##### System information (version)
<!-- Example
- OpenCV => 3.1.0
- Operating System / Platform => Windows 64 Bit
- Compiler => Visual Studio 2015
-->
- OpenCV => 3.1
- Operating System / Platform => Ubuntu 16.04 Linux 4 Tegra 24.2.1 aarch64 / Jetson TX1
- Compiler => g++ 5.4.0
##### Detailed description
<!-- your description -->
VideoCapture(string) constructor using a gstreamer pipeline string fails to open a stream, even though the stream can be launched with the same pipeline using gst-launch-1.0. Note that the VideoCapture(int) constructor succeeds at opening a stream with VideoCapture(0) -- although for me, the feed is blank because i currently have no usb camera connected to the tx1.
##### Steps to reproduce
Flash TX1 with Jetpack 2.3.1.
Build opencv 3.1.0 from source using the instructions found [here](http://docs.opencv.org/master/d6/d15/tutorial_building_tegra_cuda.html).
Add the following code to a cpp file named test.cpp
```.cpp
#include "highgui.hpp"
#include "videoio.hpp"
#include "imgproc.hpp"
#include <iostream>
#include <string.h>
using namespace cv;
using namespace std;
int main(int argc, char** argv)
{
string gst_pipe = "videotestsrc ! videoconvert ! appsink";
VideoCapture cap(gst_pipe);
if (!cap.isOpened())
{
std::cout << "Failed to open camera." << endl;
return -1;
}
for(;;)
{
Mat frame;
cap >> frame;
imshow("original", frame);
waitKey(1);
}
cap.release();
}
```
Build it with
```g++ -o test -I /usr/include/opencv2 -Wall test.cpp -L/usr/lib -l:libopencv_core.so.3.1.0 -l:libopencv_videoio.so.3.1.0 -l:libopencv_imgproc.so.3.1.0 -l:libopencv_highgui.so.3.1.0```
Run the resulting executable with ```./test```. Note that no stream is opened, and "Failed to open camera." is printed to the console.
<!-- to add code example fence it with triple backticks and optional file extension
```.cpp
// C++ code example
```
or attach as .txt or .zip file

200,524,359 | youtube-dl | Retrieve JSON data in unicode (Encoding UTF-8) | - [x] Bug report (encountered problems with youtube-dl)
- [ ] Site support request (request for adding support for a new site)

===================================================
I need JSON data containing unicode (utf-8) from Youtube-dl, sadly it couldn't retrieve JSON data from YouTube video in UTF-8 (?).
Trying to print JSON info with `-j, --dump-json` or `-J, --dump-single-json` , `--print-json` and or wrote directly into JSON file with `--write-info-json`. All results were printed in non unicode data string like originally of video source.
The paramaters which were used with/out `--encoding utf-8`
```youtube-dl --write-info-json --encoding utf-8 -f mp4 -o "%(title)s.%(ext)s" https://www.youtube.com/watch?v=0alnhFO1B7Y -v```
```youtube-dl -j --encoding utf-8 -f mp4 -o "%(title)s.%(ext)s" https://www.youtube.com/watch?v=0alnhFO1B7Y -v```
```youtube-dl -J --encoding utf-8 -f mp4 -o "%(title)s.%(ext)s" https://www.youtube.com/watch?v=0alnhFO1B7Y -v```
```youtube-dl --print-json --encoding utf-8 -f mp4 -o "%(title)s.%(ext)s" https://www.youtube.com/watch?v=0alnhFO1B7Y -v```
**The log output:**

200,659,064 | rust | Dead code lint emits unused code warning for code that is clearly used. | It looks like the dead code lint is too eager, and doesn't consider two signs that the variants are used:
- The enum is passed to an extern function, which could do just about anything to the data.
- The variants *are* used, in the match statement!
[Playground](https://is.gd/BDy0bB)
```rust
use helpers::Animal;

}

200,750,094 | flutter | Flutter should get AutoTransition (aka layout transition), where two Widgets can transition between each other | Lets say I have Widget A, which contains some widgets, and then I have Widget B, which contains some more widgets. Each side will have keys that match a source widget to a target widget. AutoTransition will match these up and animate them from their positions in Widget A to their positions in Widget B.
Android implements a feature similar to this with the Transition framework. I actually use this feature in an Android app of mine to expand and contract a music control overlay... Doing this manually in Flutter would not be fun.
I'm guessing (since I haven't touched Flutter internals much) that something like this would animate on the RenderObject layer. | c: new feature,framework,a: animation,P3,team-framework,triaged-framework | low | Major |

