Support HHVM 4.0

v4.0.0

Update LSP test expectations

Target 3.30, improve NoEmptyStatementLinter

speed up execute_async again

When hh-clilib moved to hsl-experimental IO\ , we lost the async
wrappers around arbitrary resources.

Made a mistake when implementing with builtins.

Back to 5 min build

New linters, and updated dependencies

This release adds 3 new linters:

• a linter suggesting that all classes either be abstract or final
• an autofixing linter banning empty statements
• an autofixing linter converting PHP anonymous functions to lambdas

Additionally, this release:

• updates to hh-clilib v2. This includes moving to hsl-experimental IO abstractions
• Uses hack-codegen v4

Support HHVM/Hack 3.29, add migrations

This release:

• supports and requires HHVM/Hack 3.29
• supports typed user attributes, including 'unused use statement' linter fixes
• marks EditableList::fromItems() as <<__Deprecated>>, in favor of EditableList::createNonEmptyListOrMissing() which is equivalent, but clearer about the behavior
• adds hhast-migrate --is-refinement, replacing is_int() with is int and similar expressions.

This release also includes hhast-migrate --ltgt-to-ne and --hhvm-3.28-to-3.29, replacing <> with !=, which was added in v3.28.7

There have been several changes to the AST in this release; the most significant are:

• classes might not have a name (if the file being parsed is PHP; anonymous classes are not supported in Hack)
• attributes are no longer a unique node type; instead, <<Foo>> is a constructor call to Foo (this is part of the 'typed user attributes' feature)

Improved PHPUnit support, new EditableList factory functions, `<>` to `!=` migration

This release:

• adds bin/hhast-migrate --hhvm-3.28-to-3.29 and --ltgt-to-ne replacing <> with !=; these operators are equivalent. <> will be unsupported in Hack files in 3.29
• adds EditableList::createNonEmptyListOrMissing() and EditableList::createMaybeEmptyList(), as equivalent replacements for EditableList::fromItems() and new EditableList() respectively. fromItems() is likely to be removed in a future release, and the constructor for EditableList is likely to be made private.
• adds support for migrating @expectedException attributes in the PHPUnit-to-HackTest migration

PHPUnit => hacktest + fbexpect improvements

• don't attempt to rewrite non-PHPUnit methods that have the same name as assertions to fbexpect - e.g. $type_spec->assertType('foo') is not a PHPUnit assertion
• handle unqualified references to PHPUnit_Framework_TestCase as a base class
• fix return types for migrated setup/teardown functions (they should be Awaitable<void>)

Improved @dataProvider PHPUnit => HackTest support

This release:

• improves whitespacing handling when migrating @dataProvider doccomment attributes
• supports /** @dataProvider foo */ as a single-line doccomment

Depend on difflib 1.0 instead of 0.2

No functional changes, just a dependency update.

Improved LSP stability, add PHPUnit-to-Hacktest Migration

This release:

• fixes several issues that could lead to partial messages to the IDE, or error/warning messages being mixed into the JSON-RPC stream
• adds bin/hhast-migrate --phpunit-to-hacktest, which migrates test suites from PHPUnit or Hacktest v0.x to HackTest v1.x

LSP stability, improved diff output in CLI

This release:

• prevents the IDE (LSP) integration from crashing when the IDE requests fixes (code actions) for lint errors in files containing parse errors
• provides better colored diff output when ran from the CLI
