Importing .wasm files is non-standardized therefore deciding to
support current functionality past 1.0 release is risky.
Besides that .wasm import posed many challenges in our codebase
due to complex interactions with TS compiler which spawned
thread for each encountered .wasm import.
This commit removes:
- cli/compilers/wasm.rs
- cli/compilers/wasm_wrap.js
- two integration tests related to .wasm imports
This PR removes op_cache and refactors how Deno interacts with TS compiler.
Ultimate goal is to completely sandbox TS compiler worker; it should operate on
simple request -> response basis. With this commit TS compiler no longer
caches compiled sources as they are generated but rather collects all sources
and sends them back to Rust when compilation is done.
Additionally "Diagnostic" and its children got refactored to use "Deserialize" trait
instead of manually implementing JSON deserialization.
refactor: Parse URLs more sequentially. This makes it easier to change matching behaviour depending on the protocol.
fix: Fail when a host isn't given for certain protocols.
fix: Convert back-slashes info forward-slashes.
Keep in mind Buffer.toString() still exists, but returns [object Object].
Reason for removal of Buffer.toString() was that it implicitly used
TextDecoder with fixed "utf-8" encoding and no way to customize
the encoding.
This change is to prevent needed a separate stat syscall for each file
when using readdir.
For consistency, this PR also modifies std's `WalkEntry` interface to
extend `DirEntry` with an additional `path` field.
This commit removes "combined" interfaces from cli/js/io.ts; in the
like of "ReadCloser", "WriteCloser" in favor of using intersections
of concrete interfaces.
Changed `URL.port` implementation to match [WHATWG
specifications](https://url.spec.whatwg.org/#port-state).
This PR matches the behaviour of other browsers:
1. a `TypeError` must be thrown when passing an URL with an invalid
port to the constructor.
2. When setting an invalid port, using property setter, I haven't found
what should happen in this case, so I mimic **Firefox** & **Node**
behaviour. If an invalid port is set, it will use the previous value.
**Chrome** sets the value to `'0'` if an invalid port is set. I prefer
to keep the previous valid value. (I can use Chrome's behaviour if you
think it's better, it's a simple value change)
```
url.port = '3000'; // valid
url.port = 'deno'; // invalid
assertEquals(url.port, '3000');
```
3. If the port value equals the current protocol default port value,
`port` will be an empty string.
When creating a console instance, one must pass "printFunc" arg
which is used internally by Console to output messages.
Due to numerous refactors there was a single method ("console.clear()")
that used "Deno.stdout" instead of "printFunc".
This commit unifies how "Console" outpus message, by using
"printFunc" in all methods; consequently "Deno.stdout" is no longer
imported in "cli/js/console.ts" making it a standalone module that doesn't
depend on any CLI-specific APIs.
Deno.runTests() interface is not yet good enough to be exposed
publicly with stability guarantees.
This commit removes public API related to testing: Deno.runTests()
and Deno.TestMessage, but keeps them exposed on Deno.internal object
so they can be used with "deno test" subcommand.
Refactors Event and EventTarget so that they better encapsulate their
non-public data as well as are more forward compatible with things like
DOM Nodes.
Moves `dom_types.ts` -> `dom_types.d.ts` which was always the intention,
it was a legacy of when we used to build the types from the code and the
limitations of the compiler. There was a lot of cruft in `dom_types`
which shouldn't have been there, and mis-alignment to the DOM standards.
This generally has been eliminated, though we still have some minor
differences from the DOM (like the removal of some deprecated
methods/properties).
Adds `DOMException`. Strictly it shouldn't inherit from `Error`, but
most browsers provide a stack trace when one is thrown, so the behaviour
in Deno actually better matches the browser.
`Event` still doesn't log to console like it does in the browser. I
wanted to get this raised and that could be an enhancement later on (it
currently doesn't either).
- 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
* Reduce "testing" interfaces
* Use a callback instead of a generator for Deno.runTests()
* Default RunTestsOptions::reportToConsole to true
* Compose TestMessage into a single interface
* Properly track isFile, isSymlink, isDirectory
These don't exhaust all the possibilities, so none of them should be
defined as "neither of the others".
