|
Summary: Windows native build script. This is similar to functionality provided
|
|
by hack\make.sh, but uses native Windows PowerShell semantics. It does
|
|
not support the full set of options provided by the Linux counterpart.
|
|
For example:
|
|
|
|
- You can't cross-build Linux docker binaries on Windows
|
|
- Hashes aren't generated on binaries
|
|
- 'Releasing' isn't supported.
|
|
- Integration tests. This is because they currently cannot run inside a container,
|
|
and require significant external setup.
|
|
|
|
It does however provided the minimum necessary to support parts of local Windows
|
|
development and Windows to Windows CI.
|
|
|
|
Usage Examples (run from repo root):
|
|
"hack\make.ps1 -Binary" to build the binaries
|
|
"hack\make.ps1 -Client" to build just the client 64-bit binary
|
|
"hack\make.ps1 -TestUnit" to run unit tests
|
|
"hack\make.ps1 -Binary -TestUnit" to build the binaries and run unit tests
|
|
"hack\make.ps1 -All" to run everything this script knows about
|
|
|
|
.PARAMETER Client
|
|
Builds the client binaries.
|
|
|
|
.PARAMETER Daemon
|
|
Builds the daemon binary.
|
|
|
|
.PARAMETER Binary
|
|
Builds the client binaries and the daemon binary. A convenient shortcut to `make.ps1 -Client -Daemon`.
|
|
|
|
.PARAMETER Race
|
|
Use -race in go build and go test.
|
|
|
|
.PARAMETER Noisy
|
|
Use -v in go build.
|
|
|
|
.PARAMETER ForceBuildAll
|
|
Use -a in go build.
|
|
|
|
.PARAMETER NoOpt
|
|
Use -gcflags -N -l in go build to disable optimisation (can aide debugging).
|
|
|
|
.PARAMETER CommitSuffix
|
|
Adds a custom string to be appended to the commit ID (spaces are stripped).
|
|
|
|
.PARAMETER DCO
|
|
Runs the DCO (Developer Certificate Of Origin) test.
|
|
|
|
.PARAMETER PkgImports
|
|
Runs the pkg\ directory imports test.
|
|
|
|
.PARAMETER GoFormat
|
|
Runs the Go formatting test.
|
|
|
|
.PARAMETER TestUnit
|
|
Runs unit tests.
|
|
|
|
.PARAMETER All
|
|
Runs everything this script knows about.
|
|
|
|
|
|
TODO
|
|
- Unify the head commit
|
|
- Sort out the GITCOMMIT environment variable in the absense of a .git (longer term)
|
|
- Add golint and other checks (swagger maybe?)
