Changelog

5.2.0 (1 September 2017)

New Features

• Shrink action! Apologies to all who have patiently waited for this feature. It’s been a long time coming, but it is hopefully worth the wait. There are a lot of checks and tests associated with this action, as there are many conditions that have to be met in order for a shrink to take place. Curator will try its best to ensure that all of these conditions are met so you can comfortably rest assured that shrink will work properly unattended. See the documentation for more information.
• The cli function has been split into cli and run functions. The behavior of cli will be indistinguishable from previous releases, preserving API integrity. The new run function allows lambda and other users to run Curator from the API with only a client configuration file and action file as arguments. Requested in #1031 (untergeek)
• Allow use of time/date string interpolation for Rollover index naming. Added in #1010 (tschroeder-zendesk)
• New unit_count_pattern allows you to derive the unit_count from the index name itself. This involves regular expressions, so be sure to do lots of testing in --dry-run mode before deploying to production. Added by (soenkeliebau) in #997

Bug Fixes

• Reindex request_body allows for 2 different size options. One limits the number of documents reindexed. The other is for batch sizing. The batch sizing option was missing from the schema validator. This has been corrected. Reported in #1038 (untergeek)
• A few sundry logging and notification changes were made.

5.1.2 (08 August 2017)

Errata

• An update to Elasticsearch 5.5.0 changes the behavior of filter_by_aliases, differing from previous 5.x versions.

  If a list of aliases is provided, indices must appear in _all_ listed aliases or a 404 error will result, leading to no indices being matched. In older versions, if the index was associated with even one of the aliases in aliases, it would result in a match.

  Tests and documentation have been updated to address these changes.

• Debian 9 changed SSL versions, which means that the pre-built debian packages no longer work in Debian 9. In the short term, this requires a new repository. In the long term, I will try to get a better repository system working for these so they all work together, better. Requested in #998 (untergeek)

Bug Fixes

• Support date math in reindex operations better. It did work previously, but would report failure because the test was looking for the index with that name from a list of indices, rather than letting Elasticsearch do the date math. Reported by DPattee in #1008 (untergeek)
• Under rare circumstances, snapshot delete (or create) actions could fail, even when there were no snapshots in state IN_PROGRESS. This was tracked down by JD557 as a collision with a previously deleted snapshot that hadn’t finished deleting. It could be seen in the tasks API. An additional test for snapshot activity in the tasks API has been added to cover this scenario. Reported in #999 (untergeek)
• The restore_check function did not work properly with wildcard index patterns. This has been rectified, and an integration test added to satisfy this. Reported in #989 (untergeek)
• Make Curator report the Curator version, and not just reiterate the elasticsearch version when reporting version incompatibilities. Reported in #992. (untergeek)
• Fix repository/snapshot name logging issue. #1005 (jpcarey)
• Fix Windows build issue #1014 (untergeek)

Documentation

• Fix/improve rST API documentation.
• Thanks to many users who not only found and reported documentation issues, but also submitted corrections.

>>>>>>> master

5.1.1 (8 June 2017)

Bug Fixes

• Mock and cx_Freeze don’t play well together. Packages weren’t working, so I reverted the string-based comparison as before.

5.1.0 (8 June 2017)

New Features

• Index Settings are here! First requested as far back as #160, it’s been requested in various forms culminating in #656. The official documentation addresses the usage. (untergeek)
• Remote reindex now adds the ability to migrate from one cluster to another, preserving the index names, or optionally adding a prefix and/or a suffix. The official documentation shows you how. (untergeek)
• Added support for naming rollover indices. #970 (jurajseffer)
• Testing against ES 5.4.1, 5.3.3

Bug Fixes

• Since Curator no longer supports old versions of python, convert tests to use isinstance. #973 (untergeek)
• Fix stray instance of is not comparison instead of != #972 (untergeek)
• Increase remote client timeout to 180 seconds for remote reindex. #930 (untergeek)

General

• elasticsearch-py dependency bumped to 5.4.0
• Added mock dependency due to isinstance and testing requirements
• AWS ES 5.3 officially supports Curator now. Documentation has been updated to reflect this.

