2020-06-30[states] Move States to vernacEmilio Jesus Gallego Arias
We continue to push state layers upwards, in preparation of a functional vernacular interpretation. Now we move `States` and `Printmod` which messes with the global state as to temporarily create envs with modules.

Add headers to a few files which were missing them.
2020-03-03[exninfo] Deprecate aliases for exception re-raising.Emilio Jesus Gallego Arias
We make the primitives for backtrace-enriched exceptions canonical in the `Exninfo` module, deprecating all other aliases. At some point dependencies between `CErrors` and `Exninfo` were a bit complex, after recent clean-ups the roles seem much clearer so we can have a single place for `iraise` and `capture`.

2019-08-30[library] Move library to vernacEmilio Jesus Gallego Arias
This is step 1 on removing library state from the lower layers. Here we move library loading to the vernacular layer; few things depend on it: - printers: we add a parameter for those needing to access on-disk data, - coqlib: indeed a few tactics do try to check that a particular library is loaded; this is a tricky part. I've replaced that for a module name check, but indeed this is fully equivalent due to side-effects of `Require`. We may want to think what to do here. A few other minor code movements were needed, but there are self-explanatory.

2017-10-17[stm] Remove state-handling from Futures.Emilio Jesus Gallego Arias
We make Vernacentries.interp functional wrt state, and thus remove state-handling from `Future`. Now, a future needs a closure if it wants to preserve state. Consequently, `Vernacentries.interp` takes a state, and returns the new one. We don't explicitly thread the state in the STM yet, instead, we recover the state that was used before and pass it explicitly to `interp`. I have tested the commit with the files in interactive, but we aware that some new bugs may appear or old ones be made more apparent. However, I am confident that this step will improve our understanding of bugs. In some cases, we perform a bit more summary wrapping/unwrapping. This will go away in future commits; informal timings for a full make: - master: real 2m11,027s user 8m30,904s sys 1m0,000s - no_futures: real 2m8,474s user 8m34,380s sys 0m59,156s

2015-09-29Make the interface of System.raw_extern_intern much saner.Guillaume Melquiond
There is no reason (any longer?) to create simultaneous closures for interning and externing files. This patch makes the code more readable by separating both functions and their signatures.

in the loadpath. This patch causes a bit of code duplication (because of the .coq suffix added to state files) but it makes it clear which part of the code is looking up files in the loadpath and for what purpose. Also it makes the interface of System.extern_intern and System.raw_extern_intern much saner.

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.

2013-08-08State 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

2013-04-02Revised infrastructure for lazy loading of opaque proofsletouzey
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

2011-04-03Lazy loading of opaque proofs: fast as -dont-load-proofs without its drawbacksletouzey
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
