2015-05-29STM/Univ: save initial univs (the ones in the statement) in Proof.proofEnrico Tassi
This makes the treatment of universe constraints/normalization more understandable in the Sync/Async case: - if one has to keep the constraints of the body and the type of a lemma separate, then equations coming from the body are kept (see: 866c41 ) - if they can be merge then the equations (substituted on both the body and type) can be removed (one of the sides occurs nowhere) The result is that, semantically, the constraints of a lemma do not depend on weather it was produced asynchronously (v->vio->vo, or in a CoqIDE session) or synchronously (v->vo). Still the internal representation of the constraints changes to accommodate an optimization (to reduce the size of the constraint set): - in the synchronous case (some) equations are substituted (in both the type and body), hence they can be completely dropped from the constraint set - in the asynchronous case (some) equations are substituted in the body only (the type is fixed once and for all before the equations are discovered/generated), hence these equations are necessary to relate the type and the (optimized) body and are hence kept in the constraint set
2015-05-27Fix bug #4159Matthieu Sozeau
Some asynchronous constraints between initial universes and the ones at the end of a proof were forgotten. Also add a message to print universes indicating if all the constraints are processed already or not.

2015-05-14Disable precompilation for native_compute by default.Guillaume Melquiond
Note that this does not prevent using native_compute, but it will force on-the-fly recompilation of dependencies whenever it is used. Precompilation is enabled for the standard library, assuming native compilation was enabled at configuration time. If native compilation was disabled at configuration time, native_compute falls back to vm_compute. Failure to precompile is a hard error, since it is now explicitly required by the user.
2015-05-13Safer typing primitives.Pierre-Marie Pédrot
Some functions from pretyping/typing.ml and their derivatives were potential source of evarmap leaks, as they dropped their resulting evarmap. This commit clarifies the situation by renaming them according to a unsafe_* scheme. Their sound variant is likewise renamed to their old name. The following renamings were made. - Typing.type_of -> unsafe_type_of - Typing.e_type_of -> type_of - A new e_type_of function that matches the e_ prefix policy - Tacmach.pf_type_of -> pf_unsafe_type_of - A new safe pf_type_of function. All uses of unsafe_* functions should be eventually eliminated.
2015-05-06Exposing the minimal amount of internal of the Logic monad in order toPierre-Marie Pédrot
allow reusability of the implementation throughout the Coq codebase. We effectively feature a generalized version of the logical monad where the input state, the output state and the inner exception can be arbitrarily chosen. This will allow for more efficient implementations of close variants of the monad.

2015-04-23Remove almost all the uses of string concatenation when building error messages.Guillaume Melquiond
Since error messages are ultimately passed to Format, which has its own buffers for concatenating strings, using concatenation for preparing error messages just doubles the workload and increases memory pressure.
2015-04-22Tactical `progress` compares term up to potentially equalisable universes.Arnaud Spiwack
Followup of: f7b29094fe7cc13ea475447bd30d9a8b942f0fef . In particular, re-closes #3593. As a side effect, fixes an undiscovered bug of the `eq_constr` tactic which didn't consider terms up to evar instantiation.

- no more inconsistent Axiom in the Prelude - STM can now process Admitted proofs asynchronously - the quick chain can stock "Admitted" jobs in .vio files - the vio2vo step checks the jobs but does not stock the result in the opaque tables (they have no slot) - Admitted emits a warning if the proof is complete - Admitted uses the (partial) proof term to infer section variables used (if not given with Proof using), like for Qed - test-suite: extra line Require TestSuite.admit to each file making use of admit - test-suite/_CoqProject: to pass to CoqIDE and PG the right -Q flag to find TestSuite.admit

2015-02-27Adding a new folder corresponding to the low-level part of the pretyperPierre-Marie Pédrot
together with the tactic monad. The move is not complete yet, because some file candidates for this directory have almost useless dependencies in other ones that should not be moved.
2015-02-24[Proofview.tclPROGRESS]: do not consider that trivial goal instantiation is ↵Arnaud Spiwack
progress. Also compare goals up to evar instantiation (otherwise no progress would be observed when only unification occurs, unless some [nf_evar] is done). Performance look unchanged so far. Some code from [Evd] which was used only in [tclPROGRESS] have been moved out (and [progress_evar_map] was now dead, so I killed it). Fixes bugs (one reported directly on coqdev, and #3412).

2014-12-28Call nf_constraints also when compiling directly to voEnrico Tassi
After commit b46944e the system got way slower, hence the optimization is relevant also for non polymorphic constants. Putting it back now, but we shall find something in between: an optimization that does not clash with async proofs but that gives some performance improvement over no optimization at all.
2014-12-28Proof using: call "clear" to remove from sight the vars not selectedEnrico Tassi
As discussed on coqdev, clear is not perfect, Hints for trivial using cleared section vars are still used. But it is better than nothing I guess.

2014-12-27proof_global: make it possible to call close_proof in a workerEnrico Tassi
Given that the proof state contains a callback (a terminator) that is not sent (dropped by the ephemeron mechanism at marshall time) de-referencing the ephemeron during this function makes it impossible to call it in a worker. Now the worker can call the function and replace the terminator with a good one.
2014-12-26Call Evd.nf_constraints only on Univ Poly constantsEnrico Tassi
When one generates a .vi file only the type is stocked. When one completes a .vi the proof term is stocked but the corresponding type is not changed: - if one minimizes the constraints of the body, the minimization could find that 2 univs are equal and substitute one for the other in the body, but it should also apply the subst to the type orelse coqchk could fail - also, a "retroactive" change of a type (making it stricter) invalidates what was type checked afterwards, so this operation clashes with the vi2vo compilation chain Hence we enable this optimization only for universe polymorphic constants that: - are the ones that truly requires such optimization - are never processed asynchronously, so the scenario above does not apply

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.
2014-12-12Make sure the goals on the shelve are identified as goal and unresolvable ↵Arnaud Spiwack
for typeclasses. This was not the case for goals created at the end of the tactic by salvaging the [future_goals] from the evar map. It would cause typeclass resolution to try and solve these goals (if they have a class type) at each subsequent tactic. Fixes #3841.

propagate it. This allows C-zar to continue to work. Don't know if it is the best way to do it.
2014-12-04Occur-check in refine.Arnaud Spiwack
The occur check is done even if the flag [unsafe] is set to true. The rational is that a tactic cannot control where it takes pieces of terms from (and hence will not generally make terms which pass the occur-check), and it would be painful to ask every tactic which takes a term as an argument to do an occur check before [refine]. I reused the same error than used by unification. It gives a pretty nice error message. An alternative would be to have a dedicated error with pretty much the same error message. I'm not sure which is best, so I went for the simplest one. The same check is done in the compatibility layer. Fixes a reported bug which I cannot locate for some reason.
