Could be improved in the future to return different codes depending on its status (e.g. doesn't exist = 404, 102 for loading, 500 for error, etc), but 404 makes the most sense until that has been developed
- If an identifier parameter is missing or empty, it will return an unfiltered list of all possible identifiers.
- If an identifier is specified, only resources with a matching identifier will be returned.
- If default is set to true, only resources without identifiers will be returned.
Files are now keyed by signature, in the format:
data/si/gn/signature/hash
For times when there is no signature available (i.e. at the time of initial upload), files are keyed by hash, in the format:
data/_misc/ha/sh/hash
Files in the _misc folder are subsequently relocated to a path that is keyed by the resulting signature.
The end result is that chunks are now grouped on the filesystem by signature. This allows more transparency as to what is being hosted, and will also help simplify the reporting and management of local files.
This should allow for a relatively even distribution of chunks, but there is a (currently unavoidable) risk of files with very few mirrors being deleted altogether.
Longer term this could be improved by checking that one of our peers has a file, before it's deleted locally
Nodes will stop proactively storing new data when they reach 90% capacity.
A new "maxStorageCapacity" setting has been added to allow the user to optionally limit the allocated space for this node. Limits are approximate only, not exact.
publicDataEnabled - whether to store decryptable data (default true)
privateDataEnabled - whether to store data without a decryption key (default false)
This doesn't affect minting rewards; it is simply a means of reducing block candidates. There should be no noticeable difference other than hopefully less re-orgs. We can ultimately do a hard fork and increase Blockchain.minAccountLevelToMint but this allows us to test the approach in a lower risk way.
The missing data check was triggering decryptions, extractions, etc. Replaced with some code which checks for the presence of chunks on the local machine, without getting involved with any build process overhead.
- "NOT_STARTED" is now "DOWNLOADED"
- "DOWNLOADING" is now "MISSING_DATA"
- Removed "DOWNLOAD_FAILED"
Some of these could be reintroduced once the system is able to support them.
These can be used to check the current status of a resource. The different statuses are:
NOT_STARTED,
DOWNLOADING
DOWNLOADED
BUILDING
READY
DOWNLOAD_FAILED
BUILD_FAILED
UNSUPPORTED
Not all statuses are returned yet. The build process needs more functionality to be able to support DOWNLOADED and DOWNLOAD_FAILED. Also, BUILDING and BUILD_FAILED are currently unable to distinguish between different resources with the same registered name, so need some attention.
