[eclipse.org-architecture-council] [Bug 315073] New: Duplication of bits stressing mirror sites

https://bugs.eclipse.org/bugs/show_bug.cgi?id=315073 
Product/Component: Community / Architecture Council

           Summary: Duplication of bits stressing mirror sites
    Classification: Eclipse Foundation
           Product: Community
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Architecture Council
        AssignedTo: eclipse.org-architecture-council@xxxxxxxxxxx
        ReportedBy: denis.roy@xxxxxxxxxxx


Worldwide download mirror sites enable the Eclipse Foundation to efficiently
distribute Eclipse bits with moderate costs.  However, despite my many efforts
at constructing an exclusion list to filter Nightly and temporary builds, many
mirrors are beginning to consider the disk space requirements for an Eclipse
mirror to be excessive, as witnessed on the eclipse-mirrors mailing list:

http://dev.eclipse.org/mhonarc/lists/eclipse-mirrors/msg00569.html


There may be many factors influencing the amount of disk space we occupy on
mirrors:


-> All-in-one ZIPs -- seemingly useless bit duplication

-> .jar and .jar.pack.gz -- bit duplication that saves bandwidth at the expense
of disk space

-> Stable/Release Candidate builds that linger in the mirrored area for weeks
after they are pertinent

-> Lack of naming convention for directories means it's difficult to construct
an effective exclusion list for Nightly builds that covers everyone's nightly
builds

-> Committer indifference towards cleaning up disk space after releases


So I call on the AC to help me prevent a collapse of our network of download
mirrors.
