Awesome Go for Lantern

Cool libraries, frameworks, tips and tricks and anything that can be useful to share.

Inspired by awesome-go, for Lantern.

General

General tools, hacks and techniques with wide usage

• Preeny - Make it easier to interact with services locally. It can disable fork(), rand(), and alarm() and can convert a server application to a console one.
• Ratelimit - Simple, thread-safe Go rate-limiter.

Networking

• Gopacket - Provides packet processing capabilities for Go.

Network Analysis Tools

Tools for interference detection, probing and network analysis in general

• Netalyzr
• OONI
• Zmap
• NDT

Testing

Testing utilities and libraries

• Go-fuzz - Randomized testing (fuzzing). Mainly applicable to packages that parse complex inputs (both text and binary).
• Stress - The stress utility is intended for catching of episodic failures. It runs a given process in parallel in a loop and collects any failures.

Network-specific testing

Libraries for network testing.

• Linkio - Network link speed simulation for Reader/Writer interfaces.
• Toxiproxy - Proxy to simulate network and system conditions for automated tests.
• Comcast - Simulation of bad network connections.
• Gor - HTTP traffic replay in real-time. Replay traffic from production to staging and dev environments. Test code on real user sessions in an automated and repeatable fashion.
• netem - Network Emulation functionality for testing protocols by emulating the properties of wide area networks. The current version emulates variable delay, loss, duplication and re-ordering.

HTTP Load testing

Tools to generate HTTP traffic

• Boom - Similiar to Apache Bench but much simpler!
• Vegeta - More features!

Code Checking

Tools for checking code style and related

• Errcheck - Checking for unchecked errors in go programs.
• Golint - A linter for Go source code.
• GoMetaLinter - Concurrently runs a whole bunch of linters.

Code Analysis

Static code analysis tools that will help you gain insight of the codebase

• Oracle - The go oracle is a source analysis tool that answers questions about Go programs.

Code Refactoring

Refactoring tools specific for Go

• Gorename - Precise type-safe renaming of identifiers in Go source code.
• Gomvpkg - Move go packages, updating import declarations.
• Goimports - Update Go import lines, adding missing ones and removing unreferenced ones.
• Eg - Example-based refactoring tool (better instructions running it).

Dynamic Analysis Tools

Tools to inspect and study the program behavior at runtime

• Race detection - go test -race
• GC tracing - GODEBUG=gctrace=1 go run <file.go>
• Scheduler tracing (info) - GODEBUG=schedtrace=1000 go run <file.go>
• Generic tracing (info) - The capability is compiled into all programs always, and is enabled on demand -- when tracing is disabled it has minimal runtime overhead. That is, the trace can be obtained from a server in production serving live traffic. For visualization, use Google's trace viewer, or type the URL chrome://tracing for an embedded UI in Chrome.
• panicparse - Groups similar goroutines and colorizes stack dump.
