From a370908421c4aea1cd8bdb7cf2f617da87f6029d Mon Sep 17 00:00:00 2001 From: Yui Date: Fri, 26 Aug 2016 15:51:10 -0700 Subject: [PATCH] [Transforms] Merge master 08/09 (#10263) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Improve error message * Remove `SupportedExpressionWithTypeArguments` type; just check that the expression of each `ExpressionWithTypeArguments` is an `EntityNameExpression`. * Fix bug * Fix #10083 - allowSyntheticDefaultImports alters getExternalModuleMember (#10096) * Use recursion, and fix error for undefined node * Rename function * Fix lint error * Narrowing type parameter intersects w/narrowed types This makes sure that a union type that includes a type parameter is still usable as the actual type that the type guard narrows to. * Don't allow ".d.ts" extension in an import either. * Add a helper function `getOrUpdateProperty` to prevent unprotected access to Maps. * Limit type guards as assertions to incomplete types in loops * Accept new baselines * Fix linting error * Allow JS multiple declarations of ctor properties When a property is declared in the constructor and on the prototype of an ES6 class, the property's symbol is discarded in favour of the method's symbol. That because the usual use for this pattern is to bind an instance function: `this.m = this.m.bind(this)`. In this case the type you want really is the method's type. * Use {} type facts for unconstrained type params Previously it was using TypeFacts.All. But the constraint of an unconstrained type parameter is actually {}. * Fix newline lint * Test that declares conflicting method first * [Release-2.0] Fix 9662: Visual Studio 2015 with TS2.0 gives incorrect @types path resolution errors (#9867) * Change the shape of the shim layer to support getAutomaticTypeDirectives * Change the key for looking up automatic type-directives * Update baselines from change look-up name of type-directives * Add @currentDirectory into the test * Update baselines * Fix linting error * Address PR: fix spelling mistake * Instead of return path of the type directive names just return type directive names * Remove unused reference files: these tests produce erros so they will not produce these files (#9233) * Add string-literal completion test for jsdoc * Support other (new) literal types in jsdoc * Don't allow properties inherited from Object to be automatically included in TSX attributes * Add new test baseline and delete else in binder The extra `else` caused a ton of test failures! * Fix lint * Port PR #10016 to Master (#10100) * Treat namespaceExportDeclaration as declaration * Update baselines * wip - add tests * Add tests * Show "export namespace" for quick-info * Fix more lint * Try using runtests-parallel for CI (#9970) * Try using runtests-parallel for CI * Put worker count setting into .travis.yml * Reduce worker count to 4 - 8 wasnt much different from 4-6 but had contention issues causing timeouts * Fix lssl task (#9967) * Surface noErrorTruncation option * Stricter check for discriminant properties in type guards * Add tests * Emit more efficient/concise "empty" ES6 ctor When there are property assignments in a the class body of an inheriting class, tsc current emit the following compilation: ```ts class Foo extends Bar { public foo = 1; } ``` ```js class Foo extends Bar { constructor(…args) { super(…args); this.foo = 1; } } ``` This introduces an unneeded local variable and might force a reification of the `arguments` object (or otherwise reify the arguments into an array). This is particularly bad when that output is fed into another transpiler like Babel. In Babel, you get something like this today: ```js var Foo = (function (_Bar) { _inherits(Foo, _Bar); function Foo() { _classCallCheck(this, Foo); for (var _len = arguments.length, args = Array(_len), _key = 0; _key < _len; _key++) { args[_key] = arguments[_key]; } _Bar.call.apply(_Bar, [this].concat(args)); this.foo = 1; } return Foo; })(Bar); ``` This causes a lot of needless work/allocations and some very strange code (`.call.apply` o_0). Admittedly, this is not strictly tsc’s problem; it could have done a deeper analysis of the code and optimized out the extra dance. However, tsc could also have emitted this simpler, more concise and semantically equivalent code in the first place: ```js class Foo extends Bar { constructor() { super(…arguments); this.foo = 1; } } ``` Which compiles into the following in Babel: ```js var Foo = (function (_Bar) { _inherits(Foo, _Bar); function Foo() { _classCallCheck(this, Foo); _Bar.apply(this, arguments); this.foo = 1; } return Foo; })(Bar); ``` Which is well-optimized (today) in most engines and much less confusing to read. As far as I can tell, the proposed compilation has exactly the same semantics as before. Fixes #10175 * Fix instanceof operator narrowing issues * Accept new baselines * Add regression test * Improve naming and documentation from PR * Update comment * Add more tests * Accept new baselines * Reduce worker