2009-10-21This big commit addresses two problems:soubiran
1- Management of the name-space in a modular development / sharing of non-logical objects. 2- Performance of atomic module operations (adding a module to the environment, subtyping ...). 1- There are 3 module constructions which derive equalities on fields from a module to another: Let P be a module path and foo a field of P Module M := P. Module M. Include P. ... End M. Declare Module K : S with Module M := P. In this 3 cases we don't want to be bothered by the duplication of names. Of course, M.foo delta reduce to P.foo but many non-logical features of coq do not work modulo conversion (they use eq_constr or constr_pat object). To engender a transparent name-space (ie using P.foo or M.foo is the same thing) we quotient the name-space by the equivalence relation on names induced by the 3 constructions above. To implement this, the types constant and mutual_inductive are now couples of kernel_names. The first projection correspond to the name used by the user and the second projection to the canonical name, for example the internal name of M.foo is (M.foo,P.foo). So: ************************************************************************************* * Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values * ************************************************************************************* Map and Set indexed on names are ordered on user name for the kernel side and on canonical name outside. Thus we have sharing of notation, hints... for free (also for a posteriori declaration of them, ex: a notation on M.foo will be avaible on P.foo). If you want to use this, use the appropriate compare function defined in name.ml or libnames.ml. 2- No more time explosion (i hoppe) when using modules i have re-implemented atomic module operations so that they are all linear in the size of the module. We also have no more unique identifier (internal module names) for modules, it is now based on a section_path like mechanism => we have less substitutions to perform at require, module closing and subtyping but we pre-compute more information hence if we instanciate several functors then we have bigger vo. Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions above, i will work on it soon... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12406 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-02-01Beaoucoup de changements dans la representation interne des modules.soubiran
kernel: -declaration.ml unification des representations pour les modules et modules types. (type struct_expr_body) -mod_typing.ml le typage des modules est separe de l'evaluation des modules -modops.ml nouvelle fonction qui pour toutes expressions de structure calcule sa forme evaluee.(eval_struct) -safe_typing.ml ajout du support du nouvel operateur Include.(add_include). library: -declaremods.ml nouveaux objets Include et Module-alias et gestion de la resolution de noms pour les alias via la nametab. parsing: -g_vernac.ml4: nouvelles regles pour le support des Includes et pour l'application des signatures fonctorielles. extraction: Adaptation a la nouvelle representation des modules et support de l'operateur with. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10497 85f007b7-540e-0410-9357-904b9bb8a0f7

2007-03-27Modification de la vm:notin
- le type val_kind n'embarque plus le constr (pb de cohérence avec le context); - en revanche, lors du calcul d'une valeur, on calcule aussi l'ensemble des variables nommées dont la valeur peut dépendre; - lors du clear_hyps, si la valeur dépend d'une variable effacée, on invalide le calcul.
