Use mongorestore to restore a database to MongoDB (3.4) with --auth enabled, SASL error : <p>Using mongorestore, I am trying to restore a MongoDB database to a new server (both version are 3.4). The new server has -auth enabled, so you are required to login. The database does not exist so I want mongorestore to create it using the --db option. This works when authorization is not enabled but if I enable authorization the restore fails with the following error:</p>
<p>Failed: error connecting to db server: server returned error on SASL authentication step: Authentication failed.</p>
<p>I am using an admin account with the root role when I attempt the restore.</p>
<p>Backing up prod and restoring to dev is a fairly regular activity for us, but we can't just drop the existing database and recreate it because of the error above, not unless we disable authorization which doesn't make much sense. Is there a better way to do this/avoid the SASL errors/not have to disable auth?</p>

python calling a module that uses argparser : <p>This is probably a silly question, but I have a python script that current takes in a bunch of arguements using argparser and I would like to load this script as a module in another python script, which is fine. But I am not sure how to call the module as no function is defined; can I still call it the same way I do if I was just invoking it from cmd?</p>
<p>Here is the child script:</p>
<pre><code>import argparse as ap
from subprocess import Popen, PIPE
parser = ap.ArgumentParser(
description='Gathers parameters.')
parser.add_argument('-f', metavar='--file', type=ap.FileType('r'), action='store', dest='file',
required=True, help='Path to json parameter file')
parser.add_argument('-t', metavar='--type', type=str, action='store', dest='type',
required=True, help='Type of parameter file.')
parser.add_argument('-g', metavar='--group', type=str, action='store', dest='group',
required=False, help='Group to apply parameters to')
# Gather the provided arguements as an array.
args = parser.parse_args()
... Do stuff in the script
</code></pre>
<p>and here is the parent script that I want to invoke the child script from; it also uses arg parser and does some other logic</p>
<pre><code>from configuration import parameterscript as paramscript
# Can I do something like this?
paramscript('parameters/test.params.json', test)
</code></pre>
<p>Inside the configuration directory, I also created an <strong>init</strong>.py file that is empty.</p>

Bitcode bundle could not be generated (while archiving) because Static Framework (.framework) was built without full bitcode : <p>We are trying to enable Bitcode fully in our Static Framework but we are receiving the following error while archiving the app when the framework is integrated with it though we are able to build it on the simulator or device.</p>

Run only the next migration file : <p>Is it possible to run only the next migration file with the sequelize-cli?</p>
<p>I have been looking through the docs and help-section of the cli, and it does not appear to be such a feature.</p>
<p>For instance, I have the following when running the <code>sequelize db:migrate:status</code> command;</p>
<pre><code>Loaded configuration file "config/config.js".
Using environment "development".

down 20170316142544-create-an-index.js
down 20170421112638-do-some-refactor.js
</code></pre>
<p>I would like to only run the <code>20170316142544-create-an-index.js</code>. </p>
<p>Of course, I can remove all the relevant files. Then I add each migration back one-by-one, running "all" migrations between each one. But this seems so barbaric.</p>

The input is of the following form:
13
13
0 5 2.1
4 3 2.3
0 1 3.2
9 12 4.2
6 4 5.1
5 4 2.2
0 2 0.2
11 12 0.22
9 10 0.22
0 6 0.22
7 8 0.22
9 11 0.22
5 3 0.22
I intend to read the first two lines and returns the edges and vertex num in the 'readstruct' function. Line 3 and Line 15 are read in the readIndata function. The code is compling fine using g++. But gives segmentation fault when reading input. I tried to use gdb to debug and found that the code continues to read the file when it reaches line 15(or i=13) in readIndata function.

