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.

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.

Without this commit, passing "-R theories Coq" to "coqtop -nois" has no
effect since "-Q theories Coq" has already been done implicitly.

Also removed the require function it was using, as it is absent from the
remaining of the code.

The new behaviour is simple: either a path is in the loadpaths or it is not.
No more wild expansions of paths!
This should not affect -R and -Q, but it does change the semantics of -I -as.
Still, there are no more users of it and it only does so in a subtle way.

It is still present in the libstack, though.

We explicit the fact that we only need the name of the library in most of the
summaries.

- 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

Workers send back incomplete system states (only the proof part).
Such part must include the meta/evar counter.

Instead of registering all the transitive dependencies of a term in one go,
we rather recursively build the graph of direct dependencies of this term.
This is finer-grained and offers a better API.
The traversal now uses the standard term fold operation, and also registers
inductives and constructors encountered in the traversal.

Of course such proofs cannot be processed asynchronously

This is done by adding a fourth type of loadpath, the ones that are
neither implicit nor root, for the subdirectories of a -Q root.
Note: this means that scanning for available directories is no longer done
on the fly for -Q, but once and for all, as with -R.

optimized. Now "Import Arith ZArith" imports only once the libraries
reexported by both Arith and ZArith. (No side effect can be inserted
here, so that this looks compatible).

This reverts commit 6d5b56d971506dfadcfc824bfbb09dc21718e42b but does not put

After this commit, module_type_body is a particular case of module_type.
For a [module_type_body], the implementation field [mod_expr] is
supposed to be always [Abstract]. This is verified by coqchk, even
if this isn't so crucial, since [mod_expr] is never read in the case
of a module type.
Concretely, this amounts to the following rewrite on field names
for module_type_body:
- typ_expr --> mod_type
- typ_expr_alg --> mod_type_alg
- typ_* --> mod_*
and adding two new fields to mtb:
- mod_expr (always containing Abstract)
- mod_retroknowledge (always containing [])
This refactoring should be completely transparent for the user.
Pros: code sharing, for instance subst_modtype = subst_module.
Cons: a runtime invariant (mod_expr = Abstract) which isn't
enforced by typing. I tried a polymorphic typing of mod_expr,
to share field names while not having mtb = mb, but the OCaml
typechecker isn't clever enough with polymorphic mutual fixpoints,
and reject code sharing (e.g. between subst_modtype and subst_module).
In the future (with ocaml>=4), some GADT could maybe help here,
but for now the current solution seems good enough.

Removing unused argument and fixing bug #3899, now warning when a record
cannot be made primitive in Set Primitive Projections mode because it
has no projection or at least one undefinable projection.

Fixes #3379 and part of #3363. Also avoids fragile code propagating required
libraries when closing an interactive module.
Had to fix a few occurrences in std lib.

API to let one forge a frozen state out of another frozen state
plus some frozen bits
|
|
In this way one can make surgery on the system states, like
checking if two frozen states have the same environment (i.e.
no running "abstract" in between)

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.

Patch by CJ on bugzilla. CUnix.sys_command doesn't rely on a shell, so extra
care with cmd.exe vs sh is no longer required.

- Registering strict implicit arguments systematically (35fc7d728168)
- Experimenting always forcing convertibility on strict implicit arguments (a1a6d7b99eef5e6)
- Fixing Coq compilation (894a3d16471)
Systematically computing strict implicit arguments can lead to big
computations, so I suspend this attempt, waiting for improved
computation of implicit arguments, or alternative heuristics going
toward having more conversion in rewrite.

inductive types (i.e., ones declared with an explicit anonymous Type
at the conclusion of their arity). With this change one can force
inductives to live in higher universes even in the non-fully universe
polymorphic case (e.g. bug #3821).
|
|
This is a continuation of the previous patch.
