I have created a custom filter for Kurento Media Server using gstreamer.
as per the documentation I have created the .deb file debuild -us -uc and installed it because of which the libkmscustomfiltermodule.so is generated at /usr/lib/x86_64-linux-gnu/kurento/modules/
Initially it was listed in the loaded modules but I deleted this .so and after this its not listed (sudo kurento-media-server --list)
even if I revert my changes and restart the kurent-media-server-6.0 service, this customfilter is not being listed in sudo kurento-media-server --list
in server logs I see this log:
ModuleManager.cpp:61 loadModule() Module /usr/lib/x86_64-linux-gnu/kurento/modules/libkmscustomfiltermodule.so cannot be loaded:
/usr/lib/x86_64-linux-gnu/libkmscustomfilterimpl.so.0: undefined symbol: _ZN7kurento6module15customfilter19CustomFilterImpl4loopE
any idea why this is happening ?
It seems that your module has some symbols missing.
To detect this errors, it's a good practice to create a test that tries to load the module and instantiate classes in there. This way you know if your module is build correctly before trying it in the mediaserver.
This test is done in kms-elements, you can use it as an example:

In short: why index.android.bundle is not uploaded to Sentry server following expo's guide
I made a GitHub issue as I tested this with a clean repository. And there I specified the issue better and with more detail. The main problem could be the script I'm using. I will link the issue here:
https://github.com/expo/sentry-expo/issues/313
Hello.
I'm using the latest sentry-expo which correctly sends errors to sentry server.
I have followed the documentation from https://docs.expo.dev/guides/using-sentry/#uploading-source-maps-for-updates
On new builds index.android.bundle and .map is uploaded to sentry.
But when I make an update running eas update and following the sentry-cli releases... script as documented in expo guide, the android-'hash'.map file is uploaded and index.android.bundle is not.
Therefore dist is different between .js and .map file and Sentry issues don't contain source map information:
Source code was not found (see Troubleshooting for JavaScript)
Url app:///index.android.bundle
But if I change index.android.bundle to index.android.bundle.js in Sentry-cli --rewrite command the bundle is uploaded but issues still show the same information probably due to that android Archive is ~/index.android.bundle.js but the issue is expecting ~/index.android.bundle.
package versions:
"#sentry/react-native": "4.9.0",
"expo": "~47.0.8",
"sentry-expo": "~6.0.0",
I add here that I'm on Windows and couldn't get sentry-cli release to work as it is documented in expo-sentry tutorial. I used this script
cross-env ./node_modules/#sentry/cli/bin/sentry-cli releases --org 'organization name' --project 'project name' files 'release name' upload-sourcemaps --dist 'Android Update ID' --rewrite dist/bundles/index.android.bundle dist/bundles/android-'hash'.map
Thank you for all the help!
Android*.js file simply needed to be changed to index.android.bundle not to index.android.bundle.js. Now source maps are showing correctly.
Expo documentation showed everything correctly but my own understanding added the need of .js in file naming. Bundle file without any extension works correctly
When working with a ColdFusion server you can access the CFIDE/administrator to set config values, which update the cfusion/lib/ xml files (e.g. neo-runtime.xml, neo-mail.xml, etc.)
I'd like to automate a deployment process that includes setting these administrator values so that I don't have to log in and manually set them for each new box that shares settings. I'm unsure of the best way to go about it.
Some thoughts I had are:
Replacing the full files with ones containing my custom settings. I've done this for local development, but it may not be an ideal method due to CF hot-fixes potentially adding/removing/changing attributes.
A script to read the wddx xml file and replace the attribute values. I'm having trouble finding information about how to do this method.
Has anyone done anything like this before? Or does anyone have any recommendations on how to best go about this?
At one company, we checked all the neo-*.xml files into source control, with a set for each environment Devs only had access to the dev settings and we could deploy a local development environment with all the correct settings for new employees quickly.
but it may not be an ideal method due to CF hot-fixes potentially adding/removing/changing attributes.
You have to keep up with those changes and migrate each environment appropriately.
While I was there, we upgraded from 8 to 9, 9 to 11 and from 11 to 2016. Environments would have to be mixed as it took time to verify the applications worked with each new version of CF. Each server got their correct XML files for that environment and scripts would copy updates as needed. We had something like 55 servers in production running 8 instances each, so this scaled well.
There is a very usefull tool developed by Ortus Solutions for this kind of automatizations called cfconfig that can be installed with their commandbox command line utility. This tool isn't only capable of setting configurations of the administrator: It is also capable of exporting/importing settings to a json file (cfconfig.json). It might be what you need.
Here is the link to their docs
https://cfconfig.ortusbooks.com/introduction/getting-started-guide
CFConfig worked perfectly for my needs. I marked #AndreasRu answer as accepted for introducing me to that tool! I'm just adding this response with some additional detail for posterity.
Install CommandBox as part of deployment script
Install CFConfig as part of deployment script
Use CFConfig to export a config.json file from an existing box that will share settings with the new deployment. Store this json file in source control for each type/env of box.
Use CFConfig to import the config.json as part of deployment script
Here's a simple example of what this looks like on debian
# Installs CommandBox
curl -fsSl https://downloads.ortussolutions.com/debs/gpg | apt-key add -
echo "deb https://downloads.ortussolutions.com/debs/noarch /" | tee -a /etc/apt/sources.list.d/commandbox.list
apt-get update && apt-get install apt-transport-https commandbox
# Installs CFConfig module
box install commandbox-cfconfig
# Import config settings
box cfconfig import from=/<path-to-config>/config.json to=/opt/ColdFusion/cfusion/ toFormat=adobe#11.0.19
Please help I have trouble with Divio App trying to making it work.
When I press "set up project"
it gives me this

