I am attempting to install the certbot package for nix, and it fails during the tests every time because the tests hit the open file limit on the system. I have modified the certbot install script just enough to print out the ulimit at the beginning of the patchPhase and find that the maximum number of allowed open files is 256. However, in the shell from which I am executing nix-shell or nix-env, my ulimit (both hard and soft) is set to 100000.
How can I propogate that limit down to the certbot build process? I would like to avoid trying to figure out how to modify the python build script that certbot uses.
Running a Bash shell on OSX 10.13.
Manually raise the ulimit in the patchPhase stanza of certbot.nix. Turns out that this change propogates through the rest of the phases in the certbot build script.
buildInputs = [ dialog ] ++ (with python2Packages; [ nose mock gnureadline ]);
patchPhase = ''
ulimit -n 8196
substituteInPlace certbot/notify.py --replace "/usr/sbin/sendmail" "/run/wrappers/bin/sendmail"
substituteInPlace certbot/util.py --replace "sw_vers" "/usr/bin/sw_vers"
'';
postInstall = ''
I will submit a patch to nixpkgs.

i am new in react native i want to run react native app in IOS after react-native init, app not run in IOS show some error
Showing All Messages
bash: Native/social_login/socialLogin/node_modules/react-native/scripts/../Libraries: No such file or directory
Command PhaseScriptExecution failed with a nonzero exit code
and build failed please help me
versions
"react": "17.0.1",
"react-native": "0.64.0"
command line tools : Xcode 12.4 (12D4e)
This happened also to me upgrading from 0.63 to 0.64. After trying all solutions I followed a solution moving the folder to a directory where the path contain no spaces and it works and build the app successfully.
Solution to React Native 0.64 build fail
In order for this to work properly follow these steps:
If you previously installed a global react-native-cli package, please
remove it as it may cause unexpected issues (i.e. npm uninstall -g
react-native-cli)
Move the project folder in a path with no spaces (i.e. ~/sub folder
name/ReactNativeApp won't work till you have spaces in the path, so
move in a path like ~/folder/ReactNativeApp)
Then cd into the project folder and upgrade react native to the
latest version with npx react-native upgrade and resolve conflicts if
any
After upgrading remove the node_modules folder and the yarn.lock from
the root and the podfile.lock and Pods folder from ios subfolder
Then cd back to the root and run yarn install && npx pod-install
Now run again your app in Xcode or your IDE and it works
Crazy and absurd that a space in the path-name could cause this issue
This is nothing just an issue with the scheme name for me, in my case my scheme name contains whitespace e.g. "ABC staging", which is not allowed, it got fixed after deleting and creating a new scheme with the name "ABC-staging".
in the case of react-native 0.67^, you may need to apply these changes as well
change line no 7
set -e. ==> set +e
in
node_modules/react-native/scripts/find-node.sh
then use patch-package using the following command :
npx patch-package react-native
this will create a patch file inside the patch folder in root, then you can add in the post-install script in package.json:
"postinstall": "npx patch-package"
This command will run each time a new package is getting added to the project and auto-fix react-native find-node. sh.
Try to run pod install in ios folder
cd ios && pod install
Then when it's done go back to your main folder and run
yarn run ios
If that doesn't work, check out the solutions here

There seems to be an issue with coreutils on macOS.
What fixed it for me is:
brew install coreutils
brew install findutils
brew install gnu-sed

if your get invalid identifier error in react-native-xcode.sh then under Build Phases -> Bundle React Native code and images it should be: (notice the double quotes):
set -e
export NODE_BINARY="node ../node_modules/react-native/scripts/react-native-xcode.sh"
use patch-package react-native to patch it (if project is being developed on different machines then they must install the brew packages above)
For me it was just having a space in folder name which was in the path of project folder from root.
I had to delete the contents of my ~/.bash_profile file.
I don't even use bash, but some other script populated the file and that broke my build. Deleting the contents fixed the build, immediately. Might not work for you, but thought I'd share.
I'm running Xcode 13.4.1
Installed cocoapods using brew install cocoapods (https://brew.sh/index_es)
M2 apple chip
React Native 0.70
Actually after spending a whole lot of time trying different solutions none of them worked except for Giuseppe's answer. I had white spaces in my path
"/React Native/exampleProject"
1. Renamed folders/files to remove any white space in the path (creating a fresh project within the fixed path worked with no problems at all)
I didn't even had to execute pod install anymore in the ios folder
In my case, i had to export the right path to node
in your terminal type which node, copy the path and export it in ios/xcode.env
export NODE_BINARY="copied node path"
Ok, worth trying this.