gofmt -r does not work well when rewriting multi-line expressions.
Given this code:
package x
func f() {
Foo{
X: 99,
Y: "hello",
}
}
running:
gofmt -r 'Foo{X: a, Y: b} -> Foo{
X: a,
Y: []byte(b),
}'
results in:
package x
func f() {
Foo{X: 99, Y: []byte(
"hello")}
}
In general, if the replacement expression contains multiple lines, their
placement is ignored. | NeedsInvestigation | low | Minor |
201,146,703 | node | What will Domain be replaced with? | I'm adding support for parallel tests to node-tap. https://github.com/tapjs/node-tap/issues/306
One sticky point is that, like most test frameworks, node-tap needs to be able to cleverly handle thrown errors and tie them to the test environment where the error was thrown from (especially since many existing assertion libs turn things like `expect(foo).to.match(/regexp/)` into a thrown error).
When tests were _not_ run in parallel, there was no problem. Just walk down the tree of `test.currentChild` or whatever, and a single `process.on('uncaughtException')` is sufficient.
I'm using Domains to manage thrown errors in child tests, and it works great, but the bright red deprecation notice in [the docs](https://nodejs.org/api/domain.html#domain_domain) is scary.
What will it be replaced with? Will it be feature-equivalent? If so, is there any reason why the existing API has to be broken, and not re-implemented in terms of the new thing? Is there an expected time frame for the Domain api to be broken?
Thanks. | question,domain | medium | Critical |
201,174,168 | nvm | Adding descriptions about symlinks in the 'nvm is not compatible with the npm config "prefix" option' error | I have ran into two machines that shows `nvm is not compatible with the npm config "prefix" option` error everytime `~/.nvm/nvm.sh` is invoked, and which is also mentioned by [existing issues](https://github.com/creationix/nvm/issues/1087).
In the end, I found that in both my machines, the home directories is symlinked to another location. By modifying the nvm load script `.bashrc` to set `NVM_DIR`to the path after symlink resolution, the error goes away for good. It works in new bash sessions as well.
That is, if in your machine it says something like
```
$ ls -l /home
lrwxrwxrwx 1 root root 9 May 7 2014 /home -> /srv/home
$ echo $HOME
/home/username
```
then your nvm will blow up with `nvm is not compatible with the npm config "prefix" option`. To correctly solve the issue, we should change `NVM_DIR` from `$HOME/.nvm` to something like `/srv/home/username/.nvm`.
I think the error message was useless in helping me figure this out. I spent some time tracing `nvm.sh`, inserting `echo` and disabling `--silence` to see my echo, to found that the system admin has setup those symlinks, and it *is* those symlinks that broke nvm.
Specifically, when the condition of [this `if`statement](https://github.com/creationix/nvm/blob/40e40975ebd3593d08c3f83de2546258f7ddf11d/nvm.sh#L2002) turns true, it does not necessarily means that `npm config get prefix` is set by another `npm` instance. It just means that `nvm` is not sure if the prefix is set by nvm itself. I think extending [the error message here](https://github.com/creationix/nvm/blob/40e40975ebd3593d08c3f83de2546258f7ddf11d/nvm.sh#L2007) to include the symlink issue can help others encountering this issue, since it is not uncommon to have home directories symlinked to somewhere else.

### Make parsed metadata variables (`--metadata-from-title`) available to output template (`-o`)
Presently, it appears as if the only metadata available to the output template engine is that returned by the `_real_extract()` function in the site-specific extractor.
So, in my example, PBS, the only real element available at the time the output template is processed is the title, id, and a few others. Indeed, if you look in the logs I pasted above it seems that the metadata extraction from title happens quite late, after files have been written.
To be general, this is not specific to the PBS extractor.
Desired behaviour: Make metadata variables extracted from the title also available to the file output template.
Proposed fix: Move the processing of `--metadata-from-title` earlier (during initial extraction, before writing (m)any files).
While writing this report I noticed issue #11108 which is another manifestation of this same problem. Note at the end someone correctly identifies that the metadata-from-title is not available as a variable to the output template. **In my view it would be more sensible to move this parsing earlier and make these variables available, instead of adding a whole 'nother parameter**, `--variables-from-title` as suggested in #11108
I haven't digested enough of the codebase yet to make the change myself. Thanks for your consideration. | request | low | Critical |
201,201,231 | go | debug/elf: add File.DynValue method to look up DynTag values | Currently there is no method/function to convert elf.Symbol.Info to SymBind and SymType, even thought there is a function ST_INFO to convert SymBind and SymType into uint8.
We probably should have created a new type for Symbol.Info, but we can't do that before Go 2.
Therefore I propose the addition of the following two methods to elf.Symbol:
```
func (s Symbol) Bind() SymBind {
return SymBind(s.Info >> 4)
}
func (s Symbol) Type() SymType {
return SymType(s.Info & 0xf)
}
```
Perhaps we could also make elf.Symbol implement Stringer, but I'm not sure about the format yet. Any suggestions?
Additionally, the elf package looks like automated conversion from elf.h as it contains a lot of top-level functions will non-idiolmatic names (R_INFO, R_SYM32, etc.) without any docs. For Go 2, we should get rid of them, and turn them into proper methods with idiomatic names.

var a = 42;
a && foo(); // 42
```
result in comment should indicate that foo was called. but in fact we would get same result of "42" if first operand had been called (like in `||` operator). i think results of `a` and `foo()` should be different to make the example be clearer.
for example:
```
function foo() {
console.log("foo");
}
var a = 42;
a && foo(); // "foo"

201,286,382 | opencv | Enhancement Objective C: Conversion using static category methods | In [OpenCV iOS - Video Processing](http://docs.opencv.org/2.4/doc/tutorials/ios/video_processing/video_processing.html#opencviosvideoprocessing) tutorial page there is a guide how to convert `cv::Mat` to `UIImage` and backwards. I have found much easier to use static methods inside category extending `UIImage` itself. I have created a [sample GIST](https://gist.github.com/tomas789/f54080e88e8cfa187228322823328c01). Please consider changing a tutorial using this approach so everybody can use it. Of course, anybody can implement it on his own but it is not that obvious to do it this way.
**Main advantages:**
- Very simple to use
- It can be used everywhere. Not only inside one class where it was implemented
- Copy paste only approach
- There might be folks that are not that familiar with Objective-C++ so them might not come up with this simpler approach instead of using the one proposed in current tutorial page.
**Disadvantages:**
- OpenCV is then included in every Objective-C++ class | feature,platform: ios/osx | low | Minor |

### Description of your *issue*, suggested solution and other information
When I try to download the audio and video (actually are animated gifs changing every 10 seconds) streams from the website http://archillect.com/tv, Youtube-dl downloads the audio stream properly but appears to fail to download the video one for some reason.
I have tried – without success – to solve this myself by asking for help on this site:

Could you perhaps see on your end where the problem is coming from?
Thank you very much for your time!

