Troubleshooting of Jenkins upgrade to 2.42 JUnit test report
Jenkins 2.39 upgrade to Jenkins 2.42 with an error during build.
Recording test results
ERROR: Step ‘Publish JUnit test result report’ failed: No test report files were found. Configuration error?
Finished: FAILURENo changes have been made during this period, except to upgrade the local gradle from 2.11 to Gradle 3.3
Go to the project configuration selection and find the red prompt.
According to Jenkins:
'build/test-results/*.xml' doesn't match anything: 'build' exists but not 'build/test-results/*.xml'
Fileset ‘includes’ setting that specifies the generated raw XML report files, such as ‘myproject/target/test-reports/*.xml’. Basedir of the fileset is the workspace root.Modified the Settings format by
build/test-results/*.xmlInstead of
build/test-results/**/*.xmlRebuild and pass.

Istio Error 503 upstream connect error or disconnect/reset before headers. reset reason: connect
Error description:
each time you upgrade the microservice (update the microservice version), there is a period of time when the visitor reports 503. istio-proxy + connect error or disconnect/reset before headers.
Reason:
Kubernetes detects Pod readiness (Running status) when a container in the Pod is ready. But once Istio is deployed, the first Pod ready is the istio-proxy container. istio-proxy receives the traffic and finds that upstream microservice has not been started, so istio-proxy will return 503.
The solution:
once you know why, the idea is simple. Just tell Kubernetes that Pod is ready after all the containers in the Pod have been started. Adding readinessprobes to other containers in Pod allows Kubernetes to confirm that the container is ready before forwarding the traffic. As added in the Pod template
livenessProbe:
httpGet:
path: /healthz
port: 80
httpHeaders:
initialDelaySeconds: 10
periodSeconds: 3

updated 1 package in 15.117sThe answer from the stupid network was to remove Node-gyp, so I went with RM-RF node-gyp, killing the entire Node-gyp directory
When it was executed again, another mistake was made:

PHP Error Object of class mysqli could not be converted to string in
An object of class mysqli_result cannot be converted to a string
Check the code:
function query($sql){
echo $sql;
$query = mysqli_query(self::$con,$sql)or die(mysqli_error(self::$con));
return $query;
}Mysqli_result is returned by mysqli_query, so the error should be on the return value.
You cannot directly output an object as a string in PHP5 above.
So just change the type of the return value.
function query($sql){
echo $sql;
$query = mysqli_query(self::$con,$sql)or die(mysqli_error(self::$con));
return mysqli_fetch_array($query);
//return $query;
}Returns as an array with the mysqli_fetch_array() function.

The problem could occur in two situations,
1. No SRC directory was created in the root of the project
2. Check if webpack.config.js is in the root directory
My reason is that I put Webpack.config. js under SRC

WebView loadrequest request request error “nsurlconnection finished with error – Code – 1022”
Execute the following code
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.bing.com"]]];WebView didFailLoadWithError:(UIWebView *)webView didFailLoadWithError:(NSError *)error printed as follows
1 [6587:75627] NSURLConnection finished with error - code -1022
2 [6587:75574] Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy
3 requires the use of a secure connection." UserInfo={NSUnderlyingError=0x600000641f50

The solution is simple:
URLString must use HTTPS to request the WebView to display properly
But then I found out that I had to load http://localhost:8080 and then, sadly, I’m going to have to look at the mechanics, and in XCode 9 I’m going to get an error message that’s pretty obvious
The resource could not be loaded because the App Transport Security policy

Today came to client companies, an employee suddenly told me that her computer has a problem, I hurriedly in the past to see, found that the problem of the specific situation is as follows: normal operation of the computer, all procedures can be normal open closed, but when open a folder on a network drive appeared abnormal, click on the folder will pop up an Error dialog: the Runtime Error C: \ Windows \ explorer exe…
a very strange problem, open folder prompt this error. Without any idea, I have no choice but to turn to Google and Baidu for help. The search results generally have the following solutions:
1. Turn off Internet options — advanced — enable third-party browser support (uncheck the preceding check);
2. Scan for viruses, trojans, malware, useless plug-ins and so on;
3. Error caused by folder preview problem: (CMD – run – regsvr32 /u shmedia. DLL can solve runtime error program: C:\ Windows \explorer.exe)
4. Disk problems, resulting in Visual C++ problems, so prompt error, can my computer – C disk – right – properties – tools – error checking – start checking (may prompt restart to check the disk)
5. Search Microsoft’s official forum to get an answer to a related question:
Download an run ShellExView ( http://www.nirsoft.net/utils/shexview.html) and disable all NON Microsoft Shell extensions! If it’s fixed, try to enable them 50:50 until you find out which extension causes the issue.
finally, after trying the first four solutions, the problem was still unresolved, so I fluked the fifth solution and used ShellexView. After checking all Shell Extensions, some non-Microsoft plug-ins (such as PDF and CAD) were selectively disabled, and the Runtime Error was not reported again.
