How to access Hudson job1 artifacts from another job2? - hudson

We have a production job and a nightly job for a project in Hudson. The production job needs to pull off some artifacts from a specific nightly build # (which is provided as parameter). Can anyone help us with a hint on how to achieve this?

The Copy Artifact plugin seems to be capable of doing this.
Another approach could be to fetch the artifact via
http://server/jobs/job1/[build #]/artifacts/

You can use "Build Environment" configuration tools in the job's configuration page. Tick the Configure M2 Extra Build Steps box and add an Execute Shell which grep things from the desired artifact.

We have similar need and use the following system groovy:
import hudson.model.*
def currentBuild = Thread.currentThread().executable;
currentBuild.addAction(new ParametersAction(new StringParameterValue('LAST_BUILD_STATUS', 'FAILURE')));
def buildJob = Hudson.instance.getJob("ArtifactJobName");
def artifacts = buildJob.getLastBuild().getArtifacts();
if (buildJob.getLastBuild().getResult() == Result.SUCCESS && artifacts != null && artifacts.size() > 0) {
currentBuild.addAction(new ParametersAction(new StringParameterValue('VARIABLE_NAME', artifacts[0].getFileName())));
currentBuild.addAction(new ParametersAction(new StringParameterValue('LAST_BUILD_STATUS', 'SUCCESS')));
}
This creates a VARIABLE_NAME with the artifact name in it from ArtifactJobName, which we use since they are all stored in a specific folder. I am not sure what will happen if you have multiple artifacts, but it seems you could get them from the artifacts array.
You could use getLastSuccessfulBuild to prevent issue when another ArtifactJobName is being build at the moment and you get array with null.

How to get job and telescope command on chrome's V8 x64.release version? (No symbol "_v8_internal_Print_Object" in current context)

I'm trying to get chrome's V8 (d8) x64.release version to use the V8 support tools in GDB, specifically for the job and telescope commands (predominantly the former).
My x64.debug version has this implemented and works, but even after building the x64.release version in a similar manner I still cannot get these commands to work in the x64.release version. The output is always as:
gef➤ job 0xd98082f7b51
No symbol "_v8_internal_Print_Object" in current context.
I have set args.gn before, and after building via ninja -C to include v8_enable_object_print = true in my args.gn:
is_debug = false
target_cpu = "x64"
use_goma = false
v8_enable_object_print = true
v8_enable_disassembler = true
I also have my ~/.gdbinit containing:
source ~/Desktop/tools/v8/tools/gdbinit
source ~/Desktop/tools/v8/tools/gdb-v8-support.py
See: https://chromium.googlesource.com/v8/v8/+/refs/heads/main/tools/gdbinit (for the support tool I'm trying to build V8 with).
How can I get my /v8/out.gn/x64.release/d8 to run with compatibility of the job command?
Am I missing something here? If so your help would be very helpful.
EDIT Alternatively how can I disable all x64.debug V8 DCHECKS?
Thanks all, appreciate your time here.
How can I get my /v8/out.gn/x64.release/d8 to run with compatibility of the job command?
I'm not sure. Try adding symbol_level = 1 (or even symbol_level = 2) to your args.gn. That definitely helps with stack traces, and might also be the thing that lets GDB find the _v8_internal_Print_Object function by name.
Alternatively how can I disable all x64.debug V8 DCHECKS?
There is no flag to disable them, but you can edit the source to make them do nothing. See src/base/logging.h.

Python code in Google Cloud function not showing desired output

I have the following lines of python code
import os
def hello_world():
r=os.system("curl ipinfo.io/ip")
print (r)
hello_world()
Shows the desired output when executed from command line in Google Cloud Shell but seems there is a 0 at the end of IP Address output
$ python3 main2.py
34.X.X.2490
When I deployed the same code in Google CLoud function it is showing OK as output
I have to replace the first line of code in GCF as follows to make it deploy.
def hello_world(self):
Any suggestion so that GCF displays the desired output which is the output of curl command?
Your function won't work for 2 reasons:
Firstly, you don't respect the HTTP Cloud Function Python function signature:
def hello_world(request):
....
Secondly, you can't use system call. In fact not exactly, you can perform system call, but, because you don't know which package/binaries are installed, you can't rely on this. It's serverless, you don't manage the underlying infrastructure and runtime environment.
Here you made the assumption that CURL is installed on the runtime image. Maybe yes, maybe not, maybe it was, maybe it will be remove in future!! You can't rely on that!!
If you want to manage you runtime environment, you can use Cloud Run. You will manage your runtime environment, and you can install what you want on it and then you are sure of what you can do.
Last remarks:
note: instead of performing a CURL, you can perform a http get request to the same URL to get the IP
Why do you want to know the outgoing IP? It's serverless, you also don't manage the network. You will reach the internet through a Google IPs. It can change everytime, and other cloud functions (or cloud run), from your projects or project from others (like me), are able to use the same IPs. It's Google IPs, not yours! If it's your requirement, let me know, there are solutions for that!

