             Bug #: 15346
           Summary: getdate() doesn't ignore trailing whitespaces
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: siddhesh@redhat.com
        ReportedBy: siddhesh@redhat.com
                CC: drepper.fsp@gmail.com
    Classification: Unclassified


The POSIX description of getdate says that:

"Extra whitespace in either the template file or in string shall be ignored."

but it does not.

Steps to Reproduce:

$ cat > tfile
%M
^D
$ cat > date.c
#define _GNU_SOURCE 500
#include <time.h>
#include <stdio.h>
#include <stdlib.h>

int
main (int argc, char *argv[])
{
  struct tm *tmp;
  int j;

  for (j = 1; j < argc; j++)
    {
      tmp = getdate (argv[j]);

      if (tmp == NULL)
        {
          printf ("Call %d failed; getdate_err = %d\n", j, getdate_err);
          continue;
        }

      printf ("Call %d (\"%s\") succeeded:\n", j, argv[j]);
      printf ("    tm_sec   = %d\n", tmp->tm_sec);
      printf ("    tm_min   = %d\n", tmp->tm_min);
      printf ("    tm_hour  = %d\n", tmp->tm_hour);
      printf ("    tm_mday  = %d\n", tmp->tm_mday);
      printf ("    tm_mon   = %d\n", tmp->tm_mon);
      printf ("    tm_year  = %d\n", tmp->tm_year);
      printf ("    tm_wday  = %d\n", tmp->tm_wday);
      printf ("    tm_yday  = %d\n", tmp->tm_yday);
      printf ("    tm_isdst = %d\n", tmp->tm_isdst);
    }

  exit (EXIT_SUCCESS);
}
^D
$ gcc date.c
$ DATEMSK=tfile ./a.out '1 '

Actual Result:

Call 1 failed; getdate_err = 7

Expected Result:

Call 1 ("1 ") succeeded:
    tm_sec   = 0
    tm_min   = 1
    tm_hour  = 0
    tm_mday  = 9
    tm_mon   = 3
    tm_year  = 113
    tm_wday  = 2
    tm_yday  = 98
    tm_isdst = 0