5.0.4 (16 May 2017)

Bug Fixes

• The _recovery check needs to compare using != instead of is not, which apparently does not accurately compare unicode strings. Reported in #966. (untergeek)

5.0.3 (15 May 2017)

Bug Fixes

• Restoring a snapshot on an exceptionally fast cluster/node can create a race race condition where a _recovery check returns an empty dictionary {}, which causes Curator to fail. Added test and code to correct this. Reported in #962. (untergeek)

5.0.2 (4 May 2017)

Bug Fixes

• Nasty bug in schema validation fixed where boolean options or filter flags would validate as True if non-boolean types were submitted. Reported in #945. (untergeek)
• Check for presence of alias after reindex, in case the reindex was to an alias. Reported in #941. (untergeek)
• Fix an edge case where an index named with 1970.01.01 could not be sorted by index-name age. Reported in #951. (untergeek)
• Update tests to include ES 5.3.2
• Bump certifi requirement to 2017.4.17.

Documentation

• Document substitute strftime symbols for doing ISO Week timestrings added in #932. (untergeek)
• Document how to include file paths better. Fixes #944. (untergeek)

5.0.1 (10 April 2017)

Bug Fixes

• Fixed default values for include_global_state on the restore action to be in line with defaults in Elasticsearch 5.3

Documentation

• Huge improvement to documenation, with many more examples.
• Address age filter limitations per #859 (untergeek)
• Address date matching behavior better per #858 (untergeek)

5.0.0 (5 April 2017)

The full feature set of 5.0 (including alpha releases) is included here.

New Features

• Reindex is here! The new reindex action has a ton of flexibility. You can even reindex from remote locations, so long as the remote cluster is Elasticsearch 1.4 or newer.

• Added the period filter (#733). This allows you to select indices or snapshots, based on whether they fit within a period of hours, days, weeks, months, or years.

• Add dedicated “wait for completion” functionality. This supports health checks, recovery (restore) checks, snapshot checks, and operations which support the new tasks API. All actions which can use this have been refactored to take advantage of this. The benefit of this new feature is that client timeouts will be less likely to happen when performing long operations, like snapshot and restore.

  NOTE: There is one caveat: forceMerge does not support this, per the Elasticsearch API. A forceMerge call will hold the client until complete, or the client times out. There is no clean way around this that I can discern.

• Elasticsearch date math naming is supported and documented for the create_index action. An integration test is included for validation.

• Allow allocation action to unset a key/value pair by using an empty value. Requested in #906. (untergeek)

• Added support for the Rollover API. Requested in #898, and by countless others.

• Added warn_if_no_indices option for alias action in response to #883. Using this option will permit the alias add or remove to continue with a logged warning, even if the filters result in a NoIndices condition. Use with care.

General

• Bumped click (python module) version dependency to 6.7
• Bumped urllib3 (python module) version dependency to 1.20
• Bumped elasticsearch (python module) version dependency to 5.3
• Refactored a ton of code to be cleaner and hopefully more consistent.

Bug Fixes

• Curator now logs version incompatibilities as an error, rather than just raising an Exception. #874 (untergeek)
• The get_repository() function now properly raises an exception instead of returning False if nothing is found. #761 (untergeek)
• Check if an index is in an alias before attempting to delete it from the alias. Issue raised in #887. (untergeek)
• Fix allocation issues when using Elasticsearch 5.1+. Issue raised in #871 (untergeek)

Documentation

• Add missing repository arg to auto-gen API docs. Reported in #888 (untergeek)
• Add all new documentation and clean up for v5 specific.

Breaking Changes

• IndexList no longer checks to see if there are indices on initialization.

5.0.0a1 (23 March 2017)

This is the first alpha release of Curator 5. This should not be used for production! There will be many more changes before 5.0.0 is released.

New Features

• Allow allocation action to unset a key/value pair by using an empty value. Requested in #906. (untergeek)
• Added support for the Rollover API. Requested in #898, and by countless others.
• Added warn_if_no_indices option for alias action in response to #883. Using this option will permit the alias add or remove to continue with a logged warning, even if the filters result in a NoIndices condition. Use with care.

Bug Fixes

• Check if an index is in an alias before attempting to delete it from the alias. Issue raised in #887. (untergeek)
• Fix allocation issues when using Elasticsearch 5.1+. Issue raised in #871 (untergeek)

Documentation

• Add missing repository arg to auto-gen API docs. Reported in #888 (untergeek)

4.2.6 (27 January 2016)

General

• Update Curator to use version 5.1 of the elasticsearch-py python module. With this change, there will be no reverse compatibility with Elasticsearch 2.x. For 2.x versions, continue to use the 4.x branches of Curator.
• Tests were updated to reflect the changes in API calls, which were minimal.
• Remove “official” support for Python 2.6. If you must use Curator on a system that uses Python 2.6 (RHEL/CentOS 6 users), it is recommended that you use the official RPM package as it is a frozen binary built on Python 3.5.x which will not conflict with your system Python.
• Use isinstance() to verify client object. #862 (cp2587)
• Prune older versions from Travis CI tests.
• Update certifi dependency to latest version

Documentation

• Add version compatibility section to official documentation.
• Update docs to reflect changes. Remove cruft and references to older versions.

