node.js - NodeJS Memory Leak when using VM to execute untrusted code -

-

I am using nodjs to run unreliable code safely. I have seen a huge memory leak which takes about 10 mm of memory on every execution and does not release it. After all, my node process ends up using 500M + memory. After some excavation, I saw the problem in continuous construction of VM. To test my theory, I commented on the code that creates VMs, of course, the memory usage dropped dramatically, I re-dismissed the code again and got global.gc () strategic around problem areas Appeared and divided the node with Exposure -GC flag. It dramatically reduced my memory usage and retains functionality.

Is there a better way to clean VMS that I am using it?

My next approach is the cache which is the vm with the unsafe code and it is reusing it if I see the unsafe code again (background: I Parsing functions, thus, the unsafe code is often executed or executed once

some reference code. 

  async.each (item , Function (i, cb) {// initial reference ... var Reference = Vm.createContext (init); // Captivated untrusted code work executed = vm.runInContext (pars, context); // This dramatically improves usage, but standard API / // global.gc Return results through a callback CB (tap, capped);};    
 
 
 When I see this right, see this  v5.9.0 , It appears that in both cases, both the  node  core patrons and The same programmer Many can do that - we have to wait for the upstream fix in the  v8 .  
 No, you can not do anything about it. This bug was good though catching!

Pass DB Connection parameters to a Kettle a.k.a PDI table Input step dynamically from Excel -

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
