I will install "minimum versions" of postgres and firebird if you guys decide to proceed with the byte count. Post what you want tested.

>> (or 4GiB if we change it to unsigned)

I think you should be very careful with that because php does not have unsigned integers.

>>> PHP_INT_MAX+1
2147483648

>>> (int) (PHP_INT_MAX+1)
-2147483648

And for completeness:

>>> (int) (PHP_INT_MAX+10000000000000000)
-272564224

Case in point:

>>> system('ls -l /huge')
rw-rr- 2 pie pie 2679696628 Apr 2 19:54 /huge
>>> filesize('/huge')
-1615270668

It would work like this, but we cannot extend it beyond the 4GiB limit on 32-bit, because filesize() returns an integer.

afischer@miraculix:~$ echo "<?php var_dump(PHP_INT_MAX);" | php

int(2147483647)

afischer@miraculix:~$ echo "<?php var_dump(filesize('LinuxMCE-8.10-beta2.iso'));" | php

int(-400189440)

afischer@miraculix:~$ echo "<?php var_dump((float) sprintf('%u', filesize('LinuxMCE-8.10-beta2.iso')));" | php

float(3894777856)

If there is an overflow somewhere, please create a new ticket. However, if there is one the issue is kind of slim because PHP also limits the actual upload size.

All right. I pushed the change I intend to make.

It would have to be tested on PostgreSQL 7.3 and Firebird 2.1. Those are the minimum requirements as per the INSTALL.html.

Thanks for testing.