201,558,805 | node | 'end' event not called on connected socket wrapped with tls | * **Version**: v6.9.4, v7.4.0

* **Subsystem**: net, tls
When wrapping an existing socket with tls, the socket's 'end' event is not called if the socket was already connected.
Example:
In this case 'end' will be called:
```js
var Socket = require('net').Socket;
var tls = require('tls');
var HOST = 'www.google.com';
var socket = new Socket();
var tlsOptions = {
host: HOST,
socket: socket
};
socket.on('close', function() { console.log('close'); });
socket.on('end', function() { console.log('end'); });
var tlsSocket = tls.connect(tlsOptions, function() {
console.log('connected');
tlsSocket.end();
});
socket.connect({
port: 443,
host: HOST
});
```
In this case 'end' will not be called:
```js
var Socket = require('net').Socket;
var tls = require('tls');
var HOST = 'www.google.com';
var socket = new Socket();
var tlsOptions = {
host: HOST,

201,579,836 | rust | Guarantee that values in hash map are disjoint from each other and the HashMap struct. | There was some discussion about the unsafe guarantees of `HashMap` on Reddit[1] which inspired me to write this issue.
The current HashMap implementation has its entries at memory locations that are disjoint from each other and from the `HashMap` struct. That means that in principle, there could simultaneously exist multiple mutable references to different, disjoint values contained in hash map without aliasing happening. This idea is similar in principle to the reason why `split_at_mut` API on mutable slices can exist.
However, as the `HashMap` currently provides no guarantees for supporting the disjointness of its entries, no unsafe code is allowed to trust it – especially because `HashMap` is a part of the `std`, and we can't currently pin version dependencies to `std`; the implementation of `HashMap` is allowed to "silently" change and break unsafe code.
I think it would make sense to document what the current implementation does in practice as a guarantee: the values stored in hash map are disjoint from each other and from the `HashMap` struct. In practice, this disallows the following situations:
* The `HashMap` struct containing some of its values "inline", inside the struct.
* Some value `v1` containing an instance of another value `v2` (for example, a boxed struct that contains more boxed structs of the same type), and `HashMap` returning a reference to `v2` as a reference to "separate" value from `v1`.
To be sure, I don't mean that `HashMap` should necessarily guarantee that each key maps to a separate value – just that separate values don't alias. Also I don't propose an API that allows multiple unaliased mutable references to the values in hash map; but this guarantee can be seen as a preliminary requirement for such an API to exist in future.

201,726,835 | vue | v-on:change randomly fails on range input bound on a computed property | ### Vue.js version
2.1.10
### Reproduction Link
http://jsbin.com/bapoca/edit?html,js,console,output
### Steps to reproduce
The above JSBin contains a slider (range) that logs the value of a computed property it is bound to (`sliderRadius`), when it changes: `v-on:change="log"` (log is a declared function)
### What is Expected?
I would expect that each time the slider changes, the prop is logged in the console.
### What is actually happening?
Two different scenarios:
- you drag and release the slider handler (aka thumb): the prop is *always* logged in the console (i.e. the change handler fires properly all the times)
- you directly click where you want the handler to get to: the prop isn't logged all the times (i.e. the change handler fails about in 3 out of 5 occasions).

When Google CDN server peered or hosted by local ISP (blah-blah-blah.googlevideo.com) that holds media files is unavailable, youtube-dl just hangs on TCP connect and returns a system error after a timeout. It's an obvious, straightforward behavior. However, the website (at least default Javascript player served for Firefox) checks if any data from server is available after 5 seconds, and automatically reconnects to a different (global/anycast?) CDN server (in my case, r6---sn-4g57kn6e.googlevideo.com) to play the video. I guess they bothered to handle that case because of the total amount of Google cache nodes, and ubiquitous network problems and misconfigurations.
I think it's a rare case where youtube-dl is less resilient and useful than the official way of watching Youtube.
Steps to reproduce: set iptables to drop packets to CDN servers Google picks for your IP address range, check what player on the website does. | request | low | Critical |

[ ] support request => Please do not submit support request here, instead see https://github.com/angular/angular/blob/master/CONTRIBUTING.md#question
```
I'm facing a problem where I want to run different enter transitions depending on width of screen. With Angular 1 animation, based on css classes, it was really easy to accomplish different transition rules depending on media queries. You'd simply do something like (scss)
```sass
.ng-enter {
transform: translateX(-100%);
&.ng-enter-active {
transform: translateX(0);
}
}
@media (max-width: 600px) {
.ng-enter {
transform: translateX(100%);
}
}
```
... to have it slide in from right on small devices. Also the positioning/css etc. was close to where other parts of the styling was, so it was easy to match any pixel numbers etc. against other css declarations. With Angular 2's animation API, we currently see these downsides
1. We can't use media queries
2. Combinations with pseudo classes is impossible and you'd have to replicate e.g. hover with mouseenter/leave listeners etc. (see #10196)
3. They can't be put in css files for use by designers and non-programmers if you want them out of .ts/.js
4. It's harder to find where an animation is declared as it could be both in our typescript or css
This is a feature request for dealing with primarily with 1., but potentially the others as well. I can see the following solutions
1. You come up with some kind of syntax for adding media query abilities, along the lines of the #10196, maybe something like
```
state('@media (max-width: 600px) :enter', ...)
```
2. ...or states can be mapped to css classes as well, thereby allowing users to choose where to put animation logic, i.e. something like
```
state(':enter', addClass('enter'))
```
3. Or 2. is done automatically and you wouldn't have to write any ts/js if you didn't want to and could just do it like Angular 1
4. Or just not use `*ngIf` on outer element, bind an inner element via *ngIf and add classes to outer element, and use css transitions (possible today, but only if applicable css context allow you to nest extra elements)
5. Or use javascript to calculate that state (possible today, but cumbersome)
```
state('void => small', ...)
state('void => large', ...)
<foo *ngIf="..." [@myAnimation]="isLargeScreen ? 'large' : 'small'"
```
What are your thoughts. I'd personally prefer 3. as I think it allows most freedom and solves all bullets above. If you recommend 4. or 5., what are your thoughts about the downsides?

