2018-11-06[checker] Refactor by sharing code with the kernelMaxime Dénès
For historical reasons, the checker was duplicating a lot of code of the kernel. The main differences I found were bug fixes that had not been backported. With this patch, the checker uses the kernel as a library to serve the same purpose as before: validation of a `.vo` file, re-typechecking all definitions a posteriori. We also rename some files from the checker so that they don't clash with kernel files.

2017-05-27[cleanup] Unify all calls to the error function.Emilio Jesus Gallego Arias
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.

2016-06-18Fixing the checker.Pierre-Marie Pédrot
I had to remove code handling the -type-in-type option introduced by commit 9c732a5. We should fix it at some point, but I am not sure that using the checker with a system known to be blatantly inconsistent makes much sense anyway.
2016-05-31Feedback cleanupEmilio Jesus Gallego Arias
This patch splits pretty printing representation from IO operations. - `Pp` is kept in charge of the abstract pretty printing representation. - The `Feedback` module provides interface for doing printing IO. The patch continues work initiated for 8.5 and has the following effects: - The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`, `pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`, `msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be used instead. - Feedback provides different backends to handle output, currently, `stdout`, `emacs` and CoqIDE backends are provided. - Clients cannot specify flush policy anymore, thus `pp_flush` et al are gone. - `Feedback.feedback` takes an `edit_or_state_id` instead of the old mix. Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.

2014-03-11vi2vo: universes handling finally fixedEnrico Tassi
Universes that are computed in the vi2vo step are not part of the outermost module stocked in the vo file. They are part of the Library.seg_univ segment and are hence added to the safe env when the vo file is loaded. The seg_univ has been augmented. It is now: - an array of universe constraints, one for each constant whose opaque body was computed in the vi2vo phase. This is useful only to print the constants (and its associated constraints). - a union of all the constraints that come from proofs generated in the vi2vo phase. This is morally the missing bits in the toplevel module body stocked in the vo file, and is there to ease the loading of a .vo file (obtained from a .vi file). - a boolean, false if the file is incomplete (.vi) and true if it is complete (.vo obtained via vi2vo).

2013-04-02Revised infrastructure for lazy loading of opaque proofsletouzey
Get rid of the LightenLibrary hack : no more last-minute collect of opaque terms and Obj.magic tricks. Instead, we make coqc accumulate the opaque terms as soon as constant_bodies are created outside sections. In these cases, the opaque terms are placed in a special table, and some (DirPath.t * int) are used as indexes in constant_body. In an interactive session, the local opaque terms stay directly stored in the constant_body. The structure of .vo file stays similar : magic number, regular library structure, digest of the first part, array of opaque terms. In addition, we now have a final checksum for checking the integrity of the whole .vo file. The other difference is that lazy_constr aren't changed into int indexes in .vo files, but are now coded as (substitution list * DirPath.t * int). In particular this approach allows to refer to opaque terms from another library. This (and accumulating substitutions in lazy_constr) seems to greatly help decreasing the size of opaque tables : -20% of vo size on the standard library :-). The compilation times are slightly better, but that can be statistic noise. The -force-load-proofs isn't active anymore : it behaves now just like -lazy-load-proofs. The -dont-load-proofs mode has slightly changed : opaque terms aren't seen as axioms anymore, but accessing their bodies will raise an error. Btw, API change : Declareops.body_of_constant now produces directly a constr option instead of a constr_substituted option git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16382 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-04-03Lazy loading of opaque proofs: fast as -dont-load-proofs without its drawbacksletouzey
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

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
