3.1.0

PuppetDB 3.1.0 is a backward-compatible feature release that includes new aggregate operators and a new admin route that improves import/export performance.

Enhancements

• Added an admin route for importing/exporting PuppetDB data. Previously import/export worked by issuing GET/POST requests for each report/catalog/factset for a given node. This endpoint allows a POST or GET of a tarball containing all of the data to be imported or exported. This significantly improves import/export performance. (PDB-1631)

• Added support for sum, average, minimum and maximum operators to the PuppetDB query language (PDB-1440)

• Added a new report wire-format that submits data to PuppetDB in a more resource-centric manner. Previously, resource and event data was munged together into a new object type before being sent to PuppetDB. With this change the data is sent in a format similar to Puppet's internal representation of the data.

• Added an experimental command parameter "secondsToWaitForCompletion" that allows command POSTs to block up to a specified number of seconds waiting for the command to be successfuly stored.

• Added realistically spaced timestamps and transaction_uuids to commands generated by the benchmark tool. Previously the same time and transaction_uuid was used for all submitted commands.

Code Maintenance and Related Changes

• Upgrade to clojure.java.jdbc 0.3.7 (PDB-1739)

• Switched to the Puppet Labs version-checking library (PDB-1823)

• Cache database metadata on startup. Previously code involving query features that were different between HyperSQL and PostgreSQL would require a database connection to determine the correct SQL to be generated. This changes that code to acquire this database metadata on startup and cache it. (PDB-1737)

3.0.2

PuppetDB 3.0.2 is a bugfix release to address performance issues with the aggregate-event-count and fact-paths endpoints as well as memory starvation involving structured-facts.

Bug Fixes and Maintenance

• Previously PuppetDB cached prepared statements for SQL queries. This caused memory starvation involving structured-facts where large structured-facts would create a new prepared statement object for each update. The large objects would accumulate in the cache due to the non-zero cache size. This release addresses this issue in two ways, by disabling the cache and changing the structured-facts update queries to be more efficient. (PDB-1721)

• Given a large number of nodes and reports, consumers of the aggregate-event-counts endpoint were experiencing slow response times. These performance issues have have been addressed in this release. One notable outcome from these fixes is that the endpoint no longer requires a query parameter. (PDB-1809)

• Some PuppetDB tables were never analyzed by the autovacuum analyzer which led to performance issues with the fact-paths endpoint. This release adds code to perform the analyze whenever PuppetDB schema are updated. (PDB-1812)

• This release fixes an issue where the max-frame-size parameter was being ignored by consumers of the command queue, causing large commands to produce stacktraces in the PuppetDB log. (PDB-1812)

3.0.1

PuppetDB 3.0.1 is a bugfix release to fix packaging problems in PuppetDB 3.0.0 for RPM-based systems.

Bug Fixes and Maintenance

• As part of the PuppetDB 3.0.0 release, the puppetdb-terminus package was renamed to puppetdb-termini for consistency with other Puppet Labs products. A flawed dependency in the puppetdb-termini package prevented installation of the older 2.3.x puppetdb-terminus package on RPM-based platforms. This release fixes that dependency, allowing the older version to be installed. (PDB-1760)

  To fully correct the problem, the existing 3.0.0 puppetdb and puppetdb-termini packages will be removed from the Puppet Collection 1 yum repository. The new 3.0.1 packages will take their place.

• The 2.x->3.x migration script now only runs on upgrades from 2.x versions of PuppetDB. (PDB-1763)

3.0.0

PuppetDB 3.0.0 is a major release which introduces some major new features, with some breaking changes.

Upgrading

• This version of PuppetDB adopts the AIO layout to be consistent with other Puppet Labs layouts, such as Puppet Server. We recommend the using the PuppetDB Puppet Module version 5, as it will automate a lot of this kind of management and has been modified specifically for PuppetDB 3 support by default.

  For those that don't use the PuppetDB module, this means the following paths have changed:

  • Primary configuration: /etc/puppetdb is now /etc/puppetlabs/puppetdb
  • Logs: /var/log/puppetdb is now /var/log/puppetlabs/puppetdb
  • Binaries: /usr/bin is now /opt/puppetlabs/bin
  • Data: /var/lib/puppetdb is now /opt/puppetlabs/server/data/puppetdb
  • Rundir: /var/run/puppetdb is now /var/run/puppetlabs/puppetdb

  During upgrade we have written a script that will migrate your configuration to the new locations. After upgrade you should double check the migrated configuration to ensure everything is correct.

• PuppetDB now only supports PostgreSQL 9.4 and newer. Support for versions prior to 9.4 have been retired. Users must upgrade PostgreSQL to 9.4 or newer before upgrading PuppetDB. Users should also enable the pg_trgm extension, as explained here. The official PostgreSQL repositories are recommended for packaging, see the (YUM) instructions or the (APT) instructions for more details.

• At the moment, PuppetDB 3 only supports Puppet 4 or higher. We are investigating packaging changes necessary to support Puppet 3 users. For now you must have installed Puppet 4 from Puppet Collections 1 before installing PuppetDB 3.

• Before upgrading, make sure that all of your PuppetDB instances are shut down, and only upgrade one at a time.

• The puppetdb-terminus package has now been renamed to puppetdb-termini. Make sure to upgrade your puppetdb-terminus package to the puppetdb-termini package (on the host where your Puppet Master lives), and restart your master service (this is typically called puppetserver).

• Before upgrading you should ensure you have as much free disk space as you have data. Database schema changes (also known as migrations) in this release often require temporary duplication of table data and may mean you have wait during the upgrade as these migrations run.

• After the upgrade, you may notice some additional system load for the first 30 to 60 minutes. This is due to internal changes in the way we check if objects (such as catalogs) are up-to-date.

• Users manually upgrading PuppetDB should restart both Puppet server and PuppetDB after the upgrade. This has been automated for version 5 users of the PuppetDB Puppet Module.

Downgrading

• If you attempt to downgrade to a previous version of PuppetDB, in addition to wiping the database, you will need to clear the queue directory as described in the documentation on KahaDB corruption. Otherwise you might see an IOException during startup when the older PuppetDB (using an older version of KahaDB) tries to read leftover, incompatible queue data.

Breaking Changes

This release retires all API versions before v4 and promotes v4 to be the stable API. The following changes have been made since the last stable release of PuppetDB, which included an experimental v4 API.

• Versions 2 and 3 of the query API are now retired. There are also significant differences between the current stable v4 and the previously experimental v4.

  Full documentation outlining this change is available in the API upgrading guide.

• We've retired some previously deprecated commands (PDB-840)

  The currently supported commands and versions are:

  • replace catalog, v6
  • replace facts, v4
  • deactivate node, v3
  • store report, v5

  Older versions of the commands on your queue will still be processed by PuppetDB so you won't lose the data from messages still being processed by PuppetDB before an upgrade.

• All query parameters, query responses and command wire formats use underscores instead of dashes. (PDB-698)

  This patch changes all incoming and outgoing JSON to use underscores instead of dashes, which will make it easier to interface with PDB using languages like javascript and python. Query parameters also user underscores to be consistent with the response formats. Consult the API docs for the exact new parameters if you are uncertain.

• Split the command endpoint (/v3/commands or /v4/commands) into a separate API, mounted at /pdb/cmd/v1 so it can be versioned and managed separately. (PDB-1534) (PDB-1561)

• /metrics has been moved to it's own service, mounted at /metrics/v1 (PDB-800)

  This change will allow us to version the metrics service independently from the query service, and clears the way for future incorporation with other PL products.

• Version and server-time are now mounted under the metadata API (PDB-1562)

  These endpoints now live in /pdb/meta/v1.

• Change name key to certname across our API (PDB-1099)

  For clarity and consistency across endpoints, the name key has been changed to certname where appropriate. This affects queries to and responses from the /pdb/query/v4/catalogs and /pdb/query/v4/nodes endpoint. The replace catalog and replace facts commands have also been changed.

• Response data for related entities (i.e. resources in a catalog response) is now more formalized. (PDB-1228)

  This change pertains to entities that are contained within other entities in the JSON response of our query APIs. Some examples of these nested entities are resources and edges in catalogs or the new metrics and logs fields that are included in the reports response. In the past version of the API (including the experimental /v4 version) this nested data was returned directly:

  { "certname" : "yo.delivery.puppetlabs.net", "version" : "e4c339f", "transaction-uuid" : "53b72442-3b73-11e3-94a8-1b34ef7fdc95", "environment" : "production", "edges" : [{"source": {"type": "package", "title": "openssh-server"} "target": {"type": "file", "title": "/etc/ssh/sshd_config"} "relationship": "before"}], ... }

  This will now be nested with an href and the entity included as the value of the "data" key:

  { "certname" : "yo.delivery.puppetlabs.net", "version" : "e4c339f", "transaction-uuid" : "53b72442-3b73-11e3-94a8-1b34ef7fdc95", "environment" : "production", "edges" : {"href": "/pdb/query/v4/catalogs/yo.delivery.puppetlabs.net/edges", "data": [{"source": {"type": "package", "title": "openssh-server"} "target": {"type": "file", "title": "/etc/ssh/sshd_config"} "relationship": "before"}], ... }

  Note that HSQLDB users will not have the data keys prepopulated and will need to follow the href included in the response to get the nested entity data. PostgreSQL users will always have the nested entity included.

  The cause of this change is a new feature (json aggregation) in PostgreSQL that allows us to improve the performance of queries that contain this nested entity data. HSQLDB does not have an analogous feature, which required us to formalize how this nested entity data is returned.

  For PostgreSQL consumers this means the extra data key needs to be traversed to access the related object data.

• Add a noop flag to reports (PDB-1177)

  This adds a noop field to the reports object, which is a required boolean flag indicating whether the run producing the report used --noop (for example: puppet agent -t --noop).

• Remove com. prefix from JMX MBeans and the ActiveMQ destination name (PDB-863)

  The com. prefix has been removed from the JMX MBeans and the ActiveMQ destination name. They are now in the puppetlabs.puppetdb namespace. Any monitoring applications you have that expect the old namespace will need to be changed. This pertains to JMX MBeans accessed via JMX and via our HTTP based endpoints.

• The endpoints aggregate-event-counts and event-counts have been marked as experimental.

  These endpoints were introduced to solve specific problems for the PE console, however the design is under question. We're moving these endpoints back to experimental status so that we are able to deliver a better option later on. As per our versioning policy, this implies that breaking changes may be made outside of a major release boundary.

• The older puppetdb-* sub-commands are now retired (puppetdb-ssl-setup for example) instead, the new sub-command style should be used puppetdb ssl-setup. (PDB_663)

• Retire support for PostgreSQL versions less than 9.4 (PDB-1592)

• Retire support for RedHat 5, Debian 6 & Ubuntu 10.04 (PDB-663)

• Retire [global] configuration key event-query-limit (PDB-693)

• Retire [database] configuration key node-ttl-days (PDB-644)

• Retire [jetty] configuration key certificate-whitelist (PDB-886)

  Moved [jetty] configuration key certificate-whitelist to the [puppetdb] section.

• PuppetDB now has a new filesystem layout that complies with the Puppet AIO layout (PDB-1455)

• PuppetDB now uses the Ezbake build system which changes the way we package (PDB-663)

• Due to the Ezbake changes, the [repl] block has been renamed to [nrepl] and type is no longer an accepted parameter (PDB-663)

• The endpoints contained in /experimental have now been removed (PDB-1127)

• Return proper 404 errors for shorthand endpoints whose parents do not exist. Previously this returned an empty list. A shorthand endpoint is a convenient way to filter one entity's response using another entity. A good example of this kind of endpoint is using the nodes endpoint to get the facts associated with that node i.e. /pdb/query/v4/nodes/foo.com/facts (PDB-1473)

• To improve performance on the aggregate-event-counts endpoint, we've modified the API and underlying storage indexing. We've also dropped HSQLDB support for this endpoint. (PDB-1587)

Deprecations

• HyperSQL is now deprecated and will be removed in the next major release (PDB-1508)

  Installing via the package will no longer default to using HyperSQL. Instead now we expect PostgreSQL by default, and will return an error if it hasn't been configured.

New Features

• We now store report metrics (PDB-1192)

• We now store report logs (PDB-1192)

• We have added count aggregation and group_by capabilities to the query API (PDB-1181)

• Support extract as a top level query operator (PDB-207)

  This provides support for requesting only the fields that you need in an API response when querying data.

• Support fallback PuppetDB connections (PDB-100)

  When configuring your connection to PuppetDB, you can now specify a fallback. Instead of the now deprecated server and port config, you can use a server\_urls config that contains the full path to one or more PuppetDB URLs. The old server/port format is still supported.

  This commit also supports a new server\_url\_timeout config. If the PuppetDB instance has not responded in the specified number of seconds (defaults to 30) it will fail and roll to the next PuppetDB url (if one is provided).