201,893,666 | rust | #![cfg] to disable a crate disables #![no_std] | Using `#![cfg]` to disable a crate on platforms where it makes no sense is usually a great idea. That way people can unconditionally depend on your crate and use it only on the targets where it is needed. However it disables the entire crate, including all global attributes, which means normally a crate that has `#![no_std]` wouldn't depend on std, but if you use `#![cfg]` to disable that crate, suddenly it does depend on std! The only workaround is to not use `#![cfg]` and instead manually disable each item in the `lib.rs`, except for specific attributes like `#![no_std]`.
For example:
```Rust
// rustc foo.rs --crate-type=rlib
#![no_std]
#![cfg(any())]
```
```Rust

If you are running many processes at once, and you don't know which one will finish first, this is inconvenient, because the system calls `wait` and `waitpid` consume each exit notification as they report it. (`waitid` can be told not to do that, but it is not fully supported in the libc crate yet.) That places the `Child` object in an inconsistent state, in which it is not safe to call `wait` or `wait_with_output`.
If `Child` had a `set_exit_status` method, an application in this situation could use it to keep the objects consistent: something like
```rust
fn wait_all(children: &[&mut Child]) -> nix::Result<()> {
use nix::sys::wait::{wait, WaitStatus}
let mut pending : HashMap<u32, &mut Child> =
children.iter().map(|c| (c.id(), c)).collect();

1. If a developer has a weird single frame jump they could use this to 'see' that frame better to aid in debugging.
1. If a developer relies on sizes from a previous frame in their app (which is bad in general) this would increase the jank caused by that to possible 'real world' levels. | c: new feature,framework,P3,team-framework,triaged-framework | low | Critical |

[ x ] bug report => search github for a similar issue or PR before submitting
[ ] feature request
[ ] support request => Please do not submit support request here, instead see https://github.com/angular/angular/blob/master/CONTRIBUTING.md#question
```
**Current behavior**
Sourcemaps are being added to each angular bundle from the perspective of the wrong directory. These sourcemaps are currently included in the latest (2.4.4) release when doing a fresh npm install.
Example from `node_modules/@angular/core/src/linker/compiler.js.map`
```
{"version":3,"file":"compiler.js","sourceRoot":"","sources":["../../../../../modules/@angular/core/src/linker/compiler.ts"],"names":[],
```
This is causing an unexpected/incorrect path to be displayed in debugging tools.
**Expected behavior**
Sourcemap paths should start from the npm repository's base directory. In this case the path should start from `modules/@angular/core`
Resulting in a path similar to this:
```
{"version":3,"file":"compiler.js","sourceRoot":"","sources":["src/linker/compiler.ts"],"names":[],
```
**Minimal reproduction of the problem with instructions**
Create a new project with Angular CLI beta.25-5
modify the file: node_modules/angular-cli/models/webpack-build-common.js:132
replace `exclude: [nodeModules]` with `exclude: /node_modules\/(?!(\@angular\/core)).*/`
*note: this is just to quickly include sourcemaps for @angular/core
run `ng serve`
Open the served page in Chrome and use developer tools > Sources tab
As a result (when using webpack) files appear to be in:
```
webpack://../../../../../modules/@angular/core/src/linker/compiler.ts
```
instead of
```
webpack://./~/@angular/core/src/linker/compiler.ts
```
**What is the motivation / use case for changing the behavior?**
Debugging Angular codebase from the context of a CLI project (I'm assuming whenever using webpack).

}
```
Invoke:
```
gorename -offset main.go:#51 -to apple
```
### What did you expect to see?
`rename` should also rename the receiver of the method `doit` from `b -> a`
The heuristic here should be that if the receiver does follow the generally accepted [naming advice](https://github.com/golang/go/wiki/CodeReviewComments#receiver-names) then `rename` can safely proceed and rename receivers.
### What did you see instead?
Renaming `banana -> apple` leaves the receiver of method `doit` as `b`

