* Dir_path --> DirPathGravatar letouzey2013-02-19
| | | | | | | | Ok, this is merely a matter of taste, but up to now the usage in Coq is rather to use capital letters instead of _ in the names of inner modules. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16221 85f007b7-540e-0410-9357-904b9bb8a0f7

* Mod_subst: an extra assertGravatar letouzey2013-02-19
| | | | | | | | | | | It seems that the Equiv delta_hint in a resolver have a particular shape: a kn can apparently only be shifted to another kn with same label this way. We validate this fact via an assert, since this isn't obvious (due to recursive calls in Mod_subst and Modops), and since this implies the important fact that user and canonical parts of kernel pairs have necessarily the same label (and section dirpath). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16219 85f007b7-540e-0410-9357-904b9bb8a0f7
* Classops : avoid some use of GmapGravatar letouzey2013-02-19
| | | | | | | | | | | | Gmap uses Pervasives.compare which may interact badly with structures like pairs of kernel names For the moment, we consider elements in classes and coercions only according to their user kernel name: this provides maximal compatibility. But it could be interesting to try using comparision according to canonical kernel names... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16218 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | - a module KernelPair for improving sharing between constant and mind - shorter representation than a pair when possible - exports comparisions on constant and mind and ... - a kn_equal function instead of Int.equal (kn_ord ...) 0 git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16217 85f007b7-540e-0410-9357-904b9bb8a0f7
* Mod_subst: improve sharing during kn substitutionsGravatar letouzey2013-02-18
| | | | | | | | | When user and canonical parts are physically equal, let's avoid computing both their substitutions : this is a waste of time and also potentially of memory sharing. For instance two identical sub-calls to subst_mp0 may produce answers that are = but not ==. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16216 85f007b7-540e-0410-9357-904b9bb8a0f7

Basically, it adds an additional cell to exceptions arguments, in which you can put whatever you want. By typing invariants, you may not reach this cell by normal means, so it should be safe. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16212 85f007b7-540e-0410-9357-904b9bb8a0f7

* Displaying environment and unfolding aliases in "cannot_unify"Gravatar herbelin2013-02-17
| | | | | | | | | | | | error. Maybe displaying environment is making output overly verbose, but this can also be considered an IDE issue, which would e.g. provide a button to hide/display environment of the error message... Also added some "make_all_name_different" which should probably prevent some anomalies "index to an anonymous variable" at error reporting time. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16208 85f007b7-540e-0410-9357-904b9bb8a0f7
* A more informative message when the elimination predicate forGravatar herbelin2013-02-17
| | | | | | | | | | | | destruct, rewrite, etc. is not well-typed. Also added support for a more informative message when the elimination predicate is not well-formed while using the smart "second-order" unification algorithm. However the "abstract_list_all" algorithm seems to remain more informative though, so we still use this algorithm for reporting about ill-typed predicates. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16207 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | interleaving of ltac and ml code is not visible (this particularly applies to ltac notation ring, which calls ml-level ring_lookup and Ring again at the ltac level, resulting in non-localisation of "ring" errors). Added also missing LtacLocated checks in Class_instance and Proofview. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16204 85f007b7-540e-0410-9357-904b9bb8a0f7
* Fix extraction of inductive types that Coq auto-detects to be in PropGravatar letouzey2013-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | Typical example : Inductive t := T : t -> t. Earlier, the extraction was using a shortcut to get the sort of t (via some mind_arity stuff), but this was producing a less precise answer (here InType) than a full Retyping.get_sort_family_of (here InProp since t is a singleton type, with no content). The extraction of t was hence awkward, since the type of the constructor T was computed with the precise method, and its argument was optimized out. Now the whole t is considered logical by the extraction. NB: to avoid this clever but highly non-intuitive behavior of Coq placing the above t in Prop, for the moment you have to fix its sort, for instance: Inductive t : Set := T : t -> t. Using Type instead of Set still activates Coq's minimal sort detection... Instead, you could also use one specific TypeX obtained via Definition TypeX := Type. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16203 85f007b7-540e-0410-9357-904b9bb8a0f7

* Actually adding backtrace handling.Gravatar ppedrot2013-01-28
| | | | | | | I hope I did not forget some [with] clauses. Otherwise, some stack frame will be missing from the debug. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16167 85f007b7-540e-0410-9357-904b9bb8a0f7
* Added backtrace primitives.Gravatar ppedrot2013-01-28
| | | | | | | | | | | | | | | | | | | | | | Using OCaml 3.11+ builtin facilities to record stack frames during exception raising, we can now recover at runtime the backtrace of an uncaught toplevel exception and display it to the user, without the infamous OCaml debugger. The backtrace is displayed when using the [-debug] flag. This requires a bit of discipline, as each time we reraise an exception we need to keep track of those frames we discarded between the previous raise and the current [try-with] branch. Currently, only [Anomaly] is handled, but this can be ported to any exception as long as we add the backtrace info into the exception, and we provide the corresponding handler to [Backtracke.register_backtrace_handler]. Hopefully this should not be to costly, as we only do little work when reraising, and only with the [-debug] flag set. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16166 85f007b7-540e-0410-9357-904b9bb8a0f7