• Support for hyphenated classnames, supported by Puppet 2.7.x - 3.7.x. (PDB-1024)

• Support for -v or --version flag to the CLI to get the PuppetDB version. (PDB-992)

• The reports endpoint now implements the latest_report? query, which filters the response to only include reports that are from the latest puppet run for each node. (PDB-1244)

• Support for querying edges directly. Previously edges were only returned as part of a catalog. You can also query edges specific to a particular catalog using the new edges suffix on the catalogs endpoint. (PDB-1228).

• Support for passing in an export archive to the load testing tool (PDB-1249)

• Now the default behavior for benchmark is to use some supplied sample data, to lower the barrier for entry for the tooling (PDB-1249)

• Support for querying a particular node's factset via the child endpoint /factsets/<node>. (PDB-1599)

• Support for Apache-style access logging to PuppetDB packages, enabled by default (PDB-477)

  Now you can see individual requests logged by the PuppetDB application itself, instead of requiring a proxy to do this for you.

• Support for disabling update checking via the [puppetdb] disable-update-checking configuration key (PDB-158)

  The value defaults to false; see the configuration documentation for more details.

API changes

• The query parameter for /pdb/query/v4/events is now optional (PDB-1132)

• Made /pdb/query/v4/catalogs queryable (PDB-1028)

• Added producer\_timestamp field to factsets and catalogs (PDB-489)

  On factsets the field is queryable and orderable.

• Added producer\_timestamp field to reports (PDB-1487)

• Added resource\_events key to the store report command (PDB-1072)

  API responses can now be easily used for resubmission as a report. This will be helpful in the HA context, where it will reduce the number of requests needed to synchronize reports.

• The command deactivate node now requires a producer_timestamp field (PDB-1310)

Performance

• Switch from text based storage of UUID and hashes, to the PostgreSQL uuid and bytea types respectively (PDB-1416)

• The reports database table was using the hash string as its primary key. We have switched to using a smaller bigint primary key for that table. This will result in faster joins and smaller foreign key indexes sizes for tables relating to reports. (PDB-1218)

• We have dropped the latest\_reports table in favor of storing a reference to the latest report of each certname in the certnames table. (PDB-1254)

Bug Fixes and Maintenance

• Upgrade to Clojure 1.7.0 from 1.6.0 (PDB-1703)

• Improve whitelist failure message (PDB-1003)

• Normalize resource event timestamps before storage (PDB-1241)

• Add tags to catalog hash (PDB-332)

• Improve handling of invalid queries (PDB-950)

• Remove timestamps from factset hash calculation (PDB-1199)

• Upgrade to latest trapperkeeper (PDB-1095)

• Warn user with unknown config items (PDB-1067)

• We now use honeysql to generate SQL (PDB-1228)

• Fixed a bug in extract with 2 element expressions (PDB-1064)

  Previously the query engine would fail if a top-level extract's expression had only two elements (i.e. ["not" ["=" "certname" "foo.com]]). This commit adds a guard to the extracts used for nested queries to ensure it doesn't catch the two clause version of top-level extract.

• Add validation for top-level extract fields. (PDB-1043)

• Add validation for in/extract fields in that are passed in vector form. (PDB-722)

• Remove puts statements from PuppetDB terminus (PDB-1020)

• Retire facts.strip\_internal (terminus) (PDB-971)

  This patch adds a maybe_strip_internal method to Puppet::Node::Facts::Puppetdb that will call Facts#strip_internal if the method exists, but Facts#values if not. This will allow our terminus to remain backwards compatible when Puppet retires the strip_internal method and the timestamp fact.

• Allow factset hashes to be nil in db

  This is necessary for factsets to function after the (PDB-898) migration, since existing factsets are not being hashed.

• Fix ActiveMQ errors on PDB shutdown (PDB-880) (PDB-1102)

  We upgraded ActiveMQ to 5.7.0 (later we upgraded to 5.11.1). The upgrade to 5.7.0 fixed two errors that sometimes occur at shutdown. The first was related to the broker stopping before its consumers were removed. The other was related to KahaDB failing to reset due to the PageFile not being loaded. Upgrading fixed these failures.

• Refresh service configuration on package upgrades (PDB-917)

  Previously, upgrades were not properly refreshing the service information. This adds a conditional restart on upgrades.

• Update rpm spec and systemd service file for pidfile handling

  Previously, the rpm package was creating /var/run/puppetdb at install time for pidfile storage. This will break on modern Fedora/RHEL and SUSE systems as /var/run (which is a symlink to /run) uses tmpfs and will not persist through a reboot.

  As the systemd service type is "simple", meaning non-forking, systemd manages the process directly, and the PIDfile is not needed or used on those platforms.

• Update metrics on PDB start (PDB-653)

  Previously the DLO metrics only updated on a failed command submission, which meant restarting PDB would blank the metrics until the next failure. This patch initializes DLO metrics on PDB startup if the DLO directory, which is created on first failure, already exists.

• Add thread names to logging (PDB-855)

  Add thread names to the various logback.xml configuration files in this project. This provides us with better traceability when attempting to understand where a log message came from.

• Add better validation to benchmark tool for --runinterval and --numhosts (PDB-1268)

• Upgrade clj-time, compojure and ring-core to later revisions (PDB-1460)

• Update me.raynes/fs to 1.4.5 (PDB-1606)

• Improve the error message returned for the distinct_resources parameter on the aggregate-event-counts endpoint (PDB-1391)

• Refactored http streaming code (PDB-1465)

• Reject comparison queries with non-numerics on the /facts endpoint (PDB-1453)

• Consider reports as part of node expiration, and don't expire nodes that have had a report since the currently configured node-ttl (PDB-1638)

• Compute and store a hash of the factset for replace facts commands (PDB-898)

  This commit associates a hash of each factset with the metadata of the factset to allow us to easily tell if fact values have changed.

• Remove clamq wrapper for handling ActiveMQ internally, replacing it with our own (PDB-1252)

• Shutdown connection pooling properly when shutting down the service. (PDB-1348)

• Garbage collection routines now use producer_timestamp for determining deactivation status (PDB-1289)

• Added pagination to service query method (PDB-1071)

  Add a paging_options argument to the service query method.

Documentation Updates

• Add documentation on terminus failover support (PDB-486)

• Document the web-router-service (PDB-1070)

• Update operators doc link for PostgreSQL 9.3 (PDB-775)

• Add docs for new CRL and cert-chain TK features (PDB-347)

• Fix the replace-facts commands API examples (PDB-859)

• Include the navigation sidebar inside the puppetdb repo (PDB-1319)

2.3.7

PuppetDB 2.3.7 is a backwards-compatible bugfix release to resolve an issue with ActiveMQ configuration.

Upgrading

• For the best-possible performance and scaling capacity, we recommend PostgreSQL version 9.4 or newer with the pg_trgm extension enabled, as explained here. We have officially deprecated versions prior to 9.4. HSQLDB is only recommended for local development because it has a number of scaling and operational issues.

• Make sure that all of your PuppetDB instances are shut down, and only upgrade one at a time.

• Make sure to upgrade your puppetdb-terminus package (on the host where your Puppet master lives), and restart your master service.

Contributors

Bug Fixes and Maintenance

• The max-frame-size setting is now applied to the ActiveMQ consumer thread. It was previously set to the default, which could case errors when extremely large commands were submitted. (PDB-700)

2.3.6

PuppetDB 2.3.6 is a backwards-compatible bugfix release to introduce deprecation warnings for PostgreSQL versions less than 9.4. It also fixes a bug in the ssl-setup script that would complicate downgrades from 3.0, and a bug where the PuppetDB terminus would reject resource relationships on aliases.

Changes

Bug Fixes and Maintenance

• We have fixed a bug that caused PuppetDB to reject resource relationship titles containing newlines. (PDB-1529)

• We have removed an extraneous dependency on rubygem-json, which was preventing the PuppetDB terminus from installing with the all in one agent on RHEL 6. (PDB-1469)

• We have fixed a bug that caused unneccessary contention on the certnames table during command submission, which in turn caused commands to be retried more often than necessary. (PDB-1550)

• We have added additional error handling around PuppetDB startup failures that can be caused by server downgrades that implicitly downgrade ActiveMQ. (PDB-1454)

Testing

• We have updated our acceptance tests to run against Puppet 4 with AIO in addition to Puppet 3. (PDB-1300)

2.3.4

PuppetDB 2.3.4 is a backwards-compatible bugfix release that addresses an issue that would prevent fact storage for nodes under certain circumstances.

Upgrading

• For the best-possible performance and scaling capacity, we recommend PostgreSQL version 9.4 or newer with the pg_trgm extension enabled, as explained here, and we have officially deprecated versions earlier than 9.2.

• We have fixed a streaming issue with our facts response, so facts queries will not consume as much memory. (PDB-1470)

• We no longer log failures to connect to the puppetlabs update service at the info level. (PDB-1428)

• We have removed Ubuntu 10.04 and Fedora 19 from our build targets as they are end of life and no longer supported by Puppet Labs. (PDB-1449)

• We have upgraded to the latest version of prismatic/schema. (PDB-1432)

• We have upgraded to the latest versions of and trapperkeeper-jetty9-webserver. (PDB-1439)

Documentation

Deprecations

• We have marked the url-prefix setting as deprecated and will remove it in a future release. (PDB-1485)

• We have marked the event-counts and aggregate-event-counts endpoints as experimental, and may change or remove them in a future release. (PDB-1479)

2.3.3

PuppetDB 2.3.3 is a backwards-compatible bugfix release that adds support for Puppet 4 on Debian and Ubuntu platforms.

Upgrading

• For the best-possible performance and scaling capacity, we recommend PostgreSQL version 9.4 or newer with the pg_trgm extension enabled, as explained here, and we have officially deprecated versions earlier than 9.2. HSQLDB is only recommended for local development because it has a number of scaling and operational issues.

Bug Fixes and Maintenance

• PuppetDB now supports Puppet 4 on Debian and Ubuntu. (PDB-1389)

2.3.2

PuppetDB 2.3.2 is a backwards-compatible bugfix release that corrects two problems which could prevent migration to the database format introduced in 2.3.1. Neither problem presented risk of data loss, and users that upgraded successfully will not be affected by these changes.

Upgrading

• For the best-possible performance and scaling capacity, we recommend PostgreSQL version 9.4 or newer with the pg_trgm extension enabled, as explained here, and we have officially deprecated versions earlier than 9.2. HSQLDB is only recommended for local development because it has a number of scaling and operational issues.

Changes

Bug Fixes and Maintenance

• The database migration required by the garbage collection fix in 2.3.1 should no longer refuse to complete when the existing database contains values with different types, but the same path, in different factsets, i.e. (factset path value):

  1 "pip_version" false
  2 "pip_version" "1.5.6-5"
  

  (PDB-1362)

• PuppetDB won't assume that it can retrieve the public database table names (initially assumed in 2.3.1). (PDB-1363)

2.3.1

PuppetDB 2.3.1 is a backwards-compatible bugfix release that may notably increase performance for larger installations.

Upgrading

• For the best-possible performance and scaling capacity, we recommend PostgreSQL version 9.4 or newer with the pg_trgm extension enabled, as explained here, and we have officially deprecated versions earlier than 9.2. HSQLDB is only recommended for local development because it has a number of scaling and operational issues.

• Make sure that all of your PuppetDB instances are shut down, and only upgrade one at a time.

Changes

• The tk-jetty9-version has been upgraded from 1.2.0 to 1.3.0. (PDB-1307)

Bug Fixes and Maintenance

• We have reworked out table schema and fact value garbage collection to ensure that concurrent updates cannot lead to fact GC failures. Before this fix PuppetDB, under high load, could end up in a situation which would produce PostgreSQL log messages like this:

  ERROR: update or delete on table "fact_paths" violates foreign key constraint "fact_values_path_id_fk" on table "fact_values" DETAIL: Key (id)=(11) is still referenced from table "fact_values". STATEMENT: COMMIT

  The fix for this problem may also significantly increase PuppetDB's performance in some situations. (PDB-1031 PDB-1224 PDB-1225 PDB-1226 PDB-1227)

• Report timestamps should be hashed consistently now. (PDB-1286)

• The facter requirement has been removed from the RPM specfile. (PDB-1303)

Documentation

• The documentation has been updated for Puppet 4. (PDB-1305)

• Omitted .html extensions have been added to some the links in the 2.3.0 release notes.

• The documentation sidebar (TOC) is now hosted in the PuppetDB repository. (PDB-1319)

2.3.0

PuppetDB 2.3.0 is a backwards-compatible release that adds support for Puppet 4.

Upgrading

• For the best-possible performance and scaling capacity, we recommend PostgreSQL version 9.4 or newer with the pg_trgm extension enabled, as explained here, and we have officially deprecated versions earlier than 9.2. HSQLDB is only recommended for local development because it has a number of scaling and operational issues.

• Make sure that all of your PuppetDB instances are shut down, and only upgrade one at a time.

• Make sure to upgrade your puppetdb-terminus package (on the host where your Puppet master lives), and restart your master service.