##### System information (version)
- OpenCV => 3.1.0-dev
- Operating System / Platform => Ubuntu 16.04
- Compiler => Python 2.7
##### Detailed description
I have difficulty implementing cv2.calcHist in Python. Based on OpenCV docs, I am trying to create a non uniform 2d histogram of float32 values. However, I get error with message "SystemError: error return without exception set" , when trying to input custom bin edges.
##### Steps to reproduce
Gives error:
```
import cv2
import numpy as np
r_d = np.random.random(100)
p_d = np.random.random(100)
r_bins_edges = np.linspace(np.min(r_d), np.max(r_d),100)
p_bins_edges = np.linspace(np.min(r_d), np.max(r_d),100)
H = cv2.calcHist([r_d.astype(np.float32),p_d.astype(np.float32)], [0,1], None,
(99,99),
[r_bins_edges, p_bins_edges])
```
Runs alright with no custom bin edges:
```
import cv2
import numpy as np
r_d = np.random.random(100)
p_d = np.random.random(100)
r_bins_edges = np.linspace(np.min(r_d), np.max(r_d),100)
p_bins_edges = np.linspace(np.min(r_d), np.max(r_d),100)
H = cv2.calcHist([r_d.astype(np.float32),p_d.astype(np.float32)], [0,1], None,
(99,99),
[0, 1, 0, 1])
```
Apart from that, notice that in the 'runs alright' part I am writing [0, 1, 0, 1] and not [[0, 1], [0, 1]] (as docs propose), which again gives the same error "SystemError: error return without exception set" . I believe this is an issue worth to be corrected, as cv2.calcHist() can not be interchanged with np.histogram2d in the present. (The example I gave has uniform bins, but in my application there are non uniform ones)

202,338,232 | go | cmd/compile: order.go is outdated | Many optimizations made in walk.go did not come with corresponding updates to order.go. For example, order.go makes a temporary for runtime calls for OCONVIFACE for many cases which walk special-cases not to make runtime calls. Another example is the introduction of temporaries for equality checks that walk inlines.
These do not impact correctness, but they might impact performance (if SSA cannot eliminate the pointless temporaries) and toolspeed (by generating useless nodes that then must be optimized away).
This issue is a reminder to investigate this, and decide whether it is worth the effort to modernize order.go.

202,348,041 | neovim | Restore cursor position when triggering undo | Something that has always bothered me about vim is that when you undo you often do not get your previous cursor position back. For example, given the following file (with the ^ character representing where the cursor is)
```
this is a test
^
```
If you hit `diwu`, you get this:
```
this is a test
^
```
Whereas what I would expect is for the cursor to be back at the original position. In many cases it does follow this behaviour but in many cases it does not. For example, typing `itest<esc>u` preserves the cursor position but typing `atest<esc>u` does not. Typing `Du` preserves position but typing `d^u` does not. Maybe there is some logic behind this behaviour that I'm not seeing but to me it seems odd.
Is this a change worth considering? Or maybe this something better suited as a plugin? | enhancement,normal-mode | low | Minor |

There should be a way to schedule pods based on network resource availability - could be on the similar lines as cpu and memory request/limits.
At the very least, kubelet or node-problem-detector should report network congestion or bottlenecks.
One specific use-case is when pods have low cpu/mem requirements, but high network bandwidth needs.

**Current behavior**

When using ReactiveForms and we override old form group with the new one (using for example `this.form = new FormGroup(...)`) an error occurs (the error is mentioned in the title).
(The error can be seen in console).

No error happens.

The error can be seen after 3 seconds (I used set timeout in the example). Error should be visible in console.
**What is the motivation / use case for changing the behavior?**
<!-- Describe the motivation or the concrete use case -->
I understand that this is not the best way to use form groups, i should check if they are already created, and create it only if necessary. However, this bug indicates (I concluded this from stacktrace) that control set-up doesn't work after it's been cleaned up. This should not be the case. Problem occurs because Angular's cleanUpControl function sets up change callback to its own handler (the handler just throws error), and then in setUpControl function, Angular calls write value BEFORE it registers callback handler. It means that the last handler remembered by the custom control was cleanUpControl's handler which only throws an error. Functions setUpControl and cleanUpControl can be found in `@angular/forms/src/directives/shared.js`

202,680,143 | rust | [rustdoc] Placeholder for search field makes no sense | Currently `rustdoc` generated documentation has this for the placeholder of search field:
> Click or press 'S' to search, '?' for more options…
Now, the problem here, to summarize, is that this placeholder is not really a placeholder, but rather a call-to-action, half of which is even a feature unrelated to search. Not only this call-to-action won’t be visible with text alraedy entered, it does not really help with identifying the purpose of the field.
I realised this when got to a windows machine for some screen reader tests (for https://github.com/rust-lang/rust/pull/39246) and had the placeholder read out to me. Screen reader, when focused on the field read out:
> Click or press S to search, ? for more options editable field
and I realised that this placeholder doesn’t make sense even when I’m able to see the page, much less when I don’t.
I quickly prototyped a potential change and filled this issue so anybody with better ideas could chime in. | T-rustdoc,C-enhancement | low | Major |

##### Detailed description
We use cv::ogl::Texture2D::copyFrom() to convert an OpenGL texture (depth + stencil) to an ogl::Texture2D, then convert back using cv::ogl::Texture2D::copyTo(). The stencil in the resulting OpenGL texture gets corrupted. The corruption really seems to be in these functions, since we don't do anything on the cv::ogl::texture2D between the two conversions.

