Functions

func AddFile

func AddFile(a Archive, file string) error

AddFile appends an existing file to an archive.

func AzureBlobstoreDelete

func AzureBlobstoreDelete(config AzureBlobstoreConfig, blobs []azblob.BlobItem) error

AzureBlobstoreDelete iterates over a list of files to delete and removes them from the blobstore.

func AzureBlobstoreList

func AzureBlobstoreList(config AzureBlobstoreConfig) ([]azblob.BlobItem, error)

AzureBlobstoreList lists all the files contained within an azure blobstore.

func AzureBlobstoreUpload

func AzureBlobstoreUpload(path string, name string, config AzureBlobstoreConfig) error

AzureBlobstoreUpload uploads a local file to the Azure Blob Storage. Note, this method assumes a max file size of 64MB (Azure limitation). Larger files will need a multi API call approach implemented.

See: https://msdn.microsoft.com/en-us/library/azure/dd179451.aspx#Anchor_3

func CopyFile

func CopyFile(dst, src string, mode os.FileMode)

CopyFile copies a file.

func ExpandPackagesNoVendor

func ExpandPackagesNoVendor(patterns []string) []string

ExpandPackagesNoVendor expands a cmd/go import path pattern, skipping vendored packages.

func GOPATH

func GOPATH() string

GOPATH returns the value that the GOPATH environment variable should be set to.

func GoTool

func GoTool(tool string, args ...string) *exec.Cmd

GoTool returns the command that runs a go tool. This uses go from GOROOT instead of PATH so that go commands executed by build use the same version of Go as the 'host' that runs build code. e.g.

/usr/lib/go-1.11/bin/go run build/ci.go ...

runs using go 1.11 and invokes go 1.11 tools from the same GOROOT. This is also important because runtime.Version checks on the host should match the tools that are run.

func MustRun

func MustRun(cmd *exec.Cmd)

MustRun executes the given command and exits the host process for any error.

func MustRunCommand

func MustRunCommand(cmd string, args ...string)

func PGPKeyID

func PGPKeyID(pgpkey string) (string, error)

PGPKeyID parses an armored key and returns the key ID.

func PGPSignFile

func PGPSignFile(input string, output string, pgpkey string) error

PGPSignFile parses a PGP private key from the specified string and creates a signature file into the output parameter of the input file.

Note, this method assumes a single key will be container in the pgpkey arg, furthermore that it is in armored format.

func Render

func Render(templateFile, outputFile string, outputPerm os.FileMode, x interface{})

Render renders the given template file into outputFile.

func RenderString

func RenderString(templateContent, outputFile string, outputPerm os.FileMode, x interface{})

RenderString renders the given template string into outputFile.

func RunGit

func RunGit(args ...string) string

RunGit runs a git subcommand and returns its output. The command must complete successfully.

func UploadSFTP

func UploadSFTP(identityFile, host, dir string, files []string) error

UploadSFTP uploads files to a remote host using the sftp command line tool. The destination host may be specified either as [user@]host[: or as a URI in the form sftp://[user@]host[:port].

func WriteArchive

func WriteArchive(name string, files []string) (err error)

WriteArchive creates an archive containing the given files.

Types

type Archive

type Archive interface {
	// Directory adds a new directory entry to the archive and sets the
	// directory for subsequent calls to Header.
	Directory(name string) error

	// Header adds a new file to the archive. The file is added to the directory
	// set by Directory. The content of the file must be written to the returned
	// writer.
	Header(os.FileInfo) (io.Writer, error)

	// Close flushes the archive and closes the underlying file.
	Close() error
}

func NewArchive

func NewArchive(file *os.File) (Archive, string)

func NewTarballArchive

func NewTarballArchive(w io.WriteCloser) Archive

func NewZipArchive

func NewZipArchive(w io.WriteCloser) Archive

type AzureBlobstoreConfig

type AzureBlobstoreConfig struct {
	Account   string // Account name to authorize API requests with
	Token     string // Access token for the above account
	Container string // Blob container to upload files into
}

AzureBlobstoreConfig is an authentication and configuration struct containing the data needed by the Azure SDK to interact with a speicifc container in the blobstore.

type Environment

type Environment struct {
	Name                string // name of the environment
	Repo                string // name of GitHub repo

	Buildnum            string
	IsPullRequest       bool
	IsCronJob           bool
}
