I think that's because it's sending it in JSON as "in_experiment" rather than "inExperiment" as we expect to parse it. * fixing ruby logic causing ih failures (#152) * fixing ruby logic * adding missing spec * Apply suggestions from code review Co-authored-by: Sam Stokes <sstokes@launchdarkly.com> * pr tweaks * making spec language consistent Co-authored-by: Sam Stokes <sstokes@launchdarkly.com> * add log warning for missing user key (#153) * add log warnings for nil/empty user key * rm warning for empty string key * fix test * diagnostic events should respect HTTPS_PROXY (#154) * minor test simplification (#155) * allow higher minor versions of json and http gems * allow v5.x of http gem (#157) * use Bundler 2.2.10 + modernize CI config (#158) * enable verbose rspec output * fix socket factory tests * restore log suppression * Replacing deprecated circleci image usage (#159) * use Releaser v2 config (#161) * Updates docs URLs * Update lib/ldclient-rb/ldclient.rb Co-authored-by: Louis Chan <91093020+louis-launchdarkly@users.noreply.github.com> * remove reliance on git in gemspec (#163) * use ruby-eventsource 2.1.1 for fix of sc-123850 and sc-125504 (#164) * use ruby-eventsource 2.1.1 for fix of sc-123850 and sc-125504 * comment phrasing * Start work on flag builder. * Add user targeting and rule builder * Add datasource implementation * Convert the current_flags hash to use symbols instead of strings as keys * Fix typo on FlagRuleBuilder copy constructor * minor refactoring of impl; Added use of new Clause struct instead of Hash in FlagRuleBuilder; Moved TestData.factory out of Impl namespace and renamed Impl to TestDataImpl * Add the doc comments * (big segments 1) add public config/interface/reason types (#167) * Cleanup docstrings to be YARD docs * Added Util.is_bool helper function to clean up the check for whether an object is a boolean; Removed the DeepCopyHash/DeepCopyArray objects in favor of deep_copy_hash and deep_copy_array functions * Move public classes out of Impl namespace.

This brings the configuration up to date with the latest naming conventions. * Add windows tests in circleci (#199) At some point in the past, we were experimenting with using Azure to verify Window builds. Now that CircleCI supports Windows, we should keep everything on a single CI provider. * Add application info support (#194) * reuse EvaluationDetail instances by precomputing results * rubocop reformatting * add super constructor calls * disable rubocop Rails rules and fix some remaining syntax offenses * fix super calls * Add big segment support to contract tests (#201) * Initial creation of LDContext (#206) This introduces the initial structure and usage of the LDContext class. Instances of this class are expected to be created through static factory methods: ```ruby LaunchDarkly::LDContext.create({...}) LaunchDarkly::LDContext.create_multi([...]) ``` This class is not completed yet. Rather, this initial commit is focused on the creation patterns and the most basic operations. Subsequent commits will continue fleshing out this class and its operation. The `get_value` method will see significant changes as we introduce attribute reference support. Its current more simplistic implementation exists only to serve some interim unit tests. * Add reference based value retrieval (#207) This commit introduces the References type used for targeting complex attributes in the new LDContexts. References are expected to be created through static factory methods: ```ruby LaunchDarkly::Reference.create("/a/b") LaunchDarkly::Reference.create_literal("/a/b") ``` These references can be used to retrieve values from an existing LDContext ```ruby ref = LaunchDarkly::Reference.create("/a/b") result = context.get_value_for_reference(ref) ``` * Basic changes to use contexts in evaluations instead of users (#208) This commit follows the general approach of the [equivalent PHP SDK PR][pr]. This replaces `LDUser` with `LDContext` in the parameters for evaluations, and makes the minimum necessary adjustments to allow evaluations to keep working as before as long as the context kind is "user". None of the new behavior defined in the U2C spec is implemented yet. Generation of evaluation events is temporarily disabled because the event logic hasn't been updated yet. U2C contract tests for evaluations are partially enabled; a lot of functionality is still missing, but all the tests that only cover previously-existing evaluation behavior are passing. [pr]: launchdarkly/php-server-sdk-private#103 * Support ContextKind in