From 8214b686cea3f6ad57d7da49a44d33185fdeb098 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bartek=20Iwa=C5=84czuk?= Date: Thu, 18 Jul 2019 00:15:30 +0200 Subject: [PATCH] Refactor DenoDir (#2636) * rename `ModuleMetaData` to `SourceFile` and remove TS specific functionality * add `TsCompiler` struct encapsulating processing of TypeScript files * move `SourceMapGetter` trait implementation to `//cli/compiler.rs` * add low-level `DiskCache` API for general purpose caches and use it in `DenoDir` and `TsCompiler` for filesystem access * don't use hash-like filenames for compiled modules, instead use metadata file for storing compilation hash * add `SourceFileCache` for in-process caching of loaded files for fast subsequent access * define `SourceFileFetcher` trait encapsulating loading of local and remote files and implement it for `DenoDir` * define `use_cache` and `no_fetch` flags on `DenoDir` instead of using in fetch methods --- cli/compiler.rs | 837 +++++--- cli/deno_dir.rs | 1702 +++++++---------- cli/disk_cache.rs | 150 ++ cli/flags.rs | 8 +- cli/fs.rs | 29 + cli/main.rs | 110 +- cli/msg.fbs | 8 +- cli/ops.rs | 91 +- cli/state.rs | 133 +- cli/worker.rs | 2 +- js/compiler.ts | 47 +- tests/024_import_no_ext_with_headers.test | 5 +- tests/error_004_missing_module.ts.out | 2 +- tests/error_005_missing_dynamic_import.ts.out | 2 +- tests/error_006_import_ext_failure.ts.out | 2 +- tests/error_011_bad_module_specifier.ts.out | 2 +- ...or_012_bad_dynamic_import_specifier.ts.out | 2 +- tools/deno_dir_test.py | 18 +- tools/integration_tests.py | 11 +- 19 files changed, 1707 insertions(+), 1454 deletions(-) create mode 100644 cli/disk_cache.rs diff --git a/cli/compiler.rs b/cli/compiler.rs index 2a6bd1adef..6e1399b445 100644 --- a/cli/compiler.rs +++ b/cli/compiler.rs @@ -1,57 +1,80 @@ // Copyright 2018-2019 the Deno authors.
