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
