From 02f79ea7a7953423c95e942e39a416ca99d4e273 Mon Sep 17 00:00:00 2001 From: 0x524a Date: Tue, 2 Dec 2025 22:21:20 -0500 Subject: [PATCH] refactor: enhance code clarity and maintainability across multiple files - Updated comments to improve clarity and adhere to best practices in ascii.go, main.go, and diagnostics. - Removed unnecessary linter directives for improved readability in imaging.go and ptz.go. - Reformatted function signatures and added helper calls in tests for consistency and clarity. - Enhanced error handling and logging consistency in various server files, ensuring better maintainability. --- cmd/onvif-cli/ascii.go | 2 +- cmd/onvif-cli/main.go | 11 ++++++---- cmd/onvif-diagnostics/main.go | 14 ++++++------ cmd/onvif-server/main.go | 4 +++- internal/soap/soap.go | 4 ++-- server/imaging.go | 4 ++-- server/imaging_test.go | 17 ++++++++------- server/ptz.go | 4 ++-- server/ptz_test.go | 18 ++++++++++----- server/server.go | 2 +- server/soap/handler_test.go | 5 +++-- server/types.go | 41 ++++++++++++++++++----------------- 12 files changed, 70 insertions(+), 56 deletions(-) diff --git a/cmd/onvif-cli/ascii.go b/cmd/onvif-cli/ascii.go index 8a29540..4ce3eba 100644 --- a/cmd/onvif-cli/ascii.go +++ b/cmd/onvif-cli/ascii.go @@ -70,7 +70,7 @@ func ImageToASCII(imageData []byte, config ASCIIConfig) (string, error) { // imageToASCIIFromImage is the core conversion function. // -//nolint:gocyclo // Image to ASCII conversion has high complexity due to multiple pixel processing paths +//nolint:gocyclo,lll // Image to ASCII conversion has high complexity due to multiple pixel processing paths func imageToASCIIFromImage(img image.Image, config ASCIIConfig, format string) (string, error) { //nolint:unparam // format reserved for future use // Validate configuration if config.Width <= 0 { diff --git a/cmd/onvif-cli/main.go b/cmd/onvif-cli/main.go index fe9f04d..f44cfb6 100644 --- a/cmd/onvif-cli/main.go +++ b/cmd/onvif-cli/main.go @@ -280,6 +280,7 @@ func (c *CLI) performDiscoveryOnInterface(interfaceName string) ([]*discovery.De if err != nil { return nil, fmt.Errorf("discovery failed: %w", err) } + return devices, nil } @@ -614,11 +615,13 @@ func (c *CLI) inspectRTSPStream(streamURI string) map[string]interface{} { // Use rtspeek library for detailed stream inspection ctx, cancel := context.WithTimeout( context.Background(), -
