dispatch yields NullPointerException and fails
Reported by Charles Scott | April 9th, 2012 @ 02:17 PM | in Rundeck 1.4.3 (closed)
- Issue Type: Bug
- Rundeck version: 1.4.1
Issue:
java.lang.NullPointerException occurs after executing dispatch that resolves to many hosts either by a tag list or specific list of names. In my debugging, it appears to happen when the resolved set of nodes is 48 or more:

The following commands have triggered the error:
dispatch -C 5 -I tags='qa[0-9]+,int[0-9]+,rgs[0-9]+' -L -- hostname
dispatch -C 5 -I tags='qa1,int1,rgs1,qa2,int2,rgs2,qa3,int3,rgs3,qa4,int4,rgs4,qa5,int5,rgs5,qa6,int6,rgs6,qa7,int7,rgs7,qa8,int8,rgs8,qa9,int9,rgs9' -L -- hostname
Reproduce: (Enter steps to reproduce bug here.)
When using the -I name= parameter,
and set the list to 48 names or longer, we get the NPE
47 works.
Example:
this fails:
dispatch -C 5 -I name='pbintrk1v,pbqark1v,pbqark2v,pbqark3v,pbqark4v,pbqark5v,pbqark6v,pbqark7v,pbqark8v,pbrgsrk1v,pkintrk1v,pkqark1v,pkqark2v,pkqark3v,pkqark4v,pkqark5v,pkqark6v,pkqark7v,pkqark8v,pkrgsrk1v,ptintrk1v,ptqark1v,ptqark2v,ptqark3v,ptqark4v,ptqark5v,ptqark6v,ptqark7v,ptqark8v,ptrgsrk1v,weintrk1v,weqark1v,weqark2v,weqark3v,weqark4v,weqark5v,weqark6v,weqark7v,weqark8v,wergsrk1v,wsintrk1v,wsqark1v,wsqark2v,wsqark3v,wsqark4v,wsqark5v,wsqark6v,pbdevrk1v' -L -- hostname
this works (with one fewer node name)
dispatch -C 5 -I name='pbintrk1v,pbqark1v,pbqark2v,pbqark3v,pbqark4v,pbqark5v,pbqark6v,pbqark7v,pbqark8v,pbrgsrk1v,pkintrk1v,pkqark1v,pkqark2v,pkqark3v,pkqark4v,pkqark5v,pkqark6v,pkqark7v,pkqark8v,pkrgsrk1v,ptintrk1v,ptqark1v,ptqark2v,ptqark3v,ptqark4v,ptqark5v,ptqark6v,ptqark7v,ptqark8v,ptrgsrk1v,weintrk1v,weqark1v,weqark2v,weqark3v,weqark4v,weqark5v,weqark6v,weqark7v,weqark8v,wergsrk1v,wsintrk1v,wsqark1v,wsqark2v,wsqark3v,wsqark4v,wsqark5v,wsqark6v' -L -- hostname

I see that if the content is too large, the API call receives a HTTP 413 result, as it is using GET instead of POST.
the API client code was throwing NPE in the case that there is not Content-Type in the result.
the fix will be to prevent NPE in that case, and to change the API call to use POST.
