Unzip operation hangs

[dragon57]

I am running the latest rc of PA and just discovered a problem.

I have a large, split zip that seems to hang at the 47% point during the unzip operation.

The zip consists of three files, two files 4.7GB in size (the DVD size listed in the gui) and the third file is 418MB in size.

Let me know what other info you require.

Hey dragon,
we’ve tried and cannot recreate the issue given the sizes you provided, let us know what kind of files are in the archive and which options were used when creating the file.

[dragon57]

The files in the archive are VMware image files. The archive was created by selecting the original directory and choosing the split option using the ‘DVD’ size for the split size. Here is a listing from the zip via PA’s print to txt file option:

deflate method with maximum compression?

anything else checkmarked other than “include system and hidden files”?

and, mode selected for spanning? (you can see it in the drop down menu below the span size options.

[dragon57]

Method is Bzip2, compression is normal. The file was split using Winzip (I don’t see a split/span mode type option in Winzip).

[spwolf]

what version of PA are you using exactly?

[dragon57]

11.60.20

[spwolf]

and do you know what version of WinZip? And what settings did you use? So we can try to re-create the archive.

thanks

[dragon57]

The flow is rather strange. The archive was originally created with 7zip using Method=Bzip2, compression=normal. The archive was one large file.

After the archive was created it was transferred across a wan where it was decided it should be split. The user only had Winzip 11.2 (build 8094) and split the file into DVD sized files.

I can unzip the split archive on my local machine using 7zip, Winzip, and Winrar. The only problem is with the latest build of PA.

[spwolf]

hm, i have to find some older WZ because latest versions report an error when splitting large zip created with 7zip.

[dragon57]

Is the new 11.60 build release today supposed to address this? If so, it still hangs. If not, never mind :).

[spwolf]

nope, could not reproduce.

are these vmware image files downloadable somewhere? i have tried creating similar example, but everything worked fine. It might be something that was special to files compressed.

[dragon57]

No, the image files are not distributable. I will see if I can come up with a reproducible scenario and set of accompanying steps.

that would definetly help us solve the issue…. i created several similar files (filename and filesize), compressed it to bzip, normal in 7z and then spanned it in WZ and works fine here. It probably is more specific that simple spanning on bzip does not work.

I then used 7zip to create a zip file using the settings mentioned earlier in this post. Next, I used Winzip to split this zip into DVD sized files. Finally, I used PA to unzip the split zip. PA eventually hung trying to unzip the split files.

Hopefully you can recreate the problem using these steps.

Let me know if you have any questions.

[spwolf]

reproduced!

[dragon57]

Great!

[spwolf]

PA 2010 11.60.25 is here:

check it out and see if it solves your issue.
It seems that split bz2 zip files were not properly supported!

thanks

[dragon57]

Works!

Many, many thanks.

[spwolf]

@dragon57:

Works!

Many, many thanks.

thank you for reproducible reports

Luckily I have ocd when it comes to details :).
