With Ubuntu 14.04 and Indigo, I cloned the pointgrey_camera_driver to catkinws/src and did catkin_make install. When I:
roslaunch pointgrey_camera_driver camera.launch
if I
rostopic echo /camera/image_color
the camera_nodelet_manager process dies. I don't know where the problem might be. This did work at one time.
I have tried using a calibration file as well as setting the launch argument "calibrated" to 0.
When the process dies this is the message:
[camera/camera_nodelet_manager-2] process has died [pid 14845, exit code -11, cmd /opt/ros/indigo/lib/nodelet/nodelet manager __name:=camera_nodelet_manager __log:=/home/mitch/.ros/log/9c7752b6-2116-11e6-a626-c03fd56e6751/camera-camera_nodelet_manager-2.log].
log file: /home/mitch/.ros/log/9c7752b6-2116-11e6-a626-c03fd56e6751/camera-camera_nodelet_manager-2*.log
The log files are not enlightening.

I'm trying to use HOL in Isabelle in batch mode from Docker, but it can't seem to find HOL.
If I have this My.thy file
theory My
imports HOL
begin
end
and then run this to process the file in batch mode
docker run --rm -it -v $PWD/My.thy:/home/isabelle/My.thy makarius/isabelle:Isabelle2022_ARM process -T My
I get
*** No such file: "/home/isabelle/HOL.thy"
*** The error(s) above occurred for theory "Draft.HOL" (line 2 of "~/My.thy")
*** (required by "Draft.My")
Exception- TOPLEVEL_ERROR raised
However, I can import Main. In more detail, if I change My.thy to be
theory My
imports Main
begin
end
then running the same Docker command as above to run the batch process results in
Loading theory "Draft.My"
### theory "Draft.My"
### 0.039s elapsed time, 0.078s cpu time, 0.000s GC time
val it = (): unit
How can I import HOL Isabelle's batch mode in Docker?
I'm trying to get a function to run in AWS Lambda that uses Selenium and Firefox/geckodriver in order to run. I've decided to go the route of creating a container image, and then uploading and running that instead of using a pre-configured runtime. I was able to create a Dockerfile that correctly installs Firefox and Python, downloads geckodriver, and installs my test code:
FROM alpine:latest
RUN apk add firefox python3 py3-pip
RUN pip install requests selenium
RUN mkdir /app
WORKDIR /app
RUN wget -qO gecko.tar.gz https://github.com/mozilla/geckodriver/releases/download/v0.28.0/geckodriver-v0.28.0-linux64.tar.gz
RUN tar xf gecko.tar.gz
RUN mv geckodriver /usr/bin
COPY *.py ./
ENTRYPOINT ["/usr/bin/python3","/app/lambda_function.py"]
The Selenium test code:
#!/usr/bin/env python3
import util
import os
import sys
import requests
def lambda_wrapper():
api_base = f'http://{os.environ["AWS_LAMBDA_RUNTIME_API"]}/2018-06-01'
response = requests.get(api_base + '/runtime/invocation/next')
request_id = response.headers['Lambda-Runtime-Aws-Request-Id']
try:
result = selenium_test()
# Send result back
requests.post(api_base + f'/runtime/invocation/{request_id}/response', json={'url': result})
except Exception as e:
# Error reporting
import traceback
requests.post(api_base + f'/runtime/invocation/{request_id}/error', json={'errorMessage': str(e), 'traceback': traceback.format_exc(), 'logs': open('/tmp/gecko.log', 'r').read()})
raise
def selenium_test():
from selenium.webdriver import Firefox
from selenium.webdriver.firefox.options import Options
options = Options()
options.add_argument('-headless')
options.add_argument('--window-size 1920,1080')
ffx = Firefox(options=options, log_path='/tmp/gecko.log')
ffx.get("https://google.com")
url = ffx.current_url
ffx.close()
print(url)
return url
def main():
# For testing purposes, currently not using the Lambda API even in AWS so that
# the same container can run on my local machine.
# Call lambda_wrapper() instead to get geckodriver logs as well (not informative).
selenium_test()
if __name__ == '__main__':
main()
I'm able to successfully build this container on my local machine with docker build -t lambda-test . and then run it with docker run -m 512M lambda-test.
However, the exact same container crashes with an error when I try and upload it to Lambda to run. I set the memory limit to 1024M and the timeout to 30 seconds. The traceback says that Firefox was unexpectedly killed by a signal:

I had it upload the geckodriver logs as well, but there wasn't much useful information in there:

*** You are running in headless mode.
How can I even begin to debug this? The fact that the exact same container behaves differently depending upon where it's run seems fishy to me, but I'm not knowledgeable enough about Selenium, Docker, or Lambda to pinpoint exactly where the problem is.
Is my docker run command not accurately recreating the environment in Lambda? If so, then what command would I run to better simulate the Lambda environment? I'm not really sure where else to go from here, seeing as I can't actually reproduce the error locally to test with.
If anyone wants to take a look at the full code and try building it themselves, the repository is here - the lambda code is in lambda_function.py.
As for prior research, this question a) is about ChromeDriver and b) has no answers from over a year ago. The link from that one only has information about how to run a container in Lambda, which I'm already doing. This answer is almost my problem, but I know that there's not a version mismatch because the container works on my laptop just fine.
I have exactly the same problem and a possible explanation.
I think what you want is not possible for the time being.
According to AWS DevOps Blog Firefox relies on fallocate system call and /dev/shm.
However AWS Lambda does not mount /dev/shm so Firefox will crash when trying to allocate memory. Unfortunately, this handling cannot be disabled for Firefox.
However if you can live with Chromium, there is an option for chromedriver --disable-dev-shm-usage that disables the usage of /dev/shm and instead writes shared memory files to /tmp.
chromedriver works fine for me on AWS Lambda, if that is an option for you.
According to AWS DevOps Blog you can also use AWS Fargate to run Firefox/geckodriver.
There is an entry in the AWS forum from 2015 that requests mounting /dev/shm in Lambdas, but nothing happened since then.
I am trying to set Jenkins up to perform continuous testing of some online applications.
I have installed Jenkins on Ubuntu 16.04 and have a slave which is running Windoze 10.
I have installed UltraVnc on the slave and am trying to get VncRecorder to record the test session.
At the moment, my job simply does some random stuff. The console output is as follows:

Problem Steps Recorder is a cool Windows tool that can record your actions as a series of images. You can use this tool which is built-into windows :)
psr.exe [/start |/stop][/output <fullfilepath>] [/sc (0|1)] [/maxsc <value>]
[/sketch (0|1)] [/slides (0|1)] [/gui (o|1)]
[/arcetl (0|1)] [/arcxml (0|1)] [/arcmht (0|1)]
[/stopevent <eventname>] [/maxlogsize <value>] [/recordpid <pid>]
/start :Start Recording. (Outputpath flag SHOULD be specified)
/stop :Stop Recording.
/sc :Capture screenshots for recorded steps.
/maxsc :Maximum number of recent screen captures.
/maxlogsize :Maximum log file size (in MB) before wrapping occurs.
/gui :Display control GUI.
/arcetl :Include raw ETW file in archive output.
/arcxml :Include MHT file in archive output.
/recordpid :Record all actions associated with given PID.
/sketch :Sketch UI if no screenshot was saved.
/slides :Create slide show HTML pages.
/output :Store output of record session in given path.
/stopevent :Event to signal after output files are generated.
PSR Usage Examples:
psr.exe
psr.exe /start /output fullfilepath.zip /sc1 /gui 0 /record <PID>
/stopevent <eventname> /arcetl 1
psr.exe /start /output fullfilepath.xml /gui 0 /recordpid <PID>
/stopevent <eventname>
psr.exe /start /output fullfilepath.xml /gui 0 /sc 1 /maxsc <number>
/maxlogsize <value> /stopevent <eventname>
psr.exe /stop
Notes:
1. Output path should include a directory path (e.g. '.\file.xml').
2. Output file can either be a ZIP file or XML file
3. Can't specify /arcxml /arcetl /arcmht /sc etc. if output is not a ZIP file.
The port number of your VNC server 0 looks suspicious..
What about the firewall settings of your slave - is the vnc port blocked ?
You could verify port of your vncserver with vncviewer 172.24.27.210:.

