func AddNewAssertionForTest 

func AddNewAssertionForTest(
	config Config, oldAssertion, newAssertion string) error

AddNewAssertionForTest makes newAssertion, which should be a single assertion that doesn't already resolve to anything, resolve to the same UID as oldAssertion, which should be an arbitrary assertion that does already resolve to something. It only applies to the given config.

func AddNewAssertionForTestOrBust 

func AddNewAssertionForTestOrBust(t logger.TestLogBackend, config Config,
	oldAssertion, newAssertion string)

AddNewAssertionForTestOrBust is like AddNewAssertionForTest, but dies if there's an error.

func BackgroundContextWithCancellationDelayer 

func BackgroundContextWithCancellationDelayer() context.Context

func BoolForString 

func BoolForString(s string) bool

BoolForString returns false if trimmed string is "" (empty), "0", "false", or "no"

func BuildCanonicalPath 

func BuildCanonicalPath(pathType PathType, paths ...string) string

BuildCanonicalPath returns a canonical path for a path components. This a canonical path and may need to be converted to a platform specific path, for example, on Windows, this might correspond to k:\private\username.

func CheckConfigAndShutdown 

func CheckConfigAndShutdown(
	ctx context.Context, t logger.TestLogBackend, config Config)

CheckConfigAndShutdown shuts down the given config, but fails the test if there's an error.

func CheckTlfHandleOffline 

func CheckTlfHandleOffline(
	ctx context.Context, name string, public bool) error

CheckTlfHandleOffline does light checks whether a TLF handle looks ok, it avoids all network calls.

func CleanupCancellationDelayer 

func CleanupCancellationDelayer(ctx context.Context) error

CleanupCancellationDelayer cleans up a context (ctx) that is cancellation delayable and makes the go routine spawned in NewContextWithCancellationDelayer exit. As part of the cleanup, this also causes the cancellation delayable context to be canceled, no matter whether the timeout passed into the EnableDelayedCancellationWithGracePeriod has passed or not.

Ideally, the parent ctx's cancelFunc is always called upon completion of handling a request, in which case this wouldn't be necessary.

func ConvertIdentifyError 

func ConvertIdentifyError(assertion string, err error) error

ConvertIdentifyError converts a errors during identify into KBFS errors

func DisableCRForTesting 

func DisableCRForTesting(config Config, folderBranch FolderBranch) error

DisableCRForTesting stops conflict resolution for the given folder. RestartCRForTesting should be called to restart it.

DumpPrivateMetadata returns a detailed dump of the given PrivateMetadata's contents.

func EnableDelayedCancellationWithGracePeriod 

func EnableDelayedCancellationWithGracePeriod(ctx context.Context, timeout time.Duration) error

EnableDelayedCancellationWithGracePeriod can be called on a "cancellation delayable" context produced by NewContextWithCancellationDelayer, to enable delayed cancellation for ctx. This is useful to indicate that the operation(s) associated with the context has entered a critical state, and it should not be canceled until after timeout or CleanupCancellationDelayer is called.

Note that if EnableDelayedCancellationWithGracePeriod is called for the second time, and the grace period has started due to a cancellation, the grace period would not be extended (i.e. timeout has no effect in this case). Although in this case, no error is returned, since the delayed cancellation is already enabled.

func EncodeRootMetadataSigned 

func EncodeRootMetadataSigned(
	codec kbfscodec.Codec, rmds *RootMetadataSigned) ([]byte, error)

EncodeRootMetadataSigned serializes a metadata block. This should be used instead of directly calling codec.Encode(), as it handles some version-specific quirks.

func NewContextReplayable 

func NewContextReplayable(
	ctx context.Context, change CtxReplayFunc) context.Context

NewContextReplayable creates a new context from ctx, with change applied. It also makes this change replayable by NewContextWithReplayFrom. When replayed, the resulting context is replayable as well.

It is important that all WithValue-ish mutations on ctx is done "replayably" (with NewContextReplayable) if any delayed cancellation is used, e.g. through EnableDelayedCancellationWithGracePeriod,

func NewContextWithCancellationDelayer 

func NewContextWithCancellationDelayer(
	ctx context.Context) (newCtx context.Context, err error)

NewContextWithCancellationDelayer creates a new context out of ctx. All replay functions attached to ctx are run on the new context. In addition, the new context is made "cancellation delayable". That is, it disconnects the cancelFunc from ctx, and watch for the cancellation. When cancellation happens, it checks if delayed cancellation is enabled for the associated context. If so, it waits until it's disabled before cancelling the new context. This provides a hacky way to allow finer control over cancellation.