There was an error trying to run a command. This is most likely
not an issue with divio-cli, but the called program itself.
Try checking the output of the command above.
The command was:

I also tried this from virtual MacOS and getting this message:
https://i.stack.imgur.com/QccvY.png
I also tried to mess arouond with creating SSH keys but didn't work out.
Can someone provide me step by step explanation how to make this wonderful app work?
In the Windows examples you show, I see:
Bad owner or permissions on /home/divio/.ssh/config
I am not sure how that has happened, but that is what is preventing your local environment from providing the expected key to the Divio Control Panel.
In the Macintosh example, the environment doesn't have a key that the Control Panel knows about.
You will need to add the key (probably from ~/.ssh/rsa_id.pub) to https://control.divio.com/account/ssh-keys/. If you don't already have a key in the Macintosh environment, you will need to set one up.
For anyone who may face this issue. On my MacOS virtual machine I managed to find solution. Looks like it is Internet Service Provider blocking port 22 something like that. Okay looks like problem resolved. I used VPN and without any hastle with SSH I got different result. Looks like it is working now not finished creating project yet but promising:

I'm working on an app with Firebase and Facebook SDKs, but I have a problem installing Facebook SDK for some reason. Firebase works just fine and I've followed the official facebook guide for Swift. Here's my Podfile:
platform :ios, '10.0'
target 'MyApp_iOS' do
use_frameworks!
# Pods for MyApp_iOS
pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'Firebase/Database'
pod 'Firebase/Messaging'
pod 'Firebase/Storage'
pod 'FacebookCore'
pod 'FacebookLogin'
I'm getting the 'no such module "FacebookLogin"' error when I try importing FacebookLogin. I've tried installing FBSDKCoreKit and changing platform 9.0 to 10.0 but I got same result. What am I doing wrong?
Here is what you need to do:
Create a directory for your project
Create a new Xcode project in the directory from step 1
In the directory you created run pod init
This will create a Podfile
In the Podfile add the pods you need
Run pod install this will download the needed pod files and create an .xcworkspace file with a name like MyApp_iOS.xcworkspace.
Close the existing xccodeproj file and open the xcworkspace file
Make all you changes in the xcworkspace file. Now FacebookLogin is available.
Special thanks to Thiago for his help with this issue.
I'm just having a bit of trouble understanding why this command:
>appcfg.py -A adept-box-109804 update app.yaml
as given by the Try Google App Engine Now page does not work. I have downloaded the App Engine SDK for Python, and have Path set up to point to the location of appcfg.py, but running appcfg.py in my projects root directory does not work in the command line. I either have to navigate to the folder containing appcfg.py and do
>python appcfg.py help
or do
>python "C:\Program Files (x86)\Google\google_appengine\appcfg.py" help
to get a command to work from anywhere. I used the latter method to deploy my test app, but was just wondering if someone could explain why the command as given by the simple Google tutorial did not do anything. I also checked to make sure that .py files are automatically opened with the Python 2.7 interpreter, such that a file hello.py will be executed in the command line by simply typing