##### Detailed description
There is a bug in the Imgproc.Sobel() implementation in OpenCV Manager for Android.
If called with parameters: dx = 1, dy = 0, the function wrongly returns the same result as if it was called with dx = 0, dy = 1.
##### Steps to reproduce
<!-- to add code example fence it with triple backticks and optional file extension
```.cpp
// C++ code example
```
or attach as .txt or .zip file
-->
Compiling this code, and NOT linking the OpenCV library statically, and using the OpenCV Manager App on Android, will result in these two lines giving exactly same results.
```.java
Mat gradX = new Mat();
Mat gradY = new Mat();
Mat gray = new Mat();
Mat gradient = new Mat()
Imgproc.cvtColor( cameraSnapshotFrame, gray, COLOR_BGR2GRAY );
Imgproc.Sobel( gray, gradX, CV_32F, 1, 0, -1, 1.0, 0 );
Imgproc.Sobel( gray, gradY, CV_32F, 0, 1, -1, 1.0, 0 ); // for some reason this gives the same result as the line above
Core.subtract( gradX, gradY, gradient );
Core.convertScaleAbs( gradient, gradient ); // gradient is an empty black image
```
If the usage of OpenCV Manager is dropped, and the library is linked statically within the project, then the issue disappears (the calls produce differing gradients). | wontfix | low | Critical |

202,864,655 | TypeScript | Diagnostic about "left-hand side of a 'for...in' statement" type is out of date | **TypeScript Version:** 2.1.5
Now that the left side of a 'for...in' statement is apparently allowed to be `keyof` the right side, the diagnostic for when the left side has the wrong type needs to be updated to account for that possibility.
(Aside: Is it intentional that the left side won't be _inferred_ to have the `keyof` type because of the unsoundness described in #12314, but it is allowed to be _explicitly declared_ as that type?)
**Code**
```ts
interface Foo {
x: number;
y: string;
}
function scan(f: Foo) {
let k: number;
for (k in f) { // Error: "The left-hand side of a 'for...in' statement must be of type 'string' or 'any'."
console.log(k);
}
let k2: keyof Foo;
for (k2 in f) { // No error
console.log(k2);
}
}
```
**Expected behavior:**
Something like "The index type of the right side of a 'for...in' statement must be assignable to the left side" perhaps, with details on the failure of assignability?

202,902,890 | angular | RouterModule does not initialize correctly when using UpgradeModule | **I'm submitting a ...**
```
[x] bug report
[ ] feature request
[ ] support request
```
**Current behavior**
`initialRouterNavigation` (from [upgrade.ts](https://github.com/angular/angular/blob/master/modules/%40angular/router/upgrade.ts)) is not called during bootstrap. As a consequence, RouterModule does not navigate to the initial URL, and does not subscribe to location changes caused by `ngRoute`, causing it to not deactivate a route when navigating to a route managed by `ngRoute`.
**Expected behavior**
`initialRouterNavigation` is invoked, the RouterModule navigates to the initial URL, subscribes to location changes caused by `ngRoute` and deactivates the current route when `ngRoute` changes location.
**Minimal reproduction of the problem with instructions**
I have been trying to follow the approach documented at [@angular/router/upgrade.ts](https://github.com/angular/angular/blob/master/modules/%40angular/router/upgrade.ts):
main.ts:
```
platformBrowserDynamic().bootstrapModule(AppModule).then(platformRef => {

const upgrade = platformRef.injector.get(UpgradeModule) as UpgradeModule;
upgrade.bootstrap(document.body, ['angularschulung'], {strictDi: true});
});
```

202,908,272 | flutter | iOS transition from standard status bar to expanded status bar is janky | In flutter/engine#3357, we corrected the top padding applied to account for double-height status bars on iOS. While this fix ensures the padding is correct, the transition between a standard height status bar and the expanded, double-height status bar is still janky.
To repro:
1. Start up a Flutter app (e.g., the gallery example) in the iOS simulator.
2. Enable Slow Animations (Cmd-T). This makes what's going on a bit more obvious.
3. Toggle the expanded status bar (Cmd-Y).
It looks like what's happening is:
1. We get the status bar resize event before the transition starts, and the engine sees the view as being 20px shorter.
2. With the view still the full display height, we re-layout the view with the new reduced height, which results in a momentary vertical *stretch* of the view contents.
3. iOS animates some kind of interpolation on the view which results in the view appearing to get *squished*.
Looking at individual widgets at the end of the transition, it looks to me like they might all have actually moved 20px down as desired. It would be nice if we could disable the default iOS transition animation and handle this smoothly.
The code in question is in [FlutterViewController::viewDidLayoutSubviews](https://github.com/flutter/engine/blob/master/shell/platform/darwin/ios/framework/Source/FlutterViewController.mm#L344). | platform-ios,framework,engine,a: fidelity,a: quality,P3,team-ios,triaged-ios | low | Major |

