item in a different func

* snapshot the timestamp at the beginning of the capture

- timestamp used to create the capture sub folder is snapshot only at the beginning of the capture and reused for subsequent captures
- capture append to the file if it already exist

* Revert "snapshot the timestamp at the beginning of the capture"

This reverts commit c2d03346

* Refactor captureDynamic to extract capture logic for each item in a different func

* extract wait group outside the go routine to avoid a race condition

* capture pprof in a separate go routine

* perform a single capture for pprof data for the whole duration

* add missing vendor dependency

* add a change log and fix documentation to reflect the change

* create function for timestamp dir creation and simplify error handling

* use error groups and ticker to simplify interval capture loop

* Logs, profile and traces are captured for the full duration. Metrics, Heap and Go routines are captured every interval

* refactor Logs capture routine and add log capture specific test

* improve error reporting when log test fail

* change test duration to 1s

* make time parsing in log line more robust

* refactor log time format in a const

* test on log line empty the earliest possible and return

Docs for Unix Domain Sockets (#10252)
* Docs for Unix Domain Sockets

There are a number of cases where a user might wish to either 1)
expose a service through a Unix Domain Socket in the filesystem
('downstream') or 2) connect to an upstream service by a local unix
domain socket (upstream).
As of Consul (1.10-beta2) we've added new syntax and support to configure
the Envoy proxy to support this
To connect to a service via local Unix Domain Socket instead of a
port, add local_bind_socket_path and optionally local_bind_socket_mode
to the upstream config for a service:
    upstreams = [
      {
         destination_name = "service-1"
         local_bind_socket_path = "/tmp/socket_service_1"
         local_bind_socket_mode = "0700"
	 ...
      }
      ...
    ]
This will cause Envoy to create a socket with the path and mode
provided, and connect that to service-1
The mode field is optional, and if omitted will use the default mode
for Envoy. This is not applicable for abstract sockets. See
https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/core/v3/address.proto#envoy-v3-api-msg-config-core-v3-pipe
for details
NOTE: These options conflict the local_bind_socket_port and
local_bind_socket_address options. We can bind to an port or we can
bind to a socket, but not both.
To expose a service listening on a Unix Domain socket to the service
mesh use either the 'socket_path' field in the service definition or the
'local_service_socket_path' field in the proxy definition. These
fields are analogous to the 'port' and 'service_port' fields in their
respective locations.
    services {
      name = "service-2"
      socket_path = "/tmp/socket_service_2"
      ...
    }
OR
    proxy {
      local_service_socket_path = "/tmp/socket_service_2"
      ...
    }
There is no mode field since the service is expected to create the
socket it is listening on, not the Envoy proxy.
Again, the socket_path and local_service_socket_path fields conflict
with address/port and local_service_address/local_service_port
configuration entries.
Set up a simple service mesh with dummy services:
socat -d UNIX-LISTEN:/tmp/downstream.sock,fork UNIX-CONNECT:/tmp/upstream.sock
socat -v tcp-l:4444,fork exec:/bin/cat
services {
  name = "sock_forwarder"
  id = "sock_forwarder.1"
  socket_path = "/tmp/downstream.sock"
  connect {
    sidecar_service {
      proxy {
	upstreams = [
	  {
	    destination_name = "echo-service"
	    local_bind_socket_path = "/tmp/upstream.sock"
	    config {
	      passive_health_check {
		interval = "10s"
		max_failures = 42
	      }
	    }
	  }
	]
      }
    }
  }
}
services {
  name = "echo-service"
  port = 4444
  connect = { sidecar_service {} }
Kind = "ingress-gateway"
Name = "ingress-service"
Listeners = [
 {
   Port = 8080
   Protocol = "tcp"
   Services = [
     {
       Name = "sock_forwarder"
     }
   ]
 }
]
consul agent -dev -enable-script-checks -config-dir=./consul.d
consul connect envoy -sidecar-for sock_forwarder.1
consul connect envoy -sidecar-for echo-service -admin-bind localhost:19001

Daniel Nephin 59d201e148 submatview: fix a bug with Store.Get
When info.Timeout is 0, it should have no timeout. Previously it was using a 0 duration timeout
which caused it to return without waiting.

This bug was masked by using a timeout in the tests. Removing the timeout caused the tests to fail.

usagemetrics: add cluster members to metrics API (#10340)
This PR adds cluster members to the metrics API. The number of members per

Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.

Daniel Nephin cec8bc88a9 cmd: remove unnecessary GatedUi
The intent of this struct was to prevent non-json output to stdout. With
the previous cleanup, this can now be done by simply changing the stdout
stream to io.Discard.

This is just one example of why passing around io.Writers for the
streams is better than the UI interface.

Daniel Nephin 2261a469e3 cmd: move agent running message to logs

directly to stdout.

are enabled.

grpc: fix resolver data race
2021-06-02 13:23:27 -04:00
Daniel Nephin 29e93f6338 grpc: fix a data race by using a static resolver
We have seen test flakes caused by 'concurrent map read and map write', and the race detector
reports the problem as well (prevent us from running some tests with -race).

The root of the problem is the grpc expects resolvers to be registered at init time
before any requests are made, but we were using a separate resolver for each test.

This commit introduces a resolver registry. The registry is registered as the single
resolver for the consul scheme. Each test uses the Authority section of the target
(instead of the scheme) to identify the resolver that should be used for the test.
The scheme is used for lookup, which is why it can no longer be used as the unique
key.

This allows us to use a lock around the map of resolvers, preventing the data race.

Daniel Nephin c9bc5f92b7 envoy: fix bootstrap deadlock caused by a full named pipe
Normally the named pipe would buffer up to 64k, but in some cases when a
soft limit is reached, they will start only buffering up to 4k.
In either case, we should not deadlock.

This commit changes the pipe-bootstrap command to first buffer all of
stdin into the process, before trying to write it to the named pipe.
This allows the process memory to act as the buffer, instead of the
named pipe.

Also changed the order of operations in `makeBootstrapPipe`. The new
test added in this PR showed that simply buffering in the process memory
was not enough to fix the issue. We also need to ensure that the
`pipe-bootstrap` process is started before we try to write to its
stdin. Otherwise the write will still block.

Also set stdout/stderr on the subprocess, so that any errors are visible
to the user.
