I am seeing the following error on latest 2.14-stable 0f54fd4f14144884d24614c4626f63518ff5d1a1 when running spec.
It is only happens when running the spec on the build system's build where starting the mongo server and running spec are executed by a script. It might be specific environment. The issue does not happen when running on the interactive mode manually.
An error occurred in an `after(:context)` hook.
Failure/Error: raise "Deployment server version not known - check that connection to deployment succeeded"
RuntimeError:
Deployment server version not known - check that connection to deployment succeeded
# ./spec/support/cluster_config.rb:42:in `fcv_ish'
# ./spec/stress/connection_pool_timing_spec.rb:17:in `block (2 levels) in <top (required)>'
It seems that this error happens on the following part when @server_version is nil.
spec/support/cluster_config.rb
...
def server_version
determine_cluster_config
@server_version
end
...
def fcv_ish
if server_version.nil?
raise "Deployment server version not known - check that connection to deployment succeeded"
end
...
There is a logic @server_version to be set on the following part.
spec/support/cluster_config.rb
...
def determine_cluster_config
...
@single_server = client.cluster.servers_list.length == 1
build_info = client.database.command(buildInfo: 1).first
@server_version = build_info['version']
...
Interestingly the line build_info = client.database.command(buildInfo: 1).first raises an error. As a result the line @server_version = build_info['version'] is not executed.
Checking the command method, I see the following warning, and
p "[DEBUG] lib/mongo/database.rb command end result: #{result}"
is not executed.
lib/mongo/database.rb
def command(operation, opts = {})
p "[DEBUG] lib/mongo/database.rb command start"
opts = opts.dup
...
result = client.send(:with_session, opts) do |session|
server = selector.select_server(cluster, nil, session)
op = Operation::Command.new(
:selector => operation.dup,
:db_name => name,
:read => selector,
:session => session
)
op.execute(server, client: client, options: execution_opts)
end
p "[DEBUG] lib/mongo/database.rb command end result: #{result}"
result
"[DEBUG] lib/mongo/database.rb command start"

Do you have any idea to fix it?
Thank you.
