Test Case taDOM2/23-taDOM2-24-CH

taDOM2 Lock Requests of executed Operation appendChild(contextElementNode, childType, childValue) returns Node

The appendChild operation is executed on the context element node CO and appends a new child to the (at least one) already existing child nodes. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new appended child node (the new last child) is returned.

Behavior specified with base operations:

  • readCO
  • modifyCOLCE
  • modifyLCNSE
Read Set = CO , Write Set = COLCE LCNSE
  • LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:-,LCE:EX]
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-]

taDOM2 Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node CH

The appendChild operation is executed on the context element node CO and appends a new child. The context element node CO has still no child nodes before this operation. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child.The new appended child node (the now only child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyCOLCE

Read and write sets for execution on CH:

Read Set = CH , Write Set = CHFCE CHLCE
  • LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:EX,LCE:EX] on CH
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on CH

Operations must be compatible
