type FolderCreationTracker 

type FolderCreationTracker interface {
	RecordCreation(folder string)
	ShouldSetProperties(folder string, overwrite OverwriteOption, prompter Prompter) bool
	StopTracking(folder string)
}

folderCreationTracker is used to ensure than in an overwrite=false situation we only set folder properties on folders which were created by the current job. (To be consistent with the fact that when overwrite == false, we only set file properties on files created by the current job)

type FolderDeletionFunc 

type FolderDeletionFunc func(context.Context, ILogger) bool

folderDeletionFunc should delete the folder IF IT IS EMPTY, and return true. If it is not empty, false must be returned. FolderDeletionManager is allowed to call this on a folder that is not yet empty. In that case, FolderDeletionManager may call it again later. Errors are not returned because of the delay to when deletion might happen, so it's up to the func to do its own logging

type FolderDeletionManager 

type FolderDeletionManager interface {

	// RecordChildExists takes a child name and counts it against the child's immediate parent
	// Should be called for both types of child: folders and files.
	// Only counts it against the immediate parent (that's all that's necessary, because we recurse in tryDeletion)
	RecordChildExists(childFileOrFolder *url.URL)

	// RecordChildDelete records that a file, previously passed to RecordChildExists, has now been deleted
	// Only call for files, not folders
	RecordChildDeleted(childFile *url.URL)

	// RequestDeletion registers a function that will be called to delete the given folder, when that
	// folder has no more known children.  May be called before, after or during the time that
	// the folder's children are being passed to RecordChildExists and RecordChildDeleted
	//
	// Warning: only pass in deletionFuncs that will do nothing and return FALSE if the
	// folder is not yet empty. If they return false, they may be called again later.
	RequestDeletion(folder *url.URL, deletionFunc FolderDeletionFunc)
}

FolderDeletionManager handles the fact that (in most locations) we can't delete folders that still contain files. So it allows us to request deletion of a folder, and have that be attempted after the last file is removed. Note that maybe the apparent last file isn't the last (e.g. there are other files, still to be deleted, in future job parts), in which case any failed deletion will be retried if there's a new "candidate last child" removed. Takes URLs rather than strings because that ensures correct (un)escaping, and makes it clear that we don't support Windows & MacOS local paths (which have cases insensitivity that we don't support here).

func NewFolderDeletionManager(ctx context.Context, fpo FolderPropertyOption, logger ILogger) FolderDeletionManager

This isn't an overarching, perfect implementation.

Example, given invalid metadata for Azure: '123-invalid':'content', it will be resolved as two new k:v pairs: 'rename_123_invalid':'content' 'rename_key_123_invalid':'123-invalid' So user can try to recover the metadata in Azure side. Note: To keep first version simple, whenever collision is found during key resolving, error will be returned. This can be further improved once any user feedback get.

	// BlockingPrefetch tries to read the full contents of the chunk into RAM.
	BlockingPrefetch(fileReader io.ReaderAt, isRetry bool) error

	// GetPrologueState is used to grab enough of the initial bytes to do MIME-type detection.  Expected to be called only
	// on the first chunk in each file (since there's no point in calling it on others)
	// There is deliberately no error return value from the Prologue.
	// If it failed, the Prologue itself must call jptm.FailActiveSend.
	GetPrologueState() PrologueState

	// Length is the number of bytes in the chunk
	Length() int64

	// HasPrefectchedEntirelyZeros gives an indication of whether this chunk is entirely zeros.  If it returns true
	// then the chunk content has been prefetched AND it was all zeroes. For some remote destinations, that support "sparse file"
	// semantics, it is safe and correct to skip the upload of those chunks where this returns true.
	// In the rare edge case where this returns false due to the prefetch having failed (rather than the contents being non-zero),
	// we'll just treat it as a non-zero chunk. That's simpler (to code, to review and to test) than having this code force a prefetch.
	HasPrefetchedEntirelyZeros() bool

	// WriteBufferTo writes the entire contents of the prefetched buffer to h
	// Panics if the internal buffer has not been prefetched (or if its been discarded after a complete Read)
	WriteBufferTo(h hash.Hash)
}

Reader of ONE chunk of a file. Maybe used to re-read multiple times (e.g. if we must retry the sending of the chunk). A instance of this type cannot be used by multiple threads (since it's Read/Seek are inherently stateful) The reader can throw away the data after each successful read, and then re-read it from disk if there is a need to retry the transmission of the chunk. That saves us the RAM cost of from having to keep every transmitted chunk in RAM until acknowledged by the service. We just re-read if the service says we need to retry. Although there's a time (performance) cost in the re-read, that's fine in a retry situation because the retry indicates we were going too fast for the service anyway.
