curl mydb/_changes?feed=continuous disconnects after about 20 seconds - ibm-cloud

Based on the API reference, the continuous parameter will keep the connection open. However, the following curl command returns after about 20 seconds, which seems not true according to the API reference. Could anyone explain this? Thanks.
curl https://cloudant-URL-bluemix.cloudant.com/mydb/_changes?feed=continuous --http1.1
Returns:
"last_seq":"11-g1AAAAYeeJy11M1NwzAUB3DTIiFOdAM4wLElbpzYPtENYAPw84dKlaYItWfYADaADWAD2AA2gA3KBsWuEampSpIiLo4UWb9_3nt2MoRQq99U6ECBHF3qngIcdWDYlrKtRNaO4o7MRhMl8nEn1-PMbm8IBDuz2WzQb4qNoX2xRSQXkkZVERe3_70zLUmDll1h9ysQzQM5JEaBDdye5Eqb81yrEE3K0D2HHgYoIZIow1ej3TI0cuhRiBolKFtCa3Qbek49DlXNmDB69afSMvTEoacBGiexTDX9Q1PPHDoKUYkBuuSX-nGZeuHUq-DAqTQ2WsRVnZodzzftiq7tw4beuNTGPFXTLgCV_3PMfeitD70rQqXAnLGkIlVvYD7z3mc-FEMTmCjtCl33Jnj40cNPDm76YjTXkUgrUmuN7dmHvhTVUA1M8KUjWHc0rx5-W7iF1EQGx-tfGA-_e3hazJwTLhmBitSPNlWbzYcPXfyncqmxYovVDD4Bc-fgbg","pending":0}

Try:
curl 'https://cloudant-URL-bluemix.cloudant.com/mydb/_changes?feed=continuous&heatbeat=1000'
It's probably timing out if there are no changes to report on. See

How to get the response and logs of a Jenkins test without using the interface, from command line using curl?

I am using curl command to build a job in Jenkins:
curl --user "admin:passwd" -X POST http://localhost:8080/job/jobname/build
How can I check if the test was successful or failed and how to get the logs of that build from command line only, preferably using curl?
If you have BlueOcean plugin installed, you can query its API. This usually returns JSON output that you might need to question further.
First, you need to find the build number triggered by your curl command. Then, you need to wait until your build is over. Then, you can question the result.
A good start is:
"curl -s ${your_jenkins}/blue/rest/organizations/jenkins/pipelines/${jobname}/runs/${buildbumber}/nodes/?limit=10000"

Difference in the HTTP Response code is getting observed when executing a POST call from cURL vs Postman for the same negative test condition

Correct URI: https://example.com/a/b/users/111/c
Negative test URI: https://example.com/a/b/users/<111>/c
Sample Request Body:
{
"abc": "xyz"
}
Postman returned 404 with a message that the user doesn't exist, for the negative test URI mentioned above.
Then I executed the cURL generated by the Postman and appended to it "-k" to ignore the certificate verification and "-v" for verbosity. However, cURL returned 500 for the same URI.
The original concern was that there has been a mismatch in the test results when the above API was hit by an automation test using RestAssured vs when manually executing it from Postman. Debugging that has led me to find out the difference in response between Postman and curl as well.
Any thoughts to debug this issue further?
While debugging, I found the URI passed was getting encoded and decoded, and <111> got printed as %3C111%3E at one of the breakpoints. So when I tried sending the encoded URI from cURL like https://example.com/a/b/users/%3C111%3E/c it worked just fine returning 404. However Postman returned 404 both with <111> and %3C111%3E.
Thanks to #derpirscher for providing hints that helped me reach this conclusion.
P.S. For more details, please refer my last comment above.

Unable to import test results to jira via rest api

i'm using the following curl command to import the output.xml file into jira test execution key and receiving error as below. I'm sure the test execution key is existing in jira and the project id is also correct. Any pointers?
curl -H "Content-Type: multipart/form-data" -u userid:pass -F "file=#output.xml" "https://server/rest/raven/latest/import/execution/robot?projectKey=PROJKEY+and+testExecKey=TESTEXNKEY" -o error.txt
The error i receive is as below
The User "userid" does not have permission to create issues
Why does it try to create new issue while the issue already exists? And why does it say the user doesn't have access when the access is there?
You probably mean Xray add-on and you probably use the same request per their documentation. The problem seems to be with your parameter syntax. It should be .../robot/?projectKey=PROJKEY&testExecKey=TESTEXNKEY (i.e. & instead of +and+).
Plus I would explicitly specify it's a POST request: curl -X POST ....
But their error message is not clear, anyway. I don't have Xray available right now, but if you keep having troubles, I would recommend checking with their support.

