Rename to zh_SC for better distinguish between zh_SC (Simple Chinese)and zh_TC(Traditional Chinese)
Rephrase some of the words for better understanding.
This can be used to preview a site before signing a transaction and announcing it to the network. The response will need reworking to return JSON (along with most of the other new APIs)
This fixes an NPE when trying to send a file that doesn't exist. It also removes the caching, which we can add again later if it turns out to be needed.
Now that we aren't disconnecting mid sync, we can get away with more frequent disconnections. This brings the average connection length to around 9 mins.
Connection limits are defined in settings (denominated in seconds):
"minPeerConnectionTime": 120,
"maxPeerConnectionTime": 3600
Peers will disconnect after a randomly chosen amount of time between the min and the max. The default range is 2 minutes to 1 hour, as above.
This encourages nodes to connect to a wider range of peers across the course of each day, rather than staying connected to an "island" of peers for an extended period of time. Hopefully this will reduce the amount of parallel chains that can form due to permanently connected clusters of peers.
We may find that we need to reduce the defaults to get optimal results, however it is best to do this incrementally, with the option for reducing further via each node's settings. Being too aggressive here could cause some of the earlier problems (e.g. 20% missing blocks minted) to reappear. We can re-evaluate this in the next version. Note that if defaults are reduced significantly, we may need to add code to prevent this from happening mid-sync. With higher defaults, this is less of an issue.
Thanks to @szisti for supplying some base code for this commit, and also to @CWDSYSTEMS for diagnosing the original problem.
This indicates the size of the re-org/rollback that was required in order to perform this sync operation. It is only included if it's greater than 0 blocks.
This deletes a file referenced by a user supplied SHA256 digest string (which we will use as the file's "ID" in the Qortal data system). In the future this could be extended to delete all associated chunks, but first we need to build out the data chain so we have a way to look up chunks associated with a file hash.
