[WIP] Load rules lazily (#370) * Change jbuilder to load rules lazily Rules are now loaded on a per directory basis as needed. This speed up the start up time on large workspaces. Does various refactoring as well. * Simplify the handling of META files We no longer generate a META.foo.from-jbuilder file. Nobody is using this feature and it's making the new code more complicated. 2018-01-19 08:50:06 +00:00			`(* Generate rules. Returns evaluated jbuilds per context names. *)`

Refactor library management (#516) Lib module ---------- We have a new module Lib that replaces Lib, parts of Lib_db and parts of Findlib. It is used to manage all libraries (internal and extrernal). Lib.t represent a completely resolved library, i.e. where all the dependencies have been resolved. Lib.Compile is used to provide what is necessary to build the library itself. Lib.Meta provides what is necessary to generate the META file for the library. We also have library databases represented as Lib.DB.t. A library database is simply a mapping from names to Lib.t values and and created from a resolve function that looks up a name and return a Lib.Info.t. A Lib.Info.t is the same as a Lib.t except that dependencies are not resolved. A library database can have a parent database that is used to lookup names that are not found in the current database. In practice we have the following hierarchy: 1. For every scope, we have a library database that holds all the libraries of this scope. In this DB, a library can be referred by either it's name or public name 2. the parent of each of these databases is a database that holds all the public libraries of the workspace. In this DB libraries must be referred by their public name 3. the parent of this DB is for installed libraries (1) databases are accessible via Scope.libs (Super_context.find_scope_by_{name,dir} sctx xxx) (2) is accessible via Super_context.public_libs sctx (3) is accessible via Super_context.installed_libs sctx The dependencies of a library are always resolved inside the DB it is part of. When we compute a transitive closure, we check that we don't have two libraries from two different DB with the same name. So for instance linting Base should now supported. Jbuild.Scope_info ----------------- Jbuild.Scope was renamed Jbuild.Scope_info Scope module ------------ This replaces Lib_db. A Scope.t is now just a pair of a Jbuild.Scope_info.t and a Lib.DB.t. Scope.DB.t is an object used to lookup scopes by either name or directory. We no longer have an external scope or special anonymous scope. Instead one should use Super_context.installed_libs or Super_context.public_libs depending on the context. 2018-02-20 11:46:10 +00:00			`-> (Path.t * Scope_info.t * Stanzas.t) list String_map.t Fiber.t`
