Backporting addition to suspend accepting new variable server connections and
all communications to variable server clients for the duration of reloading
a checkpoint
refs #168
Back ported validate_address fix from trunk.
Added a flag called validate_address to each variable server thread. When
activated each pointer address will be tested to see if it is in memory
the memory manager is tracking. If it is then everything proceeds normally.
If it does not, then an error return value is returned for the value of this
variable.
refs #193
If a variable resolves to a class/structure type the variable server tries to free the
attributes associated with that variable name. But the attributes usually point to
a fixed place in memory that is not allocated. I removed the free statement. I don't
believe this will lead to a memory leak.
refs #165
Did two things to stop the crash. 1. When following an address path if we hit a NULL
address, stop processing and return the NULL. 2. When trying to resolve addresses in
copy_sim_data, if a NULL address is returned then reset the reference to unresolved and
return a dummy value.
Need to fix MTV to handle dummy value returns.
refs #117
Added a test in the variable server listen restart job to see if the the name of the
machine in the checkpoint file matches the machine that we are running on. We
test all of the network names avaiable on the machine. If the name is not found then
we assume that the checkpoint was taken on another machine and wipe out the machine
name. This will default the machine name back to localhost.
Fixes#24.
Changed all header file once include variables to follow the same naming
convention and not start with any underscores. Also deleted old
incorrect copyright notices. Also removed $Id: tags from all files.
Fixes#14. Fixes#22.
