Leonardo de Moura	993bea8206	refactor(library/elaborator): improve elaborator state data-structure The "quota" hack used before this commit was inefficient, and too hackish. This commit uses two lists of constraints: active and delayed. The delayed constraints are only processed when there are no active constraints. We use a simple index to quickly find which delayed constraints have assigned metavariables.

Leonardo de Moura	160a8379ef	feat(library/elaborator): provide the metavar_env to instantiate and lift_free_vars in the elaborator, it will minimize the number of local_entries needed The modifications started at commit `1852c86948` made a big difference. For example, before these changes test tests/lean/implicit7.lean generated complicated constraints such as: [x : Type; a : ?M::29[inst:1 ?M::0[lift:0:1]] x] ⊢ Pi B : Type, (Pi _ : x, (Pi _ : (?M::35[inst:0 #0, inst:1 #2, inst:2 #4, inst:3 #6, inst:5 #5, inst:6 #7, inst:7 #9, inst:9 #9, inst:10 #11, inst:13 ?M::0[lift:0:13]] x a B _), (?M::36[inst:1 #1, inst:2 #3, inst:3 #5, inst:4 #7, inst:6 #6, inst:7 #8, inst:8 #10, inst:10 #10, inst:11 #12, inst:14 ?M::0[lift:0:14]] x a B _ _))) ≈ ?M::22 x a After the changes, only very simple constraints are generated. The most complicated one is: [] ⊢ Pi a : ?M::0, (Pi B : Type, (Pi _ : ?M::0, (Pi _ : B, ?M::0))) ≈ Pi x : ?M::17, ?M::18 Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-12-14 15:59:35 -08:00

Leonardo de Moura	4357c9196e	feat(kernel/metavar): make sure that a metavariable 'm' can only be assigned to a term that contains free variables available in the context associated with 'm' This commit also simplifies the method check_pi in the type_checker and type_inferer. It also fixes process_meta_app in the elaborator. The problem was in the method process_meta_app and process_meta_inst. They were processing convertability constrains as equality constraints. For example, process_meta_app would handle ctx \|- Type << ?f b as ctx \|- Type =:= ?f b This is not correct because a ?f that returns (Type U) for b satisfies the first but not the second.

Leonardo de Moura	f97c260b0b	refactor(kernel/environment): add ro_environment The environment object is a "smart-pointer". Before this commit, the use of "const &" for environment objects was broken. For example, suppose we have a function f that should not modify the input environment. Before this commit, its signature would be void f(environment const & env) This is broken, f's implementation can easilty convert it to a read-write pointer by using the copy constructor. environment rw_env(env); Now, f can use rw_env to update env. To fix this issue, we now have ro_environment. It is a shared const pointer. We can convert an environment into a ro_environment, but not the other way around. ro_environment can also be seen as a form of documentation. For example, now it is clear that type_inferer is not updating the environment, since its constructor takes a ro_environment.

It has a theorem of the form: Theorem T1 (A B : Bool) : A /\ B -> B /\ A := fun assumption : A /\ B, let lemma1 := (show A by auto), lemma2 := (show B by auto) in (show B /\ A by auto) When to_goal creates a goal for the metavariable associated with (show B /\ A by auto) it receives a context and proposition of the form [ A : Bool, B : Bool, assumption : A /\ B, lemma1 := Conjunct1 assumption, lemma2 := Conjunct2 assumption ] \|- B /\ A The context_entries "lemma1 := Conjunct1 assumption" and "lemma2 := Conjunct2 assumption" do not have a domain (aka type). Before this commit, to_goal would simply replace and references to "lemma1" and "lemma2" in "B /\ A" with their definitions. Note that, "B /\ A" does not contain references to "lemma1" and "lemma2". Then, the following goal is created A : Bool, B : Bool, assumption : A /\ B \|- B /\ A That is, the lemmas are not available when solving B /\ A. Thus, the tactic auto produced the following (weird) proof for T1, where the lemmas are computed but not used. Theorem T1 (A B : Bool) (assumption : A ∧ B) : B ∧ A := let lemma1 := Conjunct1 assumption, lemma2 := Conjunct2 assumption in Conj (Conjunct2 assumption) (Conjunct1 assumption) This commit fixed that. It computes the types of "Conjunct1 assumption" and "Conjunct2 assumption", and creates the goal A : Bool, B : Bool, assumption : A /\ B, lemma1 : A, lemma2 : B \|- B /\ A After this commit, the proof for theorem T1 is Theorem T1 (A B : Bool) (assumption : A ∧ B) : B ∧ A := let lemma1 := Conjunct1 assumption, lemma2 := Conjunct2 assumption in Conj lemma2 lemma1 as expected. Finally, this example suggests that the encoding Theorem T1 (A B : Bool) : A /\ B -> B /\ A := fun assumption : A /\ B, let lemma1 : A := (by auto), lemma2 : B := (by auto) in (show B /\ A by auto) is more efficient than Theorem T1 (A B : Bool) : A /\ B -> B /\ A := fun assumption : A /\ B, let lemma1 := (show A by auto), lemma2 := (show B by auto) in (show B /\ A by auto) Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-12-06 16:14:25 -08:00