(This usually happens if you had multiple imports or any imports missing)
As soon as we get this error message:
Always scroll up & read the issue if written in that log file. Any issues like syntax error or issue related to your js code.
If yes, you can fix that first & re build it.
In my case I had multiple imports of one of the RN components.
Adding $(ARCHS_STANDARD) to Valid Architectures in Build Settings solved it for me
I am new to Fabric 2.0 and recently installed all samples and I was able to run test-network without an issue with 2 orgs. Then I followed the directory on addOrg3 to add 3rd organization and join the channel I created earlier.
Now the fun part came in when I wanted to add 4th organization. What I did was, I copied the addOrg3 folder and renamed almost everything in each file to represent 4th organization. I even assigned new PORT for this organization. However I am seeing the following error.
I've also added the following in Scripts/envVar.sh
export PEER0_ORG4_CA=${PWD}/organizations/peerOrganizations/org4.example.com/peers/peer0.org4.example.com/tls/ca.crt
And added the following in envVarCLI.sh
elif [ $ORG -eq 4 ]; then
CORE_PEER_LOCALMSPID="Org4MSP"
CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG4_CA
CORE_PEER_ADDRESS=peer0.org4.example.com:12051
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/organizations/peerOrganizations/org4.example.com/users/Admin#.../msp
I have also added step1Org4.sh and step2Org4.sh basically following by following addOrg3's structure.
What steps do you follow to add additional organizations ? Please help.

Sorry for the formatting since I wasn't able to put in to coding style but here is the output from running the command "./addOrg4.sh up"

In your addOrg4.sh have condition check like this:
CONTAINER_IDS=$(docker ps -a | awk '($2 ~ /fabric-tools/) {print $1}')
if [ -z "$CONTAINER_IDS" -o "$CONTAINER_IDS" == " " ]; then
echo "Bringing up network"
Org4Up
fi
If you already run addOrg3.sh up, CONTAINER_IDS alway have value (Example: 51b4ad60d812). It is ContainerID of Org3cli. So function Org4Up will never call. Simple way is just comment code like this:
# CONTAINER_IDS=$(docker ps -a | awk '($2 ~ /fabric-tools/) {print $1}')
# if [ -z "$CONTAINER_IDS" -o "$CONTAINER_IDS" == " " ]; then
echo "Bringing up network"
Org4Up
# fi
It will bring up Org4cli you missing.
First check the container is up or not and if it is up then I think the CLI where the command is executed is not bootstrapped with the Org4 details.
I have added the 4th Organization from the three Org Hyperledger Fabric Network .Firstly, you have to create the Org4-artifacts (Crypto.yaml and Org4 docker file including the Org4Cli) and then try to follow the manual (step by step) process to add the new Organization from the official documentation.
https://hyperledger-fabric.readthedocs.io/en/release-2.0/channel_update_tutorial.html
Omit the process of editing scripts (step1 Org3.sh ...) because the workflow for adding the 4th or a new Org is slightly changed.So,you will spend a lot of time in just modifying the scripts.
I will write an article to add a new Org (4th) on medium,will paste the link here too.
Can you help me, why I get sometimes (50:50):
webkit_server.NoX11Error: Cannot connect to X. You can try running with xvfb-run.
When I start the script in parallel as:
xvfb-run -a python script.py
You can reproduce this yourself like so:
for ((i=0; i<10; i++)); do
xvfb-run -a xterm &
done
Of the 10 instances of xterm this starts, 9 of them will typically fail, exiting with the message Xvfb failed to start.
Looking at xvfb-run 1.0, it operates as follows:
# Find a free server number by looking at .X*-lock files in /tmp.
find_free_servernum() {
# Sadly, the "local" keyword is not POSIX. Leave the next line commented in
# the hope Debian Policy eventually changes to allow it in /bin/sh scripts
# anyway.
#local i
i=$SERVERNUM
while [ -f /tmp/.X$i-lock ]; do
i=$(($i + 1))
done
echo $i
}
This is very bad practice: If two copies of find_free_servernum run at the same time, neither will be aware of the other, so they both can decide that the same number is available, even though only one of them will be able to use it.
So, to fix this, let's write our own code to find a free display number, instead of assuming that xvfb-run -a will work reliably:
#!/bin/bash
# allow settings to be updated via environment
: "${xvfb_lockdir:=$HOME/.xvfb-locks}"
: "${xvfb_display_min:=99}"
: "${xvfb_display_max:=599}"
# assuming only one user will use this, let's put the locks in our own home directory
# avoids vulnerability to symlink attacks.
mkdir -p -- "$xvfb_lockdir" || exit
i=$xvfb_display_min # minimum display number
while (( i < xvfb_display_max )); do
if [ -f "/tmp/.X$i-lock" ]; then # still avoid an obvious open display
(( ++i )); continue
fi
exec 5>"$xvfb_lockdir/$i" || continue # open a lockfile
if flock -x -n 5; then # try to lock it
exec xvfb-run --server-num="$i" "$#" || exit # if locked, run xvfb-run
fi
(( i++ ))
done
If you save this script as xvfb-run-safe, you can then invoke:
xvfb-run-safe python script.py
...and not worry about race conditions so long as no other users on your system are also running xvfb.
