Revisiting Memory tracking :

  • MemTrack? has been improved
    • Not need anymore to use private external libaddr2line, fork addr2line process internaly and use bidrectionnale pipe to send stack adress et get in return the demangle stack name
    • Can use cxa_demangle in backup
  • Block memory leak report is output in separate file (xios_xxx.mem),memory block are ordonned in decreasing size.
  • Possibility to output only the n bigest bloc with : "memtrack_blocs" xios parameters
  • Possibility to output only bloc over a given size with : "memtrack_size" xios parameters
  • Implement new method to retrieve the memory consumed in a time interval very similarely to xios timer :

CMemTracker("xios").resume()
CMemTracker("xios").suspend() ;
etc....