fn fun2(&self);
fn fun3(&self) {}

impl Trait for () {
fn fun2(&self) {}

0000000000015e90 dead::__test::main::h824aaf01f68ecd0a
```
We can observe that that only `fun0` and `<() as Trait>::fun2` is included (also checked with `nm` and running `kcov`). Not including `fun1` and `Trait::fun2` makes code coverage inflates (using `kcov`).
I can see that `fun1` and `Trait::fun2` is not included because they need to be monomorphised. One partial solution would be to monomorphise the default methods implementations for every type that implements the trait, but I think this could blow the binary size and compilation time.
Would it be possible to add this symbols without monomorphisation? Or maybe creating a monomorphised version that just panics? (Could all generic paramaters be set to `!`?)

This makes it impossible to round trip the disassembly (GNU as will not be able to assemble `je .-0x80` into two-byte short jump.)
```
package main

```
However, in AT&T syntax, `.` means the address of the current instruction, whereas the encoding actually means (conditional) jumps to the address of next instruction - 0x80.
I think to better test the disassembler, we need to do round-trip test (disassemble -> use GNU assembler to assemble the instruction -> disassemble again and verify the two Insts are deep equal.)
I want to fix this issue, but the current behavior is locked down the the current testdata/decode.txt.
Should I change the data?

Not sure if it is the right and if not please accept my apology. I am trying to download a video from this url : http://www.styleheroine.com/2017/01/11/valentino-pre-fall-live/
When i inspect the source of the page i found this :
```
<video data-html5-video="" poster="//deb5pi665ie8w.cloudfront.net/video-thumbnails/production_1610_1727_poster.caa.jpg" preload="metadata" src="blob:http://embed.blivenyc.com/6c6c4a70-4729-441c-b95f-3306975c1653"><style class="clappr-style">[data-html5-video] {
position: absolute;

```
The source of the video is a blob URL. I searched the internet to learn that "A blob: URL does not refer to data the exists on the server, it refers to data that your browser currently has in memory, for the current page."
I tried to download the video by launching in the terminal and the result was :

My request is not about supporting this URL but rather to learn more about blob url, how to write a piece of code to download blob url videos. As inspecting the network traffic i found that the video is sent into chunks of ts files i guess the code would be : fetch these chunks and stitch them using ffmpeg.

**Expected behavior:**
Intellisense should display all available options.
For example:
$elementMatch
$in
**Actual behavior:**
Intellisense does not offer anything.

203,454,418 | go | proposal: sync: support for sharded values | Per-CPU sharded values are a useful and common way to reduce contention on shared write-mostly values. However, this technique is currently difficult or impossible to use in Go (though there have been attempts, such as @jonhoo's https://github.com/jonhoo/drwmutex and @bcmills' https://go-review.googlesource.com/#/c/35676/).
We propose providing an API for creating and working with sharded values. Sharding would be encapsulated in a type, say `sync.Sharded`, that would have `Get() interface{}`, `Put(interface{})`, and `Do(func(interface{}))` methods. `Get` and `Put` would always have to be paired to make `Do` possible. (This is actually the same API that was proposed in https://github.com/golang/go/issues/8281#issuecomment-66096418 and rejected, but perhaps we have a better understanding of the issues now.) This idea came out of off-and-on discussions between at least @rsc, @hyangah, @RLH, @bcmills, @Sajmani, and myself.
This is a counter-proposal to various proposals to expose the current thread/P ID as a way to implement sharded values (#8281, #18590). These have been turned down as exposing low-level implementation details, tying Go to an API that may be inappropriate or difficult to support in the future, being difficult to use correctly (since the ID may change at any time), being difficult to specify, and as being broadly susceptible to abuse.
There are several dimensions to the design of such an API.
`Get` and `Put` can be blocking or non-blocking:
* With non-blocking `Get` and `Put`, `sync.Sharded` behaves like a collection. `Get` returns immediately with the current shard's value or nil if the shard is empty. `Put` stores a value for the current shard if the shard's slot is empty (which may be different from where `Get` was called, but would often be the same). If the shard's slot is not empty, `Put` could either put to some overflow list (in which case the state is potentially unbounded), or run some user-provided combiner (which would bound the state).
* With blocking `Get` and `Put`, `sync.Sharded` behaves more like a lock. `Get` returns *and locks* the current shard's value, blocking further `Get`s from that shard. `Put` sets the shard's value and unlocks it. In this case, `Put` has to know which shard the value came from, so `Get` can either return a `put` function (though that would require allocating a closure) or some opaque value that must be passed to `Put` that internally identifies the shard.
* It would also be possible to combine these behaviors by using an overflow list with a bounded size. Specifying 0 would yield lock-like behavior, while specifying a larger value would give some slack where `Get` and `Put` remain non-blocking without allowing the state to become completely unbounded.
`Do` could be consistent or inconsistent:
* If it's consistent, then it passes the callback a snapshot at a single instant. I can think of two ways to do this: block until all outstanding values are `Put` and also block further `Get`s until the `Do` can complete; or use the "current" value of each shard *even if it's checked out*. The latter requires that shard values be immutable, but it makes `Do` non-blocking.
* If it's inconsistent, then it can wait on each shard independently. This is faster and doesn't affect `Get` and `Put`, but the caller can only get a rough idea of the combined value. This is fine for uses like approximate statistics counters.
It may be that we can't make this decision at the API level and have to provide both forms of `Do`.
I think this is a good base API, but I can think of a few reasonable extensions:
* Provide `Peek` and `CompareAndSwap`. If a user of the API can be written in terms of these, then `Do` would always be able to get an immediate consistent snapshot.
* Provide a `Value` operation that uses the user-provided combiner (if we go down that API route) to get the combined value of the `sync.Sharded`.