4.2.5 (22 December 2016)

General

• Add and increment test versions for Travis CI. #839 (untergeek)
• Make filter_list optional in snapshot, show_snapshot and show_indices singleton actions. #853 (alexef)

Bug Fixes

• Fix cli integration test when different host/port are specified. Reported in #843 (untergeek)
• Catch empty list condition during filter iteration in singleton actions. Reported in #848 (untergeek)

Documentation

• Add docs regarding how filters are ANDed together, and how to do an OR with the regex pattern filter type. Requested in #842 (untergeek)
• Fix typo in Click version in docs. #850 (breml)
• Where applicable, replace [source,text] with [source,yaml] for better formatting in the resulting docs.

4.2.4 (7 December 2016)

Bug Fixes

• --wait_for_completion should be True by default for Snapshot singleton action. Reported in #829 (untergeek)
• Increase version_max to 5.1.99. Prematurely reported in #832 (untergeek)
• Make the ‘.security’ index visible for snapshots so long as proper credentials are used. Reported in #826 (untergeek)

4.2.3.post1 (22 November 2016)

This fix is only going in for pip-based installs. There are no other code changes.

Bug Fixes

• Fixed incorrect assumption of PyPI picking up dependency for certifi. It is still a dependency, but should not affect pip installs with an error any more. Reported in #821 (untergeek)

4.2.3 (21 November 2016)

4.2.2 was pulled immediately after release after it was discovered that the Windows binary distributions were still not including the certifi-provided certificates. This has now been remedied.

General

• certifi is now officially a requirement.
• setup.py now forcibly includes the certifi certificate PEM file in the “frozen” distributions (i.e., the compiled versions). The get_client method was updated to reflect this and catch it for both the Linux and Windows binary distributions. This should finally put to rest #810

4.2.2 (21 November 2016)

Bug Fixes

• The certifi-provided certificates were not propagating to the compiled RPM/DEB packages. This has been corrected. Reported in #810 (untergeek)

General

• Added missing --ignore_empty_list option to singleton actions. Requested in #812 (untergeek)

Documentation

• Add a FAQ entry regarding the click module’s need for Unicode when using Python 3. Kind of a bug fix too, as the entry_points were altered to catch this omission and report a potential solution on the command-line. Reported in #814 (untergeek)
• Change the “Command-Line” documentation header to be “Running Curator”

4.2.1 (8 November 2016)

Bug Fixes

• In the course of package release testing, an undesirable scenario was caught where boolean flags default values for curator_cli were improperly overriding values from a yaml config file.

General

• Adding in direct download URLs for the RPM, DEB, tarball and zip packages.

4.2.0 (4 November 2016)

New Features

• Shard routing allocation enable/disable. This will allow you to disable shard allocation routing before performing one or more actions, and then re-enable after it is complete. Requested in #446 (untergeek)
• Curator 3.x-style command-line. This is now curator_cli, to differentiate between the current binary. Not all actions are available, but the most commonly used ones are. With the addition in 4.1.0 of schema and configuration validation, there’s even a way to still do filter chaining on the command-line! Requested in #767, and by many other users (untergeek)

General

• Update testing to the most recent versions.
• Lock elasticsearch-py module version at >= 2.4.0 and <= 3.0.0. There are API changes in the 5.0 release that cause tests to fail.

Bug Fixes

• Guarantee that binary packages are built from the latest Python + libraries. This ensures that SSL/TLS will work without warning messages about insecure connections, unless they actually are insecure. Reported in #780, though the reported problem isn’t what was fixed. The fix is needed based on what was discovered while troubleshooting the problem. (untergeek)

4.1.2 (6 October 2016)

This release does not actually add any new code to Curator, but instead improves documentation and includes new linux binary packages.

General

• New Curator binary packages for common Linux systems! These will be found in the same repositories that the python-based packages are in, but have no dependencies. All necessary libraries/modules are bundled with the binary, so everything should work out of the box. This feature doesn’t change any other behavior, so it’s not a major release.

