To make this possible the state id has to reach the kernel. Hence definition_entry has an extra field, and many files had to be fixed.

2013-11-02More Proofview.Goal.enter.aspiwack
Proofview.Goal.enter is meant to eventually replace the Goal.sensitive monad. This commit changes the type of Proofview.Goal.enter from taking a four argument function (environment, evar_map, hyps, concl) from a one argument function of abstract type Proofview.Goal.t. It will be both more extensible and more akin to old-style tactics. This commit also changes the type of Proofview.Goal.{concl,hyps,env} from monadic operations to projection from a Proofview.Goal.t. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17000 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-11-02Makes the new Proofview.tactic the basic type of Ltac.aspiwack
On the compilation of Coq, we can see an increase of ~20% compile time on my completely non-scientific tests. Hopefully this can be fixed. There are a lot of low hanging fruits, but this is an iso-functionality commit. With a few exceptions which were not necessary for the compilation of the theories: - The declarative mode is not yet ported - The timeout tactical is currently deactivated because it needs some subtle I/O. The framework is ready to handle it, but I haven't done it yet. - For much the same reason, the ltac debugger is unplugged. It will be more difficult, but will eventually be back. A few comments: I occasionnally used a coercion from [unit Proofview.tactic] to the old [Prooftype.tactic]. It should work smoothely, but loses any backtracking information: the coerced tactics has at most one success. - It is used in autorewrite (it shouldn't be a problem there). Autorewrite's code is fairly old and tricky - It is used in eauto, mostly for "Hint Extern". It may be an issue as time goes as we might want to have various success in a "Hint Extern". But it would require a heavy port of eauto.ml4 - It is used in typeclass eauto, but with a little help from Matthieu, it should be easy to port the whole thing to the new tactic engine, actually simplifying the code. - It is used in fourier. I believe it to be inocuous. - It is used in firstorder and congruence. I think it's ok. Their code is somewhat intricate and I'm not sure they would be easy to actually port. - It is used heavily in Function. And honestly, I have no idea whether it can do harm or not. Updates: (11 June 2013) Pierre-Marie Pédrot contributed the rebase over his new stream based architecture for Ltac matching (r16533), which avoid painfully and expensively working around the exception-throwing control flow of the previous API. (11 October 2013) Rebasing over recent commits (somewhere in r16721-r16730) rendered a major bug in my implementation of Tacticals.New.tclREPEAT_MAIN apparent. It caused Field_theory.v to loop. The bug made rewrite !lemma, rewrite ?lemma and autorewrite incorrect (tclREPEAT_MAIN was essentially tclREPEAT, causing rewrites to be tried in the side-conditions of conditional rewrites as well). The new implementation makes Coq faster, but it is pretty much impossible to tell if it is significant at all. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16967 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-10-05Moving side effects into evar_map. There was no reason to keep anotherppedrot
state out of one we were threading all the way along. This should be safer, as one cannot forego side effects accidentally by manipulating explicitly the [sigma] container. Still, this patch raised the issue of badly used evar maps. There is an ad-hoc workaround (i.e. a hack) in Rewrite to handle the fact it uses evar maps in an unorthodox way. Likewise, that mean we have to revert all contrib patches that added effect threading... There was also a dubious use of side effects in their toplevel handling, that duplicates them, leading to the need of a rather unsafe List.uniquize afterwards. It should be investigaged. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16850 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
2013-08-23Fixing an incompleteness of the ring/field tacticsamahboub
The problem occurs when a customized ring/field structure declared with a so-called "morphism" (see 24.5 in the manual) tactic allowing to reify (numerical) constants efficiently. When declaring a ring/field structure, the user can provide a cast function phi in order to express numerical constants in another type than the carrier of the ring. This is useful for instance when the ring is abstract (like the type R of reals) and one needs to express constants to large to be parsed in unary representation (for instance using a phi : Z -> R). Formerly, the completeness of the tactic required (phi 1) (resp. (phi 0)) to be convertible to 1 (resp. 0), which is not the case when phi is opaque. This was not documented untill recently but I moreover think this is also not desirable since the user can have good reasons to work with such an opaque case phi. Hence this commit: - adds two constructors to PExpr and FExpr for a correct reification - unplugs the optimizations in reification: optimizing reification is much less efficient than using a cast known to the tactic. TODO : It would probably be worth declaring IZR as a cast in the ring/field tactics provided for Reals in the std lib. The completeness of the tactic formerly relied on the fact that git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16730 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-08-22Fixing a significant efficiency leak in the code of the field tactic.amahboub
The field tactic post-processes the data generated during normalization to ensure that vanished denominators do not cancel: essentially, this step removes duplicates from a list of polynomials and uses the clean list to generate the conjunction of associated non-zero conditions. This conjunction is the proof obligation the user has to prove by hand after a successful call to the field tactic. The computation of the proof obligation statement was performed using a fine-tuned reduction strategy, coded in the newring.ml4 file (see the fv-protect tactic). However, not only this strategy information was forgotten by the kernel, but the strategy used at Qed time caused a real explosion (examples normalized in 70s by the tactic have a one hour Qed). No idea why. The fix consists in opacifying the part of the goal irrelevant to computation and call the vm on the duplicate removal step. BTW this step is programmed in a naive way and can probably be made more efficient. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16728 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-22Field_theory : faster and nicer proofs + nice notations.letouzey
This file should compile now twice as fast as earlier. A large part of this speedup comes from swithching to proofs without "auto" (and also improving them quite a lot). Nicer lemma statements thanks to notations and separate scopes (%ring, %coef, %poly). The Field_correct lemma lost some args (sign_theory ...) during the refactoring. After inspection, this looks legitimate, so I've hack the field tactic accordingly. The args were there probably due to some intuition or similar interfering with local vars. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16721 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-08-08Vernac classification streamlined (handles VERNAC EXTEND)gareuselesinge
The warning output by vernacextend when the classifier is missing is the documentation of this commit: Warning: Vernac entry "Foo" misses a classifier. A classifier is a function that returns an expression of type vernac_classification (see Vernacexpr). You can: - Use '... EXTEND Foo CLASSIFIED AS QUERY ...' if the new vernacular command does not alter the system state; - Use '... EXTEND Foo CLASSIFIED AS SIDEFF ...' if the new vernacular command alters the system state but not the parser nor it starts a proof or ends one; - Use '... EXTEND Foo CLASSIFIED BY f ...' to specify a global function f. The function f will be called passing "Foo" as the only argument; - Add a specific classifier in each clause using the syntax: '[...] => [ f ] -> [...]'. Specific classifiers have precedence over global classifiers. Only one classifier is called. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16680 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

2013-06-06Uniformizing generic argument types.ppedrot
Now, instead of having three unrelated types describing a dynamic type at each level (raw, glob, top), we have a "('a, 'b, 'c) genarg_type" whose parameters describe the reified type at each level. This has various advantages: - No more code duplication to handle the three level separately; - Safer code: one is not authorized to mix unrelated types when what was morally expected was a genarg_type. - Each level-specialized representation can be accessed through well-typed projections: rawwit, glbwit and topwit.