Note that, it's important to call context.WithCancel (or its friends) before this function if those cancellations need to be controllable ("cancellation delayable"). Otherwise, the new cancelFunc is inherently NOT ("cancellation delayable").

If this function is called, it is caller's responsibility to either 1) cancel ctx (the context passed in); or 2) call CleanupCancellationDelayer; when operations associated with the context is done. Otherwise it leaks go routines!

func NewContextWithReplayFrom 

func NewContextWithReplayFrom(ctx context.Context) (context.Context, error)

NewContextWithReplayFrom constructs a new context out of ctx by calling all attached replay functions. This disconnects any existing context.CancelFunc.

BlockCacheLifetime denotes the lifetime of an entry in BlockCache. 

const (
	// NoCacheEntry means that the entry will not be cached.
	NoCacheEntry BlockCacheLifetime = iota
	// TransientEntry means that the cache entry may be evicted at
	// any time.
	TransientEntry
	// PermanentEntry means that the cache entry must remain until
	// explicitly removed from the cache.
	PermanentEntry
)

type BlockCacheSimple 

type BlockCacheSimple interface {
	// Get gets the block associated with the given block ID.
	Get(ptr BlockPointer) (Block, error)
	// Put stores the final (content-addressable) block associated
	// with the given block ID. If lifetime is TransientEntry,
	// then it is assumed that the block exists on the server and
	// the entry may be evicted from the cache at any time. If
	// lifetime is PermanentEntry, then it is assumed that the
	// block doesn't exist on the server and must remain in the
	// cache until explicitly removed. As an intermediary state,
	// as when a block is being sent to the server, the block may
	// be put into the cache both with TransientEntry and
	// PermanentEntry -- these are two separate entries. This is
	// fine, since the block should be the same.
	Put(ptr BlockPointer, tlf tlf.ID, block Block,
		lifetime BlockCacheLifetime) error
}

BlockCacheSimple gets and puts plaintext dir blocks and file blocks into a cache. These blocks are immutable and identified by their content hash.

type BlockCacheStandard 

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

BlockCacheStandard implements the BlockCache interface by storing blocks in an in-memory LRU cache. Clean blocks are identified internally by just their block ID (since blocks are immutable and content-addressable).

func NewBlockCacheStandard 

func NewBlockCacheStandard(transientCapacity int,
	cleanBytesCapacity uint64) *BlockCacheStandard

NewBlockCacheStandard constructs a new BlockCacheStandard instance with the given transient capacity (in number of entries) and the clean bytes capacity, which is the total of number of bytes allowed between the transient and permanent clean caches. If putting a block will exceed this bytes capacity, transient entries are evicted until the block will fit in capacity.

	ptr BlockPointer, tlf tlf.ID, block Block, lifetime BlockCacheLifetime,
	hasPrefetched bool) (err error)

PutWithPrefetch implements the BlockCache interface for BlockCacheStandard. This method is idempotent for a given ptr, but that invariant is not currently goroutine-safe, and it does not hold if a block size changes between Puts. That is, we assume that a cached block associated with a given pointer will never change its size, even when it gets Put into the cache again.

func (*BlockCacheStandard) SetCleanBytesCapacity 

func (b *BlockCacheStandard) SetCleanBytesCapacity(capacity uint64)

SetCleanBytesCapacity implements the BlockCache interface for BlockCacheStandard.

type BlockChanges

	Info BlockInfo `codec:"p,omitempty"`
	// An ordered list of operations completed in this update
	Ops opsList `codec:"o,omitempty"`
	// contains filtered or unexported fields
}

BlockChanges tracks the set of blocks that changed in a commit, and the operations that made the changes. It might consist of just a BlockPointer if the list is too big to embed in the MD structure directly.

If this commit represents a conflict-resolution merge, which may comprise multiple individual operations, then there will be an ordered list of the changes for individual operations. This lets the notification and conflict resolution strategies figure out the difference between a renamed file and a modified file, for example.

	// DirectBlock indicates the pointed-to block has no indirect
	// pointers.
	DirectBlock BlockDirectType = 1
	// IndirectBlock indicates the pointed-to block has indirect
	// pointers.
	IndirectBlock BlockDirectType = 2
)

	// the block.
	EncodedSize uint32 `codec:"e"`
}

	// write-through cache once a Get completes.
	Get(ctx context.Context, kmd KeyMetadata, blockPtr BlockPointer,
		block Block, cacheLifetime BlockCacheLifetime) error

	// Ready turns the given block (which belongs to the TLF with

	// and calculates its ID and size, so that we can do a bunch
	// of block puts in parallel for every write. Ready() must
	// guarantee that plainSize <= readyBlockData.QuotaSize().
	Ready(ctx context.Context, kmd KeyMetadata, block Block) (
		id kbfsblock.ID, plainSize int, readyBlockData ReadyBlockData, err error)

