[JOB] Clojure Selenium Load Testing Consultant
Here at DiligenceEngine we’re building out a load testing system for our Om-based ClojureScript and Clojure web application. We need to scale out test scenarios to 500+ concurrent users are looking for someone experienced in writing selenium tests in Clojure to give us a hand. Required skills - Clojure Very much desired skills - Selenium WebDriver (clj-webdriver or java selenium APIs) - Coding to AWS EC2 APIs (amazonica or similar Clojure wrapper, or java APIs) - Linux (CentOS in particular) in AWS (cloud-init, similar processes) - Knowledge of Clojure/Selenium based cloud technologies we might use to speed our goals Nice to have skills - Selenium related tools such as Selenium Grid - Traditional load testing tools (and knowledge of their limitations) such as LoadRunner This job would last 1-2 months and can start immediately. Remote is welcome, though we prefer someone in a north american time zone to make communication easier. If you are interested please get in touch at j...@diligenceengine.com -- For those interested, our application is a single-page app using ClojureScript and Om on the client and Clojure on the server. It is a highly dynamic app, every single change to the database results in automatic updates being sent out to all clients watching the relevant resources. We use a combination of REST routes for change requests and browserchannel for async push of data updates to make this happen. Unfortunately, these technologies have also made it quite challenging to load test. In particular, we’ve found that it is difficult to get most traditional load testing tools to work well with browserchannel. For this reason we’ve settle on Selenium to simulate load. We’re using AWS to host and build our testing environment. -- You received this message because you are subscribed to the Google Groups Clojure group.

Remember old namespace when using in-ns
I have a peculiar problem (due to being used in a scripting context) related to in-ns. I have a file that is executed in a namespace which is provided by the scripting infrastructure (per invocation, i.e. I do not know the namespace statically,it will be something like prefix.unknown-123). This namespace contains a var, say, x. Now I can switch to a known namespace (I'll call it prefix.known): (in-ns 'prefix.known) but I can no longer use x, because x dose not exist, but prefix.unknown-123/x exists, but I don't know the name of the generated namespace. Now, I could remember the namespace at the time of script invocation with *ns*, but where can I store this reference in a way that is accessible later after switching to the namespace prefix.known? TL;DR: how can I propagate vars from the current namespace when switching to a new namespace using in-ns? -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: XPATH/XSLT like access to Clojure data structures?
This seems to work on XML/JDOM - right? I'm looking for something that works on Clojure data structures. And I wouldn't like to go from Clojure data structures-XML/JDOM only to do the transformation on XML/JDOM and then back to Clojure data structures.

Re: cascalog and java 1.7
Hey Sunil, That's probably due for an update. Hadoop 1.x (and 0.21.x, etc) only ran on JDK6. As long as the Hadoop distro you've chosen runs on JDK6 or JDK8 you're going to be fine. Cheers, Sam Sunil S Nandihalli mailto:sunil.nandiha...@gmail.com February 26, 2015 at 1:25 PM Hi Everybody, I have been meaning to try cascalog for a while now looking at its powerful query language. But today when I was trying to play with it I am getting some errors and when I go back cascalog readme page it says cascalog runs only with java 1.6 . Is it just that the readme is outdated or does it really mean that cascalog cannot run on java 1.7? I thought I need to confirm this before investigating cascalog any further.

Re: Reflection warning on setCaretPosition

Re: Is it possible to determine that I did a 'lein repl'

Here’s how we do it. Add the following to project.clj:
:profiles {:repl {:jvm-opts ~(conj (jvm-opts) -Dlein.profile.repl=true)}}
jvm-opts is a function in project.clj that returns the default JVM options — we
do different things on different platforms — it returns a vector of JVM
options. So :jvm-opts [-Dlein.profile.repl=true] might be sufficient for you.
Then in our code we test:
(System/getProperty lein.profile.repl)
This will be true if you’re in a REPL and nil otherwise.

