* add benchmark
* perf: faster identifier tokenizing
- Mover iterator identifier parsing to the Flow plugin
- If the character is an identifier start, pass it to readWord1
* refactor: raise AwaitNotInAsyncContext when an AwaitExpression will be parsed
* tweak logic
* early exit when errors are before thrown error position
* fix: always return true in assert.throws callback
See https://nodejs.org/api/assert.html#assert_assert_throws_fn_error_message
* update test fixtures
* fix flow error
* fix(babel-parser): avoid state.clone() to clone the whole token store
Fixed the performance issue on large input when turned on option {tokens: true} and typescript plugin which uses quite a few state.clone().
* test(babel-parser): turn on 2 typescript tests with tokens:true
The output.json is generated by old master to make sure no regression.
* fix(babel-parser): avoid duplicated tokens trapped by mainly typescript/flow plugins
* test(babel-parser): update output.json to latest master result
* chore(babel-parser): improve performance by storing tokensLength in state
* Add error recovery support to @babel/parser
* Update @babel/parser tests to always recover from errors
* Update this.raise usage in @babel/parser:
- expression.js
- lval.js
- statement.js
- estree.js
- flow.js
- jsx/index.js
- tokenizer/index.js
* Update @babel/parser fixtures with recovered errors
* Fix tests out of @babel/parser
* Do not use try/catch for control flow
* Update invalid fixtures
* Do not report invalid lhs in toAssignable
* Do not validate function id multiple times
* Dedupe reserved await errors
* Remove duplicate errors about strict reserved bindings
* Remove duplicated error about yield/await inside params
* Don't error twice for methods in object patterns
* Don't report invalid super() twice
* Remove dup error about reserved param for expr arrows
* Remove double escapes in migrated tests
* Dedupe errors about invalid escapes in identifiers
* Remove duplicated error about decorated constructor
* Remove duplicated error about spread in flow class
* Don't throw for invalid super usage
* Don't fail for object decorators with stage 2
* Fix flow inexact type errors
* Fix flow
* Fix errors about escapes in keywords (ref: #10455)
* Update after rebase
* Fix todo
* Remove duplicated error when using += for defaults
* Remove unnecessary throw
* Nit: use ??
* Introduce scope tracking
* Fix tests
* Add new tests
* Remove constructor-super check from transform as it is now in parser
* Correctly handle class properties and class scope
* Fix duplicate name check
* Convert scope identifier storage to array
* Enter a new scope in typescript module blocks
* Add test for duplicate declaration
* Rename error for duplicate exports
* Treat class declarations as lexical declaration
* Update whitelist
* Add tests
* Fix scope tracking for function declarations
* Migrate try-catch duplicate error
* Fix test
* More tests
* One more test
* Make scope a separate class and fix review comments
* Do not allow new.target in top scope arrow function
* Correctly enter new scope for declare module and treat type aliases as lexical declarations
* Tests for typescript scope tracking to not mark type aliases as duplicate
* Fix flow scope tracking
* Remove ident from test names as redundant
* Add test case for var and function
* Improve error messages
* Improve literal regex
* Fix running flow on travis and update flow
- ensure bootstrap is run before running flow as we need some generated files for correctly doing typechecks
- ensure that we only ignore the build directory inside the babel folder as currently we ignore everything because travis checks out into ‘/home/travis/build/’
* Fix all flow errors
Set whether we're in a pipeline in order to determine how to parse the
hash. The error message changes as a result, since the `hash` never
enters the block.
