OSBTreeRidBag cannot be cast to OEmbeddedRidBag

[johny65]

OrientDB Version: 3.1.6

Java Version: openjdk version "11.0.9.1"

OS: Ubuntu 20.10

Expected behavior

To activate the tree implementation of ridbags (setting -DridBag.embeddedToSbtreeBonsaiThreshold = -1) and use the database without problems, as the documentation says: "By default newly created RidBags are embedded and they are automatically converted to tree-based after reaching a threshold." This works fine in 3.0.x version.

Actual behavior

When the mentioned option is set, all vertices are unusable. The following exception is thrown:

Steps to reproduce

• Open the server with default options.
• In console:

$ orientdb> create database remote:localhost/test2 root pass;

Creating database [remote:localhost/test2] using the storage type [PLOCAL]...
Database created successfully.

Current database is: remote:localhost/test2

$ orientdb {db=test2}> script sql
[Started multi-line command. Type just 'end' to finish and execute]
orientdb {db=test2}> let $v1 = create vertex V set name = 'V1';
orientdb {db=test2}> let $v2 = create vertex V set name = 'V2';
orientdb {db=test2}> create edge from $v1 to $v2;
orientdb {db=test2}> end

• Now open server with -DridBag.embeddedToSbtreeBonsaiThreshold = -1.
• In console:

$ orientdb> connect remote:localhost/test2 admin admin;
IMPORTANT! Using default password is unsafe, please change password for user 'admin' on database 'test2'
Connecting to database [remote:localhost/test2] with user 'admin'...OK
orientdb {db=test2}> select from v;

Error: com.orientechnologies.common.io.OIOException

Error: java.io.EOFException

Taggin myself in here, as I am experiencing this observation, too!

@tglman this does not seem to have fixed with 3.2.18. I have observed the same behavior with 3.2.18

Hi,

I figured out why this happen, sometimes the server may have a setting that do not ever embedded ridbag, but the client still create that and send them to the server, but the server following the server setting fail in the cast, the specific cast was actually not needed I changed it to a more generic, this should be fixed in the next hotfix 3.2.23

Regards

Hi,

the 3.2.23 is out, closing this.
