Export Events problem - creating empty files...

Post by Flasheart »

v1.24.2, Debian testing.

The data hard drive is dying and I would like to export the archived events before I install a replacement. Either in jpg or video, don't mind.

I select all the archive pics from the filter view, the thumbnails appear and I click 'Export' at the bottom.

I then tick all the boxes in the "Export Options" box and choose Tar as format. Click Export.

I get "Export Succeeded - Download", click download and receive a .tgz file.

Unfortunately, it's empty. Filesize of 54 bytes, just the tgz wrapper with no files inside it.

I've ensured /var/cache/zoneminder/temp is world-writeable, and it's creating two files in there ok;

cradle:/var/cache/zoneminder/temp# ls -l
total 4
-rw-r--r-- 1 www-data www-data 45 2010-08-19 12:12 zmExport.tar.gz
-rw-r--r-- 1 www-data www-data 0 2010-08-19 12:12 zmFileList.txt

But as you can see, zmFileList.txt is empty, suggesting something went wrong before tar and gzip got to work.

Can't find anything useful in the logs.

What have I missed?

(Tested same process on another server running 1.22.3 and that works fine)

The problem is that the behavior of array_merge changed in PHP5. Zoneminder's export function breaks.

The line in question is in /usr/share/zoneminder/skins/classic/includes/export_functions.php

$exportFileList = array_merge( $exportFileList, exportFileList( $eid ), $exportDetail, $exportFrames, $exportImages, $exportVideo, $exportMisc );

Various howtos suggest adding (array) before the variables. I've tried that and it fails for but not being a php coder I'm a bit hit and miss here.

Anyone fancy fixing this line to adhere to the php5 standards?

Single event export was broken too - in a different way. I've fixed that by some quick hackery;

Line 161 of /usr/share/zoneminder/skins/classic/includes/export_functions.php

Code: Select all

       $eventPath = getEventPath( $event );
	to
       $eventPath = '/data/' . getEventPath( $event );
Because /data/ is my zoneminder root path and for some reason this wasn't being prepended by the export function so it couldn't find the files.

After error_log entries of

PHP Warning: opendir(events/6/60109): failed to open dir: No such file or directory in /usr/share/zoneminder/skins/classic/includes/export_functions.php on line 163, referer:


Multiple exports are still broken for me as above, though.

hers what i would do.

install new drive(same size) leaving failing one in pc.
boot a live cd

run this dd if=/dev/olddrive of=/dev/newdrive

reboot

remove old drive and you should be good to go.

dd is a bit for bit low level copy.

Aye, although the disk size is different and a cp does the job too - but with 2tb drives this takes quite a while copying 99% of events that aren't needed.

Good thinking, but I would quite like to get exports running properly :)

Export Failed from Multiple Events Fixed

Post by amppjunior »

Hi, I had the same problem and have it fixed. Just modify line 255 from the file zm/skins/classic/includes/export_functions.php from:
$exportFileList = array_merge( $exportFileList, exportFileList( $eid ), $exportDetail, $exportFrames, $exportImages, $exportVideo, $exportMisc );
to:
$exportFileList = array_merge( $exportFileList, exportFileList( $eid , $exportDetail, $exportFrames, $exportImages, $exportVideo, $exportMisc ));

Good luck!

I'm now having this same problem when exporting a single event. The tar file downloads fine but it is empty.

Here is my apache2 error log. Had to remove some paths because the forum thought they were links.

I am checking all of the boxes and selecting tar format in the export window.

Is this fixed in ZoneMinder 1.24.4?
