ArangoSearch

Issue
Date Added: 2018-12-19
Component: ArangoSearch
Deployment Mode: Single-server
Description: Value of _id attribute indexed by ArangoSearch view may become inconsistent after renaming a collection
Affected Versions: 3.5.x
Fixed in Versions: -
Reference: arangodb/backlog#514  (internal)
Date Added: 2018-12-03
Component: ArangoSearch
Deployment Mode: Cluster
Description: Score values evaluated by corresponding score functions (BM25/TFIDF) may differ in single-server and cluster with a collection having more than 1 shard
Affected Versions: 3.4.x, 3.5.x
Fixed in Versions: -
Reference: arangodb/backlog#508  (internal)
Date Added: 2018-12-03
Component: ArangoSearch
Deployment Mode: Cluster
Description: ArangoSearch index consolidation does not work during creation of a link on existing collection which may lead to massive file descriptors consumption
Affected Versions: 3.4.x, 3.5.x
Fixed in Versions: 3.6.0
Reference: arangodb/backlog#509  (internal)
Date Added: 2018-12-03
Component: ArangoSearch
Deployment Mode: All
Description: Using a loop variable in expressions within a corresponding SEARCH condition is not supported
Affected Versions: 3.4.x, 3.5.x
Fixed in Versions: -
Reference: arangodb/backlog#318  (internal)
Date Added: 2019-06-25
Component: ArangoSearch
Deployment Mode: All
Description: The primarySort attribute in ArangoSearch View definitions cannot be set via the web interface. The option is immutable, but the web interface does not allow to set any View properties upfront (it creates a View with default parameters before the user has a chance to configure it).
Affected Versions: 3.5.x
Fixed in Versions: -
Reference: N/A
Date Added: 2019-11-06
Component: ArangoSearch
Deployment Mode: Cluster
Description: There is a possibility to get into deadlocks during Coordinator execution if a custom Analyzer was created (and is present in the _analyzers system collection). It is recommended not to use custom Analyzers in production environments in affected versions.
Affected Versions: 3.5.x
Fixed in Versions: 3.5.3
Reference: arangodb/backlog#651  (internal)
Date Added: 2020-03-19
Component: ArangoSearch
Deployment Mode: All
Description: Operators and functions in SEARCH clauses of AQL queries which compare values such as >, >=, <, <=, IN_RANGE() and STARTS_WITH() neither take the server language (--default-language) nor the Analyzer locale into account. The alphabetical order of characters as defined by a language is thus not honored and can lead to unexpected results in range queries.
Affected Versions: 3.5.x
Fixed in Versions: -
Reference: arangodb/backlog#679  (internal)
Date Added: 2020-05-22
Component: ArangoSearch
Deployment Mode: Cluster
Description: The immediate recreation of ArangoSearch Analyzers in cluster deployments (deleting and shortly after creating one with the same name but different properties) causes errors in queries which involve such recreated Analyzers. For a workaround see Purge Analyzer cache below.
Affected Versions: 3.5.x
Fixed in Versions: -
Reference: arangodb/backlog#669  (internal), arangodb/backlog#695  (internal)
Date Added: 2020-07-31
Component: ArangoSearch
Deployment Mode: All
Description: AQL queries with subqueries or joins in SEARCH expressions may return incorrect results. As a workaround, you can disable the optimizer rule which causes the problem with the following query options: { optimizer: { rules: [ "-inline-subqueries" ] } }
Affected Versions: 3.5.x, 3.6.x, 3.7.x
Fixed in Versions: -
Reference: arangodb/arangodb#12247 

Purge Analyzer cache

To fix query errors caused by an immediately re-created Analyzer, the DB-Servers need to be forced to clear their Analyzer caches. This can be achieved by using below code in arangosh:

  1. Connect to a Coordinator with arangosh

  2. var analyzers = require("@arangodb/analyzers");

  3. analyzers.remove("<PROBLEMATIC ANALYZER>");

  4. var dummy = "dummy_analyzer_" + Date.now();

  5. analyzers.save(dummy, "identity", {});

  6. db._query("FOR d IN <ANY EXISTING VIEW> SEARCH ANALYZER(STARTS_WITH(d.test, 'something'), @a) RETURN d", {a: dummy});

    This query with a new Analyzer will force cache purging. If this query reports an error about a missing Analyzer, then wait for a minute and retry until it succeeds.

