* Remove many superfluous 'open' indicated by ocamlc -w +33Gravatar Pierre Letouzey2014-03-05
| | | | | | | | With ocaml 4.01, the 'unused open' warning also checks the mli :-) Beware: some open are reported as useless when compiling with camlp5, but are necessary for compatibility with camlp4. These open are now marked with a comment.
* Lazyconstr -> OpaqueproofGravatar Enrico Tassi2014-02-26
| | | | | Make this module deal only with opaque proofs. Make discharging/substitution invariant more explicit via a third constructor.
* New compilation mode -vi2voGravatar Enrico Tassi2014-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To obtain a.vo one can now: 1) coqtop -quick -compile a 2) coqtop -vi2vo a.vi To make that possible the .vo structure has been complicated. It is now made of 5 segments. | vo | vi | vi2vo | contents --------------+------+-----+-------+------------------------------------ lib | Yes | Yes | Yes | libstack (modules, notations,...) opauqe_univs | No | Yes | Yes | constraints coming from opaque proofs discharge | No | Yes | No | data needed to close sections tasks | No | Yes | No | STM tasks to produce proof terms opaque_proofs | Yes | Yes | Yes | proof terms --------------+------+-----+-------+------------------------------------ This means one can load only the strictly necessay parts. Usually one does not load the tasks segment of a .vi nor the opaque_proof segment of a .vo, unless one is turning a .vi into a .vo, in which case he load all the segments. Optional segments are marshalled as None. But for lib, all segments are Array.t of: | type --------------+--------------------------------------------------------- lib | a list of Libobject.obj (n'importe quoi) opauqe_univs | Univ.consraints Future.computation discharge | what Cooking.cook_constr needs tasks | Stm.tasks (a task is system_state * vernacexpr list) opaque_proofs | Term.constr Future.computation --------------+------+-----+-------+------------------------------------ Invariant: all Future.computation in a vo file (obtained by a vi2vo compilation or not) have been terminated with Future.join (or Future.sink). This means they are values (inside a box). This invariant does not hold for vi files. E.g. opauqe_proofs can be dangling Future.computation (i.e. NotHere exception). The vi2vo compilation step will replace them by true values. Rationale for opaque_univs: in the vi2vo transformation we want to reuse the lib segment. Hence the missing pieces have to be put on the side, not inside. Opaque proof terms are already in a separte segment. Universe constraints are not, hence the new opauqe_univs segment. Such segment, if present in a .vo file, is always loaded, and Declare.open_constant will add to the environment the constraints stored there. For regular constants this is not necessay since the constraints are already in their enclosing module (and also in the constant_body). With vi2vo the constraints coming from the proof are not in the constant_body (hence not in the enclosing module) but there and are added to the environment explicitly by Declare.open_constant. Rationale for discharge: vi2vo produces a proof term in its original context (in the middle of a section). Then it has to discharge the object. This segment contains the data that is needed in order to do so. It is morally the input that Lib.close_section passes to Cooking (via the insane rewinding of libstack, GlobalRecipe, etc chain). Checksums: the checksum of .vi and a .vo obtain from it is the same. This means that if if b.vo has been compiled using a.vi, and then a.vi is compiled into a.vo, Require Import b works (and recursively loads a.vo).
* State Transaction MachineGravatar gareuselesinge2013-08-08
| | | | | | | | | | | | | | | | | | | | | 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

* Proof using: nested sections bugfixGravatar gareuselesinge2012-06-18
| | | | | | | | | | | | | | It used to be the case that the list of declared section variables for a constant was taken into account only when discharging the first enclosing sections, but not any outer section. Example of the bug: Section A. Variable x : bool. Section B. Variable y : nat. Lemma foo : True. Proof using x y. Admitted. End B. End A. Check foo.

