- Improves op performance.
- Handle op-metadata (errors, promise IDs) explicitly in the op-layer vs
per op-encoding (aka: out-of-payload).
- Remove shared queue & custom "asyncHandlers", all async values are
returned in batches via js_recv_cb.
- The op-layer should be thought of as simple function calls with little
indirection or translation besides the conceptually straightforward
serde_v8 bijections.
- Preserve concepts of json/bin/min as semantic groups of their
inputs/outputs instead of their op-encoding strategy, preserving these
groups will also facilitate partial transitions over to v8 Fast API for the
"min" and "bin" groups
This commit rewrites scripts in "tools/" directory
to use Deno instead of Python. In return it allows
to remove huge number of Python packages in "third_party/".
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 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 "--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.
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 PR removes the hack in CLI that allows to run scripts with shorthand: deno script.ts.
Removing this functionality because it hacks around short-comings of clap our CLI parser. We agree that this shorthand syntax is desirable, but it needs to be rethinked and reimplemented. For 1.0 we should go with conservative approach that is correct.
- Removes the __fetch namespace from `deno types`
- Response.redirect should be a static.
- Response.body should not be AsyncIterable.
- Disables the deno_proxy benchmark
- Makes std/examples/curl.ts buffer the body before printing to stdout
* Remove DENO_BUILD_MODE and DENO_BUILD_PATH
Also remove outdated docs related to ninja/gn.
* fix
* remove parameter to build_mode()
* remove arg parsing from benchmark.py
* add tests for "Deno.core.encode" and "Deno.core.decode" for empty inputs
* use "Deno.core.encode" in "TextEncoder"
* use "Deno.core.decode" in "TextDecoder"
* remove "core_decode" and "core_encode" benchmarks
This commits add two new methods to "Deno.core" namespace: "encode" and "decode".
Those methods are bound in Rust to provide a) fast b) generally available of encoding and decoding UTF-8 strings.
Both methods are now used in "cli/js/dispatch_json.ts".
Rewrites "cli/js/unit_test_runner.ts" to communicate with spawned subprocesses
using TCP socket.
* Rewrite "Deno.runTests()" by factoring out testing logic to private "TestApi"
class. "TestApi" implements "AsyncIterator" that yields "TestEvent"s,
which is an interface for different types of event occuring during running
tests.
* Add "reporter" argument to "Deno.runTests()" to allow users to provide custom
reporting mechanism for tests. It's represented by "TestReporter" interface,
that implements hook functions for each type of "TestEvent". If "reporter"
is not provided then default console reporting is used (via
"ConsoleReporter").
* Change how "unit_test_runner" communicates with spawned suprocesses. Instead
of parsing text data from child's stdout, a TCP socket is created and used
for communication. "unit_test_runner" can run in either "master" or "worker"
mode. Former is responsible for test discovery and establishing needed
permission combinations; while latter (that is spawned by "master") executes
tests that match given permission set.
* Use "SocketReporter" that implements "TestReporter" interface to send output
of tests to "master" process. Data is sent as stringified JSON and then
parsed by "master" as structured data. "master" applies it's own reporting
logic to output tests to console (by reusing default "ConsoleReporter").
This change simplifies how we execute V8. Previously V8 Isolates jumped
around threads every time they were woken up. This was overly complex and
potentially hurting performance in a myriad ways. Now isolates run on
their own dedicated thread and never move.
- blocking_json spawns a thread and does not use a thread pool
- op_host_poll_worker and op_host_resume_worker are non-operational
- removes Worker::get_message and Worker::post_message
- ThreadSafeState::workers table contains WorkerChannel entries instead
of actual Worker instances.
- MainWorker and CompilerWorker are no longer Futures.
- The multi-threaded version of deno_core_http_bench was removed.
- AyncOps no longer need to be Send + Sync
This PR is very large and several tests were disabled to speed
integration:
- installer_test_local_module_run
- installer_test_remote_module_run
- _015_duplicate_parallel_import
- _026_workers
This flag was added to evaluate performance relative to tokio's threaded
runtime. Although it's faster in the HTTP benchmark, it's clear the runtime
is not the only perf problem.
Removing this flag will simplify further refactors, in particular
adopting the #[tokio::main] macro. This will be done in a follow up.
Ultimately we expect to move to the current thread runtime with Isolates
pinned to specific threads, but that will be a much larger refactor. The
--current-thread just complicates that effort.
- Bundles are fully standalone. They now include the shared loader with
`deno_typescript`.
- Refactor of the loader in `deno_typescript` to perform module
instantiation in a more
- Change of behaviour when an output file is not specified on the CLI.