Get Jenkins Job Build ID from Queue ID

I'm successfully able to use this to kick off a Jenkins Job:
curl -X POST "http://jenkins_srv:8080/job/MY_JOB/buildwithParameters?this=1&that=2" --user name:pass
I can also get the consoleText from this job using:
curl -X POST "http://jenkins_srv:8080/job/MY_JOB/lastBuild/consoleText"
However, this doesn't scale if I run multiple jobs back to back. I've noticed that the first curl command has a return that includes:
Location: http://jenkins_srv:8080/queue/item/123/
I'm assuming that 123 is the job queue id.
My question is, if I queue jobs 121, 122, & 123 back to back, what do I use to check the status of job queue item 122? Also, what do I use to determine the actual build id that eventually resulted from job queue item 122?
I chose Kdawg's answer, because it helped lead me in the direction that I needed. Thank you!
I'm also including my own answer, because the solution I implemented was different than Kdawg's answer, and I feel it will add value for other people.
First off, I'm new to Jenkins. So if I misspeak, please feel free to correct me. Second, I had a slight learning curve in that there is a difference between a Jenkins "queue item" and a Jenkins "build job". The instant that a "queue item" has been created, there is no "build job" ID, because no build job has started. Also, once a build job has started, the queue item has 5 minutes before it is deleted.
When I perform these tasks:
curl -X POST "http://jenkins_srv:8080/job/MY_JOB/buildwithParameters?this=1&that=2" --user name:pass
curl -X POST "http://jenkins_srv:8080/job/MY_JOB/buildwithParameters?this=1&that=2" --user name:pass
curl -X POST "http://jenkins_srv:8080/job/MY_JOB/buildwithParameters?this=1&that=2" --user name:pass
Jenkins will schedule 3 build jobs to be run in a queue. These will be "queue items". These "queue items" will have a "Queue ID". In the example given in my original question, lets suppose that these three curl commands create "queue items" with "Queue ID"s 121, 122, & 123.
Why is this important?
Because depending on the load of your Jenkins server, the item that was queued may or may not be run immediately. If it runs immediately, then Kdawg's answer is definitely correct. Running his commands:
curl -X GET http://jenkins_srv:8080/queue/item/121/api/json?pretty=true --user name:pass
curl -X GET http://jenkins_srv:8080/queue/item/122/api/json?pretty=true --user name:pass
curl -X GET http://jenkins_srv:8080/queue/item/123/api/json?pretty=true --user name:pass
This will get queue information about each "queue item", and in what returns, there is definitely a way to obtain a "build job" ID, if the build job has started. If a build job has not yet started, this information will be blank.
Here's the additional part that, I feel, adds value.
Once a build job has started, the information in Kdawg's answer will be populated in the response to the three curl -X GET commands. Also, by default, Jenkins is designed to scavenge (garbage collection, choose your own term) the "queue item"s every 5 minutes. So in other words, if all you have is a "queue item" ID and the 5 minute data retention window passes, then you need another mechanism in order to get a "build job" ID from a "queue item" ID.
So, in my case, I'm using Jenkins as a front end, and Ansible on the back end to perform server configuration and application deployments. Some of these application deployments can take 30 minutes or more, well beyond the 5 minute data retention period of the "queue items".
So the problem that I had to solve, if all I have is a "queue item" ID, then how do I find a "build job" ID, regardless of when I'm checking, seconds later or hours later?
Here was my solution (Note that I required XML output, FYI).
I ran this command:
curl -X POST "http://jenkins_srv:8080/job/MY_JOB/buildwithParameters?this=1&that=2" --user name:pass
This command would return this information:
Runtime responseHeaders Date: Day, ## Non Year xx:yy:zz GMT
X-Content-Type-Options: nosniff
Location: http://jenkins_srv:port/queue/item/123/
Content-Length: 0
Server: Jetty(9.4.z-SNAPSHOT)
From here, I can parse out 123 from the Location field.
I then slept for 10 seconds. After the sleep, I run this command on a 10 second loop:
curl -X GET http://jenkins_srv:8080/queue/item/123/api/xml
I did that until I either:
I got a queue item return that included the xpath //executable/number that's shown in Kdawg's example, or
I got HTML 404 status code for more than 10 minutes, meaning the job hasn't been queue'd yet or I passed the 5 minute data retention window.
