4ec5ea4232 Added helper protocol support. 
This is not a full copy from the compromise branch. In particular,
some counts (in arachne.c) are missing, as well as the modified dot output (dotout.c).

a03f06ea41 BUGFIX: Auto-claim naming scheme was context dependent. 
The automatic mechanism to assign labels to claims was dependent on the
context. In practice, a claim could get a different label when analyzed in
isolation compared to when analyzed in parallel with some other protocols. This
caused problems for the multi-protocol analysis.

1814a2d7b3 BUGFIX: Removed obsolete code that was destroying commit/agreement functionality when filtering. 
This is now (and has been for a while) handled by other code.

f883499d07 CHANGE: Changed setup of running & commit. 
Now:

claim(A,Commit,B,data) => claim(B,Running,A,data) and also B is running the right protocol and role.

5f7138c300 BUGFIX: Partial implementation of chosen name attacks could yield false type flaw attacks. 
For the typed model, this was not an issue.

Cas Cremers
66e18deb3f NEW: Added claims: Commit and Running. 
There are two new claims:

  claim(X,Commit,t)  : check for agreement on data
  claim(X,Running,t) : signaling claim

The property checked is that each claim Commit needs to be preceded by a Running
with an identical term t.

Cherry-picked from commit 99a6be00e9d3d219ec73665607e8a3a7d65d04d1

9624c49885 Disable some aggressive error reporting: unclear why this is actually invalid per se 
in the presence of agent name variables (role names) with non-basic typing.

01eb5854cf EFFICIENCY: If a new dependency overlaps with an old one, we don't have to recompute the closure. 2010-11-11 10:37:18 +01:00

6cd8007ab0 EFFICIENCY: New (default) heuristic. 
Given that sk/pk/k are now hardcoded, we can exploit their occurrences with this
new heuristic.

The heuristic can now scan for the lowest term depth at which either sk or k occur.
This will cause the heuristic to favor looking for sk, then sk(x), and only later
other terms. In a small test this was twice as fast. For protocols based on pk only
the performance loss should be negligible.

The old heuristic was 162, now it is 162+512 = 674.

The graph output edge remover was incorrect, and would also
remove applications that were not completely triggered by M_0 alone.

a0a377a84f Added switch to disable verbose exit codes. 
In the near future, the default exit code behavior should be made obsolete anyway,
as the exit codes are not a nice way to report status.
It used to be convenient for shell scripting in early times,
when the parallel tests were run using the forward model
checker, but no modern script should be relying on it.
