Bug 318945 – Better detection of the nwn discs in nwn-data.

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Myckel Habets 2010-05-08 06:03:27 UTC]

While testing for bug 307373 I found out that the NWN HotU XP2 cd is recognized as the Neverwinter Nights Platinum DVD/CD set, when it is mounted in the cd drive and the install is started. This leads to trying to copy the wrong files, error messages about files not found and asking for the second disc that does not exists. 

The ebuild determines the type of cd based on one file that is also present on the HotU XP2 cd. This is incorrect and the ebuild should have a more robust method of detecting the correct disc.

One possible way could be to calculate the md5sum of some files and determine the type of cd based on that.
For the HotU-XP2 cd the md5sums of the files in the cd root are (the readme.txt might be the most useful in this case):

Reproducible: Always

Steps to Reproduce:
1. emerge nwn-data with HotU XP2 cd already mounted.
2.
3.

Actual Results:  
Neverwinter Nights Platinum DVD/CD set found...
Data installed from the HotU XP2 cd.


Expected Results:  
Error about the wrong disc in the drive and ask for the correct drive.

The same issue might surface with the SoU XP1 cd, but I haven't tested this.

Thanks for the idea.

Unfortunately this is almost impossible to do since the file lists were gathered over many years. Whenever NWN was released in a different package we would simply add the necessary code to the ebuild. The information would come from developers (some of the retired), or in bugs here, in emails straight to us, etc... There are a few editions which are only available in some countries and/or in small volumes, so I'm not even sure we can recover them all now.

To implement this would require going back to these people and asking them to provide checksums. It would be a huge effort even if we knew how to contact them all. Also it seems this happened because you inserted the XP2 CD first instead of CD1. So, usually it shouldn't happen if you follow instructions.

I'm going to close this bug RESOLVED WONFIX. Feel free to reopen if you think this isn't right or if you have a patch.

Thanks,
Denis.
