pyln.client gossmap support #4582
Commits on Sep 7, 2021
-
pyln-spec: update to latest version of the spec.
Changelog-Changed: pyln-spec: updated to latest BOLT versions. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
pyln.client: don't try to use module inside setup.py.
This fails once it has dependencies (next patch): instead extract version manually. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
pyln.client: new functionality to access Gossmap.
It doesn't do much work, but it does parse the gossmap file and extract nodes and channels. [ Fixup by Michael Schmoock <michael@schmoock.net> ] Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
pyln-client/gossmap: save deconstructed fields instead of raw msg bytes.
We have to parse them anyway, so why not make them accessible. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
pyln-client/gossmap: add a little documentation.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
pyln-proto: expose ShortChannelId and PublicKey.
They're generally useful. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
pyln-client/gossmap: use ShortChannelId class from pyln.proto, if ava…
…ilable. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
pyln-client/gossmap: add NodeId class.
This is more efficient than converting them all to Pubkeys: about 3.8 seconds vs 5.4 seconds. Usually treating them as raw bytes is what we want anyway. [ Fixup by Michael Schmoock <michael@schmoock.net> ] Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

pyln-client/gossmap: adds channel satoshi capacity
This reads the `gossip_store_channel_amount` that always follows the `channel_announcement` messages. Therefore it uses an internal variable _last_scid to know what channel has been added last time.

pyln-client/gossmap: Don't mix bytes and GossmapNodeId
Do not mix bytes and GossmapNodeId when accessing Gossmap.nodes dicts. Therefore the definion got GossmapNodeId also needed to be pulled to the beginning of the file.

pyln-client/gossmap: more fixes, make mypy happier.
Mainly fixing type annotations, but some real fixes: 1. GossmapHalfchannel.from_str() should be a classmethod. 2. update_channel had weird, unusable default values (fields can't be NULL, since we use it below). [ There was one more occurence where isinstance should be used above type() == xyz comparison. -- MS ] Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

pyln-client/gossmap: make test gossip_store include channel_updates, …
…deletions. Suggested-by: @mschmook Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
pyln-client/gossmap: have channels link to their nodes instead of id
This is likely easier for programmers and does not use more mem as we already load all this.
-
pyln-client/gossmap: init GossmapNode and Id also with hexstring
also improves test coverage Changelog-Added: pyln-client: routines for direct access to the gossip store as Gossmap
-
pyln-client: fix mypy warnings, fix and test deletion of a channel.
This only happens when a deletion is added by a running gossipd, so we put a deletion at the end of the store to test it. mypy noticed that this code was nonsensical, so clearly untested. The testing noticed that making a nodeid from a string was also buggy. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
