* [cleanup] Unify all calls to the error function.Gravatar Emilio Jesus Gallego Arias2017-05-27
| | | | | | | | | | | | | This is the continuation of #244, we now deprecate `CErrors.error`, the single entry point in Coq is `user_err`. The rationale is to allow for easier grepping, and to ease a future cleanup of error messages. In particular, we would like to systematically classify all error messages raised by Coq and be sure they are properly documented. We restore the two functions removed in #244 to improve compatibility, but mark them deprecated.

| | | | | | | | | | | | | | | | We use heaps instead of continuously adding elements to an ordered list, which was quadratic in the worst case. As a byproduct, this solves bug #5359, which was due to a stack overflow on big lists.
| * Academic prescriptivism strikes back: down with baroque programming in Nsatz.Gravatar Pierre-Marie Pédrot2017-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several cleanups were performed. 1. Removal of dead code lurking around. 2. Removal of global variables used to pass arguments to functions, as well as unnecessary mutable state here and there. We rely on state-passing and encapsulated mutable state. 3. Removal of crazy reference manipulation and its replacement with proper list handling, as well as cleaning up the source and taking advantage of invariants. This should solve algorithmic limitations of the previous code. 4. Opacification of some structures to have a clearer idea of the code requirements. 5. Cleaning of debug printing functions. We thunk the computation of the debugging data, whose computation can be costly for no reason, and we rely on Feedback-based interaction instead of Printf-debugging.

Therefore, one has to add corresponding open statements a the top of every file depending on a Ltac module. This includes seemingly unrelated files that use EXTEND statements.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the function in_ideal of ideal.ml supposes the list of polynomials does not contain zero and is duplicate free. I force this invariant in the call of in_ideal in nsatz.ml4 the function clean_pol returns the reduced list plus a list of booleans that indicates which polynomials have been deleted the function expand_pol translates back the certificate of the reduced to list to the complete list thanks to the list of booleans. The fix is quadratic with respect to the input list which should be ok for reasonable usage of nsatz. If there is some performance issue we could improve the in_pol function.

* | Compilation via pack for plugins of the stdlibGravatar Pierre Letouzey2016-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For now, the pack name reuse the previous .cma name of the plugin, (extraction_plugin, etc). The earlier .mllib files in plugins are now named .mlpack. They are also handled by bin/ocamllibdep, just as .mllib. We've slightly modified ocamllibdep to help setting the -for-pack options: in *.mlpack.d files, there are some extra variables such as foo/bar_FORPACK := -for-pack Baz when foo/bar.ml is mentioned in baz.mlpack. When a plugin is calling a function from another plugin, the name need to be qualified (Foo_plugin.Bar.baz instead of Bar.baz). Btw, we discard the generated files plugins/*/*_mod.ml, they are obsolete now, replaced by DECLARE PLUGIN. Nota: there's a potential problem in the micromega directory, some .ml files are linked both in micromega_plugin and in csdpcert. And we now compile these files with a -for-pack, even if they are not packed in the case of csdpcert. In practice, csdpcert seems to work well, but we should verify with OCaml experts.

| | | | | | | | | | | | | corresponding Declare ML Module command. This changes essentially two things: 1. ML plugins are forced to use the DECLARE PLUGIN statement before any TACTIC EXTEND statement. The plugin name must be exactly the string passed to the Declare ML Module command. 2. ML tactics are only made available after the Coq module that does the corresponding Declare ML Module is imported. This may break a few things, as it already broke quite some uses of omega in the stdlib.

* Makes the new Proofview.tactic the basic type of Ltac.Gravatar aspiwack2013-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Fixing an incompleteness of the ring/field tacticsGravatar amahboub2013-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* The new ocaml compiler (4.00) has a lot of very cool warnings,Gravatar regisgia2012-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | especially about unused definitions, unused opens and unused rec flags. The following patch uses information gathered using these warnings to clean Coq source tree. In this patch, I focused on warnings whose fix are very unlikely to introduce bugs. (a) "unused rec flags". They cannot change the semantics of the program but only allow the inliner to do a better job. (b) "unused type definitions". I only removed type definitions that were given to functors that do not require them. Some type definitions were used as documentation to obtain better error messages, but were not ascribed to any definition. I superficially mentioned them in one arbitrary chosen definition to remove the warning. This is unaesthetic but I did not find a better way. (c) "unused for loop index". The following idiom of imperative programming is used at several places: "for i = 1 to n do that_side_effect () done". I replaced "i" with "_i" to remove the warning... but, there is a combinator named "Util.repeat" that would only cost us a function call while improving readibility. Should'nt we use it? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15797 85f007b7-540e-0410-9357-904b9bb8a0f7