How to use the Google api-client python library for Google Logging

I've been using the Google apiclient library in python for various Google Cloud APIs - mostly for Google Compute - with great success.
I want to start using the library to create and control the Google Logging mechanism offered by the Google Cloud Platform.
However, this is a beta version, and I can't find any real documentation or example on how to use the logging API.
All I was able to find are high-level descriptions such as:
https://developers.google.com/apis-explorer/#p/logging/v1beta3/
Can anyone provide a simple example on how to use apiclient for logging purposes?
for example creating a new log entry...
Thanks for the help
Shahar
I found this page:
https://developers.google.com/api-client-library/python/guide/logging
Which states you can do the following to set the log level:
import logging
logger = logging.getLogger()
logger.setLevel(logging.INFO)
However it doesn't seem to have any impact on the output which is always INFO for me.
I also tried setting httplib2 to debuglevel 4:
import httplib2
httplib2.debuglevel = 4
Yet I don't see any HTTP headers in the log :/
I know this question is old, but it is getting some attention, so I guess it might be worth answering to it, in case someone else comes here.
Stackdriver Logging Client Libraries for Google Cloud Platform are not in beta anymore, as they hit General Availability some time ago. The link I shared contains the most relevant documentation for installing and using them.
After running the command pip install --upgrade google-cloud-logging, you will be able to authenticate with your GCP account, and use the Client Libraries.
Using them is as easy as importing the library with a command such as from google.cloud import logging, then instantiate a new client (which you can use by default, or even pass the Project ID and Credentials explicitly) and finally work with Logs as you want.
You may also want to visit the official library documentation, where you will find all the details of how to use the library, which methods and classes are available, and how to do most of the things, with lots of self-explanatory examples, and even comparisons between the different alternatives on how to interact with Stackdriver Logging.
As a small example, let me also share a snippet of how to retrieve the five most recent logs which have status more sever than "warning":
# Import the Google Cloud Python client library
from google.cloud import logging
from google.cloud.logging import DESCENDING
# Instantiate a client
logging_client = logging.Client(project = <PROJECT_ID>)
# Set the filter to apply to the logs, this one retrieves GAE logs from the default service with a severity higher than "warning"
FILTER = 'resource.type:gae_app and resource.labels.module_id:default and severity>=WARNING'
i = 0
# List the entries in DESCENDING order and applying the FILTER
for entry in logging_client.list_entries(order_by=DESCENDING, filter_=FILTER): # API call
print('{} - Severity: {}'.format(entry.timestamp, entry.severity))
if (i >= 5):
break
i += 1
Bear in mind that this is just a simple example, and that many things can be achieved using the Logging Client Library, so you should refer to the official documentation pages that I shared in order to get a more deep understanding of how everything works.
However it doesn't seem to have any impact on the output which is
always INFO for me.
add a logging handler, e.g.:
formatter = logging.Formatter('%(asctime)s %(process)d %(levelname)s: %(message)s')
consoleHandler = logging.StreamHandler()
consoleHandler.setLevel(logging.DEBUG)
consoleHandler.setFormatter(formatter)
logger.addHandler(consoleHandler)

