All benchmarks are done in Rust and can be invoked with
`cargo bench`.
Currently this has it's own "harness" that behaves like
`./tools/benchmark.py` did.
Because of this tests inside `cli/bench` are currently not run.
This should be switched to the language provided harness
once the `#[bench]` attribute has been stabilized.
This ensures that all spaces are set to be "+" in the string rather than
just the first and brings deno into line with how browsers handle spaces
in URLSearchParams, see #7001.
- Fix protocol regex.
- Truncate repeated leading slashes in file paths.
- Make drive letter support platform-independent.
- Drop the hostname if a drive letter is parsed.
- Fix drive letter normalization and basing.
- Allow basing over the host.
- Fix same-protocol basing.
- Remove Windows UNC path support.
- Reverts #6418. This is non-standard. Wouldn't be too much of a problem but it
makes other parts of the spec hard to realize.
This PR is intentionally ugly. It duplicates all of the code in cli/js2/ into
cli/tsc/ ... because it's very important that we all understand that this code
is unnecessarily duplicated in our binary. I hope this ugliness provides the
motivation to clean it up.
The typescript git submodule is removed, because it's a very large repo and
contains all sorts of stuff we don't need. Instead the necessary files are
copied directly into the deno repo. Hence +200k lines.

Fixes #6812
This commit adds a fallback mechanism for absent compiled source file.
Because imported type declaration files are not emitted by TS compiler
and their imports are not elided users often hit "No such file or directory"
error. With this commit in such situation an empty source file will be
provided to V8 with a warning to the user suggesting using "import type"/
"export type" syntax instead.
This commit adds a "--no-check" option to following subcommands:
- "deno cache"
- "deno info"
- "deno run"
- "deno test"
The "--no-check" options allows to skip type checking step and instead
directly transpiles TS sources to JS sources.
This solution uses `ts.transpileModule()` API and is just an interim
solution before implementing it fully in Rust.
Currently, the documentation makes it sound like the test subcommand's filter
flag could accept some kind of pattern matching value like a glob or a regex,
although the function "createFilterFn" accepts a regex as an argument, there's
no way to pass an actual regex value from the CLI.
This commit makes it possible to pass a string that could be cast as regex
when string matches "^/.*/$".
With this change, a user can use the filter flag as follow:
deno test --filter "/test-.+/"
Also tested that `\` get escaped properly, on MacOS at least, and this is
also a valid flag:
deno test --filter "/test-\d+/"
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).
The following used to fail in Deno despite working in the browser:
```javascript
new Request('http://localhost/', {method: 'POST', body: new URLSearchParams({hello: 'world'})}).text().then(console.log)
```
* 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 provides a "system_loader_es5.js" bundle loader which will be added
to the bundle when the target is < ES2017, which is the minimum target syntax
required for "system_loader.js".
Supports #5913 (via Deno.bundle()) with a couple caveats:
* Allowing "deno bundle" to take a different target is not supported, as we
specifically ignore "target" when passed in a TypeScript config file. This is
because deno bundle is really intended to generate bundles that work in Deno.
It is an unintentional side effect that some bundles are loadable in browsers.
* While a target of "es3" will be accepted, the module loader will still only be
compatible with ES5 or later. Realistically no one should be expecting bundles
generated by Deno to be used on IE8 and prior, and there is just too much
"baggage" to support that at this point.
This is a minor variation of 75bb9d, which exposed some sort of internal V8 bug.

The tests for testing that `Deno.truncateSync` and `Deno.truncate`
require write permissions seem to not call the functions they are
testing *at all* and are calling `Deno.mkdir` and `Deno.mkdirSync`
instead.
This commit replaces those calls with calls to `Deno.truncateSync`
and `Deno.truncate` respectively.
Currently WebAssembly runtime errors don't propagate up to the user as
they use urls to denote where the error occurred which get caught by the source-map
pipeline which doesn't support the wasm scheme.
This commit:
* added default file globs so "deno lint" can be run
without arguments (just like "deno fmt")
* added test for globs in "deno lint"
* upgrade "deno_lint" crate to v0.1.9
