[gmediaserver-devel] File size limit

[Jan Ceuleers]

All,

I'm running into the dreaded 2GB file size limit that is often mentioned 
on the interweb, but rarely attributed to a specific cause.

What I'm trying to do is serve a large .avi file. This file is discarded 
in scan_entry() because it thinks that the stat() call there returns a 
negative value (and the error message is " cannot stat: Value too large 
for defined data type").

However, if I strace the process, the stat64() call actually returns zero:

stat64("/home/storage/Test/Eragon-001.avi", {st_mode=S_IFREG|0644, 
st_size=2200526492, ...}) = 0
open("/usr/share/locale/en_US.UTF-8/LC_MESSAGES/libc.mo", O_RDONLY) = -1 
ENOENT(No such file or directory)
open("/usr/share/locale/en_US.utf8/LC_MESSAGES/libc.mo", O_RDONLY) = -1 
ENOENT (No such file or directory)
open("/usr/share/locale/en_US/LC_MESSAGES/libc.mo", O_RDONLY) = -1 
ENOENT (No such file or directory)
open("/usr/share/locale/en.UTF-8/LC_MESSAGES/libc.mo", O_RDONLY) = -1 
ENOENT (No such file or directory)
open("/usr/share/locale/en.utf8/LC_MESSAGES/libc.mo", O_RDONLY) = -1 
ENOENT (No such file or directory)
open("/usr/share/locale/en/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT 
(No such file or directory)
open("/usr/share/locale-langpack/en_US.UTF-8/LC_MESSAGES/libc.mo", 
O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/share/locale-langpack/en_US.utf8/LC_MESSAGES/libc.mo", 
O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/share/locale-langpack/en_US/LC_MESSAGES/libc.mo", O_RDONLY) = 
-1 ENOENT (No such file or directory)
open("/usr/share/locale-langpack/en.UTF-8/LC_MESSAGES/libc.mo", 
O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/share/locale-langpack/en.utf8/LC_MESSAGES/libc.mo", O_RDONLY) 
= -1 ENOENT (No such file or directory)
open("/usr/share/locale-langpack/en/LC_MESSAGES/libc.mo", O_RDONLY) = -1 
ENOENT (No such file or directory)
write(2, "gmediaserver: /home/storage/Test"..., 100gmediaserver: 
/home/storage/Test/Eragon-001.avi: cannot stat: Value too large for 
defined data type
) = 100

So, is this a glibc problem?

Some system info:

Mine is a modified gmediaserver based on 0.11.0, but I think that the 
current stock release would exhibit the same problem.

Any thoughts?

Thanks, Jan
