This bug affects also gsview as you can't open attachment 1516 [details] with gsview 4.7.
On my copy of WinXP Pro, I am unable to create a file called: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaatige r.eps I can create file whose name is three characters shorter. The longest file name that I am able to handle with Ghostcript (CVS head) from the command line seems to be 202 characters. Note: gp_file_name_sizeof is defined as 260. I do not know why we cannot handle file names between 202 and 260 characters. >This bug affects also gsview as you can't open attachment 1516 [details] with gsview 4.7. I can open attachment 1516 [details] without problem with 8.51 from the command line. > This bug affects also gsview as you can't open attachment 1516 [details] with gsview 4.7.
GSview 4.7 can open files with names up to 255 characters long.
Note that the file name length includes the path.

patch
Increade the limit on the .libfile operand length from 200 to the full
gp_file_name_sizeof .
The file system also limits the length of the file name. I used the following
simple program to test the file systems and run time libraries.
#include <stdio.h>
#include <stdlib.h>
int main()
{ int i;
char buf[1024];
for(i=200; i < sizeof(buf); i++)
{ FILE *f;
printf("%d\n",i);
memset(buf, 'a', i);
buf[i] = 0;
f = fopen(buf, "wb");
if(!f)
break;
fclose(f);
}
return 0;
}
The results:
WindowsNT, NTFS, GCC = 243
WindowsNT, NTFS, MSVC = 252
WindowsNT, Samba, GCC = 236, last 5 files cannot be opened on Windows
WindowsNT, Samba, MSVC= 232, last 3 files cannot be opened on Windows
GNU+Linux, ext2, GCC = 255
The patch is committed to the HEAD branch. |
