485,391,901 | pytorch | Error in python3: double free or corruption (fasttop) | Training crashes after a variable number of iterations, after a variable amount of time, and on a variable training example. I checked torch.cuda.memory_allocated() and it is only using .15GB at crash time, not close to running out of memory. I have also made sure that I am not running out of CPU memory.

## Search Terms
- tsconfig / jsconfig
- tsserver
## Problem
Some common project templates (such as angular) generate config file with names such as `tsconfig.dev.json`. The TS Server used by VS Code will not load this project because the file is not named `tsconfig.json`. We only load project files exactly named `tsconfig.json`
## Feature Request
Allow users to configure a specific set one or more project config files that the TS Server should load, such as `/Users/matb/project/test/tsconfig.dev.json`. This could either be configured using a server command line flag or using the `configure` request in TS
## How do we handle additional projects?
If specific project files have been configured, one proposal is that we only load those projects (and never fall back to loading additional projects). Using this approach, when a user opens a new file:
- If that file is part of one of the configured projects, then open it inside the project
- Otherwise load the file in the inferred/global project
As an alternative to this to better support multi-root workspaces in VS Code, we could instead only fall back to loading an additional project if that project is not under the roots of any of the configured projects. For example, if I configured `/Users/matb/project/test/tsconfig.dev.json` as the project to load, we should never load additional projects under: `/Users/matb/project/test/**` but could load ones from under `/Users/matb/project/other/**` | Suggestion,VS Code Tracked,Rescheduled | medium | Critical |

485,516,037 | go | encoding/json: unmarshal option to treat omitted fields as null | Json objects have two types of null-like fields, either a null value for `foo` such as `{"foo":null}`, or an omitted `foo` field such as `{}`. When unmarshalling into a Golang struct, the field can't really be absent, but I can choose whether the field's type is nullable or not(*1). I don't want to preserve the distinction between json absent and null (one null-type is plenty), so I'd like the option to treat the absent field as if it were `null`, and map both null-like json types into the same Golang behaviour.
(*1) See #33835 for proper `null` unmarshalling support, where `null` into a non-nullable type returns an error, and user-defined types determine whether they can unmarshal `null` or not. This issue makes most sense in combination with that. The current behaviour is to treat both absent and `null` like absent when unmarshalling, and in combination with #33835, the (opt-in) behaviour I'm proposing is to treat both absent and `null` like `null` instead.
The behaviour that I want to avoid is having the Golang field skipped over during unmarshalling when the json field is absent. If my Golang field is optional / some nullable type, it doesn't make a huge difference - the field will be skipped, stay at its zero value, which I can define as the same value I'd get unmarshalling `null` into it. The issue is when I have a non-nullable field - I've gone to the effort of saying my input has a defined structure with a defined non-nullable type, I want the unmarshaller to return an error if the input did not contain the structure I said it should. My proposal would return an error in this case, by treating the absent as `null`, then unmarshalling `null` into the non-nullable golang type, and in combination with (*1) that would return an error.
The implementation I prefer is an opt-in `json.Decoder` flag along the lines of `OmittedAsNull()`, so I can set it once for my whole project. I'm less interested in an `omittedasnull` struct tag, because I'd end up writing it on every struct field I define.
Either way the code would be the same when they're used: after parsing an object into a struct, determine which struct fields were not visited, and unmarshal `null` into them.

485,640,115 | rust | Better error message for 'is private' | ```
mod foo {
use bar::A;
mod bar {
pub struct A {}
}
}
use foo::A;
fn main() {}
```
Produces the error:
```
error[E0603]: struct `A` is private
--> src/main.rs:9:10
|
9 | use foo::A;

```
[playground link](https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=3d060124806bfade3ad4432abfef86b9)
It would be great if the error message said _why_ the pub struct 'A' is private.
For example something like this:
```
error[E0603]: struct `A` is private because it is not exported by module foo
```
This would remove the head scratching time as one looks at the definition of the struct and sees the `pub` visibility modifier. | C-enhancement,A-diagnostics,A-visibility,T-compiler,A-suggestion-diagnostics | low | Critical |

### Expected Behavior
can get focus on input box and enter text normally
### Actual Behavior
When called the alert('xxx') and close the message box,
the input-box on the page has lost focus and can't enter any text into it.
Then, I focus to any other window, and focus back to my window(the page), the focus is back.
### To Reproduce
put <input > in the page, call window.alert('xxx').

Entering the version is time consuming. Also you have to check twice if it is the right version. Very often the command `nvm list` is a precondition for using the command to select the version.
My enhancement would be to make the `nvm list` command more interactive. So that we can just select the right version by pressing the up and down arrows.

485,720,428 | flutter | Multiple pinned widgets will cause the overlapsContent in the delegate of the SilverrPersistentHeader to return true. | Multiple pinned widgets(the `pinned` are set to `true`) will cause the `overlapsContent` in the `delegate` of the `SilverrPersistentHeader` to return `true`, as shown in the interface:
When sliding the `SliverFixedExtentList` under the `SliverPersistentHeader`, before the height of the `SliverPersistentHeader` starts to get smaller, a part of the `SliverFixedExtentList`(about 80 pixels) will be retracted to the bottom of the `SliverPersistentHeader` .
## Steps to Reproduce
1.
```dart
@override
Widget build(BuildContext context) {
return Scaffold(
body: CustomScrollView(
slivers: <Widget>[
SliverAppBar(
pinned: true,
expandedHeight: 180,

),
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate((BuildContext context, int index) {
return Text('list item $index');
}, childCount: 10),
),
],
physics: BouncingScrollPhysics(),
controller: _scrollController,
),
);
}
```
2.
```dart
class _SliverHeaderDelegate extends SliverPersistentHeaderDelegate {
double _maxExtent, _minExtent;
_SliverHeaderDelegate(this._maxExtent, this._minExtent);
@override
Widget build(BuildContext context, double shrinkOffset, bool overlapsContent) {
return SizedBox.expand(
child: Container(
color: overlapsContent ? Colors.red : Colors.lightBlue,
child: Center(child: Text("$shrinkOffset")),
),
);
}
@override
double get maxExtent => _maxExtent;
@override
double get minExtent => _minExtent;
@override
bool shouldRebuild(SliverPersistentHeaderDelegate oldDelegate) {
return oldDelegate != this || oldDelegate?.maxExtent != this.maxExtent || oldDelegate?.minExtent != this.minExtent;
}
}

I have asked the question on Gitter and most of the users believe it's a bug and I have search for existing issues and didn't found any.
## Issue
Let's start with the code. [Playground link](https://www.typescriptlang.org/play/index.html#code/CYUwxgNghgTiAEkoGdnwGIHtPwN4CgBIABwFcAjCASzHjmAAoBKALngBcALK5IsymnRCN2IAB7s2ydjCoA7AOat402YvwBffPlBI4iaKngAhWHj4VqteszZceFgdeENREqTPlKPahZu1gmHLS8ABm2GxYOAA+JmYAvPByIADuGNjM+IHB7PBQ8InhmAB0NgDkbuxlTEA)
```ts
declare class Foo {
public red(): this
public red(text: string): string
}
declare class Bar {
public red(): this
public red(text: string): string
}
const foo: Foo | Bar = new Foo()
const a = foo.red('text')
```
In the above code, I expect the variable `a` to be a string. However, it is `string | Bar`.
Now, things get even weird when I replace `string` with `object` in the return types of `red` method.
```ts
declare class Foo {
public red(): this
public red(text: string): object
}
declare class Bar {
public red(): this
public red(text: string): object
}
const foo: Foo | Bar = new Foo()
const a = foo.red('text')
```
Now suddenly, `a` is an `object` (which is correct) | Bug | low | Critical |