How to use TypeScript in a Custom Test Environment file in Jest? : <p>I need to enable some global variables to be reachable for my test so I am setting up a Custom Environment to be used in the <code>testEnvironment</code> option in my <code>jest.config.json</code> to achieve that.</p>
<p>For our project we have a TypeScript file that we use for <code>setupFilesAfterEnv</code> option and that works just fine, however the <code>testEnvironment</code> seems to support only ES5. Is there any way to use TypeScript in such option?</p>
<p>I successfully created a Custom Jest Environment using ES5 syntax, however since we are injecting global variables I need TypeScript to also declare a global namespace see: <a href="https://stackoverflow.com/a/42304473/4655076">https://stackoverflow.com/a/42304473/4655076</a>. </p>
<pre class="lang-js prettyprint-override"><code>{
///...
setupFilesAfterEnv: ['<rootDir>/test/setup.ts'], // This works with ts
testEnvironment: '<rootDir>/test/customJestEnvironment.ts', // This doesn't work with ts
}
</code></pre>

Why do i convert map to json, map includes list values which is nothing after converting to json : func Test_JsonTtransfer(t *testing.T) {
uid := "306"
phoneList := list.New()
phoneList.PushBack("18513622928")
fmt.Println("phoneList=======", phoneList.Len())
jsonPhoneList, err := json.Marshal(phoneList)
if err != nil {
fmt.Println("error:", err)
}
fmt.Println("jsonPhoneList=======", string(jsonPhoneList))
idCardList := list.New()
idCardList.PushBack("230405197608040640")
request := make(map[string]interface{})
request["uid"] = uid
request["phones"] = phoneList
request["id_cards"] = idCardList
json, err := json.Marshal(request)
if err != nil {
fmt.Println("error:", err)
}
fmt.Println("json=======", json)
fmt.Println("json=======", string(json))
}
output:

Is there a way of not hard coding sql queries in my express app? : <p>So I am making an express app for a project and I am using mysql as the db, I had previously hard coded my sql queries in my code, but it is bad practice to do so according to my teacher, so I was looking for a way in which I don't have to hard code. </p>
<p>I have tried queries like find and findAll using mongoose, I am looking for something similar.</p>
<pre><code>app.get("/shops/:id",function(req,res){
var id = req.params.id;
connection.query('SELECT * FROM `menuItems` WHERE shop_id =?',[id],function(error,results,fields) {
console.log(results);
res.json(JSON.stringify(results));
})
});
</code></pre>
<p>I don't want to hard code my queries as I have in the above code snippet.</p>
<p>Kindly help me get a way for not hard coding sql queries in my app. Thanks in advance.</p>

How to have multiple goroutines read the lines of a single file? : <p>I want to read a huge file, say > 1 GB, and have its lines processed by multiple worker goroutines.</p>
<p>I'm worried that using a single goroutine (main) for reading the input lines will impose a bottleneck, when using a huge number of worker goroutines.</p>
<p>How can I safely have multiple goroutines read the lines of the file? Is it possible split the input file into several chuncks and have each goroutine operate on a separate chunk individually?</p>
<p>The following is sample code of having one goroutine read input lines with several worker goroutines processing them:</p>
<pre><code>package main
import (
"bufio"
"fmt"
"log"
"os"
)
func main() {
file, err := os.Open("/path/to/file.txt")
if err != nil {
log.Fatal(err)
}
defer file.Close()
lines := make(chan string)
for i := 0; i < 100; i++ {
// start 100 workers to process input lines.
// the workers terminate once 'lines' is closed.
go worker(lines)
}
scanner := bufio.NewScanner(file)
go func() {
defer close(lines)
for scanner.Scan() {
lines <- scanner.Text()
}
if err := scanner.Err(); err != nil {
log.Fatal(err)
}
}()
...

<li>Are there plans to implement TCO in the near future in any Javascript Engine</li>

