Fixes #8736.

Lintian found some spelling errors in the Debian packaging for coq. Fix
them most places they appear in the current source. (Don't change
documentation anchor names, as that would invalidate external
deeplinks.)
This also fixes a bug in coqdoc: prior to this commit, coqdoc would
highlight `instanciate` but not `instantiate`.

Hopefully this goes away when OCAMLPATH is properly handled by the
build system.

This refines the fix to #2169 by distinguishing the short and
non-short printing modes.
This prepares functionalization of printers by always passing env
rather than setting env to None in short mode. This is not strictly
necessary for the env which is not used for printing global references
but it shall be more consistent in style when passing e.g. the nametab
functionally.
We however keep the fallback printer used in case of error while
printing: due to missing registration of submodule fields in the
nametab, printing with types does not work if there are references to
an inner module.

We refactor the `Coqlib` API to locate objects over a namespace
`module.object.property`.
This introduces the vernacular command `Register g as n` to expose the
Coq constant `g` under the name `n` (through the `register_ref`
function). The constant can then be dynamically located using the
`lib_ref` function.

This fixes an obvious bug introduced in #8602.

This is slightly more robust and allows to run the test suite with
Dune which may place OCaml objects differently.

Note that since this now reduces before restricting universes
behaviour may be a bit different.

See commit [Simplify code for [Definition := Eval ...]] which without
this breaks test suite 7631.v

- Simplex based linear prover
Unset Simplex to get Fourier elimination
For lia and nia, do not enumerate but generate cutting planes.
- Better non-linear support
Factorisation of the non-linear pre-processing
Careful handling of equation x=e, x is only eliminated if x is used linearly
- More opaque interfaces
(Linear solvers Simplex and Mfourier are independent)
- Set Dump Arith "file" so that lia,nia calls generate Coq goals
in filexxx.v. Used to collect benchmarks and regressions.
- Rationalise the test-suite
example.v only tests psatz Z
example_nia.v only tests lia, nia
In both files, the tests are in essence the same.
In particular, if a test is solved by psatz but not by nia,
we finish the goal by an explicit Abort.
There are additional tests in example_nia.v which require specific
integer reasoning out of scope of psatz.

They were allowed to stay in terms in some cases. We now ensure that if
an evar is defined as e.g. fun x => Type@{foo}, foo is properly
refreshed to be non-algebraic as it could otherwise appear in the term
and break the invariant.
Also cleanup the implementation of refresh_universes to avoid using a
mutable reference and simply rely on the Constr.map smartmap idiom
instead.
This might have compatibility issues, e.g. in HoTT where maybe more
non-algebraic proxy universes could be generated, we'll see.
For the bug report proper, there is a lack of bidirectional
type-checking that makes the initial definition fail (there's a
non-canonical choice of dependency if we don't consider the typing
constraint). With the Program bidir hint it passes.

We remove sections paths from kernel names. This is a cleanup as most of the times this information was unused. This implies a change in the Kernel API and small user visible changes with regards to tactic qualification. In particular, the removal of "global discharge" implies a large cleanup of code.
Additionally, the change implies that some machinery in `library` and `safe_typing` must now take an `~in_section` parameter, as to provide the information whether a section is open or not.

compat updates to do as part of a release.
|
|
Also test that the compat updating script hasn't become outdated on the
CI.
|
|
Mostly via `dev/tools/update-compat.py --cur-version=8.9`
We just remove test-suite/success/FunindExtraction_compat86.v because,
except for the `Extraction iszero.` line at the bottom, it is a
duplicate of `test-suite/success/Funind.v` (except with `-compat 8.6`).
We also manually update a number of test-suite files to pre-emptively
remove compatibility notations (which used to be compat 8.6, but are now
compat 8.7).
|
|
All changes done with
```
git grep --name-only 'compat "8.6"' | xargs sed -i s'/compat "8.6"/compat "8.7"/g'
```
As per https://github.com/coq/coq/pull/8374#issuecomment-426202818 and
https://github.com/coq/coq/issues/8383#issuecomment-426200497

return clause
|
|
|
|
The no-inversion and maximal abstraction over dependencies now
supports abstraction over goal variables rather than only on "rel"
variables. In particular, it now works consistently using
"intro H; refine (match H with ... end)" or
"refine (fun H => match H with ... end)".
By doing so, we ensure that all three strategies are tried in all
situations where a return clause has to be inferred, even in the
context of a "refine".
See antepenultimate commit for discussion.