  These binaries have been tested in:

  • CentOS 6 & 7
  • Ubuntu 12.04, 14.04, 16.04
  • Debian 8

  They do not work in Debian 7 (library mismatch). They may work in other systems, but that is untested.

  The script used is in the unix_packages directory. The Vagrantfiles for the various build systems are in the Vagrant directory.

Bug Fixes

• The only bug that can be called a bug is actually a stray .exe suffix in the binary package creation section (cx_freeze) of setup.py. The Windows binaries should have .exe extensions, but not unix variants.
• Elasticsearch 5.0.0-beta1 testing revealed that a document ID is required during document creation in tests. This has been fixed, and a redundant bit of code in the forcemerge integration test was removed.

Documentation

• The documentation has been updated and improved. Examples and installation are now top-level events, with the sub-sections each having their own link. They also now show how to install and use the binary packages, and the section on installation from source has been improved. The missing section on installing the voluptuous schema verification module has been written and included. #776 (untergeek)

4.1.1 (27 September 2016)

Bug Fixes

• String-based booleans are now properly coerced. This fixes an issue where True/False were used in environment variables, but not recognized. #765 (untergeek)
• Fix missing count method in __map_method in SnapshotList. Reported in #766 (untergeek)

General

• Update es_repo_mgr to use the same client/logging YAML config file. Requested in #752 (untergeek)

Schema Validation

• Cases where source was not defined in a filter (but should have been) were informing users that a timestring field was there that shouldn’t have been. This edge case has been corrected.

Documentation

• Added notifications and FAQ entry to explain that AWS ES is not supported.

4.1.0 (6 September 2016)

New Features

• Configuration and Action file schema validation. Requested in #674 (untergeek)
• Alias filtertype! With this filter, you can select indices based on whether they are part of an alias. Merged in #748 (untergeek)
• Count filtertype! With this filter, you can now configure Curator to only keep the most recent _n_ indices (or snapshots!). Merged in #749 (untergeek)
• Experimental! Use environment variables in your YAML configuration files. This was a popular request, #697. (untergeek)

General

• New requirement! voluptuous Python schema validation module
• Requirement version bump: Now requires elasticsearch-py 2.4.0

Bug Fixes

• delete_aliases option in close action no longer results in an error if not all selected indices have an alias. Add test to confirm expected behavior. Reported in #736 (untergeek)

Documentation

• Add information to FAQ regarding indices created before Elasticsearch 1.4. Merged in #747

4.0.6 (15 August 2016)

Bug Fixes

• Update old calls used with ES 1.x to reflect changes in 2.x+. This was necessary to work with Elasticsearch 5.0.0-alpha5. Fixed in #728 (untergeek)

Doc Fixes

• Add section detailing that the value of a value filter element should be encapsulated in single quotes. Reported in #726. (untergeek)

4.0.5 (3 August 2016)

Bug Fixes

• Fix incorrect variable name for AWS Region reported in #679 (basex)
• Fix filter_by_space() to not fail when index age metadata is not present. Indices without the appropriate age metadata will instead be excluded, with a debug-level message. Reported in #724 (untergeek)

Doc Fixes

• Fix documentation for the space filter and the source filter element.

4.0.4 (1 August 2016)

Bug Fixes

• Fix incorrect variable name in Allocation action. #706 (lukewaite)
• Incorrect error message in create_snapshot_body reported in #711 (untergeek)
• Test for empty index list object should happen in action initialization for snapshot action. Discovered in #711. (untergeek)

Doc Fixes

• Add menus to asciidoc chapters #704 (untergeek)
• Add pyyaml dependency #710 (dtrv)

4.0.3 (22 July 2016)

General

• 4.0.2 didn’t work for pip installs due to an omission in the MANIFEST.in file. This came up during release testing, but before the release was fully published. As the release was never fully published, this should not have actually affected anyone.

Bug Fixes

• These are the same as 4.0.2, but it was never fully released.
• All default settings are now values returned from functions instead of constants. This was resulting in settings getting stomped on. New test addresses the original complaint. This removes the need for deepcopy. See issue #687 (untergeek)
• Fix host vs. hosts issue in get_client() rather than the non-functional function in repomgrcli.py.
• Update versions being tested.
• Community contributed doc fixes.
• Reduced logging verbosity by making most messages debug level. #684 (untergeek)
• Fixed log whitelist behavior (and switched to blacklisting instead). Default behavior will now filter traffic from the elasticsearch and urllib3 modules.
• Fix Travis CI testing to accept some skipped tests, as needed. #695 (untergeek)
• Fix missing empty index test in snapshot action. #682 (sherzberg)

4.0.2 (22 July 2016)

Bug Fixes

• All default settings are now values returned from functions instead of constants. This was resulting in settings getting stomped on. New test addresses the original complaint. This removes the need for deepcopy. See issue #687 (untergeek)
• Fix host vs. hosts issue in get_client() rather than the non-functional function in repomgrcli.py.
• Update versions being tested.
• Community contributed doc fixes.
• Reduced logging verbosity by making most messages debug level. #684 (untergeek)
• Fixed log whitelist behavior (and switched to blacklisting instead). Default behavior will now filter traffic from the elasticsearch and urllib3 modules.
• Fix Travis CI testing to accept some skipped tests, as needed. #695 (untergeek)
• Fix missing empty index test in snapshot action. #682 (sherzberg)

4.0.1 (1 July 2016)

Bug Fixes

• Coerce Logstash/JSON logformat type timestamp value to always use UTC. #661 (untergeek)
• Catch and remove indices from the actionable list if they do not have a creation_date field in settings. This field was introduced in ES v1.4, so that indicates a rather old index. #663 (untergeek)
• Replace missing state filter for snapshotlist. #665 (untergeek)
• Restore es_repo_mgr as a stopgap until other CLI scripts are added. It will remain undocumented for now, as I am debating whether to make repository creation its own action in the API. #668 (untergeek)
• Fix dry run results for snapshot action. #673 (untergeek)

4.0.0 (24 June 2016)

It’s official! Curator 4.0.0 is released!

Breaking Changes

• New and improved API!

• Command-line changes. No more command-line args, except for --config, --actions, and --dry-run:

  • --config points to a YAML client and logging configuration file. The default location is ~/.curator/curator.yml
  • --actions arg points to a YAML action configuration file
  • --dry-run will simulate the action(s) which would have taken place, but not actually make any changes to the cluster or its indices.

New Features

• Snapshot restore is here!
• YAML configuration files. Now a single file can define an entire batch of commands, each with their own filters, to be performed in sequence.
• Sort by index age not only by index name (as with previous versions of Curator), but also by index creation_date, or by calculations from the Field Stats API on a timestamp field.
• Atomically add/remove indices from aliases! This is possible by way of the new IndexList class and YAML configuration files.
• State of indices pulled and stored in IndexList instance. Fewer API calls required to serially test for open/close, size_in_bytes, etc.
• Filter by space now allows sorting by age!
• Experimental! Use AWS IAM credentials to sign requests to Elasticsearch. This requires the end user to manually install the requests_aws4auth python module.
• Optionally delete aliases from indices before closing.
• An empty index or snapshot list no longer results in an error if you set ignore_empty_list to True. If True it will still log that the action was not performed, but will continue to the next action. If ‘False’ it will log an ERROR and exit with code 1.

API

• Updated API documentation
• Class: IndexList. This pulls all indices at instantiation, and you apply filters, which are class methods. You can iterate over as many filters as you like, in fact, due to the YAML config file.
• Class: SnapshotList. This pulls all snapshots from the given repository at instantiation, and you apply filters, which are class methods. You can iterate over as many filters as you like, in fact, due to the YAML config file.
• Add wait_for_completion to Allocation and Replicas actions. These will use the client timeout, as set by default or timeout_override, to determine how long to wait for timeout. These are handled in batches of indices for now.
• Allow timeout_override option for all actions. This allows for different timeout values per action.
• Improve API by giving each action its own do_dry_run() method.

General

• Updated use documentation for Elastic main site.
• Include example files for --config and --actions.

4.0.0b2 (16 June 2016)

Second beta release of the 4.0 branch

New Feature

• An empty index or snapshot list no longer results in an error if you set ignore_empty_list to True. If True it will still log that the action was not performed, but will continue to the next action. If ‘False’ it will log an ERROR and exit with code 1. (untergeek)

4.0.0b1 (13 June 2016)

• Atomically add/remove indices from aliases! This is possible by way of the new IndexList class and YAML configuration files.
• State of indices pulled and stored in IndexList instance. Fewer API calls required to serially test for open/close, size_in_bytes, etc.
• Filter by space now allows sorting by age!
• Experimental! Use AWS IAM credentials to sign requests to Elasticsearch. This requires the end user to manually install the requests_aws4auth python module.

