(Its index.jelly does assume getDisplayName is available.)

no need to call toString() on the string
add comments

return a string literal vs a new string object
switching to implicit else

From what I was told by Emanuele today in the office hours, this came up
during the Copenhagen hackathon.

Prefer the postMessage version to retrieve the metadata so that we can leave the existing JSON format as-is for backward compatibility with pre-1.424 Jenkins.

Based on the following exception we observed:

Aug 31, 2012 1:41:05 PM hudson.model.Executor run

Users are now able to update node offline messages without
bringing the node back online and offline.

create a Interface that Actions can implement to indicat that they
should be passed from
the matrix parent to the indiviual configurations.
This means that the SVN Parameters can be passed to them.
Partial fix for [JENKINS-14619] also needs changes in SVN SCM plugin to
fix completely.

as get(String idOrFullName) suggest

so that getAll() don't invoke CanonicalIdResolvers for known IDs

Reduce duplicate entries for the same plugin and version when multiple update centers are publishing similar data

Based on the following IRC conversations:

 (04:02:29 PM) cliffano: my build slave is offline, "Disk space is too low. Only 0.331GB left on" , but the box has 5.5Gb free.. i've tried disabling the disk space checking, restarted both master and slave, that error message is still there
 (04:03:03 PM) rtyler: I've seen that a couple times, I think I just disconnected and reconnected the slave
 (04:03:47 PM) cliffano: no dice for me.. reconnected several times.. even tried deleting more stuffs to free up more space, still exactly the same error message
 (04:04:04 PM) rtyler: you could try reinstalling windows
 (04:04:06 PM) ***rtyler ducks
 (04:04:22 PM) cliffano: lol yea
 (04:04:49 PM) kohsuke: cliffano: you can force the recomputation of those metrics
 (04:04:56 PM) kohsuke: otherwise it's only once an hour
 (04:05:17 PM) rtyler: wait, you can force it?
 (04:05:37 PM) kohsuke: http://ci.jenkins-ci.org/computer/ "refresh status"
 (04:06:26 PM) rtyler: ah
 (04:07:25 PM) cliffano: kohsuke: thanks, that worked..
 (04:07:43 PM) kohsuke: although I expect that if you've been reconnecting that should be sufficient
 (04:08:08 PM) kohsuke: And I probably should also do that automatically when you reconfigure the column, threashold, etc
 (04:10:39 PM) cliffano: kohsuke: reconnecting didn't help somehow... i tried disconnecting from the UI, tried killing the process on the slave machine, restarted etc
 (04:10:56 PM) kohsuke: it's probably caching the value
 (04:12:16 PM) cliffano: kohsuke: does it cache in the filesystem? i restarted both master and slaves
 (04:13:09 PM) kohsuke: it's stored in Computer
 (04:13:11 PM) kohsuke: so I guess that explains
 (04:13:34 PM) kohsuke: let me clear this when a slave connects
 (04:16:23 PM) cliffano: kohsuke: thanks :)
