* More work on error handlingGravatar letouzey2011-05-17
| | | | | | | | | | | | | | Anomalies are now meant to be the exceptions that are *not* catched and handled by the new Errors.handle_stack. Three variants of [Errors.print] allow to customize how anomalies are treated. In particular, [Errors.print_no_anomaly] is used for the Fail command, instead of a classification function Cerrors.is_user_error which wasn't customizable. No more AnomalyOnError, its only occurrence is now a regular anomaly git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14133 85f007b7-540e-0410-9357-904b9bb8a0f7

* Repair the "Fail" command after recent changes in exception handlingGravatar letouzey2011-05-16
| | | | | | | | | | | | For that, I introduce a explicit classification function is_user_error : exn -> bool, instead of the previous hack of explain_exn_default_aux (fun () -> raise e). By the way, clean a bit explain_exn_default_aux : many cases are just printed fine by default's Printexn.to_string (for example Not_found). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14129 85f007b7-540e-0410-9357-904b9bb8a0f7

* Print Module (Type) M now tries to print more detailsGravatar letouzey2011-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "Print Module M" prints now by default both a signature (fields with their types) and a body (fields with their types and transparent bodies). "Print Module Type M" could be used both when M is a module or a module Type, it will only display th signature of M. The earlier minimalist behavior (printing only the field names) could be reactivated by option "Set Short Module Printing". For the moment, the content of internal sub-modules and sub-modtypes are not displayed. Note: this commit is an experiment, many sitations are still unsupported. When such situations are encountered, Print Module will fall back on the earlier minimalist behavior. This might occur in particular in presence of "with" annotations, or in the conjonction of a non-global module (i.e. functor or module type) and internal sub-modules. Side effects of this commit: - a better compare function for global_reference, with no allocations at each comparison - Nametab.the_globrevtab is now searched according to user part only of a kernel_name - The printing of an inductive block is now in Printer, and rely less on the Nametab. Instead, we use identifiers in mind_typename and mind_consnames. Note that Print M.indu will not display anymore the pseudo-code "Inductive M.indu ..." but rather "Inductive indu..." git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14117 85f007b7-540e-0410-9357-904b9bb8a0f7

* Coqide: better handling of stdout/stderr in win32Gravatar letouzey2011-04-21
| | | | | | | | | | | | | | | | | | Now that coqide is a console-free win32 app, writing to nonexistent stdout/stderr lead to Sys_error. To avoid that: - We reroute coqide's stdout/stderr to either a pipe that will stay unread (by default), or to a temp log file (in debug mode). - When doing create_process, avoid referring to Unix.stderr: anything printed by coqtop to its stderr will be merged in the regular channel. - On the coqtop side, remove the awkward fix consisting in a \r printed on stderr apparently to fix coqide.byte. This fix is probably obsolete since the separation of coqide and coqtop as distinct processes. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14047 85f007b7-540e-0410-9357-904b9bb8a0f7

* 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

Note that currently a vm_compute won't be stopped by a "Stop", but only by a "Goto Start". This can be quite confusing. How to properly document that "Goto Start" has the side effect of being a kill ? Maybe we could check someday if the Ctrl-C has been successful, and kill -9 if not ? Or maybe make coqide aware of a flag "we_are_vm_computing" and then kill -9 instead of Ctrl-C in this case ?

* An automatic substitution of scope at functor applicationGravatar letouzey2011-02-11
| | | | | | | | | | | | | | | | | | | For Argument Scope, we now record types (more precisely classes cl_typ) in addition to scope list. After substitution (e.g. at functor application), the new types are used to search for corresponding concrete scopes. Currently, this automatic scope substitution of argument scope takes precedence (if successful) over scope declared in the functor (even by the user). On the opposite, the manual scope substitution (cf last commit introducing annotation [scope foo to bar]) is done _after_ the automatic scope substitution. TODO: if this behavior is satisfactory, document it ...
