Bug #53587 [NEW]: "Seek error: Invalid argument" when creating ZIP larger than 2GB on 32bit arch
From:
Operating system: Linux, Mac OS X
PHP version: 5.3.4
Package: *Compression related
Bug Type: Bug
Bug description:"Seek error: Invalid argument" when creating ZIP larger than 2GB on 32bit
arch
Description:
------------
On 32bit system, you can't generate ZIP files larger than 2GB.
I reproduce this with :
- PHP 5.3.4 on Mac OS 10.5 i686
Also observed with :
- PHP 5.2.4 on Ubuntu 8.04 i686
- PHP 5.3.2 on Ubuntu 10.04 i686
I tested with 3 files of 1GB random data. After adding the 3 files, the
$zip-
>close() returns the error "Seek error: Invalid argument" and there is no
zip
output file.
After looking into ext/zip, it seems that the problem is in the use of
"unsigned
long" types instead of the "off_t" type in zip_cdir struct, and the fact
that
the HAVE_FSEEKO and HAVE_FTELLO are not detected/defined by the ./configure
script.
On OS X (PHP 5.3.4), if I recompile the ext/zip extension by hand with the
patch
below (force HAVE_FSEEKO/HAVE_FTELLO and adjust the "unsigned long" to
"off_t"
in zip_cdir struct), then I can create my ZIP archive larger than 2GB.
Test script:
---------------
#!/bin/bash
# -- Create 3 files of 1GB random data
for I in 1 2 3; do dd if=/dev/urandom of=f$I bs=1M count=1024; done
# -- Create a 'out.zip' archive containing these 3 files
php -r '$zip = new ZipArchive(); $zip->open("out.zip", ZIPARCHIVE::CREATE);
$zip->addFile("f1"); $zip->addFile("f2");
$zip->addFile("f3"); $ret =
$zip->close(); if( $ret === false ) { print sprintf("Error: %s",
$zip->getStatusString()); };'
zip -T out.zip
if [ $? -ne 0 ]; then
echo "ERROR"
exit 1
fi
echo "OK"
exit 0
Expected result:
----------------
A ZIP archive with a size around 3GB that passes the `zip -T' verification.
Actual result:
--------------
$zip->close() returns false with error "Seek error: Invalid argument", and
the ZIP
output file is not produced.