Changes

New Features

• PuppetDB now supports Puppet 4

• To support Puppet 2.7.x - 3.7.x. PuppetDB now handles hyphenated classnames (PDB-1024 PDB-1277)

Deprecations

• The certificate-whitelist setting has been moved from [jetty] to the [puppetdb] section of the configuration file, and the old location has been deprecated. (PDB-813)

Bug Fixes and Maintenance

• NULL environment_ids should no longer prevent garbage collection. (PDB-1076)

  If a factset, report, or catalog is migrated from an earlier PuppetDB version or is submitted via an earlier puppetdb-terminus version, it will have NULL for the environment_id. Previously that could prevent PuppetDB from cleaning up any environments at all. The fix should also improve collection performance.

• The puppet-env script should no longer contain invalid code. Previously commands could end up on the same line, preventing (for example) environment variables from being set correctly. (PDB-1212)

• PuppetDB now uses the new Puppet Profiler API. (PUP-3512)

• Profiler.profile() should now be called with the correct arguments across all supported versions. (PDB-1029)

• PuppetDB has migrated to a newer version of Trapperkeeper which among other things, should help alleviate some startup failures on systems with larger CPU core counts. (PDB-1247)

• The factset endpoint should no longer accept some unused and unintentionally accepted arguments.

Documentation

• The documentation for the <= and >= operators has been fixed (the descriptions were incorrectly reversed).

• The firewall and SELinux requirements have been documented here. (PDB-137)

• Broken links have been fixed in the connection and commands documentation.

• A missing -L option has been added to a curl invocation here.

• An incorrect reference to "Java" has been changed to "JVM" in the configuration documentation.

• The relationship between "MQ depth" and "Command Queue depth" has been clarified in the tuning and maintenance documentation.

• An example that uses curl with SSL to communicate with Puppet Enterprise has been added to the curl documentation.

• Some minor edits have been made to the fact-contents, connection, and KahaDB Corruption documentation.

Testing

• The tests have been adjusted to accommodate Puppet 4. (PDB-1052 PDB-995 PDB-1271 68bf176e0bd4d51c1ba3 9ef68b635d1bb1f5338b)

• The memory limit has been raised to 4GB for Travis CI tests. (PDB-1202)

• For now, the Fedora acceptance tests pin Puppet to 3.7.3. (PDB-1200)

• The Puppet version used by the spec tests can now be specified. (PDB-1012)

  The desired puppet version can be selected by setting the puppet_branch environment variable. Values of latest and oldest will select the latest and oldest supported versions of puppet respectively.

• The bundler --retry argument is now used during acceptance testing.

• Retriable has been pinned to version ~> 1.4 to avoid Ruby 1.9.x incompatible versions.

• The tree-generator should be less likely to generate inappropriate test data. (PDB-1109)

• The source of the Leiningen command has been updated.

• The ec2 acceptance test template's el-5 image has been updated. (7cd01ac051c719c6c768)

• Some v4 node test failures should no longer be hidden. (PDB-1017)

• Pull request testing now invokes a script from the repository instead of the Jenkins job. (PDB-1034)

• The Gemfile pins i18n to ~> 0.6.11 for Ruby 1.8.7 to prevent activesupport from pulling in a version of i18n that isn't compatible with Ruby 1.8.7.

• The acceptance tests now use Virtual Private Cloud (VPC) hosts.

• The Beaker AWS department (BEAKER_department) is now set to eso-dept for the acceptance tests to improve AWS usage reporting.

• The legacy certificate whitelist test has been fixed. (PDB-1247)

2.2.2

PuppetDB 2.2.2 is a backwards-compatible security release to update our default ssl settings and tests in response to the POODLE SSLv3 vulnerability disclosed 10/14/2014.

(see http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3566)

Before Upgrading

• For best-possible performance and scaling capacity, we recommend using the latest version of PostgreSQL (9.3 or higher). We have officially deprecated PostgreSQL 9.1 and below. If you are using HSQLDB for production, we also recommended switching to PostgreSQL at least 9.3, as HSQLDB has a number of scaling and operational issues and is only recommended for testing and proof of concept installations.

• For PostgreSQL 9.3 we advise that users install the PostgreSQL extension pg_trgm for increased indexing performance for regular expression queries. Using the command create extension pg_trgm as PostgreSQL super-user and before starting PuppetDB will allow these new indexes to be created.

• Ensure during a package upgrade that you analyze any changed configuration files. For Debian you will receive warnings when upgrading interactively about these files, and for RedHat based distributions you will find that the RPM drops .rpmnew files that you should diff and ensure that any new content is merged into your existing configuration.

• Make sure all your PuppetDB instances are shut down and only upgrade one at a time.

• As usual, don't forget to also upgrade your puppetdb-terminus package (on the host where your Puppet master lives), and restart your master service.

• If you receive the error "Could not open /etc/puppet/log4j.properties" or "Problem parsing XML document", this is because we have changed the packaged config.ini to point at a new logging configuration file: logback.xml. However during package installation some package managers will cowardly refuse to just update config.ini, this in particular affects RPM. After upgrading you should ensure any .rpmnew files are reviewed and that changes to our vendored version are now merged with your version of config.ini on disk. See PDB-656 for more details.

• If you are running Ubuntu 12.04 and Ruby 1.9.3-p0 you may find that you will sometimes receive the error "idle timeout expired" in your Puppet agent/master logs and your PuppetDB logs. This is due to a bug in that version of Ruby in particular. See PDB-686 for more details.

2.2.1

PuppetDB 2.2.1 consists of bug fixes and documentation updates and is backwards compatible with PuppetDB 2.2.0.

Before Upgrading

• For best-possible performance and scaling capacity, we recommend using the latest version of PostgreSQL (9.3 or higher). We have officially deprecated PostgreSQL 9.1 and below. If you are using HSQLDB for production, we also recommended switching to PostgreSQL at least 9.3, as HSQLDB has a number of scaling and operational issues and is only recommended for testing and proof of concept installations.

Database and Performance

• PDB-900 Make performance improvements to fact values GC process

  Switched from a background thread to cleanup orphaned fact_values to one that deletes as it goes. Switching to deferred constraints also significantly improved performance on PostgreSQL. Deferred constraints are not available in HSQLDB, but since HSQLDB is unlikely to be running at the scale that will surface the issue, simply switching to delete-as-you-go should be sufficient to mitigate the issue to the extent that HSQL installations are affected.

Bug Fixes and Maintenance

• PDB-847 remove GlobalCheck for PE compatibility

  This patch deletes the GlobalCheck method that ran before each call to the PDB indirectors to check that the running version of Puppet was greater than 3.5. The check is redundant because Puppet 3.5 is a requirement for puppetdb-terminus and was causing a bug by mis-parsing PE semvers.

• PDB-707 The first request to PuppetDB after DB backend restart fails

  This patch adds retry handling for 57P01 failures, which result in an PSQLException with a status code of 08003. The patch has been made forward compatible by catching all SQLExceptions with this status code.

  Version 0.8.0-RELEASE of Bonecp does not throw the correct sql state code today, however a patch has been raised to make this happen so we can upgrade to this version in the future.

• PDB-653 DLO metrics don't update on PDB startup

  Previously, the DLO metrics only updated on a failed command submission, which meant restarting PDB would blank the metrics until the next failure. This patch initializes DLO metrics on PDB startup if the DLO directory, which is created on first failure, already exists.

• PDB-865 PDB 2.2 migration fails when nodes have no facts

  This patch handles an error that occurs if a user attempts the 2.2 upgrade with nodes that have no associated facts in the database, and adds some additional testing around the migration.

• PDB-868 Add exponential backoffs for db retry logic

  This patch increases the number of retries and adds exponential backoff logic to avoid the case where the database is still throwing errors for a short period of time. This commonly occurs during database restarts.

• PDB-905 Fix containment-path for skipped events

  We had removed some < v4 reporting code as part of the last release, but I had also accidentally removed containment-path for skipped events. This was an effort to drop older Puppet support basically.

  This patch fixes that problem, and fixes the tests.

  I've also cleaned up a couple of other typos and style items, plus removed one more case of < v4 report format checking.

• PDB-904 Switch fact_values.value_string trgm index to be GIN not GIST

  There were reports of crashing due to a bug in pg_trgm indexing when a large fact value was loaded into PuppetDB.

  This patch removes the old index via migration, and will then replace it with the index handling mechanism.

• Add thread names to logging

  This patch adds thread names to the various logback.xml configuration files in this project. This provides us with better traceability when attempting to understand where a log message came from.

Documentation

• DOCUMENT-18 Mention DLO cleanup in docs

• PDB-347 Add docs for new CRL and cert-chain TK features

• Updated contributor link to https://cla.puppetlabs.com/

Testing

• PDB-13 Add acceptance test for Debian Wheezy

  This patch adds Debian Wheezy to our acceptance tests.

• Allow beaker rake task to accept preserve-hosts options

  In the past it just allowed true/false, but the current beaker accepts a series of options, including 'onfail'. This change passes through the value specified in the environment variable BEAKER_PRESERVE_HOSTS.

• Remove deprecated open_postgres_port option from puppetdb helper class

2.2.0

This release was primarily focused on providing structured facts support for PuppetDB. Structured facts allow a user to include hashes and arrays in their fact data, but also it provides the availability of proper typing to include the storage of integers, floats, booleans as well as strings.

This release introduces the ability to store structured facts in PuppetDB, and use some new enhanced API's to search and retrieve that data also.

With this change we have introduced the capability to store and retrieve trusted facts, which are stored and retrieved in the same way as structured facts.

Before Upgrading

• It is recommended for greater scaling capabilities and performance, to use the latest version of PostgreSQL (9.3 or higher). We have officially deprecated PostgreSQL 9.1 and below. If you are using HSQLDB for production, it is also recommended that you switch to PostgreSQL at least 9.3, as HSQLDB has a number of scaling and operational issues, and is only recommended for testing and proof of concept installations.

• For PostgreSQL 9.3 you are advised to install the PostgreSQL extension pg_trgm for increased indexing performance for regular expression queries. Using the command create extension pg_trgm as PostgreSQL super-user and before starting PuppetDB will allow these new indexes to be created.

• Ensure during a package upgrade that you analyze any changed configuration files. For Debian you will receive warnings when upgrading interactively about these files, and for RedHat based distributions you will find that the RPM drops .rpmnew files that you should diff and ensure that any new content is merged into your existing configuration.

• Make sure all your PuppetDB instances are shut down and only upgrade one at a time.

• As usual, don't forget to upgrade your puppetdb-terminus package also (on the host where your Puppet master lives), and restart your master service.

• If you receive the error "Could not open /etc/puppet/log4j.properties" or "Problem parsing XML document", this is because we have changed the packaged config.ini to point at a new logging configuration file: logback.xml. However during package installation some package managers will cowardly refuse to just update config.ini, this in particular affects RPM. After upgrading you should ensure any .rpmnew files are reviewed and that changes to our vendored version are now merged with your version of config.ini on disk. See PDB-656 for more details.

• If you are running Ubuntu 12.04 and Ruby 1.9.3-p0 then you may find that you will sometimes receive the error "idle timeout expired" in your Puppet agent/master logs, and your PuppetDB logs. This is due to a bug in that version of Ruby in particular. See PDB-686 for more details.

New Features

New Endpoints

• /v4/fact-contents

  This end-point provides a new view on fact data, with structure in mind. It provides a way to traverse a structured facts paths and their values to search for and retrieve data contained deep within hashes, arrays and combinations there-of.

• /v4/fact-paths

  To aid with client application autocompletion and ahead-of-time fact schema layout this endpoint will provide the client with a full list of potential fact paths and their value types. This data is primarily used by user agents that wish to perhaps confine input via a form, or provide some level of autocompletion advice for a user typing a fact search.

• /v4/factsets

  This endpoint has been created to facilitate retrieval of factsets submitted for a node. With structured facts support, this includes preserving the type of the fact which may include a hash, array, real, integer, boolean or string.

  We have now switched to using this endpoint for the purposes of puppetdb export. This allows us to grab a whole node factsets in one go, in the past we would have to reassemble multiple top level facts to achieve the same results.

Changes to Endpoints

• /v4/facts

  This endpoint is now capable of returning structured facts. Facts that contain hashes, arrays, floats, integers, booleans, strings (and combinations thereof) will be preserved when stored and able to now be returned via this endpoint.

• /v3/facts

  This endpoint will return JSON stringified structured facts to preserve backwards compatibility.

Operators

• in and extract (version 4)

  We have modified the v4 IN and EXTRACT operators to accept multiple fields at once. This allows the following...

    ["and" ["in", "name",
             ["extract", "name", [select-fact-contents ["=","value",10]]]]
           ["in", "certname",
             ["extract", "certname", [select-fact-contents ["=", "value", 10]]]]]
  

  to be re-written as

    ["in", ["name","certname"],
      ["extract", ["name", "certname"], ["select-fact-contents", ["=", "value", 10]]]]
  

  This was made to allow users to combine the fact-contents endpoint with the facts endpoint to combine the power of hierachical searching and aggregate results.

• ~> (version 4)

  This new operator was designed for the path field type to allow for matching a path against an array of regular expressions. The only endpoints that contains such fields today are /v4/fact-contents and /v4/fact-paths.

