 Posted: Sun Aug 15, 2004 9:18 am Post subject: MD5 sum fails on cedega / point2play |
 |
|
What is with these files? I downloaded point2play-small-1.3.1.tgz & cedega_4.0.1-1.i386.tgz and waited for ebuild to come out (I'm not in a big hurry).
Today I saw the new ebuilds so I thought it is time to update these packages. I had a big surprise! The MD5 sums in ebuilds are:
| Code: |
cedega_4.0.1-1.i386.tgz - 30b245977dfa50e7d1adadd9ad4822d2
point2play-small-1.3.1.tgz - 010f033c1a80165959939e9d2f1dd5f5
|
which is different of what I've downloaded a few days ago:
| Code: |
cedega_4.0.1-1.i386.tgz - 7b570bb1e9c834158d6fc29c9e0e3563
point2play-small-1.3.1.tgz - ec618b7591fa175a205652fed9cf58bf
|
Well, I thought I've downloaded screwed files, so I've redownloaded the files. The surprise is that still MD5 sums are different!!!
The really big surprise is that the sum keeps changing on every downloaded archive!!! What the hell?!? |

It seems to contain some sort of ID that is changed at every download:
| Code: |

I also got that problem - that file changed everytime I downloaded it.
I managed to emerge point2play, when I changed MD5 sum in
/usr/portage/app-emulation/point2play/files/digest-point2play-1.3.1
to the one that my downloaded point2play-small-1.3.1.tgz had. |

I had the same problem last night.
ebuild /usr/portage/app-emulation/point2play/point2play-1.3.1.ebuild digest
It's interesting that Transgaming is distributing each download with a unique ID number now, isn't it? Linked to a database with our user name and IP address no doubt. |

Unless we could get ebuilids to support installing without a hash.  |

As if we couldn't re-tar cedega without this stupid ID...
Even if they track the username & IP of one who published cedega, legally they can do nothing about it! |

There is a suggestion there that simply repackaging the tgz wipes the tag. If so, that's gotta be the most pissweak copy protection I've ever seen.
I'd say an ebuild would still work, but people would have to do the repackaging of the tgz to get the right md5sum.
You could also just make your own md5sum, put it in the digest, then stick that in your overlay directory. |

| What about just making the ebuild with an RPM-package, and then let the ebuild convert it til tgz and install it from there? |
