2013-09-18At least made the evar type opaque! There are still 5 remaining unsafeppedrot
casts of ints to evars. - 2 in Evarutil and Goal which are really needed, even though the Goal one could (and should) be removed; - 2 in G_xml and Detyping that are there for completeness sake, but that might be made anomalies altogether; - 1 in Newring which is quite dubious at best, and should be fixed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16786 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-08-25Added a more efficient way to recover the domain of a map.ppedrot
The extended signature is defined in CMap, and should be compatible with the old one, except that module arguments have to be explicitely named. The implementation itself is quite unsafe, as it relies on the current implementation of OCaml maps, even though that should not be a problem (it has not changed in ages). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16735 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-08-08State Transaction Machinegareuselesinge
The process_transaction function adds a new edge to the Dag without executing the transaction (when possible). The observe id function runs the transactions necessary to reach to the state id. Transaction being on a merged branch are not executed but stored into a future. The finish function calls observe on the tip of the current branch. Imperative modifications to the environment made by some tactics are now explicitly declared by the tactic and modeled as let-in/beta-redexes at the root of the proof term. An example is the abstract tactic. This is the work described in the Coq Workshop 2012 paper. Coq is compile with thread support from now on. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16674 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-08-08Future library to represent pure computationsgareuselesinge
Since the whole system is imperative, futures are run protecting the global state, and the final state is also saved to let the user freely chain futures. Futures can represent local (lazy) computations or remote ones (delegated). Delegating a future lets a third party assign its value at some poit in the future; in the meanwhile accessing the future value raises an exception. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16669 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-06-06Uniformizing generic argument types.ppedrot
Now, instead of having three unrelated types describing a dynamic type at each level (raw, glob, top), we have a "('a, 'b, 'c) genarg_type" whose parameters describe the reified type at each level. This has various advantages: - No more code duplication to handle the three level separately; - Safer code: one is not authorized to mix unrelated types when what was morally expected was a genarg_type. - Each level-specialized representation can be accessed through well-typed projections: rawwit, glbwit and topwit.

2013-05-09A uniformization step around understand_* and interp_* functions.herbelin
- Clarification of the existence of three algorithms for solving unconstrained evars: - the type-class mechanism - the heuristics for solving pending conversion problems and multi-candidates - Declare Implicit Tactic (when called from tactics) Main function for solving unconstrained evars (when not using understand): Pretyping.solve_remaining_evars - Clarification of the existence of three corresponding kinds of errors when reporting about unsolved evars: Main function for checking resolution of evars independently of the understand functions: Pretyping.check_evars_are_solved - Introduction of inference flags in pretyping for governing which combination of the algorithms to use when calling some understand function; there is also a flag of expanding or not evars and for requiring or not the resolution of all evars - Less hackish way of managing Pretyping.type_constraint: all three different possibilities are now represented by three different constructors - Main semantical changes done: - solving unconstrained evars and reporting is not any longer mixed: one first tries to find unconstrained evars by any way possible; one eventually reports on the existence of unsolved evars using check_evars_are_solved - checking unsolved evars is now done by looking at the evar map, not by looking at the evars occurring in the terms to pretype; the only observed consequence so far is in Cases.v because of subterms (surprisingly) disappering after compilation of pattern-matching - the API changed, see dev/doc/changes.txt Still to do: - Find more uniform naming schemes: - for distinguishing when sigma is passed as a reference or as a value (are used: suffix _evars, prefix e_) - for distinguishing when evars are allowed to remain uninstantiated or not (are used: suffix _evars, again, suffix _tcc, infix _open_) - be more consistent on the use of names evd/sigma/evars or evdref/evars - By the way, shouldn't "understand" be better renamed into "infer" or "preinfer", or "pretype". Grammatically, "understanding a term" looks strange. - Investigate whether the inference flags in tacinterp.ml are really what we want (e.g. do we really want that heuristic remains activated when typeclasses are explicitly deactivated, idem in Tacinterp.interp_open_constr where flags are strange). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16499 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-03-21Robust display of NotConvertibleTypeField errors (fix #3008, #2995)letouzey
Since the nametab isn't aware of everything needed to print mismatched types (cf the bug test-cases), we create a robust term printer that known how to print a fully-qualified name when [shortest_qualid_of_global] has failed. These Printer.safe_pr_constr and alii are meant to never fail (at worse they display "??", for instance when the env isn't rich enough). Moreover, the environnement may have changed between the raise of NotConvertibleTypeField and its display, so we store the original env in the exception. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16342 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-01-28Added backtrace primitives.ppedrot
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