Commands

In preparation for some future work, we have provided the ability to pass a producer-timestamp field via the replace facts and replace catalogs commands. For replace facts we have also added the ability to pass any JSON object as the keys to the value field.

Due to these two changes, we have cut new versions of these commands for this release:

• replace catalog version 5
• replace facts version 3

The older versions of the commands are immediately deprecated.

Terminus

The terminus changes for structured facts are quite simple, but significant:

• We no longer convert structured data to strings before submission to PuppetDB.
• Trusted facts have now been merged into facts in our terminus under the key trusted.

This means that for structured and trusted fact support all you have to do is enable them in Puppet, and PuppetDB will start storing them immediately.

Database and Performance

• As part of the work for PDB-763 we have added a new facility to nag users to install the pg_trgm extension so we can utilize this index type for regular expression querying. This work is new, and only works on PostgreSQL 9.3 or higher.

• We have added two new garbage collection SQL cleanup queries to remove stale entries for structured facts.

Import/Export/Anonymization

All these tools have been modified to support structured facts. export specifically uses the new /v4/factsets endpoint now.

Deprecations and Retirements

• We have now deprecated PostgreSQL 9.1 and older
• We no longer produce packages for Ubuntu 13.10 (it went EOL on July 17 2014)

Bug Fixes and Maintenance

• PDB-762 Fix broken export

  This pull request fixes a malformed post-assertion in the events-for-report-hash function that caused exports to fail on unchanged reports. Inserting proper parentheses made it apparent that a seq, rather than a vector, should be the expected return type.

• PDB-826 Fix pathing for puppetdb-legacy

  For PE the puppetdb-legacy scripts (such as puppetdb-ssl-setup) expect the puppetdb script to be in the path. This assumption isn't always true, as we install PE in a weird place.

  This patch adjusts the PATH for this single exec so that it also includes the path of the directory where the original script is found, which is usually /opt/puppet/sbin.(PDB-826) Fix pathing for puppetdb-legacy

• PDB-764 Malformed post conditions in query.clj.

  This fixes some trivial typos in query.clj that had previously caused some post-conditions to go unenforced.

Documentation

• DOCUMENT-97 Mention updating puppetdb module

  Upgrading PuppetDB using the module is pretty easy, but we should point out that the module should be updated first.

• PDB-550 Update PuppetDB docs to include info on LibPQFactory

  We have now updated our PostgreSQL SSL connectivity to documentation to include details on how to use the LibPQFactory methodology. This hopefully will alleviate the need to modify your global JVM JKS when using Puppet and self-signed certificates.

• Fix example for nodes endpoint to show 'certname' in response

• Revise API docs for updated info, clarity, consistency, and formatting

  This revision touches most of the pages in the v3 and v4 API docs, as well as the release notes. We've:

  • Standardized some squirmy terminology
  • Adjusted the flow of several pages
  • Caught two or three spots where the docs lagged behind the implementation
  • Made the Markdown syntax a little more portable (summary: Let's not use the "\n: " definition list syntax anymore. Multi-graf list items and nested lists get indented four spaces, not two or three.)
  • Added context about how certain objects work and how they relate to other objects
  • Added info about how query operators interact with field data types

• Change some old URLs, remove mentions of inventory service.

  Some of these files have moved, and others should point to the latest version instead of a specific version.

  And the inventory service is not really good news anymore. People should just use puppetdb's api directly.

Testing

• PDB-822 Change acceptance tests to incorporate structured facts.

  This patch augments our basic_fact_retrieval and import_export acceptance tests to include structured facts, and also bumps the version of the nodes query in the facts/find indirector so structured facts are returned when puppet facts find is issued to the PDB terminus.

• Split out acceptance and unit test gems in a better way

  We want to avoid installing all of the unit test gems when running acceptance. This patch moves rake into its own place so we can use --without test with bundler properly.

• Switch confine for basic test during acc dependency installation

  The way we were using confine was wrong, and since this is now more strict in beaker it was throwing errors in the master smoke tests. This patch just replaces it for a basic include? on the master platform instead.

• Fix old acceptance test refspec issue

  The old refspec for acceptance testing source code only really worked for the PR testing workflow. This patch makes it work for the command line or polling based workflow as well.

  Without it, it makes it hard to run beaker acceptance tests from the command line.

2.1.0

PuppetDB 2.1.0 is a feature release focusing on new query capabilities, streaming JSON support on all endpoints and a new report status field for determining if a Puppet run has failed. Note that this release is backward compatible with 2.0.0, but users must upgrade PuppetDB terminus to 2.1.0 when upgrading the PuppetDB instance to 2.1.0.

Things to take note of before upgrading:

• If you receive the error "Could not open /etc/puppet/log4j.properties" or "Problem parsing XML document", this is because we have changed the packaged config.ini to point at a new logging configuration file: logback.xml. However during package installation some package managers will cowardly refuse to just update config.ini, this in particular affects RPM. After upgrading you should ensure any .rpmnew files are reviewed and that changes to our vendored version are now merged with your version of config.ini on disk. See PDB-656 for more details.

• If you are running Ubuntu 12.04 and Ruby 1.9.3-p0 then you may find that you will sometimes receive the error "idle timeout expired" in your Puppet agent/master logs, and your PuppetDB logs. This is due to a bug in that version of Ruby in particular. See PDB-686 for more details.

• Make sure all your PuppetDB instances are shut down and only upgrade one at a time.

• As usual, don't forget to upgrade your puppetdb-terminus package also (on the host where your Puppet master lives), and restart your master service.

New Features:

• (PDB-660) Switch all query endpoints to stream JSON results

  The following endpoints have been switched over to streaming:

  • event-counts
  • reports
  • nodes
  • environments
  • events

  Using 'event-query-limit' is now deprecated, use the normal paging/streaming functionality to achieve the same results.

• (PDB-658, PDB-697) Implement new "query engine" for v4

  This rewrite of the v4 API query infrastructure unifies query operators across all endpoints. Each endpoint now supports all operators appropriate for the given field of that type. As an example, any string field can now be searched by regular expression. All dates can be search with inequality operators like < or > for searching via date ranges. There are also many new queryable fields. Below summarizes the new features of the switch to this query engine

  events endpoint

  • Added configuration-version as a queryable field
  • Added containment-path as a queryable field (queryable in a way similar to tags)

  nodes endpoint

  • Added facts-timestamp, catalog-timestamp, report-timestamp as a queryable field

  reports endpoint

  • Added puppet-version, report-format, configuration-version, start-time, end-time, receive-time, transaction-uuid as queryable fields

  null? operator

  • new operator that checks for the presence or absence of a value

  Some endpoints previously returned NULL values when using a "not" query such as ["not", ["=", "line", 10]]. The query engine follows SQL semantics, so if you want NULL values, you should explicty ask for it like:

  ["or", ["not", ["=", "line", 10]] ["null?", "line" true]]

• (PDB-162) Add regexp support to resource parameter queries

  The query engine supported this, but the existing "rewrite" rule, to go from the shorthand parameter syntax to the nested resource query didn't recognize ~. That is fixed with this commit, so regexps will now work on parameters.

• (PDB-601) Do not require query operator on reports endpoint

  With this pull request, hitting the reports endpoint without a query argument will return the full reports collection. This behavior is consistent with that of the nodes, facts, and resources endpoints.

• (PDB-651) Allow the web app URL prefix to be configurable

  Previously PuppetDB always used the context root "/", meaning all queries etc would be something like "http://localhost:8080/v4/version". This change allows users to specify a different context root, like "http://localhost:8080/my-context-root/v4/version". See the url-prefix configuration documentation for more info

• (PDB-16) Add status to stored reports

  Previously there was no way to distinguish between failed puppet runs and successful puppet runs as we didn't store report status. This commit adds support for report status to the "store report" command, v4 query API and model.

• (PDB-700) Allow changes to maxFrameSize in activemq

  maxFrameSize previously defaulted to 100 MB. Now default is 200 MB with user configurability.

Bug Fixes and Maintenance:

• (PDB-675) Fix Debian/Ubuntu PID missing issue

  In the past in Debian and Ubuntu releases we had issues where the PuppetDB system V init scripts were not stopping the PuppetDB process whenever a PID file was missing. This patch now introduces a fallback that will kill any java process running as the puppetdb user, if the PID file is missing.

• (PDB-551) Created a versioning policy document

  This document let's consumers of the PuppetDB API know what to expect from an API perspective when new versions of PuppetDB are release. This document is a separate page called "Versioning Policy" and is included in our API docs

• (PDB-164) Add documentation for select-nodes subquery operator

  This pull request supplies V4 API documentation for the select-nodes subquery operator, which was previously supported but undocumented.

• (PDB-720) Fix services test with hard coded Jetty port

  Fixed this issue by moving code that dynamically picks a free port out of import-export-roundtrip and into a separate ns. I just switched the services test to use that code and there should no longer be conflicts.

• (RE-1497) Remove quantal from build_defaults

  This commit removes quantal from all build defaults because it is end of life. It removes the defaults from the build_defaults yaml.

• (PDB-240) Replace anonymize.clj read-string with clojure.edn/read-string

  This patch replaces a call to read-string in anonymize.clj with a call to clojure.edn/read-string. Unlike clojure.core/read-string, clojure.edn/read-string is safe to use with untrusted data and guaranteed to be free of side-effects.

• (PDB-220) Coerce numerical function output in manifests to string

  Previously, when a user defined a numeric-valued function in a puppet manifest and submitted it to notify, the resource-title would remain numeric and PuppetDB would throw exceptions while storing reports. Per the docs, resource-title must be a string. This pull request avoids the problem by coercing resource-title to string.

• (PDB-337) Remove extraneous _timestamp fact

  Previously a _timestamp fact was submitted to puppetDB even though timestamp was originally intended for internal use. This commit strips internal data (all preceded by "") from the factset before submission to PuppetDB.

• (PDB-130) Fixes a nasty traceback exposed when users run import from command line with an invalid filename. A friendly message is now printed instead.

• (PDB-577) Lower KahaDB MessageDatabase logging threshold.

  Previously, premature termination of PuppetDB import under specific ownership conditions led to a residual KahaDB lock file that could prevent subsequent imports from running with no obvious reason why. This patch lowers the log threshold for KahaDB MessageDataBase so affected users are informed.

• (PDB-686) Add warning about PDB-686 to release notes

  This adds a warning about PDB-686 to the release notes so users know how to work-around it.

  This also cleans up the linking in our current release notes, and removes the warning about Puppet 3.4.x, because we pin against 3.5.1 and greater anyway.

• Add sbin_dir logic to Rakefile for Arch linux

• (PDB-467) Merge versioning tests for http testing into non-versioned files

  This patch removes all remaining versioned http test files into shared unversioned files, so that we may start iterating across versions in the same file.

• Fix comparison in dup resources acceptance test

  Due to changes in Puppet 3.6.0, the comparison done in our resource duplication tests no longer matches the actual output. This patch ammends the comparison to match Puppet 3.6.0 output now.

• (PDB-597) Add trusty build default

  This includes trusty (Ubuntu 14.04) in our builds.

• Unpin the version of beaker

  We had pinned beaker previously because we were waiting for some of our new EC2 customisations to be merged in and released. This has been done now.

• Fix a race condition in the import/export round-trip clojure tests

  This scenario occurred if command processing for facts is slow. A result with the hard coded certname would be returned with no fact values or environment. This commit fixes the code to only return results when facts are found.

• (PDB-309) Update config conversion code for Schema 0.2.1

  Much of the code for converting user provided config to the internal types (i.e. "10" to Joda time 10 Seconds etc) is no longer necessary with the new coerce features of Schema. This commit switches to the new version and makes the necessary changes to use the coerce feature.

2.0.0

PuppetDB 2.0.0 is a feature release focusing on environments support. Note that this is a major version bump and there are several breaking changes, including dropping support for versions of PostgreSQL prior to version 8.4 and Java 1.6. See the "Deprecations and potentially breaking changes" section below for more information.

Things to take note of before upgrading:

• If you receive the error "Could not open /etc/puppet/log4j.properties" or "Problem parsing XML document", this is because we have changed the packaged config.ini to point at a new logging configuration file: logback.xml. However during package installation some package managers will cowardly refuse to just update config.ini, this in particular affects RPM. After upgrading you should ensure any .rpmnew files are reviewed and that changes to our vendored version are now merged with your version of config.ini on disk. See PDB-656 for more details.

• If you are running Ubuntu 12.04 and Ruby 1.9.3-p0 then you may find that you will sometimes receive the error "idle timeout expired" in your Puppet agent/master logs, and your PuppetDB logs. This is due to a bug in that version of Ruby in particular. See PDB-686 for more details.

• Make sure all your PuppetDB instances are shut down and only upgrade one at a time.

• As usual, don’t forget to upgrade your puppetdb-terminus package also (on the host where your Puppet master lives), and restart your master service.

New features:

• (PDB-452,453,454,456,457,526,557) Adding support for storing, querying and importing/exporting environments

  This change forced a new revision of the replace facts, replace catalog and store report commands. The PuppetDB terminus also needed to be updated to support new environment information being sent to PuppetDB. USERS MUST ALSO UPDATE THE PUPPETDB TERMINUS. Previous versions of those commands (and wire formats) are now deprecated. See the PuppetDB API docs for more information. Environments support has been added to the new v4 (currently experimental) query API. The following query endpoints now include environment in the response:

  • facts
  • resources
  • nodes
  • catalogs
  • reports
  • events
  • event counts
  • aggregate event counts

  The below query endpoints now allow query/filtering by environment:

  • facts
  • resources
  • nodes
  • catalogs
  • reports
  • events

  This release also includes a new environments query endpoint to list all known environments and allow an easy filtering based on environment for things like events, facts reports and resources. See the query API docs for more information. PuppetDB import/export/anonymization and benchmark tool also now have environment support. Storeconfigs export does not include environments as that information is not being stored in the old storeconfigs module. Environments that are no longer associated with a fact set, report or catalog will be "garbage collected" by being removed from the database.

• (PDB-581) Add subqueries to events query endpoint

  The events endpoint now supports select-resources and select-facts

• (PDB-234) Add v4 query API, deprecate v2 query API

  This patch adds the new code relevant for doing any future v4 work. It has been raised as an experimental end-point only so there are no commitments to its interface yet. Once stable we will need another patch to declare it as so.

  This patch also deprecates the v2 end-point in documentation and by adding the same headers we used to use for the v1 end-point.

• (PDB-470) Provide new db setting 'statements-cache-size' with a default of 1000

  This setting adjusts how many SQL prepared statements get cached via BoneCP.

  By using this setting we've seen an almost 40% decrease in wall clock time it takes to store a new catalog.

  This patch adds the new configuration item as a user configurable one, with a default set to 1000 for now. Documentation has also been added for this setting.

• (PDB-221) Add facts to import/export

  This commit imports/exports facts similar to how we currently import/export catalogs and reports. Anonymize doesn't currently work for facts, which is going to be added separately.

• (PDB-469) - Support Anonymizing Facts

  This commit adds support for the anonymization of facts. The levels of anonymization supported are:

  • none - no anonymization
  • low - only values with a fact name of secret, password etc
  • moderate - recognized "safe" facts are untouched, recognized facts with sensitive information (i.e. ipaddress) have their values anonymized
  • full - all fact names and values are anonymized

Deprecations and potentially breaking changes:

• (PDB-88, PDB-271) JDK 1.6 no longer supported

• (PDB-308) Drop 2.7.x support

  This patch removes support for Puppet 2.7.x in several ways:

  • New check for every entry point in terminus will return an error if the version of Puppet is not supported. This is done in a 'soft' manner to avoid Puppet from not working.
  • Documentation now only references Puppet 3
  • Documentation now states only latest version of Puppet is supported
  • Packaging now has hard dependencies on the latest version of Puppet
  • Contrib gemspec has been updated
  • Gemfile for tests have been updated

• (PDB-552) Pin support for Puppet to 3.5.1 and above

  Starting PuppetDB with a Puppet earlier than 3.5.1 will now fail on startup.

• (PDB-605) Pin facter requirement to 1.7.0

  Using prior versions of Facter will cause PuppetDB to fail on startup

• (PDB-592) Removing support for Ubuntu Raring

  Raring went EOL in Jan 2014, so we are no longer building packages for it.

• (PDB-79) Drop support for Postgres < 8.4

  PuppetDB will now log an error and exit if it connects to an instance of Postgres older than 8.4. Users of older versions will need to upgrade (especially EL 5 users as it defaults to 8.1). The acceptance tests for EL 5 have been updated to be explicit about using Postgres 8.4 packages instead.

• (PDB-204) Ensure all commands no longer need a serialized payload

  Some previous commands required the payload of the command to be JSON serialized strings as opposed to the relevant JSON type directly in the payload. All commands no longer require the payload to be serialized to a string first.

• (PDB-238) - Remove v1 API

  This commit removes the v1 API and builds on the HTTP api refactor. This commit contains:

  • Remove all v1 namespaces and the namespaces calling them
  • Remove api tests excercising the v1 routes
  • Remove v1 references in the docs

• (PDB-354) Deprecate old versions of commands

  This patch drops a warning whenever an old version of the commands API is used and updates the documentation to warn the user these old commands are deprecated.

• (PDB-570) Remove planetarium endpoint

  Old endpoint that had significant overlap with the current catalogs endpoint

• (PDB-113) Remove swank

  As swank is now a deprecated project. This patch removes swank support completely from the code base.

Notable improvements and fixes:

• (PDB-473) Support POST using application/json data in the body

  This patch adds to the commands end-point the ability to simply POST using application/json with the JSON content in the body.

  It also switches the terminus to use this mechanism.

  We found that the url encode/decode required to support x-www-form-urlencoded was actually quite an overhead in a number of ways:

  • The urlencode on the terminus added overhead
  • The urldecode in the server added overhead
  • The interim strings created during this encode/decode process can get quite large increasing the amount of garbage collection required

  This feature has been implemented by providing a new middleware that will move the body into the parameter :body-string of the request when the content-type is not set to application/x-www-form-urlencoded. This provides a convenient backwards compatible layer so that the old form url encoding can still be supported for older versions of the API.

• (PDB-567,191) Use hash not config_version for report export files

  This fixes a bug related to config_versions containing characts not safe to be use in file names (such as '/').

• (PDB-518) Fix bug storeconfig export of arrays

  For exported Resources with parameters which value is a Array the storeconfig export fails to collect them. Instead of collecting all the parameter values into a array it simply override the value with each value in turn.

• (PDB-228) Use JSON in terminus instead of PSON

  The PuppetDB API specifies that it is JSON, so we should parse it as that and not as PSON.

  Some Puppet classes (Puppet::Node and Puppet::Node::Facts) don't support JSON serialization, so continue to use PSON serialization for them. In Puppet 3.4.0+ they have methods to do seralization in other formats than PSON though, so once support for older versions of Puppet is dropped they can be seralized in JSON as well.

• (PDB-476) Decorate the terminus code with Puppet profiling blocks

  This patch adds some select profiling blocks to the PuppetDB terminus code.

  The profiler is provided by puppet core from Puppet::Util::Puppetdb#profile, which has recently become public for our use. We provide here in our own utils library our own wrapper implementation that can be mixed in.

  Key areas of our terminus functionality have now been profiled with this patch:

  • Entry points are profiled and identified by their entry methods (save, find, search etc.)
  • Remote calls, HTTP gets/posts
  • Code that does any form of encoding/decoding that might be potentially slow at capacity.

  The style of messages I've used follow along with the existing Puppet profiling examples already in place so as to be readable together. We have prefixed our profile message with "PuppetDB" for easy searchability also.

  I have provided a small FAQ entry that explains in brief the process of debugging, although we lack something to link to in Puppet for a more detailed explanation. This will probably need to be fixed if better documentation comes available.

• (PDB-472) - Annotate MQ messages without parsing payload

  Received time and a UUID are currently added to incoming (via HTTP) messages before placing them on the queue. This commit adds those annotations to the MQ message header no longer requires parsing the incoming message payload before placing it on the queue.

• (PDB-87) Port PuppetDB to TrapperKeeper

  TrapperKeeper is a new container that PuppetDB will be deployed in. This is mainly a refactoring of existing code and error handling to use the centralized TrapperKeeper service. More information on TrapperKeeper can be found here: http://puppetlabs.com/blog/new-era-application-services-puppet-labs.

• (PDB-401) Upgrade to TrapperKeeper 0.3.4

  This commit updates PuppetDB to use the new trapperkeeper 0.3.4 API. This includes:

  • Slightly modified syntax for defining services and service lifecycle behavior
  • Switch from log4j to logback, update documentation and packaging accordingly
  • Switch from jetty7 to jetty9
  • Add example of how to use "reloaded" interactive development pattern in REPL
  • Upgrade to kitchensink 0.5.3, with bouncycastle fix for improved HTTPS performance

• (PDB-529) Added latest-report? example to the events docs

• (PDB-512) Upgrade to Clojure 1.6.0

• (PDB-521) Switch to using /dev/urandom (using java.security.egd)

• (PDB-564) Added OpenBSD-specific variables to puppetdb.env

  Adding OpenBSD specific variables allows the OpenBSD package maintained downstream in the OpenBSD ports tree to be greatly simplified.

• (PDB-177) Replace ssl-host default with 0.0.0.0

  By trying to use a hostname, the amount of issues people suffer with during setup times related to hostname resolution is quite high. This patch replaces the hostname with 0.0.0.0 which by default listens on all interfaces.

• (PDB-402) Remove ahead-of-time compilation

  This patch removes AOT compilation from our leiningen project and updates all relevant shell scripts to use the non-AOT methodology for invoking clojure projects.

• (PDB-576) Update beaker tests to use host.hostname instead of host.name

• (PDB-481) Added Arch Linux build/install support

• (PDB-572) New community packages of puppet install in vendorlibdir

• (PDB-575) Updated install from source docs

• (PDB-254) Change benchmark to mutate catalog resources and edges send a defined number of messages

  Previously benchmark.clj when it would mutate a catalog would only add a single resource. This change will add a new resource or mutate a random existing resource. It will also add a new or change an existing edge. One of these four mutations is picked at random. This commit also adds a new parameter to benchmark.clj to allow the syncronous sending of a specified number of commands (per host) via the -N argument

• (PDB-591) Allow gem source to come from env vars

• (PDB-595) Added docs for the load testing and benchmarking tool

  Mostly a developer tool, but documented how to use it in case it's useful to others. See "Load Testing" in the Usage / Admin section of the docs site

• (PDB-602) Updated acceptance tests to use a proper release of leiningen

• (DOCUMENT-6) Update config page for PuppetDB module's improved settings behavior

1.6.3

PuppetDB 1.6.3 is a bugfix release.

Notable improvements and fixes:

• (PDB-510) Add migration to fix sequence for catalog.id

  The sequence for catalog.id had not been incremented during insert for migration 20 'differential-catalog-resources'.

  This meant that the catalog.id column would throw a constraint exception during insertion until the sequence had increased enough to be greater then the max id already used in the column.

  While this was only a temporary error, it does cause puppetdb to start to throw errors and potentially dropping some catalog updates until a certain number of catalogs had been attempted. In some cases catalogs had been queued up and retried successfully, other cases meant they were simply dropped into the DLQ.

  The fix is to reset the sequence to match the max id on the catalogs.id column.

• RHEL 7 beta packages are now included

• (PDB-343) Fedora 18 packages are no longer to be built

• (PDB-468) Update CLI tools to use correct JAVA_BIN and JAVA_ARGS

  Some tools such as puppetdb import|export and puppetdb foreground where not honouring the JAVA_BIN defined in /etc/default|sysconfig/puppetdb.

• (PDB-437) Reduce API source code and version inconsistencies

  The API code when split between different versions created an opportunity for inconsistencies to grow. For example, some versioning inside the code supported this file based way of abstracting versions, but other functions required version specific handling.

  This patch solidifies the version handling to ensure we reduce in regressions relating to different versions of the query API and different operator handling.

• Use v3 end-point for import and benchmark tools

• (PDB-80)(packaging) Fixup logic in defaults file for java on EL

• (PDB-463) Fix assertion error in /v1/resources

• (PDB-238) Some code reduction work related to simplifying future query API version removal

• (PDB-446) Start in on the merge of v2 and v3 test namespaces for testing

• (PDB-435) Travis no longer has bundler installed by default, now installing it explicitly

• (PDB-437) Clojure lint cleanups

• Change tutorial and curl documentation examples to use v3 API

• Added examples to documentation for latest-report? and file

1.6.2

PuppetDB 1.6.2 is a bugfix release.

Notable improvements and fixes:

• Provided an early release RPM SPEC for RHEL 7, no automated builds yet.

• (PDB-377) - Fixed a Fedora RPM packaging issue preventing PuppetDB from starting by disabling JAR repacking

• (PDB-341) - Fixed a naming issue when using subqueries for resource metadata like file and line with v3 of the API

• (PDB-128) - Oracle Java 7 package support

  Add support for Oracle Java 7 packages on Debian. This means that users who have older Debian based distros but do not have native JDK 7 packages can build their own Oracle Java 7 package (see https://wiki.debian.org/JavaPackage) and we will pull it in as a dependency.

• (PDB-106) - Added an explicit log message upon a failed agent run (previously would fail with “undefined method `[]' for nil:NilClass”)

• Change the order that filters are applied for events

  When using the distinct-resources flag of an event query, the previous behavior was that we would do the filtering of the events before we would eliminate duplicate resources. This was not the expected behavior in many cases in the UI; for example, when filtering events based on event status, the desired behavior was to find all of the most recent events for each resource first, and then apply the filter to that set of resources. If we did the status filtering first, then we might end up in a state where we found the most recent 'failed' event and showed it in the UI even if there were 'success' events on that resource afterwards.

  This commit changes the order that the filtering happens in. We now do the distinct portion of the query before we do the filtering.

  However, in order to achieve reasonable performance, we need to at least include timestamp filtering in the distinct query; otherwise that portion of the query has to work against the entire table, and becomes prohibitively expensive.

