      neonet/newlink: Fix lost conn in encoding detector · f6b59772
      Levin Zimmermann authored
      If the peers encoding is different than our encoding two different
      scenarios can happen, because the handshake order is undefined (e.g.
      we don't know if our handshake is received before the peer sends its
      handshake):
      
      1. Our handshake is received before peer sends its handshake, NEO/py
      closes connection if it sees unexpected magic, version, etc.
      
      2. The client already sends a handshake before it proceeds our handshake.
      In this case it initally sends us it version, we can extract its encoding,
      and only later, once it proceeded our handshake with the bad encoding,
      it closes the connection.
      
      Before this patch case (2) wasn't handled correctly by the automatic
      encoding detection of 'DialLink'. 'DialLink' simply accepted the
      different-than-expected encoding, but once the peer proceeded the nodes
      handshake the peer closed the connection and the initially established
      and returned link was immediately closed again. Due to this it was good
      luck whether connecting with a peer different with an encoding different
      from the expected one worked or didn't work (it depended on which handshake
      was faster). Now 'DialLink' should reliably find the correct encoding
      and return a stable link.

      Y client: Adjust URI scheme to move client-specific options to fragment · 4c9414ea
      Kirill Smelkov authored
      For example option `compress` controls kind of compression that _client_
      performs when saving data to server. Similarly cache-size, logfile and
      read-only adjust on-client behaviour, not server.
      
      From nexedi/neoppod!18 (comment 124725) :
      
          In general the most correct thing to do is:
      
          - use host part for where to connect (host:port, list of host ports, UNIX socket, etc)
          - use path part to identify a database or other on-server resource
          - use query part for parameters that are passed to remote server (e.g. `storage` in case of ZEO)
          - use fragment part for local parameters that are not passed to remote server (e.g. local `logfile`)
          - use credentials part for things required to authenticate/encrypt.
      
          To normalize an URL wcfs client would drop credentials and fragment, but keep host, path and query.
      
          Fragments are documented not to be sent to remote side and to be evaluated by local side only.
      
      -> Move options that control client behaviour to fragment.

      Y client: Don't allow master_nodes and name to be present in options · 6047f893
      Kirill Smelkov authored
      Because list of masters and cluster name must be already present in
      netloc and path. Previously e.g.
      
      	neo://α,β,γ/db?master_nodes=a,b,c"
      
      would mean to use master nodes {a,b,c} not {α,β,γ}. Now it is treated as
      invalid URI to remove ambiguity. Same for cluster name.

      X go/neo: Fix credentials parsing with go1.17 · 87199da2
      Kirill Smelkov authored
      Due to security concerns, go1.17, even though very reluctantly,
      similarly to Python broke backward compatibility and stopped to treat ';'
      as separator when parsing URL queries.
      
      We still want to accept ';' as separator in credential part.
      -> Work it around by replacing ';' -> to '&'.
      
      See https://golang.org/doc/go1.17#semicolons and https://github.com/golang/go/issues/25192 for context.

      fixup! Y client: Fix URI scheme to move credentials out of query · cf685fb5
      Kirill Smelkov authored
      parse_qsl no longer treats ';' as valid query separator for security
      reason because most proxies did not do so and it was possible to poison
      proxy cache due to difference in query separator handling (see bugs.python.org/issue42967).
      
      To handle credentials we don't have any proxy here, and it is still
      perfectly valid to use ';' as credentials separator.
      
      -> Fix it with ';' -> '&' replace workaround, before feeding credentials
      string to parse_qsl.
      
      Amends: b9a42957.
