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, 3.6.x, 3.7.x, 3.8.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, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: arangodb/backlog#508 (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, 3.6.x, 3.7.x, 3.8.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, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: N/A |
| 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, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: arangodb/backlog#679 (internal) |
| Date Added: 2021-06-08 Component: Analyzers Deployment Mode: All Description: Some implementation and usability issues were found with the new stopwords Analyzers. Therefore, it was removed from documentation for the time being. Technically, it is available in v3.8.0, but its usage is strongly discouraged until an improved version is released with v3.8.1. Affected Versions: 3.8.0 Fixed in Versions: 3.8.1 Reference: QA-66 (internal) |
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, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: arangodb/arangodb#6399 |
| Date Added: 2021-04-19 Component: AQL Deployment Mode: All Description: User-defined variable names in AQL cannot start with an underscore, in contrast to what the AQL documentation claimed. Affected Versions: 3.5.x, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: 3.9.0 Reference: arangodb/arangodb#13513 |
| Date Added: 2021-05-25 Component: AQL Deployment Mode: All Description: Global and per-query memory limits are not enforced for SHORTEST_PATH and K_SHORTEST_PATHS AQL graph traversals. Such queries may thus cause out-of-memory issues as they will not be killed despite exceeding the configured --query.memory-limit or Cursor API memoryLimit. Affected Versions: 3.5.x, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: 3.8.1 Reference: BTS-411 (internal) |
| Date Added: 2022-08-12 Component: AQL Deployment Mode: Cluster Description: Since ArangoDB 3.8, there was a loophole for creating duplicate keys in the same collection. This was only possible in cluster and needed an AQL query that copied over data from a collection (source) into another (target). The target collection must have more than one shard and must use a custom shard key. Inserting documents into the target collection must have happened via an AQL query like FOR doc IN source INSERT doc INTO target. In this particular situation, the document keys (_key attribute) from the source collection were used as-is for insertion into the target collection. However, as the target collection is not sharded by _key and uses a custom shard key, it is actually not allowed to specify user-defined values for _key. Versions before 3.8 failed with the error “must not specify _key for this collection” when running such an AQL query, but versions between 3.8.0 and 3.8.7 did not. Affected Versions: 3.8.0 - 3.8.7 Fixed in Versions: 3.8.8 Reference: arangodb/arangodb#16764 |
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, 3.6.x, 3.7.x, 3.8.x (Windows and Linux) Fixed in Versions: - Reference: arangodb/planning#3745 (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, 3.6.x, 3.7.x, 3.8.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, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: arangodb/release-qa#183 (internal) |
Hot Backup
| Issue |
|---|
| 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, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: N/A |
| Date Added: 2019-10-09 Component: Hot Backup API / arangobackup Deployment Mode: DC2DC Description: Hot Backup functionality in Datacenter-to-Datacenter Replication setups is experimental and may not work. Affected Versions: 3.5.x, 3.6.x, 3.7.x, 3.8.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, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: N/A |
| Date Added: 2021-08-06 Component: Coordinator Deployment Mode: Cluster Description: Restoring a hot backup to another deployment that has databases with the same names as in the backup can cause these databases to become inaccessible on Coordinators. They can be listed with db._databases() in arangosh, but not accessed using db._useDatabase(). Affected Versions: 3.6.x, 3.7.x, 3.8.x Fixed in Versions: 3.7.14, 3.8.1 Reference: BTS-527 (internal) |
Schema Validation
| Issue |
|---|
| Date Added: 2019-03-17 Component: Schema Validation Deployment Mode: All Description: The schema validation cannot pin-point which part of a rule made it fail. This is under investigation but very hard to solve for complex schemas. For example, when using not and anyOf, this would result in trees of possible errors. For now users should fall back to tools like jsonschemavalidator.net Affected Versions: 3.7.x, 3.8.x Fixed in Versions: - Reference: N/A |
| Date Added: 2019-03-17 Component: Schema Validation Deployment Mode: All Description: Remote schemas are not supported for security reasons. This limitation will likely remain unfixed. Affected Versions: 3.7.x, 3.8.x Fixed in Versions: - Reference: N/A |
| Date Added: 2019-06-25 Component: Schema Validation Deployment Mode: All Description: When using arangorestore for a collection with a defined schema, schema validation is not executed. Affected Versions: 3.7.x, 3.8.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: 2019-05-24 Component: Web UI Deployment Mode: Active Failover Description: The web interface shows a wrong replication mode in the replication tab in Active Failover deployments sometimes. It may display Leader/Follower mode (the default value) because of timeouts if /_api/cluster/endpoints is requested too frequently. Affected Versions: 3.5.x, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: N/A |
| Date Added: 2019-04-03 Component: arangod Deployment Mode: Cluster Description: Updating the properties of a collection in the cluster may return before the properties are updated consistently on all shards. This is especially visible when setting a schema for a collection with multiple shards, and then instantly starting to store non-conforming documents into the collection. These may be accepted until the properties change has been fully propagated to all shards. Affected Versions: 3.7.x, 3.8.x Fixed in Versions: - Reference: N/A |
| Date Added: 2021-04-07 Component: arangod Deployment Mode: All Description: The Batch API (HTTP endpoint /_api/batch) cannot be used in combination with Stream transactions to submit batched requests, because the required header x-arango-trx-id is not forwarded. It only processes Content-Type and Content-Id. Affected Versions: 3.5.x, 3.6.x, 3.7.x, 3.8.x Fixed in Versions: - Reference: arangodb/arangodb#13552 |
| Date Added: 2021-07-09 Component: Web UI Deployment Mode: All Description: When clicking the LOGS menu entry in the web interface for the second time, the view becomes unresponsive and does not display any data. Reloading the web interface helps to work around the problem. Affected Versions: 3.8.0 Fixed in Versions: - Reference: BTS-507 (internal) |
| Date Added: 2021-08-06 Component: Installer Deployment Mode: Single Server Description: The Windows installer fails during database initialization with the error failed to locate tzdata if there are non-ASCII characters in the destination path. Affected Versions: 3.8.x Fixed in Versions: - Reference: BTS-531 (internal) |
| Date Added: 2022-01-31 Component: ArangoSync, SmartGraphs Deployment Mode: DC2DC Description: In a DC2DC replication scenario, when you try to replicate a Disjoint Smartgraph, the sync of collections may get stuck. Affected Versions: 3.7.x, 3.8.x Fixed in Versions: 3.8.7 Reference: BTS-737 (internal) |
| Date Added: 2022-05-30 Component: ArangoSync Deployment Mode: DC2DC Description: In a DC2DC replication scenario, _users collection may fail to be replicated. Affected Versions: 3.8.x Fixed in Versions: - Reference: BTS-854 (internal) |
| Date Added: 2022-09-29 Component: ArangoDB Starter Deployment Mode: All Description: The ArangoDB Starter may fail to pick a Docker container name from cgroups. Affected Versions: 3.8.x Fixed in Versions: - Reference: GT-207 (internal) |
| Date Added: 2022-10-26 Component: ArangoSync Deployment Mode: DC2DC Description: When upgrading from/to 3.8.8, the _analyzers collection cannot be replicated. Affected Versions: 3.8.8 Fixed in Versions: 3.8.9 Reference: BTS-1094 (internal) |
