- Reverted the patch to ConcreteSimulation, I was trying to make it do what ought to be done in the frontend, and now the frontend does it

- Little patch to ConcreteHistory to make it remove emptied requests after a resource removal. I hope this will not break anything...
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@926 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Actually there is some printing issue to fix, but
the logics works fine.

the user may now add plugin directories,
policy directories, and set the simulation
speed.
- Added some menu voice to the main window.
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@872 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Now CPUPolicy has a callback method for scripting languages, but it is up to derived classes to take
mutexes and set the value when needed (maybe we can improve this?)
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@862 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Added a wizard just for show, but there is no
interesting cpu-scheduling policy to test it with
- Better textual output.

imlpementation, so this version should not be considered definitive.
please give me an other day to check it.

- Added a base class for cpu policy exceptions to make simpler their catching
- Implemented all numeric fields in dialogs with spinboxes, with bounds checking
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@838 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Changed the way syntactically incorrect python policies are handled, we no more exit abruptly
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@829 3ecf2c5c-341e-0410-92b4-d18e462d057c
that the size of the history was the coordinate of the instant
to add.
- Corrected a bug in step forward, which was incorrectly assuming
that all processes started at instant 0.
- Added a wizard to show a bug in step forward, which thinks that
the simulation is terminated while it isn't since some processes
are still future.
- Commented some unused code in step forward (extendThread()).
- Still to extract methods from Extender and provide them to
step forward in a more suitable (static) way.

- Setup makefile for xmlsave plugin. It still can`t be activated. why?
- Added a temporary command SAVE to commandline interface to try serialization

at all. Compiles and runs, but the output is not
correct. Anyway, now it is just a matter of logics :P
- Corrected some minor bugs in step forward.
- Step forward is now rather messy, but still better than
four hours ago.. altough this can be hard to believe.
- Added some wizards that help finding bugs.
- Rewritten dyn process get_state as it was guilty of
premature optimization :)

copy constructor and by the add_resource and remove_resource methods
found in ConcreteHistory.
- Scheduler now adds the requests in the queue when appropriate, and
removes them when exhausted.
- Still to implement the management of the state of requests depending
on their position in the queue
- Still to implement the way threads block depending on the state of
their requests
- step_forward now reuses some bunch of code taken from the prototype

derived widget
- Add History::set_notify_enabled() for usage by the frontend
(for example, when loading from file, you'll want to call
set_notify_enabled(false) before starting)
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@823 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Added exception specifications to the methods of the serializer interface and xml plugin

their elapsed time
- requests are now behaving nicely, since they are raised at the correct
instant, and terminated at the right instant
- the ready queues are still not ready, tough :(, anyway, now there is
really nothing else to do before them.
- stepforward is looking much more uglier (if possible).

when that thread had just been given the cpu.
fixed a bug involving text-simulation displaying the wrong timestamp for
each snaphot. Now the first snapshot printed is correctly tagged "-1".
added (for the sake of lazyness) a method to readyqueue letting anyone
delete the first element on the queue. Not having this would imply
rebuilding the whole queue each time a thread was selected to run.
Small commits avoid complex mergings.

the step went okay or otherwise if the simulation ended
- Fix simulation states in concrete_simulation.cc
- Manage end of input (now CTRL+D exits the program, and
you can redirect a file in input knowing that at EOF
sgpemv2 will terminate)
- Fix a bug in Scheduler that didn't add the newly created
environment to History when the simulation ended, thus leading
both to a memory leak and an inconsistency in representing
the simulation

- Start code for double buffering in custom widgets, using
an off-screen pixmap. Problem: we don't know the height from the
beginning

by Scheduler or by Environment?)
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@793 3ecf2c5c-341e-0410-92b4-d18e462d057c

where it shouldn't

make life easier to Scheduler
- Go on implementing a bit more of Scheduler::step_forward()
- Remove "places" from SubRequest

vector
- Split push_back in constructors on two lines so the compiler warns
us if returned vectors are temporary objects, or do not match the
expected type

- To make sure libraries are not loaded multiple times, only .so files are considered. Beware that this is not portable
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@731 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Fix SWIG interface to correctly manage things
- PythonPolicyManager isn't a singleton anymore. Since I did this in
a bit of a hurry, check the modifications are right
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@725 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Delete the "serialize()" method of concrete_environment, since useless
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@721 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Work on step_forward() a little more
- Add extra check inside dynamic_thread()::decrease_remaining_time()
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@717 3ecf2c5c-341e-0410-92b4-d18e462d057c
from configure. This is mainly there for buggy compilers / binutils.

- Commented a lot of code to make it compile-able. But still it doesn`t link (at least for me...)

if they want to schedule Threads or Processes altogether
- Move setter methods for last_acquisition/last_release from
DynamicSchedulable to DynamicThread
- Rewrite aforesaid methods, along with the respective getter
methods, into Dynamic(Thread|Process)
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@708 3ecf2c5c-341e-0410-92b4-d18e462d057c
rather thant ${prefix}/include/sgpemv2: users will
be able to use directives like "#include <sgpemv2/scheduler.hh>"
in their headers, which reduces name clashes.
- Make _mutex a protected member of Singleton, so that
inheriters can recycle it :-)
- Add exclusive access control for step_forward()
- Add two states (future and exhausted) to Request
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@707 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Add get_request() method to (Dynamic)SubRequest.
- Implement most of ConcreteHistory. It is a fairly complex class,
with some real evilness in it. It should be thouroughly documented
ASAP.
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@699 3ecf2c5c-341e-0410-92b4-d18e462d057c
- TODO Integrate this new plugin management system into the application
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@697 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Fixed all Dynamic and Static entities lacking proper destructors:
Dynamic entities need to delete Dynamic children, Static entities
need only to delete them from the list of their siblings
- Added methods to get Static "core" from Dynamic*.
- Now get_core() is a pure virtual function into DynamicSchedulable.
A quite nice solution(?), really, if I can say that myself... ;-)
- ConcreteHistory is half-implemented. It's the other half that
worries me.
- TODO: finish off ConcreteHistory, and check that things get destroyed
properly (no leaks allowed, use valgrind).
- TODO: rework Simulation
- TODO: Scheduler rewrite
- *A side note*: this code is becoming a mess. I prefer references over
pointers, but someone other prefer pointers over references, and what
happens is that you've to continously pass from one to another when
invoking other methods... this is bad.

- Fix ReadyQueue constructor
- Change DynamicSubRequest to take an int as a parameter
- Implement ConcreteEnvironment::get_request_queue() (my word, it's ugly!)
- Please note that it still doesn't compile right: ConcreteHistory
and Scheduler need to be radically changed
git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@692 3ecf2c5c-341e-0410-92b4-d18e462d057c
- Add interfaces for Process and Thread into the "sgpem.i" SWIG
interface file, change DynamicSchedulable into Schedulable
- Add dynamic_cast for the return value of ReadyQueue::get_item_at()
into the pyloader "sgpem.i" SWIG interface, so that a Schedulable
can be either recognized as a Thread or a Process
- TODO: wrap STL exceptions in SWIG interface
- Please note that code won't compile until the new History and
Scheduler::step_forward() will be in place. This is a known issue.