Clauses (#209) This commit follows the general approach of the [equivalent PHP SDK PR][pr]. The main features of this commit are: - introduction of `individual_context` and `individual_context_count` methods - context kind matching in clauses [pr]: launchdarkly/php-server-sdk-private#108 * Support included / excluded contexts in segments (#210) This commit follows the general approach of the [equivalent PHP SDK PR][pr]. Segments are now able to provide `includedContext` and `excludedContext` properties which can target values within a specific context kind. ```json { "includedContexts": [ { "contextKind": "org", "values": ["orgkey1", "orgkey2"] } ] } ``` [pr]: launchdarkly/php-server-sdk-private#111 * Add contextKind support for rollouts & experiements (#211) This commit follows the general approach of the [equivalent PHP SDK PR][pr]. [pr]: launchdarkly/php-server-sdk-private#110 * Style and test matcher improvements (#212) This commit enables several rubocop rules that were previously disabled. Once enabled, `rubocop -A` was run to automatically apply these fixes. There are a couple of additional changes that were made by hand: - I added the rubocop and rubocop-performance gems as dev packages. This should help address the original installation issue we ran into when I introduced these tools. - By default, new rubocop rules are disabled. This was the default before, but if you don't explicitly set this value, each run generates a ton of warning noise. This quiets that down. - Updates some LDContext tests to be more strict in their expectations of truth. * Remove support for secondary attribute (#213) As decided in the [spec], we are removing the special behavior of the secondary attribute. Going forward, secondary will be treated like any other attribute, and will no longer be included when determining the bucket for a context. [spec]: https://launchdarkly.atlassian.net/wiki/spaces/ENG/pages/2165212563/Consistent+and+Transparent+Rollout+Behavior+Unifying+Percent+Rollout+and+Traffic+Allocation * Remove deprecated APIs (#214) Since the users to context change requires a version break, this is the perfect time to remove previously deprecated bits of functionality. This includes: - Removing `update_processor*` config entries - `FileDataSource` entry point - `RedisFeatureStore` entry point - `Redis::sadd?` warning in unit tests * store data model with classes that aren't Hash * lint * remove [] override methods in places where we don't need them * comments * migrate some more of the model to be non-hash classes * lint * Anonymous cannot be nil in new context format (#216) The legacy user format allowed anonymous to be missing or explicitly provided but set to nil. The new context format requires anonymous to either not be set, or if it is explicitly set, it must be a boolean value. * Tweak error message language and style (#217) Our previous error messages suffered from a couple drawbacks: - The messages were complete sentences, limiting our ability to compose error messages - The messages were overly broad in many cases - The messages unnecessarily required string interpolation that rarely provided much value These new messages are more succinct and are written as small clauses which can be used in conjunction with other error messages more easily. * copyedit Co-authored-by: Matthew M. Keeler <mkeeler@launchdarkly.com> * Implement prerequisite cycle detection (#219) * Support attribute reference lookups (#215) This adds support for slash-delimited paths in clause attributes, bucketBy, etc. It does not do anything related to private attribute redaction because none of the U2C event logic is implemented yet. * Implement segment recursion and cycle detection (#220) Clauses in segment rules are now allowed to reference segments. To prevent an infinite recursion edge case, we implement a similar cycle detection mechanism as used on prerequisites. * Update event logic to support users to context change (#221) * Add legacy user-type support to the contract tests (#222) * Remove inline user configuration option (#223) * Add context_ configuration options (#224) These new context_ configuration options are meant to replace the historic user_ options. If both are provided, the context_ variant will take precedence. * Add support for flag context targets (#225) * Bump diplomat * Bump redis * Remove oga * Bump connection_pool * Favor set for faster target lookups (#228) A few of our internal models maintain arrays of values. These arrays can frequently be checked to see if they contain specific