3.1.4 - 21 October 2020

Changes

Core

• DirectIO support was removed because of stability issues
• Missed ridbag containers are created on storage open
• Re-try in backup if atomic moves are not supported. Empty backup directory is created
• Handled the case when the locale is not defined in the database
• Fix index iterations in TX with both create and delete of the same element. Resolves Issue #9402
• Disc deserialization do not mark dirty collections anymore
• Errors during cluster truncation are not re-thrown
• Server memory usage limit was removed
• Startup metadata are moved without atomic move if such option is not supported
• If Bonsai tree already deleted we do not try to delete it again

TinkerPop 2.6

• Fix backward compatibility issue with custom TinkerPop predicates

3.1.3 - 30 September 2020

Changes

Core

• Use SequenceOrderType.ORDER_POSITIVE as default for sequence order type
• Events in WAL are fired only once
• Fix NPE during acquiring of component lock
• Stop accepting new requests if limit of memory consumption is reached Issue #9387
• Prevention of deletion of WAL segment if data is not written in that segment yet
• Fix security context creation to avoid race conditions (deadlock)
• StorageStartupMetadata made durable. During backup of database in distributed storage all file operations are checked on success and DB move made atomic.

SQL

• Fix usage of composite indexes with index chains
• Fix usage of indexes with subqueries (colleciton results)
• Fix NPE on count() on non existing class
• Fix shortestPath() with multiple edge types Issue #9388

Distributed

• make sure to return valid value on distributed status even if no value present
• update to Hazelcast 3.12.8
• avoided to run database sync from message executor
• serialized rid allocation execution for distributed
• reduced length of locking of whole cluster for insert to only messages executions
• add check for ridbag missing in delta deserialization

3.1.2 - 20 August 2020

Changes

Core

• moved storage replace in session on background to avoid deadlocks
• Fixed NPE when trying to update a vertex that has an rid bag
• Ensure that file writes are finished on close
• Parameter to setup value of minimal compressed record size for WAL was introduced
• Infinite loop in case of restore was fixed
• Index check was removed from database check
• fixed timer creation in remote context
• managed correctly storage frozen status from transactions and sync
• Incremental backup does not introduce GC overhead
• Fix console output on CREATE INDEX
• add validation for embedded collections when creating properties in the schema
• Fix csv export (http) to also use schema to infer columns
• Improve logging of errors related to exceeded packet size (remote binary)
• Tracking of labels without vertex classes was disabled
• re-introduced record not found instead illegal argument in case of cluster not there

SQL

• Improve management of TIMEOUT in SQL for aggregations and ORDER BY
• Fix regression on SQL range queries with indexes

Distributed

• add reentrant logic to distributed lock hazelcast implementation
• first definition of the new executor for distributed requests
• passed list of rids from first phase to the second phase to make sure to follow the same locking logic
• fixed distributed executor thread factory
• handled the case of rejectd execution in distributed executor
• changed the database drop to not wait for the distributed executor shutdown
• add unique index keys to tx phase 1
• add some buffering in the distributed executor queue
• add tracking of transactions pending in the distributed executor queue
• add unique keys for execution scheduling in distributed second phase
• add transaction id partition as locking key for schedule operation sequential
• add check for transaction already included in the database due to synch appening while the transaction is active
• add check for avoid to apply second phases if the state already contains the transactions
• changed first phase to return invalid sequential in case of already present transaction id
• add coordinator scheduler locking for distributed tx
• add reset to temporary id for created record in transaction, in case of retry for concurrent create
• add context registration for already present transaction to avoid trigger sync
• removed wait in execution of distributed tasks that was not needed and could cause deadlocks
• fixed wrong cluster drop logic in distributed implementation

3.1.1 - 8 July 2020

Changes

Core

• Fix concurrency issues with security cache
• Fix IMPORT from 3.0.x to 3.1.x
• Fix race usage of unique field in tx issue #9281
• Fix import so that only records which exist in database before import are over written.
• Broken files are detected in DWL during restore
• Out of bounds error was fixed in DWL
• Fix detection of memory cgroups
• Performance statistic monitoring was removed because were not completed and out of date Issue #9169
• Add implementation for automatic close for idle sockets
• remove use of ODocumentSerializable from global properties
• fixed wrong usage of mutable schema in place where immutable is available
• Fix binary version of config properties
• Fix StringIndexOutOfBoundsException
• Fix data flush in background and system stuck
• Fix usage of ZFS
• In cache entries atomic fields replaced by atomic field updaters
• fixed global config dump issue introduced in 3.1

SQL

• Fix usage of $matched in MATCH statements
• Fix count(*) with LIMIT
• Added interval() function
