2013-10-18Future: ported to Ephemeron + exception enhancinggareuselesinge
A future always carries a fix_exn with it: a function that enriches an exception with the state in which the error occurs and also a safe state close to it where one could backtrack. A future can be in two states: Ongoing or Finished. The latter state is obtained by Future.join and after that the future can be safely marshalled. An Ongoing future can be marshalled, but its value is lost. This makes it possible to send the environment to a slave process without pre-processing it to drop all unfinished proofs (they are dropped automatically in some sense). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16892 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-10-18Ephemeron: marshaling friendly keysgareuselesinge
Ideally all unmarshallable content in the state should be stocked using Ephemeron keys. In this way the state becomes always marshallable (because the unmarshallable content is magically dropped). The mli contains more detailed doc. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16891 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-10-03STM: add options to disable fallbacks to ease regression testinggareuselesinge
STM falls back to local, lazy, evaluation if the slave dies badly or if there is a marshalling error. Both things should never occur, but is nice to have the system recover if a bug pops up. Nevertheless during regression testing these fallbacks should be disabled not to hide a new bug. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16841 85f007b7-540e-0410-9357-904b9bb8a0f7

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

2013-08-30Stm: 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

2013-08-25Added a more efficient way to recover the domain of a map.ppedrot
The extended signature is defined in CMap, and should be compatible with the old one, except that module arguments have to be explicitely named. The implementation itself is quite unsafe, as it relies on the current implementation of OCaml maps, even though that should not be a problem (it has not changed in ages). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16735 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-22Misc changes around coqtop.ml :letouzey
- Revised Coqtop.parse_args in a cleaner and lighter style - Improved error message in case of argument parse failure: * tell which option is expecting a related argument * in case of unknown options, warn about them all at once * do not hide the previous error messages by filling the screen with usage(). Instead, suggest the use of --help. - Specialized boolean config field Coq_config.arch_is_win32 - Faster Envars.coqlib, which is back to (unit->string), and just access Flags.coqlib. Caveat: it must be initialized once via Envars.set_coqlib - Avoid keeping an opened channel to the "revision" file - Direct load of theories/init/prelude.vo, no detour via Loadpath Beware : ./configure must be runned after this commit git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16726 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-22More complete hashcons : lists (dirpath), arrays (constr)letouzey
Earlier, the elements of constr arrays were hash-consed, but not the array itself. This helps a bit when the same (f a1 ... an) is manipulated a lot : -20% in the size of opaque terms in Integral_domain.vo and Nsatz.vo Similarly it's interesting to hash-cons sub-lists for dirpaths, since in Coq.A.B and Coq.A.C we could share Coq.A. With this patch, the hash-consing of constr seems quasi-optimal: Pierre-Marie's marshal compactor is unable to shrink opaque tables by more than 2%, and this difference seems to be due to untyped compaction (for the compactor Rel 1 = Prop Pos). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16723 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-22Change in vo format : digest aren't Marshalled anymoreletouzey
Since digests are strings (of size 16), we just dump them now in vo files (cf. Digest.output) instead of using Marshal on them : this is cleaner and saves a few bytes. Increased VOMAGIC to clearly identify this change in the format. Please rerun ./configure after this commit. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16722 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-20Universe counters on slaves are in sync with mastergareuselesinge
Simple framework for remote counters. The slaves ask the master for a fresh value. On the master the thread manager answers with a bunch of fresh values (so that further requests can be immediately satisfied). Remote counters are guarded with a mutex on the master, because all slave managers as well as the master thread can access the counter at the same time. I know the name sucks. These counters are remote for the slaves, and local for the master. I'm open to suggestions... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16713 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-08-08Coqide ported to STMgareuselesinge
Main changes for STM: 1) protocol changed to carry edit/state ids 2) colouring reflects the actual status of every span (evaluated or not) 3) button to force the evaluation of the whole buffer 4) cmd_stack and backtracking completely changed to use state numbers instead of counting sentences 5) feedback messages are completely asynchronous, and the whole protocol could be made so with a minor effort, but there is little point in it right now. Left as a future improvement. Missing bit: add sentence-id to responses of interp command. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16677 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-08State Transaction Machinegareuselesinge
The process_transaction function adds a new edge to the Dag without executing the transaction (when possible). The observe id function runs the transactions necessary to reach to the state id. Transaction being on a merged branch are not executed but stored into a future. The finish function calls observe on the tip of the current branch. Imperative modifications to the environment made by some tactics are now explicitly declared by the tactic and modeled as let-in/beta-redexes at the root of the proof term. An example is the abstract tactic. This is the work described in the Coq Workshop 2012 paper. Coq is compile with thread support from now on. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16674 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