values. Since set lookups are much faster than array lookups, this commit changes the internal structure to a set for the values stored in Target and SegmentTarget. * Add secure mode hash to contract tests (#229) * Update big segment support for users to context (#226) To support the users to context change for big segments, this commit makes the following changes: - Introduces a new `Segment.unboundedContextKind` attribute. This will default to `LDContext::KIND_DEFAULT` and is only referenced when `Segment.unbounded` is true. - With the creation of multi-kind contexts, a single evaluation may result in multiple queries to the big segment store. This is reflected in the changes to the `EvalResult` processing. * Drop support for ruby 2.6 (#227) Ruby 2.6 went EOL in March 2022. We originally didn't drop support for it as doing so would require dropping support for jRuby as well. However, jRuby recently released 9.4 which is Ruby 2.7+ compatible. * Update remaining references from user to contexts (#231) There are multiple places throughout the code where we are still referencing users. I have tried to update all the places where a rename seems reasonable or appropriate. There is still some work to do in the test flag builders, but that will be done in a subsequent commit. * Remove new relic integration (#233) The new relic integration was removed many versions ago but a small trace remained behind. * Rename config option private_attribute_names (#234) Co-authored-by: Eli Bishop <eli@launchdarkly.com> * Update test data integration to support contexts (#232) * improve data model validation logging; allow missing/empty attribute for segmentMatch (#236) * Fix JSON serialization failure (#237) When we introduced models for the flag and segment data, we added to_json methods which proxy to the underlying to_json method provided by the `json` gem. We defined the method with a variadic parameter, but we failed to unpack it when passing it on to the underlying implementation. This resulted in a serialization failure which prevented the redis data store from initializing. * fix: Bump eventsource to resolve header parsing (#239) The underlying event source library had an issue where, in certain environments, content-type header detection was failing. This was resolved in v2.2.2 of the event source gem. * Add key to error log for invalid context during variation call for easier debugging (#214) * feat: Add support for payload filtering (#238) * feat: Add data source status provider support (#240) The client instance will now provide access to a `data_source_status_provider`. This provider allows developers to retrieve the status of the SDK on demand, or asynchronously by registering listeners. * test: Skip database integration tests by default (#241) The full unit test suite includes tests relying on externally instances of Redis, Consult, and DynamoDB. By default, we do not want to run these tests. Rather, they should be opt-in by setting the environment variable `LD_SKIP_DATABASE_TESTS=0`. * feat: Introduce flag change tracker api (#242) The client instance will now provide access to a `flag_tracker`. This tracker allows developers to be notified when a flag configuration changes (or optionally when the /value/ of a flag changes for a particular context). * ci: Add code coverage generation (#244) * feat: Add support for data store status monitoring (#243) The client instance will now provide access to a `data_store_status_provider`. This provider allows developers to retrieve the data store status of the SDK on demand, or asynchronously by registering listeners. * Fix monitoring_enabled? access --------- Co-authored-by: Eli Bishop <eli@launchdarkly.com> Co-authored-by: LaunchDarklyCI <dev@launchdarkly.com> Co-authored-by: Jacob Smith <jacob@jacobsmith.io> Co-authored-by: Elliot <35050275+Apache-HB@users.noreply.github.com> Co-authored-by: Ben Woskow <bwoskow@launchdarkly.com> Co-authored-by: Ben Woskow <48036130+bwoskow-ld@users.noreply.github.com> Co-authored-by: hroederld <hroeder@launchdarkly.com> Co-authored-by: Kerrie Martinez <kyee@launchdarkly.com> Co-authored-by: pellyg-ld <gpelly@launchdarkly.com> Co-authored-by: Sam Stokes <sstokes@launchdarkly.com> Co-authored-by: LaunchDarklyReleaseBot <launchdarklyreleasebot@launchdarkly.com> Co-authored-by: Ember Stevens <ember.stevens@launchdarkly.com> Co-authored-by: ember-stevens <79482775+ember-stevens@users.noreply.github.com> Co-authored-by: Louis Chan <91093020+louis-launchdarkly@users.noreply.github.com> Co-authored-by: Matthew M.