`listenToScriptOutputLine()` repeatedly opens a file and reads available lines from a named pipe using `readAsLines()`. Internally, `readAsLines()` opens a `RandomAccessFile`, which consumes a file descriptor. When the pipe is temporarily exhausted, `readAsLines()` issues an asynchronous operation to close the file, but the `Future` returned by `readAsLines()` is completed before the asynchronous `close()` can complete. This is a transient file descriptor leak, for which we have observed crashes in the wild:

The existing code in the Flutter tool can be made to work with a fix in `readAsLines()` to make the `Future` it returns only when the asynchronous close completes. However, this code in the Flutter tool should be made more idiomatic by instead treating the named pipe as a `Stream`. | team,c: crash,platform-ios,tool,P3,team-ios,triaged-ios | low | Critical |

485,974,149 | material-ui | [Lab] Improve accessibility of ToggleButton and ToggleButtonGroup | ## Summary π‘
I'm opening this issue as a continuation of discussion that was initiated in #17187.
ToggleButton and ToggleButtonGroup elements should be marked with appropriate role and aria attributes depending on their usage.
Copying part of my comment from #17187, this is what I envision:
- **ToggleButtonGroup exclusive selection**:
- ToggleButtonGroup has `role="group"` and `aria-label="......"` attributes
- ToggleButtons have `role="menuitemradio"`, `aria-checked="true/false"`, and maybe aria-label attributes.
- **ToggleButtonGroup multiple selection**:
- ToggleButtonGroup has `role="group"` and `aria-label="......"` attributes
- ToggleButtons have `role="menuitemcheckbox"`, `aria-checked="true/false"`, and, if necessary, `aria-label="...."` attributes
- **Standalone ToggleButton**:
- ToggleButton has `role="button"`, `aria-pressed="true/false"`, and maybe aria-label.
It would be great if somebody with more experience in accessibility could chime in.
## Examples π
A reference example: http://jongund.github.io/oaa-examples/examples/menubar/menubar-2/menubar-2.html (Jon Gunderson does a lot of work on W3C Aria Practices. I'd consider him a reliable source.)
FWIW, Angular Material's example uses `role="group"` on their ToggleButtonGroup and `role="button"` on their ToggleButtons. Their docs only have an example of exclusive selection though. I haven't bothered seeing what they do in a multiple selection scenario, though they describe it: https://material.angular.io/components/button-toggle/overview#accessibility
https://www.w3.org/WAI/PF/aria/roles
## Motivation π¦
Improve accessibility.

486,004,188 | pytorch | JIT leaks memory when I change the max sequence length | ## π Bug
When I send a series of inputs of a different max_length to jit, it allocates ~200 megabytes and never frees it.
Valgrind does not catch the leak, but it's there.
[standalone_jit_memory_leak.zip](https://github.com/pytorch/pytorch/files/3547845/standalone_jit_memory_leak.zip)
This is CPU forward pass only. No training. No GPU.
## To Reproduce
Steps to reproduce the behavior:
The attached project feeds randomly generated data into the JIT.
The sequence length is different each time.
1. Use a linux machine or edit the memory_use code to work with your OS
1. unzip the package (torch v1.2.0 must be accessible to CMake)
1. compile and run main.cpp through cmake
1. observe how memory usage increases rapidly with each iteration
0: 0.75GB
1: 1GB
2: 1.2GB
3: 1.6GB
## Expected behavior
Memory use should remain relatively constant
0: 0.75GB
1: 0.75GB
2: 0,75GB
3: 0,75GB

486,023,593 | react | Confusing error when passing non-function to useMemo |
[Example](https://codesandbox.io/s/boring-albattani-grhhp).
When passing something like an object to `useMemo` the error isn't very helpful.
```
TypeError: nextCreate is not a function
at mountMemo (https://grhhp.csb.app/node_modules/react-dom/cjs/react-dom.development.js:13459:19)
...
```
Most developers wont know what `nextCreate` is, and passing an object to `useMemo` doesn't seem _obviously_ wrong at first. We could add a `typeof` check that throws a better error, but maybe that's too much overhead? At the very least we could add a DEV warning with more helpful guidance. | Component: Hooks,Partner | low | Critical |

### What did you do?
I wrote a program that copies media files from one location to another and sets the ctime and mtime to the original file timestamp. The program copies a file and changes the date using `io.Copy(destFile, srcFile)` then calls `os.Chtimes(dest, t.AccessTime(), t.ModTime())` to set the dates.
### What did you expect to see?
The dates to change to the dates provided... or an error at least. This silently fails.
### What did you see instead?
It works appropriately in most cases, but when copying from a windows machine to a Linux SMB server the destination date is always set to `now` instead of changing to the src date.
It works from Windows to Windows and from Mac to Mac. I haven't tried other combinations yet.

486,026,155 | neovim | paste: handle "dangling paste" (missing stop-paste code) | Since https://github.com/neovim/neovim/pull/4448 , paste is handled now by the `vim.paste()` handler (which is invoked by the UI via `nvim_paste()`).
There is a potential issue where the TUI could get stuck in paste-mode if the host terminal fails to send a stop-paste sequence (`<Esc>[201~`). In this state, the user could recover by RPC:
nvim_paste([''], 3)
Nvim GUIs using `nvim_paste` do _not_ need such workarounds because they use an out-of-band channel (as opposed to the TUI where user input + paste are in-band).
Vim [fixed a similar issue](https://github.com/vim/vim/commit/fdd7155fab3447b38280035c66178330f8f041e7) with its bracketed-paste implementation, but:
- the "infinite loop" problem does not apply because Nvim doesn't actively loop
- CTRL-C would not interrupt the paste in Nvim, so a "dangling paste" is less likely. (Could be caused by network failure instead.)
- But CTRL-C would be useful for _recovering from_ this "stuck in paste" state.
- Related: https://github.com/neovim/neovim/issues/13031#issuecomment-1138454495
# Plan
1. TUI needs to check `nvim_paste()` result (e.g. revert https://github.com/neovim/neovim/pull/10878/commits/2c605d1f22a243bc34b680f69c7c8cfe01b80887 )
2. `vim.paste()` Lua handler could track some state to decide if a paste is "stuck". E.g. if the paste stream is very "slow", and CTRL-C is seen ~twice in a row, we can guess that (1) the paste was exhausted and (2) the user is trying to cancel the operation, thus `false` should be returned. | enhancement,clipboard,tui,input,has:plan | low | Critical |

### What did you do?
Consider the following program that sets
- `IdleConnTimeout: 1 * time.Nanosecond`
- `MaxIdleConns: 1`
and makes GET https://example.com calls:
```go
package main
import (
"net/http"
"time"
"log"
"net"
)
func main() {
c := &http.Client{
Transport: &http.Transport{
IdleConnTimeout: 1 * time.Nanosecond,
MaxIdleConns: 1,
DialContext: (&net.Dialer{
KeepAlive: -1,
}).DialContext,
},
}
for {
req, _ := http.NewRequest(http.MethodGet, "https://www.example.com", nil)
resp, err := c.Do(req)
if err != nil {
log.Fatal(err)
}
resp.Body.Close()
log.Printf("request complete")
time.Sleep(100*time.Millisecond)
}
}
```
### What did you expect to see?
Client uses tls connection fully. Puts it back, then the timeout starts counting.
### What did you see instead?
It seems like thereβs a race between this deadline and how the connection is used. After 1 nanosecond the connection expires and goes away from the pool, so I get non-deterministic tls handshake failures
Sometimes 1 or 2 requests work before tls handshake error hits. Sometimes it directly fails on the first request:
```
go run main.go
2019/08/27 16:48:17 request complete
2019/08/27 16:48:17 Get https://www.example.com: tls: use of closed connection
exit status 1
```
```
go run main.go
2019/08/27 16:48:21 Get https://www.example.com: tls: use of closed connection
exit status 1
```
Apparently the conn is actually being used for tls handshake, possibly because 1 nanosecond is too low so that when the connection is established, it goes away just before TLS handshake starts.

