package fuse

import "github.com/GoogleCloudPlatform/cloudsql-proxy/proxy/fuse"

Package fuse provides a connection source wherein the user does not need to specify which instance they are connecting to before they start the executable. Instead, simply attempting to access a file in the provided directory will transparently create a proxied connection to an instance which has that name.

Specifically, given that NewConnSrc was called with the mounting directory as /cloudsql:

1. Execute `mysql -S /cloudsql/speckle:instance`
2. The 'mysql' executable looks up the file "speckle:instance" inside "/cloudsql"
3. This lookup is intercepted by the code in this package. A local unix socket located in a temporary directory is opened for listening and the lookup for "speckle:instance" returns to mysql saying that it is a symbolic link pointing to this new local socket.
4. mysql dials the local unix socket, creating a new connection to the specified instance.

Functions ¶

func NewConnSrc ¶

func NewConnSrc(mountdir, tmpdir string, client *proxy.Client, connset *proxy.ConnSet) (<-chan proxy.Conn, io.Closer, error)

NewConnSrc returns a source of new connections based on Lookups in the provided mount directory. If there isn't a directory located at tmpdir one is created. The second return parameter can be used to shutdown and release any resources. As a result of this shutdown, or during any other fatal error, the returned chan will be closed.

The connset parameter is optional.

func Supported ¶

func Supported() bool

Supported returns true if the current system supports FUSE.