* Lazy loading of opaque proofs: fast as -dont-load-proofs without its drawbacksGravatar letouzey2011-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent experiment with -dont-load-proofs in the stdlib showed that this options isn't fully safe: some axioms were generated (Include ? functor application ? This is still to be fully understood). Instead, I've implemented an idea of Yann: only load opaque proofs when we need them. This is almost as fast as -dont-load-proofs (on the stdlib, we're now 15% faster than before instead of 20% faster with -dont-load-proofs), but fully compatible with Coq standard behavior. Technically, the const_body field of Declarations.constant_body now regroup const_body + const_opaque + const_inline in a ternary type. It is now either: - Undef : an axiom or parameter, with an inline info - Def : a transparent definition, with a constr_substituted - OpaqueDef : an opaque definition, with a lazy constr_substitued Accessing the lazy constr of an OpaqueDef might trigger the read on disk of the final section of a .vo, where opaque proofs are located. Some functions (body_of_constant, is_opaque, constant_has_body) emulate the behavior of the old fields. The rest of Coq (including the checker) has been adapted accordingly, either via direct access to the new const_body or via these new functions. Many places look nicer now (ok, subjective notion). There are now three options: -lazy-load-proofs (default), -force-load-proofs (earlier semantics), -dont-load-proofs. Note that -outputstate now implies -force-load-proofs (otherwise the marshaling fails on some delayed lazy). On the way, I fixed what looked like a bug : a module type (T with Definition x := c) was accepted even when x in T was opaque. I also tried to clarify Subtyping.check_constant. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13952 85f007b7-540e-0410-9357-904b9bb8a0f7
* A fine-grain control of inlining at functor application via priority levelsGravatar letouzey2011-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As said in CHANGES: << The inlining done during application of functors can now be controlled more precisely. In addition to the "!F G" syntax preventing any inlining, we can now use a priority level to select parameters to inline : "<30>F G" means "only inline in F the parameters whose levels are <= 30". The level of a parameter can be fixed by "Parameter Inline(30) foo". When levels aren't given, the default value is 100. One can also use the flag "Set Inline Level ..." to set a level. >> Nota : the syntax "Parameter Inline(30) foo" is equivalent to "Set Inline Level 30. Parameter Inline foo.", and "Include <30>F G" is equivalent to "Set Inline Level 30. Include F G." For instance, in ZBinary, eq is @Logic.eq and should rather be inlined, while in BigZ, eq is (fun x y => [x]=[y]) and should rather not be inlined. We could achieve this behavior by setting a level such as 30 to the parameter eq, and then tweaking the current level when applying functors. This idea of levels might be too restrictive, we'll see, but at least the implementation of this change was quite simple. There might be situation where parameters cannot be linearly ordered according to their "inlinablility". For these cases, we would need to mention names to inline or not at a functor application, and this is a bit more tricky (and might be a pain to use if there are many names). No documentation for the moment, since this feature is experimental and might still evolve. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13807 85f007b7-540e-0410-9357-904b9bb8a0f7
* Remove the "Boxed" syntaxes and the const_entry_boxed fieldGravatar letouzey2011-01-28
| | | | | | | | | | | | | | | | According to B. Gregoire, this stuff is obsolete. Fine control on when to launch the VM in conversion problems is now provided by VMcast. We were already almost never boxing definitions anymore in stdlib files. "(Un)Boxed Definition foo" will now trigger a parsing error, same with Fixpoint. The option "(Un)Set Boxed Definitions" aren't there anymore, but tolerated (as no-ops), since unknown options raise a warning instead of an error by default. Some more cleaning could be done in the vm. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13806 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | | | dev/ocamlweb-doc has been erased. I hope no one still use the "new-parse" it generate. In dev/, make html will generate in dev/html/ "clickable version of mlis". (as the caml standard library) make coq.pdf will generate nearly the same awfull stuff that coq.ps was. make {kernel,lib,parsing,..}.{dot,png} will do the dependancy graph of the given directory. ocamldoc comment syntax is here : http://caml.inria.fr/pub/docs/manual-ocaml/manual029.html The possibility to put graphs in pdf/html seems to be lost. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12969 85f007b7-540e-0410-9357-904b9bb8a0f7
* This big commit addresses two problems:Gravatar soubiran2009-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