count to 3 (#10210) Since we saw a starvation issue on one of @sandersn's PRs. * Speed up fourslash tests * Duh * Make baselines faster by not writing out unneeded files * Fix non-strict-compliant test * Fix 10076: Fix Tuple Destructing with "this" (#10208) * Call checkExpression eventhough there is no appropriate type from destructuring of array * Add tests and baselines * use transpileModule * Remove use strict * Improve instanceof for structurally identical types * Introduce isTypeInstanceOf function * Add test * Accept new baselines * Fix loop over array to use for-of instead of for-in * Use correct this in tuple type parameter constraints Instantiate this in tuple types used as type parameter constraints * Add explanatory comment to resolveTupleTypeMembers * Ignore null, undefined, void when checking for discriminant property * Add regression test * Delay tuple type constraint resolution Create a new tuple that stores the this-type. * Always use thisType when generating tuple id * Optimize format of type list id strings used in maps * wip - fix error * Make ReadonlyArray iterable. * Allow OSX to fail while we investigate (#10255) The random test timeouts are an issue. * Fix error from using merging master * avoid using the global name * Fix single-quote lint * Update baselines * Fix linting * Optimize performance of maps * Update API sample * Fix processDiagnosticMessages script * Have travis take shallow clones of the repo (#10275) Just cloning TS on travis takes 23 seconds on linux (68 seconds on mac), hopefully having it do a shallow clone will help. We don't rely on any tagging/artifacts from the travis servers which clone depth could impact, so this shouldn't impact anything other than build speed. * Add folds to travis log (#10269) * Optimize filterType to only call getUnionType if necessary * Add shorthand types declaration for travis-fold (#10293) * Optimize getTypeWithFacts * Filter out nullable and primitive types in isDiscriminantProperty * Fix typo * Add regression tests * Optimize core filter function to only allocate when necessary * Address CR comments + more optimizations * Faster path for creating union types from filterType * Allow an @types direcotry to have a package.json which specifies `"typings": null` to disclude it from automatically included typings. * Lint * Collect timing information for commands running on travis (#10308) * Simplifies performance API * Use 'MapLike' instead of 'Map' in 'preferConstRule.ts'. * narrow from 'any' in most situations instanceof and user-defined typeguards narrow from 'any' unless the narrowed-to type is exactly 'Object' or 'Function'. This is a breaking change. * Update instanceof conformance tests * accept new baselines * add tests * accept new baselines * Use lowercase names for type reference directives * Use proper response codes in web tests * Treat ambient shorthand declarations as explicit uses of the `any` type * Rename 'find' functions * Parallel linting (#10313) * A perilous thing, a parallel lint * Use work queue rather than scheduling work * Dont read files for lint on main thread * Fix style * Fix the style fix (#10344) * Aligned mark names with values used by ts-perf. * Use an enum in checkClassForDuplicateDeclarations to aid readability * Rename to Accessor * Migrated more MapLikes to Maps * Add ES2015 Date constructor signature that accepts another Date (#10353) * Parameters with no assignments implicitly considered const * Add tests * Migrate additional MapLikes to Maps. * Fix 10625: JSX Not validating when index signature is present (#10352) * Check for type of property declaration before using index signature * Add tests and baselines * fix linting error * Adding more comments * Clean up/move some Map helper functions. * Revert some formatting changes. * Improve ReadonlyArray.concat to match Array The Array-based signature was incorrect and also out-of-date. * Fix link to blog * Remove old assertion about when we're allowed to use fileExists * Set isNewIdentifierLocation to true for JavaScript files * Update error message for conflicting type definitions Fixes #10370 * Explain why we lower-case type reference directives * Correctly merge bindThisPropertyAssignment Also simply it considerably after noticing that it's *only* called for Javascript files, so there was a lot of dead code for TS cases that never happened. * Fix comment * Property handle imcomplete control flow types in nested loops * Update due to CR suggestion * Add regression test * Assign and instantiate contextual this type if not present * Fix 10289: correctly generate tsconfig.json with --lib (#10355) * Separate generate tsconfig into its own function and implement init with --lib # Conflicts: # src/compiler/tsc.ts * Add tests and baselines; Update function name Add unittests and baselines Add unittests and baselines for generating tsconfig Move unittest into harness folder Update harness tsconfig.json USe correct function name * Use new MapLike interstead.
