Summary

0002553: OutOfMemoryError in phpBB3 on database restore

Description

This is under WinXP with PhpBB 3.0.0.

In the Admin Control Panel, create a database backup of
all tables and store it with the gzip option selected.
Then, do a restore operation after selecting the backup
that was just created. This generates a OutOfMemoryError
with the following stack:

$module->load_active()
$this->module->main() (functions_module.php)
function main() (acp_database.php)

On line 323, the fgetd function is invoked to parse the contents
of the gzipped file. The JVM runs out of memory in the fgetd()
function (also defined in acp_database.php).

The file descriptor passed to this method was opened by bzopen(),
so it is likely that the combination of the bzip file and the
seek() operations in the fgetd() function are the cause of this
error.

A database backup/restore in plain text (not gzip) works as expected.

(0002917) mo 03-26-08 16:54	Looking into this bug uncovered a number of issues with gzseek: php/1v0z.qa php/1v19.qa php/1v18.qa A couple of file module APIs were also broken when dealing with write only files: php/161x.qa php/161y.qa php/161z.qa

(0002918) mo 03-26-08 16:59	Confirmed that this fixes restore from gzip backup functionality in phpBB3.
