* Added a more efficient way to recover the domain of a map.Gravatar ppedrot2013-08-25
| | | | | | | | | | 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

* Misc changes around coqtop.ml :Gravatar letouzey2013-08-22
| | | | | | | | | | | | | | | | | | | - Revised Coqtop.parse_args in a cleaner and lighter style - Improved error message in case of argument parse failure: * tell which option is expecting a related argument * in case of unknown options, warn about them all at once * do not hide the previous error messages by filling the screen with usage(). Instead, suggest the use of --help. - Specialized boolean config field Coq_config.arch_is_win32 - Faster Envars.coqlib, which is back to (unit->string), and just access Flags.coqlib. Caveat: it must be initialized once via Envars.set_coqlib - Avoid keeping an opened channel to the "revision" file - Direct load of theories/init/prelude.vo, no detour via Loadpath Beware : ./configure must be runned after this commit git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16726 85f007b7-540e-0410-9357-904b9bb8a0f7
* Change in vo format : digest aren't Marshalled anymoreGravatar letouzey2013-08-22
| | | | | | | | | | | Since digests are strings (of size 16), we just dump them now in vo files (cf. Digest.output) instead of using Marshal on them : this is cleaner and saves a few bytes. Increased VOMAGIC to clearly identify this change in the format.

* Declarations.mli: reorganization of modular structuresGravatar letouzey2013-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The earlier type [struct_expr_body] was far too broad, leading to code with unclear invariants, many "assert false", etc etc. Its replacement [module_alg_expr] has only three constructors: * MEident * MEapply : note the module_path as 2nd arg, no more constraints here * MEwith : no more constant_body inside, constr is just fine But no more SEBfunctor or SEBstruct constructor here (see below). This way, this datatype corresponds to algebraic expressions, i.e. anything that can appear in non-interactive modules. In fact, it even coincides now with [Entries.module_struct_entry]. - Functor constructors are now necessarily on top of other structures thanks to a generic [functorize] datatype. - Structures are now separated from algebraic expressions by design : the [mod_type] and [typ_expr] fields now only contain structures (or functorized structures), while [mod_type_alg] and [typ_expr_alg] are restricted to algebraic expressions only. - Only the implementation field [mod_expr] could be either algebraic or structural. We handle this via a specialized datatype [module_implementation] with four constructors: * Abstract : no implementation (cf. for instance Declare Module) * Algebraic(_) : for non-interactive modules, e.g. Module M := N. * Struct(_) : for interactive module, e.g. Module M : T. ... End M. * FullStruct : for interactive module with no type restriction. The [FullStruct] is a particular case of [Struct] where the implementation need not be stored at all, since it is exactly equal to its expanded type present in [mod_type]. This is less fragile than hoping as earlier that pointer equality between [mod_type] and [mod_expr] will be preserved... - We clearly emphasize that only [mod_type] and [typ_expr] are relevant for the kernel, while [mod_type_alg] and [typ_expr_alg] are there only for a nicer extraction and shorter module printing. [mod_expr] is also not accessed by the kernel, but it is important for Print Assumptions later. - A few implicit invariants remain, for instance "no MEwith in mod_expr", see the final comment in Declarations - Heavy refactoring of module-related files : modops, mod_typing, safe_typing, declaremods, extraction/extract_env.ml ... - Coqchk has been adapted accordingly. The code concerning MEwith in Mod_checking is now gone, since we cannot have any in mod_expr. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16712 85f007b7-540e-0410-9357-904b9bb8a0f7

* State Transaction MachineGravatar gareuselesinge2013-08-08
| | | | | | | | | | | | | | | | | | | | | 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
* Declaremods: major refactoring, stop duplicating libobjects in modulesGravatar letouzey2013-07-17
| | | | | | | | | | | | | | | | | | | | | | | When refering to a module / module type, or when doing an include, we do not duplicate and substitution original libobjects immediatly. Instead, we store the module path, plus a substitution. The libobjects are retrieved later from this module path and substituted, typically during a Require. This allows to vastly decrease vo size (up to 50% on some files in the stdlib). More work is done during load (some substitutions), but the extra time overhead appears to be negligible. Beware: all subst_function operations should now be environment-insensitive, since they may be arbitrarily delayed. Apparently only subst_arguments_scope had to be adapted. A few more remarks: - Increased code factorisation between modules and modtypes - Many errors and anomaly are now assert - One hack : brutal access of inner parts of module types (cf handle_missing_substobjs) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16630 85f007b7-540e-0410-9357-904b9bb8a0f7

* Revised infrastructure for lazy loading of opaque proofsGravatar letouzey2013-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of the LightenLibrary hack : no more last-minute collect of opaque terms and Obj.magic tricks. Instead, we make coqc accumulate the opaque terms as soon as constant_bodies are created outside sections. In these cases, the opaque terms are placed in a special table, and some (DirPath.t * int) are used as indexes in constant_body. In an interactive session, the local opaque terms stay directly stored in the constant_body. The structure of .vo file stays similar : magic number, regular library structure, digest of the first part, array of opaque terms. In addition, we now have a final checksum for checking the integrity of the whole .vo file. The other difference is that lazy_constr aren't changed into int indexes in .vo files, but are now coded as (substitution list * DirPath.t * int). In particular this approach allows to refer to opaque terms from another library. This (and accumulating substitutions in lazy_constr) seems to greatly help decreasing the size of opaque tables : -20% of vo size on the standard library :-). The compilation times are slightly better, but that can be statistic noise. The -force-load-proofs isn't active anymore : it behaves now just like -lazy-load-proofs. The -dont-load-proofs mode has slightly changed : opaque terms aren't seen as axioms anymore, but accessing their bodies will raise an error. Btw, API change : Declareops.body_of_constant now produces directly a constr option instead of a constr_substituted option git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16382 85f007b7-540e-0410-9357-904b9bb8a0f7

* Restrict (try...with...) to avoid catching critical exn (part 1)Gravatar letouzey2013-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | Why? : avoid catching (and probably ignoring) exceptions such as Sys.Break, anomalies, assertions, leading to undetected bugs and ignored Ctrl-C. How? : when the precise exception(s) concerned by the try is known, use them explicitely in the "with". Otherwise, let's use the pattern "with e when Errors.noncritical e -> " Particular case : when an exception is catched and reraised immediately after some adjustments, we leave it untouched. Simply, for easily identifying these situations later, the name of the exception variable is changed to "reraise". Please also adopt this coding style. Automatic checks based on the "mascot" tool of X. Clerc will be runned regularly. If you want to avoid to check a particular try...with, use the variable name "any" after the "with". All these changes have been tested using the standard library and the test-suite, but unfortunately this is far from ensuring that coqtop behaves as before. We'll see after the nightly bench... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16276 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
