Download from cloud, if necessary

Meant for internal use, as there are internal objects as arguments.

cloudDownload(
  outputHash,
  newFileName,
  gdriveLs,
  cachePath,
  cloudFolderID,
  drv = getDrv(getOption("reproducible.drv", NULL)),
  conn = getOption("reproducible.conn", NULL),
  verbose = getOption("reproducible.verbose")
)

Arguments

outputHash

The cacheId of the object to upload

newFileName

The character string of the local filename that the downloaded object will have

gdriveLs

The result of googledrive::drive_ls(googledrive::as_id(cloudFolderID), pattern = "outputHash")

cachePath

A repository used for storing cached objects. This is optional if Cache is used inside a SpaDES module.

cloudFolderID

A googledrive dribble of a folder, e.g., using drive_mkdir(). If left as NULL, the function will create a cloud folder with name from last two folder levels of the cachePath path, : paste0(basename(dirname(cachePath)), "_", basename(cachePath)). This cloudFolderID will be added to options("reproducible.cloudFolderID"), but this will not persist across sessions. If this is a character string, it will treat this as a folder name to create or use on GoogleDrive.

drv

if using a database backend, drv must be an object that inherits from DBIDriver e.g., from package RSQLite, e.g., SQLite

conn

an optional DBIConnection object, as returned by dbConnect().

verbose

Numeric, -1 silent (where possible), 0 being very quiet, 1 showing more messaging, 2 being more messaging, etc. Default is 1. Above 3 will output much more information about the internals of Caching, which may help diagnose Caching challenges. Can set globally with an option, e.g., options('reproducible.verbose' = 0) to reduce to minimal
