type Cache ¶

type Cache struct {
	// contains filtered or unexported fields
}

Cache persists the files for template versions, and is used by dynamic parameters to deduplicate the files in memory. When any number of users opens the workspace creation form for a given template version, it's files are loaded into memory exactly once. We hold those files until there are no longer any open connections, and then we remove the value from the map.

func New(registerer prometheus.Registerer, authz rbac.Authorizer) *Cache

func (c *Cache) Acquire(ctx context.Context, db database.Store, fileID uuid.UUID) (*CloseFS, error)

func (c *Cache) Count() int

type CacheCloser ¶ added in v2.24.0

type CacheCloser struct {
	// contains filtered or unexported fields
}

CacheCloser is a cache wrapper used to close all acquired files. This is a more simple interface to use if opening multiple files at once.

func NewCacheCloser(cache FileAcquirer) *CacheCloser

func (c *CacheCloser) Acquire(ctx context.Context, db database.Store, fileID uuid.UUID) (*CloseFS, error)

func (c *CacheCloser) Close()

type CacheEntryValue ¶ added in v2.24.0

type CacheEntryValue struct {
	fs.FS
	Object rbac.Object
	Size   int64
}

type CloseFS ¶ added in v2.24.0

type CloseFS struct {
	fs.FS
	// contains filtered or unexported fields
}

CloseFS is a wrapper around fs.FS that implements io.Closer. The Close() method tells the cache to release the fileID. Once all open references are closed, the file is removed from the cache.

func (f *CloseFS) Close()

type FileAcquirer ¶ added in v2.24.0

type FileAcquirer interface {
	Acquire(ctx context.Context, db database.Store, fileID uuid.UUID) (*CloseFS, error)
}

type Overlay ¶ added in v2.23.0

type Overlay struct {
	Path string
	fs.FS
}