  Since the existing timestamp filtering can be nested arbitrarily inside of the query (inside of boolean logic, etc.), it was not going to be possible to re-use that to handle the timestamp filtering for the distinct part of the query; thus, we had to introduce two new query parameters to go along with distinct-resources: distinct-start-time and distinct-end-time. These are now required when using distinct-resources.

• (PDB-407) - Add Fedora 20 acceptance tests

• (PDB-425) - System V to SystemD upgrade

  Fixed issues upgrading from 1.5.2 to 1.6.2 on Fedora. 1.5.2 used System V scripts while 1.6.x used SystemD which caused failures.

1.6.1

Not released due to SystemD-related packaging issues on Fedora

1.6.0

PuppetDB 1.6.0 is a performance and bugfix release.

Notable improvements and fixes:

• (PDB-81) Deprecate JDK6. It's been EOL for quite some time.

• (#21083) Differential fact storage

  Previously when facts for a node were replaced, all previous facts for that node were deleted and all new facts were inserted. Now existing facts are updated, old facts (no longer present) are deleted and new facts are inserted. This results in much less I/O, both because we have to write much less data and also because we reduce churn in the database tables, allowing them to stay compact and fast.

• (PDB-68) Differential edge storage

  Previously when a catalog wasn't detected as a duplicate, we'd have to reinsert all edges into the database using the new catalog's hash. This meant that even if 99% of the edges were the same, we'd still insert 100% of them anew and wait for our periodic GC to clean up the old rows. We now only modify the edges that have actually changed, and leave unchanged edges alone. This results in much less I/O as we touch substantially fewer rows.

• (PDB-69) Differential resource storage

  Previously when a catalog wasn't detected as a duplicate, we'd have to reinsert all resource metadata into the catalog_resources table using the catalog's new hash. Even if only 1 resource changed out of a possible 1000, we'd still insert 1000 new rows. We now only modify resources that have actually changed. This results in much less I/O in the common case.

• Streaming resource and fact queries. Previously, we'd load all rows from a resource or fact query into RAM, then do a bunch of sorting and aggregation to transform them into a format that clients expect. That has obvious problems involving RAM usage for large result sets. Furthermore, this does all the work for querying up-front...if a client disconnects, the query continues to tax the database until it completes. And lastly, we'd have to wait until all the query results have been paged into RAM before we could send anything to the client. New streaming support massively reduces RAM usage and time-to-first-result. Note that currently only resource and fact queries employ streaming, as they're the most frequently-used endpoints.

• Improvements to our deduplication algorithm. We've improved our deduplication algorithms to better detect when we've already stored the necessary data. Early reports from the field has show users who previously had deduplication rates in the 0-10% range jumping up to the 60-70% range. This has a massive impact on performance, as the fastest way to persist data is to already have it persisted!

• Eliminate joins for parameter retrieval. Much of the slowness of resource queries comes from the format of the resultset. We get back one row per parameter, and we need to collapse multiple rows into single resource objects that we can emit to the client. It's much faster and tidier to just have a separate table that contains a json-ified version of all a resource's parameters. That way, there's no need to collapse multiple rows at all, or do any kind of ORDER BY to ensure that the rows are properly sequenced. In testing, this appears to speed up queries between 2x-3x...the improvement is much better the larger the resultset.

• (#22350) Support for dedicated, read-only databases. Postgres supports Hot Standby (http://wiki.postgresql.org/wiki/Hot_Standby) which uses one database for writes and another database for reads. PuppetDB can now point read-only queries at the hot standby, resulting in improved IO throughput for writes.

• (#22960) Don't automatically sort fact query results

  Previously, we'd sort fact query results by default, regardless of whether or not the user has requested sorting. That incurs a performance penalty, as the DB has to now to a costly sort operation. This patch removes the sort, and if users want sorted results they can use the new sorting parameters to ask for that explicitly.

• (#22947) Remove resource tags GIN index on Postgres. These indexes can get large and they aren't used. This should free up some precious disk space.

• (22977) Add a debugging option to help diagnose catalogs for a host that hash to different values

  Added a new global config parameter to allow debugging of catalogs that hash to a different value. This makes it easier for users to determine why their catalog duplication rates are low. More details are in the included "Troubleshooting Low Catalog Duplication" guide.

• (PDB-56) Gzip HTTP responses

  This patchset enables Jetty's gzip filter, which will automatically compress output with compressible mime-types (text, JSON, etc). This should reduce bandwidth requirements for clients who can handle compressed responses.

• (PDB-70) Add index on catalog_resources.exported

  This increases performance for exported resource collection queries. For postgresql the index is only a partial on exported = true, since indexing on the very common 'false' case is not that effective. This gives us a big perf boost with minimal disk usage.

• (PDB-85) Various fixes for report export and anonymization

• (PDB-119) Pin to RSA ciphers for all jdk's to work-around Centos 6 EC failures

  We were seeing EC cipher failures for Centos 6 boxes, so we now pin the ciphers to RSA only for all JDK's to work-around the problem. The cipher suite is still customizable, so users can override this is they wish.

• Fixes to allow use of public/private key files generated by a wider variety of tools, such as FreeIPA.

• (#17555) Use systemd on recent Fedora and RHEL systems.

• Documentation for store-usage and temp-usage MQ configuration options.

• Travis-CI now automatically tests all pull requests against both PostgreSQL and HSQLDB. We also run our full acceptance test suite on incoming pull requests.

• (PDB-102) Implement Prismatic Schema for configuration validation

  In the past our configuration validation was fairly ad-hoc and imperative. By implementing an internal schema mechanism (using Prismatic Schema) this should provice a better and more declarative mechanism to validate users configuration rather then letting mis-configurations "fall through" to internal code throwing undecipherable Java exceptions.

  This implementation also handles configuration variable coercion and defaulting also, thus allowing us to remove a lot of the bespoke code we had before that performed this activity.

• (PDB-279) Sanitize report imports

  Previously we had a bug PDB-85 that caused our exports on 1.5.x to fail. This has been fixed, but alas people are trying to import those broken dumps into 1.6.x and finding it doesn't work.

  This patch sanitizes our imports by only using select keys from the reports model and dropping everything else.

• (PDB-107) Support chained CA certificates

  This patch makes puppetdb load all of the certificates in the CA .pem file into the in-memory truststore. This allows users to use a certificate chain (typically represented as a sequence of certs in a single file) for trust.

1.5.2

PuppetDB 1.5.2 is a maintenance and bugfix release.

Notable changes and fixes:

• Improve handling of logfile names in our packaging, so that it's easier to integrate with tools like logrotate.

• Better error logging when invoking subcommands.

• Fix bugs in order-by support for facts, fact-names, and resources query endpoints.

• Documentation improvements.

• Add packaging support for Ubuntu saucy.

• Add support for PEM private keys that are not generated by Puppet, and are not represented as key pairs.

• Fix inconsistencies in names of :sourcefile / :sourceline parameters when using nodes/<node>/resources version of nodes endpoint; these were always being returned in the v2 response format, even when using /v3/nodes.

1.5.1

NOTE: This version was not officially released, as additional fixes came in between the time we tagged this and the time we were going to publish release artifacts.

1.5.0

PuppetDB 1.5.0 is a new feature release. (For detailed information about any of the API changes, please see the official documentation for PuppetDB 1.5.)

Notable features and improvements:

• (#21520) Configuration for soft failure when PuppetDB is unavailable

  This feature adds a new option 'soft_write_failure' to the puppetdb configuration. If enabled the terminus behavior is changed so that if a command or write fails, instead of throwing an exception and causing the agent to stop it will simply log an error to the puppet master log.

• New v3 query API

  New /v3 URLs are available for all query endpoints. The reports and events endpoints, which were previously considered experimental, have been moved into /v3. Most of the other endpoints are 100% backwards-compatible with /v2, but now offer additional functionality. There are few minor backwards-incompatible changes, detailed in the comments about individual endpoints below.

• Query paging

  This feature adds a set of new HTTP query parameters that can be used with most of the query endpoints (fact_names, facts, resources, nodes, events, reports, event-counts) to allow paging through large result sets over multiple queries. The available HTTP query parameters are:

  • limit: an integer specifying the maximum number of results to return.
  • order-by: a list of fields to sort by, in ascending or descending order. The legal set of fields varies by endpoint; see the documentation for individual endpoints for more info.
  • offset: an integer specifying the first result in the result set that should be returned. This can be used in combination with limit and order-by to page through a result set over multiple queries.
  • include-total: a boolean flag which, if set, will cause the HTTP response to contain an X-Records header indicating the total number of results that are available that match the query. (Mainly useful in combination with limit.)

• New features available on events endpoint

  • The events data now contains file and line fields. These indicate the location in the manifests where the resource was declared. They can be used as input to an events query.
  • Add new configuration-version field, which contains the value that Puppet supplied during the agent run.
  • New containing-class field: if the resource is declared inside of a Puppet class, this field will contain the name of that class.
  • New containment-path field: this field is an array showing the full path to the resource from the root of the catalog (contains an ordered list of names of the classes/types that the resource is contained within).
  • New queryable timestamp fields: * run-start-time: the time (on the agent node) that the run began * run-end-time: the time (on the agent node) that the run completed * report-receive-time: the time (on the puppetdb node) that the report was received by PuppetDB
  • Restrict results to only include events that occurred in the latest report for a given node: ["=", "latest-report?", true]

• New event-counts endpoint

  v3 of the query API contains a new event-counts endpoint, which can be used to retrieve count data for an event query. The basic input to the endpoint is an event query, just as you'd provide to the events endpoint, but rather than returning the actual events, this endpoint returns counts of successes, failures, skips, and noops for the events that match the query. The counts may be aggregated on a per-resource, per-class, or per-node basis.

• New aggregate-event-counts endpoint

  This endpoint is similar to the event-counts endpoint, but rather than aggregating the counts on a per-node, per-resource, or per-class basis, it returns aggregate counts across your entire population.

• New server-time endpoint

  This endpoint simply returns a timestamp indicating the current time on the PuppetDB server. This can be used as input to time-based queries against timestamp fields that are populated by PuppetDB.

• Minor changes to resources endpoint for v3

  The sourcefile and sourceline fields have been renamed to file and line, for consistency with other parts of the API.

• Minor changes relating to reports storage and query

  • store report command has been bumped up to version 2.
  • Report data now includes a new transaction-uuid field; this is generated by Puppet (as of Puppet 3.3) and can be used to definitively correlate a report with the catalog that was used for the run. This field is queryable on the reports endpoint.
  • Reports now support querying by the field hash; this allows you to retrieve data about a given report based on the report hash for an event returned by the events endpoint.

• Minor changes relating to catalog storage

  • store catalog command has been bumped to version 3.
  • Catalog data now includes the new transaction-uuid field; see notes above.

Bug fixes:

• PuppetDB report processor was truncating microseconds from report timestamps; all timestamp fields should now retain full precision.

• Record resource failures even if Puppet doesn't generate an event for them in the report: in rare cases, Puppet will generate a report that indicates a failure on a resource but doesn't actually provide a failure event. Prior to PuppetDB 1.5, the PuppetDB report processor was only checking for the existence of events, so these resources would not show up in the PuppetDB report. This is really a bug in Puppet (which should be fixed as of Puppet 3.3), but the PuppetDB report processor is now smart enough to detect this case and synthesize a failure event for the resource, so that the failure is at least visible in the PuppetDB report data.

• Filter out the well-known "Skipped Schedule" events: in versions of Puppet prior to 3.3, every single agent report would include six events whose status was skipped and whose resource type was Schedule. (The titles were never, puppet, hourly, daily, weekly, and monthly.) These events were not generally useful and caused a great deal of pollution in the PuppetDB database. They are no longer generated as of Puppet 3.3, but for compatibility with older versions of Puppet, the report terminus in PuppetDB 1.5 will filter these events out before storing the report in PuppetDB.

• Log a message when a request is blocked due to the certificate whitelist: prior to 1.5, when a query or command was rejected due to PuppetDB's certificate whitelist configuration, there was no logging on the server that could be used to troubleshoot the cause of the rejection. We now log a message, in hopes of making it easier for administrators to track down the cause of connectivity issues in this scenario.

• (#22122) Better log messages when puppetdb-ssl-setup is run before Puppet certificates are available.

• (#22159) Fix a bug relating to anonymizing catalog edges in exported PuppetDB data.

• (#22168) Add ability to configure maximum number of threads for Jetty (having too low of a value for this setting on systems with large numbers of cores could prevent Jetty from handling requests).

1.4.0

PuppetDB 1.4.0 is a new feature release.

Notable features and improvements:

• (#21732) Allow SSL configuration based on Puppet PEM files (Chris Price & Ken Barber)

  This feature introduces some functions for reading keys and certificates from PEM files, and dynamically constructing java KeyStore instances in memory without requiring a .jks file on disk.

  It also introduces some new configuration options that may be specified in the jetty section of the PuppetDB config to initialize the web server SSL settings based on your Puppet PEM files.