	// Delete instructs the server to delete the given block references.
	// It returns the number of not-yet deleted references to
	// each block reference
	Delete(ctx context.Context, tlfID tlf.ID, ptrs []BlockPointer) (
		liveCounts map[kbfsblock.ID]int, err error)

	// Archive instructs the server to mark the given block references
	// as "archived"; that is, they are not being used in the current
	// view of the folder, and shouldn't be served to anyone other
	// than folder writers.
	Archive(ctx context.Context, tlfID tlf.ID, ptrs []BlockPointer) error

	// TogglePrefetcher activates or deactivates the prefetcher.
	TogglePrefetcher(ctx context.Context, enable bool) error

	// Prefetcher retrieves this BlockOps' Prefetcher.
	Prefetcher() Prefetcher

type DataVer 

type DataVer int

DataVer is the type of a version for marshalled KBFS data structures.

1) DataVer is a per-block attribute, not per-file. This means that, in theory, an indirect block with DataVer n may point to blocks with DataVers less than, equal to, or greater than n. However, for now, it's guaranteed that an indirect block will never point to blocks with greater versions than itself. (See #3 for details.)

2) DataVer is an external attribute of a block, meaning that it's not stored as part of the block, but computed by the creator (or anyone with the latest kbfs client), and stored only in pointers to the block.

2.5) A file (or, in the future a dir) can in theory have any arbitrary tree structure of blocks. However, we only write files such that all paths to leaves have the same depth.

Currently, in addition to 2.5, we have the following constraints on block tree structures: a) Direct blocks are always v1. b) Indirect blocks of depth 2 (meaning one indirect block pointing to all direct blocks) can be v1 (if it has no holes) or v2 (if it has holes). However, all its indirect pointers will have DataVer 1, by a). c) Indirect blocks of depth 3 must be v3 and must have at least one indirect pointer with an indirect DirectType [although if it holds for one, it should hold for all], although its indirect pointers may have any combination of DataVer 1 or 2, by b). d) Indirect blocks of dept k > 3 must be v3 and must have at least one indirect pointer with an indirect DirectType [although if it holds for one, it should hold for all], and all of its indirect pointers must have DataVer 3, by c). 

const (
	// FirstValidDataVer is the first value that is considered a
	// valid data version. Note that the nil value is not
	// considered valid.
	FirstValidDataVer DataVer = 1
	// ChildHolesDataVer is the data version for any indirect block
	// containing a set of pointers with holes.
	ChildHolesDataVer DataVer = 2
	// AtLeastTwoLevelsOfChildrenDataVer is the data version for
	// blocks that have multiple levels of indirection below them
	// (i.e., indirect blocks that point to other indirect blocks).
	AtLeastTwoLevelsOfChildrenDataVer DataVer = 3

}

DirtyBlockCache gets and puts plaintext dir blocks and file blocks into a cache, which have been modified by the application and not yet committed on the KBFS servers. They are identified by a (potentially random) ID that may not have any relationship with their context, along with a Branch in case the same TLF is being modified via multiple branches. Dirty blocks are never evicted, they must be deleted explicitly.

type DirtyBlockCacheStandard 

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

DirtyBlockCacheStandard implements the DirtyBlockCache interface by storing blocks in an in-memory cache. Dirty blocks are identified by their block ID, branch name, and reference nonce, since the same block may be forked and modified on different branches and under different references simultaneously.

DirtyBlockCacheStandard controls how fast uses can write into KBFS, and does so with a TCP-like slow-start algorithm that adjusts itself according to how fast bytes are synced to the server. Conceptually, there are two buffers: 

syncBuf: The bytes that are currently syncing, or have finished
syncing, back to the servers.  Each TLF has only one sync at a
time, but multiple TLFs may be syncing at the same time.  We also
track how many bytes within this buffer have finished syncing.

waitBuf: The bytes that have not yet begun syncing to the
servers.  Again, this can be for multiple TLFs, and from multiple
files within a TLF.  In the TCP analogy, think of this as the
congestion window (cwnd).

The goal is to make sure that syncBuf can always be transmitted to the server within the file system operation timeout forced on us by the layer that interacts with the file system (19 seconds on OS X and Windows, defaults to 30 seconds for other layers if not already set). In fact, ideally the data would be transmitted in HALF of the file system operation timeout, in case a user Sync operation gets blocked behind a background Sync operation when there is significant data in waitBuf. At the same time, we want it to be as big as possible, because we get the best performance when writing lots of blocks in parallel to the servers. So, we want an algorithm that allows waitBuf to grow, without causing the next sync (or write, or setattr, etc) operation to timeout. For the purposes of this discussion, let's assume there is only one active TLF at a time.