Leonardo de Moura	20a36e98ec	feat(library/elaborator): modify how elaborator handles constraints of the form ?M << P and P << ?M, where P is a proposition. Before this commit, the elaborator would only assign ?M <- P, if P was normalized. This is bad since normalization may "destroy" the structure of P. For example, consider the constraint [a : Bool; b : Bool; c : Bool] ⊢ ?M::1 ≺ implies a (implies b (and a b)) Before this, ?M::1 will not be assigned to the "implies-term" because the "implies-term" is not normalized yet. So, the elaborator would continue to process the constraint, and convert it into: [a : Bool; b : Bool; c : Bool] ⊢ ?M::1 ≺ if Bool a (if Bool b (if Bool (if Bool a (if Bool b false true) true) false true) true) true Now, ?M::1 is assigned to the term if Bool a (if Bool b (if Bool (if Bool a (if Bool b false true) true) false true) true) true This is bad, since the original structure was lost.

Leonardo de Moura	d87ad9eb7e	refactor(util/lua): propagate C++ Lean exceptions in Lua The following call sequence is possible: C++ -> Lua -> C++ -> Lua -> C++ The first block of C++ is the Lean main function. The main function invokes the Lua interpreter. The Lua interpreter invokes a C++ Lean API. Then the Lean API invokes a callback implemented in Lua. The Lua callback invokes another Lean API. Now, suppose the Lean API throws an exception. We want the C++ exception to propagate over the mixed C++/Lua call stack. We use the clone/rethrow exception idiom to achieve this goal. Before this commit, the C++ exceptions were converted into strings using the method what(), and then they were propagated over the Lua stack using lua_error. A lua_error was then converted into a lua_exception when going back to C++. This solution was very unsatisfactory, since all C++ exceptions were being converted into a lua_exception, and consequently the structure of the exception was being lost.

Leonardo de Moura	691893258d	feat(kernel/expr): add hash code based on allocation time The new hash code has the property that given expr_cell * c1 and expr_cell * c2, if c1 != c2 then there is a high propbability that c1->hash_alloc() != c2->hash_alloc(). The structural hash code hash() does not have this property because we may have c1 != c2, but c1 and c2 are structurally equal. The new hash code is only compatible with pointer equality. By compatible we mean, if c1 == c2, then c1->hash_alloc() == c2->hash_alloc(). This property is obvious because hash_alloc() does not have side-effects. The test tests/lua/big.lua exposes the problem fixed by this commit. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-11-14 02:43:11 -08:00

Leonardo de Moura	c4c548dc5d	feat(*): simplify interrupt propagation Instead of having m_interrupted flags in several components. We use a thread_local global variable. The new approach is much simpler to get right since there is no risk of "forgetting" to propagate the set_interrupt method to sub-components. The plan is to support set_interrupt methods and m_interrupted flags only in tactic objects. We need to support them in tactics and tacticals because we want to implement combinators/tacticals such as (try_for T M) that fails if tactic T does not finish in M ms. For example, consider the tactic: try-for (T1 ORELSE T2) 5 It tries the tactic (T1 ORELSE T2) for 5ms. Thus, if T1 does not finish after 5ms an interrupt request is sent, and T1 is interrupted. Now, if you do not have a m_interrupted flag marking each tactic, the ORELSE combinator will try T2. The set_interrupt method for ORELSE tactical should turn on the m_interrupted flag.

Leonardo de Moura	9a5f86fce6	feat(lua): use ( ... ) instead of {{ ... }} for nested Lua scripts The token }} is a bad delimiter for blocks of Lua script code nested in Lean files. The problem is that the sequence }} occurs very often in Lua code because Lua uses { and } to build tables/lists/arrays. Here is an example of Lua code that contains the sequence }} t = {{1, 2}, {2, 3}, {3, 4}} In Lean, (* ... ) is used to create comments. Thus, (* ... **) code blocks will not affect valid Lean files.