Previously a default name was determined and the bundle written to that
file, now the bundle will be sent to `stdout`.
- Refactors in the TypeScript compiler to be able to support the concept
of a request type. This provides a cleaner abstraction and makes it
easier to support things like single module transpiles to the userland.
- Remove a "dangerous" circular dependency between `os.ts` and `deno.ts`,
and define `pid` and `noColor` in a better way.
- Don't bind early to `console` in `repl.ts`.
- Add an integration test for generating a bundle.
The yarn.lock file is moved from //third_party to the root of
the main repository. This is where other package metadata
files (e.g. Cargo.lock and package.json) are also located.
- Fixes cargo publish on deno_typescript, deno_cli_snapshots, and
deno_cli.
- Combines cli_snapshots and js into one directory.
- Extracts TS version at compile time rather than runtime
- Bumps version awkwardly - it was necessary to test end-to-end
publishing. Sorry.
- Adds git submodule deno_typescript/typescript
* Remove reference to removed dir 'third_party/rust_crates'.
* Remove reference to unused environment variable 'DENO_NINJA_PATH'.
* Remove helper functions 'root()' and 'tp()'.
* Move definition of 'third_party_path' to build.py.
* Move definition of 'gn_exe()' to setup.py.
* Move 'download_sccache()' and 'download_hyperfine()' from prebuilt.py
to third_party.py, and delete prebuilt.py.
* Add helper function 'get_platform_dir_name()' to locate the
platform-specific 'v8/buildtools/<platform>' and
'prebuilt/<platform>' directories.
* Add helper function 'get_prebuilt_tool_path()' that returns the full
path to a platform-specific executable in //prebuilt.
* Cosmetic improvements.
//build was updated and our patch rebased:
https://github.com/denoland/chromium_build/tree/20190910_win_clang_depfile
V8 has removed the binaries third_party/v8/buildtools/*/gn.sha1 and started
using CIPD. In this patch, I've hacked in the original .sha1 files and continue to
use download_from_google_storage instead of the new CIPD. This will be fixed
in later work.
Instead of using core/snapshot_creator.rs, instead two crates are
introduced which allow building the snapshot during build.rs.
Rollup is removed and replaced with our own bundler. This removes
the Node build dependency. Modules in //js now use Deno-style imports
with file extensions, rather than Node style extensionless imports.
This improves incremental build time when changes are made to //js files
by about 40 seconds.
* 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
Don't mix every http request in with the tests output.
Don't print that the file servers are starting unless
-vv flag is passed.
Capture the output of run with run_output which returns
stdout, stderr and exit_code. Test against this rather
than relying on sys.exit.
* use subclass of unittest.TestCase for all test cases
* allow to run single test file (eg. python tools/integration_tests.py)
* test filtering (via --pattern/-p CLI flag)
* use common CLI parser for all tests:
usage: test.py [-h] [--failfast] [--verbose] [--executable EXECUTABLE]
[--release] [--pattern PATTERN] [--build-dir BUILD_DIR]
optional arguments:
-h, --help show this help message and exit
--failfast, -f Stop on first failure
--verbose, -v Verbose output
--executable EXECUTABLE
Use external executable of Deno
--release Test against release executable
--pattern PATTERN, -p PATTERN
Run tests that match provided pattern
--build-dir BUILD_DIR
Deno build directory
* respect NO_COLOR variable
Move every test to a method on DenoTestCase.
test.py is a single TestSuite of every TestCase.
Add a Spawn context manager for http_server,
this is explicitly used where it's needed.
Each python test file can now be run independently
without needing to manually run http_server.
Add --help and consistent flags using argparse for
each python test, including --failfast.
Use ColorTextTestRunner so that '... ok' is green.
This is to ensure a more fair test. Also we were already downloading
from the internet since we changed the URL to use std@v0.5.0. This
change exposes an OOM bug, which is then fixed in the upcoming compiler
refactor by changing checkJs compiler option to false.
The following tests were commented out in order to get this to go green :
- bodyMultipartFormData
- bodyURLEncodedFormData
- fetchRequestInitStringBody
- netConcurrentAccept
- netListenAsyncIterator
They were silently broken in 780e72 due to flag reordering. This commit
also includes a new assert that would avoid that kind of failure in the
future.
Fixes some sed errors introduced in c43cfe.
Unfortunately moving libdeno required splitting build.rs into two parts,
one for cli and one for core.
I've also removed the arm64 build - it's complicating things at this
re-org and we're not even testing it. I need to swing back to it and get
tools/test.py running for it.