We allow the user to set a min, start, and max size for waitBuf. Whenever a sync starts, bytes are transferred from waitBuf into syncBuf and a timer is started. When a sync completes successfully, the number of bytes synced is added to the allowed size of waitBuf (i.e., "additive increase" == exponential growth). However, if the number of sync'd bytes is smaller than the min waitBuf size, we don't do additive increase (because we haven't really tested the throughput of the server connection in that case).

If the sync takes more than 33% of half the overall operation timeout, the size of waitBuf is reduced by that same percentage (i.e., "multiplicative decrease"), and any outstanding bytes in the sync will not be used in the "additive increase" phase when the sync completes (they are considered "lost" in the TCP analogy, even though they should eventually succeed). The 33% limit was chosen mostly by trial and error, although if you assume that capacity(waitBuf) will double after each sync, then `2*len(syncBuf) == capacity(waitBuf)`, so at any given point there can be about 3*capacity(syncBuf) bytes buffered; so if syncBuf can't be sync'd in a third of the overall timeout, the next waitBuf should be reduced.

Finally, we need to make sure that the Write calls that are filling up waitBuf while a sync is happening don't timeout. But, we also need to fill waitBuf quickly, so that the next sync is ready to go as soon as the first one completes. Here we implement a compromise. Allow waitBuf to fill up instantly until it holds capacity(syncBuf) bytes. After that, allow it to fill up to 2*capacity(syncBuf), but artificially delay each write by adding backpressure, by some fraction of the system operation timeout that matches the fraction of the progress the buffer has made between capacity(syncBuf) and 2*capacity(syncBuf). As soon as the sync completes, any delayed write is unblocked and gets to start filling up the buffers again.

To avoid keeping the buffer capacity large when network conditions suddenly worsen (say after a laptop sleep when it comes back online on a new, worse network), the capacity is reset back to the minimum if resetBufferCapTime passes without any large syncs. TODO: in the future it might make sense to decrease the buffer capacity, rather than resetting it to the minimum?

type ImmutableBareRootMetadata 

type ImmutableBareRootMetadata struct {
	BareRootMetadata
	// contains filtered or unexported fields
}

ImmutableBareRootMetadata is a thin wrapper around a BareRootMetadata and an ExtraMetadata that takes ownership of it and does not ever modify it again. Thus, its MdID can be calculated and stored along with a local timestamp. ImmutableBareRootMetadata objects can be assumed to never alias a (modifiable) BareRootMetadata.

Note that crypto.MakeMdID() on an ImmutableBareRootMetadata will compute the wrong result, since anonymous fields of interface type are not encoded inline by the codec. Use crypto.MakeMDID(ibrmd.BareRootMetadata) instead.

TODO: Move this to bare_root_metadata.go if it's used in more places.

JournalServer is the server that handles write journals. It interposes itself in front of BlockServer and MDOps. It uses MDOps instead of MDServer because it has to potentially modify the RootMetadata passed in, and by the time it hits MDServer it's already too late. However, this assumes that all MD ops go through MDOps.

The maximum number of characters added to the root dir by a journal server journal is 108: 51 for the TLF journal, and 57 for everything else.

KBFSOps handles all file system operations. Expands all indirect pointers. Operations that modify the server data change all the block IDs along the path, and so must return a path with the new BlockIds so the caller can update their references.

KBFSOps implementations must guarantee goroutine-safety of calls on a per-top-level-folder basis.

There are two types of operations that could block:

  • remote-sync operations, that need to synchronously update the MD for the corresponding top-level folder. When these operations return successfully, they will have guaranteed to have successfully written the modification to the KBFS servers.
  • remote-access operations, that don't sync any modifications to KBFS servers, but may block on reading data from the servers.

KBFSOps implementations are supposed to give git-like consistency semantics for modification operations; they will be visible to other clients immediately after the remote-sync operations succeed, if and only if there was no other intervening modification to the same folder. If not, the change will be sync'd to the server in a special per-device "unmerged" area before the operation succeeds. In this case, the modification will not be visible to other clients until the KBFS code on this device performs automatic conflict resolution in the background.

All methods take a Context (see https://blog.golang.org/context), and if that context is cancelled during the operation, KBFSOps will abort any blocking calls and return ctx.Err(). Any notifications resulting from an operation will also include this ctx (or a Context derived from it), allowing the caller to determine whether the notification is a result of their own action or an external action.

type KBFSOpsStandard

	// still continue to work, but new lookups on the old name may
	// either encounter alias errors or entirely new TLFs (in the case
	// of conflicts).
	TlfHandleChange(ctx context.Context, newHandle *TlfHandle)
}