This can be tested like so:
for ((i=0; i<10; i++)); do xvfb-wrap-safe xchat & done
...in which case all 10 instances correctly start up and run in the background, as opposed to:
for ((i=0; i<10; i++)); do xvfb-run -a xchat & done
...where, depending on your system's timing, nine out of ten will (typically) fail.
This questions was asked in 2015.
In my version of xvfb (2:1.20.13-1ubuntu1~20.04.2), this problem has been fixed.
It looks at /tmp/.X*-lock to find an available port, and then runs Xvfb. If Xvfb fails to start, it finds a new port and retries, up to 10 times.
I'm entirely new to using bash and Xcode build scripts and so my code is probably a jungle full of errors.
The idea here is to trigger the script below which will scrape the directory that it is saved in for any .js automation scripts. It will then send these scripts to instruments to be run one at a time. I found some nifty code that created time stamped files and so I used that to create a more meaningful storage system.
#!/bin/bash
# This script should run all (currently only one) tests, independently from
# where it is called from (terminal, or Xcode Run Script).
# REQUIREMENTS: This script has to be located in the same folder as all the
# UIAutomation tests. Additionally, a *.tracetemplate file has to be present
# in the same folder. This can be created with Instruments (Save as template...)
# The following variables have to be configured:
#EXECUTABLE="Plans.app"
# Find the test folder (this script has to be located in the same folder).
ROOT="$( cd -P "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
# Prepare all the required args for instruments.
TEMPLATE=`find $ROOT -name '*.tracetemplate'`
#EXECUTABLE=`find ~/Library/Application\ Support/iPhone\ Simulator | grep "${EXECUTABLE}$"`
echo "$BUILT_PRODUCTS_DIR"
echo "$PRODUCT_NAME"
EXECUTABLE="${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.app/"
SCRIPTS=`find $ROOT -name '*.js'`
# Prepare traces folder
TRACES="${ROOT}/Traces/`date +%Y-%m-%d_%H-%M-%S`"
mkdir -p "$TRACES"
printf "\n" >> "$ROOT/results.log"
echo `date +%Y-%m-%d_%H-%M-%S` >> "$ROOT/results.log"
# Get the name of the user we should use to run Instruments.
# Currently this is done, by getting the owner of the folder containing this script.
USERNAME=`ls -l "${ROOT}/.." | grep \`basename "$ROOT"\` | awk '{print $3}'`
# Bring simulator window to front. Depending on the localization, the name is different.
osascript -e 'try
tell application "iPhone Simulator" to activate
on error
tell application "iOS Simulator" to activate
end try'
# Prepare an Apple Script that promts for the password.
PASS_SCRIPT="tell application \"System Events\"
activate
display dialog \"Password for user $USER:\" default answer \"\" with hidden answer
text returned of the result
end tell"
# Run all the tests.
for SCRIPT in $SCRIPTS; do
echo -e "\nRunning test script $SCRIPT"
TESTC="sudo -u ${USER} xcrun instruments -l -c -t ${TEMPLATE} ${EXECUTABLE} -e UIARESULTSPATH ${TRACES}/${TRACENAME} -e UIASCRIPT ${SCRIPT} >> ${ROOT}/results.log"
#echo "$COMMAND"
echo "Executing command $TESTC" >> "$ROOT/results.log"
echo "here $TESTC" >> "$ROOT/results.log"
OUTPUT=$(TESTC)
echo $OUTPUT >> "$ROOT/results.log"
echo "Finished logging" >> "$ROOT/results.log"
SCRIPTNAME=`basename "$SCRIPT"`
TRACENAME=`echo "$SCRIPTNAME" | sed 's_\.js$_.trace_g'`
for i in $(ls -A1t $PWD | grep -m 1 '.trace')
do
TRACEFILE="$PWD/$i"
done
if [ -e $TRACEFILE ]; then
mv "$TRACEFILE" "${TRACES}/${TRACENAME}"
fi
if [ `grep " Fail: " results.log | wc -l` -gt 0 ]; then
echo "Test ${SCRIPTNAME} failed. See trace for details."
open "${TRACES}/${TRACENAME}"
exit 1
break
fi
done
rm results.log
A good portion of this was taken from another Stack Overflow answer but because of the repository setup that I'm working with I needed to keep the paths abstract and separate from the root folder of the script. Everything seems to work (although probably not incredibly efficiently) except for the actual xcrun command to launch instruments.