  7. Re-create your Analyzer (<PROBLEMATIC ANALYZER>) with the new, correct properties.

  8. analyzers.remove(dummy);

  9. Check if the original query still fails. It is possible that it reports a missing Analyzer, but the problem should go away in a minute and the query execute normally.

AQL

Issue
Date Added: 2018-09-05
Component: AQL
Deployment Mode: Cluster
Description: In a very uncommon edge case there is an issue with an optimization rule in the cluster. If you are running a cluster and use a custom shard key on a collection (default is _key) and you provide a wrong shard key in a modifying query (UPDATE, REPLACE, DELETE) and the wrong shard key is on a different shard than the correct one, a DOCUMENT NOT FOUND error is returned instead of a modification (example query: UPDATE { _key: "123", shardKey: "wrongKey"} WITH { foo: "bar" } IN mycollection). Note that the modification always happens if the rule is switched off, so the suggested workaround is to deactivate the optimizing rule restrict-to-single-shard.
Affected Versions: 3.4.x, 3.5.x
Fixed in Versions: -
Reference: arangodb/arangodb#6399 

Upgrading

Issue
Date Added: 2019-05-16
Component: arangod
Deployment Mode: All
Description: Bugfix release upgrades such as 3.4.4 to 3.4.5 may not create a backup of the database directory even if they should. Please create a copy manually before upgrading.
Affected Versions: 3.4.x, 3.5.x (Windows and Linux)
Fixed in Versions: -
Reference: arangodb/planning#3745  (internal)
Date Added: 2019-11-06
Component: arangod
Deployment Mode: All
Description: Upgrades from ArangoDB version 3.4.x to 3.5.0 or 3.5.1 don’t create the _analyzers system collection, preventing creation and use of custom Analyzers.
Suggested workaround: Create the missing collection manually in each database of an ArangoDB deployment after upgrade (arangosh example: db._create("_analyzers", {isSystem: true}))
Affected Versions: 3.5.0, 3.5.1
Fixed in Versions: 3.5.2
Reference: arangodb/backlog#652  (internal)
Date Added: 2019-11-06
Component: arangod
Deployment Mode: Cluster
Description: Rolling cluster upgrades from ArangoDB version 3.5.0 to 3.5.1 are not possible due to errors at DB-Server nodes. A fix is contained from version 3.5.2 on, and rolling upgrades to this version are possible.
Affected Versions: 3.5.0, 3.5.1
Fixed in Versions: 3.5.2
Reference: arangodb/backlog#652  (internal)
Date Added: 2019-12-10
Component: Installer
Deployment Mode: All
Description: The NSIS installer for Windows may fail to upgrade an existing installation, e.g. from 3.4.a to 3.4.b (patch release), with the error message: “failed to detect whether we need to Upgrade”
Affected Versions: 3.4.x, 3.5.x
Fixed in Versions: -
Reference: arangodb/release-qa#183  (internal)
Date Added: 2020-01-07
Component: Installer
Deployment Mode: All
Description: The NSIS installer for Windows can fail to add the path to the ArangoDB binaries to the PATH environment variable, silently or with an error.
Affected Versions: 3.4.x, 3.5.x
Fixed in Versions: -
Reference: arangodb/release-qa#183  (internal)
Date Added: 2020-12-18
Component: Agency
Deployment Mode: Cluster
Description: When upgrading a cluster from 3.5.x to 3.6.10, the upgrade can get stuck. Please update to 3.5.7 first before you upgrade to 3.6.10. If you are already in this situation, then you need to kill the stuck Agent. In a Kubernetes environment, use kubectl to get a list of all ArangoDB pods. You should see that one of the Agent pods has not yet restarted. Check the log file for a line like control-c received near the end, followed by no or only a few more log lines. Kill this pod with kubectl.
Affected Versions: 3.5.x, 3.6.10
Fixed in Versions: 3.5.7
Reference: N/A

