[p2-dev] P2 Mirror Application fails to mirror Eclipse repo
|
Hi
All,
I am in the
process if testing 2 mirror sites created using the P2 MirrorApplication. The
external sites are:
I am testing the
mirrors by attempting to update a 3.4.0 installation from them. I have
encountered various errors whilst testing (including Bug 251716). I am now wondering if the
MirrorApplication has created faithful mirrors. So I downloaded the content.jar
and artifacts.jar manually from the 2 external sites and compared the xml in all
cases with that generated by the P2 MirrorApplication. Note: My mirror script removes the references section
from the generated content.xml.
Eclipse
repo:
------------
artifacts.xml
- downloaded:
663,552 bytes; artifacts size='1674'
- generated1: 831,488 bytes; artifacts
size='1829'
- generated2: 741,376 bytes;
artifacts size='1671'
content.xml
- downloaded: 3,956,736
bytes; units size='1373'
- generated1: 4,001,792
bytes; units size='1373'
- generated2: 4,001,792 bytes; units
size='1373'
Ganymede
repo:
----------------
artifacts.xml
- downloaded:
671,744 bytes; artifacts size='1943'
- generated: 684,032 bytes; artifacts
size='1943'
content.xml
- downloaded: 13,361,152
bytes; units size='2436'
- generated:
13,438,976 bytes; units size='2436'
Differences between the generated and downloaded
ganymede repo metadata are probably non-significant. However, the differences for the Eclipse repo are kind of
worrying. In addition, the results of mirroring this repository are
inconsistent. Compare generated1 and generated2 for artifacts.xml
(created by 2 separate runs of the MirrorApplication) neither of which are
the same as the original.
Cheers,
Miles
