The FineFundamentalSubscriptionEnumeratorFactory used in combination with SingleEntryDataCacheProvider and DefaultDataProvider was never disposing of the underlying file stream, leaving files open.
Instead of leaving zip exceptions to the data feed enumerator stack, we now log file names of corrupt zip files, return null and continue.
The file system data feed should now handle corrupt files like missing files.
Refactored IDataProvider interface to return stream. The IDataProvider
Fetch method now only takes a key. The IDataProvider
has been reshuffled to be at the bottom of the LeanDataStack. It provides
data to the rest of the Lean stack. The default implementation of IDataProvider reads
data from disc.
All IDataCacheProviders now have constructors which take IDataProviders
and use them to find data on disc.
Renamed DataCacheProvider to ZipDataCacheProvider
Added comments to IDataProvider and it's implementations
