fix: Balance channel stuck forever due to logic dead lock (#31202)
issue: #30816

cause balance channel will stuck until leader view catch up the current
target, then start to unsub the old delegator. which make sure that the
new delegator can provide search before release old delegator. but
another logic in segment_checker skip loading segment during balance
channel. so during balance channel, if query node crash, new delegator
can't catch up target forever, then stuck forever.

This PR remove the rule that skip loading segment during balance channel
to avoid the logic dead lock here.

Integration test

This folder contains the integration test for Milvus components.

How to run integration test locally

Integration test still need some thirdparty components to start:

cd [milvus-folder]/deployments/docker/dev && docker-compose up -d

Run following script to start the full integration test:

cd [milvus-folder]
make milvus # milvus needs to be compiled to make cpp build ready
./scripts/run_intergration_test.sh

If you want to run single test case, you could execute command like this example

# mq, etcd, minio ready before
cd [milvus-folder]
source scripts/setenv.sh
cd tests/integration/[testcase-folder]/
go test -run "$testCaseName^" -testify.m "$subTestifyCaseName^" -race -v

Using suite

MiniClusterandMiniClusterSuite` provides lots of comment preset tool function to execute intergration test.

It is recommend to add a new test with testify/suite


import (
    // ...
    "github.com/milvus-io/milvus/tests/integration"
)

type NewSuite struct {
    integration.MiniClusterSuite
}


// Setups and teardowns, optional if no custom logic needed
// example to suite setup & teardown, same logic applies to test setup&teardown

func (s *NewSuite) SetupSuite() {
    s.MiniClusterSuite.SetupSuite()
    // customized setup
}

func (s *NewSuite) TearDownSuite() {
    s.MiniClusterSuite.TearDownSuite()
    // customized teardown
}

New folder for each new scenario

It's a known issue that integration test cases run in same process might affect due to some singleton component not fully cleaned.

As a temp solution, test cases are separated into different packages to run independently.
