continuum - P2P replicated document storage service

	Commit message (Collapse)	Author	Age	Files	Lines
*	add state fileHEAD master	tv	11 hours	7	-4/+266
\| \| \| \| \|	This allows storing the swarm ID and additionally discovered seeds, which prevents a formerly genesis node to start a new document.
*	put swarm ID into the document	tv	11 hours	4	-6/+27
\|
*	add genesis flag and never give up	tv	11 hours	3	-76/+112
\| \| \| \| \| \| \| \| \|	The --genesis flag has been introduced to start with a new document. This prevents restarts to accidentally start with a new document and accept reads/writes, causing a second swarm to appear. Additionally, bootstrapping doesn't timeout anymore as that's of no use for nobody.
*	compact remake fixes base at the commit	tv	24 hours	5	-40/+138
\| \| \| \| \| \| \|	Instead of fixing base heads at when proposed, compact fixes them when committing. This shrinks the window where writes can be lost if their author restarts to the switch delay; during replace and import remakes writes can still be lost during the voting period.
*	fix wording around swarm key admission	tv	25 hours	2	-3/+3
\|
*	allow superseding expired remakes	tv	25 hours	4	-26/+279
\|
*	remake coordinators resume after restart	tv	25 hours	3	-5/+49
\|
*	don't commit expired remakes	tv	25 hours	1	-58/+93
\|
*	add votes register	tv	26 hours	8	-124/+507
\|
*	bound stable-hub degree	tv	27 hours	1	-4/+46
\| \| \| \| \| \|	Each stable member can be preferred at most by 4*k members. The budget is spent in key order, which is the same on every node, so the graph stays deterministic, symmetric and connected.
*	coalesce announcements	tv	27 hours	3	-2/+60
\|
*	cache heads	tv	27 hours	7	-24/+61
\| \| \| \|	To reduce the number of write locks, heads are now cached.
*	corroberate newer epochs	tv	27 hours	1	-11/+53
\|
*	follow and download from ready members only	tv	27 hours	3	-3/+29
\|
*	being caught up needs some heads	tv	28 hours	1	-5/+9
\| \| \| \| \| \| \| \| \| \| \|	A sync message from a ready peer only completes the initial sync if that peer has at least one head. A peer with an empty document can no longer make a joiner ready on an empty store: a misconfigured second swarm, or a genesis node in its first seconds. Effect on a brand-new swarm: a joiner now waits until the genesis node has registered itself in the member list, which happens within about 5 s of it becoming ready.
*	only protocol-writers may modify _continuum	tv	28 hours	6	-14/+63
\|
*	put remake content into blobs	tv	29 hours	15	-79/+319
\|
*	add chunked download and use it during rejoin	tv	31 hours	15	-3/+844
\|
*	allow unsetting config options	tv	32 hours	2	-46/+264
\|
*	add API and CLI to print effective config	tv	32 hours	4	-2/+106
\|
*	add configuration files	tv	32 hours	4	-107/+1261
\|
*	wire up --mycelium-tcp-listen-port	tv	32 hours	1	-2/+5
\| \| \| \| \|	It wasn't used before, causing the supervised daemon to always pick a random one.
*	introduce majority voting on remakes	tv	34 hours	7	-95/+406
\|
*	add electorate	tv	34 hours	3	-8/+109
\| \| \| \| \|	For an upcoming change in remake coordination, nodes now maintain their self-assessed liveness in the document.
*	aliases are not in logs (fixup)	tv	34 hours	2	-2/+2
\|
*	measure document saved-size only after changes	tv	35 hours	2	-18/+43
\|
*	allow import remake using the raw document	tv	40 hours	1	-6/+85
\|

\|
*	add endpoint to export the document	tv	40 hours	3	-0/+88
\| \| \| \|	GET /admin/document to retrieve the automerge document.
*	add node aliases	tv	41 hours	6	-11/+147
\|
*	expose stats for prometheus to scrape	tv	41 hours	2	-7/+514
\|
*	add throughput stats	tv	41 hours	8	-2/+231
\|
*	add propagation stats	tv	41 hours	4	-1/+126
\|
*	add per peer incident stats	tv	41 hours	4	-4/+52
\|
*	expose stats via the API	tv	41 hours	2	-0/+136
\| \| \| \|	GET /admin/stats to retrieve all stats.
*	add swarm stats	tv	41 hours	9	-1/+238
\|
*	add traffic counter	tv	41 hours	9	-12/+270
\| \| \| \| \| \| \| \| \| \|	This introduces a new wrapper that counts messages and payload bytes per peer, split by kind (hello, helloReply, sync, ping, pong), each sent, received and refused. The traffic counter goes around the firewall, which means messages dropped outbound are still counted as sent, and messages dropped inbound don't count as received.
*	nodes prefer stable neighbours	tv	42 hours	1	-10/+89
\|
*	assess swarm stability	tv	42 hours	8	-11/+330

*	record RTT sampling instant	tv	42 hours	4	-30/+104

\|
*	record RTT from keepalive messages	tv	43 hours	7	-20/+148
\|
*	pull missing changes	tv	43 hours	7	-5/+162
\| \| \| \| \| \|	Nodes push changes to their neighbours but don't relay them directly. In a partial mesh, nodes can learn about missing changes via keepalive messages and can pull them from their neighbours.
*	find reachable neighbours	tv	43 hours	3	-55/+162
\|
*	sync with neighbours	tv	43 hours	6	-4/+171
\|
*	add neighbour graph	tv	44 hours	2	-0/+180
\|
*	add member registry	tv	44 hours	4	-1/+73
\|
*	use nonce in handshake	tv	44 hours	5	-2/+39
\| \| \| \| \|	To prevent stale hello replies to cause joins and thus stale sessions, each run gets a random ID, which used as nonce in the handshake.
*	drain queued messages on startup	tv	44 hours	1	-2/+48
\|
*	consolidate backoff code	tv	44 hours	4	-49/+99