Stream Transactions

Issue
Date Added: 2019-08-19
Component: Transactions
Deployment Mode: All
Description: Stream Transactions do not honor the limits described in the documentation. Currently the idle timeout of 10 seconds will not be enforced, neither will the maximum size of transaction be enforced.
Affected Versions: 3.5.0
Fixed in Versions: 3.5.1
Reference: arangodb/arangodb#9775 
Date Added: 2019-08-19
Component: Transactions
Deployment Mode: All
Description: Stream Transactions do not support the graph operations that are initiated via the general-graph / smart-graph JavaScript module or via the REST API at /_api/gharial. These operations will act as if no stream transaction is present.
Affected Versions: 3.5.0
Fixed in Versions: 3.5.1
Reference: arangodb/arangodb#9855  / arangodb/arangodb#9911 
Date Added: 2019-08-19
Component: Transactions
Deployment Mode: All
Description: Stream Transactions do not support user restrictions. Any authenticated user may access any ongoing transaction so long as they have access to the database in question.
Affected Versions: 3.5.0
Fixed in Versions: 3.5.1
Reference: arangodb/arangodb#9796 

Hot Backup

Issue
Date Added: 2019-10-09
Component: Hot Backup API / arangobackup
Deployment Mode: All
Description: ArangoSearch Views are not backed up and thus not restored yet. Therefore, Views have to be dropped and recreated after a restore. This happens automatically in the background, but in particular in the presence of large amounts of data, the recreation of the ArangoSearch indexes can take some time after the restore. It is planned to rectify this limitation in one of the next releases.
Note furthermore that a running query with views can prevent a restore operation from happening whilst the query is running.
Affected Versions: 3.5.x
Fixed in Versions: 3.6.0
Reference: N/A
Date Added: 2019-10-09
Component: Hot Backup API / arangobackup
Deployment Mode: All
Description: The Hot Backup feature is not supported in the Windows version of ArangoDB at this point in time.
Affected Versions: 3.5.x
Fixed in Versions: -
Reference: N/A
Date Added: 2019-10-09

Affected Versions: 3.5.x
Fixed in Versions: -
Reference: N/A
Date Added: 2019-10-09
Component: arangobackup
Deployment Mode: All
Description: The startup option --operation works as positional argument only, e.g. arangobackup list. The alternative syntax arangobackup --operation list is not accepted.
Affected Versions: 3.5.x
Fixed in Versions: -
Reference: N/A

Other

Issue
Date Added: 2019-05-16
Component: Starter
Deployment Mode: All
Description: The ArangoDB Starter falls back to the IP [::1] under macOS. If there is no entry ::1 localhost in the /etc/hosts file or the option --starter.disable-ipv6 is passed to the starter to use IPv4, then it will hang during startup.
Affected Versions: 0.14.3 (macOS only)
Fixed in Versions: -
Reference: N/A
Date Added: 2019-05-16
Component: arangod
Deployment Mode: All
Description: Calling a shutdown endpoint may not result in a proper shutdown while the node/server is still under load. The server processes must be ended manually.
In v3.5.1 and later, two different issues are fixed: libgcc/libmusl wrongly detecting multi-threadedness in statically linked executables and a read/write lock race condition.
Affected Versions: 3.5.0
Fixed in Versions: 3.5.1
Reference: v3.5.1 CHANGELOG  / Blog Post “When Exceptions Collide” 
Date Added: 2019-05-24
Component: Web UI
