Feat/poc continuous profiling (#4556)
* wip * re-add data category profile_chunk, fix json naming, new converter based on jfr converter bundled with asyncprofiler * read java thread ids from jfr and use those instead of os thread ids, use existing SentryStackFrame instead of JfrFrame, * adhere to sentry conventions re format null safety etc, fix compilation * add profile-session-sample-rate to external options * add platform as constructor param to ProfileChunk, wip: set java continuous profiler in sentry init * add doubleToBigDecimal in JfrSample and ProfileChunk, same as we do it in SentrySpan to work around scientific notation of double, use wall clock profiling * rename JfrProfile to SentryProfile * move java profiling into its own module, load using SPI * [WIP] use getProfilingTracesDirPath * add missing build.gradle.kts for profiler module * WIP continuous profiling in trace mode * cleanup unused classes from vendor, cleanup packages * allow setting profiling-traces-dir-path independently from cache dir using external options * use profileChunk.platform to decide how to deal with the chunk instead of file extension * port relevant AndroidContinuousProfilerTest tests to JavaContinuousProfilerTest * add service loader tests for profiler and profile converter * remove old jfr test files * Support ProfileLifecycle.TRACE (#4576) * delete unused JfrFrame and JfrToSentryProfileconverter * use passed-in profilingTracesHz parameter instead of hardcoded value * start profiler before starting the transaction when ProfileLifecycle.TRACE is used to have the profile ID when SentryTracer is created * use improved way to calculate timestamp of sample * api dump * let profile-lifecycle be set from external_options, add tests for SpringBoot autoconfig * initialize stackTraceFactory only once per chunk * rename profile data classes, add deserialization and tests * extract methods in ProfileConverter, fix SentryProfile serialization and make fields private * use wall=[interval] instead of setting the event to wall and setting the interval separately, this seems to work better and create more samples * start/stop profiler in OtelSentrySpanProcesser in trace mode for root spans * add profiler dependency to jakarta-opentelemetry sample, add needed configs * add dependenies and config to spring-boot-jakarta sample * remove connection status check * extract event visitor * Add enum for ProfileChunk platform * fallback to default temp directory for profiling on jvm if directory is not configured * cleanup some minor things * remove ProfilingInitializer, fix comments * Format code * add getter/setter to sample and metadata * fix compile error * add comment/todo for deleteOnExit * Profiling - Deduplication and cleanup (#4681) * add readme and info about commit of the source repository * delete jfr file on jvm exit * further split into smaller methods * deduplicate frames in order to save bandwidth, add converter tests * remove Platform Enum, use string constants instead for compatibility with cross platform frameworks * implement equals and hashcode for SentryStackFrame to make frame deduplication work * bump api * improve error handling, fix start stop start flow * add new testfile * calculate ticksPerNanosecond in constructor * adapt Ratelimiter to check for both ProfileChunk and ProfileChunkUi ratelimiting * update ratelimiter test to check for both profileChunk and profileChunkUi drops * use string constant instead of string * Format code * add non aggregating event collector to send each event individually, deduplicate stacks * adapt converter tests to new non-aggregated converter * Format code * add logging to loadProfileConverter * Format code * fix duplication of events * catch all exception happening when converting from jfr * add exists and writable info to log message * add method to safely delete file * remove setNative call * fix test * fix reference to commit we vendored from * drop event if it cannot be processed to not lose the whole chunk * make format * fix test * Format code * Profiling - OTEL profiling fix, Stabilization, Logging (#4746) * add skipProfiling flag to TransactionOptions to be able to skip profiling and handle cases where profiling has been started by otel * add profilerId to spanContext so that otel span processor can propagate this to the exporter and SentryTracer * immediately end profiling when stopProfiler is called * bump api, fix android api 24 code * catch all exception happening when converting from jfr * simplify JavaContinuous profiler by catching AsyncProfiler instantiation exceptions in provider * add exists and writable info to log message * add method to safely delete file * remove setNative call * fix test * fix reference to commit we vendored from * drop event if it cannot be processed to not lose the whole chunk * Format code * fix test * Format code * fix test * catch exceptions in startProfiler/stopProfiler * fallback to threadId -1 if it cannot be resolved --------- Co-authored-by: Sentry Github Bot <bot+github-bot@sentry.io> --------- Co-authored-by: Sentry Github Bot <bot+github-bot@sentry.io> --------- Co-authored-by: Sentry Github Bot <bot+github-bot@sentry.io> * change profiler api from Path to String to keep Android Api 21 compatibility * mark all profiling related classes as internal * Format code * mark Sentry profile classes internal * Format code * mark SentryThreadMetadata internal * add changelog entry * Format code * re-add asyncprofiler classes, cr changes * bump api * detect dangerous/invalid chars in profiling directory name * ignore vendored profile conversion code in codecov --------- Co-authored-by: Sentry Github Bot <bot+github-bot@sentry.io>