Sample Projects about the backup of Sqlite file and photos on Google Drive programmatically in Android : <p>I am writting an app with an instant messenger function. Users would write text or share images in the IM function. The <strong>text data and file name of images are stored in the sqlite file while the images are stored in the device</strong>.</p>
<p>Since my server will not keep the data, the <strong>user would not get the chat record when he / she switches to a new device</strong>. With reference to whatsapp, they allow the users to back up the chat records and images to Google Drive on a regular basis and get the data back from the drive as shown in the picture below.</p>
<p><a href="https://i.stack.imgur.com/eTJug.png" rel="noreferrer"><img src="https://i.stack.imgur.com/eTJug.png" alt="enter image description here"></a>
When I go to my own google drive, I would find "Whatsapp" is connected to my google drive as shown below.</p>
<p><a href="https://i.stack.imgur.com/1gPxB.png" rel="noreferrer"><img src="https://i.stack.imgur.com/1gPxB.png" alt="enter image description here"></a>
I am new to the Google Drive API in Android and I would like to backup my sqlite database and images in the same way as Whatsapp does. I know there are few questions related to the back-up of sqlite database to Google Drive but it seems that it only contains part of the codes and this makes the beginner quite difficult to understand.</p>
<p>Will there be any <strong>sample projects</strong> on github, questions on stackoverflow or tutorials that would allow me learn how to <strong>back up sqlite database and images programmatically in Android</strong> step by step?</p>
<p>In additions, I am surprised to see <strong>only whatsapp is connected to my Google Drive</strong> but no more other apps, so I don't know if third-party developers would have the same access to Google Drive and complete the backup in the same way as Whatsapp.</p>

how do i sort variables into other variables by ranking in python : so i am trying to make a program to imrove my python skills which is basically a lucky wheel, you get several items which are all ranked by numbers, i have made the items randomly generate but how would i make them print in order? i assume that the sort() method won't be any use in this situation.
```
# to sort: itemrating1, itemrating2, itemrating3
print(toprateditem)
print(meditem)
print(lowitem)
```
that is basically what i want to do, i hope i explained it well.

Regexp for mentions in html content : I'm trying to do a regexp for catch the mention in a html content.
I have a content like this:
<div data-user-id="@john">@john</div>
I want catch only the mention inside the divs...not inside the "".
I've done this regexp: http://regexr.com/3ckv8 ( /[^"]@[a-zA-Z0-9_]*[^"]/g )
That works almost fine...the problem is that it catch also the >< of the div tags.
Any suggestion ?
Thanks.

Annotation Processor in IntelliJ and Gradle : <p><strong>tl;dr</strong>: I cannot configure IntelliJ to generate the java files in the same directory as gradle</p>
<p>I have a small project which uses the <a href="https://immutables.github.io/" rel="noreferrer">immutables</a> annotation processor.
It works as expected in the gradle command line build, but I cannot get IntelliJ to output the generated files to the same directory.</p>
<p>The full project is available on <a href="https://gitlab.com/tmtron-immutables/encoding/tree/0.0.1" rel="noreferrer">GitLab</a></p>
<p><strong>Gradle config</strong>:<br>
I use the folowing gradle plugins:</p>
<ul>
<li><a href="https://docs.gradle.org/current/userguide/idea_plugin.html" rel="noreferrer">gradle-idea plugin</a> which handles the idea configuration</li>
<li><a href="https://github.com/tbroyer/gradle-apt-plugin" rel="noreferrer">gradle-apt-plugin</a> which provides the apt configuration and handles the compile-class path and idea config related to annotation processing (if also the idea plugin is applied)</li>
</ul>
<p>relevant parts of the build-script (<a href="https://gitlab.com/tmtron-immutables/encoding/blob/0.0.1/build.gradle" rel="noreferrer">link to the full listing</a>):</p>
<pre><code>apply plugin: 'java'
apply plugin: "net.ltgt.apt"
apply plugin: 'idea'
dependencies {
def immutablesVersion = '2.3.9'
compileOnly "org.immutables:value:$immutablesVersion:annotations"
compileOnly "org.immutables:encode:$immutablesVersion"
apt "org.immutables:value:$immutablesVersion"
}
</code></pre>
<p>when I start <code>./gradlew build</code> everything is as expected:
<a href="https://gitlab.com/tmtron-immutables/encoding/blob/0.0.1/build.gradle" rel="noreferrer"><img src="https://i.stack.imgur.com/Es3n0.png" alt="enter image description here"></a></p>
<ol>
<li>The source file <code>DataEncoding.java</code> is processed an the generated java-file <code>DataEncodingEnabled.java</code> ends up in</li>
<li><code>/build/generated/source/apt/main</code> under the expected package <code>com.tmtron.immutables.data</code></li>
<li>and the generated file is also compiled to a .class file</li>
</ol>
<p>In IntelliJ I activate the annotation processing as suggested by the <a href="https://github.com/tbroyer/gradle-apt-plugin#intellij-idea" rel="noreferrer">gradle-apt-plugin docs</a>:
<a href="https://github.com/tbroyer/gradle-apt-plugin#intellij-idea" rel="noreferrer"><img src="https://i.stack.imgur.com/bSSEx.png" alt="enter image description here"></a></p>
<p>Then I execute <code>./gradlew clean</code> to make sure, that the previous files are gone and then I click <code>Build</code> - <code>Build Project</code> in IntelliJ.<br>
The annotation processor is executed, but the problem is that the generated java file ends up in the wrong location:
<a href="https://i.stack.imgur.com/bSSEx.png" rel="noreferrer"><img src="https://i.stack.imgur.com/2sc7u.png" alt="enter image description here"></a></p>
<p>It is in: /build/generated/source/apt/main/<strong>build/generated/source/apt/main</strong>/com.tmtron.immutables.data<br>
the bold part is redundant. </p>
<p>What am I doing wrong and how can I set it up correctly, so that IntelliJ and gradle generate the files in the same directory?</p>
<p>Notes: </p>
<ul>
<li>I have of course already tried to just leave the "Production sources dir" in the IntelliJ annotation configuration empty, but his does not work: then it automatically uses "generated" and I also end up with a wrong path.</li>
<li>IntelliJ version 2016.3.4</li>
</ul>

