Hi,

After syncin' a few moment ago I get a bad digest for pyxml 0.8.4, has anyone
noticed this as well?

Calculating world dependencies |!!! Digest verification failed:
!!! /usr/portage/dev-python/pyxml/pyxml-0.8.4.ebuild
!!! Reason: Filesize does not match recorded size
!!! Got: 1120
!!! Expected: 1126

I know it's possible to recalculate these hashes and stuff, but could anyone
tell me how it works?

Regards,

Wimmy

Yes, the same package gave me a bad file size too, this morning.

These occur regularly, if you emerge sync frequently.

Firstly, you have actually inherited the corruption from rsync server. If you
emerge sync again it will likely go away.

Each package has a list of MD5, SHA1, SHA256 and whatever hash values for each
file in the package: the ebuild, any tarballs, etc. Each file also has a
specified size, so that the checksum(s) and the file size must all match with the
downloaded resource files.

The above message is telling you the ebuild is 6 bytes too large for the file
size, or the file size is 6 bytes too small for the ebuild file. If you examine
the ebuild file, with less or the like, and it looks valid, you can have the file
size and has values recalculated using:

ebuild /usr/portage/dev-python/pyxml-0.8.4.ebuild digest

[You will need to be root to do this.] If a tarball has a wrong hash value or
size, use tar -tjf <tarball> to test its validity before you have the hashes
recalculated for the ebuild.

First of all: what the hell is wrong with the NG's over here? My and other
messages in this thread are being duplicated like 4 times... :-s

But anyway, I know the principle of hashes and checksums, just not how to
generate them again with ebuild. Tis the first time however I've synced in an
error from the portage tree, someone needs some spankin'! ;-)

Thanks anyway,

Wimmy

Well, way to go! :-)

From what I've just learned this seems to be the culprit:
http://www.ftngate.net/fidonet/z1/r1...3C%3CPRISM_BBS

Or am I wrong?
