[aether-users] Multiple processes writing to same local repository (in very specific circumstances)
|
Hi,
I am wondering if multiple Aether *processes* (not threads) will corrupt
a shared local repository if the following conditions are met:
- All processes use the *same* remote repository
- All processes only write to the local repository through Aether
- All artifacts in the remote repository are snapshots
- The local repository is managed using
aether.artifactResolver.snapshotNormalization=false.
I observe *.part and .part.lock files being created during the download
and the code in org.eclipse.aether.connector.basic.PartialFile suggests
that multiple processes downloading the same file won't step on each
others toes. Is this true?
And yes, I am aware of the takari-local-repository project [1], but this
also has to handle cases like multiple, different remote repositories,
so it might be overkill. (Besides, it's unlikely that I can get
takari-local-repository and friends OSGified and IP-reviewed in time for
Eclipse Mars.)
Best wishes,
Andreas