Why fwrite prints spaces while writing binary file in C? : #include <stdio.h>
struct my_struct{
char text[50];
} e;
int main(){
FILE *file;
file = fopen("filename", "ab+");
if(file == NULL){
file = fopen("filename", "wb+");
}
printf("Input text: ");
fflush(stdin);
gets(e.text);
fwrite(&e, sizeof(e), 1, file);
fclose(file);
return 0;
}
What I'm trying to do here is create a binary file and write the file by text input from the user. The code works fine! The only problem is that the file contains spaces, which I believe is due to the array size of `struct my_structure` that `fwrite` passes while writing the file. I cannot find a good way to remove spaces or replace `fwrite`. Thank you! for answering this question.

How to test styled Material-UI components wrapped in withStyles using react-testing-library? : <p>I am trying to create a test with a styled Material-UI component using react-testing-library in typescript. I'm finding it difficult to access the internal functions of the component to mock and assert. </p>
<p>Form.tsx</p>
<pre><code>export const styles = ({ palette, spacing }: Theme) => createStyles({
root: {
flexGrow: 1,
},
paper: {
padding: spacing.unit * 2,
margin: spacing.unit * 2,
textAlign: 'center',
color: palette.text.secondary,
},
button: {
margin: spacing.unit * 2,
}
});
interface Props extends WithStyles<typeof styles> { };
export class ExampleForm extends Component<Props, State> {
async handleSubmit(event: React.FormEvent<HTMLFormElement>) {
// Handle form Submit
...
if (errors) {
window.alert('Some Error occurred');
return;
}
}
// render the form
}
export default withStyles(styles)(ExampleForm);
</code></pre>
<p>Test.tsx</p>
<pre><code>import FormWithStyles from './Form';
it('alerts on submit click', async () => {
jest.spyOn(window,'alert').mockImplementation(()=>{});
const spy = jest.spyOn(ActivityCreateStyles,'handleSubmit');
const { getByText, getByTestId } = render(<FormWithStyles />)
fireEvent.click(getByText('Submit'));
expect(spy).toHaveBeenCalledTimes(1);
expect(window.alert).toHaveBeenCalledTimes(1);
})
</code></pre>
<p><code>jest.spyOn</code> throws the following error <code>Argument of type '"handleSubmit"' is not assignable to parameter of type 'never'.ts(2345)</code> probably because ExampleForm in wrapped in withStyles. </p>
<p>I also tried directly importing the <code>ExampleForm</code> component and manually assigning the styles, was couldn't do so:</p>
<pre><code>import {ExampleForm, styles} from './Form';
it('alerts on submit click', async () => {
...
const { getByText, getByTestId } = render(<ActivityCreateForm classes={styles({palette,spacing})} />)
...
}
</code></pre>
<p>Got the following error: <code>Type '{ palette: any; spacing: any; }' is missing the following properties from type 'Theme': shape, breakpoints, direction, mixins, and 4 more.ts(2345)</code></p>
<p>I'm finding it difficult to write basic tests in Typescript for <code>Material-UI</code> components with <code>react-testing-library</code> & <code>Jest</code> due to strong typings and wrapped components. Please Guide.</p>