486,141,996 | godot | texelFetch() not behaving properly | ___
***Bugsquad note:** This issue has been confirmed several times already. No need to confirm it further.*
___
**Godot version:**
3.1.1 stable
**OS/device including version:**
Ubuntu 18.04.3 LTS
**Issue description:**
I was using the *texelFetch* method from GLSL for a shader when I suddenly noticed that the fetched pixels' colors were not identical to the original ones from the texture. Testing with a simple LUT image, most of the colors were being fetched darker than they really were (below are 2 images for comparison).
After some struggle, I noticed that the same shader is working as expected in both Windows and Mac. It might have something to do with Linux drivers or even updates, since it was working some days ago.
*Original Image*
*TexelFetched Image*
**Steps to reproduce:**
- Open the reproduction project below and run the main scene
- Toggle the 'TexelFetchImage' node's visible property to true/false. It should be equal to the "OriginalImage" node's colors.
- Windows/Mac: Both images are equal
- Linux: the 'TexelFetchImage' node renders a darker image

I would like to see an Ethereum name or address added to the ethereum field of the package.json file. This will allow consumers of the project to know a cannonical address to send funds to.

486,189,689 | TypeScript | Node module dependencies that use a triple-slash directive to reference libs poison the global scope | **TypeScript Version:** 2.x, 3.x
**Search Terms:** lib.dom.d.ts pollutes global scope, `name` is defined as never, `event` is defined as `Event | undefined`
See: https://github.com/AaronFriel/is-test/blob/4e235decffdfd3c137ea066f8462d57d2fc8d0f2/src/index.ts at the commit hash linked.
**Expected behavior:**
Given a `tsconfig.json` with `lib: []`, I would expect the following code to fail to build due to `$variable not defined` errors:
```ts
import is from '@sindresorhus/is';
function main() {
console.log(name);
console.log(event);
console.log(caches);
console.log(applicationCache);
console.log(parent);
}
```
**Actual behavior:**
See: https://github.com/AaronFriel/is-test/blob/master/src/index.ts for a **particularly egregious** example of this. It builds without any type errors. When running `npm run start`, it will throw a runtime error on the first `console.log`. If you remove that line, the next one fails, and so on, for the next 700+ lines.
General purpose libraries often need to be written to handle multiple versions of ES (ES5, ES6, ES7...) and multiple host environments (e.g.: DOM, ScriptHost, WebWorker). But right now they are faced with a choice:
A: Use a triple slash directive to import types that they use, and poison the user's global scope, causing *nearly one thousand variable names* to be silently accepted as defined without any type checker errors.
B: Remove the triple slash directives and require that users use the `--skipLibCheck` option or equivalent in their config file or include the required libs in their compiler options. Otherwise the library will fail to type check.
This is a choice that library authors would quite reasonably not want to make.
**Potential solutions:**
1. Triple slash directives should import types only in dependencies.
This seems tricky to implement, I think.
2. There should be a types-only version of the major lib files, so that general-purpose utility packages can reference those instead.
This seems less tricky: extract all the types from the `dom` lib a new `dom-types` lib, and use a directive to reference the types. Then, library authors can triple-slash reference `dom-types` and get only the types. Has the advantage of not causing any compatibility issues, and library authors can opt in to the types-only package.

486,213,629 | TypeScript | [Proposal] Conceptual(virtual) module in .d.ts | ## Motivation
A common requirement during JavaScript application development is to bundle multiple modules together. There are many bundling tools to do this, such as rollup.js, webpack.
The usual case is that library maintainers organize their source in a internal structure. When publish, bundling tool is called to roll all modules up into one. Users of the library can only see the bundled module. They don't know and don't care about the original structure.
Everything works fine except when library maintainer wish to provide type declaration file(s) for the library so users can benefit from Typescript. Because Typescript compiler can only generate declaration files according to the original source structure. Even the compiler option `outFile` is used, it just produce a single declaration file which contains multiple "ambient" modules. For the declaration file's consumer, they can still see and refer to the original module.
For example. Say there is a library has the following source structure:
index.ts
```ts
export { Apple } from "./apple";
export { Pen } from "./pen";
```
apple.ts
```ts
export class Apple {}
```
pen.ts
```ts
export class Pen {}
```
Bundling tool bundle the index.ts to generated a single module "applepen.js".
Typescript compiler generate the declaration file like this:
```ts
declare module "apple" { export class Apple {} }
declare module "pen" { export class Pen {} }
declare module "index" {
export { Apple } from "./apple";
export { Pen } from "./pen";
}
```
It would be better to replace module name `"index"` to the library's real name. It can be done if the triple slash directive is inserted into `index.ts`:
```ts
/// <amd-module name="applepen"/>
export { Apple } from "./apple";
export { Pen } from "./pen";
```
It will infer the tsc to generate the declaration file like:
```ts
declare module "apple" { export class Apple {} }
declare module "pen" { export class Pen {} }
declare module "applepen" {
export { Apple } from "./apple";
export { Pen } from "./pen";
}
```
Now you can use the declaration file as:
```ts
import { Apple, Pen } from "applepen";
```
Yes, that's really what we expect. The declaration of "applepen" exactly match what bundling tool does.
Is that OK? No. Users are able, according the typing information the declaration file expresses, refer to a module called "apple". So:
```ts
import { Apple } from "apple";
```
is valid and cause no compiling error. But it's wrong because there is no "apple" module exists.
Even if we can carefully write any import statement, we are losing the convenience to use Typescript language server's auto-completion. That's mean when you type:
```ts
const apple = new Appl
```
The IDE will infer you Apple from a non-existing module "apple";
-------------
A kind of tools may helper, such as [dts-bundle-generator](https://www.npmjs.com/package/dts-bundle-generator) or [gift](https://www.npmjs.com/package/tfig)(the author is me :) ). But they are hack and problematical.
--------------
This proposal is aims to overcome the above issue.
## Solution
### Concept
A **conceptual module** is a kind of ambient module that cannot be used outside the non-conceptual module enclosing it.
Conceptual modules are only used to express structure. No any actual JS codes are generated for them.
To declare a conceptual module, you should use the module-declaration syntax, with the following restricts:
- Conceptual modules are only valid in declaration file(*.d.ts file);
- There shall be one non-conceptual _ambient_ module enclosing it(ie. `declare module "xx" {}`);
- The name element in module-declaration AST shall obey the rule of standard module specifier(ie. shall be a string-literal);
### Example
```ts
declare module "applepen" {
module "apple" {
export class Apple {}
}
module "pen" {
export class Pen {}
}
export { Apple } from "apple";
export { Pen } from "pen";
}
const apple: import("apple").Appe; // Error: cannot resolve module "apple"
```
In above example, there are two conceptual module "apple" and "pen" in non-conceptual module "applepen". All portion in module "applepen" can import the two conceptual module. Outside the "applepen" module can not, however:
A use case:
another file:
```ts
import { Apple } from "applepen"; // OK
import { Pen } from "pen"; // Error: cannot resolve module "pen"
```
### Implementation
The syntax of "A module declaration is enclosed in other one" is supported already. The only things need to be done are:
- Add codes to `resolveExternalModule()` in `Checker.ts` to support resolve conceptual modules;
- Code-completion stuffs.
## More information
The second restrict described above requires the enclosing non-conceptual module to be "ambient". It actually a restrict from current Typescript.
In current, a module in .d.ts like
xx.d.ts
```ts
module "ambient-module-with-no-declare-modifier" {
}
```
is an error. The Typescript requires it have a `declare` keyword modifier. But it is indeed recognized as a module which just has the `declare` modifier in type checker.
If it is REALLY treated as an error. The second restrict can be modified as:
- There shall be one module-declaration or source file enclosing it;
So we can define our bundle as not a "ambient" module, instead, as an "external" module:
applepen.d.ts
```
module "apple" {
export class Apple {}
}
module "pen" {
export class Pen {}
}
export { Apple } from "apple";
export { Pen } from "pen";
```
## Checklist
My suggestion meets these guidelines:
- [x] This wouldn't be a breaking change in existing TypeScript/JavaScript code
- [x] This wouldn't change the runtime behavior of existing JavaScript code
- [x] This could be implemented without emitting different JS based on the types of the expressions
- [x] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
- [x] This feature would agree with the rest of TypeScript's Design Goals. | Suggestion,Awaiting More Feedback | low | Critical |

486,341,476 | flutter | [Error message]Add a better debug message, when a child definition is missing | ## Use case
During development, sometimes very nice debug messages pop up saying something like "Either this is ... or we should provide a better error message".
Therefore I would like to propose to add some information for a scenario that I encounter very often, which is forgetting to define the "child" key.
E.g. when I write:
```dart
body: Column(
children: <Widget>[
RaisedButton(
Text('Button Text');
)
]
)
```
the error
`too many positional arguments: 0 allowed, but found 1. Try removing the extra positional Arguments.`
pops up.
IMO, this is not at all helpful for a beginner. (And if I recall correctly, 'positional arguments' is a rarely if at all used term in the documentation - but I might be wrong, haven't read the whole thing yet, but a lot, and it is not a term that is in my mind...)
I have a feeling that this error most often will pop up, when the "child" key was not mentioned (this is even mentioned as a possible reason on one of the Flutter videos on Youtube by a core dev).
## Proposal
Therefore I would like to suggest to add a bit more text to that error message that mentions the possibility that the child key was not found, too. I could think of a short text like this:
```
Error: too many positional [...] arguments. Or did you simply forget to add a "child" key?
```
Since I personally like the friendly style of the error messages in some places ver much, simply because it is a very motivating style of informing the dev that something is wrong, it would be great, if this style of addressing a possible error could be used.
But maybe a missing "child" key is even something that can be tested separately, so that in case of a missing "child" key a separate error message could be thrown?
This is just a suggestion and subject to discussion, of course. Thank you! | framework,c: proposal,a: error message,P3,team-framework,triaged-framework | low | Critical |

486,429,878 | pytorch | Handling of packed_sequence by activation functions and linear layers | ## π Feature
It would be absolutely great, more efficient and simplify usage of batched processing of variable length-input, if activations functions and linear layer could handle packed_sequences.
## Motivation
I noticed that it is not possible to feed ```packed_sequences``` to things like activation functions or linear layers. With NLP applications in mind, it forces me to design models having a forward method like :
```
def forward(self, input, lengths, hidden = None):
input = nn.utils.rnn.pack_padded_sequence(input, lengths, batch_first = True, enforce_sorted = False)
out, hidden = self.lstm(input,hidden)
out = nn.utils.rnn.pad_packed_sequence(out, batch_first = True, padding_value= -100)[0]
out = self.drop_layer(self.sigmoid(out))
out = self.softmax(self.linear_layer(out))
```
Where I have to unpack the ```packed_sequence``` directly after the passing through ```LSTM```, and later need to filter it before loss calculation. if I don't, I received an error message :
```
TypeError: sigmoid(): argument 'input' (position 1) must be Tensor, not PackedSequence
```
This seem highly inefficient since a lot of the calculations done by the activations functions and linear layers will have to be thrown away afterwards.
There might be an explanation as to why this is not already implemented, but I could not find a reason for it anywhere.

486,457,021 | pytorch | ConstQuantizerPtr is misnamed | I saw this in TensorMethods.h
```
// This is temporary typedef to enable Quantizer in aten native function API
// we'll remove them when we are actually exposing Quantizer class
// to frontend
using ConstQuantizerPtr = const c10::intrusive_ptr<Quantizer>&;
```
By standard C const precedence rules, "ConstQuantizerPtr" implies "const Quantizer*" but this is in fact NOT what you have here, which is effectively a "Quantizer * const" (because const binds more tightly to quantizer, so you have `const Quantizer`). Importantly, `ConstQuantizerPtr` doesn't stop you from mutating a quantizer, because you can "cast" away the constness.
Additionally, the type in question isn't even a pointer, it's a reference!
If Quantizer is the target of an intrusive pointer, I'd expect to actually see the naming as `struct QuantizerImpl` and then `using Quantizer = intrusive_ptr<QuantizerImpl>`. Then you could validly name the typedef above as `ConstQuantizerRef` although it would be a lot clearer to just not having the typedef at all.

486,634,397 | flutter | Consider tracking plugin entitlement requirements via pubspec.yaml | For sandboxed macOS appsβwhich may well be the default, but we want to support regardlessβthere are going to be cases where plugins require entitlements in the app (e.g., `camera`). The current solution to this kind of problem on mobile is to document it in the plugin docs, but that's error-prone, and may not be easy to debug.
In the new pubspec.yaml plugin format, we could add a key for macOS where plugins could list the entitlements they require. At build time we can collect the transitive list of those declared plugin entitlements, compare it to what's in the entitlements file, and warn/error if any are missing. (We could potentially have tooling for adding them automatically, but as @jmagman pointed out that's tricky since it's a user-owned file, and we don't want to stomp their changes).
(This general approach might be something we want to consider for mobile as well.)

- OpenCV => 4.1
- Operating System / Platform => Ubuntu 18.04
- Compiler => gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0
##### Detailed description
OpenCV segfaults when using cv::divide with the same input and output. I've attached a code snippet and the backtrace below.
##### Steps to reproduce
Unfortunately my code is quite complex and I can't upload all of it, but this is the gist of it:
```
cv::Mat resized, normalized;
cv::resize(kRawImage, resized, cv::Size(kModelInputDim_, kModelInputDim_));
resized.convertTo(normalized, CV_32FC3, 1/255.0);
normalized -= cv::Scalar(0.485, 0.456, 0.406);
cv::divide(normalized, cv::Scalar(0.229, 0.224, 0.225), normalized);
```
Backtrace:
```Thread 21 "runner" received signal SIGSEGV, Segmentation fault.

486,689,176 | opencv | more use of Mat_<_Tp>? | I'd like to bring up the issue that puzzles many newbies and users of the Eigen library and that is the need to hardcode element types in code using OpenCV. I'll take an example from [`cv::Mat::at`](https://docs.opencv.org/master/d3/d63/classcv_1_1Mat.html#aa5d20fc86d41d59e4d71ae93daee9726):
```
Mat A(100, 100, CV_64F);
for(int i = 0; i < A.rows; i++)
for(int j = 0; j < A.cols; j++)
A.at<double>(i,j) = 1. / (i + j + 1);
```
Notice the need to repeat the element type in code, rather than it being inferred from the object's type. OpenCV *does* have a `Mat_<_Tp>` which takes care of this.
```
Mat_<double> B(A); // converts elements implicitly
for(int i = 0; i < B.rows; i++)
for(int j = 0; j < B.cols; j++)
B(i,j) = 1. / (i + j + 1);
```
`Mat_` even supports range-based for loops over elements! In C++17 those could even be improved by [providing an iterator over (index,value) pairs](https://www.codingame.com/playgrounds/2205/7-features-of-c17-that-will-simplify-your-code/structured-bindings) that could look like this (and possibly have a solution in C++11 too):
```
Mat_<double> C(A);
for (auto& [index, value]: C.indexed())
value = 1. / (index[0] + index[1] + 1);
```
OpenCV APIs would benefit from using statically typed matrices (`Mat_<_Tp>`). You could get type errors at compile time. Less repetition reduces chances of error. All that would change is that a function gets templated overloads. The old signature using cv::Mat is still there.

### What did you do?
My tcp long connection server , Deploy a go program per machine. each go program deal about 800 000 user.
Usually my cpu utilization is only about 30%οΌBut gc will burst to over 95%. This causes my application to occasionally generate traffic delay jitter during gc. There will probably be some processing time of 2-3 seconds or more (including json.marshal,net.dial, metux lock, base64 decode and any others).
I observed the gc log and the runtime sched log. The conclusion is that the gc concurrent scan takes up a lot of cpu and knows that my business has no remaining cpu available. I observed that about a quarter of the procs are used for gc, no allocation proc for other tasks. I don't understand why gc cost lots of my cpu so that my business has no cpu resources available for a while, so my business has delayed jitter. Is there any solution or whether it can limit the numbers of cpu?

In the WebExtension content script, globalThis !== window.
So when `const requestAnimationFrame = window.requestAnimationFrame`, the `this` binding of `rAF` is lost.
In the after calling, `rAF` rebinds to the globalThis, but globalThis doesn't implements Window interface.

486,758,330 | rust | NLL issue when using DerefMut to access fields through a Pin, causing multiple mutable borrow error | The code below doesn't compile due to multiple mutable borrows, however the exact same code without the `std::pin::Pin` compiles fine actually. My expectation is however that the code would obviously compile fine in both cases.
```rust
use std::pin::Pin;
use slab;
struct Entry {
complete: u64
}
struct Ctx {}
impl Ctx {
fn new() -> Self {
Ctx{}
}
fn pread<T>(&mut self, _key: T) -> std::io::Result<()> {
Ok(())
}
}
struct Foo {
ctx: Ctx,
handles: slab::Slab<Entry>
}
impl Foo {
fn new() -> Self {
Foo {ctx: Ctx::new(),
handles: slab::Slab::with_capacity(20)}
}
fn blah(mut self: Pin<&mut Self>) {
let v = self.handles.vacant_entry();
let key = v.key();
match self.ctx.pread(key) {
Ok(()) => {
v.insert(Entry{complete:123});
},
Err(_) => {
}
}
}
}
fn main() {
Pin::new(&mut Foo::new()).blah();
}
```
The exception raised is:
```rust
error[E0499]: cannot borrow `self` as mutable more than once at a time
--> src/main.rs:31:15

| ^^^^ second mutable borrow occurs here
32 | Ok(()) => {
33 | v.insert(Entry{complete:123});
| - first borrow later used here
error: aborting due to previous error
```
I'm able to get the code to compile also by creating additional scopes around the areas where I'm supposedly borrowing `self` like this:
```rust
let key = {
let entry = self.handles.vacant_entry();
entry.key()
};
match self.ctx.pread(key) {
Ok(()) => {
*self.handles.get_mut(key).unwrap() =
Entry { complete: 123 };
}
```
Although obviously that's pretty awkward. I'm told that this could possibly be a bug in the NLL, but I'm pretty new to the language so I'm just reporting this with a short reproducible example.

consider this scenario
1) I am using google colab, I want to see the implementation of nn.Dropout
2) I ctrl+click on nn.Dropout, it takes me to dropout.py, where I find Dropout class, which returns
`
F.dropout(input, self.p, self.training, self.inplace)
`
3) so, I ctrl+click on F.dropout, it takes me to functional.py, where I see this
`
return (_VF.dropout_(input, p, training)
if inplace
else _VF.dropout(input, p, training))
`
4) now, I am stuck, because this is a builtin, and only way for me to look at its code, is to search for this in github.
5) same thing happens when I want to see the implementation of nn.CrossMapLRN2d, it redirects to torch.group_norm, which is builtin.
6) similarly for view, permute, this way to understand what these builtins are doing becomes difficult
because of this I raised an issue in google colab, to provide a way to look at builtin_function_or_method, they told

No, there's no way to get directly to the source in this case.
In particular, for a .so, it could be a cython file, or it could be another kind of C extension (built via vanilla C/C++ code, or SWIG'd in, or something else completely). All we have is the installed package -- there's no way for us to trace that back to source, and in cases like this (torch is distributed as a .whl file) the source isn't included.

486,862,701 | rust | Tracking issue for const fn pointers | Sub-tracking issue for https://github.com/rust-lang/rust/issues/57563.
This tracks `const fn` types and calling `fn` types in `const fn`.
---
From the RFC (https://github.com/oli-obk/rfcs/blob/const_generic_const_fn_bounds/text/0000-const-generic-const-fn-bounds.md#const-function-pointers):
## `const` function pointers
```rust
const fn foo(f: fn() -> i32) -> i32 {
f()
}
```
is illegal before and with this RFC. While we can change the language to allow this feature, two
questions make themselves known:
1. fn pointers in constants
```rust
const F: fn() -> i32 = ...;
```
is already legal in Rust today, even though the `F` doesn't need to be a `const` function.
2. Opt out bounds might seem unintuitive?
```rust
const fn foo(f: ?const fn() -> i32) -> i32 {
// not allowed to call `f` here, because we can't guarantee that it points to a `const fn`
}
const fn foo(f: fn() -> i32) -> i32 {
f()
}
```
Alternatively one can prefix function pointers to `const` functions with `const`:
```rust
const fn foo(f: const fn() -> i32) -> i32 {
f()
}
const fn bar(f: fn() -> i32) -> i32 {
f() // ERROR
}
```
This opens up the curious situation of `const` function pointers in non-const functions:
```rust
fn foo(f: const fn() -> i32) -> i32 {
f()
}
```
Which is useless except for ensuring some sense of "purity" of the function pointer ensuring that
subsequent calls will only modify global state if passed in via arguments.

I am unable to use a .png image as a linear texture inside 3d rendering. Linear in 2d works as expected but the setting seems not to effect 3d use. The import settings I used are:
<!-- What happened, and what was expected. -->
Changing the import settings from sRGB enabled to disabled should change the interpretation of the color but the resulting rendering is unchanged. (Also it seems there is always a R8G8B8_SRGB texture created internally for OpenGL).
This screenshots shows the expected behaviour in 2d (and the unchanged beaviour in 3d):
**Steps to reproduce:**
Apply a .png texture to the albedo and toggle the import settings Srgb between enabled/disabled and reimport.

### Actual behaviour
When searching for something, and `wrapscan` is not set, and the search is not found `E385` or `E384` is shown, depending on the search direction. Another case is if a search is made using `*` or `#` the same error gets repeated every time `n` or `N` is pressed, cluttering `mess`.
### Expected behaviour
I propose a new `shortmess` option, maybe `e`, that silences, `E385` and `E384`.

486,918,604 | pytorch | [DRAFT] Auto-casting in JIT - Automatic mixed precision | ## π Feature
<!-- A clear and concise description of the feature proposal -->
We want to support automatic precision casting as a JIT optimization pass. This is part of a grand plan to improve PyTorch performance by leveraging hardware acceleration on reduced precision arithmetics.
For more background and motivation, on automatic mixed precision, #25081 provides far more details.
## Motivation
<!-- Please outline the motivation for the proposal. Is your feature request related to a problem? e.g., I'm always frustrated when [...]. If this is related to another GitHub issue, please link here too -->
Whitelist-blacklist auto-casting has been proven to work on many models through Apex AMP. Dispatcher auto-casting, as proposed in #25081, would work in similar fashion. But auto-casting done through graph mode provides a global view of the computation graph that eager mode does not see, which gives us the opportunity to further improve the performance of auto-casting regarding both computational efficiency and numerical reliability.
Because of the static graph, the decision of cast insertion could be optimized globally. Consider the two following scenarios:
1. Cascading operations:
```
%2 : Tensor = at::BlackOp0(%1)
%3 : Tensor = at::ClearOp0(%2)
%4 : Tensor = at::WhiteOp0(%3)
```
Eager mode would cast data to fp32 at `%2 : Tensor = at::BlackOp0(%1)` ; Since `%3 : Tensor = at::ClearOp0(%2)` doesn't mind precision, it will transparently handle the data passed in as fp32; Tensor would be casted to fp16 when entering `%4 : Tensor = at::WhiteOp0(%3)`.
Graph mode, as we have visibility of the full sequence, we could make the decision that it is better to cast the output of `%2 : Tensor = at::BlackOp0(%1)` to fp16. This is numerically safe as `at::ClearOp0` would not be affected by reduced precision. More importantly here, It is computationally beneficial as we are reducing memory traffic at `at::ClearOp0` with reduced precision.
2. Branches:
```
%2 : Tensor = at::BlackOp0(%1)
%4 : Tensor = at::WhiteOp0(%3)
%5 : Tensor = at::ClearOp0(%2, %4)
%6 : Tensor = at::ClearOp1(%5)
%7 : Tensor = at::EndOp0(%6)
```
Depends on whether `%7 : Tensor = at::EndOp0(%6)` is numerically safe with reduced precision (white-listed or black-listed), it implores different casting policy for `%5 : Tensor = at::ClearOp0(%2, %4)`.
Because we don't want to use reduced precision when it's not numerically safe or performance-wise beneficial. If there is no whitelist operation on the path between two blacklist operations, it is hard to justify the performance benefit outweighing the numerical risk of reduced precision.
## Pitch
<!-- A clear and concise description of what you want to happen. -->
We want a graph optimization pass mutates the graph by inserting casting ops at appropriate places. The mutated graph would have identical numerical behavior and improved computation efficiency due to reduced precision.
### Implementation:
The optimization pass would be implemented as:
1. Graph Partition: mark nodes in the graph as black/white
2. Insert Cast Ops:
1. Run `CustomFuseGraph`: Try to fuse white nodes and put them under a custom fusion group;
2. Insert cast ops at the boundary outside of custom fusion group;
3. Cancel out inserted cast ops across blocks;
4. Inlining custom fusion group back into the graph;
A quick note just to avoid very likely confusion:
- _[Phase 1 Graph Partition]_ do *NOT* mutate the graph. We can be very aggressive in painting white nodes, as long as itβs numerically safe;
- _[Phase 2 Insert cast ops]_ *ONLY* inserts cast ops in the graph. So it should *NOT* undermine future optimization passes;
- _[Phase 2 Insert Cast Ops]_ `CustomFuseGraph` is used here only to handle data dependency, it has nothing to do with kernel fusion (which uses `FuseGraph` in a similar manner);
### Rationals the proposed implementation:
1. Graph Partition
We use a graph painting approach: The technique starts with painting whitelist-blacklist nodes in the graph; It then traces data flow to propagate the color information to not-yet-painted nodes. Doing so it partition the nodes according to whether itβs painted white or not.
One tip here is, we maintain the partition in a separate list without mutating the graph. This allows us to simplify partition logic without worrying about undermining the semantics of the graph.
We can start with the simplified technique:
1. Mark all blacklist nodes in the graph as black
2. Mark all whitelist nodes in the graph as white
3. Mark all nodes in a segment, which starts and ends with black nodes without any white nodes in the path as black
4. Recursively grow white nodes along both input/output edges to neighboring un-colored nodes until reaches a black node.
2. Mutability-safe optimization passes
Auto-casting will change the semantics of the graph. To safely insert a cast op in the graph, we need to ensure that our casting will not leak through data dependency, implicitly introduced by aliasing in PyTorch JIT IR. For example, if we have a graph like:
```
%2 : Tensor = prim::opA(%1)
%3 : Tensor = prim::opB_(%2)
%4 : Tensor = prim::opC(%2)
```
We should be aware that inserting a cast before node `%3 : Tensor = prim::opB_(%2)` would cause node `%4 : Tensor = prim::opC(%2)` to be in the same precision. This would not be safe, if `%3 : Tensor = prim::opB_(%2)` is painted white, while `%4 : Tensor = prim::opC(%2)` is painted black. In this scenario reduced precision has breached in the unsafe region.
Unfortunately there is no API that allows efficiently data dependency query in our infrastructure yet. Otherwise, we would be able to follow the implicit dependency introduced by aliasing to properly partition graph to avoid such violation.
In order to accommodate this, we need to make sure that we are not inserting cast ops immediately before an in-place operator, which means that graph partition should not cross the edge where down-stream operation either mutates input or returns alias(es) of input(s).
Because our graph partition follows only direct edged in the graph and does not consider aliasing, we can only fix this after the partitioning. The baseline approach is, that we iteratively check all boundary edges and update the painting if we detect violations. Note any update to the painting would change the boundary, so we have to check the new boundary edges as well.
Alternatively, to avoid handling tricky dependency analysis, we use existing `CustomFuseGraph` to fuse all white nodes into a custom FusionGroup. *THIS HAS NOTHING TO DO WITH THE FUSION GROUP WHICH WE USE TO GENERATE FUSED KERNEL.*
`CustomFuseGraph` uses `AliasDb` to track data dependency across the `FusionGroup` when merging nodes, which ensures that we can safely cast inputs to reduced precision without leaking. We then immediately inlining custom FusionGroup back into the original graph. This psuedo-fusion would be transparent and would not interfere following optimization passes.
Comparing to the baselin approach, using `CustomFuseGraph` has the following advantages:
- Simplifies the code;
- Has the potential to benefit from future dependency analysis improvement (maybe we will be extending support to in-place operators).
3. Hierarchical blocks
One limitation of existing pieces: `CustomFuseGraph` and `AliasDb` does not work across hierarchical blocks. This means white nodes fusion would also be limited within a block. This could be addressed by having an additional pass that propagates casts across blocks and fuses (cancels out) consecutive casts.
A complication in JIT IR: hierarchical blocks inside `prim::If` and `prim::Loop` requires some attention when we trace the edges connected to them.:
`prim::If` has two nested blocks that does not have input, as we trace the outputs to `prim::If` nodes, we should redirect that to corresponding `prim::Return` on both blocks;
`prim::Loop` has a single block with input and output, special care should be given at: a. Offset of each tensor as input and output for the node and block is different; b. Loop-carried dependency/dataflow should be considered.
## Future topics
<!-- Add any other context or screenshots about the feature request here. -->
1. JIT pass API
- How to exposure this optimization pass properly? Currently we will just expose this as a manual jit pass under `torch._C._jit_pass_auto_casting`
- How to handle Backward? If we apply our optimization pass before the gradient computation, cast op would be automatically handled, and operations not in `differentiableGraph` in the backward path would also benefit from reduced precision.
2. More complicated graph partition
- NVIDIAN folks have developed more complicated painting logic in TensorFlow-AMP, where they incorporated graylist nodes, which they claim to cause numerical issues for downstream blacklist nodes. We could work on our partition policy if we ever observe similar issues.
3. Compatibility with eager mode scripting
- #25081 proposed to use `With enable_autocasting():` to expose explicitly control to the user. How can we expose this control through graph mode? With statement is not yet fully supported inside script.

Because of that asynchronous design choice, it's not possible to acknowledge whether the feature tied to the controller is **currently** closed.
As a practical consequence, the only way to know if a snack-bar is currently opened is by checking whether its duration is greater than the time since it was opened, but this is not a reliable source since the user may have manually dismissed the snack-bar. This problem created a flaw in my tiny library that allows the user to press the back-button twice to close the app: https://github.com/hugocbpassos/double_back_to_close_app/issues/2

While scrolling, it is sometimes useful to see the current output (bottom of the view) at same time and even be able to type commands on prompt while seeing distant content in scrolled view without aborting the scrolling (e.g. to copy from long manual pages). In these situations it would help if (when enabled) scrolling would automatically split the view pane into two panes: static pane and scroll pane. Either with horizontal splitter (then static pane would be the bottom pane and scroll pane would be the upper pane) or vertically (then static pane would be the left pane and scroll pane would be the right pane). Scrolling would only take place in the scroll pane, static pane would always show the bottom lines of the view.
<!--

-->
Proportion of the panes should be configurable e.g. by specifying the size of the static pane either in percents or in number of lines. Setting this to 0 or 0% would effectively disable this feature.
The splitter could be moved using drag'n'drop/keybindings as well. If typing on command prompt wouldn't abort scrolling in this mode (this could also be optional), there should be a button and keybinding to abort the scrolling (this abort scrolling command would be effectively same as move-scrollbar-to-bottom command).
The content of the scroll pane shouldn't move with additional content appearing in the terminal to allow user to read/copy the content without disruptions. (only the scrollbar would move in such case to reflect the change of position of the scroll pane in the whole scroll buffer).

The drawer already has a controller class called `DrawerController ` which has open/close callbacks and a few other things, but Scaffold creates a default `DrawerController` if `Scaffold.drawer != null`.
**My suggestion**
Giving a optional parameter where you can insert your own `DrawerController`. If no controller was given, it creates a default controller just like it does now.
I'm hoping this could allow customizing the drawer's actions with less lines of code.

487,138,368 | pytorch | Add a mode to check input tensor sizes in allreduce_coalesced | @jfc4050 added CPU `allreduce_coalesced` in #24949. The current version flattens all input tensors into one, and then allreduce that tensor. It works, even if, say, process 0 provides a tensor of size 4 and process 1 provides two tensors of size 2 each. This is a reasonable shortcut to avoid using additional communications to check tensor sizes, but it will be good to add size checking in the default mode, and asking users to explicitly set `check_sizes=False` to they indeed want to skip that.

487,141,643 | flutter | Discrete Slider/RangeSlider has interpolation (?) errors | ## Steps to Reproduce
1. Create a discrete Slider/RangeSlider with `min:0.0`, `max:35.0`, `divisions: 35` (or see [main.dart](https://gist.github.com/repentsinner/3b635247f37c28f11a6a3a9700ec781d))
2. Build on Windows & run on a Pixel 2 or build on MacOS and run on an iPhone 7.
3. Slide any of the thumbs to the 29th position.
4. Expect the value to be 29.0, but instead receive 29.000000000000004
This also happens with:
| max/divisions | value |
|---------------|--------------------|
| 22 | 14.999999999999998 |
| 23 | 12.999999999999998 |
| 25 | 7.000000000000001, 14.000000000000002 |
| ... | |
| 35 | 29.000000000000004 |
| 38 | 21.000000000000004 |
| 39 | 25.000000000000004, 30.999999999999996 |

Current workaround is to insert `.roundToDouble()` methods in all of the `onChange*` callbacks to clean up the values before passing them out to the consumer.

487,175,873 | TypeScript | "Go To Type Definition" for type names should navigate to the type definition | "Go To Type Definition" doesn't doesn't work when the selection is itself a type. Instead, you get a "No type definition found" error. I can understand why it was implemented in this way ("types don't have a type!") but IMHO this behavior unnecessarily inconsistent and confusing for users. If I ask for the type definition of a type, then I should be taken to the... type definition! ;-)
I'm filing this at @weswigham's request to split it out of #6209. IMHO, if #6209 is implemented as I'm suggesting (where Go To Definition would navigate to the actual implementing source, not the DefinitelyTyped .d.ts) then fixing this issue would be helpful because it'd make both operations more consistent:
* Go To Definition would always navigate to implementation code (not to type declarations), regardless of what symbol is selected.
* Go to Type Definition would always navigate to type declarations, regardless of what symbol is selected
## Search Terms
Go to Type Definition
No type definition found for
`getTypeDefinitionsAtPosition` - this is one possible method to change in a PR
## Suggestion
Go to Type Definition should, when called for a type, return the location of the type definition.
## Use Cases
Discussed above
## Examples
```ts
type X = {a: number};
const a: X = {a: 1};
```
In VSCode, select and right-click on the second `X` and choose Go To Type Definition.
Expected: navigates to declaration
Actual: `No type definition for 'X'`
## Checklist
My suggestion meets these guidelines:
* [x] This wouldn't be a breaking change in existing TypeScript/JavaScript code
* [x] This wouldn't change the runtime behavior of existing JavaScript code
* [x] This could be implemented without emitting different JS based on the types of the expressions
* [x] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
* [x] This feature would agree with the rest of [TypeScript's Design Goals](https://github.com/Microsoft/TypeScript/wiki/TypeScript-Design-Goals).

On a bezier curve track, if you click on the little bezier curve on the right you can now edit the curve. There are however some issues when doing this:
If you select keyframes in it, and try Edit / Scale selection, after you enter a scale ratio, nothing happens. (Also the name is a bit ambiguous in this context as scale can be on the time axis or on the values axis)
If you right click on the tracks list on the left it behaves like it's not there and shows the menu for inserting the keyframes under it.
If you drag the <-> icon right next to "+ Add Track" it will only move the header timeline, you need to scroll so the window will refresh with the updated positions.
If you select the keyframes here, you are no longer able to edit their values from the inspector panel.
Keyframe selection in curve editor is different than the normal keyframe selection. If you select a keyframe then click on the bezier icon, the selection in the bezier editor is the last one you used in the bezier editor not your current keyframe selection.
(Also is there a way to scale the curve vertically? I've copied a bounce track and hoped I could use it for the alpha channel so I needed to scale the values from hundreds to 0..1 interval)
While playing with it I got the following errors in the console
> ERROR: _process_operation_list: Error calling method from signal '_clear_selection_for_anim': 'AnimationBezierTrackEdit::_clear_selection_for_anim': Method expected 0 arguments, but called with 1. At: core/undo_redo.cpp:291.

487,212,581 | create-react-app | Allow modular SCSS import and avoid duplicated styles on development mode | ### Is your proposal related to a problem?
<!--
Provide a clear and concise description of what the problem is.
For example, "I'm always frustrated when..."
-->
We've been trying to use a SCSS module oriented design system that provides a way to explicitly import the SCSS modules as needed when creating styles for a given component.
``` scss
@import "~@some-repo/design-system/base"; /* settings, mixins, extends */
@import "~@some-repo/design-system/page"; /* utility classes and general stylings */
@import "~@some-repo/design-system/bridge/buttons"; /* button specific styles */
```
This is fine when generating the final build, because any duplicated css will be ignored.
But when running the project in development mode, duplicated styles are prepended to the head section of the generated html file
### Describe the solution you'd like
<!--
Provide a clear and concise description of what you want to happen.
-->
A solution to this problem would be to add an opt-in configuration for doing something like this:
https://github.com/maoberlehner/node-sass-magic-importer/tree/master/packages/node-sass-once-importer
This would allow for the generated prepended style tags to avoid duplicated styles:
``` scss
// Example:
@import 'style1.scss';
@import 'style1.scss'; /* Duplicated on a different component .scss file */
@import 'style2.scss';
```
Generates:
``` scss
// Contents of style1.scss:
.selector1 { }
.selector2 { }
// Contents of style2.scss:
.selector3 { }
.selector4 { }
```
### Describe alternatives you've considered
<!--
Let us know about other solutions you've tried or researched.
-->
This: https://github.com/webpack-contrib/sass-loader/issues/145#issuecomment-173984354
And also, importing all SCSS modules that are common to more than one component style into the main .scss file and add ad-hoc scss modules as needed into this main file (not ideal as it would limit us from sharing the components with embedded styles)
### Additional context
<!--
Is there anything else you can add about the proposal?
You might want to link to related issues here, if you haven't already.
-->
I'd love to hear of any other alternatives you might have used that wouldn't require us to import all base files when using the design system.
I've considered using CSS Modules and CSS in JS, but this would limit us from making the design-system framework agnostic

487,352,049 | flutter | Feature request: Make listeners removable inside function body. | ## Summary
Add a way to remove a controller's listener inside the listener's function body for cleaner code.
## Use case
A use case a lot of community members and I have come across is when you want to conditionally cancel a subscription when results are coming in, ie., inside the listener's function body. This means you would either have to declare the listener beforehand so there's a reference to the listener that you can pass to the controller's `removeListener` method, or call a function outside the function body that has access to this listener. Both have negative consequences; in the first approach, the listener object will be mutable, and in the latter, two functions need to have access to this listener object which adds a preventable side-effect.
In our experience, this problem is most prominent in animation listeners and stream listeners.
Example of how it's done currently using `AnimationStatusListeners`:
```dart
Future<void> show() {
final completer = Completer();
AnimationStatusListener listener;
listener = (AnimationStatus status) {
if(status == AnimationStatus.dismissed) {
completer.complete();
_controller.removeStatusListener(listener);
}
};
_controller.addStatusListener(listener);
return completer.future;
}
```
## Proposal
### Approach A (breaking)
A `VoidCallback` function that's passed to the listener called something along the lines of `removeSelf`. This function can be called inside the listener's function body and will cancel the subscription.
Example of the proposed approach using `AnimationStatusListeners`:
```dart
Future<void> show() {
final completer = Completer();
_controller.addStatusListener((AnimationStatus status, VoidCallback removeSelf) {
if(status == AnimationStatus.dismissed) {
completer.complete();
removeSelf();
}
});
return completer.future;
}
```
### Approach B (non-breaking)
Add a method, `listenUntil` for example, that adds a listener that automatically cancels itself as soon as it returns true. Alternatively, add an optional parameter to existing `addListener` functions called `until` of type `bool Function(MyType)`.
Example of an approach where a new method, `addStatusListenerUntil` is added:
```dart
Future<void> show() {
final completer = Completer();
_controller.addStatusListenerUntil((AnimationStatus status) {
if(status == AnimationStatus.dismissed) {
completer.complete();
return true;
}
return false;
});
return completer.future;
}
```
Example of an approach that adds an optional parameter to the existing `addListener` methods:
```dart
Future<void> show() {
final completer = Completer();
_controller.addStatusListener(
(AnimationStatus status) {
if (status == AnimationStatus.dismissed) {
completer.complete();
}
},
until: (AnimationStatus status) {
completer.isCompleted;
},
);
return completer.future;
}

<pre>
$ go version

### Does this issue reproduce with the latest release?
Yes.
### What did you do?
I tested the behavior of the gc given a chain of address taking operations (I know these are pretty contrived examples):
1. https://godbolt.org/z/3zXWuG
1. https://godbolt.org/z/-8Qr0N
1. https://godbolt.org/z/_msJAW
1. https://godbolt.org/z/czEAhU
### What did you expect to see?
I expected functions 1/2 to compile to a simple return of -1 and 3/4 to a return of x.
### What did you see instead?
Instead, all the functions contain unnecessary instructions:
1. Extra `mov` through the variable `x`
1. Extra `mov` through the variable `x` and extra nil check
1. Extra nil check
1. Extra nil check

487,487,929 | three.js | Water2 fragment shader does not support Z-up WCS | ##### Description of the problem
The calculation which blends reflection and refraction fragment color assumes a default Y-up coordinate system to determine the blend amount. As a result, the transition between reflectance and refractance in a Z-up scene (or if the water surface doesn't lie in the xz-plane) happens while the camera is orbited around the scene, instead of while being tilted up and down. I was able to adjust the shader by trial and error, adding the following to line 339 of `examples/jsm/objects/Water2.js`:
```glsl
vec3 adjustedEye = vec3(toEye.x, toEye.z, toEye.y);
float theta = max( dot( adjustedEye, normal ), 0.0 );
```
Which simply swaps the z and y coordinates for this calculation only. It would be nice if the shader works for any camera-up and plane orientation by taking into account the normal of the surface to which it is applied, however my lack of GLSL knowledge prevents me from coming up with a solution.

In a recent blog, your team indicated you could position a background image to your liking. Currently it appears on the very edge of the display (no gap). It would be nice to be able to specify an offsetX/offsetY setting, respecting backgroundImageAlignment to determine which sides of the image to apply the offset to, so that you could indent the image. The idea is that most people will use this to position a large-size icon somewhere in the window to make it super-obvious at a glance which shell is being displayed. Currently to get a gap you need to manually insert a gap around your image, and getting the transparency right isn't necessarily easy.

487,597,213 | godot | Call to Thread.wait_to_finish() in my scene hangs in Windows but not Linux | **Godot version:**
v3.1.1.stable.official
**OS/device including version:**
Linux/X11 and Windows 10
The same issue was observed across two Windows 10 machines and two Linux machines.
**Issue description:**
In a function I start a thread, yield until a signal from the thread is received, and then call `Thread.wait_to_finish()`. On Linux this produces the desired effect of doing work in the background without stopping a playing animation, but on Windows the call to `Thread.wait_to_finish()` never returns. I think it's a bug that Windows and Linux have different behaviour in these scenarios; it seems to me that the Linux behaviour should be the "correct" one, as I can't see any reason why Thread.wait_to_finish() should hang in that scenario.
**Steps to reproduce:**
I've included a sample project ([Thread_test.zip](https://github.com/godotengine/godot/files/3560890/Thread_test.zip)). `with_signal.tscn` prints:
```
This is a thread!
Thread is done!
```
on Linux, but on Windows 10 it hangs and never prints the second line.
I've also included `no_signal.tscn`, which demonstrates the workaround I've used for now. | discussion,topic:core | low | Critical |

I think it'd be helpful to document the RAM requirement. That way, if the tests run out of memory on a machine that meets the minimum requirements, it becomes easy to determine that the problem lies with the tests and not the machine. The responsibility division is unclear when the requirements are unspecified.
This is similar to issue #19046 but for x/tools.

- TensorFlow installed from: binary
- TensorFlow version: v1.14.0-rc1-22-gaf24dc9 1.14.0

**Describe the current behavior**
Calling `seek()` on a `tf.gfile.GFile` opened in write only mode raises `tensorflow.python.framework.errors_impl.PermissionDeniedError`.
**Describe the expected behavior**
GFile should support the Python IO semantics that supports seeking on a write only file.
More generally it would be preferable if GFile followed the API of Python's [`io.IOBase`](https://docs.python.org/3/library/io.html#io.IOBase).

487,712,959 | pytorch | Multithreaded backpropagation with custom autograd.Functions | ## π Feature
By using DataParallel, the engine creates a thread for each GPU. It should do this for backpropagation too, including within python-implemented autograd.Functions.
## Motivation
We're trying to implement synchronized batchnorm for one machine/one "main" process using an interface like the traditional DataParallel. To synchronize the forward pass (computation of the mean+variance) we use a threading.Barrier to sync the threads for each GPU.
As it turns out, torch's batchnorm uses a custom backwards function which gives a different gradient than you'd get just from doing a linear transform with the mean and variance: https://github.com/pytorch/pytorch/blob/v1.1.0/aten/src/ATen/native/Normalization.cpp
To implement a SyncBatchNorm that behaves identically on multiple GPUs as torch's batchnorm does on one GPU it looks like we'd need to synchronize things like the mean of grad_output across all GPUs. But we can't get our .backward to be entered by multiple threads simultaneously to pull this off.
## Additional context
At first we were concerned that torch might not multithread backprop at all, which would be a huge slowdown for multi-GPU training, but it looks like it does for C implemented functions only? I can't find any clear documentation.
