Re: [cross-project-issues-dev] p2 repositories ... we can do better

Well you are just never satisfied are you? :) Just kidding ... it is a good
idea ... but, for the record, that "rather large comment block" was only 5
lines, consisting of only 250 characters. But, granted, that does triple
the size of the minimum 130 character p2.index file. .... and when
requested 500,000 times -- in one day! -- I can see how that'd add up (if
everyone did it).

Besides fixing those files, I added a note to the wiki at
http://wiki.eclipse.org/Equinox/p2/p2_index#Examples

and opened two related bugs:

Bug 373121 - p2 should use request headers accepting compression from
server
Bug 373122 - p2.index files should have no comments


Thanks for helping us improve,

David,

Thanks for sending this out.

I've noticed that on the release repos you've added a rather large
comment block at the top of the file.  This comment block gets
transferred to each client that fetches the file.  And since p2 doesn't
ask for compressed content in its headers, the bytes go out full-sized.

If the only purpose is to maintain some notes, I think a p2.index.readme
file would be better, since it would not be transferred.

Just a thought.

Thanks,

Denis
