Re: [cross-project-issues-dev] Testing p2.mirrorsURL

Hi David,

yeah, if Denis confirms that this was indeed the case for my mirror problems, I will update the wiki pages with a section on that, explaining also how to convert the repo (the trick is to create a fake artifacts.xml which provides a publishPackFilesAsSiblings property and use this as format in the p2.mirror task)...

Cheers
Alexander

I find this "interesting" for a couple of reasons.

It sounds like we do not mirror .blobstore directories? Denis, can you confirm rsync rules? It would kind of make sense not to by default, since "dot directory" ... but, seems ".blobstore" should be an exception.

I'm not sure of all the ins and outs (a p2 expert could speak to this) but sometimes "publishing a repo" puts all the jar.pack.gz files in .blobstore directory instead of as peers to their corresponding jars.

Second, if we "must not" use .blobstore for eclipse foundation mirrored repos, I am not sure we have ever documented that or provided any "how to". And, if I recall, the "how to" isn't obvious ... not too hard once you know the trick ... but, I do not recall the trick right off (I believe it has to do with "copying properties from existing repo" that does not use .blobstore, but I don't recall how to "get" that original repo?).

Sounds like you solved this recently, Alexander, ... perhaps you could add a note to
http://wiki.eclipse.org/Equinox/p2/p2.mirrorsURL
if/when Denis confirms "can not" (or, "should not", or "must not") mirror .blobstore directories?

[And, I should apologize in advance if this is actually documented/discussed somewhere already ... sometimes I forget what I don't know :) ]

Thank you both!

Alexander,

Thanks for testing that.

I hope other projects are also testing their repos for mirror
functionality...  I will accept criticism that download.eclipse.org is
slow due to our bandwidth limitations, but if mirrors are not being
used, that makes matters much worse.

Thanks,

Denis

Having converted the update-site to a form, where pack.gz files are located next to the related bundles, I could observe a different output this morning (after there are now a couple of mirrors that have updated themselves to the changes).
