To cache Logging clients effectively in a multi-project TUI environment, standardizing on a project-aware thread-safe map cache with a `sync.Mutex` prevents expensive credential discovery (~300ms) and connection overhead on every log stream, while ensuring different projects resolve to their correct cached clients. Using `context.Background()` avoids connection teardowns due to transient request-level context cancellations, and a no-op `Close()` preserves the shared connections. +**Action:** Use project-aware maps for caching GCP clients that are bound to a specific project ID upon creation, and ensure proper test isolation by resetting global maps. + ## 2026-03-07 - GCP Execution & Project Client Caching **Learning:** Incomplete caching of GCP client wrappers in remaining packages (`job/execution` and `project`) meant that loading job execution tables or searching for GCP projects still suffered from repetitive credential discovery and connection establishment, degrading TUI interactivity. Standardizing stateful `GCPClient` caching via thread-safe lazy-initialization with `sync.Mutex` completely eliminates this overhead. **Action:** Ensure all Cloud SDK APIs used in the application leverage the stateful lazy-initialization cached client pattern with proper thread-safety. diff --git a/internal/run/api/log/client.go b/internal/run/api/log/client.go index c9e767a..6b7fb03 100644 --- a/internal/run/api/log/client.go +++ b/internal/run/api/log/client.go @@ -19,13 +19,21 @@ package log import ( "context" "fmt" + "sync" "cloud.google.com/go/logging" "cloud.google.com/go/logging/logadmin" "github.com/JulienBreux/run-cli/internal/run/api/client" + "golang.org/x/oauth2/google" "google.golang.org/api/option" ) +var ( + logClientMu sync.Mutex + logClients = make(map[string]LogAdminClientWrapper) + logClientCreds *google.Credentials +) + // Client defines the interface for Logging operations. type Client interface { Entries(ctx context.Context, opts ...interface{}) EntryIterator @@ -77,16 +85,30 @@ type GCPClient struct { // NewGCPClient creates a new GCPClient. func NewGCPClient(ctx context.Context, projectID string) (Client, error) { - creds, err := client.FindDefaultCredentials(ctx, logging.ReadScope) - if err != nil { - return nil, fmt.Errorf("failed to find default credentials: %w", err) + logClientMu.Lock() + defer logClientMu.Unlock() + + if c, ok := logClients[projectID]; ok { + return &GCPClient{client: c}, nil } - c, err := createLogAdminClient(ctx, projectID, option.WithCredentials(creds)) + bgCtx := context.Background() + + if logClientCreds == nil { + creds, err := client.FindDefaultCredentials(bgCtx, logging.ReadScope) + if err != nil { + return nil, fmt.Errorf("failed to find default credentials: %w", err) + } + logClientCreds = creds + } + + c, err := createLogAdminClient(bgCtx, projectID, option.WithCredentials(logClientCreds)) if err != nil { return nil, err } + logClients[projectID] = c + return &GCPClient{client: c}, nil } @@ -101,7 +123,8 @@ func (c *GCPClient) Entries(ctx context.Context, opts ...interface{}) EntryItera } func (c *GCPClient) Close() error { - return c.client.Close() + // Close is a no-op because the underlying connection pool is shared and cached. + return nil } // GCPEntryIterator wraps logadmin.EntryIterator. diff --git a/internal/run/api/log/log_test.go b/internal/run/api/log/log_test.go index 62d51c0..86a24cf 100644 --- a/internal/run/api/log/log_test.go +++ b/internal/run/api/log/log_test.go @@ -245,6 +245,15 @@ func (m *MockLogAdminClientWrapper) Close() error { } func TestGCPClient(t *testing.T) { + resetCache := func() { + logClientMu.Lock() + logClients = make(map[string]LogAdminClientWrapper) + logClientCreds = nil + logClientMu.Unlock() + } + resetCache() + defer resetCache() + origFindCreds := client.FindDefaultCredentials origCreateClient := createLogAdminClient defer func() { @@ -257,6 +266,9 @@ func TestGCPClient(t *testing.T) { } t.Run("NewGCPClient_Success", func(t *testing.T) { + resetCache() + defer resetCache() + createLogAdminClient = func(ctx context.Context, projectID string, opts ...option.ClientOption) (LogAdminClientWrapper, error) { return &MockLogAdminClientWrapper{ EntriesFunc: func(ctx context.Context, opts ...logadmin.EntriesOption) EntryIterator { @@ -280,6 +292,9 @@ func TestGCPClient(t *testing.T) { }) t.Run("NewGCPClient_AuthError", func(t *testing.T) { + resetCache() + defer resetCache() + client.FindDefaultCredentials = func(ctx context.Context, scopes ...string) (*google.Credentials, error) { return nil, errors.New("auth failed") } @@ -290,6 +305,9 @@ func TestGCPClient(t *testing.T) { }) t.Run("NewGCPClient_ClientCreationError", func(t *testing.T) { + resetCache() + defer resetCache() + client.FindDefaultCredentials = func(ctx context.Context, scopes ...string) (*google.Credentials, error) { return &google.Credentials{}, nil }
