This commit adds incremental compilation capabilities to internal TS compiler.
Instead of using "ts.createProgram()" API for compilation step (during deno
startup), "ts.createIncrementalProgram()" API is used instead.
Thanks to TS' ".tsbuildinfo" file that already stores all necessary metadata
for compilation I was able to remove our own invention that is ".graph" file.
".tsbuildinfo" file is stored alongside compiled source and is used to
cache-bust outdated dependencies, facilitated by the "version" field.
The value for "version" field is computed in Rust during loading of module
graph and is basically a hash of the file contents.
Please keep in mind that incremental compilation is only used for initial
compilation (or dynamic imports compilation) - bundling and runtime compiler
APIs haven't been changed at all.
Due to problems with source map I changed compilation settings to inline
source map (inlineSourceMap instead of sourceMap).
* refactor "compile" and "runtimeCompile" in "compiler.ts" and factor out
separate methods for "compile" and "bundle" operations
* remove noisy debug output from "compiler.ts"
* provide "Serialize" implementations for enums in "msg.rs"
* rename "analyze_dependencies_and_references" to "pre_process_file" and
move it to "tsc.rs"
* refactor ModuleGraph to use more concrete types and properly annotate
locations where errors occur
* remove dead code from "file_fetcher.rs" - "SourceFile.types_url" is no
longer needed, as type reference parsing is done in "ModuleGraph"
* remove unneeded field "source_path" from ".meta" files stored for
compiled source file (towards #6080)
This commit fixes several regressions in TS compiler:
* double compilation of same module during same process run
* compilation of JavaScript entry point with non-JS imports
* unexpected skip of emit during compilation
Additional checks were added to ensure "allowJs" setting is
used in TS compiler if JavaScript has non-JS dependencies.
This PR addresses many problems with module graph loading
introduced in #5029, as well as many long standing issues.
"ModuleGraphLoader" has been wired to "ModuleLoader" implemented
on "State" - that means that dependency analysis and fetching is done
before spinning up TS compiler worker.
Basic dependency tracking for TS compilation has been implemented.
Errors caused by import statements are now annotated with import
location.

This commit changes how error occurring in SWC are handled.
Changed lexer settings to properly handle TS decorators.
Changed output of SWC error to annotate with position in file.
This commit fixes a bug introduced in #5029 that caused bad
handling of redirects during module analysis.
Also ensured that duplicate modules are not downloaded.
This commit disabled flaky test in cli/module_graph.rs.
The test uses 019_media_types.ts which was known to be flaky
for some time. Test should be reenabled once test HTTP server
is rewritten to Rust.
This commit completely overhauls how module analysis is
performed in TS compiler by moving the logic to Rust.
In the current setup module analysis is performed using
"ts.preProcessFile" API in a special TS compiler worker
running on a separate thread.
"ts.preProcessFile" allowed us to build a lot of functionality
in CLI including X-TypeScript-Types header support
and @deno-types directive support. Unfortunately at the
same time complexity of the ops required to perform
supporting tasks exploded and caused some hidden
permission escapes.
This PR introduces "ModuleGraphLoader" which can parse
source and load recursively all dependent source files; as
well as declaration files. All dependencies used in TS
compiler and now fetched and collected upfront in Rust
before spinning up TS compiler.
To achieve feature parity with existing APIs this commit
includes a lot of changes:
* add "ModuleGraphLoader"
- can fetch local and remote sources
- parses source code using SWC and extracts imports, exports, file references, special
headers
- this struct inherited all of the hidden complexity and cruft from TS version and requires
several follow up PRs
* rewrite cli/tsc.rs to perform module analysis upfront and send all required source code to
TS worker in one message
* remove op_resolve_modules and op_fetch_source_files from cli/ops/compiler.rs
* run TS worker on the same thread
