A bug in MassDownloader RAR preview

Author Message

It's been a while since I wrote here, but I hope you still remember me: I'm the person who provided the idea of implemented RAR preview in MassDownloader and tested it when it's been implemented. You even credited me with a free Mass Downloader regcode.

Anyway, I've found another bug in MassDownloader RAR preview: large file sizes are displayed incorrectly. For instance 4539875328 bytes is displayed as 244908033 bytes. Can you fix this?

I tried writing to Alexander Baranov who had been MassDownloader developer in the past, but got receipt which said the message couldn't be delievered because his mailbox is full. Probably he's no longer active in MassDownloader development.

Not only it still displays size of large files incorrectly, but this "fixed" version has comletely lost the ability of previewing files on FTP :-[

Naaloh,

I worked well in our yesterday tests. I just checked - it works now, both in FTP Passive mode and without it.
The nember of build I am talking about is 3.8.10.844, please confirm.
Please send me links you have problems with. It works perfect for ftp://ftp.marsat.ru/MOPS/MOPS_DVD_Image.rar.

Thanks,
Alexander

I confirm that it's 3.8.10.844. After I deleted the "HKEY_CURRENT_USER\Software\MetaProducts\Mass Downloader" registry key to reset all preferences it managed to preview ftp://ftp.marsat.ru/MOPS/MOPS_DVD_Image.rar, displaying the size correctly. However the total size of files selected for download which is shown at the bottom of the preview window is still displayed incorrectly (in case of that archive it says "1 file(s) selected for download, total size is -1554826609").

Also when I tried to preview an archive containing a file over 4GB over HTTP, it still displayed its size incorrectly (244908033 instead of 4539875328). I can't give you a direct link because the file is located on a filesharing service. You can get it yourself if you go to http://www.megaupload.com/?d=JSY1ZHBE

Alexander Bednyakov, is anything going to be done about this?

Naaloh,

Please excuse us for the delay - it was the vacation period.
Could you please test the build from: http://www.metaproducts.com/files/Massdown.zip ?
Please write us about the result. Thank you.

Best regards,

Seems to work correctly with the sample archive now... I do hope that the new limit of correctly displayed size is not 8 GB, but a bit more. After all RAR supports files up to 9,223,372,036,854,775,807 bytes (8,589,934,591 GB), so I don't see a point of being exactly one step ahead of the largest encountered file :-))