* empty
1. Array elements are now grouped the same as in Node.js
2. Limit to 100 (Node.js default) elements to display in iterable
3. Print each element in new line if excessing max line length (same as in Node.js)
4. Print length of the TypedArray
5. Print information about empty items in Array
This a complex boring PR that shifts around code (primarily) in cli/fs.rs and
cli/ops/fs.rs. The gain of this refactoring is to ease the way for #4188 and
#4017, and also to avoid some future development pain.
Mostly there is no change in functionality. Except:
* squashed bugs where op_utime and op_chown weren't using `resolve_from_cwd`
* eliminated the use of the external `remove_dir_all` crate.
* op_chmod now only queries metadata to verify file/dir exists on Windows (it
will already fail on Unix if it doesn't)
* op_chown now verifies the file/dir's existence on Windows like chmod does.
* 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 PR brings assertOps and assertResources sanitizers to Deno.test() API.
assertOps checks that test doesn't leak async ops, ie. there are no unresolved
promises originating from Deno APIs. Enabled by default, can be disabled using
Deno.TestDefinition.disableOpSanitizer.
assertResources checks that test doesn't leak resources, ie. all resources used
in test are closed. For example; if a file is opened during a test case it must be
explicitly closed before test case finishes. It's most useful for asynchronous
generators. Enabled by default, can be disabled using
Deno.TestDefinition.disableResourceSanitizer.
We've used those sanitizers in internal runtime tests and it proved very useful in
surfacing incorrect tests which resulted in interference between the tests.
All tests have been sanitized.
Closes #4208
Fixes #4101
Previously, we would just provide the raw JSON to the TypeScript
compiler worker, but TypeScript does not transform JSON. This caused
a problem when emitting a bundle, that the JSON would just be "inlined"
into the output, instead of being transformed into a module.
This fixes this problem by providing the compiled JSON to the TypeScript
compiler, so TypeScript just sees JSON as a "normal" TypeScript module.
This PR attempts to fix intermittent errors occurring on Windows for "cli/tests/unit_test_runner.ts." Runner has been reworked to create only single TCP listener instead of one listener per worker.
Additionally worker doesn't close TCP socket - it waits for parent process to close the socket and only then exits.
This commit changes output of default test reporter to resemble output from Rust test runner;
first the name of running test is printed with "...", then after test has run result is printed on the same line.
* Split "Deno.TestEvent.Result" into "TestStart" and "TestEnd";
* changes TestReporter interface to support both events;

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".
* drop server guard before unit test result check
To prevent cascading test failures when js_unit_test http server
guard is dropped before asserting that tests were successful.
This is really a band-aid and doesn't solve underlying issue with
http server.
* Update CLI for unit_test_runner.ts
* Change cli/js/tests/unit_test_runner.ts command line interface to work in 3
modes:
- "one-off" - run tests that match permissions of currently running
process
- "master" - run tests for all possible permission combinations, by
spawning subprocesses running in "worker" mode and communicating via
TCP socket; requires elevated permissions
- "worker" - run tests for set of permissions provided by CLI arg;
requires elevated permissions to setup TCP connection to "master";
after initial setup process drops permissions to given set
* Support filtering of tests by string passed after "--" CLI arg
* Update cli/js/tests/README.md
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").
- moves signal definition from "cli/js/process.ts" to "cli/js/signals.ts"
- removes "cli/js/dispatch.ts"
- removes "cli/js/types.ts"
- moves web specific utilities to "cli/js/web/util.ts"
- moves compiler implementation to "cli/js/compiler/" directory
- moves more APIs to "cli/js/web":
* "console.ts"
* "console_table.ts"
* "performance.ts"
* "timers.ts"
* "workers.ts"
- removes some dead code from "cli/js/"
Listener and UDPConn are AsyncIterables instead of AsyncIterators.
The [Symbol.asyncIterator]()s are defined as generators and the
next() methods are gone.
"Listener/Socket has been closed" errors are now BadResource.
All Deno runtime test files were moved to cli/js/tests/ directory.
It makes a clear distinction that cli/js/tests/ contains code
that is run under Deno runtime as opposed to code in cli/js/ which
is used to create bundle and snapshot with "deno_typescript".
Following JS ops were moved to separate files in cli/js/ops directory:
- io
- process
- worker_host
- web_worker
- plugins
- timers
- signal
- permissions
Following JS ops were moved to separate files in cli/js/ops directory:
- compiler
- dispatch_json
- dispatch_minimal
- errors
- fetch
- fs_events
- os
- random
- repl
- resources
- runtime_compiler
- runtime
- tty
There's a lot of variation in doc comments and internal code about
whether chmod/0o777-style permissions are called `mode` or `perm`. (For
example, mkdir and writeFile choose differently.)