  The tool puppetdb-ssl-setup has been modified now to handle these new parameters, but leave legacy configuration alone by default.

• (#20801) allow / wildcard (Marc Fournier)

  This allows you to use the default "Accept: /" header to retrieve JSON documents from PuppetDB without needed the extra "Accept: applicaiton/json" header when using tools such as curl.

• (#15369) Terminus for use with puppet apply (Ken Barber)

  This patch provides a new terminus that is suitable for facts storage usage with masterless or puppet apply usage. The idea is that it acts as a fact cache terminus, intercepting the first save request and storing the values in PuppetDB.

• Avoid Array#find in Puppet::Resource::Catalog::Puppetdb#find_resource (Aman Gupta)

  This patch provides performance improvements in the terminus, during the synthesize_edges stage. For example, in cases with 10,000 resource (with single relationships) we saw a reduction from 83 seconds to 6 seconds for a full Puppet run after this patch was applied.

• Portability fixes for OpenBSD (Jasper Lievisse Adriaanse)

  This series of patches from Jasper improved the scripts in PuppetDB so they are more portable to BSD based platforms like OpenBSD.

• Initial systemd service files (Niels Abspoel)

• Updated spec file for suse support (Niels Abspoel)

  This change wil make puppetdb rpm building possible on opensuse with the same spec file as redhat.

• (#21611) Allow rake commands to be ran on Ruby 2.0 (Ken Barber)

  This allows rake commands to be ran on Ruby 2.0, for building on Fedora 19 to be made possible.

• Add puppetdb-anonymize tool (Ken Barber)

  This patch adds a new tool 'puppetdb-anonymize' which provides users with a way to anonymize/scrub their puppetdb export files so they can be shared with third parties.

• (#21321) Configurable SSL protocols (Deepak Giridharagopal)

  This patch adds an additional configuration option, ssl-protocols, to the [jetty] section of the configuration file. This lets users specify the exact list of SSL protocols they wish to support, such as in cases where they're running PuppetDB in an environment with strict standards for SSL usage.

  If the option is not supplied, we use the default set of protocols enabled by the local JVM.

• Create new conn-lifetime setting (Chuck Schweizer & Deepak Giridharagopal)

  This creates a new option called conn-lifetime that governs how long idle/active connections stick around.

• (#19174) Change query parameter to optional for facts & resources (Ken Barber)

  Previously for the /v2/facts and /v2/resources end-point we had documented that the query parameter was required, however a blank query parameter could be used to return all data, so this assertion wasn't quite accurate. However one could never really drop the query parameter as it was considered mandatory and without it you would get an error.

  To align with the need to return all results at times, and the fact that making a query like '/v2/facts?query=' to do such a thing is wasteful, we have decided to drop the mandatory need for the 'query' parameter.

  This patch allows 'query' to be an optional parameter for /v2/facts & resources by removing the validation check and updating the documentation to reflect this this new behaviour.

  To reduce the risk of memory bloat, the settings resource-query-limit still apply, you should use this to set the maximum amount of resources in a single query to provide safety from such out of memory problems.

Bug fixes:

• Fix the -p option for puppetdb-export/import (Ken Barber)

• Capture request metrics on per-url/per-path basis (Deepak Giridharagopal)

  When we migrated to versioned urls, we didn't update our metrics middleware. Originally, we had urls like /resources, /commands, etc. We configured the metrics middlware to only take the first component of the path and create a metric for that, so we had metrics that tracked all requests to /resources, /commands, etc. and all was right with the world.

  When we moved to versioned urls, though, the first path component became /v1, /v2, etc. This fix now allows the user to provide full URL paths to query specific end-points, while still supporting the older mechanism of passing 'commands', 'resources', and 'metrics'.

• (21450) JSON responses should be UTF-8 (Deepak Giridharagopal)

  JSON is UTF-8, therefore our responses should also be UTF-8.

Other important changes & refactors:

• Upgrade internal components, including clojure (Deepak Giridharagopal)

  • upgrade clojure to 1.5.1
  • upgrade to latest cheshire, nrepl, libs, tools.namespace, clj-time, jmx, ring, at-at, ring-mock, postgresql, log4j

• Change default db conn keepalive to 45m (Deepak Giridharagopal)

  This better matches up with the standard firewall or load balancer idle connection timeouts in the wild.

1.3.2

PuppetDB 1.3.2 is a bugfix release. Many thanks to the following people who contributed patches to this release:

• Chris Price

Bug fixes:

• Size of column puppet_version in the database schema is insufficient

  There is a field in the database that is used to store a string representation of the puppet version along with each report. Previously, this column could contain a maximum of 40 characters, but for certain builds of Puppet Enterprise, the version string could be longer than that. This change simply increases the maximum length of the column.

1.3.1

PuppetDB 1.3.1 is a bugfix release. Many thanks to the following people who contributed patches to this release:

• Chris Price
• Deepak Giridharagopal
• Ken Barber
• Matthaus Owens
• Nick Fagerlund

Bug fixes:

• (#19884) Intermittent SSL errors in Puppet master / PuppetDB communication

  There is a bug in OpenJDK 7 (starting in 1.7 update 6) whereby SSL communication using Diffie-Hellman ciphers will error out a small percentage of the time. In 1.3.1, we've made the list of SSL ciphers that will be considered during SSL handshake configurable. In addition, if you're using an affected version of the JDK and you don't specify a legal list of ciphers, we'll automatically default to a list that does not include the Diffie-Hellman variants. When this issue is fixed in the JDK, we'll update the code to re-enable them on known good versions.

• (#20563) Out of Memory error on PuppetDB export

  Because the puppetdb-export tool used multiple threads to retrieve data from PuppetDB and a single thread to write the data to the export file, it was possible in certain hardware configurations to exhaust all of the memory available to the JVM. We've moved this back to a single-threaded implementation for now, which may result in a minor performance decrease for exports, but will prevent the possibility of hitting an OOM error.

• Don't check for newer versions in the PE-PuppetDB dashboard

  When running PuppetDB as part of a Puppet Enterprise installation, the PuppetDB package should not be upgraded independently of Puppet Enterprise. Therefore, the notification message that would appear in the PuppetDB dashboard indicating that a newer version is available has been removed for PE environments.

1.3.0

Many thanks to the following people who contributed patches to this release:

• Branan Purvine-Riley
• Chris Price
• Deepak Giridharagopal
• Ken Barber
• Matthaus Owens
• Moses Mendoza
• Nick Fagerlund
• Nick Lewis

Notable features:

• Report queries

  The query endpoint experimental/event has been augmented to support a much more interesting set of queries against report data. You can now query for events by status (e.g. success, failure, noop), timestamp ranges, resource types/titles/property name, etc. This should make the report storage feature of PuppetDB much more valuable!

• Import/export of PuppetDB reports

  PuppetDB 1.2 added the command-line tools puppetdb-export and puppetdb-import, which are useful for migrating catalog data between PuppetDB databases or instances. In PuppetDB 1.3, these tools now support importing and exporting report data in addition to catalog data.

Bug fixes:

• puppetdb-ssl-setup is now smarter about not overwriting keystore settings in jetty.ini during upgrades

• Add database index to status field for events to improve query performance

• Fix telnet protocol support for embedded nrepl

• Upgrade to newer version of nrepl

• Improvements to developer experience (remove dependency on rake for building/running clojure code)

1.2.0

Many thanks to following people who contributed patches to this release:

• Chris Price
• Deepak Giridharagopal
• Erik Dalén
• Jordi Boggiano
• Ken Barber
• Matthaus Owens
• Michael Hall
• Moses Mendoza
• Nick Fagerlund
• Nick Lewis

Notable features:

• Automatic node purging

  This is the first feature which allows data in PuppetDB to be deleted. The new node-purge-ttl setting specifies a period of time to keep deactivated nodes before deleting them. This can be used with the puppet node deactivate command or the automatic node deactivation node-ttl setting. This will also delete all facts, catalogs and reports for the purged nodes. As always, if new data is received for a deactivated node, the node will be reactivated, and thus exempt from purging until it is deactivated again. The node-purge-ttl setting defaults to 0, which disables purging.

• Import/export of PuppetDB data

  Two new commands have been added, puppetdb-export and puppetdb-import. These will respectively export and import the entire collection of catalogs in your PuppetDB database. This can be useful for migrating from HSQL to PostgreSQL, for instance.

  There is also a new Puppet subcommand, puppet storeconfigs export. This command will generate a similar export data from the ActiveRecord storeconfigs database. Specifically, this includes only exported resources, and is useful when first migrating to PuppetDB, in order to prevent failures due to temporarily missing exported resources.

• Automatic dead-letter office compression

  When commands fail irrecoverably or over a long period of time, they are written to disk in what is called the dead-letter office (or DLO). Until now, this directory had no automatic maintenance, and could rapidly grow in size. Now there is a dlo-compression-threshold setting, which defaults to 1 day, after which commands in the DLO will be compressed. There are also now metrics collected about DLO usage, several of which (size, number of messages, compression time) are visible from the PuppetDB dashboard.

• Package availability changes

  Packages are now provided for Fedora 18, but are no longer provided for Ubuntu 11.04 Natty Narwhal, which is end-of-life. Due to work being done to integrate PuppetDB with Puppet Enterprise, new pe-puppetdb packages are not available.

Bug fixes:

• KahaDB journal corruption workaround

  If the KahaDB journal, used by ActiveMQ (in turn used for asynchronous message processing), becomes corrupted, PuppetDB would fail to start. However, if the embedded ActiveMQ broker is restarted, it will cleanup the corruption itself. Now, PuppetDB will recover from such a failure and restart the broker automatically.

• Terminus files conflict between puppetdb-terminus and puppet

  There was a conflict between these two packages over ownership of certain directories which could cause the puppetdb-terminus package to fail to install in some cases. This has been resolved.

1.1.1

PuppetDB 1.1.1 is a bugfix release. It contains the following fixes:

• (#18934) Dashboard Inventory Service returns 404

  Version 1.1.0 of the PuppetDB terminus package contained a faulty URL for retrieving fact data for the inventory service. This issue is fixed and we've added better testing to ensure that this doesn't break again in the future.

• (#18879) PuppetDB terminus 1.0.5 is incompatible with PuppetDB 1.1.0

  Version 1.1.0 of the PuppetDB server package contained some API changes that were not entirely backward-compatible with version 1.0.5 of the PuppetDB terminus; this caused failures for some users if they upgraded the server to 1.1.0 without simultaneously upgrading the terminus package. Version 1.1.1 of the server is backward-compatible with terminus 1.0.5, allowing an easier upgrade path for 1.0.x users.

1.1.0

Many thanks to the following people who contributed patches to this release:

• Chris Price
• Deepak Giridharagopal
• Jeff Blaine
• Ken Barber
• Kushal Pisavadia
• Matthaus Litteken
• Michael Stahnke
• Moses Mendoza
• Nick Lewis
• Pierre-Yves Ritschard

Notable features:

• Enhanced query API

  A substantially improved version 2 of the HTTP query API has been added. This is located under the /v2 route. Detailed documentation on all the available routes and query language can be found in the API documentation, but here are a few of the noteworthy improvements:

  • Query based on regular expressions

    Regular expressions are now supported against most fields when querying against resources, facts, and nodes, using the ~ operator. This makes it easy to, for instance, find all IP addresses for a node, or apply a query to some set of nodes.

  • More node information

    Queries against the /v2/nodes endpoint now return objects, rather than simply a list of node names. These are effectively the same as what was previously returned by the /status endpoint, containing the node name, its deactivation time, as well as the timestamps of its latest catalog, facts, and report.

  • Full fact query

    The /v2/facts endpoint supports the same type of query language available when querying resources, where previously it could only be used to retrieve the set of facts for a given node. This makes it easy to find the value of some fact for all nodes, or to do more complex queries.

  • Subqueries

    Queries can now contain subqueries through the select-resources and select-facts operators. These operators perform queries equivalent to using the /v2/resources and /v2/facts routes, respectively. The information returned from them can then be correlated, to perform complex queries such as "fetch the IP address of all nodes with Class[apache]", or "fetch the operatingsystemrelease of all Debian nodes". These operators can also be nested and correlated on any field, to answer virtually any question in a single query.

  • Friendlier, RESTful query routes

    In addition to the standard query language, there are also now more friendly, "RESTful" query routes. For instance, /v2/nodes/foo.example.com will return information about the node foo.example.com. Similarly, /v2/facts/operatingsystem will return the operatingsystem of every node, or /v2/nodes/foo.example.com/operatingsystem can be used to just find the operatingsystem of foo.example.com.

    The same sort of routes are available for resources as well. /v2/resources/User will return every User resource, /v2/resources/User/joe will return every instance of the User[joe] resource, and /v2/nodes/foo.example.com/Package will return every Package resource on foo.example.com. These routes can also have a query parameter supplied, to further query against their results, as with the standard query API.

• Improved catalog storage performance

  Some improvements have been made to the way catalog hashes are computed for deduplication, resulting in somewhat faster catalog storage, and a significant decrease in the amount of time taken to store the first catalog received after startup.

