4a42604cb6 - Added Ticket basic term type. Note that this only has consequences for 
the Arachne type checking. The net result is that a variable of type
  'Ticket' can always contain any term, even with -m0 or -m1 matching.

cd2ef14e4e - [Syntactical changes only] 
Fixed the indentation of some files.

01124e2104 - Modified a number of things related to the attack analysis tools. 
* removed <term> wrappers
  * added <const> wrappers
  * removed <role><term> construct, now <rolename>R</rolename>
    constructs.
  * added <variables> section.
  * variable substitutions are followed through in runs. Thus, only
    unbound variables occur in the semitrace.
  * added the untested claims back in, so that all events in a
    role/semitrace are now shown. Note that they can be disabled
    again by using the new '-H' switch.

f22ce0dcb9 - Big change in the Arachne algorithm: decryptor sequences now get 
expanded explicitly. This solves a long-standing issue with {k}k
  decryption to yield k. Needs some testing to ensure that it did not
  introduce any new errors.

924abc065d - Added xml output switch (-x, check scyther --help). It's not complete 
yet, to be finished tomorrow.

738a2b5859 - Rewrote complete switch code. Scyther now no longer depends on 
argtable2. Great.

820c2caed8 - Revisited type matching conditions. 
- Introduced tuple unfolding stuff for Arachne. -m2 should work now.

5e695097f2 - Reimplemented the weight functions for goal selection. 
- Added --goal-select function, defaults to 3.

93ab6a29f4 - Omitted some addnew tests, although they ought to work. 2004-12-09 15:45:14 +00:00

b56c01c422 - Added '--max-depth=X' switch (which is equal to the old '-l X -a') 
- Modified semantics of -l with -a : this corresponds more to the
  intuition and introduces the new option to prune proofs based on trace
  length.

3ca180d968 - Despite a full afternoon of debugging, semiRunCreate/Destroy still 
lose 8 blocks. I'm fairly confused.

a38925c9c2 - Added some useful macros to term.h to address subparts (e.g. 
TermOp1(t)). Renamed all uses.

61457b5f3d - Fixed the agentsOfRunPrint output. It was caused by the agent adding 
order.
- Fixed the pruning bug, which was related to this.

487212a9f9 - The TMN protocol was wrongly reporting an error in the protocol. This 
turned out to be caused by an over-protective first-read detection.

02e99761ae - Split roleInstance into two more managable parts. 2004-09-20 12:40:01 +00:00

8b48aade68 - Huge effort to make match type 2 (typeflaw generic) matching work. 
Problem with goals that turn into tuples, will have to be solved.

5c90522c55 - Fixed a bug in the pruning algorithm, where intruder runs were also 
checked for agent lists, which is false.

542044e36f - Added preliminary labellist support to the system. 2004-08-27 11:52:43 +00:00

d58fc5ab43 - Made the label naming unique, by adding tuple info with the protocol 
name. Now, we can simply test multiple protocol names by
  concatenation.
- Removed the pointer equality leaf hypothesis, as it didn't hold
  anymore.

f384042bfe - Switched -r n behaviour for Arachne, effectively turning it into the 
upper bound on runs.

c518e68881 BROKEN 
- Added broken attempt to solve to problem, where a new instance has to
  be bound, but older variables point to role terms, e.g. RV#1->RV.
  What should happen, is that it becomes RV#1->RV#new. I thought of a
  solution, but it is still somewhat broken. Maybe I should ignore any
  mappings of variables such as RV, which might be included.

But why?

a3828a028f - Fixed the very annoying bug! The problem was in roleInstance for 
Arachne. When a subst was carried out by an Rolename->compoundTerm
  substitution, the compound term was not duplicated, and this caused
  problems at roledef destruction.

ff224fee8a - Some cleanup. 
- Added iteration limit, just enough to show the error.

to struct field order.

  not used everywhere yet.

742a65bac1 - Added claim symmetry reduction; this doesn't help much for lower 
number of runs. It is on by default.

7fbd43986f Preparations for Arachne. 
- roleInstanceDestroy is very much needed.
