* | Remove the Sigma (monotonous state) API.Gravatar Maxime Dénès2017-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reminder of (some of) the reasons for removal: - Despite the claim in sigma.mli, it does *not* prevent evar leaks, something like: fun env evd -> let (evd',ev) = new_evar env evd in (evd,ev) will typecheck even with Sigma-like type annotations (with a proof of reflexivity) - The API stayed embryonic. Even typing functions were not ported to Sigma. - Some unsafe combinators (Unsafe.tclEVARS) were replaced with slightly less unsafe ones (e.g. s_enter), but those ones were not marked unsafe at all (despite still being so). - There was no good story for higher order functions manipulating evar maps. Without higher order, one can most of the time get away with reusing the same name for the updated evar map. - Most of the code doing complex things with evar maps was using unsafe casts to sigma. This code should be fixed, but this is an orthogonal issue. Of course, this was showing a nice and elegant use of GADTs, but the cost/benefit ratio in practice did not seem good.

Note the use of a dedicated exception rather than a failwith for Nameops.Name.out. Drawback of the approach: one needs to open Nameops, or to use long prefix Nameops.Name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows a better control on the name to give to an evar and, in particular, to address the issue about naming produced by "epose proof" in one of the comment of Zimmi48 at PR #248 (see file names.v). Incidentally updating output of Show output test (evar numbers shifted).

|/ / / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | evars. This is for consistency with the rest of the language. For instance, "eremember" and "epose" are supposed to refer to terms occurring in the goal, hence not leaving evars, hence in general pointless. Eventually, I guess that "e" should be a modifier (see e.g. the discussion at #3872), or the difference is removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | | [coqlib] Move `Coqlib` to `library/`.Gravatar Emilio Jesus Gallego Arias2017-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We move Coqlib to library in preparation for the late binding of Gallina-level references. Placing `Coqlib` in `library/` is convenient as some components such as pretyping need to depend on it. By moving we lose the ability to locate references by syntactic abbreviations, but IMHO it makes to require ML code to refer to a true constant instead of an abbreviation/notation. Unfortunately this change means that we break the `Coqlib` API (providing a compatibility function is not possible), however we do so for a good reason. The main changes are: - move `Coqlib` to `library/`. - remove reference -> term from `Coqlib`. In particular, clients will have different needs with regards to universes/evar_maps, so we force them to call the (not very safe) `Universes.constr_of_global` explicitly so the users are marked. - move late binding of impossible case from `Termops` to `pretying/Evarconv`. Remove hook. - `Coqlib.find_reference` doesn't support syntactic abbreviations anymore. - remove duplication of `Coqlib` code in `Program`. - remove duplication of `Coqlib` code in `Ltac.Rewrite`. - A special note about bug 5066 and commit 6e87877 . This case illustrates the danger of duplication in the code base; the solution chosen there was to transform the not-found anomaly into an error message, however the general policy was far from clear. The long term solution is indeed make `find_reference` emit `Not_found` and let the client handle the error maybe non-fatally. (so they can test for constants.
* | | | [coqlib] Deprecate redundant Coqlib functions.Gravatar Emilio Jesus Gallego Arias2017-05-27
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We remove redundant functions `coq_constant`, `gen_reference`, and `gen_constant`. This is a first step towards a lazy binding of libraries references. We have also chosen to untangle `constr` from `Coqlib`, as how to instantiate the reference (in particular wrt universes) is a client-side issue. (The client may want to provide an `evar_map` ?) c.f. #186

It seems the few uses of `optsync = false` we legacy and shouldn't have any impact. Moreover, non synchronous options may create particularly tricky situations as for instance, they won't be propagated to workers.

| | | * | | Using type classes in the interpretation of "specialize" and "contradiction".Gravatar Hugo Herbelin2017-05-22
| | |/ / / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We do that by using constr_with_bindings rather than open_constr_with_bindings (+ extra call to typeclasses in "specialize"). If my understanding is right, the only effect would be to succeed more in cases where it was failing (in inh_conv_coerce_to_gen). In particular, "specialize" and "contradiction" already have a WITHHOLES test for rejecting pending holes. Incidentally, this answers enhancement #5153.

We give priority to the detection of used names over other (unification) errors so that an error there is not masked in the backtracking made by descend_in_conjunctions. Of course, the question of what best unification error to give in the presence of backtracking is still open.

Because of it intricacy, I cannot really tell the original motivations of this piece of code, although it looks like it was for there for pretty-printing of errors. Anyway, both because the code was dubious and its effect not observed, it cannot hurt to remove it.
