Bug fixes and updates

Advance Warning

The following items are due to change in a future release.

  • Security

    • Starting from LogScale version 1.237, support for insecure ldap connections will be removed. Self-Hosted customers using LDAP will only be able to use ldaps secure connections.

  • Queries

    • Due to various upcoming changes to LogScale and the recently introduced regex engine, the following regex features will be removed in version 1.225:

      • Octal notation

      • Quantification of unquantifiable constructs

      Octal notation is being removed due to logic application difficulties and its tendency to make typographical errors easier to overlook.

      Here is an example of a common octal notation issue:

      regex
      /10\.26.\122\.128/

      In this example, \122 is interpreted as the octal escape for R rather than the intended literal 122. Similarly, the . matches not just the punctuation itself but also any single character except for new lines.

      Any construction of \x where x is a number from 1 to 9 will always be interpreted as a backreference to a capture group. If the correponding capture group does not exist, it will be an error.

      Quantification of unquantifiable constructs is being removed due to lack of appropriate semantic logic, leading to redundancy and errors.

      Unquantifiable constructs being removed include:

      • ^ (the start of string/start of line)

      • $ (the end of string/end of line)

      • ?= (a positive lookahead)

      • ?! (a negative lookahead)

      • ?<= (a positive lookbehind)

      • <?<!> (a negative lookbehind)

      • \b (a word boundary)

      • \B (a non-word boundary)

      For example, the end-of-text construct $* only has meaning for a limited number of occurrences. There can never be more than one occurrence of the end of the text at any given position, making elements like $ redundant.

      A common pitfall that causes this warning is when users copy and paste a glob pattern like *abc* in as a regex, but delimit the regex with start of text and end of text anchors:

      regex
      /^*abc*$/

      The proper configuration should look like this:

      regex
      /abc/

      For more information, see LogScale Regular Expression Engine V2.

Deprecation

Items that have been deprecated and may be removed in a future release.

  • The EXTRA_KAFKA_CONFIGS_FILE configuration variable has been deprecated and planned to be removed no earlier than version 1.225.0. For more information, see RN Issue.

  • rdns() has been deprecated and will be removed in version 1.249. Use reverseDns() as an alternative function.

  • The Secondary Storage feature is now deprecated and will be removed in LogScale 1.231.0.

    The Bucket Storage feature provides superior functionality for storing rarely queried data in cheaper storage while keeping frequently queried data in hot storage (fast and expensive). For more information, see Bucket Storage.

    Please contact LogScale support for any concerns about this deprecation.

New features and improvements

  • Automation and Triggers

    • Added a new action type for uploading the result of a trigger to an AWS S3 bucket.

      For more information, see Action Type: S3.

Known Issues

  • Storage

    • For clusters using secondary storage where the primary storage on some nodes in the cluster may be getting filled (i.e. the storage usage on the primary disk is halfway between PRIMARY_STORAGE_PERCENTAGE and PRIMARY_STORAGE_MAX_FILL_PERCENTAGE), those nodes may fail to transfer segments from other nodes. The failure will be indicated by the error java.nio.file.AtomicMoveNotSupportedException with message "Invalid cross-device link".

      This does not corrupt data or cause data loss, but will prevent the cluster from being fully healthy, and could also prevent data from reaching adequate replication.

Improvement

  • Functions

    • Using the readFile() function with the include argument will now output the columns in the order that the values were provided in the include array.