Android Studio: product flavor combination with more than two flavor dimensions (flavor groups) : <p>I am developing an Android application using Android Studio (v 2.1, gradle plugin v 2.1.0). My application has various versions which share a lot of common code so I decided to use flavor dimensions and product flavors to customize code and resources when and where it is requested. This worked fined as long as I only had two flavor dimensions. As an example, my <code>app.gradle</code> was</p>
<pre><code>…
flavorDimensions "fruit", "color"
productFlavors {
apple {
dimension "fruit"
}
pear {
dimension "fruit"
}
red {
dimension "color"
}
yellow {
dimension "color"
}
}
…
</code></pre>
<p>and my <code>src</code> folder was</p>
<pre><code>src/
appleRed/
appleYellow/
pearRed/
pearYellow/
</code></pre>
<p>each one with a custom version of my code. Again, as an example</p>
<pre><code>src/
appleRed/java/com/example/ExampleFragment.java
appleYellow/java/com/example/ExampleFragment.java
pearRed/java/com/example/ExampleFragment.java
pearYellow/java/com/example/ExampleFragment.java
</code></pre>
<p>of course, there is no instance of <code>ExampleFragment</code> in <code>src/main</code>.</p>
<p>At some point during development, I had to include a <em>free</em> and a <em>paid</em> version of the app. I thought that it could be easily achieved by adding a new flavor dimension named <code>version</code> and two product flavors named <code>free</code> and <code>paid</code>:</p>
<pre><code> …
flavorDimensions "fruit", "color”, “version”
productFlavors {
apple {
dimension "fruit"
}
pear {
dimension "fruit"
}
red {
dimension "color"
}
yellow {
dimension "color"
}
free {
dimension "version"
}
paid {
dimension “version”
}
}
…
</code></pre>
<p>but all of a sudden the custom code generated by the combination of <code>fruit</code> and <code>color</code> was not detected by Android Studio anymore. So no <code>appleRed</code>, <code>appleYellow</code>, <code>pearRed</code> nor <code>pearYellow</code> can be used to have custom code and the only way I was able to regain my configuration was to use all the combinations of all the three flavour dimensions:</p>
<pre><code> src/
appleRedFree/java/com/example/ExampleFragment.java
appleRedPaid/java/com/example/ExampleFragment.java
appleYellowFree/java/com/example/ExampleFragment.java
appleYellowPaid/java/com/example/ExampleFragment.java
pearRedFree/java/com/example/ExampleFragment.java
pearRedPaid/java/com/example/ExampleFragment.java
pearYellowFree/java/com/example/ExampleFragment.java
pearYellowPaid/java/com/example/ExampleFragment.java
</code></pre>
<p>This is not good because <code>ExampleFragment</code> is duplicated across the same <code>fruitColor*</code> combination (<code>appleRedFree</code>, <code>appleRedPaid</code> have the same <code>ExampleFragment</code>). Same problem happens for resources (the ones in <code>res</code> folder).</p>
<p>My questions are: </p>
<p>1) Is this the expected behaviour from gradle in Android Studio (<em>i.e.</em>, not being able to combine a subset of product flavors, following their priority based on their dimension, when having more than two flavour dimensions)?</p>
<p>2) Given the fact that this is the expected behaviour, is there another way I can achieve my customisation without duplicated code or without having a single file with an <em>if-statement</em> inside (<em>e.g.</em>, <code>if (BuildConfig.FLAVOR_version == "free") ...</code>) ? </p>
<p>Please note that I’m talking about having custom code which could be complex, so I’m not asking for basic customisation like a build config variable, variant filtering, or something like that.</p>
