Overview

Package views provides high-level clients for talking to the main data tree in certain context.

It follows the "wrapper" pattern of http handlers to filter all requests inputs and outputs. The "Router" is object is used by all services or gateways when accessing to data as a given user. Between others, it will - Load ACLs and perform checks to make sure user is allowed to read/write the data - Perform other meta-related or acl-related checks like Quota management, locks, etc.. - Perform encryption/decryption of actual data on the fly - Compress / Decompress archives, - Add metadata collected from any services on the nodes outputted by the responses, - etc...

}

VersionHandler capture ListNodes and GetObject calls to find existing nodes versions and retrieve them.

func (*VersionHandler) CopyObject 

func (v *VersionHandler) CopyObject(ctx context.Context, from *tree.Node, to *tree.Node, requestData *CopyRequestData) (int64, error)

CopyObject intercept request with a SrcVersionId to read original from Version Store

func (*VersionHandler) GetObject 

func (v *VersionHandler) GetObject(ctx context.Context, node *tree.Node, requestData *GetRequestData) (io.ReadCloser, error)

GetObject redirects to Version Store if request contains a VersionID

func (*VersionHandler) ListNodes 

func (v *VersionHandler) ListNodes(ctx context.Context, in *tree.ListNodesRequest, opts ...client.CallOption) (tree.NodeProvider_ListNodesClient, error)

Create list of nodes if the Versions are required

func (*VersionHandler) ReadNode 

func (v *VersionHandler) ReadNode(ctx context.Context, req *tree.ReadNodeRequest, opts ...client.CallOption) (*tree.ReadNodeResponse, error)

type VirtualNodesBrowser 

type VirtualNodesBrowser struct {
	AbstractHandler
}

VirtualNodesBrowser is used by admin mode to list virtual nodes instead of their resolved values.

func NewVirtualNodesBrowser 

func NewVirtualNodesBrowser() *VirtualNodesBrowser

func (*VirtualNodesBrowser) ListNodes 

func (v *VirtualNodesBrowser) ListNodes(ctx context.Context, in *tree.ListNodesRequest, opts ...client.CallOption) (streamer tree.NodeProvider_ListNodesClient, e error)

ListNodes Append virtual nodes to the datasources list if admin is listing the root of the tree

func (*VirtualNodesBrowser) ReadNode 

func (v *VirtualNodesBrowser) ReadNode(ctx context.Context, in *tree.ReadNodeRequest, opts ...client.CallOption) (*tree.ReadNodeResponse, error)

ReadNode creates a fake node if admin is reading info about a virtual node

type VirtualNodesManager 

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

VirtualNodesManager keeps an internal list of virtual nodes. They are cached for one minute to avoid too many requests on docstore service.

func GetVirtualNodesManager 

func GetVirtualNodesManager() *VirtualNodesManager

GetVirtualNodesManager creates a new VirtualNodesManager.

func (*VirtualNodesManager) ByPath 

func (m *VirtualNodesManager) ByPath(path string) (*tree.Node, bool)

ByPath finds a VirtualNode by its Path.

func (*VirtualNodesManager) ByUuid 

func (m *VirtualNodesManager) ByUuid(uuid string) (*tree.Node, bool)

ByUuid finds a VirtualNode by its Uuid.

func (*VirtualNodesManager) GetResolver 

func (m *VirtualNodesManager) GetResolver(pool SourcesPool, createIfNotExists bool) func(context.Context, *tree.Node) (*tree.Node, bool)

GetResolver injects some dependencies to generate a simple resolver function

func (*VirtualNodesManager) ListNodes 

func (m *VirtualNodesManager) ListNodes() []*tree.Node

ListNodes simply returns the internally cached list.

func (*VirtualNodesManager) Load 

func (m *VirtualNodesManager) Load(forceReload ...bool)

Load requests the virtual nodes from the DocStore service.

func (*VirtualNodesManager) ResolveInContext 

func (m *VirtualNodesManager) ResolveInContext(ctx context.Context, vNode *tree.Node, clientsPool SourcesPool, create bool, retry ...bool) (*tree.Node, error)

ResolveInContext computes the actual node Path based on the resolution metadata of the virtual node and the current metadata contained in context.

type VirtualNodesResolver 

type VirtualNodesResolver struct {
	AbstractBranchFilter
}

VirtualNodesResolver dynamically resolves virtual nodes to their runtime value.

func NewVirtualNodesHandler 

func NewVirtualNodesHandler() *VirtualNodesResolver

type WalkFilter 

type WalkFilter func(ctx context.Context, node *tree.Node) bool

type WalkFunc 

type WalkFunc func(ctx context.Context, node *tree.Node, err error) error

type WorkspaceRootResolver 

type WorkspaceRootResolver struct {
	AbstractBranchFilter
}

WorkspaceRootResolver is an AbstractBranchFilter finding workspace root(s) based on the path.

func NewWorkspaceRootResolver 

func NewWorkspaceRootResolver() *WorkspaceRootResolver
