2015-06-23Moved fatal_error from Coqtop to Errors and corrected dependencies accordingly.Thomas Sibut-Pinote
This allows fatal_error to be used for printing anomalies at loading time.

2014-12-16Getting rid of Exninfo hacks.Pierre-Marie Pédrot
Instead of modifying exceptions to wear additional information, we instead use a dedicated type now. All exception-using functions were modified to support this new type, in particular Future's fix_exn-s and the tactic monad. To solve the problem of enriching exceptions at raise time and recover this data in the try-with handler, we use a global datastructure recording the given piece of data imperatively that we retrieve in the try-with handler. We ensure that such instrumented try-with destroy the data so that there may not be confusion with another exception. To further harden the correction of this structure, we also check for pointer equality with the last raised exception. The global data structure is not thread-safe for now, which is incorrect as the STM uses threads and enriched exceptions. Yet, we splitted the patch in two parts, so that we do not introduce dependencies to the Thread library immediatly. This will allow to revert only the second patch if ever we switch to OCaml-coded lightweight threads.
2013-03-17Checker: simplify a bit its exception handlerletouzey
We use Errors.print for anomalies and other uncaught exceptions in the checker: this should print the same message, it is shorter this way, and we avoid using Errors.is_anomaly. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16310 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-03-14Embedded exns in LtacLocated and EvaluatedError satisfy Errors.noncriticalletouzey
This was apparently already the case before, but this invariant is now explicited in comments + a few asserts. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16305 85f007b7-540e-0410-9357-904b9bb8a0f7

For the moment, are considered critical : Sys.Break, Stack_overflow, Out_of_memory Assert_failure, Match_failure, Anomaly, Timeout, Drop, Exit These exceptions should normally *not* be catched by a "try", hence the suggested code for generic "try": try ... with e when Errors.noncritical e -> ... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16269 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-02-18Updating the backtrace handling mechanism to accomodate the newppedrot
exception information addition facility. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16213 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-01-28Actually adding backtrace handling.ppedrot
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

2012-06-22Added an indirection with respect to Loc in Compat. As many [open Compat]ppedrot
were closed (i.e. the only remaining ones are those of printing/parsing). Meanwhile, a simplified interface is provided in loc.mli. This also permits to put Pp in Clib, because it does not depend on CAMLP4/5 anymore. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15475 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-05-29Vernacexpr is now a mli-only file, locality stuff now in locality.mlletouzey
Adds a directory ./intf for pure interfaces. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15367 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-03-02Noise for nothingpboutill
Util only depends on Ocaml stdlib and Utf8 tables. Generic pretty printing and loc functions are in Pp. Generic errors are in Errors. + Training white-spaces, useless open, prlist copies random erasure. Too many "open Errors" on the contrary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15020 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-05-17More work on error handlingletouzey
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
2011-05-13A new mechanism to handle errors.aspiwack
Instead of the monolitic Cerrors, I introduce a lightweight Errors module whose error message can be expanded by module introducing exceptions. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14119 85f007b7-540e-0410-9357-904b9bb8a0f7
