Not working with orientdb 3.0

[tjtimer]

I can't connect to my orientdb (version 3.0) database.

Same here. Not sure if this project is still active? It seems to have been a while since last commit.

i just updated the constants.py to support the lastest protocol 37 and its working, but not sure if it has any implications. Here is the working pyorient module for orientdb3.0.0 https://github.com/rrmerugu/pyorient/ you can install with pip install git+https://github.com/rrmerugu/pyorient/

[Ostico]

Should be tested, some internal changes could be happened. This requires manual test and debug.

[Ostico]

You can try, but keep in mind that this is not production ready.

[rrmerugu]

@Ostico is there any roadmap to support 3.0.0 soon ?

Same problem here.
pyorient 1.5.5
orientdb 3.0.2

[OrientDBColin]

Starting with OrientDB 3.0.3, it adds a check to protocol 37 during the connect phase to see if a handshake is used. If a client specifies it supports protocol 37 but does not perform an initial handshake, it will fail.

The simplest solution is to still use protocol 36 (OrientDB will adjust accordingly) until the handshake, etc. can be implemented and to comment out this in orient.py:

        if self.protocol > SUPPORTED_PROTOCOL:
            raise PyOrientWrongProtocolVersionException(
                "Protocol version " + str(self.protocol) +
                " is not supported yet by this client.", [])

@Ostico could we comment that out, test it, and publish it to pip?

[OrientDBColin]

I went ahead and commented the protocol check out so that, at least, it will communicate with OrientDB 3.0.x now.

Your mileage may vary...

[Ostico]

Tested and checked with PHPOrient, this solution works, i will update pyOrient also as soon as possible

@Ostico when can you updata it? I have the same problem.

[thenesk]

@Ostico, @mogui, any chance we could get this patch pushed to pypi?

[Cornoualis]

Until it's pushed to pypi, you can install the module via:
pip install git+https://github.com/orientechnologies/pyorient