TESTC="sudo -u ${USER} xcrun instruments -l -c -t ${TEMPLATE} ${EXECUTABLE} -e UIARESULTSPATH ${TRACES}/${TRACENAME} -e UIASCRIPT ${SCRIPT} >> ${ROOT}/results.log"
echo "Executing command $TESTC" >> "$ROOT/results.log"
OUTPUT=$(TESTC)
This is turned into the following by whatever black magic Bash runs on:
sudo -u Braains xcrun instruments -l -c -t
/Users/Braains/Documents/Automation/AppName/TestCases/UIAutomationTemplate.tracetemplate
/Users/Braains/Library/Developer/Xcode/DerivedData/AppName-
ekqevowxyipndychtscxwgqkaxdk/Build/Products/Debug-iphoneos/AppName.app/ -e UIARESULTSPATH

UIASCRIPT /Users/Braains/Documents/Automation/AppName/TestCases/Test-Case_1js
(^ Has inserted line breaks for clarity of the question ^)
The resulting error that I am seeing is:
posix spawn failure; aborting launch (binary ==
/Users/Braains/Library/Developer/Xcode/DerivedData/AppName-
ekqevowxyipndychtscxwgqkaxdk/Build/Products/Debug-iphoneos/AppName.app/AppName).
I have looked all over for a solution to this but I can't find anything because Appium has a similar issue. Unfortunately I don't understand the systems well enough to know how to translate the fixes to Appium to my own code but I imagine it's a similar issue.
I do know that the posix spawn failure is related to threading, but I don't know enough about xcrun to say what's causing the threading issue.
Related info:
- I'm building for the simulator but it'd be great to work on real devices too
- I'm using xCode 5.1.1 and iOS Simulator 7.1
- This script is meant to be run as a build post action script in xCode
- I did get it briefly working once before I broke it and couldn't get it back to the working state. So I think that means all of my permissions are set correctly.
UPDATE: So I've gotten to the root of this problem although I have not found a fix yet. First of all I have no idea what xcrun is for and so I dropped it. Then after playing around I found that my Xcode environment variables are returning the wrong path, probably because of some project setting somewhere. If you copy the Bash command from above but replace Debug-iphoneos with Debug-iphonesimulator the script can be run from the command line and will work as expected.
So for anyone who happens across this the only solution I could find was to hardcode the script for the simulator.
I changed EXECUTABLE="${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.app/" to be EXECUTABLE="${SYMROOT}/Debug-iphonesimulator/${EXECUTABLE_PATH}". This is obviously not a great solution but it works for now.
I am looking for functionality where we have a directory with some files in it.
Whenever any one makes a change in any of the files in the directory, jenkins shoukd trigger a build.
Is there any plugin or mathod for this functionality. Please advise.
Thanks in advance.
I have not tried it myself, but The FSTrigger plugin seems to do what you want:
FSTrigger provides polling mechanisms to monitor a file system and
trigger a build if a file or a set of files have changed.
If you can monitor the directory with a script, you can trigger the build with a HTTP GET, for example with wget or curl:
wget -O- $JENKINS_URL/job/JOBNAME/build
Although slightly related.. it seems like this issue was about monitoring static files on system.. however there are many version control systems for just this purpose.
I answered this in another post if you're using git to track changes on the files themselves:
#!/bin/bash
set -e
job_name="whatever"
JOB_URL="http://myserver:8080/job/${job_name}/"
FILTER_PATH="path/to/folder/to/monitor"
python_func="import json, sys
obj = json.loads(sys.stdin.read())
ch_list = obj['changeSet']['items']
_list = [ j['affectedPaths'] for j in ch_list ]
for outer in _list:
for inner in outer:
print inner
"
_affected_files=`curl --silent ${JOB_URL}${BUILD_NUMBER}'/api/json' | python -c "$python_func"`
if [ -z "`echo \"$_affected_files\" | grep \"${FILTER_PATH}\"`" ]; then
echo "[INFO] no changes detected in ${FILTER_PATH}"
exit 0
else
echo "[INFO] changed files detected: "
for a_file in `echo "$_affected_files" | grep "${FILTER_PATH}"`; do
echo " $a_file"
done;
fi;
You can add the check directly to the top of the job's exec shell, and it will exit 0 if no changes detected.. Hence, you can always poll the top level of the repo for check-in's to trigger a build. And only complete a build if the files in question change.