The loop in this way handles a burdened Jenkins server that's sluggish on handling queue requests. So presumably if I get to the end of 10 minutes, then my approach will still handle the use case that my automation approach has successfully queue'd and run the job, but it's checking Jenkins outside the data retention window. In this case, I would run this command:
curl -X GET http://jenkins_srv:port/job/MY_JOB/api/xml?tree=builds[id,number,result,queueId]&xpath=//build[queueId=123]
This returns the XML info for any "build job" that also contains a queueId of 123, as shown below:
<?xml version="1.0"?>
<build _class="hudson.model.FreeStyleBuild">
<id>456</id>
<number>456</number>
<queueId>123</queueId>
<result>SUCCESS</result>
</build>
In this way, I was able to authoritatively get a "build job" ID while only having a "queue item" ID regardless of the time difference between when I started and when I checked back.
Assuming that you have a location of http://jenkins_srv:8080/queue/item/123/, you can GET http://jenkins_srv:8080/queue/item/123/api/json?pretty=true to return information about that queue item (you can also not include ?pretty=true if you don't care about formatting, or use api/xml if you want the results in XML).
I don't know if there's standard documentation on the queue API, but it appears that if the queue item has completed (maybe also if it's currently being built?) it will have an executable node. One for my server looked like this:
"executable" : {
"_class" : "org.jenkinsci.plugins.workflow.job.WorkflowRun",
"number" : 10,
"url" : "http://192.168.99.100:32769/job/configure/10/"
}
You can then GET the API for the URL specified in executable.url. In my case, GET http://192.168.99.100:32769/job/configure/10/api/json?pretty=true. From there, you should have all the information you need, including whether or not the build is currently being built, how long the build took/has taken, the result, etc.
Also, if you want information on your entire build queue, you can GET http://jenkins_srv:8080/queue/api/json?pretty=true
Astonishing that Jenkins doesn't track a request to its conclusion with a unique ID.
One element that persists between the queued item and the build item is the list of parameters. If you have the ability/authority to change the config of the jobs, then add an optional parameter REQUEST_ID that the client plucks from the air (e.g. a UUID) and passes in over REST. Then you can quiz the queue and look for the one with your REQUEST_ID, and you can quiz the list of builds and look for the one with your REQUEST_ID.
There's an interesting thing about this that if you want to queue multiple builds in the loop, you might end up getting SAME QUEUE_ID, This happens especially when you have the same parameter and queued builds have not started up. Basically, Jenkins assumes that you are just trying to build this and instead of multiple builds it just assumes that it needs to spin up only a single build, hence the SAME QUEUE_ID, To overcome this, if you add an extra parameter while building the job like UQ_ID=CURRENT_TIMESTAMP (This param doesn't need to be in build) then you will get the unique build number
If there's no param at all in the build you should define at least one param, Because parameterless build won't allow ANY parameter to be passed in the api
you can fetch job details by id
http://localhost:8080/job/{jobName}/{jobId}/api/json
curl --location --request GET 'http://localhost:8080/job/testPipeline/2/api/json' \
--header 'Authorization: Basic 1234' \

Cannot set more than one Meta data with OpenStack Swift Object

I am trying to set metadata with a Object stored in Swift Container. I am using following command (note that my container is 'container1' and object is 'employee.json':
curl -X POST -H "X-Auth-Token:$TOKEN" -H 'X-Object-Meta-metadata1: value' $STORAGE_URL/container1/employee.json
It works fine with one metadata. But whenever, I am trying to set more than one metadata issuing several curl commands, only the last metadata value is actually set.
I think, there should not be a limit that you can set only one metadata for a swift object. Am I doing anything wrong?
FYI: I am using Havana release of Openstack Swift.
Thank you.
I think, I have figured it out... Its my bad that I did not read documentation sincerely.
It [1] says, "A POST request will delete all existing metadata added with a previous PUT/POST."
So, I tried this and it worked...
curl -X POST -H "X-Auth-Token:$TOKEN" -H 'X-Object-Meta-p1:[P1]' -H 'X-Object-Meta-p2:[P1]' $STORAGE_URL/container1/employee.json
Here, instead of two POST requests, now I have set multiple metadata in a single POST request.
Again, thanks.