Leonardo de Moura	8012c4f644	fix(kernel/environment): add weak reference to environment objects We need weak references to environment objects because the environment has a reference to the type_checker and the type_checker has a reference back to the environment.

Leonardo de Moura	9c60eed93c	refactor(kernel/metavar): avoid using unique names for default metavariable prefix The problem is that unique names depend on the order compilation units are initialized. The order of initialization is not specified by the C++ standard. Then, different compilers (or even the same compiler) may produce different initialization orders, and consequently the metavariable prefix is going to be different for different builds. This is not a bug, but it makes unit tests to fail since the output produced by different builds is different for the same input file. Avoiding unique name feature in the default metavariable prefix avoids this problem. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-11-07 10:16:25 -08:00

Leonardo de Moura	fd7e85f0bb	feat(lua): add safe_function template that catches Lean and C++ exceptions and convert them into Lua errors I'm using the approach described at: http://stackoverflow.com/questions/4615890/how-to-handle-c-exceptions-when-calling-functions-from-lua BTW, in some Lua versions, the C++ exceptions are correctly propagated. I think we should not rely on features of particular implementations. For example, LuaJIT does not propagate C++ exceptions. Whenever an exception is thrown from C++ code invoked from LuaJit, LuaJit interrupts the execution and converts it to an error "C++ exception". On the other hand, Lua 5.2 PUC-Rio interpreter (for Ubuntu) seem to propagate the C++ exceptions. The template safe_function solves the issue. It will also produce a Lua error whenever the function being wrapped throws an exception. The error message is based on the "what()" method.

Leonardo de Moura	4dd6cead83	refactor(equality): make homogeneous equality the default equality It was not a good idea to use heterogeneous equality as the default equality in Lean. It creates the following problems. - Heterogeneous equality does not propagate constraints in the elaborator. For example, suppose that l has type (List Int), then the expression l = nil will not propagate the type (List Int) to nil. - It is easy to write false. For example, suppose x has type Real, and the user writes x = 0. This is equivalent to false, since 0 has type Nat. The elaborator cannot introduce the coercion since x = 0 is a type correct expression. Homogeneous equality does not suffer from the problems above. We keep heterogeneous equality because it is useful for generating proof terms. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-10-29 16:20:06 -07:00

Leonardo de Moura	ddb90d3038	feat(kernel): add unification_constraint and trace objects to the kernel Trace objects will be used to justify steps performed by engines such as the elaborator. We use them to implement non-chronological backtracking in the elaborator. They are also use to justify to the user why something did not work. The unification constraints are in the kernel because the type checker may create them when type checking a term containing metavariables. Remark: a minimalistic kernel does not need to include metavariables, unification constraints, nor trace objects. We include these objects in our kernel to minimize code duplication.

Soonho Kong	a2a5a77a44	fix(memory): increase memory counters by the actual size of reallocated memory On OSX, we had a test failure on memory module. The problem was in the realloc function (line 38): void * realloc(void * ptr, size_t sz) { size_t old_sz = malloc_size(ptr); g_global_memory.dec(old_sz); g_global_memory.inc(sz); g_thread_memory.dec(old_sz); g_thread_memory.inc(sz); void * r = realloc_core(ptr, sz); if (r \|\| sz == 0) return r; else ... The size of r could be bigger than sz. For instance, \|ptr\| = 40 but \|r\| = 48 In the current code, here we only increase counters by 40. But later when we free it, we decrease them by 48, and this caused the problem, underflow of an unsigned counter in g_global_memory.	2013-09-26 00:33:56 -07:00

Leonardo de Moura	9f0dab1add	fix(kernel): add declarations for operator<<(std::ostream&, expr const&) and operator<<(std::ostream&, context const&) in the kernel The actual implementation of these two operators is outside of the kernel. They are implemented in the file 'library/printer.cpp'. We declare them in the kernel to prevent the following problem. Suppose there is a file 'foo.cpp' that does not include 'library/printer.h', but contains expr a; ... std::cout << a << "\n"; ... The compiler does not generate an error message. It silently uses the operator bool() to coerce the expression into a Boolean. This produces counter-intuitive behavior, and may confuse developers.	2013-09-25 17:45:54 -07:00