How do I get the Junit test results using Email-ext in Jenkins

What do I need to add to the default html_gmail.jelly script to have it show the classes that were tested including how many tests were ran within each class?
When a Jenkins job is complete you can drill down to the Junit Test Results in an address that looks like:
http://somecompany.jenkins.com/view/App_Automation/job/Application_Under_Test/129/testReport/com.AUT.testing.mobile/
The test results are generated by the build.xml so is it just a matter of pointing to that xml file?
The email-ext page shows a clean example but not the tokens that are used to achieve that: http://wiki.hudson-ci.org/download/attachments/3604514/html.jpg
Currently using the ${FAILED_TESTS} token generates a nice Tested; Failed; Skipped number, but nothing that points to which tests passed/failed/skipped. I would like to show the total number of tests including which tests were actually ran.
Thanks ahead of time
OK I figured out how to display the pass and failed methods by adding var=pass or var=fail to the token of those assignments.
First go to the Jelly script in the this path:
~/.hudson/plugins/email-ext/WEB-INF/classes/hudson/plugins/emailext/templates/automation.jelly
$DEFAULT_SUBJECT (${build.testResultAction?.failCount} ${build.testResultAction?.failureDiffString})
SETTING UP THE CONFIG IN JENKINS
DEFAULT SUBJECT:
$PROJECT_NAME - Build # $BUILD_NUMBER - $BUILD_STATUS!
DEFAULT CONTENT:
$PROJECT_NAME - Build # $BUILD_NUMBER - $BUILD_STATUS:
Check console output at $BUILD_URL to view the results.
Changes:
${CHANGES}
Changes Since Last Success
${CHANGES_SINCE_LAST_SUCCESS}
Failed Tests:
${FAILED_TESTS}
Build Log:
${BUILD_LOG}
Total Amount of Tests:
${TEST_COUNTS, var}
Total = $TEST_COUNTS
Failed = ${TEST_COUNTS,var="fail"}
Total = $TEST_COUNTS
Passed = ${TEST_COUNTS,var="pass"}
Job Description:
${JOB_DESCRIPTION}
Place this in the email job
${JELLY_SCRIPT,template="html-with-health-and-console"}
Note the templates available are noted in the path ~/.hudson/plugins/email-ext/WEB-INF/classes/hudson/plugins/emailext/templates/automation.jelly or create your own.

Determine if given job is currently running using Hudson/Jenkins API

Is there an API to determine whether a given job is currently running or not?
Ideally, I'd also like to be able to determine its estimated % complete and get the details of the SVN revision number and commit comment too!
EDIT:
I found the answer. http://host/job/project/lastBuild/api/ has almost all of what I need in it somewhere! If you kick off a manual build, it won't tell you the SCM changesets, but that makes sense. It does still tell you the latest SCM revision though, so that's good. All in all, good enough for my purposes right now.
As gareth_bowles and Sagar said, using the Jenkins API is the way to know.
If you put the depth to 1, you will see what you're looking for:
http://host/job/project/lastBuild/api/xml?depth=1
You will see there's a <building> tag to tell if that build is running
...
<build>
<action>
<cause>
<shortDescription>Started by user Zageyiff</shortDescription>
<userId>Zageyiff</userId>
<userName>Zageyiff</userName>
</cause>
</action>
<building>true</building>
<duration>0</duration>
<estimatedDuration>-1</estimatedDuration>
<fullDisplayName>Project #12</fullDisplayName>
<id>2012-08-24_08-58-45</id>
<keepLog>false</keepLog>
<number>12</number>
<timestamp>123456789</timestamp>
<url>
http://host/job/project/12
</url>
<builtOn>master</builtOn>
<changeSet/>
<mavenVersionUsed>3.0.3</mavenVersionUsed>
</build>
...
I'm using the Groovy plug-in, and run the following snippet as system:
import hudson.model.*
def version = build.buildVariableResolver.resolve("VERSION")
println "VERSION=$version"
def nextJobName = 'MY_NEXT_JOB'
def nextJob = Hudson.instance.getItem(nextJobName)
def running = nextJob.lastBuild.building
if (running) {
println "${nextJobName} is already running. Not launching"
} else {
println "${nextJobName} is not running. Launching..."
def params = [
new StringParameterValue('VERSION', version)
]
nextJob.scheduleBuild2(0, new Cause.UpstreamCause(build), new ParametersAction(params))
}
It works like a charm.
If you go to your job's page, and add "api" to the end of the URL, you'll get information on using the API.
http://yourjenkins/job/job_name/api
More information on using the Jenkins API:
https://wiki.jenkins-ci.org/display/JENKINS/Remote+access+API
If you're comfortable with digging through the Jenkins Java API, you could write a system Groovy script to get this data. The Job class is the place to start.
As stated on the /api page of your build (chapter "Accessing Progressive Console Output"), you can poll the console output with a GET request by calling <url-to-job>/lastBuild/logText/progressiveText. To quote the API doc:
If the response also contains the X-More-Data: true header, the server is indicating that the build is in progress
And there you go. You can test this behaviour by simply calling the respective URL in your browser and then inspecting the response headers with your browser's developer tools (usually accessed by pressing F12). In Firefox, the respective tab is called "network analysis" (assuming my translation is correct, my browser is not set to English). In Chrome, navigate to the "Network" tab.
This answer is based on Jenkins version 2.176.3.
It is also possible to look at the color attribute. I know it is not the wanted way. But maybe someone can make use of it.
get the overview xml via "/job/api/xml" and then check the color attribute for "anim".
