ConfigProvider iterates over all sources and reports all non-null values to telemetry (#9404)
* apply all changes from PR #9327, accomodated to master * nits: add configId in ConfigProvider methods where it was missing; fix configId test to accommodate new ConfigCollector data structure * Fix 'test config id exists in ConfigCollector when using StableConfigSource' * introduce reportDefault * Call collect in BaseApplication.getLogInjectionEnabled; make getAppliedConfigSetting static function that takes in a map * Fix call to getAppliedConfigSetting in ConfigCollector test * Introduce ConfigValueResolver and ConfigMergeResolver * getString methods only report non-null values to telemetry * remove dependency on collectConfig for reReportToCollector and reReportFinalResult * updating config collector to not override existing configs * Adding putDefault and adding unit tests * relaxing reReportToCollector restraint and adding unit test * cleanup * updating failing unit test * abstracing ConfigCollector * adding support for proper seqId with Remote Config * abstracting away getString * Update internal-api/src/main/java/datadog/trace/bootstrap/config/provider/ConfigProvider.java * Update internal-api/src/main/java/datadog/trace/bootstrap/config/provider/ConfigProvider.java * Update internal-api/src/main/java/datadog/trace/bootstrap/config/provider/ConfigProvider.java * nit: fix javadoc comments * Modify getEnum, getList, getIntegerRange and getSet to report defaults before calling getString. And modify putDefault to treat null entries as a valid value * remove remoteConfig methods from ConfigCollector + highestSeqId * remove serializenulls comment in TelemetryRequestBody * remove 'no usages' comment above unused ConfigCollector put method * Simplify javadoc for putAll * remove javadoc for ABSENT_SEQ_ID * revert getStringInternal changes * Introduce new getStringInternal, for getting string from non-default sources * Deprecate ConfigCollector constructor without sequence ID * putRemote: ConfigCollector method for 'putting' from Remote Config origin; migrate AppSecConfigServiceImpl to use this API * ConfigSetting.NON_DEFAULT_SEQ_ID: introduce new constant, migrate all calls to 'DEFAULT_SEQ_ID + 1' to use new constant; move constants to top of ConfigSetting class * ConfigCollector.put: Delete unused function * Update internal-api/src/test/groovy/datadog/trace/api/ConfigCollectorTest.groovy Co-authored-by: Stuart McCulloch <[email protected]> * replace 'def origin' assignment in ConfigCollectorTest with in-line use * ConfigCollector.put: Remove deprecated function with zero uses * NEW_SUB_MAP: Define reusable lambda function as static field in ConfigCollector, used by putDefault and put * updateAll: rename putAll to updateAll, and scope to Remote origin, only * Fix updateAll * Align naming of methods that report remote config to the ConfigCollector * Avoid need to peek into ConfigCollector internals * Restore atomic reporting of updates from remote-config * Update utils/config-utils/src/main/java/datadog/trace/bootstrap/config/provider/ConfigProvider.java Co-authored-by: Stuart McCulloch <[email protected]> * Update utils/config-utils/src/main/java/datadog/trace/bootstrap/config/provider/ConfigProvider.java Co-authored-by: Stuart McCulloch <[email protected]> * Update utils/config-utils/src/main/java/datadog/trace/bootstrap/config/provider/ConfigProvider.java Co-authored-by: Stuart McCulloch <[email protected]> * Fix bug in reReportFinalResult that incorrectly reported CALCULATED for all non-default values --------- Co-authored-by: Matthew Li <[email protected]> Co-authored-by: Stuart McCulloch <[email protected]>
