Jason Howk created JENKINS-13865:
------------------------------------
Summary: Jenkins /queue/api does not produce properly formatted
JSON when a build in queue where the destination node/s are busy.
Key: JENKINS-13865
URL: https://issues.jenkins-ci.org/browse/JENKINS-13865
Project: Jenkins
Issue Type: Bug
Components: core
Affects Versions: current
Environment: Linux
Reporter: Jason Howk
Jenkins /queue/api does not produce properly formatted JSON when build in queue
where a node/s are fully busy. The json produced is un-parsable. This can be
visible on the builds.apache.org server.
Example:
"why":"Waiting for next available executor on
[8mha:AAAAkB+LCAAAAAAAAABb85aBtbiIQSajNKU4P08vOT+vOD8nVc+jsiC1KCczL9svvyT1dMUiOWdZ/mImBiZPBrac1Lz0kgwfBubSopwSBiGfrMSyRP2cxLx0/eCSosy8dOuKIgYpNOOcITTIMAYIYGRiYKgoADLYShgE9JPzcwtKS1KL9HNKk1PzUgENqikilQAAAA==[0mlucene"
Appears that the "why" property of the queued build isn't being formatted
properly. Actually it's being gzipped...
Looking at the source, the hudson.model.queue.CauseOfBlockage class appears to
be the culprit. To wit:
public String getShortDescription() {
return
Messages.Queue_WaitingForNextAvailableExecutorOn(HyperlinkNote.encodeTo("/computer/"+
node.getNodeName(), node.getNodeName()));
}
The nodename is attempting to be encoded with HyperlinkNote:
public static String encodeTo(String url, String text) {
try {
return new HyperlinkNote(url,text.length()).encode()+text;
} catch (IOException e) {
// impossible, but don't make this a fatal problem
LOGGER.log(Level.WARNING, "Failed to serialize
"+HyperlinkNote.class,e);
return text;
}
}
Which calls the supers encode() method:
public String encode() throws IOException {
return encodeToBytes().toString();
}
And finally encodeToBytes():
private ByteArrayOutputStream encodeToBytes() throws IOException {
ByteArrayOutputStream buf = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(new
GZIPOutputStream(buf));
oos.writeObject(this);
oos.close();
ByteArrayOutputStream buf2 = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(new
Base64OutputStream(buf2,true,-1,null));
buf2.write(PREAMBLE);
dos.writeInt(buf.size());
buf.writeTo(dos);
dos.close();
buf2.write(POSTAMBLE);
return buf2;
}
Full output:
