440,829,066 | flutter | Create onLoad event in SearchDelegate | ## Use case
I need to show a list of users when loading the SearchDelegate screen. Taking in consideration the [API](https://docs.flutter.io/flutter/material/SearchDelegate-class.html) there is nothing that allows me to load something based or not in the query and that is only triggered once.
Playing with `buildResults` and `buildSuggestions` take me nowhere, specially because the events keep firing whenever I write anything in the SearchInput.
## Proposal
Create an event that fires only on load.

440,831,515 | flutter | Allow to disable AutoFocus in input using SearchDelegate | ## Use case
Allow to disable the auto-focus being done in the input of the SearchDelegate. This feature is also related to [this feature request](https://github.com/flutter/flutter/issues/32153). If something is being fired in the `onLoad` event it might be counterproductive to have the keyboard immediately open because of the focusness.
## Proposal
Convert this:
```
showSearch(
context: context,
delegate: MyDelegate(),
query: '',
);
```
Into this:
```
showSearch(
context: context,
delegate: MyDelegate(),
query: '',

440,858,791 | go | cmd/go: do not download “modules” that contain no go.mod or *.go | At the moment, `go mod download` will happily try to extract and download any arbitrary repository as long as it can be resolved by some means (through a hard-coded hosting service such as `github.com`, or using a distinguished extension like `.git`), even if it does not contain anything even marginally related to building Go code.
I am not aware of any reasonable use-case for such a repository:
* It's not useful for storing test data, because we currently provide no mechanism for the tests to actually locate that data. (Modules are not guaranteed to be loaded from the module cache — for example, they might be subject to a `replace` directive — and since the test itself is run within the directory containing its source code, it has no way to locate the data or run `go list` within the module that invoked it.)
* It's not useful for C headers (for use with `cgo`), for the same reason.
* It _might be_ useful for fetching non-Go inputs to `go generate`: in theory, the generator could run `go mod download $MODULE` to locate the sources at the required version. But the output of `go generate` is intended to be checked in anyway, which makes the use of modules somewhat spurious: if an explicit version of the non-Go inputs appears in the module's requirements, then everyone using the generated package will have an extra module to fetch that is guaranteed to have no effect on the build, and in most cases the `go generate` program can just as easily `git clone` (or similar) the input data at a specific revision.
Furthermore, if someone _did_ find a way to make modules without Go source code useful (for the above use-cases or others), it's trivial to add a `go.mod` file to indicate that the repository really is _somehow_ intended for use with Go source code. (We need to support `go.mod`-only modules anyway, since they can arise naturally when splitting a large root module into smaller nested modules.)
----
On the other hand, module proxies tend to rely on the `go` command to decide what is or is not a valid module, and accepting arbitrary non-Go repositories potentially exposes such proxies to a significant amount of additional load.
----
Therefore, I propose that we change the `go` command to explicitly reject any “module” that both contains no `.go` source files **and** lacks a `go.mod` file.

If this has to do with https://pytorch.org/tutorials, please file an issue at https://github.com/pytorch/tutorials/issues/new -->
I raise this issue because I encountered many warnings and errors compiling the documentation.
I checked out version 1.1.0, and followed the instruction of "Building the Documentation" by running pip install -r requirements, and then make latexpdf. I already have texlive, latexmk, and other necessary latex packages installed. My system is Ubuntu 19.04.
Errors include missing references, missing "$", extra alignment, etc. Given how verbose latex's error list is, I am not listing everything here. I can upload a log file of the errors if that is desired.
Is there any specific version of latex that is required?
The reason I try to get a PDF is that PDF is so much better as a single file format when I don't get internet. PDF readers can handle very long PDF files smoothly, while my browser had a hard time to load a large single-file html is hard to handle by my browser. In this use case, PDF is overall a better solution.
On the other hand, I don't really know where the errors originated (the docs, Sphinx, or latex version). So, **maybe a better solution would be providing a downloadable PDF file of every release on the website**? I suppose that if the pytorch team already have a testing pipeline for documentation generation, it wouldn't be too much work to post the pdf file on the website. However, I don't really know if that fits into your pipeline.

440,991,972 | vue | ability to keep `enter-to` class after show transition completes | ### What problem does this feature solve?
In some CSS libraries, i.e. Bootstrap, many components have opacity set to `0` by default, and only have opacity set to `1` when a class is applied. i.e. Bootstrap's `fade + show` classes:
```css
.fade:not(.show) { opacity: 0; }
```
The current `<transition>` behaviour does not support retaining the `enter-to-class` (as it is immediately removed once the transition completes).
Currently one has to use javascript hooks and VM data to add/remove the `show` class, which makes it impossible to make re-usable transition components, as simply adding a class via javascript to the `el` reference (via `el.classList.add/remove('show')`) doesn't guarantee persistence if the content in the default slot manipulates it's own classes, meaning the transition component _must_ be integrated into the custom component, not as a re-usable utility wrapper component).
### What does the proposed API look like?
It would be nice to either be able to retain the `enter-to-class` class after the transition completes, or create a new prop that provides this behaviour for a particular class name i.e. `enter-to-retain-class`. The class would be removed on leave.
The other option would be to create a new prop `active-class="classname"` which is added one frame after insertion, and removed when the leave transition is to start (basically rolling the `enter-to-class` and `leave-class` into one prop, but retain the class until leave is initiated)

const aName = example[a]; // Type of aName is string and should be "ONE" | "TWO" | "THREE". Or even "ONE" since a is const
console.log(aName); // Prints "ONE";
```
The implicit type of aName is _string_ and should be "ONE" | "TWO" | "THREE" since those are the only possible values. Or even "ONE" since a is a constant.

441,115,204 | neovim | missing redraws when rpcrequest() is used in statusline expression | This is with recent nvim HEAD, and also manifested with a version some month back. I did not investigate if there are older versions which behave correctly here. The RPC plugin in question is [here](https://github.com/KillTheMule/nvimpam/tree/impro) (take care to take the `impro` branch), so it's not minimal in any way. I might get around to produce something more minimal in python or so.
If you cloned the repo, then in the master directory first you need to compile the plugin (`cargo build`, needs a rust installation), and then you can produce the error from running `nvim -u init.vim files/example.pc` as follows:
1. Start the plugin with `:NvimPamAttach`
1. move to line 50, which reads
```
NODE / 22 20.20000076 50.5 30.
```
3. Run `3f2`, and then `i<Space><Esc>` to insert a space.
* What happens: The space is inserted, no highlighting applied.
* What should happen: Space inserted, highlighting applied
4. Run `x` to remove the Space inserted in 1.)
* What happens: Space is removed, the highlighting from 1.) is applied
* What should happen: Space is removed, a different highlighting should be applied
Note that the status line involes a function that runs a request to the plugin, namely `CellHint`,
which interweaves with all other communication of course. This seems to cause trouble.
When I keep doing edits, it very much looks like the highlighting applied is always lagging 1 action behind. A filtered neovim log is at https://gist.github.com/KillTheMule/12378fae90419f539be2d44b48bc0547 which only includes steps 3.) and 4.). These can be seen from line 37 (the update event from inserting a space) to line 51, where the plugin answers the "CellHint" request from neovim (which is a consequence of the statusline being updated). Just to be clear, the log looks perfectly fine to me, it's just that the highlights are not applied at the right time, but "one action later".
@justinmk already looked at it in gitter, and I could provide the following additional answers:
* When using `<C-l>` inbetween, the correct highlighting will be applied
* Using `:redraw` inbetween does not change anything
* Setting `lazyredraw` does not change anything
He also suggested `as a workaround setting a "dummy" highlight e.g. nvim_add_buf_hl(..., 'Normal', 1,1) i.e. highilight line 1, column 1 with "Normal" highlight every time you add a real highlight` which I will try tonight (or so...) | bug,api,channels-rpc,display | low | Critical |

### What did you do?
Standard crypto/tls library is incompatible with CA certificates (either root or intermediate one) when they contain Trust Settings (https://www.openssl.org/docs/manmaster/man1/x509.html#TRUST_SETTINGS):
<pre>
$ openssl -in rootCA.crt -text -noout
...
No Trusted Uses.
No Rejected Uses.
Alias: XXX
...
</pre>
Since widely used MS AD-based CAs DO have such Settings in their certs, it is hard to use encrypted connections in golang programms in such environments.
### What did you expect to see?
The successfull TLS-handshake.
### What did you see instead?
In our case server's cert is issued by intermediate CA which is issued by root CA and `server.crt` contains server's cert followed by the intermediate CA's one.
In the case when the Trust Settings are present in the intermediate's cert, tls-negotiation fails with the following errors:
client.go:40: tls: failed to parse certificate from server: asn1: syntax error: trailing data
server.go:55: remote error: tls: bad certificate
If only the root's cert contains the Settings, the errors are slightly different:
client.go:40: x509: certificate signed by unknown authority
server.go:55: remote error: tls: bad certificate
(Example client&server apps are available at https://github.com/kruftik/go-tls-vs-windows-ad-ca, build.sh prepares binaries)
Once the Settings are being stripped from both root and intermedia CA certs with the `openssl x509 -in rootCA.crt -out rootCA.clean.crt` command, the problem is going away.

441,238,331 | rust | CP15 barrier instructions should be emitted before the exclusives loops (arm) | ## Symptoms
* Rustup hangs (unable to install Rust)
* Tracked down to [parking_lot](https://github.com/Amanieu/parking_lot/issues/130) issue
* Not just Rust related, [Swift has this problem as well](https://forums.balena.io/t/cloud-build-fails-but-local-device-build-works-on-raspberry-pi-zero/4994)
* -> LLVM issue
## Environment
* Linux kernel with`CP15_BARRIER_EMULATION=y`
* `abi.cp15_barrier` set to `1` (emulate)
* `arm-unknown-linux-gnueabihf` toolchain
## CP15 barrier instructions
* They're deprecated since `armv7`
* Linux kernel can [emulate or HW exec them](https://www.kernel.org/doc/Documentation/arm64/legacy_instructions.txt)
* `abi.cp15_barrier` is set to `2` (HW exec) -> there's no issue
* The CPU must support them
* ARMv8 in our case, which still supports them
* `abi.cp15_barrier` is set to `1` (emulate) -> there's this issue
## Issue description
`parking_lot` author:
> This seems to be closer to an LLVM bug than a parking_lot bug. The source of the problem is the CP15 emulation in the kernel. Essentially the `mcr p15, #0x0, r12, c7, c10, #0x5` is trapping to the kernel every time, which invalidates the exclusive monitor between the `ldrex` and `strex` instructions. This results in the `strex` never succeeding and looping indefinitely.

## Solution
Will's third point:
> Atomic read-modify-write operations with conditional release semantics (i.e.
> release on success) should actually emit the CP15 barrier before the
> exclusives loop. Assuming that contention is rare (which it kind of
> needs to be for performant compare-and-swap anyway), I don't see this
> having a meaningful impact on performance.
And:
> I've reached out to one of our upstream LLVM developers, and I'll be talking
> with him face-to-face next week about getting this fixed.
I asked for the LLVM bug # to track it, but still no response.
## Way forward
* Fix it on the Rust LLVM fork
* Wait for the LLVM to have this fixed and wait till Rust's fork synces
Second way can prolong fix by weeks, months, ...? Not sure how fast is the LLVM itself developed & how fast is the Rust's fork syncing. This is the main reason I did report it here as well.
## No fix
People aren't / won't be able to use Rust on Linux with `CP15_BARRIER_EMULATION=y` & `abi.cp15_barrier=1` (emulation, default value) & `arm-unknown-linux-gnueabihf` toolchain. | A-LLVM,O-Arm,T-compiler,C-bug,A-atomic | low | Critical |
441,257,306 | go | testing: parallel benchmark results are poorly documented | The way parallel benchmark results are reported is easy to misinterpret, and the correct way to interpret them is not documented. Typically this makes perfectly-scalable benchmarks appear to perform much worse at low parallelism, and makes not-at-all-scalable benchmarks appear to be doing fine. For example, this came up in https://github.com/golang/go/issues/31820#issuecomment-489112014
Specifically, the "ns/op" reported is not CPU-ns/op, it's wall-ns/op. For example, suppose each op takes exactly 100 ns, regardless of parallelism. If the single-threaded benchmark runs for 1 sec, it will execute 10,000,000 ops, so ns/op = 1s/10,000,000 ops = 100 ns/op. But if the same benchmark runs 4-way parallel for 1 sec, it will execute 40,000,000 ops, so ns/op = 1s/40,000,000 = 25 ns/op. (I really wish it didn't work this way...)
Interpreting the results of CPU-bound parallel benchmarks is further complicated by hyper-threading (though this isn't the fault of the testing package).
I don't think we can change the reported ns/op at this point. We could perhaps introduce a new metric for parallel benchmarks. At the very least, we should document this. | Documentation,NeedsFix | low | Major |

441,338,418 | rust | Behavior of panicking Drop::drop is not properly documented | It was decided in, I think, #14875, that `Drop::drop` can panic, and if this happens, the value must be leaked (at least in a generic context), that is, it cannot be re-dropped again and doing that could invoke UB (that's at least what generic unsafe code needs to assume).
This does not appear to be documented anywhere. These semantics make the following snippet have undefined behavior due to double-drops ([playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=8aa124ceb7a72d954497891d29cf4004) uses `T = Vec<HasDrop>`):
```rust
let mut a: T;
let a_raw = &mut a as *mut T;
match std::panic::catch_unwind(|| {
// Drop `a` in place:
unsafe { std::ptr::drop_in_place(a_raw) };
}) {
// For exposition only, if the value isn't leaked,
// it will be re-dropped, but one could also try to
// explicitly re-drop on drop failure.
// UB: this will double-drop some previously dropped fields of a
Err(_) => std::mem::drop(a),
// If dropping succeeds, leak a
Ok(()) => std::mem::forget(a),
}
```
To avoid UB, that snippet must be changed to unconditionally leak the value independently of whether `drop_in_place` succeeded or failed:
```rust
let mut a: T;
let a_raw = &mut *a as *mut T;
std::panic::catch_unwind(|| {
// Drop `a` in place:
unsafe { std::ptr::drop_in_place(a_raw) };
});
// Always leak `a`: if dropping failed, some elements will be leaked,
// but there is no way to properly drop them and trying to re-drop
// a could invoke UB
std::mem::forget(a);
```

## Steps to Reproduce
<!--
Please tell us exactly how to reproduce the problem you are running into.
Please attach a small application (ideally just one main.dart file) that
reproduces the problem. You could use https://gist.github.com/ for this.
If the problem is with your application's rendering, then please attach
a screenshot and explain what the problem is.
-->
1. ... Use animateCamera in onTap of marker
2. ... Tap the marker
3. ... Tap it again and again
4. ... There should be no movement, since the camera position is already reached
In my case I got a bottom sheet that might fill the half of the screen. Therefore the default behavior that centers the tapped marker does not suit the case.
That's why I calculate an offset to center the marker in the upper part of the screen.
When taping it again and again (see the screen video) sometimes the usual center animation is started, but then interrupted by the one from my onTap callback. Causing a jump.
On Android the camera move is overwritten like expected.

// I detect if F is `any` by checking if F extends `never`.

readonly symbol property
## Suggestion
Expose `isReadonlySymbol` as a method on `TypeChecker`.
Currently there's no way to tell for sure if a property is readonly.
While cumbersome userland implementations can check for `readonly` modifier in `Symbol.declarations`, if it's a GetAccessor without corresponding SetAccessor or if it originated in `Object.definePropery(this, 'propName', {value, writable: false})`.
However, there's one more thing: `Readonly` mapped type only sets `Symbol.checkFlags` which is internal.
So at the very least I need an API to tell if a property's symbol comes from a mapped type with a `readonly` modifier.

441,475,211 | rust | powerpc64: allow querying ELF ABI version | There are two ABIs on ppc64, ELFv1 (legacy) and ELFv2 (introduced a couple years back, used by default for little endian). Rust currently has logic in it that for the `musl` libc, ELFv2 is used on big endian and ELFv1 is used otherwise. This is inadequate, as you can use ELFv2 as well with `glibc`. In my distribution, both little and big endian systems are supported, with `glibc` and `musl`, and they are all set up for ELFv2.
In order to achieve that, Rust in the distribution is patched so that it will always properly use ELFv2 ABI. However, this is a potential problem for some crates that for example need to deal with assembly code; they have no way to query the ABI version. For endianness, they can do like `#[cfg(target_endian = "big")]`. For ABI, there is no equivalent (in C, you can do `#if _CALL_ELF == 2`).
I can look into implementing this, but I need to know what would be the best syntax and way to implement this. As I see it, it would need a new field in the target options, but this would of course be specific to ppc64, and ABI on ppc64 in e.g. gcc is treated more like a list than a string (you can also have `-mabi=altivec`, `-mabi=ibmlongdouble` and so on, in addition to `-mabi=elfv2`), so I was wondering if something more generic/extensible would be better.
Of course, eventually it'd be best to also allow setting it when compiling, and make it properly pass everything down to llvm, but that's less of a concern, for now I just need crates to be able to read it. | T-lang,O-PowerPC | low | Major |

```
I believe the two LEAQs should instead be `ADDQ CX, AX`, `INC AX`. This would be six bytes of instructions instead of 8.
I need to double-check, but I believe that this happens because we optimize `a + b + const` to `LEAQ const(a)(b*1), dst`, but then break apart the three-part LEAQ.
We can't fix this when lowering to instructions, because LEAQ doesn't clobber flags and ADD and INC do. So we need to somehow catch this in the rewrite rules. I wonder whether we should reconsider the previous strategy of breaking apart "slow" LEAQs at the last minute (for https://github.com/golang/go/issues/21735).

441,562,744 | flutter | Flutter on iOS should support semantic autofilling of text fields | See https://github.com/flutter/flutter/issues/32265 for some context
We currently support password autofill, but not as nicely as we could. In a native iOS app, autofill works if there's a password box anywhere on the screen. After a bug fix for the linked issue, we only support it if the box has focus. We also only support passwords right now, but could be supporting other types of auto filled input (like user names, emails, etc.).
On issue with fixing this is that the framework currently increments the client id for a text input on each attach - and the engine has no knowledge of whether that client ID is for a new or existing text editing state. The framework also does not pass semantic information for the type of text entry wanted (beyond keyboard types anyway).
Another issue is that the engine reuses the backing fields that the OS can interact with for autofilling for multiple fields. It would need to have a way to track (and free) those backing objects per text field on the framework side. | a: text input,c: new feature,platform-ios,framework,engine,a: fidelity,P2,team-ios,triaged-ios | low | Critical |

For issues, feature requests, or setup troubles with Puppeteer, file an issue right here!
-->
### Steps to reproduce
**Tell us about your environment:**
* Puppeteer version: 1.15.0
* Platform / OS version: Ubuntu 16.04
* URLs (if applicable):
* Node.js version: v10.15.3
**What steps will reproduce the problem?**
_Please include code that reproduces the issue._
1. Run the following code, set headless to `true` or `false` and see the difference.
```
const puppeteer = require('puppeteer')
;(async () => {
const url = 'https://www.google.com'
const browser = await puppeteer.launch({
headless: false,
args: [
`--window-size=1920,1080`,
'--enable-experimental-web-platform-features',
'--disable-infobars',
'--enable-usermedia-screen-capturing',
'--allow-http-screen-capture',
'--auto-select-desktop-capture-source=webclip',
'--ignore-certificate-errors',
'--unsafely-treat-insecure-origin-as-secure=' + url
]
});
const page = await browser.newPage()
await page.setViewport({
width: 1920,
height: 1080,
})
await page.goto(url)
page.evaluate(async () => {
document.title = 'webclip'
const stream = await navigator.mediaDevices.getDisplayMedia({ video: true })
const recorder = new window.MediaRecorder(stream, { mimeType: 'video/webm' })
recorder.start(10)
const chunks = []
recorder.addEventListener('dataavailable', event => {
if (event.data && event.data.size) {
chunks.push(event.data)
}
})
})
})()
```
**What is the expected result?**
Maybe it should start recording (I don't know whether this behavior is intended and I haven't found percisely related information).
**What happens instead?**
Throw exceptions.

441,703,211 | flutter | flutter channel command output | ## Use case
When Dart 2.3 was announced I started to use it on flutter master channel because I really needed that. After some while, I needed to go back to the stable channel that didn't support Dart 2.3 at that time. So every time that I would like to know if Dart 2.3 was already on the stable channel, I had to change the channel to stable, upgrade it, and see my project breaks because Dart 2.3 was missing, and then go back to master channel.
## Proposal
The output of `flutter channel` command could be a table showing the version numbers and details of each channel instead of a list of names | c: new feature,tool,P3,team-tool,triaged-tool | low | Minor |

The `mat2_sizes` here is pointless; we can trivially reconstruct it from `mat2_`. So it's just a waste of space.

441,764,162 | pytorch | Linker errors when linking statically (avx perfkernels) [Caffe2] | ## 🐛 Bug
I've been trying to build the caffe2 v1.1.0 release and link it statically with our application, but I'm getting a lot of undefined symbols related to avx functions.
## To Reproduce
I've built caffe2 142c973f4179e768164cd578951489e89021b29c using the following flags:
```bash
$ cd pytorch
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/home/giachero/runtimes/caffe2-v1.1.0-avx -DBUILD_PYTHON=OFF -DUSE_CUDA=OFF -DUSE_NATIVE_ARCH=ON -DUSE_GFLAGS=OFF -DUSE_GLOG=OFF -DUSE_GLOO=OFF -DBUILD_SHARED_LIBS=OFF -DBUILD_TEST=OFF -DBUILD_BINARY=OFF -DUSE_LMDB=OFF -DUSE_LEVELDB=OFF -DUSE_MPI=OFF -DUSE_OPENMP=OFF -DUSE_OPENCV=OFF -DBUILD_ATEN_MOBILE=ON -DUSE_NNPACK=OFF -DCAFFE2_DISABLE_NUMA=1 -DUSE_QNNPACK=OFF
```
Minimal application code:
```c++
#include <caffe2/core/init.h>
int main(int argc, char *argv[])
{
caffe2::GlobalInit();
return 0;
}
```
Build flags:
```bash
$ g++ main.cpp -I /home/giachero/runtimes/caffe2-v1.1.0-avx/include/ -L /home/giachero/runtimes/caffe2-v1.1.0-avx/lib/ -Wl,--whole-archive -lcaffe2 -Wl,--no-whole-archive -lcaffe2_protos -lcpuinfo -lc10 -lclog -lonnx -lprotobuf -lonnx_proto -lonnxifi_loader -lm -lpthread -ldl -o test

```rust
#![feature(repr_simd, powerpc_target_feature)]

}
#[target_feature(enable = "altivec")]
pub unsafe fn splat_u32x4(x: u32) -> u32x4 {
u32x4::splat(x)
}
```
with `#[inline]` that code produces a function call within `splat_u32x4` (`b example::u32x4::splat`) to `u32x4::splat`, which is not eliminated, even though this method is module private. With `#[inline(always)]`, `u32x4::splat` is inlined into `splat_u32x4`, and no code for `u32x4::splat` is generated.
`#[inline]` should not be needed here, much less `#[inline(always)]`, yet without `#[inline(always)]` this produces bad codegen.
Removing the `#[target_feature]` attribute from `splat_u32x4` fixes the issue, no `#[inline]` necessary: [godbolt](https://godbolt.org/z/NeA-2w). So there must be some interaction between inlining and target features going on here. | A-LLVM,T-compiler,O-PowerPC,A-SIMD,C-bug | low | Critical |

-->
**Godot version:**
3.1.1
**Issue description:**
`get_node_name` doesn't work on any nodes other than `NODE_ELEMENT` and `NODE_ELEMENT_END`. Sometimes I want to get the name of a `NODE_TEXT`, which isn't possible. This is probably to avoid trying to get the names of `NODE_NONE` or maybe `NODE_UNKNOWN`. The docs state
```
Get the name of the current element node. This will raise an error if the current node type is not NODE_ELEMENT nor NODE_ELEMENT_END
```
**Steps to reproduce:**
Create a new `XMLParser`, load in an `xml` file with the first element being a simple text node, call `read()` and then `get_name()`.
Example text element:
```xml
<description>
Vector3 is one of the core classes of the engine.
</description>
```
**Workaround:**
Since the end of an element is always `NODE_ELEMENT_END`, you can get the name from that element.

But docs say:
```go
// NoGoError is the error used by Import to describe a directory
// containing no buildable Go source files. (It may still contain
// test files, files hidden by build tags, and so on.)
type NoGoError struct {
Dir string
}
```
(Notably, the "it may still contain test files" part, implying that a directory with only `foo_test.go` should be NoGoError).

<!-- Please try to reproduce the issue with `typescript@next`. It may have already been fixed. -->
**TypeScript Version:** 3.5.0-dev.20190508
<!-- Search terms you tried before logging this (so others can find this issue more easily) -->
**Search Terms:** restrictive return type
**Code**
```ts
class Box<A> {
constructor(public val: A) {}
}
interface ContainerFor<A> {
array: Array<A>;
box: Box<A>;
}
function single<T extends keyof ContainerFor<number>>(t: T, x: number): ContainerFor<number>[T] {
switch (t) {
case "array":
return new Array<number>(x);
case "box":
return new Box<number>(x);
}
return new Box<number>(0); // this should not be needed
}
function test() {
let t1 = single("array", 42);
let t2 = single("box", 42);
//let t3 = single("boo", 42);
}
```
**Expected behavior:**
This code worked with 3.4, but had an unsoundness bug in that `single` was allowed to return the wrong type (swap array and box). It was clear that switching over `t` did not increase knowledge about the expected output type and I was forced to have a fallback return which is of course unreachable. But the code itself worked.
The `test` function also shows things work as expected. The types for `t1` and `t2` are inferred correctly and asking for an unknown thing ("boo") is reported as an error.
I would expect this to still work in 3.5, perhaps fixing one of the issues I'm having in the internals of `single`.
**Actual behavior:**
Typescript 3.5 no longer accepts this code. returning `new Array` or `new Box` are flagged as wrong return types. The newly expected return type is now mandated to be the intersection type: `number[] & Box<number>`, which is too restrictive as the correct output type can be statically determined from `T` in the input. The fact that `test` correctly infers the output type is proof of this.

441,904,593 | flutter | [web]: Scrolling is very slow when displaying large Text | ## Versions:
Dart VM version: 2.3.0 (Fri May 3 10:32:31 2019 +0200) on "macos_x64"
Flutter 1.5.4-hotfix.2 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 7a4c33425d (9 days ago) • 2019-04-29 11:05:24 -0700
Engine • revision 52c7a1e849
Tools • Dart 2.3.0 (build 2.3.0-dev.0.5 a1668566e5)
## Issue
I was playing with Flutter Web and decided to put a HTTP response body (78KB) into a `Text` element. It causes the app to scroll very, very slowly.
Here's simplified code you can use to reproduce:
```dart
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Padding(
child: Text("Pull Requests"),
padding: EdgeInsets.all(5),
),
),
body: Center(
child: ListView(
children: <Widget>[
Text(Iterable.generate(10000, (i) => "Hello Flutter $i").join('\n'))
],
),
),
);
}
```

441,923,749 | go | cmd/go: 'list std' unnecessarily opens *_test.go files | While working in an environment with a slow filesystem (immediate stats+readdirs, but slow opens), I noticed that `go list std` was very slow (~6 seconds), which prompted me to look at what it was doing.
One thing that jumped out was that it's opening *_test.go files, which should not be necessary to answer the question of whether a directory in $GOROOT contains a Go package.
```
$ go install cmd/go && strace -f -e open,openat go list std 2>&1 | grep _test.go | wc -l
2181
```
That's about 37% of the overall files opened:
```
$ go install cmd/go && strace -f -e open,openat go list std 2>&1 | grep O_RDONLY | grep '.go"' | wc -l
5887
```
Overall, we read 67 MB in from disk just to answer `go list std`:
```
$ strace -o trace -f -e read go list std > /dev/null && perl -ne '$num += $1 if /.+?(\d+)/; END{ print "$num\n" }' < trace
67894893
```

441,947,867 | neovim | MSVC builds of same source are not identical | I've downloaded the `nvim-win64.zip` file of version 0.3.5 last week (2019-04-29).
I've downloaded the same file today (2019-05-08).
When I check the sha256 sums of the two files, they are different.
When I check the content of the files inside the zips (using FreeFileSync and WinMerge),
it appears that the following files have different contents.
`lua51.dll`, `msgpackc.dll`, `nvim.exe` and `uv.dll`
I have discussed this problem with people on IRC (#nvim).
After several tests, @justinmk advised me to make a diff on the two nvim.exe files.
He also advised me to read this link on StackOverflow : [Deterministic builds unde winwos](https://stackoverflow.com/questions/1180852/deterministic-builds-under-windows/10605862#10605862)
I used the tool advised on the SO post : [peparser](https://github.com/smarttechnologies/peparser).
After running the comparison on the two `nvim.exe` files, it appears that **the two files are "functionally" identical.**
The only differences are due to timestamps and other things produced by the compilation of files.
Here is an extract from `peparser`
```

441,982,367 | rust | ICE in LlvmArchiveBuilder when cross-compiling openssl for Android ARM64 | There is an ICE in nightly that I can trigger by adding a dependency on vendored openssl when cross-compiling for aarch64 android with the NDK. It's possible the problem here isn't really rustc's fault, but it does crash.
Test repo: https://github.com/thombles/rust-ice-openssl

This test case is a hello world app with a dependency that requires it to build and link openssl from source:

I run the following script to build it:
```

# Set this to location of Android NDK
NDK=/Users/tk/Library/Android/sdk/ndk-bundle/
# (Tested on NDK 19.2.5345600, installed via Android Studio SDK Manager)
# Set this to your platform - probably "darwin-x86_64", "windows-x86_64", "linux-x86_64"
