CPU profiling changes:
cgr-engine.go:
- use filepath.Join instead of path.Join
- handle *CoreService.StopCPUProfiling error inside deferred function
- same with the error from *os.File.Close()
cores/core.go:
- StartCPUProfile now returns an *os.File (as opposed to an io.WriteCloser),
because os.File.Stat is used beforehand to check if a handler of the file is
already active and confirm the status of profiling. Asserting the type would
have worked as well.
- handle pprof.StartCPUProfile error and ensure file is closed before returning
- log file close error as a warning if it occurs
- return missing mandatory error with correct path field name ('DirPath')
- no need to check if fileCPU is nil for profiling status
- pprof.StartCPUProfiling will return an error if profiling is already started
- os.File.Close() will return ErrClosed if profiling is already stopped
- differentiate between calling StopCPUProfiling when profiling hasn't started
and when it was already stopped by returning appropriate errors
Memory profiling changes:
- merge StopChanMemProf with StopMemoryProfiling
- remove fileMEM and stopMemProf from struct and constructors
- add separate mutex for memory profiling, ensure thread safety
- handle all significant errors
- log error if StopMemoryProfiling fails during CoreS Shutdown
- ignore errors if profiling inactive in Shutdown and deferred Stop
- move validations inside V1 functions
- return error if StartMemoryProfiling already started
- return error if StopMemoryProfiling already stopped or never started
- close profiling loop on error, not the cgr-engine
- StopMemoryProfiling closes channel and profiling loop writes final profile
- rename Path to DirPath for mandatory field error
- rename memprof_nrfiles flag to memprof_maxfiles
- increase default memprof_interval
- consider MaxFiles <= 0 as unlimited
- move memory profiling logic after starting services
- use CoreService Start/StopMemoryProfiling in main
- remove final memory profile block (created by deferred Stop)
- convert MemProfiling to method on CoreService and rename to profileMemory
- use Ticker for recurrent actions instead of Timer
- compute mem_final.prof full path in StartMemoryProfiling
- suffix profile files with current time instead of numbers
- update dispatcher methods after changes
- move MemoryPrf from utils to cores, rename to MemoryProfilingParams
- add logs for starting/stopping profiling
- added the possibility to disable timestamps in the memory profile file names
and use increments of 1 instead.
Other changes:
- improved integration tests for flags (now table tests)
- improved profiling integration tests
- Updated to use the test suite
- Deleted kafka_ssl sample configuration (moved to test file)
- Revised Kafka server SSL setup comment
- Ensured exporters are synchronous to avoid missing errors
- Implemented helper function to create and clean up kafka topics
- ERs sometimes took too long to receive a message.
Setting kafkaGroupID to "" prevents this.
- Kafka reader took 10s to close (default MaxWait).
Set MaxWait to 1ms.
- Exporters took 1s each to export due to BatchSize
not being hit. Set BatchSize to 1 to prevent it.
- renamed parameter type: ArgsReplyFailedPosts -> ReplayEventsParams
- renamed param fields:
- FailedRequestsInDir -> SourcePath
- FailedRequestsOutDir -> FailedPath
- TypeProvider -> Provider
- changed param fields types from *string to string
- used the SourcePath and FailedPath params directly instead of creating separate variables
- used filepath.WalkDir instead of reading the directory and looping over the entries
- used slices.ContainsFunc to check if the file belongs to any module (if 1+ is specified)
- used filepath.Join instead of path.Join
- used the path provided by WalkFunc instead of building the file paths ourselves
- made error returns more descriptive
- added logs for directories/files that are skipped
- paths that cannot be accessed are skipped after logging the error
They were failing after the ERs structure changes.
Added a commented helper program at the end of the test to
help generate credentials for testing nats JWT functionality
Moved engine/cdr.go to utils/cdr.go.
Moved engine/cdrs.go and engine/cdrs_test.go to cdrs package.
Moved api functions from cdrs/cdrs.go to cdrs/apis.go. Same for the
tests.
Deleted CDRsV1 type and its methods.
