The exception needs to carry aroud a pair of `env, sigma` so printing
is correct. This gets rid of a few global calls, and it is IMO the
right thing to do.
While we are at it, we incorporate some fixes to a couple of
additional printing functions missing the `env, sigma` pair.

New module introduced in OCaml 4.05 I think, can create problems when
linking with the OCaml toplevel for `Drop`.

In the test we do [let X : Type@{i} := Set in ...] with Set
abstracted. The constraint [Set < i] was lost in the abstract.
Universes of a monomorphic reference [c] are considered to appear in
the term [c].

The patch has three parts:
- Introduction of a configure flag `-bytecode-compiler (yes|no)`
(due to static initialization this is a configure-time option)
- Installing the hooks that register the VM with the pretyper and the
kernel conditionally on the flag.
- Replacing the normalization function in `Redexpr` by compute if the
VM is disabled.
We also rename `Coq_config.no_native_compiler` to `native_compiler`
and `Flags.native_compiler` to `output_native_objects` [see #4607].

- Regularly declared for for polymorphic constants
- Declared globally for monomorphic constants.
E.g mono@{i} := Type@{i} is printed as
mono@{mono.i} := Type@{mono.i}.
There can be a name clash if there's a module and a constant of the
same name. It is detected and is an error if the constant is first
but is not detected and the name for the constant not
registered (??) if the constant comes second.
Accept VarRef when registering universe binders
Fix two problems found by Gaëtan where binders were not registered properly
Simplify API substantially by not passing around a substructure of an
already carrier-around structure in interpretation/declaration code of
constants and proofs
Fix an issue of the stronger restrict universe context + no evd leak
This is uncovered by not having an evd leak in interp_definition, and
the stronger restrict_universe_context. This patch could be backported
to 8.7, it could also be triggered by the previous restrict_context I
think.

In particular `Proof_global.t` will become a first class object for
the upper parts of the system in a next commit.

This reduces conversions between ContextSet/UContext and encodes
whether we are polymorphic by which constructor we use rather than
using some boolean.
|
| | |
| |
| |
| |
| |
| |
| |
| | |
Also use constant_universes_entry instead of a bool flag to indicate
polymorphism in ParameterEntry.
There are a few places where we convert back to ContextSet because
check_univ_decl returns a UContext, this could be improved.
|
| | |
| |
| |
| |
| |
| | |
We can enforce properties through check_univ_decl, or get an arbitrary
ordered context with UState.context / Evd.to_universe_context (the
later being a new wrapper of the former).

We mirror the structure of EConstr and move the destructors from `Term`
to `Constr`.
This is a step towards having a single module for `Constr`.

I followed what seems to be the intention of the code, with the
original intention of remove the global imperative proof state.
However, I fully fail to see why the new API is better than the old
one. In fact the opposite seems the contrary.
Still big parts of the "new proof engine" seem unfinished, and I'm
afraid I am not the right person to know what direction things should
take.

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:

We place `Proof_using` in the proper place [`vernac`] and we remove
gross parsing hacks.
The new placement should allow to use the printers and more convenient
structure, and reduce strange coupling between parsing and internal
representation.

Also add an output test for Suggest Proof Using.
This changes the .aux output: instead of getting a key
>context_used "$hyps;$suggest"
where $hyps is a list of the used hypotheses and $suggest is the
;-separated suggestions (or the empty string if Suggest Proof Using is
unset), there is a key
>context_used "$hyps"
and if Suggest Proof Using is set also a key
>suggest_proof_using "$suggest"
For instance instead of
112 116 context_used "B A;A B;All"
we get
112 116 context_used "B A"
112 116 suggest_proof_using "A B;All"

The old algorithm was relying on list membership, which is O(n). This was
nefarious for terms with many binders. We use instead sets in O(log n).

Introduce a "+" modifier for universe and constraint declarations to
indicate that these can be extended in the final definition/proof. By
default [Definition f] is equivalent to [Definition f@{+|+}], i.e
universes can be introduced and constraints as well. For [f@{}] or
[f@{i j}], the constraints can be extended, no universe introduced, to
maintain compatibility with existing developments. Use [f@{i j | }] to
indicate that no constraint (nor universe) can be introduced. These
kind of definitions could benefit from asynchronous processing.
Declarations of universe binders and constraints also works for
monomorphic definitions.

Because the argument given to refine may mess with the evarmap, the goal being
refined can be solved by side-effect after the term filler is computed. If this
happens, we simply don't perform the refining operation.

We use an algebraic type instead of a pair of a boolean and the corresponding
data. For now, this is isomorphic, but this allows later change in the structure.

We sort the dependency graph of API by following a logical declaration
order in `API.{ml,mli}` related to the actual dependency order of Coq
modules.
Things are a bit tricky here as Coq itself relies on the fact that
OCaml treats module interface and implementation separately
dependency-wise; however, when resorting module alias the design seems
to become more coupled.
Currently, API exposes both "namespaces", asserting a large number of
type equality between them, however the `API` namespace is not
self-contained.
In particular, this is a first step to solve problems such as
`Summary.frozen` being used in `API.mli` but not declared by the
`API.Summary` module, etc... In general we follow the invariant that a
type used in `API` must have been declared before.
Keep in mind that OCaml upstream has warned that it maybe tricky to
alias objects in this way. In particular, after API the old `mli` only
files have become full compilation units so we may want to be more
careful here.
The more "correct" declaration order allows us to remove the
`API.Prelude` module, as well as some other declarations that I
consider as spurious.
We still maintain the large number of type aliases which will be
removed in a future patch.
We follow linking order except for files in `intf`, which are
conceptually wrongly placed in the linking hierarchy but this doesn't
matter as the files don't contain any implementation.
We also move a couple of `.mli` only files to `.ml` so we are
consistent, and correct their linking order in `mllib`, even if that
doesn't matter as such `.ml`-only files contain no implementations.