• Experimental report submission and storage

  The 'puppetdb' report processor is now available, which can be used (alongside any other reports) to submit reports to PuppetDB for storage. This feature is considered experimental, which means the query API may change significantly in the future. The ability to query reports is currently limited and experimental, meaning it is accessed via /experimental/reports rather than /v2/reports. Currently it is possible to get a list of reports for a node, and to retrieve the contents of a single report. More advanced querying (and integration with other query endpoints) will come in a future release.

  Unlike catalogs, reports are retained for a fixed time period (defaulting to 7 days), rather than only the most recent report being stored. This means more data is available than just the latest, but also prevents the database from growing unbounded. See the documentation for information on how to configure the storage duration.

• Tweakable settings for database connection and ActiveMQ storage

  It is now possible to set the timeout for an idle database connection to be terminated, as well as the keep alive interval for the connection, through the conn-max-age and conn-keep-alive settings.

  The settings store-usage and temp-usage can be used to set the amount of disk space (in MB) for ActiveMQ to use for permanent and temporary message storage. The main use for these settings is to lower the usage from the default of 100GB and 50GB respectively, as ActiveMQ will issue a warning if that amount of space is not available.

Behavior changes:

• Messages received after a node is deactivated will be processed

  Previously, commands which were initially received before a node was deactivated, but not processed until after (for instance, because the first attempt to process the command failed, and the node was deactivated before the command was retried) were ignored and the node was left deactivated. For example, if a new catalog were submitted, but couldn't be processed because the database was temporarily down, and the node was deactivated before the catalog was retried, the catalog would be dropped. Now the catalog will be stored, though the node will stay deactivated. Commands received after a node is deactivated will continue to reactivate the node as before.

1.0.5

Many thanks to the following people who contributed patches to this release:

• Chris Price
• Deepak Giridharagopal

Fixes:

• Drop a large, unused index on catalog_resources(tags)

  This index was superseded by a GIN index on the same column, but the previous index was kept around by mistake. This should result in a space savings of 10-20%, as well as a possible very minor improvement in catalog insert performance.

1.0.4

Many thanks to the following people who contributed patches to this release:

• Chris Price

Fixes:

• (#16554) Fix postgres query for numeric comparisons

  This commit changes the regex that we are using for numeric comparisons in postgres to a format that is compatible with both 8.4 and 9.1.

1.0.3

NOTE: This version was not officially released, as additional fixes came in between the time we tagged this and the time we were going to publish release artifacts.

Many thanks to the following people who contributed patches to this release:

• Deepak Giridharagopal
• Nick Lewis
• Chris Price

Fixes:

• (#17216) Fix problems with UTF-8 transcoding

  Certain 5 and 6 byte sequences were being incorrectly transcoded to UTF-8 on Ruby 1.8.x systems. We now do two separate passes, one with iconv and one with our hand-rolled transcoding algorithms. Better safe than sorry!

• (#17498) Pretty-print JSON HTTP responses

  We now output more nicely-formatted JSON when using the PuppetDB HTTP API.

• (#17397) DB pool setup fails with numeric username or password

  This bug happens during construction of the DB connection pool. If the username or password is numeric, when parsing the configuration file they're turned into numbers. When we go to actually create the pool, we get an error because we're passing in numbers when strings are expected.

• (#17524) Better logging and response handling for version checks

  Errors when using the version endpoint are now caught, logged at a more appropriate log level, and a reasonable HTTP response code is returned to callers.

1.0.2

Many thanks to the following people who contributed patches to this release:

• Matthaus Owens

Fixes:

• (#17178) Update rubylib on debian/ubuntu installs

  Previously the terminus would be installed to the 1.8 sitelibdir for ruby1.8 or the 1.9.1 vendorlibdir on ruby1.9. The ruby1.9 code path was never used, so platforms with ruby1.9 as the default (such as quantal and wheezy) would not be able to load the terminus. Modern debian packages put version agnostic ruby code in vendordir (/usr/lib/ruby/vendor_ruby), so this commit moves the terminus install dir to be vendordir.

1.0.1

Many thanks to the following people who contributed patches to this release:

• Deepak Giridharagopal
• Nick Lewis
• Matthaus Litteken
• Chris Price

Fixes:

• (#16180) Properly handle edges between exported resources

  This was previously failing when an edge referred to an exported resource which was also collected, because it was incorrectly assuming collected resources would always be marked as NOT exported. However, in the case of a node collecting a resource which it also exports, the resource is still marked exported. In that case, it can be distinguished from a purely exported resource by whether it's virtual. Purely virtual, non-exported resources never appear in the catalog.

  Virtual, exported resources are not collected, whereas non-virtual, exported resources are. The former will eventually be removed from the catalog before being sent to the agent, and thus aren't eligible for participation in a relationship. We now check whether the resource is virtual rather than exported, for correct behavior.

• (#16535) Properly find edges that point at an exec by an alias

  During namevar aliasing, we end up changing the :alias parameter to 'alias' and using that for the duration (to distinguish "our" aliases form the "original" aliases). However, in the case of exec, we were bailing out early because execs aren't isomorphic, and not adding 'alias'. Now we will always change :alias to 'alias', and just won't add the namevar alias for execs.

• (#16407) Handle trailing slashes when creating edges for file resources

  We were failing to create relationships (edges) to File resources if the relationship was specified with a different number of trailing slashes in the title than the title of the original resource.

• (#16652) Replace dir with specific files for terminus package

  Previously, the files section claimed ownership of Puppet's libdir, which confuses rpm when both packages are installed. This commit breaks out all of the files and only owns one directory, which clearly belongs to puppetdb. This will allow rpm to correctly identify files which belong to puppet vs puppetdb-terminus.

1.0.0

The 1.0.0 release contains no changes from 0.11.0 except a minor packaging change.

0.11.0

Many thanks to the following people who contributed patches to this release:

• Kushal Pisavadia
• Deepak Giridharagopal
• Nick Lewis
• Moses Mendoza
• Chris Price

Notable features:

• Additional database indexes for improved performance

  Queries involving resources (type,title) or tags without much additional filtering criteria are now much faster. Note that tag queries cannot be sped up on PostgreSQL 8.1, as it doesn't have support for GIN indexes on array columns.

• Automatic generation of heap snapshots on OutOfMemoryError

  In the unfortunate situation where PuppetDB runs out of memory, a heap snapshot is automatically generated and saved in the log directory. This helps us work with users to much more precisely triangulate what's taking up the majority of the available heap without having to work to reproduce the problem on a completely different system (an often difficult proposition). This helps keep PuppetDB lean for everyone.

• Preliminary packaging support for Fedora 17 and Ruby 1.9

  This hasn't been fully tested, nor integrated into our CI systems, and therefore should be considered experimental. This fix adds support for packaging for ruby 1.9 by modifying the @plibdir path based on the ruby version. RUBY_VER can be passed in as an environment variable, and if none is passed, RUBY_VER defaults to the ruby on the local host as reported by facter. As is currently the case, we use the sitelibdir in ruby 1.8, and with this commit use vendorlibdir for 1.9. Fedora 17 ships with 1.9, so we use this to test for 1.9 in the spec file. Fedora 17 also ships with open-jdk 1.7, so this commit updates the Requires to 1.7 for fedora 17.

• Resource tags semantics now match those of Puppet proper

  In Puppet, tags are lower-case only. We now fail incoming catalogs that contain mixed case tags, and we treat tags in queries as case-insensitive comparisons.

Notable fixes:

• Properly escape resource query strings in our terminus

  This fixes failures caused by storeconfigs queries that involve, for example, resource titles whose names contain spaces.

• (#15947) Allow comments in puppetdb.conf

  We now support whole-line comments in puppetdb.conf.

• (#15903) Detect invalid UTF-8 multi-byte sequences

  Prior to this fix, certain sequences of bytes used on certain versions of Puppet with certain versions of Ruby would cause our terminii to send malformed data to PuppetDB (which the daemon then properly rejects with a checksum error, so no data corruption would have taken place).

• Don't remove puppetdb user during RPM package uninstall

  We never did this on Debian systems, and most other packages seem not to as well. Also, removing the user and not all files owned by it can cause problems if another service later usurps the user id.

• Compatibility with legacy storeconfigs behavior for duplicate resources

  Prior to this commit, the puppetdb resource terminus was not setting a value for "collector_id" on collected resources. This field is used by puppet to detect duplicate resources (exported by multiple nodes) and will cause a run to fail. Hence, the semantics around duplicate resources were ill-specified and could cause problems. This fix adds code to set the collector id based on node name + resource title + resource type, and adds tests to verify that a puppet run will fail if it collects duplicate instances of the same resource from different exporters.

• Internal benchmarking suite fully functional again

  Previous changes had broken the benchmark tool; functionality has been restored.

• Better version display

  We now display the latest version info during daemon startup and on the web dashboard.

0.10.0

Many thanks to the following people who contributed patches to this release:

• Deepak Giridharagopal
• Nick Lewis
• Matthaus Litteken
• Moses Mendoza
• Chris Price

Notable features:

• Auto-deactivation of stale nodes

  There is a new, optional setting you can add to the [database] section of your configuration: node-ttl-days, which defines how long, in days, a node can continue without seeing new activity (new catalogs, new facts, etc) before it's automatically deactivated during a garbage-collection run.

  The default behavior, if that config setting is ommitted, is the same as in previous releases: no automatic deactivation of anything.

  This feature is useful for those who have a non-trivial amount of volatility in the lifecycles of their nodes, such as those who regularly bring up nodes in a cloud environment and tear them down shortly thereafter.

• (#15696) Limit the number of results returned from a resource query

  For sites with tens or even hundreds of thousands of resources, an errant query could result in PuppetDB attempting to pull in a large number of resources and parameters into memory before serializing them over the wire. This can potentially trigger out-of-memory conditions.

  There is a new, optional setting you can add to the [database] section of your configuration: resource-query-limit, which denotes the maximum number of resources returnable via a resource query. If the supplied query results in more than the indicated number of resources, we return an HTTP 500.

  The default behavior is to limit resource queries to 20,000 resources.

• (#15696) Slow query logging

  There is a new, optional setting you can add to the [database] section of your configuration: log-slow-statements, which denotes how many seconds a database query can take before the query is logged at WARN level.

  The default behavior for this setting is to log queries that take more than 10 seconds.

• Add support for a --debug flag, and a debug-oriented startup script

  This commit adds support for a new command-line flag: --debug. For now, this flag only affects logging: it forces a console logger and ensures that the log level is set to DEBUG. The option is also added to the main config hash so that it can potentially be used for other purposes in the future.

  This commit also adds a shell script, puppetdb-foreground, which can be used to launch the services from the command line. This script will be packaged (in /usr/sbin) along with the puppetdb-ssl-setup script, and may be useful in helping users troubleshoot problems on their systems (especially problems with daemon startup).

Notable fixes:

• Update CONTRIBUTING.md to better reflect reality

  The process previously described in CONTRIBUTING.md was largely vestigial; we've now updated that documentation to reflect the actual, current contribution process.

• Proper handling of composite namevars

  Normally, as part of converting a catalog to the PuppetDB wire format, we ensure that every resource has its namevar as one of its aliases. This allows us to handle edges that refer to said resource using its namevar instead of its title.

  However, Puppet implements #namevar for resources with composite namevars in a strange way, only returning part of the composite name. This can result in bugs in the generated catalog, where we may have 2 resources with the same alias (because #namevar returns the same thing for both of them).

  Because resources with composite namevars can't be referred to by anything other than their title when declaring relationships, there's no real point to adding their aliases in anyways. So now we don't bother.

• Fix deb packaging so that the puppetdb service is restarted during upgrades

  Prior to this commit, when you ran a debian package upgrade, the puppetdb service would be stopped but would not be restarted.

• (#1406) Add curl-based query examples to docs

  The repo now contains examples of querying PuppetDB via curl over both HTTP and HTTPS.

• Documentation on how to configure PuppetDB to work with "puppet apply"

  There are some extra steps necessary to get PuppetDB working properly with Puppet apply, and there are limitations thereafter. The repo now contains documentation around what those limitations are, and what additional configuration is necessary.

• Upgraded testing during acceptance test runs

  We now automatically test upgrades from the last published version of PuppetDB to the currently-under-test version.

• (#15281) Added postgres support to acceptance testing

  Our acceptance tests now regularly run against both the embedded database and PostgreSQL, automatically, on every commit.

• (#15378) Improved behavior of acceptance tests in single-node environment

  We have some acceptance tests that require multiple nodes in order to execute successfully (mostly around exporting / collecting resources). If you tried to run them in a single-node environment, they would give a weird ruby error about 'nil' not defining a certain method. Now, they will be skipped if you are running without more than one host in your acceptance test-bed.

• Spec tests now work against Puppet master branch

  We now regularly and automatically run PuppetDB spec tests against Puppet's master branch.

• Acceptance testing for RPM-based systems

  Previously we were running all of our acceptance tests solely against Debian systems. We now run them all, automatically upon each commit against RedHat machines as well.

• Added new rake version task

  Does what it says on the tin.
