SimGrid (3.17) UNRELEASED (release target: September 22 2017)
+ The Drained Leaks release: (almost) no known leaks despite the tests.
+
+ Even very long simulations will preserve your memory: our testsuite
+ stresses SimGrid for over 45mn on fast machines, and there is only
+ one single known leak, of about 4kb.
+
+
S4U
- - Comm.detach(): start and forget about asynchronous emission
+ - Comm.detach(): start and forget about asynchronous emission. A cleanup
+ handler may be given to free resources if the comm cannot be completed.
- this_actor::send(mailbox) is now mailbox->put()
- New: simgrid::s4u::Comm::wait_all()
+ - New: Host.execute() for remote executions.
SURF
- Unused option network/sender-gap is removed.
- Deprecate MSG_task_isend_with_matching(): This unused feature
really complicates our internals. Will be removed in v3.20.
+ Simix
+ - Improved context termination. It is now possible to free resources, even
+ when a process is forcibly killed.
+ - ContextBoost: add support for Boost versions above 1.61.
+
+ XBT
+ - Bring back run-time option --cfg=exception/cutpath to remove exception
+ backtraces.
+
+ Misc
+ - Removed header files obsolete since SimGrid 3.12:
+ msg/datatypes.h, msg/msg.h, simdag/datatypes.h, simdag/simdag.h.
+ - Fix many bugs:
+ - #3: SD_exit should be made optional
+ - #120: Memory leak when the processes are forcefully killed
+ - #159: Threading test regression in Actor refcounting
+ - #170: simgrid::s4u::Comm::wait_any() returns too many comms
+ - #185: simgrid::s4u::Engine::instance()->shutdown() segfaults
+ - #186: Actor::killAll() segfaults if some process is blocked on wait()
+ - #191: VM migration and pstate
+ - #192: Updating the energy consumptions of all hosts crashes with VMs
+ - #195: All actors have PID=0 in the logs
+ - #204: Sometimes segfault with thread contexts and mmap privatization
+ - #222: Actor::kill() doesn't really kill and segfaults
+ - #225: Actor::kill() doesn't really kill when victims are doing a join()
+
