Bug 1105 – std.c.linux.linux.stat fails for files > 2GB

While trying to use listdir (combined with isdir) on a folder containing files > 2GB I ran into a "Value too large for defined data type" FileException. Further inspection showed that a call to std.c.linux.linux.stat returns -1 on files > 2GB. I found that st_size is of type int in struct_stat. Testfall: dd if=/dev/zero of=/tmp/test.dat bs=100MB count=22 error.d: import std.file; void main(char[][] args) { isdir ("/tmp/test.dat"); }

This is a C issue. The below C code shows the same symbtoms like the above D code: # #include <sys/stat.h> # #include <stdio.h> # #include <errno.h> # # int main(){ # struct stat meta; # int code = stat("/tmp/test.dat", &meta); # # if(0 == code){ # printf("isdir: %i\n", S_ISDIR(meta.st_mode)); # }else{ # printf("errno: %i\n", errno); # } # # return 0; # } While this issue can be by-passed via stat64 (below) stat64 isn't guaranteed to be present (most current Linux system should support it but some odler ones don't): # #define _LARGEFILE64_SOURCE 1 # #include <sys/stat.h> # #include <stdio.h> # #include <errno.h> # # int main(){ # struct stat64 meta; # int code = stat64("/tmp/test.dat", &meta); # # if(0 == code){ # printf("isdir: %i\n", S_ISDIR(meta.st_mode)); # }else{ # printf("errno: %i\n", errno); # } # # return 0; # }

Created attachment 144 bigfile support for DMD-1.014's Phobos (mostly un-tested)

Created attachment 145 bzip2 compressed DMD-1.014 libphobos.a with bigfile support

changed to "duplicate" because Bugzilla's duplication statistic is rather limited and doesn't support lower numbered issue reports to be marked as duplicate of an higher numbered one *** This bug has been marked as a duplicate of 579 ***