• Fix a doc inconsistency #509 (pmoust)
• Fix a typo in show documentation #513 (pbamba)
• Default to trying the cluster state for checking whether indices are closed, and then fall back to using the _cat API (for Amazon ES instances). #519 (untergeek)
• Improve logging to show time delay between optimize runs, if selected. #525 (untergeek)
• Allow elasticsearch-py module versions through 2.3.0 (a presumption at this point) #524 (untergeek)
• Improve logging in snapshot api method to reveal when a repository appears to be missing. Reported in #551 (untergeek)
• Test that --timestring has the correct variable for --time-unit. Reported in #544 (untergeek)
• Allocation will exit with exit_code 0 now when there are no indices to work on. Reported in #531 (untergeek)

3.4.0 (28 October 2015)

General

• API change in elasticsearch-py 1.7.0 prevented alias operations. Fixed in #486 (HonzaKral)
• During index selection you can now select only closed indices with --closed-only. Does not impact --all-indices Reported in #476. Fixed in #487 (Basster)
• API Changes in Elasticsearch 2.0.0 required some refactoring. All tests pass for ES versions 1.0.3 through 2.0.0-rc1. Fixed in #488 (untergeek)
• es_repo_mgr now has access to the same SSL options from #462. #489 (untergeek)

3.3.0 (31 August 2015)

Announcement

• Curator is tested in Jenkins. Each commit to the master branch is tested with both Python versions 2.7.6 and 3.4.0 against each of the following Elasticsearch versions: * 1.7_nightly * 1.6_nightly * 1.7.0 * 1.6.1 * 1.5.1 * 1.4.4 * 1.3.9 * 1.2.4 * 1.1.2 * 1.0.3
• If you are using a version different from this, your results may vary.

General

• Allocation type can now also be include or exclude, in addition to the the existing default require type. Add --type to the allocation command to specify the type. #443 (steffo)
• Bump elasticsearch python module dependency to 1.6.0+ to enable synced_flush API call. Reported in #447 (untergeek)
• Add SSL features, --ssl-no-validate and certificate to provide other ways to validate SSL connections to Elasticsearch. #436 (untergeek)

Bug fixes

• Delete by space was only reporting space used by primary shards. Fixed to show all space consumed. Reported in #455 (untergeek)
• Update exit codes and messages for snapshot selection. Reported in #452 (untergeek)
• Fix potential int/float casting issues. Reported in #465 (untergeek)

3.2.3 (16 July 2015)

Bug fix

• In order to address customer and community issues with bulk deletes, the master_timeout is now invoked for delete operations. This should address 503s with 30s timeouts in the debug log, even when --timeout is set to a much higher value. The master_timeout is tied to the --timeout flag value, but will not exceed 300 seconds. #420 (untergeek)

General

• Mixing it up a bit here by putting General second! The only other changes are that logging has been improved for deletes so you won’t need to have the --debug flag to see if you have error codes >= 400, and some code documentation improvements.

3.2.2 (13 July 2015)

General

• This is a very minor change. The mock library recently removed support for Python 2.6. As many Curator users are using RHEL/CentOS 6, which is pinned to Python 2.6, this requires the mock version referenced by Curator to also be pinned to a supported version (mock==1.0.1).

3.2.1 (10 July 2015)

General

• Added delete verification & retry (fixed at 3x) to potentially cover an edge case in #420 (untergeek)
• Since GitHub allows rST (reStructuredText) README documents, and that’s what PyPI wants also, the README has been rebuilt in rST. (untergeek)

Bug fixes

• If closing indices with ES 1.6+, and all indices are closed, ensure that the seal command does not try to seal all indices. Reported in #426 (untergeek)
• Capture AttributeError when sealing indices if a non-TransportError occurs. Reported in #429 (untergeek)

3.2.0 (25 June 2015)

New!

• Added support to manually seal, or perform a [synced flush](http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-synced-flush.html) on indices with the seal command. #394 (untergeek)
• Added experimental support for SSL certificate validation. In order for this to work, you must install the certifi python module: pip install certifi This feature should automatically work if the certifi module is installed. Please report any issues.

