Error Codes

Proposal for consistent error codes across the entire lbrynet API.

Code	Name
1xx	Daemon start and other CLI command failures (non-recoverable)
10x	Meta error codes not presented by lbrynet itself but from apps trying to interact with lbrynet.
100	Cannot find the lbrynet command.
101	Permission denied trying to execute lbrynet command.
102	Executing lbrynet command does not produce any result.
103	Executing lbrynet produces a result that is not normal (eg. a segfault).
104	Failed to establish HTTP connection to lbrynet. (Is it running?)
105	HTTP connection established but daemon is not responding to commands.
106	Failed to establish WebSocket connection to lbrynet. (Is it running?)
107	WebSocket connection established but daemon is not responding to commands.
11x	Enough of lbrynet was able to start to determine external factors causing eventual failure.
110	Out of disk space.
111	Out of RAM.
12x	Internal factors preventing lbrynet from bootstrapping itself.
120	Incompatible version of Python.
121	Incompatible version of some library.
13x	Configuration errors.
130	Cannot write configuration file. (When writing the default config fails on startup, such as due to permission issues.)
131	Cannot find provided configuration file. (Can't open the config file user provided via command line args.)
132	Failed to parse the configuration file. (Includes the syntax error / line number to help user fix it.)
133	Configuration file is missing setting that has no default / fallback.
134	Configuration file has setting with invalid value.
14x	Errors preparing to execute commands.
140	Command does not exist.
141	Command is deprecated.
142	Invalid arguments for command.
143	Command is temporarily unavailable. (such as waiting for required components to start)
144	Command is permanently unavailable. (such as when required component was intentionally configured not to start)
2xx	Networking
20x	General connectivity.
201	No internet connection.
202	Router does not support UPnP.
21x	Wallet server connectivity.
210	Failed connecting to a lbryumx server. (Should normally not need to be handled higher up as lbrynet will retry other servers.)
211	Failed connecting to all known lbryumx servers. (Will need to bubble up and require user to do something.)
212	lbryumx droppped our connection. (Maybe we were being bad?)
22x	Wallet connection dropped.
220	Disconnected from lbryumx server due to suspicious responses. generic
221	Disconnected from lbryumx server due to SPV validation failure.
222	Disconnected from lbryumx server due to incorrect header received.
228	Disconnected from lbryumx server due to incompatible protocol version.
229	Disconnected from lbryumx server due to unresponsiveness.
23x	P2P connection errors.
24x	P2P download errors.
240	Failed to download blob. generic
25x	P2P upload errors.
26x	DHT connectivity issues.
27x	DHT protocol issues.
3xx	Blockchain
30x	Transaction rejected.
300	Transaction rejected, unknown reason.
301	Fee too low.
302	Invalid signature.
31x	Insufficient funds. (determined by wallet prior to attempting to broadcast a tx; this is different for example from a TX being created and sent but then rejected by lbrycrd for unspendable utxos.)
310	Not enough LBC to cover the transaction, even after all UTXOs reach 6 confirmations.
311	Not enough LBC to cover the transaction, will be enough after some more confirmations.
32x	Channel signing.
320	Channel signing key not found.
321	Channel signing key is out of date. (For example, channel was updated but you don't have the updated key.)
