Building from Source

Pre-requisites

• Go
• GolangCI - A meta-linter which runs several linters in parallel
  • To install, follow the local installation instructions
• Yarn - Yarn package manager
  • Run yarn install --frozen-lockfile in the stash/ui/v2.5 folder (before running make generate for first time).

NOTE: You may need to run the go get commands outside the project directory to avoid modifying the projects module file.

Environment

Windows

1. Download and install Go for Windows
2. Download and extract MingW64 (scroll down and select x86_64-posix-seh, dont use the autoinstaller it doesnt work)
3. Search for "advanced system settings" and open the system properties dialog.
   1. Click the Environment Variables button
   2. Under system variables find the Path. Edit and add C:\MinGW\bin (replace with the correct path to where you extracted MingW64).

NOTE: The make command in Windows will be mingw32-make with MingW. For example make pre-ui will be mingw32-make pre-ui

macOS

1. If you don't have it already, install the Homebrew package manager.
2. Install dependencies: brew install go git yarn gcc make

Commands

• make pre-ui - Installs the UI dependencies. Only needs to be run once before building the UI for the first time, or if the dependencies are updated
• make generate - Generate Go and UI GraphQL files
• make fmt-ui - Formats the UI source code
• make ui - Builds the frontend
• make build - Builds the binary (make sure to build the UI as well... see below)
• make docker-build - Locally builds and tags a complete 'stash/build' docker image
• make lint - Run the linter on the backend
• make fmt - Run go fmt
• make it - Run the unit and integration tests
• make validate - Run all of the tests and checks required to submit a PR
• make ui-start - Runs the UI in development mode. Requires a running stash server to connect to. Stash server port can be changed from the default of 9999 using environment variable VITE_APP_PLATFORM_PORT. UI runs on port 3000 or the next available port.

Building a release

1. Run make generate to create generated files
2. Run make ui to compile the frontend
3. Run make build to build the executable for your current platform

Cross compiling

This project uses a modification of the CI-GoReleaser docker container to create an environment where the app can be cross-compiled. This process is kicked off by CI via the scripts/cross-compile.sh script. Run the following command to open a bash shell to the container to poke around:

docker run --rm --mount type=bind,source="$(pwd)",target=/stash -w /stash -i -t stashappdev/compiler:latest /bin/bash

Profiling

Stash can be profiled using the --cpuprofile <output profile filename> command line flag.

The resulting file can then be used with pprof as follows:

go tool pprof <path to binary> <path to profile filename>

With graphviz installed and in the path, a call graph can be generated with:

go tool pprof -svg <path to binary> <path to profile filename> > <output svg file>