General

• Changed logging to go to stdout rather than stderr. Reopened #121 and figured they were right. This is better. (untergeek)
• Exit code 99 was unpopular. It has been removed. Reported in #371 and #391 (untergeek)
• Add --skip-repo-validation flag for snapshots. Do not validate write access to repository on all cluster nodes before proceeding. Useful for shared filesystems where intermittent timeouts can affect validation, but won’t likely affect snapshot success. Requested in #396 (untergeek)
• An alias no longer needs to be pre-existent in order to use the alias command. #317 (untergeek)
• es_repo_mgr now passes through upstream errors in the event a repository fails to be created. Requested in #405 (untergeek)

Bug fixes

• In rare cases, * wildcard would not expand. Replaced with _all. Reported in #399 (untergeek)
• Beginning with Elasticsearch 1.6, closed indices cannot have their replica count altered. Attempting to do so results in this error: org.elasticsearch.ElasticsearchIllegalArgumentException: Can't update [index.number_of_replicas] on closed indices [[test_index]] - can leave index in an unopenable state As a result, the change_replicas method has been updated to prune closed indices. This change will apply to all versions of Elasticsearch. Reported in #400 (untergeek)
• Fixed es_repo_mgr repository creation verification error. Reported in #389 (untergeek)

3.1.0 (21 May 2015)

General

• If wait_for_completion is true, snapshot success is now tested and logged. Reported in #253 (untergeek)
• Log & return false if a snapshot is already in progress (untergeek)
• Logs individual deletes per index, even though they happen in batch mode. Also log individual snapshot deletions. Reported in #372 (untergeek)
• Moved chunk_index_list from cli to api utils as it’s now also used by filter.py
• Added a warning and 10 second timer countdown if you use --timestring to filter indices, but do not use --older-than or --newer-than in conjunction with it. This is to address #348, which behavior isn’t a bug, but prevents accidental action against all of your time-series indices. The warning and timer are not displayed for show and --dry-run operations.
• Added tests for es_repo_mgr in #350
• Doc fixes

Bug fixes

• delete-by-space needed the same fix used for #245. Fixed in #353 (untergeek)
• Increase default client timeout for es_repo_mgr as node discovery and availability checks for S3 repositories can take a bit. Fixed in #352 (untergeek)
• If an index is closed, indicate in show and --dry-run output. Reported in #327. (untergeek)
• Fix issue where CLI parameters were not being passed to the es_repo_mgr create sub-command. Reported in #337. (feltnerm)

3.0.3 (27 Mar 2015)

Announcement

This is a bug fix release. #319 and #320 are affecting a few users, so this release is being expedited.

Test count: 228 Code coverage: 99%

General

• Documentation for the CLI converted to Asciidoc and moved to http://www.elastic.co/guide/en/elasticsearch/client/curator/current/index.html
• Improved logging, and refactored a few methods to help with this.
• Dry-run output is now more like v2, with the index or snapshot in the log line, along with the command. Several tests needed refactoring with this change, along with a bit of documentation.

Bug fixes

• Fix links to repository in setup.py. Reported in #318 (untergeek)
• No more --delay with optimized indices. Reported in #319 (untergeek)
• --request_timeout not working as expected. Reinstate the version 2 timeout override feature to prevent default timeouts for optimize and snapshot operations. Reported in #320 (untergeek)
• Reduce index count to 200 for test.integration.test_cli_commands.TestCLISnapshot.test_cli_snapshot_huge_list in order to reduce or eliminate Jenkins CI test timeouts. Reported in #324 (untergeek)
• --dry-run no longer calls show, but will show output in the log, as in v2. This was a recurring complaint. See #328 (untergeek)

3.0.2 (23 Mar 2015)

Announcement

This is a bug fix release. #307 and #309 were big enough to warrant an expedited release.

Bug fixes

• Purge unneeded constants, and clean up config options for snapshot. Reported in #303 (untergeek)
• Don’t split large index list if performing snapshots. Reported in #307 (untergeek)
• Act correctly if a zero value for –older-than or –newer-than is provided. #309 (untergeek)

3.0.1 (16 Mar 2015)

Announcement

The regex_iterate method was horribly named. It has been renamed to apply_filter. Methods have been added to allow API users to build a filtered list of indices similarly to how the CLI does. This was an oversight. Props to @SegFaultAX for pointing this out.

