e902aaa260 - Added well-formedness checks. This will only be enabled if a role uses 
the 'knows' keyword.

df1a56c780 - Iteration seems to work nicely, thank you. 2006-07-27 11:55:24 +00:00

2e94dd065e - "--clusters" output is quite advanced, but still dot makes a bit of a 
mess out of it. One of the reasons is that the intruder events
  cannot be used along with the normal ranking, because they no longer
  correspond to real events.

d2058d937b - Revised cost heuristic. Trace length is no longer the real 
optimization.

e1890ddc9f - Improved cost function: now also avoids using initiators when 
possible.

cb440700e3 - Added --unique responder/initiator switches, which are both implied by 
--extravert.

5fe55d35cf - Code refactoring. 2006-03-28 14:45:02 +00:00
ccremers
1ce03104c5 Major: 
- Added rho/sigma/constants fields to the runs, on which the new code is
  based. Over time, .locals should be deprecated in favour of these
  better variants.
- Untyped variant is out of grace for the time being (cf. Athena interm
  problems)
- Improved graph output further.

Minor:
- Added TERMLISTADD and APPEND macros for more concise code.

25244c5b23 - Fixed bug in new tuple expansion code (again, caused by the intricate 
"realX" versus "isX" distinction.)
- Added structures for rho, sigma, constants, but did not activate them
  yet.

5487d3ae90 - From this version onwards, Scyther no longer supports the modelchecker 
method. A big cleanup has been started, but is not finished yet, so
  minor artefacts might still remain. These are to be cleaned up later.

b49d13b6ee - [[[ Broken commit. ]]] 
Stuff seems to be working again, slightly less efficient though (count
  states).

Committing partial new Warshall work because it is getting too big.

164e325659 - New attack attribute. 2005-07-01 13:25:54 +00:00
ccremers
1bdaf7b5d9 - Large rewrite of switch code. Instead of having switch parameters in 
the (monstrously large) system structure, there is now a global
  'switchdata' structure originating in switches.c. This makes it much
  easier to see what's happening.
  * Note: although this code has been tested, there might be some
    hiccups, because doing multiple search&replace actions over all
    files is bound to cause some problems.

1331f5e7a3 - Added a global attack id, starting at one. Currently only shown in 
XML and Dot output. For Dot, it is included in the label. For XML, it
  is an added attribute of the 'attack' tag.

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.

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

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

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.

proof of correctness.

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.

0f470cf6a2 - Rewrote roleInstance to cope with Arachne needs. 
- Introduced some iterators for e.g. term leaves and roledefs. These are
  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.
- fixed bug in maxruns maintenance for incRuns.
- Arachne does not use run knowledge.

4d1362cb1b - Implemented --check=Secret switch, which allows checking of specific 
properties.
- Fixed a bug in the symbol table, where symbols were never inserted
  into the hash table.

specific scenario.

c88c1d4461 - Removed --claims flag again.

dda2907492 - Implemented output method selector, sys->output. 
- Changed disable-report switch into --empty.
- --scenario=-1 now displays a list of scenarios. Use wc -l to count
  them.

472de3b526 - Added switch --choose-first. 
- Added switch --scenario (-s), to enable scenario exploration only.
  Use --scenario=-1 to count the number of possible scenarios.

4f1c9ecb48 - Amazingly, I think I implemented ni-synch partial order reduction. It 
still needs some careful analysis though.

60b02eea0e - Renamed nearly all files. Now, we try to use singular terms. 
Exception: states.h is the plural form.

ace16a896f - Renamed runs.[c|h] to system.[c|h], which makes much more sense. 2004-07-24 15:08:35 +00:00
