Can I pass along all properties when for a GradleBuild task? - build

I'm executing a GradleBuild task, and I'd like to maintain all the properties that the current script has been given. In other words, I want to package up "these startparameters" and pass them along to the build I'm calling.
Is there any way to do this cleanly?

If you mean project properties:
task foo(type: GradleBuild) {
startParameter.projectProperties = gradle.startParameter.projectProperties
}
If you mean system properties, replace projectProperties with systemPropertiesArgs (on both sides).

Can log4j and java util logging coexist

My application uses log4j but OkHttpClient uses java util logging. So apart from log4j.properties, I created a logging.properties file with the following contents:
handlers=java.util.logging.FileHandler
.level=FINE
okhttp3.internal.http2.level=FINE
java.util.logging.FileHandler.pattern = logs/%hjava%u.log
java.util.logging.FileHandler.limit = 50000
java.util.logging.FileHandler.count = 1
java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter
java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
I then added this to jvm params used for starting the application -Djava.util.logging.config.file="file://${BASE_DIR}/logging.properties"
But I don't see any new folders being created as indicated by the Filehandler. Any one know why?
But I don't see any new folders being created as indicated by the Filehandler. Any one know why?
The FileHandler will not create any new folders. A directory must be created before the FileHandler will create a file.
The system property requires a path to file that is located on the filesystem It will not expand system properties or environment variables by using the dollar sign syntax.
You can use a relative path based off of the working directory or you have to use an absolute path to the logging.properties. The logging properties can not be packaged inside of an archive.
If you want to work around this limitation then you want to create a custom config class and use the java.util.logging.config.class property in conjunction with the java.util.logging.config.file property. You then write a class that reads the file://${BASE_DIR}/logging.properties and performs the needed transformation into a path to a file. Then update the configuration if you are using JDK9 or newer. On older versions you need to use readConfiguration and add code to work work around limitations of the LogManager

Implementing your own property system (Qt-like)

I want to implement my own simple property system (C++) similiar to one provided by Qt's Q_PROPERTY. The problem is that Qt's properties doesn't work from inside macros which I'm trying to use to add some additional functionality above properties. The aim is to be able to declare a property and automatically get access both through properties string name representation and regular methods:
MY_PROPERTY(QString, Name)
...
getObject()->setProperty("Name", "John");
...
myObject->setName("John");
QString name = myObject->getName();
I want to add all the needed functionality with a single line but the following code will not work, since MOC doesn't expand macros:
#define MY_PROPERTY(type, name)\
Q_PROPERTY(type name READ name WRITE change##name)\
\
void set##name(type param)\
{\
m_##name = param;\
DO SOMETHING
}\
Please advice any good books/articles on this topic.
most (>95%) condition, Qt Propery System is enough, if you really want to add something on yourself property when its setting or getting, you can use Qt signal/slot System to do this.
if you finally still want to do you own Property System, I think the best reference is Qt source code, isn't it?

Joomla: Plugins for a plugin - how to 'advertise' capabilities?

I am working on a plugin which will have its own plugins to handle various events.
Now I'm thinking of enabling this plugins to add their own "commands". But I wonder how to treat that most efficiently. I have a list of my own commands which I search in the article anyway. Should I then just trigger a DoWhatYouWant($article)-event - or, since I do the searching (and parsing of params) anyway, perhaps I could build a global command-list and then trigger an "ExecuteCommand($article,$cmd,$params)"-event? Sounds nicer, but then (I think) I'd have to build this command-list (so that my program know what to look for), so every plugin would have to somehow 'advertise' what it could do, i.e. the names of commands it could handle - and I have no idea how that could be done.
Or is there a better (more standardized?) approach?
If you import your plugins trough the plugin helper
JPluginHelper::importPlugin('mycmdplugins');
then you can get all available commands which are supported by your sub plugins like
$cmds = JDispatcher::getInstance()->trigger('onMyAwesomeCmds');
With the $cmds variable you know now which commands are supported by the sub plugins and you can parse the article for them. Then you can do
foreach ($cmds as $cmd) {
preg_match_all("{".$cmd."*}", $article->text, $matches, PREG_SET_ORDER);
if (!empty($matches)) {
JDispatcher::getInstance()->trigger('onMyAwesome'.ucfirst($cmd), array($article, $params));
}
}
To eliminate more repeating tasks I suggest that the additional plugins will extend a base class from your plugins folder.

How can I create a JSON webservice to store and retrieve data from a simple properties file?