General

• In conjunction with the rebrand to Elastic, URLs and documentation were updated.
• Renamed horribly named regex_iterate method to apply_filter #298 (untergeek)
• Added build_filter method to mimic CLI calls. #298 (untergeek)
• Added Examples page in the API documentation. #298 (untergeek)

Bug fixes

• Refactored to show –dry-run info for –disk-space calls. Reported in #290 (untergeek)
• Added list chunking so acting on huge lists of indices won’t result in a URL bigger than 4096 bytes (Elasticsearch’s default limit.) Reported in https://github.com/elastic/curator/issues/245#issuecomment-77916081
• Refactored to_csv() method to be simpler.
• Added and removed tests according to changes. Code coverage still at 99%

3.0.0 (9 March 2015)

Release Notes

The full release of Curator 3.0 is out! Check out all of the changes here!

Note: This release is _not_ reverse compatible with any previous version.

Because 3.0 is a major point release, there have been some major changes to both the API as well as the CLI arguments and structure.

Be sure to read the updated command-line specific docs in the [wiki](https://github.com/elasticsearch/curator/wiki) and change your command-line arguments accordingly.

The API docs are still at http://curator.readthedocs.io. Be sure to read the latest docs, or select the docs for 3.0.0.

General

• Breaking changes to the API. Because this is a major point revision, changes to the API have been made which are non-reverse compatible. Before upgrading, be sure to update your scripts and test them thoroughly.
• Python 3 support Somewhere along the line, Curator would no longer work with curator. All tests now pass for both Python2 and Python3, with 99% code coverage in both environments.
• New CLI library. Using Click now. http://click.pocoo.org/3/ This change is especially important as it allows very easy CLI integration testing.
• Pipelined filtering! You can now use --older-than & --newer-than in the same command! You can also provide your own regex via the --regex parameter. You can use multiple instances of the --exclude flag.
• Manually include indices! With the --index paramter, you can add an index to the working list. You can provide multiple instances of the --index parameter as well!
• Tests! So many tests now. Test coverage of the API methods is at 100% now, and at 99% for the CLI methods. This doesn’t mean that all of the tests are perfect, or that I haven’t missed some scenarios. It does mean, however, that it will be much easier to write tests if something turns up missed. It also means that any new functionality will now need to have tests.
• Iteration changes Methods now only iterate through each index when appropriate! In fact, the only commands that iterate are alias and optimize. The bloom command will iterate, but only if you have added the –delay flag with a value greater than zero.
• Improved packaging! Methods have been moved into categories of api and cli, and further broken out into individual modules to help them be easier to find and read.
• Check for allocation before potentially re-applying an allocation rule. #273 (ferki)
• Assigning replica count and routing allocation rules _can_ be done to closed indices. #283 (ferki)

Bug fixes

• Don’t accidentally delete .kibana index. #261 (malagoli)
• Fix segment count for empty indices. #265 (untergeek)
• Change bloom filter cutoff Elasticsearch version to 1.4. Reported in #267 (untergeek)

3.0.0rc1 (5 March 2015)

Release Notes

RC1 is here! I’m re-releasing the Changes from all betas here, minus the intra-beta code fixes. Barring any show stoppers, the official release will be soon.

General

• Breaking changes to the API. Because this is a major point revision, changes to the API have been made which are non-reverse compatible. Before upgrading, be sure to update your scripts and test them thoroughly.

3.0.0b4 (5 March 2015)

Notes

Integration testing! Because I finally figured out how to use the Click Testing API, I now have a good collection of command-line simulations, complete with a real back-end. This testing found a few bugs (this is why testing exists, right?), and fixed a few of them.

Bug fixes

• HUGE! curator show snapshots would _delete_ snapshots. This is fixed.
• Return values are now being sent from the commands.
• scripttest is no longer necessary (click.Test works!)
• Calling get_snapshot without a snapshot name returns all snapshots

3.0.0b3 (4 March 2015)

Bug fixes

• setup.py was lacking the new packages “curator.api” and “curator.cli” The package works now.
• Python3 suggested I had to normalize the beta tag to just b3, so that’s also changed.
• Cleaned out superfluous imports and logger references from the __init__.py files.

3.0.0-beta2 (3 March 2015)

Bug fixes

• Python3 issues resolved. Tests now pass on both Python2 and Python3

• Tests! So many tests now. Unit test coverage of the API methods is at 100% now. This doesn’t mean that all of the tests are perfect, or that I haven’t missed some scenarios. It does mean that any new functionality will need to also have tests, now.
• Methods now only iterate through each index when appropriate!
• Improved packaging! Hopefully the entry_point issues some users have had will be addressed by this. Methods have been moved into categories of api and cli, and further broken out into individual modules to help them be easier to find and read.