>hello.py
and it will output its print statement. On the other hand, using appcfg.py in a similar manner gives the same output no matter the arguments (please note I truncated the output, but rest assured that they are identical no matter the arguments:

I finally tracked down the real reason, and it wasn't a bug with the AppEngine SDK. Rather it was with my Python interpreter, as I noticed it wasn't accepting arguments for any .py files. It turned out to be a registry error, located at [HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command] where I had to change the value from "C:\Python27\python.exe" "%1" to "C:\Python27\python.exe" "%1" %*
How this happened, whether it be the Python 2.7 installer, or maybe the AppEngine SDK, I'm not sure though.
Your confusion probably stems from mixing up 2 possible invocations styles:
python appcfg.py ...
appcfg.py ...
The 1st one can't make use of the fact that the location of the appcfg.py is in the path, it is just an argument to the python executable, which can not locate the appcfg.py file unless either:
it finds it in the current directory
the appcfg.py file is specified using a full path or a path relative to the current working directory from which python is invoked
This is the reason for which your 2nd and 3rd commands don't work as you'd expect. Using the 2nd invocation style instead should work if the location of the appcfg.py is in the path - just as your last command invocation does.
Key point to remember: the path configuration applies to the command executable only, not to its arguments (which BTW each executable may process as it wishes, some executables may combine arguments with the path configuration to obtain location of files).
Similarly appcfg.py itself (once successfully invoked using either of the 2 invocation styles) needs to be able to locate your app.yaml file specified as argument. It cannot do so unless either:
it finds it in the current directory
the app.yaml file (or its directory) is specified using a full path or a path relative to the current working directory from which appcfg.py is invoked
I suspect appcfg.py's inability to locate your app.yaml file may be the reason for which the 1st command you mentioned didn't work. If not you should provide details about the failure.
Regarding why the output of your last command is identical regardless of the arguments, I'm not sure, it could be a bug in the windows version of the SDK. In linux the output is different:
> appcfg.py help backends
Usage: appcfg.py [options] backends <directory> <action>
Perform a backend action.
The 'backends' command will perform a backends action.

from app.yaml file.
-r RUNTIME, --runtime=RUNTIME
Override runtime from app.yaml file.
-E NAME:VALUE, --env_variable=NAME:VALUE
Set an environment variable, potentially overriding an
env_variable value from app.yaml file (flag may be
repeated to set multiple variables).
-R, --allow_any_runtime
Do not validate the runtime in app.yaml

Google Compute Engine VM in which appcfg is being
called
--noauth_local_webserver
Do not run a local web server to handle redirects
during OAuth authorization.
I had this problem, and is deepened in local variable python version that different from app engine python version.
So the solution is just to add before the script the current python version location:
C:\Python27\python.exe "C:\Program Files (x86)\Google\google_appengine\appcfg.py"
And it just return to work well.