When I run opensipsctl start command for start opensips that time I got one error.
ERROR: PID file /var/run/opensips.pid does not exist -- OpenSIPS start failed
So please help me to solve it.
open up opensipsctl, it includes the file opensipsctlrc, which defined $PID_FILE as /var/run/opensips.pid
Then in opensipsctl, when you run start one of the checks is..
if [ ! -s $PID_FILE ] ; then
echo
merr "PID file $PID_FILE does not exist -- OpenSIPS start failed"
exit 1
fi
Which is saying if then check of whethever '/var/run/opensips.pid exists and is bigger than 0 bytes' fails, then echo out the above error.
This means the file isn't being created.
If you look just above that line it does..
if [ $SYSLOG = 1 ] ; then
$OSIPSBIN -P $PID_FILE $STARTOPTIONS 1>/dev/null 2>/dev/null
else
$OSIPSBIN -P $PID_FILE -E $STARTOPTIONS
fi
Which is where opensips actually starts. I would suggest adding the following to your opensips.cfg if you havn't already..
# Logging
debug=6
log_stderror=no
log_facility=LOG_LOCAL0
..now everything will be logged to /var/log/syslog on boot.
Try boot again, then look at that log for info about what's happened.
Another thing to check, is the user you're running opensips as has permission to access the directory it's trying to create the pid file in.
I had the same error & it was driving me mad as well. I managed to trace it down to one of two things - I had both!
1/ A misconfiguration in the OpenSIPS config file. journalctl -xe should be able to tell you what the error is
2/ Something else is listening on the port that you are trying to listen on
For 2, you can try the below, if you have Ubuntu, to see if anything is already listening on that port
lsof -i :5060
I was able to see logs and fix issue by below steps
Set log_level=4 in opensips.cfg to view debug logs in /var/log/syslog
debug is deprecated in 2.4 and higher version.
You can refer here for different log level
I have downloaded and compiled some Ros nodes from here (just to have more info). I am trying to launch the five ROS nodes with parameters using a launchfile that is taken from that repo.
After executing source catkin_ws/devel_isolated/setup.bash and executing roslaunch crab.launch(the launch file from the link above) the next error appears:

I have reinstalled the packages as suggested in some other threats about similar problems.
I also have noticed that
1º- if I move all the executablesof the nodes to the folder src/<package>/, I'm able to execute roslaunch crab.launch. But I don´t want to leave it like that, not proper way to work ;)
Additional info:
2º- If I execute, for example, source devel_isolated/<package>/setup.bashand then roslaunch crab.launch, the package which I have just source-d works and executes... (while the other still don't)
3º- So I have source-d all the source devel_isolated/<package>/setup.bash and try again: no one worked this time.
This leads to think that the problems are due to ROS variable enviroment: if I make an export | grep ROSafter 2º, I can see that the package path appears in $ROS_PATH-s and the others are not there:
root#beaglebone:~# export | grep ROS

Seems that 3º overwrites the source executed before..., meaning that in ROS_PACKAGE_PATHdoes not appear all he packages as they should.
I also have tried to force ROS_PACKAGE_PATHusing exportcommand, but it didn't work. So, I have to change more environment variables apart from that, but don't know which one...
So, I don't know if I diagnosis is correct and, if so, what should I do to correct this... Hope I have gathered enough info.
Thanks in advance!!

set the executable bit for files. most probably you need to set executable permissions for files.
chmod +x filename.
