[Octave-bug-tracker] [bug #57439] handles to private functions may fail after "clear functions"

[Rik]

Follow-up Comment #48, bug #57439 (project octave):

Benchmarking shows that access() is about 8% slower than stat() on my
machine.

Test code for stat() in stat_bm.cpp:


//#include <iostream>
#include <string>

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

using namespace std;

int main()
{
   const int LOOPMAX = 1e7;
   const string path = "/home/rik/wip/Projects_Mine/octave-dev/afun.m";

   int retval;
   struct stat statbuf;
   for (int i = 0; i < LOOPMAX; i++)
     {
        retval = stat (path.c_str (), &statbuf); 
//        cout << retval << "\n";
     }
}


Compiling and using "time ./stat_bm" shows an average running time of 11.8 (5
replicates).

Test code for access in access_bm.cpp:


//#include <iostream>
#include <string>
#include <unistd.h>

using namespace std;

int main()
{
   const int LOOPMAX = 1e7;
   const string path = "/home/rik/wip/Projects_Mine/octave-dev/afun.m";

   int retval;
   for (int i = 0; i < LOOPMAX; i++)
     {
        retval = access (path.c_str (), F_OK); 
//        cout << retval << "\n";
     }
}



Same timing procedure yielded an average running time of 12.8.