How can I create a Java or Javascript JSON webservice to retrieve data from a simple properties file? My intention is to uses this as a global property storage for a Jenkins instance that runs many Unit tests. The master property file also needs to be capable of being manually edited and stored in source control.
I am just wondering what method people would recommend that would be the easiest for a junior level programmer like me. I need read capability at miniumum but, and if its not too hard, write capability also. Therefore, that means it is not required to be REST.
If something like this already exists in Java or Groovy, a link to that resource would be appreciated. I am a SoapUI expert but I am unsure if a mock service could do this sort of thing.
I found something like this in Ruby but I could not get it to work as I am not a Ruby programmer at all.
There are a multitude of Java REST frameworks, but I'm most familiar with Jersey so here's a Groovy script that gives a simple read capability to a properties file.
#Grapes([
#Grab(group='org.glassfish.jersey.containers', module='jersey-container-grizzly2-http', version='2.0'),
#Grab(group='org.glassfish.jersey.core', module='jersey-server', version='2.0'),
#Grab(group='org.glassfish.jersey.media', module='jersey-media-json-jackson', version='2.0')
])
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory
import org.glassfish.jersey.jackson.JacksonFeature
import javax.ws.rs.GET
import javax.ws.rs.Path
import javax.ws.rs.Produces
#Path("properties")
class PropertiesResource {
#GET
#Produces("application/json")
Properties get() {
new File("test.properties").withReader { Reader reader ->
Properties p = new Properties()
p.load(reader)
return p
}
}
}
def rc = new org.glassfish.jersey.server.ResourceConfig(PropertiesResource, JacksonFeature);
GrizzlyHttpServerFactory.createHttpServer('http://localhost:8080/'.toURI(), rc).start()
System.console().readLine("Press any key to exit...")
Unfortunately, since Jersey uses the 3.1 version of the asm library, there are conflicts with Groovy's 4.0 version of asm unless you run the script using the groovy-all embeddable jar (it won't work by just calling groovy on the command-line and passing the script). I also had to supply an Apache Ivy dependency. (Hopefully the Groovy team will resolve these in the next release--the asm one in particular has caused me grief in the past.) So you can call it like this (supply the full paths to the classpath jars):
java -cp ivy-2.2.0.jar:groovy-all-2.1.6.jar groovy.lang.GroovyShell restProperties.groovy
All you have to do is create a properties file named test.properties, then copy the above script into a file named restProperties.groovy, then run via the above command line. Then you can run the following in Unix to try it out.
curl http://localhost:8080/properties
And it will return a JSON map of your properties file.

How do I run some code after every build in scons?

I'm looking for a way to register somthing like an end-build callback in scons. For example, I'm doing something like this right now:
def print_build_summary():
failures = SCons.Script.GetBuildFailures()
notifyExe = 'notify-send '
if len(failures) > 0:
notifyExe = notifyExe + ' --urgency=critical Build Failed'
else:
notifyExe = notifyExe + ' --urgency=normal Build Succeed'
os.system(notifyExe)
atexit.register(print_build_summary)
This only works in non-interactive mode. I'd like to be able to pop up something like this at the end of every build, specifically, when running multiple 'build' commands in an interactive scons session.
The only suggestions I've found, looking around, seem to be to use the dependency system or the AddPostAction call to glom this on. It doesn't seem quite right to me to do it that way, since it's not really a dependency (it's not even really a part of the build, strictly speaking) - it's just a static bit of code that needs to be run at the end of every build.
Thanks!
I don't think there's anything wrong with using the dependency system to resolve this. This is how I normally do it:
def finish( target, source, env ):
raise Exception( 'DO IT' )
finish_command = Command( 'finish', [], finish )
Depends( finish_command, DEFAULT_TARGETS )
Default( finish_command )
This creates a command that depends on the default targets for it's execution (so you know it'll always run last - see DEFAULT_TARGETS in scons manual). Hope this helps.
Ive been looking into this and havent found that SCons offers anything that would help. This seems like quite a usefull feature, maybe the SCons developers are watching these threads and will take the suggestion...
I looked at the source code and figured out how to do it. I'll try to suggest this change to the SCons developers on scons.org.
If you're interested, the file is engine/SCons/Script/Main.py, and the function is _build_targets(). At the end of this funcion, you would simply need to add a call to a user supplied callback. Of course this solution would not be very useful if you build on several different machines in your network, since you would have to port the change everywhere its needed, but if you're only building on one machine, then maybe you could make the change until/if SCons officially provides a solution.
Let me know if you need help implementing the change, and I'll see what I can do.
Another option would be to wrap the call to SCons, and have the wrapper script perform the desired actions, but that wouldnt help in SCons interactive mode.
Hope this helps,
Brady

I create a feature request for this: http://scons.tigris.org/issues/show_bug.cgi?id=2834
