[cross-project-issues-dev] mirror behavior and p2

[Stephan Herrmann <stephan@xxxxxxxxxxxxxxx>]

Hi,

from my latest tests regarding p2.mirrorsURL I observed:

p2's usage of mirrors seems to depend on the directory timestamp.

I.e., ANY change to the base directory of a p2 repository will 
invalidate its mirrors. 

Since the value of p2.mirrorsURL is this base directory, p2 does not
consider any mirrors if the directory has changed.
Such changes would include: editing artifacts.xml to include or 
modify the p2.mirrorsURL (I was just adding &protocol=http), 
re-adding artifacts.xml to artifacts.jar, re-adding metadata to a
repository that was kept invisible by omitting those metadata,
even removing obsolete (backup) files.

Unless I'm interpreting wrong what I observed, for mirroring to 
work tomorrow *everything* must be in place today and not be 
touched in any way. It wasn't obvious to me that this includes 
touching of the *directory*.

best,
Stephan
