Lost trust in manual QA

At my employer's startup the product footprint has grown so big that I have lost trust in manual QA.  Take an e.g. of today,  last night QA found an issue and then my team mate fixed it, before I woke up I saw that QA passed the ticket in flying colors and they did tested many things like update user, bulk update user.

As there is a release today night, I did a detailed code review of the fix and immediately within 2 minutes I see an issue in the bulk update and the problem was that original developer didnt used DRY. So the team mate had fixed update user and from UI the bulk action would still call updateUser. The other bulk update would be called only when you do import CSV or some other public api.

The point being I have lost trust in manual QA because they really cant regress a ticket using all possible combinations in the short amount of time.

We do a release every 3 weeks and in 2 week is dev and 2 week is QA (2nd week is overlap), but in those 2 week we are always scrambling to get our act in shape so corners has to be cut.  Many times I see QA raising tickets after its live in prod.

The only way here is to remove the human touch point from equation if we want to maintain the same release velocity and code quality.

Logging to Graphite monitoring tool from java

We use Graphite as a tool for monitoring some stats and watch trends. A requirement is to monitor impact of new releases as build is deployed to app nodes to see if things like
1) Has the memcache usage increased.
2) Has the no of Java exceptions went up.
3) Is the app using more tomcat threads.
Here is a screenshot

We changed the installer to log a deploy event when a new build is deployed. I wrote a simple spring bean to log graphite events using java. Logging to graphite is easy, all you need to do is open a socket and send lines of events.
import org.slf4j.Logger;import org.slf4j.LoggerFactory; import java.io.OutputStreamWriter; import java.io.Writer; import java.net.Socket; import java.util.HashMap; import java.util.Map; public class GraphiteLogger { private static final Logger logger = LoggerFactory.getLogger(GraphiteLogger.class); private String graphiteHost; private int graphitePort; public String getGraphiteHost() { return graphiteHost; } public void setGraphite…

Jersey posting multipart data

This took me sometime to figure out mostly it was because I was only including jersey-multipart-1.6.jar but I was not including mimepull-1.3.jar.

So the intent is to upload a file using REST api and we need pass meta attributes in addition to uploading the file. Also the intent is to stream the file instead of first storing it on the local disk. Here is some sample code.
@Path("/upload-service") public class UploadService { @Context protected HttpServletResponse response; @Context protected HttpServletRequest request; @POST @Consumes(MediaType.MULTIPART_FORM_DATA) @Produces(MediaType.APPLICATION_JSON) public String uploadFile(@PathParam("fileName") final String fileName, @FormDataParam("workgroupId") String workgroupId, @FormDataParam("userId") final int userId, @FormDataParam("content") final InputStream content) throws JSONException { //.......Upload the file to S3 or netapp or any storage service } }
Now to tes…
