2013-08-30recdef: restore old semantics (pre STM)gareuselesinge
The Stm commit switched from an home made handling of failures to a with_state_protection. This was wrong, since in case of success the global state has to be left altered. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16746 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-30safe Conv_oracle state for type checkinggareuselesinge
safe_typing is not purely functional, hence we cannot chain it as if it was a pure computation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16744 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-30Stm: if slave process dies badly go back to local lazy evaluationgareuselesinge
Processing the proof in a slave process may fail for an implementation error, e.g. the state could not be marshalled, or an anomaly is raised by the slave. In this case we fall back to local, lazy, evaluation in the master process. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16743 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-08-08Future library to represent pure computationsgareuselesinge
Since the whole system is imperative, futures are run protecting the global state, and the final state is also saved to let the user freely chain futures. Futures can represent local (lazy) computations or remote ones (delegated). Delegating a future lets a third party assign its value at some poit in the future; in the meanwhile accessing the future value raises an exception. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16669 85f007b7-540e-0410-9357-904b9bb8a0f7
