Felix Lange	7d5ff770e2	p2p/discover: continue reading after temporary errors ... Might solve #1579	9 years ago
Felix Lange	0d10d5a0a5	p2p: fix value of DiscSubprotocolError ... We had the wrong value (12) since forever.	9 years ago
Felix Lange	590c99a98f	p2p/discover: fix UDP reply packet timeout handling ... If the timeout fired (even just nanoseconds) before the deadline of the next pending reply, the timer was not rescheduled. The timer would've been rescheduled anyway once the next packet was sent, but there were cases where no next packet could ever be sent due to the locking issue fixed in the previous commit. As timing-related bugs go, this issue had been present for a long time and I could never reproduce it. The test added in this commit did reproduce the issue on about one out of 15 runs.	9 years ago
Felix Lange	01ed3fa1a9	p2p/discover: unlock the table during ping replacement ... Table.mutex was being held while waiting for a reply packet, which effectively made many parts of the whole stack block on that packet, including the net_peerCount RPC call.	9 years ago
Felix Lange	6ee908848c	p2p/nat: disable UPnP test on windows	9 years ago
Felix Lange	b23b4dbd79	p2p/discover: close Table during testing ... Not closing the table used to be fine, but now the table has a database.	9 years ago
Felix Lange	5c949d3b3b	fdtrack: temporary hack for tracking file descriptor usage ... Package fdtrack logs statistics about open file descriptors. This should help identify the source of #1549.	9 years ago
Felix Lange	bfbcfbe4a9	all: fix license headers one more time ... I forgot to update one instance of "go-ethereum" in commit 3f047be5a.	9 years ago
Felix Lange	3f047be5aa	all: update license headers to distiguish GPL/LGPL ... All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".	9 years ago
Ethan Buchman	37efd08b42	p2p: validate recovered ephemeral pubkey against checksum in decodeAuthMsg	9 years ago
Felix Lange	bdae4fd573	all: add some godoc synopsis comments	9 years ago

Péter Szilágyi	01fe972113	cmd, core, eth, metrics, p2p: require enabling metrics	9 years ago
Péter Szilágyi	216fc267fa	p2p: fix local/remote cap/protocol mixup	9 years ago
Péter Szilágyi	d84638bd31	p2p: support protocol version negotiation	9 years ago
Péter Szilágyi	6994a3daaa	p2p: instrument P2P networking layer	9 years ago
Felix Lange	6fb810adaa	p2p: throttle all discovery lookups ... Lookup calls would spin out of control when network connectivity was lost. The throttling that was in place only took effect when the table returned zero results, which doesn't happen very often. The new throttling should not have a negative impact when the host is online. Lookups against the network take some time and dials for all results must complete or hit the cache before a new one is started. This usually takes longer than four seconds, leaving online lookups unaffected. Fixes #1296	9 years ago
Felix Lange	70da79f04c	p2p: improve disconnect logging	9 years ago
Felix Lange	8dcbdcad0a	p2p: track write errors and prevent writes during shutdown ... As of this commit, we no longer rely on the protocol handler to report write errors in a timely fashion. When a write fails, shutdown is initiated immediately and no new writes can start. This will also prevent new writes from starting after Server.Stop has been called.	9 years ago
Felix Lange	a8e4cb6dfe	p2p/discover: use separate rand.Source instances in tests ... rand.Source isn't safe for concurrent use.	9 years ago
Felix Lange	261a8077c4	p2p/discover: deflake TestUDP_successfulPing	9 years ago
Péter Szilágyi	1cbbfbe7fa	p2p: fix a close race in the dial test	9 years ago
Felix Lange	3239aca69b	p2p: bump global write timeout to 20s ... The previous value of 5 seconds causes timeouts for legitimate messages if large messages are sent.	9 years ago
Péter Szilágyi	ff84352fb7	p2p: fix close data race	9 years ago
Felix Lange	fc6a5ae3ec	p2p/nat: add timeout for UPnP SOAP requests	9 years ago

Péter Szilágyi	612f01400f	p2p/discover: bond with seed nodes too (runs only if findnode failed)	9 years ago
Péter Szilágyi	3630432dfb	p2p/discovery: fix a cornercase loop if no seeds or bootnodes are known	9 years ago
