- add possibility to pass custom Error-Message AVP to negative diameter
answers
- negative answer is now built only when an error occurs
- remove tests that were testing behaviour with max concurrent requests 0
- add integration test specific to this change
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
Set redisPoolPipelineWindow to control duration before pipeline
flush (0 disables implicit pipelining) and redisPoolPipelineLimit
for max commands per pipeline (0 means no limit, only time window
applies).
Additional changes:
- removed unnecessary locking when initializing the exporter
cache map, as the service itself is responsible for locking.
- separated setupCache method into ClearExporterCache and
SetupExporterCache methods.
- removed idle ListenAndServe function that was only waiting for the
stopChan to close. The reload case was unreachable due to the reload
channel being created in Start instead of being passed down.
- removed Shutdown method on EventExporterS and replaced it with the
exported ClearExporterCache method as it provided the same
functionality.
Make use of the previously added ees_success_ids and ees_failed_ids
configuration fields.
Remove Processed opts and everything related to them since they should
not be used anymore.
Fixed test compilation errors caused by the change.
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.
Add StorDB to config and services.
Put back the store_cdrs option under cdrs and update the CDRs
service to depend on StorDB.
Define the StorDB interface and add a constructor for it.
Add a constructor for postgres storage.
Add a config sanity check to validate SSL modes for postgres.
Update cgr-engine to consider StorDB on startup.