Re: Reflection warning on setCaretPosition
If (text ...) is an invocation of a macro, not a function, then that type tag is most likely silently ignored by the Clojure compiler, not hurting anything, but not helping anything, either. Eastwood [1] can warn you about such useless type tags in your Clojure code, via the :unused-meta-on-macro [2] linter. Some other incorrect type tags are checked for via the :wrong-tag linter [3]. Not all kinds of Eastwood checks are enabled by default, but those two are.

Re: XPATH/XSLT like access to Clojure data structures?
Sorry, please ignore me. I misread your post entirely :-). I think clojure.zip and clojure.data.zip (not the XML parts) will get you partway to where you want, but I do not know of any XPATH-like API over the top of them.

Re: Is it possible to determine that I did a 'lein repl'
I had exactly that problem when using an old version of JDAF. The newer
version makes it configurable.
to get around the problem i used AspectJ like this:
@Aspect
public class SystemExitEvader {
@Pointcut(call(* java.lang.System.exit(..)) args(status))
public void systemExitCall(int status){}
@Around(systemExitCall(status))
public void doNothing(ProceedingJoinPoint thisJoinPoint, int status){
System.out.println(Call to System.exit() attempted);
// note: there is no call to proceed()
}
}
btw, if you have any java code still, take a look at DCEVM
https://dcevm.github.io/ which makes the whole 'develop java gui from
repl' experience much better.

Re: should edn recognise defrecord?
http://www.compoundtheory.com/clojure-edn-walkthrough/ is a nice read
around this as well.

The defrecord is defined using cljx and is definitely there on the server.
Do I need to write a reader function to recognise instances of defrecord -
my assumption was that this should just work?
Thanks!

Re: Reflection warning on setCaretPosition
It means the Clojure compiler cannot emit the efficient bytecode directly, so it emits bytecode that calls the method reflexively. This only impacts performance, so if that code is not used much, it is not a problem. The underlying problem is that jvm bytecode is typed, so ideally the bytecode should be able to say call method M of type T on object O. Here, the Clojure Compiler cannot infer a type for html-table, so instead the emitted bytecode is more along the lines of ask object O to give a list of all of its types, then look into each of these types to find if one has a method that matches M in terms of name and number of arguments, and then look at that method's signature and check if the arguments can be cast to the types of the formal parameters; if there is a type with such a method, invoke that method. This is not 100% technically accurate (in particular, i have no idea what reflection does about the arguments and their types in this case), but it should be roughly correct and you can easily see why that would be much slower. If you want to remove that warning, you can annotate the html-table variable, but the place where you must do that will depend on a little more context than what you've given here. It is usually done at the level of var declaration or in function argument lists.

Re: Is it possible to determine that I did a 'lein repl'
Well, I dont know if you could. but unless anyone else chimes in with
another solution... there's no problem using clojure and java together in a
lein project.
And just to check ... this system/exit call is library code you have no
control over right? I mean, if not of course you can stick a *when* block
around it looking for a system property set from the repl or something
along those lines.

I had exactly that problem when using an old version of JDAF. The newer
version makes it configurable.
to get around the problem i used AspectJ like this:
@Aspect
public class SystemExitEvader {
@Pointcut(call(* java.lang.System.exit(..)) args(status))
public void systemExitCall(int status){}
@Around(systemExitCall(status))
public void doNothing(ProceedingJoinPoint thisJoinPoint, int status){
System.out.println(Call to System.exit() attempted);
// note: there is no call to proceed()
}
}
How would I implement this in Clojure?

Re: How do I depend on clojure 1.7.0-master-SNAPSHOT?
Sean, thanks - but does it still work for you if you remove ~/.m2/ (or just remove 1.7.0-master-SNAPSHOT from here)? I've tried with the trailing slash and am still having no luck (both locally and on Travis CI). Andy, having this as a dependency was working previously but I will clone and build master directly in the meantime - thank you.

Is it just that the readme is outdated or does it really mean that cascalog cannot run on java 1.7? I thought I need to confirm this before investigating cascalog any further.