Péter Szilágyi	f539ed1e66	p2p/discover: force refresh if the table is empty	9 years ago
Péter Szilágyi	5076170f34	p2p/discover: permit temporary bond failures for previously known nodes	9 years ago
Péter Szilágyi	6078aa08eb	p2p/discover: watch find failures, evacuate on too many, rebond if failed	9 years ago
Péter Szilágyi	64174f196f	p2p/discover: add support for counting findnode failures	9 years ago
Péter Szilágyi	68898a4d6b	p2p: fix Self() panic if listening is disabled	9 years ago
Péter Szilágyi	e1a0ee8fc5	cmd/geth, cmd/utils, eth, p2p: pass and honor a no discovery flag	9 years ago
Péter Szilágyi	278183c7e7	eth, p2p: start the p2p server even if maxpeers == 0	9 years ago
Felix Lange	9e1fd70b50	p2p: decrease frameReadTimeout to 30s ... This detects hanging connections sooner. We send a ping every 15s and other implementation have similar limits.	9 years ago
Felix Lange	1440f9a37a	p2p: new dialer, peer management without locks ... The most visible change is event-based dialing, which should be an improvement over the timer-based system that we have at the moment. The dialer gets a chance to compute new tasks whenever peers change or dials complete. This is better than checking peers on a timer because dials happen faster. The dialer can now make more precise decisions about whom to dial based on the peer set and we can test those decisions without actually opening any sockets. Peer management is easier to test because the tests can inject connections at checkpoints (after enc handshake, after protocol handshake). Most of the handshake stuff is now part of the RLPx code. It could be exported or move to its own package because it is no longer entangled with Server logic.	9 years ago
Felix Lange	9f38ef5d97	p2p/discover: add ReadRandomNodes	9 years ago
Felix Lange	64564da20b	p2p: decrease maximum message size for devp2p to 1kB ... The previous limit was 10MB which is unacceptable for all kinds of reasons, the most important one being that we don't want to allow the remote side to make us allocate 10MB at handshake time.	9 years ago
Felix Lange	dbdc5fd4b3	p2p: delete Server.Broadcast	9 years ago
Péter Szilágyi	cbd3ae6906	p2p/discover: fix #838, evacuate self entries from the node db	9 years ago
Péter Szilágyi	af24c271c7	p2p/discover: fix database presistency test folder	9 years ago
Felix Lange	d2f119cf9b	p2p/discover: limit open files for node database	9 years ago
Felix Lange	206fe25971	p2p: remove testlog	9 years ago
Felix Lange	7fa2607bd1	p2p/discover: bump maxBondingPingPongs to 16 ... This should increase the speed a bit because all findnode results (up to 16) can be verified at the same time.	9 years ago
Felix Lange	691cb90284	p2p: log remote reason when disconnect is requested ... The returned reason is currently not used except for the log message. This change makes the log messages a bit more useful. The handshake code also returns the remote reason.	9 years ago
Felix Lange	c14de2e973	p2p/nat: tweak port mapping log messages and levels ... People stil get confused about the messages. This commit changes the levels so that the only thing printed at the default level (info) is a successful mapping.	9 years ago
Felix Lange	663d4e0aff	p2p/nat: add test for UPnP auto discovery via SSDP ... The test listens for multicast UDP packets on the default interface because I couldn't get it to work reliably on loopback without massive changes to goupnp. This means that the test might fail when there is a UPnP-enabled router attached on that interface. I checked that locally by looping the test and it passes reliably because the local SSDP server always responds faster.	9 years ago
Felix Lange	983f5a717a	p2p/nat: fix concurrent access to autodisc Interface ... Concurrent calls to Interface methods on autodisc could return a "not discovered" error if the discovery did not finish before the call. autodisc.wait expected the done channel to carry the found Interface but it was closed instead. The fix is to use sync.Once for now, which is easier to get right. And there is a test. Finally. This will have to change again when we introduce re-discovery.	9 years ago