Had proposed earlier to go consistently with `perm`, but on balance devs
prefer to go with `mode`.
There's a lot of variation in doc comments and internal code about
whether the first parameter to file system calls is `path` or `name` or
`filename`. For consistency, have made it always be `path`.
* refactor: preliminary cleanup of Deno.runTests()
* Change time measurement to use new Date() instead of
performance.now(). Because there is no guarantee that tests are
run with "--allow-hr" using new Date() guarantees higher
precision of 1ms instead of 2ms.
* Support String type filter in "skip" and "only".
* Split "exitOnFail" into "exitOnFail" and "failFast".
Former tells if "runTests()" should exit with code 1 on test
failure, while latter tells if "runTests()" should stop
running tests on first failure.
* Use "defer" to wait for unhandled promise rejection - this bit
is funky and doesn't seem right, but for now it's just a rewrite
from using "setTimeout". Intended to be fixed in later commits.
* Remove global "__DENO_TEST_REGISTRY", don't expose list of
registered tests (to be addressed in follow up commits)
* Remove arbitrary slow test threshold; use uniform coloring
instead
- Cleanup "tsCompilerOnMessage" by factoring out separate methods for each
request type:
* "compile"
* "runtimeCompile"
* "runtimeTranspile"
- Simplify control flow of compiler workers by a) no longer calling "close()" in worker runtime after a
single message; b) explicitly shutting down worker from host after a single message

Rewrite "testPerm" helper function used for testing of internal
runtime code. It's been renamed to "unitTest" and provides API that
is extensible in the future by accepting optional "UnitTestOptions"
argument. "test" helper was also removed and replaced by
overloaded version of "unitTest" that takes only function argument.
"UnitTestOptions" currently supports "perms" and "skip"
options, where former works exactly as first argument to "testPerm"
did, while the latter allows to conditionally skip tests.
* add "assertOps" test assertion which makes sure test case
is not "leaking" ops - ie. after test finishes there are no
pending async ops
* apply "assertOps" to all tests in "cli/js/"
* fix numerous tests leaking ops
* document problem with edge case in "clearInterval"
and "clearTimeout" implementation where they
may leak async ops
* move "cli/js/worker_test.ts" to "cli/tests/worker_test.ts" and
run as integration test; workers leak ops because of missing
"terminate" implementation
Fixes #4602
We turned off `allowJs` by default, to keep the compiler from grabbing
a bunch of files that it wouldn't actually do anything useful with. On
the other hand, this caused problems with bundles, where the compiler
needs to gather all the dependencies, including JavaScript ones. This
fixes this so that when we are bundling, we analyse JavaScript imports
in the compiler.
* Rename MkdirOption interface to MkdirOptions
It was hard to remember which Options interfaces were spelled in the
singular and which in the plural (and anyway this one contained two
options).
Also added MkdirOptions to cli/js/deno.ts. All the analogous interfaces
were exported there.
* Rename RemoveOption interface to RemoveOptions
This was the last remaining Option interface spelled in the singular.
Easier to remember if they're all Option**s**; plus we may want to add extra
options here later.
Previously, bundles always utilised top level await, even if the bundled
modules didn't require top level await. Now, analysis of the bundle is
done and if none of the bundled modules are asynchronously executed,
then the bundle as a whole will be synchronously executed.
Fixes #4055
Fixes #4123
This PR fixes an issue where we recursively analysed imports on plain JS files
in the compiler irrespective of "checkJs" being true. This caused problems
where when analysing the imports of those files, we would mistake some
import like structures (AMD/CommonJS) as dependencies and try to resolve
the "modules" even though the compiler would not actually look at those files.
Fixes #4031
When a bundle contains a single module, we were incorrectly determining
the module name, resulting in a non-functional bundle. This PR corrects
that determination.
Moves to using a minimal System loader for bundles generated by Deno.
TypeScript in 3.8 will be able to output TLA for modules, and the loader
is written to take advantage of that as soon as we update Deno to TS
3.8.
System also allows us to support `import.meta` and provide more ESM
aligned assignment of exports, as well as there is better handling of
circular imports.
The loader is also very terse versus to try to save overhead.
Also, fixed an issue where abstract classes were not being re-exported.