I'm assuming this is non-trivial to do, but I wish that gettxout could return data for spent outputs. This would allow me to compute, for example, the height at which any transaction was mined. Currently, this is only possible if the transaction in question has one or more unspent outputs due to the current restriction on gettxout.

203,529,178 | angular | Support arrow functions in template syntax | It's not uncommon for a component to take as input a transformation function or predicate function.
For example, [this PR for `@angular/forms`](https://github.com/angular/angular/pull/13349) adds an `@Input` for a predicate function for determining if two options in a `<select>` are equal. Right now, this looks something like:
```
<select [compareWith]="equals" [(ngModel)]="selectedCountries"> ...
equals = (a: Country, b: Country) => {
return a.id === b.id;
};
```
With this feature, this could be written as
```html
<select [compareWith]="(a, b) => a.id == b.id" [(ngModel)]="selectedCountries"> ...
```
There are other places in Angular Material where we're looking to add similar API, e.g., datepicker with something like:
```html
<md-datepicker [allowedDateFilter]="d => isWeekend(d)">
```
Or autocomplete, where the component needs to take an arbitrary value and know what string to write into the text input:
```html
<md-autocomplete [displayWith]="value => value.getFullName()">
```
This would have to account for:
* Functions with multiple arguments (`(a, b) => a + b`)
* Functions with param names that already exist in the context (`<my-x #x [uniq]="x => x.id">`)
* Functions that return an object literal (`x => ({name: x})`)
* Invoking functions on the context (`x => isActive(x)`
* Passing functions through a pipe (`x => x.activate() | debounce`)

I think the downward API should support exposing the node labels on which the pod it is running. While I understand that the Pod should not be coupled too much with the node it is scheduled to. But I think there are certain scenarios that require the pod to have more information about it's host.
- ***failure-zones*** like rack names on premise or availability zones in cloud
- ***instance-types*** for adapting thread settings per instance type
- other labels like local ssd storage available
This helps applications that are cloud-native to understand where they are located. While this could be achieved using API calls to the node object, I think it should be supported by the downward API. A node object would expose way more information that should not be available to any pod. In OpenShift's default configuration there is access to the Node objects prevented by default.

Just trying to pull down some songs from local bands that no longer have their music published. This is using the 'new' MySpace, and occurs when using just the profile URL, /music, and /music/songs. Basically, any MySpace URL doesn't seem to work.
I'm using the following URLs:
https://myspace.com/redlightgreenlight123/music/songs/
https://myspace.com/loveyoumaidthebutcher/
https://myspace.com/knifetheglitter/
https://myspace.com/myonlyescapex/
Edit : I do want to point out, it seems that when youtube-dl attempts to detect headers it's not picking up this is Myspace and tries parsing through the URLs through a generic function; I'm assuming how MySpace handles their media is different than most typical providers hence the issue. | request | low | Critical |

203,734,494 | go | cmd/compile: optimize Write([]byte(stringVal)) to not copy the string | It would be nice to optimize `Write([]byte(stringVal))` to not copy the string value. This is normally safe because most `Write` methods do not modify the byte slice passed in. In fact, the documentation for `io.Writer` requires that the `Write` method not modify the byte slice, although this is not (and can not be) enforced.
Here is how we can do this.
For each function and method that takes a parameter of slice type, record whether the slice's underlying array is modified. This will require generating annotations similar to the ones we generate for escape analysis. Assembly functions will require an annotation similar to //go:noescape. (Naturally, a slice that escapes must be treated as modified.)
For each call of the form `F([]byte(stringVal))`, where we know that `F` does not modify the slice, we can pass the string value directly. This would do essentially the same thing as the existing optimization for map lookups in which a `[]byte` is converted to a `string`. This fixes direct calls, but of course the interesting cases all involve calls to methods of values of type `io.Writer`.
For any type with a `Write` method that does modify the slice, generate at compile time an additional `Write·2` method that makes a copy of the slice and then calls the `Write` method. The method is named `Write·2` to ensure that it does not conflict with any user written method.
When converting any type to `io.Writer` (or any interface type that inherits from `io.Writer`), check for the presence of a `Write·2` method. If that method exists, add it to the interface as an additional entry in the itab.
For any call to an interface method `Write([]byte(stringVal))`, modify the call to call a special function `doWrite` in the io package, without copying the string. `doWrite` will check for a `Write·2` method, and call it if it exists; that will cause the string to be copied as happens today. If the `Write·2` method does not exist, which will be the normal case, `doWrite` will call the `Write` method as usual, knowing that the `Write` method does not modify the slice.
Generalizing this to other methods is left as an exercise for the reader. | Performance,compiler/runtime | medium | Major |

By way of comparison, an analogous C program compiled with GCC takes 4.6s to compile without optimization, or 5.6s with optimization. Python parses and runs an analogous program in 1.2s. So, 45s seems excessive for an unoptimized compile, and 45m+ seems wildly excessive for an optimized compile.

### The issue
Using "encoding/asn1" it is not possible to marshal into a an asn1 general string. It is possible to unmarshal from one but it is only possible to marshal into one of ia5, printable or utf8.

### Suggestion
There should be an struct tag such as "generalstring" that works in the same way as the "ia5" tag but sets the asn1 tag value of 27.

### Issue
I need to be able to marshal into a slice of strings and to be able to specify the string types for the elements in this slice (is5, generalstring, etc)
https://play.golang.org/p/l5id74lMoI
Issue seems to be two fold:
1) Validation does not allow it and you get the error: explicit string type given to non-string member
2) Strings would all be marshaled as the default type - PrintableString
### Suggestion
When struct tags for string types are defined against a slice this should be accepted if the slice is of strings
The struct tag for the string type should be passed down to the marshaling of the members of the slice
