Functions

func GetGitalyProcessTempDir 

func GetGitalyProcessTempDir(parentDir string, processID int) string

GetGitalyProcessTempDir constructs a temporary directory name for the current gitaly process. This way, we can clean up old temporary directories by inspecting the pid attached to the folder.

func NewLocator 

func NewLocator(conf Cfg) storage.Locator

NewLocator returns locator based on the provided configuration struct. As it creates a shallow copy of the provided struct changes made into provided struct may affect result of methods implemented by it.

func PruneOldGitalyProcessDirectories 

func PruneOldGitalyProcessDirectories(log log.FieldLogger, directory string) error

PruneOldGitalyProcessDirectories removes leftover temporary directories that belonged to processes that no longer exist. Directories are expected to be in the form gitaly-<pid>. The removals are logged prior to being executed. Unexpected directory entries are logged but not removed.

func SetupRuntimeDirectory 

func SetupRuntimeDirectory(cfg Cfg, processID int) (string, error)

SetupRuntimeDirectory creates a new runtime directory. Runtime directory contains internal runtime data generated by Gitaly such as the internal sockets. If cfg.RuntimeDir is set, it's used as the parent directory for the runtime directory. Runtime directory owner process can be identified by the suffix process ID suffixed in the directory name. If a directory already exists for this process' ID, it's removed and recreated. If cfg.RuntimeDir is not set, a temporary directory is used instead. A directory is created for the internal socket as well since it is expected to be present in the runtime directory. SetupRuntimeDirectory returns the absolute path to the created runtime directory.

Types

type Cfg 

type Cfg struct {
	// ConfigCommand specifies the path to an executable that Gitaly will run after loading the
	// initial configuration from disk. The executable is expected to write JSON-formatted
	// configuration to its standard output that we will then deserialize and merge back into
	// the initially-loaded configuration again. This is an easy mechanism to generate parts of
	// the configuration at runtime, like for example secrets.
